Feasibility study of a long duration balloon flight with NASA/GSFC and Soviet Space Agency Gamma Ray Spectrometers

A feasibility study of conducting a joint NASA/GSFC and Soviet Space Agency long duration balloon flight at the Antarctic in Jan. 1993 is reported. The objective of the mission is the verification and calibration of gamma ray and neutron remote sensing instruments which can be used to obtain geochemical maps of the surface of planetary bodies. The gamma ray instruments in question are the GRAD and the Soviet Phobos prototype. The neutron detectors are supplied by Los Alamos National Laboratory and the Soviet Phobos prototype. These are to be carried aboard a gondola that supplies the data and supplies the power for the period of up to two weeks

Filament wound data base development, revision 1

The objective was to update the present Space Shuttle Solid Rocket Booster (SRB) baseline reentry aerodynamic data base and to develop a new reentry data base for the filament wound case SRB along with individual protuberance increments. Lockheed's procedures for performing these tasks are discussed. Free fall of the SRBs after separation from the Space Shuttle Launch Vehicle is completely uncontrolled. However, the SRBs must decelerate to a velocity and attitude that is suitable for parachute deployment. To determine the SRB reentry trajectory parameters, including the rate of deceleration and attitude history during free-fall, engineers at Marshall Space Flight Center are using a six-degree-of-freedom computer program to predict dynamic behavior. Static stability aerodynamic coefficients are part of the information required for input into this computer program. Lockheed analyzed the existing reentry aerodynamic data tape (Data Tape 5) for the current steel case SRB. This analysis resulted in the development of Data Tape 7

Virtual Pitch and Pitch Shifts in Church Bells

It is well established that musical sounds comprising multiple partials with frequencies approximately in the ratio of small integers give rise to a strong sensation of pitch even if the lowest or fundamental partial is missing—the so-called virtual pitch effect. Experiments on thirty test subjects demonstrate that this virtual pitch is shifted significantly by changes in the spacing of the constituent partials. The experiments measured pitch by comparison of sounds of similar timbre and were automated so that they could be performed remotely across the Internet. Analysis of the test sounds used shows that the pitch shifts are not predicted by Terhardt’s classic model of virtual pitch. The test sounds used were modelled on the sounds of church bells, but a further experiment on seventeen test subjects showed that changes in partial amplitude only had a minor effect on the pitch shifts observed, and that a pitch shift was still observed when two of the lowest frequency partials were removed, so that the effects reported are of general interest

Session C6- Restoring habitat, improving passage and implementing hatchery reform in the Klickitat Subbasin: a Yakama tribal approach

The Yakama Nation Fisheries Program (YNFP) is one of the largest fisheries programs of native people in North America. For over four decades it has held true to its mission to Honor, Protect, and Restore the fisheries that are, vital to sustaining the Yakama’s way of life. Thefree-flowing Klickitat Subbasin in SW Washington is an important Columbia River tributary for the Yakamas, as it remains the last best place to harvest fish for ceremonial, subsistence and commercial purposes using traditional methods, and thereby ensuring a place to pass down this important part of their culture. Research conducted through the Bonneville Power Administration funded Yakima/Klickitat Fisheries Project (YKFP) determined the abundance, spatial structure and diversity of Klickitat anadromous stocks. Research information is guides a prioritized approach to enhance habitat abundance, function and complexity. Additionally, the YKFP has recently completed major reconstruction of two non-compliant fishways into modem fish passage facilities incorporating; remote sensing, eelways, and brood collection capabilities to meet future hatchery reform goals. A total of over 55 miles of mainstem passage have been opened; with an additional 12 miles of tributary passage opened in the Klickitat Basin. Since its inception in 1983, the YKFP has lead the effort to reform hatchery practices to make certain that the stated hatchery objectives (i.e. harvest augmentation, native stock supplementation, or ESA-listed stock conservation) meets treaty obligations and local community goals, while being scientifically defensible. This presentation will highlight the importance of building partnerships among tribal members and local stakeholders, development of the overarching policy framework guiding this project and describe the unique nature of state and tribal YKFP co-management. An overview of the intended benefits in fish production through hatchery reform measures and increased habitat abundance and effectiveness to support increased natural production in the Klickitat Basin will also be described

Are We Worthy Leaders?

Today as never before America stands as the champion of democracy. Again we have successfully defended our democratic ideals against the forces of oppression. Not only have we protected them for ourselves, but it is now our aim to spread this freedom to the less fortunate people of the world who have never enjoyed it before. Our ancestors drenched this land of ours with their own blood in order that we might be a free nation. Now it is our noble purpose to make this freedom universal. Before we set ourselves up as an example, let us look over our record and make sure that we are really worthy of leadership. If we carefully examine some of our very recent history, we might detect certain distasteful elements which other nations would not want to adopt

The Character Of Tailholt

All those who really knew John Taylor are dead and forgotten. His generation have by this time advanced a considerable way down the line of history. Not all has been forgotten, however; as the story was passed on to me by my grandfather\u27s narrations, I feel as though I really knew old John myself

The New Recruit

The new recruit has just entered a completely different phase of life in which he immediately becomes extremely insecure. He has no idea what is coming next, and this insecure feeling is so radically different from the security of the average American home that he suffers a considerable amount of anxiety until he is able to make an adequate adjustment to service life. He is no longer allowed to say what he pleases when he feels the urge to do so, and the resulting suppressed emotion often makes him irritable toward his fellow cohorts

Empathy and self-acceptance: necessary qualities of a peer helper

This thesis is a preliminary study of the qualities of people who chose to be peer helpers. A review of the literature on helping theories led to the conclusion that empathy and self-acceptance were necessary elements of a helper. This study hoped to lend support to this theory. The hypothesis stated that students electing to take a peer helping training course would have different levels of empathy and self-acceptance than those in a cooking class. These qualities were measured using a psychological inventory, and the scores of 115 adolescent subjects (n=115) were compared. There was no significant difference between students choosing different electives. Implications of these findings are discussed, as well as formats for future studies
