To the Editor: We read with considerable interest the report of the Order of St Francis (OSF) Stroke Network in Peoria,1 discussing their early experience promoting the use of intravenous tissue plasminogen activator (IV tPA) in central Illinois. Sin

Trialkylstannanes R 3 SnH (RMe, Bu) and 9-BBN add to the BN double bond in dimethylaminobis(trifluoromethyl)borane (CF 3 ) 2 BNMe 2 ( A ) to yield (CF 3 ) 2 BH·NMe 2 SnR 3 and (CF 3 ) 2 BH·NMe 2 9-BBN respectively. Both hydrolyse to yield

BSCCO-2223 tapes have been produced by the ‘powder-in-tube’ method with reproducible critical current densities of > 1 × 10 4 A cm −2 at 77 K and 5 × 10 4 A cm −2 at 4.2 K. Superconductivity at 77 K was retained in fields o fup to 7 T. The

The superconducting properties of the Bi(Pb)-2223 phase have been optimized. Prolonged annealing of coarse powder raised the j/sub c/ in bulk samples to as high as 1100 A-cm/sup -2/ at 77 K. The temperature dependence between 96 and 4.2 K was studied

The compounds M[(N-t-Bu) 2 SiMe 2 ] 2 (I M = Ti; II, M = Zr) were prepared by treatment of dilithiated Me 2 Si(NH-t-Bu) 2 with TiCl 4 and ZrCl 4 , respectively. Crystals of I and II belong to the space groups P 2 1 2 1 2 1 and C 2/ c , respectively.

An investigation has been made of the RF properties of two oxide superconductors, mainly Y/sub 1/Ba/sub 2/Cu/sub 3/O/sub 7/ and tentatively Bi/sub 2/CaSr/sub 2/Cu/sub 2/O/sub x/, between 4.2 and 300 K at S-, K-, and W-band frequencies. The surface re
