    Excess noise induced in metal resistors as a result of dynamic processes (1992)

    Notes: Excess noise is induced in thin gold films when the film is put in contact with an electrolytic solution. The magnitude of the noise changes as a function of the concentration of the ions in solution and follows a Temkin adsorption isotherm. Excess noise is also observed in a platinum wire exposed to water undergoing solidification. All measurements are made in the absence of an external applied bias. This implies that a dynamic process moving towards or at equilibrium can induce excess noise in a metal resistor.

    Interrupt-driven digital controller for a magnetic suspension system (1989)

    Notes: The hardware interrupt structure of an MS-DOSTM -based personal computer was used to enable real-time, keyboard manipulation of the control parameters of a stable, vertical magnetic suspension without halting its operation. The positions of objects suspended with this system were measured to be stable to within ±15 μm of a reference position. Stable suspensions were achieved at sampling rates as low as 45 Hz, although the system was typically operated at sampling rates of 1.0–2.0 kHz. The dynamics of the suspension were explored for several different values of proportional, integral, and derivative gains, and the system's transient response and steady-state behavior were characterized. We present here the data resulting from those studies, as well as measurements of the suspension's drift, empirically determined values of its second-order transfer function parameters, a discussion of the suspension's foreground/background capabilities, a description of its algorithm, and details of its electromechanical construction.

    Magnetically suspended centrifuge for studies of nonlinear phenomena in stratified fluids: Developmental aspects (1989)

    Notes: Design studies of a novel magnetically suspended centrifuge suggest that such a device would be useful for investigating the nonlinear dynamics of interfacial waves in a rotating two-phase liquid. In its final form, the apparatus would use magnetic bearings, a directly-driven rotor, precision temperature control, and vibration isolation. The mechanical noise in the magnetic suspension coil of a preliminary apparatus was measured to be 3-μm rms in a 5-kHz bandwidth. However, these vibrations were attenuated by an active differentiator to the point where there was no observable oscillation in a 183-gram suspended test mass.

    The extracellular matrix of Gadus morhua muscle contains types III, V, VI and IV collagens in addition to type I (2005)

    Notes: Confocal microscopy and immuno-histochemistry were used to examine collagens in the extracellular matrix of cod Gadus morhua swimming muscle. In addition to the well known presence of type I fibrous collagen, types III and VI were also found in the myocommata and the endomysium. The beaded collagen, type VI, was found in the endomysium and the network forming collagen, type IV, was found in the basement membrane. This is the first report of type V collagen in cod muscle and of types II, IV and VI in the muscle of a teleost.

    COUNTERCURRENT EXCHANGE OF EIIGHLY DIFFUSIBLE TRACERS IN SKELETAL MUSCLE: ITS ABSENCE IN THE LUNG (1977)
    Oxford, UK : Blackwell Publishing Ltd
    Clinical and experimental pharmacology and physiology 4 (1977), S. 0

    Notes: 1. Multi-exponential rates of desaturation of highly diffusible tracers were observed in vascular washout of skeletal muscle. This led to the hypothesis of counter-current exchange of such solutes between pre- and postcapillary vessels which are closely apposed in skeletal muscle. By contrast, in the lung pre- and postcapillary vessels are separated by alveolar tissue.2. The ‘indicator diffusion’ method was used in studies on both organs. A vascular reference tracer and a highly diffusible tracer (125I-iodoantipyrine, 3HOH, 14CO2) were rapidly injected intra-arterially. Venous samples were collected to determine tracer concentrations. From the venous concentrations of the reference and diffusible tracers extraction of the diffusible tracer into the tissue could be determined.3. In the lung the diffusible tracers conformed to theoretical predictions. High extractions of diffusible tracers into lung tissue occurred in early venous samples. The values declined in subsequent samples as a result of significant tissue concentrations of the diffusible tracers.4. At low flows in skeletal muscle precession frequently occurred of the diffusible tracer ahead of the reference tracer. Extractions of diffusible tracers were low in early samples and subsequently increased to a maximum. At high flows these effects were considerably less. These features are characteristic of countercurrent exchange.5. In vivo in resting muscle, pre- to postcapillary shunting of O2 and of CO2 in the reverse direction would become cyclical. The hypoxaemia and hypercarbia would dilate precapillary vessels leading to increased flow thus reducing diffusional shunting of the respiratory gases. The resultant rise in oxygen tension would allow vascular constriction reducing flow and increasing shunting. This is consistent with vasomotion. In exercising muscle the marked increase in flow would minimize this shunting.

    The evolution to stool DNA testing for colorectal cancer (2004)

    Notes: Despite a variety of screening strategies and recent trends showing death rate stabilization, colorectal cancer still remains the second leading cause of overall cancer death. Current screening tools suffer from performance limitations, low patient acceptability, and marginal reliable access within the health care system. Noninvasive strategies present the lowest risk with the highest potential for patient satisfaction. However, serious implementation barriers exist requiring consistent programmatic screening, strict patient adherence, and poor sensitivity for adenomas. Colonoscopy remains an invasive screening test with the best sensitivity and specificity, but faces large financial costs, manpower requirements, patient access and adherence. Development of advanced molecular techniques identifying altered DNA markers in exfoliated colonocytes signify early or precancerous growth. Stool-based DNA testing provides an entirely noninvasive population-based screening strategy which patients can perform easier than faecal occult blood testing (FOBT). Large-scale prospective randomized control trials currently pending should help characterize accurate test performance, screening intervals, cost-effectiveness, direct comparison to FOBT and analysis of patient adherence. As tumour development pathways and potential target genes are further elucidated, refinements in multi-assay stool-based DNA testing portend enhanced test characteristics to detect and treat this genetically heterogeneous disease.
