Robotic hand with remote control

В данной статье описывается процесс создания рабочей модели роботизированной руки сдистанционным управлением. Подобные устройства применяются во многих сферах деятельности человека, таких как автоматизированное производство, медицина, индустрия развлечений и, конечно, космонавтика. В этой статье, во-первых, подробно разъясняется процесс подбора компонентов, плюсы и минусы каждого из вариантов, во-вторых, поэтапно проиллюстрирован процесс сборки первого прототипа устройства, и в-третьих, изложен принцип работы устройства. В процессе разработки роборуки было выяснено, что управляющие алгоритмы для микроконтроллера не сложно написать самому. Однако организовать правильную работу датчиков оказалось весьма сложно. Автор предполагает, что это устройство будет одним из шагов к созданию высокоточных манипуляторов для использования в космосе.This article is described the process of creating of the working model of a robotic hand with remotecontrol. Similar devices are used in many fields of activity of society, such as automatic manufacture, medicine,entertainment industry and, of course, cosmonautics. This article firstly explained in detail the process of selectionof components, pluses and minuses of each of options, secondly, assembly process of the first prototype of the device is step by step illustrated, and thirdly, the working principle of the device is described. In the process of development of a robohand it has been found out that it isn't difficult to write the operating algorithms for the microcontroller. However to organize the correct operation of sensors it has appeared very difficult. The author assumes that this device will be ones more step to create high-precision manipulators for use in space

The Determinants Of Human Wellbeing In Professional Activities

The article discusses the issue of person's attitude towards success in his professional activities, which are the value of human labor and his wellbeing in professioanl activity. Personal attitude and substantial components of socio-psychological factors of attitude development provides the field of welfare of the employee. It focuses on the implementation of efficient technologies of formation attitude towards success in the process of training and retraining. The object of the research was the OJSC Evrazruda candidate pool members studying at the Evraz Siberia Regional Staff Training Center, as well as a group of experts (engineer, metallurgists). The techniques of V. K. Gerbachevsky, V. V. Stolin, S. R. Panteleyev, H. J. Eysenck, M. Rokeach, N. M. Peysakhov and J. Rotter were used in the research. The study showed the interconnection of a person's attitude with the dominant features of the component structure of motivational, volitional and self-consciousness factors. They are the determinants of wellbeing and quality of life in professional activity

Surfactant therapy restores gas exchange in lung injury due to paraquat intoxication in rats

Paraquat is a weed killer which causes often fatal lung damage in humans and other animals. There is evidence that the pulmonary surfactant system is involved in the pathophysiology of respiratory failure after paraquat intoxication and, therefore, the possible therapeutic effect of intratracheal surfactant administration on gas exchange in rats with progressive lung injury induced by paraquat poisoning was studied. In one g
