The hydrolysis of dentin and cementum glycosaminoglycans following fluoride immersion.
The roots of human premolar teeth were analyzed biochemically for total glycosaminoglycan after fluoride treatment and enzymatic digestion. Base levels of dentin and cement~Jm fluoride (780 +_ 105 ppm) and controls showed a statistically significant difference from the fluoride-treated teeth (1250 +__ 120, 1675 +_ 105, 2150 +_ 145 ppm) for the 1-, 8-, and 24-hour periods respectivel.v. The amou...
متن کاملFluoride uptake and retention at various stages of rat molar enamel development.
Suckling rat pups were given intraperitoneal fluoride injections at selected ages so that we could study fluoride uptake in the enamel of the maxillary first molar at various stages of enamel development. Plasma fluoride levels in six-day-old and 11-day-old pups were monitored following the intraperitoneal injection of fluoride. The findings indicate that: (1) fluoride was more easily taken up ...
متن کاملMeasurement of Fluoride Concentration in Semnan Drinking Water Distribution
Background: The existence of fluoride ion in potable water has distinctive effects on human health. Fluoride is attracted by positively charged calcium in teeth and bones due to its strong electro-negativity which results in dental, skeletal, and non-skeletal forms of xuorosis and associated health complaints in children as well as adults. Methods: Water samples from groundwater used for dri...

چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
