By the current paper, lift force that is an important characteristic of a planing hull is calculated. To accomplish this task, Morabito’s mathematical model that has been previously derived for prediction of total pressure distribution on planing hulls is utilized. These equations are not restricted to any specific mean wetted length and can be used for planing hulls with large value of mean we...

objectives: scaling and root planing (srp) is one of the most commonly used procedures during periodontal treatment. the aim of this study was to evaluate the root surface roughness after srp with erbium: yttrium aluminum garnet (er:yag) laser compared to ultrasonic and hand instruments.   materials and methods: in this experimental study, 56 extracted sound single-rooted teeth with moderate le...

AIM To compare the outcomes of surgical periodontal therapy with and without initial scaling and root planing. METHODS Twenty-four patients with severe chronic periodontitis were enrolled in this pilot, randomized controlled clinical trial. Patients were equally allocated into two treatment groups: Control group was treated with scaling and root planing, re-evaluation, followed by Modified Wi...

OBJECTIVE The aim of this study was to evaluate clinical efficacy of InGaAsP diode laser as adjunct to traditional scaling and root planing. BACKGROUND DATA The use of laser is one of the most recent methods in nonsurgical periodontal treatment. Efficacy and side effects of each type of laser treatment have yet to be determined. METHODS Thirty patients suffering from moderate periodontal di...

The problems of re-configuration and re-planing in multi-agent systems exploring acquaintance models of their behavior are discussed throughout this paper. Both the autonomous and supervised methods of replaning are distinguished. The advantages of the tri-base acquaintance models used in the ProPlanT production planning system for solving the reconfiguration and re-planing tasks are sketched.

Planing properties of seven Australian plantation-grown eucalypts were evaluated to provide recommendations on how these species should be machined and considered for the manufacture of high quality furniture and furnishings. The surface quality produced for each species was evaluated using eight planing conditions. All species performed well producing equivalent or better results than mature t...

In the present paper, a mathematical model is used in order to predict the longitudinal distribution of dynamic pressure on planing hulls. The present model is based on the empirical equations resulted from multitude of experiments that have been carried out over the years on planing boats. These empirical equations are able to predict a longitudinal section of the pressure distribution. The ob...

The efficacy of scaling and root planing using various periodontal rotary instruments was examined. Eighty extracted human teeth with a history of periodontal disease were divided into four groups of 20 and subjected to one of the following procedures: Use of 1) a Root Burnisher, 2) a Perio Planing Bur (both rotating instruments for contra angle handpieces), 3) a Tooth Planing Bur (rotating ins...

AIMS AND OBJECTIVES The aim of the present study was to evaluate the clinical and microbiological efficacy of locally delivered 1% curcumin gel as an adjunct to scaling and root planing in the treatment of chronic periodontitis. MATERIALS AND METHODS The study group consisted of 25 patients, belonging to both sex, aged between 21-45 years. All patients diagnosed as chronic periodontitis with ...
