The growth pattern and reproductive biology of Acanthopagrus latus were studied to derive information required for their management in the south part of Iran, Persian Gulf. Samples collected monthly from October 2014 to September 2015. Parameter values of the Von Bertalanffy growth function fit to length frequency data (males and females combined) were estimated as k = 0.23 per year, L∞ =50.4 c...

This experiment was carried out to investigate the effect of feeding different levels of luffa aegyptiaca extracts (LAP) on the growth performance of broiler chicken fed corn-soya meal diet. The study was carried out between January to March, 2019. A total of two hundred day old broiler chicks of mixed sex (Ross 308) were allocated into four treatment groups, each group was further divided into...

The aims of this study were the comparative study of probiotic, acidifier,antibiotic growth promoters and prebiotic on activity of humoral immune and performance parameters of broiler chickens.500 one day old male broilers (308 Ross strain) were divided into 5 groups: A, B, C, D and E. Each group with equal numbers of male included 4 replicates (25 chicks per replicate). Group A was as control ...

Shrimp aquaculture has expanded rapidly in many countries and this rapid development resulted diseases outbreaks and further considerable utilization  of antibiotics. Use of natural products as antimicrobial has been reported as a resolution problem. The crude extract of a red seaweed (Laurencia snyderiae) collected from the Persian Gulf was evaluated for shrimp growth performance and to d...

— Various model parameter calculation equations of RF CMOS inductors are compared. The calculation equations are using as variables either Y, Z-parameters or S-parameters. Results are based on on-wafer RF S-parameter measurements of a 3.75 turn spiral inductor fabricated in AMIS 0.7 μm CMOS DM1P n-well technology. Results obtained with calculation equations for a differentially driven inductor ...
