YAMACRAW 11 Narrative

USCGC YAMACRAW (W333) left Woods Hole the evening of 28 September 1958 on a three-week cruise. The plan of the cruise included several days of classified work in deep water south of Woods Hole (not reported here ), a short bathymetric survey on the Blake Plateau, a stop in Jacksonville, Florida for personnel exchange, and a five-day survey in the Tongue of the Ocean, with the cruise ending at Savannah, Georgia. The track of YAMACRA W is shown in Figure 1. This was to be the last cruise of YAMACRAW for the Woods Hole Oceanographic Institution. All equipment was to be removed at Savannah, Georgia to be placed aboard USNS CHAIN (TARS 20). The scientific party leaving Woods Hole consisted of seven persons : Dr. William Richardson, Chief Scientist, Lee Davis, Paul Stimson, Richard Weller , and Charles Wilkins from WHO!; Dr. James Lafferty and Dr. George Gaines from the General Electric Company.Office of Naval Research Under Contra:ct Nonr-1367(00

Liquid metal magnetohydrodynamics (LMMHD) technology transfer feasibility study. Volume 1: Summary

The potential application of liquid metal magnetohydrodynamics (LMMHD) to central station utility power generation through the period to 1990 is examined. Included are: (1) a description of LMMHD and a review of its development status, (2) LMMHD preliminary design for application to central station utility power generation, (3) evaluation of LMMHD in comparison with conventional and other advanced power generation systems and (4) a technology development plan. One of the major conclusions found is that the most economic and technically feasible application of LMMHD is a topping cycle to a steam plant, taking advantage of high temperatures available but not usable by the steam cycle

Preliminary report CHAIN #11 : 22 February - 22 March 1960

The second half of CHAIN Cruise #11, 22 February until 22 March, 1960, is detailed as to type of measurements made with their specific locations. The cruise areas were in the St. Croix region, the Puerto' Rico Trench and the tracks from the Bahamas to Bermuda to Woods Hole. Camera lowerings, lowerings of the thermal probe and accompanying cores, dredging, sound velocimeter lowerings, and acoustic studies of the scattering layer were the special events undertaken while precision bathymetry and towing of the Continuous Temperature Recording Chain were on a watch standing basis.Undersea Warfare Branch, Office of Naval Research Under Contract Nonr- 1367(00) (NR- 261-10 2

Technology Transfer in Poland: An Investment of U.S. Government, U.S. Corporate, and Polish Government Strategies

This case study examines how U.S. Government (USG) policy, U.S. corporate policy, and Polish government policy affect the strategy of technology transfer of military and/or dual-use technologies in Poland. The traditional supplier/recipient relationship is explored and found to be insufficient to describe the process associated with military and/or dual-use technology transfer. An alternate model is proposed that accounts for the activities of the USG, U.S. corporations, and the Polish government. These relationships are investigated in the context of six strategies to determine the validity of the model in the case of military and/or dual-use technology transfer to Poland. The analysis provides evidence that in an increasingly globalized economy, appropriate strategies for technology transfer are critical for each participant to attain their particular objectives. Further, these strategies are influenced by intra-participant forces that shape goals and inter-participant relations that both create and inhibit opportunities to transfer technology

On the Sensitivity of the HAWC Observatory to Gamma-Ray Bursts

We present the sensitivity of HAWC to Gamma Ray Bursts (GRBs). HAWC is a very high-energy gamma-ray observatory currently under construction in Mexico at an altitude of 4100 m. It will observe atmospheric air showers via the water Cherenkov method. HAWC will consist of 300 large water tanks instrumented with 4 photomultipliers each. HAWC has two data acquisition (DAQ) systems. The main DAQ system reads out coincident signals in the tanks and reconstructs the direction and energy of individual atmospheric showers. The scaler DAQ counts the hits in each photomultiplier tube (PMT) in the detector and searches for a statistical excess over the noise of all PMTs. We show that HAWC has a realistic opportunity to observe the high-energy power law components of GRBs that extend at least up to 30 GeV, as it has been observed by Fermi LAT. The two DAQ systems have an energy threshold that is low enough to observe events similar to GRB 090510 and GRB 090902b with the characteristics observed by Fermi LAT. HAWC will provide information about the high-energy spectra of GRBs which in turn will lead to understanding about e-pair attenuation in GRB jets, extragalactic background light absorption, as well as establishing the highest energy to which GRBs accelerate particles

High resolution Doppler lidar

A high resolution lidar system was implemented to measure winds in the lower atmosphere. The wind speed along the line of sight was determined by measuring the Doppler shift of the aerosol backscattered laser signal. The system in its present configuration is stable, and behaves as indicated by theoretical simulations. This system was built to demonstrate the capabilities of the detector system as a prototype for a spaceborne lidar. The detector system investigated consisted of a plane Fabry-Perot etalon, and a 12-ring anode detector. This system is generically similar to the Fabry-Perot interferometer developed for passive wind measurements on board the Dynamics Explorer satellite. That this detector system performs well in a lidar configuration was demonstrated

Attitudes about voice and voice therapy among transgender individuals

Due to increased interest in the area of voice problems and treatment among transgender individuals in recent years, a study about vocal experiences, vocal handicap, and participation in treatment methods among this population is needed. This study examined vocal handicap among transgender women, transgender men, and individuals identifying as a non-binary gender through an online questionnaire. The goals of the study were to compare vocal handicap between transgender men and women as well as those who had participated in voice therapy and those who had not. Another goal was to identify reasons among transgender individuals for not participating in voice therapy. Analysis of the answers from 233 participants of the survey revealed a wide range of attitudes and opinions about voice and voice therapy. Among transgender women, there was no significant difference in voice handicap among participants who had participated in voice therapy and those who had not. In transgender men, on the other hand, there was a significant difference between vocal handicap in participants who had experienced voice changes secondary to hormone therapy and those who had not; however, a surprising 39% of transgender men still had a Transgender Self-Evaluation Questionnaire score indicating a severe vocal handicap. No significant difference between Transgender Self-Evaluation Questionnaire scores was noted between transgender women and transgender men. A third group, those who identified outside the gender binary, emerged, and appeared to also have a range of experiences and attitudes about voice, both positive and negative

Very high energy gamma-ray follow-up observations of novae and dwarf novae with the MAGIC telescopes

In the last few years the Fermi-LAT instrument has detected GeV gamma-ray emission from several novae. Such GeV emission can be interpreted in terms of inverse Compton emission from electrons accelerated in the shock or in terms of emission from hadrons accelerated in the same conditions. The latter might reach much higher energies and could produce a second component in the gamma-ray spectrum at TeV energies. We perform follow-up observations of selected novae and dwarf novae in search of the second component in TeV energy gamma rays. This can shed light on the acceleration process of leptons and hadrons in nova explosions. We have performed observations with the MAGIC telescopes of 3 sources, a symbiotic nova YY Her, a dwarf nova ASASSN-13ax and a classical nova V339 Del, shortly after their outbursts. We did not detect TeV gamma-ray emission from any of the objects observed. The TeV upper limits from MAGIC observations and the GeV detection by Fermi constrain the acceleration parameters for electrons and hadrons.Comment: Proceedings of the 34th International Cosmic Ray Conference, 30 July- 6 August, 2015, The Hague, The Netherlands.
