Синтез молекулярных фотопреобразующих систем на основе тетра-фенилпорфирина и пурпурина 18

Donor-acceptor systems based on 5-(p-aminophenyl)-10,15,20-triphenylporphyrin, purpurin 18 and 2-(2-hydroxyethyl)thio-3-methyl-1,4-naphthoquinone were synthesized to simulate the natural photoconverting systems. Their spectral properties were studied.Получены донорно-акцепторные системы на основе 5-(п-аминофенил)-10,15,20-трифенил-порфирина, пурпурина 18 и 2-(2-гидроксиэтил)тио-3-метил-1,4-нафтохинона для моделирования природных фотопреобразующих комплексов и изучены их спектральные свойства

Keeping up with revolutions: evolution of higher education in Uzbekistan

Uzbekistan's higher education system has undergone some dramatic changes in the past century, evolving from largely traditional religious colleges to fully state-funded communist-atheist institutions. Since the end of the communist administration and subsequent market-oriented reforms, the institutions of higher education (IHE) in Uzbekistan have had to reinvent and reform themselves again, as the demand for different kind of education increased. This paper puts the current changes and trends in IHEs into an historical perspective and highlights some important effects of the market reforms on the educational scene

Law, Social Norms and Welfare as Means of Public Administration: Case Study of Mahalla Institutions in Uzbekistan

Despite numerous challenges, since its independence, Uzbekistan, with the exception of the May 2005 Andijan events, has enjoyed extraordinary political stability and not recorded any considerable cases of interethnic or interfaith conflict, regime change or civil war, whereas neighboring Kyrgyzstan, labeled an “island of democracy” by the Western world, has experienced numerous conflicts and chaos, ranging from “color revolutions” to ethnic conflict. However, for understanding Uzbekistan’s ability to cope with internal and external challenges, little recourse is made to the post-independence discourse on public administration known as “mahalla reforms”. In spite of the significant existing body of literature on the mahalla, there has been little systematic scholarly investigation of the role of mahalla in maintaining political stability and security in Uzbekistan. Previous studies did not provide an account of how the law, social norms and welfare come to interplay in the mahalla system and how this influences the public administration developments in Uzbekistan. This paper begins to redress this lacuna by analyzing public-administration reforms in post-independence Uzbekistan, namely mahalla reforms, with an effort to show how political and social stability is established through mahalla, and to what extent those reforms have affected the position of individuals vis-à-vis the public-administration system. In undertaking this task, the paper employs three theoretical concepts: the theory of norms, the welfare-pentagon model and the theory of social control. In this paper, I argue that public-administration reforms since 1991 have transformed mahalla into a comprehensive system of social control; and therefore, mahalla can be places of democratic involvement or sites of authoritarianism in Uzbekistan

Synthesis of molecular photoconverting systems based on tetraphenylporphyrin and purpurin 18

Donor-acceptor systems based on 5-(p-aminophenyl)-10,15,20-triphenylporphyrin, purpurin 18 and 2-(2-hydroxyethyl)thio-3-methyl-1,4-naphthoquinone were synthesized to simulate the natural photoconverting systems. Their spectral properties were studied

Clinical and Endoscopic Diagnostics of Foreign Bodies of the Respiratory Tract in Children

For the period from January 2000 to June 2019, 1355 children with suspected foreign bodies of the respiratory tract were inpatient treatment and examination in the department of thoracic surgery of the 2 SamMI clinic. The main group of children consisted of children of the first 7 years of life (88.6%), of which the most numerous was the group of children of early age (56.3%). Of the 1355 children hospitalized with suspected foreign bodies of the respiratory tract, 407 (30.0%) had the diagnosis excluded, and 948 (70.0%) had the diagnosis confirmed. Among the examined patients, 858 boys (63.3%) prevailed, compared with 497 girls (36.7%). Children from rural areas prevailed 4.5 times over urban areas, 1107 (81.7%) versus 248 (18.3). 1162 (85.8%) children were admitted in a moderately serious condition. A serious condition was noted in 167 (12.3%) patients. An extremely serious condition when seeking help was observed in 24 (1.8%) children. In addition, children who aspirated organic foreign bodies into the respiratory tract 759 (80.1%) significantly prevailed, compared with children who aspirated inorganic foreign bodies 172 (18.1%). 17 (1.8%) have self-withdrawal
