Liquid-vapor interface locations in a spheroidal container under low gravity

As a part of the general study of liquid behavior in low gravity environments, an experimental investigation was conducted to determine if there are equilibrium liquid-vapor interface configurations that can exist at more than one location in oblate spheroidal containers under reduced gravity conditions. Static contact angles of the test liquids on the spheroid surface were restricted to near 0 deg. The experiments were conducted in a low gravity environment. An oblate spheroidal tank was tested with an eccentricity of 0.68 and a semimajor axis of 2.0 cm. Both quantitative and qualitative data were obtained on the liquid-vapor interface configuration and position inside the container. The results of these data, and their impat on previous work in this area, are discussed. Of particular interest are those equilibrium interface configurations that can exist at multiple locations in the container

NASA Lewis Research Center low-gravity fluid management technology program

A history of the Lewis Research Center in space fluid management technology program is presented. Current programs which include numerical modeling of fluid systems, heat exchanger/radiator concept studies, and the design of the Cryogenic Fluid Management Facility are discussed. Recent analytical and experimental activities performed to support the Shuttle/Centaur development activity are highlighted

Diffraction Analysis of 2-D Pupil Mapping for High-Contrast Imaging

Pupil-mapping is a technique whereby a uniformly-illuminated input pupil, such as from starlight, can be mapped into a non-uniformly illuminated exit pupil, such that the image formed from this pupil will have suppressed sidelobes, many orders of magnitude weaker than classical Airy ring intensities. Pupil mapping is therefore a candidate technique for coronagraphic imaging of extrasolar planets around nearby stars. Unlike most other high-contrast imaging techniques, pupil mapping is lossless and preserves the full angular resolution of the collecting telescope. So, it could possibly give the highest signal-to-noise ratio of any proposed single-telescope system for detecting extrasolar planets. Prior analyses based on pupil-to-pupil ray-tracing indicate that a planet fainter than 10^{-10} times its parent star, and as close as about 2 lambda/D, should be detectable. In this paper, we describe the results of careful diffraction analysis of pupil mapping systems. These results reveal a serious unresolved issue. Namely, high-contrast pupil mappings distribute light from very near the edge of the first pupil to a broad area of the second pupil and this dramatically amplifies diffraction-based edge effects resulting in a limiting attainable contrast of about 10^{-5}. We hope that by identifying this problem others will provide a solution.Comment: 23 pages, 13 figures, also posted to http://www.orfe.princeton.edu/~rvdb/tex/piaaFresnel/ms.pd

Section 40.1 of the American Law Institute\u27s Corporate Governance Project: Restatement or Misstatement?

The American Law Institute\u27s (ALI\u27s) corporate governance project has generated the most heated debate in the history of that distinguished institution. Critics claim that the document is a radical proposal for reforming corporate law in a way that increases legal intrusions into the management of business, while supporters claim that the document is fairly reflective of much of the existing law, and that it clarifies and simplifies that law. This article focuses on what thus far has been the most heated part of the debate-the ALI\u27s treatment of the duties and liabilities of corporate directors, set out in section 4.01 of the Principles of Corporate Governance. My thesis is that events of the 1960\u27s and \u2770\u27s led to attempts by both corporate officials and their attorneys to fend off what they saw as radical law reform, focused on federal chartering, with a series of aspirational documents intended to reassure critics that corporate managers and their attorneys were good and responsible citizens who were aware of their responsibilities. Accepting Berle & Mean\u27s view of their own power, corporate managers claimed the mantle of good citizenship that Berle had ultimately bestowed upon them

Is the Second Amendment Outdated or Misinterpreted?

This Article examines the evidence of original intent behind the Second Amendment, which Justice Antonin Scalia ignored in District of Columbia v. Heller. It suggests that the adoption of the Second Amendment was motivated by states\u27 concerns about federal control over state and local militias. Thus, it was intended as a state’s rights amendment before Justice Scalia disregarded the opening clause. The Article then examines the results of Justice Scalia’s opinion in terms of a widespread increasing homicide rate in a nation with more firearms in circulation than the total population. Finally, it compares current homicide rates in the United States with those of other nations, particularly those with more restrictive gun laws, where homicide rates are considerably lower

Public Health Considerations of the Kenduskeag Stream, Bangor, November 1960

Introduction More than 350 years ago the first white man excreted his wastes into the Kenduskeag Stream. Today, the City of Bangor offers its citizens the same sewage treatment facilities as that given to the crewmen of Samuel de Champlain\u27s ship in 1604. This report attempts to describe the extent of pollution in the Kenduskeag Stream and point out the potential health hazard of this foul smelling watercourse that divides our city with the sewage of our citizens.

Fairness Opinions: How Fair Are They and Why We Should Do Nothing About It

I believe that fairness opinions exist for two reasons: a judicial belief in the determinacy of value, and legal rules that shelter the business judgment of a board when based on reliance on the opinion of experts. Except in rare instances, investment bankers do not deliver fairness opinions for the benefit of public shareholders. Further, the nature of the fairness opinion is such that neither courts nor investors should attach too much weight to it nor impose liability because of it, except in instances of fraud
