Hydrogen research 'facing a vacuum'

Challenges Facing Educational Research

Vacuum ultraviolet photodissociation of hydrogen bromide.

Photodissociation dynamics of HBr at a series of photolysis wavelengths in the range of 123.90-125.90 nm and at around 137.0 nm have been studied using the H atom Rydberg "tagging" time-of-flight technique. The branching fractions between the channels forming ground Br((2)P3/2) and spin-orbit excited Br((2)P1/2) atoms together with the angular distributions of the products corresponding to thes...

Facing up to paternalism in research ethics.

Bioethicists have failed to understand the pervasively paternalistic character of research ethics. Not only is the overall structure of research review and regulation paternalistic in some sense; even the way informed consent is sought may imply paternalism. Paternalism has limits, however. Getting clear on the paternalism of research ethics may mean some kinds of prohibited research should be ...

Presidential Address Challenges Facing Clinical Research

President-Elect Niederhuber, members of the Executive Council, my family and my friends in surgical oncology, and future presidents of this society. . . I begin by stating my humble but profound thanks for the honor of serving as the president of this society. I am honored to be following in the footsteps of people whom I admire and many of whom I count as dear friends. This society has contrib...

Hydrogen, Anti-hydrogen Beams Production in a Long Linear Vacuum Pipe

This paper presents the possible production of hydrogen and anti-hydrogen from p±and e∓beams merged in a long vacuum chamber (about 2500 m). In such a configuration with a beam kinetic energy for the p±around 100 KeV, the two key parameters are the density of the e∓beam and the temperature of the merged beams. The production rate is computed for several parameter sets and it is shown that it is...
