The Fiftieth Gate : an Australian case study in twentieth-century 'popular' publishing

On Sunday 6 April 1997, historian Mark Baker's first non-academic book was launched at Melbourne's iconic migrant portal, Station Pier. The guest list of over 500 invitees included representatives of many print media organisations, most of whom interviewed the author. His photograph was reproduced a week later in the 'Agenda' section of The Age newspaper. In this portrait, Baker leans on the railings beside the massive structure of Station Pier. Framed by sea and sky, he is caught glancing pensively over his shoulder past the camera and into the middle distance. He is alone. The day is bleak. Here, the reader is invited to surmise, is a man with much on his mind. In a flash of inspiration the sub-editor has prefaced the accompanying caption, 'Back to the future', linking the story with the mass media of film and television.

Bi-cultural consultant is your key to the red gate

Chinese market is a uniquely challenging market to Western businesses. The difference is its uniqueness which majority of the organisations have been struggling with. Research has proven that cultural difference is the main barrier to success in China. Where companies are caught by surprise is the large gap between the two cultures. Standard training simply does not cut it.

Design of a high sensitive double-gate field-effect transistor biosensor for DNA detection

The study of interactions between organic biomolecules and semiconducting surfaces is an important consideration for the design and fabrication of field-effect-transistor (FET) biosensor. This paper demonstrates DNA detection by employing a double-gate field effect transistor (DGFET). In addition, an investigation of sensitivity and signal to noise ratio (SNR) is carried out for different values of analyte concentration, buffer ion concentration, pH, reaction constant, etc. Sensitivity, which is indicated by the change of drain current, increases non-linearly after a specific value (∼1nM) of analyte concentration and decreases non-linearly with buffer ion concentration. However, sensitivity is linearly related to the fluidic gate voltage. The drain current has a significant effect on the positive surface group (-NH2) compared to the negative counterpart (-OH). Furthermore, the sensor has the same response at a particular value of pH (5.76) irrespective of the density of surface group, although it decreases with pH value. The signal to noise ratio is improved with higher analyte concentrations and receptor densities.
