Using the World Wide Web to revolutionise technology transfer and training in the water and wastewater industries

Industry professionals of the near future will be supported by an IT infrastructure that enables them to complete a task by drawing on resources and people with expertise anywhere in the world, and access to knowledge through specific training programs that address the task requirements. The increasing uptake of new technologies enables information to reach a diverse population and to provide flexible learning environments 24 hours a day, 7 days a week. This paper examines one of the key areas where the World Wide Web will impact on the water and wastewater industries, namely technology transfer and training. The authors will present their experiences of developing online training courses for wastewater industry professionals over the last two years. The perspective is that of two people working at the coalface.

What happens after the swallow? Introducing the glottal release sound

Cervical auscultation presents as a noninvasive screening assessment of swallowing. Until now the focus of acoustic research in swallowing has been the characterization of swallowing sounds,. However, it may be that the technique is also suitable for the detection of respiratory sounds post swallow. A healthy relationship between swallowing and respiration is widely accepted as pivotal to safe swallowing. Previous investigators have shown that the expiratory phase of respiration commonly occurs prior to and after swallowing. That the larynx is valved shut during swallowing is also accepted. Previous research indicates that the larynx releases valved air immediately post swallow in healthy individuals. The current investigation sought to explore acoustic evidence of a release of subglottic air post swallow in nondysphagic individuals using a noninvasive medium. Fifty-nine healthy individuals spanning the ages of 18 to 60+ years swallowed 5 and 10 milliliters (ml) of thin and thick liquid boluses. Objective acoustic analysis was used to verify presence of the sound and to characterize its morphological features. The sound, dubbed the glottal release sound, was found to consistently occur in close proximity following the swallowing sound. The results indicated that the sound has distinct morphological features and that these change depending on the volume and viscosity of the bolus swallowed. Further research will be required to translate this information to a clinical tool.

Brazil's rise on the international scene: Brazil and the World

Since Cardoso and during Lula's Administration, the international order has undergone significant changes. These changes have allowed the Brazilian foreign policy to mitigate internal effects of an order established by others and, at the same time, to become an active participant in the formulation of the new order. To democratize globalization became the mainspring of Brazilian foreign policy. In the scope, President Lula has maintained the tradition of formulating and programming foreign policy as a State policy, and also has fostered the logistic strategy of incorporation of Brazil into the international scene.
