This study was conducted to produce a high percentage of genetically male tilapia through interspecific hybridization between Nile tilapia, Oreochromis niloticus and Blue tilapia, O. aureus and evaluate sex ratio, productive performance and heterosis of the progeny produced. The results revealed that sex ratios of the progenies of (♀ O. aureus x ♂ O. niloticus) and (♀ O. niloticus x ♂ O. aureus...

CONTEXT Common pain conditions appear to have an adverse effect on work, but no comprehensive estimates exist on the amount of productive time lost in the US workforce due to pain. OBJECTIVE To measure lost productive time (absence and reduced performance due to common pain conditions) during a 2-week period. DESIGN AND SETTING Cross-sectional study using survey data from the American Produ...

A cross-sectional comparative study was carried out to investigate the productive and reproductive performances of different genetic groups of crossbred cows at three different farming conditions in Bangladesh. Crossbred cows (n=90) those already completed third lactations, were selected randomly from three different dairy farms (e.g. Jarip, Mullah and Nahar) located in Chittagong, Bangladesh. ...

this experiment was carried out at the college of agriculture university of salahaddin erbil. to study the effect of water supplementation with propolis on local quail performance, some physiological and immunological characteristics at 42 days old. a total of one thousand fifty (1050) hatched local quail eggs that obtained from the project of al-rashedia for agriculture researches center in mo...

six hundred day old unsexed broiler chicks were used in a 42-d trial at chittagong veterinary and animal sciences university poultry farm to find out the effects of different oils on productive performance of broilers. the chicks were randomly distributed following a completely randomized design in four treatment groups having three replications per treatment. each treatment had 150 birds, with...

RISC-V is a new instruction-set architecture that encourages users to design new domain-specific extensions for their needs. This necessitates RISC-V instruction-set simulators that allow productive development, productive extension, and productive instrumentation. In addition, these simulators need to be high-performance to allow simulating real-world benchmarks. There is a productivity-perfor...

When an agent overstates his/her true performance, a rational market can simply discount the reported performance, and correctly guess the true performance. This paper shows, however, that such rational market discounting leads to less productive effort by the agent and less performance-pay by the principal. Therefore, a rational market and a profit-maximizing principal can exacerbate the lack ...
