Aerial photographs are used to develop a relationship between the number of debris slides generated during a hydrologic event and the size of the event, and the longterm average debris-slide frequency is calculated from climate records using the relation. For a site in California with an average of 8.3 slides km yr, a sequence of four photo sets (representing 10–15 years, 35–50 observed slides,...
The present study aimed to compare the rate of net nitrogen mineralization as one of the most important biological properties of soil in managed and control forests of Khalilmahle series 1, Behshahr. Net N mineralization was measured using the buried bag method. Four points from each forest were selected for sample preparation. At each point, three samples (samples of A, B, C) were taken at 0...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
Introduction: In radiation therapy, the accuracy of dose calculations by a treatment planning system (TPS) is important to achieve tumor control and to spare normal tissue. Treatment planning system calculations in the heterogeneous situation may present significant inaccuracies. In this study, three different dose calculation algorithms, pencil beam (PB), collapsed cone (CC), ...
This paper describes a clever way of deriving net community production (NCP) using measured mixed layer concentrations of N2O, O2 and CO2. This seems to me to be a basically sound approach and is appropriate for publication in Biogeosciences. In agreement with the exhaustive comments of a previous anonymous reviewer I believe that the major issues to address are those relating to data and calcu...
We attempt to explain the large = p ratios measured in heavy ion collisions at 12 A GeV=c beam momentum within an hadronic framework. The ratios are large compared to corresponding ratios in pp collisions, and to thermal ts. We show using a simple model and a detailed cascade calculation that di erent annihilation cross{sections of 's and p's, and the net conversion of p's to 's, do not accou...
This paper reviews magnetic flux signal calculations through pick-up loops using vector spherical harmonic expansion under the quasi-static approximation, and presents a near-analytical method of evaluating arbitrary parametrizable for each degree. is done by simplifying surface integral (2D) into line (1D). For special case tangential circular sensors, we present fully analytical recursion cal...
We attempt to explain the Λ̄/p̄ ratios measured in heavy ion collisions at 11.6 A · GeV/c beam momentum within a hadronic framework. This ratio is enhanced relative to corresponding ratios in pp collisions, and is large when compared with thermal fits to heavy ion data. Using a detailed cascade calculation, we show that different annihilation cross–sections of Λ̄’s and p̄’s, and the net conversion ...
