Use of accelerated helium-3 ions for determining oxygen and carbon impurities in some pure materials

Methods are developed for the determination of O impurity in Be and Si carbide and concurrent determination of C and O impurities in Si and W by irradiation with accelerated He-3 ions and subsequent activity measurements of C-11 and F-18 formed from C and O with the aid of a gamma-gamma coincidence spectrometer. Techniques for determining O in Ge and Ga arsenide with radiochemical separation of F-18 are also described

Оценка аспектов устойчивого развития в деятельности транспортных компаний

Managing a company's sustainable development has an impact not only on internal processes, but also on interaction with suppliers and improvement of the system of responsible supply chain management. In this regard, it becomes necessary for transport companies as providers of logistics services to pay attention to compliance with sustainability criteria so that cooperation with them has a positive effect on the reputation and positions in customer sustainability rankings. This paper examines the criteria for evaluating the maturity of practices implemented by a logistics service provider for large manufacturing companies in relation to their environmental and social impact. The relevance of the work lies in the need to create tools for assessing the level of sustainable development of companies in the transport industry and develop recommendations for industry-wide standards.The results of the study might be of interest to managers and specialists of logistics companies and employees of transport universities in view of special importance of high-quality education for achieving sustainable development goals. Управление устойчивым развитием компании оказывает влияние не только на внутренние процессы, но и на взаимо­действие с поставщиками и совершенствование системы ответственного управления цепочкой поставок. В этой связи перед транспортными компаниями как поставщиками логистических услуг возникает необходимость уделять внимание соответствию критериям устойчивого развития, чтобы сотрудничество с ними положительно влияло на репутацию и позиции в рейтингах устойчивого развития клиентов. В данной работе рассмотрены критерии оценки зрелости практик, внедряемых поставщиком логистических услуг для крупных производственных компаний в отношении их экологического и социального воздействия. Актуальность работы заключается в необходимости сформировать ин­струменты для оценки уровня устойчивого развития компа­ний транспортной отрасли и выработки рекомендаций для общеотраслевых стандартов.Результаты исследования представляют интерес для руководителей и специалистов логистических компаний и для работников транспортных вузов в виду особой значи­мости качественного образования Для достижения целей устойчивого развития.

Solution-processed flexible broadband ZnO photodetector modified by Ag nanoparticles

In this work, we present flexible broadband photodetectors (PDs) fabricated by a deposition of nanostructured zinc oxide (ZnO) films on polyimide (PI) substrates by using cheap and scalable aqueous method Successive Ionic Layer Adsorption and Reaction (SILAR). In order to increase the long-wavelength absorption of the nanostructured ZnO layer, we created its intrinsic defects, including oxygen vacancies by post-treatment at 300 °C in vacuum and thus the light-sensitive material ZnO/PI was obtained. Then we applied silver nanoparticles (Ag NPs) from a silver sol onto a nanostructured ZnO film, which were visualized using SEM in the form of spheres up to 100 nm in size that increased the photocurrent and figures of merit of thus obtained light-sensitive material ZnO_Ag/PI due to localized surface plasmon resonance and double Schottky barriers at the Ag-ZnO interface. To fabricate photodetectors based on a photoconductive effect, these ZnO/PI and ZnO_Ag/PI materials were equipped with ohmic aluminum contacts. The spectral responsivity (Rλ up to 275 A/W to UV light) of solution-processed flexible broadband photodetector based on ZnO_Ag/PI material at different wavelengths of light and light power densities is better than Rλ of the ZnO/PI photodetector, and at least an order of magnitude higher than Rλ of photodetectors based on nanostructured zinc oxide described in recent articles. The external quantum efficiency (EQE) of both PDs in this study in UV–Vis-NIR spectra is very high in the range from 1∙102 to 9∙104 % and is better or of the same order of magnitude as the EQE data of modern flexible broadband high-sensitivity PDs based on nanostructured heterostructures containing ZnO. The specific detectivity in UV–Vis-NIR spectra is large for ZnO/PI (from 3.5∙1010 to 1∙1012 Jones) and especially for ZnO_Ag/PI (from 1.6∙1011 to 8.6∙1013 Jones), which indicates the ability of the PDs based on light-sensitive materials ZnO/PI and ZnO_Ag/PI to recognize a very weak light signal

Анализ причин поздней диагностики туберкулеза легких

A pilot study was designed to analyze causes of late diagnosis of lung tuberculosis and late start of the specific therapy. Thirty-eight inpatients with proven infiltrative lung tuberculosis were randomly involved in the study; they were city and rural dwellers of different age. A special questionnaire was developed to determine reasons of late diagnosis. An analysis of results obtained has shown that 8 patients, or 21 % were diagnosed at a scheduled large frame photofluorography, 30 % of the late diagnosed patients were not aware of their disease, 25 % of the females and 64 % of the maleswere self-treated. Primary care therapeutists were blamed for the late diagnosis in 33 % of the patients while failed to perform necessary investigations; the delay was 2 to 11 months.Было проведено пилотное исследование по анализу причин отсрочки установления диагноза туберкулез легких (ТЛ) и начала специфической терапии. Методом случайной выборки было взято 38 пациентов с подтвержденным диагнозом инфильтративный ТЛ, проходивших курс стационарного лечения, жителей городской и сельской местности, различного возраста. Для установления причин отсрочки была разработана специальная анкета. Анализ порученных результатов показал, что у 8 пациентов (21 %) патология была выявлена при плановой ККФ. 30 % пациентов с отсрочкой диагноза не располагают информацией о туберкулезе, 25 % женщин и 64 % мужчин проводили самолечение. У 33 % обследованных отсрочка диагноза и начала лечения произошла по вине участкового терапевта, из-за невыполнения диагностического минимума обследования на туберкулез, она составила от 2 до 11 месяцев
