Os sinais clínicos com origem abdominal em cães e gatos são dos estímulos iatrotrópicos verificados de forma mais frequente na clínica de cães e gatos, sendo a imagiologia um importante contributo na avaliação e na determinação do sistema originário do quadro clínico. Este estud…
Computerized tomography (CT) has long been used successfully in different areas of science and engineering. X-ray tomography and MRI in diagnostic medicine, and geographical imaging, usually used for characterizing the subsurface of earth, are well-known examples. For experiment…
Current methods for assessing the health of insects and their colonies are carried out by researchers making dissections on individual insects (which inevitably kills them) or making visual inspections of colonies and then documenting their observations. For colonies, researcher…
The majority of navigation satellite receivers operate on a single frequency and experience an error due to the ionospheric delay. They compensate for the ionospheric delay using an ionospheric model which typically only corrects for 50% of the delay. An alternative approach is …
In this thesis the design and build of a high-speed, video-rate optical coherence tomography (OCT) imaging system is described. The system was designed for the purpose of imaging human skin in vivo, particularly that of patients suffering from conditions such as systemic scleros…
We present ambient noise tomography results of Rayleigh wave group and phase velocities obtained from empirical Green's functions produced by cross-correlating long ambient noise sequences between available station pairs across Europe. Cross-correlations are stacked over the ent…
Objectives : Persons with traumatic spinal cord injury (SCI) have severe bone loss below the level of lesion with the distal femur (DF) and proximal tibia (PT) being the skeletal regions appreciated to have the highest risk of fracture. While a reference areal bone mineral densi…
One of the most important mechanisms of foamy oil is the solvents’ non-equilibrium dissolution and exsolution behavior. Therefore, the real-time capturing of these dynamic properties is crucial in analyzing how foamy oil evolves under non-equilibrium state. In this research, var…
The southwest Pacific is a tectonically complicated region consisting of two large igneous provinces (LIPs) on the ocean floor formed approximately 120 Ma. The formation of these two plateaus, the Ontong Java Plateau (OJP) and Manihiki Plateau (MP), along with one further south,…
Previous investigations have proposed multiple origin models to explain the formation of major tectonic structures, such as the Gamburtsev Subglacial Mountains (GSMs), the Wilkes Subglacial Basin (WSB), the Aurora Subglacial Basin (ASB), and the Transantarctic Mountains (TAMs) i…
