The Upper Pleistocene submarine fan deposits in the Northern Gulf of Mexico have proven to be valuable targets for hydrocarbon exploration and extraction. The Garden Banks Area, 170 miles Southwest of Lafayette, Louisiana, is situated on the western flank of a submarine fan complex in the Northern Gulf of Mexico. The Garden Banks Area has producing wells in the Upper Pleistocene deep marine san...

The build-up of soot deposits on cold wall surfaces is a problem of unknown significance for combustion applications. Soot deposits are due to thermophoretic transport and are generally ignored in theoretical and numerical analysis. We examine here the relationship between the rate of soot deposition and the wall convective heat flux, using both Direct Numerical Simulation (DNS) and Large Eddy ...

Gou A large number of candidate open-basin lakes (low-lying regions with both inlet valleys and an outlet valley) have been identified and mapped on Mars and are fed by valley network systems that were active near the Noachia...

The aim of this study was to test the possibility of the concomitant formation of calculus deposits and caries from dentin caries model for short time in situ periods. Six volunteers wore palatal removal appliances with four polished dentin specimens protected from intra-oral mechanical forces for up to 14 days. Each volunteer applied a 50% sucrose solution (four times a day) on the specimens a...

Background: In spite of the high incidence of gingivitis and periodontal disease in the hemophiliac population, few are known about the influence of oral health condition as risk factor for bleeding after dental extraction in this patient population. The aim of this report is to use a group of patients under oral anticoagulation as a model of acquired bleeding disorder to show the importance of...

Aim. Dental floss is the most effective means for the removal of bacterial plaque from proximal tooth areas. The efficacy of the use of dental floss was evaluated, regardless of its commercial form, in individual oral hygiene practice. Material and methods. A parallel clinical study of 58 subjects was performed over a period of four weeks. In order to assess the oral hygiene and gingival status...

Homo floresiensis is an extinct, diminutive hominin species discovered in the Late Pleistocene deposits of Liang Bua cave, Flores, eastern Indonesia. The nature and evolutionary origins of H. floresiensis' unique physical characters have been intensively debated. Based on extensive comparisons using linear metric analyses, crown contour analyses, and other trait-by-trait morphological compariso...

Clarkson and Magos (2006) provide their perspectives on the toxicology of mercury vapor and dental amalgam. As scientists who are involved in preparing a German federal guideline regarding dental amalgam, we welcome additional scientific data on this issue. However, Clarkson and Magos do not present all the relevant studies in their review. The additional data provided here show that: (a) Denta...
