NiCd *cells* may be stored in any charge state, although there may be some
reason not to store them for extended periods in a deeply discharged state.

Storing NiCd batteries in a fully-discharged state can also be a Bad Idea,
as self-discharge will eventually cause one or more of the cells to get
in a bad way; i.e., the cells do not all discharge at the same rate, and so
it's conceivable (esp. for higher-voltgae batteries) that one or more could
wind up seeing a reverse charge.  Still, this would take an extended
period of storage before any real problems are likely, assuming that the
battery wasn't nearly  full-discharged to begin with.

The same as it did when it was part of the rotor - one hell of a lot.
Plenty to blow through any of the simplistic housing proposed in this
discussion.  Remember, kinetic energy is 0.5 M V^2.  The M may not be a
lot, but the V is beyond anything in your experience (these discussions
of speeding trucks and bullets are just nonsense in comparison).  And it's
the V that's squared there.  The impact of the fiber with the housing
is well beyond any elastic limits - it generates a shock wave in the housing,
and melts or even vaporizes the housing at the point of impact.

Ceramic.  Big deal.  A meteor melts the rocks it impacts and it is not
moving as fast as the flywheel rotor - and ceramic is nothing more than
glassy rock.   It will melt.

> I think I'll look these up, does anyone have a reference?

Look what up?  The melting temperatures for ceramics?  Lots of references,
but you don't understand the physics here.  The particles have so much
energy that they will melt any solid in existance.  This has more to
do with the molecular behavior of the material - the impact velocity is
so high that the atoms are forced well beyond any sound speeds.  They
then form a shockwave, completely disordeing the material, leaving it
in a fluid state and creating a great deal of heat.  Just check some
sound velocities and compare that to the velocity of the particles from the
rotor.  That starts to give you an idea of what kind of regime we're in.

Does this mean that subjects who have schizophrenia as a consequence
(or so it is supposed) of cortical atrophy do not exhibit positive
symptoms?  Or does it mean that, while exhibiting positive symptoms,
the degree of this is not correlated with the degree of cortical
atrophy?  Is a diagnosis of schizophrenia made on the basis of *only*
negative symptoms?  Do all schizophrenics (clinically diagnosed)
exhibit cortical atrophy?

If there are "phases" of the illness, are there corresponding phases
of cortical atrophy?  If brain tissue loss is causally related to
the symptoms of the disease, and the loss is irreversible, what
accounts for the recoveries?  Is there evidence of compensation in
other areas of the brain?

I get confused when I hear people talk about vitamin C and the effect
it has on their colds.  First of all, my colds are very individualistic.
Sometimes I have a sore throat, sometimes they last for 3 days, sometimes
they last for 10 days, sometimes my head aches, sometimes my skin hurts.
I suppose it depends on the virus I'm inflicted with.  Not only that, but
I usually only have 1, sometimes 2 colds a year.

Given the relative rarity of colds, and the different symptoms and
severity, how can you decide that vitamin C is helping or you just
have a mild cold?

Summary: Why aren't Western Europeans so often morbidly obese?


Why aren't Western Europeans so often morbidly obese?

I recognize that obesity is multifactorial, and that on the same diet
some people wil become fat while others will remain thin. Also, there
are some well-described--but rare--medical conditions that will cause
people to become very obese on a small caloric intake.

However, one certainly has the impression that the incidence of morbid
obesity is much higher in this country than in most, if not all, other
wealthy western countries, from whose inhabitants  >80% of Americans
derived their genes. (Obviously, it is much much higher than in Africa
and Asia where most of the remainder originated, but perhaps for other
reasons).  So one is compelled to ask what other factors lead to the
incidence of morbid obesity in this country. In the absence of a more
compelling argument, the most likely explanation is lifestyle (diet
and exercise). If this is the explanation, how is that consistent with
the recent evidence suggesting a biological prediliction to obesity?

There are many patients who have damage to the tracts linking the
frontal lobes to the limbic system who have such "emotional
incontinence".  They usually have similar spells of uncontrollable
crying, often in conjunction with the laughter.

There are also gelastic seizures, a form of epilepsy that
is characterized by uncontrolled laughter.

Because it's ineffective; it only works against strains of influenza A.
On the other hand, if someone comes down with flu-like symptoms in a
household, it's a good bet that it's the flu.

Nervousness, difficulty concentrating, insomnia or excitement; all some-

When I've taken it for the flu, I've had no side effects at all.

I just heard a news story about a man in Quincy, Illinois.
Apparently he showed up in an ER complaining of chest pains
shortly after a robber had held a gun to his head.  They
checked him out, found nothing wrong with his heart, and
suggested he was probably suffering from "post-traumatic
stress syndrome" and that he should stay overnight.

They also reported his stay to the state, which pulled
his gun license.  Apparently, Illinois law will not allow
anyone to own a gun who has ever been treated in a hospital
for any mental disorder.

At no time during any of this was there any suggestion that
he might be a danger to himself or others.  He has filed an

Hi David. Have you considered that whatever the original process causing
the panic attacks was hasn't been resolved yet?  I hear lots of folx have
problems getting off Xanax.  In most cases I see these folx reverting to
their old behaviours that caused them to be on the stuff in the first
place. Was the Rx given by Psychiatrist or a non-specialist MD? Have you
been in some kind of theraputic regimen that seemed to be working for
you?  If your problem is performance anxiety (the public speaking kind,
not the sex kind), then it's unlikely you were prescribed _enough_ Xanax
to give you such a withdrawal problem. 

Not a doctor. But a fully-recovered Panic Disorder sufferer who used
Xanax too.
