Sufficient integral criteria for instability of the free charged surface of an ideal liquid

Applying the method of integral estimates to the analysis of three-wave processes we derive the sufficient criteria for the hard loss of stability of the charged plane surface of liquids with different physical properties. The influence of higher-order wave interactions on the instability dynamics is also discussed.Comment: 9 page

Hormonal panel of various breeds of cattle under the conditions of temperature stress

The article gives the data on the content of a number of steroid and thyroid hormones in the population of Tagil, Suksun and Holstein cattle under the conditions of increasing environmental temperature resulting in moderate stress reaction, as well as on the changes in endocrine system after temperature stress. Changes in function of vascular glands were found showing high resistance of Tagil cattle, moderate resistance of Suksun cattle and low resistance of Holstein cattle to temperature stress. The most significant changes were noted in thyroid panel of Tagil cattle that was shown by increasing synthesis of iodothyronine while environmental temperature changed from high to normal values (during post-stress period). The breeds with lower resistance had the signs of deterioration of adaption mechanism expressed in stronger unbalance reaction of hormonal axis

Clinical and psychological features of addict people with an incomplete suicide attempt

The article presents results of social, psychological and clinical aspects of suicidal behaviour of alcohol addicts and drug addicts with incomplete suicide attempts, admitted to the Department of crisis states and psychosomatic disorders, Sklifosovsky Research Institute of Ambulance Service from November 2014 to June 2015. The majority of addicts (70%) showed an affective kind of suicidal actions. During an acute post-suicidal period all examined patients revealed value-oriented approach to life. Conflict becomes irrelevant as a result of expressed fear of death and fear of social and transcendental consequences of an suicide act. Alcohol addicts feel guilty towards relatives and others, and need of their support. They have significantly increased fear to loss of social identity. Drug addicts have maintained negative view of near and distant future events, they consider the act of suicide as an effective and radical way of solving life problems. Based on our findings we concluded that the risk of repeat suicide attempts in patients with alcohol dependence can be caused by the weakness of self-management skills and lack of microsocial environmental support, while a similar risk in persons with drug addiction can be due to negative view of their own future and the degree of social maladjustment
