Spatial variability of the aspect sensitivity of VHF radar echoes in the troposphere and lower stratosphere during jet stream passages

The aspect sensitivity of SOUSY-VHF-radar oblique-beam echoes from the troposphere and lower stratosphere has been examined for a number of jet stream passages during the years 1990 - 1992.When the core of the jet is overhead or nearly so, vertical profiles of the aspect Keyboards sensitivity display two notable features.First, the distinction betw

Maternal mRNA input of growth and stress-response-related genes in cichlids in relation to egg size and trophic specialization

Abstract Background Egg size represents an important form of maternal effect determined by a complex interplay of long-term adaptation and short-term plasticity balancing egg size with brood size.Haplochromine cichlids are maternal mouthbrooders Commercial Product (Controls/Chemical Automation) showing differential parental investment in different

Study on Action Mode of Sphingosine 1-Phosphate in Rat Hepatocytes

Sphingosine-1-phosphate (S1P) acts on a set of G protein-coupled receptors in the plasma membrane and also as a second messenger in certain cell types.There are two possible pathways to mobilize intracellular Ca2+ concentration by S1P.One is through phospholipase C, SOD and the other is through intracellular Ca2+ channels operated by S1P.The Mn2+ q
