. AbstrAct The purpose of this clinical trial was to study the influence of platform-switching concept on crestal bone changes at non-submerged straight and inclined implants retaining mandibular overdentures. Eight patients received 2 implants one straight and the other inclined in the canine region of the mandible. Mandibular overdentures were retained using spheroflex abutment attachments, w...

Two‐wheeled mobile robots (TWMRs) have a capability of avoiding the tip‐over problem on inclined terrain by adjusting the centre of mass position of the robot body. The effects of terrain inclination on the robot performance are studied to exploit this capability. Prior to the real‐time implementation of position control, an estimation of the stability region ...

In the title compound, C16H10N2S2, the thienyl rings are inclined to one another by 62.71 (10)°, and are inclined by 63.94 (8) and 21.35 (8)° to the quinoline mean plane [maximum deviation = 0.031 (2) Å]. In the crystal, the mol-ecules pack in a herringbone pattern, with π-π stacking inter-actions [centroid-centroid distances = 3.7381 (15) and 3.7268 (15) Å].

inclined retaining walls with slopes less than perpendicular are appropriate candidates in several engineering problems. yet, to the knowledge of authors, only a few analytical solution for calculation of active earth pressure on such walls, which will be usually smaller than the same pressure on vertical ones, has been presented neither in research papers nor in design codes. considering limit...

abstract lateral intake is a hydraulic structure which is used for diversion of some portion of water from a river for the purpose of irrigation, storage and industrial. most of lateral intakes from canal are installed at canal with inclined banks which has not received the attention of the researchers in the past. since the flow discharge and sediment which enters the intake canal depends on t...

BACKGROUND The estimation of the distance from the skin to the thoracic epidural space or skin to epidural depth (SED) may increase the success rate and decrease the incidence of complications during placement of a thoracic epidural catheter. Magnetic resonance imaging (MRI) is the most comprehensive imaging modality of the spine, allowing for the accurate determination of tissue spaces and dis...

in this paper, free convection in an inclined stepped chamber has been studied. one wall of this enclosure is kept cold and the opposite wall equipped with constant heat source. the remaining walls are maintained adiabatic. there is one adiabatic step on the bottom wall. the aim of the present study is to forecast the effect of raleigh number, slope of enclosure, step dimension, and heat source...

OBJECTIVE To review my experience in both malar reduction and mandibular reshaping techniques to establish optional, effective, and reliable surgical procedures. A square-shaped face is considered aesthetically unfavorable among East Asians; therefore, reduction malarplasty and mandibular reshaping are becoming more acceptable for aesthetic facial skeleton recontouring. METHODS The techniques...

BACKGROUND The implications of self-medication practices are increasingly recognized around the world; however, little has been reported on the extent of self-medication practiced in Palestine. OBJECTIVE To determine the reasons, extent, and correlates of self-medication practices among university students in Palestine. METHODS A self-administered questionnaire eliciting self-medication pra...

normal axial alignment restoration in lower extremities is crucial for surgeons performing reconstructive surgeries. since reference normal values of axial alignment are affected by age, sex, and ethical issues, we tried to scrutinize these parameters in iranian adults and compare them with normal values in literatures. through a cross-sectional design, standing axial alignment views of lower e...
