Effects of prescribed fires on the 1-year establishment of white oak seedlings were investigated on the Clemson Experimental Forest, South Carolina, USA. Three stands, each consisting of a burn and a control treatment of about 1 ha in size, were examined in the study. On each burn and control treatment, six to eight dominant white oak trees were randomly selected along the slope and four 2-m ra...

This short paper explores density evolution (DE) for low-density parity-check (LDPC) codes at signal-to-noise-ratios (SNRs) that are significantly above the decoding threshold. The focus is on the additive white Gaussian noise channel and LDPC codes in which the variable nodes have regular degree. Prior work, using DE, produced results in the error floor region which were asymptotic in the beli...

the production of oxygen radicals in plants under salinity stress conditions in an the important factor for a diminishing of a photosynthesis and a cause fir a decrease in later vegetative growth. in order to study the effects of antioxidants and salinity stress on photosynthetic characteristics and growth in olive, an experiment was conducted in the research greenhouse of tabriz university in ...

In this paper, we provide a novel approach to distinguish livable urban densities from crowded cities and describe how distinction has proved be critical in predicting COVID-19 contagion hotspots low- middle-income country. Urban population density—considered as the ratio of land area, without reference floor space consumption or other measures livability—can have large drawbacks. To address dr...

This experiment was conducted to determine the effects of oyster mushroom on performance and blood biochemical characteristics in Japanese quails (Coturnix Japonica). A total of 240 seven day old mix sexes quail chicks were randomly allocated to four experimental groups. Each treatment consisted of three replicate pens with 20 birds. Experimental groups included 0, 0.5, 1, 2% oyster mushroom in...

abstract         background and objective: scientific evidence reveals that the density of skeletal muscle microcirculations decreases in the patients with chronic heart failure. therefore, this study aimed to determine the impact of submaximal aerobic exercise training on restoration of fast/slow-twitch muscle fibers microcirculation in rats with myocardial infarction.          methods: in thi...

The Kordkanlo Basin, one of the Atrak sub-basins, located in the northeastern of the Ghoochan city, the Khorasan Razavi Province; is situated in Kopet Dagh geologic zone. The overall objective of this study is to evaluate the morphotectonic effects on the drainage network of the basin, using morphometric indicators. In this research, morphometric quantitative indicators of hypsometric integral ...
