Gasoline partially premixed combustion (PPC) has the potential of high efficiency and simultaneous low soot and NOx emissions. Running the engine in PPC mode with high octane number fuels has the advantage of a longer premix period of fuel and air which reduces soot emissions. The problem is the ignitability at low load and idle operating conditions.In a previous study it was shown that it is possGasoline partially premixed combustion (PPC) has the potential of high efficiency and simultaneous low soot and NOx emissions.

Intermittently incubating birds alternate between sessions of egg warming and recesses for foraging during the day, but stay on the nest continuously at night. Hence, energy costs of nocturnal incubation (which increase during longer and colder nights) cannot be replenished until the next day. Night conditions might therefore be expected to affect morning incubation behaviour the day after. We tes

Utomhusbelysning i offentliga miljöer har en viktig roll i en hållbar stadsutveckling. Energieffektiv LED-belysning kan stödja mobilitet i stadsmiljöer och medverka till en ökad tillgänglighet för personer med särskilda behov.

I naturen fångas solljus in via ljus-absorberande molekyler. På liknande sätt kan färgämnen användas för solcells- och artificiell fotosyntes-applikationer för att absorbera solljus, och överföra den exciterade elektronen.Framgångsrika färgämnen har tidigare varit baserade på Ru-polipyridyl-komplex, trots att Ru är ett av de mest ovanliga ämnena i jordskorpan. Detta arbete har som mål att ersätta Nature captures sunlight via light-absorbing molecules.Similarly, photosensitisers are used in applications of solar cells and artificial photosynthesis to absorb sunlight, and transfer the excited electron.Successful photosensitisers have in the past been based on a Ru polipyridyl scaffold, despite Ru being one of the scarcest elements in Earth's crust.This thesis work aims to replace Ru polipyri

Older women make a significant contribution to the labour market yet still experiencenegative workplace impacts. We undertook a rapid review of literature to assess theexperiences of older female workers in the European labour market with the aim toidentify current research gaps. We discuss how current data and future research couldbe utilized to improve the working lives of older women in Europe.

The adsorption from a mixture of SDS and β-Lactoglobulin, 1:5 (), onto a methylated silica surface was studied in situ by ellipsometry. The amounts adsorbed from different concentrations of the mixture, at pH 7, were compared with those adsorbed from the corresponding pure SDS and β-lactoglobulin solutions. At high concentrations of the mixture, where the CMC of SDS is approached or exceeded, the The adsorption from a mixture of SDS and β-Lactoglobulin, 1:5 (), onto a methylated silica surface was studied in situ by ellipsometry.

The purpose of the research was to investigate the effects of visual ergonomics interventions on eyestrain, musculoskeletal discomfort, headache, and visua

Popular Abstract in Swedish Hur kan man förklara vardagligt tänkande med de kognitiva teorier som finns tillhands idag? Ofta är dessa teorier konstruerade för att kunna förutsäga beteende under kontrollerade omständigheter, som i ett laboratorium. Å andra sidan är det snarare flexibilitet och improvisation som kännetecknar det vardagliga tänkandet. I avhandlingen försöker jag ta reda pa vad man måHow well can we explain natural occurrences of cognitive behaviours given the theoretical frameworks available to us today? The thesis explores what has to be assumed in cognitive theory in order to provide such an explanation, in contrast to being able to predict behaviour under controlled circumstances. The behaviours considered are all of the type described as involving higher level cognition

This thesis explores the relationship between the position, function and semantics of the German particle "also" (?so?). Traditionally, "also" is classified as a conjunctional adverb because it can fill the position in front of the finite verb in the German clause, the so-called "Vorfeld" (?pre-field?). In this position, it has a meaning similar to that of a conjunction but a distribution similar

This PhD-thesis in Sociology of Law studies ”Law in Progress” by investigating norm-generating processes, which emerge through an interaction between actors over time. The thesis has an empirical approach, thus illustrates these processes through an empirical example, a European “Earth Observation” (EO) initiative: Global Monitoring for Environment and Security (GMES). The main research questions

Popular Abstract in Swedish Papillomvirus (PV) är små virus som förmodligen infekterar alla däggdjur samt fåglar. De papillomvirus som infekterar människa kallas humant papillomvirus (HPV) och kan infektera antingen huden eller slemhinnor. Att livmoderhalscancer orsakas av bestående infektion med HPV har varit känt länge. Man har länge också misstänkt att HPV-infektioner i huden kan orsaka icke-meThe causal relationship between persistent genital infections with human papillomavirus (HPV) and development of cervical cancer is well established. In contrast, the significance of infections with cutaneous HPV for development of non-melanoma skin cancer (NMSC) is not well understood. We have evaluated whether seropositivity to cutaneous HPV is a marker for cutaneous HPV infection and used high

Tidigare forskning om samverkan visar att samarbete innefattar problem och konflikter. Syftet med denna studie är att istället beskriva mer framgångsrik samverkan även om denna utspelas under kortare interaktionsfrekvenser. I boken diskuteras forskning som analyserat framgångsfaktorer men framförallt analyseras ett eget empiriskt material med fokus på hur och när aktörerna inom ungdomsvården framsPrevious collaboration research shows that problems and conflicts sometimes arise as a part of collaboration. This book analyzes successful cooperation unfolding during shorter interaction sequences. In this study I endeavour to describe the contributing factors that are necessary to achieve the phenomenon of a successful collaboration. I do this partially with help from studies published in previ

Popular Abstract in Swedish Mörkerseendet är en mycket känslig nervfunktion och mycket känsligare för låg syrgastillförsel än högre mentala funktioner. Mörkerseendet är kraftigt reducerat hos patienter med två kliniskt sett så olika tillstånd som förträngd halspulsåder (carotisstenos) och "trögflytande blod" (polycytämi). Gemensamt för båda patientgrupperna är en under lång tid störd blodcirculatiPurpose: To study dark adaptation in patients with symptomatic carotid artery disease or polycythemia before and after treatment. This necessitated determinations of pupillary changes as such may influence the findings. To determine whether changes in the retinal blood flow in light and darkness occur in healthy humans. Methods: Repeated automatic dark adaptometry was recorded monocularly in 21 c

Popular Abstract in Swedish Klorofyllsyntes är en viktig process i naturen. De gröna pigmenten utgör en viktig del i fotosyntesen där de absorberar och överför solenergi till fotosyntetiska reaktionscentra. Magnesium kelatas katalyserar insättandet av en magnesium (II) jon i protoporfyrin IX, vilket är det första specifika steget i klorofyllsyntesen. Magnesium kelatas består av tre proteiner, som The biosynthesis of chlorophylls is an important process in nature. The green pigments play a fundamental role in absorbing and transferring solar energy to the photosynthetic apparatus. This thesis elucidates the role and function of the enzyme magnesium chelatase, which catalyses the insertion of magnesium (II) into protoporphyrin IX and is the first committed enzyme of the chlorophyll biosynthe

Popular Abstract in English Bolivia, as with other Latin American countries, is considered to be in an epidemiological transition due to the continued persistence of infectious diseases, and nutritional deficiencies related to poverty and food insecurity, together with an increase in chronic non-communicable diseases mainly related to lifestyle factors. The work presented in this thesis was focuseThe synergistic relation between nutritional deficiency and infection may have negative effects on the immune system, making individuals more vulnerable to infection. Zinc can affect the resistance to infections by modulating cytokine release, and by acting as a cofactor of thymulin, which induces the differentiation of immature T lymphocytes. To investigate the modulation of the immune response b
