Plan for Management of Mineral Assess on Native Tribal Lands and for Formation of a Fully Integrated Natural Gas and Oil Exploration and Production Company
This report describes a plan for Native American tribes to assume responsibility for and operation of tribal mineral resources using the Osage Tribe as an example. Under this plan, the tribal council select and employ a qualified Director to assume responsibility for management of their mineral reservations. The procurement process should begin with an application for contracting to the Bureau of Indian Affairs. Under this plan, the Director will develop strategies to increase income by money management and increasing exploitation of natural gas, oil, and other minerals.

Magnetoresistance of One-Dimensional Subbands in Tunnel-Coupled Double Quantum Wires
We study the low-temperature in-plane magnetoresistance of tunnel-coupled quasi-one-dimensional quantum wires. The wires are defined by two pairs of mutually aligned split gates on opposite sides of a < 1 micron thick AlGaAs/GaAs double quantum well heterostructure, allowing independent control of their widths. In the ballistic regime, when both wires are defined and the field is perpendicular to the current, a large resistance peak at ~6 Tesla is observed with a strong gate voltage dependence. The data is consistent with a counting model whereby the number of subbands crossing the Fermi level changes with field due to the formation of an anticrossing in each pair of 1D subbands.

A Practical Test Method for Mode I Fracture Toughness of Adhesive Joints with Dissimilar Substrates
A practical test method for determining the mode I fracture toughness of adhesive joints with dissimilar substrates will be discussed. The test method is based on the familiar Double Cantilever Beam (DCB) specimen geometry, but overcomes limitations in existing techniques that preclude their use when testing joints with dissimilar substrates. The test method is applicable to adhesive joints where the two bonded substrates have different flexural rigidities due to geometric and/or material considerations. Two specific features discussed are the use of backing beams to prevent substrate damage and a compliance matching scheme to achieve symmetric loading conditions. The procedure is demonstrated on a modified DCB specimen comprised of SRIM composite and thin-section, e-coat steel substrates bonded with an epoxy adhesive. Results indicate that the test method provides a practical means of characterizing the mode I fracture toughness of joints with dissimilar substrates.

Development of the Pintle Release Fork Mechanism
An improved method of attachment of the pintle to the piston in the universal sampler is being developed. The mechanism utilizes a forked release disk which captures two balls in a cavity formed by a hole in the piston and a groove in the pintle rod.

Investigation of long-term time dependencies of cathodoluminescence in thin film oxide phosphors for field emission displays
Thin film oxide phosphors are prospective for low-voltage field-emission display applications due to their appropriate color coordinates, high efficiency, and possibility of creation of increased conductivity in them. Long-term stability of phosphors is also very important for practical application. Therefore, long-term stability of the most efficient thin film oxide phosphors Y{sub 2}O{sub 3}:Eu, Zn{sub 2}SiO{sub 4}:Mn, Zn{sub 2}SiO{sub 4}:Ti, and Y{sub 2}SiO{sub 5}:Ce was investigated in present work.

Neutronic safety parameters and transient analyses for Poland's MARIA research reactor.
Reactor kinetic parameters, reactivity feedback coefficients, and control rod reactivity worths have been calculated for the MARIA Research Reactor (Swierk, Poland) for M6-type fuel assemblies with {sup 235}U enrichments of 80% and 19.7%. Kinetic parameters were evaluated for family-dependent effective delayed neutron fractions, decay constants, and prompt neutron lifetimes and neutron generation times. Reactivity feedback coefficients were determined for fuel Doppler coefficients, coolant (H{sub 2}O) void and temperature coefficients, and for in-core and ex-core beryllium temperature coefficients. Total and differential control rod worths and safety rod worths were calculated for each fuel type. These parameters were used to calculate generic transients for fast and slow reactivity insertions with both HEU and LEU fuels. The analyses show that the HEU and LEU cores have very similar responses to these transients.

The secure, transportable, autonomous reactor (STAR): a small proliferation-resistant reactor system for developing countries
The Secure, Transportable, Autonomous Reactor (STAR), is an integrated concept for a small, proliferation-resistant nuclear power system capable of meeting the growing power demands of many regions of the developing world. The STAR approach builds on earlier work investigating the features required for implementation of such a system. The STAR approach includes establishing overall system requirements, conducting research into issues common to four reactor concepts (gas, liquid metal, light water and molten salt), and defining and performing the down-selection to a preferred concept that will serve as the basis for continued development leading to an eventual prototype. The paper indicates that a number of unique and distinguishing innovations are needed to both meet the energy demands of most of the world's developing regions and address growing nuclear proliferation concerns. These technical innovations form much of the basis underlying the STAR concept and include: eliminating on-site refueling and fuel access; incorporating a systems approach to nuclear energy supply and infrastructure design, with all aspects of equipment life, fuel and waste cycles included; small unit size enabling transportability; replaceable standardized modular design; resilient and robust design concepts leading to large safety margins, high reliability and reduced maintenance; simplicity in operation with reliance …

The Secure, Transportable, Autonomous Reactor System
The Secure, Transportable, Autonomous Reactor (STAR) system is a development architecture for implementing a small nuclear power system, specifically aimed at meeting the growing energy needs of much of the developing world. It simultaneously provides very high standards for safety, proliferation resistance, ease and economy of installation, operation, and ultimate disposition. The STAR system accomplishes these objectives through a combination of modular design, factory manufacture, long lifetime without refueling, autonomous control, and high reliability.

Torsion Testing of Diffusion Bonded LIGA Formed Nickel
A test technique has been devised which is suitable for the testing of the bond strength of batch diffusion bonded LIGA or DXRL defined structures. The method uses a torsion tester constructed with the aid of LIGA fabrication and distributed torsion specimens which also make use of the high aspect ratio nature of DXRL based processing. Measurements reveal achieved bond strengths of 130MPa between electroplated nickel with a bond temperature of 450 C at 7 ksi pressure which is a sufficiently low temperature to avoid mechanical strength degradation.
