fish oil is the important fat source in fish nutrition. high demand for fish oil and low global supply arise a need of alternative oils in fish culture. plant oils are a good candidate in this case. the aim of the present study was to compare the efficacy of fish oil and linseed oil on growth and stress resistance of tiger barb ( puntius tetrazona ) larvae. artemia nauplii were enriched by 2.5,...

production of chicken meat is an important branch of food industry. generally, poultry meat farmers aim to produce birds with superior body weight and feed conversion ratio. however, in line with current developments, there are other parameters that must to be taken into account such as lower body fat deposition and improvement in the nutrient composition of products corresponding to consumer r...

The biodiversity loss of phytoplankton with eutrophication has been reported in many aquatic ecosystems, e.g., water pollution and red tides. This phenomenon seems similar, but different from the paradox of enrichment via trophic interactions, e.g., predator-prey systems. We here propose the paradox of enrichment by induced competitive interactions using multiple contact process (a lattice Lotk...

Nineteen carbon stars that show lithium enrichment in their atmospheres have been discovered among a sample of 674 carbon stars in the Large Magellanic Cloud. Six of the Li-rich carbon stars are of J-type, i.e., with strong C isotopic features. No superLi-rich carbon stars were found. The incidence of lithium enrichment among carbon stars in the LMC is much rarer than in the Galaxy, and about f...

In this study, a 3D combustion chamber was simulated using FLUENT 6.32. Aims to obtain accurate information about the profile of the combustion in the furnace and also check the effect of oxygen enrichment on the combustion process. Oxygen enrichment is an effective way to reduce combustion pollutant. The flow rate of air to fuel ratio is varied as 1.3, 3.2 and 5.1 and the oxygen enriched flow ...

Molecular recognition is a complex process that involves a large ensemble of structures of the receptor and ligand. Yet, most structure-based virtual screening is carried out on a single structure typically from X-ray crystallography. Explicit-solvent molecular dynamics (MD) simulations offer an opportunity to sample multiple conformational states of a protein. Here we evaluate our recently dev...

This paper is introduces RC4 Enrichment Algorithm Approach for selective image encryption. This approach is derived from the standard RC4 algorithm. RC4 algorithm is already used for image encryption and also for the selective image encryption. Currently RC4 is vulnerable. Lots of cryptanalytic found the lots of weakness, vulnerable point and attacks inside the RC4 algorithm. So in this concern...

Urban ecosystems are carrying an extinction debt. Mitigating this debt will require the development of a predictive framework that improves our understanding of the factors causing decline of native biodiversity in urban areas. I argue that nitrogen is a common currency around which such a predictive framework could be built. I first summarise the evidence that shows the probable extent of nitr...

The testing phase is becoming the most crucial part of the overall design process, which delays the timeto-market of the digital devices. In order to reduce the complexity of test generation and to decrease the time-tomarket, one needs to begin the test design at higher levels of abstraction. In this paper a new approach for functional delay test enrichment is described. The test enrichment pro...

A culture method to detect non-O157 Shiga toxin-producing Escherichia coli (STEC) was optimized in this study. The finished dairy compost with 30% moisture content was inoculated with a cocktail of six non-O157 STEC serovars at initial concentrations of 1 to 100 CFU/g. Afterward, non-O157 STEC cells in the inoculated dairy compost were enriched by four methods, followed by plating onto cefixime...
