Fluid-structure interaction in a free end textile vascular prosthesis
Textile cardiovascular prostheses are tubular structures made of polyester
filaments. They present particular mechanical properties linked to wavy form
of their walls allowing them to stretch under pressure. Pulsatile blood flow
was studied in a moving walls vascular prosthesis. First, an image
processing device was used to measure prosthesis displacement under air
pressure in an free end impregnated textile prosthesis. Then,
fluid-structure interaction is simulated with a numerical computation code
allowing to couple prosthesis walls motion with blood flow.
Navier-Stokes equations governing fluid flow are numerically solved with
N3S code based on finite elements method. The numerical process is based on
the Arbitrary Lagrangian Eulerian (ALE) formulation allowing moving domains.
The obtained results showed a particular distribution of blood flow
velocities and shear stress near the graft walls. The flow velocity
distribution near a prosthetic surface is strongly influenced by the
crimping morphology and deformation. A local flow analysis is imperative to
understanding pathologies implying hemodynamic factors and to optimize the
prosthesis design
Agricultural Economics and Policy Reforms. Module 5: Policy Reform and Natural Resource Management
(NATURA European Community Training Programme for Agricultural Universities in Southern Regions (NECTAR) ; Edition CIHEAM)
Morocco
Morocco has well developed irrigation facilities that range from small scale communal systems based on springs, qanats or river diversions to groundwater-based individual initiatives and large scale public schemes. Water demand policies – e.g. water pricing, shift to drip irrigation, 'aquifer contracts' and other forms of participatory management – have shown little potential in curbing overexploitation of resources in many basins. Expansion of irrigated areas and the priority given to productivity have taken their toll on the environment, favored commercial agriculture, and contributed to a net depletion of groundwater estimated at 1 billion m3/year. There is a need to better align agricultural development, water conservation, and environmental objectives. After a short historical perspective, this chapter first reviews a number of trends in the irrigation sector (modernization, development of groundwater resources, wastewater reuse and desalination), before turning to regulatory and institutional issues, including participatory management, economic tools, privatization and an examination of the Plan Maroc Vert. The threats posed by climate change, water scarcity, and environmental degradation are then discussed

Imagining the state through social protest: state reformation and the mobilizations of unemployed graduates in Morocco
This article discusses the transformation of the Moroccan state under contemporary neoliberal globalization, and considers what this transition means for the ways in which scholars view state-society interplay in Morocco and the Arab world more generally. Specifically, it examines the protest of unemployed graduates in Morocco, suggesting that public demonstrations are not only a means to communicate and mobilize demands, but also a technology to reclaim and reproduce a particular “truth” in public. This truth does not necessarily equate with the reality of the neoliberal state as a dispersed material force. As such, by looking at the case of Morocco, we hope to instigate further debate on the nature of the state and its specific relation to phenomena as globalization, society and social protest
