Dear Mary Kihanya,

        I'm the scheduled seminar speaker for May 7th.  I'm about to purchase
the airline tickets from Chicago, and I had a few questions.  Also,
I've included the form below, in case I forgot to send earlier.

I looked into flights into the San Francisco and Oakland, and could only find
ones at $400.  I checked into flying into LAX and driving up to San Francisco,
that ticket is only $313.  I was wondering if this itinerary is suitable
for reimbursement purposes, I would request no reimbursement for the drive from
LA to SF.

If you could also send a map and a few directions, I would appreciate it
very much.

Thank you,
Scott Burles

Title of talk                :
Deuterium measurements at high redshift and the cosmological baryon density

Abstract                     :
Observational constraints on the primordial deuterium-to-hydrogen
ratio (D/H) can test theories of the early universe and provide constraints
on models of big bang nucleosynthesis (BBN).  We measure deuterium
absorption in high-redshift, metal-poor QSO absorption systems and directly
infer the value of primordial D/H = $3.4 \pm 0.3 \times 10^{-5}$.  This is a
relatively low value, which supports homogeneous models of BBN with
$\eta = 5.1 \pm \, 0.3 \times 10^{-10}$ and
$\Omega_b \, h_{100}^2 = 0.019 \pm \, 0.001$.
