This article highlights the need to rethink how to manage mobility in Morocco more intelligently, given that it is a major pillar of economic competitiveness. Smart mobility based on Intelligent Transport Systems (ITS) allows to improve and ensure the optimal use of existing infrastructure before embarking on heavy and irreversible infrastructure projects. The case regarding the separation of the urban traffic and the Heavy Goods Vehicles (HGV) traffic circulating between Casablanca Port and Zenata Dry Port is a relevant example where smart mobility could provide efficient solutions without building costly tunnels. A dynamic simulation was made using the Aimsun software to quantify the relevance of the proposed lane designated to HGV in the existing road. This simulation allows to visualise congestion sections and quantify the circulation of vehicles and pedestrians. The article presents defined functions and characteristics of the Advanced Traffic Management (ATM) to ensure the optimal operation and efficient setting of the simulation. All appliances, hardware, and sensors that will be set up on-site will help to improve traffic safety, traffic flow, traffic information, and reduce congestion and pollution. This case study illustrates the complexity of managing the flow of goods in cities and suggests how to solve this type of problems using smart mobility. This research proposes reserving a special lane for HGV. ITS will help this cost-optimal alternative, will promote the urban framework of the coastal road, and contribute to sustainable mobility in Casablanca.

Thymolipoma is a rare benign neoplasm of the thymus containing both mature adipose tissue and thymic tissue. We report a case of a 34‐year‐οld man, presenting a mass of the anterior mediastinum, the radiology investigation and operatory piece diagnosed a thymolipoma.This study highlights the clinical diagnostic and therapeutic features as well as the evolutionary characteristics of this entity.

La néphrolithotomie percutanée s´accompagne d´un risque de complications en particulier hémorragiques, qui en fait une technique potentiellement invasive. Nous rapportons le cas d´une patiente de 70 ans, traité auparavant pour néphrolithotomie percutanée d´une lithiase sur un rein unique gauche. Une hématurie persistante de moyenne abondance est apparue il y a 2 mois et demi, et qui a motivé à la réalisation d´une tomodensitométrie découvrant un faux anévrisme intra rénal polaire inférieur, d´origine iatrogène. Il a nécessité une embolisation sélective efficace à la colle biologique.

Le mésentère commun complet est une anomalie rare de rotation du tube digestif. Sa découverte est exceptionnelle à âgé adulte; à cette période, il demeure très souvent asymptomatique et donc non diagnostiquée. Le mésentère commun complet peut être découvert de façon fortuite, lors d'un syndrome appendiculaire ectopique, comme ce fut le cas de notre observation. Il s'agissait d'un patient âgé de 42 ans, qui à présenté un tableau inflammatoire clinico-biologique aiguë pelvien. La TDM a permis de poser le diagnostic d'une appendicite aigue sur un mésentère commun complet. Le traitement par laparotomie a confirmé le diagnostic d'une appendicite aiguë perforée sur la malrotation intestinale. Les suites post appendicectomies étaient favorables.

The walls of buildings experience heat, air and moisture transfers. These transfers have a significant influence on indoor climate, since they affect the value of temperature and relative humidity inhouses. High levels of humidity lead to pathologies in the buildings, and influence the air quality and the hygrothermal comfort of the occupants. In this work, a numerical analysis of the behaviour of polystyrene mortar under hydric solicitations was led. The simulations were held using ComsolMultiphysics and MATLAB. There were two different moisture transfer models used in this work: the first one took into account sorption hysteresis phenomenon, and the other one did not. The computed results showed that considering sorption hysteresis in modelling the hydric behaviour of the material allows obtaining more accurate results comparing to a model that does not consider hysteresis.

In order to keep up with the requirements of sustainable development, there is a growing interest towards reducing the energy consumption in the construction and rehabilitation of buildings and the promotion of recycling waste in building materials. The use of recycled polystyrene beads in cement-based materials composition constitutes a solution to improve the insulation in buildings. This allows also limiting landfill by reusing the polystyrene waste. The aim of this study is to compare some properties and performances of a cement paste containing polystyrene beads to a reference paste designed with only the same cement. An experimental campaign was conducted and the obtained results showed that adding recycled polystyrene beads to a cement paste improves its hygro-thermal properties. Further studies are however necessary to better understand the real role of the polystyrene beads in the heat and mass transfers.

Abstract Introduction Subacute combined degeneration of the spinal cord is a rare cause of demyelination of the dorsal and lateral columns of the spinal cord and is a neurological complication of vitamin B12 deficiency. Subacute combined degeneration without anemia or macrocytosis is rare. Case presentation We present a case of cobalamin deficiency in a 29-year-old Moroccan woman who presented with subacute combined degeneration without evidence of anemia or macrocytosis. Magnetic resonance imaging of the spinal cord demonstrated abnormal hyperintense signal changes on T2-weighted imaging of the posterior and lateral columns from the medulla oblongata to the thoracic spine. A diagnosis of subacute combined degeneration of the spinal cord was considered and confirmed by low serum cobalamin. The patient was treated with vitamin B12 supplements and showed improvement in her clinical symptoms. Conclusion Physicians should diagnose subacute combined degeneration in patients early by having a high index of suspicion and using diagnostic tools such as magnetic resonance imaging.
