This paper presents the simple method to determine the complex stress intensity factor of interface crack in bi-material plate under bending. In the present method, the stress values at the crack tip calculated by FEM are used and the stress intensity factors of interface crack are evaluated from the ratio of stress values between a given and a reference problems. A single interface crack in an infinite bi-material plate subjected to tension and shear is selected as the reference problem in this study. The accuracy of the present analysis is discussed through the results obtained by body force method. As the result, it is confirmed that the present method is useful for analyzing the interface crack under bending.

Bi-modulus materials exhibit the different modulus in tension and compression. The value of elastic modulus and Poisson ratio of every point in the bi-modulus elastic body not only depend on the material itself, but also the stress state and the strain state of the point. The uncertainty and nonlinearity of the elastic constitutive relation result in that the bi-modulus elastic problem is the complicated nonlinear problem This paper aims at studying the bi-modulus elastic constitutive equation employed in the bi-modulus finite element numerical method (FEM). The new elastic matrix model is proposed based on Ye’s principal strain criterion with the assumption that the Poisson ratio maintain constant whenever in tension or in compression, and the elastic matrix is symmetric by equivalent transmitting. The shear modulus expression of this elastic matrix model is derived to enable the elastic matrix completely and improve the convergence of the FEM calculation. The statically indeterminate bi-modulus beam is analyzed by means of FEM employing the proposed elastic matrix model. The effects of the tensile modulus to compressive modulus ratio and the boundary condition on the stress and deflection of the bi-modulus beam is studied.

For the conducting body coated with thin-layer material, plenty of fine meshes are required in general. In this paper, shell vector element (SVE) is used for modeling of thin coating dielectric. Further, a domain decomposition (DD) method for hybrid shell vector element method boundary integral (SVE-BI) is proposed for analysis of electromagnetic problem of multiple three-dimensional thin-coating objects. By this method, the whole computational domains are divided into sub-SVE domains and boundary element domains. With shell element, not only the unknowns are far less than the one by traditional vector element method, but only surface integral is required. The DDM framework used for hybrid SVE-BI also enhances the computational efficiency of solving scattering from multiple coating objects greatly. Finally, several numerical examples are presented to prove the accuracy and efficiency of this DDM-SVE-BI method.

The finite element boundary integral (FEM-BI) method is widely used in the scattering and radiating problems. But for the conducting body coated by thin-layer material, plenty of fine meshes are required to discretize the geometry in the traditional FEM. It requires very expensive storage and CPU time. In this paper, the hybrid shell vector element with the boundary integral method is used to expedite the solution of thin coating problems. The shell vector elements are used to discretize thin-layer material instead of traditional tetrahedral elements. Consequently, the volume integral can be simplified into surface integral. This method reduces the number of unknowns greatly and is also extended into the complicated case of multi-thin-layer coating materials. Several numerical results are presented to prove the accuracy and efficiency of this present method.

The objective of this article is to explain the dominance and advocacy of the design- oriented research approach in Wirtschaftsinformatik (Business Informatics or BI), one of the major Information Systems (IS) communities. To this end, we employed a research approach based on autobiographical material. Sixteen well-known BI scholars served as informants, and provided career autobiographies in which they document their perceptions and observations regarding the genesis and development of BI. The average age of this sample of contemporary witnesses is 70 years, signifying a rich body of experience. Based on an interpretive analysis of the data, we find that the design of IS is deeply rooted in BI's history, and our results also show that there have always been close relationships with practice. As a consequence, we conclude that the success of BI as an academic community is inseparably associated with systems design, implementation, and engineering. Against this background, we argue that it is unlikely that BI will weaken its design orientation in the future, although external forces signify a shift to a more behaviouristic research approach. In order to balance the internal strength of the community and the external forces, we suggest a ‘theory-driven design approach’ as a viable strategy for the future orientation of the community.

Small Butterfly valve is specially designed for use in industry field and ship. The important parts of butterfly valve are composed of disk, stem and body. But, like LNG ship, in enviroment of low temperature, as working condition deteriorates, important of sealing more increased. In this study, we examine sealing mechanism of butter valve on the base of FEM and investigate sealing life by measurement. The finite element analysis was carried out to study the effect of the seal ring shape on bi-directional sealing force of valve. The sealing mechanism was evaluated by 2-dimensional model in order to save the analysis time. And these analyses used by material non-linearity and contact element were implemented.

BACKGROUND: This paper outlines a method to study the interaction between the human body and the aircraft seat concerning the seat comfort. METHOD: Firstly, the human body is modeled based on biomechanics and divided into a number of body segments connected by joints according to human anatomy. The angles between the body segments are obtained by curve fitting of the existing biomechanical research data. The contact forces between the human body and the seat are modeled using pairs of bi-lateral point forces. These forces are calculated and located through the analysis of the center of gravity of each body segment and average muscular structure of the human body. The geometry of the human and the seat is obtained from a 3D scan model or a CAD model. Secondly, the pressure distribution between the human body and the seat is modeled and calculated using the contact stress theory. The results of the two parts are combined to analyze the comfortability in relation to different postures, backrest recline angles and changing in shape and material. RESULTS: Simulations were performed and they are compared with experimental measurement and various FEM studies for validation. It is found that accuracy of this method is comparable with most FEM calculation. CONCLUSION: This method provides a new direction in cushion conform research. It is faster and convenient to use comparing to the FEM, and the result is reliable.

Background High b-value diffusion-weighted imaging has application in the detection of cancerous tissue across multiple body sites. Diffusional kurtosis and bi-exponential modeling are two popular model-based techniques, whose performance in relation to each other has yet to be fully explored. Purpose To determine the relationship between excess kurtosis and signal fractions derived from bi-exponential modeling in the detection of suspicious prostate lesions. Material and Methods This retrospective study analyzed patients with normal prostate tissue (n = 12) or suspicious lesions (n = 13, one lesion per patient), as determined by a radiologist whose clinical care included a high b-value diffusion series. The observed signal intensity was modeled using a bi-exponential decay, from which the signal fraction of the slow-moving component was derived ( SFs). In addition, the excess kurtosis was calculated using the signal fractions and ADCs of the two exponentials ( KCOMP). As a comparison, the kurtosis was also calculated using the cumulant expansion for the diffusion signal ( KCE). Results Both K and KCE were found to increase with SFs within the range of SFs commonly found within the prostate. Voxel-wise receiver operating characteristic performance of SFs, KCE, and KCOMP in discriminating between suspicious lesions and normal prostate tissue was 0.86 (95% confidence interval [CI] = 0.85 – 0.87), 0.69 (95% CI = 0.68–0.70), and 0.86 (95% CI = 0.86–0.87), respectively. Conclusion In a two-component diffusion environment, KCOMP is a scaled value of SFs and is thus able to discriminate suspicious lesions with equal precision . KCE provides a computationally inexpensive approximation of kurtosis but does not provide the same discriminatory abilities as SFs and KCOMP.

Objective. Direct-current electrical cardioversion is the main method for the conversion of atrial fibrillation. Its success depends on many factors. In several studies, biphasic shock waveforms have been demonstrated to be superior to monophasic shocks for termination of atrial fibrillation; however, information about impact of paddle position is controversial. Initial energy level is an object of discussions. The aim of the study was to compare a truncated exponential biphasic waveform with monophasic damped sine waveform and antero-lateral with antero-posterior paddle positions for cardioversion of atrial fibrillation, to determine its impact on early reinitiation of atrial fibrillation. Material and methods. A total of 224 consecutive patients with atrial fibrillation underwent electrical cardioversion with biphasic (Bi, n=112) or monophasic (Mo, n=112) shock waveform in a randomized fashion. The position of hand-held paddle electrodes was randomly selected in both groups to be anterior-lateral and anterior-posterior. Energies used were 100–150–200–300–360 J (Bi) or 100–200–300–360 J (Mo). If monophasic shock of 360 J was ineffective, we used biphasic shock of 360 J. Early recurrent atrial fibrillation (ERAF) was defined as a relapse of atrial fibrillation within 2 min after a successful cardioversion, acute recurrent – within 24 h. Results. Two study groups (Bi vs Mo) did not differ with regard to age, body mass index, duration of AF episode (mean 98±147 days for the Bi group and 80±93 days for the Mo group, P=0.26), underlying heart disease, left atrial diameter, left ventricular ejection fraction. In the Mo group, more patients used amiodarone (59.82% vs 41.97%, P=0.002), in the Bi group more patients used propafenone (16.07% vs 8.93%, P=0.033). Cardioversion success rate was 97.32% in the Bi group and 79.46% in the Mo group (P<0.001). After biphasic shock of 360 J in Mo group, the cumulative success rate was 99.11%. Mean delivered energy and mean number of shocks were significantly lower in the Bi group (198.5±204.4 J, 1.5±0.9 shocks vs 489.1±464.2 J, 2.4±1.5 shocks). The efficacy of first shock was 66.96% in the Bi group and 37.5% in the Mo group (P<0.0001). Incidence of ERAF was 4.46% in both groups. Paddle position had no impact on efficacy of cardioversion and ERAF. Conclusions. For the cardioversion of atrial fibrillation, biphasic shock waveform has a higher success rate than monophasic shock waveform. We did not observe the influence of paddle positions on efficacy of cardioversion. Shock waveform and paddle position had no impact on ERAF. We recommend starting with biphasic energy of 150 J and monophasic of not less than 200 J for cardioversion of atrial fibrillation.

Patients with lepromatous leprosy that have received treatment for many years usually get follow up biopsies for persistent skin lesions or positive bacilloscopy even if the values are lower than in the initial bacilloscopy.We report the case of a 48-year old woman with long-standing lepromatous leprosy of 15 years of evolution, with a bacterial index of 4 in the direct smear and the initial skin biopsy.The patient was treated with multidrug therapy for 32 months although the treatment recommended by the World Health Organization (WHO) is only for 12 months.A skin biopsy was taken to determine if there was an active disease. We observed a diffuse dermal inflammation with numerous foreign body giant cells and vacuolated macrophages (Virchow´s cells). These cells contained granular acid-fast material that was also positive with immunohistochemistry for BCG. There were fragmented bacilli and the BI was 2.These cells were also strongly positive for CD68. The biopsy was interpreted as a residual form of lepromatous leprosy that did not require further multidrug therapy.We have observed similar histological profiles in several cases. The lack of clinical data makes it a histological challenge. The accumulation of lipids in these giant cells is due to bacillary destruction and fusion of vacuolated macrophages. We discuss here the role of bacillary and host lipids in the pathogenesis of lepromatous leprosy. We concluded that there was no need to extend the 12-month multidrug therapy recommended by WHO.

In modern manufacture, like in automotive industry, high quality products and high output rates as well as low costs are achieved by highly efficient processes. Optimized tool design represents a key factor for such processes, leading to long tool life and hence to low tooling costs. Early in the industrial manufacturing chain of roller bearings for example, hot bars are sheared into billets, which are subsequently transported automatically to the first forming stage of a press. The shear blades should have a high wear resistance at high temperatures. In this study the first bi-metal composite shear blade made by spray-forming has been developed and tested in industrial environment. The composite tool has been deposited in a co-spray forming process to directly combine a hard-facing alloy layer with a hot working steel body in order to take advantage of the high microstructural homogeneity and the low segregation generated in spray forming. After machining, heat treating and quality inspection of the new material composite, the hot working tool was used in manufacture to prove its wear resistance and durability. The results show that the interface properties of the composite are of high quality and the material has a lower vulnerability to cracks after use in production than the conventional tool, respectively material. Only the porous zone near the interface leads to fissures which are partially going deep into the tool. Hence the parameters of the co-spray forming process need to be improved.

Material selection is the key issue when developing a biocompatible packaging process for implantable electronic systems. To secure a reliable performance of the chip in such a package, its encapsulation has to be considered up-front in the wafer-level integration scheme. A differentiation of two main material types can be made:1) Insulating or passive materials functioning as a bi-directional diffusion barrier preventing body fluids leaking into the package causing systems malfunction due to possible materials corrosion and also avoiding a leakage of built-in materials to the in-vivo environment and2) Conductive or active materials as diffusion barriers, e.g. against copper diffusion or as direct external contacts responsible for electrical performance of the system. This study investigates the properties of two widely used insulating materials in the semiconductor industry, the nitride and the oxide. Both material types are deposited in a PECVD system using different temperatures; 400 ° C for CMOS compatibility and 200 ° C for wafer back side process integration when a temporary carrier system is used. The biocompatibility investigations of these materials (evaluated using cell lines and primary cells) show promising results. However, for the long term application, the stability results for the oxide layers show hydration effects resulting in material degradation where the nitride layers clearly show corrosion and are even etched when elevated temperatures are applied. This fact is surprising since nitride layers are widely used as a humidity barrier for various chip types but obviously not suitable for a direct contact with liquids. Various analysis methods using e.g. Fourier Transformed IR Spectroscopy or mass measurements substantiate this thesis.

A biocompatible packaging process for implantable electronic systems is under development at imec, combining biocompatibility, hermeticity, extreme miniaturization and cost aspects. In a first phase of this packaging sequence, hermetic chip sealing is performed by encapsulating all chips to realize a bi-directional diffusion barrier preventing body fluids to leach into the package causing corrosion, and preventing IC materials such as Cu to diffuse into the body, causing various adverse effects. For cost effectiveness, this chip sealing is performed as post-processing at wafer level, using modifications of standard clean room (CR) fabrication techniques. Well known conductive and insulating CR materials are investigated with respect to their biocompatibility, biostability, diffusion barrier properties and sensitivity to corrosion. Material selection and integration aspects are modified until good properties are obtained. In a second phase of the packaging process, all chips of the final device should be electrically connected, applying a biocompatible metallization scheme. We selected the use of Pt due to its excellent biocompatibility and corrosion resistance. Since Pt is very expensive, a cost effective Pt-selective plating process is developed. During the third packaging step, all system components such as electronics, passives, a battery,… will be interconnected. To provide sufficient mechanical support, all components are finally embedded using a medical grade elastomer such as PDMS or Poly-urethane.

This paper presents the morphological capillary-porous structure analysis of sunflower seed, using X-ray microtomography in the longitudinal and transverse section and FESEM analysis of the surface microstructure after novel technologies treatment. Two types of treatment are considered: pulsed electric field treatment that has electroporation effect of the oil cell structure and pulsed microwave treatment that affects the internal structure. The main characteristic of the capillary-porous structure of oil-bearing material is given. Air cavities in the structure of the sunflower kernels were observed using X-ray microtomography. The influence of a pulsed electric field treatment on structure integrity of sunflower cells has been obtained with the creation of a material that has a greater permeability for diffusion processes. Experimentally was determined that over 2500 electric pores were formed on an area of 1 cm2 as a result of a pulsed electric field treatment. In the case of a pulsed electric field treatment, the oil seed body model can be represented as a bi-dispersed structure with the addition micro capillaries, formed by an electric field. It was experimentally defined that pulsed microwave treatment affected of internal seed structure. Denaturation of proteins and breakage of oil globules after pulsed microwave treatment decreased dispersion of the sizes of particles approximately twice with 35.3 μm2 up to 18.1 μm2. The data obtained are of interest not only for the technology of processing oilseeds but also for the analysis of novel emerging technologies.

Aim. Evaluation of the ability of fixed combination of perindopril and indapamide (Noliprel Bi Forte) to achieve additional angioprotection in patients with arterial hypertension already reached target blood pressure (BP) at previous antihypertension therapy with losartan and hydrochlorothiazide (HCT).Material and methods. To open observational study, lasting 12 weeks, 25 patients included, those who had been taking losartan+HCT 100/12,5 mg. Results. During the study, all patients underwent 24 hour BP monitoring, applanation tonometry (augmentation index assessment and of central BP), measurement of pulse wave velocity (PWV), laboratory tests (lipids, fasting glucose, HOMA index, homocystein, leptin, adiponectin, high-sensitive C-reactive protein (hsCRP), vascular age assessment). After shifting the therapy with losartan and HCT to combination perindopril and indapamide, BP decreased additionally by 3,9%, and diastolic BP — 5,4% (p<0,05). There was decrease of augmentation index by 9,4% and vascular age by 6,0% (p<0,05). There was also decrease of leptin level by 14,5%, hsCRP by 11,0%, and increase of adiponectin by 9,9% (p<0,05).Conclusion. The fixed combination perindopril and indapamide does have advantages for losartan and HCT combination in BP control, vascular elasticity improvement, and facilitates the decrease of body mass index, insulin resistance and non-infectious inflammation.

A set of Mindlin plates bonded together is subjected to loading by impact, which is considered to represent a generic engineering structure and is analyzed through numerical simulation. The objective is to identify optimum configuration in terms of loading, structural dimensions, material properties and composite layup associated with micrometeorites impacts on spacecraft that will not penetrate into its structure. Following the algorithm developed for the problem, the work comprises an in-depth analysis of a generic flat plate structure subjected to impact and numerical simulation. The analyses are based on dynamic response with emphasis on the elastic region. The direct numerical simulation is carried out in parallel for the analysis, synthesis, parametric study and optimization. As simulation case study, the panel structure response to impact loading by a spherical rigid body at certain velocity perpendicular to the panel plate itself and numerical simulation is carried out as appropriate. Simulation results are validated through comparison with analytical work. The entire scheme carried out in this work is a novel comprehensive approach for the structural design of non-penetrated impact on metallic composites. The results show that the use of composites, in particular the bi-metallic composite, is instrumental in tailoring the plate materials to achieve non-penetrating impact.

Finite element models (FEMs) derived from QCT-scans were developed to evaluate vertebral strength but QCT scanners limitations are restrictive for routine osteoporotic diagnosis. A new approach considers using bi-planar dual energy (BP2E) X-rays absorptiometry to build vertebral FEM. The purpose was to propose a FEM based on BP2E absorptiometry and to compare the vertebral strength predicted from this model to a QCT-based FEM. About 46 vertebrae were QCT scanned and imaged with BP2E X-rays. Subject-specific vertebral geometry and bone material properties were obtained from both medical imaging techniques to build FEM for each vertebra. Vertebral body volumetric bone mineral density (vBMD) distribution and vertebral strength prediction from the BP2E-based FEM and the QCT-based FEM were compared. A statistical error of 7[Formula: see text]mg/cm3 with a RMSE of 9.6% and a [Formula: see text] of 0.83 were found in the vBMD distribution differences between the BP2E-based and qCT-based FEM. The average vertebral strength was 3321[Formula: see text][Formula: see text] and 3768[Formula: see text][Formula: see text] for the qCT-based and BP2E-based FEM, respectively, with a RMSE of 641[Formula: see text]N and [Formula: see text] of 0.92. This method was developed to estimate vBMD distribution in lumbar vertebrae from a pair of 2D-BMD images and demonstrated to be accurate to personalize the mechanical properties in vitro.

Flow and fracture of some soft solids may be described by the ‘solid’ mechanical properties of elastic modulus, yield stress and fracture toughness, all being dependent on rate, temperature and environment. Other soft solids behave more like very viscous materials. When cutting soft solids, friction is often high between the blade and the material, and cutting is made easier when performed with a thin wire. The wire may be held taut in a frame like a fretsaw, but cutting is often done using an initially slack wire pulled into the solid by hand or machine. For both types of material behaviours, we investigate the curved shape taken by a loaded wire, elements along which cut into the material both radially and tangentially. For soft materials displaying solid properties, the treatment is based on the analysis of bi-directional cutting by Atkins et al . (Atkins et al . 2004 J. Mater. Sci. 39 , 2761–2766), in which it was shown that the ratio ξ of tangential to radial displacements strongly influences the cutting forces. The shapes of wires of various lengths arranged as bowstrings, and the loads in the wires, are assessed against experiments on cheddar cheese. The resultant force takes a minimum value for a particular length of the wire, owing to the competition between lower cutting forces, but higher friction at large ξ and vice versa. Passage of a wire through very viscous materials is flow at very low Reynolds number. To determine the path swept out, we make use of the property of all slender bodies of revolution in highly viscous flow, namely, that the drag exerted across the body is approximately twice as large as along. Comparison is made with the experiments on weighted threads falling under gravity in glycerine. Regelation is another example of passage of a wire through a solid. The mechanism is completely different but, in the context of the present paper, we provide in appendix A the solution for the typical hours-long school demonstration where, unlike most reported studies, non-uniform temperature fields develop in the block of ice. Comparison is made with experiment.

Onomastic walk through the streets of the Belgrad zooThis article discusses urban names found in the zoo in Belgrad. The article is an attempt to find out why the managers of the zoo decided to transpose urban names into the area of the zoo and in what categories we can perceive this choice.The body of material, including 36 onymic units, was subject to semantic and formal analysis. The material includes commemorative names referring i.a. to the first names and surnames of the zoo directors, figures connected with science and culture, or the names of institutions supporting the zoo. The vast majority of them are formal language structures, especially genitive forms.The presented semantic and formal models follow the convention of the contemporary nomenclature of streets in Belgrad. The very transposition must be regarded as innovative, determined on the one hand by the development of mass culture and on the other hand by political reasons, which can be perceived in the category of patriotism with a slightly nationalistic tinge.Onomastička šetnja stazama Beogradskog zoološkog vrtaČlanak se bavi gradskim nazivima koji su zabeleženi na terenu Beogradskog zoološkog vrta.

Sakupljeni materijal predstavlja nazive koji su svojevrsna vrsta sećanja, a čija se motivacija, između ostalog, odnosi na imena i prezimena direktora zoološkog vrta, osoba povezanih sa naukom, kulturom, kao i nazivi institucija koje podržavaju zoološki vrt. Uglavnom su to strukture sa formalnojezičkom kreacijom, usred kojih dominiraju forme genitiva.Predstavljeni semantički i formalni modeli uklapaju se u konvenciju savremenih naziva beogradskih ulica. Samu transpoziciju bi trebalo smatrati za inovatorsku koja je sa jedne strane determinisana razvojem masovne kulture, a sa druge političkim povodima koji se mogu analizirati u patriotskim kategorijama sa izvesnom dozom nacionalizma.

Background Obesity is a major public health disorder associated with multiple co-morbidities. Knee magnetic resonance imaging (MRI) permits visualization of the subcutaneous fat anatomy, which can be correlated to body mass index (BMI) and obesity-related co-morbidities. Purpose This study intends to validate a method of correlating measurements of subcutaneous fat around the distal femur on axial MR images to BMI and obesity-related co-morbidities. Material and Methods The most proximal axial slice of each knee MRI was divided into four quadrants. Measurements of the thickest portion of the subcutaneous fat in each quadrant were independently obtained, yielding a value which was assigned the name of the SubCut fat index. The relationship between the SubCut fat index of each quadrant and the patient’s BMI was then evaluated. Receiver operating characteristic curves utilizing both the subcutaneous fat in the medial and lateral quadrants as well as BMI were performed with respect to obesity-related co-morbidities. Results SubCut fat index measurements in all four quadrants and BMI show the strongest correlation (all four, ANOVA P < 0.0001, r = 0.6), with subcutaneous fat measurements of the anterior medial (p < 0.0001) and posterior medial quadrants ( P = 0.01). Additionally, BMI and medial quadrants SubCut indices showed strong association with obesity-related co-morbidities including sleep apnea, asthma, diabetes, hypertension, gastroesophageal reflux disease, and osteoporosis. Conclusion The SubCut fat index, a marker of distal femur subcutaneous fat on axial MRI, correlates with severity of obesity (BI) and associated obesity-related co-morbidities.

Abstract Introduction/Objective Follicular dendritic cell sarcoma (FDCS) is the malignant counterpart of the germinal center follicular dendritic cell. Cytomorphological descriptions are few, with only 24 prior cytology reports from 22 publications. We present 4 cases with the aim of adding to this small body of literature. Methods Our database was searched for “dendritic cell.” Patients diagnosed with FDCS that had a cytology specimen were included. Clinical and cytologic features were tabulated. Results Case 1 was an 87-year-old man with a retroperitoneal mass. Aspiration rendered a new diagnosis of FDCS, supported cell block immunohistochemistry. Case 2 was an aspiration of metastatic FDCS to the lung in a 40 year-old- man with a known neck primary. Case 3 was a 46-year-old-man with a left neck mass. Aspiration rendered a misdiagnosis of “atypical epithelioid cells in a background of granulomatous inflammation”. Subsequent needle biopsy confirmed FDCS. Case 4 was an aspiration of metastatic FDCS to the liver in a 66 year-old-woman with a known splenic primary. Comparison of cytomorphology show identical features in all cases. Smears were hypercellular and composed of variably sized syncytial aggregates as well as individually dispersed cells. Tumor cells were variably epithelioid to spindled, had fine chromatin and small nucleoli, displayed frequent bi- and multinucleated forms, and had abundant pale cytoplasm with long, slender fibrillar processes. All cases demonstrated many small lymphocytes intermixed both within the syncytial aggregates and dispersed in the background. Conclusion Cytomorphological features of FDCS appear conserved from case to case. Knowledge of these features may aid in its recognition in aspiration material.

With the purpose of collecting macroinvertebrates for benthic studies of hill streams of the Argentinean Pampean ecoregion, a sampling program was performed in different seasons during 2015. The ingolfiellid crustaceans described in this paper were found only in May 2015 in a sector of the rithron of the Ventana Stream located below the point of the upwelling of hyporheic water, 50 m upstream where the stream is covered by larger conglomerates. The specimens (5 females and 4 males) were measured and photographed, and some were dissected and mounted in Euparal. Appendages of head, pereion and pleon were illustrated. The analysis of the examined material allowed us to conclude that it constitutes a new taxon, Yacana ventania n. gen. n. sp., enlarging the distribution of the family Ingolfiellidae in South America. Characteristics: body long and thin; without eyes; short antennae; inner seta of the outer lobe of maxilla1 is bi-dentate, vestigial molar process and serrations on one side, three spine row elements decreasing in size and the last one toothed; labium present; gnathopod 1 and 2 with a notch on the inner side of the carpus, the carpus of gnathopod 1 has three spines, the proximal one is on the top of a finger-shaped process, while the carpus of gnathopod 2 presents just two spines, propodus in both gnathopods with finger-shaped process at its distal end, a tiny spine and a seta; pereiopods dissimilar, with seta and terminal claw; pereiopod 7 differs from the others in size, number and arrangement of its setae. Uropod 2 longer than uropod 1, uropod 3 small and uniramous; sexual dimorphism clearly present in pleopods and uropod 2 because the females present more rows of setae than males, and probably in the setation of pereiopod 7. Sizes of specimens varied between 3–8.8 mm. The cladistic analysis (TNT) demonstrates that Yacana ventania n. gen. n. sp. is closely related to South African genera because of the vestigial mandibular palp, also the new taxon here described shared the sexual dimorphism with Stygobarnardia and Trogloleleupia, its discovery gaining relevance on biogeographical aspects and providing new evidence to the theory of continental drift. Type specimens are deposited in the Carcinology Collection of the División Zoología Invertebrados, Museo de La Plata, Argentina.

Bi2Se3 has recently become the focus of research development due to its unique transport properties. It is a narrow band gap semiconductor with conducting states on its surface. A reliable and accurate calculation of the optical spectra including excitonic effects is very limited for this material. One of the reasons is that such calculations are computationally demanding since they require a very dense k-point sampling of the Brillouin zone. In this work, we use density functional theory as implemented in Quantum Espresso package to calculate the ground state properties of this material. Optical spectra are calculated within many-body perturbation theory by solving the Bethe-Salpeter equation in Yambo code to account for electron-hole interaction. A double-grid method implemented in Yambo helps us to do accurate calculations of the optical spectra with inexpensive computational cost. Furthermore, we expect that in bulk semiconductor with a narrow gap, electron-electron interaction is weak due to environmental screening. For this reason, to reduce the computational efforts, in this work we neglect the electron-electron interaction.

Abstract Expression levels of miR-29 family members (i.e. miR-29a, miR-29b, & miR-29c) are deregulated in various neoplastic diseases, including acute myeloid leukemia (AML), known to affect DNA-methylation profiles by targeting epigenetic modifiers, & have been shown to be important for normal hematopoietic stem cell function. Mir-29 is organized in two distinctively regulated bi-cistronic clusters: the miR-29a/b-1 cluster & the miR-29b-2/c cluster. Here we evaluated the biological associations & clinical impact of the differential expression of pre-miR-29a/b-1 & pre-miR-29b-2/c clusters in AML. We analysed121 AML patients (pts) (median age 63 years [y], range 37-75 y) who have been consolidated with hematopoietic stem cell transplantation following non-myeloablative conditioning (nma-HCT; Fludarabin 30 mg/m2 on day -4 till -2 & 2 Gy total body irradiation) between 2000 & 2014 with pretreatment bone marrow material (BM) available. Disease status at nma-HCT was first (CR1 62%) or second complete remission (CR2 18%) or CR with incomplete peripheral recovery (CRi 20%). The mutation status (mut) of the ASXL1, CEBPA, DNMT3A IDH1, IDH2, NPM1, & TP53 gene & the FLT3-ITD & EVI1 expressionstatusas well as common surface marker expressions were assessed at diagnosis. European LeukemiaNet (ELN) classification was favorable (25%), intermediate-I (23%), intermediate-II (21%), adverse (27%) or unknown (4%). Pretreatment pre-miR-29a/b-1 & pre-miR-29b-2/c clusters expressionin bone marrow (BM)was measured by quantitative reverse transcription polymerase chain reaction & normalized to 18S. The median normalized gene expression defined high & low pre-miR-29a/b-1 & pre-miR-29b-2/c clusterexpressers. Median follow-up was 4.4y for pts alive. At diagnosis a high pre-miR-29a/b-1 expression did not associate with clinical characteristics. High pre-miR-29a/b-1 expressers were less likely to be TP53 mut (p=.01). Pts with high pre-miR-29b-2/c expression at diagnosis had higher BM blast counts (p=.01), were more likely to have a normal cytogenetics (CN, p=.03) & were less likely to be TP53 (p=.004) or ASXL1 mutated (p=.03). When we combined the expression status information of the two miR-29 clusters we found that AML blasts of pts with high expression of both clusters were less likely to be CD34 (p=.05) or CD117 (p=.04) positive & more likely to be CD11b positive (p=.05). These pts more often had CN-AML (p=.04) & better ELN genetic risk (p=.03). High expressers of both miR-29 clusters were also more likely to be DNMT3A mut (p=.01) & less likely to be EVI1 positive (p=.007). Noteworthy, none of the pts with high expression of both clusters had a TP53 (p=.16) or ASXL1 mutation (p=.08). Pts with a high expression of both miR-29 clustershad a significant longer relapse free survival (RFS, p=.01, Figure 1a) & overall survival (OS, p=.03) compared to pts with low expression of one or both miR-29 clusters. In conclusion, high expression of pre-miR-29a/b-1 & pre-miR-29b-2/c associated with different clinical & genetic characteristic at AML diagnosis. High expressers of both clusters were more often DNMT3A mutated, a gene targeted by miR-29. Furthermore, none of these patients harbored TP53 mutations, a gene known to be indirectly activated by miR-29 family members. These findings provide new insights into the miR-29 associated AML biology, which may contribute to the observed impact on AML pts outcomes. While we observed a trend for better survival for each miR-29 cluster, pts with high expression of the pre-miR-29a/b-1 & the pre-miR-29b-2/c clusterhad significantly longer RFS & OS.

(Na0.5Bi0.5)TiO3 (Abbreviated to BNT) was synthesized by hydrothermal process and the average gain size was 15 nm with narrow size distribution. Pure perovskite structure of BNT particles was identified by XRD analysis. The nanoscale BNT powder was selected as raw material to fabricate BNT based ceramics with BaTiO3 (Abbreviated to BT) and Ba(Cu0.5W0.5)O3 (Abbreviated to BCW) doping. SEM images show that the ceramic using nanoscale BNT powder as raw material has a high dense body with the average gain size from 0.5 μm to 1 μm. The experimental results show that with increasing amount of BCW, d33 and Kp of (0.94-x)BNT-0.06BT-xBCW increase initially, then reach the maximum values of 130 pC/N and 0.32 when 5mol% of BCW was added. Further increasing amount of BCW leads to decreasing d33 and Kp. The optimal piezoelectric and dielectric properties were obtained as d33 = 130 pC/N, Kp = 0.32, εr = 800, tgδ = 0.06.

The family Phasmatidae Gray, 1835 is reviewed and the subfamily Phasmatinae shown to be polyphyletic. Based on features of the exosceleton of the insects, egg-morphology and copulation habits a new arrangement of Phasmatidae is proposed. The monophyly of Lanceocercata Bradler, 2001 is confirmed but this name shown to be a synonym of Phasmatidae, hence Lanceocercata is here referred to as Phasmatidae sensu stricto. Six subfamilies belong in Phasmatidae sensu stricto all of which share several common and supposedly apomorphic characters: Phasmatinae, Tropidoderinae, Extatosomatinae (stat. nov.), Xeroderinae, Pachymorphinae and “Platycraninae”. The other two subfamilies contained in Phasmatidae sensu Bradley & Galil, 1977 (Eurycanthinae and Cladomorphinae) are not cosely related and here regarded as subfamilies of Phasmatidae sensu lato. The subfamily Phasmatinae sensu Bradley & Galil, 1977 is shown to be polyphyletic. The two tribes Pharnaciini and Clitumnini (= Baculini Günther, 1953) are removed from Phasmatinae and shown to be closely related to each other. They are transferred to the here established subfamily Clitumninae, a subordinate clade of Phasmatidae sensu lato. The subfamily Lonchodinae is closely related to Clitumninae, hence removed from Diapheromeridae and transferred to Phasmatidae sensu lato. The tribes Achriopterini and Stephanacridini (formerly in Phasmatinae) are shown to be not closely related to either Phasmatinae sensu stricto, Clitumninae or Lonchodinae, and provisionally must be treated as tribes of Phasmatidae sensu lato (incerte sedis). A re-arrangement of Phasmatidae sensu stricto is proposed along with determinating keys to all subfamilies and their tribes. The subfamilies Phasmatinae, Tropidoderinae and Extatosomatinae stat. nov. are re-described and discussed in detail. Full lists of genera are provided for each tribe. Only three of seven tribes formerly in Phasmatinae remain in the subfamily, this is Phasmatini, Acanthomimini and Acanthoxylini. The subfamily Tropidoderinae contains three tribes: Tropidoderini, Monandropterini and Gigantophasmatini trib. nov. The tribe Extatosomatini Clark-Sellick, 1997 is removed from Tropidoderinae and raised to subfamily level (Extatosomatinae stat. nov.). Several genera are transferred to other tribes or subfamilies. Didymuria Kirby, 1904 is removed from Tropidoderini, since it differs by having a closed internal micropylar plate in the eggs (open in all Tropidoderini). It here remains as a genus incerte sedis of Tropidoderinae and its systematic position clearly deserves further clarification. Gigantophasma Sharp, 1898 from the Loyalty Islands is removed from Pharnaciini, and becomes the type genus of the tribe Gigantophasmatini trib. nov.. Anophelepis Westwood, 1859 is removed from “Platycraninae” and shown to belong in Phasmatinae: Acanthomimini. The two Australian genera Arphax Stål, 1875, and Vasilissa Kirby, 1896 are removed from Acanthoxylini and provisionally transferred to Acanthomimini, but their position remains as yet debatable. Echetlus Stål, 1875 is misplaced in “Platycraninae” and shown to be a likely member of Phasmatinae. The two Brazilian species Echetlus evoneobertii Zompro & Adis, 2001 and Echetlus fulgens Zompro, 2004b are obviously misplaced and belong in the New World Diapheromeridae: Diapheromerinae: Diapheromerini. The subfamily Pachymorphinae is briefly discussed and considered polyphyletic. Two genera of Pachymorphinae: Gratidiini Bragg, 1995 (Parapachymorpha Brunner v. Wattenwyl, 1893 and Cnipsomorpha Hennemann et al., 2008) are transferred to Clitumninae: Medaurini trib. nov. The genus Gongylopus Brunner v. Wattenwyl, 1907 is transferred from Pachymorphinae: Gratidiini to Clitumninae: Clitumnini. The subfamily Xeroderinae is briefly discussed and shown likely to be polyphyletic, due to it contains two fundamentally different types of genitalia in the males. Only the genera Xeroderus Gray, 1835 and perhaps Epicharmus Stål, 1875 clearly belong in Phasmatidae sensu stricto. Both, the Pachymorphinae and Xeroderinae certainly deserve more detailed investigation to clarify their systematic positions with confirmation. Two generic groups are recognized within Clitumnini (subfamily Clitumninae). Due to differing by genital features and egg-morphology Medaura Stål, 1875 and Medauroidea Zompro, 2000 are removed from Clitumnini and transferred to the newly described Medaurini trib. nov.. The new tribe furthermore contains two genera formerly included in Pachymorphinae: Gratidiini and transferred here, Cnipsomorpha Hennemann et al., 2008 and Parapachymorpha Brunner v. Wattenwyl, 1893. Phryganistria Stål, 1875 is removed from Clitumnini and transferred to Pharnaciini. Nesiophasma Günther, 1934 is shown to belong in the tribe Stephanacridini. The Australasian subfamily Lonchodinae Brunner v. Wattenwyl, 1893 has formerly been included in Diapheromeridae Zompro, 2001 (= Heteronemiidae by Bradley & Galil, 1977). However, numerous features of the genitalia and egg morphology show close relation to the Oriental subfamily Clitumninae instead. Thus, Lonchodinae is here transferred to the family Phasmatidae (sensu lato). Within Lonchodinae the new tribe Neohiraseini trib. nov. is recognized and contains the five genera formerly placed in the “Neohirasea-complex” of that subfamily, namely Andropromachus Carl, 1913, Neohirasea Rehn, 1904, Pseudocentema Chen, He & Li, 2002, Qiongphasma Chen, He & Li, 2002 and Spinohirasea Zompro, 2001. It differs from all other Lonchodinae (= tribe Lonchodini) by the well developed vomer of males and the lack of a capitulum in the eggs. The genus Cladomimus Carl, 1915 was previously misplaced in Clitumninae: Pharnaciini and is here transferred to Lonchodinae: Lonchodini. It appears to be close to the Australian Hyrtacus Stål, 1875. Leprocaulinus Uvarov, 1940 and Phenacocephalus Werner, 1930 are removed from the subfamily Necrosciinae and transferred to Lonchodinae: Lonchodini. Extensive research on the genera which belong to the tribe Pharnaciini Günther, 1953 and taking features of the genital exosceleton and egg-morphology into account, has shown this tribe to be polyphyletic. Based on such features two generic groups are easily recognized within Pharnaciini sensu Günther, 1953. Males of the first group have a longitudinally split anal segment, which consists of two separate, more or less elongate semi-tergites and forms a clasping apparatus, the vomer is strongly reduced or lacking, the profemora have a prominent, lamellate medioventral carina which is strongly displaced towards the anteroventral carina and the eggs have an open internal micropylar plate with a clear median line. Only the genera falling into this group remain in Pharnaciini. Males of the second group in contrast have an anal segment which is not split, but possess a clearly visible, well sclerotised, triangular or hook-like external vomer, an indistinct medioventral carina on the profemora and eggs with a closed internal micropylar plate. Most of the genera which fall into the second group are here transferred to the tribe Stephanacridini Günther, 1953, this is Diagoras Stål, 1877b, Eucarcharus Brunner v. Wattenwyl, 1907, Phasmotaenia Návas, 1907 and Sadyattes Stål, 1875. A detailed discussion of the differences between Pharnaciini and Stephanacridini is provided along with distinguishing keys, illustrations and maps showing the distinct geographic distributions. The five genera that belong in Pharnaciini are: Baculonistria gen. nov., Pharnacia Stål, 1877a, Phobaeticus Brunner v. Wattenwyl, 1907 (= Baculolonga Hennemann & Conle, 1997a, = Lobophasma Günther, 1934b syn. nov. , = Nearchus Redtenbacher, 1908 syn. nov. ), Tirachoidea Brunner v. Wattenwyl, 1893 stat. rev. and Phryganistria Stål, 1875. Pharnacia annulata Redtenbacher, 1908 and Pharnacia enganensis Redtenbacher, 1908 were misplaced in Pharnacia Stål, 1877 (tribe Pharnaciini) and are transferred to the genus Sadyattes Stål, 1875 (tribe Stephanacridini, comb. nov.). Phobaeticus kuehni Brunner v. Wattenwyl, 1907 is removed from Phobaeticus Brunner v. Wattenwyl, 1907 (Phasmatinae: Pharnaciini) and shown to belong in Nesiophasma Günther, 1934c (tribe Stephanacridini, comb. nov.). Phobaeticus incertus Brunner v. Wattenwyl, 1907 (= Nearchus grubaueri Redtenbacher, 1908 syn. nov.) is unlikely to belong in Pharnaciini and here only retained in the original genus Phobaeticus Brunner v. Wattenwyl, 1907 with doubt, it may belong in Nesiophasma Günther, 1934c (tribe Stephanacridini). Based on a total of almost 700 examined specimens, the Oriental tribe Pharnaciini Günther, 1953 is revised at the species level. The new genus Baculonistria gen. nov. (Type species Baculonistria alba (Chen & He, 1990) comb. nov.), is described to contain three species from Central and Eastern China. Tirachoidea Brunner v. Wattenwyl, 1893 was erroneously synonymised with Pharnacia Stål, 1877 and is here re-established as a valid genus (stat. rev.). All five genera are re-diagnosed and differentiated, their systematic position within Pharnaciini discussed, and complete synonymic and species-listings as well as distribution maps and determination keys to the insects and eggs are provided. Detailed descriptions, diagnoses, synonymic listings, illustrations, material listings, distribution maps and measurements are provided for all 42 valid species. The type material of a further two species appears to be lost. Seven new species are described: Pharnacia borneensis spec. nov. from Borneo; Pharnacia palawanica spec. nov. from Palawan, Phobaeticus mucrospinosus spec. nov. from Sumatra, Phobaeticus palawanensis spec. nov. from Palawan, Tirachoidea herberti spec. nov. from Borneo, Tirachoidea siamensis spec. nov. from Thailand and S-Vietnam and Phobaeticus chani Bragg spec. nov. from Borneo. Phobaeticus chani Bragg spec. nov. is the world’s longest known insect with a maximum body length of 357 mm and an overall length of 567 mm in the female. Twelve new synonymies were discovered: Bactridium grande Rehn, 1920 = Phobaeticus serratipes (Gray, 1835) syn. nov.; Pharnacia rigida Redtenbacher, 1908 = Phobaeticus sumatranus Brunner v. Wattenwyl, 1907, syn. nov.; Clitumnus irregularis Brunner v. Wattenwyl, 1907 = Phibalosoma tirachus Westwood, 1859, syn. nov.; Pharnacia magdiwang Lit & Eusebio, 2008 = Pharnacia ponderosa Stål, 1877 syn. nov.; Pharnacia spectabilis Redtenbacher, 1908 = Phibalosoma hypharpax Westwood, 1859, syn. nov.; Pharnacia semilunaris Redtenbacher, 1908 = Eucarcharus inversus Brunner v. Wattenwyl, 1907, syn. nov.; Pharnacia chiniensis Seow-Choen, 1998c = Pharnacia biceps Redtenbacher, 1908, syn. nov.; Nearchus grubaueri Redtenbacher, 1908 = Phobaeticus incertus Brunner v. Wattenwyl, 1907, syn. nov.; Phibalosoma maximum Bates, 1865 = Cladoxerus serratipes Gray, 1835, syn. nov.; Phobaeticus lambirica Seow-Choen, 1998a = Eucarcharus rex Günther, 1928, syn. nov.; Phobaeticus sichuanensis Cai & Liu, 1993 = Baculum album Chen & He, 1990, syn. nov. and Phobaeticus beccarianus Brunner v. Wattenwyl, 1907 is shown to represent the previously unknown female of Phobaeticus sobrinus Brunner v. Wattenwyl, 1907 (syn. nov.) Lectotypes are designated for: Nearchus redtenbacheri Dohrn, 1910, Pharnacia biceps Redtenbacher, 1908, Pharnacia ingens Redtenbacher, 1908, Pharnacia heros Redtenbacher, 1908, Phibalosoma westwoodi Wood-Mason, 1875, Phobaeticus sinetyi Brunner v. Wattenwyl, 1907, and Phobaeticus sumatranus Brunner v. Wattenwyl, 1907. A neotype is designated for Nearchus maximus Redtenbacher, 1908 and Phobaeticus magnus nom. nov. introduced as a replacement name for Nearchus maximus Redtenbacher, which is a junior homonym of Phibalosoma maximum Bates, 1865.The previously unknown males of Pharnacia heros Redtenbacher, 1908, Phobaeticus ingens (Redtenbacher, 1908), Tirachoidea jianfenglingensis (Bi, 1994), Pharnacia sumatrana (Brunner v. Wattenwyl, 1907), Phryganistria fruhstorferi (Brunner v. Wattenwyl, 1907) and Tirachoidea westwoodii (Wood-Mason, 1875) as well as the females of Pharnacia ponderosa Stål, 1877a and Pharnacia tirachus (Westwood, 1859) are described and illustrated for the first time. A brief description on the basis of colour photos of the so far unknown male of Pharnacia kalag Zompro, 2005 are presented. Detailed descriptions and illustrations are provided for the eggs of 24 species. The eggs of the following 18 species are described and illustrated for the first time: Phobaeticus magnus nom. nov., Pharnacia borneensis spec. nov., Pharnacia palawanica spec. nov., Pharnacia ponderosa Stål, 1877a, Pharnacia sumatrana (Brunner v. Wattenwyl, 1907), Pharnacia tirachus (Westwood, 1859), Phobaeticus hypharpax (Westwood, 1859), Phobaeticus chani Bragg spec. nov., Phobaeticus incertus Brunner v. Wattenwyl, 1907, Phobaeticus magnus nom. nov., Phobaeticus philippinicus (Hennemann & Conle, 1997a), Phobaeticus sinetyi Brunner v. Wattenwyl, 1907, Phryganistria grandis Rehn, 1906, Phryganistria virgea (Westwood, 1848), Tirachoidea biceps (Redtenbacher, 1908), Tirachoidea herberti spec. nov., Tirachoidea jianfenglingensis (Bi, 1994) and Tirachoidea siamensis spec. nov.. Several species were originally placed in or subsequently transferred into wrong genera by various authors. Consequently, numerous taxa are here transferred or re-transferred to other genera, which results in 22 new or revised combinations or status of genera and species (comb. nov. / stat. rev. / stat. nov.). A list of the taxonomic changes made in this revision is provided in the summary ( 9.2), which in all lists 70 nomenclatural changes.

The aim of the study was to evaluated the effect of giving water hyacinth and fish oil in quail diet on the performance, egg cholesterol and egg fatty acid profile. This study used 200 unsex day old quail divided into 5 treatments and 4 replications that were reared 5 weeks and then selected male or female. The results of sexing quail at week 5 were 95 females and 86 males. Growth period diets (0-5 weeks) contains 24% crude protein and metabolic energy of 2900 kcal kg-1 and production period diets (5-12 weeks) contains 22% crude protein and 2900 kcal kg-1. The experimental design used a completely randomized design with the treatment of using water hyacinth that was 0%,1%, 2%, 3 % and 4% with fish oil which was 0%, 4%, 5%, 6% and 7% in quail diet. The variables measured were quail performance (0-5 week age and 5-12 week age), egg cholesterol, and egg fatty acid profile. The results showed that using of water hyacinth meal 1% -4% and fish oil 4%-5% in the diet of the growth period resulted in higher feed consumption and body weight gain than diet without water hyacinth and fish oil but feed conversion rasio were same. Quail performance of the production period was not affected by all treatments. Unsaturated fatty acids tend to increased in quail eggs. The lowest cholesterol level of quail eggs was by giving 2% of water hyacinth meal and 5% of fish oil in the diet. It was concluded that water hyacinth can be used as local feed ingredients in quail diet until 4%.

The aim of the study was to evaluated the effect of giving water hyacinth and fish oil in quail diet on the performance, egg cholesterol and egg fatty acid profile. This study used 200 unsex day old quail divided into 5 treatments and 4 replications that were reared 5 weeks and then selected male or female. The results of sexing quail at week 5 were 95 females and 86 males. Growth period diets (0-5 weeks) contains 24% crude protein and metabolic energy of 2900 kcal kg-1 and production period diets (5-12 weeks) contains 22% crude protein and 2900 kcal kg-1. The experimental design used a completely randomized design with the treatment of using water hyacinth that was 0%,1%, 2%, 3 % and 4% with fish oil which was 0%, 4%, 5%, 6% and 7% in quail diet. The variables measured were quail performance (0-5 week age and 5-12 week age), egg cholesterol, and egg fatty acid profile. The results showed that using of water hyacinth meal 1% -4% and fish oil 4%-5% in the diet of the growth period resulted in higher feed consumption and body weight gain than diet without water hyacinth and fish oil but feed conversion rasio were same. Quail performance of the production period was not affected by all treatments. Unsaturated fatty acids tend to increased in quail eggs. The lowest cholesterol level of quail eggs was by giving 2% of water hyacinth meal and 5% of fish oil in the diet. It was concluded that water hyacinth can be used as local feed ingredients in quail diet until 4%.

Finite element (FE) method is commonly used to study cracks in structures. In this paper, J-integral method is applied over FE model of a cracked body to determine stress intensity factor (SIF) in the domain of linear elastic fracture mechanics (LEFM). This paper formulates the J-integral methodology for 2D FE model using a coarse mesh with less degrees of freedom. Two cases , a finite plate with edge cracks and a normal crack growth in fiber metal laminated plate, are demonstrated. Numerical implementation and mesh refinement issues to maintain path independent J-integral values are explored.

Aim: The aim of this study is to find an optimum material to protect garment for protection against 99Tcm radionuclide.Materials and Methods: Monte Carlo simulation code was applied to investigate radiation attenuation of 13 shielding materials including: Ba, gray Sn, white Sn, Sb, Bi, Bi2O3, BaSO4, Sn/W, Sb/W, Pb and W with thicknesses of 0.5 and 1 mm to determine an optimum protective garment material in nuclear medicine against 99Tcm. Furthermore, the dose enhancement on the staff body was investigated for shielding materials such as tungsten and lead.Results: The findings of the simulations show that the maximum and minimum attenuation obtained with thicknesses of 1 mm W and 1 mm BaSO4 were 96.46% and 14.2%, respectively. The results also demonstrate that tungsten does not cause any dose enhancement on staff body but this is not true for lead. Tungsten provides the highest radiation attenuation without dose enhancement on the body of staff.Conclusion: Among materials evaluated, tungsten is the optimum material and it can be applied for the design of protective garment for nuclear medicine staff against 99Tcm.

In this study, an analytical method is presented for the computation of thermal weight functions in two dimensional bi-material elastic bodies containing a crack at the interface and subjected to thermal loads using body analogy method. The thermal weight functions are derived for two problems of infinite bonded dissimilar media, one with a semi-infinite crack and the other with a finite crack along the interface. The derived thermal weight functions are shown to reduce to the already known expressions of thermal weight functions available in the literature for the respective homogeneous elastic body. Using these thermal weight functions, the stress intensity factors are computed for the above interface crack problems when subjected to an instantaneous heat source.

This article presents the Hebrew translation of the introduction and the letter alef of the first Judaeo-Arabic Biblical dictionary extant, the Kitāb Jāmiʿ al-Alfāẓ, composed by the Karaite scholar David Ben Abraham al-Fāsī (fl. second half of the 10th century), ably edited by the late S.L. Skoss. The dictionary is quite comprehensive. Even if one does not take the introduction into consideration, the first volume contains no less than 600 pages, the second more than 750. The introduction itself deals intensively with various aspects of the structure of the dictionary. The main part of the dictionary is divided into 22 sections, reflecting the 22 letters of the Hebrew alphabet. Every section opens with an introduction characterizing the letter in question. The following main part is theoretically subdivided into 22 subsections, exhibiting the combination of the letter of the section dealt with, with one letter of Hebrew alphabet. Since, however, not every combination is attested, there are in fact, as a rule, less than 22 subsections. Every subsection is introduced by a list of the verses to be dealt with, followed by a thorough lexical and grammatical analysis, which forms the main body of the dictionary. Yet, the correspondence between the examples in the list and the analysis is not always clear. And one wonders what the real function of the list can be. The dictionary is based, in accordance with the period in which it was written, on the bi-radical and mono-radical system. There is no doubt that it is only the tri-radical principle that enables a clear and all-comprising analysis of the Hebrew roots. On the other hand, the bi-radical and mono-radical system does not artificially separate related weak roots. It was because of this relationship that Hebrew grammarians adhered to the bi-radical and mono-radical principle, and it was only through the influence of Arabic, in which the tri-radical structure of the verb is prominent that the tri-radical principle was adopted in Hebrew grammar. Being one of the first Judaeo-Arabic dictionaries, it is not surprising that the structure of subdivisions, containing lexical and grammatical analysis of the material, is sometimes ambiguous, at times because of the conciseness of expression. In the wake of Biblical prose, in which main clauses opening with copulative waw are very frequent, our dictionary tends to introduce main clauses with copulative waw, whereas classical Arabic utilizes fa in this environment. On the other hand, al-Fāsī frequently applies asyndetic clauses, both coordinated and subordinated ones. Like Judaeo-Arabic literature in general, our dictionary too is written in Middle Arabic, in which post-Classical Arabic, Neo-Arabic and also pseudo-corrections alternate. Sometimes al-Fāsī's Arabic is influenced by Hebrew, as when, in the wake of Hebrew hāyā, Arabic kāna governs its predicate with the preposition la. Sometimes the translation of Biblical verses is so literal as to be unintelligible; accordingly, al-Fāsī considers himself obliged to add another translation in a more comprehensible Arabic. On the other hand, al-Fāsī's understanding of Biblical Hebrew is often influenced by Arabic. Thus, when analyzing 'eshekh, he interprets it, as well as the verb shkhkh, by comparing the Hebrew verb shākhan (exhibiting shkh as the first part of its root), yet he attributes to it peculiar meanings of the parallel Arabic sakan, viz, 'to calm down' as well as its late signification ‘to be hidden'.

Formulation of the problem. Large size and great reserves, as well as the possibility to apply rational methods of metals extraction predetermined the increasing interest to the copper-porphyry deposits. Today, they are the main raw material based on Cu, Mo, accompanying metals all over the world. The value of these deposits lie in the fact that they are in located in geologically well-studied regions. However, their ores in basic and associated components have relatively small content of Cu, Mo, Au, Ag, Bi, Re, Se, Te, spreading in large area. The purpose of the article. The main objective of the research is to study distribution peculiarities of basic ore components of Goshgarchay deposits, to detect geochemical features and behaviour of elements in the process of sedimentation by developing geochemical criteria of the search and the prognosis of hidden mineralization. Methods. The author studied the distribution problem of basic ore components of copper-porphyry mineralization, carried out field investigations (field researches), documented and tested underground mine working and core samples of over seventy well bores. When choosing the type of analysis, a special attention was paid to the sensitivity and exactness of the determination method. Analytical work was conducted according to the definition of chemical elements. The following types of analytical methods were used: chemical, atomic-absorption, spectral-chemical, etc. The analytical data were processed by the method of mathematical statistics. Results. As follows from the analysis of the above-mentioned results, the elements flaccid for hydrothermal solutions (Cr, Ni, V, Co, Mn, Ti) keep their independence in all groups of rocks. Their grouping is probably associated with the process of crystallized differentiation of magma. The elements Cu, Pb, Zn, Ag and partly Mo, don’t have specific place. Their presence is likely associated with the degree of rocks susceptibility, hydrothermal interaction being the source of these elements. In various types of ores and mineral associations the definition of elemental impurities is different. Their amount increases the amount (quantity) of clarke and coefficient of concentration a thousand times. Three different mineral associations coexist in the ore body: 1-primary sulphide-chalcopyrite and bornite-chalcopyrite ore. 2-oxidized ore and zone of secondary enrichment. 3-primary sulphide ore, significantly enriched in copper. Scientific novelty. Based on existing analytical data, the author studied distribution of basic ore and admixture components (gangue) and basic sulphide minerals. The concentration in series of elemental impurities were detailed in ore-bearing rocks of copper-porphyry deposits of Goshgarchay. The primary geochemical zonality was revealed in the distribution of basic ore-containing components in the ore body of copper-porphyry deposits of Goshgarchay ore field. Practical significance. The revealed peculiarities of the distribution of basic ore components in the ore body and host rocks (wallrock), the factors contributing to the accumulation of indicated elemental impurities can be used as geochemical criteria for the prognosis of copper-porphyry mineralization , supporting the effective directions of the research.

Abstract Introduction The aim of this analysis was to investigate whether the standardized uptake value (SUV) normalized by lean body mass (SUL) is a more appropriate quantitative parameter compared to the commonly used SUV normalized by patient’s weight in 68Ga-PSMA11 PET/CT. Material and methods 68Ga-PSMA11 PET/CT scans of 121 patients with prostate cancer from two institutions were evaluated. Liver SUV was measured within a 3-cm volume-of-interest (VOI) in the right hepatic lobe and corrected for lean body mass using the Janmahasatian formula. SUV and SUL repeatability between baseline and follow-up scans of the same patients were assessed. Results SUV was significantly positively correlated with body weight (r = 0.35, p = 0.02). In contrast, SUL was not correlated with body weight (r = 0.23, p = 0.07). No significant differences were found between baseline and follow-up scan (p = 0.52). Conclusion The Janmahasatian formula annuls the positive correlations between SUV and body weight, suggesting that SUL is preferable to SUV for quantitative analyses of 68Ga-PSMA11 PET/CT scans.

Introduction‘Dream’ has been researched across numerous fields in its multiplicity within both a physical and emotional capacity. For Pagel et al., there is no fixed definition of what ‘dream’ is or are. However, in an advertising context, ’dream’ is the idealised version of our desires, re-visualised in real life (Coombes and Batchelor 103). It could be said that for countless consumers, advertising imagery has elicited dreams of living the perfect life and procuring material pleasures (Manca et al.; Hood). Goodis asserts, “advertising doesn’t always mirror how people are acting but how they are dreaming, in a sense what we are doing is wrapping up your emotions and selling them back to you” (qtd. in Back and Quaade 65). One component of this notion of ‘dream’ in advertising is captured by wishful images of the face and body in their ‘perfect form’ presented in a field of other beauty ideals. For our purposes, ‘dream’ is a “philosophical concept” (Pagel et al. 14) by which dreams are a series of aspirations and desires that consumers internalise, while at the same time, find difficult to achieve. ‘Dream’, then, will be used to critically explore how the beauty and advertising industries collectively employ ethnic ambiguity in addition to other tactics and strategies to sell us dream-like visions of idealised beauty. Forever Dreaming: The Introduction of Ethnic AmbiguityWe can link dreams to beauty as both areas of analysis contain many cultural interpretations and can be deconstructed to reveal different meanings (Sontag). In many ways, beauty is another dream and Sontag notes that the concept of beauty is often linked to certain physical traits that an individual possesses. These physical traits are capitalised upon by product marketing by which Hood claims, aims to enhance one, or even more, of them. For example, lipstick is not marketed as simply as a mixture of wax and pigment but rather a way to “obtain beauty, find romance or gain confidence” (7). As a result, global beauty brands can find long term marketing success through meaningful product marketing. This long-term marketing success relies on influencing human behaviour and perceptions. As a result of meaningful marketing, consumers may find themselves driven to purchase implicit qualities in products advertised to reflect their dreams (Hood).Following the 1980s, this version of meaningful marketing has become a driving purpose for advertising agencies around the globe (Steel). Advertising agencies rely on deeper human insights, identifying latent desires to create a brief that must ultimately sell a dream (Steel). The ideal strategy needs to define something that will build brand loyalty and encourage consumers to have a symbiotic relationship connecting their dreams with the product being sold. As Hood argues, “advertising consists of selling not just things but also dreams”. While this concept is one that “some see as inherently damning”, it is also inherently necessary (7). We understand that people are emotional beings, investing in the artefacts they build, obtain or use with significance “beyond merely utilitarian” (7). For these reasons, beauty advertisers act as the purveyors of dreams in the form of physical perfection as an articulation of consumer’s own aspirations of beauty.These aspirations of dream beauty are a direct representation of our thoughts and feelings. As such, it should be noted that we as consumers are often encouraged to draw inspiration from imagery that is often times seen as ethnically ambiguous. “Ethnic ambiguity” is the absence of any one prominent ethnic or racial feature that is easily discernible to one specific group (Garcia 234; Harrison et al.). An example of this ethnic ambiguity can be seen in marketing campaigns by high end makeup artist and her eponymous range of cosmetics, Charlotte Tilbury. Most notably, in a 2015 launch for her “Makeup Wardrobe”, Tilbury’s makeup palettes boasted 10 aspirational ‘looks’ and personas that could be achieved simply through purchase. The images of women featured on a figurative ‘wheel of fortune’ digital display used to market products online. This digital ‘wheel of fortune’ comprised of ethnically ambiguous models against descriptive persona’s such as “The Dolce Vita” and “The Glamour Muse”. These kinds of digital marketing tools required consumers to make a decision based on what their dream ‘look’ is through an ethnically ambiguous lens and from here are guided to purchase their desired aesthetic. Like Charlotte Tilbury, the beauty industry has seen a growing body of cosmetic brands that employ ethnic ambiguity to sell dreams of homogenised beauty. We will see the ways in which modern day beauty brands, such as Kylie Jenner Cosmetics and Fenty Beauty have come to adopt ethnic ambiguity or embrace entire ethnic and racial groups in order to expand their consumer influence.Aspirational Ambiguity: Dreams of DisempowermentSince the early 2000s, beauty advertising has seen a prominent rise in the use of ethnically ambiguous models. Some see this as an effort to answer the global desire for diversity and inclusion. However, the notion that beauty standards transcend racial boundaries and is inclusive, is simply another form of appropriating and fetishising ethnicity (R. Sengupta). In many ways, these manufactured dream-like versions of beauty have evolved to reach wider markets, in the hope that consumers will be emboldened to both embrace their racial heritage, and at the same time conform to homogenised standards of beauty (Frith et al.; Harrison et al.).In this bid to diversify and extend consumer reach, there are three prominent reasons why ethnically ambiguous models are more likely to be featured over models whose African, Indigenous, and/or Asian heritage is more prominent. Firstly, ethnically ambiguous models do not seem to conform to a particular notion of what is considered beautiful. For many decades, popular culture has been saturated with images of thin, of young, of narrow noses and hips, of blonde, blue eyes, and Caucasian hair textures (Harrison et al.; Hunter; Saraswati). These Westernised beauty ideals have been historically shaped through years of colonial influence, grounded in an imbalance of power and imposed to create a culture of dominance and oppression (Saraswati). Secondly, ethnic models are featured to convey “the sense of the ‘exotic’, and their ‘otherness’ acts to normalise and entrench the dominant ideal of white beauty” (qtd. in Redmond 175). ‘Otherness’ can be defined as the opposite of the majority, in Westernised society this ‘other’ can mean “people who are other than white, male, able bodied, heterosexual” (qtd. in Graycar 74). This ‘otherness’ showcased by ethnically ambiguous models draws viewers in. Physical features that were possessed by one specific ethnic group such as African, Asian, Latinx or Indigenous peoples have now become blended and are no longer confined to one race. Additionally, ethnically ambiguous models enable white consumers to dream about an exotic local or lifestyle, while at the same time providing ethnic audiences a way to see themselves.Finally, it is undeniable that ethnically ambiguous and mixed-race models have become desirable due to a historical preference for light skin (Saraswati). The visual references of light-skinned beauty epitomise a colonial dream and this standardisation has been transferred to indigenous peoples, or ethnic minorities in Western countries. According to Harrison et al, “marketers use mixed-race representations as cultural currency by mythologising mixed-race bodies as the new beauty standard” to represent a racial bridge, “tailored to ameliorate perceived racial divides” (503). Therefore, ethnically ambiguous models have an assumed advantage over their racially dominant counterparts, because they appear to straddle various racial boundaries. They are constructed to embody whomever, from wherever and whenever, fetishising their roleplay for the industry, when it pleases. This further exoticises multi-racial beauty models and renders them a commodified fantasy for many consumers alike. The continued commodification of ethnic ambiguity is problematic as it exploits models with distinctly mixed-race heritage to continue to sell images of white-washed beauty (Solomon et al.). An argument could be made that scarcity contributes to mixed-race models’ value, and therefore the total number of advertising opportunities that are offered to mixed-race models remains limited. To date, numerous studies highlight a limited use of racially diverse models within the beauty industry and does not reflect the growing global body of diverse consumers with purchasing power (Wasylkiw et al.; Redmond; Johnson; Jung and Lee; Frith et al.). In fact, prior to globalisation, Yan and Bissell claim that “each culture had a unique standard of attractiveness, derived from traditional views about beauty as well as the physical features of the people” (197) and over time the construction of dream beauty is characterised using Western features combined with exoticised traits of indigenous ethnic groups. Akinro and Mbunyuza-Memani claim that this “trend of normalising white or 'western' feminine looks as the standard of beauty” has pervaded a number of these indigenous cultures, eventually disseminated through the media as the ultimate goal (308). It can also be argued that the “growing inclusion of mixed-race models in ads is driven less by the motivation to portray diversity and driven more by pragmatism,” and in a more practical sense has implications for the “financial future of the advertised brands and the advertising industry as a whole” (Harrison et al. 513). As a result, uses of mixed-race models “are rather understood as palatable responses within dominant white culture to racial and ethnic minority populations growing in … cultural prominence” (513) in a tokenistic bid to sell a dream of unified beauty.The Dream Girl: Normalisation of Mixed-RaceIn 2017, an article in CNN’s Style section highlighted the growing number of mixed-race models in Japan’s fashion and beauty industry as a modern-day phenomenon from Japan’s interlocking history with the United States (Chung and Ogura). These beauty and fashion influencers refer to themselves as hafu, an exclusionary term that historically represented an “othered” minority of mixed-race heritage in Japanese society signalling complex and troubled interactions with majority Japanese (Oshima). The complications once associated with the term ‘hafu’ are now being reclaimed by bi-racial beauty and fashion models and as such, these models are beginning to defy categorisation and, in some ways, national identity because of their chameleon-like qualities. However, while there is an increasing use of mixed-race Japanese models, everyday mixed-race women are regularly excluded within general society; which highlights the incongruent nature of ‘half’ identity. And yet there is an increasing preference and demand from fashion and beauty outlets to feature them in Japanese and Western popular culture (Harrison et al.; Chung and Ogura). Numéro Tokyo’s editorial director Sayumi Gunji, estimated that almost 30-40 per cent of runway models in present day Japan, identify as either bi-racial mixed-race or multi-racial (Chung and Ogura).Gunji claims:"Almost all top models in the their 20s are hafu, especially the top models of popular fashion magazines ... . [In] the Japanese media and market, a foreigner's flawless looks aren't as readily accepted -- they feel a little distant. But biracial models, who are taller, have bigger eyes, higher noses [and] Barbie-doll-like looks, are admired because they are dreamy looking but not totally different from the Japanese. That's the key to their popularity," she adds. (Qtd. in Chung and Ogura)The "dreamy look" that Gunji describes is attributed to a historical preference toward light skin and a kind of willingness and sensuality, that once, only white models could be seen to tout (Frith et al. 58). Frith et al. and O’Barr discuss that beauty in Japanese advertising mirrors “the way women are portrayed in advertising in the West” (qtd. in Frith et al. 58). The emergence of hafu in Japanese beauty advertising sees these two worlds, a mixture of doll-like and sensual beauty, converging to create a dream-like standard for Japanese consumers. The growing presence of Japanese-American models such as Kiko Mizuhara and Jun Hasegawa are both a direct example of the unattainable ‘dreamy look’ that pervades the Japanese beauty industry. Given this ongoing trend of mixed-race models in beauty advertising, a recent article on Refinery29 talks about the significance of how mixed-race models are disassembling their once marginalised status.A. Sengupta writes:In contrast to passing, in which mixedness was marginalized and hidden, visibly multiracial models now feature prominently in affirmative sites of social norms. Multiracial looks are normalized, and, by extension, mixed identity is validated. There’s no cohesive social movement behind it, but it’s a quiet sea change that’s come with broadened beauty standards and the slow dismantling of social hierarchies.Another example of the normalisation in multi-racial identity is Adwoa Aboah, a mixed-race British model and feminist activist who has been featured on the covers of numerous fashion publications and on runways worldwide. In British Vogue’s December 2017 issue, titled “Great BRITAIN”, Adwoa Aboah achieved front cover status, alongside her image featured other politically powerful names, perhaps suggesting that Aboah represents not only the changing face of a historically white publication but as an embodiment of an increasingly diverse consumer landscape. Not only is she seen as both as a voice for those disenfranchised by the industry, by which she is employed, but as a symbol of new dreams. To conclude this section, it seems the evolution of advertising’s inclusion of multi-racial models reveals a progressive step change for the beauty industry. However, relying simply on the faces of ethnically ambiguous talent has become a covert way to fulfil consumer’s desire for diversity without wholly dismantling the destructive hierarchies of white dominance. Over this time however, new beauty creations have entered the market and with it two modern day icons.Architecting Black Beauty through the American DreamAccording to Kiick, the conception of the ‘American Dream’ is born out of a desire to “seek out a more advantageous existence than the current situation” (qtd. in Manca et al. 84). As a result of diligent hard work, Americans were rewarded with an opportunity for a better life (Manca et al.). Kylie Jenner’s entry into the beauty space seemed like a natural move for the then eighteen-year-old; it was a new-age representation of the ‘American Dream’ (Robehmed 2018). In less than five years, Jenner has created Kylie Cosmetics, a beauty empire that has since amassed a global consumer base, helping her earn billionaire status. A more critical investigation into Jenner’s performance however illustrates that her eponymous range of beauty products sells dreams which have been appropriated from black culture (Phelps). The term cultural appropriation refers to the way dominant cultures “adopt and adapt certain aspects of another’s culture and make it their own” (qtd. in Han 9). In Jenner’s case, her connection to ethnic Armenian roots through her sisters Kourtney, Kim, and Khloe Kardashian have significantly influenced her expression of ‘othered’ culture and moreover ethnic beauty ideals such as curvier body shapes and textured hair. Jenner’s beauty advertisements have epitomised what it means to be black in America, cherry picking racialised features of black women (namely their lips, hips/buttocks and afro-braided hairstyles) and rearticulated them through a white lens. The omission of the ‘black experience’ in her promotion of product is problematic for three reasons. Firstly, representing groups or people without invitation enables room for systemic stereotyping (Han). Secondly, this stereotyping can lead to continued marginalisation of minority cultures (Kulchyski). And finally, the over exaggeration of physical attributes, such as Jenner’s lips, hips and buttocks, reinforces her complicity in exoticising and fetishising the “other”. As a result, consumers of social media beauty advertising may pay less attention to cultural appropriation if they are already unaware that the beauty imagery they consume is based on the exploitation of black culture.Another perspective on Jenner’s use of black culture is in large part due to her cultural appreciation of black beauty. This meaning behind Jenner’s cultural appreciation can be attributed to the inherent value placed on another person’s culture, in the recognition of the positive qualities and the celebration of all aspects of that culture (Han). This is evidenced by her recent addition of cosmetic products for darker complexions (Brown). However, Jenner’s supposed fascination with black culture may be in large part due to the environment in which she was nurtured (Phelps). As Phelps reveals, “consider the cultural significance of the Kardashian family, and the various ways in which the Kardashian women, who are tremendously wealthy and present as white, have integrated elements of black culture as seemingly “natural” in their public bodily performances” (9). Although the Kardashian-Jenner family have faced public backlash for their collective appropriation they have acquired a tremendous “capital gain in terms of celebrity staying power and hyper-visibility” (Phelps 9). Despite the negative attention, Kylie Jenner’s expression of black culture has resurfaced the very issues that had once been historically deemed insignificant. In spite of Jenner’s cultural appropriation of black beauty, her promotion through Kylie Cosmetics continues to sell dreams of idealised beauty through the white lens.In comparison, Rihanna Fenty’s cosmetic empire has been touted as a celebration of diversity and inclusion for modern-age beauty. Unlike Kylie Cosmetics, Fenty’s eponymous brand has become popular for its broader message of inclusivity across both skin tone, body shape and gender. Upon her product release, Fenty Beauty acknowledged a growing body of diverse consumers and as a direct response to feature models of diverse skin tones, cultural background and racial heritage. Perhaps more importantly, Fenty Beauty’s challenge to the ongoing debate around diversity and inclusion has been in stark contrast to Kylie Jenner’s ongoing appropriation of black culture. Images featured at the first brand and product launch of Fenty Beauty and in present day advertising, show South Sudanese model Duckie Thot and hijab-wearing model Halima Aden as central characters within the Fenty narrative, illustrating that inclusion need not remain ambiguous and diversity need not be appropriated. Fenty’s initial product line up included ninety products, but most notably, the Pro Filt’r foundation caused the most publicity. Since its introduction in 2017, the foundation collection contained range of 40 (now 50) inclusive foundation shades, 13 of these shades were designed to cater for much darker complexions, an industry first (Walters). As a result of the brand’s inclusion of diverse product shades and models, Fenty Beauty has been shown to push boundaries within the beauty industry and the social media landscape (Walters). Capitalising on all races and expanding beauty ideals, Fenty’s showcase of beauty subscribes to the notion that for women everywhere in the world, their dreams can and do come true. In conclusion, Fenty Beauty has played a critical role in re-educating global consumers about diversity in beauty (Walters) but perhaps more importantly Rihanna, by definition, has become a true embodiment of the ‘American Dream’.Conclusion: Future Dreams in BeautyIt is undeniable that beauty advertising has remained complicit in selling unattainable dreams to consumers. In the context of ‘dream’ as a philosophical concept, it is more important than ever to ensure our dreams are mirrored, not as an ambiguous body of consumers, but as diverse and unique individuals. Changemakers in the industry such as Fenty Beauty are challenging this status quo and beauty advertising in general will have to evolve their strategy in a bid to answer to an increasingly globalised market. It must be reinforced however, that while “beauty companies and advertisers work effectively to reach a growingly multicultural market, scholars have a responsibility to assess the ramifications that accompany such change,” (Harrison et al. 518). If advertising’s role is to mirror consumers’ dreams then, our roles as dreamers have never been so important. ReferencesAkinro, Ngozi, and Lindani Mbunyuza-Memani.

Music from Another Time – One Perth Night in 2009The following extract is taken from fieldwork notes from research into the enduring Northern Soul dance scene in Perth, Western Australia.It’s 9.30 and I’m walking towards the Hyde Park Hotel on a warm May night. I stop to talk to Jenny, from London, who tells me about her 1970s trip to India and teenage visits to soul clubs in Soho. I enter a cavernous low-ceilinged hall, which used to be a jazz venue and will be a Dan Murphy’s bottle shop before the year ends. South West Soul organiser Tommy, wearing 34-inch baggy trousers, gives me a Northern Soul handshake, involving upturned thumbs. ‘Spread the Faith’, he says. Drinkers are lined up along the long bar to the right and I grab a glass of iced water. A few dancers are out on the wooden floor and a mirror ball rotates overhead. Pat Fisher, the main Perth scene organiser, is away working in Monaco, but the usual suspects are there: Carlisle Derek, Ivan from Cheltenham, Ron and Gracie from Derby. Danny is back from DJing in Tuscany, after a few days in Widnes with old friends. We chat briefly mouth to ear, as the swirling strings and echo-drenched vocals of the Seven Souls’ 45 record, ‘I still love you’ boom through the sound system. The drinkers at the bar hit the floor for Curtis Mayfield’s ‘Move on up’ and the crowd swells to about 80. When I move onto the floor, Barbara Acklin’s ‘Am I the Same Girl?’ plays, prompting reflection on being the same, older person dancing to a record from my teenage years. On the bridge of the piano and conga driven ‘’Cause you’re mine’, by the Vibrations, everybody claps in unison, some above their heads, some behind their backs, some with an expansive, open-armed gesture. The sound is like the crack of pistol. We are all living in the moment, lost in the music, moving forward and backward, gliding sideways, and some of us spinning, dervish-like, for a few seconds, if we can still maintain our balance.Having relocated their scene from England south to the Antipodes, most of the participants described on this night are now in their sixties. Part of the original scene myself, I was a participant observer, dancing and interviewing, and documenting and exploring scene practices over five years.The local Perth scene, which started in 1996, is still going strong, part of a wider Australian and New Zealand scene. The global scene goes back nearly 50 years to the late 1960s. Northern Soul has now also become southern. It has also become significantly present in the USA, its place of inspiration, and in such disparate places as Medellin, in Colombia, and Kobe, in Japan.The feeling of ‘living in the moment’ described is a common feature of dance-oriented subcultures. It enables escape from routines, stretches the present opportunity for leisure and postpones the return to other responsibilities. The music and familiar dance steps of a long-standing scene like Northern Soul also stimulate a nostalgic reverie, in which you can persuade yourself you are 18 again.Dance steps are forward, backward and sideways and on crowded dancefloors self-expression is necessarily attenuated. These movements are repeated and varied as each bar returns to the first beat and in subcultures like Northern Soul are sufficiently stylised as to show solidarity. This solidarity is enhanced by a unison handclap, triggered by cues in some records. Northern Soul is not line-dancing. Dancers develop their own moves.Place of Origin: Soul from the North?For those new to Northern Soul, the northern connection may seem a little puzzling. The North of England is often still imagined as a cold, rainy wasteland of desolate moors and smoky, industrial, mostly working-class cities, but such stereotyping obscures real understanding. Social histories have also tended to focus on such phenomena as the early twentieth century Salford gang members, the “Northern Scuttlers”, with “bell-bottomed trousers … and the thick iron-shod clogs” (Roberts 123).The 1977 Granada television documentary about the key Northern Soul club, Wigan Casino, This England, captured rare footage; but this was framed by hackneyed backdrops of mills and collieries. Yet, some elements of the northern stereotype are grounded in reality.Engels’s portrayal of the horrors of early nineteenth century Manchester in The Condition of the Working Class in England in 1844 was an influential exploration of the birth pains of this first industrial city, and many northern towns and cities have experienced similar traumas. Levels of social disadvantage in contemporary Britain, whilst palpable everywhere, are still particularly significant in the North, as researched by Buchan, Kontopantelis, Sperrin, Chandola and Doran in North-South Disparities in English Mortality 1965–2015: Longitudinal Population Study.By the end of the 1960s, the relative affluence of Harold Wilson’s England began to recede and there was increased political and counter-cultural activity. Into this social climate emerged both skinheads, as described by Fowler in Skins Rule and the Northern Soul scene.Northern Soul scene essentially developed as an extension of the 1960s ‘mod’ lifestyle, built around soul music and fashion. A mostly working-class response to urban life and routine, it also evidenced the ability of the more socially mobile young to get out and stay up late.Although more London mods moved into psychedelia and underground music, many soul fans sought out obscure, but still prototypical Motown-like records, often from the northern American cities Detroit and Chicago. In Manchester, surplus American records were transported up the Ship Canal to Trafford Park, the port zone (Ritson and Russell 1) and became cult club hits, as described in Rylatt and Scott’s Central 1179: The Story of Manchester's Twisted Wheel.In the early 1970s, the rare soul fans found a name for their scene. “The Dave Godin Column” in the fanzine Blues and Soul, published in London, referred for the first time to ‘Northern Soul’ in 1971, really defining ‘Northern’ directionally, as a relative location anywhere ‘north of Watford’, not a specific place.The scene gradually developed specific sites, clothes, dances and cultural practices, and was also popular in southern England, and actually less visible in cities such as Liverpool and Newcastle. As Nowell (199) argues, the idea that Northern Soul was regionally based is unfounded, a wider movement emerging as a result of the increased mobility made possible by railways and motorways (Ritson and Russell 14).Clubs like the Blackpool Mecca and Wigan Casino were very close to motorway slip roads and accessible to visitors from further south. The initial scene was not self-consciously northern and many early clubs, like the ‘Golden Torch’, in Tunstall were based in the Midlands, as recounted by Wall (441).The Time and Space of the DancefloorThe Northern Soul scene’s growth was initially covered in fanzines like Blues and Soul, and then by Frith and Cummings (23-32). Following Cosgrove (38-41) and Chambers (142), a number of insider accounts (Soul Survivors: The Wigan Casino Story by Winstanley and Nowell; Too Darn Soulful: The Story of Northern Soul by Nowell; The In-Crowd: The Story of the Northern & Rare Soul Scene by Ritson & Russell) were followed by academic studies (Milestone 134-149; Hollows and Milestone 83-103; Wall 431-445). The scene was first explored by an American academic in Browne’s Identity Scene and Material Culture: The Place of African American Rare Soul Music on the British Northern Soul Scene.Many clubs in earlier days were alcohol-free, though many club-goers substituted amphetamines (Wilson 1-5) as a result, but across the modern scene, drug-taking is not significant. On Northern Soul nights, dancing is the main activity and drinking is incidental. However, dance has received less subtle attention than it deserves as a key nexus between the culture of the scene and black America.Pruter (187) referred to the earlier, pre-disco “myopia” of many music writers on the subject of dance, though its connection to leisure, pleasure, the body and “serious self-realization” (Chambers 7) has been noted. Clearly Northern Soul dancers find “evasive” pleasure (Fiske 127) and “jouissance” (Barthes v) in the merging of self into record.Wall (440) has been more nuanced in his perceptions of the particular “physical geography” of the Northern Soul dance floor, seeing it as both responsive to the music, and a vehicle for navigating social and individual space. Dancers respond to each other, give others room to move and are also connected to those who stand and watch. Although friends often dance close, they are careful not to exclude others and dancing between couples is rare. At the end of popular records, there is often applause. Some dance all night, with a few breaks; others ‘pace’ themselves (Mercieca et al. 78).The gymnastics of Northern Soul have attracted attention, but the forward dives, back drops and spins are now less common. Two less noticed markers of the Northern Soul dancing style, the glide and the soul clap, were highlighted by Wall (432). Cosgrove (38) also noted the sideways glide characteristic of long-time insiders and particularly well deployed by female dancers.Significantly, friction-reducing talcum powder is almost sacramentally sprinkled on the floor, assisting dancers to glide more effectively. This fluid feature of the dancing makes the scene more attractive to those whose forms of expression are less overtly masculine.Sprung wooden floors are preferred and drink on the floor is frowned upon, as spillage compromises gliding. The soul clap is a communal clap, usually executed at key points in a record. Sometimes very loud, this perfectly timed unison clap is a remarkable, though mostly unselfconscious, display of group co-ordination, solidarity and resonance.Billy from Manchester, one of the Perth regulars, and notable for his downward clapping motion, explained simply that the claps go “where the breaks are” (Mercieca et al. 71). The Northern Soul clap demonstrates key attributes of what Wunderlich (384) described as “place-temporality in urban space”, emerging from the flow of music and movement in a heightened form of synchronisation and marked by the “vivid sense of time” (385) produced by emotional and social involvement.Crucially, as Morris noted, A Sense of Space is needed to have a sense of time and dancers may spin and return via the beat of the music to the same spot. For Northern Soul dancers, the movements forwards, backwards, sideways through objective, “geometric space” are paralleled by a traversing of existential, “conceived space”. The steps in microcosm symbolise the relentless wider movements we make through life. For Lefebvre, in The Production of Space, these “trialectics” create “lived space”.A Sense of Place and Evolving IdentitySpaces are plastic environments, charged with emerging meanings. For Augé, they can also remain spaces or be manipulated into “Non-Places”. When the sense of space is heightened there is the potential for lived spaces to become places. The space/place distinction is a matter of contention, but, broadly, space is universal and non-relational, and place is particular and relational.For Augé, a space can be social, but if it lacks implicit, shared cultural understandings and requires explicit signs and rules, as with an airport or supermarket, it is a non-place. It is not relational. It lacks history. Time cannot be stretched or temporarily suspended. As non-places proliferate, urban people spend more time alone in crowds, ”always, and never, at home” (109), though this anonymity can still provide the possibility of changing identity and widening experience.Northern Soul as a culture in the abstract, is a space, but one with distinct practices which tend towards the creation of places and identities. Perth’s Hyde Park Hotel is a place with a function space at the back. This empty hall, on the night described in the opening, temporarily became a Northern Soul Club. The dance floor was empty as the night began, but gradually became not just a space, but a place. To step onto a mostly empty dance floor early in the night, is to cross liminal space, and to take a risk that you will be conspicuous or lonely for a while, or both.This negotiation of space is what Northern Soul, like many other club cultures has always offered, the promise and risk of excitement outside the home. Even when the floor is busy, it is still possible to feel alone in a crowd, but at some stage in the night, there is also the possibility, via some moment of resonance, that a feeling of connection with others will develop. This is a familiar teenage theme, a need to escape bonds and make new ones, to be both mobile and stable. Northern Soul is one of the many third spaces/places (Soja 137) which can create opportunities to navigate time, space and place, and to find a new sense of direction and identity. Nicky from Cornwall, who arrived in Perth in the early 1970s, felt like “a fish out of water”, until involvement in the Northern Soul scene helped him to achieve a successful migration (Mercieca et al. 34-38). Figure 1: A Perth Northern Soul night in 2007. Note the talcum powder on the DJ table, for sprinkling on the dancefloor. The record playing is ‘Helpless’, by Kim Weston.McRobbie has argued in Dance and Social Fantasy that Northern Soul provides places for women to define and express themselves, and it has appealed to more to female and LGBTQIA participants than the more masculine dominated rock, funk and hip-hop scenes. The shared appreciation of records and the possibilities for expression and sociality in dance unite participants and blur gender lines.While the more athletic dancers have tended to be male, dancing is essentially non-contact, as in many other post-1960s ‘discotheque’ styles, yet there is little overt sexual display or flirtation involved. Male and female styles, based on foot rather than arm movements, are similar, almost ungendered, and the Soul scene has differed from more mainstream nightlife cultures focussed on finding partners, as noted in Soul Survivors: The Wigan Casino Story by Winstanley and Nowell. Whilst males, who are also involved in record buying, predominated in the early scene, women now often dominate the dance floor (Wall 441).The Perth scene is little different, yet the changed gender balance has not produced more partner-seeking for either the older participants, who are mostly in long-term relationships and the newer, younger members, who enjoy the relative gender-blindness, and focus on communality and cultural affinity. Figure 2: A younger scene member, ‘Nash’, DJing in Perth in 2016. He has since headed north to Denmark and is now part of the Nordic Northern Soul scene.In Perth, for Stan from Derby, Northern Soul linked the experiences of “poor white working class kids” with young black Americans (Mercieca et al. 97). Hollows and Milestone (87-94) mapped a cultural geographic relationship between Northern Soul and the Northern cities of the USA where the music originated. However, Wall (442) suggested that Northern Soul is drawn from the more bi-racial soul of the mid-1960s than the funky, Afro-centric 1970s and essentially deploys the content of the music to create an alternative British identity, rather than to align more closely with the American movement for self-determination. Essentially, Northern Soul shows how “the meanings of one culture can be transformed in the cultural practices of another time and place” (Wall 444).Many contemporary Australian youth cultures are more socially and ethnically mixed than the Northern Soul scene. However, over the years, the greater participation of women, and of younger and newer members, has made its practices less exclusive, and the notion of an “in-crowd” more relaxed (Wall 439). The ‘Northern’ connection is less meaningful, as members have a more adaptable sense of cultural identity, linked to a global scene made possible by the internet and migration. In Australia, attachment seems stronger to locality rather than nation or region, to place of birth in Britain and place of residence in Perth, two places which represent ‘home’. Northern Soul appears to work well for all members because it provides both continuity and change. As Mercieca et al. suggested of the scene (71) “there is potential for new meanings to continue to emerge”.ConclusionThe elements of expression and directional manoeuvres of Northern Soul dancing, symbolise the individual and social negotiation of direction, place, space, identity and time. The sense of time and space travelled can create a feeling of being pushed forward without control. It can also produce an emotional pull backwards, like an elastic band being stretched. For those growing older and moving far from places of birth, these dynamics can be particularly challenging. Membership of global subcultures can clearly help to create successful migrations, providing third spaces/places (Soja 137) between home and host culture identities, as evidenced by the ‘Southern’ Northern Soul scene in Australia. For these once teenagers, now grandparents in Australia, connections to time and space have been both transformed and transcended. They remain grounded in their youth, but have reduced the gravitational force of home connections, projecting themselves forward into the future by balancing aspects of both stability and mobility. Physical places and places and their connections with culture have been replaced by multiple and overlapping mappings, but it is important not to romanticise notions of agency, hybridity, third spaces and “deterritorialization” (Deleuze and Guattari in Anti-Oedipus: Capitalism and Schizophrenia). In a globalised world, most people are still located geographically and labelled ideologically. The Northern Soul repurposing of the culture indicates a transilience (Richmond 328) “differentially available to those in different locations in the field of power” (Gupta and Ferguson 20). However, the way in which Northern Soul has moved south over the decade via migration, has arguably now provided a stronger possible sense of resonance with the lives of black Americans whose lives in places like Chicago and Detroit in the 1960s, and their wonderful music, are grounded in the experience of family migrations in the opposite direction from the South to the North (Mercieca et al. 11). In such a celebration of “memory, loss, and nostalgia” (Gupta and Ferguson 13), it may still be possible to move beyond the exclusion that characterises defensive identities.ReferencesAugé, Marc.
