Pull-up and modified pull-up tests are frequently used for shoulder muscles endurance evaluation by physical educators. Despite of using these tests, the difference of muscle activation pattern in pull-up and modified pull-up tests has not been documented clearly. However, the role of some important muscles such as anterior deltoid, posterior deltoid, trapezius and latissimus dorsi have no...

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). Some investigators have also observed that this morbid ur...

A method for force-free control is proposed to realize pull-out work by an industrial articulated robot arm. This method achieves not only non-gravity and non-friction motion of an articulated robot arm according to an exerted force but also reflects no change in the structure of the servo controller. Ideal performance of a pull-out work by the force-free control method was assured by means of ...

We have examined the deterioration of implant fixation after withdrawal of parathyroid hormone (PTH) in rats. First, the pull-out force for stainless-steel screws in the proximal tibia was measured at different times after withdrawal. The stimulatory effect of PTH on fixation was lost after 16 days. We then studied whether bisphosphonates could block this withdrawal effect. Mechanical and histo...
