High- and low-pressure pneumotachometers measure respiration rates accurately in adverse environments
Respiration-rate transducers in the form of pneumotachometers measure respiration rates of pilots operating high performance research aircraft. In each low pressure or high pressure oxygen system a sensor is placed in series with the pilots oxygen supply line to detect gas flow accompanying respiration

Lp-norms of polynomials with positive real part
AbstractWe derive an estimate for Δn, 1 = sup{(2π)−1 ∝02π¦p(eit)¦dt: p(z) = 1 + a1z + · · · + anzn, Re(p(z)) > 0 for ¦z¦ < 1}. In particular it is shown that Δn, 1 ⩽ 1 + log(C1(n + 1) + 1), where C1 = 0.686981293…, It is also shown that 2π ⩽ lim infn → ∞ Δn, 1log n. Finally, upper bounds are found for the Lp-norms of polynomials with positive real part on the unit disk
Ultrasonic water column probe speeds up testing of welds
Ultrasonic device consisting of a coaxial rod and transducer enclosed in a cylindrical probe which is filled with deionized or distilled water speeds up the testing of welds. Rubber diaphragm is molded to produce the desired test beam angle
Study of contamination sensors. Volume I - Executive summary report
Design criteria for automatic remotely indicating fluid contamination sensors, monitors, counters, and recorders and for sampling equipment and technique
In vitro micropropagation of white dasheen (Colocassia esculenta)
Plant regeneration for efficient vegetative propagation in white dasheen has been developed. Meristem cultured on Murashige and Skoog medium supplemented with 6-Benzyladenine (BA) and Indole-3-aceticacid (IAA) gave the best explants establishment and development. This in vitro system provides for a uniform production system which is easily managed and yields high quality cornels for commercial production
