Incidence of flood has been on the increase in Ilorin for sometime; and this exemplifies the problem operating in most urban centres in Nigeria. Increase in runoff production in an urbanized catchment is a function, among other factors of to increase in percentage paved area brought about by deforestation activities and poor environmental attitude of the people. This study examines the relationship between runoff discharge and basin characteristics in Ilorin. Data used were collected directly from the field over a period of one calendar year. Rainfall data were collected in each basin using a standard rainguage of 20cm orifice while basin discharge was collected twice daily (8.00am and 6.30pm) using fabricated staff gauge graduated in centimeter. Basin morphometric attributes were compu...

There are few companies supplying map data for navigation systems. Two of the big ones are Tele Atlas and Navteq. They produce digital maps for all types of systems, including cell phones, portable GPS units and navigation systems. Tele Atlas is based in Europe and has coverage in more than 200 countries and maps more than 20 million kilometres of road and 845 million addresses. Navteq has their global headquarters in Illinois and claim coverage on six continents. Both have offices around the world and their maps are continually updated. I have trouble keeping even my bank book up to date! The GPS signal comes from overhead satellites in synchronous orbit and is received by a special GPS antenna on the vehicle. This antenna must have a view of the sky unobstructed by metal or tall build...

Using those data, scientists extrapolated to the rest of Manitoba's southwestern corner. That's the area known as the "prairie pothole region" -- a collection of ponds, bogs and marshes, many no bigger than your living room and many that have been bled dry by farmers who dug long trenches to drain the wetlands into a ditch or nearby creek. You gotta marvel at that, really," [Shane Gabor] said. "The market is telling these farmers that wetlands aren't valuable. But they are. Then, respondents were presented with five scenarios to save wetlands. How much would their household be willing to pay a year to stop the degradation of the remaining wetlands? Restore the wetlands to 83 per cent of 1968 levels? 100 per cent? Each scenario came with a list of byproducts, such as the impact on wat...

The federal government has a $13.8-billion federal surplus, yet the Department of Indian and Northern Development's (INAC) Manitoba Region is unable to fund schools and health needs for Manitoba's First Nations. The reason, we are repeatedly told, is that INAC's Manitoba region is in a deficit position. It just doesn't have the funds. In the caption to the photo accompanying the article on Russia's launch of Sputnik in October 1957, it says this satellite was "the first man-made object to reach the limits of the earth's gravity." This is an erroneous statement. If it were so, the moon would not orbit the Earth. Rather, there is a balance between the centrifugal force outward of both the satellite and the moon, and the force of gravity inward. Indeed, mathematically speaking, there is no...

Griffiths discusses whether the undoubted thinning of sea ice in the various waterways that make up the Northwest Passage will produce not only an increase in intercontinental shipping, but a shipping-based challenge to Canada's sovereignty over its Arctic waters. Griffiths argues that climate change presents no serious sovereignty problem in the Northwest Passage where commercial navigation is concerned. However, Canadians may well have a need to prepare for new security and environmental challenges associated with a gradual increase in summer-months foreign shipping, which offers little or no challenge to Canada's occupancy of the high Arctic Archipelago.

What's new? As the name suggests, the iPhone 3G takes advantage of [Rogers]' HSPA ("Vision") 3G network for broadband-like cellphone speeds across Canada. This means you can surf and download without having to find a wireless hot spot (though Wi-Fi is still included in the new iPhone, and is generally faster than 3G). Built-in GPS technology and the Google Maps application mean the iPhone can help you get to where you're going -- even with satellite photo views on its bright 8.75-centimetre screen. And it's not just for navigation to your destination, but to spots in between such as restaurants, bank machines or gas stations. Feel like a cup of joe when you're walking around town? Use your fingertip to type the word "coffee" in the search field and you'll see push-pins near your locati...
