Specialist making plans is usually outlined as an task that's all for the rational allocation or exploitation of assets for man's greatest brief- and long term profit. The technology of. ecology is the examine of the fundamental parts of those assets (soil, water, air and so forth. ) and their inter relationships with residing organisms.

The particle beam is then passed through a detector that measures the energy that the particles lose as they pass through matter, and the larger the atomic number Z the larger is the loss. This type of apparatus gives a clean separation of 14 C from isotopes such as 14 N, 13 C, and 12 C. The carbon-13 isotope occurs naturally with a ratio of 1 to every 99 carbon-12 atoms. 1 Carbon-14 During photosynthesis, plants take up air with similar 14 C-isotope ratios11 as found 11 The ratio is de®ned as 14 C-isotope ratios and the expression for this ratio is: 14 14 C C À 12 C 12 C sample standard 14 C 14 Â 103 C 12 C standard Sec.

(b) therefore high numbers of these isotopes is a sign of recent exposure to cosmic rays. As several types of isotope concentrations depend on the exposure to cosmic rays, among other things, it may be possible to get a measure of how intense the high-energy particle bombardment has been in the past.
A classical example is Faraday's cage, which shields its interior from electrical disturbances outside. An electric current is nevertheless believed to be present in the solar interior to explain the Sun's general magnetic ®eld. 3. 4 The Sun's core The Sun may be thought of as being made up of several regions. The innermost part (r 0 to 175,000 km) of the Sun is called the core. The core is believed to extend out to around 25% of the Sun's total radius, and is the region where most of the energy production takes places.
