Evaluation of Fungal Metabolic Compounds Released to the Air in a Restricted Environment

The metabolic action of selected fungi species on common components of the interior of Space Station Freedom (SSF) will be tested. When present, volatile organic chemicals will be collected on porous polymer adsorbent columns. Using thermal desorption, the volatile compounds will be passed onto a gas chromatographic column for analysis. The Space Station Freedom (SSF) modular complex will largely be individually self contained and the established air environment will not be easily adjusted. The development and maintenance of a safe working environment offers a considerable challenge. Present plans for use of SSF acknowledge periods of manned activities and alternate times when the station is unmanned. The obvious necessity for clean and safe air and water during periods of use have been pursued as fundamental systems to SSF success. Somewhat less obvious, although perhaps of no less importance to the success of long term cyclic usage, are those periods of inactivity. It is during these periods when spores from microorganisms may be afforded the best conditions to germinate and in the vegetative form react with the complex synthetic chemical polymers which compose the furnishings and hardware of SSF nodes. Biodegradation could constitute a real hygiene problem, if the organisms form and release volatile organic chemicals. Similar problems have been documented in closed and improperly ventilated buildings and work spaces. Many of the metabolic products of fungi and bacterial growth create a variety of health problems. Analytical chemical techniques will first be used to document the growth of Aspergillus, Penicillium, and Cladosporium fungal species on the potential substrates Nomex and Kevlar. Any volatile organics that are released will be measured using the spectrum of gas adsorption chromatography. The level of microbial contamination that is necessary to produce such volatile compounds and the relative amounts expected to accumulate will be estimated

Illinois Government Research no. 42 1976: Illinois and the United States: Some Economic Parallels

Illinois is situated both geographically and in production at the crosscurrents of the national economy. Virtually all U.S. industries have one or more firms with productive facilities in Illinois, resulting in a diverse state economy. To what extent, however, can Illinois be characterized as a "microcosm" ??? a representation in miniature or on a small scale ??? of the overall U.S. economy?published or submitted for publicatio

Causal Comparisons

Focusing on the multiple meanings of the statement A was a more important cause of C than was B, Professor Strassfeld considers the feasibility of comparative causation as a means of apportioning legal responsibility for harms. He concludse that by combining two different interpretations of more important cause --judgments of comparative counterfactual similarity and the Uniform Comparative Fault Act approach of comparative responsibility--we can effectively make causal comparisons and avoid the effort to compare such incommensurables as the defendant\u27s fault under a strict liability standard and the plaintiff\u27s failt for failure to exercise reasonable care

Amending the Treatment of Defense Production Enterprises Under the U.S. Exon-Florio Provision: A Move Toward Protectionism or Globalism

Discusses the Exon-Florio Provision of the Omnibus Trade & Competitiveness Act. It gives the President of the United States the power to prohibit or to prevent on a temporary basis a non-U.S. corporation from merging with or acquiring a U.S. corporation when the transaction could potentially impair U.S. national security. The Note examines U.S. legislation that regulates direct investment and argues that the U.S. Congress should amend Exon-Florio in order to focus and strengthen the Provision\u27s application to transactions involving U.S. defense production companies. Part I of this Note sets forth the existing procedural and administrative requirements of Exon-Florio and explains several modifications to the Provision that Congress has recently enacted. Part II outlines additional proposed modifications to Exon-Florio that have been presented before Congress and considers such proposals with respect to a recent case involving the Provision. Part III argues that Congress should amend Exon-Florio in order to focus and confine the Provision\u27s application to national defense. This Note concludes that such modifications would be justifiable because they would define national defense as a narrow exception to the traditional U.S. globalist trade policy and, consequently, benefit all those involved in international mergers, acquisitions and takeovers in the United States
