Heptageniid mayfly nymphs have been suggested as sensitive indicators of metal contamination in streams based on biomonitoring studies, experimentation in situ, and experimentation in microcosm. Laboratory tests were conducted to evaluate the sensitivity of Rhithrogena hageni, a heptageniid mayfly, to waterborne copper, cadmium, and zinc. Tests were conducted with soft water (hardness = 40-50 m...

Pasteurella haemolytica is a major contributor to neonatal pneumonia in lambs; which continues to be a major problem. Experimentation was conducted to determine the efficacy of vaccinating pregnant ewes to reduce the incidence of pneumonia in newborn lambs. Vaccines utilized in this experimentation included three different commercial Pasteurella haemolytica vaccines intended for use in cattle a...

In the European Union (EU), animal welfare is seen as a matter of great importance. However, with respect to animal experimentation, European citizens feel quite uninformed. The European Directive 2010/63/EU for the protection of laboratory animals aims for greater transparency and requires that a comprehensible, nontechnical summary (NTS) of each authorised research project involving animals i...

Those with genuinely humane motives are most likely to prolong life or alleviate suffering by bringing existing medical knowledge to bear in those parts of the world where men and women are suffering and dying because they cannot afford any treatment Yet many scientists prefer Animal rights activists are often accused of showing to spend their lives in laboratories causing untold more concern f...

As part of its mission to promote efficient, cost-effective, ethical research with animals, and to those ends to identify valuable laboratory animal resources, the Institute of Laboratory Animal Resources (ILAR) of the National Research Council's Commission on Life Sciences was charged with addressing a new and rapidly developing application of molecular biology to animal experimentation termed...

Tunable Diode Laser Absorption Tomography (TDLAT) is a non-intrusive measurement technique for determining two-dimensional spatially resolved distributions of temperature and species concentration in high enthalpy flows. TDLAT combines infrared laser absorption spectroscopy with tomographic image reconstruction. Having previously been implemented at the University of Virginia's Aerospace Resear...

This paper presents a laboratory for remote automatic control via Internet. This distributed laboratory (DLAB) is located at POLITEHNICA University of Bucharest (PUB). The control architectures are based on advanced communication technologies, distributed measurement systems, and virtual instrumentation. Software agents are assisting the users in performing their activity. The results obtained ...

The original publication is available at www.springerlink.com Abstract. Identifying the characteristics of biological systems through physical experimentation, is restricted by the resources available, which are limited in comparison to the size of the parameter spaces being investigated. New tools are required to assist scientists in the effective characterisation of such behaviours. By combin...

This study was conducted to ascertain the attitudes of first year medical students to human and animal experimentation, while undergoing a course in Muscle and Nerve experimental Physiology. At the time of administration of the questionnaire, students had been exposed to both human as well as animal experiments. Approximately 81% of the students preferred human experiments (P < 0.05). This pref...
