The paper covers some material and computational aspects of the rock mechanics of leached cavities in salt. A material model is presented in which the instantaneous stiffness of the salt is obtained by interpolation between the unloaded state and a relevant failure state. The model enables prediction of short term triaxial behaviour from uniaxial stress-strain curves. Key results from a nonlinear
This article intends to shed some light on the contextual realities that shape the perceptions and practices of corporate social responsibility (CSR) in Saudi Arabia. Using both primary and secondary data collection and analysis, we chart some of the key socio-cultural and business drivers that shape the picture of Saudi Arabian CSR. In addition to providing an account of an important, but signifi
Have small states become more influential in a complex multi-actor governance system, and are there special ways of exerting influence for small states in the EU? According to some scholars small states can become more influential in an international system where sovereignty is under challenge and large multilateral institutions – the EU being the most obvious example – are assuming greater import
I argue that Lisa Shapiro’s rational reconstruction of Descartes’s provisional moral code in terms of a broad conception of morality supplies us with an interpretative framework that make historiographical sense of the reception of Descartes’s moral philosophy in an Anglophone context on three occasions: the appeal to Descartes made by Henry More, Henry Sidgwick’s abrupt dismissal, and the ensuing
This paper presents a generic system dynamic model to simulate and analyze a desertification system and its stability for different desertification syndromes. The study is one of many desertification related modelling approaches carried out by different project partners within the frames of DeSurvey (A Surveillance System for Assessing, Monitoring and Modelling Desertification; 2005-2010). DeSur
Methane is a powerful greenhouse gas and growing concern regarding global climate changes and landfill gas is regarded as one of the major sources for methane migration to the atmosphere. In this study we present research work with the objective to evaluate the use of 3D geoelectrical resistivity to detect gas migration in landfills. Extensive field experiments were conducted at the Filborna landf
Extensive changes in public organizations have been carried through since the end of the 20th century as a way of achieving higher efficiency. Inspiration came from the private sector. The Swedish Enforcement Authority carried through several organizational changes during this time. The authority was during 1997-2006 organized in ten independent authorities subordinated to the National Tax Board.
The time dependent Maxwell system is supplemented with the constitutive relations of linear bianisotropc media and is treated as a neutral integro-differential equation in a Hilbert space. By using the theory of abstract Volterra equations and strongly continuous semigroups we obtain general well-posedness results for the corresponding mathematical problem.
