    Get PDF
    In sports, dental trauma is the main link between sport and dentistry. Sports dentistry is the treatment of sporting oral / facial injuries and associated oral disorders and manifestations. Sporting practices have been found to be responsible for 13 per cent of total oral trauma in children. It is emphasized that from high schools to professional teams there is a great need for a "Team Dentist." In this review, we discuss the relationship between sport and dentistry, and the importance of educating parents, teachers, and children on sport-related injury prevention

    INTRODUCTION: "Dry socket" was first described by Crawford in literature in 1896. When people are recognizing that current medicine is not the soul cure for diseases, we look back to the past for potential remedies with the least possible side-effectiveness. So the objective of this study was to evaluate the effectiveness of honey and aloevera on healing of post extraction wounds. MATERIAL AND METHODS: Honey and aloe-vera were prepared by mixing with sterilized cotton. The socket involved was separated by dry autoclaved cotton rolls from the rest of the oral cavity, then honey/aloe-vera was inserted into the respective groups. All patients were advised to avoid solid and liquid diets for 30 minutes after the treatment. Dressings were changed on 3rd day and on 7th day and sockets were evaluated. RESULTS: When the intra-group comparison of honey (p-value=0.003) and aloe-vera (p-value=0.000) was done, both were found to be statistically significant in the healing of dry socket. When the inter-group comparison was done between honey and aloe-vera, Aloe-vera had high healing capacity and was found to be highly statistically significant (p-value=0.001). DISCUSSION: When the intra-group comparison of honey and aloe-vera was done, both were found to be statistically significant in the reduction of dry socket. When the inter-group comparison was done between honey and aloe-vera, Aloe-vera had high healing capacity and was found to be highly statistically significant (p-value=0.00). CONCLUSION: From the analysis, it can be inferred that aloe vera and honey are healthy, natural and user-friendly substitute adjuncts that might be feasible to promote healing of extraction sockets

    INTRODUCTION: In India, the percentage of deaths caused by tobacco smoking is anticipated to rise from 1.4 percent in 1990 to 13.3 percent by 2020.Health care experts have done their best to persuade and counsel users to quit the habit through their collaborative efforts. AIM AND OBJECTIVES: Assessment of dentistry students' attitudes and practices concerning tobacco cessation strategies, as well as the role of information in their promotion. MATERIALS AND METHODS: This cross-sectional survey was carried out at the Institute of Dental Sciences, Bareilly among the dental professionals, i.e. final year, interns, postgraduates students. The questionnaire was designed to test the knowledge, attitude, and practice of dental students regarding tobacco use. The self-administered survey included a set of questions. Descriptive statistics and Chi-square test had been used to test associations between their responses among age, qualification, and academic year using statistical package for social sciences (SPSS) version 22. RESULTS: A total of 300 surveys were sent out, with a 96.39 percent response rate. There were 54 percent females and 46 percent males among the 250 participants. Approximately 68 percent of people were between the ages of 20 and 23. In the current study, 32.4 percent were seeking MDS and 67.6 percent were pursuing BDS. Nearly half of those prefer to prescribe nicotine replacement therapy (NRT) as a cigarette cessation recommendation to patients, followed by self-quitting at 48% and pharmaceutical approaches at 1.2 percent. DISCUSSION: More than half of the respondents had an average level of awareness of smoking cessation therapies, and the majority of them had a favorable attitude toward their provision. As a result, it is important to persuade students to develop an interest in learning about tobacco quitting strategies

    Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

    Get PDF
    Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente

    Climatic risks and impacts in South Asia: extremes of water scarcity and excess

    Get PDF
    This paper reviews the current knowledge of climatic risks and impacts in South Asia associated with anthropogenic warming levels of 1.5°C to 4°C above pre-industrial values in the 21st century. It is based on the World Bank Report “Turn Down the Heat, Climate Extremes, Regional Impacts and the Case for Resilience” (2013). Many of the climate change impacts in the region, which appear quite severe even with relatively modest warming of 1.5–2°C, pose significant hazards to development. For example, increased monsoon variability and loss or glacial meltwater will likely confront populations with ongoing and multiple challenges. The result is a significant risk to stable and reliable water resources for the region, with increases in peak flows potentially causing floods and dry season flow reductions threatening agriculture. Irrespective of the anticipated economic development and growth, climate projections indicate that large parts of South Asia’s growing population and especially the poor are likely to remain highly vulnerable to climate change

    Search for High-Mass Resonances Decaying to τν in pp Collisions at √s=13 TeV with the ATLAS Detector

    Get PDF
    A search for high-mass resonances decaying to τν using proton-proton collisions at √s=13 TeV produced by the Large Hadron Collider is presented. Only τ-lepton decays with hadrons in the final state are considered. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 36.1 fb−1. No statistically significant excess above the standard model expectation is observed; model-independent upper limits are set on the visible τν production cross section. Heavy W′ bosons with masses less than 3.7 TeV in the sequential standard model and masses less than 2.2–3.8 TeV depending on the coupling in the nonuniversal G(221) model are excluded at the 95% credibility level

    Performance of missing transverse momentum reconstruction with the ATLAS detector using proton–proton collisions at √s = 13 TeV

    Get PDF
    The performance of the missing transverse momentum (EmissT) reconstruction with the ATLAS detector is evaluated using data collected in proton–proton collisions at the LHC at a centre-of-mass energy of 13 TeV in 2015. To reconstruct EmissT, fully calibrated electrons, muons, photons, hadronically decaying τ -leptons, and jets reconstructed from calorimeter energy deposits and charged-particle tracks are used. These are combined with the soft hadronic activity measured by reconstructed charged-particle tracks not associated with the hard objects. Possible double counting of contributions from reconstructed charged-particle tracks from the inner detector, energy deposits in the calorimeter, and reconstructed muons from the muon spectrometer is avoided by applying a signal ambiguity resolution procedure which rejects already used signals when combining the various EmissT contributions. The individual terms as well as the overall reconstructed EmissT are evaluated with various performance metrics for scale (linearity), resolution, and sensitivity to the data-taking conditions. The method developed to determine the systematic uncertainties of the EmissT scale and resolution is discussed. Results are shown based on the full 2015 data sample corresponding to an integrated luminosity of 3.2 fb−1

    Get PDF
    The Tile Calorimeter is the hadron calorimeter covering the central region of the ATLAS experiment at the Large Hadron Collider. Approximately 10,000 photomultipliers collect light from scintillating tiles acting as the active material sandwiched between slabs of steel absorber. This paper gives an overview of the calorimeter’s performance during the years 2008–2012 using cosmic-ray muon events and proton–proton collision data at centre-of-mass energies of 7 and 8TeV with a total integrated luminosity of nearly 30 fb−1. The signal reconstruction methods, calibration systems as well as the detector operation status are presented. The energy and time calibration methods performed excellently, resulting in good stability of the calorimeter response under varying conditions during the LHC Run 1. Finally, the Tile Calorimeter response to isolated muons and hadrons as well as to jets from proton–proton collisions is presented. The results demonstrate excellent performance in accord with specifications mentioned in the Technical Design Report

    Measurement of the t¯tZ and t¯tW cross sections in proton-proton collisions at √s=13 TeV with the ATLAS detector

    Get PDF
    A measurement of the associated production of a top-quark pair (t¯t) with a vector boson (W, Z) in proton-proton collisions at a center-of-mass energy of 13 TeV is presented, using 36.1  fb−1 of integrated luminosity collected by the ATLAS detector at the Large Hadron Collider. Events are selected in channels with two same- or opposite-sign leptons (electrons or muons), three leptons or four leptons, and each channel is further divided into multiple regions to maximize the sensitivity of the measurement. The t¯tZ and t¯tW production cross sections are simultaneously measured using a combined fit to all regions. The best-fit values of the production cross sections are σt¯tZ=0.95±0.08stat±0.10syst pb and σt¯tW=0.87±0.13stat±0.14syst pb in agreement with the Standard Model predictions. The measurement of the t¯tZ cross section is used to set constraints on effective field theory operators which modify the t¯tZ vertex
