The Physiological Effects and Projected Outcomes of Urbanization and Pollution on Reptiles

Research regarding urbanization and its relationship with population fluctuations and physiological responses in animals has been assessed through a multitude of studies involving stress hormone changes, white blood cell counts and other physical and behavioral changes. The scope of this paper emphasizes the explanation of urbanization, the physiological and anatomical impact it has made on reptiles, and the projected outcomes urbanization will have in the future. Some questions are brought up in this paper to serve as a basic overview of what will be learned about urbanization and pollution. In order to provide background information, my research has been conducted and many studies were summarized. Even though there have been studies done that provide an overview for this topic, there should be future research conducted to determine exact ways urbanization can be limited to help protect the class of reptiles, along with all living organisms, from the harmful effects of urbanization and pollution.Kayla SiddellHonors DiplomaHonors CollegeCunningham Memorial Library, Terre Haute, Indiana State UniversityUndergraduateTitle from document title page.

The Savings and Loan Debacle Twenty-Five Years Later: A Critical Appraisal, Interest-Group Theory Re-Examination, and Final Closing of the Book

August 9, 2014 marked the twenty-fifth anniversary of the Financial Institutions Reform, Recovery, and Enforcement Act (FIRREA) of 1989. FIRREA was to “clean up” the savings and loan debacle of the 1980s. Articles, books, symposia, and papers written in the wake of the debacle, popular media and mainstream financial economists each provided detailed explanations. This paper analyzes and rejects those explanations in favor of an alternative based on interest-group theory and a chain of causes in legislative history where market interventions led to unintended consequences, more interventions and more unintended consequences until no more interventions were possible

Developing a Strategy of Worship for Evangelical Believers Born from 1945 to 1955

This project researched the need for developing a worship ministry strategically designed to meet the cultural, spiritual, musical, and emotional demands of early senior adults, those born from 1945 to 1955. The research question is, How can the evangelical church meet the worship needs of her members born from 1945 to 1955

Evolution of the Resonance and Incommensurate Spin Fluctuations in Superconducting YBa₂Cu₃O₆₊ₓ

Polarized and unpolarized neutron triple-axis spectrometry was used to study the dynamical magnetic susceptibility Χ″(q, ω) as a function of energy (ℏ ω) and wave vector (q) in a wide temperature range for the bilayer superconductor YBa2Cu3O6+x with oxygen concentrations, x, of 0.45, 0.5, 0.6, 0.7, 0.8, 0.93, and 0.95. The most prominent features in the magnetic spectra include a spin gap in the superconducting state, a pseudogap in the normal state, the much-discussed resonance, and incommensurate spin fluctuations below the resonance. We establish the doping dependence of the spin gap in the superconducting state, the resonance energy, and the incommensurability of the spin fluctuations. The magnitude of the spin gap (Esg) up to the optimal doping is proportional to the superconducting transition temperature Tc with Esg/kBTc = 3.8. The resonance, which exists exclusively below Tc for highly doped YBa2Cu3O6+x with x = 0.93 and 0.95, appears above Tc for underdoped compounds with x≤0.8. The resonance energy (Er) also scales with kBTc, but saturates at Er≈40 meV for x close to 0.93. The incommensurate spin fluctuations at energies below the resonance have structures similar to that of the single-layer superconducting La2-xSrxCuO4. However, there are also important differences. While the incommensurability (δ) of the spin fluctuations in La2-xSrxCuO4 is proportional to Tc for the entire hole-doping range up to the optimal value, the incommensurability in YBa2Cu3O6+x increases with Tc for low-oxygen doping and saturates to δ = 0.1 for x≥0.6. In addition, the incommensurability decreases with increasing energy close to the resonance. Finally, the incommensurate spin fluctuations appear above Tc in underdoped compounds with x≤0.6 but for highly doped materials they are only observed below Tc. We discuss in detail the procedure used for separating the magnetic scattering from phonon and other spurious effects. In the comparison of our experimental results with various microscopic theoretical models, particular emphasis was made to address the similarities and differences in the spin fluctuations of the two most studied superconductors. Finally, we briefly mention recent magnetic-field-dependent studies of the spin fluctuations and discuss their relevance in understanding the microscopic origin of the resonance

Apparatus comprising an optical gain device, and method of producing the device

Disclosed is apparatus comprising an optically pumped optical gain device that comprises a rare earth (RE)-doped planar waveguide with non-uniform dopant distribution in the core of the waveguide. The RE ions are advantageously distributed such that the ions are concentrated in a core region in which the mode intensity of both signal radiation and pump radiation is relatively high. In preferred embodiments of a single mode planar waveguide according to the invention the RE ions are substantially concentrated in the central core region. A method of making the disclosed apparatus is also disclosed. The method involves implantation of RE ions into the core region.Published versio

Investigation of congestive heart failure in beef cattle in a feedyard at a moderate altitude in western Nebraska

Right-sided congestive heart failure (brisket disease) commonly occurs in cattle raised at elevations \u3e2,500– 3,500 m. We investigated clinical cases resembling brisket disease at a western Nebraska feedyard at a moderate altitude (1,369 m). Over a 15-mo period (2009–2010), we examined 17 cases (16 steers and 1 heifer), all purebred Angus. All animals had clinical right-sided heart failure: brisket and ventral abdominal edema, and severe chronic passive congestion of the liver. Gross examination confirmed right ventricular hypertrophy (left ventricle plus septum: right ventricle weight ratio mean: 1.33 vs. 2.8–4.0 reference interval). Microscopically, all 17 cases had interstitial fibrosis (mean score: 2.4 ± 0.8) and 6 had replacement fibrosis of the right ventricle, whereas 14 had interstitial fibrosis (mean score: 1.2 ± 0.2) and 0 had replacement fibrosis of the left ventricle. Lesions of arteriosclerosis were seen in 9 of 16 cases in 51 of 571 (8.9%) right ventricular coronary arteries, and in 10 of 16 cases in 52 of 366 (14.2%) left ventricular coronary arteries. The probability of coronary arteriosclerosis was greater in papillary ventricular muscle (OR = 11.3; p \u3c 0.0001), left ventricle (OR = 4.8; p \u3c 0.0001), and larger arteries (OR = 1.01; p \u3c 0.0001). Pulmonary arteries and arterioles had lesions compatible with hypoxia-induced pulmonary hypertension. We hypothesize that moderate hypobaric conditions significantly contributed to disease in cattle genetically predisposed to hypoxia-induced pulmonary hypertension. Adiposity, coronary arteriosclerosis, and left ventricular fibrosis may have contributed to the condition; however, the cattle died prior to development of advanced obesity

Determination of Ideal Broth Formulations Needed to Prepare Hydrous Hafnium Oxide Microspheres via the Internal Gelation Process

A simple test-tube methodology was used to determine optimum process parameters for preparing hydrous hafnium oxide microspheres by the internal gelation process. Broth formulations of hafnyl chloride [HfOCl{sub 2}], hexamethylenetetramine, and urea were found that can be used to prepare hydrous hafnium oxide gel spheres in the temperature range of 70-90 C. A few gel-forming runs were made in which microspheres were prepared with some of these formulations in order to equate the test-tube gelation times with actual gelation times. These preparations confirmed that the test-tube methodology is reliable for determining the ideal broths
