conclusions in this study, use of one miniplate or two miniplates for treatment of favorable mandibular angle fractures was associated with a similar incidence of complications. thus, it seems that the use of two miniplates in this setting may not be warranted, nor cost-efficient. results in the single miniplate group, 25 patients showed lip numbness associated with surgery (55.6%), 22 patients...

in this paper, the direct extrusion process of bimetallic rods in conical dies is analyzed by an improved upper bound method. the deformation zone is subdivided into six smaller zones and by considering a non-spherical entrance boundary to the deformation zone, a velocity field is presented which is different from velocity fields employed in previous studies. the total power consumption of the ...

transportation as a prerequisite and basics of stable development has a key role and great efficiency in seeding facilities and intellect. it has also a significant role as an effective index in growth and development to the extent that the number of accidents in our country are increasing which carries with them a lot of financial, psychological and social losses, for this reason, it seems to ...

in this paper, multi-stage optimum design of composite pressure vessels is presented. the design variables for composite vessels include the head shape, the winding angle, the layer thickness, the number of layers, and the stacking sequence. a parameter called modified shape factor is introduced as an objective function. this parameter takes into account the effects of the internal pressure and...

This publication shows the results of measurements of the noise level emitted by the motor trucks on the internal roads of the steelworks. The distribution of the metallurgical products with the use of trucks is, next to the rail transport, one of the main logistic forms of products delivery to the customer. The research was conducted on one of the busiest internal roads of metallurgical enterp...

BACKGROUND We aimed to search whether alpha angle, a radiological clue used in the diagnosis of femoroacetabular impingement, is correlated with the presence of hip pain, internal rotation angle, and impingement test results on hip impingement patients (CAM type). METHODS Medical records of 334 patients (156 women, 178 men) with an average age of 33.8 ± 8.4 (range 20-50) years were retrospect...

BACKGROUND The hand-behind-back method is the accepted technique to evaluate shoulder internal rotation, is highly popular, and is endorsed by the American Academy of Orthopaedic Surgeons. It remains, however, subject to intra- and interexaminer discrepancy and has been challenged by several recent publications. HYPOTHESIS Internal rotation behind the back can be evaluated with a measurable a...
