Advancements in the development of gamma-ray spectrometers (GRS) have led to small and lightweight that can be used under unmanned aerial vehicles (UAVs). Airborne GRS measurements are determine radionuclide concentrations ground, among which natural occurring radionuclides 40K, 238U, 232Th. For successful applications these sensors, it is important absolute values measured. To extract concentr...

The article considers the problem related to ambiguity of logging results, which is reflected in reduction efficiency certain interpretive methods, and as a consequence oil gas reservoirs omission. In this regard, analysis results gamma logging, spontaneous polarization nuclear magnetic were conducted. received information experimental researches cores, has allowed establishing reasons distorti...

The objective for decommissioning planning, is to obtain a radiological understanding of the involved installation. characterization at this stage could be carried out by means of: (a) neutron activation calculations based on reactor design and flux; (b) dose rate measurements; (c) in-situ gamma spectrometry; (d) sampling determination scaling factors in activated contaminated components.Neutro...

Our previous studies showed that renal proximal tubular cells (RPTC) express Ca(2+)-independent phospholipase A(2)gamma (iPLA(2)gamma) in endoplasmic reticulum (ER) and mitochondria and that iPLA(2)gamma prevents and/or repairs lipid peroxidation induced by oxidative stress. Our present studies determined the importance of iPLA(2)gamma in mitochondrial and cell function using an iPLA(2)gamma-sp...
