...chemistry, but different sizes and physical constructions will lead to some differences. Likewise for all NiMH batteries, or any other chemistry. Some basic data on specific examples of each of these four batteries is given in Table 1.

...chemistry community. In addition, there is the implication that this information has been obtained from a specific source (e.g. the specific study on these samples), and as such, it should be accompanied by a reference. The correct way to show this statement in an answer would therefore be: Analytical tests on samples of Greco-Roman cosmetic powders have revealed that the...

...chemistry or for other reasons, there is evidence that the majority of pet owners see their animals as part of the family. “This doesn’t mean they regard them as humans,” says Professor Nickie Charles, a University of Warwick sociologist with a particular interest in animal–human relationships. Close links with animals are often in addition to rather than instead...

Introducing consciousness

...chemistry and physics. Reproduction, for example, counts as a high-level phenomenon, which can be explained in terms of more basic genetic and cellular processes, which can themselves be explained in chemical and physical terms. This sort of explanation, where a phenomenon at one level is explained in terms of those at a lower level, is called reductive explanation. The...

...chemistry teacher who lives in the Maldives, has navigated three difficult – and very different – pregnancies. Shifneez has a severe form of sickle-cell disease, an inherited disorder that causes her red blood cells, which are normally plump and round, to transform into a crescent shape. These deformed blood cells can clog the circulation, starving the body’s...

Sir David Attenborough - Earth in Vision

...chemistry doesn’t get as big an audience as a programme on a chimpanzee community.’ But that’s what public service broadcasting should be about. I personally think that the idea of trying to define a public service programme is a nonsense. What defines public service broadcasting is a schedule and a rounded schedule, and you judge your success as a public service...

An introduction to energy resources

...chemistry of the atmosphere with plant and animal chemistry. The carbon taken from the atmosphere (fixed) by plants enables them to grow, but in addition much of it enters the food chain as either living or dead material. Living plants are eaten by herbivores which themselves may become food for carnivores. The dead material provides food for the decomposers (bacteria and...

Effects of pollutants on the aquatic environment

...chemistry, biology and physics. Apart from keeping us alive, water is used extensively in industrial processes, for recreation and for transport. It is something we can’t do without. The water we use for domestic purposes ought to be free from contaminants, yet water pollution is a major problem in many countries. According to the World Health Organization (WHO, 2002),...
