Currie, Therese Dowswell, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: Maternal mortality has declined by nearly half since 1990, but over a quarter million women still die every year of causes related to pregnancy and childbirth. Maternal-health related targets are falling short of the2015 Millennium Development Goals and a post-2015 Development Agenda is emerging. In connection with this, setting global research priorities for the next decade is now required.

Methods: We adapted the methods of the Child Health and Nutrition Research Initiative (CHNRI) to identify and set global research priorities for maternal and perinatal health for the period 2015 to 2025. Priority research questions were received from various international …

Newborn Care In Indonesia, Lao People’S Democratic Republic And The Philippines: A Comprehensive Needs Assessment, Els Duysburgh, Birgit Kerstens, Melissa Diaz, Vini Fardhdiani, Katherine Ann Reyes, Khamphong Phommachanh, Marleen Temmerman, Basil Rodriques, Nabila Zaka

Obstetrics and Gynaecology, East Africa

Background: Between 1990 and 2011, global neonatal mortality decline was slower than that of under-five mortality. As a result, the proportion of under-five deaths due to neonatal mortality increased. This increase is primarily a consequence of decreasing post-neonatal and child under-five mortality as a result of the typical focus of child survival programmes of the past two decades on diseases affecting children over four weeks of age. Newborns are lagging behind in improved child health outcomes. The aim of this study was to conduct a comprehensive, equity-focussed newborn care assessment and to explore options to improve newborn survival in Indonesia, …

Obstetrics and Gynaecology, East Africa

Background: Antenatal care (ANC) reduces maternal and perinatal morbidity and mortality directly through the detection and treatment of pregnancy-related illnesses, and indirectly through the detection of women at increased risk of delivery complications. The potential benefits of quality antenatal care services are most significant in low-resource countries where morbidity and mortality levels among women of reproductive age and neonates are higher. WHO developed an ANC model that recommended the delivery of services scientifically proven to improve maternal, perinatal and neonatal outcomes. The aim of this study is to determine the effect of an intervention designed to increase the use of …

The aim of this study was to evaluate the in vitro and in vivo efficacy of praziquantel baths against L. floridanus on I. punctatus. In vitro experiments evaluated L. floridanus attached and unattached to gills; for this, parasites were exposed to 2, 5, and 10 mg L-1 of praziquantel in distilled or fish aquarium water, and saline …

Langmuir Probe Instrument Suite For Mesosphere Turbulence Experiment Mission, Adam Blake

Doctoral Dissertations and Master's Theses

The Langmuir probe technique is the predominant in-situ plasma diagnostic technique, and is arguably the only measurement technique that is universally own on every sounding rocket investigation. Earth's mesosphere region (80-120 km) is a host of many dynamic phenomena such as the noctilucent clouds, breaking gravity waves, inversion layers, settlement of mesospheric smoke particles, etc. As such it is critical to have a comprehensive suite of plasma diagnostics that can unambiguously measure various plasma parameters.

This thesis deals with the development and testing of three different Langmuir probe implementations suitable for investigation of the mesosphere which are to be launched …

Development Of An Exteroceptive Sensor Suite On Unmanned Surface Vessels For Real-Time Classification Of Navigational Markers, Christopher Lloyd Kennedy

Doctoral Dissertations and Master's Theses

This thesis presents the development of an exteroceptive sensor suite for real-time detection and classification of navigational markers on Unmanned Surface Vessels. Three sensors were used to complete this task: a 3D LIDAR and two visible light cameras. First, all LIDAR points were transformed from the sensor’s reference frame to the local frame using a Kalman filter to estimate instantaneous vehicle pose. Next, objects were chosen from the LIDAR data to be classified using either Multivariate Gaussian or Parzen Window Classifiers. Both produce 96% accuracy or better, however, multivariate Gaussian ran considerably faster than the Parzen and was simpler to …

Design And Dynamic Analysis Of A Variable-Sweep, Variable-Span Morphing Uav, Nirmit Prabhakar

Doctoral Dissertations and Master's Theses

Morphing wings have the potential to optimize UAV performance for a variety of flight conditions and maneuvers. The ability to vary both the wing sweep and span can enable maximum performance for a diverse range of flight regimes. For example, low-speed missions can be optimized using a wing with high aspect ratio and no wing sweep whereas high-speed missions are optimized with low aspect ratio wings and large wing sweep. Different static morphing wing configurations clearly result in varying aerodynamics and, as a result, varying dynamic modes. Another important consideration, however, is the transient dynamics that occur when transitioning between …

Characterization Of Electron Number Density Of Rocket Exhaust Plumes Through Microwave Transmissions, Jorge Torres

Doctoral Dissertations and Master's Theses

Charged rocket plumes generally exceed the length of their source vehicles, and offer lightning a favorable path to ground. Rocket plumes enhance the induced transient currents in flight electronics, and increase the risk of vehicle failure. The affinity of lightning to the plume can be associated with the plume's electrical properties, which are coupled to plasma characteristics including the electron number density. However, the electron number density of rocket plumes is not well-known. In this study, the electron number density is characterized through data from static rocket firings. A model of the plume in finite difference time domain (FDTD) simulations …

Human Behavior During Spaceflight: Evidence From An Analog Environment, Kenny Mikael Arnaldi

Doctoral Dissertations and Master's Theses

Spaceflight offers a multitude of stressors to humans living and working in space, originating from the external space environment and the life-support system. Future space participants may be ordinary people with different medical and psychosocial backgrounds who may not receive the intense spaceflight preparation of astronauts. Consequently, during a mission, a space participant’s mood and behavior could differ from a trained astronaut. This study was an exploratory research project that used an artificial habitat to replicate an orbital environment and the activities performed by humans in space. The study evaluated whether the type of environment affects mood and temperament. Two …

Development Of A System Architecture For Unmanned Systems Across Multiple Domains, Charles Randall Breingan Jr.

Doctoral Dissertations and Master's Theses

In the unmanned systems industry, there is no common standard for systems components, connections and relations. Such a standard is never likely to exist. Needless to say, a system needs to have the components that are required for the application, however, it is possible to abstract the common functionality out of an individual implementation. This thesis presents a universal unmanned systems architecture that collects all of the common features of an unmanned system and presents them as a set of packages and libraries that can be used in any domain of unmanned system operation. The research and design of the …

A New Hedonic Regression For Real Estate Prices Applied To The Singapore Residential Market, Liang Jiang, Peter C.B. Phillips, Jun Yu

Cowles Foundation Discussion Papers

This paper develops a new hedonic method for constructing a real estate price index that utilizes all transaction price information that encompasses both single-sale and repeat-sale properties. The new method is less prone to specification errors than standard hedonic methods and uses all available data. Like the Case-Shiller repeat-sales method, the new method has the advantage of being computationally efficient. In an empirical analysis of the methodology, we fit the model to all transaction prices for private residential property holdings in Singapore between Q1 1995 and Q2 2014, covering several periods of major price fluctuation and changes in government macroprudential …

Mathematical Modeling Of Immune Responses To Hepatitis C Virus Infection, Ivan Ramirez

Electronic Theses and Dissertations

An existing mathematical model of ordinary differential equations was studied to better understand the interactions between hepatitis C virus (HCV) and the immune system cells in the human body. Three possible qualitative scenarios were explored: dominant CTL response, dominant antibody response, and coexistence. Additionally, a sensitivity analysis was carried out to rank model parameters for each of these scenarios. Therapy was addressed as an optimal control problem. Numerical solutions of optimal controls were computed using a forward-backward sweep scheme for each scenario. Model parameters were estimated using ordinary least squares fitting from longitudinal data (serum HCV RNA measurements) given in …

Factors Impacting Success In Ninth Grade Algebra I For High School Students, James M. Lamie

Electronic Theses and Dissertations

The implementation of the Common Core State Standards (CCSS, 2013), No Child Left Behind Act of 2001, and the Race to the Top initiative of 2009 has placed a greater emphasis on high stakes testing. A renewed emphasis on math education for all students and their ability to succeed in high school mathematics place new challenges on today’s classroom teachers. Although the belief is that with new standards and best teaching strategies students will improve their test scores, there are multiple factors that can serve as deterrents to the success in mathematics for at-risk high school students (Balfanz, 2009). The …

Cloning And Expression Of A Tobacco Stearoyl-Acp Desaturase Gene Sbip24 And Its Interaction With Sabp2 In Sa Pathway, Amin J. Ferdous

Electronic Theses and Dissertations

Salicylic acid binding protein 2 (SABP2) that converts methyl salicylate to salicylic acid (SA) plays an obligatory role in the SA-mediated disease resistance pathway in plants. SABP2 interacts with SBIP24 in a yeast two-hybrid screening. SBIP24 belongs to the stearoyl-acyl carrier protein-desaturase protein family. To biochemically characterize the SBIP24, it was cloned from tobacco leaves using RT-PCR and expressed in E. coli. Recombinant SBIP24 was affinity purified using Ni-NTA chromatography. RT-PCR was performed to determine the role of SABP2 in modulating the expression SBIP24. TMV infected transgenic C3 (control tobacco plant containing empty silencing vector) and 1-2 (SABP2-silenced) …

Impulsivity, Venturesomeness, And Pride: Potential Moderators Of The Relationship Between Childhood Trauma, Substance Use, And Physical Aggression, Joshua P. Hatfield

Electronic Theses and Dissertations

Impulsivity, venturesomeness, and pride variables were examined as potential moderators of the associations between childhood trauma and physical aggression, alcohol use and physical aggression, and drug use and physical aggression. Participants (n = 457) were college students recruited from a university in the Southeast. It was hypothesized that childhood trauma, alcohol use, and drug use would be associated with increased scores of physical aggression. In addition, it was hypothesized that impulsivity, venturesomeness, authentic pride, and hubristic pride would moderate these relationships. Linear, multivariate hierarchical regression analyses were used to examine these variables as potential moderators. Hypotheses concerning hubristic pride as …

Collaborative Models Of Care In The Appalachian Region Of Tennessee: Examining Relationships Between Level Of Collaboration, Clinic Characteristics, And Barriers To Collaboration, Jeffrey Ellison

Electronic Theses and Dissertations

Decades of research have shown that there are significant advantages to maintaining close communicative and collaborative relationships between primary care and behavioral health providers. Fiscal, structural, and systemic barriers, however, often restrict the degree to which such interprofessional collaboration can occur. In the present study the authors examined relationships between primary care clinics in the Appalachian region’s characteristics (i.e., clinic type, rurality, and clinic size), barriers (i.e., fiscal, structural, and systemic) reported to using increased collaboration, and the level of collaboration used at a particular clinic.

For the present study 136 surveys were completed by providers working in primary care …

Cellular-Based Brain Pathology In The Anterior Cingulate Cortex Of Males With Autism Spectrum Disorder, Jessica D. Crawford

Electronic Theses and Dissertations

Autism spectrum disorder (ASD) now affects 1 in 68 children in the United States. Disorders within this spectrum share hallmark deficits in verbal and nonverbal communication, repetitive behavior, and social interaction. The cause of ASD is still unknown. Even though hundreds of genetic abnormalities have been identified in ASD, these markers account for less than 1% of all ASD cases. Researchers continue to search for pathological markers common to all or most cases of ASD. The research presented in this dissertation used a novel combination of state-of-the-art methods to investigate brain pathology in ASD. Postmortem anterior cingulate cortex (ACC) from …

Hif-1Α In The Heart: Provision Of Ischemic Cardioprotection And Remodeling Of Nucleotide Metabolism, Joe Wu

Electronic Theses and Dissertations

In our studies we found that stabilized expression of HIF-1α in heart led to better recovery of function and less tissue death after 30 minutes of global ischemia, via mechanisms that preserve the mitochondrial polarization. Our group previously showed that HIF-1α conferred ischemic tolerance by allowing cardiomyocytes to use fumarate as an alternative terminal electron acceptor to sustain anaerobic mitochondrial polarization. The source of fumarate was identified as the purine nucleotide cycle (PNC). Here we discovered that HIF-1α upregulates AMP deaminase 2 (AMPD2), the entry point to the PNC. The combination of glycolysis and the PNC may protect the heart's …

The Effects Of Vertically-Oriented Resistance Training On Golf Swing Performance Variables, Austin R. Driggers

Electronic Theses and Dissertations

The purpose of this study was to examine the effects of vertically-oriented resistance training on golf driving performance. Ten Division-I collegiate golfers completed 2 resistance training sessions per week for 10 weeks during the fall tournament season. Pre- and posttraining assessments of strength-power and golf performance were compared. To assess strength-power, jump height, peak force, and peak power (PP) were measured from static and countermovement (CMJ) vertical jumps; peak force and rate of force development from 0-250 ms were measured from an isometric mid-thigh pull. Golf performance was assessed in terms of ball launch speed (BS), spin rate, carry yardage …

A Comprehensive Study Of The Effects Of Neurotoxins On Noradrenergic Phenotypes, Neuronal Responses And Potential Intervention By Antidepressants In Noradrenergic Cells, Yan Wang

Electronic Theses and Dissertations

It has been reported that locus coeruleus (LC) degeneration precedes the degeneration of other neurons in the brain in some neurodegenerative diseases like Alzheimer’s disease (AD) and Parkinson’s disease (PD). However, the precise mechanisms of neurodegeneration remain to be elucidated. N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP4) has been widely used as a noradrenergic neurotoxin in the development of AD and PD animal models for specific LC degeneration. However, the precise mechanism of action of DSP4 remains unclear. An increased systemic DNA damage caused by neurotoxin or oxidative stress has been found to be related to the pathogenic development of neurodegeneration. The process of neurodegeneration …

Identification, Cloning, And Expression Of Tobacco Responsive To Dehydration Like Protein (Rd22), Sbip-355 And Its Role In Sabp2 Mediated Sa Pathway In Plant Defense, Hanadi Abdulaali Almazroue

Electronic Theses and Dissertations

Abscisic acid (ABA) induces RD22, responsive to dehydration stress gene. Salicylic acid (SA) has been the focus of research due to its role against pathogens and abiotic stress. Interaction between ABA and SA signaling pathways is still poorly understood. SA-Binding Protein 2 (SABP2) converts methyl salicylate to SA. An attempt was made to identify proteins that interact with SABP2 using a yeast 2-hybrid screening. Several interactors were identified. One of them, SA-Binding Protein 2 Interacting Protein-355 (SBIP-355), showed high homology to RD22. Bioinformatic approaches showed that SBIP-355 contains a BURP domain. Phylogenetic analysis reveals that SBIP-355 clustered into the …
