The vertical facial proportions resulting from bimaxillary surgery (maxillary advancement and mandibular setback) and mandibular setback alone were evaluated. The measurements were evaluated on the preoperative and postoperative cephalometric radiographs of 20 skeletal Class III patients. The results showed that sagittal correction of the jaws caused no change in the vertical relationship of th...

Continuous and simultaneous observational particulate matter (measured as PM10), nitrogen dioxide (NO2) and oxides of nitrogen (NOx) data were captured at a kerbside site alongside a major highway in Auckland, New Zealand, and at a pair of setback sites within 250 m of the highway, day and night over 8 weeks. The three measurement sites were intended to allow emissions from the highway to be la...

DC transfer characteristic measurements have been carried out on one n-channel Si/SiGe MODFETs with a MOS gate at three different substrate biases. For our layer structure, electrons are supplied into the strained Si quantum well (QW) from the top heavily doped layer and below the QW is non-intentionally doped (setback). Here, we numerically studied the setback layer, for which the doping can b...

BACKGROUND The posterior movement of mandible was known as the main cause of the changes in the pharyngeal airway space (PAS) and the postoperative obstructive sleep apnea (OSA). The purpose of this study was to know the changes of PAS and position of hyoid bone. METHODS Lateral cephalographies of 13 patients who had undergone sagittal split ramus osteotomy (SSRO) setback surgery were taken p...

setback in elevation of a structure is a special irregularity with considerable effect on its seismic performance. this paper addresses multistory reinforced concrete (rc) frame buildings, regular and irregular in elevation. several multistory reinforced concrete moment resisting frames (rcmrfs) with different types of setbacks, as well as the regular frames in elevation, are designed according...

PURPOSE The purpose of this systematic review was to evaluate relapse and its causes in bilateral sagittal split setback osteotomy with rigid internal fixation. MATERIALS AND METHODS Literature research was done in databases such as PubMed, Ovid, the Cochrane Library, and Google Scholar Beta. From the original 488 articles identified, 14 articles were finally included. Only 5 studies were pro...

The use of atmospheric dispersion modelling has become more common for the determination of odour impacts from existing poultry production facilities and the assessment of setback distances for new facilities. Setback distances for broiler, layer and turkey units were determined using the atmospheric dispersion modelling software ISCST3 and the Environmental Protection Agency (EPA, Ireland) rec...
