In this paper, the initial part of a laboratory and numerical experimental campaign dedicated to historical masonry is described. One leaf panels with regular texture are built in order simulate material characterised by strong resisting elements weak mortar joints. Laboratory tests first components then behaviour compression panels, which applied both orthogonal parallel bed joints, highlight ...

A wave propagation laboratory is proposed which enables the study of the interaction of broadband signals with complex materials. A physical experiment is dynamically linked to a numerical simulation in real time through transmitting and recording transducer surfaces surrounding the target. The numerical simulation represents an arbitrarily larger domain, allowing experiments to be performed in...

An alternative learning approach for destructive testing of structural specimens in civil engineering is explored by using a remote laboratory experimentation method. The remote laboratory approach focuses on overcoming the constraints in the hands-on experimentation without compromising the understanding of the students on the concepts and mechanics of reinforced concrete structures. The goal ...

Informal experimentation in economics goes back at least as far as Bernoulli (1738) (in connection with the Petersburg game), and formal reports of laboratory experiments as such have appeared for some time now (see e.g. Allais, 1953; Chamberlin, 1948; Flood, 1958; Friedman, 1963; May, 1954; Sauermann and Selten, 1959; Siegel and Fouraker, i960; Smith, 1962; Stone, 1958). There are even survey ...

The practice of animal research is at once familiar and strange. On the one hand, almost everyone knows that it is a regular and widespread part of modern scientific and medical research. Indeed, the idea of being a “lab rat” or “guinea pig” is frequently invoked and readily understood in contemporary discourse. On the other hand, the vast majority of animal research is conducted outside public...

There exists currently a fair degree of introspection in the pain research community about the value of animal research. This review represents a defense of animal research in pain. We discuss the inherent advantage of animal models over human research as well as the crucial complementary roles animal studies play vis-à-vis human imaging and genetic studies. Finally, we discuss recent developme...

Once again, the forthcoming IUPS Congress in Helsinki provides an opportunity for physiologists to strengthen old ties and build new collaborations with associates in other countries. Such collaborations are an essential element in the continued vitality of science in laboratories throughout the world. In October 1986, I urged APS members to “Lend a Helping Hand” to scientists in developing cou...

The scientific literature of laboratory animal research is replete with papers reporting poor reproducibility of results as well as failure to translate results to clinical trials in humans. This may stem in part from poor experimental design and conduct of animal experiments. Despite widespread recognition of these problems and implementation of guidelines to attenuate them, a review of the li...

Radiotelemetry is the "state of the art" for monitoring physiological functions in awake and freely moving laboratory animals, while minimizing stress artifacts. For researchers, especially those in the fields of pharmacology and toxicology, the technique provides a valuable tool for defining the physiological and pathophysiological consequences derived from advances molecular, cellular, and ti...
