The left side number will give the last digit of the frame size. On some frames, this might show up as 5C, but it means the same.
One of the thornier issues which comes up in legal practice from time to time is the backdating of documents.
Because it sets a standard way for me to record this info, no other reason.
Model year bikes are begun production the year before, and as such its possible for their date code to be somewhat different than what the pattern suggests Pattern? The left side of the serial gives model and (sometimes) size information.
Marine isotope stages (MIS), marine oxygen-isotope stages, or oxygen isotope stages (OIS), are alternating warm and cool periods in the Earth's paleoclimate, deduced from oxygen isotope data reflecting changes in temperature derived from data from deep sea core samples.
Working backwards from the present, which is MIS 1 in the scale, stages with even numbers have high levels of oxygen-18 and represent cold glacial periods, while the odd-numbered stages are troughs in the oxygen-18 figures, representing warm interglacial intervals.
Legally speaking, this is something that you should not do – or more accurately, there will only ever rarely be occasions when this is appropriate to do.
However in practice, for both good reasons and bad, backdating of documents does occur.
The DM100™ Enhanced Series desktop mailing systems provide so much more!
The risks of backdating (or misdating) documents accidentally is multiplied in modern commercial transactions by the practice of getting all the documents signed before “completion” and then rushing around dating them afterwards.
My father (who was also a lawyer) used to love telling a story about how he was able to triumphantly prove to the court that a yacht charter was backdated by showing the stamps which had been used to pay the nominal 15¢ stamp duty were in fact first issued by the post office some four months after the date stated on the face of the document.
The data are derived from pollen and foraminifera (plankton) remains in drilled marine sediment cores, sapropels, and other data that reflect historic climate; these are called proxies.
The MIS timescale was developed from the pioneering work of Cesare Emiliani in the 1950s, and is now widely used in archaeology and other fields to express dating in the Quaternary period (the last 2.6 million years), as well as providing the fullest and best data for that period for paleoclimatology or the study of the early climate of the Earth, Emiliani's work in turn depended on Harold Urey's prediction in a paper of 1947 that the ratio between oxygen-18 and oxygen-16 isotopes in calcite, the main chemical component of the shells and other hard parts of a wide range of marine organisms, should vary depending on the prevailing water temperature in which the calcite was formed.
