2. 1. Molecular Dynamic Simulations of Biological Membranes

   Author : Qaiser Waheed; Olof Edholm; Friederike Schmid; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; phospholipids; area compressibility; undulations; quantum corrections; cholesterol; phase transition; segregation;

   Abstract : Biological membranes mainly constituent lipid molecules along with some proteins and steroles. The properties of the pure lipid bilayers as well as in the presence of other constituents (in case of two or three component systems) are very important to be studied carefully to model these systems and compare them with the realistic systems.

4. 2. Sensory Quality and Consumer Perception of Wheat Bread : Towards Sustainable Production and Consumption. Effects of Farming System, Year, Technology, Information and Values

   Author : Iwona Kihlberg; Einar Risvik; Lisbeth Johansson; Stefan Sahlstrøm; Uppsala universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Domestic sciences; Product quality; Production quality; Sustainability; Organic farming; Wheat; Organic Food; Bread; Milling; Breadmaking; Sensory analysis; Consumers; Information; Values; Food acceptance; Hushållsvetenskap; Domestic science and nutrition; Hushålls- och kostvetenskap;

   Abstract : In order to study the effect of production systems aimed at sustainability on product quality and of sensory and non-sensory factors on product acceptance – the effect of farming system, year, milling and baking techniques on the sensory qualities of wheat bread as a model product was investigated using a descriptive test, and the effect of information and values on liking of bread using consumer tests.Whole wheat and white breads were baked with wheat grown in six lots in established conventional and organic farming systems in field trails, in two subsequent years for the white bread.

5. 3. Testing and modelling of silty and sulphide-rich soils

   Author : Yao Yu; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

   Abstract : Silt and sulphide soil are two types of soil which are dominating in northern Sweden, especially in the coast area of the Baltic sea. The stress-strain and strength characteristics of these two soils have so far not been as much explored as those for e.g. Scandinavian clays. READ MORE

6. 4. The influence of particle properties on cake filtration: Surface structure and surface charge

   Author : Jonas Wetterling; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface structure; electrostatic particle interactions; cake filtration; solid-liquid separation; compressible filter cake; local filtration properties;

   Abstract : Solid-liquid separation is often a key process step when biomass is used as a raw material, and an energy efficient way of achieving solid-liquid separation is through cake filtration. However, many biomaterials present challenges when they are filtrated due to the formation of compressible filter cakes. READ MORE

7. 5. Estimation of the Elastic Moduli of Porous Materials using Analytical Methods, Numerical Methods, and Image Analysis

   Author : Thushan Chandrasiri Ekneligoda; Robert W. Zimmerman; Igor Tsukrov; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Abstract : The effective bulk modulus and effective shear modulus of porous materials having various types of pore shapes are investigated, using both analytical and numerical methods. These solutions, and the scaling laws that are derived with the aid of these solutions, are then used to make predictions of the effective elastic moduli of some sandstones and ceramics, based on two-dimensional images of the pore space.
