متن کاملUsing Stable Isotopes
Introduction Direct measurement of de novo lipogenesis has not previously been possible in humans. We measured de novo hepatic lipogenesis in normal men by means of stable isotopes and by combining the acetylated-xenobiotic probe technique with mass isotopomer analysis of secreted very low density lipoproteinfatty acids (VLDL-FA). Sulfamethoxazole (SMX) was administered with ['3Clacetate during...
متن کاملFish fins as non-lethal surrogates for muscle tissues in freshwater food web studies using stable isotopes.
RATIONALE Dorsal white muscle is the standard tissue analysed in fish trophic studies using stable isotope analyses. However, sampling white muscle often implies the sacrifice of fish. Thus, we examined whether the non-lethal sampling of fin tissue can substitute muscle sampling in food web studies. METHODS Analysing muscle and fin δ(15)N and δ(13)C values of 466 European freshwater fish (14 ...
متن کاملa swot analysis of the english program of a bilingual school in iran
با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...
15 صفحه اولInfluences of Windthrow in Forested Stream Buffers
Forestry operations have long been understood to contribute to non-point source pollution. With the implementation of federal regulations to thwart such pollution and protect water quality, North Carolina adopted rules called Forest Practice Guidelines (FPGs). This research assesses the efficacy of a specific FPG called Streamside Management Zones (SMZs) for the North Carolina Forest Service (N...
