in this study, the effect of edible coat (carboxy methyl cellulose) before osmotic dehydration anddifferent drying methods on sensory and physical properties of dried apple (v. golden delicious)rings was investigated. the coated and non-coated samples pretreated with 50% sucrose osmoticsolution and dried in freeze drier (-40 to -50°c, 0.026-0.017 mbar, 24 hr), vacuum drier (70°c, 200mbar, 8-10 ...

this research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. this experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of chenran township. the results ...

nowadays, polymer blends usages increase more and more in order to produce materials with better properties. according to many research works, the blends of polyolefins have shown industrial importance. the purpose of this project was to carry out some investigations on fibers melt spun from the polypropylene and low density polyethylene blends. pp and ldpe are immiscible. pp/ldpe blend filamen...

the growing interest in using natural fibers as reinforcing agents of polymer-based composites is mainly due to their advantages such as lower cost, lower density, ease of preparation, lower energy requirements for processing, biodegradability, wide availability and relative non-abrasiveness over traditional reinforcing fibers such as glass and carbon. in this study, wood-plastic composite (wpc...

The inkjet printing machine was initially used on ceramic parts as a small device in designing and advertising offices limitedly. In recent years, this device has been applied professionally to create high-quality patterns in the industry. In this method, liquid ceramic ink is sprayed on the specified parts by piezoelectric nozzles and after drying and discharging, the organic matter is baked a...

producing parts with high density and improved mechanical properties is one of the most important aims of powder metallurgy process. there are many factors for attaining modified properties in sintered parts but among them controlling type and quantity of alloying elements and manufacturing parameters such as compacting pressure, sintering temperature are the most effective.in this research, tw...

cattle manure is made from liquid and solid waste. it contains the straw and stubble that is used for the cattle bed. density of the cattle manure is inherently low, which is difficult and costly to transport. pelleting is one method to solve this problem. the physical properties of the pelleted cattle manure was investigated in this study. the results showed that by increasing moisture content...

annual fires might change many soil physical properties in semi steppe rangeland.the objective of this study was to investigate the impact of fire on soil physical properties and soil water infiltration parameters in semi-steppe rangeland of karsanak region in chaharmahal and bakhtiari province. therefore, several sites were chosen which were affected by fire at three, two and one years prior t...
