Abstract: In estimating the safety of underground pipeline operated in complicated engineering and geological conditions, it is necessary to know and consider the main regularities caused by pipeline interaction with soil. Presented in this article mathematical model of pipeline spatial bend under the action of group of loadings and influences allows estimate influence of complicated geological conditions and design features on pipeline’s stressed-deformed state and reliability.Keywords: acceptable risk, admissible risk… Show more

The book covers the basic principles of nutrient rationing for poultry. The data on the needs of all types of poultry, taking into account age, in nutrients, minerals and biologically active substances are given. The characteristic of the main feed means and rational norms of their inclusion in the compound feed for poultry are given. Modern data on the role of vitamins, macro- and microelements, enzyme preparations, probiotics, prebiotics, phytobiotics, organic acids, antioxidants, fat emulsifiers and other sources of biologically active substances in poultry nutrition are presented. Attention is paid to the main technological parameters of poultry keeping. The nutritional factors that reduce immunity, as well as the causes of the main diseases associated with the quality of feed, with violations in the rationing of nutrient, mineral and biologically active substances, the technology of feeding and keeping poultry, are described, methods of their prevention are given. Criteria for the adequacy of nutrition and maintenance of a bird to its genetic potential are stated. The book is intended for specialists and managers of poultry farms, enterprises of the feed industry, researchers, graduate students and students.
