Design of an Experimental Rig to Characterize the Gust Response of Small Wind Turbines and Autorotating Seeds
This thesis investigates the rotational behavior of abstracted small-wind-turbine rotors exposed to a sudden increase in oncoming flow velocity, i.e. a gust. These rotors consisted of blades with aspect ratios characteristic of samara seeds, which are known for their ability to maintain …

Live Load Testing and Analysis of the Southbound Span of U.S. Route 15 over Interstate-66
… over Interstate-66. The main performance and behavior characteristics focused on are service strain and deflection, wheel load distribution, dynamic load allowance, and rotational behavior of bridge bearings. Data from this test will be used as a tool in developing and refining a plan for …

Motion of Janus and Patchy Particles Near Various Boundaries
… serve as the means to significantly alter the behavior of such particles. Thus, the dynamics of both passive and chemically active Janus and patchy particles near a wall and different water/oil interfaces has been probed theoretically and experimentally. The Brownian dynamics simulation …

50-kHz ultrasonic vocalizations in hemiparkinsonian rats repeatedly treated with dopaminomimetic drugs as a possible behavioral marker of the affective properties of dopamine-replacing therapy in Parkinson's disease
… of 50-kHz ultrasonic vocalizations (USVs), a behavioral marker of positive affect, in rats bearing a unilateral lesion with 6-hydroxydopamine (6-OHDA) in the medial forebrain bundle. Apomorphine (2 or 4 mg/kg, i.p.), L-3,4-dihydroxyphenilalanine (L-DOPA, 6 or 12 mg/kg, i.p.), or pramipexole (2 …

Kinematic evolution, metamorphism, and exhumation of the Greater Himalayan Series, Sutlej River and Zanskar regions of NW India
… analyses. Finally, focus is given to the rotational behavior of rigid inclusions suspended in a flowing viscous matrix from a theoretical perspective. Predictions of clast rotational behavior have been used to construct several kinematic vorticity estimation techniques that have become …

Preparation and Characterization of Solid Solutions of Ternary and Quaternary Antimony Oxides
… a structural and magnetic phase transition behavior. For the structure, it is designed to study a second order transition of CuSb2O6 at high temperature to find a possible intermediate orthorhombic modification which could be revealed by synchrotron powder diffraction and neutron single …

Coupled orbit-attitude mission design in the circular restricted three-body problem
… of motion and quaternion kinematics describe the rotational behavior of the spacecraft, whereas the translation of the center of mass is modeled in the CR3BP equations. A multiple shooting and continuation procedure are employed to target orbit-attitude periodic solutions in this model. …

Tumor Necrosis Factor Dependent Mechanisms and Neuroprotective Strategies in Models of Parkinson's Disease
… by 50% and attenuated amphetamine-induced rotational behavior, indicative of striatal dopamine preservation in a rodent model of Parkinson's disease. Similar protective effects were observed with in vivo chronic co-infusion of dominant-negative tumor necrosis factor inhibitor with a …

Rotational motion and organization studies of cell membrane proteins
… in the cell membrane bilayer. Both lateral and rotational diffusion of membrane receptors reflects different kinds of intermolecular interactions within the plasma membrane environment. Understanding protein diffusion within the membrane is very important to further understanding biomolecular …

Effects of non-planar distortions in porphyrin compounds on their properties and functionality
… to explain the unusual experimentally observed rotational behavior of aryl substituents on porphyrins. Meso aryl rotational barriers might be expected to be much higher in dodecaaryl porphyrins than in tetraaryl porphyrins due to the great difference in peripheral crowding, and those NMR studies …

Microstructure Dual-Refinement and Mechanical Properties Manipulation of TiBw/TA15(Si) Composites by Thermo-mechanical Processing and Heat Treatment
… and high-temperature tensile mechanical behaviors of the material were discussed. After compositional design through thermodynamic calculation, TiBw/TA15(Si) composites with different Si and Zr contents and a network architecture were prepared by low-energy ball milling and vacuum …

Νευροφαρμακολογία και λειτουργική ανατομία των βασικών γαγγλίων του εγκεφάλου: Πειραματική μελέτη σε επίμυες
… ventral striatum exhibited different patterns of rotational behaviour. These differences were largely attributed to the distinct topographic localisation of the two major striatal efferent systems within the striatum. It is well established that intrastriatal dopaminergic activity is mediated …
