Газочувствительная композиция оксида вольфрама с многостенными углеродными нанотрубками

Multiwall carbon nanotubes (MWCNTs), exhibiting high gas adsorption activity, have been prepared in the high voltage discharge plasma under atmospheric pressure from a mixture of hydrocarbons (methane, propane) and air. The structural characteristics of nanotubes have been studied by TEM. Composition WO3 - MWNTs, prepared by sol-gel method, is of interest to create selective sensitive detectors of combustible gases. The greatest sensitivity to propane (≤ 500 %) has been observed at the substrate temperature below 200 °C, whereas high sensitivity to NO2 (≤300 %) has been observed at higher temperatures (T - 240 °C and more).Получена газочувствительная композиция оксида вольфрама с многостенными углеродными нанотрубками (WO3 - МУНТ), представляющая интерес для создания селективных чувствительных датчиков горючих газов. Изготовлены и испытаны микромощные сенсоры (P ≤ 85 мВт), содержащие WO3 - МУНТ в качестве чувствительного элемента. Наибольшая чувствительность к пропану ( ≤ 500 %) наблюдается при температуре подложки менее 200 ˚С, в то время как заметная чувствительность к NO2 ( ≤ 300 %) наблюдается при более высоких температурах (T ≈ 240 ˚С и выше)

МОДЕЛЬ ПРОЦЕССА БЫСТРОГО ПИРОЛИЗА МЕЛКОДИСПЕРСНЫХ ФРАКЦИЙ РАСТИТЕЛЬНОГО СЫРЬЯ

The mathematical model of the fast pyrolysis of wood particles is presented. The implicit finite difference algorithm for solving the obtained heat and mass transfer equations is constructed. Based on the computational experiments it was found that the fast pyrolysis of pine sawdust entering a heated reactor is possible when the size of their particles does not exceed 0.45 mm, humidity – 10–15 wt. % and at a pyrolysis temperature of above 490 °C.Предложена физико-математическая модель процесса быстрого пиролиза сосновых опилок. Построены неявные конечноразностные вычислительные алгоритмы для решения систем уравнений математической модели. На основании вычислительных экспериментов установлено, что быстрый пиролиз сосновых опилок, поступающих в разогретый реактор, возможен при размере их частиц, не превышающем 0,45 мм, влажности 10−15 мас. % и при температуре пиролиза выше 490 °С

Assessment of needs in orthopedic treatment of patients of an older age group

PREVENTION OF CARDIOVASCULAR COMPLICATIONS IN DIABETES MELLITUS: THE ROLE OF ASPIRIN

The review presents modern national and international evidence on aspirin therapy in patients with diabetes mellitus. The results of multi-centre studies which investigated aspirin effects on cardiovascular complication risk among diabetic patients are analysed. The modern guidelines on aspirin therapy in diabetes mellitus are discussed

Paramyxoviral zoonoses associated with Chiroptera

The paper describes natural historic aspects of emerging dangerous paromyxoviral infections associated with chiropteran reservoir species - Hedra, Nepah, Menangle viruses, their origin and spread

Vulvovaginal infections in the postantibiotic era. How to avoid aggression?

High incidence of recurring aerobic/nonspecific vaginitis is associated with the formation of stable pathological biofilm. The increasing antibiotic resistance does not allow to eliminate associations of conditionally pathogenic microorganisms and inhibits the growth of lactobacilli. Vaginal use of bacteriophages is a targeted antibiotic therapy. The study showed that multivalent bacteriophage (Sextaphage®) used as vaginal monotherapy is comparable with antibiotic in terms of treatment efficacy of aerobic vaginitis, does not reduce the level of lactobacilli and has a high compliance

Imitators of severe preeclampsia: on differential diagnosis and multidisciplinary management

Preeclampsia (PE) is not only a disease of pregnant women, but also a disease with lifelong consequences for mother and child. Making an early diagnosis and differential diagnosis of PE is crucial yet challenging, since PE can be mistaken for other internal diseases or surgical conditions. Despite the variety of clinical symptoms of thrombotic microangiopathy that may manifest in a non-typical picture of PE, progressive multiple organ failure develops in all cases. It seems promising to study the role of matrix metalloproteinases and determine the genetic predisposition to early and severe PE. The forecast and prevention attempts must begin from the fertile cycle. A better knowledge of biochemical and genetic markers along with the clinical and instrumental tests will reduce the morbidity and mortality in PE patients
