Modélisation et simulation de l’effet des bras morts sur la conductivité électrique dans un réseau de percolation. Cas d’un matériau polymère isolant.

baghdad hadri , مباركي بن زيان

كلية العلوم التكنولوجية-جامعة عبد الحميد بن باديس مستغانم · الجزائر

The electrical conductivity of organic insulating materials has been investigated using several theoretical models combining the percolation approach. The dead ends of the infinite cluster do not contribute generally to the electrical conduction in the presence of a weak electric field. We show in the first part, referring to the percolation approach, that during the application of a high electric field; the dead ends decrease the electrical conductivity according to an exponential law with a negative exponent, in dependence to the energy distribution of the sites, the correlation length of the clusters, and the length of the dead ends. In the second part, we check by simulation the effects of these dead ends on the electrical conductivity.

التجربة الشعرية عند المتوكل طه

عادل محمد أبو عمشة, عبد المجيد عبد العزيز احمد حامد

كلية الدراسات العليا -جامعة النجاح الوطنية · فلسطين

Abstract :After I completed this research, I can conclude the following results:First:The poet comes at the top of uprising poets generation and the last quarter of the past century in Palestine , and he has recorded a distinguished continuation and excessive presence and production.Second:several factors has elaborated in shaping the poet innovation and characteristic under both : general, and special environments. He was raised in a house of literature , besides, he has a valuable position socially , But, in the general view, he moved between different positions and experiences that participated in acknowledging him with wide net of literature innovators and their products.Third:The national aspect is the main concept , and the Arabic language is the most important feature of the poet . Since ,the parts of the home, and the strength of the revolution are extended in the poetry , such as , reciting with the identity and the land and up to criticizing the political aspect, but by being far from insults. Also the poet expressed his fears and negative attitudes to words the peace process with the Zionist enemy.Fourth:he illustrated the movement and the impulse of his people by viewing a vital picture about life at death through giving and my retires, and he went deeply to show the loosing enemy from the inner of the occupier.Fifth:the concept of the literacy in the poet work represented an extension to the movement of" prisons literature" , where he produce more than two group of poems under the excessive heat of AL- Naqab- .'"il,. The poet introduced the picture of the Jail in an abs tract and physical manners.But, the poet didn't show the picture of the cruel punishment that was practiced by the occupier under arresting camps and prisons . He has illustrated the view of the prisoner with high challenge , and with continued giving , and he has drawn a picture of hope with has been rooted from the heart of the suffering and the tragedy.Sixth:The picture of the Palestinian woman seemed a bigous, where it was between the traditional and negative view of the woman . It is that picture, which shows woman as the one who gives birth, and charge man with tender.But in the positive view, he showed the woman as a complete human being who stick with the man side by side in the battle of the people. Also poetry viewed the woman as the child, wife, prisoners, and revolution list.Seventh:The pot has taken from the humane traditional springs , such as, the religious, historical, popular aspects. He has used this great perspectives in building the modem picture through this environment and culture. The holy verses and the poetry expressions were mixed , and fur the more , the Christian feature of peace, and what the cross symbolize from suffering and tragedy were included too . The poet has employed the historical cultural dimension with the related surroundings , by describing his to racial characters and events . Also , he didn't ignore the people effect in supporting the above picture, and he has affirmed the national identification giving , and increased the extent of belonging to this identity and land.Eighth:The poetry picture is the maximum of innovation in the poetry expressions . And so, the poet has filled the expressions with pictures which enriched the invention process as an effort that is a way from being direct or related only to the surface .The fore , the poet, has contributed to the building of the picture by exchanging awareness, and the signals of sense, and the direct description, and all this was in addition to the compound picture that was distinguished by being built in accordance to the size of the subject , such as the experience of arresting and the peace process . The poet didn't ignore the universe , total ,picture which he has built through the drama, reality , and crosse section building in a manners that serve in introducing and innovation.Ninth:The poet has worked hard in choosing his terms and in retuning his language to reach the Arabic language . There is no doubt, that the Palestinian poet is distinguished for his rich Arabian language . and the vocabulary of poetry, so, he has use the nominative arid verb sentences in an order that suits the situation . He has use some phenomena in order to integrate his poem, such as : repetition, opposites, synonyms, but he fell in some mistakes that hurt few his expressions.Tenth:The poetry of AL- Motawikil Taha is rich with good music and good elements of music which seem to proceed horizontally to give life to the expression. With such ability, he maintained a medium position between the origins of poetry " AL- orood " and the rhythmic expressions that are rich with music, and those imaginary line of in eternal music, and with what it can produce as a deep norm , and it affects by repetition , parallel rhythms, circling, synonyms , matching, and the mutual commas , and his effort to disperse the common shape by maintaining the general from , specially by using free modem poetry that refers to the type of the verb which is called " tafeela ". In all of his poetry poems.Eleventh:The experience of the poet witnessed the development and continuous improvement through every poem publication , and this is represented in Oslo phase which is an important turn in his experience passage in the shape and in the essence , in order for the poet to bring to us the viewing of stones , ignition of tires , and up to the oppression of the selfish class and to portray the picture of attendance , and absence and the reasonable and the un reasonable in the peace consequences and amplifications with the tendency to words the culture, historical features , and the sky expressions in order to introduce events , and characters.

In this study, the failure rate of different types of bleed air control valves for the Boeing 737 aircraft is modeled. Two approaches are utilized to perform this work. In the first approach, Weibull model, in which different parameters are utilized and tested, is used. In the second one, a common type of the Artificial Neural Network (ANN) modeling is used. A Feed-forward back-propagation algorithm is implemented to train the network. Subsequently, the optimum number of neurons and layers that give the best result compared to the actual data are determined. Finally, the outputs from both models are compared against the actual data. The final results show a high level of accuracy of the ANN's predictions compared to the more traditional Weibull modeling. The developed verified model lends itself to applications that extend from scheduling replacements operations of these valves, to developing plans for inventory management in any aviation engines maintenance facility.

Les habitudes alimentaires ont changé significativement avec apparition de la nutrition déséquilibrée. L’hypercholestérolémie et l’hyperglycémie sont des troubles métaboliques qui peuvent être le résultat d’un déséquilibre alimentaire.L’hypercholestérolémie est l’un des principaux facteurs de risques des maladies cardiovasculaires et elle peut provoquer l’athérosclérose. L’hyperglycémie provoque nombreuses complications qui touchent plusieurs organes (les yeux, les reins, le coeur…). Donc le traitement de l’hypercholestérolémie et de l’hyperglycémie est une stratégie de prévention des autres pathologies plus graves. Plusieurs plantes et substances d’origine végétale sont appariées d'un effet considérable sur la cholestérolémie et la glycémie.Dans cette étude théorique, nous avons essayé d'étudier l’effet de la poudre de caroube sur les paramètres biochimiques plus précisément sur les paramètres lipidiques et glucidique.Les données résultant de notre recherche bibliographique suggèrent que la poudre de caroube présente plusieurs effets thérapeutiques grâce à ses composants (sucres, polyphénols, fibres et protéines) : hypocholestérolémiant, antidiabétique, antiprolératif et gastro-protecteur. Ainsi, les analyses biochimiques sanguines montrent aussi que la poudre de caroube peut empêcher les troubles métaboliques conduisant aux complications cardiovasculaires, hépatiques et rénales. De plus la caroube est susceptible d’être proposée en tant qu’additif alimentaire pour protéger contre les dommages de stress oxydatif.

كلية علوم الطبيعة والحياة-جامعة ابن خلدون – تيارت · الجزائر

La piroplasmose bovine est une maladie transmise par les tiques, qui se propage dans le monde entier et entraîne des pertes économiques importantes. L’objectif de la présente étude était de détermines quelques facteurs de risques des piroplasmoses bovines à travers un questionnaires destinée aux éleveurs de la wilaya de Tiaret. Un questionnaire distribue aux éleveurs composés de 13 questions au total. Les élevages ont été visités durant le mois de Février jusqu’au Mai 2023. Au total, 30 éleveurs nous ont répondu. D’après la présente étude, on a constaté que le mode d’élevage semi intensif qui est le plus fréquent avec une pourcentage de 60 %. En plus, la plupart des répondants à l’enquête réalisaient de mouvements d’animaux (achat ou prêt d’animaux) avec un taux de 60 %. On a constaté que 77 % des animaux étaient infestés par les tiques cette année, mais le reste non pas infesté par les tiques avec une pourcentage de 23 %. La présence de tiques est maximale aux saisons chaudes avec un rapport de 83 % ; (mois de Mai, juin et juillet) et d’une façon moindre aux saison froid. Selon les réponses obtenues durant notre enquête 44 % des éleveurs montrent que la mamelle c’est l’organe le plus infesté par les tiques. L’apparition des signes cliniques est maximale aux saisons estivales (été) avec un taux de 63 %. Tandis que, le taux est minimal en hiver et en automne, 7% et 3% respectivement. La plupart des propriétaires de bétail dans notre ou nos régions d'étude du Tiaret, utilisant deux produits pour la lutte contre les tiques qui sont : Sébacil et Bayticol avec un pourcentage de 59% et 41 % respectivement. La lutte contre les piroplasmoses bovines en Algérie nécessite dans un premier temps de mettre en place une enquête de séroprévalence afin d’évaluer la situation de la theileriose et de la babésiose bovine dans les élevages. Cette enquête permettra dans un deuxième temps de sélectionner les mesures adaptées à réaliser pour diminuer l’impact de ces maladies sur les bovins.
