This paper presents a dynamic behaviour study of non-linear friction systems subject to uncertain friction laws. The main aspects are the analysis of the stability and the associated non-linear amplitude around the steady-state equilibrium. As friction systems are highly sensitive to the dispersion of friction laws, it is necessary to take into account the(More)
OBJECTIVE Decreased expression of diacylglycerol kinase delta (DGKδ) has been linked to insulin resistance in humans and mice and it is abundantly expressed in adipose tissue. Therefore, its role in adipogenesis was examined. DESIGN AND METHODS 3T3-L1 pre-adipocytes were generated in which DGKδ expression had been knocked down and the effect of this on(More)
Human activities often generate or increase concentration of chemical compounds including pesticides, hydrocarbons and metals that can potentially affect ecological interactions. We found that elevated levels of zinc in pigeon feathers were associated with both low prevalence of Chlamydiaceae (ornithosis disease) and low intensity of blood pathogens(More)
Flexible polyurethane (PU) foam is widely used in numerous comfort applications such as automotive seat cushions and mattresses. It would be interesting to design a mechanical model which describes the behaviour of this material in a series of test conditions. The present study is devoted to the modelling of the quasi-static behaviour of polyurethane foam(More)
