IMPORTANCE In youth, facial aesthetic units flow together without perceptible division. The face appears as a single dynamic structure with a smooth contour and very little if any shadowing between different anatomical regions. As one ages, facial aesthetic units slowly become distinct. This process may be a consequence of differences in skin thickness, composition of subcutaneous tissue, conto...

The Allam cycle is a novel that capitalizes on the unique thermodynamic properties of supercritical CO2 and advantages oxy-fuel combustion for power generation capture. This study aims to confirm outstanding performance coal-fired with aid an exergetic analysis provide detailed important information real inefficiencies within cycle. results show overall efficiency 40.6%, near 100% carbon highes...

Air separation units are one of the prime examples for studies on demand side management and (non-)linear model predictive control due to their high power consumption energy storage potential. These plants separate ambient air into its main components, nitrogen, oxygen, argon, by means cryogenic distillation at different pressure levels. Approximately two thirds industrially operated consider a...

introduction iran is a frontier of pomegranate fruit production in the world (with almost 40 % of the world`s production). however due to traditional processing operations is not ranked as the largest pomegranate exporter. saveh, neyriz and ferdows are the top pomegranate producing cities in iran. pomegranate is consumed as a fresh fruit as well as processed product as food additive, paste, syr...

 A model is developed for separation of multicomponent gas mixtures in a countercurrent hollow fiber membrane module. While the model’s solution in countercurrent module usually involves in a time consuming iterative procedure, a proper initial guess is proposed for beginning the calculation and a simple procedure is introduced for correcting the guesses, hereby the CPU time is decreased ess...

The separation of dissolved gas including dissolved oxygen can be used in breathing for a human under water. When one is suddenly wrecked or meets a tsunami, one is instantly drowned and cannot breathe under water. To avoid this crisis, when we meet waves, the dissolved gas separated from water by wave is used, while air can be used to breathe when we are about to escape from water. In this the...

In traditional raised-floor data center design with hot aisle and cold aisle separation, the cooling efficiency suffers from recirculation resulting from the mixing of cool air from the Computer Room Air Conditioning (CRAC) units and the hot exhaust air exiting from the back of the server racks. To minimize recirculation and hence increase cooling efficiency, hot aisle containment has been empl...
