The resins are substances derived mostly from vegetable sources some have been used as binders in the preparation of paints and varnishes, others as incense burned in ritual ceremonies, and a few, such as amber, have been used on their own, as semiprecious stones. It should be noted, however, that since the midtwentieth century the term resin has acquired a new meaning that of a synthetic pliable "plastic" material that can be shaped, mostly when hot. Synthetic resins are used mainly for packaging and for making textile fibers and automobile parts. In the discussion that follows the term resin is used to refer only to resins of natural origin (Serpico and White 2000a Parry 1918). 

Bacterial spores have been deliberately taken into space, in particular spores of the bacterium Bacillus subtilis. Up to 70 per cent of the bacterial spores survive in the short term for approximately 10 days of exposure to space vacuum. The chances of survival in space are increased if the spores are embedded in chemical protection such as sugars, or salt crystals, or if they are exposed in thick layers. For example, 30 per cent of B. subtilis spores survived for nearly 6 years in space when embedded in salt crystals and 80 per cent survived in the presence of glucose. Bacillus subtilis spores in Dominican amber have remained viable for several million years. Transport to a friendly environment with a source of energy is all that is required for life to be seeded on this planet or the next.

In contrast to the diversity in compositions encountered in the unrelated specimens above, all 45 samples of uncolored or amber glass with grisaille painting from the Chateau of Rouen were basically similar in composition. This glass contains about 15% potassium oxide and only about 3.5% sodium oxide (see Table II). Because these similar specimens came from the same building, a common source of manufacture seems likely. These data therefore support our belief that individual sources of glass produced compositionally consistent products. 

Most force fields used in coordination chemistry, in respect of the organic part of the molecules, are based on or are at least similar to the MM2 11 or AMBER 11 parameterization schemes, or mixtures thereof. However, it is of importance to stress again that transferring parameters from one force field to another without appropriate checks is not valid. This is not only a question of the different potential energy functions that may be used, but it is also a consequence of the interrelatedness of the entire set of parameters. Force field parameters imported from any source, whether a well-established force field or experimental data, should only be used as a starting point for further parameter refinement. 

YETI [198] is a force field designed for the accurate representation of nonbonded interactions. It is most often used for modeling interactions between biomolecules and small substrate molecules. The molecular geometry optimization for the component molecules is not previewed so that it has been obtained from some other source, such as AMBER. Then YETI is used to model the docking.
