SAR Interferometry is a method that allows to measure land subsidence on radar coherent areas with high precision. This method can measure displacements of the terrain surface smaller than one centimeter. A very important feature of the method is that since the SAR data are acquired frequently it is possible to use archived data to measure deformations over the last fifteen years for almost any...

Introduction Water constitute about 60-80% of body weight of a chicken. Underground water in many parts of the country is saline in nature (1). A poor quality of drinking water may result in wet droppings and decreased feed efficiency. Aflatoxins (AF) are the most common contaminants of animal feed and feedstuffs. There are reports describing the interaction of aflatoxins with other substances....

Satellite Radar Interferometry is a unique method that gives us a possibility to take measurements of a land subsidence on strictly determined huge areas and with precision state the time range. This method uses the phase signal difference between two SAR satellite images (Synthetic Aperture Radar). Until this time this method was successfully tested on underground coal mining areas in the Uppe...

A programmed software was developed in order to numerically simulate time variation of temperature field and snow depth around a pipe-in-pile snow-melting system, using meteorological data. The system utilized underground piles as heat exchanger between underground soil and water flowing inside the piles. The water was pumped into heat dissipation pipes embedded beneath pavement surface, on whi...

Background: In this study, the health risk associated with three types of drinking waters (fissure, underground treated and surrounding waters) from two mines in South Africa were assessed. Materials and Methods: The measurement of the radionuclides concentration was carried out by liquid scintillation counter and alpha spectrometer. The estimated radiological risk pose to the people consuming ...
