Services scarcity

How long will it last An answer to this question is wanted by both suppliers and users, but it is usually a very difficult question to answer for polymer products. This is because the expected lifetime is often in tens of years, the service conditions may be complex and there is a scarcity of definitive data. 

As a result of this growing acceptance of scarcity, explicit prioritisation is becoming an increasingly common feature of the British NHS. In the past decade, we have increasingly seen health authorities make clear choices about the kind of interventions that they will provide for their inhabitants. Many have gone so far as to remove certain procedures (e.g. tattoo removal, gender reorientation and fertility treatments) from the list of services that they will provide. 

In the calculation of transition probabilities, theoretical chemists could provide a valuable service to the wider scientific community. Interest in the intensities of spectral lines lies not only in the relative scarcity of experimental data but more because of the importance of such measurements or calculations. This importance is in the realm of astrophysics. 

As a further step to conserve supplies of acetone-based cordite — due to its stability and uniformity of effect, the preferred choice for naval gunnery — the Research Department at the Royal Arsenal at Woolwich devised a new type of cordite for land service. This was known as cordite RDB. In place of highly nitrated insoluble guncotton, soluble nitrocellulose was substituted, and ether-alcohol was used as the solvent. This resulted in scarcity and higher prices for ether-alcohol, produced by the alcohol distilleries. Despite this, and although it was more expensive to manufacture, cordite RDB was accepted for use in May 1915, and put into production as a war emergency measure. ... 

Very high calling-rates per telephone line, reflecting the scarcity of telephone service.
