Space Station Freedom Solar Array design development

The Space Station Freedom Solar Array Program is required to provide a 75 kW power module that uses eight solar array (SA) wings over a four-year period in low Earth orbit (LEO). Each wing will be capable of providing 23.4 kW at the 4-year design point. Lockheed Missles and Space Company, Inc. (LMSC) is providing the flexible substrate SAs that must survive exposure to the space environment, including atomic oxygen, for an operating life of fifteen years. Trade studies and development testing, important for evolving any design to maturity, are presently underway at LMSC on the flexible solar array. The trade study and development areas being investigated include solar cell module size, solar cell weld pads, panel stiffener frames, materials inherently resistant to atomic oxygen, and weight reduction design alternatives

Resettled: A Portrait of Bhutanese Refugees in Dayton, Ohio

75 Bhutanese refugees have been resettled in Dayton, Ohio. Through an intensive case study with one Bhutanese refugee family and interviews with local refugee service providers the topics of English language acquisition, issues surrounding the job search and religion as both a community builder and insulator are examined

Urban Wind Generation: Comparing Horizontal and Vertical Axis Wind Turbines at Clark University in Worcester, Massachusetts

Electricity production must shift towards carbon neutral sources such as wind power to mitigate the impacts of climate change. The wind resource in urban environments is challenging to predict but technologies, including computational fluid dynamics software, are making it possible. This software pinpoints suitable placement for wind turbines through models that show wind acceleration patterns over a building. Horizontal axis wind turbines (HAWTs) have dominated the wind industry but vertical axis wind turbines (VAWTs) offer potential to outperform HAWTs in urban environments. VAWTs can handle turbulent and unconventional wind and generate energy at slower speeds, which is beneficial for these areas. A case study at Clark University in Worcester, Massachusetts analyzes the functionality of a HAWT and a VAWT. The machines are compared by their efficiencies due to an imbalance of rated power outputs. The machines’ average maximum power coefficients are similar. However, when the R2 values of the turbine’s power curves are compared the VAWT demonstrates greater capacity to track changes in the wind. This research is the first step in redefining the power systems employed at Clark University and the data will be utilized to find better locations for the wind turbines

The Effect of Conjugated Linoleic Acid (CLA) on Feed Efficiency and Carcass Composition in Barrows

The purpose of this study was to determine if conjugated linoleic acid (CLA) would have an effect on feeding efficiency and carcass composition of 20 finishing barrows obtained from the West Virginia University Animal Science Farm. A posttest experimental design was used to obtain data for the study. The barrows were matched for weight and placed two in a pen. The pens were randomly assigned to a diet consisting of either a 1% CLA oil or 1% soybean oil. The six week study found that weight gain, average daily feed intake, muscle lipids, loin eye area, and color were not affected by CLA. In week five average daily gain for the control group was significantly higher than the CLA group. In weeks one and five the gain to feed ratio was significantly greater for the control group. Subjective marbling scores were higher for the CLA group but not of significant value. Backfat decreased significantly in the CLA group compared to the control group. In conclusion, the use of CLA can create a leaner product with the possibility of increased marbling

Associations of active transportation between childhood and adulthood (CADET)

Master of Public HealthDepartment of KinesiologyGina BesenyiInsufficient physical activity (PA) is a growing issue throughout the world. Diabetes, chronic heart disease, and shortened life expectancy are among the comorbidities resulting from insufficient PA. Studies on the development of PA behaviors have highlighted parental and environmental influences as contributors that persist across the lifespan. Active transportation (AT) is one possible avenue for PA promotion. AT is any movement from place to place without the use of a motor for occupational, utilitarian and recreational trips. The purpose of this study was to examine factors of AT development across the lifespan, including parental influence variables, which included parental support and role-modeling for AT and neighborhood environment quality associations with child AT, as well as the associations between child AT and adult AT. Positive associations were hypothesized between the following variables: parental support and child AT, parental role-modeling and child AT, child neighborhood environment and child AT, as well as child AT and adult AT. The cross-sectional survey was completed by participants (n = 98, predominately college-educated (93%), young (avg: 26±9.9 years), white (84%), females (72%) by providing recall data on their childhood (<18 years) AT behaviors, frequencies and destinations, as well as parental and environmental influences on AT. Respondents reported their current AT behaviors, frequencies and destinations, their current moderate-to-vigorous PA, and demographic information. The association between parental influence and child biking was significant (OR = 0.13, P = 0.02, 95% C.I. = 0.02, 0.75), as well as the associations between child walking and adult walking (OR = 17.61, p = 0.01, 95% C.I. = 2.01, 154.05) child biking and adult biking (OR = 11.75, p = 0.001, 95% C.I. = 2.38, 58.07), and child public transportation and adult transportation (OR = 6.92, p = 0.01, 95% C.I. = 1.79, 26.82). Findings suggested a more complex relationship between parental support behaviors and child AT than initially hypothesized and supported the hypothesized association between child AT and adult AT. The association of child AT behavior with adult AT behavior in specific AT sub-modes (walking, biking and public transportation) were supported
