recovery of metabolites from fermentation broth by solvent extraction can be used to optimize fermentation processes. end-product reutilization, low product concentration and large volumes of fermentation broth and the requirements for large bioreactors, in addition to the high cost largely contributed to the decline in fermentative 2,3-butanediol production. extraction can successfully be used...

This paper draws on La Via Campesina’s definition of food sovereignty and its potential for reconceptualising food as a basic human right within the dominant Australian food discourse. We argue that the educative value that emerges from urban food production in Australia stems from the action of growing food and its capacity to transform individuals’ social and environmental concerns over food ...

-The Tennagen test has been evaluated in "normal" subjects, patients with cancer (predominantly colorectal) and patients with non-malignant disease. The incidence of positive values was found to be higher in patients with clinically active cancer than in those with benign conditions or normal subjects. In our hands the test fell far short of the 9000 reliability previously claimed. This may be ...

This paper considers the survivability requirement for production operating systems that underlie typical information systems. Since economic incentives give competitive advantages to imperfect and therefore insecure software, it seems inevitable to consider retrofitting some form of security to existing systems. This approach has long been anathema in the security community. We outline the pra...

By applying the latest developments occurring in photogrammetry to the map production systems, important reductions in map production costs are obtained. For instance, by starting to use digital cameras and GPS/IMU systems in taking aerial photographs and in aerial triangulation, there is an opportunity of reducing the number of ground control points that must be established due to map producti...

This research examines the adoption of information technology in small and medium sized enterprises in Japan. SMEs comprise more than 99 percent of the total Japanese enterprises. These one million-plus businesses employ 72.7 percent of workers and account for more than 50 percent of the total value and almost 60 percent of the value added. SMEs are not only a crucial source of employment, but ...
