A 0.5-liter optical HCCI engine firing a mixture of n-heptane (50%) and iso-octane (50%) with air/fuel ratio of 3 is studied using large eddy simulation (LES) and laser diagnostics. Formaldehyde and OH LIF and in-cylinder pressure were measured in the experiments to characterize the ignition process. The LES made use of a detailed chemical kinetic mechanism that consists of 233 species and 2019 re

Popular Abstract in Swedish Avhandlingen utgångspunkt tas från den senmesolitiska boplatsen vid Motala ström, Motala stad, Östergötland, Sverige. Problematiken som diskuteras i texten utgår från frågeställningarna vad som formade de materiella uttrycken under en 500-årig tidsperiod, 5500-5000 f.Kr, dokumenterade genom arkeologiska undersökningar. Texten i avhandlingen är i analysen strukturerad i This dissertation focuses on the Strandvägen site located in the town of Motala, Östergötland, Sweden. The problem concerns what shaped the material expressions on the site during 5500?5000 B.C. For reasons of text structure the space outside the settlement site (the home) is divided into the world, the district, and the neighbourhood. These spatial concepts are finally brought together in the syn

Due to the strongly kinetic nature of the chemical events leading to the formation of mesoscopically ordered inorganic-surfactant composite materials, detailed studies on the interdependency between the degree of inorganic condensation and the co-operative self-assembly is difficult to perform. We have therefore undertaken a study where organic polyelectrolytes are used as models for the inorganic

Two photoproducts of DNA damage, i.e. cyclobutane pyrimidine dimers (CPDs) and 6-4 photoproducts (6-4PPs), induced by UV-B radiation in suspension-cultured tobacco cells were quantified by enzyme-linked immunosorbent assay (ELISA) with monoclonal antibodies. CPDs and 6-4PPs were induced in tobacco cells by UV-B radiation. Photorepair of CPDs was faster than that of 6-4PPs. UV-B radiation induces f

A fundamental assumption of theories of decision-making is that we detect mismatches between intention and outcome, adjust our behavior in the face of error, and adapt to changing circumstances. Is this always the case? We investigated the relation between intention, choice, and introspection. Participants made choices between presented face pairs on the basis of attractiveness, while we covertly

The CEDAR collaboration is developing a set of tools for tuning and validating theoretical models by comparing the predictions of event generators with data from particle physics experiments. CEDAR is also constructing resources to provide access to well defined versions of high-energy physics software and support for software developers. Here we give an overview of the CEDAR project and its statu

Background. Bioincompatible glucose degradation products (GDPs) in fluids for peritoneal dialysis (PD) develop during sterilization and storage. Their biological activity has successfully been monitored through the use of various in vitro methods but their molecular and chemical nature is less well understood. Many GDPs are highly reactive carbonyl compounds. Although some of the identified GDPs a

Although there is no biblical account of the 'Rest on the Flight into Egypt', the story is well known in the Christian world. In pseudo-Matthew the story has developed into legend form. He tells about the Christ-Child commanding the date palm Mary is resting beneath to bend down so that she can eat the fruit. It is found in literary sources from the twelfth century onwards. 'The Rest on the Flight

The adsorption and decomposition of titanium tetrachloride (TiCl4) on W(110) were studied with high-resolution core level photoelectron spectroscopy. At least two stable intermediates are formed along the pathway to TiCl4 decomposition: TiCl4(a), which is stable up to 300 K, and TiCl3(a), which is stable up to 500 K. Successive adsorption at 80 K shows that the TiCl4() species forms in the presenc

This study, based on interviews with army officers, focuses on crying as an action, creating meaning in our interpretation of the world. The discourse of male crying includes the image of a man wanting to express himself emotionally, but unable to because of the traditional ideal of self-control.

The enzyme dUTPase catalyses the hydrolysis of dUTP to dUMP and pyrophosphate, thereby suppressing incorporation of uracil into DNA and providing a pool of dUMP, the precursor of dTTP. Hydrolysis of other nucleotides similar in structure to dUTP would conceivably be physiologically detrimental and high specificity of the reaction seems to be necessary. In this work, we characterize the substrate s

Popular Abstract in SwedishEn del av Ortonys teorimodell angående den kognitiva strukturen hos emotioner testades på svenska gymnasieelever. Den del av teorin som användes i föreliggande studie handlade om de emotioner som tillskrivs den som utfört s.k. orätta handlingar. De eventuella känslor som man får när man utfört en orätt handling kallar Ortony för "self reproach" emotioner. Detta begrepp sThe purpose of this study was to test parts of Ortony's theoretical model relating to the cognitive structure of emotions in Swedish upper secondary school students. That part of the model, which was appropriate for the present study, deals with emotions attributed to the person who has perpetrated what is referred to as blameworthy actions. Ortony calls the possible emotions that you experience w

Radiolabelled monoclonal IgM rheumatoid factors, four from patients with type II essential cryoglobulinaemia and one originating from a patient with rheumatoid arthritis, were tested for binding to group A, B, C and G streptococci and Escherichia coli. Two of the preparations exhibited different binding patterns for the streptococci, whereas the remaining three were not reactive. The binding of on
