Backtracking search algorithm is a novel population-based stochastic technique. This paper proposes an improved backtracking search algorithm for constrained optimization problems. The proposed algorithm is combined with differential evolution algorithm and the breeder genetic algorithm mutation operator. The differential evolution algorithm is used to accelerate convergence at later iteration ...

HCPB (Helium Cooled Pebbles Bed) Test Blanket Model (TBM) is based on solid breeder. Tritium has to be extracted using Helium purge gas flowing through breeder pebbles bed. He-stream must be cooled down and processed and all these steps are carried out in TES (Tritium Extraction System). A modeling work has been performed to study the behavior of the TES of the HCPB TBM and for Molecular Sieve ...

ally disordered parent, he lacks the ability to think clearly, comprehend communicate and solve problems in an increasingly complex world. Thus, " breakdowns" occur at times of greatest stress (e.g., separation from home or cotwin, death of a grandparent, etc.) when his limited resources are overtaxed to the point of disorganization. By way of contrast, the cotwin has many more cognitive, commu...

In this paper I discuss what I think of as the “modalities of time” involved in a development project in the High Atlas Mountains, Morocco. By “modalities” I mean the understandings of time held by the different actors involved, but also the timeframes relevant to various social dynamics impacted by the project. Max Gluckman discussed such timeframes in terms of “structural duration,” the perio...

The effects of environmental temperature (ET) and dietary ME on core body temperature (CBT) and production efficiency were evaluated in broiler breeder hens. A total of 192 Ross 708 broiler breeder hens were individually caged in one of 6 temperature-controlled chambers (32/room) at 20 wk of age. A biotelemetry sensor was surgically implanted abdominally to measure CBT of 8 birds/tmt every 10 m...

To those who carefully observe the sport though, there clearly are factors at work which contribute to the success of the winning bird. We all have known of those rare and exceptional birds that have amassed astonishing records. We have known or read of handlers who can consistently place near the top. We have known or read of breeders who consistently produce top birds. These amazing feats def...

RapidAPIIS is free software developed in the APIIS framework for setting up integrated databases of individual animal records. It is intended for scientists, students and breeders in the animal agriculture with no programming experience. The user can choose from variety of templates for various species and customize them by including the traits recorded within her/his their organization. Thus, ...

avian leukosis virus subgroup-j (alv-j). mycoplasma gallisepticum (mg) and mycopjasma synviae (ms) are important pathogens in chickens that cause severe economical losses in poultry industry throughout the world. seven broiler grandparent flocks of iran (six broiler strains) were sampled randomly at the ages of 8-63 wk (100 samples from each flock) for antibody detection to alv-j, mg, and ms by...
