International Solar Terrestrial Physics (ISTP) geotail mission

The Geotail spacecraft will be provided by the Institute of Space and Astronautical Science (ISAS) and will provide a Delta Launch Vehicle, tracking support by the Deep Space Network (DSN), and data processing support by GSFC. In exchange, ISAS will reserve part of the payload for NASA instruments together with a certain number of investigators from the United States. As the solar wind flows toward the Earth, some of the energy is modified by the Earth's magnetosphere, ionosphere, and upper atmosphere. This interaction causes the flow to be altered, creating a plasmasphere, plasma sheet, and ring currents in the Earth's Geomagnetic Tail region. The result is a series of distinct regions which affect processes on the Earth. By traversing the tail region to a variety of depths, Geotail will be able to determine the size, position, and other properties of these regions. When correlated with information obtained from the other ISAS spacecraft, Geotail data should help to provide a more complete understanding of how the solar processes affect the Earth's environment. The flight profile is given, and information is presented in tabular form on the following topics: DSN support, frequency assignments, telemetry, command, and tracking support responsibility

Volunteer management in the white mountain national forest districts: A study on the effectiveness and efficiency of volunteer service

The purpose of this research project is to identify and examine the volunteer management in the White Mountain National Forest Districts. Volunteers have played a major role in the forest service for years, providing labor for a mutually beneficial cause. Research was conducted to better understand whether volunteers are used in effective and efficient way in the White Mountain National Forest Districts. This project reviewed current literature on volunteer management and volunteers in the forest service. Informational interviews were conducted with forest service staff and a survey amongst volunteers was performed to gather data. The results of the surveys are included in the data and analysis section and conclusions are made from those results in management of volunteers

Method and apparatus for battery charge control Patent

Battery charging system with cell to cell voltage balanc

Circuit prevents overcharging of secondary cell batteries

Circuit prevents battery cell overcharging by detecting and reducing the charging voltage to the open-circuit voltage of the battery when this current falls to a predetermined value. The voltage control depends on the fact that the charging current falls significantly when the battery nears its fully charged state
