Етнополітична система постає і структурується під час взаємодії етнічності з політикою. Беручи участь у політиці, етнічні спільноти конкурують між собою за встановлення певних преференцій, цим самим вносячи дестабілізацію в етнополітичну систему
New Information about the Mingtepa City Monument
This article provides new information about the city monument of Mingtepa, located in the northern part of the Sоgd region. The first information about the city monument of Mingtepa was recorded in the 70-80s of the last century. The conclusions are made on the basis of material artifacts obtained during excavations in the 1980s and last 2014-2017. Also presented the results of a joint Uzbek-French archaeological expedition on the survey of archaeological sites in the northern part of the Central Zarafshan oasis. Opinions about the localization of the city are expressed on the basis of written sources and new archaeological materials. On the basis of archaeological excavations, the classification of ceramic products and their interaction with the culture of neighboring territories are analyzed. Kabudanjakent, the Sogdian rustak located in the northern part of Zarafshan, and its pottery show similarities with the early medieval ceramics of Chach, Ustrushona, South and West Sugd regions, as well as the influence of the "Kaunchi" culture
A Spectroscopic Study of Field and Runaway OB Stars
Identifying binaries among runaway O- and B-type stars offers valuable
insight into the evolution of open clusters and close binary stars. Here we
present a spectroscopic investigation of 12 known or suspected binaries among
field and runaway OB stars. We find new orbital solutions for five single-lined
spectroscopic binaries (HD 1976, HD 14633, HD 15137, HD 37737, and HD 52533),
and we classify two stars thought to be binaries (HD 30614 and HD 188001) as
single stars. In addition, we reinvestigate their runaway status using our new
radial velocity data with the UCAC2 proper motion catalogs. Seven stars in our
study appear to have been ejected from their birthplaces, and at least three of
these runaways are spectroscopic binaries and are of great interest for future
study.Comment: 21 pages, 1 figure, 7 tables; Accepted to Ap
THE CONTENT OF STEROID HORMONES IN PATIENTS WITH CHOLELITHIASIS, DEPENDING ON THE DISEASE
Here, in this work, the peculiarities of secretion of steroid hormones have been researched in patients with gallstone disease depending on the course of the disease. It is suggested, that the lack of use of cholesterol for steroidogenesis leads to its precipitation in the composition of gallstones, increased cortisol is a limiting factor in inflammatory processes in the gall bladder. The increasing of testosterone synthesis may be considered as an antagonistic component of glucocorticoid regulation of lipid and protein metabolism
8-Hydroxy-8-phenyl-2,3,7,8-tetrahydro-6H-1,4-dioxino[2,3-f]isoindol-6-one
In the title compound, C16H13NO4, the indole system is essentially planar, whereas the dioxane ring adopts a twist conformation. The molecules are linked into chains by —O— H⋯O=C— hydrogen bonds and these chains are linked into rods by means of N—H⋯O hydrogen bonds. Exept for weak C—H⋯O interactions between the rods, no other intermolecular contacts of interest are present
Trigonal-bipyramidal Anion [Ph2Cl3Sn]- in the Structure of N-[(Diethylphosphoryl)methyl] piperidinium Diphenyltrichlorostannate(IV)
Crystal structure of N-(diethylphosphoryl)methyl-piperidinium diphenyltrichlorostannate(IV), C10H23NO3P+ C12H10Cl3Sn- has been determined, a = 11.416(2), b = 11.582(2), c = 12.491(2) Å, α = 69.82(2), β = 81.22(2), γ = 60.73(2)°, space group P1̅, 4493 reflections, R(F) = 0.0271, wR(F2) = 0.0712. The structure consists of isolated trigonal-bipyramidal anions and hydrogen-bonded dimers formed by cations. The impact of secondary Sn⋅⋅⋅Cl interactions on the geometry of complex anions is discussed
rac-12,14-Dicyclopropyl-5,8,13,18,21-pentaoxapentacyclo[13.8.0.02,11.04,9.017,22]tricosa-1(15),2(11),3,9(10),16,22(23)-hexaene
The molecule of the title compound, C24H24O5, has crystallographic twofold symmetry, with the central O atom lying on the rotation axis. The dihedral angle between the best planes of the benzene rings fused to the oxepine fragment is 38.5 (1)°. The dioxine ring adopts a twist form with the ethylene group C atoms deviating by 0.472 (5) and −0.248 (6) Å from the plane defined by the remaining ring atoms
Stability of the inverse resonance problem on the line
In the absence of a half-bound state, a compactly supported potential of a
Schr\"odinger operator on the line is determined up to a translation by the
zeros and poles of the meropmorphically continued left (or right) reflection
coefficient. The poles are the eigenvalues and resonances, while the zeros also
are physically relevant. We prove that all compactly supported potentials
(without half-bound states) that have reflection coefficients whose zeros and
poles are \eps-close in some disk centered at the origin are also close (in a
suitable sense). In addition, we prove stability of small perturbations of the
zero potential (which has a half-bound state) from only the eigenvalues and
resonances of the perturbation.Comment: 21 page
Эпидемиологические особенности инфекций, связанных с оказанием медицинской помощи в детской кардиохирургии
4—5 congenital heart defect cases per 1000 newborns are diagnosed worldwide. Some malformations require surgical methods of correction. Various risk factors contribute to the development of healthcare associated infections (HAIs). The HAIs are one of the leading causes of the prolongation of hospitalization length both in intensive care unit and in the inpatient departments, and they also play a significant role in increasing the number of lethal outcomes. A number of risk factors play an important role in the development of HAIs: the duration of post-operative mechanical ventilation, neonatal age, low birth weight, co-morbidities, including malformations of other body systems.Врожденные пороки сердца диагностируются в мире в 4—5 случаях на 1000 новорожденных. Часть пороков развития требует хирургических методов коррекции. В связи с высокой подверженностью данной категории пациентов различным факторам риска у них могут развиваться инфекции, связанные с оказанием медицинской помощи. Они являются значимой причиной увеличения продолжительности срока пребывания пациентов как в отделениях реанимации и интенсивной терапии, так и стационаре в целом, а также играют существенную роль в увеличении количества летальных исходов. В развитии инфекций, связанных с оказанием медицинской помощи, важную роль играют следующие факторы риска: длительность послеоперационной искусственной вентиляции легких, возраст менее 30 дней, низкая масса тела ребенка при рождении, наличие сопутствующей патологии, в том числе пороки развития других систем организма
Treatment of cryptorchidism in pediatric surgical practice: a multicenter study
Introduction. Cryptorchidism is a common disease in pediatric urological and andrological practice since the issues of tactical approaches and its optimal treatment remain extremely relevant. Cryptorchidism makes a significant contribution to the structure of male infertility.Objective. To conduct a retrospective analysis of treatment results in children and adolescents with cryptorchidism.Materials & methods. This study summarises the treatment results of 8308 patients with cryptorchidism aged from 6 months to 17 years who underwent inpatient treatment in the Russian Federation and the Republic of Uzbekistan.Results. It was revealed that from 2015 to 2019, patients were admitted for surgical treatment evenly over the years. The ratio of right-sided / left-sided / bilateral cryptorchidism was 4.6 : 4.4 : 1 The inguinal form prevailed more than 6 times over the abdominal location. At the same time, 26.1% of the patients underwent surgery at the optimal time, and 9.8% were older than 10 years. More often, children are operated from an open inguinal access (95.0%), much less often — laparoscopically and percutaneously. Stage-by-stage treatment was carried out in 6.0% of patients.Conclusion. Thus, the approach presented in the study in the surgical treatment of cryptorchidism provided good treatment results. The number of disease relapses was 1.9% (mainly among children over 7 years old). Most surgeons are very reserved about primary orchidectomies (only 3.8% were performed)
