Tisser… du textile au discours : paroles féminines d’un patrimoine immatériel
Creators: name: Chikhaoui, Naima
Publisher: name: Bulletin d’Archéologie Marocaine
Year: 2020

description: La pratique du tissage se conjugue au féminin dans différentes aires géographiques et couvre des ères des plus reculées. Cette portée spatiotemporelle étendue en fait un document à teneur culturelle matérielle et immatérielle quant à sa dimension anthropologique et archéologique. Il est question de traces et de signes relatifs à un univers féminin, inscrites dans un textile qui stimule la réflexion sur une part de la vision des sociétés, leurs organisations sociales et leurs dynamiques de genre. Des repères à parcourir pour pénétrer l’étoffe tissée et tenter d’analyser ses contenus dans leurs moindres nœuds exécutés dans une sacralité du geste, et qui est portée par tout un imaginaire. Une parole qui en se tissant dans une matérialité en laine, narre la vie et inscrit des sens. La vocation de cette contribution est de traiter du tissage selon un regard d’anthropologie de genre.

La transmission des traditions céramiques au Maroc : pour une vision globale
Creators: name: Elbourkadi, Ikhlass
Publisher: name: Bulletin d’Archéologie Marocaine
Year: 2020

description: Nous avons mis l’accent dans cet article sur le phénomène de transmission des traditions céramiques au Maroc, en se référant à plusieurs communautés de pratique. Dans le monde rural, celles du Rif exclusivement féminines, et celles de Tamegrout au sud et Beni Sidal au Nord véhiculées par les hommes ; dans le milieu urbain, à Salé et à Safi. Ces communautés ont été observées dans leurs contextes quotidiens plus ou moins structurés. Nous avons examiné sur le terrain et selon une vision globale, les trois modalités de transmission considérées actives au Maroc, à savoir : l’enculturation, l’imprégnation et la socialisation professionnelle. Alors, c’est un engagement scientifique qui redynamise la recherche sur la poterie marocaine, en soulevant la question suivante : comment un novice, en côtoyant l’expert, arrive-t-il à maîtriser l’identité technique de son groupe ? Et en tentant d’expliquer les dynamiques socio-économiques en rapport avec les processus d’apprentissage et de la mémorisation des fonds techniques hérités.

Subjects: subject: 620 Engineering & allied operations

description: The rising interest in developing gas turbines make it important to investigate them in energy generation from solid biomass. Addiotionally, externally fired gas turbine plant has the advantage of solid fuel flexibility. Pressure and air mass flow through the clean cycle side are optimized to provide the maximum power. Hardware-in-the-loop (HiL) is integrated beside the real combustion process. It serves in being more flexible in tuning plant parameters for several values, for instance, heat exchanger design, compressor and turbine efficiencies, and pressure and mass flow values.

description: Les fouilles archéologiques de la mosquée d’Agadīr Amghār à Aḳḳa (province de Tata)5 avaient pour objectif de lever le voile sur un site énigmatique du sud-est marocain, qui a été longtemps consi­déré comme almohade, du fait des simples similitudes existant entre l’allure de son minaret et ceux des célèbres mosquées de Marrakech et Rabat. Les investigations menées sur le terrain durant deux campagnes de fouilles, ont prouvé que cet édifice religieux date de l’époque sa‘adienne au moment où la Zaouïa d’Aḳḳa jouissait d’une grande aura sous l’impulsion de son fondateur Sīdī Muḥammad ibn Mbārk, et jouait un rôle décisif dans l’incubation du mouvement politique et religieux naissant dans le Sud au début du 16e siècle. L’agglomération hérita aussi du rôle précurseur de sa voisine en déclin, la célèbre métropole commerciale et minière de Tamdūlt.

description: Le site archéologique de Ksar Seghir consiste en un établissement d’époque médiévale qui se situe sur la rive sud du Détroit de Gibraltar. Il a connu son apogée sous les mérinides en tant que ville et en tant que port. En 1458, elle fut conquise par les Portugais qui y demeurèrent jusqu’à 1550, puis après son évacuation l’agglomération tomba en ruines. Le site a connu une grande campagne de fouille archéologique réalisée par une mission maroco-américaine entre 1974 et 1981, avec l’excavation de 18 % de l’ensemble et le dégagement d’un nombre considérable de structures islamiques et portugaises. À partir de 2011, une équipe maroco-portugaise y réalise des travaux archéologiques. Dans cette contribution, nous allons examiner deux espaces domestiques conservés dans les niveaux islamique et portugais, tout en essayant d’élaborer une synthèse sur l’évolution de l’architecture domestique à Ksar Seghir entre le 14e et le 16e siècles.

description: Sub-Saharan Africa is facing food security challenges due, in part, to decades of soil nitrogen (N) depletion. Applying N fertilizer could increase crop yields and replenish soil N pools. From 2010 to 2015, field experiments conducted in Embu and Kiboko, Kenya and Harare, Zimbabwe investigated yield and N uptake response of six maize (Zea mays L.) hybrids to four N fertilizer rates (0 to 160 kg N ha−1) in continuous maize production systems. The N recovery efficiency (NRE), cumulative N balance, and soil N content in the upper 0.9 m of soil following the final harvest were determined at each N rate. Plant and soil responses to N fertilizer applications did not differ amongst hybrids. Across locations and N rates, NRE ranged from 0.4 to 1.8 kg kg−1. Higher NRE values in Kiboko and Harare occurred at lower post-harvest soil inorganic N levels. The excessively high NRE value of 1.8 kg kg−1 at 40 kg N ha−1 in Harare suggested that maize hybrids deplete soil inorganic N most at low N rates. Still, negative cumulative N balances indicated that inorganic soil N depletion occurred at all N rates in Embu and Harare (up to − 193 and − 167 kg N ha−1, respectively) and at the 40 kg N ha−1 rate in Kiboko (− 72 kg N ha−1). Overall, maize N uptake exceeded fertilizer N applied and so, while yields increased, soil N pools were not replenished, especially at low total soil N levels (< 10,000 kg N ha−1 in top 0.9 m).

description: Très tôt les gravures rupestres de l’Est marocain ont attiré l’attention tant par la diversité des su­jets et des thèmes identifiés que par les figures représentées et la qualité des images. Des gravures d’élé­phants comme celles de Hassi Ghilan, qui nous intéressent ici tout particulièrement, sont signalées également dans d’autres stations de l’Est marocain. Les représentations de ces pachydermes associés à des figures anthropomorphes font partie d’un ensemble remarquable de gravures à prédominance animalière si riche qu’il mérite d’être étudié en détails. Ces éléphants nous renseignent sur le milieu naturel d’avant l’aridité dans cette zone géographique du Maroc oriental et nous rappellent la richesse de la faune rupestre et de l’ancien paysage de la zone des Hauts Plateaux, patrimoine naturel encore méconnu de milieux dont il reste beaucoup à explorer.

Creators: name: Vuong, Thanh Huyen
Publisher: name: Universität Rostock
Year: 2017
Subjects: subject: 540 Chemistry & allied sciences

description: The aim of this thesis is to develop novel modified VOx/Ce1-xMxO2 catalysts (M = Zr, Ti, Mn) that are capable of converting NOx and NH3 to N2 well below 300 °C at a high GHSV. Various methods of preparation of the supports, as well as the influence of the co-components (Zr4+, Ti4+, Mnn+), were investigated and evaluated to study the structural properties and catalytic activity. Furthermore, analysis of the catalysts under reaction conditions using in situ techniques, such as EPR, UV-Vis-DRS, and DRIFTS-spectroscopy, allowed the identification of structure-reactivity relationships.

description: The automotive sector increasingly demands safety technologies such as flame-retarded materials used for electric vehicles. Suitable materials are needed for the fire protection of a Rechargeable Energy Storage System (REESS) - including battery, housing and control electronics - against an external source of damage such as a fuel fire outside the car, and also against internal technical failure of the REESS such as an internal fire and (in the worst case) thermal-runaway of the entire REESS. To meet the requirements, the flame retardancy of the REESS housing materials is of great importance. Here, we report the flame retardancy behavior of thermoplastic and thermoset composites in the event of an external fire, studied by a bench-scale fuel fire test which simulates the fire treatment of the UNECE-R100-8E on component level.

description: Abstract

The rate at which signals can be transmitted between single neurons limits the speed of information processing. Cerebellar mossy fibre boutons are able to maintain synchronous neurotransmitter release at very high action potential frequencies, up to ∼1 kHz. The neurotransmitter release occurs at the presynaptic active zone and is controlled by highly localised calcium signals. In order to allow reliable, fast synaptic transmission, calcium ions must be cleared from the active zone. However, the exact mechanisms of calcium clearance remain elusive. Despite the recent advances in imaging technology, it is not yet possible to measure localised calcium signals on the nanometre scale. Nevertheless, it is possible to address the impact of localised calcium signals on neurotransmitter release with use of computational modelling. In this study, I established an experimentally constrained model of an active zone of the cerebellar mossy fibre bouton. My simulations revealed that endogenous fixed buffers that have low calcium binding capacity (∼15) and low affinity for binding calcium in combination with mobile buffers with high affinity for binding calcium enable rapid clearance of calcium from the active zone during high-frequency firing. Moreover, during high-frequency firing, slow endogenous mobile buffers prevent build-up of the intracellular calcium concentration. The results presented in this work suggest that reduced calcium buffering speeds active zone calcium signalling, thus allowing high rates of synaptic transmission.

Integrated Control of Solidification Microstructure and Melt Pool Dimensions In Additive Manufacturing Of Ti - 6Al - 4V
Creators: name: Gockel, Joy E.
Publisher: name: Figshare
Year: 2018
Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: Additive manufacturing (AM) offers reduced material waste and energy usage, as well as an increase in precision. Direct metal AM is used not only for prototyping, but to produce final production parts in the aerospace, medical, automotive and other industries. Process mapping is an approach that represents process outcomes in terms of process input variables. Solidification
microstructure process maps are developed for single bead and thin wall deposits of Ti-6Al-4V via an electron beam wire feed and electron beam
powder bed AM process. Process variable combinations yielding constant beta grain size and morphology are identified. Comparison with the process maps for melt pool geometry shows that by maintaining a constant melt pool cross sectional area, a constant grain size will also be achieved. Additionally, the grain morphology boundaries are similar to curves of constant melt pool aspect ratio. Experimental results are presented to support the numerical predictions and identify a proportional size scaling between beta grain widths and melt pool widths. Results demonstrate that in situ, indirect control of solidification microstructure is possible through direct melt pool dimension control. The ability
to control solidification microstructure can greatly accelerate AM process qualification potentially allow for tailored microstructure to the desired application.

description: Le goût de la parure ou le besoin d’être paré fut développé depuis les époques préhistoriques, où l’Homme a saisi le rôle fédérateur de la parure, celle-ci a été produite sur plusieurs supports (coquillages, dents des animaux, pierres…). L’utilisation de la parure a donné naissance à un débat important concernant l’émergence de la complexité cognitive et la pensée abstraite chez les atériens, population caractéristique du MSA en Afrique du Nord. Ce travail s’intéresse uniquement au côté technique et fonctionnel des objets de parure en coquillages marins de la grotte d’El Khenzira I dans la région d’El Jadida, il tente d’apporter quelques éléments de réponses sur les différentes méthodes et techniques de perforations effectuées par les até­riens et les ibéromaurusiens, ainsi que les fonctions et les utilités de ces objets pour ces deux entités culturelles. Pour atteindre cet objectif, nous nous sommes appuyés sur une approche expérimentale et fonctionnelle, qui vont nous permettre de reconstituer la mémoire des gestes et la chaîne opératoire de la perforation d’une part et les fonctions de ces « perles » en d’autre part. Le protocole expérimen­tal a été exécuté sur une collection de coquilles marines de trois espèces à savoir : (Littorina obtusata, Trivia arctica et Pecten maximus ) qui proviennent de la région de Témara-Skhirat, plusieurs techniques de perforation ont été entreprises afin d’établir une comparaison entre les objets expérimentaux et archéologiques, et de vérifier s’il y a une filiation technologique entre les até­riens et les ibéromaurusiens de la grotte d’El Khenzira I. L’approche expérimentale a permis de fournir des résultats très satisfaisants. Elle a montré les caractéristiques et les détails technologiques de chaque type de perforation.

Investigation and Mitigation of Degradation in Hydrogen Fuel Cells

subject: FOS: Mechanical engineering

description: The ever increasing demand of petroleum in the transport sector has led to depletion of low cost/low risk reserves, increased levels of pollution, and greenhouse gas emissions that take a heavy toll on the environment as well as the national economy. There is an urgent need to use alternative energy resources along with an efficient and affordable energy conversion system to arrest environmental degradation. Polymer electrolyte fuel cells (PEFCs) show great promise in this regard - they use hydrogen gas as a fuel that electrochemically reacts with air to produce electrical energy and water as the by product. In a fuel cell electric vehicle (FCEV), these zero tail pipe emission systems offer high efficiency and power density for medium-heavy duty and long range transportation. However, PEFC technology is currently challenged by its limited durability when subjected to harsh and adverse operating conditions and transients that arises during the normal course of vehicle operation. The hydrogen-based fuel cell power train for electric vehicles must achieve high durability while maintaining high power efficiency and fuel economy in order to equal the range and lifetime of an internal-combustion-engine vehicle. The technology also needs to meet the cost targets to make FCEVs a commercial success. In this dissertation, one of the degradation phenomena that severely impede the durability of the system has been investigated. In scenarios where the cell becomes locally starved of hydrogen fuel, “cell reversal” occurs, which causes the cell to consume itself through carbon corrosion and eventually fail. Carbon corrosion in the anode disrupts the original structure of the electrode and can cause undesirable outcomes like catalyst particle migration, aggregation, loss of structural and chemical integrity. A comprehensive study using advanced electrochemical diagnostics and high resolution 3D imaging was performed and a new understanding to extend PEFC life time and robustness, by implementing engineered materials solutions, has been achieved. This will eventually help in making fuel cell systems more efficient, durable and economically viable, in order to better harness clean energy resources.

description: There is a growing demand for miniature, high-precision components and devices with micro-scale features for applications in biomedical systems, aerospace structures, and energy storage/conversion systems. Mechanical micromachining has become a leading approach to address this demand. In micromachining, a micro-scale cutting tool, such as a micro-endmill with a diameter as small as 10 um, is rotated by an ultra-high-speed (UHS) spindle (speeds greater than 60,000 rpm, reaching up to 500,000 rpm) to mechanically remove the material from a workpiece. Although micromachining resembles the traditional computer numerically controlled (CNC) machining processes, the micron-scale cutting tools, ultra-high-speed (UHS) spindles, and considerably tighter tolerance requirements bring unique challenges to micromachining.

description: Designing user-interfaces so that first-time or infrequent users can accomplish their goals by exploration has been an enduring challenge in Human-Computer Interaction. Iterative user-testing is an effective but costly method to develop user-interfaces that support use through exploration. A complementary method is to use modeling tools that can generate predictions of user exploration given a user-interface and a goal description. Recent computational models of goal-directed user exploration have focused on predicting user exploration of websites and demonstrated how predictions can inform user-interface design. These models employ the common concepts of label following and information scent: that the user's choice is partly determined by the semantic relevance between the user's goal and the options presented in the user-interface. However, in addition to information scent, other factors including the layout position and grouping of options in the user-interface also affect user exploration and the likelihood of success. This dissertation contributes a new model of goal-directed user exploration, called CogTool- Explorer, which considers the layout position and the grouping of options in the user-interface in concert with a serial evaluation visual search process and information scent. Tests show that predictions from CogTool-Explorer match participant data better than alternative models that do not consider layout position and grouping. This dissertation work has also integrated the CogTool- Explorer model into an existing modeling tool, called CogTool, making it easier for other researchers and practitioners to setup and generate predictions of likely user exploration paths and task performance using CogTool-Explorer.

description: Divers indices qui pourraient attester de la présence d’une capacité cognitive chez les groupes humains atériens et de l’acquisition probable d’un langage articulé ont été mis en évidence dans de nombreux sites du Middle Stone Age (MSA) en Afrique. Les fouilles archéologiques effectuées jusqu’à présent dans de nombreux sites MSA marocains comme les grottes des Pigeons à Taforalt, de Bizmoune, El Mnasra et Rhafas entre autres sites ont livré une quantité remarquable de matières colorantes. Ce sont des éléments minéraux (oxydes de fer et hydroxides de fer) sous plusieurs formes et couleurs (noir, orange, rouge et jaune) qui témoignent d’un savoir-faire technique, probablement aussi de pensée abstraite, d’une gestion économique et de pratiques « esthétiques » entre autres fonc­tions. Sur la base des résultats issus d’une étude expérimentale et de leur comparaison avec les données archéologiques, nous présentons dans cet article une reconstitution des procédés de fabrication et de traitement des matières colorantes, et des fonctions probables par les populations atériennes des grottes de Bizmoune et du Rhafas.

description: We experimentally demonstrate enhanced self-phase modulation (SPM) in silicon nitride (Si3N4) waveguides integrated with 2D graphene oxide (GO) films. GO films are integrated onto Si3N4 waveguides using a solution-based, transfer-free coating method that enables precise control of the film thickness. Detailed SPM measurements are carried out using both picosecond and femtosecond optical pulses. Owing to the high Kerr nonlinearity of GO, the hybrid waveguides show significantly improved spectral broadening compared to the uncoated waveguide, achieving a broadening factor of up to ~3.4 for a device with 2 layers of GO. By fitting the experimental results with theory, we obtain an improvement in the waveguide nonlinear parameter by a factor of up to 18.4 and a Kerr coefficient (n2) of GO that is about 5 orders of magnitude higher than Si3N4. Finally, we provide a theoretical analysis for the influence of GO film length, coating position, and its saturable absorption on the SPM performance. These results verify the effectiveness of on-chip integrating 2D GO films to enhance the nonlinear optical performance of Si3N4 devices.

description: Dans beaucoup de pays les projecteurs se sont de plus en plus braqués sur le rôle essentiel de l’entrepreneuriat dans la reprise de l’activité économique. Le Maroc comme plusieurs autres gouvernements, a souvent accordé une grande importance de ses programmes de relance à l’aide attribuée aux entrepreneurs, qu’elle prenne la forme, de crédits alloués à la recherche pour stimuler l’innovation, de garanties d’emprunts, d’allègements fiscaux ou encore d’encouragement à la création d’entreprise. Toutefois, c’est plutôt aux investissements favorisant l’environnement qu’on donne la priorité. Par exemple les projets visant à l’amélioration et l’efficacité énergétique, au développement des modes de transport durables, à la protection des espaces verts, à l’encouragement au recours aux énergies renouve1ab1es, à l’agriculture durab1e, à 1a gestion durab1e de l’eau, à 1a valorisation des déchets et à 1’éco-construction.La transition donc, vers une économie verte respectueuse de l’environnement et favorisant 1a création de richesses et d’emplois durab1es, s’inscrit comme un objectif majeur de 1a politique de développement territorial durab1e des pays en général et du Maroc en particulier. En effet, La prise de conscience croissante des enjeux environnementaux permet ainsi de favoriser 1a transition vers une économie verte. Ainsi, l’entrepreneuriat vert constitue aujourd’hui une nouvelle dynamique économique en p1eine évo1ution. Dans ce cadre, nous allons essayer à travers cette communication de comprendre les concepts clés de l’entrepreneuriat vert et du développement territorial durable, ainsi que le rôle joué par l’Etat dans la promotion de l’entrepreneuriat vert. Pour atteindre cet objectif, nous allons structurer ce travail autour de deux axes. Dans le premier, nous allons décortiquer les concepts de l’entrepreneuriat vert et le développement territorial durable. Quant au second, analyserons les différents diapositifs et politiques de promotion de l’entrepreneuriat vert mises en place par le gouvernement marocain.

description: Self-supervised models for speech processing form representational spaces without using any external labels. Increasingly, they appear to be a feasible way of at least partially eliminating costly manual annotations, a problem of particular concern for low-resource languages. But what kind of representational spaces do these models construct? Human perception specializes to the sounds of listeners' native languages. Does the same thing happen in self-supervised models? We examine the representational spaces of three kinds of state-of-the-art self-supervised models: wav2vec 2.0, HuBERT and contrastive predictive coding (CPC), and compare them with the perceptual spaces of French-speaking and English-speaking human listeners, both globally and taking account of the behavioural differences between the two language groups. We show that the CPC model shows a small native language effect, but that wav2vec 2.0 and HuBERT seem to develop a universal speech perception space which is not language specific. A comparison against the predictions of supervised phone recognisers suggests that all three self-supervised models capture relatively fine-grained perceptual phenomena, while supervised models are better at capturing coarser, phone-level, effects of listeners' native language, on perception.

description: Entrepreneurship through the platform strategy has gained increasing research attention in recent years. To date, research has not adequately explained how entrepreneurs discover opportunities related to the development of digital business platforms (DBPs), which creates a gap in the entrepreneurship literature. Through in-depth case studies of three digital business platforms, I show that entrepreneurs discover opportunities related to the information that they already possess, the interaction with the market and with their social network. I use these findings to draw several implications, including: (1) entrepreneur’s prior knowledge about how to serve markets influences their discovery of how to use DBPs to serve a market; (2) entrepreneurial alertness is an important antecedent of DBPs development; (3) Weak ties are more important than strong ties in developing a strong network effect that leads to a Successful DBP. Overall, we conclude that, unlike offline entrepreneurship, opportunities are not obvious for anyone, that is to say, entrepreneurs need a combination of prior knowledge, entrepreneurial alertness and social network to recognize and develop a DBP that meets the target customers needs.

Subjects: Survival, pharmacy, entrepreneurial profile, environment

description: This article aims to understand and analyze the determinants of the survival of pharmacies in Morocco. Referring to previous academic researchs, we hypothesize that survival is explained by three factors: the pharmacist's profile, the organizational characteristics of the business and the business environment. We examine this hypothesis on a sample of 120 Moroccan pharmacies. The results obtained show that the human and social capital available to a pharmacist contributes to improving the probability of survival of his business (gender, entrepreneurial environment, motivation). The environment in which the pharmacy is created also contributes to the survival of the Moroccan pharmacy through entrepreneurial training and support for the pharmacist. As for organizational characteristics, it should be noted that there is a positive correlation between the size of the start-up capital and survival. Unfortunately, state support in this area is ineffective (investment subsidies, state coverage of part of salaries), except for exemptions from social security charges.

description: Implementation of reliable rating systems for small credit portfolio is hindered by non-observed default events in databases and short time series of data available. In this study we propose an approach to handle those two challenges while developing rating systems. We further extend the approach by estimating systematic risk, that is, co-movements of creditworthiness of debt securities' issuers over time. Based on financial information from the PSVaG's debt securities portfolio, we could show that including a systematic risk component significantly increase the model accuracy.
