Jesse W. Smith letter to Scott C. Bone, August 6, 1920
No full textIn this letter dated August 6, 1920, Jesse "Jess" W. Smith, secretary at Harding Headquarters, writes to Scott C. Bone of the National Republican Committee. The Cleveland News-Leader and other city newspapers are publishing a series of articles contributed by "The Girl Next Door to Hardings." The author is Eleanor Margaret Freeland, a teacher and close friend of the Hardings who lives next door to their home in Marion, Ohio. Her articles provide an intimate, wholesome portrait of Warren and Florence Harding. Smith suggests that the Republican National Committee circulate these for a wider audience, and asks that Freeland be compensated accordingly.
This letter is part of the Warren G. Harding Papers (MSS 345). This collection includes correspondence, business records, and other materials documenting Harding’s business career as owner and editor-in-chief of The Daily Marion Star, as well as the various stages of his political career. A significant portion of the collection, and what’s available on Ohio Memory, highlights his 1920 presidential campaign, spanning just before publicly announcing his candidacy to handily defeating Ohio Governor James M. Cox in the election. Correspondents include both Ohio and national businessmen, political figures, and ordinary citizens writing with questions, support, congratulatory notes, and campaign advice. Some of the most interesting insights into the tumultuous political climate in the U.S., the extreme factionalism within the Republican Party in Ohio, and Harding’s campaign strategies are described in letters between Harding and his campaign manager, Harry M. Daugherty. Some of the topics addressed include women’s suffrage, Prohibition, the League of Nations, African American representation and issues, and lingering peace negotiations following World War I
Toric mirror symmetry and GIT windows
No full text"This thesis, partially based on the author's joint work [HZ20], studies mirror symmetry for toric varieties from the perspective of geometric invariant theory. We translate GIT constructions of toric varieties into skeletal terms and study them in the context of wrapped Fukaya categories and wrapped constructible sheaves. We explain how the mirror image of the Halpern-Leistner-Sam ""magic window"" for quasi-symmetric torus actions computes the category associated to the equivariant semistable skeleton upon stop removal, where the generating cotangent fibers are described by a generic shift of a lattice zonotope in the real character space of the torus. After identifying the ""FI parameter space"" of the B-model GLSM with the GKZ complex parameter space of the skeletal LG A-model, homological mirror symmetry in the quasi-symmetric case becomes two geometric incarnations of the Špenko-Van den Bergh schober over C^k stratified by a complexified periodic hyperplane arrangement whose complement models both parameter spaces. We obtain a universal deformation of skeletons interpolating variation of parameters."Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2023-08-01The student, Jesse Huang, accepted the attached license on 2021-06-06 at 18:34.The student, Jesse Huang, submitted this Dissertation for approval on 2021-06-07 at 11:46.This Dissertation was approved for publication on 2021-06-15 at 10:46.DSpace SAF Submission Ingestion Package generated from Vireo submission #16639 on 2022-01-12 at 12:51:22Made available in DSpace on 2022-01-12T22:34:38Z (GMT).

Suitability of soxhlet extraction to quantify microalgal fatty acids as determined by comparison with in situ transesterification
No full textAuthor Posting. © The Author(s), 2011. This is the author's version of the work. It is posted here by permission of Springer for personal use, not for redistribution. The definitive version was published in Lipids 47 (2012): 195-207, doi:10.1007/s11745-011-3624-3.To assess Soxhlet extraction as a method for quantifying fatty acids (FA) of microalgae, crude lipid, FA content from Soxhlet extracts and FA content from in-situ transesterification (ISTE) were compared. In most cases, gravimetric lipid content was considerably greater (up to 7-fold) than the FA content of the crude lipid extract. FA content from Soxhlet lipid extraction and ISTE were similar in 12/18 samples, whereas in 6/18 samples, total FA content from Soxhlet extraction was less than the ISTE procedure. Re-extraction of residual biomass from Soxhlet extraction with ISTE liberated a quantity of FA equivalent to this discrepancy. Employing acid hydrolysis before Soxhlet extraction yielded FA content roughly equivalent to ISTE, indicating that acidic conditions of ISTE are responsible for this observed greater recovery of FA. While crude lipid derived from Soxhlet extraction was not a useful proxy for FA content for the species tested, it is effective in most strains at extracting total saponifiable lipid. Lipid class analysis showed the source of FA was primarily polar lipids in most samples (12/18 lipid extracts contained 15%). This investigation confirms the usefulness of ISTE, reveals limitations of gravimetric methods for projecting biodiesel potential of microalgae, and reinforces the need for intelligent screening using both FA and lipid class analysis.2012-11-0
Free Zone Incentives in MERCOSUR Countries and WTO Law
No full textPublished source: Gabriel Gari, 'Free Zone Incentives in MERCOSUR Countries and WTO Law' (2011) 6 Global Trade and Customs Journal, Issue 5, pp. 223–244
ID: GTCJ2011031This article examines the consistency of the incentives offered by free zone regimes in Argentina, Brazil, Paraguay, and Uruguay with World Trade Organization (WTO) law. It suggests that some of the incentives offered to free zone users are inconsistent with the Agreement on Subsidies and Countervailing Measures (ASCM) because they constitute a ‘subsidy’ within the meaning of the ASCM, subject de iure or de facto to export performance, most notably, exemptions of direct taxes, exemptions of custom duties on the import of capital goods, exemptions of payment of social welfare charges, unqualified exemptions on payment of indirect taxes, and the possibility to supply goods or services to free zone users at promotional rates. By contrast, this article suggests that there are no significant inconsistencies between free zone incentives and the General Agreement on Trade in Services (GATS) but warns that the situation could change in the future if, as a result of multilateral negotiations, MERCOSUR countries opt for extending their GATS commitments to new sectors and modes of supply
Microbial Regulation of Soil Greenhouse Gas Emissions in a Non-Bloat Legume Grazing System
No full textCattle pastures are a source of greenhouse gas (GHG) emissions, including enteric methane from ruminating cattle, carbon dioxide (CO2), and nitrous oxide (N2O) from microbial respiration of soil carbon (C) and nitrogen (N). Producers may introduce non-bloat legumes to cattle pastures to improve soil N content, increase cattle protein uptake, and decrease enteric methane emissions. However, such land management changes can alter soil microbial communities, potentially increasing net system GHGs. The research goal was to determine whether non-bloat legumes alter soil microbial community structure, activity, and N2O emissions. Grazed pastures with introduced Veldt cicer milkvetch and common sainfoin were surveyed for differences in GHGs, microbial community structure, and extracellular enzyme activity for two growing seasons. Seasonal shifts explained most microbial community changes; however, communities structured according to legume treatment and legume microbial community structure correlated with increasing soil nitrate (NO3-) content, particularly in cicer milkvetch plots. Soil N2O fluxes did not differ on sampling dates, however cicer milkvetch tended towards larger N2O emissions. Pasture soil microbial community changes did not translate to increased N2O emissions on sampling dates. Additional protein found in non-bloat legumes may increase urine urea-N content in cattle affecting soil processes. Urine containing low or high concentrations of 15N and 13C labeled urea was added to soil microcosms under controlled conditions to better understand the impact of urine on soil N2O emissions, microbial N cycling communities, and N2O sources. Ammonia oxidizing bacteria (AOB) were the most active nitrifiers following urine addition. Denitrifiers contributed the most N2O in urine amended soils and their dynamics varied. After urine deposition, nirS gene abundance and transcript increases were greater and more sustained than nirK, while nirK increased activity more rapidly but did not increase gene abundance. Urine toxicity and increased clade II nosZ transcription likely reduced initial N2O emissions at high urea concentrations, resulting in no difference between cumulative soil N2O fluxes between urea rates and a lower urine-N emission factor for high urea soils. These findings support the use of non-bloat legumes in pastures, particularly when considering the potential reduction in enteric methane emissions, reducing net pasture system GHG emissions
Relationship between lightning flash rates and radar observations from Colorado and Australia
No full textSummer 1999.Also issued as Jesse James Ryan's thesis (M.S.) -- Colorado State University, 1999.Relationships between lightning flash rates and radar observations were examined for two regions; northeastern Colorado and Darwin, Australia. Five case studies from Colorado were analyzed using observational data from: the CSU-CHILL multiparameter radar, the ONERA VHF lightning interferometer, a field change meter and the National Lightning Detection Network. Three case studies from tropical Australia were analyzed using data from: the C-POL BMRC/NCAR multiparameter radar, a field change meter and an Advanced Lightning Detection Finder network. For each case, parameters such as peak echo height (H), storm area (A), and storm volume (V) were computed using different radar reflectivity and temperature thresholds. Storm areas and volumes were computed above the altitude of various temperature thresholds. Cloud echo-top height (Ho) was defined as the peak height using the O dBZ reflectivity threshold. Correlations existed between H, A, and V, and the total lightning flash rate on a majority of the cases and were strongest when higher reflectivity and colder temperature thresholds were used. An increased correlation between H, A, and V, and total flash rate for high reflectivity (> 20 dBZ) thresholds was noted for storms which contained broad areas of stratiform precipitation. Since stronger correlations were found between total flash rate and the product of A and V (AV) than between the total flash rate and H5, this study suggests that significant error can be introduced by assuming that the horizontal scale of a thunderstorm charge generation is comparable to the vertical scale. In addition, we show that AV and H5 at high reflectivities (> 20 dBZ) are both better correlated to total flash rate than H/, a parameter commonly used as a predictor for lightning flash rates in modeling studies. The ratio of intracloud (IC) to cloud-to-ground (CG) lightning was also analyzed for each case. This ratio was subsequently compared to cold cloud thickness (CCTh), defined as the distance between cloud top and the environmental freezing level. The relationships between IC/CG ratio and CCTh were similar to prior research, except for storms with high (> 40) IC/CG ratios.Sponsored by the National Oceanic and Atmospheric Administration under grant NA76GP0370

Recycling citizenship: infrastructural transformation and access struggles in Dakar's solid waste management system
No full textIn transforming the city's waste infrastructure towards mechanized incineration, a pending waste management reform in Dakar stands to dispossess over a thousand recycling workers, whose future access to waste and participation in the city's waste system is in limbo. In the face of an infrastructural reform that compromises their livelihoods, the workers draw on their ties to global civil society actors and a transnational advocacy network as they mobilize to defend their access to waste. This study analyzes the workers’ mobilization as a citizenship struggle, given that their claims signify efforts to influence the political economy that shapes their livelihoods. Situated at the intersection of infrastructural violence, transnational activism, and substantive citizenship scholarship, this research draws on qualitative field research and document analysis to show how ties to global civil society actors can erode the practice of citizenship by weakening the capacity of the workers to be politically engaged and to shape the fate of their polity. In this case, the international civil society groups and transnational advocacy networks involved are financially supportive but politically uninvolved in ways that distance the workers from the state and disenable them from influencing government decision making. The emphasis in transnational activism literature on the emancipatory implications of local-global alliances for local struggles thus needs to be further scrutinized with respect to the ways in which these alliances transform local practices and formulations of citizenship.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-05-01The student, Rea Zaimi, accepted the attached license on 2015-11-19 at 14:54.The student, Rea Zaimi, submitted this Thesis for approval on 2015-11-19 at 15:01.This Thesis was approved for publication on 2015-12-01 at 16:49.DSpace SAF Submission Ingestion Package generated from Vireo submission #8809 on 2016-07-07 at 13:48:01Made available in DSpace on 2016-07-07T20:26:35Z (GMT).

Experimental Investigation of a Laminar Separation Bubble Subjected to Wing Structural Motion
No full textUnmanned aerial vehicles have proliferated in the last few decades, with applications that include military, commercial and recreational. Their size and typical flight velocities are characterized by moderate Reynolds numbers O(10^4-10^5). For such conditions, boundary layers can remain laminar and therefore are highly susceptible to separation and the generation of laminar separation bubbles (LSBs), when compared to more conventional aircraft. Extensive research has been done to study the influence of Reynolds number, angle of attack, sweep angle or freestream turbulence level on the nature of LSBs. However, the study of LSBs subject to unsteadiness is rather limited. This is especially relevant for small aircraft that typically fly in gusty environments such as cities. The problem is aggravated by the recent shift toward composite manufacturing, which allows more efficient high-aspect-ratio configurations, but that deform considerably more when subjected to unsteady loads.The LSB that forms on the suction side of a modified NACA 64_3-618 airfoil at a chord-based Reynolds number of Re = 200k is studied in a series of wind tunnel experiments conducted at The University of Arizona. Three different flow measurement techniques are considered in the experiments to identify the bubble: surface pressure measurements, Particle Image Velocimetry and Infrared Thermography. The capabilities of the three techniques are first explored in a static characterization of the LSB over a range of angles of attack. For the conditions tested, excellent agreement between the techniques is obtained, showing an upstream shift of the bubble with increasing incidence. For the study of static LSBs, the infrared approach is superior, given its higher spatial resolution and experimental simplicity.The complexity is then increased to study the influence of aerodynamic unsteadiness on the bubble. For this purpose, two different types of structural motion are imposed on the wind tunnel model. A first experiment considers a pitching-type motion, with reduced frequencies up to k = 0.25. While surface pressure measurements and PIV are not heavily affected by the change in experimental conditions, the infrared approach becomes limited by the thermal response of the surface. To overcome this limitation, an extension of the recently proposed Differential Infrared Thermography (DIT) method is considered. Even so, the unsteady behaviour of the bubble can be only partially detected with this method. All-three techniques considered indicate a hysteresis in bubble location between the pitch up and pitch down parts of the motion, caused by the effect of the aerodynamic unsteadiness on the adverse pressure gradient.The second type of structural motion studied consists of a sinusoidal plunge, with an amplitude of h = 6% of the airfoil chord and a reduced frequency of k = 0.67. The surface pressure measurements and PIV still capture a hysteresis in bubble location along the cycle, expressed in terms of the effective angle of attack induced by the plunging motion. However, due to the increased frequency of the motion, the thermal response of the surface reduces and the infrared approach fails to detect the unsteady bubble. Aerospace Engineerin
