Ефективність застосування альфасорбу у годівлі поросят

Mycotoxins cause severe diseases in organisms of human and animals. They are difficult to diagnose, cause great economic damage. Sorbents are able to effectively bind and remove from the body through the digestive tract with a therapeutic or prophylactic purpose various endogenous and ekzogenous substances, microorganisms and they toxins, supermolecular structures and cells. The aim of the work is to study the effectiveness of use of Alfasorb for the neutralization of mixed fodders affected by mycotoxins and they impact on blood’s indexes and productive qualities of piglets of Large White Breed. Experience was conducted on 30 ty piglets. Animals of the control group received mixed feed that was produced in the conditions of the farm. The pigs of experimental group in addition to the basic diet received Alfasorb. We determined blood’s indexes for study the effect of feed additive Alfasorb on the physiological state of animals at 4 months of age. A morphological and histological study of liver was carried out. The analysis of the average daily weight gain of piglets showed that it was higher in period of growth in the animals of experimental group. In the animals of the experimental groups there was an increase in the number of red blood cells in comparison with the control. An unreliable decrease in blood serum levels which characterize the level of intermediate metabolism of proteins in the body (content of urea, creatinine and common bilirubin) was established in the animals of the experimental group as compared to the control group respectively by 22.83% ( td = 0.98, P ≤ 0.05), 7.12% (td = 1.92, P ≤ 0.05) and by 20.54% (td = 0.86, P ≤ 0.05). Most hepatocytes had large nucleus and intense color of the cytoplasm. This indicates the absence of alterative processes in the body. The results of the studies make it possible to assert that the inclusion the 0.2% Alfasorb to the compound of feed which contaminated with mycotoxins significantly reduces their negative effect on the piglets organism, has a positive effect on the growth rate, on the course of metabolic processes, also it promotes an increase in the liver of medium-sized hepatocyte nuclei, stimulates biosynthetic processes in that cells and ensures the formation of a full structure of histohematological barriers in the organism.Мікотоксини спричиняють різні захворювання в організмі людини та тварин. Вони важко діагностуються та призводять до великих економічних збитків. Сорбенти здатні ефективно зв’язувати та виводити з організму через травний тракт з профілактичною чи терапевтичною метою різні ендогенні та екзогенні субстанції, мікроорганізми та їх токсини, складні молекулярні структури та клітини. Мета роботи – дослідити ефективність застосування альфасорбу для нейтралізації комбікормів, уражених мікотоксинами, та їх вплив на показники крові та продуктивні якості поросят великої білої породи. Дослід проводили на 30-ти поросятах. Тварини контрольної групи отримували комбікорм, що виробляється в умовах ферми. Поросята дослідної групи у додаток до основного раціону одержували альфасорб. Ми вивчали показники крові для визначення впливу кормової добавки альфасорб та фізіологічний стан тварин 4-місячного віку. Було проведено морфологічне і гістологічне дослідження печінки. Аналіз середньодобових приростів поросят показав, що вони були більшими у період росту тварин експериментальної групи. У тварин дослідної групи була більшою кількість еритроцитів, у порівнянні з контролем. Встановлено зниження у сироватці крові тварин дослідної групи показників, що характеризують проміжний обмін (вміст сечовини, креатиніну та загального білірубіну), у порівнянні з контрольною групою відповідно 22,83% (td = 0,98, P ≤ 0,05), 7,12% (td = 1,92, P ≤ 0,05) and by 20,54% (td = 0,86, P ≤ 0,05). Більшість гепатоцитів мали великі ядра та інтенсивне забарвлення цитоплазми. Це вказує на відсутність альтеративних процесів в організмі. Результати досліджень дозволяють зробити висновок, що включення 0,2% альфасорбу до складу корму, контамінованого мікотоксинами, значно зменшує їх негативний вплив на організм поросят, позитивно впливає на прирости, перебіг метаболічних процесів, також сприяє, зниженню у печінці середніх розмірів ядер гепатоцитів, стимулює біосинтетичні процеси у цих клітинах та забезпечує формування повної структури гістогематологічних бар’єрів у організмі

QDB: A new database of plasma chemistries and reactions

One of the most challenging and recurring problems when modeling plasmas is the lack of data on the key atomic and molecular reactions that drive plasma processes. Even when there are data for some reactions, complete and validated datasets of chemistries are rarely available. This hinders research on plasma processes and curbs development of industrial applications. The QDB project aims to address this problem by providing a platform for provision, exchange, and validation of chemistry datasets. A new data model developed for QDB is presented. QDB collates published data on both electron scattering and heavy-particle reactions. These data are formed into reaction sets, which are then validated against experimental data where possible. This process produces both complete chemistry sets and identifies key reactions that are currently unreported in the literature. Gaps in the datasets can be filled using established theoretical methods. Initial validated chemistry sets for SF 6 /CF 4 /O 2 and SF 6 /CF 4 /N 2 /H 2 are presented as examples

METHODOLOGY OF JUSTIFICATION THE TYPE AND EVALUATION OF QUALITY GROUP SEARCH OF DEFECTS IN THE REPAIR RADIO-ELECTRONIC MEANS

Context. Radioelectronic devices are continuously complicated, which complicates the process of restoring their efficiency, when the diagnosis consumes the largest labor costs and time. Therefore, the promising direction of increasing the efficiency of the renewal of modern electronic means is to improve diagnostic support.Objective. The purpose of the article is to increase the efficiency of diagnostic provision of radio electronic means at the expense of a reasonable choice of the type of group search of defects.Method. In the work analytical studies of conditional algorithms of diagnosis with the use of graph theory theory, probability theory and the theory of discrete search – a scientific discipline that studies the diagnostic process when restoring the efficiency of complex technical objects with varying degrees of damage through research and optimization of procedures and algorithms for detection of a priori – in unknown number of elements with given properties on the finite structurally-bounded set according to some criterion.Results. The method of choosing the type of algorithm of group search of defects at given restrictions and assumptions on the criterion of minimum labor costs on the basis of generalization of the graph-analytical model of group search of defects with quantitative estimation of probabilistic, time and cost indicators of the quality of the process of diagnosing radioelectronic devices with different degree of damage, which allows to pre-substantiate the most appropriate algorithm for group defects search for use in the development of diagnostic support for modern radio ectronic means.Conclusions. For the first time, various types of group search of defects with a quantitative estimation of the efficiency of their use depending on the features of radio-electronic means and the conditions for their restoration of efficiency are considered in a complex way

R-matrix calculation of low-energy electron collisions with LiH

Calculations are performed for electron scattering from LiH. These show that use of a close-coupled expansion gives results significantly different from calculations performed at the static exchange level employed in all previous calculations. In particular the close-coupled calculations find a Feshbach resonance which follows the first excited, a3Σ−, state curve. This resonance could provide a route to dissociative attachment and electron impact vibrational excitation. Elastic scattering cross sections, which are very large, as well as inelastic cross sections for excitation to the four lowest electronically excited states are presented as a function of LiH bond length

Threats to feminist identity and reactions to gender based discrimination

The aim of this research was to examine conditions that modify feminists’support for women as targets of gender discrimination. In an experimental study we tested a hypothesis that threatened feminist identity will lead to greater differentiation between feminists and conservative women as victims of discrimination and, in turn, a decrease in support for non-feminist victims. The study was conducted among 96 young Polish female professionals and graduate students from Gender Studies programs in Warsaw who self-identified as feminists (Mage=22.23). Participants were presented with a case of workplace gender discrimination. Threat to feminist identity and worldview of the discrimination victim (feminist vs. conservative) were varied between research conditions. Results indicate that identity threat caused feminists to show conditional reactions to discrimination. Under identity threat, feminists perceived the situation as less discriminatory when the target held conservative views on gender relations than when the target was presented as feminist. This effect was not observed under conditions of no threat. Moreover, feminists showed an increase in compassion for the victim when she was portrayed as a feminist compared to when she was portrayed as conservative. Implications for the feminist movement are discussed
