Aluminum-based coagulants in drinking water treatment are widely used across Canada. According to the literature, the presence of aluminum in drinking water poses possible risks to humans. Preliminary studies investigating the use of alternative coagulating agents such as iron-based coagulants, lanthanide salts and organic coagulants have already revealed that their implementation is possible, ...

Laser biostimulation has been found effective in treatment of wound healing and inflammatory conditions. The nature and characteristics of laser light is different from natural light and of conventional light sources. Specifics of the laser include spectral coherence, temporal coherence and spatial coherence [1,2]. In addition, some lasers emit polarized photons and parallel beam. Laser with th...

Comparison of mitotic indices obtained in tissues from intact control animals with those obtained in tissues from castrate control animals (Table I) indicates that orchidectomy results in a depression of mitotic activity in all cases. The T-test shows this drop to be significant in ear, coagulating gland and ventral prostate (PC 0.01) but not significant in the case of seminal vesicle (P = 0.4)...
