Day-Scale Variability of 3C 279 and Searches for Correlations in Gamma-Ray, X-Ray, and Optical Bands
Light curves of 3C 279 are presented in optical (R-band), X-rays (RXTE/PCA), and γ rays (CGRO/EGRET) for 1999 Jan–Feb and 2000 Jan–Mar. During both of those epochs the γ-ray levels were high, and all three observed bands demonstrated substantial variation, on time scales as short as one day. Correlation analyses provided no consistent pattern, although a rather significant optical/γ-ray correla...
The dynamical evolution of young supernova remnants (YSNRs) is governed by the density distribution in the ejecta and in the ambient medium. Analytic solutions are available for spherically symmetric expansion, including the transition from the ejecta-dominated stage to the Sedov-Taylor stage. YSNRs serve as valuable physics laboratories, in which we can study nucleosynthesis, the early evoluti...
Object instance detection finds where a specific object instance is in an image or a video frame. It is a variation of object detection, but distinguished on two points. First, object detection focused on a category of object, while object instance detection focused on a specific object. For instance, object detection may work to find where toothpaste is in an image, while object instance detec...

A comparison of the desensitising efficacy of two commercially available dentifrices with different modes of action was conducted in a randomised, examiner-blind, two-arm, parallel group, 8-week, longitudinal clinical study. Dentifrice A, (Sensodyne Multi Action Iso-Active), contained 50000 ppm KNO(3) and 1450 ppm fluoride as NaF. Dentifrice B, Colgate Sensitive Pro-Relief, contained a combinat...
This study evaluated the abrasiveness of mechanical and combined methods of denture hygiene, by the analysis of mass loss and surface roughness. Acrylic resin specimens (Plexiglass) were brushed by a tooth brushing machine (Mavtec) with a soft brush (Tek) and water (control) or four dentifrices (Sorriso, Colgate, Polident and Corega) (Experimental groups) for 50 min, representing one year of br...

A laboratory test was used to assess the inhibition of growth of oral bacteria by three modern commercial mouthrinses containing either cetylpridinium chloride, CPC (Macleans), phenolic compound (Colgate Plax) or glycerin/triclosan (Listerine); which were used unsupervised in a placebo-controlled study involving fortyfive healthy adults. Subjects were divided into 3 groups and their saliva samp...
The aim of this study was to evaluate the in vitro activity of dentifrices containing the hydroalcoholic extract of the ripe fruit of Eugenia uniflora L. (Surinam cherry) on Streptococcus oralis (ATCC 10557) and Lactobacillus casei (ATCC 7469). Five dentifrices were used: D1: containing hydroalcoholic extract of Eugenia uniflora L.; D2: containing fluoride and hydroalcoholic extract of Eugenia ...
The aim of this study was to determine the action of desensitizing materials on bovine dentin. Four extracted healthy bovine molars were selected out of which 5 blocks from cervical region of each tooth were obtained, resulting in a 5x5mm final area. To compose the negative control group (group B), the samples were separated and not submitted to any treatment. For the positive control (Group A)...
