No full textCumulative Trauma Disorders: Their Recognition and Ergonomic Measures to avoid them
No full textCumulative Trauma Disorders (CTD) refers to a large category of disorders of the muscles, tendons, or nerves and are the summary results of microtrauma caused, precipitated, or aggravated by repeated exertion or movements of the body. They go by many names in the literature. They have become a matter of urgent ergonomic concerns for manufacturers, insurance companies, health care provides, and government agencies. Since CTD are usually caused by repeated and/or forceful exertions, often in the hand-arm-shoulder region. They predominantly occur to soft tissues, such as tendons and ligaments, and to nerves and blood vessels. They are commonly associated with certain occupational and leisure activities. Many CTD can be avoided by a set of fairly simple and straightforward ergonomic procedures. In this presentation, the author will share his views on the epidemiology, pathogenesis and treatment including the ergonomic measures to avoid CTD
How Hong Kong students learn using the study process questionnaire: Cross-cultural comparisons
No full textAnecdotal evidence abounds in Hong Kong to the effect that students entering tertiary education are predisposed to a “rote” learning approach. Until the research studies at City Polytechnic of Hong Kong and Hong Kong Polytechnic, there have been no systematic studies performed locally and as such in the absence of cross-cultural research, there is a tendency to rely on anecdotal statements about Hong Kong students’ approaches to learning. This study was designed to see if Hong Kong Chinese students predisposed to a surface or deep approach to learning react differently when moving progressively from one stage to the next stage in their undergraduate occupational therapy curriculum. This study adopted a longitudinal design method which followed a cohort of 80 undergraduate occupational therapy students over two years and measured their changes in their approaches to learning using the Biggs’ Study Process Questionnaire The internal consistency reliability estimates alpha for SPQ scales for samples of Hong Kong, Australian and British students was compared. The alpha estimates of this study varied from 0.56 to 0.75 which compares favourably with other studies reported in Hong Kong, Australia and U.K. The results of this study indicated that the Hong Kong Chinese students demonstrated a higher mean for the deep approach to learning (47.3 in Year 1 and 46.3 in Year 3) and a lower mean for the surface approach (42.7 in Year 1 and 42.4 in Year 3), similar to other Hong Kong studies from other tertiary institutions in Hong Kong and Australia. From the findings, it is reasonable to conclude that students change their approach according to the different demands imposed by their varied learning needs. Based on this belief, the author while ruling out the potential for misunderstandings about Asian students, draws attention to the cross-cultural differences in approaches to learning which highlights on the changing nature of tertiary classroom and the implications for teaching and learning, with the major shift in the characteristic of student population

Ecological Systems Thinking
No full textWhile the science of ecology has expanded markedly in the past century, that knowledge has not significantly changed the pace of economic growth or deflected the momentum of human expansion. Warnings, including that from the Millennium Ecosystem Assessment team, multiply but without a corresponding societal response. The author traces the problem to the realm of politics and the ineffectiveness of statutes such as the National Environmental Policy Act. The article ends with suggestions about how to extend science more effectively into the political realm. © 2019 Elsevier B.V. All rights reserved
Flame-wall interaction at enhanced turbulence intensities as characterized by ultrafast 1d-cars thermometry
No full textIn practical combustion-based devices, such as internal combustion (IC) engines and gas turbines for power generation, there exists significant interaction between gas-phase combustion and metal surfaces. The nature of this heterogeneous interaction is complex, involving both physical and chemical effects. The metal surface is generally much cooler than impinging flames, and significant heat flux to the metal wall ensues during the flame–wall interaction (FWI). In this work, we investigate FWI in the side-wall quenching canonical configuration obtained with two-beam femtosecond/picosecond 1D-CARS thermometry. The experiments are performed using a generic burner where the turbulence intensities are significantly enhanced by the employment of a turbulence generator grid (blockage 45%). Previously, these operating conditions have only been well-characterized at quasi-stationary conditions (Re = 5000) [Bohlin, A., Jainski, C., Patterson, B.D., Dreizler, A., Kliewer, C.J.: Multiparameter spatiothermochemical probing of flame–wall interactions advanced with coherent Raman imaging. Proc. Combust. Inst. 36, 4557–4564 (2017)]. In these new experiments, complex interplay between the laser diagnostic and the turbulent combustion in the near wall region is overcome, and data is produced, for instance, on the maximum instantaneous temperature gradients versus the position of the flame-front near the wall as determined with direct thermometry contour analysis.Flight Performance and Propulsio

Etude d'un écosystème lacustre en région méditerranéenne: l'étang d'Entressen (B.d. R., France). 1. Hydrologie, hydrochimie
No full textThe study concerns a lake-ecosystem of french mediterranean country : the Entressen lake. It présents a great originality that of to undergo for a several years the impacts of the abundant birds colonies which frequent it regularly. These colonies are bound up with dumping-ground of garbage from Marseille (dumping-ground situated at 1 km-S.W.).
The water physical and chemical characteristics are studied. The analyses show a large tendency to eutrophisation of this lake. The author studies also the hydrology and proposes a better water management.L'étude porte sur un écosystème lacustre en région méditerranéenne française : l'étang d’Entressen. Ce biotope présente une grande originalité celle de subir depuis plusieurs années des impacts dus à d’abondantes colonies d’oiseaux qui le fréquentent régulièrement. Ces colonies sont liées à la décharge d’ordures ménagères de la ville de Marseille (décharge située à 1 km au S.O.).
Les caractéristiques physiques et chimiques des eaux sont étudiées. Les analyses montrent une nette tendance à l'eutrophisation de cet étang.
