In order to evaluate the coal pillar stability in recovery of residual room pillars under different mining rates, this paper studies influence loading rate on mechanical properties body. The uniaxial compression tests samples Yangcheng area at rates were carried out with MTS815 electrohydraulic servo rock mechanics test system. stress-strain curves and evolution characteristics AE signals analy...

Abstract Effects of water stress on root and leaf growth rates and their relationships with yield under normal and water stress conditions were examined at the Greenhouse and Research Field of Faculty of Agriculture, Kerman University, Iran, using seven maize cultivars including SC-404, SC-704, BC-666, TC-647, DC-370, Jeta and Kordona. During a period of 14 days, water stress at -0.4 MPa was ...

In bargaining environments with uncertain impasse outcomes (e.g., litigation or labor strike outcomes), there is an identification problem that confounds data interpretation. In such environments, the minimally acceptable settlement value from a risk-averse (risk-loving) but unbiased bargainer is empirically indistinguishable from what one could get with risk-neutrality and pessimism (optimism)...

Central among the questions explored in biology are those that seek to understand the timing and rates of evolutionary processes. Accurate estimates of species divergence times are vital to understanding historical biogeography, estimating diversification rates, and identifying the causes of variation in rates of molecular evolution. This tutorial will provide a general overview of divergence t...

The effects of unnatural disturbances on the behaviour and energetics of animals are an important issue for conservation and commercial animal production. Biologging enables estimation of the energy costs of these disturbances, but not specifically the effect these costs have on growth; a key outcome measure for animal farming enterprises. We looked at how natural and anthropogenically induced ...

Data transfer is an indispensable step that is widely involved in the maintenance and processing of Cloud data. Due to rapid growth in Cloud data, methods of reducing the huge energy consumption of data transfer in the Cloud have become a challenge. In this paper, we propose a novel energy-efficient data transfer strategy called LRCDT (Link Rate Controlled Data Transfer). By scheduling bandwidt...

to evaluate the effect of reduced doses of foramsulfuron and nitrogen rates on weed biomass in corn field, an experiment was conducted using split plots arrangement based on randomized complete block design with three replications at research field of ferdowsi university of mashhad, in 2011. main plots were weed control levels comprising three reduced herbicide doses of foramsulfuron (50, 75, a...
