Mixing formulas in time domain

This paper discusses the dispersive properties of dielectric materials both in the time and the frequency domains. Special emphasis is on the treatment of heterogeneous materials, in particular two-phase mixtures. A time domain Maxwell Garnett rule is derived which differs from the corresponding frequency domain formula in the respect that it is expressed in terms of convolutions and inverse opera

Heat transfer through protective clothing under symmetric and asymmetric long wave thermal radiation

Abstract in French Cette etude reprend les resultats d'une recherche co-financee par la Communaute Europeenne sur les effets thermiques des vetements de protection et sur l'astreinte physiologique qui en resulte dans les conditions de travail. L'etude concerne l'infiuence de l'asymetrie de rayonnement thermique. L'echange thermique a ete mesure al'aide d'un mannequin calorimetrique sous l'influencThis report considers results of an ED funded research on thermal properties ofprotective clothing and their use in the assessment of the thermal strain at work. In order to study the effects of the asymmetry oflong wave thermal radiation on the heat transfer through protective clothing, the heat loss under all-side and unilaterally applied radiation with the same incident radiant power of 279 W/m

Implementational space for multilingualism at a Swedish university following the passing of the Swedish Language Act

In order to meet the demands of globalization, universities across the world are in the process of managing issues of multilingualism (Doiz et al. 2013; van der Walt 2013). In Sweden, since the passing of the Language Act in 2009, state-funded universities are obliged to use Swedish as their official language while also becoming increasingly internationalized. While the Language Act makes Swedish
