description: Biomedical implantable devices have been developed for both research and clinical applications, to stimulate and record physiological signals in vivo. Chronic use of biomedical devices with thin-film-based encapsulation in large scale is impeded by their lack of long-term functionality and stability. Biostable, biocompatible, conformal, and electrically insulating coatings that sustain chronic implantation are essential for chip-scale implantable electronic systems. Even though many materials have been studied to for this purpose, to date, no encapsulation method has been thoroughly characterized or qualified as a broadly applicable long-term hermetic encapsulation for biomedical implantable devices. In this work, atomic layer deposited Al2O3 and Parylene C bi-layer was investigated as encapsulation for biomedical devices. The combination of ALD Al2O3 and CVD Parylene C encapsulation extended the lifetime of coated interdigitated electrodes (IDEs) to up to 72 months (to date) with low leakage current of ~ 15 pA. The long lifetime was achieved by significantly reducing moisture permeation due to the ALD Al2O3 layer. Moreover, the bi-layer encapsulation separates the permeated moisture (mostly at the Al2O3 and Parylene interface) from the surface contaminants (mostly at the device and Al2O3 interface), preventing the formation of localized electrolyte through condensation. Al2O3 works as an inner moisture barrier and Parylene works as an external ion barrier, preventing contact of AI2O3 with liquid water, and slowing the kinetics of alumina corrosion. Selective removal of encapsulation materials is required to expose the active sites for interacting with physiological environment. A self-aligned mask process with three steps was developed to expose active sites, composed of laser ablation, oxygen plasma etching, and BOE etching. Al2O3 layer was found to prevent the formation of microcracks in the iridium oxide film during laser ablation. Bi-layer encapsulated iridium oxide had higher charge injection capacity and similar electrochemical impedance compared with Parylene C coated iridium oxide film after deinsulation. The Al2O3 and Parylene C bi-layer encapsulation was applied to Utah electrode array (UEA)-based neural interfaces to study its long-term performance. The median tip impedance of the bi-layer encapsulated wired Utah electrode array increased slowly during the 960 days of equivalent soak testing at 37 °C. Impedance for Parylene coated UEA dropped 50% to 75% within 6 months. In addition, bi-layer coated fully integrated Utah array-based wireless neural interfaces had stable power-up frequencies at ~910 MHz and constant RF signal strength of -50 dBm during the 1044 days of equivalent soaking time at 37 °C. This is much longer than lifetime achieved with Parylene C coating, which was about one year at room temperature.

description: The wide use of zinc and the exhaustion of traditional sulfide zinc resources provide the motivation to consider oxide zinc mineral resources. Smithsonite is the most abundant nosulfide zinc mineral but it is hard to be separated from other carbonate minerals by flotation techniques. Therefore, potassium lauryl phosphate was evaluated as a new flotation collector with respect to physicochemical aspects. For comparison, dodecylamine was also considered as a common collector reported in the literature for smithsonite flotation. Crystal structure analysis results indicate that the distances between zinc atoms on the smithsonite cleavage plane are smaller than the distances between calcium atoms on the calcite cleavage plane. The carbonate phase was the only predominant solid phase over all pH values in an open system, both for smithsonite and calcite. Zeta potential measurements suggest that potassium lauryl phosphate adsorbs on both smithsonite and calcite. An obvious difference between contact angles for smithsonite and calcite was observed with potassium lauryl phosphate as the collector from pH 6 to 9. On the other hand, there is no great difference between smithsonite and calcite contact angles with dodecylamine as the collector for all pH values studied. The flotation response shows an obvious difference between the flotation recovery of smithsonite and that of calcite using potassium lauryl phosphate as a collector for the pH 5 to pH 10 region. However, when dodecylamine was used as a collector, no significant difference in smithsonite and calcite flotation recovery was observed at any pH value. The adsorption states of collectors were described from sum frequency generation experiments. It is suggested that with potassium lauryl phosphate as the collector a closely packed layer was formed on the smithsonite surface from pH 3 until pH 9. On the other hand, the adsorption density on the calcite surface decreases and disorder of the interface increases from pH 4. The SFG spectra also suggested that the adsorption of dodecylamine started from pH 10 for both smithsonite and calcite. These findings suggest that potassium lauryl phosphate will be an effective collector for the flotation recovery of smithsonite from oxide zinc ores.
Heat transfer analysis of thermosiphons and U-tube ground source heat pumps

description: Ground source thermal energy transport systems have the potential to improve the efficiency of space heating. Two such systems, a thermosiphon and a vertical U-tube system, were installed in a housing unit in Park City, Utah with the aim of assessing performance. From temperature measurements, the heating Coefficient of Performance (COP) for the U-tube system was determined to be around 3. When taking into consideration only space heating, because of the poor performance of the U-tube system and the relatively inexpensive cost of natural gas, the high installation cost of this particular U-tube GSHP will not be recouped in energy cost savings. COP was not used to assess the thermosiphon, but the heat transfer rate per unit length associated with the thermosiphon was found to be approximately 2.3 times greater than that of the U-tube system. Transient temperature measurements led to the development of a conceptual heat transfer model that described the convective heat transfer between flowing groundwater and the thermal grout sealing each piping network. Using this model, a method was developed to infer the convective heat transfer coefficient of each system directly from temperature measurements along the outside of each piping network without directly measuring groundwater velocity. From this method, the heat transfer coefficient for the U-tube was accurately found to be between 8 and 14.4 W/m2-K.

description: The purpose of this study was to determine if play therapy using injection equipment and doll play would reduce measured anxiety in preschool children when they received injections.  Little controlled nursing research has been conducted prior to this study to determine the effects of the play intervention on children who were receiving injections.  The focus was on healthy, normal preschoolers who were receiving immunization in the clinical setting.  Data collection occurred in three Pediatricians' offices over a three-month period.  The Palmar Sweat Print (PSP) developed by Silverman and Powell in 1944 was used to measure anxiety.  The PSP photometrically measures the sweat volume on the palmar surfaces of the fingers. There were 40 subjects in the experimental group and 32 in the control group.  Three Palmar Sweat Prints were obtained for each subjects:  1) one as a baseline reading; 2) one after an explanation concerning the purpose for, nature of, and location of injections for subjects in the control group, and after this same explanation and doll play with the injection equipment for subjects in the experimental group; and 3) one after the child had received his immunization by the investigator.  It was expected that the prints of for the control group would either remain the same, increase, or decrease slightly.  It was expected that the prints for the experimental group would significantly decrease on the second and third readings after they play therapy.  Sixteen subjects were excluded from study because they did not cooperate.  The Palmar Sweat readings were analyzed separately for this 16 uncooperative subjects.  A two-way analysis of variance revealed there was no difference between the two groups on the readings, and that there was no interaction between the two groups and the readings.  The one significant finding (F=10.9. p

description: We demonstrate how a multiplicative splitting method of order P can be used to construct an additive splitting method of order P + 3. The weight coefficients of the additive method depend only on P, which must be an odd number. Specifically we discuss a fourth-order additive method, which is yielded by the Lie-Trotter splitting. We provide error estimates, stability analysis, and numerical examples with the special discussion of the parallelization properties and applications to nonlinear optics.

description: Unemployment rates among persons with disabilities are high, with women being at greater risk due to the interaction of gender and disability. Although studies portray the inequality, oppression, and exclusion women with disabilities encounter, little research is available on the impact of unemployment on women with physical disabilities. This qualitative study explores the daily experiences of unemployed women with physical  disabilities in Tamale, Ghana. Phenomenology and focus group research approaches guided this study, since so  little is known about how unemployment impacts the lives of women with physical disabilities. Purposive and snowball sampling were used to recruit 10 women with  physical disabilities for in-depth interviews. Purposive sampling was also used to recruit 14 representatives from the government and civil society organizations for two multiorganizational focus groups

description: The present study was undertaken to determine relationships between pre- and postoperative arterial oxygen tension levels in selected patients undergoing openheart surgery with cardiopulmonary bypass.  A second purpose was to determine how the variables age, weight, and smoking were related to both pre- and postoperative arterial oxygen levels.  Fourteen subjects admitted to the McKay-Dee Hospital in Ogden, Utah for openheart surgery from November 1973 to April 197U comprised the study sample.  Subjects were weighed on admission to the hospital and categorized as normal or overweight.  Subjects were also categorized as either smokers or nonsmokers.  Arterial blood samples were drawn preoperatively and on the third postoperative day.  A third sample was drawn on available subjects the ninth postoperative day.  Data were analyzed using multiple correlation techniques.  Pre- and postoperative arterial oxygen tensions for each subject in the sample were variable.  Preoperatively, all but two subjects had arterial oxygen levels in the mild hypoxemic range.  All subjects were hypoxemic postoperatively with the lowest values occurring on the third postoperative day.  Analysis of data by the categories age and weight showed no statistically significant correlation between these variables and the pre- and postoperative arterial oxygen levels. An analysis of variance was conducted on all combinations of subject variables for both pre- and postoperative arterial oxygen values. No statistically significant results were found.  Smoking was a statistically significant variable related to the arterial oxygen tensions of subjects in this investigation.  There were no statistically significant differences shown between the smokers! and nonsmokers! preoperative arterial oxygen tensions.  On the third postoperative day, however, the arterial oxygen tensions of the smokers were significantly lower than the arterial oxygen tensions of nonsmokers.  Another statistically significant finding was that subjects with the highest preoperative arterial oxygen values had the lowest arterial oxygen values on the third postoperative day.
Quantifying component degradation and level of aging in power converters using spread spectrum time domain reflectometry
Creators: name: Nasrin, Most Sultana
Publisher: name: University of Utah
Year: 2013

description: Power converters are frequently exposed to electrical stresses such as over voltage, over current and switching impulses during their regular operations. These stresses may not result in immediate failure of a power converter. However, over longer periods they cause gradual degradation of critical components inside the converter, which ultimately leads to a complete failure of the converter. Failure of a power converter might disrupt the operation of the entire system, occasionally causing catastrophic outcomes. Estimating a converter's state of health and predicting the remaining life involves extensive research in semiconductor device physics and circuit theory, and is both important and challenging. There is always a dire need to determine the level of aging in power converters so that an approximate time to failure could be predicted. A reflectometry technique was applied to power converters to identify failure and aging associated to critical components inside a power converter. In addition, mechanisms for gradual shift in measurable electrical parameters of power converter components over long durations have been studied under the scope of the project. While there exist several other techniques for predicting reliability and aging of power converters, they are limited to characterizing isolated components only. Whereas using the proposed technique, estimating the component degradation in energized circuits is possible. Spread spectrum time domain reflectometry (SSTDR) has been commercially used for detecting aircraft wiring faults during the last decade, however, it was never applied to components in a power converter. During the preliminary stage of this project SSTDR was applied to a DC-DC converter circuit, and several key parameters such as MOSFETs ON resistance was extracted to characterize MOSFET aging. Later on, this technique was applied to different other components in an H-bridge AC-AC converter for failure rate estimation and reliability analysis. The MTTF (mean time to failure) was calculated based on the SSTDR generated data. The conducted research has initiated other SSTDR based prognostics and state of health measurement methods applicable to PV panels, electric machines and batteries.

description: Today, empathy is repeatedly considered a highly important influence in human interaction, yet our active and embodied practice of empathy seems scarce.    Empathy is commonly recognized by many academic fields including philosophy, psychology and biology. In my experience as a dancer, my movement education has had a profound influence on my understanding of others. Teaching and learning movement is an interchange that is inescapably an act of empathy. But what is empathy? What does it require of the body? What is our empathic capacity?   The main purpose of this thesis is to illuminate the relationship between movement and empathy. I will review many scientific models and draw parallels to my creative endeavors by analyzing and reflecting on two choreographic works Sync and Revealing Wavelengths. I use empathy in the creative process and as the subject and product of my art. How can choreography as a research tool add to the current empathic paradigms?  Conclusively, I determine that human movement and physical experience are fundamental to the empathic process. My choreographic explorations were effective in underlying complexity and intricate details of this concept of humanity, which will continue to educate me in life and in the field of dance.

High energy materials

description: High energy materials are commonly used as solid rocket motors propellants. The properties of HE materials can be determined experimentally; however, the hazards associated with experiments on these materials, as well as the costs, make this approach unattractive. The simulations of these materials require techniques that can bridge submicron scales and engineering scales. Micromechanics provides such  techniques. The objective of this research is to investigate the effects of stress bridging on predicting the effective properties of high energy materials group. The research focused on polymer bonded explosives (PBXs), since detailed numerical simulations of PBXs are computationally expensive. The generalized method of cells was explored for this research and its predictions of elastic moduli with and without stress bridging.  The results show that stress bridging affects the estimated properties considerably.  The generalized method of cells without stress bridging is shown to underestimate the elastic moduli of the polymer bonded explosives.  Micromechanics analysis requires that the fundamental material properties of the constituents are known initially. The composite material properties can be determined experimentally by testing actual composite specimens. However, in recent years, more and more attention has been given to the development of the analytical and numerical models for predicting composite material properties from the properties of  the constituent materials and their relationship to each other. The other part of this research is to identify the Representative Volume Element (RVE) and the boundary  conditions for calculation of transverse shear modulus (G23) and then compare the results to the other classical micromechanics solutions.  The results show that the proposed approach for identifying the Representative Volume Element (RVE) and the boundary conditions predict as accurately as the  other classical micromechanics solutions.

description: Within a limited time of excision and grafting autografts can be compromised or lost due to infection. An in vitro study was done to test susceptibility of four antibiotic solutions against the most common bacteria found in the University of Utah's Intermountain Burn Center. Cost analysis of each antibiotic solution was also addressed. Utilizing two rows of Whatman filter paper disks on four separate Mueller-Hinton agar plates, antibiotic solutions were applied in two volumes and placed in a 35°C incubator for 16 hours. Zones of inhibition were measured and 'susceptibility vs resistance' was determined. It was found that against Acinetobacter baumannii, Methicillin-resistant Staphylococcus aureus (MRSA), and Staphylococcus aureus, 25% Chlorhexidine Gluconate (Hibiclens) in sterile water, demonstrated superior susceptibility over 5% Mafenide Acetate (Sulfamylon), 1/4 strength Acetic Acid (AA) and TABI solutions (Bacitracin 10,000u/me, Neomycin 2%, Polymyxin 500,000u, 1/2cc Iodine in 1000ml saline). Pseudomonas aeruginosa was most susceptible to AA solution followed by Sulfamylon. Patient charges for 24-hours utilization of solution showed AA as the least expensive followed by Hibiclens, TABI and Sulfamylon.

description: Stimuli-responsive hydrogels are called "smart" materials because they autonomously respond to environmental stimuli. For example, pH-responsive hydrogels swell at lower pH levels and deswell as the pH increases. Hydrogel-based sensors could prove beneficial for providing continuous monitoring of bioreactors. The motivation of this project is to create a hydrogel-based sensor that can be used for bioreactor monitoring to help researchers monitor bioreactor conditions. The magnitude of the swelling/deswelling behavior can be measured by placing a sample of the hydrogel in a piezoresistive sensor. The degree of swelling/deswelling is directly proportional to the change in pH of the aqueous solution in which it is placed. In this project, an initial characterization of the hydrogel response was performed, followed by an analysis of the hydrogel components and optimization of the hydrogel response based on those components. The longevity of the hydrogel response was tested in terms of shelf life and response after multicycle testing. A hydrogel sample was then synthesized in situ in a microsensor and tested to determine the ability to transport hydrogels and how the miniaturization of the sensor may affect the stimuli response. In all experiments, the response time and magnitude results were compared to determine the effect of the noted changes on the kinetics of the swelling behavior of the material in order to find the optimal composition, thickness, and device specifications that will yield the desired response time and sensitivity.

description: The chemical composition of cosmic rays is critically important to understanding cosmic ray sources as well as a cosmic ray's propagation through the Galaxy and Universe. Theories explaining the features seen in the cosmic ray spectrum depend strongly on the chemical composition of cosmic rays. Composition has implications for anisotropy studies as atomic nuclei with large atomic number are more susceptible to deflection by Galactic and extragalactic magnetic fields. This work presents a composition analysis using data from the Telescope Array (TA) experiment and uses the point of shower maximum, Xmax, as the marker of a cosmic ray's chemical composition. TA is the largest cosmic ray detector in the Northern Hemisphere and makes use of both ground array as well as nitrogen fluorescence methods for detecting cosmic rays. This analysis combines both ground array and fluorescence data in a hybrid analysis to obtain resolutions of 0.5◦ in reconstructed pointing directions and 20 g/cm2 in reconstructed Xmax. Above 1018.5 eV, measured Xmax distributions using hybrid TA data are compatible with proton MC and exclude iron. However, above 1019.3 eV, the statistical power is limited and the data is compatible either proton or iron MCs. The shapes of the Xmax distributions independent of their means are compared, showing again that the data is compatible with protons and incompatible with iron. However, the statistical power for this measurement is limited above 1018.8 eV.

description: The main part of this dissertation starts with a generalization of the entangling power, which quantifies the ability of unitary operators to generate entangled states by their action on the computational basis. The entangling power has been defined for an evenly split bipartite system, whose states live in a Hilbert space of the form H1 X H2 where dimH1 = dimH2. I generalize this so that we can consider an odd number of qubits. Entangling power is defined in terms of the linear entropy, a linearization of the von Neumann entropy, whose polynomial form allows one to derive simpler expressions for functions of the entropy. The linear entropy measure is lifted from the state space to the operator space to measure the entanglement of  operators. In particular, we focus on the three qubit case, where dimH1 = 2 and dimH2 = 4, as a step to understanding entanglement in many qubit systems. This is the content of Chapter 3.

description: Blind and low vision (BLV) developers create websites to share knowledge and showcase their work. A well-designed website can engage audiences and deliver information effectively, yet it remains challenging for BLV developers to review their web designs. We conducted interviews with BLV developers (N=9) and analyzed 20 websites created by BLV developers. BLV developers created highly accessible websites but wanted to assess the usability of their websites for sighted users and follow the design standards of other websites. They also encountered challenges using screen readers to identify illegible text, misaligned elements, and inharmonious colors. We present DesignChecker, a browser extension that helps BLV developers improve their web designs. With DesignChecker, users can assess their current design by comparing it to visual design guidelines, a reference website of their choice, or a set of similar websites. DesignChecker also identifies the specific HTML elements that violate design guidelines and suggests CSS changes for improvements. Our user study participants (N=8) recognized more visual design errors than using their typical workflow and expressed enthusiasm about using DesignChecker in the future.

description: Fibrinolysis, the proteolytic degradation of the fibrin fibers th a t stabilize blood clots, is initiated when tissue-type plasminogen activator (tPA) activates plasminogen to plasmin, the main fibrinolytic enzyme. Many experiments have shown that coarse clots made of thick fibers lyse more quickly than fine clots made of thin fibers, despite the fact that individual thick fibers lyse more slowly than individual thin fibers. Other experiments show the opposite result. Reaction-diffusion models have been the standard tool for investigating fibrinolysis, and have been successful in capturing the wave-like behavior of lysis seen in experiments. These previous models treat the distribution of fibrin within a clot as homogeneous, and therefore cannot be used directly to study lysis of fine and coarse clots. We create a model that includes a spatially heterogeneous fibrin concentration, as well as a more accurate description of the role of fibrin as a cofactor in the activation of plasmin. Our model predicts spatiotemporal protein distributions in reasonable quantitative agreement with experimental data. The model also predicts observed behavior such as a front of lysis moving through the clot with an accumulation of lytic proteins at the front. In spite of the model improvements, however, we find that one-dimensional (1-D) continuum models are unable to accurately describe the observed differences in lysis behavior between fine and coarse clots. Hence, we develop a three-dimensional (3-D) stochastic multiscale model of fibrinolysis. A microscale model representing a fiber cross section and containing detailed biochemical reactions provides information about single fiber lysis times and the length of time tPA stays bound to a given fiber cross section. Data from the microscale model is used in a macroscale model of the full fibrin clot, from which we obtain lysis front velocities and tPA distributions. We find that the number of fibers in a clot impacts lysis rate, but so does the number of tPA molecules relative to the surface area of the clot exposed to those molecules. Depending on the values of these two quantities (tPA number and surface area), for given kinetic parameters, the model predicts coarse clots lyse faster or slower than fine clots, thus providing a possible explanation for the divergent experimental observations. We also use the model to predict values of unmeasured reaction rates and to suggest desirable characteristics of fibinolytic drugs. We find that a tPA variant that binds less strongly to fibrin causes faster degradation rates than normal tPA. We conclude by studying the effect of the inhibitors a 2-antiplasmin ( a 2-AP), plasminogen activator inhibitor-1 (PAI-1), and thrombin activatable fibrinolysis inhibitor (TAFI) on lysis. We find that a 2-AP is the stongest inhibitor, but lysis is most delayed when a 2-AP and TAFI work together.

drug use

description: The current study investigated the relationship between individual adolescent drug use, friends' drug use, and school, family, and community prosocial environments. Survey data from the 2007 SHARP survey collected from schools in a western state were analyzed to better understand the relationship between the  aforementioned variables. A total of 10,767 eighth grade student surveys were used in the analysis. Single-level logistic regression analyses were then conducted with the dataset and results indicated a significant positive relationship between peer substance use and adolescents' own individual substance use, which is consistent with prior substance abuse research. Analyses also indicated that school, family, and community prosocial environment did act as protective factors by reducing the likelihood of adolescent drug use; however, these factors did not significantly moderate the relationship between friends' drug use and eighth grade adolescent drug use, although community and family prosocial environment interaction variables did approach statistical significance. Results from the present study indicate that drug use by adolescents' friends is a significant risk factor that appears to contribute to eighth grade adolescent substance use at a level that may not be easily reduced. Future research on prosocial environments that includes a more diverse sample, a variety of age groups, and multiple measures may provide a better understanding of these protective factors.

description: We survey free magmas and we explore the structure of their submagmas. By equipping the cyclic free magma with a second distributive operation we obtain a ringoid-like structure with some primitive arithmetical properties. A submagma is $k$-maximal when there are only $k-1$ submagmas between it and the free magma itself. These two tools, arithmetic and maximality, allow us to study the lattice of the submagmas of a free magma.

description: This dissertation attempts to detail the necessary and sufficient conditions for tropical cyclogenesis; specifically those environmental, convective, and thermodynamic properties that may determine the fate of disturbances with apparent genesis potential. Unlike previous observational case studies which evaluate a few cases with limited spatial and temporal resolution in-situ and satellite data, this study examines 1 2 developing and four nondeveloping cases from recent (since 2005) tropical cyclone field campaigns using dropsonde data from multiple agency aircraft, as well as data from infrared and multiple passive microwave satellite platforms. Results, composited for all developing cases, indicate that the inner core of developing disturbances prior to genesis exhibits a midlevel moisture that is greater than the surrounding environment, high relative humidity, a warm temperature anomaly at upper levels that progressively lowers through genesis, and a cool, dry anomaly at low levels. Likewise, the vertical alignment of the low- and midlevel vorticity centers is necessary for formation. The midlevel moisture content only shows a slight "progressive moistening" during the pregenesis stage, while the total precipitable water does not apparently increase among the cases studied. Consistent with conclusions from previous observational and modeling studies, the cool, dry anomaly and increased static stability at low levels in the composite, perhaps as a result of persistent convective precipitation near the center within 1-3 days of genesis, appears to be a necessary condition for formation; this genesis pathway suggests that an initially stronger midlevel vortex precedes primarily low-level spin-up within a day of formation. Among the convective properties examined using the satellite datasets (raining area, convective intensity, area of intense convection, duration, and proximity), the results suggest that the proximity and duration of precipitation within three degrees of the center are the most important properties for formation. However, the developing cases studied do not exhibit any common distinguishing convective characteristics during the pregenesis stage; not all developing cases exhibit widespread, intense convective episodes, and although some of the cases exhibit their most "favorable" convective episodes (in terms of intensity, area, and proximity to the center) around 30-36 hours prior to formation, in a few cases that episode occurs as many as 3 days before formation.

Note. Vulcano et al. (1976: 518) state that in the original description of Dichotomius lycas Guyana is mentioned as the collecting locality, while the label bears the location Bahia. This is incorrect, as the original description in Felsche (1901: 144) clearly mentions Brazil, not Guyana. The record in Blackwelder (1944: 207) is likely taken from Gillet (1911b: 61), which mentions “ Guyana ” without clarification as to which of the Guianas. Given the absence of any recent records, we consider the occurrence of this species in the research area doubtful and in need of confirmation.

description: A magma is called equidecomposable when the operation is injective, or, in other words, if $x+y=x'+y'$ implies that $x=x'$ and $y=y'$. A magma is free iff it is equidecomposable and graded, hence the notion of equidecomposability is very related to the notion of freeness although it is not sufficient. We study main properties of such magmas. In particular, an alternative characterization of freeness, which uses a weaker condition, is proved. We show how equidecomposable magmas can be split into two disjoint submagmas, one of which is free. Certain tranformations on finite presentations permit to obtain a reduced form which allows us identify all the finite presented equidecomposable magmas up to isomorphisms.

Characterizing the Function of MON1A in Membrane Traffic and Organelle Maintenance in the Secretory Pathway
Creators: name: Bagley, Dustin C.
Publisher: name: University of Utah
Year: 2014

description: Mon1 is an evolutionarily conserved gene that has homologs from yeast to humans. The original identification and characterization of Mon1 in mammals, Mon1a, was performed in a study that identified Mon1a as a modifier of iron homeostasis in mice. That work demonstrated that C57BL mice harbor an intrinsic "gain-of-function" mutation that resulted in an excess of the iron exporter ferroportin at the cell surface of iron recycling macrophages. The study also showed that Mon1a had a function in the movement of soluble and membrane-bound proteins through the secretory apparatus. We were able to expand on those findings using protein interaction and RNAi analysis to demonstrate that Mon1a associates with the molecular motor Dynein, known to function in ER-Golgi trafficking. Subcellular localization demonstrated that Mon1a peripherally associates with the ER membrane. Further, RNAi-mediated reduction of Mon1a resulted in a significant decrease in the formation of ER-derived vesicle, which resulted in impaired trafficking in the early secretory pathway. We also determined that the movement of the viral protein VSVGtsGFP from the Golgi to the plasma membrane was delayed in Mon1a-depleted cells. A yeast two-hybrid (Y2H) analysis of Mon1a interacting partners found that a F-BAR domain-contain protein, FCHo2, known to affect membrane traffic at the cell surface, physically associated with Mon1a. RNAi-mediate reduction of Mon1a or iv FCHo2 resulted in severe Golgi fragmentation, which was dependent on the activity of the Golgi GTPase Rab6. The RNAi-mediate phenotypes of Mon1a and FCHo2 were not identical as only FCHo2 silencing-induced Golgi fragmentation was cell cycle-dependent. We show using FRAP analysis that FCHo2 is necessary for the lateral movement of membrane proteins between Golgi elements that link Golgi cisternae. We determined that FCHo2-mediated Golgi fragmentation resulted in immature glycosylation moieties at the plasma membrane. This dissertation describes novel roles for both Mon1a and FCHo2 in membrane traffic in the secretory pathway and Golgi architecture maintenance.
