  • In November 2003 the Road Pavement Forum resolved that a technical working group should be formed to investigate the development of a national guideline (or code of practice) on the use of Asphalt Reinforcement. For the purpose of this study the main functions of Asphalt Reinforcement Interlayer (ARI) is to:prevent or reduce reflective cracking from underlying layers,protect asphalt layers against traffic induced cracking,avoid or reduce development of rutting in asphalt layers.

  • Aluminium alloys have undergone a dramatic transformation in areas of extrusion, machining, welding, heat treatment, structural changes, created by ultra fine particles and enhanced corrosion resistance. Hence, these alloys have made rapid gains in European automotive and space industry. These developments have been described by experts in the book with new data and attractive graphics. The effect of processing parameters, including welding and deep rolling on their performance have been highlighted to alleviate the concerns of manufacturers and designers for new applications.

  • Viewed from above, the city of Mataram appears as a patchwork of green fields, and red and brown rooftops, strategically clustered around gleaming white mosques. Plots of water spinach and wet rice are dotted throughout the city and still feed many of its people, despite the steady encroachment of housing and commercial developments. Horse-drawn carts carry people along dusty laneways, to and from school, work and the neighbourhood markets, and up to the main thoroughfares where mini buses run the length of the city. Mataram is hot and humid, or hot and wet.

  • Under moderate conditions the body automatically adjusts itself to keep its temperature within safe limits. Sweating is the body's most efficient means of getting rid of heat, but the more humid the air, the harder it is for sweat to evaporate and the harder it is for the body to cool off. Under hot and humid conditions, work becomes harder because much of our blood is going to the surface of the body, and less is available to the active muscles. Loss of salt from sweating can result in fatigue.

  • Many Roman villas had under-floor heating which would have been especially useful in the British winter! The Roman name, hypocaust, is Ancient Greek meaning ‘fire beneath’. The floor was supported on short columns made of stacked tiles. A fire would be kept burning (very hard work for the slaves!) in the furnace room, and the hot air would move through the under-floor area, heating the rooms above. The hot air and smoke escaped through channels in the walls. To make your hypocaust system, you will need to raise up your whole villa by around 6cm.

  • The recent proliferation of elec¬tronic databases and powerful search engines will undoubtedly permit the antedating of many of the entries. Individualised dating research, such as Allen Walker's hunt for the origin of 'OK' or Barry Popik's exhaustive work on terms such as 'hot dog', produces dramatic antedatings: we could not undertake this level of detailed research for every entry.

  • I've been watching this show lately with my 6-year-old son, Austin, who likes learning about space and planets and black holes and stuff. It's called How the Universe Works. And man, the universe has one hell of a story to tell. It all starts with, presumably, the Big Bang, wherein a single point in space barfs forth a hot, violent soup of particles and energy that take a few hundred million years just to cool down enough to begin coalescing into stars. You know... to "cool down" enough to become giant fucking balls of fire. Stars ignite. Star clusters form,...
