Factors influencing the choice of the pole pitch of linear inductors of electrodynamic separators

Features of the choice of pole pitch of linear induction machines of electrodynamic separators are considered. As criteria for this choice, indicators are used: operability, energy efficiency, selectivity of separation

Prospects of induction sorting of automotive SCRAP

Recovery and recycling of metals from wastes have a major role in the economy because of the scarcity of raw materials and the problem of environmental pollution. In this article the necessity of using electrodynamics (eddy current) separators for extraction of non-ferrous metals from crushed automotive scrap and sorting of non-ferrous metals by types and grades of alloys is shown. The results of studies of an experimental separator based on a three-phase linear inductor are presented

Infiornativity lacrimal fluid interleukins in diagnostics and development of angle-closure glaucoma in elderly subjects

An increased percentage of the elderly subjects in pattern of contemporary society, along with other causes and risk factors, is accompanied by rise in the incidence of glaucoma. By 2020, according to international studies it is expected that prevalence of glaucoma patients in the world would increase up to 80 million subjects. Among the elderly, glaucoma is a common pathology, which development is associated with local disturbances in interleukin profile. However, the features of the latter in patients with primary closed-angle glaucoma in the elderly were poorly examined. Studies of local interleukin status were conducted mainly in patients with suspected or initial manifestations of primary open-angle glaucoma. The features of lacrimal fluid interleukin shift in a target group of elderly patients suffering from stage II primary closed-angle glaucoma virtually gained no attention. In addition, a limited range of local interleukins in patients with such pathology in previous studies was examined. In addition, informativity of lacrimal fluid interleukins in elderly glaucoma patients was not assessed too based on objective methods. The aim of the current study was to outline features and informativity of local interleukin profile indicators in 58 elderly patients with primary closed-angle glaucoma stage II, aged 60—74 years (main group) and 27 age-matched elderly subjects lacking such pathology. The level of interleukins in the lacrimal fluid was determined with the enzyme immunoassay “Multiscan” analyzer (Finland) by using sandwich ELISA (R&D Diagnostic Inc., USA). Informativity of measuring various interleukins was calculated according to the generally accepted formula. It was found that local interleukin profile in elderly patients with primary closed-angle glaucoma was mainly featured with increased amount of IL-2, IL-17, IL-8, but decreased IL-10. Hence, such local interleukins displayed peak informativity. The data obtained should be used in the diagnostics and treatment of such pathology, as well as of applied importance to unveil novel mechanisms behind development, diagnostics and corroboration for selective immuno-tropic therapy of primary closed-angle glaucoma

INCREASING THE EFFICIENCY OF EDDY-CURRENT SEPARATION OF SOLID WASTE IN A TRAVELING MAGNETIC FIELD

The paper shows the use of eddy-current separators for the extraction of metals from a solid waste stream. To reduce the power consumed by the separator from the network, it is proposed to use a modular design of the separator inductor. Shown is a comparison of the trajectories of metal particles in the basic version of the separator and when using a modular design of inductors.В работе показано применение электродинамических сепараторов для извлечения металлов из потока твердых отходов. Для снижения мощности, потребляемой сепаратором из сети, предложено использовать модульную конструкцию индуктора сепаратора. Показано сравнение траекторий движения частиц металла в базовом варианте сепаратора и при использовании индукторов модульной конструкции
