The strategy, which represents the Government of Ghana’s vision of ‘creating an all-inclusive society through the provisi...

The number of studies on extremophilic organisms has grown exponentially in the last few years. These exotic organisms (extremoplilees) are adapted to living at 100 c. In volcanic springs, at low temperatures in the cold polar seas, at high pressure in the deep sea, at very low and high ph values (ph 0-1 or ph 10-11) or at hight salt concentration (35%). Recent developments clearly show that ce...

We analyze an epidemiological model consisting of a linear chain of three cocirculating influenza A strains that provide hosts exposed to a given strain with partial immune cross-protection against other strains. In the extreme case where infection with the middle strain prevents further infections from the other two strains, we reduce the model to a six-dimensional kernel capable of showing se...

The erosion-corrosion environments found in fluid conveying components such as pipelines, pumps, agitators and chutes have important implications for both service life and maintenance cost. The destructive synergy wrought when corrosion occurs in combination with erosion can be many times greater than the sum of each mechanism acting in isolation. A factory applied coating, if present, will hav...

Dengue fever is a major health problem in Vietnam, but its incidence differs from province to province. To understand this at the local level, we assessed the effect of four weather components (humidity, rainfall, temperature and sunshine) on the number of dengue cases in nine provinces of Vietnam. Monthly data from 1999 to 2009 were analysed by time-series regression using negative binomial mo...

BACKGROUND Cycling has the potential to provide health, environmental and economic benefits but the level of cycling is very low in New Zealand and many other countries. Adverse weather is often cited as a reason why people do not cycle. This study investigated temporal and seasonal variability in cycle volume and its association with weather in Auckland, New Zealand's largest city. METHODS T...
