The occurrence of nonconformities in prosthetics or medical instruments as a result of the manufacturing process or final machining (finishing) may lead to the decision of not using them in the medical process. The present paper aims to analyze the welding reconditioning possibilities in order to ensure the necessary geometrical characteristics, using the method of finite element analysis (FEA), of the interlocking intramedullary nail prosthetics made of titanium or titanium alloys. After identifying the nonconfor...

The paper presents and analyzes the experimental results obtained by the welding reconditioning of a pressure vessel made of 14CrMoV4, a Romanian trade of steel, which is the equivalent of 13CrMo4-5, in the European norm 10028-2/2009, steel, which functioned for a long period of time in the energetic industry. The welding process used for reconditioning is robotized gas metal arc welding (GMAW). A series of samples were realized using different technological parameters in order to obtain different geometrical conf...

Over a period of two years (2015, 2016), in a field experience organized on a Chernozems in south-eastern part of Romania, it was investigated the effect of soil fertilization with compost made from three organic waste (farmyard manure, sewage sludge, and marine algae), in different variants resulting from the mixtures of the three components in different proportions, 50% each and 25% the other two, applied to soil in doses of 25, 50, 75 and 100 t/ha. It is important to note that these compost doses were been admi...

Due to the global problem of desertification, the demand in the diagnostics of the soil forming in the desert conditions is increased. The desert varnish and the vesicular (porous) crust horizon are distinctive morphological features of desert landscapes and, at the same time, generally recognized features of desert soil formation, being commonly referred to as the yermic horizons in different sub-groups within reference groups of desert soils. The objects of the present study were the surface horizons of vesicula...
