Dry Magnetic Separation of Iron Ore of the Bakchar Deposit

Currently, the development of iron ore of the Bakchar deposit (Tomsk region) is considered promising because of the extremely large reserves of iron ore. Ores of this deposit are related to the high-grade type and expected to have a magnetic concentration for iron extraction. The main task of magnetic separation is to increase the total iron content in concentrates to a value which allows its further metallurgical processing. Ferruginous ore particles have a rounded shape that facilitates a separation process. The paper considers the influence of technological parameters on the magnetic concentrate yield and recovery rate of iron-containing fractions

The Influence of Ageing Process on the Barium Aluminate Phase Composition

Barium aluminates were formed by the continuous precipitation method at different values of pH. The influence of ageing process and precipitation pH on the phase composition of the precipitate after firing was found. It was showed that there is growth of the 3BaOAl[2]O[3] concentration after ageing of precipitate during 7 days. Presumably, this process is associated with a decrease in the number of crystals, increasing their size in the ageing process of precipitate and chemical processes that occur during ageing: hydrolysis, hydration, dehydration

Hydronephrosis in the neonatal period of children

In this article we carried the research full-term and preterm newborn infants with diagnosis hydronephrosis born in the period from 2015 to 2018 under observation in clinic ODKB, Ekaterinburg. We took into consideration the evaluation such criteria as sex, period of antenatal diagnosis and delivery, term of admission to the hospital, type of drainage in pyeloplasty, complications.В данной статье проведено исследование доношенных и недоношенных новорожденных детей с диагнозом гидронефроз, рожденных в период с 2015 по 2018 годы, находившихся на лечении в ОДКБ г.Екатеринбург. Оценке подвергались: пол, срок антенатальной диагностики и родоразрешения, сроки поступления в стационар для проведения обследования, вид дренирования при пиелопластике, а также наличие осложнений

On-line vibrodiagnostics of technological pipelines and gas-pumping equipment of compressor stations

The paper was aimed at the development and introduction of new methods and technical means of the on-line vibrodiagnostics of the pipelines and gas-pumping equipment of compressor stations. As a result the problem of recognition of a set of defective states was solved on the basis of the regularities of mutual distribution of vibrospeed levels of the vibration signal spectrum. The results obtained have been introduced into operationAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio

Etiology and Pathogenesis of Sudden Cardiac Death

BACKGROUND AND DEFINITION: This article contributes to the current state of knowledge in etiology and pathogenesis of sudden cardiac death (SCD). SCD is a well - defined disease entity which recently approved international guidelines address (cardiac death within 1 hour). ETIOLOGY: The condition of coronary arteries contributes to common causes of SCD. Stenotic coronary artery sclerosis (80%) has been reported in most cases. In non-coronary causes (15%), cardiomyopathies (CMP) are frequently found, and alcoholic CMP dominates the CMP cohort. Genetically related causes are comparatively rare (5%). PATHOGENESIS: In pathogenesis, only the consecutives of coronary ischemia have been extensively studied, in contrast to non-coronary causes. Herein, only some (mostly infectious) forms of myocarditis have been investigated in detail. The pathogenesis of different causes of SCD is less well studied. These include pathologic changes of adrenergic and cholinergic heart nerves, of intra- and extra-cardiac ganglia and of the conduction system. Morphological changes that clearly explain SCD are still difficult to reproducibly detect in clinical-pathologic and forensic autopsy diagnosis because these lesions might morphologically at first manifest after 1 hour or even later. This statement holds particularly true for detecting early ischemic heart muscle cell deaths being the most common cause of SCD. CONCLUSIONS: The reported methods and special staining have proven to be less suitable for routine diagnostics. Attempts are now undergoing to solve the problem by the use of specific antibodies. They provide evidence of immunoreactivity of ischemic damaged cardiomyocytes which can be detected even after prolonged postmortem lay times
