Theoretical Rheology, Polymeric Systems, Blood, Food, Other Specific Systems, Drag Reduction, Other Meetings, Geological Subjects —and titles appear within each section in alphabetical order. The abbreviations used for publishers names are well known in the book trade, and the information supplied should be sufficient for any reputable book supplier to obtain copies of the books listed. 

Estimates of the amount of natural gas available are made within the context of definitions and are subject to revision as definitions change, as additional information becomes available, as resources are consumed, or as undedyiag assumptions are altered. These definitions iaclude proved reserves where the resource is expected to be recoverable and marketable usiag known technology and prices probable reserves where a resource has been identified but not completely characterized and possible or potential gas where estimates are based on the available geological iaformation, historical trends, and previous successes. There are variations ia these definitions throughout the world. 

Physiographic development of the surface of the earth refers to the landforms and shapes of the landscape. These surface features are subject to continuous change from constructive (e.g., uplift, volcanic activity, and deposition of sediments) and destructive (e.g., erosion) processes. Landform modifications are continuous and sequential. These modifications establish a predictable continuity that can be helpful in determining certain aspects of relative geologic ages. 

The second major component of the education of a modern materials chemist in materials synthesis is, of course, in phase equilibria, possibly through the treatment of quaternary systems and P—T—X (pressure—temperature—composition) equilibria. This subject was essentially eliminated from chemistry departments and is taught in the materials and geological science departments. Every student (and professor) aspiring to be a materials chemist will have to master this subject. 

The most variable and site-specific factor is the reservoir rock matrix. Geologic formations vary greatly in chemical and physical properties depending on the conditions under which they formed and the geologic processes to which they have been subjected. 

It will, therefore, be seen that the best and safest practice is to use in each situation in the coal mine an explosive which is best adapted for the operation in hand. The use of unnecessarily weak explosives, even though apparently safer in some tests, is often a disadvantage and can be dangerous. These considerations have led to the development of a series of types of explosives suited for particular purposes in coal mines and subjected to tests relevant to their individual uses. Thus, in Britain there are now five classes of permitted explosives. In Germany there are three classes. In the U.S.A. geological conditions are different and the hazards are less than in Europe, and it has been possible to work throughout with the strongest types of permissible explosives. 

Until now, Mercury has only been studied more closely by one spacecraft (Mariner 10, 1974), since its nearness to the sun means that spacecraft approaching it are subject to particularly extreme conditions. NASA s MESSENGER (Mercury Surface, Space, Environment, Geochemistry and Ranging) was launched in 2004 and is planned to reach Mercury in March 2011, and then to orbit the planet. The main tasks of the MESSENGER mission are to map the planet, to make measurements of its magnetic field and to collect data relevant to its geological and tectonic history (Solomon, 2007). 

The geological cycle sediments from deep regions of the Earth, which are subject to high pressure and high temperature, are brought back to the Earth s surface by geological dynamics. The metamorphic rock is more labile than the starting material and can be leached more easily, so that a cycle is set up in which new clay species are formed. 

The assumptions of the radiocarbon method are widely known and understood (Table 1). Each has been the subject of review and comment over more than thirty years of 14C studies [1-3]1. Included in Table 1 under the heading contextual is an assumption sometimes not emphasized in discussions of the accuracy of 14C determinations. It is essential that the field archaeologist, geologist or geomorphologist document contextual relationships of sample materials with a closely defined cultural or geological event.
