Single-phase mixed aluminates-titanates Nd1-x Sr x Al1-x Ti x O3 (x = 0.3 ÷ 0.9) were prepared from stoichiometric amounts of constituent oxides Nd2O3, Al2O3, TiO2 and strontium carbonate SrCO3 by solid-state reaction technique in air at 1773 K. Crystal structure parameters of Nd1-x Sr x Al1-x Ti x O3 were refined by full-profile Rietveld refinement in space groups R [Formula: see text] c (x = ...

Accurate measurements of the electrical resistivity, the thermoelectric power and the thermal conductivity of TbZn are reported at the ferromagnetic-structural transition. The temperature derivative of the coefficients is examined. The critical behaviours are understood in terms of conduction electron scattering on spin correlated fluctuations and the presence of structural and magnetic domains...

We developed a computational model based on a finite-element mixed formulation with quadratic isoparametric beam elements. We applied this model to the analysis of a blade-wagon: a novel structure characteristic of an innovative concept in wind-power called VGOT Darrieus turbine. We studied the structural behaviour of its main components: chassis, suspension and blade, using combinations of bea...

Heterogeneity in Risky Choice Behaviour in a Broad Population We analyse risk preferences using an experiment with real incentives in a representative sample of 1,422 Dutch respondents. Our econometric model incorporates four structural parameters that vary with observed and unobserved characteristics: Utility curvature, loss aversion, preferences towards the timing of uncertainty resolution, a...

in order to determine the relationship between knowledge, attitude and health behaviour among menopausud women, a random sample of 250 menopaused women was studied. the data was collected by using a questionnaire and analysed by the spss programe. the study showed that seventy woman (28%) had good knowledge, only twenty seven women (11%) had a positive attitude, and forty women (16%) had good h...

This paper presents a methodology for reducing the uncertainty related to the structural behaviour of an existing building in view of a vulnerability assessment regarding future earthquake actions. Estimating the lateral load resistance is a step towards evaluating the capacity of a structure to resist earthquake actions. The prediction of structural behaviour by numerical models is inevitably ...

BACKGROUND Compliance with surgical checklist use remains an obstacle in the context of checklist implementation programs. The theory of planned behaviour was applied to analyse attitudes, perceived behaviour control, and norms as psychological antecedents of individuals' intentions to use the checklist. METHODS A cross-sectional survey study with staff (N = 866) of 10 Swiss hospitals was con...

This paper extends the Function-Behaviour-Structure (FBS) framework, which proposed eight fundamental processes involved in designing. This framework did not explicitly account for the dynamic character of the context in which designing takes place, described by the notion of situatedness. This paper describes this concept as a recursive interrelationship between different environments, which, ...

This paper proposes a comprehensive schema to represent an agent’s social knowledge using the Function – Behaviour – Structure (FBS) schema. Although this schema has originally been developed to represent knowledge about design objects, it is sufficiently abstract to also describe knowledge about agents. This paper shows how such an FBS view can be useful to support the interaction of situated ...
