A tunneled planing craft is a high-speed boat with two tunnels over the hull bottom that are designed to improve vessel’s performance. Hydrodynamic performance of hulls in calm-water well-known, however, current information on wave conditions limited. In this study, different degrees freedom heave and pitch motions studied regular waves by using computational fluid dynamics (CFD) method based U...

AIMS The objective of this study was to investigate the effect of the systemic administration of metronidazole and amoxicillin as an adjunct to initial periodontal therapy in patients with moderate to severe chronic periodontitis. METHODS AND MATERIALS This randomized, double blind, placebo controlled parallel study involved 50 adult patients with untreated periodontitis who were randomly ass...

Periodontally affected root surfaces are hyper mineralized, and contaminated with cytotoxic and other biologically active substances especially endotoxins which play a pivotal role in preventing new connective tissue attachment to the exposed root surface. Following root planing the instrumented root surface is invariably covered by smear layer containing remnants of dental calculus, contaminat...

Waste management involves an efficient planing of collectionvehicles and corresponding crews. We present an optimization model and algorithm for the crew scheduling problem which is the second part of an integrative solution approach. We differentiate between a network based duty generation phase and a duty optimization phase where an optimal set of annual duties for all employees is selected.

BACKGROUND Enamel matrix derivative (EMD) is a composite of proteins that was demonstrated histologically to work as an adjunct to periodontal regenerative surgical therapy. The purpose of this study was to evaluate the clinical and histologic effects of EMD as an adjunct to scaling and root planing. METHODS Four patients with severe chronic periodontitis and scheduled to receive complete den...
