Monitoring trucks to reveal Belgian geographical structures and dynamics: From GPS traces to spatial interactions
International audience Despite the fact that freight transport has a huge impact on the economy and the environment, datasets have always been scarce or restricted to very small a-spatial samples. We here aim at diverting spatial data collected in Belgium for tolling trucks proportionally of their u...
Equity in transportation: guidelines for stakeholders and practitioners
Simultaneous Interaction with In-Vehicle Systems while Turning Left: Comparison among three groups of drivers
The growing introduction of new technologies inside vehicles represents a set of extra information sources. Its use can interfere with the driving activity and induce performance decrements. An on-road experiment was conducted to investigate how drivers reacted to the simultaneous interaction with i...
Keeping pace with the seasons
This article explores the role of seasons in the nomadic and pastoral practices of two Turkish-speaking pastoralist populations who live in large areas of Inner Asia with marked continental climates: the Yakuts in alaas of the Eastern Siberia taiga forest region, and the Kazakhs in the steppes of Ce...
Leaf-cutting ants, biology and control
International audience Leaf-cutting ants (Formicidae, Myrmicinae, Attini) are found on the American continent and in the Caribbean and are known to live in symbiosis with a fungus. Among Attini tribe, Atta and Acromyrmex are the two genera, which commonly depend on fresh plant leaves and other plant...

Shoreface morphodynamics in Ireland and France
International audience The shoreface is defined as the transition zone between the beach and the inner shelf. Its morphodynamics are driven by weather-wave climate interaction where, during fair weather, shoaling waves favour onshore sediment transport, whereas high-energy events produce offshore di...
The establishment of medical activity centers at the public hospital: what is the impact of a change in organizational structure on the decision-making process?
Managing Work-Integrated Learning : the Influence of Co-Operative Education on Organizational Commitment and Turnover
Within the organizations, the turnover when limited can have a positive influence on the resources’ renewal. But when it grows, it badly affects the organization leading to a management of the immediate, jeopardizing people and company’s effectiveness. Veolia Group is suffering from this regular org...
A reduced-complexity shoreline change model combining longshore and cross-shore processes: The LX-Shore model
International audience A reduced-complexity numerical model, LX-Shore, is developed to simulate shoreline evolution along wave-dominated sandy coasts. The model can handle any sandy shoreline geometries (e.g. sand spits, islands), including non-erodible areas such as coastal defenses and headlands,...

Roles of oestradiol receptor alpha and beta against hypertension and brain mitochondrial dysfunction under intermittent hypoxia in female rats
International audience AimChronic intermittent hypoxia (CIH) induces systemic (hypertension) and central alterations (mitochondrial dysfunction underlying cognitive deficits). We hypothesized that agonists of oestradiol receptors (ER) α and β prevent CIH‐induced hypertension and brain mitochondrial...
A Survey on Cross-Layer Design Frameworks for Multimedia Applications over Wireless Networks
In the last few years, the Internet throughput, usage and reliability have increased almost exponentially. The introduction of broadband wireless mobile ad hoc networks (MANETs) and cellular networks together with increased computational power have opened the door for a new breed of applications to...

Influence of the aerosol solar extinction on photochemistry during the 2010 Russian wildfires episode
In this work, impact of aerosol solar extinction on the photochemistry over eastern Europe during the 2010 wildfires episode is discussed for the period from 5 to 12 August 2010, which coincides to the peak of fire activity. The methodology is based on an online coupling between the chemistry-transp...
Shared access, cognitive radio and transition issues
International audience During the last decade, consumers have largely benefited from technological advances in the telecom sector: broadband has increased, access to the network became mobile/ubiquitous, the prices of services and terminals have become much more affordable, the usage of technology i...
Building a Model to Reconstruct the Hellenistic and Roman Road Networks of the Eastern Desert of Egypt, a Semi-Empirical Approach Based on Modern Travelers’ Itineraries
International audience The Egyptian Eastern Desert, the part of the Sahara Desert that connects the Nile and the Red Sea, is rich in natural resources and meshed with multiple networks. The adoption of the camel as the main mode of transportation in the 1st millennium BC, faster and with a greater l...
Modelling energy demand and CO2 emissions associated with changes in household consumption patterns. A macro-micro long-term analysis based on time use.
Household energy consumption represents a significant share of final energy use, especially when both direct and embodied energy are taken into account. Several academic studies, as well as the recommendations of the United Nations and of non-governmental organisations, suggest that a shift in consu...
Can digital technologies induce behavioral changes in transportation habits? Evidence based on User Experience with the SmartMoov Application
This study aims to assess behavioral changes in transportation habits induced by real-time and multimodal information provided by a mobile application, SmartMoov. The users of SmartMoov (beta-testers) were selected on a voluntary basis. After three months of testing the mobile application in a livin...
Arctic Corridors and Northern Voices: Governing marine transportation in the Canadian Arctic (Coral Harbour, Nunavut community report).
Ship traffic in the Canadian Arctic nearly tripled between 1990 and 2015. The Government of Canada is developing a network of low-impact marine transportation corridors in the Arctic that encourages marine transportation traffic to use routes that pose less risk and minimize the impact on communitie...
Intracellular transport of AMPA receptors and regulation via their associated proteins
Learning and memory rely on synaptic plasticity events during which the neuron modulates the efficiency of synaptic transmission. These events require a strict spatial and temporal control of the number of alpha-amino-3-hydroxy-5-méthyl-4-isoxazolepropionate receptors (AMPAR) at the post-synaptic pl...
The mutation of Pro789 to Leu reduces the activity of the fast-twitch skeletal muscle sarco(endo)plasmic reticulum Ca2+ ATPase (SERCA1) and is associated with Brody disease
Brody disease is a rare inherited disorder of fast-twitch skeletal muscle function and is characterized by a lifelong history of exercise-induced impairment of skeletal muscle relaxation, stiffness, and cramps. The autosomal recessive inheritance of mutations in ATP2A1, the gene encoding SERCA1, whi...
Governing rail freight in France and Germany (1990-2010) : diffusion processes of reforming policy statements
Transporting more goods by train is a leitmotif of transport policies since the 1990s, at the age of sustainable development. This thesis analyzes the formulations and recomposition of policy statements on rail freight in France and Germany between 1990 and 2010, through the study of four cases. Sus...
Island and local grocer. Food products supply in the Ponant Islands
The Ponant Islands are diverse in terms of population, surface or distance from the continent. Most of food products consumed on these islands are coming from the continent. It is therefore necessary to transport them to the island, all along a route whose main element is the sea crossing. This is w...
Stability of the Mediterranean's thermohaline circulation under modified surface evaporative fluxes
A series of experiments with an ocean general circulation model of the Mediterranean forced by artificial (but realistic) surface fluxes of heat and fresh water is performed over 100 year periods. The model has a stable thermohaline circulation under the baseline fluxes. Small increases/decreases in...
