Published: September 2020

Virtualisation is a concept successfully applied to IT systems. In this work, we analyse how virtualisation approaches, such as edge computing, brokerage and software-defined networking, can be applied in the area of electricity grid management and control systems. Power system information and communications technology is currently subject to significant changes. Networked power grid components including renewable energy units, electric vehicles and heat pumps need to be integrated into grid management systems. We studied how virtualisation techniques can support system operators in increasing an energy and communication system’s dependability and situational awareness, and how manual (mostly field-level) configuration and engineering efforts can be reduced. Starting from a working hypothesis, three concrete use-cases were implemented and the performance enhancements were benchmarked to allow for well-informed answers to the questions above. We took a close look at application-protocol-independent redundancy, grid-based routing and online system integrity control. In these study cases, we found significant improvements could be achieved with virtualisation in terms of reduced engineering effort, better system management and simplification in high-level system architecture, since implementation details are hidden by the virtualisation approach.
An Efficient H7 Single-Phase Photovoltaic Grid Connected Inverter for CMC Conceptualization and Mitigation Method
Authors: Mahmoudian Mehrdad , M. G. Rodrigues Eduardo , Pouresmaeil Edris
Published: September 2020

Transformerless inverters are the economic choice as power interfaces between photovoltaic (PV) renewable sources and the power grid. Without galvanic isolation and adequate power convert design, single-phase grid connected inverters may have limited performance due to the presence of a significant common mode ground current by creating safety issues and enhancing the negative impact of harmonics in the grid current. This paper proposes an extended H6 transformerless inverter that uses an additional power switch (H7) to improve common mode leakage current mitigation in a single-phase utility grid. The switch with a diode in series connection aims to make an effective clamp of common mode voltage at the DC link midpoint. The principles of operation of the proposed structure with bipolar sinusoidal pulse width modulation (SPWM) is presented and formulated. Laboratory tests’ performance is detailed and evaluated in comparison with well-known single-phase transformer-less topologies in terms of power conversion efficiency, total harmonic distortion (THD) level, and circuit components number. The studied topology performance evaluation is completed with the inclusion of reactive power compensation functionality verified by a low-power laboratory implementation with 98.02% efficiency and 30.3 mA for the leakage current.
Analysis of Equivalent Diaphragm Vault Structures in Masonry Construction under Horizontal Forces
Authors: Marseglia Pier Silvio , Micelli Francesco , Aiello Maria Antonietta
Published: September 2020

In seismic areas, masonry construction is prone to brittle failures due to the mechanical behavior of the constituent materials and to the low capacity of force redistributions. The redistribution capacity is mainly due to the presence of horizontal connections upon the walls and to the stiffness of the roof, which is typically a vaulted structure. The modeling of the global behavior of a masonry building, taking into account the accurate stiffness of the vaults, is a major issue in seismic design and assessment. The complex geometry of the vaults can be considered as an equivalent plate, able to replicate the stiffness behavior and the force redistribution capacity of the real vault. In this study, the efforts of the authors are addressed to the definition of a plate, able to replace the vaulted surfaces in a global numerical model. The ideal diaphragm is considered as a generally orthotropic plate with the same footprint and the same thickness of the original vault. An extended parametric study was conducted in which the mechanical and geometrical parameters were varied, such as the vault thickness, its dimensions, the constraint conditions, and the possible presence of side walls. The results are presented and discussed herein, with the aim of providing useful information to the researchers and practitioners involved in seismic analyses of historical masonry construction.
Measuring Camellia Petal Color Using a Portable Color Sensor
Authors: Post Phillip , Schlautman Mark
Published: September 2020

The color of petals of flowering plants is often determined by comparing one or more of the petals to various Royal Horticultural Society (RHS) Colour Chart cards until a color match is found. However, these cards are susceptible to fading with age and can also provide inaccurate results if lighting is not optimal. The cards also rely on the human eye to determine a match, which introduces the possibility of human error. The objectives of this study were to determine camellia (Camellia japonica L.) petal color using the RHS Colour Chart, to determine camellia petal color with the NixTM Pro color sensor (Nix Sensor Ltd., Hamilton, Ontario, Canada), and to compare these measurements using different color measuring approaches. Color measurements of camellia flower petals using the NixTM Pro color sensor were compared to published CIELAB values from the Royal Horticultural Society (RHS) Colour Chart. Forty-five petal color samples were collected from fifteen different camellia shrubs. The RHS Colour Chart was used for each of the petals, and the RHS identifications were recorded. Measurements using the NixTM Pro color sensor were compared to RHS-provided CIELAB values that corresponded with the recorded identification for each petal to determine accuracy. The NixTM Pro color sensor’s measurements were also compared to a mean of the values, multiple measurements on the same petal location, and multiple measurements on different petal locations to determine precision and variation. The Nix™ Pro color sensor’s readings were precise in petal color determination and provided more nuanced differences between petals of the same plant and plants of the same variety in each of the color categories. The RHS Colour Chart provided an accurate depiction of most petals, but it was difficult to use with petals that had wide color variation over the entire petal. The Nix™ Pro color sensor’s measurements appeared to have more variation in the b* color space. However, overall, the Nix™ Pro color sensor L*, a*, and b* values were highly correlated with the provided RHS values (p < 0.01), showing that the sensor can be used as an accurate and precise substitute for the RHS Colour Chart. The Nix™ Pro color sensor can be a useful, cost-effective tool to measure the petal color of camellia and other flowering plants and rectifies many of the problems associated with the RHS Colour Chart.

Published: September 2020

Several hepatic steatosis formulae have been validated in various cohorts using ultrasonography. However, none of these studies has been validated in a community-based setting using the gold standard method. Thus, the aim of this study was to externally validate hepatic steatosis formulae in community-based settings using magnetic resonance imaging (MRI). A total of 1301 community-based health checkup subjects who underwent liver fat quantification with MRI were enrolled in this study. Diagnostic performance was assessed using the area under the receiver operating characteristic curve (AUROC). Non-alcoholic fatty liver disease (NAFLD) liver fat score showed the highest diagnostic performance with an AUROC of 0.72, followed by Framingham steatosis index (0.70), hepatic steatosis index (HSI, 0.69), ZJU index (0.69), and fatty liver index (FLI, 0.68). There were considerable gray zones in three fatty liver prediction models using two cutoffs (FLI, 28.9%; HSI, 48.9%; and ZJU index, 53.6%). The diagnostic performance of NAFLD liver fat score for detecting steatosis was comparable to that of ultrasonography. The diagnostic agreement was 72.7% between NAFLD liver fat score and 70.9% between ultrasound and MRI. In conclusion, the NAFLD liver fat score showed the best diagnostic performance for detecting hepatic steatosis. Its diagnostic performance was comparable to that of ultrasonography in a community-based setting.
Advances in Genetic Characterization and Genotype–Phenotype Correlation of Duchenne and Becker Muscular Dystrophy in the Personalized Medicine Era
Authors: Sheikh Omar , Yokota Toshifumi
Published: September 2020

Currently, Duchenne muscular dystrophy (DMD) and the related condition Becker muscular dystrophy (BMD) can be usually diagnosed using physical examination and genetic testing. While BMD features partially functional dystrophin protein due to in-frame mutations, DMD largely features no dystrophin production because of out-of-frame mutations. However, BMD can feature a range of phenotypes from mild to borderline DMD, indicating a complex genotype–phenotype relationship. Despite two mutational hot spots in dystrophin, mutations can arise across the gene. The use of multiplex ligation amplification (MLPA) can easily assess the copy number of all exons, while next-generation sequencing (NGS) can uncover novel or confirm hard-to-detect mutations. Exon-skipping therapy, which targets specific regions of the dystrophin gene based on a patient’s mutation, is an especially prominent example of personalized medicine for DMD. To maximize the benefit of exon-skipping therapies, accurate genetic diagnosis and characterization including genotype–phenotype correlation studies are becoming increasingly important. In this article, we present the recent progress in the collection of mutational data and optimization of exon-skipping therapy for DMD/BMD.

Published: September 2020

One of the prevailing problems for materials produced by powder metallurgy is contamination from various sources. This work deals with the influence of process parameters and presence of process control agents (PCA) on the contamination level of materials produced by means of mechanical alloying (MA) technology, densified with spark plasma sintering (SPS). The equiatomic CoCrFeNi high-entropy alloy (HEA) was manufactured by the said methodology. For clear comparison, the 316L austenitic steel powder was milled and densified with identical conditions as a reference material. Both materials were milled in argon and nitrogen atmospheres for various times from 5 to 30 h. Chemical analysis of contamination by carbon, oxygen, and nitrogen within the powder and bulk materials was carried out using combustion analyzers. The microstructural analysis of powders and bulk samples was carried out using scanning electron microscopy (SEM) with focus on contaminant phases. The results show that carbon contamination increases with milling time. It is caused by wear of milling vial and balls made from high-carbon steels. Increase of carbon content within consolidation using SPS was also observed. The oxygen contamination also increases with milling time. It is more pronounced in the CoCrFeNi alloy due to higher oxidation of powder surfaces prior to milling. Milling of powders using nitrogen atmosphere also causes an increase of nitrogen content in both HEA and AISI 316L. The use of PCA (ethanol) during milling even for a short time (30 min) causes significant increase of carbon and oxygen contamination. The ways to decrease contamination are discussed in the paper.

Published: September 2020

Reductive dehalogenases are responsible for the reductive cleavage of carbon-halogen bonds during organohalide respiration. A variety of mechanisms have been proposed for these cobalamin and [4Fe-4S] containing enzymes, including organocobalt, radical, or cobalt-halide adduct based catalysis. The latter was proposed for the oxygen-tolerant Nitratireductor pacificus pht-3B catabolic reductive dehalogenase (NpRdhA). Here, we present the first substrate bound NpRdhA crystal structures, confirming a direct cobalt–halogen interaction is established and providing a rationale for substrate preference. Product formation is observed in crystallo due to X-ray photoreduction. Protein engineering enables rational alteration of substrate preference, providing a future blue print for the application of this and related enzymes in bioremediation.

Clinical Application and Educational Training for Pharmacogenomics
Authors: Guy Jason W. , Patel Isha , Oestreich Julie H.
Published: September 2020

Pharmacogenomics—defined as the study of how genes affect a person’s response to drugs—is growing in importance for clinical care. Many medications have evidence and drug labeling related to pharmacogenomics and patient care. New evidence supports the use of pharmacogenomics in clinical settings, and genetic testing may optimize medication selection and dosing. Despite these advantages, the integration of pharmacogenomics into clinical decisions remains variable and challenging in certain practice settings. To ensure consistent application across settings, sufficient education amongst current and future healthcare providers is necessary to further integrate pharmacogenomics into routine clinical practice. This review highlights current evidence supporting clinical application of medications with pharmacogenomic labeling. The secondary objective is to review current strategies for educating health professionals and student trainees. One national organization predicts that most regions in the United States will soon contain at least one healthcare system capable of applying pharmacogenomic information. Applying genotype-guided dosing to several FDA-approved medications may help produce beneficial changes in patient outcomes. Identifying best practices for educating health care professionals and trainees remains vitally important for continuing growth of pharmacogenomic services. As pharmacogenomics continues to expand into more areas of healthcare, current and future practitioners must pursue and maintain competence in pharmacogenomics to ensure better outcomes for patients.
The Ethics of Genetic Cognitive Enhancement: Gene Editing or Embryo Selection?
Authors: de Araujo Marcelo
Published: September 2020

Recent research with human embryos, in different parts of the world, has sparked a new debate on the ethics of genetic human enhancement. This debate, however, has mainly focused on gene-editing technologies, especially CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats). Less attention has been given to the prospect of pursuing genetic human enhancement by means of IVF (In Vitro Fertilisation) in conjunction with in vitro gametogenesis, genome-wide association studies, and embryo selection. This article examines the different ethical implications of the quest for cognitive enhancement by means of gene-editing on the one hand, and embryo selection on the other. The article focuses on the ethics of cognitive enhancement by means of embryo selection, as this technology is more likely to become commercially available before cognitive enhancement by means of gene-editing. This article argues that the philosophical debate on the ethics of enhancement should take into consideration public attitudes to research on human genomics and human enhancement technologies. The article discusses, then, some of the recent findings of the SIENNA Project, which in 2019 conducted a survey on public attitudes to human genomics and human enhancement technologies in 11 countries (France, Germany, Greece, the Netherlands, Poland, Spain, Sweden, Brazil, South Africa, South Korea, and United States).

Published: September 2020

Fruit trees need to overcome harsh winter climates to ensure perennially; therefore, they are strongly influenced by environmental stress. In the present study, we focused on the pear homolog PcLEA14 belonging to the unique 5C late embryogenesis abundant (LEA) protein group for which information is limited on fruit trees. PcLEA14 was confirmed to belong to this protein group using phylogenetic tree analysis, and its expression was induced by low-temperature stress. The seasonal fluctuation in its expression was considered to be related to its role in enduring overwinter temperatures, which is particularly important in perennially. Moreover, the function of PcLEA14 in low-temperature stress tolerance was revealed in transgenic Arabidopsis. Subsequently, the pear homolog of dehydration-responsive element-binding protein/C-repeat binding factor1 (DREB1), which is an important transcription factor in low-temperature stress tolerance and is uncharacterized in pear, was analyzed after bioinformatics analysis revealed the presence of DREB cis-regulatory elements in PcLEA14 and the dormancy-related gene, both of which are also expressed during low temperatures. Among the five PcDREBs, PcDREB1A and PcDREB1C exhibited similar expression patterns to PcLEA14 whereas the other PcDREBs were not expressed in winter, suggesting their different physiological roles. Our findings suggest that the low-temperature tolerance mechanism in overwintering trees is associated with group 5C LEA proteins and DREB1.
Biosynthesis and Industrial Production of Androsteroids
Authors: Batth Rituraj , Nicolle Clément , Cuciurean Ilenuta Simina , Simonsen Henrik Toft
Published: September 2020

Steroids are a group of organic compounds that include sex hormones, adrenal cortical hormones, sterols, and phytosterols. In mammals, steroid biosynthesis starts from cholesterol via multiple steps to the final steroid and occurs in the gonads, adrenal glands, and placenta. This highly regulated pathway involves several cytochrome P450, as well as different dehydrogenases and reductases. Steroids in mammals have also been associated with drug production. Steroid pharmaceuticals such as testosterone and progesterone represent the second largest category of marketed medical products. There heterologous production through microbial transformation of phytosterols has gained interest in the last couple of decades. Phytosterols being the plants sterols serve as inexpensive substrates for the production of steroid derivatives. Various genes and biochemical pathways involved in phytosterol degradation have been identified in many Rhodococcus and Mycobacterium species. Apart from an early investigation in mammals, presence of steroids such as androsteroids and progesterone has also been demonstrated in plants. Their main role is linked with growth, development, and reproduction. Even though plants share some chemical features with mammals, the biosynthesis is different, with the first C22 hydroxylation as an example. This is performed by CYP11A1 in mammals and CYP90B1 in plants. Moreover, the entire plant steroid biosynthesis is not fully elucidated. Knowing this pathway could provide new processes for the industrial biotechnological production of steroid hormones in plants.

Published: September 2020

Calcium carbonate (CaCO3) is one of the most important inorganic powders and is widely used as filler in order to reduce costs in the rubber industry. Nanocalcium carbonate reduces costs and acts as a semireinforcing filler that improves the mechanical properties of rubber composites. The objective of this study was to investigate the effect of nano-CaCO3 (NCC) and micro-CaCO3 (MCC) on the properties of natural rubber composites, in particular, new results of structure–properties relationship. The effects of NCC/MCC on the properties of rubber composites, such as Mooney viscosity, bound rubber, Mullins effect, and Payne effect, were investigated. The result of the Mullins effect of rubber composites filled with NCC was in good agreement with the results of Mooney viscosity and bound rubber, with higher Mooney viscosity and bound rubber leading to higher stress to pull the rubber composites. The Payne effect showed that the value of different storage moduli (ΔG’) of rubber composites filled with 25 parts per hundred rubber (phr) NCC was the lowest due to weaker filler network, while the rubber supplemented with 100 phr NCC had more significant ΔG’ values with increase in strain. The results of rubber composites filled with MCC showed the same tendency as those of rubber composites filled with NCC. However, the effect of specific surface area of NCC on the properties of rubber composites was more pronounced than those of rubber composites filled with MCC. Finite element analysis of the mechanical property of rubber composites was in good agreement with the result from the experiment. The master curves of time–temperature superposition presented lower free volume in the composites for higher loading of filler, which would require more relaxation time of rubber molecules. This type of nanocalcium carbonate material can be applied to tailor the properties and processability of rubber products.
Perspectives on Inclusive Education: Need for Muslim Children’s Literature
Authors: Panjwani Antum A.
Published: September 2020

Muslim students and communities in Western sociopolitical and educational contexts confront substantive challenges of racisms, Islamophobia, and under- and misrepresentations in media as well as in literature. Creating a robust repertoire of curricular resources for teaching and learning, teacher development programs, and schooling in general offers a promise of developing classroom practices, which in turn promotes an inclusive discourse that recognizes the unique position and presence of a Muslim child. The present article examines the prospects of developing such a curriculum called Muslim Children’s Literature for inclusive schooling and teacher development programs in the context of public education in Ontario, Canada. It is situated in the larger umbrella of creating specific theory and methodology for education that lend exposure to Muslim cultures and civilizations. Development of such a literature as curricular resources addresses the questions of Muslim identities through curriculum perceptions so as to initiate critical conversations around various educational challenges that the development and dissemination of Muslim curricular resources faces today. I make a case for developing Muslim Children’s Literature to combat the challenges of having limited repertoire to engage with Muslim students in public schools and teacher candidates in teacher development programs. With the description of the necessity of such a literature, this article outlines characteristics of the proposed genre of Muslim Children’s Literature, as well as the unique position of a Muslim child in the current educational scenarios. A brief peek into select fiction on Muslim themes available in English internationally that can be used as curricular resources at elementary and secondary level serves towards reinforcing the definition of Muslim Children’s Literature. Further, these offer a sample that may be promoted under the proposed genre of Muslim Children’s Literature.
Performance and Intrusiveness of Crowdshipping Systems: An Experiment with Commuting Cyclists in The Netherlands
Authors: Lin Xiao , Nishiki Yoshinari , Tavasszy Lóránt A.
Published: September 2020

Crowdshipping systems are receiving increasing attention in both industry and academia. Different aspects of crowdshipping (summarized as platform, supply, and demand) are investigated in research. To date, the mutual influence of crowdshipping platform design and its supply side (with participating crowdshippers) has not yet been thoroughly investigated. This paper addresses this mutual influence by investigating the relations between shipping performance and intrusiveness to daily trips of commuters who voluntarily act as cycle couriers. In an experiment in The Hague, cyclists were asked to transport small parcels during a simulated daily commuting routine. The grid of commuting trips acted as a relay network to move parcels to their individual destinations. All the movements of the parcels were recorded by GPS trackers. The analysis indicates that a higher degree of complexity of rules in crowdshipping systems can lead to better system performance. Meanwhile, it also imposes higher intrusiveness, as participants need to deviate more from their routines of daily, uninterrupted trips. The case also suggests that a well-designed crowdshipping system can increase system performance without having to ask too much from crowdshippers. This study provides reference to better design such systems, and opens up directions for further research that can be used to provide thorough guidelines for the implementation of crowdshipping platforms.
The cultivation of sharptooth catfish (Clarias gariepinus burchell) when the use of compound feed with different protein level
Authors: Vlasov V. , Kulkova I.
Published: September 2020

It has been found as a result of the research that sharptooth catfishes grown on a highprotein diet (the 2nd variant) had a higher growth rate compared to fish that consumed low-protein, but cheap feed (the 1st variant). The average daily gains of fish in the 2nd variant of the experiment corresponded to 6,1 g/day, which was 3,4 g higher compared to the herdmates of the 1st variant. During the experiment period (60 days) the individual weight of catfishes that consumed low-protein compound feed has been increased by 160 g while fish have been grown on high-protein compound feed added 364 g, which was 2,3 times more. In the end the higher yield of fish products per unit of water area has been obtained in the 2nd variant of the experiment 271,2 kg/m[sup]3[/sup] against 118,4 kg/m[sup]3[/sup] in the 1st variant. However, economic analysis has shown that the use of expensive high-protein feed does not give a significant effect. The additional profit in the 1st variant was only 12 %. Catfishes have been grown on high-protein compound feed had the best conformation and technological indicators. They differed from their herdmates from the other variant with higher indicators of edible body parts their body contained less internal fat. High growth and better physiological condition of catfishes that consumed higher-quality protein feed are confirmed by interior, hematological and biochemical indicators. Their blood had a higher concentration of protein, hemoglobin, and fewer white blood cells. In catfishes of the 1st variant the higher level of AST and ALT enzymes has been found in the blood serum, which indicates a low protein metabolism, increased urea synthesis and the high load of work of the liver.
The influence of feed protein not hydrolyzed granules on some indicators when rearing piglets
Authors: Lugovoi M. , Kapitonova E.
Published: September 2020

To date, the technology of obtaining soy protein concentrate using 3D texturing patented in 37 countries consists in the formation of bulk-porous granules with subsequent extraction of low-molecular water-soluble components with clean water, eliminates anti-nutritional factors of carbohydrate, protein and glycosidic nature, and constant laboratory control allows the use of nonadulterated and non-GMO soya. The studies of the infl uence of the effectiveness of granules feed protein concentrated not hydrolyzed (GFPCN) when included in the diets of suckling piglets and weaning piglets on the dynamics of productivity and quality of the resulting products have been presented in the article. Feed protein granules concentrated not hydrolyzed is a new type of soya protein concentrate that does not contain antibiotics, hormones or GMOs. This additive can be added individually to the main diet, as well as to compound feed as the main highly digestible source of protein with the original amino acid composition. The researches have been carried out under industrial conditions of the Unitary Agricultural Enterprise “Raduga-Agro” in the Vetkovsky district in the Gomel region in the Republic of Belarus. In order to conduct these researches, 4 groups of suckling piglets have been formed per 20 heads in each group. The experiment lasted for 90 days. The animals have been selected for the experiments were of the same breed and origin, clinically healthy. Check of productivity indicators of experimental pigs has been carried out at the beginning of the experiment, as well as at 35, 60 and 90 days of age. The results have shown that GFPCN promotes average daily live weight gain of piglets by 2,0–2,7 % more, and to reduce expendutures of feed to get the unit of production by 0,1–0,3 feed units, as well as an additional gross increase in live weight from 8,2 to 14,6 %. At the same time, the study of samples of pig meat from experimental groups has shown that they comply with accepted standards.

The comprehensive evaluation of the productive traits of the initial genotypes of pigs in the creation of breeding herds using population selection methods has been carried out. Based on the results of evaluating the growth and development of breeding animals using the methods of index selection and DNA testing for the genes markers RYR1, ESR, IGF-2, MUC4 the genealogical structure of breeding herds has been formed on the basis of new stud lines of Belarusian stud type of pigs of Yorkshire breed. It has been found that sows of new lines had high reproduction rates: prolifi cacy was 11,6 piglets, milk capacity was 59,1 kg, number of piglets at weaning was 11,2 heads, and litter weight at weaning was 103,6 kg. The breeding herd of two new stud lines is represented by boars of the line Drug 6805 and Dobry 2313. The average productivity of boars-line continuers was: the age of reaching a live weight of 100 kg to 160 days, the average daily gain from birth to reaching the live weight of 100 kg was 636 g. At the age of 12 months, the live weight and body length of replacement boars were 268 kg and 175 cm, the thickness of the fat was 8,9 mm, the height of the longest back muscle was 51,5 mm, the content of lean meat in the body was 62,6 %, which corresponds to the class “elite”. Boars have been separated into reproductive traits. Improvement of lines is carried out through the continuators of related groups. Analysis of genetic studies of animals of new stud lines has shown that they have a high frequency of occurrence of desirable alleles by genes: RYR1 (stress-resistant animals) – 1,0; IGF-2 (fattening and meat traits) – 0,783; ESR (reproductive traits) – 0,608; MUC4 – (resistance to escherichiosis) – 0,786.

Published: September 2020

Anastomosis leakage (AL) after colorectal surgery is an embarrassing problem. It is associated with poor consequence. This review aims to summarize published evidence on prevention of AL after colorectal surgery and provide recommendations according to the Oxford Centre for Evidence-Based Medicine. We conducted bibliographic research on January 15, 2020, of PubMed, Cochrane Library, Embase, Scopus, and Google Scholar. We retained meta-analysis, reviews, and randomized clinical trials. We concluded that mechanical bowel preparation did not reduce AL. It seems that oral antibiotic or oral antibiotic with mechanical bowel preparation could reduce the risk of AL. The surgical approach did not affect the AL rate. The low ligation of the inferior mesenteric artery could reduce the AL rate. The mechanical anastomosis is superior to handsewn anastomosis only in case of right colectomies, with similar results in rectal surgery between the 2 anastomosis techniques. In the case of right colectomies, this anastomosis could be performed intracorporeally or extracorporeally with similar outcomes. The air leak test did not reduce AL. There is no interest of external drainage in colonic surgery but drains reduced the rate of AL and rate of reoperation after low anterior resection. The transanal tube reduced the rate of AL.

Farklı tuz (NaCl) konsantrasyona sahip (%0,3-0,6-0,12) dölleme eriyiklerini gökkuşağı alabalığı (O. mykiss) sperm hareket sürelerine ve dölleme kabiliyetlerine etkisi belirlenmiştir. Kontrol için kullanılan distile saf suda en kısa hareket süresi belirlenirken %0,3 ile %0,12 tuzluluğa sahip solüsyon ile aktive edilen spermlerde sırasıyla sperm hareket süreleri 65 ± 10,01 ve 50,2 ± 3,12 sn olarak belirlenmiştir. En uzun süreli hareket süresi 75 ± 5,17 sn olarak %0,6 tuzluluğa sahip solüsyonla elde edilmiştir. Saf su ile ortalama dölleme oranı 83,76 ± 0,36 olarak belirlenmiştir. Aktivasyon solüsyonlarında ise % 0,3-0,6 ve 0,12 NaCl içeren gruplarda en iyi dölleme oranı % 0,6 konsantrasyona sahip aktivasyon solüsyonu kullanılan grupta gerçekleşmiştir. Dölleme oranları açısından kontrol grubu ve tuzlu dölleme eriyiği kullanılan tüm grupların ortalamaları arasındaki fark istatistiki olarak önemli bulunmuştur (p<0,05).

The fabrics used to manufacture parachutes and paragliders must have several specific characteristics: the mass of
fabric per unit of surface must be low while the other physical-mechanical characteristics (the axial breaking strength
load, the relative and absolute elongation, the tear resistance of the fabric and the assemblies, air permeability) must
have high values. The paper deals with the analysis of qualitative aspects of several parachute fabrics that are used as
a baseline in the development of a novel fabric. The results of experiments have materialized in statistical data, diagrams
and graphs and their interpretation leads to the determination of the fabric variant that best meets the requirements of
the destination. The destination is a patent pending inflatable wing design that utilizes a single skin construction and
solid reinforcements in the sewing for shape stability. It is worth noting that the experimental results were compared with
values indicated in specific international testing norms.

Present generation is fully connected virtually through many sources of social media. In social media, opinions of people for any post, news or about any product through comments or emoticon designed to express the satisfactory note. Market standards improve on this basis. There are different online markets like Amazon, Flipkart, Myntra improve their businesses using these reviews passed. Analyzing large scale opinion or feedback of individual’s helps to identify hidden insights and work towards customer satisfaction. This paper proposes for applying different weighting scheme of TF-IDF (Term Frequency-Inverse Document Frequency) for topic modeling methods LSA and LDA to cluster the topics of discussion from large scale reviews related to booming online market ‘Amazon’. The main focus of the paper is to observe the changes in the topic modeling by applying different weighting schemes of TF-IDF. In this work topic-based models like LDA (Latent Dirichlet Allocation) and LSA (Latent Semantic Allocation) applied to various weighting schemes of TF-IDF and observed the changes of weights leads to variation of term frequency of different topics with respect to its documents. Results also show that the variation of term weights results changes in topic modeling. Visualization results of topic modeling clusters with different TF-IDF weighting schemes are presented.

Flexural, torsional, compressive and shear behavior of Steel Fiber Reinforced Concrete (SFRC) is already studied individually but none has studied the performance of SFRC beams under a combined effect of more than one state i.e. tension, flexure, torsion, compression and shear in general by now. In this study M20 grade of concrete beams under composite behavior of flexure, shear and torsion with different compositions of fibers mix were investigated. The dimensions of specimen beams was 100 mm x 100 mm x 500 mm and straight cylindrical fibers of length 0.28 mm and aspect ratio 100 were mixed. A total of 48 specimen were casted and tested such that for every percentage of fiber and each torsion value three beams were tested. Hence there are four torsion values 0, 61.75, 119.41 and 176.53 N-m are applied (4x3x4=48) It was found during study that ultimate bending stress and deflection increases due to increase in torsion where as the ductility reduced with the torsion enhancement for a specific fraction of fiber content.

Actually, the interference phenomena appear in all current wireless communication systems. Generally, conventional wireless communication systems use two separate channels; one of them for transmitting and the other one for receiving. Achieving single channel full duplex (FD) represents one of the key challenges for the implementation of 5G. Single channel FD permits the capability of wireless communication system to transmit and get concurrently on the identical channel, as well as the assurance of an efficient utilization of the current spectrum. With this newest technology, another sort of interference, which is called self–interference, will be generated. Therefore, self–interference cancellation strategies have an awesome solution for the development of the next generation. Passive and active cancellation techniques can be used to remedy such type of interference. In this regard, a dual feeding antenna approach is regarded as passive cancellation. This paper is concerned with this type of self-interference cancellation. A patch antenna is simulated and tested for two resonance frequencies; 2.45 and 28 GHz. Both of these frequencies are frequency channel candidates proposed by international telecommunication union (ITU) for the fifth generation of mobile networks.

As the coastal line of Tamilnadu is long, it may have been affected due to sea water intrusion by natural (sea level rise) and anthropogenic. Therefore, this study deals with the Hydro chemical assessment of seawater interruption in freshwater aquifer in Parangipettai region. For this assessment, the groundwater samples have been collected in various locations of Parangipettai region for both pre and post-monsoon period. The collected samples were tested by laboratory method for the identification of major cat ions and anions, namely TDS, EC, chloride, magnesium, Bicarbonate, calcium, sodium, potassium, and sulphate. The spatial maps for all the parameters were carried out using the ArcGIS 10.2 version for the purpose of better understanding the quality of groundwater. The results obtained through laboratory method are used to create Salinity and sodium risk of irrigation water in US salinity diagram, Gibbs diagram, permeability index and reconstructed diamond field of piper diagram using the watclast software. From the spatial maps, watclast diagrams and the standards recommended by WHO, BIS, and ISI, the SWI are discussed in detail to recommend the remedial measures to recover and restore the feature of groundwater in the Parangipettai region.
