Transition to the basis of the concept of lean production as a succession of negative trends at mining enterprises and metallurgical complex of Ukraine (message 1)

Purpose. Analysis of the peculiarities of the transition to the concept of lean production of the enterprises of the mining and smelting complex (MMC) of Ukraine, located on the territory of the Dnipropetrovsk region. Prospects for the implementation of these approaches by 2020. Methodology. The article used the methods of questioning and interviewing at the stage of collecting primary information, as well as the method of comparative analysis to substantiate recommendations on the prospects for implementing the concept of lean production for the period until 2020. When writing the article, methods of questioning and interviewing at the stage of collecting primary information were used, as well as a method of comparative analysis with the purpose of substantiating recommendations regarding the prospects for introducing the concept of lean manufacturing for the period until 2020. Findings. The article analyzes the transition to the principles of the concept of lean production on the example of two enterprises of the MMC of Ukraine, located within the Dnipropetrovsk region. Perspectives of further introduction of the tools of the concept of Lean Production for the period until 2020 are considered. Originality. The importance of practical application of the methods and tools of the theory of the concept of lean production, in particular systems 5 С and submission of proposals, proved the necessity of applying different methods of an audit of production activity. This will optimize costs within the organization and will affect the level of competitiveness of its products. Practical value. Understanding the fact that the company's profit is only an external manifestation of the correct management decision to minimize losses within the company will allow the enterprises of the MMC to progress in general. Keywords: the concept of lean production, losses, mining and metallurgical complex of Ukraine, management, development

Elemental composition of moss and lichen species in eastern Serbia

Instrumental neutron activation analysis is used to determine a content of 47 elements (Na, Mg, Al, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Ni, Co, Cu, Zn, As, Se, Br, Rb, Sr, Zr, Mo, Ag, Cd, Sb, I, Ba, Cs, La, Ce, Nd, Sm, Eu, Gd, Tb, Dy, Tm, Yb, Lu, Hf, Ta, W, Au, Hg, Th, and U) in mosses (Homolothecium sp., Hypnum cupressiforme Hedw., and Brachythecium mildeanum (Schimp.) Schimp.) and lichen (Cladonia fimbriata (L.) Fr.) collected in three locations in Eastern Serbia over years 2006-2010. Concentrations of six elements (Zr, Nd, Gd, Tm, Yb, and Lu) in mosses in Serbia are measured for the first time. For other elements, the obtained concentrations fall within the ranges reported for mosses and lichens in Europe, but no declining trend in concentrations of V, Cd, Cr, Zn, Ni, Fe, and Cu, that has been described in the literature, can be inferred from our results. Factor analysis shows that terrigenous and industrial components are the highest contributing factors to the elemental composition and that the most polluted measurement site is in the vicinity of a copper mining and smelting complex.
