Nickel oxide films were prepared by electrochemically precipitating the hydroxide and heating it in air to form the oxide. The resulting oxide films behave as a capacitor. The capacitance of the oxide depends on the heating temperature, showing a maximum at 3008C. The mechanism of charge storage was studied by measuring the capacitance and surface area as a function of heating temperature, and ...

We show that if a Barker sequence of length n > 13 exists, then either n = 189 260 468 001 034 441 522 766 781 604, or n > 2 · 1030. This improves the lower bound on the length of a long Barker sequence by a factor of more than 107. We also show that all but fewer than 1600 integers n ≤ 4 ·1026 can be eliminated as the order of a circulant Hadamard matrix. These results are obtained by completi...

Results The prevalence of various pregnancy complications was 8. 6% for birth prematurely, 9. 2% for hypertension or preeclampsia, IUGR 5. 8% and 7. 3% for loss pregnancy. PAPP A levels were lower in fetal loss group (P = 0. 005), vascular disease group(P = 0. 001) and preterm delivery group(P = 0. 001). In addition, a lower rate of bHCG was associated with the occurrence of placental pathologi...

The equipment control (EC) software of the GSI accelerators has been written entirely in Pascal. Modern software development is based on C++ or Java. To be prepared for the future, we decided to convert the EC software from Pas-cal to C in a first step. Considering the large amount of software, this is done automatically as far as possible. The paper describes our experiences gained using a Pas...
