the underlying structure of language proficiency and the proficiency level
هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولBeta-Lactam Antibiotics Induce a Lethal Malfunctioning of the Bacterial Cell Wall Synthesis Machinery
Penicillin and related beta-lactams comprise one of our oldest and most widely used antibiotic therapies. These drugs have long been known to target enzymes called penicillin-binding proteins (PBPs) that build the bacterial cell wall. Investigating the downstream consequences of target inhibition and how they contribute to the lethal action of these important drugs, we demonstrate that beta-lac...
متن کاملStructure, Function and Cell Biology of the Antigen- Processing Machinery
The adaptive immune system has evolved in vertebrates to eliminate invasive pathogens and malignantly transformed cells. Proteins are degraded in the cytoplasm by the proteasome. Subsequently, the peptides are transported from the cytoplasm into the lumen of the endoplasmic reticulum (ER) by the transporter associated with antigen processing (TAP) where they are loaded on MHC class I molecules....
متن کاملThe structure and synthesis of the fungal cell wall.
The fungal cell wall is a dynamic structure that protects the cell from changes in osmotic pressure and other environmental stresses, while allowing the fungal cell to interact with its environment. The structure and biosynthesis of a fungal cell wall is unique to the fungi, and is therefore an excellent target for the development of anti-fungal drugs. The structure of the fungal cell wall and ...
متن کاملBacterial cell wall synthesis: the effect of threonine depletion.
Our previous studies of Streptococcus faecalis 9790 have shown that the depletion of an essential amino acid from a highly buffered synthetic medium corresponds to the end of the exponential growth phase (log phase) (2, 3). The end of the log phase is followed by further turbidity changes that are characteristic for the particular amino acid studied. The exhaustion of valine is followed by a sl...
