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 ...

The objective of this study was to examine potential benefits of using laser therapy for secular decontamination in conjunction with scaling and root planing in the treatment of chronic periodontitis. The study was performed on 173 teeth in 14 patients in a split-mouth design, one side received scaling and root planing followed by laser therapy using a carbon dioxide (CO2) laser with an ablativ...

This paper presents a parametric study of steel I- beam with stepped flanges by using finite element analysis. Stepped flange beam is used in structures to decrease the negative bending moments near interior supports that causes failure due to buckling. Steps in the cross section can be achieved by adding cover plates to the beam flanges, changing the size of the hot rolled section, or changing...

Background: Antimicrobial agent has been effectively used systemically and locally in management of periodontal disease. Local drug has an advantage of higher antimicrobial concentration in subgingival site. Presently large number of herbal product researches in oral use in various from. The study researches neem extract when incorporated in LLD system used as adjunct to scaling and root planin...

Local anesthesia is administered to control pain, but it may induce fear and anxiety. Root planing is a non-surgical periodontal therapy; however, when it is performed in an extensive manner, some tissue removal is inevitable. Notably, this removal may be so painful that local anesthesia is required to be administered to the area scheduled for the treatment. Although patients tend to accept roo...

The wake waves generated by the steady movement of a planing hull are analyzed means towing tank tests. Two sets waves, including divergent and transverse identified then analyzed. wave period is seen to decrease increase in speed vessel. These damp temporally. mechanisms that lead damping were found depend on orbital Reynolds number semi-planing regime, though in-planing regime function boat. ...
