Introduction: The terrestrial planets formed by collisional accretion of small planetesimals [1,2]. Stochastic coagulation and runaway growth yield an “oligarchy” of embryos with similar sub-planetary masses [3] that then collide to yield planets [4-5]. A common assumption is km-sized initial planetesimals, based on the scale of gravitational instability in a dust layer in a quiescent solar neb...

Electrochemistry is a very useful technique to generate surface enhanced Raman scattering (SERS) substrates. SERS depends on two mechanisms: the electromagnetic effect, related plasmonic properties of nanostructures in substrate, and chemical mechanism, interaction between target molecule substrate. Thus, enhancement for strongly nature that form In this work, time-resolved spectroelectrochemis...

Information on variations in crop yield among farmer fields in a specific area and theircausal factors is important for efficiently targeting efforts to increase production of the crop inthe target area. This study determined the yield variations and their causal factors for sugarcanegrown in the service area of a sugar mill in Northeast Thailand. Two villages with the dominantsandy and clayey ...

in order to study the effect of mallow weed competition and nitrogen (n) rates on grain yield and yield components of wheat cv. chamran, a field experiment was conducted in 2009. the experiment was designed as a split-plot with three replications and additive series. the n application rates were assigned in the main-plots (50, 100, 150 and 200 kg.n.ha-1) and sub-plots consisted of target common...

Erosion of carbon based materials plays a very crucial role in determining its candidature as a potential plasma facing material in fusion devices. Carbon erosion yield shows strong dependence on energy, flux of the incoming ions and the target temperature. Various experiments and theoretical models have made successful attempts to understand some aspects of the erosion mechanism of carbon bomb...

A rice tiller is a specialized grain-bearing branch that contributes greatly to grain yield. The MONOCULM 1 (MOC1) gene is the first identified key regulator controlling rice tiller number; however, the underlying mechanism remains to be elucidated. Here we report a novel rice gene, Tillering and Dwarf 1 (TAD1), which encodes a co-activator of the anaphase-promoting complex (APC/C), a multi-sub...

Herbicides play an important role in preventing crop yield losses due to both their weed interference ability and capacity for increasing soil conservation no-till systems. Group A herbicides or acetyl-CoA carboxylase (ACCase) are essential tools the selective management of glyphosate resistance grass species. In this review, we describe aspects ACCase biology targeting enzyme, along with a dis...

understanding the implication of genotype-by-environment interaction (gei) and improving stability of crop yield in a target production environment is important in plant breeding. in this research, we used the ammi (additive main effects and multiplicative interaction) model to identify the stable genotype(s) by predictive accuracy of yield data. results of this study indicated that the fgh tes...
