It is generally not recommended to mix medications directly into the EN formula because of concerns that physical incompatibilities between the medications and the formula might lead to tube occlusion. There is some evidence that polymeric formulas are more likely to demonstrate physical incompatibility with medications compared with monomeric formulas, although most of the work in this area has used casein or caseinate-based formulas, and other proteins may act differently.38 The limited data currently available would indicate that acidic syrups and elixirs may be the worst for causing physical incompatibility when admixed with EN formulas. It has been postulated that this incompatibility is due to changes in the protein structure after exposure to acid or alcohol.38... 

There is little available or published evidence to indicate that the antibiotic and sulfonamide residue profiles of similar products not used for export would be different. Until data can be found that indicate otherwise, the only assumption consistent with data is that residue levels and incidences are similar throughout the parts of the world where reasonable regulatory practices exist. However, for areas where regulatory monitoring is not considered important there is no system for estimating extent of residues. It may be prudent to make a worst-case situation assumption for these areas, namely that there would be a high frequency residues in products of animal origin. 

Let s revisit the cleaning of the tank and obtain samples from many different locations and choose sampling locations that fairly represent the entire equipment rather than just the single worst-case location. Let s assume that we still have the same total limit of 100 mg and that we still have the same tank having a total surface area of 100,000 sq. in. We still have the 0.1-mg swab for the manway gasket, but we now will take additional representative samples from each of several locations. Again we will swab areas of 2 in. x 2 in., just as we did previously. The data obtained are presented in Table 7. 

This area, pathway simulation, requires extensive literature validation. The kinetic constants for every reaction in the pathway (usually in the hundreds) and the concentrations of every protein (usually less than one hundred) in the scheme must be informed from the literature. It has been our experience that this kind of detailed information is not available from abstracts. In the past, individuals read papers for the required information to develop these models. Because no one can read literature in its entirety, the readers would stop either when they found the first instance of the necessary fact or after reaching their attention/frustration limit. The manual approach at best does not explore the complete range of values available from different sources and at worst leaves many of the values blank. 

It would be safe to suggest that in the worst case scenario (low density of boards, such as 1.06-1.08 g/cm ) and direct sunlight most part of the day, GeoDeck boards without added antioxidants begin crumbling after about 6 months in the Phoenix, AZ, area. The OIT of those boards at 190°C typically are in the range of 0.2-0.3 min. Thus, for those boards the difference between the OIT and their average lifetime ...
