Soil, the one of the main components of the environment, is constantly subjected to the action of pollutants existing both in air and water from rainfall and also in groundwater. Soil pollution recorded in the current stage varying degrees of contamination in relation to the demands manifested, chemical contamination occupying a preferential place being pronounced across the globe, regardless of zone. In view of the above purposes, the paper aims to highlight the impact of industrial processing of oil activity on soil quality, near a chemical plant in Constanta County.

Rainfall is a major component of the environment and the main source of the air purification becouse of many pollutants increases who have the most varied sources: various human activities including industry and agriculture, and some household duties. Air purification by means of precipitation is achieved by numerous highly complex mechanisms. The final products of degradation of the pollutant in the air, which are generally harmless, can be reacted with each other in the presence of water, giving rise to the final compounds with a high toxicity. Thus, exhaust, mobile sources of noxious almost identical to those specific activities in the industrial processing of oil, contain lead which is the ideal catalyst for converting SO2 to sulfuric acid in the presence of rainwater, with all the disadvantages that they create. This paper will present an experimental research oabout how rainfall water quality is influenced by the activity of the industrial processing of oil, in a chemical plant in Constanta County.

Protecting the environment is a matter of great importance that must be treaty very seriously, both internationally as well as nationally.The actual situation in Romania, about the economy and the state of the environment, requires the development of a program corresponding to its own interests. Given the specific situation of Romania, the transition to a strong market economy, the restructuring of the economy, the stages that we will go through this market strategy, will mark certain phases with clear objectives.The paper will present the objectives of environmental protection strategy's, industrial risk analysis that affect environmental quality, environmental impact assessment methods and problems of ecological marking of the products. Based on strategies can be developed economic and environmental programs, which must be completed in order to achieve the set objectives, either macroeconomic, sectorial, regional, operative coordination (mandatory) or programs of measures at the firm level, and, why not, national plans.

Abstract:There are many welded structures in the world such as bridges and viaducts that are subject to fatigue. These structures, generally made of non-alloy or low-alloy steels, have been put into operation some of them with many years ago and have accumulated a large number of variable load cycles over the time. For this reason the occurrence of fatigue phenomenon is inevitable and consists in the occurrence of failures at stresses applied to the structure, below the yield limit of the material. These stresses under the static loads would not cause the failures to appear..This paper will investigate whether two reconditioning techniques "weld toe grinding" and "WIG remelting weld toe", influences favorably the behavior of welded structures made from HSLA steel, in static and variable loads and therefore if the application of these techniques is justified in both cases. In the paper will be presented the chemical composition and mechanical properties of the base and filler materials, micro and macrostructures, graphics with the variation of microhardness, static and fatigue tensile tests will be performed, and it will be rised durability curve in case of fatigue tests.

The aim of the present paper is to study the Galvanic Skin Response (GSR) level on subjects affected by stress. The device that we have used, connects to the people by finger electrodes to record GSR. The purpose was to find statistical differences between the activities (mental task, walking, sitting and to fill out a survey about their lives) and their stress level. During the experiment, it was found that the survey caused the source of high stress and increasing skin conductance was caused by sweat secretion (mental, physical activity). Is needed to work of collecting data from more subjects because GSR is depended on human behaviour, is variable upon many factors (their eating habits, their emotional state, their gender, their relationship with family, etc) and we need to build a substantial data set for a valid research.
