Abstract:

The thesis presents background on solar thermal energy and addresses the structural challenges associated with the deployment of concentrating solar power fields in urban areas. Two potential structural systems and urban locales of deployment are proposed and investigated to determine whether they have the potential to be a cost-effective renewable energy solution for urban areas. The structural issues explored in the thesis include flutter, the wind loading of open frame structures, performance-based design, and the design of flexibly mounted equipment on a building.

Abstract:

In Swedish dialects we find the terms ris,skäver and skärva referring to illnesses in children. The words are also parts of various compounds which refer to variants of the illnesses. The terms are linguistic expressions denoting two folk categories of illnesses, RIS and SKÄVER/SKÄRVA. These categories are investigated from a cognitive semantic perspective. The cognitive perspective argues that we organize our understanding of reality by using Idealized Cognitive Models (ICM) based on our physical, mental and emotional experiences of the world.

Abstract:

Nucleoside transporters catalyse the passage across the cell membrane both of natural nucleosides, which play key roles in cell physiology, and of nucleoside analogues, which are widely used in chemotherapy. In humans two structurally unrelated families of nucleoside transporters have been identified, the equilibrative and concentrative nucleoside transporters (hENTs and hCNTs, respectively). A bacterial homologue of the hCNTs, the Escherichia coli transporter NupC, has been used as a model system for studies of the structure and function of the CNT family. It has an unusual topology with both

As a post-Soviet economy, Ukraine has inherited substantial production assets and qualified personnel. However, the economy was dominated by large-scale enterprises designed for much bigger markets.

There was a clear need in restructuring of the entire economy. Restructuring included splitting firms into smaller parts and privatization.

Abstract:

Structures made of chromated copper arsenic (CCA) have been shown to leach arsenic into the surrounding soil. Soil cores were taken adjacent to six CCA decks at 0, 15, 60 and 300 cm from the deck at depths of 0–10, 10–20, and 20–30 cm, and were analyzed for soil arsenic concentrations. Median soil arsenic concentrations ranged from 1.8 μg/g at a depth of 10–20 cm and a distance of 300 cm to 34.5 μg/g at a depth of 0–10 cm and a distance of 30 cm. Soil arsenic concentrations taken at depths of 0–10 and 10–20 cm decreased as distance from the deck increased. Soil arsenic concentrations close to

Abstract:

Critical zone science seeks to develop mechanistic theories that describe critical zone structure, function, and long-term evolution. One postulate is that hydrogeochemical controls on critical zone evolution can be inferred from solute discharges measured down-gradient of reactive flow paths. These flow paths have variable lengths, interfacial compositions, and residence times, and their mixing is reflected in concentration-discharge (C-Q) relations. Motivation for this special section originates from a U.S. Critical Zone Observatories workshop that was held at the University of New Hampshire

Concentration gradients are expected to improve device performance by optimizing the charge transfer, transport and collection processes.

Abstract:

Les travaux presentes dans cette these ont trait aux etudes parametriques d'une structure innovante de machine synchrone a aimants alternes, concentration de flux et petits plots magnetiques excites par bobinages globalises. Ils entrent dans le cadre des recherches sur les nouvelles structures de machines synchrones pour des applications specifiques de forts couples a basse vitesse. Ces machines se caracterisent d'une part par la dissociation geometrique d'echelles entre l'echelle de bobinage et celle de denture, d'autre part par l'accroissement de performances massiques et/ou volumiques resul

Abstract:

This dissertation is focused on understanding heterogeneous bimetallic catalysts using model catalyst systems, such as Pd-Au/Mo(110), Pd/Au(111) and Pd/Au(100). Monometallic and bimetallic model catalysts, composed of Pd and Au, were prepared by physical vapor deposition (PVD) onto well-characterized metal substrates. Subsequent characterization was performed using an arsenal of modern surface science tools: low energy ion scattering spectroscopy (LEISS), infrared absorption spectroscopy (IRAS), temperature programmed desorption (TPD), and x-ray photoelectron spectroscopy (XPS). Electronic, mo

Dissertação de mestrado em Economia (Economia Industrial), apresentada à Faculdade de Economia da Universidade de Coimbra, sob a orientação de Adelino Manuel Guimarães Fortunato e Ernesto Jorge Fernandes Costa.<br>The possibility that the existence of New-Issues Markets (NIM) could promote, through a behavioural response of potential entrants, a greater market concentration on economic sectors is the object of the present work. I analyse in what conditions do entrepreneurs choose to abandon their plans of entering some industry in order to invest in securities of companies in that same industr
