ALSEP termination report

The Apollo Lunar Surface Experiments Package (ALSEP) final report was prepared when support operations were terminated September 30, 1977, and NASA discontinued the receiving and processing of scientific data transmitted from equipment deployed on the lunar surface. The ALSEP experiments (Apollo 11 to Apollo 17) are described and pertinent operational history is given for each experiment. The ALSEP data processing and distribution are described together with an extensive discussion on archiving. Engineering closeout tests and results are given, and the status and configuration of the experiments at termination are documented. Significant science findings are summarized by selected investigators. Significant operational data and recommendations are also included

Resistive Magnetohydrodynamic Equilibria in a Torus

It was recently demonstrated that static, resistive, magnetohydrodynamic equilibria, in the presence of spatially-uniform electrical conductivity, do not exist in a torus under a standard set of assumed symmetries and boundary conditions. The difficulty, which goes away in the ``periodic straight cylinder approximation,'' is associated with the necessarily non-vanishing character of the curl of the Lorentz force, j x B. Here, we ask if there exists a spatial profile of electrical conductivity that permits the existence of zero-flow, axisymmetric r esistive equilibria in a torus, and answer the question in the affirmative. However, the physical properties of the conductivity profile are unusual (the conductivity cannot be constant on a magnetic surface, for example) and whether such equilibria are to be considered physically possible remains an open question.Comment: 17 pages, 4 figure

CONFLICT OF LAWS - NEGOTIABLE INSTRUMENTS - SITUS OF BEARER BONDS UNDER THE TRADING WITH THE ENEMY ACT

ln a suit on a negotiable instrument, a problem arises as to just how many places can claim valid jurisdiction. Thus, where the domiciles of the parties to a negotiable instrument are diverse, there are several jurisdictional possibilities. For example, with regard to a negotiable bearer bond it may be said that there is sufficient contact with the parties and/or the property (1) at the place where it was issued, (2) at the present location of the certificate of indebtedness, (3) at the location of the debtor corporation\u27s office or principal place of business, or (4) in the state of incorporation of the debtor corporation. Logically, the location of either the certificate of indebtedness or the debtor himself would seem to be the preferable choices, and the conflict between them has been a source of frequent controversy. It is generally felt that the location of the certificate itself should be allowed to govern, but the purpose for which the decision is being made has occasionally altered a court\u27s view in this respect. The purpose of this discussion is to point to the problems inherent in specifying the situs of the property interest of a negotiable bearer bond, particularly with relation to the subjection of such property interest to the provisions of the Trading With the Enemy Act

CIVIL PROCEDURE-JURISDICTION-COMMISSION OF ISOLATED TORT BY FOREIGN CORPORATION AS DOING BUSINESS WITHIN THE STATE

Plaintiff, a Vermont resident, brought action for damages in the Vermont court, alleging negligence of defendant in re-roofing plaintiff\u27s house located in that state. Defendant, a Massachusetts corporation, had not qualified to do business in Vermont, nor had it appointed an agent to receive service therein. There was no evidence to indicate that defendant was actively engaged in business there. Substituted service was made upon defendant through the Secretary of State of Vermont as authorized by a statute. The statute stipulated that the term doing business included those instances in which a foreign corporation made a contract in Vermont with a resident thereof which called for performance within the state; or in which a foreign corporation committed a tort in whole or in part in Vermont. There was no question concerning adequacy of notice and opportunity to appear. Held, a state may constitutionally pass a statute subjecting a foreign corporation which commits a tort wholly within the state to the jurisdiction of its courts for the purpose of determining liability for damages arising froiμ such a tort.

TAXATION-FEDERAL INCOME TAX-DEDUCTIBILITY OF CONTRIBUTIONS TO PROFIT-SHARING TRUSTS

Plaintiff corporation set up a profit sharing trust for the benefit of its employees as authorized under section 165(a) of the Internal Revenue Code. The plan for the trust, as approved by the Treasury, provided that plaintiff should contribute annually an amount equal to 15 % of net income, as defined, not to exceed 15% of basic salary or wages of all eligible participating employees. For the tax year 1944 plaintiff claimed deductions under section 23(p)(1)(C) for an amount equal to 15% of the total participating payroll, which is actually the allowable maximum, but which in this case exceeded 15% of the net income figure. The Collector of Internal Revenue reduced the allowable deduction to the latter amount and declared a deficiency, which the plaintiff paid. This action was brought in the federal district court to secure a refund. Held, the amount by which the contribution exceeded 15% of net profits was not authorized by the approved plan and did not constitute an allowable deduction as an ordinary and necessary business expense under the Internal Revenue Code.

Longtime behavior of nonlocal Cahn-Hilliard equations

Here we consider the nonlocal Cahn-Hilliard equation with constant mobility in a bounded domain. We prove that the associated dynamical system has an exponential attractor, provided that the potential is regular. In order to do that a crucial step is showing the eventual boundedness of the order parameter uniformly with respect to the initial datum. This is obtained through an Alikakos-Moser type argument. We establish a similar result for the viscous nonlocal Cahn-Hilliard equation with singular (e.g., logarithmic) potential. In this case the validity of the so-called separation property is crucial. We also discuss the convergence of a solution to a single stationary state. The separation property in the nonviscous case is known to hold when the mobility degenerates at the pure phases in a proper way and the potential is of logarithmic type. Thus, the existence of an exponential attractor can be proven in this case as well

Bulk phase behaviour of binary hard platelet mixtures from density functional theory

We investigate isotropic-isotropic, isotropic-nematic and nematic-nematic phase coexistence in binary mixtures of circular platelets with vanishing thickness, continuous rotational degrees of freedom and radial size ratios $\lambda$ up to 5. A fundamental measure density functional theory, previously used for the one-component model, is proposed and results are compared against those from Onsager theory as a benchmark. For $\lambda \leq 1.7$ the system displays isotropic-nematic phase coexistence with a widening of the biphasic region for increasing values of $\lambda$. For size ratios $\lambda \geq 2$, we find demixing into two nematic states becomes stable and an isotropic-nematic-nematic triple point can occur. Fundamental measure theory gives a smaller isotropic-nematic biphasic region than Onsager theory and locates the transition at lower densities. Furthermore, nematic-nematic demixing occurs over a larger range of compositions at a given value of $\lambda$ than found in Onsager theory. Both theories predict the same topologies of the phase diagrams. The partial nematic order parameters vary strongly with composition and indicate that the larger particles are more strongly ordered than the smaller particles
