Tenderness, together with flavour, is the main quality trait that defines consumer acceptance of sheep meat. The factors affecting tenderness can be grouped as those influenced before slaughter, in the early post-mortem intervention and, finally, during the aging period. These factors have been extensively studied with respect to tenderness, but the impact of early post-mortem interventions and subsequent aging on the microbial quality of the final products has not been broadly reviewed to date. In this review, the authors summarize the most recent knowledge on lamb meat tenderness management and how such practices may impact the final meat quality, especially its microbial status. The impacts of pre-slaughter factors (age, sex, diet, genotype and transport) and post-mortem interventions (chilling regime, electrical stimulation, or hanging method), are described and comprehensively discussed.

Oriented strand board (OSB) is a commonly used structural wood-based panel for walls and roof siding, but recently the industry has become interested in OSB as a substrate for indoor and outdoor furniture. Particleboard is mainly used in furniture productions and has become popular as a construction material due to its numerous usage possibilities and inexpensive cost. Moisture is one of the most important factors affecting wood-based panel performance and the post-treatment conditions affected their affinity to water. When OSB and particleboard are used as substrates for coatings, their surface characteristics play an important role in determining the quality of the final product. Furthermore, roughness can significantly affect the interfacial phenomena such as adsorption, wetting, and adhesion which may have an impact on the coating performance. In this research particleboard and OSB panels were sanded, re-pressed and IR heated and the influence of surface treatments on hardness, roughness, wetting, water, and water vapour absorption was studied. Results showed that sanding improved the wetting of particleboard and OSB with water. Moreover, studied surface treatments increased water absorption and water penetration depth of OSB panels, and re-pressing had a positive effect on reducing the water vapour absorption of particleboard and OSB panels.

Актуальность статьи связана с поиском новых способов и методов повышения эффективности борьбы с преступностью, оперативного раскрытия преступлений, а также с набирающим популярность среди криминалистов направлением «криминалистического мышления», овладение навыками которого будет способствовать наиболее полноценному и объективному расследованию уголовных дел. Проблемным в настоящее время является недостаточное качество следствия и необходимость повышения когнитивных способностей следователей (дознавателей). Задачей исследования являлось выявление факторов, влияющих на развитие и формирование криминалистического мышления следователей. Цель работы - провести анализ составных частей процесса становления следователя и особенностей его практической деятельности, влияющих на когнитивные способности с точки зрения криминалистики, путем изучения и сравнения имеющихся материалов по данной тематике. Анализу подвергнуты личностные качества следователя, особенности образовательного процесса и влияние опыта на результаты работы, а также факторы, сопутствующие следственной деятельности (организация труда, уровень стресса, нагрузки и т. д.). Результат проведенного исследования выражен в определении проблемных факторов, влияющих на формирование криминалистического мышления следователя (дознавателя) и возможных путей их преодоления, важности такого мышления, которое остается знанием, постоянно сориентированным в сторону практики. The relevance of the article is related to the search for new ways and methods to improve the effectiveness of the fight against crime, the prompt detection of crimes, as well as the trend of «forensic thinking», which is gaining popularity among criminalists, mastering the skills of which will contribute to the most complete and objective investigation of criminal cases. Problems at present are insufficient quality of investigation and the need to improve the cognitive abilities of investigators (inquirers). The task of the study was to identify factors that influence the development and formation of forensic thinking of investigators. The purpose of the work is- to analyze the components of the process of formation of an investigator and features of his practical activities affecting the cognitive abilities in terms of forensics by studying and comparing existing materials on this topic. The analysis is subjected to the personal qualities of an investigator, the peculiarities of the educational process and the impact of experience on the results of work, as well as factors associated with the investigative activity (organization of work, stress and stress levels, etc.). The result of the study is expressed in the definition of problematic factors affecting the formation of forensic thinking of an investigator (inquirer) and possible ways to overcome them, the importance of such thinking, which remains knowledge, constantly oriented towards practice

The world is changing rapidly, so is academics. E-learning has altered the area of academics and education. ICT enabled learning has given ideal services to students by providing any type of content on demand which is proportional to the performance of students. The concentration of learner has been found instinctive; thus there is a need of engaging mind towards course progress with its entirety till the objectives of the course will be achieved. There are several e-learning platforms available as EdX, Udacity, Khan Academy, Alison those have a number of learners registered for various courses. Studies suggest that these platforms suffer from the common problem of learners’ dropping out. Investigations also claim early leaving rate is increasing due to lack of quality of content, distraction factors, learners’ mind change, outdated and succinct information, and some more detraction factors. These issues have been observed on the basis of early leaving rates in various MOOCs. Thus there is a mammoth scope for minimizing the impact of these reasons on the learners’ mind. It can be achieved by identifying these factors affecting learners’ motivation during the course. This study is aiming on identifying these factors. The approach is to explore some certain keywords on previous literature (total 41) and then calculating their frequencies and co-factors associated with them. Both grouped factors contribution and individual factor contribution have been taken care. The study gives a direction for future work towards overcoming these actor and engaging learners in ICT enabled learning.

Market reaction to surprises in earnings announcements has long been used to measure the quality of the information content of the announcement, and studies have explored various factors affecting the response. This study adds to this body of research by factoring in the level of corporate social responsibility (CSR) exhibited by the firm and employs a relatively new measure of a company’s level of CSR, rankings published by JUST Capital. I hypothesize that financial information reported by higher ranked companies is weighed more heavily by investors than those reported by non-ranked or lower-ranked companies. Using earnings response coefficients as a measure of the perceived quality of the financial information reported by the firms, my results provide direct support of the hypothesis, indicating that the market reacts more strongly to earnings surprises for firms with high JUST rankings than for unranked firms or firms with lower rankings. This result contributes new insights into the impact of a firm’s CSR in terms of the perceived quality of a firm’s financial reporting.

Progress in the field of neurosurgery and the possibility of total removal of the majority of intramedullary tumors leads to the question about maximum security functions of the spinal cord. The invention and implementation of intra-operative neuro-physiological monitoring (IOM) provides real-time to assess the impact of surgical procedures on the pathways of the spinal cord. Effective and informed monitoring includes an assessment of motor and sensitive ways to complete information about the functions of the spinal cord. Identifying predictors of favorable functional outcome and algorithm development monitoring allows the authors to modify neurosurgical tactics and improve the patient´s quality of life after surgery. This article describes all the methods IOM and physiological factors affecting the monitoring of responses. The authors review data on the effects of different anesthetics on the ability of neurons to conduct impulses and the most favorable combinations of drugs. It is proved that the IOM is effective as predictors of high risk of postoperative complications (4 studies class I and 7 studies of class II). It is important to consider the factors such as experience neurophysiologist and his ability to interpret data, as well as experience of the surgeon in using these data, the actions of the anesthesiologist - the whole process of interaction affects the final outcome of the operation.

Three groups of once-calved (OCH) heifers were slaughtered following the weaning of their calves at 3 (OCH3, n = 32), 5 (OCH5, n = 33) and 7 (OCH7, n = 31) months postcalving. A fourth group of heifers was fed a silage/grain diet and slaughtered at 15 mo of age (C, n = 32). Alternate sides of each carcass were electrically stimulated (ES) at 475 volts for 1 min (20 pulses m−1, 60 Hz) at 45 min post-stunning. All left sides were dissected into fat, lean and bone and meat quality parameters recorded. Rib eye steaks were evaluated for palatability by a trained panel and for consumer acceptability after an aging period of 6 d. All OCH groups produced heavier carcasses with a higher level of marbling than the C group after adjustment of the data to a constant proportion of carcass fatness, but the proportional yields of lean and bone tissue were similar for all heifer groups. OCH groups produced meat that was darker with a lower drip loss and higher 45 min and 6 d pH than the C group. Consumer acceptability of rib eye steaks was similar for all heifer groups, but the OCH7 (oldest) group had a higher amount of connective tissue when evaluated by a trained panel than other heifer groups. Taste panel evaluations showed that ES increased meat tenderness and overall palatability and reduced the amount of connective tissue when compared to meat from unstimulated carcasses. ES also increased the consumer acceptability of tenderness by 14.3%, flavor by 5.6%, juiciness by 5.2% and overall palatability by 6.7% over meat from unstimulated carcasses. It was concluded that once-calved heifers could produce heavier carcasses of similar composition and meat with similar eating quality to conventionally managed nonpregnant feedlot heifers. Electrical stimulation improved the consumer acceptability of meat primarily through an improvement in meat tenderness. Key words: Beef, carcass, electrical stimulation, meat quality, once-calved heifers

Researchers use various skills in their works, such as writing, data analysis and experiments design. These research skills have greatly influenced the quality of their research outputs, as well as their scientific impact. Although many indicators have been proposed to quantify the impact of researchers, studies of evaluating their scientific research skills are very rare. In this paper, we analyze the factors affecting researchers’ skill ranking and propose a new model based on hypergraph theory to evaluate the scientific research skills. To validate our skill ranking model, we perform experiments on the PLOS ONE dataset and compare the rank of researchers’ skills with their papers’ citation counts and h-index. Finally, we analyze the patterns about how researchers’ skill ranking increased over time. Our studies also show the change patterns of researchers between different skills.
