Based on the principles of prevention, the employer must seek to eliminate risk at source and, in order of priority, to replace hazards through non-dangers, to separate or isolate areas where there are hazards, ensuring adequate collective and individual protection. However, workers from high and very high voltage power substations continue to be exposed to occupational hazards, suffering accidents at work and occupational diseases with significant repercussions on their health, on colleagues or National Power Sys...

The SWOT analysis of the energy resources of hydrocarbons comes in the context in which the possibility of a black-out is very likely, and the lack of energy resources can cause major damage through enormous financial losses, which through the domino effect can spread economic and national insecurity. In this context, the SWOT analysis energy resources become an essential issue of national security and makes this paper of real interest. The authors consider that the security supply with energy resources of hydroca...

In special applications it is necessary to correlate the obtained data about the state of a process in which the Joule effect is involved by passing an electric current through a conductive material. The multiplier effect due to increased resistance with temperature may require particular attention in monitoring the process, thus requiring automatic decision-making processes so that the modification of the conductive material properties does not affect the entire chain of the process. We propose a system for monit...

This paper is a sequence that is part of the extensive analysis of the Danube Delta genesis. Sacalin island is a territory formed in the Black Sea, a short distance from the Romanian coast, in the south of the Saint Gheorghe branch of the Danube Delta, the main source of transport for alluviums. The history of this new territory is relatively recent. The first mention was in 1771. In 1856, Captain Thomas Spratt made a new map, in which the island of Sacalin appeared with two submerged nuclei. In 1924, Romanian res...

The Danube Delta dynamics formation and expansion represent the motivation of the study included in this paper. The results of soil studies made possible to develop the Danube Delta genesis maps [7]. That informationпїЅs are the input data and the validation data for the numerical flow studies of the Danube River. The study of the formation of new territories has been developed by the Computational Fluid Dynamics (C.F.D.) method. There were modelled in three dimensions the maps for Danube River Basin flowing into ...

The purpose of this study was to identify the factors of influence in alluvial deposits due to the anchoring of barges in the vicinity of river ports. The problem of analysis was identified at the anchorage of the barges near the Galati Mineral Harbor on the Danube River. The area of the navigable channel located downstream of the mineral port is affected by alluvial deposits. Major problems occur in the summer months, when Danube waters are very low. Analysis of these issues was done with the SolidWorks Flow modu...
