Abstract:
Thesis advisor: Donnah Canavan<br>Abstract Energy is an emerging concept in social psychology. Baumeister et. al., likening energy to a muscle, have defined exertion of self control as an energy depleting behavior. Energy depletion is measured by reduced performance on a subsequent self-control task. In contrast, Canavan's work on social energy focuses on energy generation and replenishment. Social energy is produced when two or more people are intrinsically interested in the same thing and form a satisfying relationship over this interest. Individuals high in social energy exert more effort,

Abstract:
<p> Traumatic brain injury (TBI) is characterized by a sudden concussive (direct force or shock wave) blow to the head, in which traumatic biomechanical forces are transferred throughout the head and neck. Damage to neural tissue occurs due to rapid acceleration and deceleration forces of the brain, culminating upon impact of the brain with the interior of the skull. At the molecular level, TBI generates a host of physiological responses, which manifest in many different ways. The focus of this thesis will be on the trajectory that progresses through 1) brain acceleration forces, 2) force-indu

Abstract:
Research evidence is suggestive of a strength model of self-control, also known as ego depletion, in social psychological literature. Engaging in an initial task of self-control depletes a limited resource, resulting in less self-control on a subsequent, unrelated task. The strength model of self-control has been applied to many practical, everyday situations, such as eating behaviors among dieters. Newer studies suggest that blood glucose is the resource consumed during acts of self-control. Consuming glucose seems to "replete" individuals who have been depleted, improving performance and sel

Lithium and neodymium are two critical materials in our modern society, many technological solutions depend on them. Lithium is used in batteries, which are used in cars and portable electronics.

Abstract:
Exergy is a thermodynamic quantity capable of measuring the conversion of material and energy flows into comparable terms based on the capacity of such flows to generate mechanical work as a useful effect and identifying and quantifying the thermodynamic inefficiencies of a generic process by means of the exergy destruction term. Because of its properties, an exergy is a convenient tool for the calculation of the global resource consumption of both natural and engineering processes. Therefore, there are different exergy-based approaches. Every exergy-based approach has its advantages and its

Abstract:
The International Energy Agency (IEA) expects total natural gas output in the EU to decrease from 216 billion cubic meters per year (bcm/year) in 2006 to 90 bcm/year in 2030. For the same period, EU demand for natural gas is forecast to increase rapidly. In 2006 demand for natural gas in the EU amounted to 532 bcm/year. By 2030, it is expected to reach 680 bcm/year. As a consequence, the widening gap between EU production and consumption requires a 90% increase of import volumes between 2006 and 2030. The main sources of imported gas for the EU are Russia and Norway. Between them they accounte

It accounts for a third of world primary energy, fuels 95% of global transport systems, sustains a highly mechanised agribusiness and food distribution industry, and provides the feedstock for a staggering array of petrochemical products. Historically, global economic growth has been closely coupled with consumption of energy in general and oil in particular.

The formation of modern society has been dominated by coal and oil, and together these two fossil fuels account for nearly two thirds of all primary energy used by mankind.  This makes future production a key question for future social development and this thesis attempts to answer whether it is possible to rely on an assumption of ever increasing production of coal and oil. Both coal and oil are finite resources, created over long time scales by geological processes. It is thus impossible to extract more fossil fuels than geologically available.

This study investigates the use of discretion by oil and gas companies in reporting financial performance and oil and gas reserve estimates during times of high political scrutiny resulting from increases in energy prices.

This study uses a measure of high profitability (rank order of return on assets relative to industry peers) to identify oil and gas companies more likely to manage earnings during the period from 2002 to 2008.
