Does a LINAC that is used for cancer treatment using beta particles? http://www.varian.com/orad/prd055.html thanks

Hi, I have a general question about variational calculus (VC). I know the standard derivation of Euler-Lagrange equations and I´m able to use them. Nevertheless I think what I generally read cannot be the whole truth. Generally if f:M->R (M: arbitrary topological space, R: real numbers)...

And if so, how much heat is produced? Ok, so here's the problem. We are working with a generator salesman who is trying to sell a bunch of generators to a sewage treatment plant to capture the waste methane and burn it to make electricity. Great idea. The complication is that currently...

I'm looking for a book on Quantum Mechanics on an introductory level (concerning the physics), which is fairly advanced concerning the mathematics (i.e. some book that does not praise as a mathematical revolution that there actually is something called a dual space to some vector space). Do you...

"Treatment makes surfaces self-cleaning" I read this article, a few weeks ago http://www.engineerlive.com/european-design-engineer/instrumentationelectronics/17068/treatment-makes-surfaces-selfcleaning.thtml Do anyone know more about this? Can it actually be applied to metal? i.e...

I would need a pointer to a mainstream treatment of the general relativistic Doppler effect when source and receiver are accelerated wrt each other. Book/paper/wiki . No crank papers , please (i.e. no Apeiron and such). Thank you.

Can someone help me in finding information on the classical treatment of the potential in a carbon nanotube.

If the problem of retroviral infection is, like for example HIV, viral DNA segment integration in human DNA of immune system cells, why cannot be the same or similar method as used in treatment of patients with leukemia or blood cancers be applied here? What is preventing this? Couldn't infected...

Is there any treatment to cure those victim who got radiation overdose?

During the heat treatment of Aluminum alloys, two processes: Solution and Precipitation heat treatment were used. Should the hardness increase or decrease from the original alloy after solution heat treatment? My reference text says that the material should be "soft and ductile" after...

Infinity has been something that has been talked about a lot. A lot of Questions are being posted on this forum and elsewhere about the paradoxes involving infinity. I want to know if anybody knows some alternate treatment of infinity.

This last weekend I manged to get a pretty nasty scrape (area ~ 4cm diameter) on my shin. Now, 4 days later, it is getting better, (I missed some work due to this Sunday) but it still needs some help. I have been treating it with Bactine and Neosporin. What do you use or recommend for...

Hi I am in a competition where I have to use the deflection of a polystyrene beam to launch a projectile. Styrofoam is rather brittle but it is the only material we are allowed to use (it's cheap). I have a geometry all set but I was wondering if there is any possible way to treat the styrofoam...

hiiiiiiiiii I hope for helping me I have a senier project about "metal heat treatment furnace designe and manufacture" First: I want to calculate the heat rate that required to raise air heat from 15 to 40 c in a specific volume like room with volume 4*4*3. Second: I want to know about...

ok have a look at the diagram posted. When someone broke their femur (thigh bone) the muscles around the femur would compress tightly and thereby shorten the bone once it heals back. SO the apparatus described in the diagram is what they used to do to prevent the femur from growing back shorter...

I just finished reading Sakurai's treatment of feynman's path integral, and I'm left feeling really stupid. So the integral gives the propagator, which represents a transition amplitude. I'm left wondering what we use that for. Perhaps I'll understand when I start working some problems, or...

According to this paper http://www.sagewisdom.org/zhangetal.pdf Salvinorin A (active compound in Salvia Divinorum) lowers dopamine levels significantly right after injection. And according to "Dopamine hypothesis of schizophrenia" (...

1.Which of the following experimental techniques reduces the systematic error of the quantity being investigated? A.timing a large number of oscillations to find a period B.measuring the diameter of a wire repeatedly and calculating the average C.adjusting an ammeter to remove its zero...

So I apparently have lyme disease. The splotch I mentioned in the flu thread has been getting larger and darker (4 inches across by an inch and a half to 2 inches wide). Also my fever has been up to 103 a couple times in the past few days. And I have a couple more baby splotches on my arm and...

Why do we get hang nails and why do they form? Any way to prevent the annoying little things?

is tempering the correct heat treatment for automotive panel? coz I've seen different version of heat treatment.. some books said tempering, website said (key to steel) said case processing/ annealing (seldom quenching and tempering), actually which one is correct? actually i'd prefer...

Hi, Recently I discovered 2 acnes on my face and neck. My mom told me is acne. Anyone know any good acne treatment!? -Tom

Just seen an interesting documentary about the breakthrough in Cancer treatments. The programme gives a brief discription on cell division and how doctors think the way forward for treatment is changing due to the Understanding of Genetic (genome) discovery. Anyway I was fascinated by the film...

http://www.foxnews.com/story/0,2933,104730,00.html The video is more informative than the article.

In Neurotherapy individuals are trained through the use of computerized biofeedback equipment to change their brainwave activity. Do you feel it is less intrusive to use this therapy on children rather than the drugs they now administer ? It is scary these days that a school teacher can...
