Technical solutions for a number of Swedish industrial installations for dewatering and drying of bark are compiled and discussed. Further, lab-scale experiments with a heated bark pressing process have been performed to investigate to what extent parameters such as temperature and pressure will influence the dewatering process. Pressing with a heated press at 150 °C was shown to increase the dewa
Ionic microgels are intriguing soft and deformable colloids with an effective pair potential that crosses over from Yukawa-like at large distances to a much softer repulsive interaction at short distances. Here we report the effect of adding an anisotropic dipolar contribution to colloids with such "ultra-soft" interactions. We use an alternating electric field to induce a tunable dipolar contribu
A linearly polarized photon beam has been produced at MAX-lab using the coherent bremsstrahlung of electrons with an energy of 192.6 MeV in a 0.1 mm thick diamond crystal. The intensity and shape of the coherent maxima and their dependence on the crystal orientation are similar to the features observed at higher electron energies (similar to 1 GeV) and are well described by coherent bremsstrahlung
Popular Abstract in Swedish Mikroorganismer (bakterier, virus och protozoer) finns överallt I vår omgivning. Vi människor har tio gånger fler bakterier på och i oss än vi har mänskliga celler. De flesta bakterier orsakar sällan eller aldrig sjukdom, men det finns de som ofta orsakar sjukdom och dessa kallas patogener. För att skydda oss från patogener har vi ett komplicerat och välutvecklat immunfSeminal plasma is semen without the spermatozoa. Human seminal plasma is a complex mixture of secretions from the sex accessory glands, mainly the seminal vesicles and the prostate. Seminal plasma has high protein content and it also contains ions, sugars and low molecular weight components. Immediately after ejaculation the semenogelins and fibronectin aggregate and a coagulum forms trapping the
Popular Abstract in English The dissertation is divided into two parts. The first part deals with the development of a questionnaire diagnostic instrument for atopic dermatitis (AD). The second part concerns following a cohort and assessing the natural history of AD, in which the effect of specified risk factors is analysed. In Värmland, Sweden, a questionnaire that diagnoses AD in infants and preAbstract In childhood atopic dermatitis (AD) is the most frequent inflammatory condition. Validated eczema questionnaires have been available for schoolchildren only, but the incidence of atopic dermatitis is highest during infancy. Evidence is needed on the further development of asthma, and rhinitis in these infants with AD and on remission of AD in children. We aimed to validate a parental ques
Popular Abstract in Swedish Enterohemorragisk Escherichia coli (EHEC) EHEC är mycket virulent för människor, det räcker med så få som 50-100 bakterier för att man ska bli infekterad och utveckla symtom. Varje år rapporteras ca 300-500 fall av EHEC smitta i Sverige. Den stam som oftast isoleras från patienter är E. coli O157:H7. Reservoarer för EHEC är idisslare och framförallt kor. Kor är nämligHemolytic uremic syndrome (HUS) is characterized by non-immune hemolytic anemia, thrombocytopenia and acute kidney failure. The most common form of HUS is associated with gastrointestinal Shiga toxin-producing enterohemorrhagic Escherichia coli (EHEC) infection. EHEC are non-invasive strains with Shiga toxin as the unique virulence factor. The aim of this study was to describe host-pathogen intera
Aim The aim of the thesis is to explore the meaning of the brand within the Knowledge Intensive Business Service (KIBS) sector, through the brand’s construction and management, in order to contribute with insights into the interaction between branding theories and the sector. Theoretical perspective Theories collected and reviewed are focused on three main fields (I) characteristics of the K
The overall goal of this thesis is to examine the effect specific model components, GARCH, EVT and copula, have when examining the possible losses that can occur when holding a portfolio of financial energy contracts within different markets. Daily closing prices of financial monthly forward contracts from 2008-2012 are used in this study. The contracts are in the Nordic and German power markets a
Oroskänslor kan infinna sig när barnet inte mår bra i samband med förlossning. Trots att sådana situationer förekommer, finns det inte mycket forskning om ämnet ur fäders perspektiv. Syftet med studien var att belysa fäders upplevelser när deras barn var i behov av ett akut medicinskt omhändertagande i direkt anslutning till förlossning, i en svensk kontext. Tio intervjuer genomfördes med informan
Issue: The majority of arable land that exists today is already occupied while the population around the world is constantly increasing. New cultivable areas must be explored and developed. Is the construction of greenhouses on existing rooftops in urban environments possible, and how can this benefit a city like Malmö? Purpose: The purpose of this project is to display how a greenhouse may be con
Popular Science Summary Mikroskopiska plastbitar minskar självförsvaret hos rudor I smink, mat och i rengöringsmedel kan man finna mikroskopiska plastbitar. Dessa hamnar i våra vatten eftersom reningssystem inte tar upp dem. De är väldigt små och därför kan de enkelt ta sig in i cellsystem och ta med sig giftiga ämnen. De kan därför vara farliga för fiskar och andra djur i vattnet. Fiskar kan ta
Konceptet SUPPORT strävar efter att hjälpa människor att lättare kunna vila/sova sittandes upp i bilstolen. Med hjälp av stöd som går att dra ut från nackstödet kan huvudet på ett bekvämt sätt lutas mot sidorna och få det stöd som saknas för en bekväm och avslappnad sittställning.
People’s eating habits and how we use the kitchen today has changed extensively over the last few decades. New ways of living and cooking generates a need of rethinking the kitchen and the appliances to better fit the demands and desires of modern living. This concept helps the user include the dishes as an easier part of cooking, and an encouragement to rediscover the health and pleasure of provi
What you see is the result of everything you cannot see As a designer you are expected to design objects. But why do we design these objects and what value do the objects have to their owners and other viewers? Why do humans need to possess objects at all, and how are the objects chosen? Starting this project with poaching in Africa ending up with a 110 kg’s cabinet made out of concrete and ste
Den här uppsatsen beskriver hur verksamhet ser ut på ett servicekontor. Beskrivningen utgår främst från personalens tolkningar och upplevelser av arbetet, arbetsuppgifterna och sin yrkesroll. Fokus ligger på de strukturer som finns i yrkesrollen och inte på de individuella egenskaper som finns hos servicehandläggarna. Jag arbetar själv på ett servicekontor sedan 2 år tillbaka och min utgångspunkt
This thesis is a study of long-term voltage stability in power systems following a severe disturbance. An optimization method for solving the optimal power flow problem is used on power system models. The method tries to optimize the generated active power while fulfilling the requirements from the consumers. Dynamic limitations of the generators are taken into account and an extension of the opt
Background: The ability to hear changes in a sound envelope is called temporal resolution and is assumed to have a key role in binaural speech segmentation. The development of temporal resolu-tion is not fully explored, but studies indicate that it develops into adult-like efficiency at approxi-mately 8-13 years of age, while binaural speech segmentation has an extended development up until approx
Interest in modelling electricity prices has, despite its relatively short history, resulted in widespread types of models that tend to be too intricate to incorporate most price characteristics. This thesis pursues a flexible approach that comprehends stylized facts of electricity prices while it still handles complexity in order to facilitate calibration and forecasting. Although time-varying tr
