The equation of motion for the p-polarization field in a wurtzite GaN/AlN multilayer heterostructure is solved for the quasi-confined-optical-phonon modes based on the dielectric-continuum model and Loudon’s uniaxial crystal model. The polarization eigenvector, the dispersion relation of the...

Using an oligopolistic international trade model, which consists of three countries (A, B, and C) and three goods (two differentiated oligopoly goods and the numeraire), we examine (i) the structures of the countries’ incentives to form free trade agreements (FTAs); (ii) the pairwise stability...

The objective of this study was to assess the quantity and quality of biogas produced by co-digesting flushed dairy manure (FDM) and turkey processing wastewater (TPW). An attached growth digester with working volume of 15 L and a 3 L head space was operated at a 5 d hydraulic retention...

Global markets and the increasing demand of customers for individual products lead to a steady rise of product variants. Especially high quality goods on highly competitive markets like automobiles must meet customer's demands. The opportunity to configure a car according to ones' preferences...

Plant water status is a key factor impacting crop growth and agricultural water management. Crop water stress may alter canopy temperature, the energy balance, transpiration, photosynthesis, canopy water use efficiency, and crop yield. The objective of this study was to calculate the Crop Water...
