description: The fundamental interactions between two biologically and environmentally relevant metals, Zn2+ and Cd2+, complexed with water, crown ethers, and histidine are examined using a variety of experimental methods and quantum chemical calculations. Chapters 3 and 6 detail the first experimentally determined hydration energies for n = 6 - 10 for Zn2+(H2O)n and n = 3 - 11 for Cd2+(H2O)n measured using threshold collision-induced dissociation in a guided ion beam mass spectrometer. Kinetic energy dependent cross sections are obtained for each reactant and analyzed to yield 0 K threshold measurements for loss of one, two, and three water ligands after accounting for multiple collisions, kinetic shifts, and energy distributions. The threshold measurements are converted from 0 K to 298 K values to give the hydration enthalpies and free energies for sequentially losing one water from each complex. Theoretical geometry optimizations and single point energy calculations are performed on reactant and product complexes using several levels of theory and basis sets to obtain thermochemistry for comparison to experiment. The charge separation process, M2+(H2O)n - MOH+(H2O)m + H+(H2O)n-m-1, is also observed, analyzed, and discussed in detail in both Chapters 4 and 6 for M = Zn and Cd. In Chapter 5, complexes of Zn2+(H2O)n, where n = 6 - 12, are also examined using infrared multiple photon dissociation (IRMPD) spectroscopy, blackbody infrared radiative dissociation (BIRD), and theory for experimental determination of the coordination behavior of Zn2+. IRMPD spectroscopy experiments and theoretical calculations are also used in Chapter 7 to gain conformational insight into host-guest systems, namely Zn2+ and Cd2+ complexed with crown ethers (12-crown-4, 15-crown-5, and 18-crown-6). Finally, Chapter 8 examines the gas-phase structures of singly and doubly-charged complexes involving Zn and Cd with the amino acid histidine (His) as well as de-protonated His (His-H) using IRMPD spectroscopy.

Dictatorship is democracy: the persuasive power of performance, repetition, and silence in Arabic political speechmaking in Assad's Syria

description: This thesis is an analysis of performance, linguistic repetition, and silence in Syrian President Bashar al-Assad's March 30, 2011 speech to the People's Assembly given 2 weeks after riots erupted in the Syrian province of Deraa on March 15, 2011. Various types of repetition including syntactic parallelism, word strings, lexical repetition, and phonological and morphological repetition particular to Arabic syntax and its root and pattern system of morphology are analyzed along with manipulative silence and performance aspects of the speech. This examination reveals that these features were employed intentionally in order to support political strategies and have a certain degree of persuasive or influential power over speech receivers. The analysis also exposes some of the possible practical and/or ideological considerations specific to the Arab or Syrian context which seem to be motivating either specific instances of repetition and/or the overarching political strategies supported by repetition structures, such as a perception of the U.S. and Israel as colonial or imperial oppressors, the increasing significance of words such as "revolution", "people", etc., in the Arab world, Syrian Ba'ath Party ideologies, Arab culture and the concepts of "honor" and "shame", the preeminence of family in Arab culture, security concerns, Syria's societal heterogeneity, tactics related to limiting communications, and Syrian national understanding of previous crises and regime critics. The study of emotive speech such as repetition is particularly relevant in the Syrian case where political ideology largely precludes the use of mixed Arabic and/or religious speech in political speech-making. This study facilitates further studies of repetition in speechmaking for Arab political leaders. Future studies will be enhanced if researchers are able to precisely measure reactions of speech consumers.

Presynaptic neurons control postsynaptic GABAa receptor trafficking in Caenorhabditis elegans

description: Inhibitory neurotransmission is critical for regulating neuronal excitability. The main inhibitory neurotransmitter is gamma-aminobutyric acid (GABA). It acts predominantly at postsynaptic GABA(A) receptors. GABAA receptors are heteropentameric chloride ion channels. Receptor activation results in chloride influx, which rapidly reduces membrane excitability. Balance between inhibition and excitation is tightly regulated to ensure efficient neurotransmission. Significant reduction in GABA(A) receptor efficacy causes anxiety and epilepsy. GABA(A) receptor-agonists are the primary treatment for these disorders. Although regulation of these receptors plays a major role in controlling excitability, we understand very little about the physiological mechanisms underlying the development and maintenance of inhibitory synapses. Mammalian inhibitory synapses are difficult to study, in vivo, due to limited genetic accessibility as well as receptor heterogeneity. In contrast, Caenorhabditis elegans is well suited to study these synapses. Its nervous system is genetically accessible and its GABA (A) receptor is simple and uniform. It functions in bodywall muscles to promote muscle relaxation during locomotion. Normally, GABA (A) receptors are localized at synapses. We reasoned that if genes required for proper receptor trafficking were mutated, synaptic localization of these receptors would be lost. We performed a simple genetic screen to identify mutants with mislocalized receptors, and isolated mutants with intracellular accumulation of GABA (A) receptors in large organelles. One of these mutants carried a mutation in the unc-3 gene. UNC-3 acts in neurons, yet our phenotype is in muscles. To explain this conundrum, we hypothesized that presynaptic neurons control postsynaptic GABA(A) receptors. To test this hypothesis, we examined GABA(A) receptor localization in an axonal pathfinding mutant that removes innervation from postsynaptic cells. Normally these cells receive GABA and ACh innervation. In cells lacking both types of inputs, we observed UNC-49 accumulation in similar organelles. We identified these organelles as autophagosomes. Autophagosomes deliver cellular components to the lysosome for degradation. Selective restoration of either cholinergic or GABAergic innervation suppresses GABA(A) receptor autophagy; however, only GABAergic motor neurons induce receptor clustering. We conclude first that presynaptic terminals induce GABA(A) receptor cluster formation by independently regulating receptor localization and receptor stability and second, that autophagy is a novel degradative trafficking pathway for GABA(A) receptors.

Note. Dechambre (1997a) splits the species Cyclocephala carbonaria into a number of species, with C. carbonaria itself being restricted to Central America. According to this, South American specimens previously identified as C. carbonaria, such as those mentioned for Venezuela in Joly (1995: 171) and Moore et al. (2018b: 156) (the latter who simply copied from older publications), must thus belong to other species. Ratcliffe (2003: 99) suggests that more research needs to be done to establish if the South American specimens actually represent separate species or if they are merely intraspecific variations within C. carbonaria. The taxa which are described by Dechambre (1997a) and which are known to occur in the research area are C. boucheri and C. ergastuli. These are considered valid species by us and are included in this checklist.

Mother-infant interaction during bottle feeding

description: An exploratory study was undertaken for the purpose of identifying the mother and infant behaviors during the feeding-eating process, to produce a tool for recording such behavior, and to obtain information to serve as a basis for predicting which bottle feeding mothers will need outside assistance to successfully caring for their newborn infants.  The sample included six primiparas, one of who was unwed, and multiparas.  The mothers and infants were observed twice daily during their hospital stay beginning the first post-partum day and once at home.  The total minutes of observation for the entire sample was 1058; the range of total observation lengths for single mother-infant pairs was 56 minutes for the shortest period and 124 minutes for the longest.  The sample included two mothers with previous spontaneous abortions.  One mother had aborted three times and the other mother had aborted once.  The number of previous abortions correlated with more items than any other variable.  There were positive correlations with the touching categories of fingering and no contact (P < 0.01) indicating the lack of contact the mother had with her baby.  The care category of changing the diaper had a positive correlation (P > 0.01) indicating that the mother spent a relatively large amount of time during the feeding period in this activity.  Holding the bottle had a negative correlation significant at the 0.001 level; thus the mother with previous abortions tended to prop the bottle.  During ht observations the mother with three previous abortions was the only one who propped the bottle for long periods of time.  Mothers with previous abortions perceived their infants as crying much of the time (P < .0.001); and stated they were uncomfortable during the observations periods (P < 0.001).  The mother's response to the baby's crying and her secondary efforts to comfort the baby were both negatively correlated at the 0.05 level of significance, indicating that the mother used minimal levels of care to comfort the baby.  The study was too small to draw any decisive conclusion.  However, the mother's contact with  her infant, per perception of the amount of the infant crying, her method of handling the bottle, her initial and secondary responses to the infant's crying and her comfort during the feeding observations are areas which should provide fruitful areas for investigation  in the future.
Evaluation of critical personal samplers (COPS) for sampling sulfur hexafluoride
Creators: name: Petty, Carol L.
Publisher: name: University of Utah
Year: 2012

description: The goal of this study was to develop a new design for the Critical Orifice Personal Sampler (COPS) that is capable of sampling at constant flowrate (+/- 10% of the initial flowrates) for 8-hour periods.  By substituting an independent valve system for the septum and by coating the samplers with a perflex rubber, these goals were attained. The second goal of this study was to compare the COPS sampler's effectiveness with that obtained with gas sampling bags.  The COPS proved to be capable of achieving relatively high recoveries (89-102%) of sulfur hexa-fluoride when sampling from test atmospheres of 0.5X, l.OX, and 2.OX and the PEL (1000 ppm) at 53% relative humidity and ambient temperature of 25 degrees centigrade. The COPS is a very practical and useful application of the critical orifice principle.  It is felt that these samplers can become a much more viable and useful method for gas sampling.  The COPS, while providing similar results as the gas bag method, is less cumbersome to use, is versatile in application, and permits quick analysis. Since the lightweight COPS can be placed in a pocket or attached to a belt, the problems with workers wearing them are minimized.  These samplers can be used to sample for any gas in a relatively clean workplace environment. Gases presented collected on charcoal tubes, such as anesthetic gases, would be good candidates for method development in the future.  In those applications, such as the sampling and analysis of sulfur hexafluoride, where the analysis can be conducted by infrared analysis, field samples can be collected and analyzed on the same day. This provides the industrial hygienist with an efficient, effective tool to evaluate workplace exposures quickly and accurately without waiting weeks for samples to be returned from the laboratory.

description: During reconstructive and free tissue transfer surgeries it is often necessary to cut and reattach multiple vessels. The current method of vessel anastomosis is traditional hand suturing. The scope of this venture is to create a commercially available vascular coupling device (VCD) that would allow surgeons to quickly attach vessels together. The VCD is designed to increase reliability and reduce the amount of time spent on connecting two vessels. Hand suturing a vessel is time consuming (20-30 minutes) and difficult (requires a skilled surgeon). The method that has been developed can reduce the amount of time in the operating room by 75% and provides a superior anastomosis. In order to reach this level of improvement a set of installation tools was developed. These tools compliment the VCD and perform the necessary functions to consistently anastomise vessels. These tools were developed using laser machining techniques developed for this project. The laser manufacturing techniques allowed for the rapid development of the VCD and its supporting tools. With further development the VCD will become an important tool for the microsurgical community.

description: Spinal cord injury (SCI) is extremely debilitating to patients and costly to our healthcare system. Since it is an important contributor to mortality and morbidity, various therapeutic strategies have been investigated, either experimentally or clinically, to improve patients' quality of life. Studies utilizing pharmacological methods to mitigate the inhibitory components of the glial scar and facilitate axonal regeneration have been the primary experimental approaches in the field. However, the results are still not satisfactory. In this research, we aimed to tackle the issue from a novel perspective by developing cell derived, tissue engineered biomaterials that can be used in combination with other therapeutic approaches to improve the efficacy of current treatments. In this dissertation, a simple method to create either cellularized or acellular ECM biomaterial constructs is described. In particular, by utilizing patterned surface ligands, organized orientation can be introduced to the entire astrocyte derived construct morphologically and with regard to its associated matrix proteins, which mimics the native astrocyte framework within the spinal cord fiber tracts and provides these constructs the ability to guide axonal regeneration in vitro. In addition, meningeal fibroblast based biomaterial constructs are also developed taking advantage of the same engineering approach. It has been demonstrated that repairing damaged dura mater with allografts also benefits the regeneration process of the damaged spinal cord. In particular, acellular meningeal ECM constructs preserve a similar matrix protein profile as the native rat dura mater and support allogeneic meningeal cell adhesion and promote proliferation. The results suggest these engineered biomaterial constructs derived particularly from cells residing within tissue targeted for repair may carry appropriate tissue specific biological cues and hold therapeutic potentials for spinal cord injury repair as well as dual defect reconstruction.

Study of ordering and local atomic environments in iron-based magnetostrictive alloys

Subjects: Magnetostrictive alloys

Ordering

description: The α-phases of Fe-Ga and Fe-W alloys show large low field magnetostriction and the observed magnetostrictive behavior is sensitive to the solute content and thermal history. In order to improve understanding of magnetostriction, the first part of this work examines the influence of W substitution for Ga in Fe-Ga alloys and a more detailed examination of Fe-W alloys. The variation of magnetostriction coefficient λ100 with W substitution for Ga in various Fe-x at.% Ga alloys was examined. Fe-12.5 at.% Ga-2.5 at.% W, Fe-15 at.% Ga-2.5 at.% W and Fe-17.5 at.% Ga-2.5 at.% W single crystals were prepared by vertical Bridgman technique and annealed in the α-phase region followed by rapid water quenching. Increase of the Ga content in Fe-x at.% Ga-2.5 at.% W increased λ100 magnetostriction values up to 307 x 10-6 for 15 at.% Ga and further increase in Ga content decreased the magnetostriction value. Comparing the magnetostriction of Fe-Ga-W alloys to those of Fe-Ga alloys, the substitution of W for Ga caused more than a 7% drop in magnetostriction. The magnetostriction coefficients λ111 were also measured using of [220]- or [211]-oriented single crystals of Fe-12.5 at.% Ga-2.5 at.% W, Fe-3 at.% W, Fe-6 at.% W and Fe-7.5 at.% W alloys. The magnetostriction increases as the W content increased from 3 at.% to 7.5 at.% W. In the second part, the B2 and DO3 types of ordering were examined in annealed and quenched magnetostrictive Fe-27.5 at.% Ga single crystal and the presence of both B2 and DO3 ordered domains is demonstrated. The relative amounts of B2 phase domains increased with increasing depth up to about 100 um depth. After that, the volume ratio of B2 and DO3 domains showed little variation beyond this depth. In the third part, the extended x-ray fluorescence spectroscopy (EXAFS) studies of local atomic environment of Fe-27.5 at.% Ga, Fe-20 at.% Ga and Fe-15 at.% Ga single crystals were carried out. The study focused on the first and second nearest neighbors. The results obtained in the examination of Ga-Ga first nearest neighbor bond distance show a large positive increase after long-term annealing and the value of this positive strain increases as the Ga content increases. As the change of magnetostriction value with the changes in Ga content or thermal history follows the same tendency, it suggests a correlation between local lattice distortions to the material's magnetostrictive behavior.

Subjects: Carbon dioxide

description: A multiple-box model was designed to determine how anthropogenic, biological, and meteorological processes combine to produce diel cycles of carbon dioxide (CO2) concentrations within the urban Salt Lake Valley (uSLV). The model was forced by an anthropogenic CO2 emissions inventory, observed winds, sounding-derived mixing depths, and net biological flux estimates based on temperature, solar radiation, day of year, and ecosystem type. The model was validated using hourly CO2 data from a network of sensors around the uSLV for years 2005-2009. The model accounted for 53% of the observations on an hourly basis and accounted for 90-94% of the mean diel cycle of the observations depending on the season. Salt Lake Valley suffers from prolonged temperature inversions during the winter that trap pollutants and gases at the surface. The CO2 network (co2.utah.edu) was compared with the CO2 multiple-box model to determine whether the model could capture the main drivers of CO2 variability during the Persistent Cold Air Pool Study (PCAPS). Time-height analyses were performed to facilitate investigation and explanation of CO2 variability during PCAPS intensive observation periods (IOPs). The analyzed data included atmospheric soundings, CO2 network data, quasivertical CO2 profiles collected ascending by foot or vehicle, and laser-ceiliometer data.

Tetracyanoethylene

description: Several compounds in the metal-tetracyanoethylene (TCNE) family of molecule-based magnets have been studied. The first two are compounds that exhibit similar magnetic behavior as well as share an almost identical synthetic route, namely, MnII(TCNE)3/2(I3)1/2 and MnII(TCNE)I(OH2). They both have a critical temperature of 171 K and exhibit bulk ferrimagnetism. MnII(TCNE)3/2(I3)1/2 is the first known structure of a molecule based magnet to possess μ4-[TCNE]•- in all three dimensions. MnII(TCNE)3/2(I3)1/2 was also shown to exhibit a pressure-induced reversible enhancement of the critical temperature up to a maximum of 273 K. Suprisingly 2-D MnII(TCNE)I(OH2) has the same critical temperature as 3-D MnII(TCNE)3/2(I3)1/2 which may be attributed to significant dipolar interactions between the layers due to the relatively short interlayer separation. The next two compounds are the isostructural MII(TCNE)[C4(CN)8]1/2 (M = Mn, Fe). It was shown via detailed magnetic susceptibility measurements that they both possess an antiferromagnetic ground state with Tcs of 67 and 84 K, respectively. They also both exhibit a reversible ferri- or ferromagnetic pressureinduced magnetic transition. Finally, through a Mean Field (MF) theory analysis, it was shown that expressions that relate the exchange coupling to the critical temperature could be generated for several structure-types of the metal-TCNE family of materials. Using these expressions allowed for the estimation of the exchange coupling for several metal-TCNE compounds.
Computational study of edge stability and topological edge states of two-dimensional carbonic materials

Year: 2014
Subjects: Condensed matter physics
Materials science

description: In this dissertation, our aim is to contribute to the understanding of edge properties of two-dimensional (2D) carbonic materials, including graphene and organometallic frame-works. A set of modeling and simulations, using rst-principles density functional theory (DFT), tight-binding (TB) method, and molecular dynamics (MD) method, have been performed to (1) investigate the structural edge stability of graphene from both thermo-dynamic and kinetic points of view and (2) explore the existence of nontrivial electronic edge states, which carry nonzero topological invariant, in 2D organometallic frameworks. Specically, this dissertation comprises the following four chapters of topics: (1) chemical versus thermal folding of graphene edges; (2) quantum manifestations of graphene edge stress and edge instability; (3) prediction of a two-dimensional organic topological insulator; (4) prediction of a large gap at Chern band in a two-dimensional organic framework. Our work presented in the rst two chapters not only has explained certain experimental observations on graphene edges, but also has been conrmed by other researchers' ndings, both experimentally and theoretically. The studies shown in the last two chapters predict the existence of quantum spin Hall phase, a physical phenomenon that has been an exciting area of recent research in condensed matter physics, in 2D organometallic frameworks, a class of materials that are used to be mostly of interest to chemists. Therefore, we hope that these new ndings could lead to a marriage of condensed matter physics and organic chemistry to foster an interdisciplinary research eld, which will broaden the scientic and technology impact of topological materials.

Bias Reduced Peaks over Threshold Tail Estimation

description: Bias reduction in tail estimation has mainly been performed in case of Pareto-type models; see for instance Drees (1996), Peng (1998), Feuerverger and Hall (1999), Beirlant et al. (1999, 2002), Gomes and Martins (2002) and Caeiro et al. (2005, 2009). In that context, Beirlant et al. (2009) and Papastathopoulos and Tawn (2013) constructed distributional models that are based on second order rates of convergence for distributions of peaks over thresholds (POT). Such approach also allows to connect the tail and the bulk of the distribution. Bias reduction for all max-domains of attractions, i.e. without restricting to the Pareto-type case, received much less attention up to now. Here we extend the second-order refined POT approach started in Beirlant et al. (2009) providing a bias reduction technique for the classical generalized Pareto (GP) approximation for POTs. We consider parametric and nonparametric modelling of the second order component.

Specific cell-mediated immune recognition of penicillin conjugated to autologous albumin through amino or sulfhydryl moieties

Publisher: name: University of Utah
Year: 2012
Subjects: subject: Immunology
subject: FOS: Clinical medicine

description: To determine whether specific chemical linkages between proteins and haptens could be important in cell-mediated immune recognition of drugs, Penicillin-G (PG) was covalently conjugated to guinea pig albumin through amino (NH2) or sulfhydryl (SH) moieties.  Hapten densities ranged from four to one-hundred moles of PG per mole of albumin.  Slight differences in cell-mediated immunity to the conjugates were observed for different happen densities or doses of conjugate used for sensitization.  Guinea pigs sensitized with PG-albumin conjugates through amino group (PG-NH2) responded to the PG-NH2 conjugate in vivo (delayed skin test) and in vitro (Macrophage Migration Inhibition. MIF) but not to the PG-SH conjugate of albumin.  Animals sensitized of PG-SH responded to the PG-SH conjugate, and not to the PG-NH2 conjugate.  Penicilloylpolysysine (PPL) and PG were also tested for in vivo and in vitro efficacy to detect the hypersensitivity; PG alone did not result in any increase over baseline values and the inhibition of cellular migration form PG-NH2 sensitized animals challenged with PPL was not statistically significant.  In vitro dose response effect for the PG-NH2 conjugate suggest that the MIF assay in not as dose sensitive as lymphocyte transformation, where increase 3H-Thymidine uptake was seen with increase dose of antigen, while migration inhibition remained constant.
Simulating the diurnal cycle of the atmospheric boundary layer using large-eddy simulation with vertical adaptive mesh refinement

Large-eddy simulation

description: The diurnal evolution of the atmospheric boundary layer (ABL) plays an important role in weather, climate systems and particle and pollutant transport. Many numerical studies break the diurnal cycle up into its two primary components, the daytime convective period and the nocturnal stable period and only recently into the morning and evening transitions. This is especially prevalent in large-eddy simulation (LES) studies where simultaneously representing the diurnal cycle's two distinct regimes creates domain size and resolution problems. During the daytime, when positive buoyancy forces result in a rapidly growing boundary layer with highly energetic, large-scale turbulence, the domain size must be large enough to capture these motions. In contrast, at night negative buoyancy forces suppress turbulence resulting in a much lower boundary layer height and significant small-scale turbulent fluxes necessitating a finer grid resolution. While both regimes have been modeled successfully in independent simulations, most diurnal cycle LES studies under resolve the nocturnal boundary layer in order to capture the large-scale features of the convective boundary layer. Here, LES is combined with adaptive mesh refinement (AMR) in the vertical direction to achieve a more efficient and robust simulation of the diurnal ABL. Vertical grid spacing is adjusted with relocation-type refinement (r-refinement) to provide increased vertical resolution in the boundary layer without adding the computational overhead of additional points. Simulations of the 24-hour Wangara case (days 33/34) demonstrate that LES with AMR can successfully adapt in space and time to changing turbulent length scales, providing increased resolution within the boundary layer and improved results compared to simulations with a static grid and the same total number of grid points. During the daytime convective period, increased resolution in near surface and entrainment regions leads to better-represented first and second order statistics. During the nocturnal period, AMR simulations cluster grid points within the boundary layer improving the representation of stratified turbulence. While the representation of the nocturnal boundary layer is improved, results highlight the importance of employing sufficient resolution, especially in the horizontal direction, during highly stratified periods.

Cyclocephala chera Ratcliffe 2008: 226 (Guyana)
Distribution. Guyana: Ratcliffe 2008: 226; Moore et al. 2018b: 160. Suriname: MHCN - NEW COUN- TRY RECORD (Suriname, Para, Colakreek, (5°27′45″N, 55°13′45″W). 6/ 9-I-2013. A. J. Hielkema. On UV/HPL.); NZCS.
Note. Ratcliffe (2008: 226) describes Cyclocephala chera based on 10 female specimens from Guyana. In this description, Ratcliffe compares C. chera with C. complanata Burmeister, 1847 (p. 48), C. conspicua Sharp, 1877 (p. 135) and C. gregaria Heyne and Taschenberg, 1908 (p. 91), but not with C. undata (Olivier, 1789) (p. 80). We have collected a number of specimens in Suriname, including several males, which were identified as C. chera by Ratcliffe. After viewing photos of these specimens, Ponchel (Y. Ponchel, pers. comm. 2015) considers them synonymous with C. undata, which he says has a bicolored and a unicolored morph. Now that we have found male specimens of C. chera it seems prudent to compare both sexes of C. chera with those of both color morphs of C. undata.
