Bioindication of organic pollution and seawater quality was carried out for the first time in the western part of the Sea of Azov on the basis of species composition and quantitative characteristics of microphytobenthos. A total of 229 algal samples were collected at 17 sites over the period of 2005-2014 on three different substrates in three areas under study: Sivash Gulf, the Kerch Strait and Cape Kazantip. In total, 200 taxa of algae were found, which belong to six taxonomic divisions with a predominance of diatoms. Among those, 108 taxa are indicators of substrate, water temperature, salinity, water pH, trophic state, the type of nutrition and organic pollution of water. It has been shown that the most active self-purification of water takes place in communities on stony substrates. The largest number of algae species (50%) occurs in the cleanest waters of the Kazantip Nature Reserve (Water Quality Classes I–II). The species composition of organic pollution indicators in Sivash Gulf corresponds to waters of Classes III–IV, which are more polluted than those of the Kerch Strait and Cape Kazantip. All the studied areas of the Sea of Azov are cleaner compared to some waters of the Eastern Mediterranean and the Sea of Japan.
The results of treatment of 337 patients, aged from 15 to 75 years, with femur (175 patients), shin (41), arm (76) and forearm (45) fractures were analyzed. Open injuries were present in 42 (12,5%) and closed ones in 295 (87,5%) patients. According to AO classification type A fractures were diagnosed in 146 (43,3%), type В - in 103 (30,6%), type С - in 88 (26,1%) patients. In all patients osteosynthesis with plates and fixing screws was performed. In 37(11%) patients destruction of the implant took place. The dependence of that complication on the pattern of injury and type of fracture is detected: in open and comminuted fractures the rate of implant destruction was reliably higher. Mechanical destruction of the internal fixation system was presented by two variants: either break of a plate in the zone of the most intensive stress and a screw, or bone destruction in the site of screw insertion. In all cases of implant destruction the nonunion of fractures due to devitalization or absence of intermediate fragments was observed.
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.
