Generic Reword Model of Partially Observed Markov decision processes (POMDP) for pattern detection

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

Fatal intoxication caused by the application of the multiple transdermals patchs of fentanyl

Fentanyl (N-phenyl-N-(1-2-phenylethyl-4-piperidyl)propanamide) is a potent synthetic narcotic analgesic. He has an analgesic effect 100 timesgreater than that of morphine. The use of transdermal fentanyl delivrery systems has increased over recent years especially in patients withchronic pain who are already treated with high doses of morphine or it is derivate. However, many cases of fentanyl intoxication through a varietyof transderrmal systems have been reported. This paper reports a fatality due to excessive administered Fentanyl Sandoz® Matrix 50ìg/htransdermal therapeutic systems

Leiomyoblastome gastrique: à propos de trois cas

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

Assessment of fatty acids profile, oil yield and tocopherol content of four Almond cultivars grown in Eastern Morocco

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

Efecto del envejecimiento acelerado sobre la composición lipídica de semillas de dos variedades de trigo blando de Marruecos

The lipid composition of the seeds from two soft wheat varieties (Triticum aestivum, cv. Marchouche and Mahdia) were analyzed before and after accelerated aging. Eight days of accelerated aging resulted in a total inhibition of seed germinability as well as a decrease in their total and especially unsaturated fatty acid contents. Oleic and linoleic acid contents decreased particularly in the phosphatidylcholine of the seeds from both varieties. The proportion of polar lipids also decreased after aging as compared to neutral lipids: a 5.8% and 7.2% decrease in polar lipids was e observed in Mahdia and Marchouche cultivars, respectively. In the neutral lipids of the seeds from the Marchouche variety, the percentage of free fatty acids increased whereas the triacylglycerols decreased. After aging, the fatty acid compositions of all lipid classes were modified in the same manner as total fatty acid compositions. Among polar lipids, phospholipid proportions were particularly small, especially the phosphatidylcholine percentages with an 18.1% and 19.1% decrease in Mahdia and Marchouche varieties, respectively. In contrast, MGDG percentages increased, especially in the seeds from the Marchouche variety. A 15.5% increase was noticed when compared with seeds which were not aged. At the same time, the DGDG percentage showed a 16.6% decrease after accelerated aging of the seeds from the Marchouche variety. From these results we concluded that the lipid content decrease observed in seeds after accelerated aging could be linked to a loss in the germination and vigor of wheat seeds.La composición lipídica de semillas de dos variedades de trigo blando (Triticum aestivum, cv. Marchouche and Mahdia) fueron analizadas antes y después del envejecimiento acelerado. Ocho días de envejecimiento acelerado provoco una inhibición total de la geminabilidad, así como un descenso en el contenido total de ácidos grasos, en especial de los ácidos grasos insaturados. Los contenidos del ácido oleico y linoleico disminuyeron particularmente, en la fosfatidilcolina de las semillas de ambas variedades. La proporción de lípidos polares también decreció después del envejecimiento en comparación con los lípidos neutros: un descenso del 5.8% y 7.2% de los lípidos polares fueron observados en los cultivos de Mahdia y Marchouche, respectivamente. En los lípidos de las semillas de la variedad Marchouche, el porcentaje de ácidos grasos libres aumento, mientras que los triglicéridos decrecieron. Después del envejecimiento, la composición de los ácidos grasos de todas las clases de lípidos fue modificada de la misma manera que la composición de los ácidos grasos totales. Entre los lípidos polares, la proporción de fosfolípidos fue la que disminuyo principalmente, en especial el porcentaje de fosfatidilcolina: un 18.1% y 19.1% para las variedades Mahdia y Marchouche, respectivamente. Por otra parte, los porcentajes de MGDG aumentaron, en especial en las semillas de la variedad Marchouche: un 15.5% en comparación con las semillas no envejecidas. Al mismo tiempo, los porcentajes de DGDG mostraron un descenso del 16.6% después del envejecimiento acelerado de semillas de la variedad Marchouche. De todos estos resultados, se concluye que el descenso del contenido lipídico observado en semillas después del envejecimiento acelerado podría estar relacionado con una pérdida de germinación y de vigor de semillas de trigo
