Recent papers discussing positron annihilation data from the galactic center have used several incompatible definitions of "the positronium fraction".
A CCD survey of a complete sample of 42 QS0 fields shows a significant excess of detected galaxies within 30 arcsec of the QS0, even for QS0 redshifts in the range 1 - 1.5.
I review the evidence for galaxy evolution, and describe recent observations of faint field galaxies.

Analyses of conventional microchannel and microgap cooling show that galinstan, a recently developed non-toxic liquid metal that melts at -19 C, may be more effective than water for high flux therm
For miniature interconnection applications, innovative material systems based on gallium alloys offer potentially attractive alternatives over commonly used bonding materials, such as solders and c
Gallium ion clusters Ga(+)(n) with n ranging up to 30 have been measured from liquid gallium ion sources using a time of flight spectrometric technique.
Droplets emitted from a gallium liquid metal ion source have been observed using an ion streak camera.
The observations of a damped intensity oscillation using reflection high-energy electron diffraction during the growth of GaAs by chemical beam epitaxy using triethylgallium and arsine are reported
Let q = p `` > 1 be a power of a prime p, and let k(q) be an overfield of GF(q).
