Prototyping a Well-Driver PUP (Purdue Utility Project) to Install Low-Cost Driven Water Wells
Creators: name: Horn, Zackariah J
Publisher: name: Purdue University Graduate School
Year: 2019
Subjects: Agricultural engineering

description: People living in developing countries or undeveloped regions often do not have proper access to quantities of safe, clean water to fulfill their daily needs. Certain members of the families, often women and children, walk miles every day to collect surface waters that are frequently contaminated. To improve water availability and quality, a sustainable mechanical solution to more safely access groundwater has been developed. A well-driving attachment for a PUP (Purdue Utility Project) vehicle provides a low-cost means for installing driven type wells in areas of high to medium water table heights. PUP vehicles have a niche in developing countries, as they offer impressive value and utility in comparison to other powered machines. The vehicles are built and sourced using locally available materials with basic tooling. A hydraulic post driver has been attached to the rear of a PUP frame to serve as an impact mechanism, driving a well point and a series of inter-connecting pipes to serve as a permanent casing for the well. Water wells were tested at four different test sites around central Indiana, with the deepest well reaching 23 feet. This suggests that the Well-Driver PUP can install driven water wells in areas of medium to high water tables and may be suitable for a development setting. Water wells can be installed on a communal basis, thus providing an increased level of hygiene and standards of living. Low-cost driven water wells will provide a drinking water supply that is better protected than a hand-dug well and will reduce the likelihood of disease caused by waterborne pathogens. Development of the Well-Driver PUP prototype and its applications will be discussed.

description: Augmented reality (AR) allows people to view digital information overlaid on to real-world objects. While the technology is still new, it is currently being used in places such as the military and industrial assembly operations in the form of ocular devices worn on the head over the eyes. Head-mounted displays (HMDs) let people always see AR information in their field of view no matter where their head is positioned. Studies have shown that HMDs displaying information directly related to the immediate task can decreased cognitive workload and increase the speed and accuracy of task performance. However, task-irrelevant information has shown to decrease performance and accuracy of the primary task and also hinder the efficiency of processing the irrelevant information. This has been investigated in industry settings but less so in an everyday consumer context. This study proposes comparing two types of visual information (text and shapes) in AR displayed on an HMD to answer the following questions: 1) when content is of importance, which visual notification (text or shapes) is processed faster while degrading the performance of the primary task the least? And 2) When presence is of importance, which visual notification (text or shapes) is processed faster while degrading the performance of the primary task the least?

description: Background: Guidelines in several European countries recommend standby emergency treatment (SBET) for travellers to regions with low or medium malaria transmission instead of continuous chemoprophylaxis: travellers are advised to seek medical assistance within 24 h in case of fever and to self-administer SBET only if they are not able to consult a doctor within the time period specified. Data on healthcare-seeking behaviour of febrile travellers and utilization of SBET is however scarce as only two studies were performed in the mid-1990s. Since tourism is constantly increasing and malaria epidemiology has dramatically changed in the meantime more knowledge is urgently needed. Methods: Some 876 travellers to destinations in South and Southeast Asia with low or medium malaria transmission were recruited in the travel clinic of the University Medical Center Hamburg-Eppendorf. Demographic and travel-related data were collected by using questionnaires. Pre-travel advice was carried out and SBET was prescribed in accordance to national guidelines. Post-travel phone interviews were performed to assess health incidents during travel and individual responses of travellers to febrile illness. Results: Out of 714 patients who were monitored, 130 (18%) reported onset of fever during travel or 14 days after return. Of those travellers who reported fever, 100 (80%) carried SBET during travel. The vast majority of 79 (79%) febrile travellers who carried SBET did not seek medical assistance. Overall, 14 (14%) febrile patients who carried SBET and six (20%) patients who did not carry SBET took the correct measure (doctor visit or timely SBET administration) as a response to febrile illness, respectively. Only two travellers self-administered SBET, but both of them applied the wrong regimen. Conclusions: In view of declining malaria transmission and improving medical infrastructure in most countries of Southeast Asia and obvious obstacles concerning SBET as shown in this study the current strategy should be re-evaluated. Pre-travel advice concerning malaria in SEA should focus on appropriate mosquito bite protection and clearly emphasize the need to see a doctor within 24 h after onset of fever.

description: This was a presentation of my conference paper "A Suitable Design: Analyzing The English Style Guide Genre." Due to the COVID-19 pandemic, all presentations were to be previously filmed then screened on Zoom.

Paper Abstract:

This paper will examine how the genre conventions of English style guides contribute to their public success to this day. My argument is that the genre conventions of English style guides have sociological and psychological effects on readers. To support my argument, I will be doing a genre analysis on one text that has been considered a staple of the genre: The Elements of Style by William Strunk Jr. and E. B. White. This paper will comprise three sections: first, a literature review will present what has been previously written on the genre and its history. Second, I will be using Stephen Bax's model of genre analysis to answer the three main questions of "what," "why," and "how" in relation to The Elements of Style. For the "what" question, I will utilize personal interviews from two people who write, teach writing, and use English style guides daily—one a copyeditor, one a school teacher. These interviews will help contextualize how English style guides like The Elements of Style are applied in the real world. For the "why" question, I will explore the sociological implications of teaching writing and the reasons why The Elements of Style even needs to exist. For the final section of this paper, I will analyze the following key linguistic features found in The Elements of Style as per the "how" question in Bax's model: authoritative tone, contextual examples, and interlinked content. Ultimately, I will reach a conclusion on why English style guides have remained a popular and reliable way to learn writing style and grammar.

description: Background: An increasing rate of respiratory colonization and infection in cystic fibrosis (CF) is caused by fungi of the Scedosporium apiospermum species complex or Lomentospora prolificans (Sac-Lp). These fungi rank second among the filamentous fungi colonizing the CF airways, after Aspergillus fumigatus. However, the epidemiology, clinical relevance and risk of pulmonary colonization with Sac-Lp are rarely understood in CF. The objective of the present prospective multicenter study was to study pathogen distribution and determine association factors of pulmonary Sac-Lp colonization in patients with CF. Material and methods: Clinical, microbiological and laboratory data of 161 patients aged 6–59 years with CF in Germany were analyzed for Sac-Lp distribution and association factors. The free statistical software R was utilized to investigate adjusted logistic regression models for association factors. Results: Of the 161 patients included in the study, 74 (56%) were male. The median age of the study cohort was 23 years (interquartile range 13–32 years). 58 patients of the total cohort (36%) were < 18 years old. Adjusted multivariate regression analysis revealed that Sac-Lp colonization was associated with younger age (OR 0.8684, 95%CI: 0.7955–0.9480, p

description: Der demografische Wandel, neue Gesundheitsbedrohungen, gesundheitliche und Versorgungsungleichheiten in und zwischen Staaten der Europäischen Union (EU) stellen die Gesundheitssysteme in Europa vor große Herausforderungen. Viele Gründe sprechen dafür, vergleichbare Gesundheitsdaten in Europa zu erheben: Sie geben Aufschluss über die Verteilung von Risiko- und Schutzfaktoren, Prävalenzen chronischer Erkrankungen und die Versorgungssituation in den Mitgliedstaaten und unterstützen dadurch die Planung und Umsetzung (gesundheits-) politischer Maßnahmen. Seit 2013 erheben alle EU-Mitgliedstaaten verpflichtend im Rahmen der Europäischen Gesundheitsumfrage (European Health Interview Survey, EHIS) Daten zum Gesundheitszustand, zur gesundheitlichen Versorgung, den Gesundheitsdeterminanten und zur sozioökonomischen Lage ihrer Bürgerinnen und Bürger. In Deutschland ist der EHIS Teil des Gesundheitsmonitorings des Robert Koch-Instituts (RKI). Das RKI bildet damit die Schnittstelle Deutschlands zu dem hier vorgestellten europäischen Gesundheitsmonitoring. Unterschiedliche Indikatorensysteme stützen das europäische Gesundheitsmonitoring. Zu ihnen zählen die Europäischen Kernindikatoren für Gesundheit (European Core Health Indicators, ECHI), die EU-Sozialindikatoren und die gesundheitsrelevanten Indikatoren der Europäischen Nachhaltigkeitsstrategie. Gespeist werden sie aus Routine- und Befragungsdaten, u.a. dem EHIS oder der EU-Umfrage zu Einkommen und Lebensbedingungen (EU-SILC). Unterschiedliche Gesundheitssysteme, sozioökonomische Lagen oder Altersstrukturen müssen bei vergleichenden Auswertungen dieser Daten berücksichtigt werden. So sind Prävalenzunterschiede bei Allergien unter anderem auf die verfügbaren diagnostischen Maßnahmen zurückzuführen. Große Prävalenzunterschiede des Bluthochdrucks in Europa (20 Prozentpunkte bei Frauen, 17 Prozentpunkte bei Männern) hängen u.a. mit dem Bekanntheitsgrad der Hypertonie zusammen. Die Ergebnisse vergleichender Auswertungen können der Planung politischer Maßnahmen sowie dem Erfahrungsaustausch zwischen EU-Staaten dienen. Über eine neue geplante EU-Verordnung sollen zukünftig Gesundheits- und sozialstatistische Erhebungen inhaltlich und zeitlich stärker aufeinander abgestimmt werden. Darüber hinaus soll ein Forschungskonsortium (European Research Infrastructure Consortium, ERIC) geschaffen werden, um das europäische Gesundheitsmonitoring auszubauen und zu verstetigen.

Simulating Scramjet Behavior: Unstart Prediction in a Supersonic, Turbulent Inlet-Isolator Duct Flow
Creators: name: Hall, Ian Avalon
Publisher: name: Purdue University Graduate School
Year: 2019
Subjects: Aerospace engineering not elsewhere classified

description: In the pursuit of developing hypersonic cruise vehicles, unstart is a major roadblock to achieving stable flight. Unstart occurs when a sudden instability in the combustor of a vehicle’s propulsion system creates an instantaneous pressure rise that initiates a shock. This shock travels upstream out of the inlet of the vehicle, until it is ejected from the inlet and creates a standing shockwave that chokes the flow entering the vehicle, thereby greatly reducing its propulsive capability. In severe cases, this can lead to the loss of the vehicle. This thesis presents the results of a computational study of the dynamics of unstart near Mach 5 and presents some possible precursor signals that may indicate its presence in flight. Using SU2, an open-source CFD code developed at Stanford University, the Unsteady Reynolds-Averaged Navier-Stokes equations are used to develop a model for flow in a scramjet inlet-isolator geometry, both in the fully started state and during unstart. The results of these calculations were compared against experimental data collected by J. Wagner, at the University of Texas, Austin. In the present computations, unstart was initiated through the use of an artificial body force, which mimicked a moveable flap used in the experiments. Once the results of the code were validated against these experiments, a selection of parametric studies were conducted to determine how the design of the inlet-isolator by Wagner affected the flow, and thus how generalizable the results can be. In addition, precursor signals indicative of unstart were identified for further study and examined in the different parametric studies. It was found that a thick boundary layer is conducive to a stronger precursor signal and a slower unstart. In addition, an aspect ratio closer to 1:1 promotes flow mixing and reduces the unstart speed and strength. Moreover, an aspect ratio in this range reduces the precursor signal strength but, if a thick boundary layer is present, will smear the signal out over a larger area, potentially making it easier to detect.

description: Consuming harmful amounts of alcohol is considered a contributing factor in over 200 diseases. Heavy episodic drinking is a particularly risky drinking pattern, with possible consequences such as acute alcohol intoxication, injuries and violence. GEDA 2014/2015-EHIS defines heavy episodic drinking as the consumption of six or more alcoholic beverages on one occasion at least once per month. 24.9% of women and 42.6% of men show this drinking pattern at least once per month. Regular heavy episodic drinking is most common among 18- to 29-yearolds. The prevalence of heavy episodic drinking among highly educated women (all age groups) and men (aged over 45) is lower than it is among those with lower levels of education. The prevention of harmful levels of alcohol consumption requires measures including social and environmental interventions as well as targeting the individual behaviour which are focused on young adults as well as the diverse drinking patterns seen among groups with different levels of education.

BEYOND THE CLIMATE SCIENCE WARS: ELITE FRAMING AND CLIMATE CHANGE POLICY CONFLICT

description: Stakeholders involved in debates around climate-energy policy shape public conversations through different “frames”: message units that strategically emphasize particular aspects of an issue while downplaying others. I investigate the presence of frames within climate change discourse and their political influence in the creation of climate-energy policies. Findings suggest that science frames may play a limited role when it comes to the development of actual climate policy at the state level, and importantly, that the strategic use of issue frames was able to level the playing field between environmental advocates and historically dominant industry actors. This work thus contributes to ongoing debates in the climate change framing literature by considering the “real world” of political communication coupled with an on-the-ground policy conflict.

description: Juan Carlos  buscó decididamente un modelo común mediterráneo que permitiera explicar que muchas de las características de los llamados tradicionalmente “arte visigodo” o “arte mozárabe” eran independientes de la instauración de la dinastía Omeya en al-Andalús y, de manera mucho más profunda, cómo esa importancia e influencia que se concede al arte omeya o a determinados monumentos de ese arte, en el caso de Hispania, era injustificada e innecesaria. Hay una tendencia entre los historiadores del arte medieval español a retrasar fechas y rasgos de monumentos hispanos para explicarlos por influencia oriental que un estudio más detenido desmiente. Este estudio tiene que tener también en cuenta las especiales circunstancias que se presentan en esos monumentos orientales. Para ello hace falta una experiencia directa, un conocimiento del terreno y una capacidad de relación de lo estudiado que en el caso de nuestro autor fueron excepcionales. Por ello conviene insistir desde estos tristes momentos en la necesidad de mantener esta línea de investigación.
Exploration of the Mirroring Hypothesis as an Early Design Phase Parameter
Creators: name: Dukes, Alexandra Marie
Publisher: name: Purdue University Graduate School
Year: 2019
Subjects: Aerospace engineering not elsewhere classified

description: The mirroring hypothesis states the organization architecture and the product architecture tend to “mirror” or mimic each other. There are two types of investigations into this phenomenon: descriptive and normative. Descriptive studies ask whether mirroring is present in an organization/product pair. Normative studies ask whether mirroring aﬀects the performance of an organization/product pair. Much of the mirroring hypothesis literature claims to observe mirroring or claims mirroring improves the performance of the product. While there is still work to be done in the descriptive and normative realms of mirroring hypothesis research, there is a distinct gap in research investigating mirroring in the design phase of products and whether it can be used as a strategy during that phase. This work aims to demonstrate that diﬀerently mirrored organization/product pairs working the same example problem produce diﬀerent design solutions. This demonstration leads into an investigation on where in the life cycle mirroring would be most useful as a design parameter when designing a product. The results of this thesis show that for this speciﬁc example problem, mirroring has an eﬀect on the design solutions, and given a Department of Defense acquisition life cycle, there are opportunities where mirroring could be advantageous to use as a design strategy. This work challenges others interested in the topic to not just ask why does mirroring occur in design, but how can it be used to make the design better.

description: In this study, I use critical discourse analysis to analyze how queer women are represented in 34 English-language children’s picture books distributed in contemporary U.S. markets. I consider how these books include and exclude particular types of queer women characters and incorporate or omit specific queer women experiences. I argue that, in children's picture books, many queer women identities are “othered” through the binary oppositions of (i) lesbianism and motherhood and (ii) lesbianism and being a woman of color. In addition, (invisible) lesbianism in these picture books is still presented as an “issue.” The binary opposition of lesbianism and motherhood is created by making lesbianism invisible in children’s picture books by emphasizing mothering through the prominence of caregiving activities, limiting queer physical intimacy, limiting queer verbal intimacy, utilizing naming practices based on motherhood labels, and directing homophobia disproportionately at queer characters without children. The binary opposition of lesbianism and being a WOC is created by primarily featuring white queer characters. (Invisible) Lesbianism is still presented as an issue by the representation of two-mom families/queer relationships as “incomplete,” “unnatural,” “special,” “just the same as non-queer families and relationships,” and homonormativity. Informed by these results, I offer (i) a toolkit to evaluate the representation of queer women characters in picture books and (ii) a creative response to the queer women representation gaps in children’s literature.
Investigating the Self-tracking Use for Mental Wellness of New Parents
Creators: name: Jo, Eunkyung
Publisher: name: Purdue University Graduate School

Subjects: Human-computer interaction

description: New parents often experience significant stress as they take on new roles and responsibilities. Personal informatics practices have increasingly gained attention as they support various aspects of wellness of individuals by providing data-driven self-insights. While several PI systems have been proposed to support mental wellness of individuals not only by providing self-knowledge but also by helping individuals deal with negative emotions, few studies investigated how parenting stress can be managed through PI practices. In this paper, I set out to investigate how new parents make use of flexible self-tracking practices in the context of stress management. The findings of this study indicate that flexible self-tracking practices enable individuals to develop self-knowledge as well as to better communicate with their spouses through data. Based on the findings, I discuss how the self-tracking experiences for the mental wellness of parents can be better designed and provide some considerations for future research and design for parenting stress management.

description: Syndromic panels for infectious disease have been suggested to be of value in point-of-care diagnostics for developing countries and for biodefense. To test the performance of isothermal recombinase polymerase amplification (RPA) assays, we developed a panel of 10 RPAs for biothreat agents. The panel included RPAs for Francisella tularensis, Yersinia pestis, Bacillus anthracis, variola virus, and reverse transcriptase RPA (RT-RPA) assays for Rift Valley fever virus, Ebola virus, Sudan virus, and Marburg virus. Their analytical sensitivities ranged from 16 to 21 molecules detected (probit analysis) for the majority of RPA and RT-RPA assays. A magnetic bead-based total nucleic acid extraction method was combined with the RPAs and tested using inactivated whole organisms spiked into plasma. The RPA showed comparable sensitivities to real-time RCR assays in these extracts. The run times of the assays at 42°C ranged from 6 to 10 min, and they showed no cross-detection of any of the target genomes of the panel nor of the human genome. The RPAs therefore seem suitable for the implementation of syndromic panels onto microfluidic platforms.
Development of Written Complexity and Accuracy in an Intermediate to Advanced German L2 Setting Using Weighted Clause Ratio

Year: 2019
Subjects: German language

description: The primary focus of this study is to determine how clausal complexity and accuracy develop over the course of three academic years of intermediate to advanced-level German. This study aims to shed light on issues related to learner development of writing during advanced stages of language acquisition, particularly after conducting a study abroad. The main goal of this study will be to track the writing complexity and accuracy of multiple students longitudinally. This paper will identify Weighted Clause Ratio (Foster & Wigglesworth, 2016), as well as address Skills Acquisition Theory (DeKeyser, 2007), Interaction Hypothesis (Swain, 1985), and the Limited Attentional Capacity Theory (Skehan, 1998). In addition to this, the study will discuss the impact of a study abroad on the language-learning process, task complexity, and the language-learning plateau. Following a review of terminology, I will discuss how Weighted-Clause Ratio will be used to determine clausal accuracy and complexity. The data of this study will be analyzed with results shown in intervals throughout three academic years, comparing each of the three years with one another. Results indicate that accuracy increases drastically over the final two years when compared to the change in the first two years, confirming the effect that study abroad has on the written accuracy of learners, and the complexity showed improvements in some measures over the course of the study, but varied in other measures. I conclude the thesis by discussing by discussing the implications of these findings for our understanding of writing complexity and accuracy, and the long-term effects of study abroad.

Die qualifizierte reisemedizinische Beratung setzt besonderes Fachwissen und aktuelle, differenzierte Informationen über die Reiseländer voraus. Die Qualität der vielfältigen reisemedizinischen Beratungsangebote weicht in Deutschland stark voneinander ab und für den Reisenden ist oft nicht erkennbar, wer auf diesem Gebiet kompetent berät. Lösungsansätze für eine Verbesserung der Qualität und Transparenz in der reisemedizinischen Beratung bestehen u.a. in der Weiterentwicklung von Qualitätsstandards, in der Zertifizierung sowie öffentlichen Bekanntmachung qualifizierter Beratungsstellen und in einer engeren Zusammenarbeit von Reisebüros, Apotheken und Ärzten.
description: Travel medicine in Germany is getting more important, but also more complex in view of increasing worldwide tourism, the unbroken keenness of Germans to travel, new vaccines, changed travel habits and the altered epidemiological situation of several infectious agents. Qualified health information requires extensive specialized knowledge and up-to-date, differentiated information about travel destinations. The quality of the manifold counselling services varies considerably, and it is often difficult for the traveller seeking medical advice to make judgements about the quality of counselling. Possible solutions for the improvement of quality and transparancy in this field are seen – amongst others – in the further development of quality standards, the certification and publication of qualified information and in a closer cooperation between travel agencies, pharmacies and physicians.

When it is used in conjunction with human raters, the consistency of computers can complement human raters’ comprehensive judgments and increase efficiency in scoring (e.g., Enright & Quinlan, 2010). In search of objective and quantifiable variables that are strongly correlated with overall oral proficiency, a number of studies have reported that some utterance fluency variables (e.g., speech rate and mean length of run) might be strong predictors for L2 learners’ speaking ability (e.g., Ginther et al., 2010; Hirotani et al., 2017). However, these findings are difficult to generalize due to small sample sizes, narrow ranges of proficiency levels, and/or a lack of data from languages other than English. The current study analyzed spontaneous speech samples collected from 170 Japanese learners at a wide range of proficiency levels determined by a well-established speaking test, the American Council on the Teaching of Foreign Languages’ (ACTFL) Oral Proficiency Interview (OPI). Prior to analysis, 48 Complexity, Accuracy, Fluency (CAF) measures (with a focus on fluency variables) were calculated from the speech samples. First, the study examined the relationships among the CAF measures and learner oral proficiency assessed by the ACTFL OPI. Then, using an empirically-based approach, a feasibility of using a composite measure to predict L2 oral proficiency was investigated. The results revealed that Speech Speed and Complexity variables demonstrated strong correlation to the OPI levels, and moderately strong correlations were found for the variables in the following categories: Speech Quantity, Pause, Pause Location (i.e., Silent pause ratio within AS-unit), Dysfluency (i.e., Repeat ratio), and Accuracy. Then, a series of multiple regression analyses revealed that a combination of five CAF measures (i.e., Effective articulation rate, Silent pause ratio, Repeat ratio, Syntactic complexity, and Error-free AS-unit ratio) can predict 72.3% of the variance of the OPI levels. This regression model includes variables that correspond to Skehan’s (2009) proposed three categories of fluency (speed, breakdown, and repair) and variables that represent CAF, supporting the literature (e.g., Larsen-Freeman, 1978, Skehan, 1996).

description: In recent years, there has been an increase in the popularity of wearable sensors such as electroencephalography (EEG) sensors, electromyography (EMG) sensors, gyroscopes, accelerometers, and photoplethysmography (PPG) sensors. This work is focused on PPG sensors, which are used to measure heart rate in real time. They are currently used in many commercial products such as Fitbit Watch and Muse Headband. Due to their low cost and relative implementation simplicity, they are easy to add to custom-built wearable devices.
 We built an Arduino-based wearable wrist sensor-kit that consists of a PPG sensor in addition to other low cost commercial biosensors to measure biosignals such as pulse rate, skin temperature, skin conductivity, and hand motion. The purpose of the sensor-kit is to analyze the effects of stress on students in a classroom based on changes in their biometric signals. We noticed some failures in the measured PPG signal, which could negatively affect the accuracy of our analysis. We conjectured that one of the causes of failure is movement. Therefore, in this thesis, we build automatic failure detection methods and use these methods to study the effect of movement on the signal.
 Using the sensor-kit, PPG signals were collected in two settings. In the first setting, the participants were in a still sitting position. These measured signals were manually labeled and used in signal analysis and method development. In the second setting, the signals were acquired in three different scenarios with increasing levels of activity. These measured signals were used to investigate the effect of movement on the reliability of the PPG sensor.
 Four types of failure detection methods were developed: Support Vector Machines (SVM), Deep Neural Networks (DNN), K-Nearest Neighbor (K-NN), and Decision Trees. The classification accuracy is evaluated by comparing the resulting Receiver Operating Characteristic (ROC) curves, Area Above the Curve (AAC), as well as the duration of failure and non-failure sequences. The DNN and Decision Tree results are found to be the most promising and seem to have the highest error detection accuracy. The proposed classifiers are also used to assess the reliability of the PPG sensor in the three activity scenarios. Our findings indicate that there is a significant presence of failures in the measured PPG signals at rest, which increases with movement. They also show that it is hard to obtain long sequences of pulses without failure. These findings should be taken into account when designing wearable systems that use heart rate values as input.

description: The clinical spectrum following infection with Shiga toxin-producing Escherichia coli (STEC) is wide ranging and includes hemorrhagic colitis and life-threatening hemolytic uremic syndrome (HUS). Severity of STEC illness depends on patients' age and strongly on the infecting strains' virulence. Serogroup O157 is often assumed to be more virulent than others. Age-adjusted population-based data supporting this view are lacking thus far. We conducted a large retrospective cohort study among patients of community-acquired gastroenteritis or HUS diagnosed with STEC infection, reported in Germany January 2004 through December 2011. Age-adjusted risks for reported hospitalization and death, as proxies for disease severity, were estimated for STEC serogroups separately, and compared with STEC O157 (reference group) using Poisson regression models with robust error estimation. A total of 8,400 case-patients were included in the analysis; for 2,454 (29%) and 30 (0.4%) hospitalization and death was reported, respectively. Highest risks for hospitalization, adjusted for age and region of residence, were estimated for STEC O104 (68%; risk ratio [RR], 1.33; 95% confidence interval [CI], 1.19–1.45), followed by STEC O157 (46%). Hospitalization risks for the most prevalent non-O157 serogroups (O26, O103, O91, O145, O128, O111) were consistently and markedly lower than for O157, with the highest RR for O145 (0.54; 95% CI, 0.41–0.70) and the lowest for O103 (0.27; 95% CI, 0.20–0.35). Mortality risk of O104 was similar to O157 (1.2% each), but the group of all other non-O157 STEC had only 1/10 the risk (RR, 0.09; 95% CI, 0.02–0.32) compared to O157. The study provides population-based and age-adjusted evidence for the exceptional high virulence of STEC O157 in relation to non-O157 STEC other than O104. Timely diagnosis and surveillance of STEC infections should prioritize HUS-associated E. coli, of which STEC O157 is the most important serogroup.

description: Gas turbine engines have operated on the Brayton cycle for decades, each decade only gaining approximately one to two percent in thermal efficiency as a result of effortsto improve engine performance. Pressure-gain combustion in place of constant-pressure combustion in a Brayton cycle could provide a drastic step-change in the thermal efficiency of these devices, leading to reductions in fuel consumption and emissions production. Rotating Detonation Engines (RDEs) have been widely researched as a viable option for pressure-gain combustion. Due to the extremely high frequencies associated with operation of an RDE, the development and application of high-speed diagnostics techniques for RDEs is necessary to further understand anddevelop these devices.
An application of high-speed diagnostic techniques in a natural gas-air RDE at conditions relevant to land-based power generation is presented. Diagnostics included high-frequency chamber pressure measurements, chemiluminescence imaging of the annulus, and Particle Image Velocimetry (PIV) measurements at the exit plane of the RDE. Results from a case with two detonation waves rotating clockwise (aft looking forward) in the combustor annulus are presented. Detonation surface plots are created from chemiluminescence images and allow for the extraction of properties such as dominant frequency modes and wave number, speed, and direction. The chamber frequency for the case with two co-rotating waves in the chamber is found to be 3.46 kHz and corresponds to average individual wave speeds of 68% Chapman-Jouguet (CJ) velocity. Dynamic Mode Decomposition (DMD) is applied and indicates the presence of two strong detonation waves rotating clockwise and periodically intersecting with weaker, counter-rotating waves in the annulus at certain times during operation. Singular-Spectrum Analysis (SSA) is used to isolate modes corresponding to the detonation frequency in the signals of velocity components obtained from PIV, maintaining instantaneous phase information. Axial and azimuthal components of velocity are observed to remain nearly 180 degrees out of phase. Lastly, approximate angles for the trailing oblique shocks in the combustion chamber are calculated.
