متن کاملTemperature Dependent ESR Studies on
Frozen samples of aqueous solutions of oxidized Pt 6-methyl-uracil "blue" were studied bv ESR spectroscopy at temperatures T ranging between —196 °C and —10 °C. When T was raised a distinct change in the line pattern was observed at about —35 °C. The resulting type of spectrum is very similar to the ESR spectrum of MAGNUS' Green Salt. The observed effect is suggested to be due to a change of th...
متن کاملEffects of Soil Temperature and Moisture on Soil Respiration on the Tibetan Plateau
Understanding of effects of soil temperature and soil moisture on soil respiration (Rs) under future warming is critical to reduce uncertainty in predictions of feedbacks to atmospheric CO2 concentrations from grassland soil carbon. Intact cores with roots taken from a full factorial, 5-year alpine meadow warming and grazing experiment in the field were incubated at three different temperatures...

متن کاملRadium and radon exhalation studies of soil
Background: Everyone is exposed to radon because it is present everywhere with varying concentrations. Radon and its progeny are well established as lung carcinogenic. Materials and Methods: Track etch technique using LR-115 plastic track detectors has been used to measure the effective radium content and radon exhalation rates in soil samples collected from urban area of Etah district...
