HISTORY AND STATUS OF MOOSE IN THE ROSTOV REGION, RUSSIA

Moose (Alces alces) disappeared from the Rostov region in the 19th century due to agricultural development, hunting, and deforestation. They reappeared in the second half of the 20th century due to broad conservation measures including intensive forest management, and by the 1970s numbered >1000 and were found throughout the region. Although hunting was regulated, the population became stagnant in the 1980s presumably from trophy hunting that skewed the sex and age structure, as well as measurable wolf (Canis lupus) predation. Political reform in the 1990s further caused population decline due to increased and less regulated hunting, increased poaching without punishment, reduced predator control, decline in forest management, and large forest fires. Currently the population is at a 50-year low and occupies 1/3 of its range in the 1980s. Moose are no longer considered a commercial species, rather a species of concern

Development of Annealing Conditions wire Rod Alloy of Al-Zr System to Reach Required Properties

В статье рассмотрено влияние непрерывного и ступенчатого отжига на удельное электрическое сопротивление и механические свойства катанки из малолегированных сплавов системы Al-Zr для достижения заданного уровня свойств. Установлена связь между концентрацией легирующих элементов, структурой и свойствами катанки из исследуемых сплавов. Разработан и рекомендован для внедрения на предприятиях алюминиевой промышленности ступенчатый режим термической обработки, позволяющий получать катанку с соответствующим уровнем свойств международного стандартаIn this article was considered the influence of continuous and stepped annealing on resistivity and mechanical properties of dilute alloy wire rod of a Al-Zr system for reaching of required properties. There was determined the connection between concentrations of alloying elements, structure and properties of investigated alloys wire rod. The stepped heat treatment conditions was developed and recommended for application at the factories of aluminum industry, that allows producing wire rod with properties of international standard
