Некоторые аспекты нормирования загрязняющих веществ в почве

There are considered Russian and foreign valuation experience of pollutants in soils. Actuality of the topic is that the soil plays an important role in the natural habitat of human. First of all, the soil is the main means of agricultural production, referring to the category of non-renewable natural resources.Рассмотрен российский и зарубежный опыт нормирования загрязняющих веществ в почвах. Актуальность данной темы заключается в том, что почве принадлежит важная роль в природной среде обитания человека прежде всего потому, что почва - основное средство сельскохозяйственного производства, относящееся к категории возобновимых природных ресурсов

Age at first birth in women is genetically associated with increased risk of schizophrenia

Prof. Paunio on PGC:n jäsenPrevious studies have shown an increased risk for mental health problems in children born to both younger and older parents compared to children of average-aged parents. We previously used a novel design to reveal a latent mechanism of genetic association between schizophrenia and age at first birth in women (AFB). Here, we use independent data from the UK Biobank (N = 38,892) to replicate the finding of an association between predicted genetic risk of schizophrenia and AFB in women, and to estimate the genetic correlation between schizophrenia and AFB in women stratified into younger and older groups. We find evidence for an association between predicted genetic risk of schizophrenia and AFB in women (P-value = 1.12E-05), and we show genetic heterogeneity between younger and older AFB groups (P-value = 3.45E-03). The genetic correlation between schizophrenia and AFB in the younger AFB group is -0.16 (SE = 0.04) while that between schizophrenia and AFB in the older AFB group is 0.14 (SE = 0.08). Our results suggest that early, and perhaps also late, age at first birth in women is associated with increased genetic risk for schizophrenia in the UK Biobank sample. These findings contribute new insights into factors contributing to the complex bio-social risk architecture underpinning the association between parental age and offspring mental health.Peer reviewe

Approximate method of solving resource allocation problem based on solutions of minimal coverage in the system of parallel data processing

Запропоновано наближений метод виключень на основі рішення задачі про найменше покриття для систем паралельної обробки даних. Удосконалено метод планування завдань на основі наближеного рішення задачі про найменше покриття, що дозволяє за рахунок малої часової складності підвищити оперативність планування в 1,3 – 2,7 разів.Предложен приближенный метод исключений на основе решения задачи о наименьшем покрытии. Метод исключений работает на порядок быстрее, чем известные лучшие методы, что позволяет применять его, как инструмент планирования распределением ресурсов в системах, где процесс планирования осуществляется в режиме реального времени при размерности задачи (N 0,9. Экспериментально доказано, что погрешность предложенного алгоритма не превышает 4-5% и уменьшается с увеличением размерности решаемой задачи.An approximate method of exceptions on the basis of solving the problem of minimum coverage. Method exceptions works much faster than the known best practices, it can be used as a planning tool for resource allocation in systems where the planning is done in real time with the problem dimension (N 0.9. Experimentally proved that the error of the algorithm does not exceed 4-5% and decreases with increasing dimension of the problem being solved

Possibilities of using integrated learning in teaching English in a non-linguistic college

In the current conditions, apart from high-quality professional education, a crucial component of a specialist's competitiveness is the knowledge of a foreign language (further on - FL). Because of this, during the training of higher educational institutions' students, learning a FL requires considering professional specifics and its orientation on actualizing the professional activity tasks. Hence, methods of teaching a FL as a science are faced with the aim of searching for the optimal ways of reaching a sufficient level of FL knowledge for professional goals. Therefore, the aim of present article is to discuss the specifics of various methods of teaching a FL for professional communication and the possibilities of using them in a nonlinguistic college. In the context of present study, integrated learning is defined as learning, in which the focus is shifted from isolated teaching of a FL for professional communication to integration of learning the language with studying special disciplines. Analysis of theoretical developments and conduction of an experimental study showed that teaching a FL for professional communication on the basis of the CLIL methodology is efficient for students of a non-linguistic college. © 2017
