description: To test the hypothesis that sodium modifies calcium influx into the choroid plexus, the volume of distribution of ('45)Ca in rat choroid plexus was measured after various incubation periods in synthetic CSF solutions in which sodium and potassium concentrations were altered. The initial slope of the curve of ('45)Ca volume of distribution versus time is equal to the rate of calcium entrance into the choroid plexus tissue (I(,Ca)). The results indicate that calcium influx into the rat choroid plexus is carrier mediated with a I(,max) of 0.222 liter/kg wet tissue/min at 37(DEGREES)C and a Km equal to 0.275 mM. Sodium and potassium competitively inhibit calcium influx with Km's of 54.1 and 13.4 mM, respectively. Calcium influx is also correlated with the calculated membrane potential. The ('45)Ca volume of distribution at ten minutes, which is approximately equal to the steady state volume and reflects the amount of calcium in the cell cytoplasm, significantly correlates with choroid plexus water content. Total tissue water decreases as tissue calcium increases indicating the possibility of a negative feedback mechanism for calcium in regulating cell water and/or CSF secretion. Both amiloride (10('-3)M) and ouabain (10('-3)M) significantly (P < 0.05) inhibited calcium influx to 41% and 60% respectively of controls. Verapamil, a voltage-dependent calcium channel blocker, had no effect on calcium influx; this indicates that changes in calcium influx due to alterations in membrane potential caused by ouabain probably can not be attributed to opening or closing of voltage-dependent calcium channels. It is postulated that calcium, sodium and potassium compete for the inward arm of a cation/cation antiport system in the choroid plexus and that amiloride and ouabain influence calcium influx by directly affecting this membrane carrier. While not excluding membrane potential as a factor which affects calcium influx, extracellular sodium and potassium concentration appear to be dominant factors influencing calcium influx into the lateral ventricle rat choroid plexus.

description: Ever wonder how connections for light fittings and cable trays would perform safely under an earthquake event? Dr. Neupane investigated the seismic performance of small-sized fastenings in non-structural applications in large size crack width in concrete. He developed the first state-of-the-art experimental setup for testing fastening in concrete with crack opening and closing in the Southern Hemisphere. He has established the cracked concrete modelling approach through detailed finite element analysis. The findings contribute to the safety-critical applications of fasteners in the construction sector.

description: Hemodialysis vascular access, the interface between a dialysis patient and a dialysis machine, is quite literally the lifeblood of a patient's health. Vascular access dysfunction is the leading cause of hospitalization in hemodialysis patients. The occlusive growth of neointimal hyperplasia (NH) in expanded polytetrafluoroethylene (ePTFE) ringed grafts is the primary cause of failure. To further develop a proposed thermal ultrasound treatment to reduce or prevent NH in arteriovenous vascular grafts, the acoustic properties of ePTFE were studied in water and alcohol solutions. Previous reports of ePTFE acoustic properties are critiqued. It was found that the acoustic transmission and attenuation through ePTFE, and therefore the potential for an ultrasound-based therapy for NH, are heavily dependent on the medium in which the graft is immersed, suggesting that the acoustic properties of implanted grafts will change as grafts mature in vivo. The acoustic impedance and attenuation of water-soaked ePTFE were 0.478 ± 1.43 × 10-2 MRayl and 1.78 ± 0.111 Np/cm·MHz, respectively, while the acoustic impedance and attenuation of ePTFE in alcohol were 1.49 ± 0.149 MRayl and 0.77 ± 1.1 × 10-2 Np/cm·MHz, respectively. The use of focused ultrasound to heat implanted ringed ePTFE grafts was numerically modeled from 1.35- and 1.443-MHz transducers for in vitro geometries. Power deposition and heating, in turn, differed by an order of magnitude between various graft acoustic properties. Graft rings were predicted to be substantial absorbing and iv scattering features. In vitro phantom models were constructed: one with and one without thermocouples. At 1 W of acoustic power, the maximum temperature rise was 8˚ C. The thermocouple model containing a water-soaked graft did not experience heating in the far graft wall. The MRTI model confirmed that the graft rings are an absorbing/scattering feature. Heating was not prevented in the presence of water flow through the graft. Water was not heated significantly. Overall, results suggest ultrasound exposure can be used to generate temperature rises corresponding with the potential prevention or inhibition of NH in ringed ePTFE vascular grafts. A hybrid therapeutic/diagnostic transducer design with a therapeutic semi-annular array surrounding a diagnostic linear array is presented. Compared to a solid transducer of the same dimensions, there were only marginal aberrations in the focal plane. Numerical optimization of the element drive configuration indicated that the least distorted focal plane was produced by uniform phase and magnitude at each element.

description: The chemical investigation of Anonidium mannii root extract by column chromatography techniques led to the isolation of eight compounds among which two previously unreported compounds; a lanostane-type triterpene, lanosta-7,9(11),23-triene-3β,15α-diol 1 and an alkaloid, 9-hydroxy-8-methoxyphenanthridin-6(5H)-one 2 along with six known compounds: lanosta-7,9(11),24-triene-3β,21-diol 3, oxoanolobine 4, 3, 4-dihydroxybenzoic acid 5, stigmasterol 6, β-sitosterol 7 and 3-O-β-D-glucopyranosyl-β-stigmasterol 8. Their structures were established from spectral data, mainly HR-ESIMS, 1 D and 2 D NMR and by comparison with literature data. The crude root and stem bark extracts (AMR and AMB) and the isolated compounds (1–8) were tested against nine Gram-negative bacteria using rapid p-iodonitrotetrazolium chloride ≥97% (INT) microdilution technique. It was found that AMR, AMB and compound 5 were active against the nine tested bacteria with MIC values ranging from 64 to 1024 µg/mL. Compounds 1–4 had selective antibacterial activities whilst 6–8 were not active.

Development of the combined loading shear test method and shear strain measurement in the v-notched rail shear test

Year: 2012
Subjects: composites, extensometer, photoelasticity, shear modulus, shear strength, shear testing

description: Unique constraints are present when shear properties of orthotropic materials are desired, as they typically cannot be derived from tensile material properties like isotropic materials.  Specific test specimen geometry, and in some instances specimen layup, are required in order to obtain valid shear property data.  The V-Notched Rail Shear Test Method is one such test method developed to provide reliable shear test data for compo-site laminates.  However, specimens made from suitably high strength materials will slip prior to failure providing invalid results.  Previous work has been performed which im-proves on this test method by altering the specimen dimensions and fixture design in or-der to prevent slipping.  Changes made to the fixture introduced another load path into the specimen, which can influence the stress state within the specimen.  The current work looks at several aspects of the new Combined Loading Shear test fixture and how they affect the stress and strain state, as well as the measured shear strength.  Photoelastic test-ing is performed to validate numerical models and to investigate the strain state in several different specimen layups as a result of the fixture changes. Accurate shear strain measurement is required when determining the shear modu-lus of a material.  Bonded strain gauges are often used when strain measurements are re-quired; however, extensometers can provide the same functionality as strain gauges and have the advantage of being reusable.  Extensometers are typically application specific and require careful consideration with regards to attachment and the region where exten-sion is measured.  The current study proposes a shear extensometer for a V-Notched Rail Shear or Combined Loading Shear test specimen.  A mechanics of materials model is used to calculate the shear strain in the specimen based on the relative displacement of a discrete set of points on the specimen face.  Numerical simulations were performed to determine the points on the specimen face which would yield the most accurate measure of the in-plane shear modulus.  A prototype device is tested using carbon/epoxy, glass/epoxy, and Kevlar/epoxy cross-ply laminates and the data from the extensometer are compared to data from bonded strain gauges to validate the extensometer.

description: Fire is an extreme event that can lead to failure of structural components and potentially collapse of the structural system or sub-systems. Currently, there are no comprehensive, research-based methodologies for performance-based fire structural design (PBFSD) of composite wall-to-floor connections subjected to gravity loads and realistic fire scenarios. The existing studies primarily focus on the performance of simple shear connections to steel columns, and lack approaches for structural design of floor systems and their connections to walls (wall-to-floor connections) at elevated temperatures. This study addresses the need for evaluating the performance of composite floor systems and composite wall-to-floor connections under fire loading and developing research-based approaches to conduct performance-based structural design of these systems at elevated temperatures.This study aims to give a simpler design method for shear tab and single angle shear connections at elevated temperatures by specifying retention factors for steel yield strength, ultimate strength, bolt material strength, and weld metal strength at elevated temperatures. The connection limit state equations specified in AISC Specifications are modified to incorporate these factors for higher temperatures. Additionally, an archetype building is designed and one floor system is evaluated using Finite Element Analysis (FEA) to assess the robustness of the structure and its resistance to collapse using PBFSD.It also discusses the application of fire protection materials for steel members to resist fire scenarios for specified durations. Various fire scenarios, including ventilation-controlled and fuel-controlled fires were evaluated to assess localized behavior at the connection points and the overall behavior of the structural compartment. The FE analyses included various fire scenarios, compartment locations (interior, edge, or middle), and fire protection scenarios (2-hour rating fire protection, or no fire protection on interior beams). The composite floor system is evaluated for a combination of these scenarios under fire and gravity loading.Through this study, a comprehensive analysis of the behavior of composite floors systems and associated connections in SpeedCore Wall Systems (C-PSW/CF) under fire loading is achieved.

description: The focus of this dissertation is to explore novel effects in metal nanofilms, particularly, the quantum size effect (QSE) and strain effect, through the methodology of first-principles density functional theory (DFT) calculations. The QSE has already been shown to affect many properties of metal nanofilms, such as surface energy, work function, and even superconducting transition temperature. Based on the extensive DFT calculations that I carried out in the last five years, we further demonstrate that several new properties of metal nanofilms, including edge/surface stress, elastic constants, and adatom-adatom binding energy can also be modulated by QSE to exhibit strong thickness dependence. Specifically, this dissertation includes the following five chapters of topics: ( 1 ) interplay between strain effect and quantum size effect in metal nanofilm; (2 ) quantum manifestation of elastic constants in nanostructures; (3) QSE on adatom-adatom binding energy and island nucleation; (4) quantum manifestations of graphene edge stress and edge instability; (5) bistability of nanoscale islands induced by anisotropic stress. Overall, my dissertation research not only has explained a number of puzzling experimental observations and resolved some existing controversies, but also made some interesting theoretical predictions in novel quantum aspects of thin film growth and nanomechanics. It is my hope that these studies will further our fundamental understanding of QSE and strain effect in metal nanofilms, with broader implications in other low-dimensional nanostructures as well as in potential technological applications of nanostructures.
Randomized trial of reduced physical activity and increased rest in the prevention of pregnancy-induced hypertension

description: The purpose of this investigation was to test the value of encouraging increased rest and reduced physical activity in preventing pregnancy-induced hypertension and selected complications of the disease.  The supine pressor test was used to identify women at risk of developing pregnancy-induced hypertension.  Women with positive tests were randomly assigned either to a control or treatment group.  Treatment consisted of outpatient management using reduced activity and increased rest al long as the subjects remained normotensive.  Following delivery and discharge from the hospital, antepartum and hospital records of the subjects were evaluated for the presence of pregnancy-induced hypertension, and other selected complications of the disease.  This investigation was unable to demonstrate any effect of encouraging increased rest and reduced physical activity on the development of pregnancy-induced hypertension and its complications.  However, this research suffered from inadequate sample size, lack of control over the independent variables, and high incidence of false positive supine pressor tests.  The supine pressor test was found to be capable of discriminating between women who are more, and less likely to develop pregnancy-induced hypertension.  Its predictive ability can be enhanced by combining the test with the mean arterial pressure.  There is evidence that by correcting for hydrostatic pressure changes during performance of the test, the accuracy of the supine pressor test could be improved.  Women with a history or potential or renal disease and women who develop transient hypertension to not appear to contribute disproportionately to the incidence of false positive or negative tests.  The supine pressor test does not appear to be useful screening test for intrauterine growth retardation.  Intrauterine growth retardation was found to be associated not only with diastolic hypertension with proteinuria, but also with diastolic hypertension alone.

description: The reconversion years after World War II were very  important in the history of American labor. During this  period of economic readjustment many strikes occured.  The last of the major industrial conflicts was in the  bituminous coal industry. This strike in 194& finally  led to government seizure of the mines and government  operation continued for thirteen months. As government  operation continued a number of conflicts arose between  the government and the United Mine Workers. These revolved  around the problem of the rights of and the re*  strictions on workers in seized industries. The United  Mine Workers tried, unsuccessfully, to maintain union  rights, applicable in private enterprise, as government  employees. The result was the revival into law of the  labor injunction and the later restrictions on union  activities contained in the Taft-Hartley Act.  Another development of the conflict was the handling  of union demands for fringe benefits. The major  United Mine Workers requests in 1946 and 1947 were for  fringe benefits: mine safety regulation and funds for  miners8 welfare. It turned out that neither the government  nor the mine owners knew the ramifications, both economic and social, of these proposals,, In both contracts,  in 1946 and 1947? the union received major  concessions in these areas, and has led the way in  the American labor movement toward achieving increased  benefits, outside of wages and hours, for its members.

Railroad employee injuries

description: Slips, trips and falls are responsible for a major portion of occupational  injuries in industry. The U.S Department of Labor reported that the number of fatal  falls in 2007 was 835. an increase of 39 % since 1992. The increase of fatal fall  injures was mainly of falls on the same level. The Railroad Safety Statistics showed  that ground, ballast, or floor were principal causes of over one half of all severe  injuries. Railroad workers who work mainly on ballast represent less than 10% of  the total population of railroad employees; however, they experience 28% of  reportable injuries and 42% of the days absent from work for all railroad employees.  The main objective of this study was to investigate how walking on different  ballast types influences the probability of a trip or fall. Surface orientation (Level  and Sloped) was also investigated to identify factors that may increase the likelihood  of a trip/fall.  Ten healthy male subjects tested six combinations of two slope orientations  (level and sloped) and three surface types (flat surface, large ballast, and small ballast).  The two types of ballast used in this research were both crushed rock. The large  ballast had a diameter of between 2.5 - 5.5 cm and the small ballast had a diameter of  between 1 . 1 - 2.7 cm.  The current study provides evidence that there is a relationship between  walking on different surface conditions and gait patterns and that these changes in gait  pattern could result in additional fatigue. Walking on large and small ballast  significantly increased heel and toe clearance compared to walking on a hard. Hal  surface. After walking on large and/or small ballast for a long lime, fatigue may  affect a person's lower extremities so that heel/toe clearance is not met. This could  ultimately lead to catching ballast with the heel or toe and the initiation of a trip  induced fall.  It is recommended that employers provide a working environment to: I)  control working time on larger ballast. 2) train workers about the importance of being  aware of the walking surface and the potential increase in trip/fall likelihood when  fatigued 3) provide periodic rest breaks to minimize fatigue and provide opportunity  for rest and recovery.

description: Modeling induced polarization (IP) phenomena is important for developing effective methods for remote sensing of subsurface geology. Two resistivity relaxation models have been developed to describe the IP effect. The Cole-Cole model was formulated empirically more than 50 years ago. A few of the parameters within this model are able to account for IP phenomena and can give useful information for the analysis of bulk rock formations. Forward modeling using synthetic data is done to analyze the three empirical variables of the Cole-Cole model. These empirical variables are the decay coefficient (C), chargeability (m),  and the time constant (  ). The generalized effective-medium theory of induced polarization (GEMTIP) model is another resistivity model similar to the Cole-Cole model. However, the GEMTIP model attempts to characterize heterogeneous, multiphase, polarized media using the effective-medium approach and can consider many more useful parameters than the Cole-Cole model. Forward modeling is also done with synthetic data to analyze four GEMTIP parameters. These parameters are the surface polarizability coefficient (?), the decay coefficient (C), the inclusion volume fraction (f), and the ellipticity of the inclusions  (E). Complex resistivity data was collected on several rock samples that contain disseminated sulfides, which are conducive to IP phenomena.

description: Family leisure often occurs in ways that do not result in families accruing the suggested benefits of leisure. This study sought to examine the interactions that occur  during family leisure and how such interactions might influence desired outcomes. Research was conducted from a systems perspective that looked at whole family interactions. Methods for this research included creating a literature review based model of family leisure, gathering interview data from three families, creating models for each family's leisure, and running simulations to examine how changes among elements might impact outcomes. This research found some support for interactions in the initial literature review model, but not for the entire model. Rather, results indicated that families may experience unique elements during their leisure, but that the need to negotiate constraints, increase focused interactions, and decrease fragmented interactions were constant among all families in this study. These findings resulted in a simplified model of family leisure. Finally, simulations provided some insight into the influence specific elements may have on family leisure. The study ended with a simplified model of family leisure, recommendations for practitioners, and suggestions for future research.

description: Recent discoveries demonstrate that Campanian dinosaur assemblages across the western North American subcontinent (Laramidia) exhibit basin-scale endemism, with each sedimentary basin possessing its own unique assemblage, and an apparent higher-level biogeographic boundary between northern and southern Laramidia. Subsequently, during the Maastrichtian, most taxa are present in multiple basins, with some forms supporting the presence of distinct northern/southern provinces, whereas others are more cosmopolitan. Despite these dinosaur biogeographic data, little attention has been paid to other vertebrate groups. To test these biogeographic hypotheses, I examined the alpha taxonomy, evolution, and paleobiogeography of the paracryptodiran turtle clade Baenidae using a newly-generated species-level phylogeny. Baenids were one of the most diverse and abundant turtle clades during the Late Cretaceous, are restricted to North America, and have a well-sampled fossil record, making them an ideal study system for examining Laramidian biogeography. I first assessed the taxonomic affinities of newly discovered baenid turtles from the Upper Cretaceous (Campanian) Kaiparowits Formation of southern Utah. I found that at least five distinct baenid species inhabited the Kaiparowits Basin during the Campanian. These taxa include Denazinemys nodosa, previously known from Texas and New Mexico, Boremys grandis, previously known from New Mexico only, and three new iv taxa that appear to have been endemic to southern Utah. These newly described taxa include two new species of Neurankylus and a morphologically unique pig-nosed taxon. Using new morphologic data from the Kaiparowits specimens, I conducted a comprehensive phylogenetic analysis on the clade, utilizing 106 characters and 32 ingroup taxa. Based on occurrences alone, Campanian baenid assemblages display distinct northern and southern provinces with no taxonomic overlap. To investigate the evolutionary patterns of this biogeographic signal, I applied a dispersal-extinction-cladogenesis model to the strict consensus tree and three randomly selected most parsimonious trees from my phylogenetic analysis. This study reveals that the ancestral ranges for basal baenid branches were cosmopolitan across either Laramidia or all of North America. More derived baenids (i.e., subclade Baenodda) possessed ancestral ranges in the area of Montana, Wyoming, and the Dakotas, and the analysis reconstructs multiple individual lineages then dispersing to southern Laramidia and Alberta.

description: The premise of this research is to determine when the end of rentierism will occur in the Kingdom of Saudi Arabia as well as what actions the government is taking to prepare for it. After compiling population growth, domestic consumption demand, and depreciating oil production into four separate future predictive scenarios, the results are that the end of rentierism will occur between 2022-2033 in Saudi Arabia. Analysis on the social, economic, and political landscapes was conducted to illustrate the current social and economic obligations that the government currently has. Alternatives to petroleum were analyzed, resulting in the finding that there are no viable natural resource alternatives to oil in order to maintain rentierism. The primary obstacles to preparing for the death of rentierism were found to be the extreme dissent within and between the House of Saud and the religious establishment, and the lack of stated goals with timelines and accountability for implementing economic diversification goals.
Parental modeling and adolescents' quality of experience

Adolescence

description: Adolescent development is affected by a teenager's quality of experience and  ability to respond to anxiety or boredom. Teens who have difficulty self-regulating  anxiety or boredom can struggle in school and in other areas of life. On the other hand,  teens who are able to cultivate more optimal engagement or flow are more likely to  develop their skills and have a better quality of life. Using data from 88 parent-child  dyads, and drawing on a modeling perspective as outlined in Bandura's Social Learning  Theory, the present study explored whether adolescent students who had a highly  engaged parental model were more likely to experience optimal engagement themselves.  Students were placed into one of two groups based on their parents' responses to  questions about self-regulatory style and quality of experience. These two student groups  were then compared using data from student surveys and the Experiential Sampling  Method-a research technique using programmed watches to prompt repeated selfreports  in natural contexts. Results indicate that students with a same-sex parent who  modeled high engagement reported more flow, less boredom, and less anxiety during a  school day than students without such a parental model. These findings are discussed in  terms of their implications for adolescent development and future research on parental  modeling.

Comparison of the cyclone and the horizontal elutriator for sampling respirable dust in a Utah coal mine

Year: 2012
Subjects: Coal mines and mining

description: A field investigation was conducted comparing proposed optimizing parameters for estimating respirable dust according to British Medical Research Council (BMRC) criteria using a Dorr-Oliver 10 mm cyclone and the parameters presently applied under federal law.  Side-by-side samples were collected in an underground Utah coal mine with 10 mm cyclones at 1.2, 1.4, 1.7, and 2.0 liters per minute (£pm) and an MRE horizontal elutriator.  The cyclone concentrations were statistically compared to the elutriator concentrations.  Random errors were too large to conclusively confirm or disprove the cyclone optimization theory.  The data demonstrated trends which are more supportive of the 1.2 ilpm, k = 0.91 optimizing criteria than the 2.0 ilpm, k = 1.38 criteria outlined under the Federal Coal Mine Health and Safety Act.  The results of this study will be useful in planning more in-depth future research.

description: The similar timescales and field relationships in magmatic systems suggest common processes, whether the system is mineralized or has associated volcanism. Though often overlooked because of alteration and their relatively small size, the magmatic-hydrothermal environment may prove key to a holistic model of magmatic systems. Seven age distributions from the Morgan Creek pluton were determined by LA MC-ICP-MS U-Pb zircon analysis and the ages of six molybdenite samples from the adjacent Pine Creek tungsten skarn were determined by Re-Os molybdenite analysis to examine the timing, duration, and evolution of a mineralized magmatic system. The molybdenite ages range from 91.0 to 107.2 Ma. Ages for three of the six samples are identical within error (±0.5 Ma) at ~94 Ma. Ages of 91.0 and ~94 Ma may represent distinct mineralizing events, whereas the oldest two ages from disseminated molybdenite in the skarn may indicate disturbance of the Re-Os system. The U-Pb data show dominant populations at ~96-98 and ~94 Ma. The main facies of the Morgan Creek pluton, comprising over 95% of the pluton, can be divided into three groups based on mafic mineral abundance and whole rock major and trace element geochemistry. Major element geochemistry is very similar to that of plutons in nearby intrusive suites. However, trace element geochemistry (Ba, Rb, Sr, Zr, and REE) suggest a distinct genesis from typical intrusive suite magmas. Trace element models suggest the magmas that formed the Morgan Creek pluton were derived from partial melting of upper crustal rocks. The Morgan Creek pluton was emplaced either as a single batch of magma, or through multiple rapid pulses that led to a single magma body. Fractional crystallization of a relatively homogenous volume of magma led to the chemical variations seen within the pluton. The age and compositional data show that the Morgan Creek pluton is not a part of the Lake Edison Granodiorite, as was previously interpreted. Instead, the Morgan Creek pluton represents an early stage of the John Muir Intrusive Suite, possibly correlative with the Basin Mountain pluton which is commonly interpreted to be part of the Lake Edison Granodiorite.
