Some Ether Anecdotes

Anecdotes

The well-known Arpanet was the first operational packet-switching network. 1 Almost completely unknown is what we claim was the second operational packet-switching network, the LFK Network—although, admittedly , it was a fairly minimal network. Work on the LFK Network began in fall 1970, and it was installed and accepted by fall 1972. It was used as part of a logistics system relating to the No...

Anecdotes

Evaluating anecdotes and case reports.

Stories are more memorable than statistics. Newspaper or magazine articles about some new chemotherapy for cancer typically will include an interview with a patient who is doing well on it. Websites of alternative practitioners and clinics sometimes feature stories by or about patients describing their successful treatment. These stories can be very persuasive to readers, but some scientists di...

Charge transfer in some complexes of crown ether and of thiacrown ether with dihalogens: DFT study.

The present study was carried out by focusing on the interaction between molecular complexes crown and thiacrown ethers such as 15-crown-5 (15C5), thia-15-crown-5 (T15C5), dithia-15-crown-5 (DT15C5) with homogeneous and heterogeneous dihalogens (XY) such as I2, IBr, ICl, Br2, Cl2 in the gas phase and in dichloromethane solvent through applying density function theory (DFT) as well as Gaussian 9...

Antitumor activity and some pharmacologic properties of anthramycin methyl ether.

The antitumor antibiotic, anthramycin methyl ether (AME), was shown to be active in increasing survival time in mice bearing various experimental leukemias. Like actinomycin D, it was active against P388 but inactive against P388/38280. AME also was active against the plasma cell tumor LCP, while having no activity against the plasma cell tumor YPC-1. AME bad an IDso of 0.02/~g/ml against L1210...
