The technology applicable to the development of a MFDCS for orbiter application is surveyed. Technology thought to be applicable presently or in the next five years is highlighted. Areas discussed include display media, data handling and processing, controls and operator interactions and the human factors considerations which are involved in a MFDCS design. Several examples of applicable MFDCS technology are described

Application of multi-function display and control technology

The NASA orbiter spacecraft incorporates a complex array of systems, displays, and controls. The incorporation of discrete dedicated controls into a multifunction display and control system (MFDCS) offers the potential for savings in weight, power, panel space, and crew training time. Technology identified as applicable to a MFDCS is applied to the orbiter orbital maneuvering system (OMS) and the electrical power distribution and control system (EPDCS) to derive concepts for a MFDCS design. Several concepts of varying degrees of performance and complexity are discussed and a suggested concept for further development is presented in greater detail. Both the hardware and software aspects and the human factors considerations of the designs are included

Deuteron Elastic Scattering from He3 and H3

The elastic scattering of deuterons from He3 and H3 has been studied for bombarding energies up to 11 MeV. The excitation curves obtained show a broad resonance in the scattering cross section corresponding to an excitation energy of 20±0.5 MeV in both He5 and Li5. These data, together with H3(d, n)He4 and He3(d, p)He4 data from other sources, tend to indicate that D waves are responsible for the anomaly

Development of preliminary design concept for a multifunction display and control system for the Orbiter crew station. Task 4: Design concept recommendation

Application of multifunction display and control systems to the NASA Orbiter spacecraft offers the potential for reducing crew workload and improving the presentation of system status and operational data to the crew. A design concept is presented for the application of a multifunction display and control system (MFDCS) to the Orbital Maneuvering System and Electrical Power Distribution and Control System on the Orbiter spacecraft. The MFDCS would provide the capability for automation of procedures, fault prioritization and software reconfiguration of the MFDCS data base. The MFDCS would operate as a stand-alone processor to minimize the impact on the current Orbiter software. Supervisory crew command of all current functions would be retained through the use of several operating modes in the system. Both the design concept and the processes followed in defining the concept are described

Alpha scattering and capture reactions in the A = 7 system at low energies

Differential cross sections for $^3$He-$\alpha$ scattering were measured in the energy range up to 3 MeV. These data together with other available experimental results for $^3$He $+ \alpha$ and $^3$H $+ \alpha$ scattering were analyzed in the framework of the optical model using double-folded potentials. The optical potentials obtained were used to calculate the astrophysical S-factors of the capture reactions $^3$He$(\alpha,\gamma)^7$Be and $^3$H$(\alpha,\gamma)^7$Li, and the branching ratios for the transitions into the two final $^7$Be and $^7$Li bound states, respectively. For $^3$He$(\alpha,\gamma)^7$Be excellent agreement between calculated and experimental data is obtained. For $^3$H$(\alpha,\gamma)^7$Li a $S(0)$ value has been found which is a factor of about 1.5 larger than the adopted value. For both capture reactions a similar branching ratio of $R = \sigma(\gamma_1)/\sigma(\gamma_0) \approx 0.43$ has been obtained.Comment: submitted to Phys.Rev.C, 34 pages, figures available from one of the authors, LaTeX with RevTeX, IK-TUW-Preprint 930540

Scattering of He3 by He4 and of He4 by tritium

The differential elastic scattering cross section has been measured for the scattering of He3 from He4 and the scattering of He4 from tritium for bombarding energies of 5 to 18 and 4 to 18 MeV, respectively. Data were also obtained for the reactions He4(He3,p)Li6, He4(He3,p′)Li6*, H3(α,n)Li6, and H3(α,n′)Li6*. Levels are seen at 4.65, 6.64, 7.47, and 9.7 MeV in Li7, and at 4.57, 6.73, 7.21, and 9.3 MeV in Be7. A phase-shift analysis suggests assignments of 7/2- and 5/2- for the two lower levels in Li7, confirms the 5/2- assignment of the 7.47 level, and suggests a 7/2- assignment for the new level at 9.7 MeV. Similarly in Be7, the assignments of 7/2- and 5/2- for the lower two levels are confirmed, and an assignment of 7/2- is suggested for the new level at 9.3 MeV. The reduced widths for α and nucleon emission were determined by fitting the phase shifts near each level with a single- and/or double-level formula from the R-matrix formalism of Lane and Thomas. The results of the analysis are discussed and compared with predictions of recent nuclear-model calculations

Elaboração e validação de instrumento sobre conformidade às medidas de enfrentamento da covid-19 em serviços de saúde bucal no Brasil

The aim of this study was to validate an instrument designed for oral health professionals (dentists, hygienists or assistants) on compliance with measures to combat Covid-19 in dental services according to the guidelines of the Brazilian National Health Surveillance Agency. The methodological study was divided into five stages: 1) face and content validity: carried out by eight experts in the field followed by a pilot study with 35 oral health professionals; and, 2) validation of the psychometric properties measured among oral health professionals working in the states of the Southern Region of Brazil, who answered 37 questions of the instrument (n=1824), with assessment of: a) internal consistency using the Cronbach's Alpha coefficient and the item-total correlation; b) reproducibility measured by test-retest among 52 participants; and, c) construct validity by b means of  divergent and convergent correlation analysis and exploratory factor analysis. In terms of face and content validity, questions were reduced, regrouped and divided, in addition to adaptations of form and content in items and answers. On 34 items, agreement was substantial/almost complete (intraclass correlation coefficient>0.60) Reproducibility was adequate (p=0,45). Reliability analysis indicated exclusion of six items due to item-total correlation <0.20 and one item due to factor loading <0.30. The instrument with 30 items showed good internal consistency (Cronbach's alpha=0.86). Analysis of the main components  showed five dimensions that explained 51.1% of the variance (p<0.001). The convergent criterion validity had a moderate positive correlation (p<0,001). The instrument developed was validated by presenting adequate psychometric properties. In this sense, the instrument can be used for oral health professionals in other locations or at other times of the Covid-19 syndemic in Brazil.O estudo objetivou validar um instrumento elaborado para profissionais de saúde bucal (Cirurgiões-dentistas, Auxiliares e Técnicos de Saúde Bucal) sobre a conformidade às medidas de enfrentamento da Covid-19 nos serviços odontológicos segundo as diretrizes da Agência Nacional de Vigilância Sanitária do Brasil. O estudo metodológico foi dividido em cinco etapas: 1) validade de face e conteúdo: realizada por oito experts na área seguida de  estudo piloto com 35 profissionais de saúde bucal; e, 2) validação das propriedades psicométricas aferidas entre os profissionais de saúde bucal atuantes nos estados da Região Sul do Brasil que responderam 37 questões do instrumento (n=1824), com avaliação da: a) consistência interna pelo coeficiente Alfa de Cronbach e a correlação item-total; b) reprodutibilidade aferida pelo teste-reteste entre 52 participantes; e, c) validade de construto pela análise de correlação divergente e convergente e análise fatorial exploratória. Na validade de face e conteúdo houve redução, reagrupamento e divisão de questões, além de adaptações de forma e conteúdo nos itens e nas respostas. A concordância foi substancial/quase completa em 34 itens (coeficiente de correlação intraclasse>0,60). A reprodutibilidade foi adequada (p=0,45). A análise de confiabilidade indicou exclusão de seis itens por correlação item-total<0,20 e um item por carga fatorial<0,30. O instrumento com 30 itens apresentou boa consistência interna (Alfa de Cronbach=0,86). A análise de componentes principais mostrou cinco dimensões que explicam 51,1% da variância (p<0,001). A validade de critério convergente teve correlação positiva moderada (p<0,001). O instrumento elaborado apresentou-se validado ao apresentar propriedades psicométricas adequadas. Nesse sentido, o instrumento pode ser utilizado para profissionais de saúde bucal de outros locais ou em outros momentos da sindemia de Covid-19 no Brasil
