Medical comorbidity in the course of bipolar disorder.

Medical comorbidity in the course of bipolar disorder.

Access: Use of this item is restricted to the UNT Community.
Date: 2016-5
Creator: Smith, Patrick M
Description: Bipolar disorder is a serious illness affecting approximately 2-4% of the population and is one of the world’s leading causes of disability. In individuals with bipolar disorder, medical comorbidity associated with cardiovascular, respiratory and endocrine disorders is related to increased rates of mortality. Recent updates to multi-system inflammatory related conceptualizations of bipolar disorder focus on the unique power that medical illness and biological processes may play as factors associated with course and outcome in bipolar disorder. The current study examined medical comorbidity and its associations with various demographic and psychological variables in individuals with bipolar disorder, schizophrenia, and major depressive disorder with psychotic features followed for 10 years from their first hospital admission. When compared to an age, gender and race-matched control sample from the population, those with bipolar disorder had significantly higher medical comorbidity across a range of medical diagnoses both at 6 months and 10 years after first hospital admission. Ten years following initial hospitalization, individuals in all three diagnostic groups reported increased rates of diabetes (OR: 2.0 – 3.7), stroke (OR: 4.6 – 7.0) and asthma (OR: 1.9 - 3.1), and individuals with bipolar disorder reported increased rates of cancer (OR = 2.1). A number of psychological ...

Innovative Cold-Formed Steel Shear Walls with Corrugated Steel Sheathing

Innovative Cold-Formed Steel Shear Walls with Corrugated Steel Sheathing

Date: 2016-5
Creator: Mahdavian, Mahsa
Description: This thesis presents two major sections with the objective of introducing a new cold-formed steel (CFS) shear wall system with corrugated steel sheathings. The work shown herein includes the development of an optimal shear wall system as well as an optimal slit configuration for the CFS corrugated sheathings which result in a CFS shear wall with high ductility, high strength, high stiffness and overall high performance. The conclusion is based on the results of 36 full-scale shear wall tests performed in the structural laboratory of the University of North Texas. A variety of shear walls were the subject of this research to make further discussions and conclusions based on different sheathing materials, slit configurations, wall configurations, sheathing connection methods, wall dimensions, shear wall member thicknesses, and etc. The walls were subject to cyclic (CUREE protocol) lateral loading to study their deformations and structural performances. The optimal sit configuration for CFS shear walls with corrugated steel sheathings was found to be 12×2 in. vertical slits in 6 rows. The failure mode observed in this shear wall system was the connection failure between the sheathing and the framing members. Also, most of the shear walls tested displayed local buckling of the chord ...

Microstructural Phase Evolution In Laser Deposited Compositionally Graded Titanium-Chromium Alloys

Microstructural Phase Evolution In Laser Deposited Compositionally Graded Titanium-Chromium Alloys

Access: Use of this item is restricted to the UNT Community.
Date: 2016-5
Creator: Thomas, Jonova
Description: A compositionally graded Ti-xCr (10≤x≤30 wt%) alloy has been fabricated using Laser Engineered Net Shaping (LENSTM) to study the microstructural phase evolution along a compositional gradient in both as-deposited and heat treated conditions (1000°C followed by furnace cooling or air cooling). The alloys were characterized by SEM BSE imaging, XRD, EBSD, TEM and micro-hardness measurements to determine processing-structure-property relations. For the as-deposited alloy, α-Ti, β-Ti, and TiCr2 (C15 Laves) phases exist in varying phase fractions, which were influential in determining hardness values. With the furnace cooled alloy, there was more homogeneous nucleation of α phase throughout the sample with a larger phase fraction of TiCr2 resulting in increased hardness values. When compared to the air cooled alloy, there was absence of wide scale nucleation of α phase and formation of ω phase within the β phase due to the quicker cooling from elevated temperature. At lower concentrations of Cr, the kinetics resulted in a diffusionless phase transformation of ω phase with increased hardness and a lower phase fraction of TiCr2. In contrast at higher Cr concentrations, α phase separation reaction occurs where the β phase is spinodally decomposed to Cr solute-lean β1 and solute-rich β2 resulting in reduced hardness.

Performance Evaluation of UNT Apogee Stadium Wind Turbines

Performance Evaluation of UNT Apogee Stadium Wind Turbines

Date: 2016-5
Creator: Mccary, William Donald
Description: The following report chronicles the University of North Texas Wind Turbine Project at Apogee Stadium. The timeline of events will include the feasibility study conducted by and for the university, grant awards from the Texas State Energy Conservation Office to fund the project, and a three-year sample of real time performance data since installation. The purpose of this case study is to compare the energy generation estimates by various stakeholders to the measured energy generation using a new but uniform performance relationship. In order to optimize energy generation in wind turbine generator systems, the most common wind speeds measured at the site should also be the most efficient wind speeds at which the wind turbine can convert the kinetic energy in the wind into mechanical energy and ultimately electrical energy. The tool used to convey this relationship will be a figure plotting the wind speed profile against the efficiency curve of the wind turbine. Applying this relationship tool to the UNT Apogee Stadium wind turbines provided valuable results. The most common wind speeds at Apogee Stadium are not the most efficient wind speed for the turbine. Also, the most common wind speeds were near the lower limit of the wind ...

Commercial Diplomacy: The Berlin-Baghdad Railway and Its Peaceful Effects on Pre-World War I Anglo-German Relations

Commercial Diplomacy: The Berlin-Baghdad Railway and Its Peaceful Effects on Pre-World War I Anglo-German Relations

Date: 2016-5
Creator: Bukaty, Ryan Michael
Description: Slated as an economic outlet for Germany, the Baghdad Railway was designed to funnel political influence into the strategically viable regions of the Near East. The Railway was also designed to enrich Germany's coffers with natural resources with natural resources and trade with the Ottomans, their subjects, and their port cities... Over time, the Railway became the only significant route for Germany to reach its "place in the sun," and what began as an international enterprise escalated into a bid for diplomatic influence in the waning Ottoman Empire.

Mujeres sumisas, mujeres transgresoras en el siglo XIX español: una aproximacion a la obra de Francisca Navarro y Joaquina Garcia Balmaseda

Mujeres sumisas, mujeres transgresoras en el siglo XIX español: una aproximacion a la obra de Francisca Navarro y Joaquina Garcia Balmaseda

Date: 2016-5
Creator: Zaera, Isabel Maria
Description: This research discusses the changing role of women in Spanish society during the nineteenth century through the works of Francisca Navarro and Joaquina Garcia Balmaseda. The thesis shows the break with the traditional image of the "angel del hogar" and the gradual incorporation of the social changes affecting women which were reflected in the female protagonists of the comedies written by such playwrights. By reading theoretical texts of the emerging feminist theory and through analysis of the main female characters, this study examines the changes regarding the established canon and its own evolution within the nineteenth century, from the works of a pioneer like Francisca Navarro in the first third of the century to those of Joaquina Gracia Balmaseda towards the end of it.

Manhood in Spain: Feminine Perspectives of Masculinity in the Seventeenth Century

Manhood in Spain: Feminine Perspectives of Masculinity in the Seventeenth Century

Date: 2016-5
Creator: Gomez, Clemente
Description: The question of decline in the historiography of seventeenth-century Spain originally included socio-economic analyses that determined the decline of Spain was an economic recession. Eventually, the historiographical debate shifted to include cultural elements of seventeenth-century Spanish society. Gender within the context of decline provides further insight into how the deterioration of the Spanish economy and the deterioration of Spanish political power in Europe affected Spanish self-perception. The prolific Spanish women writers, in addition, featured their points of view on manhood in their works and created a model of masculinity known as virtuous masculinity. They expected Spanish men to perform their masculine duties as protectors and providers both in public and in private. Seventeenth-century decline influenced how women viewed masculinity. Their new model of masculinity was based on ideas that male authors had developed, but went further by emphasizing men treating their wives well.
