Suture joints are remarkable mechanical structures found throughout nature composed of compliant interlocking seams connecting stiffer components. This study investigates the underlying mechanisms and the role of geometry governing the unique mechanical behavior of suture joints. Analytical and numerical composite models are formulated for two suture geometries characterized by a single repeati...

We describe three sisters in a family who presented with a clinical form of osteomesopycnosis which is a rare, benign osteosclerotic bone disorder limited to the axial skeleton. It must be distinguished from other osteosclerotic conditions which carry a worse prognosis. This is the first report of the condition in a Japanese family, and we believe it to be the first to be identified in Asian ra...

In the present work, the mathematical model of a homogeneous, isotropic thermoelastic double porous micro-beam, based on the Euler-Bernoulli theory is developed in the context of Lord-Shulman [1] theory of thermoelasticity. Laplace transform technique has been used to obtain the expressions for lateral deflection, axial stress, axial displacement, volume fraction field and temperature distribut...

original article   to determine the association between ocular biometric components and near work in bank employees.this study was conducted as an analytical cross-sectional study. a group of bank employees and a control group were randomly selected. after applying the inclusion criteria, all selected subjects had a set of examinations including refraction, uncorrected and corrected visual acui...

the drilling is well known as one of the most common hole making processes in the industry.due to close tolerance requirement for drilled holes in the most of work pieces, onlinecontrolling of the diameter of drilled holes seems to be necessary. in the current work, an onlinedimensional controlling system was developed for drilling process. doing this, drilling processwas executed in different ...

axial vibration effect of shell particles on dynamic stability of a cantilevered cylindrical shell under an axial follower force was addressed. in spite of free-ended shells, the reduced axial force under this effect cannot be derived analytically. instead, an approximate method was proposed based on the fact that the static (and harmonic) axial deformation under an axial load in a free-ended b...

total calcium with overt bone disease is hard to explain. The history of constipation, nocturia and polyuria, albeit mild, do suggest hypercalcaemia and it may be that the ionized calcium was elevated without the total calcium being raised. There are many points of similarity in the patient reported here with the case reported by Mather in 1953. His patient was a 39-year-old woman who had devel...
