Vessels
My artwork serves as a means of exploration of ideas and of representations of experience. I choose to deal with symbols because, as carriers of meaning in the context of various cultures, symbols afford an exploration of the varied ways in which meaning is made. Use of symbols from diverse …

Leaky Vessels
… cultural dimensions to engage. I propose “leaky vessels” as an analytical tool and a methodology that foregrounds the tension between intentional and unintentional in order to attend to the issues of care, belief, and labor that arise within this dynamic. Chapter 2 develops the concept of “leaky” …

Future characteristics of Offshore Support Vessels
… this thesis focuses on Platform Supply Vessels (PSVs) and the advantages of certain design characteristics are analyzed by modeling representative offshore exploration and production scenarios and selecting support vessels to minimize costs while meeting supply requirements. A review of …

Engineering functional blood vessels in vivo
… the vascular cells could readily form functional vessels in situ. Previous work in the laboratory had successfully demonstrated the formation of functional microvascular network by co-implantation of human umbilical cord vein endothelial cells (HUVECs) and 10 T 1/2 cells, a line of mouse embryonic …

Computational Investigation of Lymphatic Valves and Vessels
… the body via contractions of lymphatic vessels. This flow from vessel contractions is regulated by unidirectional lymphatic valves, which allow lymphatic pumping against adverse pressure gradient. Despite the importance of the lymphatic system, understanding of lymphatic operation, …

Vanishing Act: Lymphatic Vessels and Disappearing Bones
… with GLA or GSD develop ectopic lymphatic vessels in bone and gradually lose bone. Despite growing interest in the development of tissue-specific lymphatics, the cellular origin of bone lymphatic endothelial cells (bLECs) is not known, and the development of bone lymphatics has not been …

Improved operational limits for offshore pipelay vessels
<p>Subsea pipelines are used extensively throughout the world’s oceans to transport oil and gas from offshore facilities to land, often hundreds of miles. These pipelines range in diameter from three to sixty inches and are installed in deeper depths every year, currently as deep as 2,900 meters. …

Characterization of endothelial cells of lymphatic vessels
… form the inner lining of blood and lymphatic vessels. In mice only tumours of the blood vessel endothelium (haemangiomas) have been thus far reported. In the first part of this thesis is described a highly reproducible method for the induction of benign tumours of the lymphatic endothelial …

Salt Vessels: Unearthing the Wonder of Salt
… Based on this history, table-sized salt vessels were created to advance an appreciation of salt as a mineral that not only enhances life but is necessary for man's survival. This thesis examines salt's historical role in terms of trade, war, religion, and culture. Artistic influences that …

Dynamics of premixed flames in closed vessels
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-10-20 without embargo terms

Modelling of Residual Stresses of Blood Vessels
… stress distribution over arterial walls in blood vessels is affected by residual stresses and stresses due to blood pressure. However, residual stresses are still not reliably determined. For this reason, a suitable incorporation of these stresses is required in order to establish the wall stress …

Wedged Vortex Generator Applications for Marine Vessels
This thesis investigates the effectiveness of vortex generators (VGs) in reducing viscous drag in hydrodynamic applications. Initial experimental and computational fluid dynamics analyses identified wedge-shaped VGs as the optimal design for flow manipulation. Comparative testing of three wedge …

Hydrodynamics of unconventional SWATH vessels in waves
… Small Water-plane Area Twin Hull (SWATH) vessels are unique in the sense that viscosity has significant non-linear effects on their hydrodynamic parameters. The parametric optimization of the hull shape of these vessels to reduce the total resistance in waves yields an interesting hull …

Littoral combat vessels analysis and comparison of designs
… U.S. Navy of small, inexpensive, missile bearing vessels is recommended. Four alternative candidate vessels are evaluated using a mathematical simulation. The candidates are a Littoral Combat Ship with a surface warfare module, a National Security Cutter augmented with offensive and defensive …

Composite hydrogel-nanofibre vessels for vascular graft applications
A vascular graft should mimic the structure and properties of the native artery which has a layered structure. The media layer of native arteries contributes the main mechanical support to the vessel and the intima layer, lined with endothelial cells, provides a smooth antithrombogenic surface for …

ENDOTHELIAL- EPITHELIAL INTERACTIONS Blood vessels friends or foes?
… use of mice we have been able to study how blood vessels regulate the growth of the precursors of β cells. We have also been able to show that the formation of a tubular system in the pancreas is important for the regulation of which cell types that are to be formed. Our results can be used to …

Bond strength history in prestressed concrete reactor vessels
… strength history in Prestressed Concrete Reactor Vessels (PCRV) which house the Advanced Gas-cooled Reactors. Three-dimensional non-linear analytical model has been developed in which the effect of bond is included. A finite element computer program is written in which solid, membrane, line and …
