The article discusses the destructive influence of totalitarian sects and offered directions of interaction between public authorities and society in the protection of the constitutional rights of minors.

In this article features and problems of professional formation of the identity of the teacher who is characterized by existence of helplessness as the characteristic influencing all spheres of the life and activity of the person interfering growth of the personality and evolutionary processes in society are considered. The author raises the questions of formation of the theory of personal helplessness and also the reason of formation of helplessness of teachers and ways of her overcoming.

Humanity does not stay static, but develop successfully in every sphere of life. We are also keeping up with the scientific progress, however, innovations have entailed ecological catastrophes. Rapid increase in population, intensifications of waste products lead to changes in nature and reflect on the life of every leaving creature. In this article I have examined the formation of ozone holes as an ecological problem and reasons for destruction of the ozone layer. I have payed particular attention to getting to know the consequences of this demolition and ways of preventing and saving it. The author has provided the material about how does the ozone layer influence one’s life and health.

In this article substantiates the relevance of research into the material of the rim of a locomotive wheel, in particular, the assessment of its cold resistance by the method of determining impact strength. A calculated FE calculation of the sharpness-deformed state of the sample during impact bending testing is carried out, taking into account the sample of plastic hardening of the material. The results of the calculation show that the accumulation and deformation of along the sample notch is contribute a localization of deformation and determinate a more rigid stress-strain state of the pre-damaged material. Thus, the impact strength of a sample made of a material of construction with a long service life decreases due to a more rigid stress-strain state, which contributes to the onset of a ductile-brittle transition at a higher temperature. A method is proposed for assessing the cold resistance of using a numerical FEM calculation of a sample for impact strength, taking into account the actualized movement of the contact samples and the stand. The causes of typical errors in solving such problems are explained.
