the scientific and technological principles of metallization of products on the basis of wood with use of plasma high-temperature dispersion are developed. For the purpose of prevention of impact of the highest temperatures of a plasma stream on a front surface wood and fibrous board (fibreboard) an intermediate layer was put.
The structure of an intermediate protective layer, the including mix of epoxy resin with refractory filler is developed. Operation of drawing a protective intermediate layer included several specially developed technological stages. For the subsequent metallization such non-ferrous metals as copper and aluminum in the form of a wire are used. Optimum parameters of plasma dusting of metals on a front surface of a fibreboard are determined
The protective and decorative covering on the basis of non-ferrous metals had high aesthetic consumption and performance properties. The covering possessed the increased coefficient of diffusive reflection and high durability of coupling with a matrix. The dependence of influence of thickness of the raised dust metal covering on durability of coupling of a covering with a substrate is established.
The developed technology of metallization of products from wood in comparison with traditional technologies, allows to lower significantly time of metallization and energy consumption and to increase competitiveness of products both on internal, and on external the markets.
The article presents a comparative assessment of the levels of cytokines that regulate the differentiation of various macrophage phenotypes, as well as immunological responses in patients with diabetes. We examined and treated 245 patients who were allocated to two groups. The first group comprised neuropathic patients (comparison subgroup 1A without DFU, n=30 and subgroup 1B with DFU, n=80). The second group included patients with neuroischemic type 2 diabetes (comparison subgroup 2A without DFU, n=35 and subgroup 2B with DFU, n=100). As an indicator of hyperglycemia, the glycated hemoglobin level (HbA1c) was used, which was determined on the DCA 2000 device by the method of latex immunoagglutination inhibition using the “Hemoglobin A1c Reagent kit”. The concentration of cytokines TNF-α, IFN-γ, IL-6, and OPG in blood serum was determined on the first day of hospitalization before surgery using enzyme immunoassay test systems (OOO “Cytokine”, St. Petersburg) in accordance with the manufacturer's instructions. An imbalance of cytokines was revealed, indicating a shift in immunomodulatory responses, aggravation of metabolic and vascular disorders in tissues, accompanied by an inadequate course of the inflammatory and reparative process and the formation of a diabetic foot ulcer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
