Evolution tectonique et magmatique du NW du massif de Tazekka (Maroc oriental). Tectonic and magmatic evolution of the NW Tazekka massif (Eastern Morocco).

International audienceL'examen des événements tectoniques, métamorphiques et magmatiques de la partie NW du massif de Tazekka (Maroc oriental) a permis de mettre en évidence une évolution tectonique et magmatique polyphasée, définie par : (1) la mise en place des dolérites dans les plans de stratification S0 par mécanisme de sills alimentés à partir de dykes ; (2) une phase majeure de structuration caractérisée par de rares plis synschisteux de direction N10 à N30 et à plan axial subhorizontal marqué par la schistosité S1 ; (3) une phase de plissement qui reprend les structures précédentes, marquée par des plis de direction N00 à N60 synschisteux, dont le plan axial est généralement redressé avec un pendage modéré à fort vers l'est ; (4) la mise en place des granites, à l'origine d'un important métamorphisme de contact polyphasé, marqué principalement par la recristallisation de la cordiérite, suivi par une nouvelle phase de plissement pénécontemporaine de la deuxième manifestation métamorphique (biotites orientées dans la schistosité S3). Les plis P3, de direction N05 à N80, associés à la phase de plissement P3, présentent une schistosité S3 de plan axial à pendage généralement fort à modéré vers l'ouest ; (5) des chevauchements affectant l'ensemble des structures précédemment formées ; (6) des cassures tardi-hercyniennes. The study of the tectonic, metamorphic and magmatic events of the NW Tazekka massif (Eastern Morocco) has permitted to evidence a polyphased tectonic and magmatic evolution characterized by : (1) the installation of dolerites in the bedding planes by injection of sills fed by dykes; (2) a major phase of deformation characterized by rare synschistous folds, from the direction N10 to N30 and an axial sub-horizontal plane marked by S1 schistosity; (3) a phase of folding that refolded the former structures, characterised by N00 to N60 direction synschistous folds, whom axial plane is generally rectified with a strong to moderate dip towards east; (4) the emplacement of granites, at the origin of an important polyphased contact metamorphism, particularly marked by the recrystallization of cordierite, followed by a new penecontemporaneous folding phase of the second metamorphic manifestation (oriented biotites in S3 schistosity). The P3 folds, from the direction N05 to N80, associated with the P3 folding phase, show an axial plane schistosity S3 with a generally strong to moderate dip towards the west; (5) thurst faults affecting all the former structures; (6) late-hercynian fractures

The Development of Soft Skills via In-person Training in Secondary Education: A Case Study in Oujda-Angad Directorate, Morocco

The digital revolution has brought about colossal changes in many social aspects. Thanks to the emergence of new digital technologies, many jobs have been executed by machines. Thus, employers are seeking different skills; they are known as soft skills. These skills are currently required for integrating the workforce. This article provides conceptual and empirical information related to employability skills development. It aims to explore the effect of soft skills training on the development of this skill among secondary school students. It is preliminary research to check students’ knowledge of three skills: Critical thinking, Collaboration and Communication. The theoretical frameworks mobilized for this study are the project-based learning theory and the experiential learning theory (Kolb, 2005). A mixed approach is adopted to examine the development of these skills via a one-month in-person training for students of Oued Eddahab high school. Quantitative data were collected via two web-based questionnaires: a pre-training and a post-training to compare students’ perceptions regarding the soft skills training. Qualitative data were collected by recording two focus groups. The quantitative results have revealed that there are many effective strategies to apply in order to enhance soft skills in high school. The qualitative results revealed that there is a positive relationship between the training workshops and the improvement of those skills. The majority of the students have expressed their satisfaction with the different workshops and stressed the importance of these skills for their academic and professional careers and for the improvement of their communicative capacities

Structure property investigation of glass-carbon prepreg waste-polymer hybrid composites degradation in water condition

The limited shelf life of carbon prepreg waste (CPW) from component manufacturing restricts its use as a composite reinforcement fibre on its own. However, CPW can be recycled with glass fibre (GF) reinforcement to develop a unique remediate material. Therefore, this study fabricated (1) a glass fibre-carbon prepreg waste reinforced polymer hybrid composite (GF-CPW-PP), (2) a polypropylene composite (PP), (3) a carbon prepreg waste reinforced composite (CPW-PP), and (4) a glass fibre reinforced composite (GF-PP) and reported their degradation and residual tension properties after immersion in water. The polymer hybrid composites were fabricated via extrusion technique with minimum reinforce glass-carbon prepreg waste content of 10 wt%. The immersion test was conducted at room temperature using distilled water. Moisture content and diffusion coefficient (DC) were determined based on water adsorption values recorded at 24-h intervals over a one-week period. The results indicated that GF-PP reinforced composites retained the most moisture post-168 h of immersion. However, hardness and tensile strength were found to decrease with increased water adsorption. Tensile strength was found to be compromised since pores produced during hydrolysis reduced interfacial bonding between glass fibre and prepreg carbon reinforcements and the PP matrix
