Nostratollah Montajabi and HamidrezaTajdari

Abstract:
We studied the effect of four irrigation regime on Mahdavi wheat performance and water use efficiency, straw, weight of 1000 grains, protein percentage in Esfahan province, Iran according to randomized complete blocks design. irrigation treatments included four irrigation interval after T1=50, T2=75, T3=100, and T4=125 mm evaporation from a Class A pan in four replications. Fertilizers were consumed according to the soil test, soil productivity, and plant nutrition as 350 kg/yr at the first year and 250 kg/yr at the second year and triple super-phosphate and potassium sulfate fertilizers, each 100 kg/ha in year. The results showed that the effect of year on grain weight, straw, water use efficiency, and protein percentage was significant in 1% level. Grain protein of the second year was more than that in the first year significantly. The effects of irrigation treatments on Grain yield, Grain protein percentage and water use efficiency by Grain production were significant in 5% for Grain and in 1% for straw. Grain and straw yield were decreased by changing irrigation interval in T1, T3, and T4 periods, which were significant in T3 and T4. Grain protein percentage in treatment T1 was most and its diference with T3 was significant. Water use efficiency significantly increased by elongation of irrigation interval. Least water use efficiency was for T1 with 0.99 and most water use efficiency was for T4 with 1.24 kg grain per m3.

Abstract:
Dans le cadre de la surveillance et du contrôle des maladies à transport hydrique, une étude prospective de cinq mois a été lancée depuis le mois de Mai au mois de Septembre 2014.
Cette étude a pour objectif la recherche de la présence des levures et des moisissures ainsi que l’évaluation préliminaire de la qualité hygiénique des eaux conditionnées.
L’étude a porté sur quatre-vingt-douze (92) échantillons des eaux embouteillées, acheminés des différentes régions.
Sur le plan bactériologique, et selon la Norme Marocaine 03.7.001 de l’année 2006, 35% des eaux analysées ont présenté une forte contamination par la flore mésophile aérobie totale avec une densité maximale de 3.6 103UFC/ 100 ml. Egalement la recherche des levures et des moisissures montre que 80 % des eaux analysées ont été contaminées avec concentrations allant de 0,1 101 à 3,4 102UFC/100 ml.
Aucune présence des Clostridium sulfito-réducteurs et des Pseudomonas aeruginosa n’a été noté. En effet, ces microorganismes ont été absents dans la totalité des eaux analysées.
La consommation d’une eau potable est un élément important pour la prévention contre les maladies hydriques. De ce fait, cette eau de consommation doit bénéficier d’une attention particulière.
Elle ne doit contenir ni substances chimiques dangereuses, ni germes pathogènes et nocifs pour la santé. C’est pourquoi, l’ensemble des acteurs dans le domaine de l’eau doivent veiller en permanence sur sa qualité.
Keywords: Eau conditionnée, maladies hydriques, levures et moisissures, qualité bactériologique, santé publique.


Daily Protein Intake With and Without Protein Supplementation in Kuwaiti Male Bodybuilders & Swimmers

Mohammed Alkatan, Bader Aldimkhi, and Kazem J. Ghloum

Abstract:
Introduction: Resistance training and swimming are becoming increasing popular in the Middle East, especially in Kuwait. Adequate protein intake is essential to achieving a positive net muscle protein balance and increasing skeletal muscle protein synthesis. In addition to using protein supplements, such as whey and casein protein, bodybuilders and swimmers consume more protein in their diet than is necessary to meet training-dependent protein requirements. Thus, the purpose of the present study was to determine the daily protein intake of Kuwaiti male, collegiate recreational bodybuilders and high-level swimmers and discern the type and timing of supplementary protein intake.
Methods: Nineteen bodybuilders and 23 swimmers, all of whom were Kuwaiti male, collegiate recreational athletes, volunteered for the study. All subjects completed a 24-hour dietary recall to estimate total daily protein intake with and without protein supplement consumption.
Results: Bodybuilders who use protein supplements have higher daily protein consumption (149 g/day) compared with those whose protein consumption is from food sources alone (118 g/day). For swimmers, protein consumption was not significantly higher when protein supplements were consumed. The preferred protein supplement for both bodybuilders and swimmers was whey protein. In regards to the timing of post-exercise protein supplement consumption, most participants in both the bodybuilders and swimmers groups supplemented 1 hour after training.
Conclusion: Kuwaiti male, collegiate recreational bodybuilders who combine protein intake from food sources and protein supplements do not exceed recommended levels. Additionally, protein consumption would remain in the recommended range should bodybuilders fail to consume their daily protein supplement. Kuwaiti high-level swimmers should consume protein supplements to meet the recommended daily protein intake.

Abstract:
Le stress professionnel est omniprésent dans toutes les entreprises, notamment dans le secteur de transport public. En fait, il présente un grand problème de santé publique au Maroc. Néanmoins, peu de travaux marocains l’abordent auprès des métiers de chauffeurs de taxi. L’objectif de la présente étude est donc d'étudier les différences entre les différents groupes de conducteurs professionnels et non-professionnels en termes de réactions de stress, des nuisances sonores et d’implication dans la production des accidents de la voie publique (AVP). L’étude est de type transversal descriptif, réalisée au moyen d’un questionnaire et de tests neuropsychologiques, auprès 120 conducteurs au Maroc. Le stress a été évalué à l’aide de l’échelle de Stress Perçu (PSS) et le Test Résistance au Stress (TRS). Selon le PSS, les deux tiers (63.33 %) des chauffeurs de taxi pouvaient être considérés comme stressés. Chez ces chauffeurs de taxi, les composantes spécifiques les plus importantes sont les troubles de l’humeur, les troubles de sommeil, la pression de temps, l’ennui dans le travail, la sensation du stress et la fatigue à la fin de la conduite. Ainsi, 65 % des chauffeurs prennent une pause après 5 à 6 h de travail. D’après le Test Résistance au Stress, la population des chauffeurs de taxi est plus homogène mais offre une résistance au stress un peu plus faible que les conducteurs non-professionnels. Cette étude apporte un éclairage nouveau à la compréhension du stress au travail en utilisant des nouvelles méthodes de mesure et d’évaluations telles que le TRS. Elle invite tous les intervenants du domaine de la sécurité routière et de la santé publique à intervenir afin de réduire ou d’éliminer les AVP.

Estimation of Hydrodynamic Parameters of Soils in the Unsaturated Zone of Allada Plateau By Scaling Infiltration Equation and Beerkan Methods

Soclo W. P., Gbaguidi T. B., Igue A. M., Agbossou E.

Abstract:
The study of the effect of the variability of hydrodynamic parameters of soils in the unsaturated zone on flux requires the prior accurate estimate of hydrodynamic parameters. At local scale, traditional methods of physical and hydrodynamic characterization of soils are very accurate and efficient to describe the transfer of water in the soil. Just only the hydrodynamic properties of the soil are sufficiently well known. At large scale against, these methods have their limitations. They prove in fact, often time consuming, and larger areas become difficult to be characterized at hydrodynamic point of view.
For parameterization of the main soils of the Allada plateau consists of Haplic Acrisols, Umbric Fluvisols and Ferric Acrisols, we adopted a simplified method, easy to implement and much less time and equipment consuming. This is an experimental method called Beerkan method which relies on the knowledge of the particle-size distribution of the soil, its dry density, simplified infiltration tests using cylinders and scaling models of infiltration equations used as references. This study describes the experimental protocol and method of analysis which is applied to the estimation of parameters from the retention curve models, hydraulic conductivity and infiltration equation describing the hydrodynamic properties of soils of the unsaturated zone. The parameters of two orders are the hydrodynamic shape parameters and scale parameters.
The shape parameters related to the soil texture are derived from particle-size data analysis. The scale or normalization parameters depend on soil structure. They are obtained by inverse modeling and optimization from the infiltration tests. The concept of sorptivity and non-dimensional equations of the infiltration are the theoretical bases of this study. The results from the formalism for infiltration mono- and three-dimensional of Braud study (2005) are used. The relevance of the method has been shown from in situ and laboratory measured data on the main soils of the study area aforementioned. To adjust the observations to models, we adopted a simple optimization method applied to two boundary models, the Green & Ampt (1911) and Talsma & Parlange (1972) models. At the optimization step, two (02) fitting programs written in R language have allowed one to optimize shape parameters and the other the scale parameters. Fitting results of some Haplic Acrisols and Ferric Acrisols are satisfactory with the GA model contrary to the TP model that has not reproduced well the hydrodynamic behavior of soils of the study area. The fitting error RMSE of all the soil is less than 15%. But model and data curves are not well fitted excepting ferric Acrisols of SOCII1_50 site.
