Oxidation of 1,N6-ethenoadenosine monophosphate (epsilon AMP) with periodate cleaved the cis-diol of the ribose ring and resulted in the formation of a dialdehyde derivative (epsilon AMP-dial). At room temperature epsilon AMP-dial was unstable and underwent beta-elimination to give 4',5'-anhydro-1,N6-ethenoadenosine dialdehyde acetal (A epsilon Ado-dial). These nucleotide analogues were found t...

the dial by two screws, but in the faulty vaporizer one had fallen out, into the top of the casing. With the cam loose, it was possible to turn the dial a few degrees clockwise beyond the OFF position, when a strong smell of enflurane was noticed in the fresh gas flow. Anaesthetists should be aware that unless the OFF mark on the concentration setting dial coincides with the datum mark, then th...

Dial balances are preferred for speed in today's crowded school laboratory. Dial-O-Gram 310 is preferred for speed, accuracy, and the ruggedness which withstands student handling and makes expensive service contracts unnecessary. The unique accuracy of Dial-O-Gram 310 is the result of extensive research by Ohaus on the cause and correction of errors in spiral spring mechanisms. Only Ohaus uses ...

Dial-a-ride systems attract great attentions as a style of new transportation systems for urban areas. While it is reported that such systems improve usability of bus systems when applied in a small town or area, it is not obvious how and under what conditions the system are reasonable in comparison to traditional fixed-route bus systems. We conducted several computer simulations of dial-a-ride...
