Bowie as a conduit

...2 is a sequence of abstract instrumentals – itchy guitar lines and synthesizers fidget over troubled, would-be soothing xylophones. This was a route to modern classical music as it mimics the minimalism of Steve Reich and Philip Glass. Lyrics (where they appear) are patches of non-sequiturs which hint at depression, failing relationships, an inability to hold the bits...

How are drones keeping track of songbirds?

...2. They first conducted trial runs on local college athletic fields to help refine their methods, and then field-tested the technology in real bird surveys on Pennsylvania State Game Lands. “We counted birds at 51 locations using standard point counts (me counting birds for five minutes) and flew drones with recorders over the same locations on the same day,” says...

The devil is in the (complex) detail

...2 years of negotiation time to thrash out the issues - and with the polarisation of issues taking place via the group pressures operating within the UK government, are the ideal conditions for making decision-making biases more likely. The implications for the process of negotiation are that biases may result in options not being fully considered before or during...

Climate change is triple risk to Europe

...2°C by 2100, temperatures will almost every year tip to 40°C in many parts of Asia, Australia, North Africa, and both North and South America, and in Europe there will each summer be a 30% probability of similarly strong heatwaves. And with such high temperatures comes the increased risk of other climate-related disasters. Another team of European researchers warn in...

Injection moulding

...2 weeks of production time per year can be saved. [Diagram of an injection moulding cycle] Cycle times for reinforced thermosets are usually longer than for thermopolymers, although 30% better than in compression moulding and result in less porosity. Yields are high, varying from 95–99%. although the process is only 25–40% energy efficient. Due to the high capital...

Plasma arc welding

...gases. Design: Very thin sections can be welded by plasma keyhole welding. Minimal distortion occurs during keyhole welding of aluminium alloys (butt joints): mismatch on 6 mm plate = 2 mm max. root gap of 6 mm plate = 1 mm max. Bead appearance is excellent. Low porosity welds achievable. See Also: Gas shielded arc welding (TIG/MIG/MAG) and Manual metal arc welding (MMA)....

Fluid and Rubber Die Forming (Guerin and Hydroform)

...2 x 3 m2. Sheet blanks can be pre-heated for forming by the use of an infrared heating chamber. Fluid forming presses use pressures up to 200 MPa and blank diameters up to 1900 mm. Material thicknesses range from 0.1 to 16 mm. Draw ratios up to 3:1 are possible. Materials: Almost any kind of sheet metal can be rubber or fluid die formed. Materials that can be rubber die...

Climate change in the global South: Bangladesh and Senegal

...2 Transcript The third film examines the threat posed by climate change to Saint-Louis, a coastal city in north Senegal. Because much of Saint-Louis was built on low-lying land, it is under threat from rising sea levels, storm intensification and the increased risk of flooding. In Saint-Louis, dykes have been built to protect the city from the river when it swells due to...
