This study refers to the methodological framework for performing the cost-benefit analysis, at the level of a river basin, for the program of measures needed to achieve the good environmental condition of water bodies within the framework of Water Framework Directive (WFD). The Cost-Benefit...

In the paper, considerations on the destruction process of the stratospheric ozone by substances emitted by anthropogenic pollution sources and which reach in the stratosphere by transport from the troposphere are presented. In the stratosphere, the lifetime of these substances is less than in...

In the Eulerian approach the behavior of the atmospheric pollutants is described relative to a fixed coordinate system. Thus the pollutant concentration is a function depending on the system coordinates and must satisfy the material balance taken over a volume element. Expressed mathematically,...

The present study wishes to bring to the attention of the reader the alarming impact that the common benzene molecule has on the environment, with unimaginable implications on the human being. Although it has a great economic importance, being used in many industries, specialists are underlining...

Protecţia mediului a devenit o preocupare majoră afişată de majoritatea agenţilor economici în comportamentul lor social, politic şi din ce în ce mai mult în cel economic. Fără îndoială, acest interes colectiv are la bază ideea că resursele mediului nu sunt mereu exploatate corect...

The deterioration of the environment is caused by the existence of large urban agglomeration whose main problem is that these are areas where are converging progressive forces which ensure the development of the society on the one hand, as well phenomenon which emphasizes the degradation of the...

Romanian Abstract: În contextul actualei crize economice, reducerea costurilor are o importanţă deosebită în orice domeniu de activitate. Totodată, conformarea cu cerinţele de mediu reprezintă de asemenea un factor esenţial. Datorită acestor aspecte, analiza eco-economică,...

The exergetic model is superior to other methods of study of mining pneumatic networks thermal processes. It allows us to find out the energy losses and exergetic efficiency. Thus, we have more opportunities for increasing these installation performances

Most interesting appearance in under consideration exergetic concerning the helical screw compressor represents it the possibility identified the weakly point from the cycle of operation. The identification and then improvement weakly points will permit the utilization energies in superior...

In the present study explored the effects were obtained for two passive measures: improved thermal insulation and general tightness of the building. Were quantified comparative energy performance for building real reference building, energy efficient building and rehabilitation variants I and II.
