pulsed current plasma arc welding (pcpaw) is one of the most widely used welding processes in sheet metal manufacturing industry. in any fusion arc welding process, the weld bead geometry plays an important role in determining the mechanical properties of the weld and hence quality of the weld.  moreover, the geometry of weld bead involves several simultaneously multiple quality characteristics...

BACKGROUND In a variable proportion of maxillary sinuses alveolar antral artery is located close to the residual ridge, increasing the chances for haemorrhagic complications during sinus floor elevation procedures. MATERIAL AND METHODS Retrospective observational study of CBCT explorations performed for implant-treatment planning. The upper first molar area was selected for this study. The re...

Introduction: Tunnel field effect transistors (TFET) have gained interest recently owing to their potential in achieving sub-kT/q steep switching slope, thus promising low Vcc operation[1-5]. Steep switching slope has already been demonstrated in Silicon TFET [2]. However, it has been theoretically shown and experimentally proved that Si or SixGe1-x based homo-junction or hetero-junction TFETs ...

Complex traits often involve interactions between different genetic loci. This can lead to sign epistasis, whereby mutations that are individually deleterious or neutral combine to confer a fitness benefit. In order to acquire the beneficial genotype, an asexual population must cross a fitness valley or plateau by first acquiring the deleterious or neutral intermediates. Here, we present a comp...

PURPOSE The aim of this paper is to present a large-scale long-term follow-up of dental implants placed simultaneously with nasal floor augmentation using osteoconductive bovine bone substitutes. MATERIALS AND METHODS Patients who received dental implants combined with nasal floor elevation in three dental centers between 2006 and 2012 were included in this report. Preoperative available bone...

The purpose of this study was to evaluate dimensions of adult human maxillary sinuses on panoramic radiographs and their possible application on the sex determination for forensic purposes. The sample comprised 64 database panoramic radiographs from individuals aged 20 years or older (32 male and 32 female subjects), with complete permanent dentition (or absence of third molars). One examiner m...

The paper examines the effect of the solar chimney’s stack height, depth, width and inlet position on the interior performance (air temperature and speed at 1.20 m height above the ground) as well as proposes an optimal tropical solar chimney design. Simulations show that the output air temperature remains constant while the solar chimney’s width is the most significant factor influencing outpu...

The facial width-to-height ratio (fWHR) is a perceptual cue that affects the perception of psychological traits such as dominance. current research examined whether fWHR would impact dominance and emotional intensity when expressing emotions. In study one, we expressions (EFEs) modify visually perceivable by following specific pattern reflecting associated with basic EFEs. We found EFEs differe...

The zone of active eruptive fissuring (the “spreading axis”) is investigated at an accretionary segment of the Mid-Atlantic Ridge. High-resolution side-scan images are used to produce a detailed geologic map of the median valley floor of Segment 18, located immediately south of the Atlantis Transform (30oN). The spreading axis is defined by distinguishing between primary eruptive vents (seamoun...
