The crucial problem of ensuring operational reliability of modern radio electronic equipment is the problem of detecting the integrated circuits with latent (not obvious) defects in the course of production. Such defects shall not be revealed through standard checking procedures specified in standard normative technical documentation.Важнейшей проблемой обеспечения эксплуатационной надежности современной радиоэлектронной аппаратуры является проблема обнаружения в процессе производства интегральных схем, имеющих скрытые (неявные) дефекты. Такие дефекты не выявляются обычными видами контроля, заложенными в нормативной технической документации

Problem-solving tasks in studying agrarian question of history of Kazakhstan

© 2017 Serials Publications.The relevance of the article is to show the problem method of training and a possibility of its application by means of introduction in process of training at lessons of history of Kazakhstan of problem and informative tasks is considered. The purpose, types and stages of work of this technology are defined. Concrete examples of tasks for pupils of 8 classes as the problem of agrarian crisis in the territory of Kazakhstan during his stay as a part of the Russian Empire is subject to consideration (the end of XIX - the beginning of the 20th centuries) are given that corresponds to program material of this age category. The importance of application of the methods aimed at independent search of knowledge and more expanded comprehension of knowledge of pupils reveals. The statå stage of experiment where the initial level of knowledge of pupils reveals is shown in article and the importance of application of problem tasks at further stages of work is proved, questions for questioning at identification of initial knowledge of a subject, and also direct steps in work on drawing up and application of similar tasks are offered. Article Submissions are of practical value for children. having entered life, the child will be more protected from stresses. Problem training forms harmoniously developed creative person capable to think logically, find solutions in various problem situations, capable to systematize and accumulate knowledge, capable to high introspection, self-development itself also corrections. Continuous setting of problem situations leads to the loss of fear by a child to face problems, a child seeks ways to resolve them, and the creative personality, always capable to search is formed

Whole-genome association studies of distribution of developmental abnormalities and other breeding-valuable qualitative traits in offspring of the Russian large-white boars

Identifying genome regions that are directly or indirectly associated with developmental defects and malformations in domesticated pigs can help identify genomic traits used as biomarkers of the structural and functional composition of the body, their metabolic status and genetic diseases as well. Such studies are directly related to the improvement of the economic efficiency, as they allow identification and exclusion of defect animals, who may carry target genes not appearing phenotypically, from the breeding process. In the current work, we have searched for these kind of target genes and genome regions with conducting the genome-wide association studies using PorcineSNP60K BeadChips (Illumina, San Diego, USA). A total of 48 boars of a large white breed of the nucleus farm “Znamenskoe” were analyzed for 21 traits of indicated shortcomings of the exterior and defects of development in 39,153 their offspring.  Calculations were made using a mixed type linear model in package GEMMA. In this study, we selected only 36,704 polymorphic SNPs from an initial 61,000-strong SNP set. After GWAS, we obtained 24 alleles in 11 corresponding genes  (P < 0.1) in the genome of pigs, which are significantly correlated with traits of developmental abnormalities such as anal atresia (ARMC7,FANCC,RND3,ENSSSCG00000017216), limb problems (PAWR,NTM,OPCML,ENSSSCG00000040250, ENSSSCG00000017018) and tremor of piglets (RIC3,ENSSSCG00000032665). Also, co-expression of the NTM,OPCMLand  RND3genes was revealed. This study confirms the relevance of using the single SNP detection according to the single trait approach in associative studies, even for small sample numbers

ЭФФЕКТИВНЫЙ СПОСОБ ВЫЯВЛЕНИЯ НЕНАДЕЖНЫХ КМОП СХЕМ

With increase of complexity factor of integrated circuits and reduction of the geometrical dimensions of integrated structures and detection of unreliable circuits still remains an actual problem. A method of rejection of potentially unreliable circuits most often used in production is imitation of operational modes at a stage of tests. However complexity and duration of realization of the specified method does it practically not suitable in the conditions of mass production of integrated circuits.С увеличением степени интеграции интегральных схем, уменьшением геометрических размеров интегральных структур выявление ненадежных схем по-прежнему остается актуальной задачей. Наиболее часто используемый в производстве метод отбраковки потенциально ненадежных схем - имитация эксплуатационных режимов на этапе испытаний. Однако сложность и длительность реализации указанного метода делает его практически не пригодным в условиях массового производства интегральных схем

Influences of technologies of cultivation of perennial bluegrass herbs on their transpiration in the conditions of water meadows

This article discusses the process of transpiration in perennial herb crops in the southwest of Bryansk region (Russia) under different technologies of cultivation, using superficial and radical improvement of natural fodder conditions. Experimental field surveys were conducted on the flood plain of the river Iput in 2009–2014. These years were characterized by different phytoclimatic conditions. The amounts of daily values of radiation balance for the period of vegetation in 2010, 2012, 2013, 2014 constituted respectively 1127, 1126, 1181, 1157 MDzh/m2 whereas during 2009 and 2011 respectively they came to 963 and 915 MDzh/m2. The maximum daily values for photosynthetically active radiation (PAR) were observed in 2012 and 2013 and constituted respectively 764 and 710 MDzh/m2, the minimum – in 2009 and 2011 – constituted respectively 635 and 592 MDzh/m2. During the vegetation period from the first hay crop to the second higher values of radiation balance and PAR were observed than during the period up to the first hay crop. Despite differences in the productivity between different variants of the cultures, a directly proportional linear dependence between productivity and transpiration with a high coefficient of correlation was obtained for every year of the research and stage of the hay crop. The transpiration coefficient for bluegrass herbs which are grown in river flood plains is established for the first time. The transpiraton coefficient doesn’t depend on the type of dose and ratio between different fertilizers, nor on the method of preparing the soil. The transpiration coefficient of crops of bluegrass herbs doesn’t depend on doses and a type of the introduced fertilizers, the method of handling of the soil, and for the first and second hay crops respectively constituted 469 and 486 per dry weight. The increase in transpirational consumption of moisture in dry weight formation during the period from the first hay crop to the second was caused by decrease in bioavailability of moisture during this period. We established that the crops of bluegrass herbs cultivated on alluvial sandy soil without use of mineral fertilizers don’t use the moisture which is accumulated during the autumn and winter and spring period, and the crops of bluegrass herbs cultivated using mineral fertilizers lack moisture during the vegetation period from first to the second hay crop only in drought years. We have experimentally proved that mineral fertilizers raise the relative transpiration and bioavailability of soil moisture to plants. It is suggested that the soluble salts which are a component of fertilizers increase osmotic pressure in the vascular system of plants. It was proved that preseeding working of the soil with a turnover of the layer at a depth of 20 cm increases bioavailability of soil moisture and absorption of solar radiation during the vegetation period in drought years
