The Synthesis of Styrene-Oligoester Copolymer and Investigation of Their Physico-mechanical Properties

The copolymerization reaction of commercial propylene oxide with glycidylmethacrilate in the presence of BF3·O(C2H5)2 catalyst have been investigated. The composition and structure of copolymerization products and anchored functional groups have been determined using IR and gel chromatographic methods. The physico-mechanical properties and utility of polyfunctional unsaturated oligoester were investigated. The obtained thermoset product via the reaction of the oligoester with both styrene and oligostyrene obtained from the bottom of column as a waste material during the rectification operation of styrene in the presence of radicalic initiator has a good adhesion capability, hardness and high heat and water resistance. Thus the waste material was converted to the high valuable polymeric material

The results of the study of pain in women with external genital Endometriosis

90 women of reproductive age, including 70 women with pain syndrome of varying severity in external genital endometriosis, were examined to identify the features of pain symptoms. Studied socio-demographic indicators, developed a questionnaire of pain, depending on the nature of pain and the severity of associated symptoms. The results of the study revealed that the intensity of the pain syndrome had no correlation with the localization of the process, the presence or absence of infiltrative growth of endometriosis, the number of endometrioid lesions, and the intensity of the pain syndrome is not related to the duration of the pain. But the duration of the pain syndrome is associated with the degree of prevalence of medium-strength external genital endometriosis correlation significant relationship (r=0.33; p<0.001). Conclusion: Pain syndrome in external genital ndometriosis is associated not only with the pathological process itself, but also with morphological changes in structures, the degree of prevalence of the focal process, forming directly the substrate of pain.Обследовано 90 женщин репродуктивного возраста, из которых 70 женщин с болевым синдромом различной степени тяжести на фоне наружного генитального эндометриоза, с целью выявления особенности болевой симптоматики. Изучены социально-демографические показатели, разработана анкета болевых ощущений в зависимости от характера боли и выраженности сопутствующих симптомов. По результатам исследования выявлено, что интенсивность болевого синдрома не имела корреляционную связь с локализацией процесса, наличия или отсутствия инфильтративного роста эндометриоза, от количества эндометриоидных очагов поражения, а также интенсивность болевого синдрома не связана с длительностью боли. Но длительность болевого синдрома связана со степенью распространенности наружного генитального эндометриоза средней силы корреляционной достоверной связью (r=0,33; p<0,001). Вывод: Болевой синдром при наружном генитальном эндометриозе связан не только с самим патологическим процессом, но и с морфологическими изменениями структур, степенью распространенности очагового процесса, формируя непосредственно субстрат боли

DYNAMICS OF FORMATION CONDITIONS OF PRIMARY ELEMENTS IN THE NORTHERN AND MIDDLE PARTS OF THE СASPIAN SEA

An attempt to analyze the degree of the Volga flow influence on the conditions of biogenic elements in the Northern and Middle parts of the sea has been made. The goal is to reveal the formation mechanism of the biogenic substances conditions and the reasons of long-term changes of hydrochemical conditions of waters on the northwest shelf on the basis of available literary and fund data. For this purpose the whole period of observations has been divided into the intervals with various water levels in the Volga and in the sea

Psycholinguistic Features Not Literary Words

In the National Language Science today, the development of social language dialects is of particular interest. This article studies linguistic, psycholinguistic features of zhargon, argo and slag. Scientific ideas and views of some author's research in this area are analyzed. To date, the study of the characteristics of the language and speech, which is a means of communication, is important, the question of the scientific study of the national language is also relevant. The article we are talking about the need to study jargon words as a special layer of non-strained language. It addresses the psycholinguistic features of words-jargon, Argo and slang from a scientific point of view. Such words change and develop with the emergence of new words and concepts associated with the development of society. This article discusses the jargon used in Uzbek in everyday communication. It contains young generation slang words, which are the main layers of society

STUDYING CHEMICAL INTERACTION IN THE Ga-SrGaSe2 SYSTEM

&lt;p&gt;The chemical interaction in the Ga-SrGaSe2 system was studied using complex methods of physicochemical analysis: differential thermal analysis (DTA), X-ray diffraction analysis (XRD), microstructural analysis (MSA), as well as determination of density and microhardness; a T-x phase diagram was constructed. The phase diagram of the system was partially quasi-binary and was accompanied by eutectic equilibrium and peritectic transformation. A degenerate eutectic is formed on the Ga side of the system. In the Ga-SrGaSe2 system, no dissolution was detected on both sides.&lt;/p&gt
