Improvement of calculation method for electrical parameters of short network of ore-thermal furnaces

The paper describes new method of calculation for active and inductive resistance of split interleaved current leads packages in ore-thermal electric furnaces. The method is developed on basis of regression analysis of dependencies of active and inductive resistances of the packages upon their geometrical parameters, mutual disposition and interleaving pattern. These multi-parametric calculations are performed with ANSYS software. Proposed method allows solving problems of minimization and balancing of electrical parameters of split current lead in ore-thermal furnaces

Non-chemical addictions in the student environment: an example of gadget addiction

One of the important problems in the modern world is the growing non-chemical addiction, which includes: gadget addiction, computer addiction, Internet addiction, addiction to social networks, and others. The most common of these is gadget addiction, a social phenomenon characterized by the abuse of gadgets. The aim of the study was to identify signs of gadget addiction among medical students. To achieve the goal, 426 people were interviewed using the questionnaire method. The questionnaire is based on the "Scale for assessing dependence on a personal computer, the Internet and mobile devices that provide access to it." The scores scored by the scales were grouped into 4 subscales, and, depending on a certain amount, one could talk about the signs of gadget addiction in an individual. Signs of gadget addiction were found in 25.8% of students.Одной из важных проблем в современном мире является набирающая силу нехимическая зависимость, к которой относятся гаджетозависимость, компьютерная зависимость, интернет-зависимость, зависимость от социальных сетей и другие. Наиболее распространенная из них — гаджетозависимость — социальное явление, характеризующееся злоупотреблением использования гаджетами. Целью исследования стало выявление признаков гаджетозависимости у студентов медицинского университета. Для достижения цели было опрошено 426 человек методом анкетирования. В основу опросника вошла «Шкала оценки зависимости от персонального компьютера, интернета и мобильных устройств, обеспечивающих доступ к нему». Набранные по шкалам баллы группировались в 4 субшкалы, и в зависимости от определенной суммы можно было говорить о признаках гаджетозависимости у отдельного человека. Признаки гаджетозависимости выявлены у 25,8% студенто

A clinical description of two cases of orphan diseases in newborns in the intensive care unit

Clinical cases of the leucinosis and Shwachman-Diamond syndrome at newborns, who were in a serious condition in intensive care unit are described. The clinical picture of diseases and steps of diagnostic search are given. The diagnosis «leucinosis» was made at the age of 2 months that led to belated beginning of specific treatment and adversely affected the disease prognosis. The diagnosis of a syndrome of Shvakhman-Daymond was not established intravital because of rarity of this pathology, weak knowledge of pediatricians and comorbid diseases of the patient.В статье описаны клинические случаи лейциноза(ОМ1М #248600) и синдрома Швахмана-Даймонда (0М1М #260400) у новорожденных, получавших лечение в отделении реанимации и интенсивной терапии. Приведены клиническая картина заболеваний и этапы диагностического поиска. Диагноз «лейциноз» был поставлен в возрасте 2 месяцев, что привело к позднему началу специфического лечения и неблагоприятно отразилось на прогнозе. Диагноз синдрома Швахмана-Даймонда не был установлен при жизни пациента в виду редкости данной патологии, слабой информированности специалистов и наличия у больного коморбидных заболеваний

Diagnosis of microaspiration syndrome in children with bronchial asthma using non-invasive methods

For the purpose of identification of a microaspiration syndrome among children as a possible reason of development of bronchial asthma we suggested a number of noninvasive methods: questioning, lactose identification, average capacity of lipophages in the induced sputum of a bronchial tree within 21 patients from 10 to 17 years. The conducted research resulted in 38% of children with bronchial asthma had a high probability of having of a microaspiration syndrome. The recommended research methods have been proved efficient.С целью выявления микроаспирационного синдрома у детей, как возможной причины развития бронхиальной астмы нами были предложены ряд неинвазивных методов: анкетирование, выявление лактозы, средняя нагруженность липофагов в индуцированной мокроте бронхиального дерева у 21 пациента от 10 до 17 лет. В результате проведенного исследования 38% детей с бронхиальной астмой имели высокую вероятность наличия синдрома микроаспирации. Была доказана эффективность предложенных методов исследования

High-Precision U-Pb Zircon Age Calibration of the Global Carboniferous Time Scale and Milankovitch Band Cyclicity in the Donets Basin, Eastern Ukraine

High-precision ID-TIMS U-Pb zircon ages for 12 interstratified tuffs and tonsteins are used to radiometrically calibrate the detailed lithostratigraphic, cyclostratigraphic, and biostratigraphic framework of the Carboniferous Donets Basin of eastern Europe. Chemical abrasion of zircons, use of the internationally calibrated EARTHTIME mixed U-Pb isotope dilution tracer, and improved mass spectrometry guided by detailed error analysis have resulted in an age resolution o

Paediatric Home Artificial Nutrition in Italy: Report from 2016 Survey on Behalf of Artificial Nutrition Network of Italian Society for Gastroenterology, Hepatology and Nutrition (SIGENP)

Home Artificial Nutrition (HAN) is a safe and efficacious technique that insures children's reintegration into the family, society and school. Epidemiological data on paediatric HAN in Italy are not available. Aim: to detect the prevalence and incidence of Home Parenteral Nutrition (HPN) and Home Enteral Nutrition (HEN), either via tube or mouth, in Italy in 2016. Materials and methods: a specific form was sent to all registered SIGENP members and investigators of local HAN centres, inviting them to provide the requested centre's data and demographics, underlying diseases and HAN characteristics of the patients. Results: we recorded 3403 Italian patients on HAN aged 0 to 19 years from 22 centres: 2277 HEN, 950 Oral Nutritional Supplements (ONS) and 179 HPN programs. The prevalence of HEN (205 pts/million inhabitants) and HPN (16 pts/million inhabitants) has dramatically increased in Italy in the last 9 years. Neurodisabling conditions were the first indication for HEN by tube or mouth while HPN is mainly requested in digestive disorders. Conclusions: HAN is a widespread and rapidly growing treatment in Italy, as well as in other European countries. Awareness of its extent and characteristics helps improving HAN service and patients' quality of life

Seeking Signs of Life on Mars: the Importance of Sedimentary Suites as Part of a Mars Sample Return Campaign

Seeking the signs of life on Mars is often considered the "first among equal" objectives for any potential Mars Sample Return (MSR) campaign. Among the geological settings considered to have the greatest potential for recording evidence of ancient life or its pre-biotic chemistry on Mars are lacustrine (and marine, if ever present) sedimentary depositional environments. This potential, and the possibility of returning samples that could meaningfully address this objective, have been greatly enhanced by investigations of an ancient redox stratified lake system in Gale crater by the Curiosity rover

Seeking Signs of Life on Mars: A Strategy for Selecting and Analyzing Returned Samples from Hydrothermal Deposits

Highly promising locales for biosignature prospecting on Mars are ancient hydrothermal deposits, formed by the interaction of surface water with heat from volcanism or impacts. On Earth, they occur throughout the geological record (to at least approx. 3.5 Ga), preserving robust mineralogical, textural and compositional evidence of thermophilic microbial activity. Hydrothermal systems were likely present early in Mars' history, including at two of the three finalist candidate landing sites for M2020, Columbia Hills and NE Syrtis Major. Hydrothermal environments on Earth's surface are varied, constituting subaerial hot spring aprons, mounds and fumaroles; shallow to deep-sea hydrothermal vents (black and white smokers); and vent mounds and hot-spring discharges in lacustrine and fluvial settings. Biological information can be preserved by rapid, spring-sourced mineral precipitation, but also could be altered or destroyed by postdepositional events. Thus, field observations need to be followed by detailed laboratory analysis to verify potential biosignatures. See Attachmen
