Rations ‘Hot Climates’
vanBoxtel, L. B. J.; opdeWeegh, M. J.; June 2004; 73 pp.; In Dutch
Contract(s)/Grant(s): A03/KL/115; TNO Proj. 010.53232
Report No.(s): TD-2004-0268; TNO-Voeding-V5814; Copyright; Avail: Other Sources
A concept of a new designed individual combat ration, to be used in hot climate operations, was evaluated and discussed
in a panel consisting of 10 soldiers very experienced in training and missions under hot weather conditions. Based on the
discussions and findings the concept of the ration was redesigned. The rations have to fulfill the expected nutritional
requirements and energy expenditure during activity and/or action in hot weather climates. The expected logistic operations
of the rations (central stocking, transport, local stocking et cetera) and the temperature load during life time of the rations were
considered and limited the use of certain products to be incorporated in this type of ration. For two products (peanut based
snacks) an in-depth study was done with respect to the feasibility to increase the standard guaranteed shelf-life of 6 months
up to the needed 2-years period. Measures studied were: 1. Stringent selection of initial product quality and 2. Excluding
oxygen in package (oxygen scavenger; 100 % nitrogen atmosphere; high barrier packaging film). For one of the products a
shelf-life up to 2 year in moderated temperatures (20 - 30C) could be achieved and the product could even withstand
temperature abuse of 55C up to 4 months.

Novel Computational Approaches Using Biotechnology Information for Chemical Toxicity Prediction
Judson, Philip; Mar. 26, 2004; 38 pp.; In English; Original contains color illustrations
Contract(s)/Grant(s): FA8655-02-M4027
Report No.(s): AD-A425441; EOARD-SPC-02-4027; No Copyright; Avail: CASI; A03, Hardcopy
This report results from a contract tasking Lhasa Limited as follows. The contractor will investigate techniques to apply
computational methodologies and biotechnology database information to predicting the possible toxicity of chemicals. The
goal is to combine available information on chemical structures and biotoxicity to predict toxicity of a chemical from its
structure. Routes of entry into the body, organs and systems affected, biological half life, modes of inactivation, and
dose-response relationships will be part of the prediction. In addition, the contractor’s system will provide ‘missing data’ flags.
As such, the system will indicate what information, if provided, would allow a more accurate prediction to be established. The
method can be used to predict effects of foreseeable industrial and environmental chemicals as well as unforeseen exposures
during military operations.
