Naturally occurring monoterpene alcohols were heated in water without prior deriva-tization with typical biological water-solubilizing groups such as phosphates or glyco-sidic units. Biomimetic reactions that normally would be acid-catalyzed, proceeded on the underivatized compounds in the absence of added acidulant. Cooling of the mixtures rendered the products insoluble, readily isolable and the aqueous phase did not require neutralization before workup.

At present, most PET scanners can acquire in both a two-dimensional as well as a three-dimensional mode, whereas SPECT cameras measure in a three-dimensional mode. The physical property of the dual-positron gamma-rays emission lends itself to mathematical reconstruction algorithms to produce three-dimensional images in which the calculations are much closer to exact theoretical ones than those of SPECT. This is, in part, due to the two-photon as opposed to single-photon approach. PET can now achieve resolutions, for example in animal-dedicated scanners, in the order of 1 or 2 mm. The resolution is inherently limited theoretically only by the mean free path or distance in which the positron travels before it annihilates with an electron, e.g. those in biological water 2-8 mm. SPECT, although achieving millimeter resolution with the appropriate instrumentation, cannot quite achieve these levels.

MiKIE is a mobile, modular biological water treatment technology used for the treatment of organic contaminants. The system was developed and patented by John D. Bogart and is commercially available from Bogart Environmental Services, Inc. According to the vendor, the MiKIE system has been in use for water decontamination on several sites for nearly 5 years. 

The great solvent power of water, especially for ionic compounds, is due to its dielectric constant. If this were only, say 10, instead of the actual 80, it would mean that water could dissolve only a trace of sodium chloride. This solvent action of water., naturally. plays an important role in geology. In biology, water functions as a means of conveying salts and other substances which circulate in the bodies of animals and plants. It is outside the scope of this book to discuss any further the function of water on this planet, a subject which could fill many volumes. It is important in this context that we now know water molecules to possess a dipole moment and to discover whether perhaps this fact can provide an explanation of the unique properties of water. 

Figure 1 shows that the decay resistance of acetylated wood is directly proportional to the WPG (26). The degree of dimensional stability is also proportional to the WPG so the exclusion of cell wall or biological water may be a very important factor in the decay resistance mechanism.

Finally, the question of the structure of biological water is one of far-reaching importance. Some workers in the last few decades have suggested that water in biological systems is special but our answer is that this special structure is so readily explicable that no mystery exists. Biological cells are sized on the micron scale and contain much soiid material. The surface-to-volume ratio inside such cells is very large. Most of the waters in cells are in fact surface waters. In this sense, biologicai water is special but only because it has lost the netted-up properties of bulk water and adopted the individual two-dimensional structure of water at all surfaces. 

Several 3d, 4d, and 5d transition ions were tried, all at fixed pH (6) and fixed concentration withont success. It appears that manganese may be tmly nniqne for biological water splitting.

The /3-hydroxy aldehydes and -hydroxy ketones formed in aldol reactions x U P can be easily dehydrated to yield conjugated enones. In fact, it s this loss of Biological water that gives the aldol condensation its name, since water condenses out Connection of the reaction when the enone product forms.
