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 اولMyofibrillar gene expression in differentiating lobster claw muscles.
Lobster claw muscles undergo a process of fiber switching during development, where isomorphic muscles containing a mixture of both fast and slow fibers, become specialized into predominantly fast, or exclusively slow, muscles. Although this process has been described using histochemical methods, we lack an understanding of the shifts in gene expression that take place. In this study, we used s...
متن کاملAre muscles mechanically independent?
MOST PHYSIOLOGY TEXTS imply that the mechanism by which force is transmitted from sarcomeres to muscle insertions is simple: when skeletal muscles contract, cross-bridge forces are transmitted along myofibrils, through the sarcolemma and extracellular matrix to tendons and, ultimately, bones. At each level of organization, myofibrils, muscle fibers, and muscles behave as mechanically independen...
متن کاملMechanoreceptors and Minimal Reflex Activity Determining Claw Laterality in Developing Lobsters
Bilateral asymmetry of the paired claws of the lobster Homarus americanus is determined during the fourth and fifth juvenile stages by differential reflex activity; the side with the greater activity becomes the crusher while the contralateral side becomes the cutter. Juvenile lobsters reared during this critical period with a substratum that could not be grasped or with reduced input from pred...
متن کاملBilaterally Symmetrical Transformation between Independent Operators and Rotations
This report describes an approach for representation of quantum operators through rotations and rotation through quantum operators. The approach of the proposed method transforms rotation in a kind of a unitary matrix that corresponds to the rotation. Operations with qubits are very similar to the rotation, but with an added phase coefficient. This fact is used to create a process for rotation ...
