Dental ceramic implants have shown superior esthetic behavior and the absence of induced allergic disorders when compared to titanium implants. Zirconia may become a potential candidate to be used as an alternative to titanium dental implants if surface modifications are introduced. In this work, bioactive micropatterned silica coatings were produced on zirconia substrates, using a combined met...

THE purpose of this paper is mainly to describe swan-necked grooved forceps which have been constantly in use for about 6 years in suturing cataract sections, corneal grafts, corneal wounds, scleral flaps, and also mucosal flaps in dacryocystorhinostomy. Angled, blocked suture-tying forceps are also described and illustrated. Fig. 1 shows the general pattern of the forceps. The handles are thos...

The authors report two cases with distension of the obturator internus bursa identified on MR images, and describe the location and characteristic features of obturator internus bursitis; the "boomerang"-shaped fluid distension between the obturator internus tendon and the posterior grooved surface of the ischium.

conclusions there was a decrease in cognitive function, including attention, visual memory, naming, and executive function, as well as psychomotor function among residents of department of anesthesiology and intensive care, faculty of medicine, universitas indonesia, who underwent 12 working hours. results cognitive stimulation” test revealed statistically significant decrease at sequential ima...

objective the purpose of this study was to assess the frequency of complications of endotracheal intubation (eti) in neonates. methods the newborns that were admitted and needed urgent or semi-urgent intubation were enrolled in this study over a 1 year period. route for intubation in all cases were orotracheal. cases were not routinely sedated or paralyzed. the patients were clinically and radi...

background and purpose: inserting a nasogastric tube, though a common clinical procedure with widespread use for critically ill patients, can produce unexpected complications so that tube misplacement into the lungs is a potential complication with serious consequences. the reliability of common bedside methods to differentiate between pulmonary and gastric placement has not been acceptable. th...

The surface morphology of micro- and nano- scale fiber determines its application to a great extent. At present, variety secondary microfibers nanofibers, such as porous, wrinkle, groove so on, have been prepared. Among them, grooved fibers are attracting more attention because their unique properties. In this paper, we review the literature on due void-based elongation, wrinkle-based collapsed...

The present experimental work is performed to investigate the convection heat transfer (HT), pressure drop (PD), irreversibility, exergy efficiency and thermal performance for turbulent flow inside a uniformly heated circular channel fitted with novel geometry of hybrid tape. Air taken as working fluid Reynolds number varied from 10,000 80,000. Hybrid tape made up combination grooved spring wav...
