Hat, tezhip, ebru, çinicilik, çiltçilik camcılık, lülecilik, mühürcülük, mahyacılık bunlardan bazılarıdır. Yazarın, özellikle hatıralarında ve araştırma-inceleme yazılarında bu sanat kollarını tarihî seyri içinde, oldukça incelikli ve ayrıntılı bir üslupla işlediği görülür. Ayverdi, tevhitçi bir bakış açısıyla yaklaştığı bütün eserlerinde, Türk kültür ve medeniyetini, sanatını, edebî, tarihî ve fikrî olmak üzere çok geniş bir perspektiften ele almıştır. Onun amacı sadece mazinin güzelliklerini yansıtmak değil, ondan aldığı bilgi ve ilhamla geleceğe ışık tutmak, bir anlamda geçmişten geleceğe bir köprü kurmaktır. Yazarın klasik Türk el sanatlarına yaklaşımı da bu doğrultuda şekillenir.

Segundo a Sociedade Brasileira de Queimaduras (SBQ), estima-se que ocorram em torno de 1.000.000 de acidentes por queimaduras ao ano no país. Em nível mundial, segundo a Organização Mundial de Saúde (OMS), as queimaduras estão associadas com altas taxas de morbimortalidade, limitação funcional, desfiguração e estigma social. Estes dados evidenciam a necessidade de investimento constante por parte do sistema de saúde em ações de prevenção e manejo adequado das vítimas de queimaduras. O objetivo desse trabalho é analisar espacialmente e temporalmente o perfil de hospitalizações por queimaduras e corrosões no Brasil nos últimos anos, período correspondente de Janeiro de 2012 a Julho de 2023. O perfil da população mais afetada foram crianças, etnia parda, do sexo masculino, principalmente entre as faixas etárias de 1 a 4 anos, e da região Sudeste e Nordeste. E no que diz respeito aos gastos hospitalares totais por região que a região Sudeste, e a região Nordeste sofreram maior impacto econômico. Nesse sentido, compreende-se a importância de compreender o perfil epidemiológico e os grupos mais suscetíveis a esse tipo de incidente, visando à implementação de medidas preventivas, especialmente dirigidas aos segmentos mais vulneráveis à ocorrência de queimaduras.

Abstract. Local analytical optimal nudging (LAON) is introduced and thoroughly evaluated for assimilating the Advanced Microwave Scanning Radiometer 2 (AMSR2) sea ice concentration (SIC) in the Norwegian High-resolution pan-Arctic ocean and sea ice Prediction System (NorHAPS). NorHAPS is a developing high-resolution (3–5 km) pan-Arctic coupled ocean and sea ice modeling and prediction system based on the HYbrid Coordinate Ocean Model (HYCOM version 2.2.98) and the Los Alamos multi-category sea ice model (CICE version 5.1.2), with the LAON for data assimilation. In this study, our focus is on the LAON assimilation of AMSR2 SIC, which is designed to update the model SIC in every time step such that the analysis will eventually reach the optimal estimate. The SIC innovation (observation minus model) is designed to be proportionally distributed to the multiple sea ice categories. A hindcast experiment is performed with and without the LAON assimilation for the period 1 January 2021 to 30 April 2022, in which the extra computational cost for the LAON assimilation is about 5 % of the free run without assimilation. The results show that the LAON assimilation greatly improves the simulated sea ice concentration, extent, area, thickness, and volume, as well as the sea surface temperature (SST). It also produces significantly more accurate sea ice edge and marginal zone (MIZ) than the observed AMSR2 SIC that is assimilated when evaluated against the Norwegian Ice Service (NIS) ice chart. The results are also compared with the Copernicus Marine Environment Monitoring Service (CMEMS) operational SIC analyses from NEMO, TOPAZ4, and neXtSIM, which use ensemble Kalman filters and direct insertion for data assimilation. It is shown that the LAON assimilation produces significantly lower integrated ice edge error (IIEE) and integrated MIZ error (IME) than the CMEMS SIC analyses when evaluated against the NIS ice chart. LAON also produces a continuous and smooth evolution of sub-daily SIC, which avoids abrupt jumps often seen in other assimilated products. This efficient and accurate method is promising for data assimilation in global and high-resolution models.

The results of a study on the effect of temperature on the properties of the mandrel and punch during hot screw rolling and subsequent stamping of 1000 pieces are presented. vessels made of medium-carbon structural steel on the rolling and pressing line of the machine-building enterprise BF JSC NPO Pribor. It is established that the main reason for stopping the technological cycle of production and reducing the quality of the geometric dimensions of rolled products is a change in the mechanical properties of the deforming tool. A significant (more than 250 degrees) temperature change along the length of the piercing and pressing tool made of 4X5MFS steel during hot pressure treatment was revealed. The main reasons leading to the deterioration of its quality indicators have been established: the loss of strength and hardness and the increase in plasticity of the sewing mandrel up to 30%, and the punch up to 19%. Rational ways have been identified that will ensure an increase in the service life of the most loaded processing tool, which will lead to a reduction in the cost of vessels at the outlet of the rolling and pressing line by 3–5%.

Представлены результаты структурных исследований и оценки уровня прочности при изгибе сплава на основе алюминида никеля (ВКНА-1В), полученного электроискровым спеканием механоактивированных порошков исходных компонентов при различных режимах спекания. Основным меняющимся параметром являлась температура спекания (от 1100 до 1250 °C). Установлено, что при температуре спекания свыше 1200 °C происходит образование жидкой фазы. Рентгенофазовым анализом в исследуемых материалах выявлена основная фаза – Ni3Al. Рекомендуемым режимом спекания с целью получения плотной малодефектной заготовки из сплава ВКНА-1В является нагрев при температуре спекания 1150 °С с выдержкой, составляющей 5 мин, и приложенным давлением – 40 МПа. Материал такого типа обладает повышенным уровнем предела прочности при изгибе при комнатной температуре σизг = 1640 МПа и микротвердостью, равной 650 HV.

The main variable parameter was the sintering temperature (from 1100 to 1250 °C). It has been established that the sintering temperature above 1200 °C, the formation of a liquid phase occurs. X-ray diffraction analysis in the studied the main phase, Ni3Al, was identified in the materials. The recommended sintering mode in order to obtain a dense, low-defect billet made of VKNA-1V alloy is heating at a sintering temperature of 1150 °C with an exposure of 5 minutes and an applied pressure of 40 MPa. This type of material has an increased level of the ultimate bending strength at room temperature (1640 MPa) and a microhardness equal to 650 HV.

The work is devoted to an actual topic related to the creation of a cryogyroscope rotor with a superconducting niobium coating. The use of a superconducting coating makes it possible significantly improve the orientation accuracy of moving object in space. The electrometallurgical processes necessary for obtaining a superconducting niobium coating on a cryogyroscope rotor were considered. An electrochemical installation for deposition of electrolytic coatings on spherical substrates has been created. An original design of the cathode was proposed, which makes it possible to obtain smooth continuous coatings of niobium on spherical samples. The electrodeposition of niobium coatings on carbopyroceram rotors was carried out by galvanostatic electrolysis from a melt of the composition NaCl–KCl–NaF(10 wt.%)–K2NbF7(8 wt.%)–Nb at a temperature of 750 °C. The conditions for electrodeposition of niobium coatings were chosen. A unit for electrochemical polishing of niobium has been created. The parameters of electrochemical polishing of niobium coatings on spherical samples in the H2SO4:HF (9:1) electrolyte were determined. A protective electrically insulating layer of niobium pentoxide was obtained on rotors with niobium coating by anodic oxidation in a 1% solution of phosphoric acid. The modes of potentiostatic electrolysis for the oxidation of spherical samples have been established.
