to use narrower slits and thus a more nearly monochromatic source and at the same time work more rapidly. Figure 2 shows values of a plotted against X. These results show very clearly the type of anomalous dispersion occurring near a K absorption limit. It is of the form predicted by the theories of Kronig and of Kallmann and Mark. It is doubtful that a quantitative agreement exists. For one th...

Inrecent efforts to improve the performance ofwhite light-emitting diode (WLEDs), researchers have focused on angular color uniformity (ACU), an effective index for evaluating light quality of WLEDs. Inthis article, we also aim WLED development by applying three phosphor layers in remote structure. The dual-layer (DLP) structure is included research comparison with triple-layer (TLP) terms thei...

For this reason, study aimsto investigate analyze a number factors that cause competitiveness such as quality ofservice, technology information systems knowledge management on competitiveadvantages companies. population research sample are all companiesbetween c...

Complaint behavior is a person's response to dissatisfaction with the goods or services used. Complaints are feedback from customers that tend be negative towards company. Self-confidence can interpreted as one aspect of personality in form belief one’s abilities so others do not influence him, act according his will, happy, optimistic, relatively tolerant, and responsible. This study generally...

10-HDA (10-hydroxy-2-decenoic acid), an unsaturated medium-chain fatty acid in royal jelly, has been shown to possess biological activity in many fields, including the prevention of cardiovascular disease, cancer, bacteria and radiation. Inthis study, the antibacterial activity of 10-HDA againstE.coli was evaluated. Meanwhile, the acting mechanism of 10HDA on E. coli was investigated by analyzi...

Today, along with enhancement of social well-being andeconomic development, demand for transportation is growing increasingly.Many countries are seeking for providing transportation servicesat a reasonable price. Therefore, optimization of carrying goods on nationalor international roads is highly important in terms of costs andtransportation indicator, so that the goods are shipped at minimumc...

Inthis article we offer a method of ranking contractors by using DEA based onanalysis deficit and AHP. The process of hierarchical analysis (AHP) byproviding scales from paired comparison matrix, performs the contractor’sprioritizing choice. But AHP has some problems and to solve those problems,Jahanshahloo and his colleagues presented a new model which uses DEA andstandard deviation. In this a...

A complex set of extracellular signals is required for neural crest (NC) specification. However, how these signals function to coordinate cell cycle progression and differentiation remains poorly understood. Here,we report inXenopus a role forStat3 inthis process downstream of FGF signaling. Depletion of Stat3 inhibited NC gene expression and proliferation while its overexpression expanded the ...
