This study aims to validate the accuracy of a cervical traction therapy simulation model by comparing the intervertebral separations of six asymptomatic male adults when traction was applied to their cervical spines. The subjects were tested on two mechanical traction devices, representing the inclined and sitting positions. A total of 55 radiographic images of their cervical spines were taken ...

We investigate the motion of a liquid drop as it flows along the interface of a liquid film. Steady, two-dimensional solutions are found in the lubrication limit for a horizontal and inclined plane. The effects of the physical parameters on the interface shapes are studied. When the plane is inclined, solutions are found only for a special set of parameter values.

In the title salt, C17H19N4 (+)·PF6 (-), the two pyridine rings of the cation are inclined to one another by 15.89 (8)°, and inclined to the imidazole ring by 65.05 (10) and 64.07 (10)°. In the crystal, the cations and anions are linked via a series of C-H⋯N and C-H⋯F hydrogen bonds, forming two-dimensional networks lying parallel to (001).

. 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...

A 57-year-old man presented with mesial inclination of the lower right first molar caused by untreated loss of the second premolar. The occlusal relationship was restored by dental implant treatment following improvement of the intraoral environment by orthodontic therapy. At his initial visit, the interdental spacing in the molar-premolar region was inadequate, as the first molar had mesially ...

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...
