Poly(methyl methacrylate) (PMMA) is used to fill the gap between the prosthesis and the surrounding bone in cemented arthroplasties. Biocompatibility problems related to bone cement application limit the clinical success of these cemented arthroplasties. Being the cement surface in close connection with the living bone, it is reasonable to assume that surface properties such as, surface composi...

KING, RICHARD J., AND JOHN A. CLEMENTS. Surface actiue materials from dog lung. 11. Composition and physiological correlations. Am. J. Physiol. 223(3) : 715726. 1972.-We studied the chemical composition and physical properties of the four surface active materials obtained from dog lung. All were composed of lipid and protein and contained less than 2y0 hexose and hexosamine. The four fractions ...

Settlement panels were used to evaluate the effects of composition of the substratum (sandstone, concrete, wood) and orientation (vertical, horizontal undersides) on subtidal epibiota. It was predicted that both factors would influence the development of epibiotic assemblages, but that differences due to composition would be less marked on horizontal undersides compared to vertical panels. Diff...

skid resistance and road condition are common indices of road safety; therefore providing adequate skidding resistance will reduce the incidence of road accidents. the surface macrotexture has a large effect on the characteristics of road surface skidding, which is the focus of this research. during the study, the mean texture depth of the road surface was measured, in order to determine the co...

Composition polysiloxane based coatings are currently the only viable commercial alternative of the toxic biocide containing antifouling paints. Oil incorporation improves the foul-releasing ability of the polysiloxane coatings. The impact of non-reactive, different molecular mass, both siloxane and fluorinated oil on the biofilm formation onto developed by us polysiloxane composition coating i...
