Uranus science planning

Recommendations for a 1979 Mariner Jupiter-Uranus mission are discussed with the possibility of launching the first outer planet atmospheric entry probe. Measurement categories considered for the mission include conducting imaging experiments, observations in both the IR and UV spectral range, experiments associated with magnetic fields, plasma, charged particles, and S- and X-band occultation measurements

Thermodynamic evaluation of transonic compressor rotors using the finite volume approach

Research at NASA Lewis Research Center gave the opportunity to incorporate new control volumes in the Denton 3-D finite-volume time marching code. For duct flows, the new control volumes require no transverse smoothing and this allows calculations with large transverse gradients in properties without significant numerical total pressure losses. Possibilities for improving the Denton code to obtain better distributions of properties through shocks were demonstrated. Much better total pressure distributions through shocks are obtained when the interpolated effective pressure, needed to stabilize the solution procedure, is used to calculate the total pressure. This simple change largely eliminates the undershoot in total pressure down-stream of a shock. Overshoots and undershoots in total pressure can then be further reduced by a factor of 10 by adopting the effective density method, rather than the effective pressure method. Use of a Mach number dependent interpolation scheme for pressure then removes the overshoot in static pressure downstream of a shock. The stability of interpolation schemes used for the calculation of effective density is analyzed and a Mach number dependent scheme is developed, combining the advantages of the correct perfect gas equation for subsonic flow with the stability of 2-point and 3-point interpolation schemes for supersonic flow

Production of hollow components for rolling element bearings by diffusion welding

A hollow rolling element for a bearing is fabricated by diffusion welding hollow shells together. The hollow shell halves are joined by faying surfaces and diffusion welding

The employment effects of terminating disability benefits

This paper examines the employment of individuals in the United States who lost disability insurance eligibility after the 1996 removal of drug and alcohol addictions as qualifying conditions. Abstract Few Social Security Disability Insurance (DI) beneficiaries return to the labor force, making it hard to assess their likely employment in the absence of benefits. Using administrative data, I examine the employment of individuals who lost DI eligibility after the 1996 removal of drug and alcohol addictions as qualifying conditions. Approximately 22 percent started working at levels that would have disqualified them for DI, an employment response that is large relative to their work histories. Those who received DI for 2-3 years had the largest response, suggesting that a period of public assistance may maximize the employment of some disabled individuals

Conflicts of Interests in the Representation of Children

C ONFLICTS of interests arise whenever the representation of a client may be materially limited by the lawyer\u27s duties to either another client or a third person or by the interests of the lawyer herself.\u27 Analyzing such conflicts typically requires identifying situations involving a potentially impermissible conflict, determining whether the conflict is consentable, and, if it is, obtaining consent after full disclosure.2 Conflicts analysis is difficult enough when the client is an adult.3 When the client is a child, however, the analysis is complicated by a number of factors. For example, in the wide variety of cases in which children (or their interests) are involved, the child\u27s role varies enormously. In some cases, the child is actually a party; in others, the child has a legal interest of some sort; in still others, the outcome will affect the child only indirectly. Moreover, a child\u27s interests can be protected in a variety of fashions, some of which involve legal representation, some of which involve appointment of a guardian ad litem (who may be a lawyer), and some of which involve indirect protection through the participation of the parent. Even when it is clear that the lawyer\u27s role is actual representation, it may be unclear to whom the lawyer turns when decisions on behalf of the child are to be made. In some cases, the child may sue (or be sued) only through the parent as guardian or next friend. In other cases, the child may be named as a party, but the parent may assert the right to make some or all decisions on the child\u27s behalf. In still others, the child may not be a party at all, but the court may permit or assign a lawyer to represent either the child or the child\u27s guardian or guardian ad litem. Finally, the lawyer may choose or be asked to represent more than one party; for example, the lawyer may attempt to represent both parent and child, agency and child, or multiple siblings. All these situations involve at least the potential for conflicting interests; however, only some of the issues raised are amenable to resolution through conflict of interests analysis. Moreover, even among those issues that do fall within the purview of conflict of interests rules, there are several unique aspects of the representation of children which ultimately call for an analysis far more complex than that typically encountered in even the most intractable conflicts issues involving adults

Joining precipitation-hardened nickel-base alloys by friction welding

Solid state deformation welding process, friction welding, has been developed for joining precipitation hardened nickel-base alloys and other gamma prime-strengthened materials which heretofore have been virtually unweldable. Method requires rotation of one of the parts to be welded, but where applicable, it is an ideal process for high volume production jobs

Fabrication of hollow ball bearings by diffusion welding

Two steel hemispheres are diffusion welded in an atmosphere of 0.00002 torr at a temperature of 2130 degrees F for 4 hours with a pressure of 4 psi holding the hemispheres together. Weld is accomplished with only microdeformation

Ethical Issues in Mass Tort Plaintiffs’ Representation: Beyond the Aggregate Settlement Rule

Those who have addressed ethics issues for plaintiffs’ lawyers in mass tort litigation have focused on possible reform of the aggregate settlement rule to facilitate global settlements. This Article addresses a broader range of ethical issues, including (1) application of the general conflicts of interest rule to both client-client and client-lawyer conflicts; (2) unresolved issues concerning the interpretation of the current aggregate settlement rule, including the need to disclose client names and the applicability of the rule to court-approved settlements and formula or matrix allocations; and (3) the ability of lawyers to voluntarily withdraw from representing plaintiffs who reject an offer of settlement
