detopping in some plants reduces vegetative growth and increases transporting of photosynthate materials to specific sinks such as seeds. to study the effects of detopping removal and plant density on yield and yield components of faba bean (vicia faba l.), an experiment was carried out as a factorial arrangement based on a randomized complete block design with three replications at farm resear...

We present conclusions from a large number of N-body simulations of the giant impact phase of terrestrial planet formation. We focus on new results obtained from the recently proposed Grand Tack model, which couples the gas-driven migration of giant planets to the accretion of the terrestrial planets. The giant impact phase follows the oligarchic growth phase, which builds a bi-modal mass distr...

Turnip Yellow Mosaic Virus RNA directs the synthesis in vitro of its coat protein in a wheat germ cell-free extract. Optimum conditions for synthesis have been defined, and the effect of spermine on specifically enhancing coat protein formation has been examined. Identity between the in vitro synthesized coat protein and authentic coat protein of Turnip Yellow Mosaic Virus was established by an...

1. Abstract Phase separation in segmented polyurethanes is an important phenomenon, which affects on characteristic properties of polyurethanes. Morphology, formation and distribution of micro-domains (hard segments and soft segments) are effective parameters on interfacial interaction and adhesion of polyurethane system. In this work segmented polyurethanes based on 4,4 -diphenylmethane diisoc...

The secretion of vesicles for intracellular transport often relies on the aggregation of specialized membrane-bound proteins into a coat able to curve cell membranes. The nucleation and growth of a protein coat is a kinetic process that competes with the energy-consuming turnover of coat components between the membrane and the cytosol. We propose a generic kinetic description of coat assembly a...

OBJECTIVE Qingyu pig, a Chinese indigenous pig breed, exhibits two types of coat colour phenotypes, including pure black and white with black spotting respectively. Melanocortin receptor 1 (MC1R) and agouti signaling protein (ASIP) are two widely reported pivotal genes that significantly affect the regulation of coat colour. The objectives of this study were to investigate whether the polymorph...

The spatial arrangement of COPII coat protein subunits was analyzed by crosslinking to an artificial membrane surface and by electron microscopy of coat proteins and coated vesicle surfaces. The efficiency of COPII subunit crosslinking to phospholipids declined in order of protein recruitment to the coat: Sar1p > Sec23/24p >> Sec13/31p. Deep-etch rotary shadowing and electron microscopy were us...

A new Ultra Violet (UV) curable solution acrylic polymer based technology has been under development for manufacturing optically clear pressure sensitive adhesives. Monomers, functional groups, and formulating components can be selected to modify and tailor product properties for specific optically clear end uses. Refractive index, outgassing, heat resistance, and humidity resistance among othe...
