    Research-based on deep reinforcement learning and stochastic modelization for bottleneck phenomenon optimization is the motivation for this development, by using big data technology and IoT-based sensors. In this paper we propose a generic representation of bottleneck phenomenon who narrows (limit) the possible actions in the observed field, such as the impact of the dangerous epidemics on human activity, economic, social and many other areas, which disturb the related schedule process, where the activity threshold must be included in an interval of actions in order to not enter a bottleneck phenomenon. On the other hand, a powerful reinforcement learning model, who handle tough situations that approach real-world complexity, in this level the data of the previous level well allow a better new action that may yield higher rewards in the next transitions, as well as the precise representation of the reward during the studied situation level, allows more wisdom for the future examination

    Les conduites addictives en anesthésie réanimation: à propos d’un cas

    L’anesthésie et la réanimation sont des métiers difficiles, faits de contraintes et de stress. En milieu anesthésique, des agents toxicomanogènes sont à la disposition des praticiens pour leur usage professionnel. L'exposition quotidienne, la facilité d'acquisition et d'utilisation de ces agents est un danger aux médecins et infirmiers, susceptibles de développer une toxicomanie. L'addiction ou toxicomanie aux agents anesthésiques ne représente qu'une partie du problème des dépendances chimiques qui incluent, les drogues licites que sont le tabac et l'alcool, mais aussi d'autres agents de la pharmacopée comme les antidépresseurs et les sédatifs. Nous rapportons le cas d'un infirmier anesthésiste, ayant des antécédents psychiatriques, toxicomane, admis au service d'accueil des urgences de l’hôpital militaire Moulay Ismail de Meknés dans un tableau de choc hémorragique compliquant un faux anévrysme rompu de l’artère fémorale commune droite.Key words: Addiction, toxicomanie, anesthésie, Maro

    Leiomyoblastome gastrique: à propos de trois cas

    Get PDF
    Le leiomyoblastome gastrique est une tumeur musculaire rare qui touche essentiellement l'adulte. Son développement est souvent exogastrique.Le diagnostic positif repose sur l'histologie et le traitement est basé sur la chirurgie. Nous rapportons trois cas de leiomyoblastome gastrique colligés dans le service de chirurgie générale au 5ème Hôpital Militaire. L'âge  moyen des patients est de 47 ans; le motif de consultation était représenté par une hémorragie digestive et l'imagerie médicale a posé le diagnostic de masse tumorale dans tous les cas. Le traitement chirurgicalconsistait en une gastrectomie partielle et le compte rendu   anatomopathologique a confirmé le leiomyoblastome gastrique dans les trois cas. Le siège de la tumeur a été posé par la fibroscopie oeso  gastroduodénale, le traitement était chirurgical et les suites post  opératoires étaient simples avec un contrôle par des fibroscopies  répétitives sans aucun signe de récidive. Le leiomyoblastome gastrique est une tumeur rare. L'écho endoscopie joue un rôle primordial dans le  diagnostic positif ainsi que dans l'évaluation de l'extension pariétale de ces tumeurs. Le traitement est essentiellement chirurgical

    The most cultivated varieties of almond in eastern Morocco: (Beldi (B), a local ecotype, Marcona (M) from Spain, Ferragnes-Ferraduel (F-F) and Fournat de Breznaud (FNB) from France), were studied during three consecutive crop years in order to evaluate variations in kernel oil yield, Fatty acid (FA) profile and physicochemical properties. For this purpose, extraction of almond oils was carried out by mechanical press. The yield of varieties B, M, (F-F) and FNB ranged between 50.68%- 54.33%, 41.46%- 52.59%, 47.70%-52.39% and 51.66%-56.10%, respectively. Oleic, linoleic and palmitic acids are the major fatty acids (FA) ranging between 57.54%- 72.90%, 17.80%- 29.81% and 6.50%-8.48%, respectively. Results showed a noticeable effect (P<0.001) of variety on Total phenolic content (TPC), oxidative stability and α-, β-, γ-, δ-tocopherol isomers; however, acidity and peroxide index, were affected with a lower manner by "variety" factor. In addition, all the analyzed parameters were highly (P<0.001) affected by climatic conditions of the crop year. In addition, the highest variations for the analyzed almond oils were recorded for their contents on α-tocopherol, γ-tocopherol, oleic and linoleic acids. According to the observed results, the couple Ferragnes-Ferraduel seems to produce stable and high quality almond oil compared to the other varieties

    Variability in almond oil chemical traits from traditional cultivars from eastern Morocco

    In Morocco, cultivation of almond tree (Prunus amygdalus L.) constitutes the second most important plantation of fruit trees after olive growing. It is mostly cultivated in two regions, « Taza, Al Houceima Taounate » in the north and « Souss Massa Draa » in the south. Almond genetic resources (Marcoma, Fournat, Ferragnes/Ferraduel and Beldi), cultivated in eastern Morocco were studied during two consecutive crop years in order to evaluate variations in kernel oil yield, fatty acid profiles, oleic /linoleic (O/L) ratio and almond oils oxydative stability (OSI,evaluated by rancimat tests) in comparison to monovarietal olive oils. Almond kernel total oil (AO), Oleic acid (C18:1), Linoleic acid (C18:2), O/L-ratio, and tocopherol contents range between: 48 - 62% for kernel total oil; 65- 77.5% for C18:1; 17- 25% for C18:2; 2.5-4 for O/L ratio and 370 - 675 μg/g oil for tocopherols, respectively. We conclude that the genotype is the main variability source for all these chemical traits of AOs. Results obtained from Ferragnes/Ferraduel may be of interest for almond breeding focused to improve kernel oil yield and fatty acid profile. Besides, tocopherols contents of AOs seem to be the most important contributor for their stability to oxidation, even though compared to monovarietal olive oils, stability of AOs were very low and OSI value range between 20-27 hours. This fragility of AOs is due to their high content of unsaturated fatty acid which not allows their use for cooking or storage for long period. However, almond oils could have many applications in the food industry as in cosmeti
