The issues of increasing the energy efficiency city-forming organizations ferrous metallurgy are considered in this paper. Ferrous is characterized by a high concentration organizations, social significance, and intensity. paper studies consumption metallurgy, highlights directions for use resources.

In the present study, using the powder metallurgy route, varying amount of nano-sized Y2O3 particulates and Nicoated carbon nanotubes (Ni-CNTs) were intentionally incorporated into the Sn-3.5Ag-0.7Cu solder to develop two nanocomposite solder systems. The samples were extruded and characterized in terms of their wettability, thermal, microstructural and tensile properties. Characterization resu...

1.1 Manufacturing processes Major industries with exposure to strong inorganic acid mists include those that manufacture phosphate fertilizer, isopropanol (isopropyl alcohol), synthetic ethanol (ethyl alcohol), sulfuric acid, nitric acid, and lead batteries. Exposure also occurs during copper smelting, and pickling and other acid treatment of metals (Suresh, 2009). Minor uses of sulfuric acid i...

B.Gajdzik, Silesian University of Technology, Faculty of Materials Science and Metallurgy,Katowice, Poland On the basis of report analysis which presents situation in metallurgical sector after 2008 the range of changes implemented in management of metallurgical enterprises was characterised. A defi nition approach to crisis management was suggested as the process when the enterprise is managed...

The history of pre-Columbian metallurgy in South America is incomplete because looting of metal artifacts has been pervasive. Here, we reconstruct a millennium of metallurgical activity in southern Bolivia using the stratigraphy of metals associated with smelting (Pb, Sb, Bi, Ag, Sn) from lake sediments deposited near the major silver deposit of Cerro Rico de Potosí. Pronounced metal enrichment...

Grzybowska, Poznan University of Technology, Faculty of Engineering Management, Poznan, Poland The article presents notions connected with resource structure of useful knowledge packages in metallurgical enterprise. Dependence between building competence of employees and using kno...

detail exactly how sparse medical care was in Scotland. Even if it were available, the authors show that the stringency of the Scottish Poor Law may have denied access to it. One of their tables (9.B) "shows how much was actually spent on doctors per head of the population on the poor roll. The Scottish average was £0.0 154, or no more than 3.d per pauper per year in the old money" (p. 217). Th...
