to localized spectroscopy (2) and chemical shift imaging (3) that are applicable to many chemical species, MRI of water protons has been functionally extended to NMR angiography (4), perfusion imaging It has previously been demonstrated (8, 9) that the presence of deoxyhemoglobin in blood changes the proton

and Hayward (3), which showed an increase in BrAC of 8.62 % for each 1°C increase in body temperature. This study is, however, problematic in a number of areas because of the artificial nature of increasing body temperature by immersing the nine male subjects up to their necks in stirred water heated up to 42

if exposed to small slight increases (1-2oC) in water temperature and experience coral bleaching. Coral bleaching occurs when the photosynthetic symbionts of corals (zooxanthellae) become increasing vulnerable to damage by light. The resulting damage leads to the expulsion of these important organisms from

We:introduce the concept of soft objects whose shape changes in response to their surroundings. Established geometric modelling techniques exist to handle most engineering components, including 'free form ' shapes such as car bodies and telephones. More recently, there has been a lot

or drinking water containing 40 mg/L. Adverse effects in sensitive mammals were observed at dietary levels of 85 -100 mg/kg ration and higher or 100 mg/L in drinking water. Acute oral LD50 values for sensitive species of birds were near 200 mg/kg body weight and, for mammals, 22 -35 mg/kg body weight. Humans

, and a distance-dependent dielectric constant is used to approximate the charge--charge interactions in solution. The resulting EEF1 is subjected to a number of tests. Molecular dynamics simulations at room temperature of several proteins in their native conformation are performed, and stable
