2. 1. Bottom-up and top-down regulation of heterogeneous lake food webs

   Author : Fernando Chaguaceda; Peter Eklöv; Kristin Scharnweber; Lars Tranvik; Blake Matthews; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; food webs; resource coupling; ontogenetic diet shifts; resource specialization; bottom-up; top-down; browning; eutrophication; lake; mesocosms; fatty acids; apparent competition; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

   Abstract : 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.

4. 2. Top-down Methodology to Identify Opportunities for Industrial Symbiosis Partnerships

   Author : Joao Patricio; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular Economy; Top-down methods; Industrial Waste; Recycling; Material Inputs; Industrial Symbiosis;

   Abstract : 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. READ MORE

5. 3. Top-down Fabrication Technologies for High Quality III-V Nanostructures

   Author : Shagufta Naureen; Srinivasan Anand; Clivia M. Sotomayor Torres; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V nanostructures; colloidal lithography; top-down fabrication; dry etching; quantum well; multilayer structures; nanowires; nanopillars; nanodisks; mono-layer etching; surface passivation; photoluminescence; carrier life time; total reflectivity; photonic crystals; nanomesh;

   Abstract : 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.

6. 4. Top-Down Designers vs Bottom-Up Users : limitations of Heuristic Evaluations on Games

   Author : Björn Strååt; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Design; Heuristic evaluation; video games; expert analysis; user comments; Computer and Systems Sciences; data- och systemvetenskap;

   Abstract : 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. READ MORE
