Geosynthetic reinforced soil (GRS) walls and abutments are increasingly used to support transportation infrastructure. A pressing question in their response is the amount of horizontal deflection expected under service loads. This paper presents an evaluation of six methods for predicting the lateral deformation of GRS walls and abutments, namely the FHWA, Geoservice, CTI, Jewell-Milligan, Wu, ...

composite concrete-steel plate shear walls are the most critical resisting structural members that resist lateral and axial loads. This type of wall consisting of two steel faceplates presenting the outer skin, infill concrete and shear connectors which are used to provide the composite action of the steel faceplates with infill concrete in order to increase the strength and to reduce the local...

background and objective: numerous anatomical abnormalities or pathological conditions can cause upper airway obstruction in obstructive sleep apnea syndrome (osas). muller’s maneuver (mm) is one of diagnostic modalities investigating the obstruction site in patients with osas. this study aimed to investigate the obstruction sites of patients with osas based on mm. materials and methods: this w...

OBJECTIVES/HYPOTHESIS To evaluate sites and characteristics of upper airway obstruction, as detected with drug-induced sleep endoscopy (DISE) in children with obstructive sleep apnea (OSA). MATERIAL AND METHODS The medical records of children who underwent DISE were reviewed. Data pertaining to demographics, past medical history, body mass index, tonsil size, adenoid size, polysomnography, an...

Granular materials have a tendency to exhibit an arching effect by which the load is transferred from yielding parts to adjacent stationary parts. Retaining walls are among those structures that the soil arching plays an important role in the distribution of earth pressures. This paper briefly reviews the development of soil arching theory and its application to different geotechnical projects....

eart pressure problems are encountered in retaining walls, bulkheads, sheeting and bracing in cuts,culverts, tunnels, and cofferdams. in many cases, the lateral pressure is determined by use of classical earth pressure theories, such as coulomb's, where the equilibrium conditions of a failure wedge of soil is considered. excessive dynamic lateral earth pressure on retaining structures resu...

We examined 27 resin casts of foetal liver veins and found three types of connection between portal vein and portal sinus. The most frequent connection was endo-lateral (66.7%), when the end of the portal vein joins with the lateral wall of the portal sinus. The next type was latero-lateral (14.8%). In this type, the lateral walls of the portal sinus and the portal vein join together. The last ...

White and Brown (1939) found the following distribution in 1,062 cases : uncomplicated lateral deviation in 347 patients, uncomplicated vertical deviation in 358, and combined vertical and lateral deviation in 357. Dunnington and Regan (1950) found that 50 per cent. of 79 cases of concomitant convergent strabismus showed a vertical component. Scobee (1951), in 457 cases of convergent strabismus...
