FORAMINIFERA FAUNA RECOVERED FROM ANDRILL’S (ANtarctica geological DRILLing program) SOUTHERN MCMURDO SOUND (SMS) PROJECT

Patterson, Molly O’Rourke 01 December 2010 (has links)
During the Austral Spring of 2007-2008 the ANtarctic geological DRILLing program (ANDRILL) recovered a 1,138 meter long sediment core AND-2A from the western side of the Victoria Land Basin for the Southern McMurdo Sound Project. The main goal of the project is to help establish a Neogene (~24 to 1.6 Mya) ice volume and climate record of Antarctica. This study focuses on the foraminifera record of AND-2A for paleoenvironmental and biostratigraphic purposes.AND-2A is unique in that it contains a Middle Miocene record (~17 to ~11 Mya) that includes the Middle Miocene transition of warm climatic conditions favoring polythermal ice sheets to major cooling into polar conditions resulting in the quasi-permanent formation of the East Antarctic Ice Sheet. This Middle Miocene transition has not been previously recovered from the Antarctic continental margin.The foraminifer record is not abundant; however, three assemblage zones are identified throughout AND-2A. Calcareous benthic taxa dominate every assemblage, as well as displaying similarities between modern shallow shelf assemblages around Antarctica and assemblages from previous drilling projects in the Ross Sea sector. The foraminifera record displays a dynamic environmental record and is supported by both the sedimentologic and other paleontologic findings.

Friction hydro pillar riveting process of Ti-6AI-4V titanium sheet

Tsikayi, Davies Shamiso January 2015 (has links)
Mechanical fasteners are used extensively in the joining of two or more metal plates or sheets. Riveted joints have been the joints of choice mainly for the Aerospace Industry. However for this research, Friction Hydro Pillar Processing has been used to develop and characterise a new riveting technique termed Friction Hydro Pillar Riveting (FHPR). Two overlapping 3.17 mm Ti-6Al-4V sheets were joined together using Ø6 mm rivet which was friction processed. This research has focussed on the initial development of Friction Hydro Pillar Riveting thereby establishing a basic understanding of the influences of main process parameters, rotational speed and axial force - and also joint configurations. The results showed that with a decrease in the bottom hole chamfer angle, there was resulting overall increase in the rivet joint pull off strength. From the best performing joint configuration in pull off tests, shear tests were conducted whilst a blind hole FHPR joint was also done and tested in pull off and shear strength. The shear test fracture surfaces exhibited ductile failure. The microstructure of the joints was thus evaluated. From parent material, heat affected zone and to weld zone there was a variation in the microstructure analysed. The hardness profiles showed increased hardness in the weld zone which partly explained the shear results. The hardness increase was mainly due to grain refinement in the weld zone by the Friction Hydro Pillar Riveting process.

Enzymatically degradable versatile hydrogel platform for cell sheet engineering

Kim, Joshua Jaeyun 28 October 2015 (has links)
The structural organization of cells and their associated extracellular matrix (ECM) is critical to overall tissue function. Recapitulating the complex, highly organized structure of a target tissue is a key to achieve the unique functional characteristics of native tissue. However, achieving this goal requires a system in which substrate physicochemical properties such as modulus, topology and surface chemistry can be modulated. Here, we developed a cell sheet-based harvest & transfer system that can rapidly produce patterned 2D cell sheets in any physiologically relevant size and shape for various cell types. We further show that these cell sheets can be stacked one on top of the other with high cell viability while preserving the patterns, and that they remain sufficiently intact in vivo to allow neovascularization. We can thus use this system to mimic both the 2D and 3D structure of native tissue structure. A further advantage of our system is its substrate modulus tuning capability, which allows us to provide an optimal biomechanical environment for the differentiation and phenotypic stabilization of specific cell types. Because hydrogels theoretically have no limit in 2D shape and size, this system is scalable for producing quality controlled multiple cell sheets in a short period of time. Our model should also aid in understanding the mechanisms that underlie cell-cell and cell-ECM communication in 3D environments, which will be imperative to improving engineered tissue design. We thus ultimately envision that our system could allow the rapid fabrication of functionalized three dimensional thick tissues from multiple stacks of cell sheets derived from autologous cells, which would be an important step forward in both tissue modeling and regenerative medicine in general. Finally, this system can also potentially serve as a powerful model to study in vivo tissue formation and growth as well as cancer cell behavior.
