This paper studies and characterizes a solar collector with spherical geometry to produce hot water for sanitary domestic applications other facilities. The new enlarges the surface allows full sun tracking during day without needing system. Although this has been in use some time, its market penetration is low due lack of perfect knowledge behavior benefits compared conventional collectors. ca...

objective(s): the purpose of the present study was to prepare and to evaluate a novel niosome as transdermal drug delivery system for propranolol hydrochloride and to compare the in vitro efficiency of niosome by either thin film hydration or hand shaking method. materials and methods: niosomes were prepared by thin film hydration (tfh) or hand shaking (hs) method. propranolol niosomes were pre...

Current study was carried out to assessment the effects of zeolite on seed yield, physiological and biochemical traits of sorghum in response to different irrigation regime according split plot arrangement based on complete randomized block design with three replications in Varamin region (Central of Iran). The main plots consisted of different irrigation regime at four levels [Normal irrigatio...

This paper presents a robust scalable video coding scheme with leaky prediction, suitable for time-varying error-prone channels, such as the Internet or wireless channels. The proposed scheme shows how leaky prediction can be utilized for efficient motion-compensated video coding, as well as for robust video transmission over packet erasure networks. We show that leaky prediction with a tempora...

Real-time quantitative PCR (qPCR) for rapid and specific enumeration of microbial agents is finding increased use in aerosol science. The goal of this study was to determine qPCR accuracy, precision, and method detection limits (MDLs) within the context of indoor and ambient aerosol samples. Escherichia coli and Bacillus atrophaeus vegetative bacterial cells and Aspergillus fumigatus fungal spo...

To reduce carbon dioxide emissions into the environment, energy sector develops oxygen-fuel cycles. One of most promising cycles is Allam cycle that features highest efficiency electricity generation among all others. main elements an oxy-fuel a high-temperature turbine. The turbine’s working fluid and coolant consist predominantly at supercritical pressure. Currently, there are no recommendati...
