The search for materials that can replace tin-doped indium oxide (ITO) as the leading transparent conductive electrode (TCE) has intensified significantly in the past few years, motivated by the ever-increasing price of indium. Materials such as carbon nanotube (CNT) films, graphene films, metal nanowire gratings, and random networks have been at the(More)
PURPOSE The present study evaluated the effect of smoking on achieving initial osseointegration when surface-modified dental implants were used. MATERIALS AND METHODS During an 18-month period in a private practice setting 1,183 implants were placed in 461 patients. The group of smokers consisted of patients who smoked a half pack or more of cigarettes(More)
A considerable section of the population in India accesses the services of individual private medical practitioners (PMPs) for primary level care. In rural areas, these providers include MBBS doctors, practitioners of alternative systems of medicine, herbalists, indigenous and folk practitioners, compounders and others. This paper describes the profile,(More)
BACKGROUND The ability to utilize shorter implants in the reconstruction of the posterior maxilla would, theoretically, simplify therapy by lessening the need for augmentation surgery. The purpose of this retrospective study was to assess the success and failure rates of < or = 9 mm or shorter implants in the maxillary posterior regions restored with(More)
Silver nanowire films are promising alternatives to tin-doped indium oxide (ITO) films as transparent conductive electrodes. In this paper, we report the use of vacuum filtration and a polydimethylsiloxane (PDMS)-assisted transfer printing technique to fabricate silver nanowire films on both rigid and flexible substrates, bringing advantages such as the(More)
This work presents the comparison and combination of neural networks with decision trees on the application of wine classification. Neural networks are first trained and then combined with decision trees in order to extract knowledge learnt in the training process. Artificial neural networks are used for the classification of Italian wines obtained from a(More)
Coexistence of metallic and semiconducting carbon nanotubes in as-grown samples sets important limits to their application in high-performance electronics. We present the metal-to-semiconductor conversion of carbon nanotubes for field-effect transistors based on both aligned nanotubes and individual nanotube devices. The conversion process is induced by(More)
BACKGROUND Onychomycosis is a fungal disease of the nail apparatus caused by both dermatophytic and nondermatophytic strains. Treatment involves long duration antifungal therapy. However, long treatment duration without identifying the causative species may lead to resistance. Confirmation of diagnosis and speciation by culture before administering(More)
The use of anti-platelet therapy has reduced the mortality and morbidity of cardiovascular disease remarkably. A considerable number of patients presenting before a dentist or periodontist give a history of anti-platelet therapy. A clinical dilemma whether to discontinue the anti-platelet therapy or continue the same always confronts the practitioner.(More)
