During the latter half of the 20th century there has been a continuous decrease in the number of farms in Sweden and agriculture’s importance in economic terms has fallen considerably. This has had significant effects on economic activity in rural areas, on the environment and on the location and size of the food processing industry. Studying the size and the effects of this structural change in a

We present an extensive rheology study of the wormlike micelle system lecithin-water-cyclohexane. In this system the micelles are really wormlike, meaning that there are no signs of micellar branching, as it has previously been demonstrated by NMR self-diffusion experiments (R. Angelico, U. Olsson, G. Palazzo and A. Ceglie, Phys. Rev. Lett., 1998, 81, 2823). Wormlike micelles break and recombine,

The objective of this thesis is to propose a way to introduce social and cultural aspects of environmental degradation to the sustainable development debate. This is done by a reflexive and critical examination of environmental research as it has been applied to different spatial levels (and thus levels of social complexity). The spatial categories discussed are the city, the household and the lan

Cationic liposome-DNA (CL-DNA) complexes, are regarded as promising materials for safe and efficient delivery of genes for therapeutical applications. In order to be used in vivo, these complexes may be coated with a hydrophilic polymer (e.g. polyethylene-glycol, PEG) that provides steric stabilization towards adhesion of proteins and removal by the immune system. In this work we study the influen

Entrained flow gasification of biomass using the cyclone principle has been proposed in combination with a gas engine as a method for combined heat and power production in small to medium scale (<20 MW). This type of gasifier also has the potential to operate using ash rich fuels since the reactor temperature is lower than the ash melting temperature and the ash can be separated after being collec

Phosphorylation of the α-synuclein (α-syn) protein at Ser129 [P(S129)-α-] was found to be the most abundant form in intracellular inclusions in brains from Parkinson's disease (PD) patients. This finding suggests that P(S129)-α-syn plays a central role in the pathogenesis of PD. However, it is at present unclear whether P(S129)-α-syn is pathogenic driving the neurodegenerative process. Rodent stud

Recent data suggest that platelets not only control thrombosis and hemostasis but may also regulate inflammatory processes such as acute pancreatitis. However, the specific role of platelet-derived mediators in the pathophysiology of acute pancreatitis is not known. Herein, we examined the role of CD40 ligand (CD40L, CD154) in different models of acute pancreatitis. Acute pancreatitis was induced

Popular Abstract in Swedish Den nuvarande teknologin inom förbränningsmotorer har möjligheten att hantera den alltmer strikta myndighetskraven på förbränningsmotorn. Emellertid de nödvändiga tekniska lösningarna som krävs är dyra och alltmer tekniskt krävande. En möjlig väg mot enklare efterbehandlingssystem är anvädningen av Homogen Kompressions Antändning (Eng: HCCI) motor cykeln. Den huvudsaklThe current technology within combustion engines have the possibility of handling the more stringent legislative demands on combustion engines. However the required solutions are getting more expensive and technically challenging. One possible way towards a more simple exhaust aftertreatment system is the use of the Homogeneous Charge Compression Ignition (HCCI) engine cycle. The main advantage o

Popular Abstract in Swedish Avhandlingen omfattar förutom en kort inledning, i huvudsak två delar: (1) Beskrivning av teorin bakom ett datorbaserat verktyg för simulering av termodynamiken i ett motorsystem, där främst motorer med Homogen Kompressionsantändning (Homogeneous Charge Compression Ignition, HCCI) avses. Med system avses förutom själva motorn, turboladdare, laddluftkylare, insug och avgThis thesis focuses on engine system simulation using thermodynamics and chemical kinetic models to investigate the performance and efficiency of Homogeneous Charge Compression Ignition (HCCI) engines for stationary applications. It includes the development of software as well as models for engine, turbocharger, intercooler, inlet and exhaust manifolds, wastegate valve, inlet air humidifier, inle

Popular Abstract in Swedish Denna doktorsavhandling i ämnet pedagogik utgör en analys av effekter av den pågående kulturella globaliseringen genom att granska två internationella magisterprogram vid Lunds universitet. Studiens syfte är att spåra mönster i en bärande pedagogisk idé för överföring av ett interkulturellt tänkande i tvärkulturella möten genom att utforska, beskriva och försöka förstå The present study is designed to analyze the effects of the ongoing cultural globalization. It utilizes as its empirical setting two special programmes called the International Master's Programme (the IMP,) directed by Lund University in Sweden. The aim of the study is to infer a pedagogic idea for intercultural transmission through cross-cultural encounters by exploring, describing, and comprehen

In a previous paper we were able to measure the abundance of uranium andthorium in the very-metal poor halo giant BPS CS31082-001, but only obtained an upper limit for the abundanceof lead (Pb). We have got from ESO 17 h of additional exposure on thisstar in order to secure a detection of the minimum amount of leadexpected to be present in CS 31082-001, the am

To date, it is widely accepted that several disorders of the male and female urogenital tract, such as erectile dysfunction, bladder overactivity, urinary stone disease and the benign prostatic syndrome, can be therapeutically approached by influencing the function of the smooth musculature of the respective organs. In order to achieve a pronounced drug effect without significant adverse events, e

Popular Abstract in Swedish Det övergripande syftet med föreliggande studie är att utveckla en bättre förståelse om vad det innebär att vara montessorilärare.

Data exploration has comprised journals, interviews, written reflections and collaborative contextual analysis. Analysis of the teachers' occupational life histories and the findings as a whole have been

Popular Abstract in Swedish Kroppens immunförsvar, vars uppgift är att skydda oss mot infektioner, består av ett antal olika celltyper som till stor del finns i blodet. Immunförsvaret kan indelas i två delar; ett medfött försvar som är likadant hos alla individer och ett försvar som byggs upp under individens livstid. Det senare utformas olika beroende på vilka bakterier och virus som individen utThe cells of the innate immune system are essential for the host's first line defence against infection. Among these cells the neutrophil granulocyte has a central role by the production of antibiotic proteins and peptides. These are targeted for storage in secretory lysosomes and other neutrophil granules for subsequent release by regulated secretion in an inflammatory process. However, the granu

In a warming climate, permafrost is likely to be significantly reduced and eventually disappear from the sub-Arctic region. This will affect people at a range of scales, from locally by slumping of buildings and roads to globally as melting of permafrost will most likely increase the emissions of the powerful greenhouse gas methane, which will further enhance global warming. In order to predict fu

Background: Research involving expressed sequence tags ( ESTs) is intricately coupled to the existence of large, well-annotated sequence repositories. Comparatively complete and satisfactory annotated public sequence libraries are, however, available only for a limited range of organisms, rendering the absence of sequences and gene structure information a tangible problem for those working with ta

?SEPARATE WORLDS?. School librarians teaching in information seeking in high school. The aim of this Master's thesis is to study how information seeking is taught in high school and how school librarians describe their experiences of teaching information seeking. Five school librarians from five different high schools (gymnasium) in Skåne participated in the study. The empirical data derives

Diamonds are regarded to be one of the most valuable natural resources on earth, with an average rough diamond price of $71 per carat in 2000. This gives scope for great economic success in diamond abundant countries. Some of the worlds most diamond abundant countries are found in Africa, ironically also some of the poorest. In recent years it has been brought to the world’s attention that illicit

The research is conducted by an abductive approach using theory and empirical data alternately. Both quantitative and qualitative methods have been adopted in order to see changes in customer behaviour as well as expla
