estimation of the amount of soil loss measurement of field indicators is a low-cost method, is easy to learn and can be simply applied. in order to measure and make assessment of soil loss amount by field indicators method in shahrak watershed, first map of the work units was prepared and then, measurements of the relevant field indicators were carried out within these units. then, epm model wa...

We discuss the hard X-ray properties of the Seyfert galaxy Ton S 180, based upon the analysis of ASCA data. We find the X-ray flux varied by a factor ∼ 2 on a time scale of a few thousand seconds. The source showed significantly higher amplitude of variability in the 0.5–2 keV band than in the 2–10 keV band. The continuum is adequately parameterized as a Γ ∼ 2.5 power-law across the 0.6–10 keV ...

After having analyzed advantages and disadvantages of the possible solutions for the vacuum system for the T600 we estimate in some details the performance a given commercial solution. Pump down times and final vacuum are computed either analytically and with dedicated simulation software. We also estimated the concentration of impurities left in the volume after the cool down and defined some ...

Over the last 15 years, various oncology groups throughout the world have used the PRETEXT system for staging malignant primary liver tumours of childhood. This paper, written by members of the radiology and surgery committees of the International Childhood Liver Tumor Strategy Group (SIOPEL), presents various clarifications and revisions to the original PRETEXT system.

We show that the “ridge” phenomenon in the two-particle angular correlation function, as observed by the CMS experiment, can be reproduced by implementing an impact parameter dependent azimuthal correlation of the scattering planes of individual partonic interactions. Such an approach is motivated by the observation that even for moderate impact parameters a substantial number of partonic inter...

to compare potential of two organic materials including sewage sludge (ss) and municipal solid wastecompost (msw) on micronutrients entry to soil, a research was conducted as split-plot arrangement basedon randomized complete block design with three replications in research field of sari agriculturaluniversity. main-plot (fertilizer treatments) included 20 and 40 ton/ha ss, 20 and 40 ton/ha ss ...

Pre-seeding tillage of long-term no-till soil may alter soil quality by changing some properties, but the magnitude of change depends on soil type and climatic conditions. Effects of short-term (2 or 3 years) tillage (hereafter called reverse tillage [RT]) of land previously under long-term no-till (NT, 29 or 30 years), with straw management (straw removed [SRem] and straw retained [SRet]) and ...
