Using of a new additional sonometric marker in diagnostics of infringements of formation of the hip in infants of the first year of life

Comparison of the X-Ray and Ultrasound studies was made in 136 infants (272 joints) according to the number of objective factors as a width of a ultrasound signal from bottom edge of iliac bone, a presence or an absence of a center of ossification influence on the accuracy of an ultrasound estimation of a bony acetabular rim in infants of the first year of life in diagnostics of dysplasia of the hip joint. Certain group of infants with well-defined viewing of bottom edge of iliac bone the (152 joints) was selected. Where we presented comparison results of ultrasound and X-Ray angle’s data. We used the modification scheme of a marking in infants with insufficiently accurate visualization of the bottom edge of iliac bone (102 joints), where the line of the bony rim was spent through the center of wide ultrasound signal from the bottom edge of iliac bone. We found authentic distinctions between the sizes of the X-Ray acetabular angle and the angle of the bony rim lead to X-Ray scheme in all infants and increase of these distinctions at an unclear signal from bottom edge of iliac bone. Using of our ultrasound scheme allows receiving sizes of angles that authentically not differ from X-Ray data.Исходя из того, что на точность ультрасонографической оценки угла костной крыши вертлужной впадины у детей первого года жизни при диагностике дисплазии тазобедренных суставов оказывают влияние ряд объективных факторов, таких как ширина эхо-сигнала от нижнего края подвздошной кости, наличие или отсутствие ядра окостенения, были выполнены сопоставления рентгенологических и ультрасонографических данных у 136 детей (272 сустава). Отдельно выделена группа детей с четкой визуализацией нижнего края подвздошной кости (152 сустава), где также выполнены сопоставления рентгенологических и ультрасонографических угловых характеристик. У детей с недостаточно четкой визуализацией нижнего края подвздошной кости (102 сустава) нами использовалась модифицированная схема разметки, при которой линия костной крыши проводилась через центр широкого эхосигнала от нижнего края подвздошной кости. Выявлены достоверные различия между величиной рентгенографического ацетабулярного угла и приведенного к рентгеновской схеме угла костной крыши у всех детей, а также возрастание этих различий при нечетком сигнале от нижнего края подвздошной кости. Использование предложенной нами ультрасонографической схемы позволяет получить величины угла, достоверно не отличающиеся от рентгеновских

Comparative effects of blue light and red light on the rates of oxygen metabolism and heat production in wheat seedlings stressed by heat shock

The effect of blue light (BL, bandwidth 420-460 nm) and red light (RL, bandwidth 620-640 nm) on the rates of consumption and evolution of oxygen and rate of heat production of plants after action of high temperature (45 °C during 30 min) was studied. The rate of heat production was used as indicator of plant resistance to the action of unfavourable factors, since this index reflects the physiological condition. The object of investigation were the seedlings of summer wheat. The blue light compared with red light had favourable effects on the rates of oxygen metabolism. The rate of O2 evolution of wheat seedlings with blue light was higher by 50% (optimal temperature) and by 60% (after action 45 °C temperature) as seedlings with red light. The rate of oxygen consumption of seedlings treated by high temperature with blue light was inhibited by 40-45% as control, whereas this index was decreased by 75% in plants after temperature shock with red light. Heat production rate of wheat seedlings grown in blue light was higher than the heat production rate of seedlings grown with red light. © 2002 Elsevier Science B.V. All rights reserved

Event-driven simulation of the state institution activity for the service provision based on business processes

The paper presents an approach, based on business processes, assessment and control of the state of the state institution, the social insurance Fund. The paper describes the application of business processes, such as items with clear measurable parameters that need to be determined, controlled and changed for management. The example of one of the business processes of the state institutions, which shows the ability to solve management tasks, is given. The authors of the paper demonstrate the possibility of applying the mathematical apparatus of imitative simulation for solving management tasks

ДЕЛОВАЯ АКТИВНОСТЬ КАК ОПЕРЕЖАЮЩИЙ ИНДИКАТОР ЭКОНОМИЧЕСКОГО РАЗВИТИЯ: ЗАРУБЕЖНЫЙ И РОССИЙСКИЙ ОПЫТ

Foreign experience of indication business activity began to emerge in 20-30-ies of XX. To date, overseas system business activity monitoring is conducted by government agencies, Central and investment banks, associations, business schools, research centres. Russian practice of indication of business activity is quite diverse, however, not all indexes (IDA) have a long history and are outstripping. To identify those or other IDA (formal and informal) as leading indices and the need to evaluate their correlation with indicators of development of the national stock market.Зарубежный опыт индикации деловой активности начал формироваться в 20-30-е годы ХХ в. На сегодняшний день за рубежом системный мониторинг деловой активности проводится правительственными органами, центральными и инвестиционными банками, ассоциациями, школами бизнеса, исследовательскими центрами. Российская практика в области индикации деловой активности достаточно разнообразна, однако далеко не все индексы (ИДА) имеют длительную историю и являются опережающими. Для идентификации тех или иных ИДА (официальных и неофициальных) в качестве опережающих индексов требуется оценка их корреляции с индикаторами развития национального фондового рынка

The Black Sea Region Energy Cooperation: Current Trends and Prospects

The Black Sea region is one of the most complex regions in terms of energy development. It hosts several major powers and some developing countries that need to cut energy costs. In general, the region is controversial. It is influenced by external actors, and therefore regional stability is very difficult to achieve. In addition, institutional players such as the EU, the Belt and Road Initiative, the Black Sea Trade and Development Bank, etc., have their own vision of the future of the Black Sea region. The article is aimed at assessing the regional balance of power and estimating the interests of the countries of the region. Based on this assessment, the authors have classified the countries in the region, predicted potential alliances, and provided recommendations on how the countries should behave in the region. The key findings comprise the rejection of the two hypotheses: the countries of the region cooperate mainly through similar institutions; and the countries of the region can efficiently cooperate within the framework of a single strategy. The novelty of the article is in a new look on the regional distribution of power and new strategies for cooperation between countries in the region.Keywords: The Black Sea region, energy sector, strategy, institutions, balance of powerJEL Classifications: F59, Q48DOI: https://doi.org/10.32479/ijeep.11247</p

Comparison of hematological indicators after implantation with ceramic osteoplastic materials.

In this work, a comparative study of the dynamics (4 and 10 weeks after surgery) of hematological parameters during the implantation of ceramic osteoplastic materials was carried out: beta tricalcium phosphate and lanthanum zirconate on a model of a femur diaphysis fracture in guinea pigs. According to the study, it was concluded that lanthanum zirconate can be used as an osteotropic material.В представленной работе проведено сравнительное изучение динамики (4 и 10 недель после операции) гематологических показателей при имплантации керамических остеопластических материалов: бета-трикальций фосфата и цирконата лантана на модели перелома диафиза бедренной кости у морских свинок. По результатам исследования был сделан вывод о возможности применения цирконата лантана как остеотропного материала

Pathogen Entrapment by Transglutaminase—A Conserved Early Innate Immune Mechanism

Clotting systems are required in almost all animals to prevent loss of body fluids after injury. Here, we show that despite the risks associated with its systemic activation, clotting is a hitherto little appreciated branch of the immune system. We compared clotting of human blood and insect hemolymph to study the best-conserved component of clotting systems, namely the Drosophila enzyme transglutaminase and its vertebrate homologue Factor XIIIa. Using labelled artificial substrates we observe that transglutaminase activity from both Drosophila hemolymph and human blood accumulates on microbial surfaces, leading to their sequestration into the clot. Using both a human and a natural insect pathogen we provide functional proof for an immune function for transglutaminase (TG). Drosophila larvae with reduced TG levels show increased mortality after septic injury. The same larvae are also more susceptible to a natural infection involving entomopathogenic nematodes and their symbiotic bacteria while neither phagocytosis, phenoloxidase or—as previously shown—the Toll or imd pathway contribute to immunity. These results firmly establish the hemolymph/blood clot as an important effector of early innate immunity, which helps to prevent septic infections. These findings will help to guide further strategies to reduce the damaging effects of clotting and enhance its beneficial contribution to immune reactions

Studies of new Higgs boson interactions through nonresonant HH production in the b¯bγγ fnal state in pp collisions at √s = 13 TeV with the ATLAS detector

A search for nonresonant Higgs boson pair production in the b ¯bγγ fnal state is performed using 140 fb−1 of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. This analysis supersedes and expands upon the previous nonresonant ATLAS results in this fnal state based on the same data sample. The analysis strategy is optimised to probe anomalous values not only of the Higgs (H) boson self-coupling modifer κλ but also of the quartic HHV V (V = W, Z) coupling modifer κ2V . No signifcant excess above the expected background from Standard Model processes is observed. An observed upper limit µHH &lt; 4.0 is set at 95% confdence level on the Higgs boson pair production cross-section normalised to its Standard Model prediction. The 95% confdence intervals for the coupling modifers are −1.4 &lt; κλ &lt; 6.9 and −0.5 &lt; κ2V &lt; 2.7, assuming all other Higgs boson couplings except the one under study are fxed to the Standard Model predictions. The results are interpreted in the Standard Model efective feld theory and Higgs efective feld theory frameworks in terms of constraints on the couplings of anomalous Higgs boson (self-)interactions
