Status of NSLS-II booster

The National Synchrotron Light Source II is a third generation light source under construction at Brookhaven National Laboratory. The project includes a highly optimized 3 GeV electron storage ring, linac pre-injector and full-energy booster-synchrotron. Budker Institute of Nuclear Physics builds booster for NSLS-II. The booster should accelerate the electron beam continuously and reliably from minimal 170 MeV injection energy to maximal energy of 3.15 GeV and average beam current of 20 mA. The booster shall be capable of multi-bunch and single bunch operation. This paper summarizes the status of NSLS-II booster.Национальный источник синхротронного излучения II является синхротроном третьего поколения, созданным в Брукхевенской национальной лаборатории. Проект включает: высокооптимизированное накопительное кольцо на 3 ГэВ, линейный ускоритель и бустерный синхротрон на полную энергию. Институт ядерной физики им. Г.И. Будкера создает бустер для NSLS-II. Бустер должен надежно и непрерывно ускорять пучок электронов от минимальной энергии инжекции 170 МэВ до максимальной энергии 3,15 ГэВ с током пучка 20 мА. Бустер должен быть способен работать в односгустковом и многосгустковом режимах.

Estimation, Interpretation and Prognostic Value of Height-and-Mass Indices in Overweight and Obese Children in Early Stages of Disease

In this paper we have analyzed such height-and-mass indexes as body mass index, fat body mass and lean body mass taking into account age of overweight and obese children; results of their study are presented, the importance of their calculation and prognostic significance has been proved

Business education: Global trends and prospects

Business education in the world is developing at a fairly high pace. The reason for this is the possibility of exchanging experience between different countries in the field of entrepreneurial technologies, as well as the need to improve the relationship between the "scientific minds" of different countries. In this regard, the leading educational institutions of the world develop and implement various training programs aimed at improving the skills of students in the field of marketing, management, the world economy, as well as international economic relations. International business education should be studied from the perspective of measuring the effect of internationalization of business schools and training programs by offering international training courses, foreign exchanges, subsidiaries, knowledge exports, various types of cooperation

The results of prospective multicenter study of the effectiveness of amino acid formula in infants with severe atopic dermatitis and allergy to cow’s milk proteins

The article presents the main results of prospective multicenter study of effectiveness of using amino acid formula in diet therapy for the infants with severe atopic dermatitis (AD) and allergy to cow's milk protein (CMP). The study was conducted in 5 centers of Ukraine and included 30 infants with severe atopic dermatitis (EASI score > 18) aged from 29 days to 11 months. 22 patients completed the study. Diet therapy considered administration of amino acid formula containing 100 % free amino acids, for 4 weeks. Evaluation of clinical effectiveness of AD and allergy to CMP diet therapy with amino acid formula was carried out on the 7th, 14th and 28th day after reaching the full daily volume of the formula. Provocative test was performed on the 28th day with extensively hydrolyzed whey protein formula followed with evaluation of immediate and late reactions. Infants with severe AD (EASI score > 18) were characterized by impairment of several organs and systems: in 68 % of cases skin symptoms were associated with the gastrointestinal signs like change in stool frequency (constipation, diarrhea), appearance of pathological admixtures in feces (mucus, blood), vomiting, and others. With administration of amino acid formula significant decrease in severity of skin (98 %) and gastro-intestinal manifestations of food allergy (82 %) were seen. Amino acid formula was well tolerated by children with severe AD and, if needed, it might be used as a therapeutic formula for an exclusive feeding of infants with severe allergies to CMP. Duration of the diet therapy should not be less than 4 weeks. High effectiveness of this formula in infants with AD was proved by parents and doctors
