    Ecological effects and environmental fate of solid rocket exhaust

    Specific target processes were classified as to the chemical, chemical-physical, and biological reactions and toxic effects of solid rocket emissions within selected ecosystems at Kennedy Space Center. Exposure of Citris seedlings, English peas, and bush beans to SRM exhaust under laboratory conditions demonstrated reduced growth rates, but at very high concentrations. Field studies of natural plant populations in three diverse ecosystems failed to reveal any structural damage at the concentration levels tested. Background information on elemental composition of selected woody plants from two terrestrial ecosystems is reported. LD sub 50 for a native mouse (peromysous gossypinus) exposed to SRM exhaust was determined to be 50 ppm/g body weight. Results strongly indicate that other components of the SRM exhaust act synergically to enhance the toxic effects of HCl gas when inhaled. A brief summary is given regarding the work on SRM exhaust and its possible impact on hatchability of incubating bird eggs

    The Government Contractor Defense

    Litigation involving defective products has increasingly become a pre-trial battle to overcome a series of technical defenses that have become a stock part of the manufacturer\u27s defense. Defendants invariably raise the government contractor defense where the defective product resulted from some governmental involvement in the manufacturing process, no matter how peripheral or superfluous was the government\u27s involvement in that process. The defense by its nature only applies to design defect cases. A defect in the manufacturing process is not protected by the defense

    A Semantic Analysis of Over- and Underachievers

    An investigation was conducted to determine the relationship between contrasting levels of reading achievement and three psychodynamic factors, identification with parents, relationship with peers, and the value of reading and good grades. Selection of the Ss was made by statistical methods utilizing data obtained from school records. The device for testing the hypotheses was a form of the semantic differential administered to the Ss in their homes. The findings indicate no relationship between levels of reading achievement and parental identification, relationship with peers, or reading and good grades except in one instance in which overachieving males valued reading significantly different than underachieving males. Further research regarding identification, its nature, its measurement, and its relation to reading achievement is recommended

    Improving Our Ability to Estimate Vital Rates of Endangered Fishes on the San Juan River Using Novel Applications of PIT-Tag Technology

    Estimating demographic parameters, such as survival and abundance, with accuracy and precision is vital for detecting trends in populations and assessing the effectiveness of management actions. In most cases, a lack of capture data make estimating parameters very challenging. The use of new technologies to increase the amount of remotely collected data is increasing, but brings new limitations and analytical issues to be resolved. One of those new technologies is the use of a mobile floating PIT-tag antenna to detect PIT-tagged fish. The issue that arises with this technology is determination of the status of detected tags (i.e., live fish or ghost tag; a tag left in the environment when a fish dies or sheds its tag). The objective of this study was develop a method to determine the status of tags detected with a mobile floating antenna. I determined the movement dynamics of known ghost PIT-tags and contrasted them with known live fish. I used a random forest analysis to develop a classification model for the two different states. I found ghost tags exhibited movement that is to be expected based on sediment transport analysis and that the distance and direction moved, and response to changes in flow were the most important variables for correctly determining tag status. This study provides a useful framework for developing models for other systems, even though the relative importance of specific predictor variables will most likely vary with location and species of interest

    You\u27ve Got It Coming -- Winning Discovery through Effective Motions Practice

    Get PDF
    An effective discovery motion begins with the underlying discovery document and a thoughtful plan for discovery. This article will begin with a brief overview of the more important substantive legal points relevant to discovery. The materials will then address some of the more recurrent problems encountered by counsel during the course of discovery. Finally, the discussion will examine the timing, form and content of discovery motions

    Through the Looking Glass Darkly: Cleveland v. Piper Aircraft and Second Collision Liability

    Get PDF
    The holding in Clevland v. Piper Aircraft Corpororation is in direct conflict with the analysis for the tort of crashworthiness and operates to undermine the fundamental social policies which formed the basis for the tort of crashworthiness. A thorough understanding of the Tenth Circuit\u27s opinion, which is not binding on New Mexico state courts, and the reasons why the court misconstrued New Mexico law is essential for the successful prosecution of a crashworthiness cas
