Les hernies diaphragmatiques post-traumatiques se définissent comme le passage de viscères abdominaux dans le thorax à travers une brèche diaphragmatique post-traumatique. Elles constituent une pathologie rare. Elles peuvent être découvertes immédiatement au cours de la phase aiguë de l’accident ou très tardivement. Le but de notre étude est de définir les caractéristiques épidémiologiques, cliniques et thérapeutiques des patients ayant des hernies diaphragmatiques post-traumatiques admis dans le service de chirurgie générale du CHU Mohammed VI de Marrakech, ainsi que de discuter les étapes de la prise en charge de cette pathologie. Nous avons mené une étude rétrospective portant sur 16 hernies diaphragmatiques post-traumatiques colligées au service de chirurgie générale de CHU Mohammed VI de Marrakech, sur une période de 5 ans, du 16 octobre 2004 au 04 avril 2009. Au cours de ce travail, nous avons recueilli lesdonnées épidémiologiques, cliniques, thérapeutiques et évolutives à partir des dossiers médicaux des malades, par le remplissage d’une fiche d’exploitation. Les patients étaient tous de sexe masculin. Les âges extrêmes se situaient entre 04 et 106 ans avec une moyenne d’âge de 48 ans. La cause principale des hernies diaphragmatiques était les accidents de la voie publique (62,5%). La lésion diaphragmatique a intéressé surtout la coupole diaphragmatique gauche (87,5%) avec une rupture centrale chez 2 malades (12,5%). On n’a pas observé de rupture droite ni bilatérale. La clinique était peu évocatrice. La radiographie thoracique, élément essentiel du diagnostic, a permis de mettre en évidence la migration des viscères abdominaux en intra thoracique. En cas de doute, la tomodensitométrie a permis de confirmer le diagnostic. La rupture du diaphragme est une indication opératoire afin d’éviter les complications cardio-pulmonaires et digestives. Le choix entre voie abdominale et voie thoracique est conditionné par l’ancienneté de la rupture et le bilan lésionnel. La chirurgie vidéo-assistée permet à la fois de poser le diagnostic et de traiter les lésions retrouvées. Le pronostic est favorable et les complications sont rares. Il ressort de cette étude que l’éventualité d’une hernie diaphragmatique doit être systématiquement présente à l’esprit en cas de traumatisme thoraco-abdominal fermé violent ou en cas de plaie basithoracique par arme blanche ou arme à feu et que parmi les étiologies de l’occlusion intestinale, il faut penser à l’étranglement d’une hernie diaphragmatique surtout en cas d’antécédent de traumatisme thoraco-abdominal.

Means of presenting the Qur'anic text enjoy everlasting efforts to develop and meet the greatness and high status the holy Qur'an maintains. Consequently, this study aims at shedding light on the virtual relationship between the general concept of the Qur'anic mapping techniques and some of the resulting theories of linguistics on the one hand, and between the general concept of the Qur'anic mapping techniques and the theory of Multiple intelligences, on the other hand. The concept of the Qur'anic mapping is to facilitate meaning conveyance, embody concepts, and re-present the Qur'anic discourse in an understandable and comprehensible manner. Therefore, thinking of how the Qur'anic reader will absorb the new representation of the Qur'anic discourse, was a main issue in the Qur'anic mapping process. The resulting linguistic phenomena and the reflected relationship between the Qur'anic maps and the theory of Multiple intelligences were discussed in a detailed manner. The researcher utilizes XMind 7 (v3.6.0.R-201511090408) software in the designing of the Qur'anic maps. The Qur'anic maps take a hybrid design of concept maps and mind maps with the original Arabic Qur'anic text and the English translation of its meanings manipulated. The current study introduces itself as a foundation for a newer domain of research based on a decent association between Qur'anic exegesis and its topical classification, concept mapping, the various theories of linguistics, and the theory of Multiple Intelligences. The study also provides an opportunity for other studies to explore more linguistic theories and other observations regarding Gardner’s theory of Multiple Intelligences not mentioned in this study.

An experimental investigation was conducted to quantify the permeability reduction caused by enhanced biological growth in a porous media. Studies were conducted using columns packed with sand of three different sizes (0.2, 0.3, and 0.4 mm). Phenol was used as a growth substrate. The study involved three distinct Phases with three different concentrations of phenol (15, 50 and 100gm/l). Variations in piezometric head, substrate concentration, and biomass measured as volatile solids, were monitored in space and time. The reductions in permeability were found to be 78% for the coarse, 93% for medium size, and 93.7% for fine sand in Phase-I; Similarly in Phase-II, the reductions were 88.4% for coarse sand, and 94.6% for medium size sand. Finally, in Phase-III, the reductions were 95.5% for medium size, and 96.8% for fine sand. For aerobic sand media, volatile solids can be described as a function of influent substrate concentration respectively. The modified Kozeni-Carman equation was used to estimate the thickness of biological film, knowing the biofilm affected permeability. The estimated values of the film thickness varied from 0.06 mm to 0.09 mm. A good correlation was observed between porosity and biofilm thickness in low range values of thickness.

Preeclampsia (PE) has a serious impact for both mother and foetus . with an increase in cases every year. This is a prospective descriptive hospital based study involving 105 women (60 cases &45 control) delivered at Wad Medani Obstetrics’ & Gynecology Teaching Hospital between Jan. 2010 & April 2012. Of these 25 % were primigravidae & 75% were multigravidae. The test cases showed high blood pressure, albuminuria & lower limb edema. The main aim was to look for histological changes in preeclampsia placenta using routine histopathology stains E/H. The histopathological features attributed to preeclampsia in hematoxylin and eosin stained placental sections were per villous fibrin, villous arteriopathy& per villous ischemia. There was statistically significant decrease in placental weight and birth weight in preeclampsia group compared to control group. The study concluded that PE has a serious impact on both mother & foetus in Gezira Estate and without proper treatment it may lead to aharmful outcome both to the mother and to the fetus & it may needed to terminate the pregnancy to save the mother life .So we recommended more effort should be done regarding folloup and proper timely management for women during antenatal period.

The new impairment requirements stipulated by IFRS 9 (the Standard) represent a true challenge for the banking industry in terms of implementation effort, cost and time. The Standard was introduced as a direct response to address the banking sector’s weaknesses exposed by the recent financial crisis, which resulted in a delayed recognition of credit losses and accordingly huge losses borne by banks internationally. The Standard advocates a forward-looking impairment methodology for the calculation of Expected Credit Loss (ECL) on all portfolios held by financial institutions so as to build adequate provisions right upon initiation, even before any signs of actual impairment exist, based on holistic and forward-looking credit information. The institution must then track specific indicators of significant increase in credit risk and build provisions over the lifetime of those exposures which show signs of credit deterioration over time. IFRS 9 impairment requirements were applied by Lebanese banks in line with the Central Bank of Lebanon (the Regulator or BDL) requirements through issued guidance. One major implementation issue is the treatment of Sovereign exposures, which remains an unaddressed area by the current local guidance and a top item on the agenda of many Risk Managers. The present work intends to explore the available methodologies for computing ECL on the Sovereign portfolio and to propose an analytical framework for understanding and quantifying Sovereign credit risk within the Lebanese context. By reviewing the available market approaches adopted by other developed and developing countries along with those studied in the Sovereign risk literature, the research assesses the resulting approaches against Standard requirements and proposes potential options for consideration within the Lebanese context.
