چکیده
The article addresses the problem of functional purpose shaft-type furnaces with chimneys found at Late Bronze Age sites Northern Eurasia. This category thermal engineering structures became widespread in eastern wing West Asian (Eurasian) metallurgical province. Thermal sets flue channels are physical evidence implementation technological algorithms pastoral model metal production based primarily on multistage processing secondary copper sulfides. Shaft flues Ural-Kazakhstan region functionally similar to more structurally simple fi re pits-furnaces present structure mining and complexes steppe Cis-Ural region. They were intended for decrepitation, pyrotechnic enrichment, refining ore protolith during a long setting using brushwood wood fuel relatively low temperatures range 600–800 °C. degree complexity was determined by nature raw materials used. Ordinary pits turned out be acceptable ore-bearing shales sandstones ores ultrabasic deposits Ural-Mugodzhar difficult processed required use mine flues, which also characteristic centers Kazakhstan Further improvement due need overcome material crisis caused exhaustion available sulfide reserves enrichment zones within deposits, shale occurrences end Age. It transition chalcopyrite greatly contributed discovery iron metallurgy.

عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
