Thermal stability of cation exchange, PFA-g-polystyrene sulfonic acid membranes prepared by radiation-induced graft copolymerization of styrene onto PFA films followed by sulfonation was studied by thermal gravimetric analysis (TGA) and oven heat treatment. The tested samples included original and grafted PFA films as reference materials. All the membranes showed multistep decomposition pattern...
Today, there is an increasing interest in the use of metal nanoparticles in health sciences. Amongst all nanoparticles, the gold nanoparticles have been known to kill the cancer cells under hyperthermic condition by near-infrared frequency electromagnetic waves. On the other hand, although there are different physiochemical methods for disinfection of microbial pollution, however applications o...
The aim of this study was to develop a concept, within the framework sustainable agriculture, for utilizing apple pomace as valuable raw material in food production. proposal includes description production technology four products together with characteristics their chemical composition, wholesome compounds, and physical properties. These new were developed on basis wheat bran. In technology, ...
This research deals with heat and mass transfer in biscuit industrial baking ovens. In these ovens, heat reaches biscuits indirectly by radiation, convection and conduction. The method for numerical solution is that we first provide the related equations, then they are discretized by finite difference method (FDM), and finally, after encoding and writing a program for the computer, we run it. T...
Dill (Anethum graveolens L.) and parsley (Petroselinum crispum Mill.) were dried by using sun and oven (50oC) drying methods. Oven drying decreased the drying time approximately 50% when compared to the sun drying method for both herbs. K, Ca, P, Mg and Na were the most abundant elements in dill and parsley samples. Oven-dried samples had higher mineral values than that of the su...
Background and Objective: Inappropriate atmospheric conditions are harmful factors that cause particular problems in certain seasons (summer or winter). The occupation of confectionery in the regions like Ilam causes severe problems due to the heat generated by the nature of the work (synthetic heat-generating processes) and the heat resulting from the climatic conditions in the region. Exposur...
UNLABELLED From 1995 to 2004, in Genoa, Italy, daily concentrations of twelve polycyclic aromatic hydrocarbons (PAHs) were measured in particulate phase (PM10), around a coke oven plant in operation from the 1950s and closed in 2002. The study permitted to identify the coke oven as the main PAH source in Genoa, causing constant exceeding of benzo(a)pyrene (BaP) air quality target (1.0 ng/m3) in...
Background: Drying is the most common way to preserve quality of aromatic and medicinal plants. Chosen drying methods can affect on the essential oil content and composition of medicinal plants. Objective: This study aimed to assess the changes in essential oil constitutes of catnip aerial part under various drying methods. Methods: The experiment was performed as the randomized complete ...
