O estudo tem por objetivo geral discutir a abordagem idiomática empregada pelo compositor na escrita das partituras do contrabaixo na grade orquestral, para, a partir daí, propor a tese de que tais excertos possam ter relevância considerável para o estudo técnico-musical do instrumentista, no que se defende a pertinência de sua adoção por intérpretes, professores e estudantes de contrabaixo. A metodologia de pesquisa inclui extensa revisão de literatura, com visita a autores do século 18 aos dias atuais, seguida de identificação de equivalências idiomáticas no repertório orquestral tradicional, contextualização das influências na escrita para o contrabaixo de Villa-Lobos e concluindo, por fim, com a proposição de uma seleção de excertos para a prática pedagógica. A tese é desenvolvida em três capítulos centrais. O primeiro trata da revisão de literatura sobre estudos de excertos orquestrais para contrabaixo e traça um panorama atual de sua aplicação em instituições locais, pondo em discussão, particularmente, a escassez desses materiais no âmbito da produção orquestral brasileira. O segundo capítulo aborda as influências na escritura das linhas de contrabaixo de Villa-Lobos, com descrição de aspectos idiomáticos na escrita do compositor para o contrabaixo em obras orquestrais, ilustrados com exemplos musicais de sua ...

The main goal is to discuss the idiomatic approach to the double bass on Villa-Lobos' orchestral works as a way to present the thesis that the excerpts of such orchestral works are relevant to the technique musical study of the performer, as well as localizing and indicating its pertinence to double bass performers, professors and students. The methodology chosen was the review of the literature followed by an identification of idiomatic equivalences from the traditional orchestral repertoire, the contextualization of Villa-Lobos' influences on its double bass writing and the selection of excerpts. The thesis is organized in three chapters, besides the introduction, conclusion and appendixes. The first chapter presents the review of the literature on orchestral excerpts for the double bass where today state of the art in Brazilians institutions is presented. The discussion is centered in the lack of material addressed to the studies of Brasilian orchestral works. The second chapter addresses the influences Villa-Lobos received while writing his double bass parts. Here idiomatic aspects of the composers writing for the instrument are described as well as a selection of works that better illustrate such writing and his symphonies, the Choros 10 and the Bachianas 9 are emphasized. The third chapter presents a excerpts selection for the double bass extracted from the works mentioned on chapter two, with emphasis on passages relevant for the technical study of the performer organized by type of idiomatism. The criteria for the selection of excerpts are also presented. At the end of this work it is possible to state that the composer had an elaborated and idiomatic writing for the double bass treating it with respect for its low range nature, ... / Doutor

abstract: In the last few years, significant advances in nanofabrication have allowed tailoring of structures and materials at a molecular level enabling nanofabrication with precise control of dimensions and organization at molecular length scales, a development leading to significant advances in nanoscale systems. Although, the direction of progress seems to follow the path of microelectronics, the fundamental physics in a nanoscale system changes more rapidly compared to microelectronics, as the size scale is decreased. The changes in length, area, and volume ratios due to reduction in size alter the relative influence of various physical effects determining the overall operation of a system in unexpected ways. One such category of nanofluidic structures demonstrating unique ionic and molecular transport characteristics are nanopores. Nanopores derive their unique transport characteristics from the electrostatic interaction of nanopore surface charge with aqueous ionic solutions. In this doctoral research cylindrical nanopores, in single and array configuration, were fabricated in silicon-on-insulator (SOI) using a combination of electron beam lithography (EBL) and reactive ion etching (RIE). The fabrication method presented is compatible with standard semiconductor foundries and allows fabrication of nanopores with desired geometries and precise dimensional control, providing near ideal and isolated physical modeling systems to study ion transport at the nanometer level. Ion transport through nanopores was characterized by measuring ionic conductances of arrays of nanopores of various diameters for a wide range of concentration of aqueous hydrochloric acid (HCl) ionic solutions. Measured ionic conductances demonstrated two distinct regimes based on surface charge interactions at low ionic concentrations and nanopore geometry at high ionic concentrations. Field effect modulation of ion transport through nanopore arrays, in a fashion similar to semiconductor transistors, was also studied. Using ionic conductance measurements, it was shown that the concentration of ions in the nanopore volume was significantly changed when a gate voltage on nanopore arrays was applied, hence controlling their transport. Based on the ion transport results, single nanopores were used to demonstrate their application as nanoscale particle counters by using polystyrene nanobeads, monodispersed in aqueous HCl solutions of different molarities. Effects of field effect modulation on particle transition events were also demonstrated. / Dissertation/Thesis / Ph.D. Electrical Engineering 2011

This dissertation examines the imaginative ways in which three postcolonial writers overcome a fractured collective past by creating a double-voiced discourse narrative framework that allows them to envision a reality that might-have-been while acknowledging the presence of dominant discourses that are. Morrison, Condé, and Farah overlap contradictory forms in order to show that narrative boundaries are self-imposed, mythical, and arbitrary. Intersection among these differing narratives in each text creates dialogism--a balance between dominant and counter-discourse. Because the contrasting viewpoints of dominant and counter-discourse both have a historical perspective, Morrison, Condé, and Farah work to retain a delicate intertextual fabric in their novels--a fabric woven from several narratives to create a text that rests paradoxically on the task of revealing the narrative contradictions while also showing that they can't be completely separated from each other as the singular hegemonic voice argues.

A systematic study of the change in proton single-particle occupancies in two neutrinoless double beta decay candidates, 130Te to 130Xe and 136Xe to 136Ba, has been performed. Final states in 129Sb, 129I, 135I and 135Cs have been populated using the (d,3He) single proton removal reaction. The deuterons were accelerated to 101 MeV using the coupled azimuthally varying field and Ring cyclotrons at the Research Center for Nuclear Physics, University of Osaka. The outgoing ejectiles were momentum analysed using the Grand Raiden magnetic spectrometer. Absolute cross sections were measured for states up to 7 MeV in excitation. Transferred angular momenta were identified through a comparison of angular distributions with those calculated using the distorted-wave Born approximation. Spectroscopic factors were extracted from the experimental cross sections. In addition to the 0v2B decay candidates the reaction was also performed on 128Te, 132Xe, 134Xe and 138Ba as a consistency check. The occupancies of the nuclei were determined from the spectroscopic factors, the reaction model was normalised using a common normalisation factor across all targets. The change in occupancies between the 0v2B decay candidates and their daughters were then determined. The change in occupancies were then compared with those calculated by interacting shell model, interacting boson model and quasiparticle random phase approximation. This comparison showed that whilst the three theories were qualitatively able to reproduce the change in occupancies, quantitatively there are significant discrepancies. These are the same models that are used to determine the nuclear matrix elements governing the rate of 0v2B decay.

The thesis presents a syntactic and semantic analysis of selected problems in the analysis of transitivity in English, Japanese and Korean in terms of a system of 'thematic relations' adapted from the work of Gruber and Jackendoff. The system is introduced in Chapter One. One way in which it differs from those of Gruber and Jackendoff is that their ambiguous notion of Theme is replaced by two separate notions - Theme and semantic subject. Verbs are classified into 'univalent verbs', which have a single set of thematic relations, and 'ambivalent verbs', which have more than one set of thematic relations. It is claimed that syntactic alternations such as that between 'spray x on y' and 'spray y with x' are a reflection of the ambivalence of the verbs in question. Chapter Two reviews discourse approaches and semantic approaches to Dative-shift. On the basis of a comparison of English and Korean it argues that Dative-shift in these two languages is clearly a semantic process rather than pragmatically motivated. Moreover, like the 'spray' type alternation, Dative-shift is shown to be a reflection of the ambivalence of verbs expressing a change in possession. Chapter Three is devoted to double-nominative constructions in Japanese and Korean, which in the past have been considered to be syntactically and semantically equivalent. A careful study of data from the two languages shows that the double-nominative constructions in Korean are not homogeneous but are divided into two classes with distinct thematic relations, one of which is lacking in Japanese. Chapters Four and Five discuss the passive in Japanese and Korean, respectively, and propose a new classification of passives in the two languages. Three types are recognized: the passive of interest, the anti-causative passive and the attributive passive. Finally, Chapter Six presents some typological observations concerning the passive and Dative-shift. In particular, the English passive and the passives of Korean and Japanese are compared with regard to their relation to Dative-shift, and it is argued that Dative-shift and the passive are, in principle, independent grammatical processes.

Master of Science / Department of Agronomy / Dallas E. Peterson / Auxin herbicides have been widely used for broadleaf weed control since the mid-1940’s. With new auxinic herbicide-resistant traits in corn, soybean, and cotton, use of these herbicides is likely to increase. Glyphosate-resistant Palmer amaranth (Amaranthus palmeri) and common waterhemp (Amaranthus rudis) are two primary problematic weed species that will be targeted with dicamba and 2,4-D in the new systems. No-till double-crop soybean after winter wheat harvest is a popular cropping system in central and eastern Kansas, however, management of glyphosate resistant Palmer amaranth has become a serious issue. Field experiments were established near Manhattan and Hutchinson, KS, in 2016 and 2017, to compare seventeen herbicide treatments for control of Palmer amaranth and large crabgrass (Digitaria sanguinalis) in dicamba/glyphosate resistant no-till double-crop soybean after winter wheat. Herbicide programs that included a residual preemergence (PRE) treatment followed by a postemergence (POST) treatment offered greater Palmer amaranth control 8 weeks after planting when compared to PRE-only, POST-only and burndown-only treatments. All treatments that contained glyphosate POST provided complete control of large crabgrass compared to less than 43% control with PRE-only treatments. Soybean grain yield was greater in programs that included PRE followed by POST treatments, compared to PRE-only and burndown-only treatments. A second set of field experiments were established in 2017 near Manhattan and Ottawa, KS to evaluate dicamba and 2,4-D POST efficacy on Palmer amaranth and common waterhemp. Five rates of dicamba (140, 280, 560, 1121, and 2242 g ae ha⁻¹) and 2,4-D (140, 280, 560, 1121, and 2242 g ae ha⁻¹) were used to evaluate control of the Amaranthus spp. Each experiment was conducted twice at each location. Dicamba provided better Palmer amaranth and common waterhemp control than 2,4-D across the rates evaluated. Control of Palmer amaranth was 94% and 99% with dicamba rates of 1121 and 2242 g ae ha⁻¹, respectively, but 2,4-D never provided more than 80% control at any rate. The highest rates of both dicamba and 2,4-D provided greater than 91% common waterhemp control, but control was less than 78% with all other rates of both herbicides. Palmer amaranth and common waterhemp control did not exceed 73% with the highest labelled POST rates of either dicamba or 2,4-D. Auxinic herbicide-resistant traits in corn, soybean, and cotton offer new options for controlling glyphosate-resistant Palmer amaranth and common waterhemp, however proper stewardship is vital to maintain their effectiveness.

Estudos consagrados mostram que o desempenho do gráfico de XBARRA melhora em muito com o uso da amostragem dupla. Com base nestes resultados, este trabalho se dedica ao estudo das propriedades dos gráficos T2 com amostragem dupla para processos bivariados. Através de uma rotação dos eixos cartesianos é possível transformar as variáveis originais, que em geral são altamente correlacionadas, em variáveis independentes. Com as novas variáveis e trabalhando com coordenadas polares foi possível obter o número médio de amostras (NMA) que o gráfico proposto necessita para detectar uma alteração no processo. Por meio de comparações dos NMAs foi possível verificar que o gráfico de controle proposto é, na maioria das vezes, mais eficiente que os gráficos adaptativos em que o tamanho das amostras e/ou o intervalo entre retirada de amostras são variáveis. / Similarly to the X chart, the T2 chart is slow to detect small or even moderate process disturbances. Earlier studies have shown that the use of the double sampling procedure improves substabtially the X chart performance. Based on that, we propose here to study the performance of the T2 chart with double sampling applied to control bivariate processes. An appropriate rotation transforms the original bivariate variables, in general presenting high correlation, in independent variables. With these equivalent variables and working with polar coordinates, it was possible to obtain the average run length (ARL) that measures the effectiveness of the proposed chart in detecting a process change. By comparisons of ARLs it was possible to verify that the proposed control chart is, frequently, more efficient than the adaptive charts with variable sample size or variable sampling interval.
