The mining industry in Maramureș area was an important factor of economic and social progress in this zone. The gradual reduction of th mine activity, until its actual shutdown, has caused disturbances in the economic and social field. This type of industry was, and it continue to be, even in inactivity periods, a pollutant factor. Protecting the e...

Copper sulphate is used as an antifungal agent. Long-term applied fungicides allow the accumulation of copper in soil. This metal pollution is a problem when it enters in the food chains. In this study we investigated the effects of CuSO4 x 5H20 at different concentrations (0.05g/L; 0.1g/L; 0.5 g/L; 1 g/L) on seeds germination. The experiments have...

When mobbing has already begun, it may be difficult to keep it under control if immediate action is not taken. Trusted advisers and mediators can play a very important role. To intervene early, the supervisor must be able to read the first signs of mobbing process in development. Top management can be to appoint one or more persons in the organizat...
