This study presents the results of cavitation tunnel tests carried out with model propeller of a Fisheries Research Vessel (FRV) and those of noise measurements with its full-scale propeller to validate the low-noise performance of this propeller. The tests involve the simulation of a target wake using a wake screen and the determination of the nature and extent of the observed cavitation behin...

Contra-rotating propellers have renewed interest from the naval architecture community, because of the recent development of electric propulsion drives and podded propulsors. Contrarotating propulsion systems have the hydrodynamic advantages of recovering part of the slipstream rotational energy which would otherwise be lost utilizing a conventional screw propeller system. The application of th...

Body piercing, a growing trend especially in young people, is often complicated by severe infections. We present a case of acute bacterial endocarditis by Staphylococcus aureus complicated by multiple cerebral, kidney, spleen embolisms in a young girl, with no known previous cardiac abnormalities, following the piercing of nasal septum. This case highlights the importance of education of patien...

High spin levels in 'Nb and 'Zr have been studied with the reactions Sr{GI,i, 3n) ~ Nb and 8 Sr(GLi, P2n) 'Zr by pulsed-beam-p, p-p, and p-W(&) measurements. Isomers were found which agree with theoretical predictions: a v =5.42 + 0.18-p, sec state at 2035 keV in Nb, l(g&g2) pqg2, $ ), and a v=6.15+0.50-psec state at (8188) keV in 'Zr, [(g9~2) &&d5y2, ~~+). The ~+9y2P, y2d&y2, + ) state in ~'Zr...

PURPOSE To develop a methodology for cannulating porcine retinal venules using a robotic assistive arm after inducing a retinal vein occlusion using the photosensitizer rose bengal. METHODOLOGY Retinal vein occlusions proximal to the first vascular branch point were induced following intravenous injection of rose bengal by exposure to 532nm laser light delivered by slit-lamp or endolaser prob...

Tattooing and body piercing are now worldwide fashion crazes. The health risks associated with these procedures are as yet unclear. This article examines the prevalence of body decoration and the associated health risks within the Australian population using a random sample survey of individuals aged 14 years and over, collected between June and September 1998 (n = 10,030). The results show tha...

BACKGROUND Studies have shown conflicting results on the association between nickel exposure from orthodontic appliances and nickel sensitization. OBJECTIVES & METHOD: In a cross-sectional study, we investigated the association between nickel sensitization and exposure to orthodontic appliances and piercings. 4376 adolescents were patch tested following a questionnaire asking for earlier pierci...

11 Anaphylaxis after Topical Application of Bacitracin: A Case Report Mona Al-Ahmad, Sean Mace, University of Toronto, Toronto, ON Introduction: We present a case of anaphylaxis following repeated application of bacitracin. Method: A case report of a twenty-three year old woman with no prior allergic history who underwent body piercing of the navel. A low grade local infection developed at the ...
