    Notes: Summary In an attempt to assess the role of histamine H3 receptors in the control of gastric acid secretion, the effects of the selective histamine H3 receptor agonist, (R)α-methylhistamine and antagonist, thioperamide were evaluated in the conscious gastric fistula cat under basal conditions and against different stimuli. (R)α-methylhistamine (0.05–0.2 μmol/kg/h) was ineffective against spontaneous and dimaprit-induced acid secretion; it also did not reduce significantly pentagastr-ininduced acid output, but caused a dose-dependent (0.05–0.1 μmol/kg/h) and significant inhibition of the acid response to 2-deoxy-d-glucose. Thioperamide (0.02–0.04 μmol/kg/h) did not modify spontaneous acid secretion, whereas it evoked a significant enhancement of the acid response to submaximal doses (50 mg/kg i. v.) of 2-deoxy-d-glucose. Thioperamide completely reversed the inhibitory effect of (R)α-methylhistamine against 2-deoxy-d-glucose-induced secretion, while leaving unaffected the inhibition induced by somatostatin. These data suggest that histamine H3 receptors may be involved in the control of acid secretion stimulated by indirectly acting secretagogues.

    Synthesis of (Hg,X)Ba2Ca2Cu3Ox Superconductors (1998)
    Springer

    Notes: Abstract Synthesis and processing parameters for (Hg1−xBix)Ba2Ca2Cu3.1Oy were optimized for growth at temperatures suitable for growth on Ag and Au substrates (〈850° C). Use of Bi2CuO4 as a Bi source combined with variations of BaCaCuO precursor phase assemblages allowed the formation of some liquid phase during the reaction and resulted in dense (Hg1−xBix)Ba2Ca2Cu3.1Oy samples with aligned colonies of grains. Magnetization measurements in fields up to 30 T indicated good intergrain coupling within the large grain colonies. The results of the Bi doped samples are compared with those of previously reported Re doped samples.

    Analytical model reduction of large scale linear dynamic systems (1977)

    Notes: A class of dynamic model approximation techniques based on a frequency domain Taylor series expansion is presented. These methods yield low-order models and are analytical rather than computational in nature; that is, one can retain important parameters (which may be time varying) from the original model in functional form in the low-order model. This feature is very attractive for on-line updating of the simplified model and subsequent control of the process. An example for a tenth-order original model has shown that the analytical low-order models provide excellent approximations to the step response of the original system.

    Notes: A new tracer technique is reported for the determination of liquid-solid contacting efficiency and liquid holdup in trickle beds packed with small alumina particles. Holdup was a function of liquid mass velocity for both porous and nonporous packing. Contacting efficiency remained uniform at a level of 65%.
