Mining in upper Me\vza valley had more than 350 years of tradition. Lead and zinc ore deposit was developed in the triassic carbonate layers on the area of 64 km2. Until 1994, when the mining process was stopped, miners excavated about 19 million tons of lead and zinc ore and over 1000 km of galleries and pits. A crucial aspect of the Me\vzica mine was the dewatering issue. Me\vzica ore deposit is developed in Triassic carbonate rocks – limestone and dolomite. The area is of rough mountainous relief rising from ...

The average pattern of weather, called climate, usually stays pretty much the same for centuries if it is left to itself. However, the earth is not being left alone. There is now very strong evidence that significant global warming can’t be explained by natural causes alone. Humans are changing the climate by their actions, especially through emissions of greenhouse gases, like carbon dioxide, which artificially warm the atmosphere of the earth. Scientific studies showed that climate change is fact not a myth or...

Close parallels between transpiration and water deficit indicate that in diseased plants water loss is largely determined by leaf water content. The rate of water loss (transpiration) depends on evaporation. Therefore anything that affects the rate of evaporation would also affect the rate of water lost. There was no clear relationship between leaf growth rate and leaf water potential or turgor for either species. It decreases with leaf age and is correlated with the rate of dehydration, but it is independent of t...
