Selective hydrogenation of lignin-derived model compounds to produce nylon 6 precursorsZhou, Xiaojuan 12 January 2015 (has links)
This study investigated the conversion of monomeric lignin fragments into cyclohexanols for use as a source of lignin-derived monomers for renewable Nylon 6 production. Lignin-derived
monomeric phenolic species was transformed to their cyclohexanol analogs via selective catalytic hydrogenation. A fixed-bed flow reactor was used to evaluate the selective hydrogenation of individual model phenolic species (guaiacol, 4-methylguaiacol or diphenyl ether). The catalyst composition studied was Ni/SiO₂, which was previously shown to form cyclohexanol as an intermediate from phenol. A primary focus was on tuning the reaction conditions to form desired products, while avoiding the formation of bicyclic species which can be precursors
to catalyst deactivation, or fully hydrogenated products of lower value. Reaction pathways of guaiacol, 4-methylguaiacol and diphenyl ether were studied. Major products obtained from guaiacol, 4-methylguaiacol and diphenyl ether reactions were 2-methoxycyclohexanone, 4-methylcyclohexanol and cyclohexanol, respectively. Spent catalyst was analyzed for extent of deactivation.

Range and Straggling Measurements of U-235 Fission FragmentsHallam, John William 10 1900 (has links)
The ranges and stragglings of fission fragments from the thermal neutron fission of U-235 have been measured. Particular attention was given to the preparation of very thin uranium sources, the design of a well collimated recoil system and the preparation of the fragment catcher. The ranges and range distributions in aluminum of fission products of mass numbers 95, 140, 141 and 147 have been obtained. The range values obtained agree with previous determinations within the experimental error. The refined techniques developed in this work have enabled differential range distributions to be obtained which are more precise than any previous determinations. / Thesis / Master of Science (MSc)

Cumulative Yields of the Heavy Fragments in U235 Thermal Neutron FissionFarrar, Harry 05 1900 (has links)
Isotopic abundances of the elements barium, cerium, neodymium, samarium and europium formed in the thermal neutron fission of have been studied with a mass spectrometer. Suitable analyses of very young and old fission products have made possible the normalization of the isotopic abundances of each of these elements through isobaric nuclides. In this manner the relative cumulative fission yield of every fission chain from mass 137 to 154 has been obtained. These yields, together with previously reported relative yields of masses 131 to 137 when normalized to total 100%, give the absolute cumulative yield of all the significant heavy fragment chains. The origin of the fine structure found in this mass yield distribution is discussed. It has been found that all fine structure can be explained in terms of a smooth primary mass-yield curve and a simple neutron distribution both of which are compared with experimental data from other laboratories. / Thesis / Doctor of Philosophy (PhD)

Ambiguous FormLi, Qian 02 August 2018 (has links)
This thesis is an exploration of the ambiguous form. "Ambiguous" means having multiple interpretations. Usually, a figurative presentation will direct people to a particular thing. On the contrary, if familiarity is provided as the only way, people can find a deceptive scenario, and associate it with the corresponding space in his or her memory. This happens because the images stored in our minds are not very refined, especially the ones we see but do not remember deliberately. So we can say that the ambiguous form triggers our association and thinking. It could give us more affordance about architectural space.
In addition, collage, an art of transforming fragments into a whole, is an essential approach for my thesis. The process involves disintegrating something first, analyzing it, then synthesizing the parts together. It is beautiful / Master of Architecture

Of Light and ShadowSutton, Leah M. 01 May 2024 (has links) (PDF)
The work exhibited in Of Light and Shadow is fragmented. The fragments of the work will display an understanding of materiality, immateriality, fragility, temporality, scale, and preservation while seeking to fragment photography as a traditional medium. This work has become less about the image and more about the art object itself and how it exists in the space. I am interested in the connections between art and science where a museum, herbarium, or glasshouse acts as a juxtaposition between art and science. In Of Light and Shadow, the chosen materials question their own materiality. I am interested in the ephemerality of objects and the fragility of their existence. I use light and shadow as a dichotomy that connects the natural and artificial. With this duality and materials manufactured and handmade, I create environments that beckon the viewer to consider other dichotomies such as light and shadow, inside and outside, past and present, art and science, and private and public. They are the in between. Miniaturized fragments contrast larger than life fragments that challenge the viewers’ senses, perception of reality, and scale. This work seeks to fragment photography as a material and immaterial mode of traditional storytelling where it constantly battles the question of “will it disappear” and “if so, when?”

L'espansione di Roma in Oriente : problemi e interpretazioni : commento storico a Diodoro Siculo, XXXI 1-17b Walton / L'expansion de Rome en Orient : enjeux et interprétations : commentaire historique à Diodore de Sicile, XXXI 1-17b Walton / The Roman Expansion in the East : problems and interpretations : a Historical Commentary on Diodorus Siculus, XXXI 1-17b WaltonGandini, Alberto 05 June 2013 (has links)
Ce travail consiste en un commentaire ad locum, à caractère à la fois historique et historiographique, de la première moitié du livre XXXI de la Bibliothèque Historique de Diodore de Sicile, parvenu jusqu’à nous de façon fragmentaire. L’analyse recouvre 34 fragments, correspondant aux chapitres 1-17b de l’édition Loeb de F.R. Walton et issus du récit annalistique de la première olympiade successive à la bataille de Pydna (168/7-165/4 av. J.-C. = Ol. 153). Le choix du sujet se dessine dans le cadre d’un renouvellement général d’intérêt pour les deux dernières décades fragmentaires de l’œuvre diodoréenne, et pour les livres proprement ‘romains’ en particulier (XXIII-XL). Leur étude semble aujourd’hui centrale pour une meilleure appréciation de la personnalité de l’historien d’Agyrion, du fait de la proximité de l’époque de l’auteur aux événements relatés et de l’importance réservée aux deux cents dernières années d’histoire romaine dans l’économie globale de l’œuvre. La double perspective adoptée vise aussi bien à centrer la question de l’interprétation que l’historien sikéliote donne aux faits narrés qu’à envisager de manière novatrice les enjeux caractérisant la phase historique considérée, à la lumière des apports et des sollicitations de la recherche scientifique la plus récente. A côté de l’intérêt porté à l’écriture de Diodore – ici considérée en particulier du point de vue de son rapport avec la tradition polybienne –, une place privilégiée est ainsi accordée à la réflexion sur les causes et les procédés de l’expansion romaine en Orient, à un moment clé pour la redéfinition des équilibres de pouvoir entre l’Urbs et le monde gréco-hellénistique. / This work consists in an ad locum commentary, both historical and historiographical, on the first half part of the XXXI book of Diodorus Siculus’ Historical Library, that has reached us in fragments. This analysis is about the 34 fragments corresponding to the chapters 1-17b of F.R. Walton’s Loeb edition and to the remaining annalistic narration of the first Olympiad following the battle of Pydna (168/7-165/4BC = Ol. 153). The choice of the subject fits within a new general interest for the two last fragmentary decades of the Historical Library, and particularly for the so called ‘Roman’ books (XXIII-XL). A study of this section of Diodorus’ Bibliotheke seems nowadays essential for a better appraisal of the personality of the historian of Agyrion: this is because of the proximity of the author’s time to the events related and because of the great importance of the two last centuries of Roman history into the global economy of his work. The double perspective adopted aims to point out the historian’s interpretation of the facts narrated, but also to reconsider in an innovative way the problems characterizing the period analyzed, specially under the new light offered by the most recent contributions of the scientific research. Therefore, a privileged place is granted to the reflection on the causes and the procedures of the Roman expansion in the East, in a key-moment for the redefinition of the balance of power between the Urbs and the Greco-Hellenistic world, together with a particular attention to Diodorus’ writing, here considered in its relation with the Polybian tradition.
