Separation of Pure 90Y from a 90Sr-90Y Mixture by Co-precipitation with Ferric Hydroxide, Using a Pyridine as a Precipitant

90Y ferric hydroxide colloid.

At the Radiochemical Centre we have recently developed a new 90Y colloid which has greater stability than the currently available 90Y silicate colloid and appears from the results of animal tests to be suitable for the treatment of rheumatoid knee joint effusions. In this report the need for a new 90Y colloid is assessed and the preparation and properties of the new colloid are described. Curre...

Comparison of 90Y ferric hydroxide colloid with the citrate and resin colloids. A preliminary animal study.

This was a preliminary evaluation of 90Y ferric hydroxide colloid for the Radiochemical Centre before using it in patients. Autoradiographs of rabbit knees, both inflamed and non-inflamed, showed that the material was evenly distributed in the synovium, and that there was no evidence of aggregation in vivo. Table I shows the retention of ferric hydroxide colloid in the knees of nine rabbits kil...

Rapid 90Sr/90Y determination in water samples using a sequential injection method

We have developed a semiautomatic procedure based on a sequential injection method for 90Sr/90Y determination that allows their radiochemical separation in about 30 min. The method has been tested using 90Sr/90Y solutions with activities lower than 12 Bq. The source is eluted in a pH = 6.5 medium through a MnO2-impregnated cotton filter, where 9OY is preconcentrated in preference by adsorption....

translating allusive devices:a survey of a portrait of the artist as a young man by james joyce

تلمیح یکی از عناصری است که تقریباً در همه ی متون ادبی یافت و باعث ایجاد شکاف های فرهنگی می شود. در این تحقیق به عنوان شکلی از بینامتنیت در ترجمه مورد توجه قرار می گیرد. تلاش شده است تا راهکارهای مترجمان برای ترجمه چهار نوع اسامی خاص و عبارات کلیدی تلمیحی (مذهبی، سیاسی، تاریخی و اسطوره ای) موجود در رمانِ چهره مرد هنرمند در جوانی به فارسی بررسی شود. این تحقیق مقایسه ای بر اساس راهکارهای ترجمه تلمیح...
