Abstract in UndeterminedCompanies in the food industry are driven to improve their traceability for several reasons. The primary reasons are food safety and quality. Another is the response to the increased interest among consumers in imperceptible product attributes such as organic, fair trade, dolphin-safe and non genetically modified (non-GMO). Such attributes are hard to distinguish and thus r
Internal combustion engines are continuously developed towards decreased hazardous emissions and lower fuel consumption. The homogeneous charge compression ignition (HCCI) engine is a promising concept which combines the best features of the Diesel engine and the spark ignition (SI) engine. The efficiency is in the range of the Diesel engine and the emissions are low and comparable to the emission
Researchers who desire to bring about change in organizational settings require approaches to inquiry which can go beyond superficial appearances and prejudice. In seeking to go beyond mere examination of socio technical systems researchers have developed a proliferation of different approaches. Many of these have drawn upon social and human sciences to ground methods and assumptions in philosophi
This Norm focussing article starts exploring the various influence processes that take place in connection with the dawn of a new theme - the environment and then sustainable development - in today's society. The Swedish society has in the early 1990-ies declared that educational institutions, places designed for the intentional influence, shall utilise the new environmental theme in its practice.
Popular Abstract in Swedish Lunds strängfragmenteringsmodell beskriver hur färgade partiklar (kvarkar och gluoner, tillsammans kallade partoner) som produceras vid högenergetisk partikelkollisioner omvandlas till färgneutrala hadroner. Denna avhandling utvecklar och utforskar ett alternativt tillvägagångssätt till modellen. Den nya infallsvinkeln förbättrar modellen för system som består av många
Popular Abstract in English This dissertation attempts to answer the question of why the 2003 armed conflict against Iraq received such varied support within the United States, the United Kingdom, Australia, France and Spain. This is achieved by introducing a model in which the support for armed conflict is connected to elite persuasion operating in particular contexts. This model is tested in a cThis dissertation attempts to answer the question of why the 2003 armed conflict against Iraq received such varied support within the United States, the United Kingdom, Australia, France and Spain. This is achieved by introducing a model in which the support for armed conflict is connected to elite persuasion operating in particular contexts. This model is tested in a comparative study, using inte
Popular Abstract in Swedish Jag har i den här avhandlingen behandlat problemställningar inom tre olika områden inom astronomin. Det som sammanlänkar dessa är att alla innefattar dubbelstjärnor där avståndet mellan stjärnorna är litet, dvs de har en kort period. De är också alla datorsimuleringar. Jag har satt upp en modell för att betrakta de astronomiska systemen och genom numeriska metoder beräkThis thesis introduces and summarizes four papers dealing with computer simulations of astrophysical processes involving binaries. The first part gives the rational and theoretical background to these papers. In paper I and II a statistical approach to studying eclipsing binaries is described. By using population synthesis models for binaries the probabilities for eclipses are calculated for diff
Stylistic Fronting (SF) is a process that fronts various types of non-subjects to the preverbal position in subjectless clauses (“that gone have”, etc.). With the exception of Icelandic and to some extent Faroese, SF has disappeared from Scandinavian varieties. It is commonly assumed that even in Icelandic it is formal and old fashioned, indicating that it might be on its way out of this language
Popular Abstract in Swedish Hudfibros, inre organengagemang och autoantikroppar vid systemisk skleros: longitudinell utveckling och effekt på överlevnad. Systemisk skleros kallas ofta för sklerodermi. Sjukdomen tillhör de systemiska bindvävssjukdomarna och handläggs i Sverige oftast av reumatologer. Kardinalsymtomet vid sklerodermi är förhårdnad hud vilket gett sjukdomen den dess namn. Sklero betySystemic sclerosis (SSc) is a connective tissue disease with a highly variable prognosis. Since new treatment strategies are emerging, there is a need for prognostic markers in order to help allocate patients to the optimal treatment. When comparison is made to the general population, there is an increased mortality rate in this study, both in the series as a whole and in the subgroups of men and
Purpose of this paper The purpose of this paper is to present a comparative case study of the procedures and guiding principles in the packaging selection practice of two international companies. Design/methodology/approach A qualitative case study with an inductive approach was conducted. The data was collected through semi-structured interviews, documentation, and field visits. Findings Th
It has previously been shown by the authors that the pre-chamber ignition technique operating with fuel-rich pre-chamber combustion strategy is a very effective means of extending the lean limit of combustion with excess air in heavy duty natural gas engines in order to improve indicated efficiency and reduce emissions. This article presents a study of the influence of pre-chamber volume and nozzl
An extensive research program, dealing with fire growth on combustible wall lining materials, has been ongoing in Sweden over the last decade. Several lining materials were tested in bench-scale fire tests in order to derive basic material flammability parameters. The same materials were also tested in a full scale room test and a 1/3 scale room test for two different scenarios, A and B. Scenario
Major Asian cities like Hong Kong, Taipei and Bangkok have been constantly on the verge of rapid transformation, whether politically, socially, and particularly sexually, due to the process of capitalisation, modernisation, and globalisation over the last decade. In response to the impact of the transformation on the historical and traditional space of the city, the region's unique cultural and hi
Recent research on life in extreme environments has shown that some microorganisms metabolize at extremely low temperatures in Arctic and Antarctic ice and permafrost. Here, we present kinetic data on CO2 and (CO2)-C-14 release from intact and C-14-glucose amended tundra soils (Barrow, Alaska) incubated for up to a year at 0 to -39 degrees C. The rate of CO2 production declined exponentially with
The autonomic nervous system (ANS) and hypothalamic-pituitary-adrenal (HPA) axis are reported as activated in excess in the morbidly obese state and, therefore, changes after weight loss can be anticipated. The aim of this study was to investigate the impact of a massive (similar to30%) weight reduction on the activation of the HPA axis and the ANS following bariatric surgery. Eight (7 women, 1 ma
The prototypical antimicrobial peptide, melittin, is well-known for its ability to induce pores in zwitterionic model lipid membranes. However, the mechanism by which melittin accomplishes this is not fully understood. We have conducted all-atom and coarse-grained molecular dynamics simulations which suggest that melittin employs a highly cooperative mechanism for the induction of both small and l
The objective of this work is to establish under which conditions short RNA molecules (similar to miRNA) associate with zwitterionic phospholipids and how this differs from the association with cationic surfactants. We study how the base pairing (i.e., single stranded versus double stranded nucleic acids) and the length of the nucleic acid and the charge of the lipid/surfactant monolayer affect th
The oxidation of biogenic volatile organic compounds (BVOCs) gives a range of products, from semi-volatile to extremely low-volatility compounds. To treat the interaction of these secondary organic vapours with the particle phase, global aerosol microphysics models generally use either a thermodynamic partitioning approach (assuming instant equilibrium between semi-volatile oxidation products and
