Fixation of the glenoid component is critical to the outcome of total shoulder arthroplasty. In an in vitro study, we analysed the effect of surface design and thickness of the cement mantle on the pull-out strength of the polyethylene pegs which are considered essential for fixation of cemented glenoid components. The macrostructure and surface of the pegs and the thickness of the cement mantl...

The use of near-surface mounted (NSM) fibre-reinforced polymer (FRP) bars is an interesting method for increasing the shear and flexural strength of existing timber members. This article examines the behaviour of carbon FRP (CFRP) bars in timber under direct pull-out conditions. The objective of this experimental program is to investigate the bond strength between composite bars and timber: bar...

Trichotillomania is an irresistible urge to pull out one's hair and this indulgence into actual pulling leading to baldness frequently. It is not yet established as a disease entity separately and usually considered as a manifestation of emotional disturbance (Monroe and Abse 1963) and disturbed interpersonal relationships (Tiling 1975).
