Antimisting kerosene
The antimisting additive ((FM-9) was tested in terms of its propulsion systems performance. The effect of the additive on engine operation was evaluated, operating problems were identified, the adaptability of engines to antimisting kerosene was assessed, and the potential viability of this fuel for use in present and future fan jet engines was determined
Differences between financial systems in Europe : consequences for EMU
Major differences between national financial systems might make a common monetary policy difficult. As within Europe, Germany and the United Kingdom differ most with respect to their financial systems, the present paper addresses its topic under the assumption that the United Kingdom is already a part of EMU. Employing a comprehensive concept of a financial system, the author shows that there are indeed profound differences between the national financial systems of Germany and the United Kingdom. But he argues that these differences are not likely to create great problems for a common monetary policy. In the context of the present paper, one important difference between the two financial systems refers to the structure of the respective financial sector and, as a consequence, to the strength with which a given monetary policy impulse set by the central bank is passed on to the financial sector. The other important difference refers to the typical relationship between the banks and the business sector in each country which determines to what extent the financial sectors and especially the banks pass on pressure exerted on them by a monetary policy authority to their clients in their national business sector. In Germany, the central bank has a stronger influence on the financial sector than in England, while, for systemic reasons, German banks tend to soften monetary policy pressures on their customers more than British banks do. As far as the transmission of a restrictive monetary policy of the ECB to the real economy is concerned, these two differences tend to offset each other. This is good news for the advocates of a monetary union as it eases the task of the ECB when it comes to determining the strength of its monetary policy measures
Getting Ready for Physics - Commissioning of the ALICE Experiment
ALICE at CERN-LHC is an experiment dedicated to the study of high-energy
heavy-ion collision. In this paper we will briefly describe the experimental
layout and give an overview on the installation status of the ALICE detector
components including an outlook towards the completion of the staged detector
setup. We will review the commissioning of the detector components with
emphasis on the central detectors, in particular the time projection chamber
(TPC). The commissioning took place in summer 2008 awaiting the first beams
from the LHC in the fall. The result from commissioning are compared with the
performance figures, which are outlined in the ALICE Physics Performance

The use of AntiMisting Kerosene (AMK) in turbojet engines
The effect of antimisting kerosene (AMK) flow characteristics on fan jet engines and the impact of degradation requirements on the fuel system was evaluated. It was determined from the present program that AMK fuel cannot be used without predegradation, although some degradation occurs throughout the fuel feed system, expecially in the fuel pumps. There is a tendency toward FM-9 AMK additive agglomeration and gel formation when the liquid flows at a critical velocity through very small passages. The data indicate this phenomenon to be a function of the degree of degradation, the passage size, the differential pressure, the fluid temperature, and the accumulated flow time. Additionally, test results indicate that the long term cumulative effects of this phenomenon may require more degradation than the theoretical requirement determined from short term tests
Two-stage emitter follower is temperature stabilized
Two-stage temperature stabilized circuit using two transistors is described. Increase in temperature causes the base-to-emitter voltage of n-p-n transistor to become less positive whereas the base-to-emitter voltage of p-n-p transistor becomes less negative, so the temperature-induced variation in V sub 1 and V sub 2 cancel out
Evaluation of decay curves of a chemical species undergoing simultaneous first- and second-order decay
IBM 1620 computer prepares tables to enable fast calculation of the first- and second-order rate constants from two half-lives and the corresponding initial concentrations, obtained from either one or two decay curves
