Semiconductor devices for optical communications in 1 micron band of wavelength

Crystal growth and the characteristics of semiconductor lasers and diodes for the long wavelength band used in optical communications are examined. It is concluded that to utilize the advantages of this band, it is necessary to have a large scale multiple wavelength communication, along with optical cumulative circuits and optical exchangers

Beitrag zum Problem über den Einflnss der Inhalation von mit CO(2) versetzter Luft auf verschiedene Symptome, die sicn bei Unterdruck einstellen

Im Jahre 1935 stellte Professor Dr. Oinuma mit seinem Kollegen bei der Besteigung des Fuji (3776 Meter uber dem Meeresspiegel) fest, dass die Inhalation von mit CO(2) versetzter Luft einen gunstigen Einfluss auf die Bergkrankheit ausubt. Wir stellten bezuglich dieses Punktes experimentelle Untersuchungen in der Unterdruckkammer unseres Laboratoriums an, unter Mithilfe unserer Kollegen als Versuchspersonen. Dabei wurden die Zusammensetzung und das Volumen der Expirationsluft, der Prozentsatz von O(2) und CO(2) der Alveolarluft (nach der Haldane'schen Methode), sowie auch die Gase im arteriellen Blut (nach der Slyke'schen Methode) gemessen. Die Resultate lassen sich folgendermassen zusammen fassen: 1) Bei allen Versuchspersonen tritt bei Unterdruck, infolge der Hyperventilation der Lunge, stets "Akapnie" ein, 2) Wird bei Unterdruck Luft eingeatmet, welcher CO(2) zugesetzt wurde, so nimmt die Atembewegung und der CO(2)- und der O(2)-gehalt der Expirationsluft und der Alveolarluft zu. Der respiratorische Quotient aber bleibt unverandert. Dies führt natürlich zu einer Zunahme des CO(2)- und O(2)-gehaltes im Blut. Diese Sauerstoffzunahme im Blut ubt demnach u. E. einen gunstigen Einfluss auf die verschiedenen Symptome aus, die unter vermindertem Luftdruck entstehen

Numerical investigation of thermodynamic effect on unsteady cavitation in cascade

In the present study, the thermodynamic effect on unsteady cavitation is investigated in cascade in water and liquid nitrogen at different freestream temperatures. Cavitation flowfield is simulated based on self-developed locally homogeneous model of a compressible gasliquid two-phase medium, which is available to treat unsteady cavitation. For calculation of thermodynamic effect on cavitation, simplified thermodynamic model for the locally homogenous medium is used where local saturated vapor pressure changes with depending on rate of heat transfer by evaporation and condensation. In the result of the numerical analysis, the difference of cavitating flowfields is reproduced numerically in water and liquid nitrogen at different freestream temperature concerning the cavity surface profile and distribution of the evaporation region. Also the thermodynamic effect on cavitation in water and liquid nitrogen is investigated by comparing the cavity volumes. Then, well known thermodynamic effect on cryogenic cavitation can be reproduced numerically in liquid nitrogen, where development of the cavity is suppressed according to increase of freestream temperature. On the other hand, the inverse thermodynamic effect, which is experimentally observed in single hydrofoil in water, is reproduced under the condition of unsteady cavitation in water in the present study.http://deepblue.lib.umich.edu/bitstream/2027.42/84272/1/CAV2009-final78.pd

Numerical prediction of cavitation erosion in cavitating flow

In this study bubble behavior in cavitating flow is analyzed and prediction of cavitation erosion in 2D cavitating flow around ClarkY 11.7 % hydrofoil at several cavitation is performed by impact pressure induced by bubble collapse. Our numerical method predicts that the impact energy is small if variation of cavitating flow is small and that the position of peak impact energy moves downstream with the decrease in cavitation number until the maximum sheet cavity length becomes larger than chord length. When the maximum sheet cavity length becomes larger than chord length, there are not obvious peak values and relatively weak erosion occurs. And it is found that high impact pressures are mainly induced by bubbles in a cloud and in the vicinity of sheet cavity termination during a cloud collapse. Therefore large impact energy occurs when the cloud cavity collapses near the hydrofoil, the sheet cavity termination is on the hydrofoil and the number of bubble is large in these cavities.http://deepblue.lib.umich.edu/bitstream/2027.42/84264/1/CAV2009-final67.pd

Keadilan Distributif dan Komitmen Organisasional sebagai Pemoderasi Pengaruh Partisipasi Penganggaran pada Senjangan Anggaran

Budget used by local government of Denpasar as an instrument of accountability in the area of ??financial management systems as well as basic public services. This research was conducted in the regional work units (SKPD) in Denpasar. This study aimed to examine the effect of budgetary participation on budgetary slack with distributive justice and organizational commitment as moderating. Methods of data collection in this study using survey method with a questionnaire measuring instrument. The number of samples in this study was 269 echelons of all SKPD in Denpasar chosen by purposive sampling technique. The analysis technique used is Moderated Regression Analysis (MRA). The results showed that the budgeting participation give positive influence on budgetary slack. Distributive justice able to weaken the effect of budgetary participation on budgetary slack. . Organizational commitment is also able to weaken the effect of budgetary participation on budgetary slack
