"Climatic zoning for eucalyptus cultivation through strategic decision analysis."

Full textAbstract:
The rapid expansion of eucalyptus cultivation necessitates studies that can identify areas amenable to the planting and development of its different varieties. This study therefore aimed to verify the suitability of two varieties of eucalyptus in the state of Espírito Santo, using Geographic Information Systems supported by strategic decision analysis. Mean precipitation, mean temperature, hydric deficit and land slope data were used as decision factors. These factors were submitted to fuzzy standardization, aggregated and compensated by the Weighted Linear Combination (WLC) process, resulting in the final aptitude mapping. For the reconciliation of conflict areas between the varieties, the Multi-objective Land Allocation (MOLA) module was used to maximize the suitability of the land for the objective. The WLC analysis allowed us to identify the suitability of the areas and with the use of the MOLA module it was possible to resolve the conflict of suitability between the two eucalyptus varieties. Most of the state of Espírito Santo is highly suitable for the the development of varieties. The northwestern region and part of the northern region presented less suitability for both analyzed eucalyptus varieties. Considering the 10,000 km2 most adaptable area for eucalyptus cultivation in the state of Espírito Santo, it was verified that the most suitable areas for planting the two eucalyptus varieties are located in the mountainous regions, part of the southern region and near the northeastern coast.

Land-use optimization is an effective technique to produce optimal benefits in urban land-use planning. There are many approaches and methods to optimize land-use allocation. However, the focus on addressing urban sustainability in land-use optimization is very limited. In this study, we presented a GIS-based multicriteria decision-making (GIS-MCDM) approach to optimize the location of a new residential development considering sustainability dimensions (social, economic, and environmental benefits). Rajshahi City in Bangladesh was taken as a case study. Different types of data, including land use, land cover, ecosystem service value, land surface temperature, and carbon storage, were used to define sustainability criteria. Five physical criteria, three sustainability criteria, and two constraints were used to optimize residential land. Fuzzy membership functions were used to standardize the criteria. The ordered weighted averaging (OWA) was used to produce a residential suitability map. Finally, the multiobjective land allocation (MOLA) module of TerrSet v 19.0 was used to generate optimal locations under an alternative decision scenario. The findings suggest that about 9.00% more sustainability benefits can be achieved using our approach. Using our proposed approach, we also generated six alternative decision scenarios. Among the alternative decision strategies, “high risk–no trade-off” proved to be the most optimal decision strategy that generated the highest sustainability benefit in our case.

Recently, there are increasing demands of a size reduction and a fine interconnection technology, especially for System-in-Package (SiP) module and Package on Package (POP) module in a smart phone and a wearable electronic device. In this study, we presented the Plating Mold Via (PMV) interconnection technology as an innovative fine pitch interconnection solution between substrate I/O pads and package I/O pads in molded System-in-Package (SiP) modules. Similar to the Through Mold Via (TMV), the laser mold via process is first performed to produce a through-via in the Epoxy Mold Compound (EMC) mold, but plating and Soldering process are used simultaneously to produce the metallurgical interconnection to embody the I/O pins of the over-molded surface. After the PMV technology is described, a study of PMV in the molded packaging module is followed. The study is conducted using a test vehicle of SiP module that contains flip chips, Quad Flat Non-leaded (QFN) packages and passives. It is focused on several interface reliability issues, including the interfacial strength of PMV to substrate metal pad as well as to the laser projected area of EMC, and the study of IMC at the plating metal and solder interfaces. The study clearly shows that the PMV technology is a promising fine pitch interconnect solution for various SiP modules.

Full textAbstract:
The High Resolution Stereo Camera (HRSC) on the Mars Express orbiter (Neukum et al. 2004) is a multi-line pushbroom scanner that can obtain stereo and color coverage of targets in a single overpass, with pixel scales as small as 10&amp;thinsp;m at periapsis. Since commencing operations in 2004 it has imaged ~&amp;thinsp;77&amp;thinsp;% of Mars at 20&amp;thinsp;m/pixel or better. The instrument team uses the Video Image Communication And Retrieval (VICAR) software to produce and archive a range of data products from uncalibrated and radiometrically calibrated images to controlled digital topographic models (DTMs) and orthoimages and regional mosaics of DTM and orthophoto data (Gwinner et al. 2009; 2010b; 2016). Alternatives to this highly effective standard processing pipeline are nevertheless of interest to researchers who do not have access to the full VICAR suite and may wish to make topographic products or perform other (e. g., spectrophotometric) analyses prior to the release of the highest level products. We have therefore developed software to ingest HRSC images and model their geometry in the USGS Integrated Software for Imagers and Spectrometers (ISIS3), which can be used for data preparation, geodetic control, and analysis, and the commercial photogrammetric software SOCET SET (® BAE Systems; Miller and Walker 1993; 1995) which can be used for independent production of DTMs and orthoimages. <br><br> The initial implementation of this capability utilized the then-current ISIS2 system and the generic pushbroom sensor model of SOCET SET, and was described in the DTM comparison of independent photogrammetric processing by different elements of the HRSC team (Heipke et al. 2007). A major drawback of this prototype was that neither software system then allowed for pushbroom images in which the exposure time changes from line to line. Except at periapsis, HRSC makes such timing changes every few hundred lines to accommodate changes of altitude and velocity in its elliptical orbit. As a result, it was necessary to split observations into blocks of constant exposure time, greatly increasing the effort needed to control the images and collect DTMs. <br><br> Here, we describe a substantially improved HRSC processing capability that incorporates sensor models with varying line timing in the current ISIS3 system (Sides 2017) and SOCET SET. This enormously reduces the work effort for processing most images and eliminates the artifacts that arose from segmenting them. In addition, the software takes advantage of the continuously evolving capabilities of ISIS3 and the improved image matching module NGATE (Next Generation Automatic Terrain Extraction, incorporating area and feature based algorithms, multi-image and multi-direction matching) of SOCET SET, thus greatly reducing the need for manual editing of DTM errors. We have also developed a procedure for geodetically controlling the images to Mars Orbiter Laser Altimeter (MOLA) data by registering a preliminary stereo topographic model to MOLA by using the point cloud alignment (<i>pc_align</i>) function of the NASA Ames Stereo Pipeline (ASP; Moratto et al. 2010). This effectively converts inter-image tiepoints into ground control points in the MOLA coordinate system. The result is improved absolute accuracy and a significant reduction in work effort relative to manual measurement of ground control. <i>The ISIS and ASP software used are freely available; SOCET SET, is a commercial product.</i> By the end of 2017 we expect to have ported our SOCET SET HRSC sensor model to the Community Sensor Model (CSM; Community Sensor Model Working Group 2010; Hare and Kirk 2017) standard utilized by the successor photogrammetric system SOCET GXP that is currently offered by BAE. In early 2018, we are also working with BAE to release the CSM source code under a BSD or MIT open source license. <br><br> We illustrate current HRSC processing capabilities with three examples, of which the first two come from the DTM comparison of 2007. Candor Chasma (h1235_0001) was a near-periapse observation with constant exposure time that could be processed relatively easily at that time. We show qualitative and quantitative improvements in DTM resolution and precision as well as greatly reduced need for manual editing, and illustrate some of the photometric applications possible in ISIS. At the Nanedi Valles site we are now able to process all 3 long-arc orbits (h0894_0000, h0905_0000 and h0927_0000) without segmenting the images. Finally, processing image set h4235_0001, which covers the landing site of the Mars Science Laboratory (MSL) rover and its rugged science target of Aeolus Mons in Gale crater, provides a rare opportunity to evaluate DTM resolution and precision because extensive High Resolution Imaging Science Experiment (HiRISE) DTMs are available (Golombek et al. 2012). The HiRISE products have ~&amp;thinsp;50x smaller pixel scale so that discrepancies can mostly be attributed to HRSC. We use the HiRISE DTMs to compare the resolution and precision of our HRSC DTMs with the (evolving) standard products. <br><br> We find that the vertical precision of HRSC DTMs is comparable to the pixel scale but the horizontal resolution may be 15&amp;ndash;30 image pixels, depending on processing. This is significantly coarser than the lower limit of 3&amp;ndash;5 pixels based on the minimum size for image patches to be matched. Stereo DTMs registered to MOLA altimetry by surface fitting typically deviate by 10thinsp;m or less in mean elevation. Estimates of the RMS deviation are strongly influenced by the sparse sampling of the altimetry, but range from <thinsp;50thinsp;m in flat areas to ~&amp;thinsp;100thinsp;m in rugged areas.

This study describes the in vitro testing of elastomeric modules. Measurements were first made from study models to establish the clinical distance over which modules are used for canine retraction. From this preliminary study, a typodont, banded with 0·018” × 0·025” standard edgewise brackets, was set up with the canin-molar distance at 28 mm. Modules for canine retraction were then fitted by 11 clinicians. The applied force ranged from 125 to 310 g (221±51 g). A similar, but more extensive study using six different types of modules and two clinician groups (experienced and less experienced clinicians) was then undertaken. Mean force values for different module types ranged from 195±45 g to 318±90 g. There was no statistically significant difference between the force values applied by experienced and less experienced clinicians

The work is devoted to the processing of fly ash wastes obtained from coal combustion. Based on the non-magnetic fraction of fly ash (its particle size of 0-50 μm), an aluminosilicate glue or liquid glass as a cementing component has been obtained. It was represented by a number of silicate modules (SiO2/Me2O molar ratios): 2, 2.5 and 3 (for three different formulations). The shear deformation tests for glued plates with glues of various silicate modules have been carried out. The shear stresses for the samples with silicate modules of 2.0, 2.5, 3.0 were equal to 48, 66 and 34 kPa, respectively. These results suggest that during the production of aluminosilicate glue, the silicate module of 2.5 is more favored for providing the strongest bond between ceramic tiles.

Background. Studies devoted to the analysis of the odontological features of paleoanthropological material and modern population reveal epochal changes in dental structures, as well as ethnic and specific features of the population of individual regions. The study of odontological structures of different epochs allows to obtain information about the reduction and its speed, as well as the prevalence of dental anomalies in individual regions.
 Aim. To identify the changeability of the values of the dimensional parameters of maxillary teeth of the population of the city of Krasnoyarsk, taking into account the time vector.
 Materials and methods. The current odontometric study was conducted on the modern population of Krasnoyarsk (n=331), the craniological material of the Pokrovsky Necropolis (XVII century, n=73), and the Vsekhsvyatskiy Necropolis (XVIII–XIX centuries, n=50). The study was carried out on mesiodistal (MDcor) and vestibulo-oral (VOcor) crown diameters. The modules of teeth crowns (mcor) and the average module of dental crown (mcor M(1-3) (according to the modules of molar crowns) were calculated to characterize the dimensional parameters of teeth crowns in each group in order to determine the general characteristics of the absolute size of the teeth in the jaw.
 Results. Both in female and male samples, the reduction of mesio-distal and vestibulo-oral diameters of some teeth, and accordingly, the reduction of teeth-crown module was revealed. The reduction of maxillary teeth-crown module among the population of Krasnoyarsk of the XVII–XIX is more marked among women. The crown module of right maxillary canine (13 tooth) reduced by 6.41% among women and 3.03% among men by the XXI century. The crown module of 23 tooth reduced by 6,43 % and 2,77% among women and men respectively. Significant reduction of teeth-crown dimensions and modules of teeth 25, 26, 27 by 4,62%, 3,17 % and 1,55% is typical for women, whereas this tendency is not specific to men.
 Conclusions. The analysis of the variability of maxillary teeth-crown modules confirmed the ongoing processes of teeth reduction. The obtained dimensions of the average maxillary teeth-crown module reveal the microdontia in females and mesodontia in males.

"Stoichiometric Assembly of the Cellulosome Generates Maximum Synergy for the Degradation of Crystalline Cellulose, as Revealed byIn VitroReconstitution of the Clostridium thermocellum Cellulosome."

Full textAbstract:
ABSTRACTThe cellulosome is a supramolecular multienzyme complex formed by species-specific interactions between the cohesin modules of scaffoldin proteins and the dockerin modules of a wide variety of polysaccharide-degrading enzymes. Cellulosomal enzymes bound to the scaffoldin protein act synergistically to degrade crystalline cellulose. However, there have been few attempts to reconstitute intact cellulosomes due to the difficulty of heterologously expressing full-length scaffoldin proteins. We describe the synthesis of a full-length scaffoldin protein containing nine cohesin modules, CipA; its deletion derivative containing two cohesin modules, ΔCipA; and three major cellulosomal cellulases, Cel48S, Cel8A, and Cel9K, of theClostridium thermocellumcellulosome. The proteins were synthesized using a wheat germ cell-free protein synthesis system, and the purified proteins were used to reconstitute cellulosomes. Analysis of the cellulosome assembly using size exclusion chromatography suggested that the dockerin module of the enzymes stoichiometrically bound to the cohesin modules of the scaffoldin protein. The activity profile of the reconstituted cellulosomes indicated that cellulosomes assembled at a CipA/enzyme molar ratio of 1/9 (cohesin/dockerin = 1/1) and showed maximum synergy (4-fold synergy) for the degradation of crystalline substrate and ∼2.4-fold-higher synergy for its degradation than minicellulosomes assembled at a ΔCipA/enzyme molar ratio of 1/2 (cohesin/dockerin = 1/1). These results suggest that the binding of more enzyme molecules on a single scaffoldin protein results in higher synergy for the degradation of crystalline cellulose and that the stoichiometric assembly of the cellulosome, without excess or insufficient enzyme, is crucial for generating maximum synergy for the degradation of crystalline cellulose.

Full textAbstract:
Decreased concentration of phospholipids were observed in brain tissue from individuals with dementia compared with controls, indicating phospholipids might be a key variable in development of age-related cognitive impairment. The reflection of these phospholipid changes in blood might provide both reference for diagnosis/monitoring and potential targets for intervention through peripheral circulation. Using a full-scale targeted phospholipidomic approach, 229 molecular species of plasma phospholipid were identified and quantified among 626 senile residents; the association of plasma phospholipids with MoCA score was also comprehensively discussed. Significant association was confirmed between phospholipid matrix and MoCA score by a distance-based linear model. Additionally, the network analysis further observed that two modules containing PEs were positively associated with MoCA score, and one module containing LPLs had a trend of negative correlation with MoCA score. Furthermore, 23 phospholipid molecular species were found to be significantly associated with MoCA score independent of fasting glucose, lipidemia, lipoproteins, inflammatory variables and homocysteine. Thus, the decreased levels of pPEs containing LC-PUFA and the augmented levels of LPLs were the most prominent plasma phospholipid changes correlated with the cognitive decline, while alterations in plasma PC, PS and SM levels accompanying cognitive decline might be due to variation of lipidemia and inflammatory levels.

Hand pose estimation from RGB images has always been a difficult task, owing to the incompleteness of the depth information. Moon et al. improved the accuracy of hand pose estimation by using a new network, InterNet, through their unique design. Still, the network still has potential for improvement. Based on the architecture of MobileNet v3 and MoGA, we redesigned a feature extractor that introduced the latest achievements in the field of computer vision, such as the ACON activation function and the new attention mechanism module, etc. Using these modules effectively with our network, architecture can better extract global features from an RGB image of the hand, leading to a greater performance improvement compared to InterNet and other similar networks.

IntroductionIn depression treatment, most patients do not reach response or remission with current psychotherapeutic approaches. Major reasons for individual non-response are interindividual heterogeneity of etiological mechanisms and pathological forms, and a high rate of comorbid disorders. Personalised treatments targeting comorbidities as well as underlying transdiagnostic mechanisms and factors like early childhood maltreatment may lead to better outcomes. A modular-based psychotherapy (MoBa) approach provides a treatment model of independent and flexible therapy elements within a systematic treatment algorithm to combine and integrate existing evidence-based approaches. By optimally tailoring module selection and application to the specific needs of each patient, MoBa has great potential to improve the currently unsatisfying results of psychotherapy as a bridge between disorder-specific and personalised approaches.Methods and analysisIn a randomised controlled feasibility trial, N=70 outpatients with episodic or persistent major depression, comorbidity and childhood maltreatment are treated in 20 individual sessions with MoBa or standard cognitive–behavioural therapy for depression. The three modules of MoBa focus on deficits associated with early childhood maltreatment: the systems of negative valence, social processes and arousal. According to a specific questionnaire-based treatment algorithm, elements from cognitive behavioural analysis system of psychotherapy, mentalisation-based psychotherapy and/or mindfulness-based cognitive therapy are integrated for a personalised modular procedure.As a proof of concept, this trial will provide evidence for the feasibility and efficacy (post-treatment and 6-month follow-up) of a modular add-on approach for patients with depression, comorbidities and a history of childhood maltreatment. Crucial feasibility aspects include targeted psychopathological mechanisms, selection (treatment algorithm), sequence and application of modules, as well as training and supervision of the study therapists.Ethics and disseminationThis study obtained approval from the independent Ethics Committees of the University of Freiburg and the University of Heidelberg. All findings will be disseminated broadly via peer-reviewed articles in scientific journals and contributions to national and international conferences.Trial registration numberDRKS00022093.

Full textAbstract:
Background. The exponential growth of research concerning a role of morphological modularity and integration in evolution has taking place from the beginning of the century. It was especially noted that inter-level integration should manifest itself, first of all, in the congruent variability of the modules of different structural levels. We analyzed congruence between the interspecific variability of the first lower molar (m1) masticatory surface and the mtDNA Cytb gene in ten species of the gray voles Microtus s.l. from the point of view of the modular organization.
 Materials and methods. In total, 5306 pairs of chewing surface contours of vole molar m1 were investigated. Thirty one different morphotypes and 187 their different combinations are identified: 30 symmetric and 157 asymmetric. 576 sequences of the Cytb mtDNA gene from the GenBank database are used. Climatic data are taken from the website Climate:Date.org. Data are processed using a DJ-method. The morphogenetic matrix of Euclidean distances between species is obtained from the frequencies of m1 morphotypes co-occurrence from the right and left sides of the lower jaw, and the molecular-genetic one from the frequencies of synonymous codon substitutions. The algorithm is realized in the Jacobi 4 package.
 Results. A high correlation (r = 0.847) between the first principal component of the molecular-genetic distance matrix and second principal component of the morphogenetic one is found. From the standpoint of the modular organization of the phenotype, the principal components of these matrices are treated as variability modules. The molecular-genetic module is caused by change of frequencies of the codons ACC and GCA along geo-climatic gradient, and morphogenetic one various aspects of the m1 asymmetry.
 Conclusions. The proposed approach allowed to identify two congruently varying modules from different trait systems of the studied species along the geo-climatic gradient.

AbstractLet A be a finite dimensional associative K-algebra with an identity over an algebraically closed field K, d a natural number, and modA(d) the affine variety of d-dimensional A-modules. The general linear group Gld(K) acts on modA(d) by conjugation, and the orbits correspond to the isomorphism classes of d-dimensional modules. For M and N in modA(d), N is called a degeneration of M, if TV belongs to the closure of the orbit of M. This defines a partial order ≤deg on modA(d). There has been a work [1], [10], [11], [21] connecting ≤deg with other partial orders ≤ext and ≤deg on modA(d) defined in terms of extensions and homomorphisms. In particular, it is known that these partial orders coincide in the case A is representation-finite and its Auslander-Reiten quiver is directed. We study degenerations of modules from the additive categories given by connected components of the Auslander-Reiten quiver of A having oriented cycles. We show that the partial orders ≤ext, ≤deg and < coincide on modules from the additive categories of quasi-tubes [24], and describe minimal degenerations of such modules. Moreover, we show that M ≤degN does not imply M ≤ext N for some indecomposable modules M and N lying in coils in the sense of [4].

Full textAbstract:
We used 31P MRS (magnetic resonance spectroscopy) measurements of energetic intermediates [ATP, Pi and PCr (phosphocreatine)] in combination with the analytical tools of metabolic control analysis to study in vivo energy metabolism in the contracting skeletal muscle of anaesthetized rats over a broad range of workload. According to our recent MoCA (modular control analysis) used to describe regulatory mechanisms in beating heart, we defined the energetic system of muscle contraction as two modules (PCr-Producer and PCr-Consumer) connected by the energetic intermediates. Hypoxia and electrical stimulation were used in this in vivo study as reasonably selective modulations of Producer and Consumer respectively. As quantified by elasticity coefficients, the sensitivities of each module to PCr determine the control of steady-state contractile activity and metabolite concentrations. The magnitude of the elasticity of the producer was high (4.3±0.6) at low workloads and decreased 5-fold (to 0.9±0.2) at high workloads. By contrast, the elasticity of the consumer remained low (0.5–1.2) over the range of metabolic rates studied. The control exerted by each module over contraction was calculated from these elasticities. The control of contraction was found on the consumer at low workloads and then swung to the producer, due to the workload-dependent decrease in the elasticity of producer. The workload-dependent elasticity and control pattern of energy production in muscle is a major difference from heart. Since module rate and elasticity depend on the concentrations of substrates and products, the absence of homoeostasis of the energetic intermediates in muscle, by contrast with heart, is probably the origin of the workload-dependent elasticity of the producer module.

Let A be an artin algebra over a commutative artin ring R, mod A be the category of finitely generated right A-modules, and rad∞ (modA) be the infinite power of the Jacobson radical rad(modA) of modA. Recall that A is said to be representation-finite if mod A admits only finitely many non-isomorphic indecomposable modules. It is known that A is representation-finite if and only if rad∞ (mod A) = 0. Moreover, from the validity of the First Brauer–Thrall Conjecture [26, 2] we know that A is representation-finite if and only if there is a common bound on the length of indecomposable modules in mod A.

Full textAbstract:
This paper provides an in-depth study of the assembly production variance problem through the largest supplier of General Motors China. We focus on the production variance problem in an unreliable assembly (MOBA) system with a finite inter-station buffer, focusing on two of the central issues, namely the output variance as well as the delivery schedule variance. We model every subsystem's departure procedure in the MOBA system using the Markov Arrival Process (MAP) approach. Through the approximate use of MAP, we successfully shorten the time needed to calculate the output variance as well as delivery schedule variance of a large-scale MOBA system, which improves the efficiency of the system while ensuring that it meets the customer's needs. The relationship between production variance and system parameters is also studied, which is of substantial significance for optimizing the productivity of MOBA systems and improving customer satisfaction.

Full textAbstract:
In the highly competitive injection molding industry, the ability to effectively collect information from various sensors installed in molds and machines is of the utmost relevance, enabling the development of data-based Industry 4.0 algorithms. In this work, an alternative to commercially available monitoring systems used in the industry was developed and tested in the scope of the TOOLING 4G project. The novelty of this system is its affordability, simplicity, real-time data acquisition and display in an intuitive Graphical User Interface (GUI), while being open-source firmware and software-based. These characteristics, and their combinations have been present in previous works, but, to the authors’ knowledge, not all of them simultaneously. The system used an Arduino microcontroller-based data acquisition module that can be connected to any computer via a USB port. Software was developed, including a GUI, prepared to receive data from both the Arduino module and a second module. In the current state of development, data corresponding to a maximum of six sensors can be visualized, at a rate of 10 Hz, and recorded for later usage. These capabilities were verified under real-world conditions for monitoring an injection mold with the objective of creating the basis of a platform to deploy predictive maintenance. Mold temperature, cavity pressure, 3-axis acceleration, and extraction force data showed the system can successfully monitor the mold and allowed the clear distinction between normal and abnormal operating patterns.

The gating system is usually made up of the sprue, the runner, the gate and the slag well. It is an important component of the mold. On the basis of relationship among runner’s geometry, the pressure fall of plastic melt flowing in runner, flow rate and material properties, we can use the UDF library features and Pro / Toolkit functions in PRO / E software to do the second development of PRO / E software. As a result, we can establish the CAD module of gating system for the injection mold. The module has the perfect function and good generality and can help the designer for cost reduction. It may be used whenever you want to use. The PRO / E software has a powerful function to design mold. Taking these as a base, it is very convenient for the module to design the gating system of injection mold.

Full textAbstract:
Levosimendan is a calcium sensitizer developed for the treatment of heart failure. It increases contractile force by enhancing the sensitivity of myofilaments to calcium. Besides this sensitizing effect, the drug has also been reported to show some inhibitory action on phosphodiesterase 3 (PDE3). The inotropic effects of levosimendan have been studied on guinea pig paced perfused hearts by using modular control analysis (MoCA) (Diolez P, Deschodt-Arsac V, Raffard G, Simon C, Santos PD, Thiaudiere E, Arsac L, Franconi JM. Am J Physiol Regul Integr Comp Physiol 293: R13–R19, 2007.), an integrative approach of heart energetics using noninvasive 31P NMR. The aim was to evaluate quantitatively the respective effects of this drug on energy supply and demand modules. Under our experimental conditions, 0.7 μM levosimendan induced a 45% increase in paced heart output associated with a 7% decrease in phosphocreatine and a negligible increase in oxygen consumption. Because MoCA allows in situ study of the internal regulations in intact beating heart energetics, it was applied to describe quantitatively by which routes levosimendan exerts its inotropic action. MoCA demonstrated the absence of any significant effect of the drug on the supply module, which is responsible for the lower increase in oxygen consumption, compared with epinephrine, which increases the ratio between myocardial oxygen consumption and cardiac contraction. This result evidences that, under our conditions, a possible effect of levosimendan on PDE3 activity and/or intracellular calcium remains very low on mitochondrial activity and insignificant on integrated cardiac energetics. Thus, levosimendan inotropic effect on guinea pig heart depends almost entirely on the calcium-sensitizing properties leading to myofilament activation and the concomitant activation of energy supply by the decrease in PCr, therefore improving energetic efficiency of contraction.

In this paper the latest versions of six publicly available bathymetry models: DTU10bat, EMODnet 2018, ETOPO1, GEBCO 2020, Smith and Sandwell V20.1 and SRTM15+ V.2.1. are compared and evaluated in the area of continental shelf of Croatia settled along well intended east Adriatic coast. Survey data in the area is not available through open access data bases, but publicly accessible in agreement with data holders (hydrographic institute, research centres and industry). These grids provide alternative sources of information about seafloor topography. Marine researchers should be acquainted with the main characteristics as well as pros and cons of bathymetry models in order to choose the best one for a specific purpose. In this paper the most important characteristics and information about grids are presented: resolution, coverage, release date, horizontal and vertical datum, data source, registration method, producer and link to website with an emphasis on the underlying source data. The underlying source data is one of the most important parameters that determine the quality of the bathymetric model. Hypsometry curve that is describing the area distribution of depth is calculated for each bathymetry model over the test area of the east Adriatic. For pixel to pixel comparison, grids were resampled to same one-minute resolution and absolute differences between models are calculated in identical points. Absolute differences between models show level of mutual compatibility between models as well as areas of highest disagreements that indicate the presence of outliers or systematic errors within models. In order to demonstrate how well publicly available bathymetry models fit the true topography of the sea floor, grids were compared to high-resolution digital bathymetry model interpolated from the multibeam survey in the area of Murter Sea. This paper should assist in the choice of a most suited bathymetry grid in future maritime studies in the Adriatic.

Full textAbstract:
A motor core is formed by stacking iron sheets on top of each other. Traditionally, there are two stacking methods, riveting and welding, but these two methods will increase iron loss and reduce usage efficiency. The use of resin is the current developmental trend in the technology used to join iron sheets, which has advantages including lowering iron loss, smoothing magnetic circuits, and generating higher rigidity. The flow behavior of resin in gluing technology is very important because it affects the dipping of iron sheets and the stacking of iron sheets with resin. In this study, a set of analytical processes is proposed to predict the flow behavior of resin through the use of computer-aided engineering (CAE) tools. The research results are compared with the experimental results to verify the accuracy of the CAE tools in predicting resin flow. CAE tools can be used to predict results, modify modules for possible defects, and reduce the time and costs associated with experiments. The obtained simulation results showed that the filling trend was the same as that for the experimental results, where the error between the simulation results for the final dipping process and the target value was 0.6%. In addition, the position of air traps is also simulated in the dipping process.

Full textAbstract:
A novel multidrug-resistance plasmid, pKLH80, previously isolated from Psychrobacter maritimus MR29-12 found in ancient permafrost, was completely sequenced and analysed. In our previous studies, we focused on the pKLH80 plasmid region containing streptomycin and tetracycline resistance genes, and their mobilization with an upstream-located ISPpy1 insertion sequence (IS) element. Here, we present the complete sequence of pKLH80 and analysis of its backbone genetic structure, including previously unknown features of the plasmid’s accessory region, notably a novel variant of the β-lactamase gene bla RTG-6. Plasmid pKLH80 was found to be a circular 14 835 bp molecule that has an overall G+C content of 40.3 mol% and encodes 20 putative ORFs. There are two distinctive functional modules within the plasmid backbone sequence: (i) the replication module consisting of repB and the oriV region; and (ii) the mobilization module consisting of mobA, mobC and oriT. All of the aforementioned genes share sequence identities with corresponding genes of different species of Psychrobacter. The plasmid accessory region contains antibiotic resistance genes and IS elements (ISPsma1 of the IS982 family, and ISPpy1 and ISAba14 of the IS3 family) found in environmental and clinical bacterial strains of different taxa. We revealed that the sequences flanking bla RTG-6 and closely related genes from clinical bacteria are nearly identical. This fact suggests that bla RTG-6 from the environmental strain of Psychrobacter is a progenitor of bla RTG genes of clinical bacteria. We also showed that pKLH80 can replicate in different strains of Acinetobacter and Psychrobacter genera. The roles of IS elements in the horizontal transfer of antibiotic resistance genes are examined and discussed.

We have measured both longitudinal and transverse ultrasonic sound velocities of these glasses using a pulse-echo superposition method. These ultrasonic velocities have been used to calculate the elastic moduli, Poisson ratio, and Debye temperatures. The variations of density, molar volume, ultrasonic sound velocities, elastic moduli, Poisson ratio, and Debye temperature have been discussed with respect to Er2O3 concentration.

The search for effective technologies for the remediation of technologically polluted natural objects is an urgent problem of environmental protection. At the experimental site near Kola MMC JSC (Murmansk region, Monchegorsk), experiments have been carried out on the use of mining waste to create phyto-adsorption sites in technologically polluted territories. During the experiments, filtering modules were used to study the processes of sorption/desorption of emission components with vermiculite-sungulite composition materials obtained by enriching phlogopite mining waste (Murmansk Region, Kovdor). To load two types of filtering modules designed to study open (I) and partially open (II) systems, the authors have used the initial and heat-treated granular sungulite, as well as slurry products (the content of sungulite and vermiculite was 30 %). As a control option, an experiment has been carried out using pure peat, selected in the vicinity of Apatity (Murmansk region). As a result of the study, the layer-by-layer content of the acid-soluble (or semi-gross) form of the components has been determined; the toxicity module has been calculated (the ratio of the total molar content of metals (Cu + Ni) and macronutrients (Ca + Mg)) used to assess the possible toxic effect of products in relation to plants. Pure peat has proved to possess the greatest sorption ability, however, at the end of the experiment, the highest degree of toxicity has been observed for peat; mineral products have been the least toxic. An analysis of the distribution of metals among the layers of filtering modules (II) has shown that intense accumulation of metals is observed in the upper layers; with increasing depth (layers 2-4) there is a gradual decrease in the copper content, in some products nickel is leached in the lower layers. The results of the study have shown that for loading phyto-adsorption sites it is advisable to use a granular sungulite product characterized by good sorption ability and low toxicity.

Full textAbstract:
To determine thermochemical characteristics: enthalpy, molar heat capacity and Gibbs energy of formation of silicides, borides and carbides in an alloy of a given composition (40Fe–31Ni–16Cr–5Cu–5Si–2B–1C) calculation methods were used using mixed GGA and GGA + U schemes (semi-empirically tuned generalized gradient approximations). Three modules of the HSC Chemistry 6.0 software package (Metso Outotec, version 6.0, Espoo, Finland) were used in the study. First, the “Reaction Equation” module was used to calculate the change in Gibbs free energy at different temperatures. Secondly, to calculate the composition of each chemical in the equilibrium state, the module “Equilibrium Composition” was used (“Equilibrium compositions” – calculation of equilibrium compositions of phases in the presence of reversible chemical reactions). Thirdly, the module “H, S, C and G diagrams” (“Graphs of thermodynamic functions” – plotting thermodynamic functions) was used to determine the relative phase stability of compounds depending on temperature in the form of Ellingham diagrams. The results of thermochemical modeling showed that the temperature dependences of the heat capacity of the formation of hardening compounds in the alloy increase with increasing temperature. Thermodynamic calculations of the enthalpies of the hardening phases in the alloy showed that at temperatures 1400°C, silicides, borides, and carbides are formed. ∆G(T) of silicides, there is an increase in the values of the Gibbs energy and a tendency towards stability with increasing temperature. During the formation of borides in the alloy, one can see a strong absorption of heat, an increase in the Gibbs energy in the studied temperature range. The results of calculating the Gibbs energy as a function of temperature showed the formation of carbides Ni3C, Fe3C, SiC, B4C, Cr3C2, Cr4C, Cr7C3. The formation of phases occurs with a decrease in the values of the Gibbs energy to a temperature of ~1500°C. A further increase in temperature indicates the absorption of heat, which is associated with a high ordering temperature of the carbide structures. Thus, the thermochemical study justified the formation of silicides, borides, carbides in the alloy 40Fe–31Ni–16Cr–5Cu–5Si–2B–1C.

In this research, the optimal grinding condition has been obtained by design of experiment(DOE) for the development of aspheric lens for the 3 Mega Pixel, 2.5x optical zoom camera-phone module. Also, the WC mold was processed by the method of ultra precision grinding under this optimal grinding condition. The influence of DLC coating on form accuracy (PV) and surface roughness(Ra) of the mold was evaluated through measurements after DCL coating using ion plating on the ground mold. Also, aspheric glass lens was molded by before and after the use of the mold of DLC coating, respectively. The optical characteristics of each sample, which were molded by the different mold, were compared with each other.
