INTERNAL AND INTERNATIONAL CONCERNS OVER SUSTAINABLE DEVELOPMENT AND ENVIRONMENTAL ACCOUNTING
Journal Title: TEHNOMUS - Year 2012, Vol 19, Issue 1
Abstract
Sustainable development is the kind of development aimed at meeting the needs of the present, without compromising the ability of future generations to meet their own needs. The European Union has transformed the joint economy - environment into one of its “quasiconstitutional” tasks. Regarding Romania, whose future is tied to the European Union, it is out of the question to have a policy with no clear orientation towards environmental protection.

CONSIDERATIONS REGARDING THE USE OF CHUCK COLLETS IN MECHANICAL SYSTEMS
In this paper the authors aim to present the theoretical study of of constructions such as clenching mechanisms with chuck collets. For this to has been modernized the test stand clenching mechanisms with chuck collets e...
OPTIMAL PERTURBATION FOR MIXED CONVECTION HEAT TRANSFER IN RECTANGULAR CHANNEL
We studied the growth velocity perturbation at the entrance of a rectangular channel for mixed convection heat transfer. The flow is bidimensionnel and the fluid is newtonian, incompressible obeying to Boussinesq approxi...

The paper submitted for publication is a comparative study of the hardness values recorded on metallic and non-metallic samples, values that been taken over with a standardized hardness tester Shimadzu HMV-2T, respective...
A NEW APPROACH OF THE MAIN LANDING GEAR EQUATIONS
In this paper an approach for modeling landing gear systems is presented. Specifically, a nonlinear model of an main landing gear is developed. This model includes nonlinear effects such as a polytropic gas law, velocity...
STUDY OF THE INFLUENCE SOME TECHNOLOGICAL FACTORS ON JOINING RADIUS BETWEEN TWO CONSECUTIV SIDES TO THE ELECTROHYDRAULIC PERFORATION OF THE POLYGONAL HOLES
The paper deals with the influence of technological factors such as discharge energy, angle between sides and thickness of the semi-finished products, on joining radius that obtained to the electro hydraulic perforation...
