abstract water pricing is a policy instrument for improving water efficiency, reducing water demand, management of the irrigation systems and recovering costs. the underlying principle of water pricing is that it should reflect the opportunity cost of water. in this study, parametric mathematical programming approache were used to estimate the willingness of farmers to pay for groundwater under...

Todays, parallel to growing in acceptance of functional products, various additives are used to improve the characteristics of functional food products. The coenzyme Q10 is an essential component for energy conversion and production of adenosine triphosphate (ATP) in the membranes of all body cells and organelles, especially the inner mitochondrial membrane is found. Coenzyme Q10 plays a vital ...

coenzyme q10 is a promising   agent for neuroprotection in neurodegenerative   diseases. neuroprotective effects of coenzyme q10 demonstrated in some   neurodegenerative diseases such as parkinson, alzheimer and etc. hippocampus   is home of these diseases. we assayed coenzyme q10 effects on hippocampal   injury model and our hypothesis is that coenzyme q10 has neuroprotective   effects in some...

In his 1998 paper, Ryan classified the sets of unit, proper, and plain trapezoid and parallelogram orders. We extend this classification to include unit, proper, and plain triangle orders. We prove that there are 20 combinations of these properties that give rise to distinct classes of ordered sets, and order these classes by containment.
