ESP Needs Analysis of Agricultural Engineering Students

The present study attempts to examine the English language needs of the engineering students majored in agricultural studies in IAV – Complexe Horticole d’Agadir (CHA) in Morocco. The study was conducted in the third semester in the academic year 2018-2019. The use of a mixed-method research design allowed us to collect data from various stakeholders including 39 students, 30 alumni, 13 specialty-subject teachers and the ESP teacher. Three data collection instruments were used, namely questionnaires, interviews and a placement test. The SPSS software was used to code and analyse the quantitative data of the questionnaires, whereas the qualitative data collected from the interview was described, interpreted and summarized. The findings of the study emphasized the importance of English for agricultural engineering students. Besides, the study determined the students’ English language needs and depicted their learning preferences with regard to the ESP course. In the end, a number of implications and recommendations are drawn for the stakeholders

Fracturación asociada a pliegues en las calizas jurásicas de las cadenas del Sur del Rif (Marruecos)

The study of fractures affecting the Jurassic Ridges of Fert El Bir, Kefs and Outita from South Rifian Ridges, Northern Morocco, allowed us to propose a folding-fracturing model that summarizes the distribution of fractures within fault-propagation folds and the chronology of the different families of fractures occurring during the history of Miocene and Quaternary shortening phases, oriented NE-SW. At the beginning of compressional phase, sedimentary series corresponding mainly to limestones are deformed by layer parallel shortening (LPS) accompanied by pure shear causing thickening with the occurrence of oblique and transverse fractures. Following the establishment of the ramp fold, existing fractures are locally affected by simple shear within the two flanks of the fold and axial fractures are developed as a response of the accommodation of the surface foldingA partir del estudio de la fracturación en los materiales jurásicos de las estribaciones del sur de las cadenas rifeñas (norte de Marruecos), se propone un modelo de plegamiento y fracturación que explica la distribución de fracturas en pliegues de propagación de fallas, así como la cronología de las distintas familias de fracturas formadas durante la historia deformacional del Mioceno y Cuaternario (compresión NE-SW). Al comienzo de la etapa compresiva, las secuencias sedimentarias sufrieron una deformación por acortamiento paralelo a las capas (layer-parallel shortening, LPS), acompañada de cizalla pura que trajo como resultado el engrosamiento de las capas y la aparición de fracturas oblicuas y transversas. Después del emplazamiento del pliegue asociado a la falla, las fracturas sufrieron desplazamientos en los dos flancos del pliegue, y se formaron nuevas fracturas como resultado de la acomodación a la superficie de plegamient

Análisis de lineamientos en las rocas que afloran en el sinclinal de Ouaouizaght, Alto Atlas Central

In this work, we perform a lineament analysis of the Ouaouizaght syncline area (Central High Atlas, Morocco) in terms of their structural and tectonic significance. The methodology consists of satellite image (Lansat 8 OLI) processing by means of principal component analysis (PCA). The maximum of lineament orientation in the study area shows a NE-SW direction and two relative maxima oriented N0 and N90. The higher density areas of lineaments are located along the four borders of the Ouaouizaght syncline probably highlighting the importance of major faults characterized by diapiric processes ( e.g., movement of salt towards the anticline cores delimiting the Ouaouizaght syncline) during the extensional stageand importance of these previous discontinuities in the subsequent tectonic inversionEn este trabajo realizamos un análisis de lineamientos en el área del sinclinal de Ouaouizaght (Atlas Alto Central, Marruecos) para entender su significado estructural y tectónico. La metodología consiste en el procesamiento de la imagen de satélite Lansat 8 OLI por medio de un análisis de componentes principales. La orientación principal de los lineamientos obtenidos que se deduce en el área de estudio es NE-SO y además se observan dos máximos relativos orientados N0 y N90. Las áreas que presentan una mayor densidad de lineamientos se localizan a lo largo de los cuatros márgenes del sinclinal de Ouaouizaght. Esto probablemente refleja la importancia de las fallas principales caracterizadas por procesos diapíricos ( e.g. , movimiento de sal hacia los núcleos de los anticlinales que bordean el sinclinal de Ouaouizaght) durante la etapa extensional y la importancia de estas discontinuidades previas en la posterior inversión tectónic

Topografía y evolución de los sistema de drenaje en «cuenca de Volubilis» (Cadenas sud-rifeñas, Marruecos)

The Volubilis piggy -back basin, located at the front of the Rif belt, northern Morocco, is a subsided area, as a continuation of the deformational orogenic ridges, related to the present-day African and Eurasian convergence. For the first time, by morphotectonic studies, we analyzed the topographic evolution and drainage systems response. Our results proved the influence of active tectonics in the drainage network and topography of the Volubilis basin. The young phase is indicated by a less dissected planation surface comparing to the ridges, as well as by the ε-shaped hypsometric curve of the khoumane river. This latter drains the continuation of the basin and the eastern arc, where the tectonic activity is mostly concentrated. Based on swath analysis, the general trend of tilting was characterized and was attributed to the recent tectonic movement combined with folds growth of the ridgesLa cuenca de piggy-back de Volubilis, situada en el frente del Rif es una área deprimida localizada en el frente del cinturón orogénico, formado a su vez en relación con con la convergencia entre Africa y Eurasia. Este estudio morfotectónico novedoso analiza por primera vez la topografía y la respuesta de los sistemas de drenaje a la tectónica. Nuestros resultados demuestran una influencia de la tectónica reciente en la topografía. Los indicios de la fase más reciente están en relación con una superficie de erosión menos disecada en relación con las zonas elevadas, así como con la curva en del perfil del río Khoumane. Este último drena la continuación de la cuenca y arco oriental, donde se concentra la mayor parte de la actividad tectónica. A partir del análisis de perfiles swath se ha caracterizado el patrón general de basculamiento, relacionado con los movimientos tectónicos recientes y levantamiento de cadena

Mapping Agricultural Soil in Greenhouse Using an Autonomous Low-Cost Robot and Precise Monitoring

Our work is focused on developing an autonomous robot to monitor greenhouses and large fields. This system is designed to operate autonomously to extract useful information from the plants based on precise GPS localization. The proposed robot is based on an RGB camera for plant detection and a multispectral camera for extracting the different special bands for processing, and an embedded architecture integrating a Nvidia Jetson Nano, which allows us to perform the required processing. Our system uses a multi-sensor fusion to manage two parts of the algorithm. Therefore, the proposed algorithm was partitioned on the CPU-GPU embedded architecture. This allows us to process each image in 1.94 s in a sequential implementation on the embedded architecture. The approach followed in our implementation is based on a Hardware/Software Co-Design study to propose an optimal implementation. The experiments were conducted on a tomato farm, and the system showed that we can process different images in real time. The parallel implementation allows to process each image in 36 ms allowing us to satisfy the real-time constraints based on 5 images/s. On a laptop, we have a total processing time of 604 ms for the sequential implementation and 9 ms for the parallel processing. In this context, we obtained an acceleration factor of 66 for the laptop and 54 for the embedded architecture. The energy consumption evaluation showed that the prototyped system consumes a power between 4 W and 8 W. For this raison, in our case, we opted a low-cost embedded architecture based on Nvidia Jetson Nano

LA CONTRIBUTION DES ÉLÉMENTS DE L’ENVIRONNEMENT PHYSIQUE A LA SATISFACTION EXPONENTIELLE DANS LES SERVICES : CAS DES HÔTELS CLUBS D’AGADIR

Depuis les années 80 et suite à l’article pionnier d’Holbrook et Hirchman, de nombreux chercheurs et praticiens se détournent des pratiques marketing traditionnelles au profit du marketing expérientiel.  Ainsi les entreprises de service en général et les hôtels en particulier préfèrent opter pour un positionnement expérientiel, en permettant au visiteur de vivre une expérience gratifiante et mémorable. Dans ce cas l'environnement de l’hôtel joue un rôle primordial en permettant au client d'éprouver certaines réactions affectives.Cette recherche tente de relever les facteurs de l’environnement physique pouvant expliquer le niveau de satisfaction des consommateurs des hôtels clubs de la ville d’Agadir et de mettre en évidence leur impact respectif sur la satisfaction globale et la fidélit

Mapping the pollution plume using the self-potential geophysical method: case of Oum Azza Landfill, Rabat, Morocco

The main landfill in the city of Rabat (Morocco) is based on sandy material containing the shallow Mio-Pliocene aquifer. The presence of a pollution plume is likely, but its extent is not known. Measurements of spontaneous potential (SP) from the soil surface were cross-referenced with direct measurements of the water table and leachates (pH, redox potential, electrical conductivity) according to the available accesses, as well as with an analysis of the landscape and the water table flows. With a few precautions during data acquisition on this resistive terrain, the results made it possible to separate the electrokinetic (~30%) and electrochemical (~70%) components responsible for the range of potentials observed (70 mV). The plume is detected in the hydrogeological downstream of the discharge, but is captured by the natural drainage network and does not extend further under the hills.info:eu-repo/semantics/publishedVersio

New Ethylenediamine Crosslinked 2D-Cellulose Adsorbent for Nanoencapsulation Removal of Pb (II) and Cu (II) Heavy Metal Ions: Synthesis, Characterization Application, and RSM-Modeling

The main objective of the present work is to elaborate on a new eco-friendly and efficient adsorbent designated for aquatic micropollutants removal. However, the synthesis of the Ethylenediamine Crosslinked 2D-Cellulose green adsorbent was carried out successfully, by partial grafting of benzyl entities onto hydroxyl groups of HEC, and crosslinking with ethylenediamine ED. Further, the new ethylenediamine crosslinked 2D-Cellulose was used as a biosorbent for nanoencapsulation removal of copper and lead heavy metal ions from aqueous solutions. The proposal chemical structures of unmodified and modified materials were confirmed using FTIR, XRD, TGA, and SEM–EDX analysis. Furthermore, many parameters of the optimization for Pb (II) and Cu (II) in terms of removal efficiency including pH, adsorbent amount, and contact time were optimized by response surface methodology with a Box–Behnken design. Based on the desirability optimization with three factors, the maximal removal was 99.52% and 97.5% for Pb(II) and Cu(II), respectively and was obtained at pH = 5.94, 22.2 mg as the optimal adsorbent amount, and 21.53 min as contact time
