The paper presents the results of precise monitoring of the regime of groundwater at the territory of the Geophysical Observatory of IDG RAS "Mikhnevo". Variations of water level in the isolated aquifer depend on regime controlling factors that have episodic and stationary effects on the aquifer. Detecting and studying the reaction of groundwater to stationary lunisolar tides are of special interest. The tidal effect in variations of groundwater level can be considered as a probing signal for diagnostics of stress...

In this study, enhancement and stabilization of photoluminescence (PL) by porous silicon (PS) were investigated. The PS samples were metallized in solutions containing 3 mM NaNO3 metal salt using immersing plating method. The surface bond configuration of PS was monitored by Fourier Transmission Infrared Spectroscopy (FTIR) and it was found that the PS surface was oxidized after the metallization. The PL intensity increased after certain critical immersion times and PL spectrum shifted towards the high energy regi...

The reservoirs created behind dams built on the main interior rivers of Romania as well as on the Danube have increased the country’s available volume of usable water. The reservoirs’ location and the way they were managed resulted in a decrease of the retention capacity, due to large quantities of sediments accumulated in these lakes. The reservoirs on the rivers Bistriţa, Buzău, Ialomiţa, Argeş and Olt have been affected the worst by the silting process. On average, the values range from 0 - 25\% of the ...

Starting from the recently proposed hypothesis [1] on the Moon formation from the ejection of terrestrial mantle material in a heat-propelled jet, triggered by a run-away natural georeactor at Earth’s core-mantle boundary, we estimate the energy losses in the Earth-Moon system, develop dynamics of this process and compare produced value of the heat with known estimations for heat produced by heavy radionuclides fusion in the Earth body. We conclude that the values of heat produced in these two processes are comp...

This paper highlights the fact that environmental issues in the border regions are numerous. These problems in border regions are endemic to many countries. At global scale of the whole planet, the importance of transboundary pollution of the air, water, soil is far from negligible (according to reports submitted to the UN). Almost 50\% of our planet earth (excluding Antarctica) is located in international water collection tanks. In this area about 40\% of world’s population lives, stretching over more than 200 ...

As the water has a vital role in human life and economic development, its shortage can cause some economical, agricultural, industrial and environmental problems. These problems are more prominent in warm and dry regions. Therefore, in such areas the water resources management as well as the treatment and recycling of the mine drainage have the great importance. In the underground and open pit mines, we usually deal with the huge amounts of the contaminated water. In this research, by considering of the statistics...

Hydraulic impact hammers are one of the mechanical excavators that can be economically used in tunneling projects under favorable geologic conditions. However, there is relatively less published material in the literature directed to their performance prediction in terms of rock properties. In tunnel drivage projects, there is often the need for accurate means of performance prediction of related mechanical excavators. A poor prediction of machine performance can lead to very costly contractual claims. In this stu...
