Study of soil cover is particularly important for solving the occurred problems from implementation of infrastructure works of the roads. The soil cover is at the upper part of the Earth's crust and has distinct properties morphological, mineralogical, physical and chemical differences due to climate, relief, waters. The interrelatedness of the various geomorphological, climatic, hydrological and soil factors and the human factor, resulted in a wide variety of soils with specific and constantly evolving. In Timi? ...

The objective of the paper was to emphasize the influence of the biological activity on the structural improvement of the compacted clayey pedogenetic horizons of two Chromic Luvisols, by the organic matter bioturbation. The researches were performed on two Chromic Luvisols from Romanian Plain, where the mean annual temperature is 10.5oC and the mean annual precipitation is 548 mm. The analytical data showed that clay content increased from the top layer of both soil profiles (28.9% in P1, and 29.8% in P2), to Bt ...

Evolution and development of landslides is influenced by a number of natural factors (soil, geological substrate, relief, climate, vegetation etc.) and anthropogenic factors (deforestation, overloading of land with constructions, inadequate meteoric waters drain, artificial undermining of slopes-embankments for roads etc.). In this paper we propose to analyze the causes of landslides that affected the county road DJ 585 located in Visag area, Caras-Severin county limit, and also to issuing technical solutions for ...

This article discusses the possibilities of using a 3D printer with parallel kinematics that can produce good quality prototype components such as various covers, handles and functional assembly for simple electronic devices or robots. It will enable combining the printer with an engraving CNC machine, so that the effector head of the 3D printer will allow the head to be exchanged for printing with an engraver head, and it will allow fine engraving on printed circuit boards. The printer effector is equipped with a...
