Comparative analysis of habitus and behavioral responses in birds in desynchronosis conditions

The dynamics of behavioral reactions is studied. Habit, live weight of roosters in artificially created models of desynchronosis: acute, due to three-day inversion of the light regime, and chronic, due to crowding - increased placing density. An assessment of the behavior, habitus, feed intake, feather cover and molting conditions in combination with the glycemia level, which together provide an objective assessment of the effect of desynchronosis on the functional state of birds and their adaptation to acute and chronic stres

Using video in the process of teaching a foreign language at a university

The purpose of the article is to analyze the literature on the feasibility of using video clips at foreign language classes, as well as to demonstrate the capabilities of video, which allow you to use it as the most effective tool in the context of a modern approach to teaching foreign languages at a Universit

Hemodynamic criteria of the circulatory system in ethnic groups of students with different types of autonomic regulation of the heart rate

Under physiological conditions, the first years of university studies of the students of Arabic and African subgroups with MPAR and PPAR HR were characterized by toughness, low effectiveness of the system of blood circulation, increased peripheral vascular resistance, vascular TSC; Indian and Latino-American subgroups with MPAR HR revealed the weakness and low efficiency of the circulatory system, the optimal GPBC and cardiovascular TSC were revealed in Indian and Latino-American subgroups with MPAR HR, and subgroups with PPAR HR showed high endurance of the circulatory syste

Health ecology: factors of spread and consequences of viral hepatitis manifestation

The features of viral hepatitis B (HB) and C (HC) in the initial making of these diagnoses in three age groups of men and women (25-30, 31-55 years old for women and 31-60 years old for men, over 55 for women and 60 years old for men) were studied. High levels of bilirubin in the blood serum in all groups indicated damage of the functions of hepatocytes, especially in men with hepatitis B, in women with hepatitis C. The high ALT activity indicated an increase in cytolytic processes in liver hepatocytes in all groups with viral HB and HC, especially in men of the younger group, in women of the younger and middle-aged grou

Features of physical development of schoolchildren in the conditions of specialized training

The article presents a comparative analysis of physical development of 13-year-olds and cadet basic profile of teaching in urban schools in the parameters of somatometry and visiometry characterizing physical development, functional state, adaptation of the heart and body to current training loads. Coming of puberty is marked by intense growth of the body with heterochronous changes in the proportions and dimensions of its muscular skeletal system and the structure of internal organs. During this period, the role of mechanisms for self-regulation of heart activity and, in general, autonomous regulation of the functions of the cardiovascular system increase
