Price postponement is an effective mechanism to hedge against the adverse effect of supply random yield. However, its effectiveness and resulting production decisions have not been studied for risk-averse firms. In this paper, we investigate impact price risk aversion under yield risk. Specifically, study a monopoly firm’s pricing with two distinct schemes: (1) ex ante in which firm simultaneou...

The x-ray emission with the single crystal of lithium niobate (LiNbO3) or lithium tantalite (LiTaO3) by thermal changes in a vacuum system is closely concerned with the electronic state of each crystal. Therefore, lithium Kedge x-ray absorption near edge structures (XANES) spectra of these materials were measured in the region from 50 eV to 90 eV by means of total electron yield method (T.E.Y.)...

Microbial electrolysis cells (MECs) provide a high-yield method for producing hydrogen from renewable biomass. One challenge for commercialization of the technology is a lowcost and highly efficient cathode. Stainless steel (SS) is very inexpensive, and cathodes made of this material with high specific surface areas can achieve performance similar to carbon cathodes containing a platinum cataly...

BACKGROUND The risk of colorectal cancer is higher among relatives of those affected. The neoplastic yield reported from screening such individuals varies enormously between studies and depends on the age and strength of the family history of those screened. AIMS To ascertain the neoplastic yield of endoscopic screening of first degree relatives of patients with colorectal cancer by age and f...

Significant time-varying risk premia exist in the foreign currency futures basis, and these risk premia are meaningfully correlated with common macroeconomic risk factors from equity and bond markets. The stock index dividend yield and the bond default and term spreads in the U.S. markets help forecast the risk premium component of the foreign currency futures basis. The specific source of risk...

BACKGROUND American College of Cardiology/American Heart Association appropriate use criteria recommend performing stress myocardial perfusion imaging (MPI) for intermediate- to high-risk patients presenting with syncope but not for low-risk patients. However, there are limited data to support these recommendations. We investigated the yield of stress MPI for the evaluation of syncope in patien...

Rice consumption is a major dietary source of Cd and poses potential threat to human health. The aims this study were examine the influence Fe application on yield components, dynamics in pore water, translocation factors, daily intake, estimation health risks. A pot experiment was performed under glasshouse conditions where rice cultivars (Langi Quest) cultivated two dissimilar soils different...
