Loos, Trina Jane. "Determining the Function of Nuclear Bmp4." BYU ScholarsArchive, 2010. https://scholarsarchive.byu.edu/etd/2586.
Full textAbstract:
Bone morphogenetic protein 4 (Bmp4) is a well known growth factor that regulates gene expression through the SMAD signaling pathway. Bmp4 is involved in many developmental processes and has been identified as an important factor in several cancers, including melanoma, ovarian cancer, and colon cancer. Madoz-Gurpide et al. recently observed Bmp4 in the nuclei of a minor percentage of cells in colon cancer tissues. In addition, our lab has recently discovered a nuclear variant of Bmp2 (nBmp2), the TGF-β family member most closely related to Bmp4. These observations led us to hypothesize that a nuclear variant of Bmp4 (nBmp4) also exists. The results of chapter one report the existence of a nuclear variant of Bmp4. nBmp4 is translated from an alternative start codon downstream of the signal peptide sequence which allows a bipartite nuclear localization signal to direct translocation of nBmp4 to the nucleus. Chapter 2 and 3 further report that nBmp4 interacts with several subunits in the SCF E3 ubiquitin ligase, namely two Regulator of Cullins (ROC) proteins, five Cullin proteins, and two F-box proteins. Due to the known role of the SCF E3 ubiquitin ligase in regulating the cell cycle, the effect of nBmp4 on cell cycle progression was analyzed and the results show that nBmp4 affects the cell cycle by causing cells to accumulate in G0/G1. The association of nBmp4 and the SCF E3 ubiquitin ligase components and the affect that nBmp4 has on the cell cycle suggest that nBmp4 functions in the nucleus by inhibiting the SCF E3 ubiquitin ligase from ubiquitinating target proteins that are involved in regulating cell cycle progression. Finally, the initial stages in the generation of an nBmp4 over-expression mouse are described. The results of this research clearly change the traditional paradigm that Bmp4 performs all of its functions via extracellular signaling and introduce the existence of a nuclear variant that is involved in cell cycle regulation.

Esta dissertação possui como objetivo explicar sociologicamente a transição na vanguarda estética do campo do Rock. Entre 1967 e 1977, o campo do Rock conheceu os períodos de maior sucesso comercial e de prestígio primeiramente do Rock Progressivo e em um segundo momento do Punk Rock. Que motivos sociológicos explicam esta transição? Considera-se aqui que a arte não é uma esferada ilhada e separada do restante da sociedade. Por outro lado, a arte pode possuir, sim, um aspecto mais autonônomo entretanto os desenvolvimentos nos campos artísticos são mediados pelos desenvolvimentos sociais mais gerais. É fundamental para este trabalho a noção de campo de Bourdieu. Se as transições nos campos artísticos são perpassados pelos desenvolvimentos sociais mais gerais isto quer dizer que cada movimento ou vanguarda artística tem de lidar necessariamente com o seu período histórico e com as condições materias objetivas de produção e do capital. Esta preocupação com a estrutura econômica é tratada com base no trabalho do téorico Fredric Jameson. Há uma preocupação em demonstrar desenvolvimentos micro sociais, entretanto estes desenvolvimentos são reconectados aos desenvolvimentos sociais mais gerais. Portanto as sociaibilidades, valores e sentimentos que se desenvolvem entre os atores do campo do Rock e que são analisados neste trabalho são limitados por uma situação objetiva comum de cada tempo histórico. Como conclusão procura-se demonstrar que cada tempo histórico, Modernidade e Pós-Modernidade e cada lógica cultural correspondente modernismo e pós-modernismo mediaram os desenvolvimentos no campo do Rock. ______________________________________________________________________________ ABSTRACT
This work has as main objective to explain in sociological terms the transition in the aesthetics vanguard of the Rock field. The Rock field experienced between 1967 and 1977, first the apogee of Progressive Rock and then the apogee of Punk Rock. Which sociological concepts do explain this transiton? It´s considered in this work that art is not a separated island from the rest of society. The fields of art may be autonomous in a certain way but, this autonomy is not self complet, this means that the developments in the artistic fields are mediated by the social developments in general. It is fundamental for this work the notion of field as conceived by Bourdieu. If the developments in the artistic field are transpassed by the more general social developments, this means that every artistic vanguard has to deal, necessarily, with his historic time and with the material condition of a certain given time. This concern about the economic structure is analysed according the work of the theorist Fredric Jameson. There is a concern about micro social developments, but these developments are reconected to the social developments in capital and society. So, the sociabilitys, values and feelings among the actors of the Rock field are limitades by a given situation of each historic time. As conclusion, I intend to demonstrate that each historic time, Modernity and Post Modernity and each corresponding cultural logic, modernism and post modernism have mediated the developments in the Rock field.

Melendez, Elisa M. "For Those About to Rock: Gender Codes in the Rock Music Video Games Rock Band and Rocksmith." FIU Digital Commons, 2018. https://digitalcommons.fiu.edu/etd/3685.
Full textAbstract:
This dissertation explores gender codes within the intersection of two American pop culture staples, video games and rock music, by conducting a feminist analysis of two video games (Rock Band and Rocksmith). Both video games and rock music have had their share of feminist academic critique: Musicologists point out how lack of canonical inclusion, gendered attitudes towards instruments, and messages from supporting media create an unwelcome environment for women to pursue a rock music career. Game studies scholars have examined similar attitudes, including a lack of women represented in both the video games and the studios that create them.
Through a mix of creator and player interviews, participant observation, content analysis, and autoethnography, I look at the intersection of these two literatures (the rock music video game) to see how gender is hard-coded into the game, and what opportunities, if any, exist for subversion of societal and industry gender norms. Through not just looking at the game as text, I present a more “thick description” of a video game that takes into account the creators of the games, the players that play them, and a researcher that occupies multiple identities within the space. I argue that, in an effort to replicate an authentic rock musician experience in a video game, Rock Band and Rocksmith often replicate a lot of these gendered messages. The games’ text and set list emphasize a male-centric rock music canon. Rocksmith’s original whiskey-soaked visual design and marketing skew heavily towards an older male demographic. However, resistances to these codes exist in both the players who defy expectations by showing up to perform and compete, as well as the creators who actively work to make these games more inclusive via changes to future games as well as inclusive hiring practices, marketing, and music sourcing (with varying degrees of success).

Full textAbstract:
The hydro-mechanical effects of high pressure fluid injections into jointed rock are considered mostly in the context of Hot Dry Rock (HDR) geothermal energy systems. In Part I, the mai n aspects ari sing from the HDR research at the "Camborne School of Mines (CSM) and Los Alamos Nat iana 1 Laboratory (LANL) projects are reviewed. Previous approaches to fluid-rock interacti ons at these projects and important observed phenomena are highlighted. Fundamental aspects of rock joint geometry, mechanical behaviour and flow regimes within jointed rock are also reviewed. These aspects are then related to possible conditions in HDR systems. The role of in situ stress conditions is of great significance in this study and is reviewed theoretically and in detail for both the CSM and LANL project sites. The revi ew incl udes a comprehensi ve seri es of measurements, by different techniques, organised and interpreted by the author at the CSM project. In Part II, model development, the emphasis is on intermediate fluid pressures which are too high for simple diffusion alone and too low for tensile hydraulic fracturing. The dominant mechanical activity is one of joint shear. Strike-slip shearing due to fluid injection is examined in two dimensions with the numerical model FRIP, which has been extended by the author. Similar behaviour is examined in three dimensions with an analytical model which is linked to microseismic observations. This model explains the observed phenomenon of downward shear growth. Joint distribution and mechanical properties, and their effect on fluid diffusivity, are examined and used in analytical models of fluid pressure pulse propagation, tracer transport, and rock stress increment transfer. All models are used to help interpret field data, mainly from the CSM project. The models are also of potential application to hydrocarbon reservoir stimulation, liquid waste disposal and leakage from high pressure water tunnels.

Full textAbstract:
After the release of Nirvana's Nevermind in 1991, previously underground alternative rock burst into the mainstream and dethroned heavy metal as the dominant form of hard rock. The culture that surrounded alternative music was a politically progressive American post-punk movement that sought a more egalitarian, tolerant, and democratic world than heavy metal offered. Alternative culture saw heavy-metal style as a symbol for the masculinist values that seem to underlie the genre. Heavy-metal guitar gods—hyper-masculine virtuosic figures revered by fans for their "cool kid" personas and ability to "shred" the guitar—seemed sexist, arrogant, and apathetic. To oppose heavy metal's hierarchy, alternative rockers fashioned a contrastive aesthetic style in order to signify their democratic values. For Nirvana, doing so meant "killing" the guitar god by creating compelling hard rock without shred and satirizing the guitar god's "glam" appearance, thus rendering them impotent. Although alternative rock was generally suspicious of virtuosic display, several virtuosos took part in the genre including bassist Les Claypool of Primus, electric guitarist Tom Morello of Rage Against the Machine, and acoustic guitarist Ani DiFranco. These alternative musicians share many characteristics with virtuosos of other genres. Yet, that which most distinguishes alternative virtuosos from other kinds is the "loser" persona types they embody. Furthermore, unlike guitar gods, alternative virtuosos were understood to put their virtuosity in the service of something greater than themselves: alternative politics. Taking a dialogical approach involving a cultural semiotic analysis of various sonic, visual, and verbal styles that construct virtuosity and its meaning within the context of the alternative genre, this study demonstrates how alternative virtuosos fashioned virtuosic styles that could express alternative values.Après la parution de l'album Nevermind du groupe Nirvana en 1991, le rock alternatif auparavant “underground” a émergé sur la scène musicale traditionnelle, détrônant le heavy metal en tant que forme dominante du hard rock. La culture entourant la musique alternative se voulait un mouvement post-punk progressiste américain, qui recherchait un monde plus égalitaire, tolérant et démocratique que celui offert par le heavy metal. La culture alternative a perçu le style heavy metal comme le symbole des valeurs masculinistes qui semblaient sous-tendre le genre. Les dieux de la guitare heavy-metal—des figures virtuoses hyper-masculines adulées par les fans pour leur personnalité "décontractée" et leur abilité à faire du shred avec leur guitare—semblaient sexistes, arrogants et apathiques. Afin de s'opposer à la hiérarchie du heavy-metal, les rockeurs alternatifs ont développé leur propre style esthétique afin de démontrer leurs valeurs démocratiques. Pour Nirvana, ceci signifiait "tuer" les dieux de la guitare en créant un hard-rock irrésistible sans shred et en satirisant l'apparence "glamour" des dieux de la guitare, les rendant ainsi impotents. Les dieux de la guitare heavy-metal—des figures virtuoses hyper-masculines adulées par les fans pour leur personnalité "décontractée" et leur abilité à faire du shred avec leur guitare – semblaient sexistes, arrogants et apathiques.

Pour Nirvana, ceci signifiait "tuer" les dieux de la guitare en créant un hard-rock irrésistible sans shred et en satirisant l'apparence "glamour" des dieux de la guitare, les rendant ainsi impotents. Bien que le rock alternatif demeure généralement méfiant envers les démonstrations de virtuosité, plusieurs virtuoses ont pris part à ce genre musical, incluant le bassiste Les Claypool du groupe Primus, le guitariste électrique Tom Morello de Rage Against the Machine, et la guitariste acoustique Ani DiFranco. Ces musiciens alternatifs partagent plusieurs caractéristiques avec les virtuoses issus d'autres genres musicaux. Pourtant, ce qui distingue le plus ces virtuoses alternatifs d'autres catégories de virtuoses est la personnalité de "perdant" qu'ils incarnent. De plus, contrairement aux dieux de la guitare, il était établi que les virtuoses alternatifs mettaient leur virtuosité au service de quelque chose de plus grand qu'eux-même: la politique alternative. Empruntant une approche dialogique se fondant sur une analyse sémiotique culturelle de plusieurs styles soniques, visuels et verbaux construisant la virtuosité et son sens dans le contexte du genre alternatif, cette étude démontre que les musiciens alternatifs ont façonné des styles virtuoses de manière à exprimer des valeurs alternatives.

Esta dissertação investiga a adaptação da peça A Tempestade, de William Shakespeare, para o álbum Aqua, lançado em 2010 pela banda brasileira de heavy metal Angra. A trajetória histórica da peça nos últimos séculos sofreu impactos políticos e teóricos com a ascensão do pós-colonialismo. Em 1950, Octave Mannoni desencadeou, em Psychologie de la colonization, crescente atenção à peça Shakespeareana em cenários onde ideologias anticoloniais estavam por emergir, como a África e o Caribe. De forma análoga, George Lamming apropriou Shakespeare a perspectivas pós-coloniais com sua coleção de ensaios intitulada The Pleasures of Exile (1960), com sua (re)interpretação dos personagens Próspero e Caliban. O álbum Aqua, através do uso de mecanismos de adaptação específicos, tais como elementos melódicos, letras e material paratextual, aborda diferentes temas, personagens e situações da peça, ao mesmo tempo em que adentra questões pós-coloniais. A adaptação musical desenvolve, na canção "A Monster in Her Eyes", uma releitura da relação entre Próspero e Caliban, que ressoa com a teoria crítica pós-colonial, subvertendo a representação de Caliban como um monstro e resguardando sua soberania nativa. Relações dialógicas entre a peça e o álbum são traçadas com o suporte de A Theory of Adaptation, de Linda Hutcheon, no intuito de analisar os meios de expressão por trás do fenômeno de adaptação musical, que apropria obras adaptadas para diferentes públicos e contextos espaciotemporais.
Abstract : The present thesis investigates the adaptation of William Shakespeare?s The Tempest into the music album entitled Aqua, released by the Brazilian heavy metal band Angra in 2010. The historical trajectory of the The Tempest throughout the last centuries underwent political and theoretical impacts with the rise of postcolonialism. In 1950, Octave Mannoni unleashed, with Psychologie de la colonization, the sparkle for an increasing attention to the play in places where anticolonial ideologies would soon emerge, noticeably Africa and the Caribbean. Similarly, George Lamming approached Shakespeare in the light of postcolonial perspectives with his collection of essays entitled The Pleasures of Exile (1960), a (re)interpretation of The Tempest that focuses on its characters Prospero and Caliban. Angra?s music album Aqua, through the usage of its specific adaptation apparatuses such as melodic elements, lyrics, and paratextual material, addresses different themes, characters, and situations from The Tempest while bringing a postcolonial perspective to the fore. Moreover, the musical adaptation provides, with the song ?A Monster in Her Eyes?, a reinterpretation of the relationship between Prospero and Caliban which resonates with postcolonial critical theory, subverting the depiction of Caliban as a monster and giving voice to his claim as a native sovereign. This theoretical interplay is analyzed under the light of Linda Hutcheon?s A Theory of Adaptation as a means to observe the means of expression behind the musical adaptation phenomenon, channeling the adapted works to alternative publics, settings, and temporal contexts.

Full textAbstract:
Do you know that feeling? That feeling when the music you are listening to a concert or a new record and it just seems right? When you think, that’s it! That’s what music should sound like! When the music seems to touch your soul or mirror it, or…. something. And when you feel that, nothing else seems to exist and you are purely experiencing the music. My thesis work explores the way in which we try to capture this ephemeral moment of pure experience in order to keep it with us to revisit at our leisure. This, however, is a futile endeavor. No matter how many photos you take, records you collect, or days of music on your iPod, that initial feeling, that visceral experience, cannot be replicated. In this work I use both materials that evoke this idea of the ephemeral (transparent plastic and glass) and materials are ephemeral themselves (water and wax) to convey the inability to capture music and the feelings it evokes in us. I have also chosen to add elements to the space, such as a wooden floor, stage lights, and fabric panels, to suggest a performance stage or sound studio and to further this connection to the music which the work was inspired by.

Full textAbstract:
Rock Mass behavior and Cap Rock Stability at the Malmberget MineThe LKAB Malmberget mine is mined using sublevel caving. This mining method requires continuous caving of the hangingwall, which also result in ground deformations on the surface. The Malmberget mine is located in the municipality of Malmberget; thus well planned residential relocations have been required as the caving area has expanded and associated ground deformations developed. This thesis aims to bring an increased understanding of the stress redistribution and likely failure mechanisms in the hangingwall of the Printzsköld orebody, one of the orebodies currently in production in Malmberget. Rock mass investigations have been conducted in the Printzsköld and Fabian orebodies to gain more understanding of the rock mass. These investigations included core logging, strength testing, borehole photography, joint mapping underground, and rock mass characterization in the Printzsköld orebody. The investigations showed that rock mass rating (RMR) scatter for Printzsköld and Fabian orebodies were 55 – 78 and 40 – 76 respectively, indicating a fair to good rock mass, albeit with some scatter and weak units present. The work also showed that there were three main joint sets in both the Printzsköld and Fabian orebodies. Conceptual continuum and discontinuum numerical analysis was conducted for the Printzsköld orebody, in order to study potential failure behavior of the hangingwall and cap rock, as well as to study the possible effects of large-scale structures inferred near the Printzsköld orebody. The results from the continuum analyses indicated high stress build-ups in the crown pillar and stress relaxation in the hangingwall of the orebody. Both shear and tensile failure were noted in the hangingwall and the cap rock. As mining proceeded to the level of 1225 meters, the stresses in the cap rock increased and the relaxation zone also increased. The hangingwall of the Printzsköld orebody can be considered as a beam fixed at the crown pillar and the cave bottom. Shear failure in the cap rock had the potential to cause failure in the hangingwall and this beam effect of the hangingwall lengthened. A parametric study of the strength parameters was conducted, which showed that lowering cohesion had a larger effect on the stress build-ups in the cap rock and destressing in the hangingwall than lowering other parameters such as tensile strength and friction angle.The discontinuum model results indicated that the presence of large-scale structures reduced the stress build-up in the crown pillar and that slip developed along these structures. A reduction in the angle of friction for the structures resulted in more slip, compared to a reduction in cohesion. The presence of large-scale structures did not affect the yielding pattern in the rock mass or the far field stress redistribution in the hangingwall and cap rock.Keywords: Strength parameters, hangingwall failure, cave propagation, failure mechanism, large-scale structures, crown pillarGodkänd; 2014; 20141009 (sraban); Nedanstående person kommer att hålla licentiatseminarium för avläggande av teknologie licentiatexamen.

Full textAbstract:
Trata-se de uma análise da literatura de inspiração religiosa-cristã sobre o movimento rock, identificando no seu discurso os preceitos éticos-religiosos que fundamentam uma estética condenatória da música rock. A revisão da literatura sobre o rock aponta dois grupos bem distintos quanto ao seu posicionamento estético-ideológico. De um lado, os estudiosos em geral, que aceitam o rock como um movimento capaz de representar a cultura jovem, uma música associada a uma manifestação social normal e no campo oposto estão os religiosos - pastores, conselheiros e professores - que consideram o rock como uma música perigosa e com influência destruidora sobre a juventude. Esta dupla conotação ligada ao rock gerou a idéia deste estudo, tendo em vista os seguintes objetivos: 1) Apresentar uma revisão crítica da bibliografia de inspiração religiosa-cristã sobre o rock; e 2) Tentar encontrar respostas aos questionamentos quanto aos efeitos negativos desta música através da análise da relação música rock/ouvinte. A dissertação compõe-se de três partes que correspondem aos três capítulos do trabalho. O primeiro, aborda o rock sob a visão da literatura religiosa, que é a que condena a prática dessa música, e considera o porquê dessa condenação. O segundo capítulo, por sua vez, analisa o tema na concepção da literatura não-religiosa com uma avaliação comparativa com os tópicos do capítulo anterior. Por fim, o terceiro capítulo, apresenta os resultados da pesquisa de campo, realizada no ROCK IN RIO II - Rio de Janeiro no período de 22 a 24 de janeiro de 1991 - onde se contextualiza, na prática musical do rock, opiniões, conceitos e fatos apresentados nos capítulos anteriores. Conclui-se que o discurso condenatório ao rock representa uma disputa de poder pela qual os religiosos querem assegurar a lealdade dos membros da comunidade cristã a seus princípios. Neste sentido, o rock representa uma ameaça porque a sua missão, segundo a sua literatura e filosofia, é não copiar o mundo em seu estilo de vida e preferência musical. No entanto, através do estudo da literatura não-religiosa e da pesquisa de campo observou-se que esta música é um reflexo da sociedade e cultura atual e que, a maioria dos problemas apontados pela crítica religiosa-cristã no rock, são resultado de fatores extra-musicais.This thesis deals with an analysis of religious-christian literature concerning the rock movement which identifies religious ethical norms that condemn rock music. This literature points to two different groups regarding their ideological position. One group accepts rock as just a cultural movement associated with young people. The other, mainly religious and clergymen, consider rock music to be dangerous with a destructive influence on the youth. These two stands generated the basic idea of this research along with the following objectives: 1) To present a critical analysis of the bibliography related to the religious-christian viewpoint dealing with rock; 2) To discuss the negative critique to this music by means of an analysis of the relation rock music/listeners. The thesis is divided into three chapters: the first indicates very strong condemnation of this music by much of the religious literature and why so. The second one is a comparative of the topics presented in the first chapter by using non-religious literature. Finally, the third chapter shows the results of field work done at the "Rock in Rio II Festival" in Rio de Janeiro, 1991. Much of what was presented in the previous chapters is discussed vis a vis data gathered at that event. It can be concluded that the discussion dealing with the condemnation of rock represents a dispute of power by which those of a religious background desire to maintain the loyalty of the christian community to its principles. In this way, rock appears to be a threat to them because their mission, acording to their literature and philosophy, is not to copy the world in its life style and its musical preference. However, research dealing with non-religous literature revealed that this music is a reflection of the society and its current culture. Also, this literature leads to conclude that many of the problems pointed out by the religious critics concerning rock music are effected by non-musical factors.

Full textAbstract:
To date there are no published studies that quantify the amount of dehydration that takes place during rock climbing (RC). The purposes of this study were to determine whether significant dehydration occurs during a simulated RC session and whether ad libitum water ingestion augments this dehydration. In order to do so, eight male (Mean±SD; 26.5±5.8) and two female (24.0±1.4 yrs) experienced rock climbers completed two identical 115-minute RC trials on a motorized indoor RC treadmill, which consisted of six 15-minute RC intervals with a five minute rest between each interval. One trial the subjects did not receive water (NH) the other they ingested water ad libitum during the rest periods (AL). Percent change in body mass (%DeltaBM) and percent change in plasma volume (%DeltaPV) were calculated for both trials. Urine specific gravity (USG), rhythmic hand grip endurance and plasma creatine kinase were collected before and after both trials. Heart rate and rating of perceived exertion (RPE) were measured throughout both trials. Data was analyzed via RMANOVA, Wilcoxon signed-rank tests and paired T-tests. The level of significance was set at P≤0.05. There were significant differences between trials for %DeltaBM (Mean±SE: NH=-2.4±0.1%, AL=-0.9±0.2%) and %DeltaPV (NH=-2.93±2.42%, AL=+8.76±3.24%). Heart rate and RPE significantly increased during both trials. There was a significant interaction between trials for HR. No other significant differences between trials were observed.

Full textAbstract:
This thesis identifies the geotechnical parameters of the Antalya karstic foundation rocks
(travertine/tufa), which are highly variable in nature, by means of geological observations,
geotechnical site investigations, and field and laboratory geomechanics tests to examine
karstic (mainly tufa) rock mass behavior. Several geotechnical parameters such as
porosity, seismic wave velocity, uniaxial compressive strength, Young&rsquos modulus, tensile strength, etc. that are thought to have significant influence on rock mass behavior have been tested and statistically analyzed. Principal component analysis and multiple linear and non-linear regression analyses have been carried out in order to reveal correlations between the geotechnical parameters tested. Porosity has been statistically determined to be one of the major parameters governing the strength of the Antalya tufa rock mass. Intact rock failure criteria, among which Bieniawski&rsquo
s criterion has been proven to be more appropriate for each tufa type (phytoherm framestone, phytoherm boundstone, microcrystalline tufa, phytoclast tufa and intraclast tufa) along with the Antalya tufa rock mass have been determined from the experiments. GSI rock mass classification of the Antalya tufa rock mass, whose GSI value was recommended between 20±
5 and 75±
5, has been attempted to be used in engineering design. Furthermore, the depth and dimension of the karstic cavities and fractures have been investigated by the geophysical tests, surface geological survey and subsurface investigations (borings and observation pits).

Full textAbstract:
The work carried out in this thesis outlines some of the problems associated with abrasive wear in machines and other mechanical equipment used to excavate or process natural rock material. It has been stated that if the problems associated with abrasion are to be better understood, then a sound knowledge of the abrasive potential of rocks is essential. A number of common wear mechanisms are described together with existing hardness and abrasive tests. The author has investigated rock hardness and abrasiveness by the use of existing methods and subsequently, developed new correlated with the well tests which can be established methods of determining physical and mechanical properties of rock. A project on hard rock drilling has been conducted to determine the rate of wear on expensive diamond impregnated coring drill bits. A detailed investigation which involved the design and manufacture of special measuring equipment to accurately measure and record changes in the profile shape of the bit during its life span. This has permitted a study of the wear characteristics related to the various drilling parameters employed. A collaborative project was carried out with DeBeers, UK, to attempt to discover methods of predicting the rate of specific wear on diamond impregnated saw blades and the cutting forces required with the sawing of hard stone materials. This project has led to a new statistical approach to the analysis of the acquired test data for this purpose. A number of case histories have been discussed and recommendations made. As a result of these investigations together with the work covered in this thesis, the author has developed two new abrasive tests. These tests can be used to test materials such as unconsolidated rocks which otherwise, could not be satisfactorily tested by the established tests already in existence. The new tests have been tried and proved by correlating the test data by combining multiple regression analysis with the results obtained from physical and petrological rock property tests with actual rock cutting data. Conclusions have been drawn and recommendations for future work suggested.

Full textAbstract:
Memoria académica para optar al título de PeriodistaEl fenómeno del rock latino representa un hito excepcional dentro de los anales de la música contemporánea. Desde principios de la década de los ’80 y en medio de las dictaduras militares de Argentina y Chile se albergó un prolífico movimiento musical que rápidamente se extendió por el resto del continente. Si bien es cierto, en ambos países el proceso tiene características muy similares, es posible establecer como uno de los puntos primigenios, la censura impuesta en Argentina para la difusión de música en inglés debido a la Guerra de Las Malvinas (1982). A partir de ese momento y casi como un efecto dominó, el rock abre sus banderas de lucha ante el régimen político y desde Argentina irrumpe abruptamente en nuestro país, hacia 1984. Pero nuestra escena rockera no era una página en blanco. Ya existía un claro precedente musical de la mano del llamado “Canto Nuevo”, cuna de grandes figuras nacionales (Hugo Moraga, Eduardo Gatti, “Los Jaivas”, “Quilapayún”, etc.) y nuevos espacios de difusión (“Café del Cerro”, “Teatro Caupolicán, “Teatro Cariola”, etc). Asimismo, los rockeros nacionales tenían a sus principales exponentes en grupos como : “Tumulto”, “Arena Movediza”, “Millantún”, “Sol y Medianoche”, entre otros. Los medios de comunicación locales vivían un tiempo de censura y la radio, aparece como un bastión fundamental para la difusión de este semillero artístico. Surgen dos nombres importantes: Radio Chilena y Radio Galaxia. La primera de ellas difundió gran parte del material del Canto Nuevo, gracias al programa “Nuestro Canto”. La segunda, se convirtió en uno de los principales soportes del rock en español a través del programa “Hecho en Chile” , conducido por Sergio “Pirincho Cárcamo”. Frente a este espectro nacional, entre 1984 y 1985, Chile consume la producción discográfica de rock argentino correspondiente a cinco años. Llegan a nuestra palestra radial, nombres como : Charly García, Celeste Carballo, “Virus”, “Miguel Mateos”, “Los Enanitos Verdes”, “G.I.T.”, entre muchos otros. La camada rockera argentina aterrizó estrepitosamente apoderándose fuertemente de los gustos populares. En medio de aquella maraña musical, surge un nombre poderoso: “SODA STEREO”. Trío bonaerense que meteóricamente saltó a los primeros lugares cantando “Te hacen falta vitaminas” y “¿Por qué no puedo ser Jet?”, de su disco homónimo (1983).

Full textAbstract:
Popular music and film are separate media, framed by specific discourses, histories of
distribution and reception, semiotic relationships and literacies. Through these divergent
manifestations and ideologies nodes of convergence exist. At moments of connection,
new and innovative textual and contextual possibilities emerge, transforming the ways in
which audiences both engage and read these media. Whilst often driven by capitalist
goals, both popular music and film capture and tether personal expression and collective
memory. Through these processes of signification, popular cultural texts belonging to
both media forms are able to resist their commodified origins to inform and construct
both collective and individual identities.
This thesis charts the movement of popular music across cinema. RocknRoll is utilized
not only as an amalgam of texts made up of sounds and images, but also as a critical and
interpretative apparatus through which specific cultural identities are configured. This
work is concerned with various manifestations of political resistance in popular culture,
and the ways in which this resistance is moderated through cultural commodification.
Using an interdisciplinary approach converging film analysis, popular music studies
and music journalism this thesis constructs an ideological framework through which
film and popular music can be aligned, and through which this alignment can be
researched.
Through an engagement with myriad cinematic and popular cultural texts, executed through interdisciplinary methods, this thesis establishes a theoretical framework for
understanding and analyzing the convergence of popular music and cinema. Its original
contribution to knowledge is an evaluation of the ways in which these media are changed
through their alignment and how they inform each other both structurally, as tangible
manifestations of specific media codes and structures, and politically, in the ideological
embodiment of particular identities and representational realities. This goal is achieved
through the selection of specific research materials, especially those which have not been
subject to detailed investigation in other scholarly studies. Specific filmic and musical
texts are discussed because they embody the aesthetic and political synergy of these two
media forms as well as demonstrating the cultural processes through which this synergy
is enacted.
This thesis offers interdisciplinary dialogue as a valid strategy to understand the
processes involved in the creation and reception of texts which are cinematic in nature
but utilize the language and discourse of popular music. The textual and contextual
manifestations of this process are a primary concern. Emphasis is placed on the
implications for film form in terms of the structure of texts and their existence within
specific genres, the shifting position of the auteur and the renegotiation of the term and its
meaning to film and popular music, and the conjunction and interaction between
creativity and commerce. In addressing the political and aesthetic possibilities of the film
and popular music hybrid, as well as the cultural implications of their convergence, this
thesis provides new perspectives for the analysis of both forms.

Full textAbstract:
In fractured rocks of low permeability, the hydraulic properties of the rock mass are strongly influenced by the connectivity and fracture geometry of the fracture system, the stiffness and deformational properties of fracture surfaces and the geostatic stresses. This dissertation demonstrates through theoretical analysis the sensitivity of fracture connectivity and flow rate to fracture radius, fracture density and measurement scale. Percolation factor and percolation frequency are suggested as indices of connectivity and flow rate. Models of hydromechanical coupling, normal closure and simple geometrical joint systems are proposed to study fracture porosity and fracture permeability and are compared with measured values from published papers. Fracture surface characteristics are expressed as indices of JRC and JCS. The relation between fracture aperture and geostatic stress is also examined. Based on the percolation process, a three dimensional discrete fracture model with statistical parameters of fracture geometry is developed to investigate the relations between the connectivity and flow rate and the percolation factor and percolation frequency. This model has the capability to generate a fracture network and to solve for steady state flow. The flow through each fracture is discretized by the boundary element method. By performing numerical simulation, the percolation threshold was found to be in the range of 0.9 to 2.4 for orthogonal joint sets. There is a rapid increase in flow rate with increasing fracture density or fracture length as the percolation factor reaches the percolation threshold. The percolation factor and percolation frequency are scale-dependent. A fracture network with large fractures and a high fracture density has a high percolation frequency and a high percolation factor. A network with high percolation frequency and percolation factor has a high flow rate. A constitutive model linking the initial conducting aperture, mechanical conducting aperture, JRC, JCS, geostatic stress and fracture geometries can be used to predict fracture porosity and fracture permeability in terms of depth. Preliminary comparison with field data shows that models comprising three orthogonal sets and disc-type fracture models can be used to simulate observed behavior. Fracture porosity and fracture permeability based on a model of three orthogonal sets can be used to predict flow through volcanic rocks. For sedimentary rocks a model incorporating a model of three orthogonal sets and one parallel set can be used with varying levels of confidence.

Full textAbstract:
This work is based on the comparative iconographic analysis of a distinct corpus of paintings within the Later Stone Age, Bushman or San art of southern Africa. They are distinct from the rest of the paintings of the region in age, numbers, variety, complexity and density. It defines in detail the principles that determined the form of the paintings - where the primary concern was to depict objects through outline alone - and the canon - the very restricted range of subjects that were depicted. It demonstrates that the human imagery established a set of archetypes, expressing concepts of the roles of men and women in the community through a set of readily legible attributes. The art was thus in essence conceptual and, of its nature, not concerned with the individual, illustration, narrative, documentation or anecdote. Within this framework, the paintings focused on concepts of the various forms and degrees of supernatural energy or potency that all San have believed to be inherent in every person. Further studies demonstrate how large and dangerous animals, particularly the elephant, were conceived as symbols of potency and their hunting as a metaphor for trance. Compositions based on oval shapes and the dots within and emanating from them are shown to be further symbols of aspects of potency. Many recurrent and hitherto ignored motifs attached to human figures are shown to be a graphic commentary on the metaphysics of the archetypes. The study is set in the context of the archaeology of the sub-region, recent studies of San concepts, perceptions and beliefs, a review of previous research, and a critique of influential recent South African work which first integrated paintings with San beliefs.

Full textAbstract:
One of the main and most challenging environmental problems related to mining is the generation of acid rock drainage (ARD), a leachate characterized by low pH and elevated concentrations of sulfate, metals, and metalloids formed when sulfide-bearing minerals are subjected to oxygen and water. During the operation of a mine, waste rock is often deposited in heaps and usually left under ambient conditions, enabling sulfides to oxidize. Generated ARD is commonly treated actively with alkaline material in an attempt to raise the pH and precipitate metals, with subsequent formation of sludge, which requires additional treatment. To focus on the treatment of waste rock rather than the ARD could prevent the generation of ARD; reduce the lime consumption, costs, and sludge treatment. This thesis aims to identify and evaluate the potential of different industrial residues to maintain circumneutral pH in a sulfide oxidation environment, allowing secondary minerals to form on the reactive sulfide surface to prevent sulfide oxidation and generation of ARD. Five different industrial residues (blast furnace slag, granulated blast furnace slag, cement kiln dust, bark ash, and lime kiln dust) were selected in a feasibility study performed prior to this study. The selection was based primarily on their alkaline properties, availability, and early yield. The waste rock was selected due to its high content of sulfides (>50%) and potential to generate ARD. Initial characterization of the industrial residues included combining mineralogical and chemical composition with batch testing (L/S 10). Sulfide oxidation in the leaching of the waste rock accelerated after week 29 resulting in high concentrations of major elements such as Al, Fe and S but also extremely high concentrations of e.g. As, Cu, Mn, Pb, Sb and Zn despite their relatively low content in the waste rock. Leaching was conducted during 14-153 weeks. The initial characterization implied that all of the studied industrial residues has the potential to prevent ARD generation. However, the enrichment and leachability of Pb in the cement kiln dust, as well as Cr and Zn in the bark ash, suggested the presence of elements of potential concern that could limit the use of the materials. When the industrial residues were added to the waste rock surface in small-scale laboratory test cells, blast furnace slag, granulated blast furnace slag, and cement kiln dust self-cemented and failed to maintain circumneutral pH, whereas bark ash (1wt.%) prevented acidity, metal and metalloid leaching. However, the use of bark ash may prove problematic due to the release of Cl, K, and Na likely related to salt dissolution. Lime kiln dust (5wt.%), the most promising of the industrial residues, maintained a circumneutral pH throughout the time of leaching, with an overall decrease of metal and metalloid concentrations by more than 99.9%. Results from investigations of secondary minerals formed combined with element release during the leaching period suggest that the addition of LKD to the waste rock led to decreasing concentrations of S in the leachate due to decreased sulfide oxidation, which subsequently led to gypsum dissolution. Moreover, the addition of LKD to the waste rock generated a lower amount of secondary minerals compared to when no addition was made. The results from these studies increase the understanding of advantages and limitations of using selected industrial residues in the treatment of mine waste. Moreover, it shows that a rather small amount of alkaline material, corresponding to 4% of the net neutralizing potential of waste rock, can prevent the acceleration of sulfide oxidation and subsequent release of sulfate, metals, and metalloids. However, the quantity and long-term stability of the formed secondary minerals need to be evaluated and understood before this method can be applied at larger scale.

Full textAbstract:
The process of choosing a site for a nuclear waste repository means that many aspects have to be taken into consideration. One of these is that the repository has to be mechanically stable for a long time. The mechanical stability of the rock is very difficult to determine. One of several factors, which determine the mechanical stability, is the virgin state of stress. The thesis project consists of two parts. In the first part the state of stress at Äspö Hard Rock Laboratory had to be defined. This was done based on earlier rock stress measurements conducted during the years 1988 to 1997. Two different measurement techniques have been used, hydraulic fracturing and overcoring. During the overcoring two types of cells have been used, CSIRO HI-cell and a cell developed by the Swedish State Power Board (SSPB). In the second part of the project, investigation of the correlation between the stress and geological structures are made using numerical modelling tools such as FLAC, UDEC and 3DEC. The rock stress measurements using the hydraulic fracturing gave orientations of the horizontal stress that coincide with earlier hydraulic fracturing measurements conducted in Scandinavia. The magnitudes of rock stresses are slightly lower than the earlier reported stress magnitudes for the Scandinavian part of the earth crust. The rock stresses obtained from the overcoring resulted in higher stresses than what was predicted by the hydraulic fracturing measurements. However, the orientation of the maximum horizontal stresses coincides well between the two techniques. The orientation is also more or less constant with respect to increasing depth. The state of stress at Äspö is defined by using the results from the hydraulic fracturing and the measurements conducted by SSPB-cell. The measurements from the SSPB-cell are used since these have a Poisson's ratio that corresponds well with the uniaxial tests of rock samples and since the measurements have been done at a distance from the opening where no influence from the openings can be expected. Since the magnitudes of the rock stresses differ between overcoring and hydraulic fracturing, some efforts have been made to find possible causes for this. The rock stresses when conducting overcoring gave higher values overall, which could be explained by high Poisson's ratios and a minor influence from the opening as the stress measurements might have been done in the disturbed zone. The high Poisson's ratio may depend on the stress-induced microcracks, which might be initiated during the overcoring of the cell, during the drilling of the pilot borehole, in which the cell is installed, and during biaxial testing. Statistical analysis showed that there is significant differences between the mean values of Poisson's ratio obtained from biaxial tests of cores containing the CSIRO HI-cell and the SSPB-cell. Poisson's ratio is about 0.34 for CSIRO HI-cell while the SSPB-cell gave a Poisson's ratio of 0.23. The analysis also showed that Young's modulus does not differ between the techniques. The modelling in FLAC was made to simulate the overcoring and biaxial testing. The result show that it is possible to obtained extensional strain in the core during overcoring if the major principal stress is perpendicular to the borehole axis. This may lead to microcracking occurring in the core causing high Poisson's ratio, which results in higher stresses. It can also be seen from the simulation of the biaxial testing that extensional strain is achieved even if the hollow core is not damaged during overcoring. The analyses using UDEC was made to study the effect of different properties of a discontinuity, such as the dip angle, Young's modulus, Poisson's ratio, density and the normal and shear stiffness. The analyses showed that an inclined discontinuity affects the stresses especially if sliding occurs. So, the dip angle does not solely, determine the amount of disturbance of the state of stress around a discontinuity. If slip will occur or not depends, thus, on a combination of dip angle, friction angle and the far field state of stress. A dip angle of 30 degrees affected the major principal stress most, while the minor principal stress is most affected by a dip angle of 45 degrees, for a friction angle of 10 degrees. The results from the simulation of a thick zone showed that the elastic properties of the zone material mainly affect the stresses within the zone. However, higher values of Young's modulus and Poisson's ratio in the zone than in the side rock resulted in higher stresses within the zone than outside. The orientation of the major principal stress becomes more perpendicular to the zone. The 3-dimensional analyses using 3DEC was made in order to investigate if the stresses at Äspö could be correlated with the major geological structures. The results show that the increase in the horizontal stress seen both in KAS02 and KAS03 is obtained in the model when using a bilinear stress state that is based on the measurements performed at Äspö. However, a satisfying coincidence is not obtained with the measured stresses in KAS02, KAS03, KAS05 and KZXSD8HL, which were the boreholes used as reference boreholes. One of the reasons for the disagreement may mainly be that the discontinuities used in the 3DEC model are more or less vertical. The least dip angle used is 60 degrees. Another reason may be that the measured stresses are influenced by far more parameters than are used in the 3DEC- model, such as different rock types, smaller discontinuities and mineral grains.Godkänd; 2000; 20070316 (ysko)

Full textAbstract:
The main aim of this Thesis is to examine how the rock mass and intact rock properties influence the excavatability of rock in surface mine. One of the most important decisions in the design of surface mine is the selection of mine equipment and plant. Now that increasing effort is being invested in the design and manufacture of continuous surface miners it is appropriate to examine how their performance can be related to the physical properties of the rock mass and intact rock.Over the years many attempts have been made to develop a means of assessing the excavatability of rock. Most of them are based on an empirical rating system whilst some authorities still propose the use of seismic velocity as a direct predictor of the rippability of a rock mass. On the other hand there are a number of classical models which have been developed to define the cutting force required at the pick or tooth of continuous miners.Whilst these methods have been applied with various degrees of success to the design of excavation systems there is no generally acceptable method of defining the excavatability or cuttability of a rock mass in terms of the machine power required to generate a particular rate of production.An attempt is made to overcome this deficiency by recording the intact and rock mass properties at Limestone quarry in Retznei, Austria; Openpit Gold Mines in Meekatharra and Mt Gibson of Western Australia and Openpit Coal Mine in Air Laya, Indonesia, where VASM-2D and Bucket Wheel Excavator O&K SchRs(800/1.2)15 or O&K S630 were in use in the first mine sites and Air Laya respectively to use this data to examine the relationships between the relevant dimensionless groups developed from a dimensional analysis of the problem.The dimensionless groups are obtained by examining the factors which influence the productivity of a surface miner. These include intact rock and rock ++mass properties, and machine power required for a particular rate of production and lead to the development of dimensionless groups namely, Rock Cuttability Index (RCI), Rock Mass Factor (RMF), Brittleness Index (BI), Rock Excavatability Index. The monitoring of machine power was carried out at Mt. Gibson and Air Laya mines.As a part of this study, field seismic tests were carried out at Mt. Gibson and Air Laya with the intention of seeking the most appropriate method of this type of test and analysis for excavation purposes. The test results indicate that borehole tests are the most promising and the output of seismic velocity obtained from a built-in program seismograph needs further thorough examination.The analysis of field data at all the sites proved that the most appropriate measure of discontinuities in the rock mass is the mean distance between discontinuities in a direction parallel to the cutting direction of the machine.Since the lateritic rock mass is different to other ordinary rock masses, a modified RMR is proposed. This is done by adjusting classification criteria on spacing and condition of discontinuity. The results proved that the discontinuity spacing obtained from the proposed method warrants wide application of the power cutting model developed.The RMR, Q-System and Excavatability Index are used to assess the performance of the continuous surface miners investigated. The results indicated that the Excavatability Index is the most acceptable criterion for the excavatability assessment.The outcome of this research has confirmed the significance of the RCI as a predictor of cutting performance of mechanical machines. The relationship between the RCI and REI can be used to good effect in analysing the performance of operating machines. A good example of this is given in the analysis of the performance of the BWE at the Mae Moh mine in Thailand.

Full textAbstract:
The mixing of mine tailings and waste rock to form “paste rock” prior to disposal is now receiving significant attention from the point of view of sustainable mine waste management practice. This approach has been viewed as a favourable alternative to traditional methods of mine waste disposal because paste rock has the potential to overcome deficiencies, such as acid rock drainage and mechanical instability, associated with traditional methods of mine waste disposal. In consideration of the current limited understanding of the fundamental mechanical response, a systematic laboratory triaxial testing research program was undertaken on paste rock specimens prepared such that the tailings would “just fill” the void spaces between the coarse-particle skeleton. A new “slurry displacement” method was developed for reconstitution of saturated, uniform/homogeneous specimens of highly gap-graded paste rock for triaxial testing. Undrained cyclic triaxial tests indicated that reconstituted paste rock displayed “cyclic-mobility-type” strain development. Strain-softening accompanied by loss of shear strength did not manifest regardless of the applied cyclic stress ratio (CSR). The results suggest that the material is not likely to experience flow deformation under monotonic (static) and/or cyclic loading conditions at least up to the tested initial effective confining stress conditions of up to ≤400 kPa. The behaviour of paste rock was noted to be more similar to the behaviour of rock-only material than that of tailings-only material indicating that the rock skeleton mostly controls the shear resistance in “just filled” paste rock. This finding is in accord with the behaviour of paste rock observed from one-dimensional consolidation tests. In relative terms, paste rock has a higher potential for strain development under a given cyclic stress ratio and number of load cycles in comparison to tailings-only and rock-only materials. The presence of tailings in the pore space between the rock particles appears to decrease the ability of the rock particles to engage contact and develop inter-particle stresses in comparison to the case with rock-only material.

Full textAbstract:
Prior to an underground excavation a site investigation is carried out. This includes reviewing and analysing existing data, field data collected through outcrop mapping, drill core logging and geophysical investigations. These data sources are combined and used to characterise, quantify and classify the rock mass for the tunnel design process and excavation method selection. Despite the best approaches used in a site investigation, it cannot reveal the required level of detail. Such gaps in information might become significant during the actual construction stage. This can lead to; for example, over-break due to unfavourable geological conditions. Even more so, an underestimation of the rock mass properties can lead to unplanned stoppages and tunnel rehabilitation. On-the-other-hand, the excavation method itself, in this case, drill and blast, can also cause severe damage to the rock mass. This can result in over-break and reduction of the strength and quality of the remaining rock mass. Both of these attributes pose risks for the tunnel during excavation and after project delivery. Blast damage encompasses over-break and the Excavation Damage Zone (EDZ). In the latter irreversible changes occur within the remaining rock mass inside this zone, which are physically manifested as blast fractures. In this thesis, a number of methods to determine blast damage have been investigated in two ramp tunnels of the Stockholm bypass. Herein, a comparison between the most common methods for blast damage investigation employed nowadays is performed. This comparison can be used to select the most suitable methods for blast damage investigation in tunnelling, based on the environment and the available resources. In this thesis Ground Penetrating Radar, core logging (for fractures) and P-wave velocity measurements were applied to determine the extent of the blast damage. Furthermore, the study of the two tunnels in the Stockholm bypass shows a significant overestimation of the actual rock mass quality during the site investigation. In order to gain a more accurate picture of the rock mass quality, Measurement While Drilling (MWD) technology was applied. The technology was investigated for rock mass quality prediction, quantifying the extent of blast damage, as well as to investigate the potential to forecast the required rock support. MWD data was collected from both grout and blast holes. These data sets were used to determine rock quality indices e.g. Fracture Indication and Hardness Indicator calculated by the MWD parameters. The Fracture Index was then compared with the installed rock support at the measurement location. Lastly, the extent of the damage is investigated by evaluating if the MWD parameters could forecast the extent of the EDZ. The study clearly shows the capability of MWD data to predict the rock mass characteristics, e.g. fractures and other zones of weakness. This study demonstrated that there is a correlation between the Fracture Index (MWD) and the Q-value, a parameter widely used to determine the required rock support. The study also shows a correlation between the extent of the blast damage zone, MWD data, design and excavation parameters (for example tunnel cross section and charge concentration).

This research is carried out to better understand the nature of the rock mass and to have a better anticipation of rock fragmentation before blasting the rock mass. Current practices of assessing rock mass usually involve techniques that focus on the surface or outcrop of the rock mass such as scanline surveys, window surveys, photogrammetry and laser scanning etc. These techniques generally lack the ability of providing sufficient information about the rock mass as well as bear various inherent constraints such as safety issues, time requirements, user biasness, equipment requirements and reproducibility of results. Similarly, the rock fragmentation is predicted using different mathematical equations known as fragmentation models. However, these models ignore some key factors that significantly affect the nature of fragmentation such as chargeability of blastholes, drilling information e.g. borehole deviation and require numerous rock parameters which are not well known in most cases. These models are often site-specific and are mostly developed for surface mines. Therefore, their application in underground mining is not so common. The aim of this research is to investigate the possibility of eliminating the constraints and supporting the current practices of rock mass assessment and rock fragmentation prediction. In this regard, drill monitoring technique has been selected as a potential tool for analysing the rock mass and forecast the rock fragmentation. To test the selected technique, measurement while drilling (MWD) data was collected from three different mines. The variations in MWD data were analysed to identify different zones and structures present inside the rock mass. The results were compared to 3D images obtained by close-range terrestrial digital photogrammetry for validation, which showed a close agreement with each other. Similarly, MWD data was used to classify the rock mass into five different classes i.e. solid, slightly fractured, highly fractured, having cavities, and major cavities in a sublevel caving operation. The loading operation of the blasted rock was filmed and digital images of LHD buckets containing blasted rock were extracted from the video recordings. The blasted rock inside the buckets were categorized as fine, medium, coarse and oversize fragmentation based on their median fragment size (X50). A statistical analysis was carried out to see the correlation between MWD based rock mass classes and fragmentation classes. The results showed that fine and medium size fragmentation has better correlation and can be predicted with higher accuracy using MWD data as compared to coarse and oversize fragmentation. The results suggest that the drill monitoring technique has the potential to assess rock mass as well as predict rock fragmentation to some extent. It can be used to differentiate between a weak or strong rock mass or between a fractured or competent rock mass. It can be used to differentiate between joints, cavities or foliations etc. It can also be used to predict finer and medium size fractions of the blasted rock with reasonable accuracy. However, the coarser and oversize fragmentation didn’t have a reliable correlation with MWD data. The potential of using drill monitoring technique for rock mass assessment and rock fragment prediction can be further explored and validated using other established rock mass and fragmentation assessment techniques. It can largely overcome the time, cost and safety constraints associated with the methods already in practice.

Full textAbstract:
This thesis develops a novel understanding of the fundamental issues in characterising and propagating unpredictability in rock engineering design. This unpredictability stems from the inherent complexity and heterogeneity of fractured rock masses as engineering media. It establishes the importance of: a) recognising that unpredictability results from epistemic uncertainty (i.e. resulting from a lack of knowledge) and aleatory variability (i.e. due to inherent randomness), and; b) the means by which uncertainty and variability associated with the parameters that characterise fractured rock masses are propagated through the modelling and design process. Through a critical review of the literature, this thesis shows that in geotechnical engineering – rock mechanics and rock engineering in particular – there is a lack of recognition in the existence of epistemic uncertainty and aleatory variability, and hence inappropriate design methods are often used. To overcome this, a novel taxonomy is developed and presented that facilitates characterisation of epistemic uncertainty and aleatory variability in the context of rock mechanics and rock engineering. Using this taxonomy, a new framework is developed that gives a protocol for correctly propagating uncertainty and variability through engineering calculations. The effectiveness of the taxonomy and the framework are demonstrated through their application to simple challenge problems commonly found in rock engineering. This new taxonomy and framework will provide engineers engaged in preparing rock engineering designs an objective means of characterising unpredictability in parameters commonly used to define properties of fractured rock masses. These new tools will also provide engineers with a means of clearly understanding the true nature of unpredictability inherent in rock mechanics and rock engineering, and thus direct selection of an appropriate unpredictability model to propagate unpredictability faithfully through engineering calculations. Thus, the taxonomy and framework developed in this thesis provide practical tools to improve the safety of rock engineering designs through an improved understanding of the unpredictability concepts.

El tema de esta investigación es la definición ideológica del rock cristiano. En la discusión de las características “cristianas” o “mundanas” que generalmente se presenta entre los creyentes cristianos, suele percibirse cierto juego de franquicias ideológicas que tienen el propósito de recuperar los aspectos más relevantes para una adecuada reproducción social y/o cultural de la institución religiosa. En este sentido, el propósito nuestro es el conocimiento etnográfico de la definición ideológica del rock cristiano. Para esto, se ha optado por la utilización de una perspectiva interpretativa de la subjetividad en el rockero cristiano. Interpretación que se define teóricamente mediante las pautas epistemológicas propuestas por el antropólogo norteamericano Clifford Geertz. Así, pues, el objetivo principal está dirigido al conocimiento interpretativo del significado, que se entiende como la representación simbólica que el objeto asume en la subjetividad de los rockeros cristianos; pero, también, de la función, o sea, al empleo que se promueve del mismo objeto entre aquellos. De esta manera, la definición ideológica del rock cristiano se descubre en la explicación exegética que se tiene de su significado y/o función religiosa. Para el análisis de este objetivo, se ha visto por conveniente la consideración de un esquema de clasificación etnomusicológico que —así como fue postulado por Alan P. Merriam— debe enfocarse en la representación que la música tiene para un determinado grupo social y/o cultural. En este sentido, los objetivos secundarios están establecidos en los siguientes aspectos temáticos: a. instrumentos musicales; b. lírica de las canciones; c. clasificación de la música; d. papel y categoría de los músicos; e. utilización de la música; f. creatividad artística. La metodología está basada en la etnografía, o sea, en el trabajo de campo antropológico, es decir, en la convivencia del investigador con los sujetos de estudio, refiriendo los aspectos que hacen a su propia cultura. En este sentido, las técnicas que constituyen a la etnografía están basadas en la observación, o sea, el examen del tiempo y/o espacio de los sujetos de estudio, y la entrevista, es decir, el conocimiento de los pensamientos sociales y/o culturales de los sujetos de estudio. Esta metodología se ha efectuado entre los miembros de la Congregación Cristiana Vida Nueva, que funciona en la ciudad de La Paz, zona de Villa Fátima, avenida Tejada Sorzano, nº 532. Concretamente, las técnicas etnográficas han sido aplicadas al “ministerio de alabanza y adoración” de esta congregación pentecostalista. Por su parte, las entrevistas personales se han realizado mayoritariamente entre los músicos cristianos del grupo Ciudad de Dios. En conclusión se afirma que la definición ideológica del rock cristiano se efectúa en el acuerdo íntimo o “comunión de santidad” que los creyentes cristianos tienen con Dios; pero, también, en relación con la utilidad práctica que esta clase de música cristiana ofrece para la evangelización y/o adoración pentecostalistas, principalmente

Full textAbstract:
An experimental study has been carried out to investigate the behaviour of rock under multiaxial compression and assess the influence of both the stress conditions and test configuration on the apparent characteristics of this behaviour. Over three hundred specimens of Springwell sandstone, of various forms, have been tested using different loading techniques and most encountered stress fields. Cubes and thick-walled hollow cylinders have been subjected to uniaxial, biaxial, triaxial and polyaxial compression, and solid cylinders have been subjected to standard uniaxial and triaxial compression. Extensive work has initially been put into designing and developing the testing facilities required. A new multiaxial hollow cylinder test apparatus has been devised using a Hoek triaxial cell and specially designed system for the application of internal pressure, major modifications have been made to an existing multiaxial cubical test apparatus, and appropriate testing arrangements and procedures have been developed. Prior to initiating the experimental programme, characterisation tests have been conducted to determine the fundamental properties of the rock, and non-destructive ultrasonic wave velocity tests have been utilised together with statistical methods to examine any inherent variations in the specimens used. A remarkable agreement has emerged between the rock static and dynamic Young's moduli and the results have confirmed that the Springwell sandstone can practically be regarded as linear elastic, homogeneous and isotropic. The concept of the multiple failure state triaxial test has been utilised and extended to conduct multiple failure state polyaxial tests. While the concept remains useful, strain results obtained beyond the first failure state are likely to be inconsistent. Results of cube tests have been found to be highly influenced by the boundary conditions. Although the use of PTFE sheets can reduce the effect of friction between the specimen and the loading platens, it may equally have a weakening effect on the test specimen. The theory of elasticity has been found adequate to calculate the stresses in the hollow cylinders but remains inexact when deviation from linear behaviour occurs prior to failure. When the outer and inner surfaces of the cylinder are not perfectly concentric, the effect on the test results has proved negligible. Hollow cylinders have been found to provide an alternative means for measuring the rock indirect tensile strength. Results of biaxial and polyaxial tests on both cubes and hollow cylinders have confirmed the marked influence of the intermediate principal stress on the apparent strength of rock. Comparison of results from multiaxial tests on cubes, hollow and solid cylinders have shown that the apparent strength, deformability and failure characteristics of the rock are remarkably influenced by the stress conditions imposed as well as the test configuration used. Available failure criteria have advantages and disadvantages, but none of them can explain the diversity of the results obtained. On the whole, the results appear to cast doubt on common conceptions of rock failure and ultimately pose the question of how realistic current testing techniques are in their prediction of the actual behaviour of rock.
