Nickel hydrogen common pressure vessel battery development

Our present design for a common pressure vessel (CPV) battery, a nickel hydrogen battery system to combine all of the cells into a common pressure vessel, uses an open disk which allows the cell to be set into a shallow cavity; subsequent cells are stacked on each other with the total number based on the battery voltage required. This approach not only eliminates the assembly error threat, but also more readily assures equal contact pressure to the heat fin between each cell, which further assures balanced heat transfer. These heat fin dishes with their appropriate cell stacks are held together with tie bars which in turn are connected to the pressure vessel weld rings at each end of the tube

The Essential HBO Reader

The founding of Home Box Office in the early 1970s was a harbinger of the innovations that transformed television as an industry and a technology in the decades that followed. HBO quickly became synonymous with subscription television and became the leading force in cable programming. Having interests in television, motion picture, and home video industries was crucial to its success. HBO diversified into original television and movie production, home video sales, and international distribution as these once-separate entertainment sectors began converging into a global entertainment industry in the mid-1980s. HBO has grown from a domestic movie channel to an international cable-and-satellite network with a presence in over seventy countries. It is now a full-service content provider with a distinctive brand of original programming and landmark shows such as The Sopranos and Sex and the City. The network is widely recognized for its award-winning, innovative and provocative programming, including dramatic series such as Six Feet Under and The Wire, miniseries such as Band of Brothers and Angels in America, comedies such as Curb Your Enthusiasm and Def Comedy Jam, sports shows such as Inside the NFL and Real Sports with Bryant Gumbel, documentary series such as Taxi Cab Confessions and Autopsy, and six Oscar-winning documentaries between 1999 and 2004. In The Essential HBO Reader, editors Gary R. Edgerton and Jeffrey P. Jones bring together an accomplished group of scholars to explain how HBO’s programming transformed the world of cable television and how the network continues to shape popular culture and the television industry. Now, after more than three and a half decades, HBO has won acclaim in four distinct programming areas—drama, comedy, sports, and documentaries—emerging as TV’s gold standard for its breakout series and specials. The Essential HBO Reader provides a comprehensive and compelling examination of HBO’s development into the prototypical entertainment corporation of the twenty-first century. Describes the complexities and ambiguities of the channel, its history, its unique business model, and its individual programs. Gary Edgerton and Jeffrey Jones have assembled a dream team of television scholars, some of whom have been paying attention to HBO since its debut in 1972. There are a lot of essay collections about television out there these days --Robert J. Thompson Director, Bleier Center for Television and Popular Culture Sy This is a splendid collection of scholarship and critical thinking. The authors have managed to tame and corral a very important aspect of American media history and yet allowed it to remain daring and unconventional. --Terry Lindvall, author of Surprised by Laughter: The Comic World of C. S. Lewis In the ever-expanding universe of cable, satellite and digital broadcasting, the authors explore how HBO fights to remain the frontrunner in innovative programming. Essential reading! --Kathryn Fuller-Seeley, author of At the Picture Show: Small Town Audiences and Coeditors Edgerton and Jones have added a critical component to the study of television and American culture. The result is a fascinating book that is indeed essential reading for anyone with an interest in media history. --Mary Ann Watson, author of Defining Visions: Television and the American Experi Comprehensive and informative on a topic that deserves to be analyzed in-depth. HBO really did write an important new chapter in television history and has not received the scholarly attention that is its due. --Michael T. Marsden, coeditor of In the Eye of the Beholder: Critical Perspectives “An important assessment of the original programming HBO has created in the past few decades—how these programs are derived and what impact they have had. Recommended.”—Choice Because Edgerton and Jones offer such a thorough treatment of HBO\u27s programming, their volume is a useful addition to a growing number of books about American television in the \u27post-network\u27 era. --American Studieshttps://uknowledge.uky.edu/upk_american_popular_culture/1014/thumbnail.jp

Nickel-hydrogen CPV battery update

The multicell common pressure vessel (CPV) nickel hydrogen battery manufactured by Johnson Controls Battery Group, Inc. has completed full flight qualification, including random vibration at 19.5 g for two minutes in each axis, electrical characterization in a thermal vacuum chamber, and mass-spectroscopy vessel leak detection. A first launch is scheduled for late in 1992 or early 1993 by the Naval Research Laboratory (NRL). Specifics of the launch date are not available at this time due to the classified nature of the program. Release of orbital data for the battery is anticipated following the launch

The significance of non-sustained hypotension in emergency department patients with sepsis

Objective Few studies have documented the incidence and significance of non-sustained hypotension in emergency department (ED) patients with sepsis. We hypothesized that ED non-sustained hypotension increases risk of in-hospital mortality in patients with sepsis. Methods Secondary analysis of a prospective cohort study. ED patients aged >17 years admitted to the hospital with explicitly defined sepsis were prospectively identified. Inclusion criteria Evidence of systemic inflammation (>1 criteria) and suspicion for infection. Patients with overt shock were excluded. The primary outcome was in-hospital mortality. Results Seven hundred patients with sepsis were enrolled, including 150 (21%) with non-sustained hypotension. The primary outcome of in-hospital mortality was present in 10% (15/150) of patients with non-sustained hypotension compared with 3.6% (20/550) of patients with no hypotension. The presence of non-sustained hypotension resulted in three times the risk of mortality than no hypotension (risk ratio = 2.8, 95% CI 1.5–5.2). Patients with a lowest systolic blood pressure <80 mmHg had a threefold increase in mortality rate compared with patients with a lowest systolic blood pressure ≥80 mmHg (5 vs. 16%). In logistic regression analysis, non-sustained hypotension was an independent predictor of in-hospital mortality. Conclusion Non-sustained hypotension in the ED confers a significantly increased risk of death during hospitalization in patients admitted with sepsis. These data should impart reluctance to dismiss non-sustained hypotension, including a single measurement, as not clinically significant or meaningful

Modeling Accuracy and Variability of Motor Timing in Treated and Untreated Parkinson’s Disease and Healthy Controls

Parkinson’s disease (PD) is characterized by difficulty with the timing of movements. Data collected using the synchronization–continuation paradigm, an established motor timing paradigm, have produced varying results but with most studies finding impairment. Some of this inconsistency comes from variation in the medication state tested, in the inter-stimulus intervals (ISI) selected, and in changeable focus on either the synchronization (tapping in time with a tone) or continuation (maintaining the rhythm in the absence of the tone) phase. We sought to re-visit the paradigm by testing across four groups of participants: healthy controls, medication naïve de novo PD patients, and treated PD patients both “on” and “off” dopaminergic medication. Four finger tapping intervals (ISI) were used: 250, 500, 1000, and 2000 ms. Categorical predictors (group, ISI, and phase) were used to predict accuracy and variability using a linear mixed model. Accuracy was defined as the relative error of a tap, and variability as the deviation of the participant’s tap from group predicted relative error. Our primary finding is that the treated PD group (PD patients “on” and “off” dopaminergic therapy) showed a significantly different pattern of accuracy compared to the de novo group and the healthy controls at the 250-ms interval. At this interval, the treated PD patients performed “ahead” of the beat whilst the other groups performed “behind” the beat. We speculate that this “hastening” relates to the clinical phenomenon of motor festination. Across all groups, variability was smallest for both phases at the 500-ms interval, suggesting an innate preference for finger tapping within this range. Tapping variability for the two phases became increasingly divergent at the longer intervals, with worse performance in the continuation phase. The data suggest that patients with PD can be best discriminated from healthy controls on measures of motor timing accuracy, rather than variability

Search for nearby Earth analogs I. 15 planet candidates found in PFS data

30 pages, 20 figures, 3 tables, accepted for publication in ApJSThe radial velocity (RV) method plays a major role in the discovery of nearby exoplanets. To efficiently find planet candidates from the data obtained in high-precision RV surveys, we apply a signal diagnostic framework to detect RV signals that are statistically significant, consistent in time, robust in the choice of noise models, and do not correlated with stellar activity. Based on the application of this approach to the survey data of the Planet Finder Spectrograph, we report 15 planet candidates located in 14 stellar systems. We find that the orbits of the planet candidates around HD 210193, 103949, 8326, and 71135 are consistent with temperate zones around these stars (where liquid water could exist on the surface). With periods of 7.76 and 15.14 days, respectively, the planet candidates around star HIP 54373 form a 1:2 resonance system. These discoveries demonstrate the feasibility of automated detection of exoplanets from large RV surveys, which may provide a complete sample of nearby Earth analogs.Peer reviewedFinal Accepted Versio

The Apollo Medical Operations Project: Recommendations to Improve Crew Health and Performance for Future Exploration Missions and Lunar Surface Operations

Medical requirements for the future Crew Exploration Vehicle (CEV), Lunar Surface Access Module (LSAM), advanced Extravehicular Activity (EVA) suits and Lunar habitat are currently being developed. Crews returning to the lunar surface will construct the lunar habitat and conduct scientific research. Inherent in aggressive surface activities is the potential risk of injury to crewmembers. Physiological responses and the operational environment for short forays during the Apollo lunar missions were studied and documented. Little is known about the operational environment in which crews will live and work and the hardware will be used for long-duration lunar surface operations. Additional information is needed regarding productivity and the events that affect crew function such as a compressed timeline. The Space Medicine Division at the NASA Johnson Space Center (JSC) requested a study in December 2005 to identify Apollo mission issues relevant to medical operations that had impact to crew health and/or performance. The operationally oriented goals of this project were to develop or modify medical requirements for new exploration vehicles and habitats, create a centralized database for future access, and share relevant Apollo information with the multiple entities at NASA and abroad participating in the exploration effort
