The functioning of enzymes produces phenomena driving the processes which impart life to an organic system. The principal source of information about an enzyme-catalyzed reaction has been from analyses of the changes produced in concentrations of substrates and products. These observations have led to the construction of models invoking intermediate complexes of ingredients with the enzyme. One example is the Michaelis-Menten model, postulating an... 

Department of Public Information. Serves as UN public relations office. It is zealous in disseminating information about UN as an organization, but cannot be thought of as a source of information about individual countries or clearinghouse for information from abroad on any subject. 

This book is designed to be suitable for students and researchers. It is highly recommended as a reference book and for teaching the fascinating topics related to carbohydrates, heterocycles and organic synthesis. In addition to its importance in academia, it is also an excellent source for information about the variety of methods used in the synthesis of heterocycles important to industry. 

Crystals of several amino-acids and of a few simple peptides and other compounds related to proteins have been analyzed recently by three-dimensional methods. These and other accurate determinations of structure constitute the best experimental sources of information about the dimensions and configuration of the polypeptide chain. The present paper comprises a critical summary of this information— in particular, of the principal structural features of the amide group and the N—H---0 hydrogen bonds, as derived from X-ray diffraction analyses of crystals of amino-acids, peptides, and other organic compounds. 

Step 3. Conducting a Hazard Analysis The actual plan begins by defining the problems that may require emergency responses. The problem definitions result from a hazard analysis and identifying hazardous materials that could affect the community. There are many sources for information about hazardous materials. Included are local companies, users of materials, transportation organizations and companies, and waste handlers and disposers. For each hazardous material, analysts must determine the hazards and quantities present or potentially present in the community. The planning team must know the potential distribution media (air, water, sod, vehicles, rad, etc.) and how each potentially impacts community s residents. 

The At isotope may be separated by vacuum distillation. In general. At is chemically similar to iodine. Tracer studies (which are the only sources of information about the element) show that At2 is less volatile than I2, is soluble in organic solvents, and is reduced by SO2 to At which can be coprecipitated with Agl or TIL Hypochlorite, [C10], or peroxydisulfate, [S20g], oxidizes astatine to an anion that is carried by (e.g. coprecipitation... 

Ballast, D. K. 1998. The Encyclopedia of Association and Information Sources for Architects, Designers, and Engineers. Annonk, NY Sharpe Professional. In addition to listings of professional associations and organizations, this source includes information about journals, online databases, CD-ROMs, and federal government publications in the fields of architecture, design, and engineering. 

It is interesting in retrospect to look back on the points which emerged from these discussions as the basis around which the scientific program would be organized and the speakers chosen. We decided early on to focus on applications of these methods to provide information about polymer molecules and polymer systems The topics would all relate to the conformation and dynamics of macromoiecuies, or to the morphology of polymer-containing systems. Another important decision was to expand the scope of the ASI to include certain photochemical techniques, particularly laser flash photolysis. These applications were at the time quite new, but full of promise as important sources of information about polymers. 

Maintains a data base which collects and classifies all of the information about air toxics control programs submitted by federal, state and local agencies. The information is organized by agency, pollutant and emission source. Serves state and local agencies and the public. Monday through Friday, 7 30 a.m. - 5 00p.m., EST.
