Cytochrome P450 Gene Expression Modulates Anoxia Sensitivity in Caenorhabditis Elegans

Cytochrome P450 Gene Expression Modulates Anoxia Sensitivity in Caenorhabditis Elegans

Date: August 2016
Creator: Quan, Daniel L
Description: With an increasing population suffering from obesity or Diabetes Mellitus (DM), it is more pertinent than ever to understand how physiological changes impact cellular processes. Patients with DM often suffer from obesity, hyperglycemia, altered fatty acids that contribute to vascular dysfunction, and increased risk to ischemia. Caenorhabditis elegans is a model system used to study the conserved insulin signaling pathway, cellular responses in whole organisms and the impact a glucose diet has on oxygen deprivation (anoxia) responses. RNA-sequencing (RNA-Seq) was used to analyze the expression of genes in the anoxia sensitive populations of N2 (wild-type) fed glucose and hyl-2(tm2031), a mutant with altered ceramide metabolism. Comparison of the altered transcripts in the anoxia sensitive populations revealed 199 common transcripts- 192 upregulated and 7 downregulated. One of the gene families that have altered expression in the anoxia sensitive populations encode for Cytochrome P450 (CYP). CYPs are located both in the mitochondria and endoplasmic reticulum (ER), but the CYPs of interest are all predicted to be mainly subcellularly localized to the ER. Here, I determined that knock-down of specific cyp genes, using RNA interference (RNAi), increased anoxia survival in N2 animals fed a standard diet. Anoxia sensitivity of the hyl-2(tm2031) animals was ...

Development of a Self-Report Measure of Post-Traumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD) According to the Eleventh Edition of the International Classification of Diseases (ICD-11): The Complex Trauma Inventory

Development of a Self-Report Measure of Post-Traumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD) According to the Eleventh Edition of the International Classification of Diseases (ICD-11): The Complex Trauma Inventory

Date: August 2016
Creator: Litvin, Justin M
Description: The work group editing trauma disorders for the upcoming edition of the International Classification of Diseases (ICD-11) made several changes. Specifically, they significantly simplified the guidelines for post-traumatic stress disorder (PTSD) and added a new trauma disorder called complex PTSD (CPTSD). The new domains for PTSD and the addition of CPTSD require new instruments to assess these novel constructs. We developed a measure of PTSD and CPTSD (Complex Trauma Inventory; CTI) according to the proposed ICD-11 domains, creating several items to assess each domain. We examined the factor structure of the CTI (using both exploratory and confirmatory factor analyses) in two separate samples of diverse college students (n1 = 501; n2 = 500), reducing the original 53 trauma items in the item pool to 21 items. Confirmatory factor analyses supported two highly-correlated second-order factors (PTSD and complex factors), with PTSD (i.e., re-experiencing, avoidance, hyper-arousal) and complex factors (i.e., affect dysregulation, alterations in self-perception and alterations in relationships with others) each loading on three of the six ICD-11-consistent first-order factors (RMSEA = .08, CFI = .92, GFI = .87, SRMR = .06). Internal consistency for PTSD (α = .92) and complex factors (α = .93) are excellent.

Does Downhill Running Alter Monocyte Susceptibility to Apoptosis?

Does Downhill Running Alter Monocyte Susceptibility to Apoptosis?

Date: August 2016
Creator: Pennel, Kathryn Ann Foster
Description: Introduction/purpose: Recovery from muscle damage involves a type of programmed cell death known as apoptosis. Damage Associated Molecular Patterns (DAMPs) are released after muscle damage and may cause premature apoptosis in monocytes infiltrating the damaged site. This may alter the time course of events towards recovery. Therefore, the purpose of this study was to investigate if downhill running causes a change in the susceptibility of monocytes to apoptosis. Methods: Participants (5 male, 6 female) completed a downhill running protocol consisting of 6-5 minute bouts at a speed of 6-9mph on a -15% grade treadmill. Venous blood samples were collected immediately pre-exercise (PRE), in addition to 4 -h, 24 -h and 48 -h post-exercise. Creatine kinase (CK) was measured to give an indication of muscle damage. Monocytes were analyzed by flow cytometry for expression of multicaspase and annexin v reagent was used to detect changes in the plasma membrane. A MILLIPLEX MAP human early apoptosis magnetic bead 7-plex kit (EMD Millipore, Billerica, MA) was used to assess the relative concentration of phosphorylated protein kinase B (Akt), Bcl-2 associated death promoter (BAD), B cell lymphoma-2 (Bcl-2), active caspase-8, active caspase-9, c jun N terminal kinase (JNK) and tumor protein p53 by Luminex ...

The Effects of Fluency-Based Instruction on the Identification of Component Reading Skills

The Effects of Fluency-Based Instruction on the Identification of Component Reading Skills

Date: August 2016
Creator: Bandy, Darren
Description: This study examined the effects of fluency-based instruction on the identification of six component-composite relations for early reading skills. Five participants (ages 5-8) who struggled with reading participated. A multiple probe design was used to assess the effects of frequency building on prerequisite skills on the emergence of composite reading skills. The results show that the prerequisite skills taught did not have an effect on the composite skill probes but did have an effect on the assessment scores. The data expand the research pertaining to Precision Teaching, fluency-based instruction, and component-composite relations. These data suggest that additional skills may be needed to be taught in order to effects on the composite skills. In addition, these authors identify the need for the identification of the component skills necessary to teach rapid autonomic naming.

The Effects of Naturalistic Language Interventions in Children with Autism

The Effects of Naturalistic Language Interventions in Children with Autism

Date: August 2016
Creator: Degner, Brittany
Description: Several evidence-based procedures based upon operant learning principles have been developed to teach language, and for young children with autism spectrum disorder (ASD), naturalistic interventions are commonly implemented as they are both effective and developmentally appropriate. The current investigation compared contingent responsive intervention and combined intervention on the effects of language use in four children diagnosed with ASD. Results suggest that a combined intervention procedure increases target language and requests in children with simplified language (e.g., one-word phrase) as well as complex language (e.g., simple sentences).

Effects of UE Speed on MIMO Channel Capacity in LTE

Effects of UE Speed on MIMO Channel Capacity in LTE

Access: Use of this item is restricted to the UNT Community.
Date: August 2016
Creator: Shukla, Rahul
Description: With the introduction of 4G LTE, multiple new technologies were introduced. MIMO is one of the important technologies introduced with fourth generation. The main MIMO modes used in LTE are open loop and closed loop spatial multiplexing modes. This thesis develops an algorithm to calculate the threshold values of UE speed and SNR that is required to implement a switching algorithm which can switch between different MIMO modes for a UE based on the speed and channel conditions (CSI). Specifically, this thesis provides the values of UE speed and SNR at which we can get better results by switching between open loop and closed loop MIMO modes and then be scheduled in sub-channels accordingly. Thus, the results can be used effectively to get better channel capacity with less ISI. The main objectives of this thesis are: to determine the type of MIMO mode suitable for a UE with certain speed, to determine the effects of SNR on selection of MIMO modes, and to design and implement a scheduling algorithm to enhance channel capacity.

Evaluation of an Observation and Training System to Increase Play Skills in Young Children with Autism

Evaluation of an Observation and Training System to Increase Play Skills in Young Children with Autism

Date: August 2016
Creator: Van Meter, Sarah M
Description: Play is considered to be important for the development of young children in that it provides a means to expand their interests, promote engagement and learning, and increase social interactions. Children with autism, however, display deficits in play skills, such as lack of pretend play and rigid or stereotyped manners of play. Research suggests supported play techniques, such as reciprocal imitation training, play expansions, and scaffolding increase play skills in children diagnosed with autism. The current study evaluated the effects of a training package to teach staff members supported play techniques to six young children diagnosed with autism. The study employed a concurrent multiple baseline design across two preschool classrooms. The results suggest that the training package successfully increased staff member use of the supported play techniques and child and staff engagement. The training, however, did not have consistent effects on child social engagement (proximity, attending, and initiating) or on the types of child play (simple manipulation, advanced manipulation, and pretend play). Staff member responses to the post-intervention satisfaction and feedback survey were positive and the results are discussed in the context of the observation procedures and directions for future studies.

An Exploration of College Attitudes among Sioux Falls High School Students

An Exploration of College Attitudes among Sioux Falls High School Students

Date: August 2016
Creator: Duesterhoeft, Kristin
Description: Since the recession of 2008, there has been an increased scrutiny of higher education, with little research done on how this affects high school students' college search process. This study seeks to understand how college perceptions are formed and how they affect the college decision process of high school students in Sioux Falls, South Dakota. In order to gain a holistic perspective of this process, this study utilized a mixed method approach of analyzing public data, conducting interviews with community members and students, conducting a focus group with high school guidance counselors, and administering a survey to high school students. This study found that students in this area form their perceptions of college in three distinct phases and that these phases affect a student's college priorities. Special attention was given to how academics, cost and location contributed to a student's overall college decision. These findings can be used to assist faculty and staff at higher education institutions in creating effective messaging and programming that relate to this group of students.

Feasibility Study of Consolidation by Direct Compaction and Friction Stir Processing of Commercially Pure Titanium Powder

Feasibility Study of Consolidation by Direct Compaction and Friction Stir Processing of Commercially Pure Titanium Powder

Date: August 2016
Creator: Nichols, Leannah Marie
Description: Commercially pure titanium can take up to six months to successfully manufacture a six-inch in diameter ingot in which can be shipped to be melted and shaped into other useful components. The applications to the corrosion-resistant, light weight, strong metal are endless, yet so is the manufacturing processing time. At a cost of around $80 per pound of certain grades of titanium powder, the everyday consumer cannot afford to use titanium in the many ways it is beneficial simply because the number of processing steps it takes to manufacture consumes too much time, energy, and labor. In this research, the steps it takes from the raw powder form to the final part are proposed to be reduced from 4-8 steps to only 2 steps utilizing a new technology that may even improve upon the titanium properties at the same time as it is reducing the number of steps of manufacture. The two-step procedure involves selecting a cylindrical or rectangular die and punch to compress a small amount of commercially pure titanium to a strong-enough compact for transportation to the friction stir welder to be consolidated. Friction stir welding invented in 1991 in the United Kingdom uses a tool, similar to ...

Identification of a Potential Factor Affecting Graduation Rates in STEM for Hispanic Students at the University of North Texas, via Analysis of Nonfiction Science Books in Spanish Language for ELLs in the Dallas ISD Schools

Date: August 2016
Creator: Garcia Colin, Monica
Description: Latinos are the largest minority group in the U.S.; however despite the continuous growth of the Hispanic population, Latinos are severely underrepresented in STEM fields. One of the reasons that might explain why Latinos do not major in STEM is the way they encounter science curriculum in primary school. Students' limited proficiency in English may constrain their science achievement when instruction is delivered exclusively in English. A quantitative analysis with graduation rates in STEM from 2009 to 2014 at the University of North Texas was conducted, finding that there is a significant difference (p<0.05) in the number of bachelor's degrees in STEM between Hispanic, White, African American and other student populations. Interviews with teachers, librarians and publishing companies were performed to describe the limited science literature in Spanish at the Dallas ISD schools. Improving science literacy by teaching according to ELLs' linguistic skills and culture may lead to a better understanding of science curriculum throughout their education, which may translate into higher college graduation rates by Hispanic recipients in STEM.

Imagining the Empire: Germany Through the Eyes of Early Modern English Travellers

Imagining the Empire: Germany Through the Eyes of Early Modern English Travellers

Date: August 2016
Creator: Micheals, Isaac
Description: This thesis is a study of early modern English travel narratives and the ways they presented the German states and their people to the public through the medium of print. It is based on an analysis of forty seven published travel narratives written by men and women who toured Germany and wrote about their experiences. The study situates these writings in the context of the growing sense of national identity in early modern Europe and offers an assessment of how these travel narratives contributed to a uniquely English understanding of Germany. As English travel narratives about Germany in the early modern period evolved, writers highlighted distinctive characteristics they believed Germans possessed, and compared their subjects to themselves. Travelers presented diverse and even conflicting views on a variety of subjects related to Germany. Nevertheless, by the late eighteenth century, English travelers had fashioned a common set of images, stereotypes, and characteristics of Germany and its people.

The Impact of Chinese Privet (Ligustrum Sinense) on the Survival and Re-Establishment of Native Plants at the Dallas Floodway Extension

The Impact of Chinese Privet (Ligustrum Sinense) on the Survival and Re-Establishment of Native Plants at the Dallas Floodway Extension

Date: August 2016
Creator: Barnett, Jennifer M
Description: Invasive woody shrubs are a problem when they displace native species and threaten habitats, especially those that harbor rare or endangered species. They not only compete with native plants, but also alter habitat and food that many organisms depend upon. Invasive plants undergo a release from their specialist predators in the nonnative range, providing them advantages over native species. Because modes and pathways of how invasive species spread are not fully understood, predicting spread and implementing restoration ecological controls remain inexact. Due to the lack of comparative studies on woody shrubs, especially invasive privets, we understand very little about conditions affecting their invasiveness. A study was conducted near Dallas, Texas to determine if privet has allelopathic properties that influences growth of native plants. Soil nutrients and other analyses were made and compared between field plots supporting privet, plots in which privet has been removed, and plots where privet has not been observed. In some field plots, natives were planted under the three previously mentioned conditions, and their survival and condition were monitored to evaluate effects of privet on their establishment and growth. It was found that Chinese privet did hinder seed germination in red mulberry, soapberry and beautyberry and root ...

Influence of a Human Lipodystrophy Gene Homologue on Neutral Lipid Accumulation in Arabidopsis Leaves

Influence of a Human Lipodystrophy Gene Homologue on Neutral Lipid Accumulation in Arabidopsis Leaves

Date: August 2016
Creator: James, Christopher Neal
Description: CGI-58 is the defective gene in the human neutral lipid storage disease called Chanarin-Dorfman syndrome. This disorder causes intracellular lipid droplets to accumulate in nonadipose tissues, such as skin and blood cells. Here, disruption of the homologous CGI-58 gene in Arabidopsis thaliana resulted in the accumulation of neutral lipid droplets in mature leaves. Mass spectroscopy of isolated lipid droplets from cgi-58 loss-of-function mutants showed they contain triacylglycerols with common leaf specific fatty acids. Leaves of mature cgi-58 plants exhibited a marked increase in absolute triacylglycerol levels, more than 10-fold higher than in wild-type plants. Lipid levels in the oil-storing seeds of cgi-58 loss-of-function plants were unchanged, and unlike mutations in beta-oxidation, the cgi-58 seeds germinated and grew normally, requiring no rescue with sucrose. We conclude that the participation of CGI-58 in neutral lipid homeostasis of nonfat-storing tissues is similar, although not identical, between plant and animal species. This unique insight may have implications for designing a new generation of technologies that enhance the neutral lipid content and composition of corp plants.

Knowledge Based System and Decision Making Methodologies in Materials Selection for Aircraft Cabin Metallic Structures

Knowledge Based System and Decision Making Methodologies in Materials Selection for Aircraft Cabin Metallic Structures

Date: August 2016
Creator: Adhikari, Pashupati Raj
Description: Materials selection processes have been the most important aspects in product design and development. Knowledge-based system (KBS) and some of the methodologies used in the materials selection for the design of aircraft cabin metallic structures are discussed. Overall aircraft weight reduction means substantially less fuel consumption. Part of the solution to this problem is to find a way to reduce overall weight of metallic structures inside the cabin. Among various methodologies of materials selection using Multi Criterion Decision Making (MCDM) techniques, a few of them are demonstrated with examples and the results are compared with those obtained using Ashby's approach in materials selection. Pre-defined constraint values, mainly mechanical properties, are employed as relevant attributes in the process. Aluminum alloys with high strength-to-weight ratio have been second-to-none in most of the aircraft parts manufacturing. Magnesium alloys that are much lighter in weight as alternatives to the Al-alloys currently in use in the structures are tested using the methodologies and ranked results are compared. Each material attribute considered in the design are categorized as benefit and non-benefit attribute. Using Ashby's approach, material indices that are required to be maximized for an optimum performance are determined, and materials are ranked based on the ...

Looking Outward from the Village: The Contingencies of Soil Moisture on the Prehistoric Farmed Landscape near Goodman Point Pueblo

Date: August 2016
Creator: Brown, Andrew D
Description: Ancestral Pueblo communities of the central Mesa Verde region (CMVR) became increasingly reliant on agriculture for their subsistence needs during Basketmaker III (BMIII) through Terminal Pueblo III (TPIII) (AD 600–1300) periods. Researchers have been studying the Ancestral Pueblo people for over a century using a variety of methods to understand the relationships between climate, agriculture, population, and settlement patterns. While these methods and research have produced a well-developed cultural history of the region, studies at a smaller scale are still needed to understand the changes in farming behavior and the distribution of individual sites across the CMVR. Soil moisture is the limiting factor for crop growth in the semi-arid region of the Goodman Watershed in the CMVR. Thus, I constructed the soil moisture proxy model (SMPM) that is on a local scale and focuses on variables relevant to soil moisture – soil particle-size, soil depth, slope, and aspect. From the SMPM output, the areas of very high soil moisture are assumed to represent desirable farmland locations. I describe the relationship between very high soil moisture and site locations, then I infer the relevance of that relationship to settlement patterns and how those patterns changed over time (BMIII – TPIII). The ...

Married in a Frisky Mode: Clandestine and Irregular Marriages in Eighteenth-Century Britain

Married in a Frisky Mode: Clandestine and Irregular Marriages in Eighteenth-Century Britain

Date: August 2016
Creator: Smith, Summer
Description: The practice of irregular and clandestine marriage ran rampant throughout Britain for centuries, but when the upper class felt they needed to reassert their social supremacy, marriage was one arena in which they sought to do so. The restrictions placed on irregular marriages were specifically aimed at protecting the elite and maintaining a separation between themselves and the lower echelon of society. The political, social, and economic importance of marriage motivated its regulation, as the connections made with the matrimonial bond did not affect only the couple, but their family, and, possibly, their country. Current historiography addresses this issue extensively, particularly in regards to Lord Hardwicke's Marriage Act of 1753 in England. There is, however, a lack of investigation into other groups that influenced and were influenced by the English approach to clandestine marriage. The Scots, Irish, and British military all factor into the greater landscape of clandestine marriage in eighteenth-century Britain and an investigation of them yields a more complete explanation of marital practices, regulations, and reactions to both that led to and stemmed from Hardwicke's Act. This explanation shows the commonality of ideas among Britons regarding marriage and the necessity of maintaining endogamous unions for the benefit of ...

The Modeling and Simulation of EV3 Motor Dynamics

Date: August 2016
Creator: Norouzi Kandalan, Roya
Description: This paper describes a procedure to find the transfer function for the Lego Mindstorms Ev3. Lego Mindstorms Ev3 can serve as the platform for a system modeling and a controller design course. It is economical and accessible. It is also very compatible with Matlab and Simulink. This platform can be used for concepts of modeling, feedback, and controller design. The main approach in this work focuses on the closed loop instead of open loop. Although this approach turns the problem into a more complicated puzzle, it reveals more details. In this work, different techniques have been used, such as time domain, root locus, and least square estimation. Different tools have also been utilized such as Matlab SISO tool, the Matlab System Identification tool, and Simulink. These methods and implementations assisted to acquire different types of transfer functions for the system. By simulating the transfer functions and comparing them with experimental studies, the matching scores were calculated to decide on the best transfer function. Finding the finest transfer function for this gadget enables us to prepare diverse practical undergraduate and graduate curricula.

The Moderating Effect of Religiosity on the Relationship between Attachment and Psychological Wellbeing in a Muslim-American Sample

Access: Use of this item is restricted to the UNT Community.
Date: August 2016
Creator: Khan, Arubah
Description: Although research on attachment theory has grown exponentially in the field of psychology, few studies exist that examine this theory among young Muslim-American adults, despite the fact that Muslim-Americans represent a significant and growing segment of the U.S. population. The first goal of the current study was to replicate the results of previous studies demonstrating a strong relationship between attachment and the selected wellbeing indicators of psychological symptoms and life satisfaction. The second goal of the proposed study was to examine the relationships among maternal attachment, Islamic religiosity, and psychological wellbeing. Findings provided partial support to the direct effects of attachment and religiosity variables on particular outcome variables but did not support the moderating effect of religiosity. High maternal Control was found to be predictive of less psychological distress, whereas both maternal control and care were found to be negatively associated with an interpersonal behaviors aspect of religiosity. In addition, those who endorsed practicing Islamic rituals were found to report less life satisfaction, and individuals who viewed the world through an Islamic lens reported higher psychological distress. Discussion on the findings, limitations of the study, future research directions, and counseling implications are addressed.

Description: Network security is a complex field that is handled by security professionals who need certain expertise and experience to configure security systems. With the ever increasing size of the networks, managing them is going to be a daunting task. What kind of solution can be used to generate effective security configurations by both security professionals and nonprofessionals alike? In this thesis, a web tool is developed to simplify the process of configuring security systems by translating direct human language input into meaningful, working security rules. These human language inputs yield the security rules that the individual wants to implement in their network. The human language input can be as simple as, "Block Facebook to my son's PC". This tool will translate these inputs into specific security rules and install the translated rules into security equipment such as virtualized Cisco FWSM network firewall, Netfilter host-based firewall, and Snort Network Intrusion Detection. This tool is implemented and tested in both a traditional network and a cloud environment. One thousand input policies were collected from various users such as staff from UNT departments' and health science, including individuals with network security background as well as students with a non-computer science background to analyze ...

Description: Peculiar Pairings: Texas Confederates and their Body Servants is an examination of the relationship between Texas Confederates and the slaves they brought with them during and after the American Civil War. The five chapter study seeks to make sense of the complex relationships shared by some Confederate masters and their black body servants in order to better understand the place of "black Confederates" in Civil War memory. This thesis begins with an examination of what kind of Texans brought body servants to war with them and the motivations they may have had for doing so. Chapter three explores the interactions between master and slave while on the march. Chapter four, the crux of the study, focuses on a number of examples that demonstrate the complex nature of the master slave relationship in a war time environment, and the effects of these relationships during the post-Civil War era.
