Manufacturing of synthetic soda ash.

Madima, Takalani. January 2009 (has links)
<p>The aim of the project was to study the manufacturing of synthetic soda ash (sodium carbonate, Na2CO3) on an industrial scale. Currently all Soda ash that is used in South Africa for manufacturing glass is imported at a high cost, and the company Nampak Wiegand Glass (South Africa) is investigating the possibility to locally manufacture synthetic soda ash. About 75% of soda ash is synthetically produced from either the Leblanc process, Solvay process, Modified Solvay (Dual) process or dry lime process. This study concentrated on the Solvay process on a laboratory scale for eventual input into a larger pilot plant. The produced material was analyzed using analytical techniques such as FTIR (Fourier Transform Infrared spectroscopy), Scanning Electron Microscopy and Energy Dispersive X-ray Spectroscopy, Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma Atomic Emission spectroscopy (ICP-AES). There are certain standard requirements for impurities in the soda ash, and this needed to be measured and determined what changes to the process will bring the impurities to the required minimum standard. Environmental issues around the manufacturing process were also studied. After completing of the laboratory experiments and the extraction of required data from the results, Nampak will use the information to decide on a followup to the building of a small pilot plant to further test and develop the engineering and economical aspects of a full plant. If successful a full scale manufacturing plant can be developed in South Africa for producing soda ash.&nbsp / This study thus will not only help Nampak Wiegand Glass in finalizing the decision to go ahead, but its result will also benefit other companies that use the soda ash in oil refining, water treatment, pulp and paper, chemical industry etc. Some parts of the work done will be proprietary to Nampak and subject to confidentiality agreement.</p>

Generic music style preferences of urban South African adolescents : a follow-up study including additional genres of Hip-Hop, House, Kwaito, Metal and Rhythm&Blues

Matthews, Robert Eric 03 July 2011 (has links)
This exploratory study measured the generic music style preferences of urban South African adolescents using a cross-section of grade nine adolescent learners living in Johannesburg. Johannesburg is the third largest city in Africa and the largest in sub-Saharan Africa. Quantitatively, through a survey, the research determined which music styles were preferred and qualitatively, through interviews, established the extent to which multifarious variables affected preference. LeBlanc’s Model of the Sources of Variation in Music Preference was used as the theoretical framework upon which the study was built. A similar study, completed ten years ago on South African urban adolescents, conducted by Jennifer James, inspired this study and was used as a point of departure for this project. James’s 2000 study was entitled, Generic Style Music Preferences of Urban South African Students. Examples of fifteen generic styles of music, selected from popular, classical and indigenous traditions, were used as music excerpts in the listening test (Music Preference Questionnaire). Through purposive sampling, a total of five-hundred and sixty-eight learners in grade nine participated in the study. The learner sample used was demographically true in its representation of the country’s population. Three broad categories of variables pertaining to preference were delineated and discussed within the study. These encompassed listener, music and environmental variables. Learner variables included: music training, gender (sex), ethnic group (race and language), socio-economic status, and age. Music variables pertaining to preference included: physiological properties of the stimulus [music], complexity of the stimulus [music], and referential meaning of the stimulus [music]. Environmental variables pertaining to preference included media, peer influence, family influence, and the influence of teachers and authority figures. The study revealed that the current generic music style preferences of South African urban adolescents in order of most to least preferred were: Rhythm and Blues, Western Pop, Kwaito, Reggae, House, Hip-Hop, South African Pop, Western Choral, Metal, Rock, Gospel Jazz, Traditional African, Western Classical and Indian Classical. / Dissertation (MMus)--University of Pretoria, 2011. / Music / unrestricted

Indéterminé

LeBlanc Lavigne, Pascale 02 February 2024 (has links)
Dans la mesure où l’écriture n’est pas un médium qui parvient à véritablement alimenter ou à s’inscrire dans mon travail, je crains que ce texte soit extrêmement éloigné de mes créations, « le langage constituant une barrière entre le réel et nous, ne peut être aussi spontané que l’expérience elle-même ». La présente tentative de parler, non pas directement de ma recherche en arts visuels, mais de ce qui l’anime et de son aboutissement, est ainsi paradoxale. L’intuition qui guide mes réalisations, l’art et l’expérience de la création sont « incompatibles avec la certitude » et la structure du langage. Par les arts, je ne tente pas de faire état d’une idée, mais d’un monde sensible, d’expériences subjectives que je chercher à partager. Ainsi, bien que l’on voudrait que ce texte accompagne une exposition, il est davantage le récit sommaire de mon parcours universitaire, accompagné de quelques réflexions qui l’auront ponctué, que la théorisation d’une démarche artistique. D’ailleurs, au moment d’écrire ces lignes, aucun des éléments de mon exposition de fin de maîtrise n’a encore pris forme. Croyant que l’art et la création s’enracinent dans l’écart entre l’idée de départ et le résultat, je me permettrai simplement d’énoncer et de décrire les prémisses d’une installation qui fera office d’exposition de fin de maîtrise.

"Il m'apparut un après-midi d'été ..."

LeBlanc, Évangéline 01 December 2023 (has links)
J'ai choisi la photographie comme principal médium de ma pratique artistique parce que j'aime capter au vol la vie de tous les jours. Avec la photographie, je me sens confrontée à la réalité. Mes clichés reflètent un paysage immobile, recadré, que j'ai tué au passage et figé dans le temps. Ils représentent aussi la mémoire d'un lieu ou d'un objet en soulignant la présence de l'autre. Lorsque je parle de capturer l'image, je cherche à concrétiser le désir de la fixer et de la garder en souvenir. Un souvenir impérissable, immortel ... Mon errance photographique se traduit par de multiples facettes. Depuis plusieurs années, mon appareil photo est le prolongement de mon corps. Il habite mon environnement journalier et amplifie ma vision à la manière d'un troisième œil. J'ai structuré mon processus créatif dans un ordre logique afin de bien expliquer ma recherche visuelle, tout en respectant ma nature intuitive et spontanée. Le fruit de ma démarche prend finalement l'aspect d'un film photographique (multimédia).

Entre chien et loup : travail sur l'image singulière

LeBlanc, Nathalie 23 April 2018 (has links)
Mon travail de création à la maîtrise a principalement été de réaliser des vidéos contemplatives et des collages en modifiant des images. À l’aide de différents logiciels ou techniques de montage, j’ai modifié des photographies, des séquences de films, des images tirées de webcam, des reproductions de même que mes propres captations. Ce texte présente mon travail artistique en venant établir des liens entre mes projets de création, des œuvres et des notions théoriques qui touchent à différentes idées de l’image singulière. Ce texte divisé sous cinq thèmes qui se sont dégagés de mes recherches — dévier, appropriation, montage, singularité et temps — permet de rendre compte de mes réflexions sur mon travail de l’image. Plus précisément, je spécifierai en quoi remanier une image est pour moi la manière de la rendre singulière.

Les relations d'un député québécois avec ses commettants et son milieu : le cas Denise Leblanc-Bantey aux Îles-de-la-Madeleine / Cas Denise Leblanc-Bantey aux Îles-de-la-Madeleine

Ricard, Jean-François 24 April 2018 (has links)
Ce mémoire se veut une étude de cas sur les relations d'un député québécois avec ses commettants et son milieu. Nous nous sommes basé sur l'expérience de Denise LeBlanc-Bantey, députée des Îles-de-la-Madeleine pour le Parti québécois entre 1976 et 1985, pour effectuer notre recherche. Les principaux objectifs de ce mémoire étaient de cerner les véritables problèmes auxquels les députés sont confrontés par leurs contacts directs et indirects avec leurs commettants. Le choix de la circonscription des Îles-de-la-Madeleine et de sa députée de l'époque s'explique par la spécificité de cette région. En effet, nous avons tenté d'établir un lien entre les caractéristiques propres aux îles et les problèmes rapportés à la députée. Dans le même sens, nous avons suivi les démarches entreprises par LeBlanc-Bantey, auprès des ministres et des autorités municipales de son comté, pour régler les problèmes de ses commettants. Finalement, nous avons porté une attention particulière à son travail d'adjointe parlementaire aux pêcheries puisqu'il nous apparaissait plutôt rare pour un député d'être en charge du plus important secteur économique de sa circonscription. / Québec Université Laval, Bibliothèque 2013
