Abstract:
Zusammenfassung. Der Short-Form Health Survey SF-8 ist ein Instrument zur Messung der gesundheitsbezogenen Lebensqualität, einem wichtigen Outcomekriterium klinischer Studien und in den Gesundheitswissenschaften. Das Instrument ist eine Kurzform des häufig verwendeten SF-36, mit dem acht Dimensionen der subjektiven Gesundheit gemessen sowie zwei Summenskalen Körperlicher und Psychischer Gesundheit berechnet werden können. Der SF-8 wurde im Jahr 2004 im Rahmen einer bundesweit durchgeführten Mehrthemenbefragung eingesetzt. Basierend auf diesen Daten können erstmalig repräsentative Normdaten zum SF-8 (N = 2552) aus einer schriftlichen Befragung für die deutsche Bevölkerung vorgelegt werden. Die Referenzdaten werden alters- sowie geschlechtsdifferenziert berichtet und auf Zusammenhänge mit soziodemografischen Merkmalen analysiert. Seltene fehlende Werte in den Antworten weisen auf eine gute Akzeptanz des Instruments hin. Auch wenn der SF-8 in verschiedenen Subskalen mit Deckeneffekten behaftet ist, kann sein Einsatz aufgrund seiner Ökonomie empfohlen werden.

Abstract:
To determine the influence of a 17-day exposure to real and simulated spaceflight (SF) on cardiorespiratory function during exercise, four male crewmembers of the STS-78 space shuttle flight and eight male volunteers were studied before, during, and after the 17-day mission and 17 days of −6° head-down-tilt bed rest (BR), respectively. Measurements of oxygen uptake, pulmonary ventilation, and heart rate were made during submaximal cycling 60, 30, and 15 days before the SF liftoff and 12 and 7 days before BR; on SF days 2, 8, and 13 and on BR days 2, 8, and 13; and on days 1, 4, 5, and 8 after return to Earth and on days 3 and 7 after BR. During 15 days before liftoff, day 4 after return, and day 8 after return and all BR testing, each subject completed a continuous exercise test to volitional exhaustion on a semirecumbent (SF) or supine (BR) cycle ergometer to determine the submaximal and maximal cardiorespiratory responses to exercise. The remaining days of the SF testing were limited to a workload corresponding to 85% of the peak pre-SF peak oxygen uptake (V̇o2 peak) workload. Exposure to and recovery from SF and BR induced similar responses to submaximal exercise at 150 W. V̇o2 peak decreased by 10.4% from pre-SF (15 days before liftoff) to day 4 after return and 6.6% from pre-BR to day 3 after return, which was partially (SF: −5.2%) or fully (BR) restored within 1 wk of recovery. Workload corresponding to 85% of the peak pre-SF V̇o2 peak showed a rapid and continued decline throughout the flight (SF day 2, −6.2%; SF day 8, −9.0%), reaching a nadir of −11.3% during testing on SF day 13. During BR, V̇o2 peak also showed a decline from pre-BR (BR day 2, −7.3%; BR day 8, −7.1%; BR day 13, −9.0%). These results suggest that the onset of and recovery from real and simulated microgravity-induced cardiorespiratory deconditioning is relatively rapid, and head-down-tilt BR appears to be an appropriate model of this effect, both during and after SF.

Abstract:
Objective. This study is aimed at determining factors associated with the quality of life among Jordanian diabetic patients with foot ulcers. Methods. 144 consecutive patients with diabetic foot ulcers aged ≥ 18 years who were attending the diabetic foot clinic at a diabetes-specialized center were included in this study. Health-related quality of life was assessed using two self-administered questionnaires: Diabetic Foot Scale-Short Form (DFS-SF) and Short Form-8 (SF-8). Results. Patients with diabetic foot ulcer had low mean DFS-SF score and low mean scores on physical and mental component summary scales (PCS8 and MCS8). Males had significantly higher DFS-SF score indicating better health-related quality of life than females (P value 0.038). A patient with stressful life events had significantly lower health-related quality of life using DFS-SF scale and SF-8 summary scales. Patients with peripheral vascular disease (PVD) and patients with obesity had lower DFS-SF and PCS8 quality of life. Conclusion. Patients with diabetic foot ulcer had low quality of life. Female gender, obesity, presence of PVD, and stressful life events were the most important factors associated with lower quality of life in patients with diabetic foot ulcer.

Abstract:
Trabalho Final do Mestrado Integrado em Medicina apresentado à Faculdade de Medicina
Introdução: O ensino nas faculdades de medicina exige ao aluno esforço e dedicação em tempo integral, o que por vezes, leva a um comprometimento do bem-estar físico e social desses estudantes. O presente estudo utiliza os questionários EQ-5D e SF-8 para avaliar a qualidade de vida dos estudantes de Medicina da Universidade de Coimbra nos anos clínicos (4º, 5º e 6º anos) durante o ano letivo 2016/2017.Objetivo: Avaliar a qualidade de vida dos estudantes do ciclo clínico do MIM da FMUC (4º a 6º ano) e perceber a correlação entre EQ5D-3L e SF-8 em função das variáveis epidemiológicas idade, sexo, habitação em tempo de estudo, atividades sociais extra-curriculares, satisfação com a vida estudantil e social bem como a preocupação com o futuro. Métodos: Realizou-se um estudo observacional com intenção analítica, em amostra de conveniência mas representativa da população de estudantes do 4º, 5º e 6º anos do curso de Medicina da Faculdade de Medicina da Universidade de Coimbra, no ano letivo de 2016/2017. Foi elaborado um questionário tendo por base as questões do EQ-5D e SF-8, que foi aplicado através da plataforma “formulários Google”. Os dados obtidos foram submetidos a análise descritiva e estatística, usando os testes de Kruskal-Wallis, Mann-Witney e ANOVA e as correlações de Pearson e de Spearman.Resultados: Os 105 alunos dos 3 anos de curso estudados e ambos os sexos têm a mesma distribuição de respostas para os Scores SF e Eq5D. Não há diferenças estatisticamente significativas entre estes scores relativamente ao tipo de residência em tempo de aulas. Ambos os scores se correlacionam inversamente. Quanto ao “estado de saúde neste momento”: há correlação negativa com o score SF e correlação positiva com o score EQ5D. No que diz respeito à “Satisfação em relação à vida estudantil”: há correlação negativa com o score SF e correlação positiva com o score EQ5D. Em relação a “satisfação em relação a atividades sociais extra-curriculares”: há correlação negativa com o score SF e correlação positiva com o score EQ5D. Como o valor da correlação é de 1, dizemos que essa correlação é muito forte. Relativamente a “Preocupação quanto ao futuro”, há correlação positiva com o score SF e correlação negativa com o score EQ5D.Discussão e Conclusão: Ainda que uma das questões do SF-8 não tenha sido aplicada neste estudo, podemos concluir que o score SF e o Eq-5D estão fortemente correlacionados de forma inversa. Os 3 anos de curso estudados têm a mesma distribuição de respostas para ambos os scores EQ5D e SF. Concluímos também que a distribuição de SF e EQ5D é semelhante para os 2 sexos (ver tabela 3). Ainda assim, podemos dizer que, na nossa amostra, o valor médio para o score EQ5D é de 0,812 para o sexo masculino e de 0,726 para o sexo feminino, o que indica que os rapazes estudantes de medicina têm qualidade de vida superior e as raparigas deste curso têm qualidade de vida inferior à população portuguesa em geral. O “estado de saúde neste momento” correlaciona-se de forma positiva moderada em relação ao EQ-5D, o único questionário utilizado em pleno neste estudo; a “satisfação em relação à vida estudantil” apresenta correlação positiva fraca; a “satisfação em relação a atividades sociais extra-curriculares” tem correlação positiva muito forte e a “Preocupação quanto ao futuro” apresenta correlação negativa fraca.
Background: Teaching in medical schools demands from the students full-time dedication, which sometimes leads to a compromise in the physical and social well-being of these students. The present study uses the EQ-5D and SF-8 questionnaires to evaluate the quality of life of medical students of the University of Coimbra in the clinical years (4th, 5th and 6th years) during the 2016/2017 school year.Objectives: To evaluate the quality of life of the students in the clinical cycle of FMUC (4th to 6th grade) and to understand the correlation between EQ5D-3L and SF-8 as a function of the epidemiological variables age, sex, extra-curricular social, satisfaction with student and social life as well as concern for the future.Methodology: An observational study was carried out with an analytical intention, in a convenience sample, but representative of the students population of the 4th, 5th and 6th years of the Medicine course of the Faculty of Medicine of the University of Coimbra, in the academic year 2016/2017. A questionnaire was developed based on the issues of EQ-5D and SF-8, which was applied through the "Google Forms" platform. The data were submitted to descriptive and statistical analysis, using the Kruskal-Wallis, Mann-Witney and ANOVA tests and the Pearson and Spearman correlations.Results: The 105 students of the 3 years studied and both sexes have the same distribution of answers for the SF and Eq5D Scores. There are no statistically significant differences between these scores relative to the type of residence in class time. Both scores correlate inversely. As for "health status at this time": there is negative correlation with the SF score and positive correlation with the EQ5D score. Regarding "Satisfaction in relation to student life": there is negative correlation with the SF score and positive correlation with the EQ5D score. Regarding "satisfaction with extra-curricular social activities": there is a negative correlation with the SF score and a positive correlation with the EQ5D score. Since the value of the correlation is 1, we say that this correlation is very strong. Concerning "Concern about the future", there is a positive correlation with the SF score and negative correlation with the EQ5D score.Discussion: Although one of the questions of the SF-8 has not been applied in this study, we can conclude that the SF score and the Eq-5D are strongly correlated inversely. The 3 year course studied has the same distribution of answers for both EQ5D and SF scores.We also conclude that the distribution of SF and EQ5D is similar for both sexes (see table 3). Still, we can say that in our sample the mean value for the EQ5D score is 0.812 for the male sex and 0.726 for the female sex, which indicates that the medical students boys have higher quality of life and the girls of this course have lower quality of life than the Portuguese population in general.The "state of health at this time" correlates in a moderately positive way with respect to the EQ-5D, the only questionnaire used in full in this study; "satisfaction with student life" has a weak positive correlation; the "satisfaction with extra-curricular social activities" has a very strong positive correlation and "Concern about the future" presents a weak negative correlation.

Abstract:
Social comparison influences well-being, especially during psychological threat. Social comparison outcomes have been theorized to depend on motivation, frequency, contrast versus identification, with a better- versus worse-off other. To reduce this complexity in the theory, 94 senior-housing residents were interviewed and cluster analysis was conducted. Four clusters emerged. Half the interviewees formed a cluster using only adaptive social comparison methods. Adaptives were contrasted with a cluster of indiscriminate comparers, a cluster striving for improvement, and a cluster of participants disagreeing with most questions. Clusters differed especially in patterns of downward identification, upward and downward contrast. Self-evaluation and uncertainty-reduction also differed between clusters; self-enhancement and self-improvement motivations did not. Cluster membership had no direct effect on well-being, but moderation analysis demonstrated threat-buffering of high neuroticism in the adaptive cluster. The benefits were not due to self-esteem or educational level. By separating individuals rather than behaviors, cluster analysis provides a fresh perspective.

Abstract:
The history of science fiction (SF) in the movies is reviewed in depth. At this point in the Big Moon Dig story series, an artificial intelligence (AI) is needed placed in the new settlement on the Moon. Designing electronics for operation in space is difficult and two major AIs on Earth support this design effort. The question of whether or not the Earth-bound AIs can be considered the parents of the space-based AI is a key point of discussion. The story in this chapter, “Caterpillars on the Moon,” features the landing of an inflatable habitat section on the Moon and its movement, caterpillar fashion, into position.

Abstract:
The use of gait assistive devices, although can provide precious help can also have limitations or adverse consequences. The performance of daily activities is partially restrained by a series of factors having to do with the assistive device limitations or the limitations emerged from environmental causes. Valid and reliable assessment tools to classify and clarify their limitations or users' satisfaction do not exist. An extended literature search was performed for some of the most commonly mentioned assistive device limitations or dissatisfaction reasons and identified the most appropriate tools to be able to study such limitations and conclude in valid outcomes. A study was conducted in a rehabilitation hospital using the IPA, EQ5D and SF-12 tools. The size of the sample combined with the uncertainty related to the satisfaction of normal distribution prerequisite, led to use several statistical analysis tools and methodologies. A summary of the results from both the literature review and the real case study on a mixed group of mobility aid users are presented in the paper.

Abstract:
Silica fume (SF) is used as a constituent to formulate cementitious materials for subsurface (oil-well) applications, e.g. by the offshore industry. Using green supplementary pozzolanic materials like silica fume could both improve the material’s performance and the footprint of the sustainable solution. X-ray diffraction and isothermal calorimetry were employed to investigate the evolution of cement paste hydration (water to binder ratio 0.44) after 14 h, 3, 7, and 28 days of curing. Experimental results are presented for both cement pastes made of Class G Portland cement and for a blended paste system where 8% of the Class G cement has been replaced by silica fume. The results indicate beneficial effects of SF on the microstructural development of the slurry.

Full text
Abstract:
A low decay heat (implying Spent Fuel (SF) pebbles older than 8–9 years) bulk dry storage section is proposed to supplement a 12-tank wet storage section. Decay heat removal by passive means must be guaranteed, taking into account the fact that dry storage vessels are under ground and inside the building footprint. Cooling takes place when ambient air (drawn downwards from ground level) passes on the outside of the 6 tanks’ vessel containment (and gamma shielding), which is in a separate room inside the building, but outside PBMR building confinement and open to atmosphere. Access for loading / unloading of SF pebbles is only from the top of a tank, which is inside PBMR building confinement. No radioactive substances can therefore leak into atmosphere, as vessel design will take into account corrosion allowance. In this paper, it is shown (using CFD (Computational Fluid Dynamics) modelling and analytical analyses) that natural convection and draught induced flow combine to remove decay heat in a self-sustaining process. Decay heat is the energy source, which powers the draught inducing capability of the dry storage modular cell system: the more decay heat, the bigger the drive to expel heated air through a higher outlet and entrain cool ambient air from ground level to the bottom of the modular cell.

Abstract:
Load tests were conducted on pretensioned members made with five different strands (three 7-wire strands and two 3-wire strands) to determine the effect of concrete release strength on the development length and flexural capacity of members. Strands named generically SA, SC, SD, SE and SF and they were all indented except SA (no surface indentation). All strands had diameter of 3/8″ (9.52 mm) except SC which had diameter of 5/16″ (7.94 mm). Among all types of strands used in manufacturing of test prisms, SC and SF were 3-wire strands, while SA, SD and SE were 7-wire strands. A consistent concrete mixture was used for the manufacture of all test specimens, and the different release strengths were obtained by allowing the specimens to cure for different amounts of time prior to de-tensioning. For SA, SD, SE and SF strands, each prismatic specimen (prism) had a 5.5″ (139.7 mm) × 5.5″ (139.7 mm) square cross section with four strands arranged symmetrically. However, prisms made with SC strand had 4.5″ (114.3 mm) × 4.5″ (114.3 mm) square cross section with four strands arranged symmetrically. The prisms were identical except for the strand type and the compressive strength at the time of de-tensioning. All four strands were pulled and de-tensioned gradually when the concrete compressive strength reached 3500 (24.13 MPa), 4500 (31.03 MPa) and 6000 (41.37 MPa) psi. Precise de-tensioning strengths were ensured by testing 4-in.-diameter (101.6 mm) × 8-in.-long (203.2 mm) compression strength cylinders that were temperature match-cured. The prisms were loaded in 3-point-bending to determine the ultimate bond characteristics of each reinforcement type for the different concrete release strengths. A loading rate of 900 lb/min (4003 N/min) for 5.5″ (139.7 mm) × 5.5″ (139.7 mm) prisms was applied at mid-span and the maximum sustained moment was calculated for each. Same procedure with loading rate of 500 lb/min (2224 N/min) was applied to 4.5″ (114.3 mm) × 4.5″ (114.3 mm) prisms. Three 69-in.-long (175.26 cm) prisms, each having different concrete release strength, were tested with each of the 5 strand types. Two out of three testing prisms were tested at only one end and one was tested at its both ends. Thus, for each strand type and concrete release strength evaluated, a total of 4 tests were conducted for a total of 60 tests (5 strand types × 3 release strengths × 4 tested embedment lengths). Test results indicate that the concrete compressive strength at de-tensioning can have a direct impact on the ultimate flexural capacity of the members, and this has significant design implications for pretensioned concrete railroad ties. Results are discussed and recommendations made.

Abstract:
The effect of using Portland cement, nano silica (NS) and /or micro silica on the mechanical and physical properties of concretes containing fine aggregate only is investigated. Two groups divided into five series each have been designed and tested. The first group was containing the nano-silica only, while the second group contained different ratios of nano silica and a constant content of 8 % of silica fume (SF) (by weight) as partial replacement of cement. Water cementations ratio (w/c) of all mixtures was constant and equal to 0.22. The cement content in all series was 800 kg/m3. Commercially available nano silica (NS) was used in the mixture for the partial substitution of cement at ratios of 0, 0.5, 1.0, 2 and 3% by weight. It was found that the addition of nano –silica is significantly enhance compressive, tensile and modulus of elasticity of concrete. From the test results obtained it has been noted that the mix containing 2 % possess significantly improved mechanical properties, furthermore, the group samples of concrete containing binary cementations nano-silica and silica fume showed better results than concrete containing nano silica only.

Abstract:
Pretensioned concrete prisms made with five different prestressing strand types (four 7-wire strands and one 3-wire strand) were load tested to failure to understand the effect of strand indentation types on the development length and bonding performance of these different reinforcements. The prestressing strands were denoted SA, SB, SD, SE and SF. SA was a smooth strand while the other four were indented strands. All strands utilized in manufacturing ofprisms had diameter of 3/8″ (9.52 mm). Among all types of strands, SF was the only 3-wire strand and the remaining strands were all 7-wire strands. For all types of strands, four straight strands were embedded into each concrete prism, which had a 5.5″ (139.7 mm) × 5.5″ (139.7 mm) square cross section. The strands were tensioned to 75 percent of ultimate tensile strength of strands and gradually de-tensioned when the concrete compressive strength reached 4500 psi (31.03 Mpa). A consistent concrete mixture with type III cement, water-cement ratio of 0.32 and a 6-in. slump was used for all prisms. Prisms were load tested in 3-point-bending at different embedment lengths to obtain estimations of the development length of each type of strand. Two out of three identical 69-in.-long (175.26 cm) prisms were load tested at one end and one was tested at both ends for each reinforcement type evaluated. First prisms were tested at 28-in. (71.12 cm) from the end, while second prisms were tested at 20-in. (33.02 cm) from the end. Third prisms were loaded at 16.5-in. (41.9 cm) from one end and 13-in. (33.02 cm) from the other end. Thus, a total of 20 load tests (5 strand types × 4 tests each) were conducted in this study. During each test, a concentrated load with the rate of 900 lb/min (4003 N/min) was applied at mid-span until failure occurred. Values of load, mid-span deflection, and strand endslip were continuously monitored and recorded during each test. Plots of load-vs-deflection were then compared for prisms with each strand type and span, and the maximum sustained moment was also calculated for each test. The load tests revealed that there is a large difference in the development length of the strands based on their indentation type.

Abstract:
Industry-specific technology demonstration projects are key to facilitating deployment of solar industrial process heat technologies. Frito Lay North America (FLNA) is pursuing installation of a solar industrial process heat plant at the manufacturing plant in Modesto CA. FLNA contracted with Industrial Solar Technology Corp. for design and installation of the system and with National Renewable Energy Lab for technical assistance. The US Department of Energy and California Energy Commission both facilitate private companies implementation of technology demonstration projects with incentives, tax policy, and technical assistance. The solar plant would include: 5,387 m2 (57,969 sf) of parabolic trough solar collectors; pipe from solar array to unfired steam generator; unfired steam generator (USG); hot water heat exchanger (HWHX); pipe from hot water heat exchanger back to array field; and associated pumps, bypass piping, and controls. Performance of each component of the solar heating system varies with changing conditions of intensity of the sunlight, position of the sun, and ambient temperature. Since each of these parameters change throughout the day and throughout the seasons an hourly simulation of one year’s performance is performed. The simulation is used to estimate annual energy delivery as well as to inform design recommendations. The solar array inlet temperature is solved for iteratively for each hour of the year based on an energy balance of the entire loop including all components. Nested within this iteration are iterations for the operating temperature of each of the 16 modules in series. Hourly direct beam solar radiation (W/m2) data for Modesto CA for 8 years from 1998–2005 was provided by the National Renewable Energy Laboratory Renewable Resource Data Center and the minimum year, average year, and maximum year were used in the analysis. Results indicate that the system would deliver between 3,898 MWh and 4,308 MWh per year (13.3 and 14.7 billion Btu/year) with an average of 4,044 MWh/year (13.8 billion Btu/year). This average estimate of 13.8 billion Btu/year agrees with the contractors proposal and also with methods described in the Industrial Process Heat Handbook published by NREL. The simulation is able to model more detail and inform design recommendations, such as bypassing the steam generator and only making hot water on winter days.
