OBJECTIVE To examine protocol fidelity among teachers involved in a six-month cluster-randomized physical activity (PA) intervention. METHODS In 2011, preschools in Springfield, MA were randomized to short bouts of structured PA (SBS-PA, n=5) or unstructured playtime (UPA, n=5). SBS-PA provided structured PA in the classroom during the first 10 min of gross-motor playtime followed by 20 min o...

This study investigated the effect of benzalkonium chloride (BAC) modification of two adhesive systems on long-term bond strength to normal and artificially eroded dentin. A total of 128 extracted human molars were sectioned and the buccal and oral surfaces of each molar were ground until the dentin. One half was left untreated (normal dentin) while the other half underwent artificial erosion. ...

Introduction: Sick Building Syndrome (SBS) is a set of undesirable physical and psychological conditions whose symptoms appear when entering the building and disappear after leaving it. The most well-known symptoms of SBS include problems of nervous and respiratory systems and skin. Since nurses spend many hours in the hospital and enclosed spaces, they are exposed to many factors related to th...

Short bowel syndrome (SBS) is characterized by severe intestinal malabsorption following restrictive surgery. The objective of this study was to determine the functional contribution of SBS-microbiota after resection. It is well-known that SBS-microbiota displayed specific features with a prevalence of Lactobacillus, a low amount of some anaerobic microbes (Clostridium leptum) and an accumulati...

INTRODUCTION Transmitted drug-resistance mutations (TDRM) may hamper successful anti-HIV-1 therapy and impact future control of the HIV-1 epidemic. Recently infected, therapy-naïve individuals are best suited for surveillance of such TDRM. In this study, TDRM, detected by next-generation sequencing (NGS) were compared to those identified by Sanger-based population sequencing (SBS) in recently i...

We present a method to automatically detect sentence boundaries(SBs) in Japanese speech transcriptions. Our method uses a Japanese morphological analyzer that is based on a cost calculation and selects as the best result the one with the minimum cost. The idea behind using a morphological analyzer to identify candidates for SBs is that the analyzer outputs lower costs for better sequences of mo...

In this investigation, rheological properties of three different polymer-modified bitumen compounds containing recycled polyethylene terephthalate (R-PET), crumb rubber (CR) and poly (styrene-butadiene-styrene) (SBS) are evaluated and compared. The modified samples were tested by a dynamic shear rheometer (DSR) where complex modulus (G*), phase angle (δ) and rutting resistance (G*/Sinδ) of spec...

In this research, the efficiency of Recycled Glass Powder (RGP) is evaluated for improvement of polymer-modified bitumen and asphalt mixture performance. An extensive laboratory programm was undertaken for polymer-modified bitumen including Crumb Rubber (CR), Styrene Butadiene Styrene (SBS) and Styrene Butadiene Rubber (SBR). Rheological and mechanical proper...

OBJECTIVE To evaluate the effects of contamination by either blood or a hemostatic agent on the shear bond strength (SBS) of orthodontic buttons. METHODS We used 45 freshly extracted, non-carious, impacted third molars that were divided into 3 groups of 15. Each tooth was etched with 37% phosphoric acid gel for 30 s. Human blood or the blood stopper agent was applied to the tooth surface in g...

The polarization properties of stimulated Brillouin scattering (SBS) amplification or attenuation in standard single-mode fibers are examined through vectorial analysis, simulation and experiment. Vector propagation equations for the signal wave, incorporating SBS and birefringence, are derived and analyzed in both the Jones and Stokes spaces. The analysis shows that in the undepleted pump regi...
