that the recent outbreak of malaria around Nairobi has been caused by climate change,” it says. “In fact this probably has more to do with changes in drainage systems and population expansion. But in the Central Highlands the researchers have been able to rule these out and directly attribute the change to a 2oC rise in temperature.” The institute is using climate models to predict when epidemi...

Wastewater from the fertiliser industry is characterised by high chloride concentration, normally varying between 60 and 76 g/ l. Experiments with biological denitrification were performed in laboratory-scale ‘fill and draw’ reactors with synthetic fertiliser wastewater, with chloride concentrations up to 96.7 g Cl/l at 37°C; the pH was controlled in the range 6.8 to 7.2. Potassium acetate was ...

In the Fall of 2007, ten neuroscientists published a proposal for an interdisciplinary research initiative, the Decade of the Mind, that would focus on four "broad but intertwined areas": mental health, research on high-level cognitive functions, education, and computational applications (such as intelligent machines). I review the basic ideas behind the proposal and discuss the four proposed a...

As Hong Kong is a compact city with limited available land and high land prices, the construction of high-rise buildings is prevalent. The construction industry produces a significant amount of building waste. In 2005, about 21.5 million tonnes of construction waste were generated, of which 11% was disposed of in landfills and 89% in public filling areas. At the present rate, Hong Kong will run...

Two popular mounting positions of Doppler radar for human fall detection are in the ceiling center and at the torso level. This paper examines the fall signatures observed by a Doppler radar at the two positions and evaluates their consistencies with respect to the fall directions and locations. The complementary characteristics of the fall signatures motivate the integration of the features fr...

One way to compare different theoretical approaches the study of technologies is see what difference between their narratives construction a particular technology. In this paper, we re-narrate bicycle from perspective actor-network theory (ANT), comparing SCOT’s first account construction. Although SCOT has moved closer later by paying more attention co-construction and materliaty, Pinch Biker ...
