Modeling and experimental observations of radio wave propagation by reflection from the Es-layer at short radio-lines

© 2014 IEEE. These The effects of focusing and defocusing at radiowave propagation through the Es-layer are frequently obtained. The large-scale cloud structure of Es layer was used to explain the effects of radiowaves focusing and defocusing by VS[1], as well as estimation of energy loss at oblique propagation[2]. Note, however, that this model can be used with a threshold level of registration not less than -35-40dB, because at lower levels the signal can be obtained by reflecting from electron density gradient and by scattering from the small-scale irregularities of the layer

Childhood intussusception in Uzbekistan: Analysis of retrospective surveillance data

<p>Abstract</p> <p>Background</p> <p>Estimates of baseline incidence of childhood intussusception could help safety monitoring after the introduction of rotavirus vaccines. We studied the incidence of intussusception in Uzbekistan, a GAVI-fund eligible state in Central Asia.</p> <p>Methods</p> <p>We retrospectively reviewed intussusception cases in children <2 years of age treated during 2004-2008 at 15 hospitals in the Bukhara region of Uzbekistan. Demographic and clinical data as well as information on diagnostic and treatment practices were obtained from hospital records. We categorized cases using the Brighton collaboration clinical case definition and calculated the national incidence rate.</p> <p>Results</p> <p>Over a 5-year study period, 67 confirmed cases were identified, of which 67% were boys. The median age was 12 months, and no seasonal trend in the distribution of cases was observed. The diagnostic methods used included abdominal radiography (87%) and ultrasonography (57%). Intussusception reduction by air enema was successful in 33 (49%) patients and 34 (50%) cases underwent surgery. A total of 4 deaths occurred, including 3 deaths in infants aged 0-6 months. The median length of hospital stay was 7.3 (range 0-37) days. The incidence of intussusception is estimated at 23 (95% CI 13.6-32.4) cases per 100,000 child-years, corresponding to approximately 237 cases annually.</p> <p>Conclusions</p> <p>This is the first study to estimate the incidence of childhood intussusception prior to the introduction of the rotavirus vaccination in Uzbekistan. A prospective surveillance system using a standardized case definition is needed in order to better examine the occurrence of intussusception in developing countries.</p

Трансплантация легких при первичной легочной артериальной гипертензии: особенности периоперационного периода

Lung transplantation (LT) for idiopathic pulmonary arterial hypertension (IPAH) now is the only radical treatment of this disease.Aim: to analyze own experience of performing LT in patients with IPAH.Materials and methods. 8 adult IPAH patients, who underwent LT between 2014 and october 2018, were included. In 7 of 8 patients undergoing bilateral lung transplantation on intraoperative venoarterial extracorporeal membrane oxygenation (VA ECMO) with prolongation into the postoperative period.Results. VA ECMO support was prolonged into postoperative period 6 and 7 days respectively in 2 (25,0%) patients and 3 days in 6 (75,0%) patients. Hospital mortality in IPAH patients was 1.Conclusions. Own experience demonstrates that LT is an effective method of treatment in patients with IPAH. Hospital, 1- and 3-year survival rates for the patient collective were 87.5, 75.0 and 75.0% respectively.Первичная легочная артериальная гипертензия (ПЛАГ) – необратимое заболевание, единственным методом радикального лечения которого является трансплантация легких (ТЛ).Цель исследования: анализ собственного опыта выполнения ТЛ у пациентов с ПЛАГ.Материалы и методы. В исследование включили 8 взрослых реципиентов, которым была выполнена ТЛ в период с 2014-го по октябрь 2018 г. Всем реципиентам была выполнена двусторонняя последовательная трансплантация легких. У 7 из 8 реципиентов ТЛ осуществляли в условиях периферической ВА ЭКМО.Результаты. В послеоперационном периоде первичная дисфункция 3-й степени по классификации ISHLT развилась у 2 (25,0%) из 8 реципиентов, которая проявилась невозможностью прекращения ВА ЭКМО. Общая продолжительность применения ЭКМО у этих пациентов (n = 2) составила 6 и 7 суток. У других 6 (75,0%) реципиентов проявления ранней дисфункции пересаженных легких не носили столь напряженного характера (2-я степень по классификации ISHLT), и продолжительность послеоперационной ВА ЭКМО составила 3 суток. Госпитальная летальность у реципиентов легких, оперированных по поводу ЛАГ, составила 1 наблюдение.Заключение. Собственный опыт демонстрирует, что ТЛ является эффективной лечебной мерой у пациентов с ПЛАГ с показателями госпитальной, 1- и 3-летней выживаемости соответственно 87,5; 75,0 и 75,0%

Assessment of the impact of unmanned aerial vehicles with different engine types on the MMPOS-1 magnetometer

© 2020 International Multidisciplinary Scientific Geoconference. All rights reserved. Active development of unmanned aerial vehicles has led to their widespread use for various purposes, and magnetic prospecting is no exception. UAVs in various modifications are used in aeromagnetic surveys intended for magnetic mapping of the subsurface. This allows to solve the problems of not only aeromagnetic prospecting (identification of ore deposits, petroleum prospecting, etc.), but also of geological engineering and archeology. The advantage of using UAV lies in the cheapness and safety of the survey. Magnetic prospecting in this case is carried out with minimal financial and time costs, while the study area is limited only by the time of flight. As a rule, UAV flight time varies from 1 to 1.5 hours. This problem is due to the limitation of the energy source of the UAV. In addition, most UAVs are made from light materials such as carbon composite and aluminum, which has a positive effect on their use in aeromagnetic prospecting. However, there is little research on the impact of UAVs on magnetometers. Most of the work is devoted directly to the processing and interpretation of the results. This paper analyzes the influence of a quadcopter, an octocopter and a two-stroke combustion engine on the readings of the quantum magnetometer MMPOS-1. The impact of electric motors and a combustion engine is shown. A comparative analysis was carried out aimed at revealing the most optimal distance for a magnetometer sensor. The impact of various types of UAV is estimated, depending on their design features
