Numerical Simulation of Solar Radiation and Conjugate Heat Transfer through Cabin Seat Textile
Authors: Zhang Yijie , Jia Juhong 
Published: October 2020

AbstractThe solar radiation and the conjugate heat transfer through the cabin seat fabric were investigated numerically with a focus on a comparative analysis of various fabric solar reflectance or reflectivity (SR) and inlet cooling air velocity. For this purpose, 3D compressible Reynolds-averaged Navier–Stokes equations with the low Reynolds number turbulence model were utilized to simulate the airflow in the cabin. The discrete ordinate radiation model was adopted to describe the solar radiation. The conjugate heat transfer between the airflow and the fabric seats was included. The airflow temperature, radiative heat flux, and radiative heat transfer through the fabrics in a fixed cross section were studied. The results demonstrate that the increase in fabric SR leads to the increase in energy reflected to the atmosphere, which will bring about a lower temperature on the seat fabric. The decrease in emissivity and the energy absorbed results in the lower heat transfer and heat radiation and leads to the improvement of the cabin thermal environment. The high-temperature gradient near the seat causes the forced air circulation and is beneficial for the improvement of the thermal comfort. However, the cooling effect is not so obvious near the cabin seats when the inflow speed is increased.

Published: October 2020

Abstract
The main aim of the presented research was to obtain antibacterial fibers containing nanosilica with immobilized silver nanoparticles. The nanomodifier in an amount of 250 ppm, 500 ppm, 1,000 ppm, and 2,000 ppm were introduced into the cellulose fiber matrix during the cellulose dissolution process. In order to assess the influence of the nanomodifier's amount in the fiber on the antibacterial activity of modified fiber, a quantitative test of the antibacterial activity of the fibers was performed. The basic parameters of modified fibers, such as the mechanical and hygroscopic, were estimated. The size and shape of the nanomodifier in the selected fibers, as well as microanalysis of the polymer matrix, were examined. The investigations were conducted by Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Energy Dispersive Spectrometry (EDS). The obtained results allowed the selection of optimal fibers with strong antibacterial properties that can be potentially used for personal protection or medical purposes.

Published: October 2020

Abstract
Domain-Specific Languages (DSLs) are programming languages designed specifically to express solutions to problems in a particular domain. It is said they foster productivity and quality. In this work we describe CRUDyLeaf, a DSL focused on the generation of Spring Boot REST APIs from entity CRUD operations. Spring Boot is an open source Java-based framework used to implement the REST architecture style. It has gained popularity among developers mainly because it allows to build stand-alone and production ready software applications (avoiding the use of an application server). Through seven proposed stages (domain immersion, golden application implementation, syntax definition, meta model generation, code generator implementation, deployment, and refinement) we describe the development of this DSL. We also exemplify and evaluate the proposed DSL. Our findings suggest a yield automation rate of 32.1 LOC (Lines Of Code) for each LOC written in this DSL, among other observed benefits.

Abstract
Recent Activity Daily Living (ADL) not only tackles simple activities, but also caters to a wide range of complex activities. Although the same activity has been carried out under the same environmental conditions, the acceleration signal obtained from each subject considerably differs. This happens due to the pattern of action generated for each subject is diverse based on several aspects such as subject age, gender, emotion and personality. This project therefore compares the accuracy of various machine learning models for ADL classification. On top of that, this research work also scrutinizes the effectiveness of various feature selection methods to identify the most relevant attribute for ADL classification. As a result, Random Forest was able to achieve the highest accuracy of 83.3% on subject independent matter in ADL classification. Meanwhile, CFS Subset Evaluator is considered to be a good feature selector as it successfully selected the 8 most relevant features compared with Correlation and Information Gain Evaluator.
Multiscale Transform and Shrinkage Thresholding Techniques for Medical Image Denoising – Performance Evaluation
Authors: Nisha S. Shajun , Raja S. P. 
Published: October 2020

Abstract
Due to sparsity and multiresolution properties, Mutiscale transforms are gaining popularity in the field of medical image denoising. This paper empirically evaluates different Mutiscale transform approaches such as Wavelet, Bandelet, Ridgelet, Contourlet, and Curvelet for image denoising. The image to be denoised first undergoes decomposition and then the thresholding is applied to its coefficients. This paper also deals with basic shrinkage thresholding techniques such Visushrink, Sureshrink, Neighshrink, Bayeshrink, Normalshrink and Neighsureshrink to determine the best one for image denoising. Experimental results on several test images were taken on Magnetic Resonance Imaging (MRI), X-RAY and Computed Tomography (CT). Qualitative performance metrics like Peak Signal to Noise Ratio (PSNR), Weighted Signal to Noise Ratio (WSNR), Structural Similarity Index (SSIM), and Correlation Coefficient (CC) were computed. The results shows that Contourlet based Medical image denoising methods are achieving significant improvement in association with Neighsureshrink thresholding technique.
PS-PC: An Effective Method to Improve VoIP Technology Bandwidth Utilization over ITTP Protocol
Authors: Abualhaj Mosleh M. , Al-Khatib Sumaya N. , Shambour Qusai Y. 
Published: October 2020

Abstract
Voice over IP (VoIP) wastes a valuable amount of bandwidth because of its large packet header size compared to its small packet payload. The main objective of this paper is to reduce the amount of this wasted bandwidth, by proposing a new packets coalescence method, called Payload Shrinking and Packets Coalesce (PS-PC). The proposed PS-PC method reduces the amount of the wasted bandwidth by i) coalesces a group of VoIP packets in one header instead of a separate header to each packet and ii) shrinks the VoIP packet payload to a smaller one based on a certain algorithm. The proposed PS-PC method is deployed at the sender side VoIP gateway that represents an exit point to a myriad number of simultaneous VoIP calls. The performance evaluation showed better bandwidth usage when deploying the proposed PS-PC method with ITTP protocol in comparison to the traditional ITTP protocol without the PS-PC method.
A Novel Feature Descriptor for Face Anti-Spoofing Using Texture Based Method
Authors: Raghavendra R. J. , Kunte R. Sanjeev 
Published: October 2020

AbstractIn this paper we propose a novel approach for face anti-spoofing called Extended Division Directional Ternary Co-relation Pattern (EDDTCP). The EDDTCP encodes co-relation of ternary edges based on the centre pixel gray values with its immediate directional neighbour and its next immediate average directional neighbour, which is calculated by using the average of cornered neighbours with directional neighbours. The proposed method is robust against presentation attacks by extracting the spatial information in all directions. Three Experiments were performed by using all the four texture descriptors (LBP, LTP, LGS and EDDTCP) and the results are compared. The proposed face anti-spoofing method performs better than LBP, LTP and LGS.

Published: October 2020

Abstract
The article is devoted towards the application of managerial accounting for deliverology development at the local government level in countries and comparing them to the stage of fiscal decentralisation implementation in Ukraine. The aim of the article is to show how the application of the managerial accounting approach in the public sector can contribute to the introduction of deliverology at the local level using Ukraine as an example. The methodology is based on the application of Difference in Difference method for the implementation of deliverology at the local government level. It has been proved that the use of multi-criteria decision-making methods in the analysis of the performance of budget programmes at the local level will contribute to the improvement of public services delivery. The main contribution of this study is to provide the basis for developing recommendations for the use of a single or uniform standard of electronic databases on regional development indicators and local budgets. This will help to ensure operational control over deviations of actual indicators from planned ones, as well as identify regions where local authorities are using resources inefficiently.
Effects of histamine and sodium hypochlorite on prooxidand state in the rats erytrocytes
Authors: Harasym Nataliya , Mandzynets Svitlana , Sanahursky Dmytro 
Published: October 2020

Abstract
We studied the simultaneous influence of histamine and sodium hypochlorite (SH) on lipid peroxidation processes, as well as the level of structural changes in membranes (via the content of sialic acid) in rat erythrocytes. We established that histamine affects lipid peroxidation processes with the formation of lipid hydroperoxides, damages proteins and reduces the content of sialic acids, which leads to changes in the surface charge of red blood cells. However, the simultaneous action of histamine and low SH concentration has a positive effect in that it corrects the pro-oxidant state of erythrocytes. Hence, the content of lipid hydroperoxides, TBA-active products, carbonyl groups of proteins and sialic acids were mainly reduced after the simultaneous action of histamine and SH at all studied concentrations during the rehabilitation period.

Abstract

Introduction. When considering the array of biomedical problems associated with facial nerve palsy (FNP), it is apparent that the problem of choosing an effective type of facial nerve transfer is of paramount relevance. Hence, it is to the pursuit of a solution to the above stated problem that our study is devoted.

Materials and methods. We analyzed the data obtained as a result of assessing the outcome of 149 patients with trauma-caused FNP who had undergone surgical treatments in the period between 2001-2018. The FN nerve transfer techniques utilized were as such: for group 1 – the use as a donor nerve the branch of the accessory nerve innervating the sternocleidomastoid muscle (n=87); group 2 – the descending branch of the hypoglossal and the branch of the accessory nerve (n=62).

Results. In groups 1–2, the FN nerve transfer significantly improved FN function (p <0.01; Wilcoxon Matched Pairs Test), and most patients (n=135; 90.6%) noted an improvement in the clinical status up to degree II-III on the House-Brackmann scale (good result).

Conclusion. The use of the accessory nerve branches to the sternocleidomastoid muscle, as donated, ensures restoration of FN function to levels II-III on the House-Brackmann scale in 89.7% of all operated patients, and the results it achieves do not differ from those of the technically more complex nerve transfer of FN by descending branch of the hypoglossal nerve with combination of branches of the accessory nerve.

Abstract

Aim. Chemo-herbal combinations promise new clinical anticancer therapeutic modalities. The current study investigated and compared the in vitro effects of a bromelain-based chemo-herbal combination to/with cisplatin or 5-FU, with regard to the proliferation and apoptosis of human gastric AGS and breast MCF7 cell lines.

Material and methods. AGS and MCF7 cells were either treated with different concentrations of bromelain, cisplatin or 5-FU; or with bromelain-cisplatin and bromelain-5-FU combinations for 48h. Cell proliferative inhibition and inductive apoptosis were appraised using MTT assay and flowcytometry, respectively. Kruskal-Wallis and Dunn’s tests were used to analyze differences in cell groups’ means.

Results. AGS proliferation was adversely affected by single treatments of bromelain and cisplatin (p <0.003) or 5-FU (p <0.05). The anti-proliferative impact of single treatments was more pronounced on MCF7 cells. The bromelain-cisplatin combinations displayed synergistic effect on MCF7 cells (CIs ≤1), while being additive or antagonistic with cisplatin IC30 and IC40 to AGS cell proliferation, respectively. In addition, bromelian-5-FU combinations showed synergistic effect on AGS cells, while antagonistic to MCF7 cells. In terms of cell apoptosis induction, bromelain (IC30)-cisplatin (IC20) displayed additive effect on MCF7, compared to cisplatin single treatment (p <0.04), while bromelain (IC40)-5-FU (IC10) and bromelain (IC30)-5-FU (IC20) afforded additive apoptotic effects on AGS (p <0.04) and MCF7 (p <0.05), respectively, in comparison to 5-FU single treatment.

Conclusion. A bromelain-based combination using cisplatin showed concordant effects on cell proliferation impediment and apoptotic induction on MCF7, while the same results were noticed with a bromelain-5-FU combination to AGS cells. The bromelain-based chemo-herbal pathways should further be investigated in the frame of multi-chemotherapeutic drugs researches.
Feeding Ecology of Pachypterus atherinoides (Actinopterygii; Siluriformes; Schilbeidae): A Small Freshwater Fish from Floodplain Wetlands of Northeast India
Authors: Gogoi Budhin , Das Debangshu Narayan , Saikia Surjya Kumar 
Published: October 2020

Abstract
The feeding ecology of Pachypterus atherinoides was investigated for two consecutive years (2013-2015) from floodplain wetlands in the Subansiri river basin of Assam, North East India. The analysis of its gut content revealed the presence of 62 genera of planktonic life forms along with other animal matters. The organization of the alimentary tract and maximum Relative Mean Length of Gut (0.511±0.029 mm) indicated its carnivorous food habit. The peak gastro-somatic index (GSI) in winter-spring seasons and summer-rainy seasons indicated alteration of its feeding intensity. Furthermore, higher diet breadth on resource use (Levins’ and Hurlbert’s) with zooplankton compared to phytoplankton and total plankton confirmed its zooplanktivore habit. The feeding strategy plots also suggested greater preference to zooplankton compared to phytoplankton. The organization of its gill rakers specified a secondary modification of gut towards either carnivory or specialized zooplanktivory. So, the fish may be a carni-omnivore with preference to zooplankton.

Published: October 2020

Abstract
A study was conducted to investigate the effects of natural zeolites as a water clarifier on the heavy metal removal efficiency from the underground saltwater used for rearing Dicentrarchus labrax fry. Five concentrations of zeolites were tested: 0 (Z0), 2.5‰ (Z2.5), 5‰ (Z5), 7.5‰ (Z7.5) and 10‰ (Z10). Fry with an initial body weight of 1.53±0.018 g/fish were stocked in 15 aquaria at a density of 10 fry/aquarium. The fish were fed a commercial diet (42% protein and 12.34% lipid) twice daily (09:30 and 14:00) at 5% of their body weight per day for 42 days. Growth, feed utilization, survival and heavy metal removal efficiency were evaluated. The growth performance and feed utilization indices gradually improved with increasing zeolite concentration, with the most significant (P≤0.05) values detected at Z10. The survival rate decreased significantly at Z10 compared with the control (Z0). Increasing the zeolite concentration significantly (P≤0.05) improved the removal efficiency of heavy metals in the rearing water with adsorption selectivity of Pb˃Cd˃Fe˃Cu˃Zn. Furthermore, an increase in the detoxification rate of heavy metals in fish flesh with increasing zeolite level was detected with the removal selectivity of Fe˃Cu˃Zn˃Pb˃Cd. In conclusion, it can be stated that natural zeolites can be used effectively to reduce heavy metals in polluted waters and subsequently in fish flesh in addition to improving fish performance.

Published: October 2020

Abstract
An ecosystem engineer is a species that indirectly changes the availability of resources for other organisms via physical modification of the habitat. A good example of such species is Ardea cinerea L. – a big waterbird that forms colonies up to a few hundreds of nests during the breeding season. The colonies modify the habitat in the close vicinity of the nests mainly through heavy input of organic matter (feces, dropped or regurgitated food leftovers, eggshells, dead birds, etc.), which in turn affects vegetation. In our previous study, we observed that the probability of occurrence of non-forest species under the nests was 29.5 times higher in control plots in two types of forest vegetation (oligotrophic pine forest and riparian mixed forest). Adaptation for long-distance dispersal turned out to be insignificant for the probability of species occurrence, which suggested that the diaspores of those species must have been present in the forest soil before the establishment of the grey heron colony. In the present study, we used the seedling emergence method to compare the structure of the soil seed bank in breeding sites and control plots in two forest ecosystems mentioned above. We also tested whether the increased amount of nitrates in soil had a positive effect on the rate of germination and growth of seedlings. The results have shown that some reservoir of ruderal species was indeed present in the control plots, although their amount was higher under the heronries. We have proved that the number of germinating seeds of ruderal species depends on the concentration of nitrate in the soil of the pine forest. Comparison of the dry weight of 30- and 60-day-old seedlings of Rumex acetosella (pine forest) and Betula pendula (riparian forest) from the control and breeding sites showed an increased size of seedlings coming from the breeding sites of both forest communities.

Published: October 2020

Abstract
The landscape of south-western Slovakia is characterised by anthropogenous reshaping, while fragments of undisturbed, waterlogged habitats have been preserved in what remains of the meandering ancient Žitava River. These refuges are inhabited by various small mammal species and their blood-sucking ectoparasites. Between 2014 and 2018, research on them was carried out in Slovakia’s Danubian Lowland (Podunajská nížina) during three out of the four seasons (spring, summer and autumn). The small mammals were captured at 27 localities. The occurrence of nine flee species from the Hystrichopsyllidae, Ctenophthalmidae and Ceratophyllidae families was documented on 12 small burrowing mammals. During the course of all the seasons in which research was conducted, Ctenophthalmus agyrtes, C. assimilis, Megabothris turbidus a Nosopsyllus fasciatus were found, among the most dominant species to be seen on small burrowing mammals.
