One practical excavation support system is the inclined struts connected to adjacent buildings. This method is very common in small excavations, because of simplicity and minimum cost, when soil is cohesive and depth of excavation is less than stability depth (Hcr) but adjacent structures is at risk of damage due to weakness, old age or lack of proper skeleton frame. Although this method ...

Neighborhoods within the hierarchy of urban structure are one of the smallest socio-physical building blocks of cities. Traditional neighborhoods of Iranian historic cities benefited from strong social relations which were flourished over the years and were manifested in the neighborhoods centers. In the modern era, the new master plans and the complementary local plans have disintegrated th...

UNLABELLED Multiple complications have been reported with spinal intervertebral transforaminal injection procedures, despite the use of fluoroscopic needle-positioning measures. We explored an imaging technology (optical coherence tomography, or OCT) for its possible use in spine interventional procedures as a means of providing needle tip vision at the neuroforamen. Optical coherence tomograph...

This study (1975-1977) examines the effect of man-made structures on natural sand bottom communities in shallow water in San Diego County, southern California, USA. While there were shallow scour effects to 15 m around some artificial reefs, the reefs had no measurable effect on sand ripple patterns, grain size, organic carbon or infauna beyond the scoured areas. Foraging by reef-associated fis...

ISP fixation has been shown to be a safe and efficacious alternative to traditional methods of posterior spinal fixation. A high degree of biomechanical stability and reliable fusion rates are achieved with preservation of adjacent level structures when using new iterations of rigid interspinous fixation. Since ISP devices do not violate adjacent facet joints, they potentially can decrease the ...

al site of distant metastasis or direct invasion by malignant tumors of adjacent organs (1). Computed tomography (CT) and magnetic resonance imaging (MRI) findings, therefore, have not been described sufficiently of direct invasion of the spleen (2-5). For better understanding the route of direct invasion, it is prerequisite to emphasize the anatomic relation of the spleen with adjacent structu...

Abstract. Strong seismic excitations can induce considerable displacements in base-isolated structures. These may turn cause damage to the isolation system or impacts against adjacent structures event of an insufficient gap. A strategy reducing be achieved through interposition, between isolated structure and structures, deformable dissipative devices, called bumpers. In this paper, response si...

OBJECTIVE Although several clinical applications of transpedicular screw fixation in the cervical spine have been documented recently, few anatomic studies concerning the cervical pedicle are available. This study was designed to evaluate the anatomy and adjacent neural relationships of the middle and lower cervical pedicle (C3-C7). The main objective is to provide accurate information for tran...

STATEMENT OF THE PROBLEM The sphenoid sinus is a common target of paranasal surgery. Functional endoscopic sinus surgery is likely to endanger the anatomic variations of vital structures adjacent to the sphenoid sinus. PURPOSE The aim of this study was to determine the variations of sphenoid sinus and the related structures by using cone-beam computed tomography (CBCT). MATERIALS AND METHOD...
