The mathematical study known as queueing theory has recently become a major point of interest for many government agencies and private companies increasing efficiency. One such application is vehicle at an international port-of-entry (POE). When queueing, fumes from idling vehicles negatively affect the overall health well-being community, especially U.S. Customs Border Protection (CBP) agents ...

Potassium permanganate (KMnO4) is a dominant ethylene (C2H4)-scavenger extensively used in fresh horticultural commodities, mainly climacteric fruit, to prolong their shelf life. This material has been traditionally utilized as C2H4-permeable sachet for inclusion into packages of produces. New formulation strategies are required polymeric materials develop nanocomposites with scavenging potenti...

In this experimental study, the results of utilizing a nano-lubricant in place compressor work fluid refrigeration system were examined. R134a refrigerant was utilized system. Polyol ester (POE) used as base and prepared from alumina oxide (Al2O3) nanoparticles utilized. The experiments carried out separately with nano-lubricants created by mixing Al2O3 ratios 0.5% 1.0% into POE oil. Additional...
