Non-linear sound propagation is investigated computationally by simulating compressible time-developing mixing layers using the Large Eddy Simulation (LES) approach and solving the viscous Burgers Equation. The mixing layers are of convective Mach numbers of 0.4, 0.8 and 1.2. The LES results agree qualitatively with known flow behavior. Mach waves are observed in the near sound field of the sup...

Ce document s'inscrit dans le sous-projet 2 et la tâche 2.3 du projet WAVEMOD. A partir de la base de données de Crète, la dissymétrie des vagues et les paramètres statistiques d'ordre 3 sont étudiés. Outre la profondeur, l'influence sur ces statistiques du principe de mesure (Eulérien / Lagrangien / bouée) est analysée: • les distributions des hauteurs de crêtes, de creux ainsi que des hauteur...

Pendant Les annees dernieres la Pollution de l, athmosphere des salles d, Operation Par les anesthesiques volatils et Gazeux est bien etu­diee et la consequence Pathologique de cette Pollution est certaine; c, est Poruquois nous som­mes obliges de diminuer cette Pollution et em­pecher de se repandre ces agents dans les salles d, Operation. 

Background: infant mortality rate is one of the main health indicators for assessing the health system’s performance over the world. We aim to examine the socioeconomic and health system factors affect infant mortality in OPEC from 2004 to 2013. Methods: was used to examine the effects of some of the key explanatory factors (total fertility rate per women, GDP per capita (current US$), public h...

background access to appropriate and affordable healthcare is needed to achieve better health outcomes in africa. however, access to healthcare remains low, especially among the poor. in zambia, poor access exists despite the policy by the government to remove user fees in all primary healthcare facilities in the public sector. the paper has two main objectives: (i) to examine the factors assoc...

in this paper, we investigate the general fuzzy linear system of equations.  the  main aim of this paper is based on the embedding approach. we find the necessary and sufficient conditions for the existence of fuzzy solution of the mentioned systems.  finally, numerical examples are presented to more illustration of the proposed model.

BACKGROUND There is need for the Uganda Ministry of Health to understand predictors of primary health care pharmaceutical expenditure among districts in order to guide budget setting and to improve efficiency in allocation of the set budget among districts. METHODS Cross sectional, retrospective observational study using secondary data. The value of pharmaceuticals procured by primary health ...

We show that given a poset P and and a subposet Q, the integer points obtained by restricting linear extensions of P to Q can be explained via integer lattice points of a generalized permutohedron. Résumé. Nous montrons que, étant donné un poset P et un subposet Q, les points entiers obtenus en restreignant les extensions linéaires de P à Q peuvent être expliqués par les points entiers d’un per...
