The migrants' remittances tendency

This article provides information on the grouping of countries in the world by economic indicators, the trend of migrant workers, major countries that send remittances and developing countries that receive remittances, as well as the share of remittances in counties’ GDP. The article also provides a comprehensive overview of the impact of migrants’ remittances on the economies of recipient countries as a result of global economic changes. The information in the article is presented in tabular and graphical form

Advanced composite alloys for constructional parts of robots

In recent years all over the world special attention has been paid to the development and implementation of nanostructured materials possessing unique properties and opening fascinating prospects for the development of technical progress in various fields of human activities. A special place can be given to the development of service robots, the market of which is actively developing. There is problem associated mainly with the lack of heatstrengthened alloys which consists in low thermal stability of the alloy properties under the conditions of elevated variable temperatures and loads. The article presents studies to assess the effect of composition, the amounts of refractory nanoscale particles and methods for their introduction into the melt on the structure and properties in nanostructured composite aluminum alloys. The powders of metals, alloys, as well as silicon carbide and aluminum oxide were used to produce the nanostructured powder composite materials. As a result of the research, NPCM compositions containing micro-size particles of transition metals that are carriers of nanosized reinforcing particles and initiators of the formation of an intermetallide of endogenous origin in a melt

On the efficiency of personnel management in modern organization

Целью изучения эффективности системы управления персоналом является практическое применение: эффективность должна быть измеримой, верифицируемой. Именно поэтому авторы работы приводят экономические расчеты эффективности организации системы работы персонала в организации. Гипотеза заключается в том, что применение данной технологии может быть осуществлено в организациях, стремящихся измерить эффективность работы персонала. Методы исследования традиционные: математическая статистика, анализ и синтез, метод логический, метод обобщения. Результатом работы является то, что просчитана эффективность системы управления персоналом с точки зрения следующих компонентов: экономическая, социальная и организационная эффективность.The purpose of studying the effectiveness of human resource management system is a practical application: performance must be measurable, ver-fitsiruemoy. That is why the authors of the calculations result in economic efficiency of the organization of the system of personnel in the organization. The hypothesis is that the use of this technology can be implemented in organizations seeking to measure the efficiency of the staff. Traditional Research Methods: mathematical statistics, analysis and synthesis, logical method, synthesis method. The work is what is counted effectiveness of the personnel management system in terms of the following components: economic, social, and organizational effectiveness

Oxytocin regulates body composition

The primitive neurohypophyseal nonapeptide oxytocin (OXT) has established functions in parturition, lactation, appetite, and social behavior. We have shown that OXT has direct actions on the mammalian skeleton, stimulating bone formation by osteoblasts and modulating the genesis and function of bone-resorbing osteoclasts. We deleted OXT receptors (OXTRs) selectively in osteoblasts and osteoclasts using Col2.3Cre and Acp5Cremice, respectively. Both male and female Col2.3Cre+:Oxtrfl/fl mice recapitulate the low-bone mass phenotype of Oxtr+/- mice, suggesting that OXT has a prominent osteoblastic action in vivo. Furthermore, abolishment of the anabolic effect of estrogen in Col2.3Cre+:Oxtrfl/fl mice suggests that osteoblastic OXTRs are necessary for estrogen action. In addition, the high bone mass in Acp5Cre+:Oxtrfl/fl mice indicates a prominent action of OXT in stimulating osteoclastogenesis. In contrast, we found that in pregnant and lactating Col2.3Cre+:Oxtrfl/fl mice, elevated OXT inhibits bone resorption and rescues the bone loss otherwise noted during pregnancy and lactation. However, OXT does not contribute to ovariectomy-induced bone loss. Finally, we show that OXT acts directly on OXTRs on adipocytes to suppress the whiteto- beige transition gene program. Despite this direct antibeiging action, injected OXT reduces total body fat, likely through an action on OXT-ergic neurons. Consistent with an antiobesity action of OXT, Oxt-/- and Oxtr-/- mice display increased total body fat. Overall, the actions of OXT on bone mass and body composition provide the framework for future therapies for osteoporosis and obesity

Rivet, RivetHZTool and HERA - A validation effort for coding HERA measurements for Rivet

During the DESY summer student program 2021, young scientists from more than 13 different countries worked together, connecting from remote, to provide computer codes within the Rivet framework for 18 HERA measurements. Most of these measurements were originally available within the HZTool package, but no longer accessible for mod- ern analysis packages such as Rivet. The temporary RivetHZTool interface was used to validate most of the new Rivet plugins
