the aim of this study was to investigate the range utilization of rhode island red hens, grazing outdoor (under tropical conditions) and to scan their activities inside the house as well as during their outdoor visits. the activities of rir hens, raised in indoor floor pens connected with outdoor areas covered with natural vegetation, were scanned and recorded individually within 15 minute inte...

Ectomycorrhizal fungi are considered to play an essential role in the development of forest ecosystems and can protect plant against pathogenic infections. Among other factors, soil pH may affect successful inoculation seedlings nurseries. The effect on growth rate strains nine species edible ectomycorrhizal (ECM) was evaluated vitro. In experiments, Boletus edulis, B. aereus, pinophilus, fragr...

In this paper, we construct the new integral representation of Jost solution Sturm-Liouville equation with impuls in semi axis $[0,+\infty )$ and give type relation, examine properties Kernel function their partial derivatives $x$ $\ t$, constructed obtain differential provided by function. Finally, paper prove uniqueness determination potential scattering data.

Rock glaciers are receiving increased attention as a potential source of water and indicator climate change in periglacial landscapes. They consist an ice-debris mixture, which creeps downslope. Although rock wide-spread feature on the Tibetan Plateau, characteristics such its ice fraction unknown superficial debris layer inhibits remote assessments. We investigate one glacier semiarid western ...
