Photoemission study of MnBi and GdNi2Ge2

Photoelectron spectroscopy was performed on single crystals of MnBi and GdNi2Ge2 utilizing synchrotron radiation as the light source. MnBi is known for its large magneto-optical Kerr rotation and GdNi 2Ge2 is studied for its intriguing magnetic properties at low temperature, including a spin density wave (SDW) that is reported to occur at 27.1 K. Angle resolved photoemission was used to investigate the electronic band structures of both materials. Resonant photoemission was used to characterize valence band features. The shallow core levels were also investigated using angle integrated photoemission. Results from MnBi measurements are compared with recent theoretical bandstructure and density of states calculations. GdNi2Ge2 results are compared to the theoretical band structure calculations. They support theoretical handling of the Gd-4f levels as being part of the atomic core. The search for the SDW was inconclusive

Angle-resolved photoemission study of the rare-earth intermetallic compounds: RNi2Ge2(R=Eu,Gd)

Experimental energy bands mapped from normal-emission photoelectron spectra of EuNi2Ge2 and GdNi2Ge2(001)surfaces show four photoemission features that disperse in both materials in good agreement with band calculations. Segments of the Fermi surfaces mapped by angle-resolved photoemission spectroscopy in the ΓXPZ plane of the Brillouin zones for both EuNi2Ge2 and GdNi2Ge2 are in good agreement with band calculations. This Fermi surface segment changes when one electron is added to EuNi2Ge2, corresponding to GdNi2Ge2, based on the rigid-band approximation

Spinal cord stimulation for treatment of the pain associated with hereditary multiple osteochondromas

OBJECTIVE: Hereditary multiple osteochondromas (HMO) usually presents with neoplastic lesions throughout the skeletal system. These lesions frequently cause chronic pain and are conventionally treated with surgical resection and medication. In cases where conventional treatments have failed, spinal cord stimulation (SCS) could be considered as a potential option for pain relief. The objective of this case was to determine if SCS may have a role in treating pain secondary to neoplastic lesions from HMO. CASE PRESENTATION: We report a 65-year-old female who previously received both surgical and pharmacological interventions for treating HMO neoplastic pain in the lumbar, pelvis, femur, and tibial regions. These interventions either failed to offer significant pain relief or caused excessive lethargy. A SCS trial was then offered with a dual 16-contact lead trial leading to 70%–80% improvement in pain from baseline and 85% reduction in oxycodone IR intake. This was followed by permanent implantation of two 2×8 contact paddle leads (T7–T8 and T9–T10 interspaces). After 8-week follow-up, settings were further optimized resulting in an additional 30% improvement in pain compared to last visit. At 6-month follow-up, the patient reported continued pain relief. CONCLUSION: This case demonstrates the first successful use of SCS to treat both HMO and nonmalignant neoplastic-related pain. The patient reported pain improvement from baseline, reduced pain medication requirements, and subjective improvement in quality of life. Additionally, this case demonstrates the potential advantage of trialing multiple painful areas with a 16-contact lead in order to avoid multiple trials and placement

An Outline Development Plan for the CNGLA Region

The CNGLA is an organization of citizens from central Nebraska representing Loup, Garfield, Wheeler, Greeley, Valley, Ouster, Howard, and Sherman counties concerned with the future of their region. The mission of the CNGLA is to initiate and promote the development of the region and to stimulate the economy and quality of life of all of its residents. It is a key objective of the CNGLA to develop a plan for accomplishing its mission. In the summer of 1990, the CNGLA engaged the Department of Community and Regional Planning of the College of Architecture at the University of Nebraska- Lincoln to assist in the development of the plan. This study was undertaken by a group of second year graduate planning students in the Principles and Practices of Regional Planning and Development (CRP 911) class. While providing an important public service to the CNGLA region and the State of Nebraska, this project also partly fulfills the requirements of a Masters Degree in Community and Regional Planning at the University. Study Description This study is organized into two distinct phases: (1) the Assessment and Analysis Phase, and (2) the Planning and Programming Phase. In the Assessment and Analysis Phase the systems approach was employed. The systems approach involves the identification and study of four sub-systems as follows: 1. Physical/Environmental Subsystem 2. Social/Demographic Subsystem 3. Economic/Financial Subsystem 4. Political/Jurisdictional Subsystem. Relevant data was collected and analyzed relating to each of these four subsystems. Data came from many sources including active participation by citizens in the region at town meetings and site visits, library research, as well as information provided by various public agencies and organizations. The objective of the Assessment and Analysis Phase was to determine the problems and prospects for development in the region. The identification of problems and prospects led to the development of goals and objectives for the region. The problems and prospects along with goals and objectives identified in the Assessment and Analysis Phase were verified and amended by a delegation representing the CNGLA. A revised goals and objectives statement was drafted which became the agenda for the Planning and Programming Phase. The Planning and Programming Phase involved the formulation of development strategies to meet the goals and objectives defined in the previous phase. Upon developing goals and sub-goals five key subject areas were identified: 1. Economic Development 2. Health, Human Services, and Housing 3. Tourism Development 4. Solid Waste Management 5. Implementation. Each of these subject areas are addressed in the form of projects and programs that may be implemented by the CNGLA along with other public and private entities. The final result of this phase is an outline development plan for the CNGLA region. This plan was presented at a town meeting by the planning team. This report chronicles both phases of this undertaking and is the final product of this study. This study was a professional planning project undertaken by graduate students and faculty in an academic setting over a duration of 15 weeks. Some recommendations of this study may require additional research and analysis. This study is intended to act as an agenda for action by the CNGLA. It offers a vast array of ideas, strategies, programs, and projects that my be implemented by the CNGLA or other agencies or organizations within the region. It is hoped that the recommendations of this study will be utilized to provide for further enhancement of the quality of life in the CNGLA region
