Journal- Based Reflection in Undergraduate Service Learning and the University Therapeutic Riding Center
Principles of Therapeutic Riding, Animal Science 3309, is a service- based learning course that gives undergraduates the opportunity to participate in hippotherapy sessions. This course first offered in 1998, has been held for 12 semesters. A total of 233 students from over 15 majors have been trained in this discipline. Advanced Therapeutic Riding, Animal Science 4001, is a continuation of the Principles class that allows students to participate in the sessions and serve in leadership roles. This class has been active for 8 semesters and has included 51 students
Water Fluoridation: The Engineers' Contribution
The benefits of fluoridation were formally endorsed in North America in 1951 and for nearly sixty years a diverse range of communities have been adjusting the fluoride content in water supplies to reduce dental decay. Australian fluoridation commenced in 1953 in Tasmania and expanded to the other states because of the enthusiastic efforts of engineers in partnership with the dental profession. The purpose of this paper is to highlight the early contribution of engineers in fluoridation research and to acknowledge the role of four Australian engineers, Mr F Grey (Tasmania), Mr H J N Hodgson (South Australia), Mr M A Simmonds (Queensland) and Dr M J Flynn (New South Wales). The history of fluoridation and the multidisciplinary approach to its implementation has relevance today as reuse of water and beneficial use of biosolids is subjected to community debate
Multiple hadron production in e+e- annihilation induced by heavy primary quarks. New analysis
In this paper we present an analysis of the multiple hadron production
induced by primary heavy quarks in e+e- annihilation with the account of most
complete and corrected experimental data. In the framework of perturbative QCD,
new theoretical bounds on the asymptotically constant differences of the
multiplicities in processes with light and heavy quarks are given.Comment: 26 pages, 7 figures, to be published in Particles & Nucle
Questions and Remarks About Clans in Multiparticle Dynamics
The fact that several important effects in multiparticle dynamics, on which
QCD has not yet satisfactory predictions, have been interpreted in terms of the
validity of negative binomial (Pascal) regularity and related clan properties
at the level of simpler substructures, raises intriguing questions on clan
properties in all classes of collisions, the main one being whether clans are
observable objects or merely a mathematical concept. We approach this problem
by studying clan masses and rapidity distributions in each substructure for
e+e- annihilation and hh collisions, and find that such properties can indeed
characterise the different components. These results support the idea that
clans could be observable, a challenging problem for future experiments.Comment: 11 pages; 3 figures; latex 2e and amsmat
The lepton flavor violating decays in the simplest little Higgs model
In the simplest little Higgs model the new flavor-changing interactions
between heavy neutrinos and the Standard Model leptons can generate
contributions to some lepton flavor violating decays of -boson at one-loop
level, such as , , and . We examine the decay modes, and find that the branching
ratios can reach for the three decays, which should be accessible at
the Giga option of the ILC.Comment: 12 pages, 9 figure
ELM Characteristics in MAST
Edge localized mode (ELM) characteristics in a large spherical tokamak (ST) with significant auxiliary heating are explored. High confinement is achieved in mega ampere spherical tokamak (MAST) at low ELM frequencies even though the ELMs exhibit many type III characteristics. These ELMs are associated with a reduction in the pedestal density but no significant change in the pedestal temperature or temperature profile, indicating that energy is convected from the pedestal region into the scrape-off layer. Power to the targets during an ELM arrives predominantly at the low field outboard side. ELM effluxes are observed up to 20 cm from the plasma edge at the outboard mid-plane and are associated with the radial motion of a feature at an average velocity of 0.75 km s-1. The target balance observed in MAST is potentially rather favourable for the ST since H-mode access is facilitated in a regime where ELM losses flow mostly to the large wetted area, outboard targets and, in addition, the target heat loads are reduced by an even distribution of power between the upper and lower targets
Phenomenological Study of Strong Decays of Heavy Hadrons in Heavy Quark Effective Theory
The application of the tensor formalism of the heavy quark effective theory
(HQET) at leading order to strong decays of heavy hadrons is presented.
Comparisons between experimental and theoretical predictions of ratios of decay
rates for B mesons, D mesons and kaons are given. The application of HQET to
strange mesons presents some encouraging results. The spin-flavor symmetry is
used to predict some decay rates that have not yet been measured.Comment: 10 page
