If we were to assume that all humans have an immortal soul that departs the body at death, what would happen if someone who had been cryogenically frozen at death was brought back to life at a later time? Would the soul return to them or remain where it was?

Samples come in in large numbers. They must be dissected and put into individual tiny tubes. The original samples have a barcode. The tubes are currently put in batches of 90 and are labelled with a batch number and 1-90. This is time consuming. How can the original barcode data be used to identify the final tubes? Anybody else do something similar without a member of staff having to stand there with a label gun?

Humans have only evolved over a few thousand yrs, yet we were able to evolve into high order thinkers. There have been animals that have been around for 100's of millions of years. Crocs have been around since the dino's yet they are still dumb. Squids and oct's are thought of as very smart yet they have been around for millions of yrs and have NOT developed into high order thinkers.

If two clocks were calibrated for accuracy, then one clock was moved from one level of gravity to another, eg earth to moon would it measure time at the same rate in relationship to the other clock?

if my location is 1150 feet above sea level

most of the surrounding towns and cities are at about 1000-1200 feet above sea level.

my geography around me is hilly.

my antenna is 50 feet above the ground and is 22 feet tall, it is an omnidirectional antenna.

i beleive the entire 22 feet radiates the R.F.

i am transmitting at 28.555mhz with a 150 watt deadkey and1000 peak @ 90% modulation

not counting for skipping off the ionsphere ( no skip)

how far away theroetically, could the signal be recived by a similar station.

how about the antenna at 70' which should be right at a 2 wavelengths which would be ideal.

i hope i have included enough info

Let S,T, and U be sets. Let e be a mpa from S to T, let f be a map from T to U.

Show that, if e and f are injective, then so is ef.
Show that, if e and f are surjective, then so is ef.
Show that, if e and f are bijective, then so is ef.

I have no clue where to start. I do know that if e and f are injective, then so is ef because its a rule, but I'm not sure how to prove that.
