Abstract: A method for rudder roll stabilization having two-feedback-path nonlinear dynamic compensation (NDC) is described. The high-order, Nyquist-stable control system having NDC hereof is absolutely stable and will provide a 20%-40% improvement in performance over existing roll reduction designs when lower performance steering mechanisms are employed, and is superior to linear controllers. That is, the present invention will be effective rudder roll stabilization in commercial vessels having slower rudders as well as in vessels having steering machines representing the best performance currently available, such as military systems. Since no ship hardware modifications are required, the present roll control technology will be able to be economically implemented.
Abstract: A system for determining parameters and compatibility of a substance such as an asphalt or other petroleum substance uses titration to highly accurately determine one or more flocculation occurrences and is especially applicable to the determination or use of Heithaus parameters and optimal mixing of various asphalt stocks. In a preferred embodiment, automated titration in an oxygen gas exclusive system and further using spectrophotometric analysis (2-8) of solution turbidity is presented. A reversible titration technique enabling in-situ titration measurement of various solution concentrations is also presented.

Abstract: The present invention provides methods and compositions for detecting, identifying and measuring the abundance of chemical nerve agents. Methods and compositions of the present invention are capable of providing selective detection of phosphorous based nerve agents, such as nerve agents that are esters of methyl phosphonic acid derivatives incorporating a moderately good leaving group at the phosphorus. Selectivity in the present invention is provided by a sensor composition having an alpha (?) effect nucleophile group that undergoes specific nucleophilic substitution and rearrangement reactions with phosphorus based nerve agents having a tetrahederal phosphorous bound to oxygen. The present invention includes embodiments employing a sensor composition further comprising a reporter group covalently linked to the alpha effect nucleophile group allowing rapid optical readout of nerve agent detection events, including direct visual readout and optical readout via spectroscopic analysis.

Abstract: The cDNA that encodes a glycoprotein receptor from the tobacco hornworm which binds a Bacillus thuringiensis toxin has been obtained and sequenced. The availability of this cDNA permits the retrieval of DNAs encoding homologous receptors in other insects and organisms as well as the design of assays for the cytotoxicity and binding affinity of potential pesticides and the development of methods to manipulate natural and/or introduced homologous receptors and, thus, to destroy target cells, tissues and/or organisms.

Abstract: A method is disclosed for analyzing keratinized tissue, particularly fingernails, of a subject to diagnose osteoporosis and bone fracture risk. A Raman spectrum of a sample of keratinized tissue is generated. Broad spectral background features of the spectrum are removed, preferably by using Fourier transform analysis. Peak heights of Raman features of interest, particularly the S—S bond of cystine, are measured. These peak height measurements are normalized using reference peak heights of Raman features that are invariant between normal and osteoporotic subjects, such as the CH2 bending peak.
