1. Bottom-up and top-down regulation of heterogeneous lake food webs
Sammanfattning : Food webs are networks of organisms linked by trophic interactions that regulate the responses of ecosystems to environmental change. Such regulation is a result of the effects of resources on the abundance of their consumers (i.e. bottom-up effects) and/or the influence of consumers on the abundance of their resources (i. LÄS MER
2. Top-down Methodology to Identify Opportunities for Industrial Symbiosis Partnerships
Sammanfattning : Industries in Europe are responsible for generating approximately 190 Mtons of waste; a figure which is expected to rise, as a significant increase in the consumption of raw materials is predicted to occur in the near future. This may lead to escalating environmental problems, including resource depletion, soil degradation, and climate change. LÄS MER
3. Top-down Fabrication Technologies for High Quality III-V Nanostructures
Sammanfattning : III-V nanostructures have attracted substantial research effort due to their interesting physical properties and their applications in new generation of ultrafast and high efficiency nanoscale electronic and photonic components. The advances in nanofabrication methods including growth/synthesis have opened up new possibilities of realizing one dimensional (1D) nanostructures as building blocks of future nanoscale devices.

4. Top-Down Designers vs Bottom-Up Users : limitations of Heuristic Evaluations on Games
Sammanfattning : Heuristic evaluations are a common way to measure software usability, both during development and to assess existing systems. Generic heuristic tools are aimed at productivity software, but many software domains require domain-specific heuristics. LÄS MER
5. Producing, branding and managing multifaceted tourist destinations: Cartagena, Colombia, as a study case
Sammanfattning : The present dissertation intends to unveil some of the dynamics and processes found in multifaceted destinations. Two broad conceptual areas are considered in order to conceptualize and analyse the issues found in such places: destination making and destination management. LÄS MER
