While the Lapidus procedure is a widely accepted technique for treatment of hallux valgus, the optimal fixation method to maintain joint stability remains controversial. The purpose of this study is to evaluate the biomechanical properties of new shape memory alloy (SMA) staples arranged in different configurations in a repeatable first tarsometatarsal arthrodesis model. Ten sawbones models of ...

In this study, composite materials are produced, placing unidirectional carbon fiber reinforcements with 12 filament numbers in a polyester matrix to form one, two, and three layers at room temperature through the hand lay-up method. The samples prepared from plates help of mold line direction angle by standards. tensile, three-point bending, falling weight low-speed impact strength values were...

In the present work, structure health monitoring (SHM) of welded steel pipes was used to diagnosis their state via vibration based damage detection techniques. The dynamic quantities such as Frequency Response Functions (FRFs), mode shapes and modal parameters from structural vibration to detect damage were measured, set on linear averaging mode, with a maximum frequency of analysis of 3.2 kHz....

The increase of patients with osteoporosis is a social problem. Osteoporosis decreases bone strength and increases the risk of fracture. The finding of prevention and treatment methods is an urgent issue. Since cancellous bone is metabolically more active than cortical bone, cancellous bone is used for diagnosis of osteoporosis. There are a lot of studies about stress analysis of cancellous bon...

in this study, the microstructure and properties of foam glass obtained as a result of the interaction of the waste glass with sic as the foaming agent and fe2o3 as the oxidizing agent have been investigated using scanning electron microscopy (sem), as well as three-point bending and pycnometery tests. first, the temperature and optimized amount of sic for making foam glass was determined. the ...
