this study was conducted to determine the nutritional value of seaweed gracilariopsis persica and to evaluate its utilization in layer nutrition. metabolizable energy and chemical composition of seaweed were measured. 100 hy-line w-36 hens were allocated to five dietary groups with five treatment group (experimental diets containing zero, five, 10, 15 and 20 percent seaweed) and it lasted for 1...

The objective of this paper is to explore the state-of-the-art in generative process planning as it seems most suitable for the concept of Mass Customization (MC). Particular importance is attributed to special requirements of MC on the practice of process planning as it becomes an integral part of the value chain. Based on the literature review and the extended requirements of MC, the need for...

Multiplicity of the effective factors in drilling reflects the complexity of the interaction between rock mass and drilling bit, which is followed by the dependence of parameters and non-linear relationships between them. Rock mass or, in other words, the formation intended for drilling, as the drilling environment, plays a very essential role in the drilling speed, depreciation of drilling bit...

the present research proposes and optimizes the performance of a novel solar-driven combined cooling, heating, and power (cchp) kalina system for two seasons—winter and summer—based on exergy, exergo-economic, and exergo-environmental concepts applying a non-dominated sort genetic algorithm-ii (nsga-ii) technique. three criteria, i.e. daily exergy efficiency, total product cost rate, and total ...

pectinases have multiple nature and various forms which are necessary for the hydrolysis of pectin in several conventional industrial and natural processes. in this investigation fourteen fungal strains which isolated from agricultural soils ,were screened for pectinase activity. pectinase activity were measured in vitro by assaying released reducing sugar from pectin as sole carbon source. asp...

the influence of the herbivorous snail (physa sp.) on the algal periphyton community from thegamasiyab river, kermanshah province in western iran was examined by establishing a gradient of physa sp.density in artificial streams. the impact of physa grazing was evaluated by measuring dry mass, ash-free drymass (afdm) and chlorophyll a in the periphyton community. snails significantly depressed p...

physical properties are often required for designing post harvest handling and processing equipment for agricultural products. persimmon (khormandy cultivar) is rich in vitamin a, calcium, potassium, tannic acid and antioxidant phenolic compounds. in this study changes in the physical properties of persimmon fruit during storage were studied. properties such as fruit dimensions, mass, geometric...
