Database Physical properties

The model contains a surface energy method for parameterizing winds and turbulence near the ground. Its chemical database library has physical properties (seven types, three temperature dependent) for 190 chemical compounds obtained from the DIPPR" database. Physical property data for any of the over 900 chemicals in DIPPR can be incorporated into the model, as needed. The model computes hazard zones and related health consequences. An option is provided to account for the accident frequency and chemical release probability from transportation of hazardous material containers. When coupled with preprocessed historical meteorology and population den.sitie.s, it provides quantitative risk estimates. The model is not capable of simulating dense-gas behavior. 

The Chemical Information Sources Wiki (http //cheminfo. informatics.indiana.edu/cicc/cis/index.php/Main Page) is a guide to the many sources of reference materials available for those with questions related to chemistry. The site includes information on primary, secondary, and tertiary pubheation sources, chemical information databases, physical property information, chemical patent searching, and molecular visualization tools and sites. The material is based on an undergraduate course offered for many years in the Indiana University Department of Chemistry by Gary Wiggins. 

Gmelin contains over 800 different chemical and physical property fields, and a detailed index of the original literature. Broad categories of data found in the database include ... 

OtherD t b ses. Available from different vendors (Table 8). For example, the researcher can obtain physical properties by usiag the Merck Index Online or the Dictionary of Organic Compounds available by Chapman and Hall Chemical Database. In DIALOG, numeric databases are collected under the name of CHEMPROP. 

An extensive pesticide properties database was compiled, which includes six physical properties, ie, solubiUty, half-life, soil sorption, vapor pressure, acid pR and base pR for about 240 compounds (4). Because not all of the properties have been measured for all pesticides, some values had to be estimated. By early 1995, the Agricultural Research Service (ARS) had developed a computerized pesticide property database containing 17 physical properties for 330 pesticide compounds. The primary user of these data has been the USDA s Natural Resources Conservation Service (formerly the Soil Conservation Service) for leaching models to advise farmers on any combination of soil and pesticide properties that could potentially lead to substantial groundwater contamination.

The DIPPR databases were developed in the United States by the Design Institute for Physical Properties of the American Institute of Chemical Engineers. The DIPPR projects are aimed at providing evaluated process design data for the design of chemical processes and equipment (www.aiche.org/dippr/projects.htm). The Project 801 has been made available to university departments see Rowley et al. (2004) and http.//dippr.byu. edu/description/htm. 

An important issue in 2D liquid separations is finding a first dimension, which can provide information on the p7 of the protein. This is important as p7 information has biological significance in proteomics where it is a physical property listed in the databases and can aid in protein identification. The use of p7...

Equilibrium combustion product compositions and properties may be readily calculated using thermochemical computer codes which minimize the Gibbs free energy and use thermodynamic databases containing polynomial curve-fits of physical properties. Two widely used versions are those developed at NASA Lewis (Gordon and McBride, NASA SP-273, 1971) and at Stanford University (Reynolds, STANJAN Chemical Equilibrium Solver, Stanford University, 1987). 

Specialized properties that are not covered in these standard databases can be found in specialized books. The properties of food can be found in Physical Properties of Foods (Peleg and Bagley 1983). The properties of many petroleum products can be found in Petroleum Products Handbook (Guthrie 1960). The Merck Index (1996) lists chemicals, drugs, and biologicals.
