With the aim of introducing laser-arc hybrid welding (LAHW) into field large steel shipbuilding, a study was carried out to construct T-shaped fully penetrating welded joint with weld length 3,000 mm in one pass. Tack for installation members, which is preliminary step LAHW, by CO2 gas shielded arc welding. Since effect main LAHW on tack has not been sufficiently confirmed, investigations were ...

Ellipsoid and toroid-shaped articulations for total wrist prostheses were evaluated using computer modeling and laboratory experiments. An ellipsoidal design was found to accommodate greater width of the concave proximal component, resulting in better capture and prosthetic stability than a toroid shape. An ellipsoid articulation also provides greater contact area through the available arc of m...

Abstract Satellite images frequently show mesoscale arc-shaped cloud lines with a spacing of several tens kilometers. These clouds form in shallow mixed boundary layer locations where the near-surface horizontal wind speed exceeds ~7 m s −1 . Unlike other line phenomena, such as convective rolls, these do not align direction but at large oblique angles to wind. A particularly distinct event thi...

BACKGROUND The suprascapular notch (SSN), bridged by the superior transverse scapular ligament (STSL), creates a pathway for the suprascapular nerve (SN). Morphological variations in the SSN region are common and can increase the risk of neuropathy by constricting the space for the nerve. The aim of this study was to establish new objective parameters that take this complex morphology into acco...

INTRODUCTION Constuction of the obturator prostheses and providing the patient's comfort with them are very difficult. Primary and the most important stage for these prostheses is to perform a proper impression. CASE PRESENTATION A 55-year-old edentulous Turkish female patient with a congenitally maxillary defect was rehabilitated with an open hollow obturator prosthesis. After the preliminar...
