ICF's are stronger, more thermal friendly, quicker to build and have better sound deadening properties. Why haven't
more builders caught onto this?

my 10 year old has trouble calming down to go to sleep. a friend of mine told me that it would be okay to give her over the counter melatonin to help her calm down. she weighs about 85 pounds. would this be safe and at what dose? i have talked to her doctor and he suggested benadryl... which has the opposite affect... it makes her hyper. he then told me that she would go to sleep when her body was tired. but every day she is impossible to wake and appears tired. she does have a set bedtime and a regular routine.

I have a problem and the solution book implies that the sign flips when simplification is performed. Why?:

1/2^x < 0.01 (1 over 2 to the power of x < 0.01)
-->
2^x > 1/0.01
-->
2^x > 100

Why did the flipping of the sign happen. To my understanding, the sign only flips when you divide or multiply by a negative number. Did I miss something here or is my book wrong ?

Thanks.

the roots of eq: {(x)^n}-1=0 are called nth roots of unity. let these roots be denoted by 1,a,a1,a2........a(n-1)
1=e^(i2rpi) (r=0,1,2,3.......)

answer following-
1) value of (1-a1) (1-a2).......(1-a(n-1))is ?
2) value of sin pi/n,sin 2pi/n,sin3pi/n,........sin(n-1)pi/nis ?
3) value of a1*a2*a3*...........*a(n-1)=?
4) if a be the nth complex root of unity then (x+b)+(x2+b)a+(x3+b)a^2................+(xn+b)a^(n-1)

If so, why don’t the antibodies bind and knock off the venom in the snake? Also, why and how does the snake develop the antibodies (provided it DOES make them)? Or is the mechanism of self-protection based on a zymogenic form of the venom being secreted? If one were to inject a particular snake's venom back into it, would it die?

It is what the main character, Bart, used blow himself up with at the end of Stephen King's novel "Roadwork." It is said, in the novel, to have sixty times the explosive force of dynamite and it can only be set off with a strong electrical charge. I can’t find any thing about it, so it must be just made up, right? If you could confirm or contradict this assumption it would be greatly appreciated.
