THE BOSTON AREA PHYSICS CALENDAR
          Week of January 21-January 27, 1996

The Boston Area Physics Calendar is published weekly during 
the academic year by the Department of Physics and Astronomy 
at Tufts University.  You may send your announcements by 
e-mail (bapc@tuhepa.phy.tufts.edu) or FAX:(617-627-3878).  
We cannot accept announcements by telephone.  Entries should 
reach us no later than 11:00am on the Monday preceding the week 
of the event. ENTRIES RECEIVED AFTER THE DEADLINE WILL NOT 
BE PUBLISHED.

``Physics of White Blood Cell Adhesion''
PROFESSOR ROBIJN BRUINSMA
University of California, Los Angeles 

Abstract:
 
The transport of white blood cells is of key importance for the
immune response system. The talk will discuss the hydrodynamic
mechanisms at work during the early stages of white blood cell
transport in post-capillary venules as well as the development
of weak adhesion during the second stage, where white blood cells
roll along the venules. 
 
Refreshments will be served in Room 333 at 3:30 p.m.

``Early Formation of Structure In the Universe''
DR. ABRAHAM LOEB
Center for Astrophysics 

Abstract:
 
Popular theoretical models of structure formation have been constructed so
as to survive observational tests at z<0.1 (galaxy surveys) and at
z=10^3 (microwave anisotropy experiments).  Thus, an efficient method for
selecting among current models is to study the universe at the intermediate
redshift interval 0.110 and discuss whether they
could have resulted in intergalactic stars. I will then consider the
subsequent formation and observational signatures of quasars, absorption
systems, and protogalaxies.  In particular, I will show that clustering of
Ly\alpha clouds lowers estimates of the UV background at high redshift,
that some QSOs must be gravitationally lensed by their damped Ly\alpha
absorption systems, and that the Tully-Fisher relation is probably not a
consequence of the formation history of protogalactic halos. Finally, I
will describe an empirical method to determine whether the observed
galactic magnetic fields are cosmological in origin. 
 
Tea will be served at 3:30 p.m.
