Authors: Balena Venkataramireddy , Reddy M. R. , Singh Rajendra
Published: October 2018

The present study was intended to investigate the sensitivity of different tissues of tumorous and non-tumorous birds to the polymerize chain reaction-baseddiagnosis of Marek’s disease. Tissue samples were collected from spleen, sciatic nerve, feather follicles and tumour parts (if any)of chickens during the routine necropsy examination. The presence of Marek’s disease virus was examined using primers for 132 bp repeats of BamHI-H regionand positive samples were sequenced for 132 bp repeats and Meq gene. In the birds showing tumours, various samples such as the spleen, feather pulp, sciatic nerve and tumour tissue yielded positive results in 92.31%, 88.46%, 100% and 100% cases respectively. Amongst non-tumorous birds, 11.53% spleen, 23.07% feather pulp and 11.53% sciatic nerve were found positive. This is the first comparative study between nerve and other organs samples for molecular diagnosis of Marek’s disease. Data generated shows that the probability of false negative in tumorous birds and false positive in non-tumorous birds was comparatively low while employing nerve tissue than spleen and feather follicles. Thus, it may be concluded from our study that nerves are a more reliable and robust diagnostic organ in comparison to the other organs used for conventional diagnosis.

Published: October 2018

Cattle are the main source of meat in Chongqing. This study investigated the genetic diversity of cattle native to Chongqing and 4 introduced breeds. A total of 96 individuals from 5 breeds were genotyped using six microsatellite markers. Five markers were highly polymorphic within the breed populations, and one marker had moderate levels of polymorphism. Heterozygosity ranged from 0.5379±0.0434 in Simmental to 0.6667±0.0559 in Charolais. The heterozygosity deficit was significant in all populations analyzed compared with the expected level of heterozygosity. In addition, two microsatellite markers (TGLA53 and OarFCB20) deviated from Hardy-Weinberg equilibrium across populations (except in cattle native to Chongqing). The mean number of alleles ranged from 6.00±2.37 in Angus to 7.17±2.14 in Droughtmaster across six markers. The coefficient of inbreeding ranged from 0.0017 in Simmental and Droughtmaster to 0.0367 in Angus. Pairwise difference analyses revealed that Simmental and Droughtmaster were the most differentiated (FST= 0.06861) from each other, whereas cattle native to Chongqing and Charolais were the least differentiated (FST= 0.00557). In summary, this study showed that cattle native to Chongqing and 4 introduced breeds were genetically well protected in Chongqing, and information from this study would be helpful for guiding hybridization and genetic improvements in the future.

Published: October 2018

The investigation aimed to study the effect of vegetable oil sources on feed intake, nutrient digestibility and biohydrogenation bacterial population in Thai Friesian dairy cows. Three fistula Thai Friesian cows with mean body weight (BW) of 600±100 kg were assigned to receive three vegetable oil sources i.e. palm oil (PO), soybean oil (SBO) and sunflower oil (SFO) included at 4 %DM in commercial concentrate. All cows were fed on different diets that contained concentrate of 1 %BW and rice straw of 1 %BW according to a 3×3 latin square design (LSD). The results revealed that dry matter digestibility (DMD) and organic matter digestibility (OMD) tended to be higher in cows fed on SBO and SFO (P=0.06). Moreover, the DNA copy numbers (copies/ml) of biohydrogenation bacteria (Ruminococcus albus) and cellulolytic bacteria (Ruminococcus flavefaciens and Prevotella ruminicola) were higher in cows fed on SBO (P less than 0.05). In summary, supplementation of SBO in diet resulted in a higher nutrient digestibility and rumen biohydrogenation bacteria population.

Published: October 2018

This study was conducted to evaluate the effect of choline chloride alone and in combination with propylene glycol on the growth performance, meat quality and backfat in finishing pigs. A total of 90 crossbred ((Landrace× Yorkshire)× Duroc) pigs with an average initial body weight (BW) of 75.15± 1.94 kg were randomly distributed by BW and sex. This 8-week experiment consisted of 3 dietary treatments with 6 replications per treatment and 5 pigs per pen. The experiment included 3 treatments: CON, basic diet; TRT1, basic diet+0.05% choline chloride; TRT2, basic diet+0.05% biocholine P (chloride chloride and propylene glycol). Body weight was statistically higher (P less than 0.05) in pigs fed TRT2 diet than the CON diet in week 8. During 4 to 8 weeks and overall, the average daily gain (ADG) was significant higher (P less than 0.05) in the pigs fed TRT2 diet than the CON diet. Digestibility of nitrogen was significantly increased (P less than 0.05) at week 4 and week 8, back fat was higher (P less than 0.05) in week 6 and week 8 in pigs fed TRT2 diet than the CON diet. In conclusion, dietary TRT2 can increase the BW, ADG, nitrogen, and backfat in finishing pigs.

Published: October 2018

A greenhouse experiment was conducted to investigate the effect of different levels of NaCl salt on tomato upon B. cinerea infection the causal agent of gray mold disease. The disease assessment was recorded after inoculation by using the scale based on percentage leaf area affected, and the growth of the plants was recorded for each treatment. Three weeks after inoculation by conidial suspension, the estimated disease severity on plants of tomato was 35.18% compared to the control. The highest incidence disease increase of gray mold (39.21%) was obtained with using 300 mM of NaCl after inoculation with B. cinerea compared with the other concentrations and as well as distilled water. Under severe salt stress (150 and 300mM) increased susceptibility of gray mold disease severity were observed in plants inoculated with B. cinerea, while under mild salt stress (50mM of NaCl) this effect was reversed. The treatment of plant by B.cinerea has reduced the growth of the aerial part of tomato plants (39.06%) after three weeks inoculation compared to the control. Three levels of NaCl (50, 100 and 150mM) increased respectively the plant height from 12.73 to 29.84%, 0.28 to 27.16% for the fresh eight and 5.75 to 33.35% for dry weight compared to the plants inoculated and irrigated by distilled water. NaCl addition at 300mM on plants inoculated with B. cinerea decreased the height, fresh weight and dry weight at 0.99, 4.45 and 11.01% respectively.

Authors: Devi R. , Mittal R. K. , Sood V. K. , Sharma P. N.
Published: October 2018

The main objective of this study was to assess the genetic diversity of 34 genotypes comprising of 25 advanced derivatives of interspecific cross between V. mungo x V. umbellata, five intervarietal crosses along with four checks (including blackgram parents) using 11 morphological traits and molecular markers (RAPD and ISSR) and for their resistance towards Cercospora, anthracnose and MYMV. The lines Palampur-93 x BRS-1 (236-A-L-1-4), HPBU-35 and HPBU-111 were found statistically at par to the best check Him Mash-1 for seed yield. Correlation studies revealed that the selection should be based on large seeds, more number of pods per plant and more number of seeds per pod indicating the importance of these traits in yield determination. The cluster analysis on molecular basis grouped the blackgram parents and advance lines differently than at morphological level which revealed genetic variation among genotypes and also confirmed that rigorous selection had been made for blackgram types in segregating generations rather than ricebean types as most of the advance derivatives of V. mungo x V. umbellata were found to be concentrated near blackgram parents. The lines PDU-1 x PRR-1 (62-3-L-10-1) and Palampur-93 x PRR-1 (258-1L-2-5) were found resistant to both Cercospora and anthracnose while, Palampur-93 x BRS-1 (236-A-L-3-2) for MYMV. The information generated from this study would be helpful in characterizing the advanced derived lines and parents in the selection and utilization of diverse genotypes to enhance variability and productivity along with resistance breeding of V. mungo.

The Extent and Gender Directionality of Intimate Partner Violence in Different Relationship Types: A Systematic Review and Meta-Analysis
Authors: Rozmann Nir , Ariel Barak
Published: October 2018

The domestic violence research indicates two different approaches to victims. On one hand, it is argued that violence is a masculine or patriarchal mechanism of control and superiority based on research that shows higher rates of male violence toward women than vice versa. On the other hand, there is ample research that supports the claim of those patterns of violence and rates of victimization are equal between the genders. These contradictory findings call for a systematic review and a meta-analysis of the empirical data in order to establish the extent and directionality of victimization and abuse in violent relationships. To provide a more nuanced overview of this phenomenon, the present review examines the frequency of physical violence in different types of heterosexual relationships—dating, cohabitation, and marriage—according to national surveys and victim self-reports. The analysis is limited to sources in Hebrew and English. The searching procedure and criteria applied in selecting the studies generated 55 published studies from 36 countries. The main conclusion of the review is that the extent and directionality of violence vary with the type of relationship: while dating was reported to have higher rates of male victimization, in cohabitation and marital relationships, females reported higher levels of victimization rather. This article addresses the theoretical and practical implications of these findings.

Triamine-bearing activated rice husk ash as an advanced functional material for nitrate removal from aqueous solution
Authors: Phan Phuoc Toan , Nguyen Trung Thanh , Nguyen Nhat Huy , Padungthon Surapol
Published: October 2018

In this study, we proposed a simple method for preparing triamine-bearing activated rice husk ash material (TRI-ARHA) as an advanced functional material with high nitrate adsorption capacity and durability. The novel TRI-ARHA was generated via a post-synthesis grafting method and modified by acidification to form ammonium moiety. TRI-ARHA was then characterized by using thermogravimetric analysis, Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy and SEM-mapping. The TRI-ARHA had high nitrate adsorption capacity of 163.4 mgNO3−/g, which was 2.06 times higher than that of a commercial anion exchange resin (Akualite A420) due to strong interactions of Si, C, and N in the material structure. This functional material with good durability after 10 cycles could be very promising for adsorption of other anions (e.g. sulfate and phosphate) in water and wastewater treatment.

Authors: Kai Tao , Xiaoyun Sun , Yang Wang , Li Jingchun
Published: October 2018

Background:

As the multimedia service develops and the transmission rate in terrestrial
communication systems increases rapidly, satellite communication needs to improve the transmission
rate and throughput. Multiple Input Multiple Output (MIMO) techniques can increase the system
capacity significantly by introducing the space dimension, as the system bandwidth remains the
same. Therefore, utilization of MIMO for satellite communications to increase the capacity is an important
research topic. So MIMO techniques for multibeam satellite communications are researched
in the dissertation.

Objective:

The goal of this work is improving the capacity of the satellite system. Multi-beam and
dual-polarized technologies are applied to a satellite system to improve the capacity further.

Methods:

In this paper, we first introduce a multi-beam dual-polarized satellite multi-put and multiout
(MBDP-S-MIMO) system which combines the full frequency multiplexing and dual-polarization
technologies. Then the system model and channel model are first constructed. At last, to improve the
capacity further, BD and BD-ZF precoding algorithms are applied to MBDP-S-MIMO and their performance
is verified by simulation.

Results:

Simulation results show the performance of the BD precoding algorithm gets better with the
growth of the XPD at the receiver and is almost not affected by the growth of the channel polarization
correlation coefficient. In addition, with the growth of the users’ speed, the performance becomes
worse.

Conclusion:

The multi-beam dual-polarized satellite MIMO system has high capacity, and it has
certain application prospects for satellite communication.
Characteristics of Violations in the Aggregate State of Blood Regulation System of Women with a High Degree Anemia on the Background of Endometrium Hyperplastic Processes
Authors: Byrchak Inna
Published: October 2018

Endometrial hyperplasia is a benign pathology of the uterine mucosa, characterized by certain histological changes, characterized as simple and complex, non-atypical and atypical forms. Hyperplastic processes of endometrium, according to various authors, in the structure of gynecological pathology make up 15 to 40%. Clinically, the endometrial hyperplasia manifest by uterine bleeding. Maternal bleeding that is not susceptible to hormonal, symptomatic, and hemostatic therapy, leads to chronic post-hemorrhagic anemia and is the indication for surgical intervention. Consequently, systemic disorders of the hemostasis parameters on the background of uterine bleeding with endometrial hyperplasia, in particular the regulation of the aggregate state of blood systems, require further research to identify new pathogenetic links and develop correction methods.Materials and methods.State of platelet-vascular hemostasis was assessed by the percentage of platelets adhesion in the blood and by the index of spontaneous platelet aggregation. Total potential coagulation of blood, plasma fibrinolytic activity, plasminogen potential activity, antiplasmin, fibrinogen in blood plasma, the activity of antithrombin III, the concentration of soluble fibrin monomer complexes in the blood was determined by reagents made by Simko Ltd company (Ukraine). Using the «Thromboelastohraph ACG» machine we identified parameters of thrombin clotting rate, thromboelastograph K constant, specific platelets convolution constants, a- angle and coagulation composite index.Results. In women with anemia of ІІІ-rd degree against background of the uterine bleeding, at high activity of primary hemostasis, structural and chronometric hypocoagulation develops; it is predefined by the acute decreasing of fibrinogen in the blood. The principal reason of hypofibrinogenaemia is the excessive activating of non-fermentative fibrinolysis. In conclusion, changes in the system of regulation of the aggregate state of blood in women with severe degree of anemia are the display of subclinical inopexia that develops as a result of thrombocytes high functional activity.

Published: October 2018

Рассматривается проектирование антенны в виде горизонтально расположенного широкополосного полуволнового вибратора с зонтичным отражателем, создающего направленное вверх излучение. Для работы в широком частотном диапазоне 230…280 МГц рассмотрены варианты согласующих устройств. Компьютерное моделирование антенны в программном пакете MMANA-Gal показало достаточную для практики нечувствительность к условиям размещения антенны относительно земли. Для синтеза согласующего устройства в программном пакете RFSim99 был построен антенный эквивалент, имеющий близкое к антенне входное сопротивление во всем частотном диапазоне 230…280 МГц. Среди вариантов пассивного согласования антенны с фидерным трактом были рассмотрены широкополосные трансформаторы сопротивлений с коэффициентами 1:2 (идеальный) и 1:2,5 (физически реализованный), а также согласующее устройство на реактивных элементах. Эффективность широкополосного согласования оценивалась качественно по диаграмме Смита в программе RFSim99, а также количественно через расчет коэффициента стоячей волны (КСВ) и коэффициента отражения в частотном диапазоне 230…280 МГц. Исследование эффективности вариантов широкополосного согласования на фидерную линию 50 Ом показано, что результаты согласования трансформаторами 1:2 и 1:2,5 существенно не отличались, обеспечивая КСВ £ 2. В то же время согласование на реактивных элементах позволило достичь КСВ £ 1,5. Выполненное моделирование продемонстрировало высокие эксплуатационные характеристики широкополосной антенны с зонтичным отражателем в диапазоне частот 230…280 МГц, достигаемые с применением предложенных схем широкополосных согласующих устройств.

The Mathematics students who perform truth-seeking process upon solving mathematical problems were unique. Therefore, the study deems it necessary to know students’ mental structure and mechanism so that they can make the right decision by performing truth-seeking. However, no research has delved into the mental structures and mechanisms of Mathematics students, who tend to grapple with truth-seeking processes extensively. This study was explorative qualitative because the aims to describe the types of mental structure and mechanism of Mathematics students upon the truth-seeking process in solving mathematical problems. The research subjects are four Mathematics students at the University of Jember who perform truth-seeking and can communicate fluently when performing think-aloud. Their responses in the answer sheets drove the determination of research subjects' tendency in truth-seeking. Afterward, the results of think-aloud and task-based interview were put under analysis, so as to determine the types of mental structure and mechanism. The research findings have indicated that (1) all mental structures have been constructed by all research subjects and (2) two types of mental mechanism are evident among the subjects, including the process of interiorization coupled with coordination and another process encompassing interiorization, coordination, and reversal.

The geometry in flipbook multimedia can improve the necessary skills of the 6th graders, so that achieve the highest level of geometric thinking that is informal deductive. The flipbook which uses technology with flipping experience, animation, video, and music is different than the ordinary printed book. Also, it looks more exciting and interactive for students. The aim of this research measures flipbook effectiveness on limited-scale and wide-scale tryout, it is reviewed from Skill Gist Competence domain (KI-4) of Curriculum 2013 on geometry primary skill indicator, also examining flipbook efficacy if it is compared with the printed book which has been used before. The instrument used on a limited-scale tryout and wide-scale tryout is a rubric assessment of product-based and performance-based. However, the tool used on the efficacy test is an achievement test which consists of twenty questions of multiple choice. The test material in the achievement test is about quadrilateral and problem-solving. Based on statistic analysis result on the efficacy test, the research result shows that student’s capability who uses flipbook is better than the student who doesn’t, in learning geometry. Furthermore, the conclusion is that flipbook multimedia is more efficacy than before product.

La Enfermedad de Parkinson (EP) es un desorden neurodegenerativo del sistema nervioso central, cuyas características principales incluyen entre otras la rigidez, bradicinesia y pérdida de los reflejos posturales. El diagnóstico de la EP está basado en análisis de la historia clínica y evaluaciones físicas realizadas a los pacientes. El monitoreo del estado neurológico de los pacientes está basado en valoraciones subjetivas que realizan los neurólogos. El análisis de la marcha usando sensores inerciales aparece como un instrumento sencillo y útil para ayudar en el proceso de diagnóstico y monitoreo de los pacientes con EP. En este artículo usamos el sistema eGaIT, el cual captura señales de acelerómetro y giróscopo del proceso de marcha para evaluar las habilidades motoras de los pacientes. Las transformadas de Fourier y Wavelet son utilizadas para extraer medidas basadas en energía y entropía en el dominio de Tiempo-Frecuencia. Las características extraídas son utilizadas para discriminar entre pacientes con EP y personas sanas. De acuerdo con los resultados, es posible clasificar estos dos grupos con una precisión de hasta el 94 %.

Published: October 2018

Ta2O5 is a wide-bandgap semiconductor that offers interesting applications in microwavecommunications, mainly related to the manufacture of filters and resonators whosesize is inversely proportional to the dielectric constant of the material. For that reason, inthis work we present a theoretical study, based on density functional theory (using PBEsoland hybrid HSE06 exchange-correlation functionals), of the electronic and dielectricproperties of the orthorhombic model -Ta2O5. We found that this model has a direct gap of2.09 and 3.7 eV with PBEsol and HSE06, respectively. Furthermore, the calculated staticdielectric constant, 51, is in good agreement with the reported values of other phases of thissemiconductor.

Background/Aim. Breast cancer comprises about 25% of all female cancers, and its incidence is increasing. New diagnostic procedures and therapeutic modalities have increased treatment success rates as well as patient survival. The goal of contemporary treatment is not only patient survival, but also a better quality of life (QoL). The objective of this study was to assess the effect of age at diagnosis on the QoL of patients with breast cancer before and after surgery. Methods. We analyzed QoL in 170 female patients (43 patients < 50 and 127 patients ? 50 years) diagnosed with breast cancer (I and II stage) a month before and after surgical treatment, using the European Organisation for Research and Treatment of Cancer (EORTC QLQ-C30) questionnaire and specific version for breast cancer patients (EORTC QLQ-BR23). Results. The QLQ-C30 questionnaire showed that surgical treatment significantly decreased all domains of the patients? QoL in both age groups. Agerelated differences were present in sexual functioning and pleasure independently of surgical treatment, with higher scores in the group of younger women. The analysis of data obtained using the QLQ-BR23 questionnaire revealed a lower QoL after surgical treatment in almost all dimensions regardless of patients? age. Conclusion. The results of our study pointed out statistically significant differences in the QoL domains of sexual functioning, and sexual enjoyment between women in both age groups independently of surgical treatment. The QoL was better in the younger age group. Surgical breast cancer treatment negatively affected patients QoL independently of age.
