background: there are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. in the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. methods: forty patients with valgus knee malalignment were randomly assigned to two equal numb...

Tailor-made blanks are sheet metal assemblies with different thicknesses and/or materials and/or surface coatings. A monolithic sheet can be machined to make the required thickness variations that is referred as tailor machined blanks. Due to the thickness variation in tailor machined blanks, laser bending of these blanks is more complicated than monolithic plates. In this article, laser formin...

laser forming is a modern process which is mainly used for forming metals. different lasers are used in this regard that includes nd: yag and co2. in this study, forming bi-layer sheets of aluminum/ceramic by laser was investigated. furthermore, effect of uniform and gaussian heat flux distribution in different power, velocity, and beam diameters on bending angle was studied. fem simulation ind...

BACKGROUND A combination of frontal bending, lateral bending, and torsion in the loaded trunk has been suggested to be a mechanism leading to overuse injuries of the back in Alpine ski racing. However, there is limited knowledge about the effect of course setting on the aforementioned back-loading patterns. PURPOSE To investigate the effect of increased gate offset on the skier's overall trun...

The objective of this research is to develop neck injury criteria and injury tolerance levels to be used as a basis for a performance standard for the certification of side facing aircraft seats. This paper presents the results of the first part of this study. A literature review was performed on the neck injuries, kinematics and injury mechanisms in lateral loading and existing injury criteria...

objective(s) the objective of this study was to document and explain bilateral differences in the q angle. materials and methods two hundred limbs of healthy adult indian volunteers were studied. the q angle was measured using a goniometric method with the subjects supine, quadriceps relaxed and lower limbs in neutral rotation. the relative lateral placement of the tibial tuberosity with respec...

In this study, the effects of heat treatment of aluminum alloy on the tube bending process were investigated in the rotary draw bending process. As two experimental and numerical simulation methods were used to determine the wall-thinning, ovality, and spring back for extruded, annealed, and aged AA6063 aluminum alloy tubes in different bending angles and bend radii. Numerical simulations were ...

In this paper we consider the onset of shimmy oscillations of an aircraft nose landing gear. To this end we develop and study a mathematical model with torsional and lateral bending modes that are coupled through a wheel-mounted elastic tyre. The geometric effects of a positive rake angle are fully incorporated into the resulting five-dimensional ordinary differential equation model. A bifurcat...
