Achieving high efficiency and high torque is an important target in EV motors. This paper describes the effect of the magnetic properties of electrical steels used as core materials for synchronous motors with permanent magnets, which are commonly used as the EV traction motors. It was confirmed that electrical steels, which have high flux density and low iron loss properties can realize high motor efficiency and torque. When PWM excitation is considered, thinner electrical steels are advantageous to suppress increased loss due to higher harmonics. Based on these results, electrical steels having high flux densities and low iron losses at high frequencies were developed.

Abstract We describe a technique for mapping the distribution and concentrations of trace elements, most notably with capabilities of achieving 1-10 parts per million sensitivities within 1 second and at <8 μm resolution. The technique features an innovative, high flux microstructured x-ray source and a new approach to x-ray optics comprising a high efficiency twin paraboloidal x-ray mirror lens. The resulting ability to acquire dramatically higher sensitivities and resolution than conventional x-ray fluorescence approaches, and at substantially higher throughput enables powerful compositional mapping for failure analysis, process development, and process monitoring.

Введение. Расширенные комбинированные вмешательства являются основным методом лечения пациентов с местнораспространенными солидными злокачественными опухолями. Основным следствием масштабной онкохирургии является риск развития острой массивной кровопотери (ОМОК). Цель исследования: оценка переносимости ОМОК у онкологических больных. Материалы и методы. В одноцентровое ретроспективное исследование с января 1999 г. по декабрь 2018 г. были включены 4236 больных, оперированных в радикальном объёме по поводу злокачественных опухолей различных локализаций, течение операции у которых осложнилось ОМОК. Критерием ОМОК являлась потеря ≥ 50% от расчётного объёма циркулирующей крови (ОЦКр) в течение 3 ч операции. Пациенты, вошедшие в исследование, были разделены на 4 группы в зависимости от объёма кровопотери: от 51 до 100%, от 101 до 200%, от 201 до 300% и свыше 300% ОЦКр. Результаты. Пациенты исследованных групп не различались ни по общим показателям, ни по исходному соматическому статусу. Про анализированы качественный и количественный состав инфузионно-трансфузионной терапии (ИТТ), показатели баланса жидкости интраоперационно, продолжительность пребывания пациентов в отделении реанимации и интенсивной терапии, летальность. Заключение. Соблюдение определенного протокола ИТТ при онкологических операциях, осложнённых ОМОК, является залогом успешного лечения и позволяет снизить интраоперационную летальность до 0,8% и госпитальную летальность до 6,45%. Метод аппаратной реинфузии аутоэритроцитов продемонстрировал высокую эффективность. Background. Cancer surgery remains the backbone of treatment approaches in patients with locally advanced solid malignancies. Risk of acute massive blood loss (AMBL) remains the main complication of such large-scale cancer surgery. Objectives: assessment of AMBL tolerance in cancer patients. Patients/Methods. A single- center retrospective study from January 1999 to December 2018 included 4,236 patients who underwent radical surgery for malignant tumors of various localizations, whose course of surgery was complicated with AMBL. The AMBL criterion was the loss of ≥ 50% of the calculated circulating blood volume (СBVс) within 3 hours of the operation. The patients included in the study were divided into 4 groups depending on the volume of blood loss: from 51 to 100%, from 101 to 200%, from 201 to 300% and over 300% of СBVс. Results. Patients of the studied groups did not differ either in general parameters or in baseline somatic status. The qualitative and quantitative composition of infusion-transfusion therapy (ITT), intraoperative fluid balance, patients stay in the intensive care unit, and mortality were analyzed. Conclusions. Compliance with a specific ITT protocol during cancer surgery complicated by AMBL is the key to successful treatment and allows to reduce intraoperative mortality to 0.8% and hospital mortality to 6.45%. The method of intraoperative red cell salvage and autologus transfusion has demonstrated high efficiency.
