Space market model space industry input-output model

The goal of the Space Market Model (SMM) is to develop an information resource for the space industry. The SMM is intended to contain information appropriate for decision making in the space industry. The objectives of the SMM are to: (1) assemble information related to the development of the space business; (2) construct an adequate description of the emerging space market; (3) disseminate the information on the space market to forecasts and planners in government agencies and private corporations; and (4) provide timely analyses and forecasts of critical elements of the space market. An Input-Output model of market activity is proposed which are capable of transforming raw data into useful information for decision makers and policy makers dealing with the space sector

The Female Flute: Kṛṣṇa's Muralī in the Poetry of Sūrdās

A central figure in the rise of religious literature in the vernacular languages of north India in the early modern era was the poet-saint Sūrdās, whose poetry played a defining role in the spread of popular devotion, bhakti, to Kṛṣṇa, one of Hinduism s most well known deities. A salient feature in several of the poems ascribed to Sūrdās that depicts the iconic flute-playing Kṛṣṇa is that the flute itself appears as a female persona – Muralī. This thesis is the first study to ask why the flute appears as a woman and how the motif evolves throughout these poems. These questions are important because they engage with an understudied aspect of a central Hindu deity in of its most popular and defining representations, and because they offer a sharpened focus on the concepts of gender and devotion that deity might be perceived to embody. Utilising a theoretical outlook informed by performativity, intertextuality and gender studies, the study maps the various appearances of the female flute in both the early and late layers of the literary tradition connected with Sūrdās. It concludes that Muralī, the female flute, both functions as a religious symbol that encapsulates a general tension in the image of the flute-playing Kṛṣṇa between dichotomies such as nature and culture, gendered and ungendered, and as a rhetorical figure through which the poetry of Sūrdās can discuss competing positions on the dynamic between gender norms and religious imperatives

The Influence Of Soil Organic Matter (SOM) In Soils From Long-Term Experiments: Measurements Of Compression Properties, Water Release Curves, Thermogravimetry, Acoustical Impedance And Neutron Tomography

Soil Organic matter (SOM) is a very important factor in soil productivity and health. As SOM is the basis of nutrient cycling in soil, it has important consequences for both plant growth and the development of the root system. Also, organic matter influences the physical and mechanical properties of soils by improving soil structure and changing the soil pore system. Soil physical properties determine soil health and regulate plant growth by controlling root development and maintaining the availability of water and nutrients to plants. The effect of soil organic carbon (SOC) on the consolidation behaviour of soil from two long-term field experiments at Rothamsted (the Broadbalk winter wheat experiment and Hoosfield spring barley) has been investigated. These experiments are located on soil with similar particle size distributions, but with SOC contents ranging from approximately 1 to 3.5 g/100g. Soils taken from plots with contrasting SOC contents were compressed and deformed in a triaxial cell and the normal consolidation and critical state lines were determined. It has been found that the compression index was independent of SOC, but the void ratio at any given effective stress was highly correlated with organic carbon content. By comparison with uniaxial compression data, the apparent influence of SOC on the compression index is likely to be due to its effect on soil hydraulic properties rather than any intrinsic effects on strength. The plastic limit test appears to be a useful, simple and direct way of comparing soil physical behaviour and expected soil density. Thermogravimetric analysis (TG) has been used to deduce the organic matter content and its composition. Water release characteristics, and soil strength have been measured with the suction plate method and indirect tension method, respectively. As well the traditional measurements, the application of two relatively novel methods including neutron scattering by thin soil slices and non-invasive acoustical reflection from samples in an impedance tube is reported. The neutron scattering data has not proved useful as a result of the difficulties in obtaining and using soil samples in the required form. However, impedance tube measurements show that (a) the sound absorption of the surfaces of sand and soil samples decreases with increasing water content and (b) changes in absorption coefficient spectra deduced from impedance tube measurements on soil samples extracted from the long-term agriculture experiments, involving different organic matter content but similar water content, are consistent with the predicted effects of changes in porosity and permeability in rigid-porous air-filled media. The increase in bulk porosity with organic matter increase suggested by the acoustic measurements agrees with the results of the water retention and compression test

Transcriptomes of <i>Trypanosoma brucei</i> rhodesiense from sleeping sickness patients, rodents and culture:Effects of strain, growth conditions and RNA preparation methods

All of our current knowledge of African trypanosome metabolism is based on results from trypanosomes grown in culture or in rodents. Drugs against sleeping sickness must however treat trypanosomes in humans. We here compare the transcriptomes of Trypanosoma brucei rhodesiense from the blood and cerebrospinal fluid of human patients with those of trypanosomes from culture and rodents. The data were aligned and analysed using new user-friendly applications designed for Kinetoplastid RNA-Seq data. The transcriptomes of trypanosomes from human blood and cerebrospinal fluid did not predict major metabolic differences that might affect drug susceptibility. Usefully, there were relatively few differences between the transcriptomes of trypanosomes from patients and those of similar trypanosomes grown in rats. Transcriptomes of monomorphic laboratory-adapted parasites grown in in vitro culture closely resembled those of the human parasites, but some differences were seen. In poly(A)-selected mRNA transcriptomes, mRNAs encoding some protein kinases and RNA-binding proteins were under-represented relative to mRNA that had not been poly(A) selected; further investigation revealed that the selection tends to result in loss of longer mRNAs

Regularity results for some models in geophysical fluid dynamics

Tesis Doctoral inédita leída en la Universidad Autónoma de Madrid, Facultad de Ciencias, Departamento de Matemáticas. Fecha de lectura: 12-04-2019This thesis centers on the study of two di erent problems of partial di erential equations arising from geophysics and uid mechanics: the surface quasi-geostrophic equation and the so called, Incompressible Slice Model. The surface quasi-geostrophic equation is a two dimensional nonlo- cal partial di erential equation of geophysical importance, describing the evolution of a surface buoyancy in a rapidly rotating, strati ed potential vorticity uid. In the rst part of the talk, we will present some global regularity results for its dissipative analogue in the critical regime for the two dimensional sphere. After that, we will introduce the Incompressible Slice Model deal- ing with oceanic and atmospheric uid motions taking place in a ver- tical slice domain R2, with smooth boundary. The ISM can be understood as a toy model for the full 3D Euler-Boussinesq equa- tions. We will study the solution properties of the Incompressible Slice Model: characterizing a class of equilibrium solutions, establishing the local existence of solutions and providing a blow-up criterion.This thesis has been funded by a Severo Ochoa FPI scholarship for Centres of Excellence in R&D (SEV-2015-0554) and by the grant MTM2017-83496-P from the Spanish Ministry of Economy and Competitiveness

Southerners on New Ground: The Battle for Civil War Memory Since 1993

Between the years 2015 and 2020, over 300 Confederate symbols, including over 140 monuments, were removed from public land across the United States. This unprecedented movement to discard Confederate symbols reflected a shift in how Americans chose to remember the Civil War. By 2015, the wide-spread attack on the legacy of the Confederacy was much-anticipated. In fact, its foundation was laid during the Civil Rights Movement of the 1960s. This thesis fills a gap within the historiography of Civil War memory by exploring controversial events that reflect Americans’ contrasting interpretation of the American Civil War from the years 1993 to 2021. It argues that the attack on Confederate symbols is truly an attack on white supremacy. Further, the battle against Confederate symbolism is a continuation of the struggle for civil rights. The National Association for the Advancement of Colored People (NAACP) attacked the legacy of the Confederacy to start a national discourse concerning America’s racist past and to eradicate white supremacy. In doing so, it became an active agent for change in minimizing public displays of the Confederate flag. The children and grandchildren of the civil rights era continued the legacy of their forbearers, demonstrating that, despite the optimistic belief that the war against white supremacy was won after the Voting Rights Act had been passed, the war was just heating up. The war against Confederate symbols fit neatly within the folds of America’s two-party system. This thesis argues that the memory of the Civil War, starting in the early 1990s, became a highly contested political battlefield. Republicans used it as a mechanism to stir up votes by making it appear as if their opponents were erasing white culture. Democrats supported the removal of Confederate emblems in order to placate their constituents as they argued it was the best way to recognize America’s darker past without celebrating it. While politicians debated the issue, grassroots activism yielded the most tangible results. The NAACP, and more recently, the Black Lives Matter movement, attacked Confederate symbolism to shift the national debate to focus on contemporary issues posed by white supremacy and systemic racism
