No absolute figure can be given, but it should depend on n-butanolprice plus converting fee plus extra cost for small quantities,like Butanol Price plus 2 $ per kg.
that is is good because it can solve many murders and serve justice to those . bad because it may be used to discriminate against people with inferior genetics.
You need symbols on PFDs and PIDs because an exact drawing is more complex than necessary on those documents. Too much space would be occupied by the detailed sketch of something as simple as a valve, when all that those two documents need to show is what kind of valve, how large it is, and where in...
The significance of transfatty acids in oils is that we cannot metabolize them. Their counterpart is "cis fats", which are curled, but trans fats are straight. Since they aren't metabolized, they're stored in low-density lipids (LDL) -- the "bad" kind of triglycerides on the doctor's lab reports --...
