objective: ageing of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. accelerated ageing has been recognized as a good predictor of the storability of seed lots. aged seeds show decreased vigor and produce weak seedlings that are unable to survive once reintroduced into a habitat. the characteristics of the chemical composition of...

this study was carried out to investigate the effects of salinity levels (0, 2, 4, 7 and 10 ppt) on growth indices, blood biochemical parameters, and body composition in rutilus frisii kutum fingerlings (initial weight 1.330.02 g) during 60 days. results indicated that the highest rates of daily growth, specific growth and weight gain per fish were obtained at the levels of 4 and 2 ppt (p0.05)...

saffron (zaaferan), botanical name crocus sativus, is the most expensive spice in the world. it is derived from the dried stigma and pistil of the purple saffron crocus flowers. iran is the largest saffron producer accounting for more than 80% of the world's production. saffron contains an aeroallergen that causes reactive respiratory allergic reactions in atopic subjects. igg antibody to aller...

this study was evaluated to study the effects of vitamin c and the bacteria bacillus subtilis, b.lichniformis on growth and carcass composition of litopenaus vannamei. three treatments were applied, treatment fed with probiotics (4×1010 cfu/kg food), treatment with vitamin c (140 mg/kg food) and the control group. three replicates were used for each treatment. shrimps were kept in nine 300-lite...

In this study, the composite material with composition of MgH2-5 wt% SiC has been prepared by co-milling of MgH2 with SiC powder. The effect of milling time and additive on MgH2 structure, i.e. crystallite size, lattice strain, particle size and specific surface area, and also hydrogen desorption properties of obtained composite was evaluated by thermal analyzer method and compared with pure un...

Researchers at the South African Medical Research Council used the Bangkok Declaration, Thailand, 2009, as a guideline for their food composition activities. The vision is to build a comprehensive food composition database for the country. Activities are directed at increasing the number of food items with country-specific nutrient information; encouraging research organisations, universities a...

In this paper, we discuss a way of composing a system from components where the dependencies between the components are not explicitly known. We make observations based on our experience with defining and implementing a composition mechanism for layered architectures. We propose a manner of specifying component descriptions to express anonymous dependencies between the components, an applicatio...

Advances in computer networks that support the invocation of remote services in heterogeneous environments enable new levels of software composition. In order to manage composition at such a high level we envision a need for purely compositional languages. We introduce the CLAM composition language, a megaprogramming language. By breaking up the traditional CALL statement the CLAM language focu...
