EXC-5 Controls Intracellular Trafficking in Order to Maintain the Apical Structure of the C. elegans Excretory Canal
… where the sorting of material to the apical surface is only required at certain points along the canal where it is undergoing significant restructuring because of growth or physical damage. When exc-5 is mutant, materials are not efficiently sorted to the apical surface where they are needed …

The mechanics of mechanotransduction : analyses of cell perturbation
… supported a non-uniform force transmission to basal surface focal adhesion sites. Proteins in identified zones of high stresses in the cell are candidate mechanosensors and their molecular response to force was hence investigated, A generic model of protein extension under external forcing was …

Force-induced calcium concentration change and focal adhesion translocation : effects of force amplitude and frequency
… cell membrane transmit non-uniformly to the basal cell surface and that focal adhesion sites may function as individual mechanosensors responding to local levels of force. Results from a while applying nN-level magnetic trap shear forces to the cell apex via integrin-linked magnetic beads. …

MPM Modeling of the Impact of Compound Landslides on a Rigid Wall
… This thesis studies the effect of different basal sliding characteristics of biplanar compound landslides on the post-failure mechanics and the interaction with rigid structures. The Material Point Method (MPM), an advanced numerical tool capable of simulating large deformations, captures the …

Basal constriction : shaping the vertebrate brain
… polarized sheets of cells with an apical surface facing a lumen and basal surface resting on the underlying extracellular matrix. Cells within a sheet are joined by junctions, and changes in cell shape and size drive epithelial bending and folding during morphogenesis. These shape changes …

Determination of Surface Free Energies and Aspect Ratio of Talc
… angle measurements were conducted to assess the surface chemistry of the mineral talc. The contact angles were performed on both flat and powdered samples and the results were used to determine the surface free energy components and parameters (SFEC) using the acid-base theory for solids, …

Surface Free Energy Characterization of Powders
… angle measurements were conducted to study the surface chemistry of powdered minerals. The contact angle measurements were conducted on both flat and powdered talc samples, and the results were used to determine the surface free energy components using Van Oss-Chaudhury-Good (OCG) equation. It …

High Resolution Facies & Architectural Analysis of a Tributive, Basal Terrace of a Ferron Compound Incised Valley
… and description of the major valley surfaces and associated deposits of a compound incised valley that forms much of the base of Sequence 1 throughout the area. The oldest valley terrace, of what are thought to be three constituent valleys formed during a stepped relative fall of sea …

Interplay between interkinetic nuclear migration and cell fate determination in the developing zebrafish retina
… movement of nuclei between the apical and basal surfaces of the neuroepithelium during the process of interkinetic nuclear migration (IKNM). The precise role of IKNM in creating the organized diversity of neuronal tissues is the topic of continued and vigorous investigation. Therefore, we …

Exploring Polarized Membrane Protein Distribution in Drosophila Follicle Cells using Proximity Labelling
The establishment and maintenance of apical–basal polarity in epithelial cells depend on the faithful sorting and delivery of proteins to distinct plasma membrane domains. Using the Drosophila follicular epithelium as my model, this thesis applies peroxidase-mediated proximity labelling and mass …

Strategies to Target the Bone Morphogenetic Protein Signalling Pathway in Lung Disease
… where the nutrition is provided through the basal surface of the cells and the dorsal surfaces of the cells are exposed to air. Murine model of OVA induced asthma in vivo was also stimulated with exogenous BMP4 and the effects monitored. Human primary cells and primate primary cell isolates …

Structural and Petrologic Evolution of Acadian Dome Structures in Southern Vermont
… Hill Terrane; an Ordovician arc sequence. The basal surface of this allochthonous mass projects above the present land surface within this area. Accretion of lower-plate rocks (of this study) into the thrust complex and continued west-directed thrusting of the accreted package over a …
