A finite element based method is presented for evaluation of linearized dynamic equations of flexible mechanisms about a nominal trajectory. The coefficient matrices of the linearized equations of motion are evaluated as explicit analytical expressions involving mixed sets of generalized co-ordinates of the mechanism with rigid links and deformation mode co-ordinates that characterize deformati...

BACKGROUND Ipsilateral femoral neck and shaft fractures are rare, and currently available treatment methods each have their own benefits and limitations. Although reconstruction intramedullary nails have been considered to be effective alternative, clinical outcomes vary significantly in reports. METHODS Thirty-seven consecutive adult patients with 37 combined fractures were treated with reco...

Hair dysplasias are congenital or acquired alterations which often involve the hair shaft. Hair shaft abnormalities are characterized by changes in color, density, length and structure. Hair shaft alterations often result from structural changes within the hair fibers and cuticles which may lead to brittle and uncombable hair. The hair of patients with hair shaft diseases feels dry and looks lu...

The stomatostylet of Criconemoides curvature consists of three parts: tooth cone, shaft, and knobs. The tooth cone constitutes the outer conical covering and inner lining of the anterior half of the stylet lumen. The tooth cone is easily separated from the shaft by treating an isolated styler with 0.5% sodium hypochlorite. The posterior half of the shaft is cylindrical, tapering anteriorly to f...

background femur fracture is one of the most common fractures in children. certain parameters such as the patient’s age, the exact location of fracture, type of fracture, the mechanism of fracture, and the accompanying injuries determine which one of the many treatment techniques be used in each case. objectives we aimed to compare the results of close and open techniques in pediatric femoral s...
