The space shuttle launch vehicle aerodynamic verification challenges

The Space Shuttle aerodynamics and performance communities were challenged to verify the Space Shuttle vehicle (SSV) aerodynamics and system performance by flight measurements. Historically, launch vehicle flight test programs which faced these same challenges were unmanned instrumented flights of simple aerodynamically shaped vehicles. However, the manned SSV flight test program made these challenges more complex because of the unique aerodynamic configuration powered by the first man-rated solid rocket boosters (SRB). The analyses of flight data did not verify the aerodynamics or performance preflight predictions of the first flight of the Space Transportation System (STS-1). However, these analyses have defined the SSV aerodynamics and verified system performance. The aerodynamics community also was challenged to understand the discrepancy between the wind tunnel and flight defined aerodynamics. The preflight analysis challenges, the aerodynamic extraction challenges, and the postflight analyses challenges which led to the SSV system performance verification and which will lead to the verification of the operational ascent aerodynamics data base are presented

Sioux Falls Renewable Project Final Report

Sioux Falls is the largest city in South Dakota with a population of over 171,000 residents. Sioux Falls is one of only two cities in South Dakota to have an Office of Sustainability. South Dakota is a national leader in the amount of renewable energy produced with large amounts of hydropower and wind energy produced, and the climactic conditions on South Dakota are conducive for additional wind and solar energy production. Therefore, Sioux Falls is well position to take a leadership role in mitigating climate change in South Dakota. One way for Sioux Falls to mitigate climate change – and model climate action for the state and region – is to transition the energy use in the city to 100% renewable energy. There are currently more than 175 cities in the United States that have completed, are in the process, or have pledged to transition to 100% renewable energy. Although Sioux Falls is not one of these cities, we believe that there is potential for Sioux Falls to transition to 100% renewable energy. The primary uses of energy in a city include electricity, heating, and transportation. Based on reviews of the existing cities who are or have transitioned to 100% renewable energy, we determined that many cities first focus on a transition to 100% renewable electricity. The purpose of this report is to explore the opportunities and constraints – and to provide recommendations – for engaged stakeholders to develop a campaign for Sioux Falls to transition to 100% renewable electricity by 2035.https://red.library.usd.edu/sustainability-projects/1006/thumbnail.jp

Adaptation of a Community Health Advisor Intervention to Increase Colorectal Cancer Screening Among African Americans in the Southern United States

Community health advisor (CHA) interventions increase colorectal cancer (CRC) screening rates. Focus groups and learner verification were used to adapt National Cancer Institute CRC screening educational materials for delivery by a CHA to African American community health center patients. Such academic-community collaboration improves adoption of evidence-based interventions. This short article describes the adaptation of an evidence-based cancer education intervention for implementation in an African American community

Asymmetries in L2 functional morphology: The Korean learner of English

Variability in the production of L2 functional morphology has long been recognised as a pervasive and entrenched characteristic of interlanguage development. As Trenkic (2007, p. 292) suggests, a potentially fruitful way of identifying the sources of this behaviour is to compare the rates at which a given morpheme (e.g., past tense) is omitted, substituted or oversupplied in two (or more) distinct contexts. The present thesis adds to earlier work exploring certain patterns of this type, while also seeking to address some of the main limitations of these studies. Using a combined elicited-imitation and story-recall task adapted from Snape (2006), I examine the production of various types of functional morpheme by Korean learners of English. Three experiments were conducted. In the first of these, I predicted asymmetries in the omission or substitution of definite articles in first- and second-mention DPs based on the effects of non-target form-meaning relationships plus communicative redundancy. The second experiment examined past tense, agreement and plural morphology, and investigated the claim that differences in stem length and (for tense inflection only) verb class would give rise to contrasting patterns of inflectional omission. The third experiment focused on various kinds of QP, and manipulated the effects of contrasts in quantifier type and syntactic structure on the omission of plural inflection in these phrases. The predictions of experiment 1 were not supported, while those of experiment 2 were not supported for tense inflection; however, I am able to suggest reasons for these unexpected results. The overall results of the thesis confirm that by systematically investigating asymmetries in the production of a given functional morpheme, we stand to gain an insight into the underlying causes of L2 variability

Adolescent Experiences with Self-Asphyxial Behaviors and Problematic Drinking in Emerging Adulthood

Self-asphyxial behavior to achieve a euphoric high (The Choking Game; TCG), occurs most often during early adolescence. Participants in TCG often engage in other risky behaviors. This study investigated the relationship between prior experience with TCG and problematic drinking behaviors in emerging adulthood. Emerging adults, 18 to 25 years old (N = 1248), 56% female, and 78% Caucasian completed an online survey regarding knowledge of and prior engagement in TCG and current drinking behaviors. Participants who personally engaged in TCG during childhood/adolescence or were familiar with TCG reported significantly more problematic drinking behaviors during emerging adulthood. Those present when others engaged in TCG but resisted participation themselves reported significantly less current problematic drinking behaviors than those who participated, but significantly more current problematic drinking behaviors than those never present. Emerging adults with increased social familiarity with TCG during adolescence endorsed greater problematic drinking behaviors. Results suggest resistance skills may generalize across time/activities

Exploratory randomized double-blind placebo controlled trial of botulinum therapy on grasp release after Stroke (PrOMBiS)

Background. OnabotulinumtoxinA injections improve upper-limb spasticity after stroke, but their effect on arm function remains uncertain. Objective. To determine whether a single treatment with onabotulinumtoxinA injections combined with upper-limb physiotherapy improves grasp release compared with physiotherapy alone after stroke. Methods. A total of 28 patients, at least 1 month poststroke, were randomized to receive either onabotulinumtoxinA or placebo injections to the affected upper limb followed by standardized upper-limb physiotherapy (10 sessions over 4 weeks). The primary outcome was time to release grasp during a functionally relevant standardized task. Secondary outcomes included measures of wrist and finger spasticity and strength using a customized servomotor, clinical assessments of stiffness (modified Ashworth Scale), arm function (Action Research Arm Test [ARAT], Nine Hole Peg Test), arm use (Arm Measure of Activity), Goal Attainment Scale, and quality of life (EQ5D). Results. There was no significant difference between treatment groups in grasp release time 5 weeks post injection (placebo median = 3.0 s, treatment median = 2.0 s; t(24) = 1.20; P = .24; treatment effect = −0.44, 95% CI = −1.19 to 0.31). None of the secondary measures passed significance after correcting for multiple comparisons. Both groups achieved their treatment goals (placebo = 65%; treatment = 71%), and made improvements on the ARAT (placebo +3, treatment +5) and in active wrist extension (placebo +9°, treatment +11°). Conclusions. In this group of stroke patients with mild to moderate spastic hemiparesis, a single treatment with onabotulinumtoxinA did not augment the improvements seen in grasp release time after a standardized upper-limb physiotherapy program

Wireless aquatic navigator for detection and analysis (WANDA)

The cost of monitoring and detecting pollutants in natural waters is of major concern. Current and forthcoming bodies of legislation will continue to drive demand for spatial and selective monitoring of our environment, as the focus increasingly moves towards effective enforcement of legislation through detection of events, and unambiguous identification of perpetrators. However, these monitoring demands are not being met due to the infrastructure and maintenance costs of conventional sensing models. Advanced autonomous platforms capable of performing complex analytical measurements at remote locations still require individual power, wireless communication, processor and electronic transducer units, along with regular maintenance visits. Hence the cost base for these systems is prohibitively high, and the spatial density and frequency of measurements are insufficient to meet requirements. In this paper we present a more cost effective approach for water quality monitoring using a low cost mobile sensing/communications platform together with very low cost stand-alone ‘satellite’ indicator stations that have an integrated colorimetric sensing material. The mobile platform is equipped with a wireless video camera that is used to interrogate each station to harvest information about the water quality. In simulation experiments, the first cycle of measurements is carried out to identify a ‘normal’ condition followed by a second cycle during which the platform successfully detected and communicated the presence of a chemical contaminant that had been localised at one of the satellite stations
