This study included examined of the microbial and chemical content some physical properties bottled water manufacturers locally circulating in city Samarra markets. It was counting number colonies both bacteria fungi, measuring pH value electrical conductivity suspended solids total distress, bio-oxygen demand as well concentrations each calcium, sodium, magnesium, potassium, nitrates, iron, fl...

A selective medium (CFAT) was developed for the detection and enumeration of Actinomyces viscosus and Actinomyces naeslundii in dental plaque. Neutral acriflavin and potassium tellurite were used in combination with the known selective agents cadmium and fluoride to eliminate most of the competing plaque flora. Composition of CFAT per liter was as follows: Trypticase soy broth (BBL Microbiology...

Propolis and bee pollen are substances produced by honey bees its components are strong antioxidant and free radical scavengers. The present study aimed to study the protective effects of propolis and bee pollen supplementation against toxicity of sodium fluoride in rats. After the end of experimental period, the rats sacrified and biochemical analysis were carried out. The results showed that ...

The bound electronic nonlinear refractive index, n 2 • and two-photon absorption (2PA) coefficient, 6, are measured in a variety of inorganic dielectric solids at the four harmonics of the Nd:YAG laser using Z scan. The specific materials studied are: barium fluoride (BaF2 ), calcite (CaC03), potassium bromide (KBr), lithium fluoride (LiF), magnesium fluoride (MgFz), sapphire (Ab03), a tellurit...

Homogenates of six rat tissues metabolized the o-amidofluorenol, N-(1-hydroxy-~fluorenyl)aeetamide, as judged by the disappearanee of the phenolic hydroxyl group of the compound from the ineubation systems. By the same criterion, N-(7-hydroxy-~fluorenyl)aeetamide was resistant to metabolie attack. The deaeylation of N-(1-hydroxy-~-fluorenyl)aeetamide, N-(7-hydroxy-~-fluorenyl)aeetamide, N-s and...

The fluoride concentration in ground water was determined in ten villages of Rohtak district of Haryana state (India). The fluoride concentration in the underground water of these villages varied from 0.034-2.09 mg/l. Various other water quality parameters, viz., pH, electrical conductivity, total dissolved salts, total hardness, total alkalinity sodium, potassium, calcium, magnesium, carbonate...
