If it is an oil lubricated compressor (which most vertical/uprights are, only a few are oil-free). Not only can it NOT be used horizontally, it cannot be transported horizonatally with oil in the crankcase. Oil will seep out of the crankcase, past piston ring, and into the pump causing hyraulic lock.
Generally not. It depends on the particular design. Ask the manufacturer.
typically, a refrigerator should be transported upright, however, in the event that it has been laid on its side for transport, leaving it upright for a period of 24 hours without running will typically allow it to be used with no ill effect. However, if the refrigerator has been plugged in and the compressor has been run "dry" it may not be salvageable.
Any position she feels comfortable to be in, which is standing or laying down on her side.
Standing up sometimes laying down
No, a Kinect sensor must be mounted in an upright position.
An individual laying face down is often refered to as laying "prone." This position is most common during sleep, and can also be an intentional position depending on the activity the individual is participating in.
in a prone position (aka semi-sitting position)
The word is recumbent.
The Horizontal recumbent position is a particular position one takes when laying down, usually in regards to medical studies. It involves laying on one's back, knees bent up and legs spread apart.
The risk with transporting it laying down is that the glass panel has a significantly higher chance of cracking than when in an upright position. Doesn't mean you can't take the risk yourself (which in reality is probably quite small) - I however, would be more inclined to pack it up in the original box for transportation (and keep it upright).
Egg shells are known to be stronger when standing upright. This is why we crack eggs open on the side.
You can lay things down, such as tiles on a floor, but if you assume a recumbent position yourself, then you are lying down.
