Evidence for νμ→ντ\nu_\mu \to \nu_\tau appearance in the CNGS neutrino beam with the OPERA experiment

The OPERA experiment is designed to search for $\nu_{\mu} \rightarrow \nu_{\tau}$ oscillations in appearance mode i.e. through the direct observation of the $\tau$ lepton in $\nu_{\tau}$ charged current interactions. The experiment has taken data for five years, since 2008, with the CERN Neutrino to Gran Sasso beam. Previously, two $\nu_{\tau}$ candidates with a $\tau$ decaying into hadrons were observed in a sub-sample of data of the 2008-2011 runs. Here we report the observation of a third $\nu_\tau$ candidate in the $\tau^-\to\mu^-$ decay channel coming from the analysis of a sub-sample of the 2012 run. Taking into account the estimated background, the absence of $\nu_{\mu} \rightarrow \nu_{\tau}$ oscillations is excluded at the 3.4 $\sigma$ level.Comment: 9 pages, 5 figures, 1 table

Influence des rejets des eaux usées sur la composition des eaux de surface et des sédiments superficiels du lac Merja Fouarate au Maroc

Résumé Le site objet du présent travail est un lac situé à proximité d'une grande agglomération urbaine. Cette dépression qui communique avec la nappe phréatique sousjacente est devenue actuellement un exutoire dans lequel sont déversés, sans aucun traitement préalable, les effluents domestiques et industriels des quartiers avoisinants. Dans le but d'évaluer l'influence des rejets déversés sur la qualité des eaux du site étudié, la composition des eaux de surface et des sédiments superficiels du lac en basses eaux, ainsi que celle des rejets s'y déversant, a été déterminée. L'évolution spatiotemporelle de quelques paramètres physico-chimiques a été suivie sur les eaux prélevées. Les résultats obtenus montrent que les eaux étudiées sont dures et assez chargées en sels dissous et en matière en suspension; elles présentent une minéralisation importante se rapprochant en général des valeurs limites indiquées par la directive de la CEE et la réglementation française et dépassant celles fixées par l'Organisation Mondiale de la Santé (OMS). Les eaux des rejets et des berges du lac ne sont pas conseillées à l'utilisation en irrigation. Les eaux superficielles du lac subissent l'influence néfaste des eaux usées de la ville de Kénitra. L'impact de cette pollution est plus ressenti au niveau des eaux et des sédiments superficiels des berges et s'étend même jusqu'à la zone centrale du lac. La nature des terrains avoisinants le lac contribue aussi à la dégradation de la qualité des eaux du lac, suite au lessivage en période de crue. Mots-clés : Lac Merja Fourate, pollution, eaux usées, composition chimique, eaux de surface, sédiments Abstract Influence of the worn water on the lake surface water and surface sediments com position of the lake Merja Fouarate in Morocco The site subject of this work is a lake located near an urban center. This depression which communicated with the subjacent ground water became currently a discharge site in which are poured domestic and industrial effluents without any preliminary treatments. The aim of this study is to evaluate the influence of the worn water on the lake water quality. In this way we have determined the lake surface water and the surface sediments composition. The obtained values have been compared to worn water case. The space-time evolution of some physicochemical parameters was monitored. The results obtained show that studied water is rather charged out of dissolved salt and suspended matter. They also show a hard water character, which presents in general bringing closer the limiting values indicated by the directive to the European Communities and the French regulation and exceeding that fixed by the World Health Organization. This leads that water of the rejections and the banks can not be used in the irrigation systems. The surface waters of the lake are subject to the harmful influence of wastewater of Kénitra town. The impact of this pollution is felt more on the level of water and surface sediments of the banks and extends even to the central zone of the lake. The nature of the soil contributes also by following scrubbing in a rainy and rising period.

Explosive Push-ups: From Popular Simple Exercises to Valid Tests for Upper-Body Power

Zalleg, D, Ben Dhahbi, A, Dhahbi, W, Sellami, M, Padulo, J, Souaifi, M, Be\u161lija, T, and Chamari, K. Explosive push-ups: From popular simple exercises to valid tests for upper-body power. J Strength Cond Res XX(X): 000-000, 2018-The purpose of this study was to assess the logical and ecological validity of 5 explosive push-up variations as a means of upper-body power assessment, using the factorial characterization of ground reaction force-based (GRF-based) parameter outputs. Thirty-seven highly active commando soldiers (age: 23.3 \ub1 1.5 years; body mass: 78.7 \ub1 9.7 kg; body height: 179.7 \ub1 4.3 cm) performed 3 trials of 5 variations of the explosive push-up in a randomized-counterbalanced order: (a) standard countermovement push-up, (b) standard squat push-up, (c) kneeling countermovement push-up, (d) kneeling squat push-up, and (e) drop-fall push-up. Vertical GRF was measured during these exercises using a portable force plate. The initial force-supported, peak-GRF and rate of force development during takeoff, flight time, impact force, and rate of force development impact on landing were measured. A significant relationship between initial force-supported and peak-GRF takeoff was observed for the countermovement push-up (CMP) exercises (standard countermovement push-up, kneeling countermovement push-up, and drop-fall push-up) and squat push-up (SP) exercises (standard squat push-up and kneeling squat push-up) (r = 0.58 and r = 0.80, respectively; p < 0.01). Furthermore, initial force supported was also negatively correlated to a significant degree with flight time for both CMP and SP (r = -0.74 and r = -0.80; p < 0.01, respectively). Principal component analysis (PCA) showed that the abovementioned 6 GRF-based variables resulted in the extraction of 3 significant components, which explained 88.9% of the total variance for CMP, and 2 significant components, which explained 71.0% of the total variance for SP exercises. In summary, the PCA model demonstrated a great predictive power in accounting for GRF-based parameters of explosive push-up exercises, allowing for stronger logical and ecological validity as tests of upper-body power. Furthermore, it is possible to adjust the intensity level of the push-up exercise by altering the starting position (i.e., standard vs. kneeling)

Hemoglobin, hematocrit and plasma volume variations following combined sprint and strength: Effect of advanced age

Summary Objectives The study investigated the effect of combined sprint and resistance training (CSRT) on red blood cell (RBC) count, hemoglobin (Hb), hematocrit (Hct), plasma volume (PV) variation at rest and during exercise. Equipment and methods Twenty-eight moderately trained were randomly assigned into a young trained (YT), young control (YC), middle-aged trained (MAT), and middle-aged control (MAC) group. Before (P1), and after (P2) CSRT, blood samples were collected at rest and after exercise. Results At P1, Hct was significantly (P .05) age-effect between MAT and YT was observed for Hct. Conclusion CSRT increases RBC count and Hb in middle-aged men, and ameliorates the effect of age in Hct. Such adaptations may improve cardiovascular fitness of middle-aged individuals, and may be preventative of subsequent declines with age

Viscous dissipation effect on amplitude and oscillating frequency of heat transfer and electromagnetic waves of magnetic driven fluid flow along the horizontal circular cylinder

The significant importance of present research is to remove the extreme temperature along the magnetic driven horizontal circular cylinder. The induced electromagnetic field is applied around the surface of cylinder. The main novelty of current research is to control thermal and magnetic boundary layer in the presence of viscous dissipation and induced electromagnetic field. The dimensional mathematical form is developed with defined boundary conditions. The dimensional equations are transformed into dimensionless equations to generate physical factors. The primitive form is used to reduce dimensionless equations into convenient form for smooth algorithm. The finite difference method with Gaussian elimination technique is applied for numerical results in FORTRAN language tool. The velocity, temperature and electromagnetic field are sketched graphically with asymptotic sequence. The oscillatory shear stress, oscillating heat rate and periodical current density is plotted graphically and numerically. It is found that fluid velocity improves significantly as buoyancy force increases around each position. It is noticed that the increasing oscillations in heat transfer are sketched for maximum choice of Prandtl number. It is found that the maximum oscillations in current density are obtained for each Eckert parameter. It is noticed that the significant distribution in temperature profile is obtained in the presence of viscous dissipation and magnetic field
