Cultural Memory as a Basis of the Social Wellbeing

In the article the author considers cultural memory as a basis of the social wellbeing. Two concepts "cultural memory" and "social wellbeing", features of their interrelation, and also influence of the person on the cultural memory formation are investigated. Modern conditions offer modern solutions. We should remember on the one hand to be proud and to have wish for further development, on the other hand to draw some conclusions also for further development. In this case we could actively use the Internet possibilities and other modern technologies. By means of modern technology we have a big range of opportunities to help people not only in the financial sphere but also in the cultural one. It can give the chance to people not to feel alone in this world. So it means they can feel comfortable within their country, within the instability world. It is the aim of the most wellbeing programs

Analysis of linear continuous crystallizer operating modes

The object of research is linear continuous crystallizer (LCC) operating modes. LCC is device, which can provide effective crystallization refining of uranyl nitrate (UN) from nitric acid solution during spent nuclear fuel (SNF) reprocessing. The purpose of the work is mathematical description of operating mode parameters - LCC operational efficiency and time required for accumulation tank filling with uranyl nitrate hexahydrate (UNH) crystals. Presented estimates have been compared with experimental data and numerical simulation results

A study of the ultrasonic treatment effect on microstructure and mechanical properties of commercial purity titanium

This work presents a study of the ultrasonic treatment effect on microstructure and mechanical properties of ac-received and recrystallized commercial purity titanium specimens by means XRD, EBSD and TEM. It was demonstrated that the dislocation density growth and the twins with special boundaries [sigma]7b and [sigma]11b increase within the surface grains during ultrasonic treatment depend on initial structural state of the titanium specimens. The relationship between the structural parametrs change and the surface layer microhardness value of the titanium specimens subjected to ultrasonic treatment was shown. It was found that differences in the hardened surface layer depth and the surface microhardness of ac-received and recrystallized titanium specimens result in the same yield and ultimate tensile strength increment during ultrasonic treatment

Обеспечение точности гироскопических систем. Современные методы и подходы

В современном мире все больше требует вмешательство в производство точное приборостроение.Точное приборостроение одно из важнейших составляющих научно-технического прогресса. Приборы,входящие в состав различных систем и комплексов по управлению движением, приборы навигации иориентации, приборы морской навигации, космические, авиационные приборы и так далее. При этомкачество выполнения таких приборов, которые изготавливаются из современных материалов и сочетаютв себе элементы точной механики, оптики, высоковольтной электроники, и определяютинструментальную точность, надежность и ресурс работы комплексов. Гироскопические приборы яркиепредставители изделий точного приборостроения и используются как в системах навигации, так и вбесплатформенных системах ориентации и стабилизации космических аппаратов. Точность инадежность современных гироскопических систем во многом зависят от стабильности формы,геометрических размеров, прочности материалов и способов получения материалов деталей, входящих всостав конструкции высокоточных узлов. В данной работе будут рассмотрены методы и способыобеспечения точности гироскопических систем в зависимости от использованного материала в деталях, аименно, для сплава 40ХНЮ-ВИ.In the modern world the interference in production exact instrument making requires more and more.Precision instrument making one of the most important components of scientific and technical progress. Theinstruments which are a part of different systems and complexes on traffic control, instruments of navigation andorientation, instruments of sea navigation, space, aviation instruments and so on. At the same time quality ofexecution of such instruments which are manufactured of the modern materials and is combined by elements ofexact mechanics, optics, high-voltage electronics, and determine the instrumental accuracy, reliability and aresource of operation of complexes. Gyro instruments bright representatives of products of exact instrument makingare also used both in systems of navigation, and in the navigation systems without platform and stabilizing ofspacecrafts. Accuracy and reliability of the modern gyroscopic systems in many respects depend on stability of theform, the geometrical sizes, durability of materials and methods of receiving materials of the details which are apart of construction of high-precision nodes. In this operation methods and methods of support of accuracy ofgyroscopic systems depending on the used material in details namely for an alloy 40HNYU-VI will be considered
