Dental care is an essential phenomenon in human health. Oral pathogens can cause severe break which may show the way to serious issues in human disease like blood circulation and coronary disease. In the current study, we demonstrated the synthesis and antimicrobial activity of cadmium sulphide and zinc sulphide nanoparticles against oral pathogens. The process for the synthesis of cadmium sulp...

Purcell Mountains as a roadless tract of recreational wilderness area. It is located in the rugged mountain range between Kootenay Lake and the Columbia Valley, centred approximately 30 kilometres north of Kimberly (Figure 1-3-1) and is adjoined on the south by St. Mary's Alpine Provincial Park. Resource development, including mineral exploration and mining, was prohibited and any existing clai...

The goal of this project is to trace into central northern B.C. stratigraphy known to host Mississippian volcanogenic massive sulphide deposits such as Kudz Ze Kayah, Wolverine, and Fyre Lake, which lie within the Yukon Tanana Terrane in the Finlayson Lake belt of central Yukon. It is part of the Jennings River/Wolf Lake component of the Ancient Pacific Margin NATMAP project, a cooperative effo...

when organic material is decomposed under oxygen-limiting conditions (Nedwell, 1982). (The term sulphide is intended to include undissociated H2S, the bisulphide anion HS− and the sulphide anion S2−.) In marine sediments, sulphide production is enhanced by bacterial sulphate reduction (Jorgensen and Fenchel, 1974; Nedwell, 1982). Species inhabiting intertidal flats or salt marshes are, therefor...
