A Study on the Relationship Between Democracy and Corruption in Mena Countries by Using DGMM Model

The purpose of this study is to investigate the relationship between democracy and corruption using a Dynamic Generalized Method of Moments (DGMM) during the period 1984-2013 for 13 MENA countries, namely Algeria, Bahrain, Egypt, Iraq, Iran, Kuwait, Lebanon, Morocco, Qatar, Saudi Arabia, Tunisia, Turkey and United Arab Emirates.Our results captured the GDP per capita as the  feeding corruption factor in MENA countries in a way that a rise of one percent of per capita GDP leads  corruption to rise by about 0.73 particularly in MENA net oil and gas exporting countries except for United Arab Emirates (See Omgba (2015); Haber and Menaldo (2011). In this context, the richest oil exporting countries have not been able to decrease their corruption level, (See Jetter (2015), Rachdi and Saidi (2014). Conversely, the magnitude of impact for non-oil producing countries happen to be less related to corruption over the last decade compared to the two early decades. Finally, our findings present a positive and a significant association between democracy and corruption; the influence of positive feedback is around 0.5 points. According to this estimation, lower democratization process in MENA countries is highly influenced by high levels of corruption.

The Study of Inflation in Algeria: An ARDL Testing Approach

It is recognized that inflation is one of most misunderstood economic phenomena. Indeed, it is a persistent increase in general price level  both of goods and services in an economy over a period of time, which affect necessarily the purchasing power or a loss in the real value of the money. Therefore, in many countries, controlling inflation has been a high priority, especially those with small open economies since the early 1970s when oil prices soared to record high levels.In Algeria, inflation appears as a first challenge for recent economic performance. This study examines the main determinants of inflation in Algeria using the ARDL model during the period 1980-2016. In this context, this paper focuses on the major sources to explain inflation trend in Algeria (imports price, oil price and money stock, government expenditure and effective nominal exchange rates of the Algerian Dinar). However, our results based on ARDL model establish that a stable long-run relationship exists between inflation and its determinants. Thus, in the short run, only external factors (imports price, oil price and effective and nominal exchange rates) impact inflation in Algeria. Consequently, we may infer, as far as the impact on inflation is concerned, that fiscal and monetary policies cannot on their own be statistically significant.

The emergence of Arab-Islamic sciences and the "politics of truth" in the classical era of Islam

تهدف هذه الدراسة الى الوقوف على المنشأ التاريخي للعلوم العربية الإسلامية والشروط التي حددت " صحة العلم" و " سياسة الحقيقة" في إسلام العصر الكلاسيكي، من أجل ذلك تحددت هذه الدراسة بسؤالين مركزيين، سؤال تاريخي، يرتبط بالمنشأ والتطور، وآخر يتعلق بشروط الصحة ومعالم سياسة الحقيقة. من أجل ذلك أخضعت هذه الدراسة لمنظور تعاقبي-دياكروني-يتعلق بالمنشأ والتطور وآخر تزامني -سانكروني- يتعلق بثوابت الممارسة العلمية في إسلام العصر الكلاسيكي.This article aims to emphasize in which historical context the Arabic sciences has emerged in the classical period of Islam, and witch policy of truth has undetermined and structured the production of knowledge in Islam. We have adopted a double approach, one is dicrotic view to describe the evolutionary process of Islamic sciences and synchronized view to discover the structure of the production of sciences in the classic period of Islam

Valeurs nutritives et toxicité du foenicululm vulgare miller

Food values and toxicity of the foenicululm vulgare millerFoeniculum vulagre Mill. plant aromatic, spontaneous and wides pread in algeria is used by the population for its medicinal virtues. Our samples, coming from the Algerian west, showed that the contents of the principal compounds resulting from the primary metabolism and for each part of the plant (soed, stem and roots) are interesting for proteins (17,5 %) and lipids (12 %) and relatively  weak for glucids (13 %). The presence of toxic components coming from the secondary metabolism in particular the coumarins and tanins, made up recognized like inhibiting the digestibility of proteins, influential on the evolution of the ponderal mass of the animal (rat "Wistar"). The saponosides, flavonoïdes, sterols and steroïdes, tanins, coumarins, alcaloïdes, anthracenosides, anthocyanosides and emodols with little or no presence, have only little influence on the digestibility qualities of the plant. The output of 2,7 % in essential oil from the flowering plant is interesting and is in conformity with those obtained by the literature

Numerical study of adsorption for fluids mixture near critical point in a micro-cavity

International audienceThe main goal of this paper is the study of adsorption and mass transfer in a binary mixture near the solvent’s critical point. The physical model consists of a dilute mixture (naphthalene-supercritical CO2) enclosed in a rectangular cavity of height of order 1 mm with a hot and adsorbent plate at the bottom wall. To benefit from the supercritical fluid specific properties and optimize thermodynamics conditions allowing a better adsorption with a good mass transfer, effects of the critical point proximity and heating are the object of several numerical simulations in the present work. The mathematical model used is based on the solution of the Navier-Stokes equations, coupled with energy and mass diffusion equations with the Peng-Robinson equation of state. In order to reduce computational costs, these equations are solved in the low Mach approximation. The velocity field, perturbation of the mass fraction as well as the temporal evolution of the average Sherwood number are presented for different heatings. The confinement effect is also analysed. The results show that in the mixture critical point neighborhood and for a very high heated wall, the homogeneous adsorption of the solute is obtained. Among other key results, we cite that, under the same optimized conditions, the mass transfer on the adsorbent plate is better.L'objectif principal de cet article est l'étude d'une réaction d'adsorption et des transferts de masse associés dans un mélange binaire près du point critique du solvant. Le modèle physique consiste en un mélange dilué (naphtalène-CO2 supercritique) contenu dans une cavité rectangulaire d'une hauteur de l'ordre de 1 mm et présentant sur sa paroi inférieure une plaque chauffée et adsorbante. Pour tirer parti des propriétés spécifiques du fluide supercritique et optimiser les conditions thermodynamiques permettant une meilleure adsorption avec un bon transfert de masse, les effets de la proximité du point critique et du chauffage font l'objet de plusieurs simulations numériques dans le présent travail. Le modèle mathématique utilisé est basé sur la résolution des équations de Navier-Stokes, couplées aux équations d'énergie et de diffusion des espèces ainsi qu'à l'équation d'état de Peng-Robinson. Afin de réduire les coûts de calcul, ces équations sont résolues dans le cadre de l'approximation à faible nombre de Mach. Le champ de vitesse, la perturbation de la fraction massique ainsi que l'évolution temporelle du nombre moyen de Sherwood sont présentés pour différents chauffages. L'effet de confinement est également analysé. Les résultats montrent que, dans le voisinage du point critique du mélange et pour un fort chauffage de la paroi, on obtient l'adsorption homogène du soluté.Parmi les autres résultats clés, citons que, dans les mêmes conditions optimisées, le transfert de masse sur la plaque adsorbante est meilleur

Giant Presternal Dermoid Cyst: An Adult Case

Epidermal cysts are more common above the shoulder and within the face and scalp. The authors report a case of giant presternal dermoid cyst in a 25 year old man. The case illustrates that dermoid cysts can appear in atypical location. Dermoid cysts should be considered in the differential diagnosis of midsternal lesions regardless of the size and imaging characteristics.Key Words: Dermoid cyst, Presternal chest wall, Thoracic surger

La place de la thoracoscopie dans la prise en charge des pathologies thoraciques: à propos de 104 cas

Introduction: La thoracoscopie est l'exploration endoscopique de la cavité pleurale, des organes avoisinants (diaphragme, péricarde, médiastin) et du poumon. Le but de ce travail se veut d'abord didactique ; décrivant la thoracoscopie, ses techniques ainsi que sa place dans la prise en charge de la pathologie thoracique (indications et perspectives thérapeutiques) et informatif en rapportant l'expérience de notre équipe. Méthodes: Il s'agit d'une étude rétrospective intéressant 104 thoracoscopies à visée diagnostique et/ou thérapeutique réalisées au service de chirurgie thoracique du Centre Hospitalier Universitaire Hassan II de Fès, sur une période de 04 ans (Août 2008-décembre 2012). Nous avonsexclu de notre étude les cas ayant bénéficié d'une médiastinoscopie ainsi que les cas ayant bénéficié d'une thoracoscopie dans le cadre des traumatismes fermés du thorax ou des plaies thoraciques. Résultats: L' âge moyen des patients est de 47 ans, avec des extrêmes allant de 18 à 80 ans, et une légère prédominance masculine à 54%.La thoracoscopie est d'ordre pleural chez 86 patients, pulmonaire chez 10 patients et médiastinale chez 8 patients. La thoracoscopie avait une indication à visée diagnostique chez 87 cas et thérapeutique chez 52 patients (talcage dans 45 cas, décortication pleuropulmonaire dans 2 cas, résection de kystepleuro-péricardique dans 2 cas, cure de pneumothorax dans 2 cas etune fenêtre péricardique). L'évolution post opératoire etait marquée par une amélioration clinico-radiologique chez 40 malades, 11 ont présenté une amélioration clinique seule, 6 ont présenté une persistance ou une récidive de l'épanchement. Conclusion: La thoracoscopie représente un réel gain en matière de diagnostic de certaines pathologies intra-thoraciques. Son intérêt thérapeutique limité doit être éventuellement étendu grâce à la chirurgie thoracique vidéo assistée, qui est une technique récente fiable avec une limitation de la durée d'hospitalisation et de la morbidité.Keywords: Biopsie, métastases, thoracoscopi
