‏‎comprehension monitoring in l1&l2‎‏

هدف اصلی این تحقیق مقایسه و تمایز بین روشها و استراتژیهای خاص برای درک مطلب بهتر در زبان مادری و زبان دوم بوده است. در قدم اول میزان توانایی افراد در درک مطلب فارسی و انگلیسی اندازه گیری و سپس رده بندی شد. همچنین از دانش آموزان خواسته شد که در مورد روشها و استراتژیهایی که برای درک مطلب بهتر به کار برده بودند توضیح دهند. نتیجه این مرحله از تحقیق نشان داد که دانشجویان برای درک مطلب مطلوب در زبان ...

BIOLOGICAL MONITORING OF MERCURY EXPOSURE IN DENTISTS OF TEHRAN

In order to assess the risk for mercury poisoning in dentists, urine specimens were collected and analysed from 250 dentists (190 male, 60 female). Subject data and pertinent health symptoms were asked via a questionnaire. The results indicate that the mean and standard deviation of mercury values were 51.3± 38.0 µg/L, while 27.2 percent of dentists had levels within normal limits (0-19 µg/...

Immunochemical techniques in biological monitoring.

Immunoassays are analytical methods that detect interactions between antibodies and antigens. Immunoassays were used originally to detect large biological molecules. The new generation of these antibody-based assays can detect small synthetic compounds. As a result, immunoassays are being developed specifically for biomarkers of exposure and effect to environmentally prevalent chemicals. Immuno...

Hypogenic Caves in the UK

The UK has a wide variety of hypogenic caves, including transverse maze caves, relict hydrothermal caves, gypsum mazes and hypogenic karst associated with water rising up deep thrust faults. While few of these are particularly extensive, they offer insights into the mechanisms of speleogenesis and mineralisation. The best developed hypogenic caves in the UK are in the Carboniferous limestones o...
