A similarity law for stressing rapidly heated thin-walled cylinders

When a thin cylindrical shell of uniform thickness is very rapidly heated by hot high-pressure gas flowing inside the shell, the temperature of material decreases steeply from a high temperature at the inside surface to ambient temperatures at the outside surface. Young's modulus of material thus varies. The purpose of the present paper is to reduce the problem of stress analysis of such a cylinder to an equivalent problem in conventional cylindrical shell without temperature gradient in the wall. The equivalence concept is expressed as a series of relations between the quantities for the hot cylinder and the quantities for the cold cylinder. These relations give the similarity law whereby strains for the hot cylinder can be simply deduced from measured strains on the cold cylinder and thus greatly simplify the problem of experimental stress analysis

Current influences on traditional Chinese medicine education in the UK: the experience of a collaborative programme between Middlesex University and Beijing University of chinese medicine.

A long and successful collaboration has existed between Middlesex University and Beijing University of Chinese Medicine in the delivery of high quality education and practitioner training in Traditional Chinese Medicine (TCM) in the UK. A joint degree programme was validated by the two Universities in 1997 offering integrated training at undergraduate level in both Chinese Herbal Medicine and Acupuncture & Moxibustion. This programme was the first of its kind to be offered in Europe by a public sector higher education institute. Students on the programme undertake academic study at Middlesex University and gain clinical experience on placement in hospitals affiliated to Beijing University of Chinese Medicine in addition to practitioner training in the UK at the Asante Academy of Chinese Medicine. There have been several drivers for the relatively recent move towards degree status for TCM, along with other Complementary and Alternative Medicine (CAM) professions in the UK. Concern over patient safety and the rising popularity of CAM led to an inquiry being held by a House of Lords select committee. Their report, published in 2000, made several recommendations, including that the acupuncture and herbal medicine professions seek statutory status. Following this recommendation, the UK Department of Health launched a public consultation in March 2004, seeking views on proposals for statutory professional self-regulation of these professions. In developing its proposals, the Department of Health considered and built on the recommendations of two independent regulatory working groups for Acupuncture and Herbal Medicine. The views expressed in the consultation will help frame the provisions to be included in an order to be laid before the UK Parliament prior to becoming law. The matters which concern a regulatory body include education, registration, continuing professional development and disciplinary and ethical matters. A pre-requisite for regulation is the establishment of a core curriculum and minimum standards for competent practice as well as an expert mechanism to assess educational qualifications. This paper considers the impact of the move towards statutory self-regulation on the development of TCM education in the UK and the implications of future regulatory frameworks for educational institutions

A computer solution for the dynamic load, lubricant film thickness, and surface temperatures in spiral-bevel gears

A computer method for determining the dynamic load between spiral bevel pinion and gear teeth contact along the path of contact is described. The dynamic load analysis governs both the surface temperature and film thickness. Computer methods for determining the surface temperature, and film thickness are presented along with results obtained for a pair of typical spiral bevel gears

Multiple-Scale Analysis of the Quantum Anharmonic Oscillator

Conventional weak-coupling perturbation theory suffers from problems that arise from resonant coupling of successive orders in the perturbation series. Multiple-scale perturbation theory avoids such problems by implicitly performing an infinite reordering and resummation of the conventional perturbation series. Multiple-scale analysis provides a good description of the classical anharmonic oscillator. Here, it is extended to study the Heisenberg operator equations of motion for the quantum anharmonic oscillator. The analysis yields a system of nonlinear operator differential equations, which is solved exactly. The solution provides an operator mass renormalization of the theory.Comment: 12 pages, Revtex, no figures, available through anonymous ftp from ftp://euclid.tp.ph.ic.ac.uk/papers/ or on WWW at http://euclid.tp.ph.ic.ac.uk/Papers/papers_95-6_.htm
