Published: February 2024

The aim. To study and summarize modern immunological methods of laboratory diagnosis of the causes of infertility.
Materials and methods. An analytical review and analysis of the scientific literature in recent years, covering the study of immunological causes of infertility and, accordingly, the use of immunological methods of diagnosis and treatment of infertility.
Results and discussion. Infertility treatment is an urgent medical problem because, according to the WHO, every sixth person faces this problem during their lifetime. Immunological aspects play an important role in infertility and account for 5% of infertility among men and women. In cases where the cause of infertility cannot be explained by the presence of specific organic signs in a couple, the identification of immunological mechanisms of infertility becomes more crucial. The immunological causes of infertility are still underestimated, as the mother’s immune system plays a major role in the successful implantation of the embryo and the carrying of a pregnancy. The relevant areas of immunological research are HLA typing to determine the immunological «compatibility» of couples, the study of the role of antisperm antibodies (ASA) in the development of infertility, and the use of exosomes as biomarkers of reproductive system diseases that may be the cause of infertility. In accordance with the material reviewed, we have identified the main areas of research into the causes, diagnosis, and treatment of infertility, which require further detailed study for the successful overcoming of infertility in the future.
Conclusion. We have reviewed the articles that included materials on the study of immunological methods of infertility research and identified three currently relevant methods for identifying the causes and diagnosis of this disease, which continue to require thorough study to solve the problems of infertility. Carriage of the HLA-DQA1*5 allele can be used as a marker of the degree of HLA-DQA1 compatibility of a couple, as well as the use of some exosome markers, such as endometriosis-specific exosome characteristics such as miR-214-3p, EVLGMNP1, AFAP1-AS1. There is also no doubt that there is a high correlation between elevated levels of ASA and female infertility, so special attention should be paid to ASA in the diagnosis of male infertility.

Cet article met en évidence la répartition saisonnière des précipitations dans le bassin versant de Beni-Bahdel, et son impact sur les écoulements de surface et les transports solides en suspension. Pour ce faire, nous avons exploité les données météorologiques, les débits liquides et les concentrations de matières en suspension fournies par l’Agence Nationale des Ressources Hydriques (ANRH) sur une période de 46 ans (1972-2018). En considérant uniquement les écoulements de surface, nous avons établi les relations directes entre les précipitations et les débits liquides et entre les précipitations et les transports solides pour mettre en évidence l’impact saisonnier des précipitations sur l’érosion et les ruissellements de surface. Les résultats obtenus dans ce travail montrent que les pluies automnales et estivales provoquent directement l’érosion des versants induisant des concentrations en MES importantes à l’exutoire du bassin versant. En hiver et au printemps, elles contribuent aux écoulements de surface tout en apportant des flux d’eau significatifs au barrage. Les calculs basés sur une modélisation linéaire montrent qu’en moyenne 1 mm de pluie génère 0,031 Hm3 d’écoulement à l’exutoire du bassin et 14 x 103 tonnes de transports solides en automne, alors qu’au printemps, il provoque 0,063 Hm3 d’écoulement et 1,64 x 103 tonnes de matières en suspension.

Показана возможность получения методом самораспространяющегося высокотемпературного синтеза под давлением азота сплошных слитков (без газовой пористости) стали системы Fe–Cr–Mn–Mo–Al–Mg–N–C с равномерно распределенными по объему аустенитной матрицы, стабилизированной азотом, дисперсными армирующими включениями, представляющими собой конгломераты, в центре которых сконцентрированы оксиды магния с примесями оксидов алюминия, вокруг которых располагаются нитриды алюминия. Исследован структурно-фазовый состав данной стали в литом состоянии и после термической обработки при 1250 °C в течение 2 ч с последующей закалкой в воду. Выявлено снижение твердости образцов в результате проведения гомогенизирующей термической обработки с 389 HV до 271 HV. При этом у термообработанного образца микротвердость матрицы на 40 HV ниже общей твердости образца, что демонстрирует армирующее действие обнаруженных равномерно распределенных дисперсных включений.
He possibility of obtaining solid ingots (without gas porosity) of steel of the Fe–Cr–Mn–Mo–Al–Mg–N–C system by the method of selfpropagating high-temperature synthesis under nitrogen pressure is shown. The structure of this ingot consists of a high nitrogen austenitic matrix; in it, dispersed reinforcing inclusions are evenly distributed over the volume. These inclusions are conglomerates, in the center of which magnesium oxides are concentrated with impurities of aluminum oxides, and around which aluminum nitrides are located. The structural-phase composition of this steel was studied in the cast state and after heat treatment at 1250 °C for 2 hours followed by water quenching. A decrease in the hardness of the samples after homogenizing heat treatment was revealed: from 389 HV to 271 HV. In this case, the microhardness of the matrix in the heat-treated sample is 40 HV lower than the total hardness of the sample. This demonstrates the reinforcing effect of the detected uniformly distributed dispersed inclusions.

Представлена методика расчета линейной усадки сляба при его формировании на технологической линии МНЛЗ, с помощью которой выполнено моделирование процесса усадки сляба толщиной 250 и 315 мм, разливаемых при рабочих скоростях 1,0 и 0,6 м/мин, соответственно. В результате моделирования выявлены закономерности влияния содержания углерода в стали на относительную усадку сляба на всем протяжении технологической линии МНЛЗ. С помощью полученных закономерностей установлено комплексное влияние содержания углерода на величину усадки, в частности, наибольшая усадка характерна для перитектической стали с содержанием углерода 0,16%, по сравнению как с меньшим, так и с большим содержанием углерода. Полученные зависимости могут быть использованы технологами для оценочного подбора параметров настройки роликовой проводки МНЛЗ.
A method for calculating the linear shrinkage of a slab during its formation on a CCM production line is presented. With the help of that the simulation of the process of shrinkage of a slab with a thickness of 250 and 315 mm cast at operating speeds of 1.0 and 0.6 m/min respectively is performed. As a result of modeling, regularities of the affecting of carbon content in steel on the relative shrinkage of the slab throughout the entire length of the CCM production line were revealed. Due to the regularities obtained, a complex effect of the carbon content on the amount of shrinkage was established, in particular, the highest shrinkage is a characteristic of peritectic steel with the carbon content of 0.16%, compared with both lower and higher carbon contents. The obtained dependences can be used by technologists for the estimated selection of the parameters for setting the CCM roller guide.

Published: February 2024

Снижение интенсивности интеграционных процессов в металлургии и машиностроении, связанное как с текущими геополитическими особенностями конъюнктуры мирового рынка, так и с неравномерностью производства, распределения и потребления конечного металлоизделия, определяет необходимость поиска энерго- и материалоэффективных технологических направлений, обеспечивающих стабильную загрузку и развитие предприятий. К числу таких технологических направлений следует отнести разработку вариантов получения слоистого композита, состоящего из металлов и сплавов, имеющих существенные отличия в наборе свойств. Формированием биметаллических конгломератов достигаются цели получения композитного металлопродукта с набором уникальных характеристик, сочетающим в себе, например, высокую механическую прочность сплава, из которого сформирована основа, стойкость к абразивному износу, сопротивляемость коррозии, электро- и теплопроводность металла покрытия. Проблема, препятствующая более широкому распространению технологий формирования биметаллических изделий, – неоднородность контактирующих сплавов по химическому и фазовому составу, в ряде случаев, приводящая к электрохимической коррозии незащищенных участков, а также к невысокой прочности зоны контакта разнородных материалов. В работе приведены результаты анализа причин формирования указанных выше проблем биметаллических соединений, рассмотрены перспективные методы получения металлокомпозитов и повышения их характеристик.
The decrease in the intensity of integration processes in metallurgy and mechanical engineering, associated with both the current geopolitical features of the global market situation and the uneven production, distribution and consumption of final metal products, determines the need to search for energy- and material-efficient technological directions that ensure stable utilization and development of enterprises. Such technological directions include the development of options for obtaining a layered composite consisting of metals and alloys with significant differences in the set of properties. By forming bimetallic conglomerates, the goals of obtaining a composite metal product with a set of unique characteristics are achieved, combining, for example, high mechanical strength of the alloy from which the base is formed, resistance to abrasive wear, corrosion resistance, electrical and thermal conductivity of the coating metal. The heterogeneity of contacting alloys in chemical and phase composition, in some cases, leading to electrochemical corrosion of unprotected areas, as well as low strength of the contact zone of dissimilar materials, is a problem that prevents the wider spread of technologies for the formation of bimetallic products. The paper presents the results of the analysis of the causes of the formation of the above-mentioned defects of bimetallic compounds, discusses promising methods for obtaining metal composites and improving a number of their characteristics.
Fetal - maternal hemorrhage: A comparison of two cases
Authors: Nga Nguyen Thi Quynh , Ninh Phan Thi Huyen , Nguyen Pham Thao 
Published: February 2024

Almost all pregnancies have only a small amount of fetal blood in maternal circulation. In some rare cases, massive fetal-maternal hemorrhage can result in rapid fetal hemodynamic collapse, leading to severe fetal morbidity and mortality. Unfortunately, fetal – maternal hemorrhage is rarely diagnosed prenatally because clinical manifestations are often nonspecific, subtle, and difficult to identify at the time of the event. In this article, we present two cases of large fetal-maternal hemorrhage which were proven by the Kleihaure-Betke test to highlight the difference between nonspecific initial manifestations and the outcome of each case. Moreover, we would like to emphasize the importance of early detection and timely treatment to prevent potentially devastating complications of this condition.

The study was conducted to assess the immunostimulatory effect of Hericium Erinaceus on cyclophosphamide-induced immunodeficient mice. Animals were administered Hericium Erinaceus orally at 0.72 g/kg b.w and 1.44 g/kg b.w for seven consecutive days. On the 4th day, CP (200 mg/kg) was intraperitoneally injected into mice. The results illustrated that Hericium Erinaceus at 0.72 g/kg b.w only posed an immunostimulating potency in the cyclophosphamide-induced immunosuppression model. Besides, Hericium Erinaceus at 1.44 g/kg b.w ameliorated the effects of CP on delayed-type hypersensitivity (DTH) response, relative spleen weight, serum IL-2, TNF-α concentration, and micro-histological images of spleen and thymus substantially. This suggested the potential of Hericium Erinaceus to treat immunosuppression diseases in clinical practice.

Geology of the Beryllium-Rare Earth Element Deposits at Sierra Blanca,
West Texas

Published: February 2024

Abstract
Beryllium ore is hosted by fluorspar deposits at Round Top, one of five rhyolite laccoliths exposed approximately 120 km southeast of El Paso, just north of Interstate Highway 10 and just west of the town of Sierra Blanca, in Trans-Pecos Texas (Fig. 1). The fluorspar deposits occur within the mid-Cretaceous Buda Limestone, which is intruded by the rhyolite, and weakly extend into the rhyolite as well (Fig. 2). Cyprus Beryllium Corporation, sole operator of the property, lists reserves and resources of 850,000 tons of ore averaging 1.5 wt% BeO (25 million pounds BeO; H. Harlan, written comm., 1990). The magma that formed Round Top was highly enriched in Li, Be, F, Zn, Rb, Y, Zr, Nb, Sn, Cs, rare earth elements (REEs, especially heavy REEs- [HREEs]), Pb, Th, and U (Rubin et al., 1987; Price et al., in press). In fact; the Round Top intrusion, the most rareelementenriched of the five laccoliths, could be considered a high-tonnage, low-grade resource for several rare metals. For example, the average Th content of the Round Top rhyolite (180 ppm) is almost four times that of the Conway Granite (New Hampshire), which has been considered a hightonnage resource of Th (Finch et al., 1973). The fluoritized samples show complementary enrichment in many of the abovementioned incompatible elements as well as Na, AI, Ti, V, and As. The enriched elements, including Be, are present either in discrete minerals or, particularly in the case of the REEs, in solid solution in fluorite.
