Don't we understand how many prominent Soviet scientists are desperate for cash in the aftermath of the collapse of the former Soviet Union and the skewed government payroll that paid them?

And is it sound thinking to assume that there aren't any Soviet nuclear scientists who still believe in the communist doctrine and despise the capitalist Americans?

I think you can see where I'm going withh this.

There was no incentive for the former Soviet Union to spend the intensely high amount of capital required to secure and guard all of the fissile material existing in so many different places.

The trillions of dollars we are currently spending in our war against terrorism are dollars we should have spent to assure this fissile material was 100% accounted for and secured.

The previous Ford, Carter, Reagan, Bush, and Clinton administrations were completely flat-footed on this all-important issue.

I have a background in IT and Business. I want to learn engineering terminologies (e.g. material take-offs from drawings plan profile isometric). I want a certification course so I can include it in my resume. A certification similar to PMP(Program Management Professional) certification from PMI(Project Management Institute).

If I need to spread my 4 point weight across a given area. How would I "Caluculate" and select the correct plate thickness, ie 3/8in, 1/2in, etc. Let's assume 5000LBS -
Dimensions - 5ft (60in) x 5ft(60in) x 4ft(48in)

See there a website or table in a book

I can't wait till someone builds one! I know it'll happen sooner or later and I know right now with the level of current american design, engineering and technology it can be done without great or expensive difficulty

I have a basic understanding of how a turbo or supercharger works--increasing the amount of air that can enter the engine at any given time, thereby allowing more fuel to be burned. Since there's more air forced into the cylinder, higher-test gas must be used to avoid knocking due to the increased pressure within the cylinder.

But what if you didn't increase the volume of air entering the chamber, but increased the amount of oxygen in the air charge (by introducing pure O2 into the intake)? The atmospheric pressure would essentially be the same, but the added oxygen would allow more fuel to be burned at once than with non-enriched air.

Would you still need to run high-test gas, or could you run good ol' 87 regular? The cylinder pressure shouldn't change, so the temp during compression should be similar. But would the added oxygen make the fuel mixture more prone to early detonation, therefore requiring high-test?

I am looking at a circuit and trying to figure out what some of the things on it are. There is one component that looks like a cylinder sliced down the middle with two wires coming off one end soldered to the board. the cross-section of the component is a half-circle. It is black in color. Is this a capacitor?

A landscaper does a lot of work such as planting plants, fixing pipe lines, fixing sprinklers, install concrete patios & walkways, build fencing & gates, etc. Would he be a civil engineer since he does the planning, designs, constructing, and maintenance?
