در این پایان نامه با فرض این که (x,d) یک فضای متری فشرده باشد، ابتدا به معرفی و بیان برخی از ویژگی های جبرهای لیپشیتس lip?(x,d) برای 1 < ? ?0 و جبرهای کوچک لیپشیتس lip?(x,d) برای 1 < ? < می پردازیم. سپس ایده آل های ماکسیمال این جبر ها را بررسی می کنیم. هم چنین وجود نگاشت های خطی، همریختی ها و مشتق های ناپیوسته بر lip?(x,d) را اثبات می کنیم. در ادامه با فرض این که (x,d) و(y,?) دو فضای متری فشرده...
BACKGROUND Shell color polymorphisms of Mollusca have contributed to development of evolutionary biology and population genetics, while the genetic bases and molecular mechanisms underlying shell pigmentation are poorly understood. The Pacific oyster (Crassostrea gigas) is one of the most important farmed oysters worldwide. Through successive family selection, four shell color variants (white, ...
Pearl oyster Pinctada fucata is widely cultured to produce seawater pearl in South China, and the quality of pearl is significantly affected by its shell color. Thus the Pearl Oyster Selective Breeding Program (POSBP) was carried out for the shell color and growth traits. The black (B), gold (G), red (R) and white (W) shell strains with fast growth trait were achieved after five successive gene...
To understand the role that hemocytes play in processes of cellular immunity bivalve mollusks, they should be accurately classified based on their morphological and physiological characteristics. The circulating cultured Pacific oyster (Crassostrea gigas) marine mussel (Mytilus galloprovincialis) were investigated using light microscopy flow cytometry. In mussel, two cell types, granulocytes ag...
This study was conducted to evaluate the calcium (Ca) absorption efficacy of king oyster mushroom (Pleurotus eryngii) grown on sawdust medium supplemented with Ca-sources, including oyster shell powder, and to determine the efficacy of oyster shell powder as a calcium supplement on growth, yield, spawn run and primordial formation of P. eryngii. Optimum calcination of oyster shell powder was ac...
Schistura phamhringi, new stone loach, is described from Dutah Stream, tributary of the Yu River (Chindwin basin), near Larong Village, Chandel District, Manipur, India. It is distinguished from all its congeners by a unique combination of characters: 6-7 black saddles, each continued on both flanks forming broad diamond-shaped black bars with narrow ventral margin; bars superimposed on a grey ...
the effect of microbial load on the condition index of the edible oyster, saccostrea cucullata were analysed on monthly basis during 2010 and 2011 from the three different stations (namkhana, frasergaunge and sajnekhali) of indian sundarbans. the results showed significant variation with respect to microbial load between stations and seasons, which is reflected in the tissue of edible oyster. s...
در این پایان نامه با فرض این که (x,d)یک فضای متریک نافشرده است، ابتدا به معرفی جبرهای لیپشیتس lip(x,d^{alpha})، جبرهای کوچک لیپشیتس lip(x,d^{alpha}) و جبرهای برجست? لیپشیتس lip_{0}(x,d^{alpha}) برای 0<alpha leq 1 می پردازیم و برخی از خواص اساسی آن ها را بیان می کنیم. سپس برخی از قضایای مربوط به فضای متریک r-همبند را بیان می کنیم. در ادامه برخی از ویژگی های فضاهای توابع لیپشیت...
