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 اولRegulation of ovule development.
Ovule development in Arabidopsis and other plants has been the focus of classic and molecular genetic analyses in recent years. This has been an exciting time to be involved in plant developmental biology, because many genetic pathways and regulatory mechanisms have been elucidated. Continued studies of ovule mutants have contributed to and benefited from these advances. Ovule development invol...
متن کاملPolarity Determinants in Dendritic Spine Development and Plasticity.
The asymmetric distribution of various proteins and RNAs is essential for all stages of animal development, and establishment and maintenance of this cellular polarity are regulated by a group of conserved polarity determinants. Studies over the last 10 years highlight important functions for polarity proteins, including apical-basal polarity and planar cell polarity regulators, in dendritic sp...
متن کاملDynamic Roles for Small RNAs and DNA Methylation during Ovule and Fiber Development in Allotetraploid Cotton
DNA methylation is essential for plant and animal development. In plants, methylation occurs at CG, CHG, and CHH (H = A, C or T) sites via distinct pathways. Cotton is an allotetraploid consisting of two progenitor genomes. Each cotton fiber is a rapidly-elongating cell derived from the ovule epidermis, but the molecular basis for this developmental transition is unknown. Here we analyzed methy...
متن کاملDeterminants of kinesin motor polarity.
The kinesin motor protein family members move along microtubules with characteristic polarity. Chimeric motors containing the stalk and neck of the minus-end-directed motor, Ncd, fused to the motor domain of plus-end-directed kinesin were analyzed. The Ncd stalk and neck reversed kinesin motor polarity, but mutation of the Ncd neck reverted the chimeric motor to plus-end movement. Thus, residue...
