Direct reproductive traits as they are currently measured tend to be low in heritability, making the environment a beef female is produced in key to reproductive success. Large cow size and high milk production translate into increased energy and protein requirements for the cow, even when not lactating. The increased nutrient requirements can significantly limit the carrying capacity of any fa...

BACKGROUND Gray whales (Eschrichtius robustus) undertake long migrations, from Baja California to Alaska, to feed on seasonally productive benthos of the Bering and Chukchi seas. The invertebrates that form their primary prey are restricted to shallow water environments, but global sea-level changes during the Pleistocene eliminated or reduced this critical habitat multiple times. Because the f...

Ekolojik taşıma kapasitesi ekosistemlere zarar verilmeden ortamdan üst düzeyde yararlanma ölçütünü tanımlar. Her ekonomik faaliyet gibi su ürünleri yetiştiriciliğinin de sucul ekosistemler üzerine önemli etkileri bulunmaktadır. Özellikle yüzer ağ kafes balık çiftlikleri yerleşim konumu gereği ortama besleyici element vererek ötrofikasyona neden olabilir. Bu nedenle kurulmadan önce ortamın hesap...

Comparative developmental studies have revealed a rich array of details about the patterns and processes of morphological change in animals and increasingly in plants. But, applying these insights to the study of major episodes of evolutionary innovation requires understanding how these novel morphologies become established and sufficiently abundant (either as individuals within a species or as...

The calculation of the load carrying capacity of variable thickness circular plates subjected to arbitrary rotational symmetric loading is presented. The analysis considers plate materials that obey either the square or the Tresca yield criterion. By using upper and lower bound theorems of limit analysis, corresponding estimations for the load carrying capacity of the plate are obtained. It is ...

this paper proposes a control strategy for a cable-suspended robot based on sliding mode approach (smc) which is faced to external disturbances and parametric uncertainties. this control algorithm is based on lyapunov technique which is able to provide the stability of the end-effecter during tracking a desired path with an acceptable precision. the main contribution of the paper is to calculat...
