Nowadays many studies have focused on food waste. With an expanding population and a wide variety of foods, the sector is always expanding. In addition to production, there also increase in development These wastes result economic difficulties, environmental damage, loss priceless chemical components. The processing fruits vegetables generates most Quince fruit that difficult consume directly u...

This article explores the role of shear-thinning, pseudoplastic non-Newtonian fluids in causation fatal accidents involving hazardous atmospheres. Analysis indicates an appreciable likelihood occurrence structures infrastructure. When subjected to a shear force, such as stirring, stored gas emits from these fluids. Depending on gas, lethal concentrations can develop almost instantaneously. Upon...

The proposed study aims to develop and optimize a topical formulation with Castanea sativa shells extract considering the concept of Quality by Design, focusing on planned development that consider vulnerabilities entire process through risk analysis tools design experiments (DoE). A Box–Behnken three factors levels was used as statistical tool for execution DoE response surface methodology res...

in this study, a computational fluid dynamics (cfd) model was developed to evaluate ultraviolet disinfection applesauce reactor. to simulate uv reactors, three sets of equations, including hydrodynamics, radiation and species mass conservation were solved simultaneously. the realizable k-e turbulence model and the discrete ordinate method were used to find the uv radiation profile through the r...

increasing the thermal stability and resistance to bacterial attack (bioresistance) of the potato starch used in the water-based drilling fluid is the aim of this work. four types of potato starch grafted with acrylamide and a mixture of each one with acrylic acid, 2-acrylamido-2-methyl-1-propane sulfuric acid and itaconic acid were synthesized by manganese (iv)-induced redox system at the suit...

a pressurized fluid extraction (pfe) method for the extraction of pistachio oil was developed using a modified supercritical fluid extractor. the supercritical fluid extraction apparatus was modified to be able to pump liquid solvent and co2 into the extraction vessel alternatively. the experimental results showed that the extraction yield was independent of the extraction pressure. it was also...

treatment of hydrocephalus in posterior fossa tumors in children is still a matter of controversy and different centers have their own routines. in this regard, hospital records of all children with posterior fossa tumors treated in our center during the interval of 1985-1995 were reviewed. patients’ demographic and diagnostic data were analyzed and the frequencies of shunting procedures were d...

mumps infection is endemic in iran. our objective was to evaluate the presence of anti mumps antibodies ( igm & igg) in cerebrospinal fluid in mumps meningoencephalitic children. a prospective/cross-sectional study was performed in tehran, iran (2003 to 2004) and serum anti mumps antibodies (igm) were detected (quantitive; elisa) in meningoencephaltis patients. specific anti mumps antibodies (i...
