Performance measurement is the basis of management with regard to controlling activities of an enterprise. Development of appropriate indicators and measurement techniques lead to many problems. Th e majority of enterprises begin to evaluate the effi ciency, by the implementation of fi nancial indicators that are practically incalculable. Only at a later stage, are measures used that are relate...

This paper develops an index of allocative effi ciency that depends upon the distribution of mark-ups across goods and is separable from an index of standard Ricardian gains from trade. It determines how changes in trade frictions affect allocative efficiency in an oligopoly model of international trade, decomposing the effect into the cost-change channel and the price-change channel. Formulas ...

Bulk heterojunction solar cells (BHJs) based on poly[N-9′′-hepta-decanyl2,7-carbazolealt -5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)] (PCDTBT) can have internal quantum effi ciencies approaching 100% but require active layers that are too thin to absorb more than ∼ 70% of the above band gap light. When the active layer thickness is increased so that the cell absorbs more light, the fi l...

Microbots deliver the goods B y combining two not-so-effi cient DNA delivery systems into one, Demir Akin, Rashid Bashir (Purdue University, Indiana), and colleagues have engineered super effi cient, DNA-delivering “microbots.” Viruses, bacteria, and nanoparticles are used to deliver DNA to cells. But when used in the body, each delivery vehicle has its limitations. Nanoparticles have the advan...

SHAHEEN, M., I. AHMAD, F. M. ANJUM, Q-A. SYED and M. K. SAEED, 2015. Effect of processed rice bran on growth performance of broiler chicks from Pakistan. Bulg. J. Agric. Sci., 21: 440–445 Rice bran was added in broiler chicks feed by replacing 20% maize or 15% wheat. Signifi cant difference in weight gain, feed consumed, feed conversion ratio (FCR), dressing percentage, pancreas weight, feed co...

Light-emitting diodes (LEDs), including organic LEDs and polymer LEDs, have been studied intensively for use in displays and interior lighting due to their promising advantages of high effi ciency, high contrast ratio, long lifetime and low power consumption. [ 1 , 2 ] However, in a conventionally structured LED, less than 20% of the generated light is emitted as useful radiation. [ 3 , 4 ] Not...

We study dynamic bargaining with private information and a deadline. As commitment power disappears, there is a clear "deadline effect" that is, trade takes place smoothly before the deadline and with an atom right at the deadline. Prices, timing of trade and the deadline effect respond to the consequences of not reaching an agreement. Bleaker disagreement options lead to more trade and proport...

Weiss, Fakulty of Mining, Ecology, Process C ontrol a nd G eotechnology, Technical Un iversity o f Ko šice, Slovakia The present paper focuses on the effi ciency improvement of the strategic raw material (iron ore) purchase process in a metallurgical company and its management with the aim to minimize costs. The authors have come up with the proposals for an effi c...
