in recent years there have been many attempts to develop and market inexpensive mixtures of high protein food for the children in developing areas of the world. biological studies have shown that these foods are rich sources of protein and are every effective in combating protein malnutrition. however, practical marketing and distribution has not been very successful due to the local people's h...

We are given a trajectory T and an area A. T might intersect A several times, and our aim is to detect whether T visits A with some regularity, e.g. what is the longest time span that a GPS-GSM equipped elephant visited a specific lake on a daily (weekly or yearly) basis, where the elephant has to visit the lake most of the days (weeks or years), but not necessarily on every day (week or year)....

Protected Areas (PAs) are fundamental for biodiversity conservation, for the provision of ecosystem services, and for tourism. In Africa, they are subject to increasing pressures of two kinds: objective factors, like high human fertility rates, that are generally not open to human manipulation, and subjective factors that are under human control. A major subjective component has been reduction ...

Two families of general affine surface areas are introduced. Basic properties and affine isoperimetric inequalities for these new affine surface areas as well as for Lφ affine surface areas are established. 2000 AMS subject classification: Primary 52A20; Secondary 53A15. Finding the right notion of affine surface area was one of the first questions asked within affine differential geometry. At ...

Circumpolar areas are associated with prolonged cold exposure where wind, precipitation, and darkness further aggravate the environmental conditions and the associated risks. Despite the climate warming, cold climatic conditions will prevail in circumpolar areas and contribute to adverse health effects. Frostbite is a freezing injury where localized damage affects the skin and other tissues. It...

Wild life: The elusive fosa (Cryptoprocta ferox) is the top predator in the dry deciduous forests of Madagascar, but very little was known about its biology until the 1990s. The presence of volunteer groups studying its role in the forest’s ecology has also helped to protect its habitat. (Photo: Earthwatch/ Luke Dollar.) The world’s latest national park has just been created in the east of Russ...
