The purpose of this paper is to provide insight into how companies work during packaging development to reduce negative environmental impact along supply chains, and to compare their practical approaches with the theoretical concepts presented in the literature. The research approach is explorative and based on nine cases in the food and manufacturing industries in Sweden. Data were collected from
Pupils have gotten school meals in Sweden since the late 1800´s. The school meal has of course changed over the years. In the beginning the pupils only got porridge and milk. Since then they serve both meat-, fish- and chicken dishes. In recent years, many schools around the country are more concerned about the environment and therefore started to serve more plant-based diets and less red meat. Re
This thesis focuses mainly on the co-integration of vertical nanowiren-type InAs and p-type GaSb MOSFETs on Si (Paper I & II), whereMOVPE grown vertical InAs-GaSb heterostructure nanowires areused for realizing monolithically integrated and co-processed all-III-V CMOS.Utilizing a bottom-up approach based on MOVPE grown nanowires enablesdesign flexibilities, such as in-situ doping and heterostr
Popular Abstract in Swedish Djurs förmåga att hitta då de förflyttar sig långa sträckor mellan fortplantningsområden och övervintringsområden har fascinerat människor i hundratals år. Det finns flera olika teorier kring hur djur navigerar, till exempel med hjälp av dofter, landmärken, solen, polariserat ljus, stjärnorna eller jordens magnetfält. Att djur skulle kunna använda sig av just jordens maMigration research is a large and diverse field and in my thesis I have focused on the impact of geomagnetic cues on animal orientation, navigation and migratory fuelling. Several animal species from widely different taxa possess the ability to sense and make use of geomagnetic information during migratory or homing events. I used a map showing isolines for magnetic total field intensity and incl
Septic tanks with subsequent soil treatment systems (STS) are a common treatment technique for domestic wastewater in rural areas. Phosphorus (P) leakage from such systems may pose a risk to water quality (especially if they are located relatively close to surface waters). In this study, six STS in Sweden (11-28 years old) were examined. Samples taken from the unsaturated subsoil beneath the distr
We have studied the dynamics of water molecules in six crystal structures of four human cytochromes P450, 2A6, 2C8, 2C9, and 3A4, with molecular dynamics simulations. In the crystal structures, only a few water molecules are seen and the reported sizes of the active-site cavity vary a lot. In the simulations, the cavities are completely filled with water molecules, although with similar to 20% low
The business model concept is becoming increasingly popular within e-businesses and e-business research. However, the concept is often used relatively independently from theory, meaning model components and their interrelations are relatively obscure. This paper analysis three e-business models taxonomies based on a generic business model, which include customers and competitors, the offering, act
Proteins are large, complex molecules that play many critical roles in the body and are required for the structure, function, and regulation of the body’s tissues and organs. In very simple terms, a protein can be defined as a linear chain of subunits called amino acid residues. The individual amino acid residues are sequentially bonded together by peptide bonds. There are 20 standard amino acids This work is primarily about the development, validation and application of computer simulation models for intrinsically disordered proteins, both in solution and in the presence of uniformly charged, ideal surfaces. The models in question are either coarse-grained or atomistic in nature, and their applications are dependent on the specific purpose of each study. Both, Metropolis Monte Carlo and m
Occupancy of cold habitats by evergreen species requires structural modification of photosynthetic organs for stress resistance and longevity. Such modifications have been described at interspecific level, while intraspecific variation has been underexplored. To identify structural and anatomical traits that may be adaptive in cold environments, we studied intraspecific variability of needles of S
Coastal systems can act as filters for anthropogenic nutrient input into marine environments. Here, we assess the processes controlling the removal of phosphorus (P) and nitrogen (N) for four sites in the eutrophic Stockholm archipelago. Bottom water concentrations of oxygen (O2) and P are inversely correlated. This is attributed to the seasonal release of P from iron-oxide-bound (Fe-oxidebound) P
Advances in mobile and wireless technology have expanded the scope of electrodermal research. Since traditional electrodermal measurement sites are not always suitable for laboratory research and are rarely appropriate for ambulatory measurements, there is a need to explore and contrast alternate measurement locations. We evaluated bilateral electrodermal activity (EDA) from five measurement sites
Urbanisation leads to increased thermal stress in hot-humid climates due to increased surface and air temperatures and reduced wind speed. We examined the influence of urban morphology and sea breeze on the microclimate of Colombo, Sri Lanka. Air and surface temperatures, humidity and wind speed were measured at 1 rural and 5 urban sites during the warmest season. The urban sites differed in their
The overall aim of this thesis is to develop knowledge of teaching and learning sustainable development in global–local contexts. The research field is global learning for sustainable development (GLSD). Phenomenographic approach and contextual analysis were used as methods of analysis, and data was collected by Semi-structured interviews at secondary and upper secondary schools in Sweden.In Study
Popular Abstract in English Among the forms of life found in extreme environments (e.g. high temperatures ‘thermo’ and oxygen deficient ‘anaerobe’), the thermoanaerobic bacteria emerge as a highly evolved and interesting subject of study. Bacteria living as microbial mats in decaying plant material possess a great potential not only to degrade complex biomass but also to produce special chemicals.A novel ethanol-producing thermoanaerobe Caloramator boliviensis 45BT (=DSM 22065T, =CCUG 57396T) was isolated from a hot spring of the Bolivian highlands. C. boliviensis possesses the ability to utilize a wide range of substrates and can efficiently convert hexoses and pentoses into ethanol with concomitant production of acetate, carbon dioxide and hydrogen as by-products of fermentation. However
