A novel chemical detergent/disinfectant formulated based on persulfate salts, germicide P , is available for disinfection of surfaces and medical devices at the room temperature. Because of the resistance of hospital-resident microorganisms, the antimicrobial activity of this compound is evaluated in the present study. The tests conducted with this disinfectant included bactericidal tests ...

In this study, we give the relationships between the conical curvatures of ruled surfaces generated by the unit vectors of the ruling, central normal and central tangent of a ruled surface in the Euclidean 3-space E^3. We obtain differential equations characterizing slant ruled surfaces and if the reference ruled surface is a slant ruled surface, we give the conditions for the surfaces generate...

background recent evidences have revealed that in more than 65% of microbial infections, biofilms have critical roles. the ability of yeasts to form biofilms on surface of medical devices such as urine catheters is an important reason of the capability of these microorganisms to cause human disease. objectives the aim of this study was to isolate and identify yeasts on the surfaces of urine cat...
