Stent insertion for cerebral aneurysm has been studied using ideal and realistic aneurysms in recent years. Stent insertion aims at reducing the flow in an aneurysm. To minimize the average velocity in an aneurysm, we applied optimization to the strut position in a realistic aneurysm based on computational fluid dynamics. The result shows the effect on velocity reduction of strut placement in t...

OBJECTIVES To introduce the cutting and suture technique of the caudal L-strut for the management of caudal septal deviation and to evaluate its efficacy and surgical outcomes. DESIGN Retrospective study. SETTING Tertiary care rhinology clinic. PATIENTS Forty-five patients who underwent endonasal septoplasty using the cutting and suture technique of the caudal L-strut. INTERVENTIONS Aft...

BACKGROUND The objective of this paper was to describe a novel technique for improving the maintenance of nipple projection in primary nipple reconstruction by using acellular dermal matrix as a strut in one of three different configurations, according to the method of prior breast reconstruction. The struts were designed to best fill the different types of dead spaces in nipple reconstruction ...

limitations in the design method used for the support systems of urban buildings make them vulnerable to damage by adjacent excavations. this paper examines a traditional system used to support excavation sites and adjacent buildings in which inclined struts are connected to the wall or foundation of the adjacent building. this method can be considered to be a type of shoring or underpinning. t...

Almost all species of modern birds are capable of flight; the mechanical competency of their wings and the rigidity of their skeletal system evolved to enable this outstanding feat. One of the most interesting examples of structural adaptation in birds is the internal structure of their wing bones. In flying birds, bones need to be sufficiently strong and stiff to withstand forces during takeof...

AIM Our aim was to evaluate the safety and efficacy of the novel crescent-shaped PMMA strut for anterior spinal reconstruction and fusion in patients with thoracolumbar bust fractures. The surgical results using this technique are reviewed. MATERIAL AND METHODS Six patients suffering thoracolumbar and lumbar fracture using a crescent-shaped PMMA strut combined with fixation for reconstruction...

UNLABELLED OBJECTIVES; We sought to evaluate whether strut thickness may impact the restenosis rate after stent implantation in small coronary arteries. BACKGROUND Small vessel size (<3.0 mm) is an independent risk factor for the occurrence of in-stent restenosis. It has been reported that vessel damage induced during stent deployment is an important factor in restenosis. METHODS From our d...

This paper chronicles the research on the design, analysis, experimentation and application of a high efficient, low-power variable stiffness suspension system. The central concept is based on a recently designed variable stiffness mechanism which consists of a horizontal control strut and a vertical strut. The horizontal strut is used to vary the load transfer ratio by controlling the location...

The contractile behavior of cells is relevant in understanding wound healing and scar formation. In tissue engineering, inhibition of the cell contractile response is critical for the regeneration of physiologically normal tissue rather than scar tissue. Previous studies have measured the contractile response of cells in a variety of conditions (e.g. on two-dimensional solid substrates, on free...

PURPOSE To review the outcomes of fixation with cancellous screws and fibular strut grafts for neglected femoral neck fractures. METHODS 44 men and 28 women aged 17 to 50 years with neglected femoral neck fractures of the subcapital (n=12), transcervical (n=57), or basal (n=3) types underwent closed (n=39) or open (n=33) reduction and fixation with a single cancellous screw with double fibula...
