A more accurate method for estimating in situ coal density and mineral ...
A leastsquares hyperbolic formula is derived from the dry coal and mineral properties in order to estimate the dry sample density. The formula accepts two in situ moisture percentages, for both coal and rock, in order to estimate in situ density for coal and other lithologies. This method has several advantages over existing techniques.
How to Dry Chillies The Chilli Expert
Start by wrapping the string around the three stems a couple of times, then bring the string up between two of the chillies, and finish off with a halfhitch over the stems. Continue using the same piece of string, tying up groups of three chillies until it gets too awkward to handle. Just cut the string and start again.
