In this issue, Jeanne Mager Stellman of Columbia University's Mailman School of Public Health and colleagues describe a new research tool: software that incorporates relational database technology, geographic information system (GIS) principles, and refined

mathematical models to create "exposure opportunity" scores from military data on spray missions [EHP 111:321-328].

Long ignored as an important but uninteresting branch of topology, knot theory is now used in descriptions of weather systems,

mathematical models used in physics, and even the study of DNA.

Research will focus on developing new tailor-made

mathematical models based on practical issues, taking into account the chemical, sensory, engineering, mathematical and statistical properties of a product at different stages in the production chain.

The math modeling course, for example, teaches students to solve practical problems using

mathematical models and MATLAB.

Explorations of

Mathematical Models in Biology With Maple

The systematic procedure described here can be used to construct

mathematical models of any macroscopic, physical, chemical, or biological system.

For processing the presented above

mathematical models it is important the variation law of the angle of the pair [O.

Contributors look at

mathematical models for the flow of biological heat, and sometimes the flow of fluids that contain the heat.

We use

mathematical models to predict the potential public health impact of new TB vaccines in high-incidence countries.

Jang and her colleagues are now using their test results to develop

mathematical models of aerosol production.

Key words: Cryptosporidium, epidemic, Giardia, infectious disease,

mathematical models, waterborne pathogens.

More immediately, the researchers want to develop and verify

mathematical models of heat and mass transfer of food elements dried in superheated steam (SS).
