development of feminist poetics in adrienne rich
اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...
15 صفحه اولPatterning mechanisms controlling vertebrate limb development.
Vertebrate limb buds are embryonic structures for which much molecular and cellular data are known regarding the mechanisms that control pattern formation during development. Specialized regions of the developing limb bud, such as the zone of polarizing activity (ZPA), the apical ectodermal ridge (AER), and the non-ridge ectoderm, direct and coordinate the development of the limb bud along the ...
متن کاملPathways regulating apoptosis during patterning and development.
The patterning and development of multicellular organisms require a precisely controlled balance between cell proliferation, differentiation and death. The regulation of apoptosis is an important aspect to achieve this balance, by eliminating unnecessary or mis-specified cells which, otherwise, may have harmful effects on the whole organism. Apoptosis is also important for the morphogenetic pro...
متن کاملDevelopment: Morphogen gradients and mesodermal patterning
Activin has long-range effects in Xenopus development, inducing the mesodermally expressed brachyury gene up to 10 cell diameters from a localised source. Recent experiments show that activin diffuses through tissues to establish a morphogen gradient, and that the long-range effects are a direct result of activin signalling.
متن کاملLeft Right Patterning, Evolution and Cardiac Development
Many aspects of heart development are determined by the left right axis and as a result several congenital diseases have their origins in aberrant left-right patterning. Establishment of this axis occurs early in embryogenesis before formation of the linear heart tube yet impacts upon much later morphogenetic events. In this review I discuss the differing mechanisms by which left-right polarity...
