Anodized aluminum on LDEF: A current status of measurements on chromic acid anodized aluminum
Chromic acid anodize was used as the exterior coating for aluminum surfaces on LDEF to provide passive thermal control. Chromic acid anodized aluminum was also used as test specimens in thermal control coatings experiments. The following is a compilation and analysis of the data obtained thus far
Selected results for LDEF thermal control coatings
Several different thermal control coatings were analyzed as part of the Long Duration Exposure Facility (LDEF) Materials Special Investigation Group activity and as part of the Space Environment Effects on Spacecraft Materials Experiment M0003. A brief discussion of the results obtained for these materials is presented
Z306 molecular contamination ad hoc committee results
LDEF external surfaces which did not receive significant amounts of atomic oxygen were observed to be coated with a brown contamination, apparently the result of a condensed organic residue darkened due to UV radiation exposure. During the initial Materials Special Investigation Group (MSIG) Meeting after LDEF deintegration, held in Seattle - July 1990, this organic contamination was the subject of much discussion. The amount of contamination was thought to be significant and its source was immediately believed to be the Z306 black thermal control coating used to coat the entire inner surface of LDEF. Due to the size of the structure, it was not feasible to bake-out the coating. However, initial data on the contamination film was confusing in that significant amounts of silicon was observed by several different researchers. Silicon (from silicone) was not expected to be a potential outgassing product of the Z306 polyurethane coating. To investigate the connection between external contamination and the interior paint, a MSIG ad hoc committee was formed

Health Effects & Wine: The FDA Should Regulate the Health Effects on Wine Labels
In 1976, the District Court of the Western District of Kentucky, in Brown-Forman Distillers Corp. v. Matthews, found that alcoholic beverages were exempt from the Food & Drug Administration labeling requirements. Since then the Bureau of Alcohol, Tobacco, and Firearms has had exclusive jurisdiction over the labeling of alcoholic beverages. As a result of the recent findings on the health effects of alcoholic beverages, in particular wine, it is necessary to revisit that 1976 decision. The FDA currently allows health claims to appear on the labels of food as long as there is significant scientific agreement on the evidence to support the claim. These standards establish a workable rule to allow health claims to appear on food and drink. These guidelines should be expanded to cover wine labels
Speaches Seeming Fitt : Rhetoric and Courtesy in The Faerie Queene
The practice of courtesy was of the utmost importance in Renaissance England; courtesy was tied to social standing, virtue, and civility. Spenser joins in a rich tradition of courtesy literature by including the Book of Courtesy in The Faerie Queene. His presentation of courtesy goes far beyond the limited discussion of the concept by his predecessors and peers; instead of limiting his depiction of courtesy to “courteous” behavior, Spenser includes every aspect of courtesy, including courteous and completely discourteous behavior and effective and ineffective expressions of courtliness.
Spenser’s courtesy involves layers of complexity that exist in various social spheres throughout The Faerie Queene. The wide-ranging nature of the poem enables Spenser to explore virtue in varied physical and allegorical contexts, thus allowing the reader to view courtesy in multiple contexts.
Spenser’s conception of courtesy may be viewed in four discreet types of characters: moral courtiers, unrhetorical but inwardly courteous individuals, artful courtiers, and discourteous individuals. A close analysis of each type of courteous or discourteous character leads to a more nuanced and fuller understanding of Spenser’s portrayal of courtesy. This study reaches outside the Legend of Courtesy and views the virtue of courtesy throughout the entirety of The Faerie Queene. Focal characters include, but are not limited to, Arthur, Britomart, Florimell, Redcrosse, Salvage Man, Satyrs, the Salvage Nation and Brigands, Duessa, Archimago, and Malecasta. An analysis of each of these widely differing characters contributes to the reader’s understanding of courtesy and the relationship between courtesy and rhetoric in Spenser’s work
