BIRDS DIVERSITY OF RIPARIAN ECOSYSTEMS IN ARID REGIONS OF ALGERIA
As a riparian ecosystem, Oued K'sob is located in the arid region (El Hodna-M’Sila). The aim to assess the waterbird diversity and their habitat use in relation to environmental factors in this particular ecosystem. A regular survey of riparian avifauna was performed from February to May 2016. A total of 32 species representing 18 families and 8 orders were found through different stations. Environmental indicators showed the highest values at the Bou Khemissa 1 station. The bird population exhibits biogeographic heterogeneity, with the Palearctic region being the most represented. The high values of resident species (19 ether 38.77%). The polyphagies trophic category is the better represented with 43.75% of all species. The availability of food resources, the biology of the species, tranquility and aquatic vegetation are the main factors that control the distribution of birds in their habitat.

Epidemiological assessment of ectoparasite prevalence in the dromedary camel (Camelus dromedarius) in the Sahara Desert.
Dromedary camels Camelus dromedarius Linnaeus (Artiodactyla, Camelidae) are vital to the livelihoods of nomadic and pastoralist communities in the Sahara Desert. However, they are susceptible to ectoparasites, which can significantly impact their health and productivity, as well as their potential role in transmitting zoonotic diseases. This study aimed to investigate the prevalence, species composition and infestation levels of ectoparasites in dromedaries from different camel herds (CH) across northern Algeria’s Sahara Desert. Additionally, we assessed the effects of CH and camel age and sex on parasite loads and infestation patterns regarding the host’s affected body region. A total of 68 camels out of 135, randomly selected from four herds CH1–CH4, were surveyed for ectoparasites. Ectoparasites were counted, collected and identified in the laboratory. Pearson correlation tests were employed to analyse the relationship between parasite indices. Similarity analysis was conducted to compare ectoparasite species composition among the sampled CH. The over all infestation level of ectoparasites across the CH was 61.76% with 511 ectoparasite individuals identified. Significant regional variation in tick prevalence was observed: CH1 (88.24%), CH2 (64.71%), CH3 (58.82%) and CH4 (35.29%) (p < 0.001). The most prevalent ectoparasites were ticks, with four species identified: Hyalomma dromedarii Koch (Ixodida, Ixodidae) (45.21%), Hyalomma marginatum marginatum Koch (Ixodida, Ixodidae) (18%), Rhipicephalus sanguineus sensu lato Latreille (Ixodida, Ixodidae) (7.63%) and Ixodes ricinus Linnaeus (Ixodida, Ixodidae) (4.9%). In addition, one mite species Sarcoptes scabiei Linnaeus (Sarcoptiformes, Sarcoptidae), one flea species Ctenocephalides arabicus Jordan (Siphonaptera, Pulicidae) and one fly species Wohlfahrtia magnifica Schiner (Diptera, Sarcophagidae) were identified. Similarity analysis showed a 70% overlap in ectoparasite species composition between herds, suggesting common environmental and management-related risk factors. Overall, the abdomen exhibited the highest percentage of ectoparasites at 22.7%, followed by the neck and sternum (17.8%), and the anal and tail area (17.4%). Adults accounted for 86.1% of infestations, with notable contributions from the abdomen (17.0%) and neck/sternum (15.9%), while young camels made up only 13.9%. The high ectoparasite infestation level, particularly ticks, underscores the need for a comprehensive control plan, especially in herds managed under extensive or nomadic systems. Future research should focus on identifying risk factors and exploring ectoparasite control strategies to reduce the burden on camel health and prevent potential zoonotic disease transmission in the region.

Cross Sectional Survey on the Prevalence and Associated Risk Factors of Toxoplasma Infection in Pregnant Women in Biskra (Southeastern Algeria).
Toxoplasmosis, caused by Toxoplasma gondii, is a zoonotic disease with significant global public health implications. In Algeria, data on its epidemiology are scarce. This study aimed to assess for the first time the seroprevalence of toxoplasmosis and identify associated risk factors among pregnant women in Biskra governorate in southeastern of Algeria. A cross-sectional survey (October 2022–May 2023) involved 453 women. Data on socio-demographics characteristics, gynecological history, and lifestyle habits were collected via structured questionnaires. Plasma samples were analysed for IgG and IgM antibodies using ELISA techniques. Statistical analyses, including univariate and multivariate logistic regression, were performed to identify significant risk factors associated with seropositivity. The overall seroprevalence of toxoplasmosis was 30.02 %. Univariate analysis identified several significant associated risk factors, including a history of spontaneous abortion (OR = 3.897), having single spontaneous abortions (OR = 4.96), consumption of unpasteurized milk (OR = 1.789), and owning pets (OR = 1.593). Living in urban areas appeared to be a protective factor (OR = 0.60). Multivariate analysis further highlighted feeding raw meat to animals (AOR = 8.395) and having given birth to a malformed child (AOR = 6.718) as major risk factors. Additionally, fast food consumption (AOR = 2.07) and cats ownership (AOR =3.724) were also significantly associated with T. gondii seropositivity. The findings underscore the importance of implementig robust screening, prevention, and treatment strategies for toxoplasmosis, particularly among pregnant women. This study offers valuable epidemiological insights into toxoplasmosis in Algeria, addressing a critical knowledge gap.

Statistical analyses, including univariate and multivariate logistic regression, were performed to identify significant risk factors associated with seropositivity. The overall seroprevalence of toxoplasmosis was 30.02 %. Univariate analysis identified several significant associated risk factors, including a history of spontaneous abortion (OR = 3.897), having single spontaneous abortions (OR = 4.96), consumption of unpasteurized milk (OR = 1.789), and owning pets (OR = 1.593). Living in urban areas appeared to be a protective factor (OR = 0.60). Multivariate analysis further highlighted feeding raw meat to animals (AOR = 8.395) and having given birth to a malformed child (AOR = 6.718) as major risk factors. Additionally, fast food consumption (AOR = 2.07) and cats ownership (AOR =3.724) were also significantly associated with T. gondii seropositivity. The findings underscore the importance of implementig robust screening, prevention, and treatment strategies for toxoplasmosis, particularly among pregnant women. This study offers valuable epidemiological insights into toxoplasmosis in Algeria, addressing a critical knowledge gap.

Cross Sectional Survey on the Prevalence and Associated Risk Factors of Toxoplasma Infection in Pregnant Women in Biskra (Southeastern Algeria).
Toxoplasmosis, caused by Toxoplasma gondii, is a zoonotic disease with significant global public health implications. In Algeria, data on its epidemiology are scarce. This study aimed to assess for the first time the seroprevalence of toxoplasmosis and identify associated risk factors among pregnant women in Biskra governorate in southeastern of Algeria. A cross-sectional survey (October 2022–May 2023) involved 453 women. Data on socio-demographics characteristics, gynecological history, and lifestyle habits were collected via structured questionnaires. Plasma samples were analysed for IgG and IgM antibodies using ELISA techniques. Statistical analyses, including univariate and multivariate logistic regression, were performed to identify significant risk factors associated with seropositivity. The overall seroprevalence of toxoplasmosis was 30.02 %. Univariate analysis identified several significant associated risk factors, including a history of spontaneous abortion (OR = 3.897), having single spontaneous abortions (OR = 4.96), consumption of unpasteurized milk (OR = 1.789), and owning pets (OR = 1.593). Living in urban areas appeared to be a protective factor (OR = 0.60). Multivariate analysis further highlighted feeding raw meat to animals (AOR = 8.395) and having given birth to a malformed child (AOR = 6.718) as major risk factors. Additionally, fast food consumption (AOR = 2.07) and cats ownership (AOR =3.724) were also significantly associated with T. gondii seropositivity.

Tailoring Optoelectronic Characteristics of ZnxCd1-xS Alloys through Band Gap Modulation
Abstract: In this research, we examine the optical and dielectric characteristics of ZnxCd1-xS, a ternary alloy system with a zinc-blende crystal structure. Our analysis employs a pseudopotential model based on the virtual crystal approximation, which accounts for the effects of compositional disorder. Through our calculations, we investigate various aspects of the refractive index and determine the most suitable model. Additionally, we determine the high-frequency and static dielectric constants for the materials studied. Crucially, we explore the band gap energy of ZnxCd1-xS, which is a fundamental parameter influencing its optical and electronic properties. The ability to tune the band gap energy through compositional variation makes this alloy system particularly attractive for diverse optoelectronic applications, including solar cells, light-emitting diodes, and photodetectors. Our findings show good agreement with previously published results in the literature. These results provide valuable insights for the application of this data in optoelectronics and offer useful information for further research in this field, particularly in the context of band gap engineering for specific device requirements.

Elaboration et caractérisation d'un matériau composite à base de caoutchouc naturel renforcé par des fibres de verres, fibres végétales et hybrides
les composites à matrice élastomère renforcés par des fibres de verre et des fibres végétales représentent une classe émergente de matériaux hybrides, combinant des performances mécaniques et thermiques satisfaisantes à une empreinte environnementale réduite. L'intégration de fibres naturelles biodégradables dans une matrice polymère, souvent à base de caoutchouc, permet d'améliorer la légèreté, la flexibilité et la durabilité des composites, tout en réduisant les coûts de production et l'impact écologique. Le renforcement par des fibres de verre confère au matériau une rigidité et une résistance accrues, tandis que les fibres végétales (telles que le lin, le jute ou le sisal) apportent un caractère renouvelable et durable au système composite. Le choix des fibres, leur nature, leur orientation ainsi que leur compatibilité avec la matrice jouent un rôle déterminant dans les propriétés finales du matériau. Ces composites trouvent de nombreuses applications dans des secteurs variés tels que l'automobile, l'aéronautique, la construction et l'industrie du pneumatique, où la recherche de matériaux alliant performance et responsabilité environnementale devient prioritaire. Ainsi, le développement de ces matériaux multifonctionnels s’inscrit pleinement dans une démarche d’innovation durable, répondant aux exigences croissantes de l’industrie en matière de performances techniques, de légèreté et de respect de l’environnement. Keywords: Composite, luffa, Adhesion, Tensile strength, Alkaline treatment

Towards an African Breaking-free: Afro-futurism as a Call for Change in Octavia Butler's Dawn (1987) "
Abstract : The intersection between literary studies and scientific confrontations has always been a mediating factor in today’s world literature .The age of globalization , notwithstanding its apocalypse, has witnessed a quantum leap in digital literacy and genetic denaturalization. Considerably , the consent behind undertaking this research lies in the too-often reconfigured venture to broaden the scopes of literary texts while intermingling cross- sectional narrative techniques and innovative fields of interests including cybernetics , genetic engineering , informatics. In this respect , this scholastic endeavor sheds lights on how Octavia Butler’s Dawn (1987) as a speculative fiction work builds its plot and copes with Afro-futuristic visions to mirror the humanity’s soon-to-be fate as it appears as the installment of her ‘’Xenogenesis Trilogy ‘’ . The genre of Sci- Fi and speculative fiction, for researchers , is a complicated production to endow analysis .Thus, to critically analyze the abovementioned corpus and meet the requirements of the descriptive research approach , selected passages , quotes , characters and timelines were selected . However , to serve the essence of this attempt and ensure good quality research , reference to an amalgam of theories in multiple fields constitutes a key-takeaway solidification , these theories were open but not limited to Donna Haraway’s Cybrog Manifesto (1985) and Freidrich Nietzsche’s idea of Ubermensch in his book Thus Spoke Zarathustra (1883). The findings of this research show that the intersection between literature and science in Butler’s book consists of new debated topics and themes following the avant-garde in writing influenced by Aime Cesaire’s Negrtitude and the narrative techniques of postmodernity , a venture which lacks a genuine signature of contemporary literature stylistically but not thematically . it also echoes black existentialism and its deeply-rooted thirst to keep pace with change and progress while destabilizing the influence of whiteness over the other ethnicities . Keywords : Afrofuturism , engineering , fiction , postmodernity , Science

First report of Dactylogyrus fimbriphallus (El Gharbi, Birgi & Lambert, 1994) infecting Luciobarbus biscarensis (Boulenger, 1911) in Oued Tadmit River of Djelfa Governorate (Algeria).
This study aimed to determine the occurrence of dactylogyrid communities in Sahara barbel, Luciobarbus biscarensis (Boulenger, 1911), an endemic species to Algeria, according to season and host factors. A total of 78 samples of L. biscarensis were collected seasonally, over four seasons from 2023 to 2024, from Oued Tadmit River in Djelfa Governorate with the help of local fishermen. Thirty-three L. biscarensis were infected with one or more individuals of dactylogyrid parasites (42.31%), and a total of 306 individuals were recorded. All monogenean species collected from the gills of the host fish were identified based on the presence of the following morphometric characteristics: two pairs of anchors, dorsal bar, ventral bar, vaginal armament and copulatory tube. Only one Dactylogyrus species, Dactylogyrus fimbriphallus (El Gharbi, Birgi & Lambert, 1994), was found on the gills. The mean intensity and abundance were 9.27 ± 12.50 parasites per fish and 3.92 ± 9.28, respectively. The infection levels of D. fimbriphallus were also investigated in relation to length and sex of the host fish as well as seasons, and the differences in its prevalence, mean intensity and mean abundance were statistically evaluated. There were significant differences in prevalence, mean intensity and abundance values between seasons. The infestation rate was higher in female hosts than in males. The host fish represents a new host record for D. fimbriphallus and new insights into the geographical distribution and host range have been gained. This study highlights the need for further research on helminth parasites, particularly monogeneans, affecting Algerian freshwater fishes, given the limited existing data.

دراسة ميدانية لاسخدام اللغة الأم لتعليم اللغة الانجليزية
Effective communication is one of the aims of the foreign language learning/teaching process. However, in some cases, communication breaks down; learners fail to get the message sent either by the teacher or by their peers. Teachers try different strategies to improve communication in class involving as many learners as possible. In other words, they seek to promote classroom interaction. L1Translation could be one of the strategies used to enhance and facilitate communication. In recent years, much attention has been given by several researchers ( Leonardi, 2010) to the issue of mother tongue use and the revival of translation as an integral part in foreign language teaching in different parts of the world. The point that is worth raising, at this level, is that using translation in foreign language classes is a controversial issue and generally viewed with suspicion. Some consider it a useful pedagogical tool; however, others regard it as harmful.

Corrosion inhibition of bis-isoQuinolinium salts derivatives for mild steel A283 Grade C in sulfuric media: an experimental and theoretical investigation
This work examines the efficiency of four bis-isoQuinolinium compounds in preventing the corrosion of A283 Grade C steel in a 0.5 M H2SO4 solution. The performance of these corrosion inhibitors was examined at various concentrations using weight loss, electrochemical impedance spectroscopy, and potentiodynamic polarization. Using gravimetric weight loss, the efficiency (IE%) reached a high value of 97.32, 98.14, 97.94, and 98.14% when the concentration reached 5 mM of bis-isoQuinolinium salts EtiQuiBr, PriQuiBr, BuiQuiBr, and PniQuiBr, respectively. According to the different investigations, the bis-isoQuinolinium salts are mixed-type inhibitors with slight predominance of cathodic inhibition. The adsorption of all studied inhibitors on the metal surface of A283 Grade C mild steel followed the Langmuir adsorption isotherm and the inhibition efficiencies decreased with temperature. The thermodynamic parameters, such as Ea, Kads, and ΔG°ads were determined. The negative values of ΔG°ads suggested a favorable adsorption of all inhibitors on steel surface. The order of IE determined from experimental measurements is: EtiQuiBr < PriQuiBr < BuiQuiBr < PniQuiBr. Furthermore, microscopic surface analyses, such as SEM and AFM were used to characterize the surface morphology of the steel specimens. Moreover, the Density Functional Theory (DFT) calculations were performed to correlate the electronic molecular structure of the studied inhibitors with their inhibition efficiency. The tested compounds can be effectively used as corrosion inhibitors for steel in sulfuric acid and the findings of this work shed more light on the corrosion inhibition of steel by ammonium salts in acidic medium.

Valorization of biological studies of medicinal plant « thapsia garganica »
Thapsia garganica is a widespread species in Algeria, best known for the use of its roots in cooking and traditional medicine. This medicinal plant has been known since ancient times for its curative and preventive efficacy, it belongs to the apiaceae family. In our study we aimed to assess the evaluation of biological activities of this plant. We started this work with the methanolic extraction of all the components contained in the plant in order to obtain a crude extract, which we separated with different polar solvents “petroleum ether, chloroform, and ethyl acetate and n-butanol” The flavonoids were evaluated by the method of aluminum chlorides AlCl3, the content is estimated at 5.6009 mg EQ / g dry matter in the crude extract. The DPPH test has attracted a lot of attention due to its speed, sensitivity and reproducibility. The IC 50 of the different extracts are compared with the BHT standard. The IC50s in the order of antioxidant power were: petroleum ether (42,2938144 mg/ ml) > acetate ethyl (0,67893784mg / ml> BHT (0.0059 mg / ml). Depending on the results we have obtained, we can predict that flavonoids are first class antioxidant agents. Keywords: medicinal plants, antioxidant activity,DPPH.

Effets d’incorporation des rebuts de dattes et du lactosérum sur les performances de croissance et l’évolution corporelle des agneaux Rembi (Algérie)
Description du sujet. L’utilisation de sous-produits tels que le lactosérum et les déchets de dattes dans l’alimentation animale peut réduire les coûts de production sans affecter les performances du bétail. Objectifs. Ce travail vise à étudier les effets de l’incorporation de deux sous-produits agro-industriels, les rebuts de dattes et le lactosérum, sur les performances d’engraissement des agneaux de race Rembi. Méthode. Vingt-deux agneaux mâles de la race Rembi, pesant en moyenne 49,08 ± 7,19 kg, ont été répartis en deux groupes : le groupe témoin a reçu une alimentation avec 60 % d’orge, tandis que dans le groupe expérimental, l’orge a été remplacée par des rebuts de dattes broyées. Le concentré expérimental a été humidifié avec du lactosérum à raison de 150 ml.kg-1 avant d’être distribué. L’engraissement a duré 75 jours, avec une période d’adaptation de 15 jours. Résultats. Il en résulte que la ration composée de rebuts de dattes et de lactosérum n’a aucun effet sur le poids vif final des agneaux, cependant elle a influé positivement le gain moyen quotidien (GMQ) avec une différence significative pour le GMQ2 (136,36 g.j-1 pour le lot témoin vs 272,72 g.j-1 pour le lot expérimental). De plus, l’ingéré alimentaire quotidien total a diminué dans le lot expérimental (860 g.j-1 vs 1 450 g.j-1 pour le lot témoin). Conclusions. L’incorporation des rebuts de dattes et de lactosérum dans l’alimentation des agneaux Rembi réduit les coûts de production et préserve l’environnement. Mots-clés. Ovin, indice de consommation d’aliment, résidu, fruits à noyau, sérum de lait, Afrique.

Fixed Point in Non-Archimedeant T-Banach Spaces
In this paper, we introduce the concept of T -normed space in a non-Archimedean space, which is called a non-Archimedean T -normed space and give some properties. After that we prove a common fixed point theorem in a complete non-Archimedean T –normed space for two R-weakly commuting mappings.

Numerical investigation of pulsed flow in aortic aneurism with and without stent by lattice Boltzmann method
Endovascular treatment of aortic aneurysms with an endoprosthesis is proposed for the prevention of the aneurysms' rupture risk and clogging of blood vessels. This paper aims to study the impact of stents with different porosities, placed in fusiform aortic aneurysms, on the hemodynamic parameters: velocity and shear rate of the flow inside the aneurysms, using pulsed boundary conditions derived from real measurements. The numerical investigations are performed with the Lattice Boltzmann method. The blood is treated as a Newtonian fluid and then as a non- Newtonian fluid with the Carreau-Yasuda and Cross models. The reduction obtained by a single stent is modest and unfavorable to thrombotic occlusion. Overlapping of several stents is proposed to promote occlusion. The results found show good agreement with medical theory.

Evaluation of the efficiency and quality of the tram route of Setif city, Algeria: Combining AHP and GIS approaches
The study aims to evaluate the efficiency of the tram track in the urban transport system of the Algerian city of Setif by combining Analytical Hierarchy Process (AHP) and Geographic Information System (GIS) approach. In this research, a set of multiple pre-determined criteria applicable in the field of urban transport were selected for decision-making. They were collected from recent research literature and expert opinions in this discipline, and then were arranged and evaluated in the AHP to extract the main weights for each criterion. In the end, they were processed spatially by using GIS. The study showed that the selection of the tramway track in the city of Setif was not successful in terms of the chosen location, and its selection was not studied according to the efficiency and quality criteria applicable in the field of urban transport. In addition, the study concluded that there is a significant shortfall in the first tram track, especially the one linking the tram route to the northern and southern parts of the city, which affected the efficiency and quality of the tram route. As the results have shown, the percentage of good spaces near the tram route does not exceed 0.34%. It is followed by the percentage of the average and acceptable areas (13.48%) and then the percentage of the marginalized areas and the areas far from the tram track (86.18% of the total area of the city). The study also demonstrated the importance of using AHP and GIS in evaluating a completed tram track according to a comprehensive and widely studied scientific methodology.

Fast xit, [29/01/2026 00:33] : شهدت الجزائر تغيرات على جميع الأصعدة الاقتصادية والاجتماعية والثقافية والتي أثرت على البيئة واستنزفت مواردها وزادت في حدة التلوث، ما أدى إلى ضرورة إدراك ضياع القرار بضرورة الاهتمام والاستجابة الفعلية والفعالة للقضايا البيئية والتدقيق في الكثير من البدائل السياسية العامة والعمل بأحسنها عند صياغة وتنفيذ ما يتم اختياره لتحقيق أهداف التنمية المستدامة، غير أن أغلب السياسات البدئية التنموية في الجزائر لم تصل إلى الأهداف المرجوة على رغم من امتلاكها لمؤشرات بيئية اضمن تحقيق تنمية مستدامة من ثروات طبيعية وبشرية إلا أنها عرضة لاستنزاف الموارد المتجددة والغير متجددة والتي تؤدي إلى عدم الاستدامة كل هذا استدعى حوكمة السياسات البيئية لتحقيق التنمية المستدامة من خلال تفعيل دور الدولة وفق مقترب التسيير العمومي الجديد وإشراك منظمات ومؤسسات القطاع الخاص والمجتمع المدني في عمليات وسياسات البيئة لتحقيق التنمية المستدامة. الكلمات المفتاحية : التنمية المستدامة - السياسة البيئية - حوكمة السياسات البيئية. الملخص بالأجنبية Algeria has witnessed changes in all economic, social and cultural fields that have affected the environment, depleted its resources and increased pollution. This led to the need to recognize the loss of the decision to take care of and respond effectively and effectively to environmental issues and to scrutinize a lot of general political alternatives and work best when Fast xit, [29/01/2026 01:27] المداخلة لقد حدد المشرع الجزائري الشخص المعنوي الذي يكون محل متابعة جزائية، وتم حصره في الأشخاص المعنوية الخاضعة للقانون الخاص والتي تعتبر الشركات التجارية أهمها ، إذ يمكن أن ترتكب هذه الأخيرة جرائم فساد تشكل اعتداء على المصلحة العامة للبلاد، فالبنوك مثلا التي تملك وتسير معظم المال العام هي في الأصل شركات مساهمة، لذلك وجب الحد من الخطورة الإجرامية لها من خلال ضبط أحكام المسؤولية الجزائية للشركات التجارية . من ناحية أخرى نجد أن نطاق جرائم الشركات التجارية توسع، حيث أصبحت نصوص قانون العقوبات غير كافية، فهي لم تستوعب شتى القواعد التي بمقدورها تأمين الحماية اللازمة للمال العام ، وكذا تأمين الحماية لنشاط الشركة من التصرفات غير المشروعة . لذلك تبنى المشرع الجزائري مساءلة الشركات التجارية جزائيا في قوانين خاصة أهمها قانون مكافحة الفساد Summary: The Algerian legislator has identified a person who is a subject of criminal follow-up. and has been confined to the moral persons subject to private law, the most important of which are commercial companies, as the latter may commit corruption offenses that are an attack on the public interest of the country. Therefore, it must be limited by the control of the provisions of criminal liability of commercial companies

Efficient Parallelization of Electromagnetic Field Computations on a Beowulf Cluster
In this paper, efficient high performance computation of electromagnetic field problems using a Beowulf cluster and MatLab® is presented. A cluster with one master node, eight identical computing nodes, and a Gigabit Ethernet (GbE) switch is firstly built. An open source Rocks toolkit solution is used to simplify the process of deploying high-performance parallel computing clusters. Then, three computational electromagnetic applications are developed and implemented on the cluster using parallel MatLab. In the first application, is calculated the input impedance of a multilayer multiconductor circular microstrip antenna that is excited with coaxial probe and operating in a wide frequency band. Parallelization is then performed over the frequency vector permitting a speedup ratio of 23. In the second application, is presented a systematic method for generating and computing symbolic expressions of 3D tetrahedral FEM basis functions of higher orders up to 10. The final application is dedicated to the parallelization of the spatial moment method code for 2D array of bowtie antenna. The simulation results have shown that the array size can be increased considerably leading to a linear system with a size up to 100 times greater than the one under study.

" دور النيابة العامة في حماية الأسرة من التفكك "
إن الأسرة تعد اللبنة الأساس التي يبنى المجتمع الإنساني برمته عليها، والنواة الجوهرية التي يتبلور من حولها، الأمر الذي يجعل تنظيم مقتضياتها وتقنين أحكامها وتقوية مؤسساتها وتعزيز مكوناتها، من الأولويات التي قامت بها سائر المجتمعات. لذلك عنيت بها الشرائع السماوية الثالث، ورسمت قواعد لحكم أحوالها في أدق الجزئيات والتفصيلات، مما نسجت على منواله سائر التشريعات، والتي من بينها التشريع الجزائري، الذي قنَّن فيما ُعِر َف بقانون الأسرة ما يتعلق بها من مقتضيات، والتي ُكللتبما أدخل عليها في " قانون الأسرة " من تعديلات . . ولأهمية الأسرة حرص المشرع الجزائري على إشراك مؤسسة النيابة العامة في الحفاظ على كيان الأسرة من التفكك انطلاقا من مقتضيات المادة 3 مكرر من قانون الأسرة. وبتتبع مجالات تدخل النيابة العامة في القانون، نلاحظ أن تدخلها الرامي إلى حماية الأسرة؛ يتوزع بين ضمان حقوق للزوجة، وأخرى للزوج، وللأطفال، وعديمي الأهلية و المفقودين بنوع من التوازن والعدل والمساواة بدون إفراط ولا تفريط. حيث أنه لكل مكون من مكونات الأسرة دوره الأساسي والمهم الذي يلزم حمايته حماية قانونية وفق مبادئ عامة تفرضها دولة الحق والقانون. ومن أجل تكريس هذه الحماية، عمل المشرع الجزائري على جعل تدخل النيابة العامة في قانون الأسرة متميزا عن تدخلها في باقي فروع القانون المدني، إذ أنها أصبحت تتدخل بصفتها طرفا أصليا حسب ما جاءت به المادة 3 مكرر من قانون الأسرة من أنه: “تعد النيابة العامة طرفا أصليا في جميع القضايا الرامية إلى تطبيق أحكام هذه القانون". هذا القانون إلى جانب قوانين أخرى كقانون الإجراءات المدنية و الإدارية ، وقوانين كفالة الأطفال المهملين ،و الذي خولت بدورها للنيابة العامة صلاحيات مختلفة وواسعة تهدف من خلالها أساسا إلى حفظ حسن سير الإدارة وحماية المراكز القانونية للأشخاص دون التفريط في حماية المجتمع فضال عن حماية الأطراف الضعيفة الجديرة بالعناية.
