Full textAbstract:
This paper proposes a U-Model-Based Two-Degree-of-Freedom Internal Model Control (UTDF-IMC) structure with strength in nonlinear dynamic inversion, and separation of tracking design and robustness design. This approach can effectively accommodate modeling error and disturbance while removing those widely used linearization techniques for nonlinear plants/processes. To assure the expansion and applications, it analyses the key properties associated with the UTDF-IMC. For initial benchmark testing, computational experiments are conducted using MATLAB/Simulink for two mismatched linear and nonlinear plants. Further tests consider an industrial system, in which the IMC of a Permanent Magnet Synchronous Motor (PMSM) is simulated to demonstrate the effectiveness of the design procedure for potential industrial applications.

Full textAbstract:
Background Hyaluronan is one of the major extracellular matrixes in chronic rhinosinusitis (CRS) associated with tissue remodeling. Prostaglandin D2 (PGD2) is also associated with the pathogenesis of CRS. However, little is known about whether PGD2 regulates hyaluronan production by human airway fibroblasts. Objective We sought to determine the effect of PGD2 on the mRNA expression of three isoforms of membrane-bound hyaluronic acid synthase (HAS1, HAS2 and HAS3) in fibroblasts, the major source of hyaluronan production, derived from CRS patients. Methods Nasal polyp-derived fibroblasts (NPDF) and uncinate tissue-derived fibroblasts (UTDF) were established from CRS patients with nasal polyps and those without, respectively. These fibroblasts were stimulated with PGD2 or PGD2 receptor (DP/CRTH2)-selective agonists in the presence or absence of receptor-selective antagonists. mRNA levels for HAS1, HAS2 and HAS3 were determined by real-time quantitative PCR. Results PGD2 (1 µM) significantly enhanced HAS1 but not HAS2 or HAS3 mRNA expression by NPDF. Enhanced HAS1 mRNA expression was also obtained by stimulation with a DP receptor-selective agonist, but not with a CRTH2 receptor-selective agonist. In addition, PGD2-induced HAS1 mRNA expression was significantly inhibited by pre-treatment with DP receptor-selective antagonists. Similar induction of PGD2-induced HAS1 mRNA expression was seen in UTDF. Conclusion PGD2 selectively stimulates HAS1 mRNA expression in local fibroblasts in CRS via DP, but not CRTH2, receptors.

This article describes the design, implementation, and testing of a microcomputer package intended to improve students' understanding and skills in interpreting graphs of physical phenomena. In this package students interpret graphs in order to reproduce the events described by the graphs. Students may also construct events and challenge others to reproduce the events from the graphs they generate. Some previous work is described briefly to provide context for the activities. The package was used with students in grades nine through twelve. Students taking the college preparatory mathematics classes differed from those taking general mathematics in their choices of activities and in the strategies they used. There was evidence that students' strategies changed as they gained more experience.

Diagnostics 11, no. 8 (2021): 1472. http://dx.doi.org/10.3390/diagnostics11081472.
Full textAbstract:
Background: Ultrasonography’s usefulness in endometrial cancer (EC) diagnosis consists in its roles in staging and prediction of metastasis. Ultrasound-measured tumor-free distance from the tumor to the uterine serosa (uTFD) is a promising marker for these diagnostic and prognostic variables. The aim of the study was to determine the usefulness of this biomarker in locoregional staging, and thus in the prediction of lymph node metastasis (LNM). Methods: We conducted a single-institutional, prospective study on 116 consecutive patients with EC who underwent 2D transvaginal ultrasound examination. The uTFD marker was compared with the depth of ultrasound-measured myometrial invasion (uMI). Univariable and multivariable logit models were evaluated to assess the predictive power of the uTFD and uMI in regard to LNM. The reference standard was a final histopathology result. Survival was assessed by the Kaplan–Meier method. Results: LNM was found in 17% of the patients (20/116). In the univariable analysis, uMI and uTFD were significant predictors of LNM. The accuracy was 70.7%, and the NPV was 92.68% (OR 4.746, 95% CI 1.710–13.174) for uMI (p = 0.002), and they were 63.8% and 89.02% (OR 0.842, 95% CI 0.736–0.963), respectively, for uTFD (p = 0.01). The cutoff value for uTFD in the prediction of LNM was 5.2 mm. The association between absence of LNM and biomarker values of uMI < 1/2 and uTFD ≥ 5.2 mm was greater than that between the presence of metastases and uMI > 1/2 and uTFD values <5.2 mm. In the multivariable analysis, the accuracy of the uMI–uTFD model was 74%, and its NPV was 90.24% (p = non-significant). Neither uMI nor uTFD were surrogates for overall and recurrence-free survivals in endometrial cancer. Conclusions: Both uMI and uTFD, either alone or in combination, were valuable tools for gaining additional preoperative information on expected lymph node status. Negative lymph nodes status was better described by ultrasound biomarkers than a positive status. It was easier to use the uTFD rather than the uMI measurement as a biomarker of EC invasion, and the former still maintained a similar predictive value for lymph node metastases to the latter at diagnosis.

Full textAbstract:
Background This study was conducted to determine whether there is an association between urinary neutrophil gelatinase-associated lipocalin (uNGAL) and urinary transforming growth factor-β1 (uTGF-β1) with lupus nephritis (LN) disease activity. Methods Urine samples from 18 LN patients were collected every month for six months then examined for uNGAL, uTGF-β1, and renal domain Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score. Results The uNGAL levels were significantly different between active and inactive LN (P < 0.05). uTGF-β1 levels were not different between active and inactive LN (P > 0.05). There was a significant correlation between uNGAL levels and renal domain SLEDAI score (r= 0.417, P < 0.05). There was no correlation between uTGF-β1 levels and renal domain SLEDAI score (r = 0.031, P > 0.05). Conclusion uNGAL is better than uTGF-β1 for differentiation of active and inactive LN. uNGAL can be considered as a biomarker to monitor LN disease activity.

Full textAbstract:
Novel technologies to prevent biofilm formation on urinary tract devices (UTDs) are continually being developed, with the ultimate purpose of reducing the incidence of urinary infections. Probiotics have been described as having the ability to displace adhering uropathogens and inhibit microbial adhesion to UTD materials. This work aimed to evaluate the effect of pre-established Lactobacillus plantarum biofilms on the adhesion of Escherichia coli to medical-grade silicone. The optimal growth conditions of lactobacilli biofilms on silicone were first assessed in 12-well plates. Then, biofilms of L. plantarum were placed in contact with E. coli suspensions for up to 24 h under quasi-static conditions. Biofilm monitoring was performed by determining the number of culturable cells and by confocal laser scanning microscopy (CLSM). Results showed significant reductions of 76%, 77% and 99% in E. coli culturability after exposure to L. plantarum biofilms for 3, 6 and 12 h, respectively, corroborating the CLSM analysis. The interactions between microbial cell surfaces and the silicone surface with and without L. plantarum biofilms were also characterized using contact angle measurements, where E. coli was shown to be thermodynamically less prone to adhere to L. plantarum biofilms than to silicone. Thus, this study suggests the use of probiotic cells as potential antibiofilm agents for urinary tract applications.

BackgroundNeonates with congenital urinary tract dilatation (UTD) may have an increased risk of urinary tract infections (UTI). At present, the management of these patients is controversial and the utility of continuous antibiotic prophylaxis (CAP) remains uncertain as the literature presents contradicting evidence. The aim of this observational study was to assess UTI occurrence in children with prenatal diagnosis of urinary collecting system dilatation without antibiotic prophylaxis.MethodsBetween June 2012 and August 2016, we evaluated the incidence of UTI and the clinical and ultrasonography evolution in 407 children with a prenatally diagnosed UTD. All subjects underwent two prenatal ultrasounds scans (USs) at 20 weeks and 30 weeks of gestation and within 1 month of birth. Patients with a confirmed diagnosis of UTD underwent US follow-up at 6, 12 and 24 months of life. According to the UTD classification system stratify risk, after birth UTD were classified into three groups: UTD-P1 (low risk group), UTD-P2 (intermediate risk group), and UTD-P3 (high risk group). Voiding cystourethrogram was performed in all patients who presented a UTI and in those with UTD-P3. No patient underwent CAP.ResultsPostnatal US confirmed UTD in 278 out of 428 patients with the following rates: UTD-P1 (126), UTD-P2 (95) and UTD-P3 (57). During postnatal follow-up, 6.83% patients presented a UTI (19 out of 278). Eleven out of 19 had vesicoureteral reflux (VUR), and other four were diagnosed with obstructive uropathy and underwent surgical correction. Five patients presented a UTI reinfection.ConclusionThe occurrence of UTI in patients with urinary collecting system dilatation was low. The recent literature reports an increased selection of multirestistant germs in patients with VUR exposed to CAP. This study constitutes a strong hint that routine continuous antibiotic prophylaxis could be avoided in patients with UTD.

Purpose The purpose of this paper is to present the development and validation of the Universal Transformational Management Framework (UTMF), an entrepreneurial tool that guides the development of inclusion-driven strategic management, planning and practice in sport organizations. Design/methodology/approach A range of qualitative data collection techniques was undertaken in this action research: seven cross-sectoral semi-structured interviews; one focus group with sports professionals; a qualitative survey and research group consultations. A matrix analysis, a thematic analysis and secondary research were undertaken to analyze data. Findings The UTMF is a staged framework that embeds principles of behavioral, organizational and transformative change theory, guiding strategic development toward inclusion from a contemplation phase toward an action and maintenance stage. The UTMF is composed of 14 fundamental components identified as key areas that sport entrepreneurs should recognize and address for planning and delivering sport services that leave no one behind. Practical implications Policy makers, management and sport professionals have at their disposal an inclusion-driven framework that challenges their systems and establish mechanisms to leave no one behind. Social implications Organizational transformation can ultimately produce a contagion effect advancing equality and inclusion in society. The UTMF offers a structure for sport entrepreneurs aiming to facilitate and activate social transformation in and through sport. Originality/value The UTMF is a wide-ranging framework to facilitate an orchestrated transformation of sport organizations in order to provide universal services that include marginalized groups and address global challenges identified in intersectional agendas like the SDGs.

This study seeks to better understand the impact of practice-level factors on up-to-date (UTD) rates in children. We compared practice-level vaccination rates for 54 practices to survey data regarding office practices for staffing, vaccine delivery, reminder-recall, and quality improvement. Vaccination rates at 24 and 35 months were analyzed using t tests, analysis of variance, and linear regression. Private practices and those using standing orders had higher UTD rates at 24 months ( P = .01; P = .03), but not at 35 months. Having a pediatrician in the office was associated with higher UTD rates at both 24 and 35 months ( P < .01). Participating in a network and taking walk-in patients were associated with lower UTD rates ( P = .03; P = .03). As the percentage of publicly insured patients decreases, the UTD rate rises at 24 and 35 months ( r = −0.43, P = .001; r = −0.037, P = .007). Reported use of reminder recall-systems, night/evening hours, and taking walk-in patients were not associated with increased UTD rates.

Full textAbstract:
The uterine artery blood flow (UtBF) and renal sympathetic nerve activity (SNA) responses to treadmill exercise were evaluated in 12 nonpregnant (NP) and 17 term pregnant (P) rabbits. UtBF was monitored continuously with a Transonic flowprobe. Rabbits underwent three exercise trials (5-min duration) that varied in absolute workload. The rise in renal SNA with exercise was intensity related. Pregnancy did not affect the average steady-state renal SNA response expressed relative to maximum activity (P 24 ± 1% vs. NP 23 ± 2% of maximum smoke-elicited activity) and increased the average renal SNA response expressed relative to resting activity (P +155 ± 19% vs. NP +84 ± 23% from rest, P = 0.03) At rest, UtBF (P 13 ± 3 vs. NP 1.9 ± 0.3 ml/min) and uterine artery conductance (UtC; P 22 ± 5 vs. NP 2.8 ± 0.5 ml · min-1·mmHg-1 × 10-2) were elevated in the P rabbits. The average exercise-related decreases in UtBF (P -16 ± 4% vs. NP -48 ± 4%) and UtC (P -27 ± 4% vs. NP -54 ± 4%) were attenuated in the P rabbits. Pregnancy does not impair the ability to raise renal SNA but attenuates the uterine artery constrictor response to moderate to heavy dynamic exercise in rabbits. Under normal conditions, the pregnant uterine circulatory bed may be relatively protected from exercise-related redistribution of blood flow.

Selama proses pendistribusian stok darah kepada masyarakat maupun rumah sakit, pihak pasien harus mencari stok darah lansung ke UTD PMI Dumai. Dalam sehari permintaan darah bisa mencapai 10 hingga 15 kantong darah perharinya. Jika stok darah habis, keluarga pasien harus mencari pendonor sendiri untuk mendonorkan darahnya, hal ini menyulitkan bagi keluarga pasien dalam mencari pendonor pengganti. Kurangnya kesadaran masyarakat Kota Dumai dalam pentingnya mendonorkan darah membuat UTD PMI Dumai mengalami kesulitan mengelola stok darah yang ada. Mengingat volume permintaan stok darah setiap harinya yang lebih banyak dibanding pemasukkan stok darah pada UTD PMI. Untuk mengatasi kekosongan stok darah, maka UTD PMI Dumai meminta penggantian darah kepada pihak pasien. Berdasarkan dari masalah tersebut, peneliti melakukan penelitian di UTD PMI Dumai dengan membangun sistem informasi donor darah berbasis website yang dapat mempermudah masyarakat untuk mengaskses stok darah dan data pendonor.

The leading cause of UTD is a variety of obstructive uropathies. The literature on the management and classification systems for UTD is widespread and varied. Diagnosis by sonography benefits the outcome of the affected fetus because early recognition assists in determining further need for prenatal monitoring and postnatal care.

Full textAbstract:
A study was carried out to investigate the effects of feeding low quality non-conventional feeds (NCF) containing phenols and condensed tannins on health and performance characteristics in Omani sheep. Twelve Omani sheep were fed one of two base roughages, urea-treated palm frond (UTPF) or Rhodesgrass hay, (RGH) plus a commercial concentrate for 63 days. Haematological, serum biochemical and urine analyses were used to assess sheep health. Serum protein fractions were measured using electrophoresis. Urea-treated palm frond contained higher levels of polyphenols and condensed tannins and fiber than Rhodesgrass hay or concentrate feed. Animals fed UTPF had lower feed intake (P<0.05) and lower body gain (P<0.001) than those fed RGH. Rumen liquor of UTPF-fed animals had higher pH, ammonia-nitrogen and butyric fatty acid but lower acetic fatty acid (P<0.05). Animals fed UTPF had higher neutrophil (P<0.05) but lower lymphocyte (P<0.05) and monocyte (P<0.001) counts by the end of the trial than those fed RGH. There were no effects of diet on serum albumin or globulin fraction levels or albumin:globulin ratio. There were no major effects on urine analysis but there was a trend by control animals to have higher protein and specific gravity than treated ones. This study indicated that feeding low quality non-conventional feeds containing polyphenols or tannins would reduce body gain and may produce some effects on clinical parameters. Although tannins are known to influence protein digestion and absorption in ruminants, it did not significantly affect the serum protein picture in sheep.

The tannins were extracted in a water bath, using 1500 mL of water and 100g of dry bark (liquor/bark 15:1), with addition of 3% Na2SO3, at a temperature of 70 °C for three hours. The adhesives formulations were based on the gradual replacement of mass of the urea-formaldehyde (UF) adhesive by tannin powder, totalizing four compositions and one control treatment. UTF adhesives were evaluated for their physicochemical properties, shear bond strength (wet and dry) and wood failure. The addition of M. splendens tannins to the urea formaldehyde adhesive promoted an increase in glue line strength. The proportion of 5.0% of tannins proved to be ideal in the formulation of the UTF adhesive, considering all the parameters evaluated. Thus, this study proves the potential use of Amazonian tannins from Myrcia splendens in the partial composition of more sustainable UTF adhesives.

Abstract. The presence of arbitrarily shaped and electrically large objects in the same environment leads to hybridization of the Method of Moments (MoM) with the Uniform Geometrical Theory of Diffraction (UTD). The computation and memory complexity of the MoM solution is improved with the Multilevel Fast Multipole Method (MLFMM). By expanding the k-space integrals in spherical harmonics, further considerable amount of memory can be saved without compromising accuracy and numerical speed. However, until now MoM-UTD hybrid methods are restricted to conventional MoM formulations only with Electric Field Integral Equation (EFIE). In this contribution, a MLFMM-UTD hybridization for Combined Field Integral Equation (CFIE) is proposed and applied within a hybrid Finite Element - Boundary Integral (FEBI) technique. The MLFMM-UTD hybridization is performed at the translation procedure on the various levels of the MLFMM, using a far-field approximation of the corresponding translation operator. The formulation of this new hybrid technique is presented, as well as numerical results.

Abstract. Numerical modeling of problems including composite metallic/dielectric objects with arbitrary shapes and electrically large conducting objects within a common environment is performed in an optimum way with the recently developed powerful hybrid numerical method, which combines the Finite Element Boundary Integral (FEBI) method and the Multilevel Fast Multipole Method (MLFMM) with the Uniform Geometrical Theory of Diffraction (UTD), giving full electromagnetic coupling between all involved objects. In this contribution, the hybrid FEBI-MLFMM-UTD method is extended to double diffracted fields on pairs of straight metallic edges, formulated with the hard and soft scalar diffraction coefficients of UTD. The diffraction points on each pair of edges are determined by an iterative three-dimensional parametric realization of the generalized Fermat's principle. The divergence factor of the double diffracted field is computed by multiplying the appropriate divergence factors of the single diffracted UTD fields on each edge for the particular case. Thereby, the ray caustic distance of the diffracted field at the second edge is determined by linear interpolation between the radii of curvature in the two principal planes of the incident astigmatic ray tube. Further, fast near-field computation in the postprocessing stage of the hybrid method is extended in each translation domain to ray optical contributions due to the presence of electrically large objects, according to the hybridization of MLFMM with UTD. Formulations and numerical results will be presented.

Abstract Background Antenatally diagnosed urinary tract dilatation (UTD) still burdens healthcare providers and parents. This study was conducted to establish long-term outcome in an unselected group of children with antenatally detected UTD. Methods Seventy-one out of 103 children born in 2003–2005 and diagnosed with antenatal UTD agreed to participate in a 12–15-year follow-up including blood and urine samples, a kidney ultrasound exam, and kidney scintigraphy. The records were searched for previous urinary tract infections. Results Among children with an anteroposterior diameter (APD) ≤ 7 mm and no calyceal, kidney, ureteral, or bladder pathology in the early postnatal period, no one tested had reduced estimated glomerular filtration rate (eGFR), albuminuria, or UTD at the follow-up at a mean age of 13.6 years. One child had kidney damage not affecting kidney function. Among children with postnatal APD > 7 mm and/or kidney, calyceal, ureteral, or bladder pathology, 15% had persistent UTD and 32–39% (depending on the method used) had kidney damage. Major postnatal urinary tract ultrasound abnormalities and a congenital anomalies of the kidney and urinary tract (CAKUT) diagnosis were factors associated with an increased risk for permanent kidney damage (odds ratios 8.9, p = 0.016; and 14.0, p = 0.002, respectively). No one had reduced eGFR. One child (1/71, 1%) had a febrile urinary tract infection after the age of 2. Conclusions We conclude that in children with postnatal APD ≤ 7 mm, no calyceal dilatation, normal bladder, ureters, and kidney parenchyma, the outcome is excellent. There is no need for long-term follow-up in these patients.

Full textAbstract:
Although the uniform theory of diffraction (UTD) could be theoretically applied to arbitrarilyshaped convex objects modeled by nonuniform rational B-splines (NURBS), one of the great challenges in calculation of the UTD surface diffracted fields is the difficulty in determining the geodesic paths along which the creeping waves propagate on arbitrarilyshaped NURBS surfaces. In differential geometry, geodesic paths satisfy geodesic differential equation (GDE). Hence, in this paper, a general and efficient adaptive variable step Euler method is introduced for solving the GDE on arbitrarilyshaped NURBS surfaces. In contrast with conventional Euler method, the proposed method employs a shape factor (SF)ξto efficiently enhance the accuracy of tracing and extends the application of UTD for practical engineering. The validity and usefulness of the algorithm can be verified by the numerical results.

Stok darah merupakan salah satu faktor kritis bagi sebuah Unit Transfusi Darah (UTD) yang melayani permintaan darah dari berbagai pihak yang membutuhkan. Peran UTD sebagai penyelenggara pelayanan darah menuntut unit kesehatan tersebut mampu memenuhi kebutuhan karena terkait erat dengan kesehatan dan keselamatan nyawa seseorang. Salah satu permasalahan penting yang dihadapi UTD adalah ketidakpastian permintaan darah sehingga diperlukan cara untuk menjamin ketersediaannya. Hal ini dikarenakan sifat darah yang tidak menentu (perishable) dan tidak dapat diproduksi kembali, serta ketersediaannya yang sangat bergantung pada pendonor darah sukarela. Dalam upaya memberikan solusi, dalam penelitian ini telah dibangun sebuah sistem prediksi persediaan darah menggunakan metode Regresi Linier dengan studi kasus di UTD PMI Kabupaten Bojonegoro pada data-data terkait produk darah Whole Blood (WB) pada semua jenis golongan darah yakni A, B, O, dan AB. Dari pengujian akurasi prediksi menggunakan metode Mean Absolute Percentage Error (MAPE) diperoleh hasil-hasil prediksi yakni produk darah WB golongan A dengan MAPE 18,74% atau Baik, produk darah WB golongan B dengan MAPE 24,37% atau Masuk Akal, produk darah WB golongan O dengan MAPE 17,66% atau Baik, dan produk darah WB golongan AB dengan nilai MAPE 18,67% atau Baik. Sistem prediksi permintaan darah berbasis Regresi Linier ini mampu menunjukkan kinerja dengan rata-rata akurasi prediksi sebesar 80,14% dan dari sisi MAPE diinterpretasikan sebagai prediksi Baik.

Testicular degeneration is an important cause of poor fertility in dogs, but there is little knowledge on its effects on spermatozoa in affected dogs. The study investigated the specific effects of unilateral testicular degeneration (UTD) on spermatozoal characteristics in the testis and epididymis. Ten sexually mature Nigerian indigenous breed of dogs, comprising 5 normal dogs and 5 dogs with UTD were used for the study. The testis and epididymis were removed via orchidectomy for morphological and histopathological evaluation. Sperm in the testis and cauda epididymis were analysed. The samples were grouped into four as N1 (normal right testis), N2 (normal left testis), ND (non-degenerated testis in UTD dogs), and D (degenerated testis in UTD dogs). Data were analysed using one-way ANOVA. There were significant decreases (p<0.001) in testes weight, length, width and volume, and the gonado-somatic index in the D testes compared to the contralateral ND and the N groups. The D group also had significantly lowered epididymal sperm total and progressive motility, viability and concentration (p<0.001), and a decreased testicular sperm concentration (p<0.01). Moreover, there was a decreased percentage (p<0.001) of morphologically normal sperm, with increased prevalence of sperm abnormalities in the D group compared to the other groups. In comparison with the N groups, the ND group had a significantly lowered (p<0.05) epididymal sperm progressive motility, with increased percentage (p<0.01) of sperm with proximal cytoplasmic droplets and looped tails. The findings demonstrated that UTD in dogs adversely affected spermatozoa in the testis and cauda epididymis. There was also evidence of compromised spermatozoa in the epididymis contralateral to the degenerated testis.

A challenge facing immunization registries is developing measures of childhood immunization coverage that contain more information for setting policy than present vaccine series up-to-date (UTD) rates. This study combined milestone analysis with provider encounter data to determine when children either do not receive indicated immunizations during medical encounters or fail to visit providers. Milestone analysis measures immunization status at key times between birth and age 2, when recommended immunizations first become late. The immunization status of a large population of children in the Oregon ALERT immunization registry and in the Oregon Health Plan was tracked across milestone ages. Findings indicate that the majority of children went back and forth with regard to having complete age-appropriate immunizations over time. We also found that immunization UTD rates when used alone are biased towards relating non-UTD status to a lack of visits to providers, instead of to provider visits on which recommended immunizations are not given.

Almost all of the asbestos used in Brazil is mined by an enterprise wholly owned by two European multinational companies, which also produce and market over two-thirds (by weight of asbestos) of the products made from asbestos. About 80 percent of the asbestos used in Brazil is finally consumed in the form of asbestos cement: for roof tiles and roofing panels, wall-board, and domestic and industrial water tanks. A survey of consumer literature and advertising printed by Eternit, S.A., and Brasilit, S.A., disclosed no mention of a potential danger from exposure to asbestos dust, and no recommendations for cutting down exposure to that dust. The situation at smaller, Brazilian-owned firms is reputed to be disastrous from the standpoint of workers' exposure to asbestos dust at the point of production. At a large asbestos-cement manufacturing plant owned by Eternit, however, exposure to asbestos dust (according to company records) seemed to be kept under 2.0 fibers per cc., the present standard for the United States.

Abstract. In this paper a hybrid method combining the Time-Domain Method of Moments (TD-MoM), the Time-Domain Uniform Theory of Diffraction (TD-UTD) and the Finite-Difference Time-Domain Method (FDTD) is presented. When applying this new hybrid method, thin-wire antennas are modeled with the TD-MoM, inhomogeneous bodies are modelled with the FDTD and large perfectly conducting plates are modelled with the TD-UTD. All inhomogeneous bodies are enclosed in a so-called FDTD-volume and the thin-wire antennas can be embedded into this volume or can lie outside. The latter avoids the simulation of white space between antennas and inhomogeneous bodies. If the antennas are positioned into the FDTD-volume, their discretization does not need to agree with the grid of the FDTD. By using the TD-UTD large perfectly conducting plates can be considered efficiently in the solution-procedure. Thus this hybrid method allows time-domain simulations of problems including very different classes of objects, applying the respective most appropriate numerical techniques to every object.

Using additives for polyoxymethylene/silica (POM/SiO2) nanocomposite system is one of suitable solutions to improve processbility, mechanical properties, especially, elongation at break of the material. In this paper, the effect of some additives on the processbility, mechanical properties and morphology of polyoxymethylene/silica (POM/SiO2) nanocomposite was investigated. Zinc stearate (under the commercial name ultraflow – UTF), ethylene-vinyl acetate copolymer (EVA), linear low density polyethylene (LLDPE) and polylactic acid grafted 5 wt.% of polyethylene glycol (PELA) were used as additives for the nanocomposites. The obtained results showed that the preparing process of the POM/SiO2 nanocomposite becam more easily in the presence of PELA, UTF and EVA, corresponding to a lower torque and mixing energy. The PELA caused decrease in the E-modulus or hardness and increase in elongation at break as well as tensile strength of the POM/SiO2 nanocomposites. The SEM images showed that POM and nanosilica were less compatible in the nanocomposite using EVA, LLDPE and UTF and they were more compatible with using PELA.

Blood is one of the most important parts in the human body because blood has a function to circulate the juice, carry oxygen, circulate hormones, and others. If humans reduce blood caused by accidents or anemia, so that humans lack blood or store dirty blood in the body, then it can cause diseases that endanger the health of even someone. Blood donor activity is an activity of the process of blood transfer from donors to people who lack blood. The process is carried out by those who carry out blood processing processes such as the Blood Transfusion Unit (UTD) under the auspices of the Indonesian Red Cross (PMI). UTD PMI Pekanbaru City only has a web-based blood donor information system, so UTD PMI Pekanbaru City wants to keep up with the times where many users use smartphones so they want to upgrade from the web version to the Android version. The reason for the improvement of this system aims to reduce hosting costs to be paid when using a web system and Android-based information system does not require typing too much when the user will carry out an order to the system, its use is not limited by space and place, and does not really need a connection that is prime to run the system. Android-Based Donor Information System in the Indonesian Red Cross Blood Transfusion Unit (UTD PMI) Pekanbaru City can help all people to find out about information about blood donations well by using Android-based smartphones as interesting media.

Full textAbstract:
This paper presents an efficient application of the Time-Domain Uniform Theory of Diffraction (TD-UTD) for the analysis of Ultra-Wideband (UWB) mobile communications for indoor environments. The classical TD-UTD formulation is modified to include the contribution of lossy materials and multiple-ray interactions with the environment. The electromagnetic analysis is combined with a ray-tracing acceleration technique to treat realistic and complex environments. The validity of this method is tested with measurements performed inside the Polytechnic building of the University of Alcala and shows good performance of the model for the analysis of UWB propagation.
