Popular Abstract in English Plants, algae and some bacteria are able to harvest solar energy to run chemical reactions by a complex process known as photosynthesis. Crucial molecules in this process are the so-called light-harvesting antennas. These antennas contain large amounts of pigments, such as chlorophyll, that are used for solar light absorption. Moreover, these pigments are also involved Multichromophoric systems are very important in photosynthesis and any device that uses solar energy for its operation. This is because multichromophoric light-harvesting antennas are responsible for the absorption of light and the efficient transfer of the absorbed energy toward distinct places where it is to be used or stored. Over the last 10 years polarization sensitive single molecule methods

We live in a time of wireless technologies, robotics and small computers with very high computing power. This is mainly due to a large emphasis given towards the study of semiconductor materials which are the building blocks of today's electronic industry. One of the secrets behind creating faster computers is the ability to integrate more and more transistors on a small semiconductor chip. GordonThis thesis studies the role of interaction between charged particles for transport and optical properties in nanostructures. Simulations are provided for a quantitative description of the system dynamics probed by either current spectroscopy or light absorption. In the first part of the thesis (Part I) the basic theories are described and in the second part of the thesis (Part II) the papers lis

During the last decades the forest damage in the Black triangle region (where the borders of the Czech Republic, Germany and Poland meet) has increased rapidly. Many attempts to explain the widely spread damage has been done. To quantify the risk of damage, the expression "critical level" has been introduced. Critical level is the highest concentration of an acidifying compound that the

As the ASIC designs continue to grow in complexity, traditional RTL level of abstraction is becoming a productivity bottleneck. The RTL design process requires extensive time and effort for verification of algorithmic correctness as well as correct timing and interface behavior. Furthermore, a non-trivial change to the algorithm often results in a complete rewrite of the RTL implementation. High L

By use of a batch microcalorimeter of the thermopile type, heat production was measured in isolated populations of human peripheral blood cells exposed to defined immune complexes formed in vitro. It was found that most of the heat production recorded in whole blood after admixture of immune complexes occurs in the granulocytes. Under these conditions small but constantly higher activation values

This thesis analyzes the workings of the natural resource curse in Bolivia through a comparison between two periods with different institutional conditions and under dependency on tin and natural gas respectively. First the conditions for handling the resource curse are analyzed and a hypothesis is presented, suggesting that both periods are likely to have suffered from the natural resource curse

The study investigates employees' perceptions of trust within the Swedish Police and the Swedish Armed Forces. Trust is critical for organisational success, yet there is a lack of research comparing different dimensions of trust within these public sectors. This topic is particularly relevant given the rising threats to Sweden's national security, resulting in military rearmament and incre

The negative effects of transport in terms of pollution, congestion and climate change has urged the need for higher shares of cleaner and more efficient modes of transport, especially in urban settings. While new technologycan solve some of these issues, behaviour changes has also been identified as an important factor to achieve a modal shift from cars to walking, cycling or public transport. Th

In the last years the use of information communication technologies (ICTs) has become a leading driver of OECD national health systems to improve healthcare quality and reduce healthcare costs (Oecd, 2010). In fact, the use of ICTs are a primary lever of OECD countries to enhance the efficiency and the effectiveness of health services delivered to the citizens. This has led the Italian government

Sustainability reporting has become the primary measure of corporate sustainability in the EU, with increasing awareness among companies about the importance of disclosing sustainability matters. Concurrently, the European Union has enacted several pieces of legislation regarding sustainability reporting, notably the Corporate Sustainability Reporting Directive. While blockchain technology initial

Recent suggestions propose that the glacial landscape in southern Sweden is primarily a relict from the Saalian glaciation (>130 ka). The arguments for this standpoint are the assertion that the majority of glaciofluvial deposits in this region are till-covered, and that wind-abraded clasts are observed at the contact between glaciofluvial sediments and till at numerous locations. Furthermore, it

The business world of today is experiencing a phase of change. Customers increasingly demand global relations, static supply chains are replaced by dynamic supply networks, and suppliers are located worldwide. Changes such as these impose new demands on the functionality of enterprise systems. Sync is a company that recognized the changing demands at an early stage. During five years of operations
