Phase 1 of the near term hybrid passenger vehicle development program. Appendix B: Trade-off studies, volume 1
Tradeoff study activities and the analysis process used are described with emphasis on (1) review of the alternatives; (2) vehicle architecture; and (3) evaluation of the propulsion system alternatives; interim results are presented for the basic hybrid vehicle characterization; vehicle scheme development; propulsion system power and transmission ratios; vehicle weight; energy consumption and emissions; performance; production costs; reliability, availability and maintainability; life cycle costs, and operational quality. The final vehicle conceptual design is examined
Measuring Propagation Speed of Coulomb Fields
The problem of gravity propagation has been subject of discussion for quite a
long time: Newton, Laplace and, in relatively more modern times, Eddington
pointed out that, if gravity propagated with finite velocity, planets motion
around the sun would become unstable due to a torque originating from time lag
of the gravitational interactions.
Such an odd behavior can be found also in electromagnetism, when one computes
the propagation of the electric fields generated by a set of uniformly moving
charges. As a matter of fact the Li\'enard-Weichert retarded potential leads to
a formula indistinguishable from the one obtained assuming that the electric
field propagates with infinite velocity. Feyman explanation for this apparent
paradox was based on the fact that uniform motions last indefinitely.
To verify such an explanation, we performed an experiment to measure the
time/space evolution of the electric field generated by an uniformely moving
electron beam. The results we obtain on such a finite lifetime kinematical
state seem compatible with an electric field rigidly carried by the beam
itself.Comment: 23 pages, 15 figure
In the Wake of Catalona: An Alternative Model to Safeguard Research Participants’ Interests in their Biological Materials
On February 23, 2006, four men were indicted in connection with a 1,000 per body from which they mined tissues, organs, and bones without the consent of the deceased’s families. They then sold the parts for research, medical education, and transplantation. Once harvested for valuable parts, the corpses were either cremated or stuffed with “PVC plumbing pipe in place of the bones” and sewed back up for a funeral.\u
Eco-friendly gas mixtures for Resistive Plate Chambers based on Tetrafluoropropene and Helium
Due to the recent restrictions deriving from the application of the Kyoto
protocol, the main components of the gas mixtures presently used in the
Resistive Plate Chambers systems of the LHC experiments will be most probably
phased out of production in the coming years. Identifying possible replacements
with the adequate characteristics requires an intense R&D, which was recently
started, also in collaborations across the various experiments. Possible
candidates have been proposed and are thoroughly investigated. Some tests on
one of the most promising candidate - HFO-1234ze, an allotropic form of
tetrafluoropropane- have already been reported. Here an innovative approach,
based on the use of Helium, to solve the problems related to the too elevate
operating voltage of HFO-1234ze based gas mixtures, is discussed and the
relative first results are shown.Comment: 9 pages, 6 figures, 1 tabl
Esquema de información de clima para turismo aplicado al balneario Pehuen Co, Argentina
El objetivo del trabajo es efectuar los primeros estudios sobre el bioclima del balneario de Pehuen Co, al suroeste de la provincia de Buenos Aires (Argentina). Se utiliza el Esquema de Información de Clima para Turismo (CTIS en inglés) para identificar los meses con mayor potencial turístico. Se modifica el CTIS para adaptarlo a las características climáticas del balneario. Este esquema puede ser aplicado por los agentes turísticos o turistas para identificar de forma rápida y sencilla los mejores meses según la actividad que deseen realizar
Reviving the Modern Rule in the Interpretation of Tax Statutes: Baby Steps Taken in Canada Trustco, Mathew, Placer Dome and Imperial Oil
Canada Trustco, Mathew, Placer Dome and Imperial Oil are landmark decisions of the Supreme Court of Canada in terms of their illumination on the principle of statutory interpretation. In these cases, the Court stated that the Income Tax Act should be interpreted in accordance with a textual, contextual and purposive approach. This amounts to a revival of the modern rule of statutory interpretation and a move away from the plain meaning approach previously adopted by the Court. This article argues that the steps taken by the Court in reviving the modern rule are merely baby steps, as many key questions remain inadequately addressed. The article first discusses the rise and fall of the modern rule in Canadian tax jurisprudence. It then analyzes each of the four decisions and highlights the contribution of each case to the development of the textual, contextual and purposive interpretation. The article concludes with some thoughts on the challenges facing the courts in establishing the purpose of provisions of the Act and offers some suggestions for moving forward
