2. 1. On the processing and properties of cellulose-containing polymeric materials

   Author : Ruth Arino Marine; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dispersion; extrusion; injection moulding; ionic liquids; compounding; ethylene-acrylic acid copolymer; gels; cellulose fibres; rheological properties;

   Abstract : Cellulose fibres have properties such as renewability, biodegradability, very good availability and low cost that make them very attractive as a reinforcement for thermoplastic polymers. Other more specific favourable properties are low density, high specific stiffness, low abrasive nature and their potential for modification. READ MORE

4. 2. Searching for sustainable aquaculture governance : A focus on ambitions and experience

   Author : Ola Luthman; Rickard Lalander; Fred Saunders; Max Troell; Megan Bailey; Södertörns högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aquaculture; policy; environmental governance; Social-Ecological Systems; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

   Abstract : Aquaculture is one of the most diverse food-producing industries and is suggested as a key solution to a growing global food demand. It has been argued that aquaculture has the potential to expand sustainably in most parts of the world, especially in the EU where consumption far out weighs production. READ MORE

5. 3. Molecular ecology of marine mammals

   Author : Morten Tange Olsen; Per Palsbøll; Martine Bérubé; William “Bill” Amos; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marine mammals; molecular ecology; life history; environmental change; phenotypic plasticity; SNPs; telomeres; molekylärgenetik; Molecular Genetics;

   Abstract : Marine mammals comprise a paraphyletic group of species whose current abundance and distribution has been greatly shaped by past environmental changes and anthropogenic impacts. This thesis describes molecular ecological approaches to answer questions regarding habitat requirements, genetic differentiation, and life-history trade-offs in three species of marine mammals.

6. 4. Simulation model of a ship’s energy performance and transportation costs

   Author : Fabian Tillig; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speed optimization; energy efficiency; wind-assisted propulsion.; performance prediction; energy systems model; ship design;

   Abstract : Society faces a major challenge to reduce greenhouse gas emissions to limit the effects and propagation of climate change. As the main contributor to global trade, the shipping industry adds significantly to global greenhouse gas emissions and must actively work towards reducing, or eliminating, emissions in a short period.

7. 5. Medium Voltage Generation System with Five-level NPC Converters for Kite Tidal Power

   Author : Georgios Mademlis; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Voltage balancing; Maximum Power Point Tracking MPPT ; Medium Voltage Converters; Multilevel Space-Vector-Modulation; Neutral point clamped converter NPC ; Subsea kite; Tidal power;

   Abstract : Offshore power generation has emerged as a prominent source of energy and the installed capacity of new plants has been steadily increasing in recent years. Tidal power specifically is a promising renewable energy source which has not been highly exploited yet, despite its distinctive advantages of being predictable and independent of weather conditions.
