Magnetron sputtering is known for years as a powerful tool for coating deposition of cutting tools and machine parts. However the experimental measurements of the magnetron discharge parameters are still necessary to provide a consumer of the magnetron system with the reliable characteristics. A voltage-current relation is the most applied characteristic of the discharge, and it is described as the power low of a type U = U0 + aIn, where U and I are the voltage drop and the discharge current, respectively, and U0 and n are constant. First part of the research is dedicated to the experiments conducted in the magnetron setup provided with the titanium cathode in a vacuum chamber filled with argon or argon-nitrogen mixture, and the constants are determined for the particular geometry of the magnetron sputtering system. The obtained results can be used to choose the operation modes for the traditional applications of the magnetron discharge such as ion cleaning and heating of the non-magnetic workpieces arranged on the cathode, as well as for the sputtering deposition of the titanium and titanium nitride coatings on the surfaces of the workpieces located above the magnetron cathode. In the next part of the research the novel application of the magnetron for production of carbon nanostructures is considered. For the purpose, a layer of expanded graphite is arranged on the magnetron cathode, and the discharge is initiated in oxygen atmosphere. It was found that for the time interval of a few hours the discharge is described as a superposition of the typical magnetron glow with arc spot generation, and the intensity of the arcs is not decreased with time. At that, the arc initiation was accompanied with the formation of clusters of the graphite cathode. The process is explained in terms of the cathode spot generation at the interaction of the arc plasma with the non-melting material. This process can be beneficial for the development of the plasma reactors for the large-scale production of the carbon species at the low gas pressures suitable for the magnetron discharge operation. Thus, the magnetron sputtering systems provided with the expanded graphite cathode can be considered as the tool to grow carbon nanospecies in the arc discharge cathode spots.

Published: December 2020

Este estudo investigou a solução de problemas de estrutura aditiva de 3 estudantes dos anos iniciais do ensino fundamental, a partir de uma lista de problemas e de uma entrevista sobre as soluções. Os dados obtidos foram apresentados de acordo com as categorias: envolvimento na atividade, elaboração de estratégias próprias, construção e manipulação de representações múltiplas e compreensão conceitual. Tais categorias emergiram dos pressupostos da Teoria da Aprendizagem Significativa. A análise dos protocolos não conseguiu evidências de que os estudantes tenhamaprendido de maneira significativa o conceito de adição, uma vez que não conseguiram solucionar, de modo satisfatório, a maioria dos problemas. Os resultados parecem indicar que devemos evoluir das práticas de transmissão de informações e utilização mecânica da memória, para práticas que privilegiem a construção dos conhecimentos, juntamente com o desenvolvimento de atitudes ehabilidades para solucionar problemas, considerando uma variedade de situações, os conhecimentos prévios e as experiências culturais de nossos estudantes.

ОДОНТОЛОГИЯ СРЕДНЕВЕКОВОГО НАСЕЛЕНИЯ БЕЛАРУСИ
Authors: Лейбова Наталья Александровна 
Published: December 2020

В статье представлен новый материал по одонтологии средневекового и близкого к современности населения Беларуси. Основой для исследования послужили краниологические серии c территории г. Несвижа (Минская обл.), приуроченные к Костелу Божьего Тела. Одна из них была получена в ходе спасательных археологических работ на территории кладбища XVII–XVIII вв. у стен костела (55 индивидов), вторая – в ходе реставрационных работ в крипте. В поисках сравнительных материалов c территории Беларуси были также изучены две серии, характеризующие население г. Полоцка (Витебская обл.): серия XIII–XIV вв. c территории Нижнего замка (27 индивидов) и XVII–XVIII вв. c территории Полоцкого городища (41 индивид). Было установлено, что население, захороненное на кладбище при костеле Божьего тела в г. Несвиже и в крипте этого костела относится к кругу грацильных типов, однако в первом случае отчетливо выражены черты северного грацильного типа, во втором – мы можем говорить о присутствии некоего южного компонента в составе погребенных. В населении г. Полоцка мы можем констатировать гораздо более отчетливые различия между ранней и поздней выборками, выразившиеся в отнесении этих групп к двум разным одонтологическим типам: северному грацильному и среднеевропейскому.
The article presents new material on the odontology of the medieval and near-modern population of Belarus. The study is based on craniological samples from the city of Nesvizh (Minsk region). The first one was obtained during the rescue archaeological works at the 17th–18th centuries cemetery at the walls of the Corpus Christi Church (55 individuals), the second one – as a result of restoration works in the crypt of the church. Two samples of the population of Polotsk (Vitebsk Region) were also studied as comparative materials from the territory of Belarus: the 13th–14th centuries sample from the Lower Castle (27 individuals) and the 17th–18th centuries sample from the Polotsk settlement (41 individuals). It was found that the populations buried in the cemetery at the Corpus Christi Church in the city of Nesvizh and in the crypt of this church are rather gracile, although in the first case the features of the northern gracile type are clearly expressed, and in the second case the southern component is observed. In the population of Polotsk, we can see much more distinct differences between early and late samples, expressed in the classification of these groups to two different odontological types: the northern gracile and the central European.

Published: December 2020

BackgroundThe exact biological role of PCOLCE was not yet clear and there were few reports study the correlation of PCOLCE gene expression level with the occurrence and development of gastric cancer.MethodsThe expression of PCOLCE was analyzed by performing the Oncomine and Ualcan database. We evaluated the function of PCOLCE on clinical prognosis with the use of Kaplan–Meier plotter database. The relationship between PCOLCE and cancer immune in filtrates was researched by Tumor Immune Estimation Resource (TIMER) site database.ResultsPCOLCE significantly upregulated in gastric cancer patients compared to normal gastric samples. And the increased expression of PCOLCE mRNA was closely linked to shorter overall survival (OS), progress-free survival (PFS) in all gastric cancers. Besides, PCOLCE expression displayed a tight correlation with infiltrating levels of macrophages and dendritic cells (DCs) in gastric cancer. Moreover, PCOLCE expression was positively correlated with diverse immune marker sets in gastric cancer.ConclusionAll the results above suggested that overexpression of PCOLCE indicated unfavorable prognosis in patients with gastric cancer. PCOLCE was correlated with immune infiltrating levels including those of B cells, CD8 + T cells, CD4 + T cells, macrophages, neutrophils, and DCs in gastric cancer patients. All the findings suggested that PCOLCE could be used as a prognostic biomarker for determining prognosis and immune infiltration in gastric cancer. Additionally, PCOLCE expression potentially contributed to the regulation of monocyte, M2 macrophage, Tfh, CD8 + T cell, TAM, Th1 cell Thus PCOLCE is a potential target for gastric cancer therapy and these preliminary findings require further study to determine whether PCOLCE-targeting reagents might be developed for clinical application in gastric cancer.

Published: December 2020

BackgroundPostherpetic neuralgia (PHN) is a form of long-lasting neuropathic pain that can severely affect patients’ quality of life. Pulsed radiofrequency (PRF) has been proven to be effective in treating PHN, but the optimal radiofrequency parameters are still not well defined. This retrospective study aimed to compare the efficacy and safety of CT-guided PRF at three different voltages for the treatment of PHN patients.MethodsThis study included 109 patients with PHN involving the thoracic dermatome who were treated in the Department of Pain Management of Shengjing Hospital, China Medical University, from January 2017 to May 2019. They were divided into three groups based on the PRF voltage used: group A (45 V), group B (55 V), and group C (65 V). The PRF therapy (voltage 45, 55, and 65 V) was performed in all patients by targeting the thoracic dorsal root ganglion. After surgery, patients were followed at 3 days, 1 month, 3 months, 6 months, and 12 months. Observation at each follow-up included basic patient characteristics, visual analog scale (VAS), 36-Item Short Form Health Survey (SF-36) scores, patient satisfaction, complications, and side effects.ResultsVisual analog scale scores decreased and SF-36 scores increased for all patients in the three groups at each post-operative time point (1, 3, 6, and 12 months; allP&lt; 0.01). Pain relief, improvement in quality of life, and overall satisfaction were more significant for patients in group C than for those in groups A and B at the 3-, 6-, and 12-month follow-ups (allP&lt; 0.05). Patients in group B had lower VAS scores and higher overall satisfaction levels than those in group A (bothP&lt; 0.01). A small number of patients from each group (n≤ 3) experienced mild intraoperative and post-operative complications, which bore no relationship with group assignment (allP&gt; 0.05). At post-operative day 3, patients in group C had skin numbness affecting a larger area than patients in the other two groups (bothP&lt; 0.05), but the differences were no longer statistically significant at day 30 after the operation. All patients experienced a drop in numbness area of more than 30% after surgery.ConclusionCompared with PFR at 45 and 55 V, PFR at 65 V had superior efficacy in treating PNH, with a favorable safety profile.

Published: December 2020

ObjectiveWe retrospectively evaluated the oncological and functional effectiveness of revision surgery for recurrent or remnant vestibular schwannoma (rVS).MethodsWe included 29 consecutive patients with unilateral hearing loss (16 women; mean age: 42.2 years) that underwent surgery for rVS. Previous surgeries included gross total resections (GTRs, n=11) or subtotal resections (n=18); mean times to recurrence were 9.45 and 4.15 years, respectively. House–Brackmann (HB) grading of facial nerve (FN) weakness (grades II-IV) indicated that 22 (75.9%) patients had deep, long-lasting FN paresis (HB grades: IV-VI). The mean recurrent tumor size was 23.3 mm (range: 6 to 51). Seven patients had neurofibromatosis type 2.ResultsAll patients received revision GTRs. Fourteen small- to medium-sized tumors located at the bottom of the internal acoustic canal required the translabyrinthine approach (TLA); 12 large and small tumors, predominantly in the cerebellopontine angle, required the retrosigmoid approach (RSA); and 2 required both TLA and RSA. One tumor that progressed to the petrous apex required the middle fossa approach. Fifteen patients underwent facial neurorrhaphy. Of these, 11 received hemihypoglossal–facial neurorrhaphies (HHFNs); nine with simultaneous revision surgery. In follow-up, 10 patients (34.48%) experienced persistent deep FN paresis (HB grades IV-VI). After HHFN, all patients improved from HB grade VI to III (n=10) or IV (n=1). No tumors recurred during follow-up (mean, 3.46 years).ConclusionsAggressive microsurgical rVS treatment combined with FN reconstruction provided durable oncological and neurological effects. Surgery was a reasonable alternative to radiosurgery, particularly in facial neurorrhaphy, where it provided a one-step treatment.
