مطالعه حاضر تلاشی است برای بررسی تأثیرات به کارگیری فرهنگ لغات ، یکی از مهمترین ابزارهای یادگیری واژگان درفراگیری زبان خارجی، بر روی دانش لغوی. دراین تحقیق فرهنگ های الکترونیکی در قیاس با فرهنگ های چاپی مورد بررسی قرارگرفته اند که آیا این فرهنگ ها تاثیرقابل توجهی بر روی دوبعد کمی و کیفی دانش لغوی یعنی عمق و گستره لغات می گذارند. همچنین مشخص گردیده است که آیا تفاوت قابل ملاحظه ای میان عمق و گستر...
15 صفحه اولCarbohydrate utilization in the pre-ruminant calf.
3. Maltose and fructose utilization was low in young calves and increased slightly with age. 4. Sucrose and starch were not utilized. 5. Studies with three older pre-ruminant calves (aged 53, 88 and 106 days) in which the carbohydrates were infused into the proximal duodenum showed that glucose, galactose, lactose and xylose all caused marked increases in the level of blood reducing sugar, wher...
متن کاملMetabolic Rate, Blood Sugar and the Utilization of Carbohydrate
The many observations on blood sugar in exercise have revealed widely different conditions. Thus one may have extreme hypoglycemia as found by Levine, Burgess and Derick (1) in some marathon runners, or at the other extreme, hyperglycemia as in football players (2). A moderate decrease in the concentration of sugar in the blood (B. S.) has been found by Christiansen (3) in exercise of one hour’...
متن کاملRapid carbohydrate utilization test for the identification of Neisseria gonorrhoeae.
A rapid carbohydrate utilization test for the identification of N. gonorrhoeae was investigated, with reference to its use in a routine diagnostic laboratory. The rapid test was shown to give accurate results in agreement with those of a conventional serum-free sugar medium. Because of the shorter time taken for the confirmation of an isolate, and several other advantages, it is proposed that t...
متن کاملThe genetic analysis of carbohydrate utilization in Aspergillus nidulans.

The mutants were detected by their inability to utilize specific carbohydrates as sole carbon source for growth. All of the mutants are recessive and analysis of 27 mutants has resulted in the description of 10 new loci concerned with the utilization of carbohydrates in the organ...
