Turbulence Intensity at Inlet of 80- by 120-Foot Wind Tunnel Caused by Upwind Blockage

In order to estimate the magnitude of turbulence in the National Full-Scale Aerodynamics Complex (NFAC) 80- by 120-Foot Wind Tunnel (80 x 120) caused by buildings located upwind from the 80 x 120 inlet, a 150th-scale study was performed that utilized a nominal two-dimensional blockage placed ahead of the inlet. The distance of the blockage ahead of the inlet was varied. This report describes velocity measurements made in the plane of the 80 x 120 model inlet for the case of zero ambient (atmospheric) wind

Boeing Smart Rotor Full-scale Wind Tunnel Test Data Report

A full-scale helicopter smart material actuated rotor technology (SMART) rotor test was conducted in the USAF National Full-Scale Aerodynamics Complex 40- by 80-Foot Wind Tunnel at NASA Ames. The SMART rotor system is a five-bladed MD 902 bearingless rotor with active trailing-edge flaps. The flaps are actuated using piezoelectric actuators. Rotor performance, structural loads, and acoustic data were obtained over a wide range of rotor shaft angles of attack, thrust, and airspeeds. The primary test objective was to acquire unique validation data for the high-performance computing analyses developed under the Defense Advanced Research Project Agency (DARPA) Helicopter Quieting Program (HQP). Other research objectives included quantifying the ability of the on-blade flaps to achieve vibration reduction, rotor smoothing, and performance improvements. This data set of rotor performance and structural loads can be used for analytical and experimental comparison studies with other full-scale rotor systems and for analytical validation of computer simulation models. The purpose of this final data report is to document a comprehensive, highquality data set that includes only data points where the flap was actively controlled and each of the five flaps behaved in a similar manner

Venus High Temperature Atmospheric Dropsonde and Extreme-Environment Seismometer (HADES)

The atmospheric composition and geologic structure of Venus have been identified by the US National Research Council's Decadal Survey for Planetary Science as priority targets for scientific exploration, however the high temperature and pressure at the surface, along with the highly corrosive chemistry of the Venus atmosphere, present significant obstacles to spacecraft design that have severely limited past and proposed landed missions. Following the methodology of the NASA Innovative Advanced Concepts (NIAC) proposal regime and the Collaborative Modeling and Parametric Assessment of Space Systems (COMPASS) design protocol, this paper presents a conceptual study and initial feasibility analysis for a Discovery-class Venus lander capable of an extended-duration mission at ambient temperature and pressure, incorporating emerging technologies within the field of high temperature electronics in combination with novel configurations of proven, high Technology Readiness Level (TRL) systems. Radioisotope Thermal Power (RTG) systems and silicon carbide (SiC) communications and data handling are examined in detail, and various high-temperature instruments are proposed, including a seismometer and an advanced photodiode imager. The study combines this technological analysis with proposals for a descent instrument package and a relay orbiter to demonstrate the viability of an integrated atmospheric and in-situ geologic exploratory mission that differs from previous proposals by greatly reducing the mass, power requirements, and cost, while achieving important scientific goals

Factores sociodemográficos y de la enfermedad relacionados al estilo de vida de personas hemodializadas, Hospital Regional de Loreto - 2018

The objective was to determine the relationship between sociodemographic factors (age, sex, origin, level of education) and disease (time of illness and time on hemodialysis) with the lifestyle of people on hemodialysis. The method was quantitative and the descriptive, correlational design, the sample was 70 people on hemodialysis. The instruments were a sociodemographic and disease data sheet and a questionnaire on the lifestyle of the person on hemodialysis. The results were: 35.4% (28 people), were aged 61 years or older, 50.6% (40 people) were male, 57.0% (45 people) came from the marginal urban area, the 58.2% (46 people) had a secondary education degree, 79.7% (63 people), had less than 5 years with the disease and 44.3% (35 people) had less than one year of hemodialysis, 53.2% (42 people) presented an unhealthy lifestyle. In conclusion, a significant statistical relationship was found between age p = 0.014, sex p = 0.018, origin p = 0.004, degree of education p = 0.003, time of illness p = 0.006, time on hemodialysis p = 0.017, and lifestyle.El objetivo fue, determinar la relación entre los factores sociodemográficos (edad, sexo, procedencia, grado de instrucción) y de la enfermedad (tiempo de enfermedad y tiempo en hemodiálisis) con el estilo de vida de personas hemodializadas. El método fue el cuantitativo y el diseño descriptivo, correlacional, la muestra fueron 70 personas en hemodiálisis. Los instrumentos fueron una ficha de datos sociodemográficos y de la enfermedad y un cuestionario sobre estilo de vida de la persona hemodializadas. Los resultados fueron: El 35.4% (28 personas), tuvieron edades de 61 años a más, el 50,6% (40 personas) fueron de sexo masculino, el 57,0% (45personas) procedían de la zona Urbano marginal, el 58,2% (46 personas) tenían grado de instrucción secundaria, el 79,7% (63 personas), tenían menos de 5 años con la enfermedad y el 44,3% (35 personas) presentaban menos de un año de hemodiálisis, el 53,2% (42 personas) presentaron estilo de vida no saludable. En conclusión, se encontró relación estadística significativa entre edad p = 0,014, sexo p = 0,018, procedencia p = 0,004, grado de instrucción p = 0,003, tiempo de enfermedad p = 0,006, tiempo en hemodiálisis p = 0,017, con el estilo de vida

CARE AND ASSISTANCE IN THE TITLES OF DISSERTATIONS IN NURSING (1984-2011)

O estudo analisa a frequência de aplicação dos termos cuidado e assistência nos títulos das dissertações produzidas no Programa de Pós Graduação em Enfermagem – Mestrado, da UNIRIO. Método: quantitativo; abordagem da história serial; temporalidade 1984 a 2011; fonte preferencial 407 dissertações (N=n); na análise foi aplicado o teste qui-quadrado, com nível de significância igual a 5%. Resultados: evidenciou-se três fases, o termo assistência predominou sobre o cuidado na primeira (1984 a 1994), o termo cuidado supera o termo assistência na segunda (1995 a 2001) e na terceira (2002 a 2011). Conclusão: Nos primeiros anos, a proporção dos dois termos, indicou o efeito do entendimento das ideias de Wanda Horta, posteriormente, outros fatores contextuais e conceituais, associados às reestruturações do Programa contribuíram para ascensão da aplicação do termo cuidado, situando a produção no debate contemporâneo sobre as concepções de cuidados de enfermagem e sua relação com o termo assistência de enfermagem
