I'm glad to see Dominici doing something about the regulations.
It is estimated that Albuquerque (pop 500K) may have to pay
$250 million to comply. While that is an immense burden on
Albuquerque (for highly questionable gain), the proportional
burden pales in comparison to that of small, rural communities.
If required to implement the existing regulations, many
small communities would literally go bankrupt.

Like the irrational fear of radioactivity displayed by several
sci.med posters recently, fear of trace contamination with
manmade pesticides provokes irrational, disproportionately
severe responses. Personally, I would like to see some of
this energy directed toward more concrete threats, like that
of self-poisoning with unnecessary "health" nostrums and
megadose vitamins. The example of L-tryptophan, the cause
of EMS in thousands, leaps to mind.

Well, there are actually two well-known photoresist
modeling software packages. One is SAMPLE, a creation
of Prof. Andy Neureuther et al. (Dept. EE & CE, UC Berkeley),
and the second, gaining in popularity because of numerous
options included, such as contrast enhancement etc, by
Chris Mack & Co. (Finle Technologies, Plano, TX 75026)
The second one looks very glitzy. Forgot the prices, thou :-(.

Hope it helps.

Gentlemen:

We have been asked to put together (pro bono) a process that demonstrates
gas-liquid contacting. The following equipment has been inherited:

     Chem-Pro glass column, 4 feet with top/bottom disengaging sections
     6 perforated plates, 316SS
     6 inch diameter column
     Blower and liquid circulation pump

We can design/supply any and all instrumentation.

Limitations:  This demonstration is to be carried out indoors, which means
a "safe" gas and liquid. Air is obviously the preferred gas. Virtually any
safe "room temperature" liquid will do.

What we would like is a physical/chemical process that manifests itself to
the eye through the glass column. For example, a change in liquid color
up and down the column would be nice.

We have thought about adjusting liquid pH with a reactant in the gas phase,
and following this with a indicator in the water phase, but don't like the
idea of introducing "noxious" gases into the air going up the column, as
some of it is sure to escape into the room.

Any suggestions? Reply by email, posting, or whatever. If you post, please
let us know, as we don't always get everything that is posted to this group.

But if these "foreigners" are this skilled, doesn't that mean that U.S. 
students have the same chance for the same skills?  Let's examine.

If the foreign engineers are getting degrees at foreign universities, perhaps
we should blame American higher education and not big business.  American 
colleges have all thest all the amenities of colleges worldwide, so the grads.
they produce should be lacking none of the skills foreign engineers have.  
Thus there may be a problem with American learning institutions which needs
to be discussed.

On the other hand, if foreign engineers are being trained at U.S. colleges,
then the glaring question is How are they learning more than their U.S.
counterparts?  They are reading the same texts, sitting in the same classes,
and listening to the same profs as the "home team".  This seems to point to
a problem with the work ethic and motivation of U.S. students.

I am a U.S. college student.  I was born in this country, and currently co-op
for a U.S Utility.  I've seen good students and bad ones from both the U.S. and
abroad.  I'm not trying to condone business practices or defend foreign students
from U.S. criticism.  All I'm trying to do is offer another p.o.v.  Perhaps
before we need to check on our players before trying to say the rules are 
unfair.

Interesting Thread.  I'm wating for the flames to start rolling in.

	Another reason might be that employers have a different perception.
If they viewed foreign scientists as more cost effective (similar talent
level, but demanding less pay) then it is very hard to compete.  You simply
have to be the best in the world at what you do, just to have good job prospects.
If we consider people who leave their homelands for political reasons, or to
escape severe economic hardship, then the local talent is likely to be much
more expensive.  It would be hard to verify/deny this as the argument that
employers won't admit holding such unpopular views is valid.

Here in the University of Tulsa, Oklahoma, we have several courses 
dealling with multiphase flow. In particular, we have
'two-phase flow modelling,' covering steady state flow aspect and
'two-phase flow simulation,' covering transient flow situation.

My MS work is about flow pattern and pressure drop prediction
for gas-liquid two-phase flow in pipelines. Now, I am working on
my PhD and part of the work involves simulation of two-phase
transient flow.

I am very much interested in your course notes, what you did in
your PhD work and the text book you are working on.
I'll be glad if we can exchange information on this fast growing subject.

G'day all,

I was wondering if there was a public domain program for doing
dynamic simulations of simple coupled syatems. The type of 
program I am thinking about would be kind of like 'ACSL' where
you write Fortran type statements describing the system and the
program writes another program that includes the specific library
calls that are needed to do the simulation.

Are you sure you mean 1969?  In 1969 Granatelli ran cars with turbocharged
Ford motors, Mario Andretti winning that race!  Also turbines weren't banned
until the 1971 race, but the downsizing of the allowable inlet area from
23 sq. in. (1967) to 15.999 sq. in. (1968) to 11.999 sq. in. (1969) really
did them in.

In 1967, Parnelli Jones was leading until 4 laps from the end of the race
when a bearing gave out.  In 1968, both Joe Leonard and Art Pollard fell out
of the race with 9 laps and 12 laps to go respectively....both with broken
fuel shafts!

I wonder who really did away with the turbines........

        A few years ago, someone in LA put a helicopter turbine in a
car.  They used the backup turbine from Gratenelli's 1969 Indy car.
(which nearly won Indy that year, but after being many laps out in front
for most of the race, had a transmission failure near the end.  Turbines
were then banned at Indy.)  

        The LA people used a Corvette as the platform, needing a long
engine compartment.  The turbine was rated at 1500hp continuous, I think.
One of the car mags wrote this up, along with dragstrip performance
figures.  

        Basic problem with turbines in a car is that you don't need much 
power at cruise (maybe 7-10hp in a modern car) and turbines are inefficient
at very low power settings.  Turbines also have far more expensive 
construction and metallurgy than reciprocating auto engines (which actually
cost only about $100 to make).  Chyrsler built some demo turbine cars
in the 1960s, but never went to production.  Ford built some demo trucks
in the 1970s, but never went to production.  The M1 tank is turbine
powered, and there have been a few other experiments, mostly for large
vehicles.

        Greyhound, in the 1970s, tried hard to get someone to make them
turbine-powered buses, hoping to improve the quality of bus travel and
compete with the airlines.  They couldn't find anybody to make them.
So they reduced the quality of bus travel instead.
