Water is conceivably the most important material in universe and essential to functioning of all known life-forms. A simple expression for real part refractive index water was investigated proposed a new equation as function temperature between 0 oC 100 also wavelength range 200 1100 nm. transparent visible light has complex optical absorption property infrared ultraviolet ranges. The highly de...

INTRODUCTION Soft denture liners have a key role in modern removable prosthodontics since they restore health to inflamed and abused mucosa by redistribution of forces transmitted to the edentulous ridges. The most common problems encountered using soft denture liners are water sorption and solubility when in contact with saliva or storage media. These problems are associated with swelling, dis...

A model experiment monitoring the fate of total residue oxidant (TRO) in water at a constant temperature and salinity indicated that it decayed exponentially with time, and with TRO decaying faster in seawater than in distilled water. The reduction of TRO by temperature ( degrees K) was found to fit a curvilinear relationship in distilled water (r(2) = 0.997) and a linear relationship in seawat...

Oxidative damage is involved in age-related inflammatory reactions. The anti-oxidative effects of hydrogen-rich water suppress oxidative damage, which may aid in inhibiting age-related inflammatory reactions. We investigated the effects of drinking hydrogen-rich water on aging periodontal tissues in healthy rats. Four-month-old male Fischer 344 rats (n = 12) were divided into two groups: the ex...

We investigated the emergence of third-stage larvae (L3) of Umingmakstrongylus pallikuukensis from the slugs Deroceras laeve, Deroceras reticulatum, and the snail Catinella sp. in the laboratory and from D. laeve on the tundra. Third-stage larvae emerged from 8 of 8 D. laeve and 8 of 8 D. reticulatum housed at 20 C in darkness and from 9 of 10 D. laeve and 5 of 5 Catinella sp. housed at 21 C wi...
