Partially premixed combustion (PPC) is a promising way to achieve high thermal efficiency and low emissions, especially by using multiple injection strategies. The mechanisms behind PPC efficiency are still to be explained and explored. In this paper, multiple injections have been used to affect the gross indicated efficiency in an optical PPC engine modified from a Volvo MD13 heavy-duty diesel en

This study investigated age-related changes in the human brain function using both traditional EEG analysis (power spectra) and the correlational dimension, a measure reflecting the complexity of EEG dynamics and, probably, the complexity of neurophysiologicaI processes generating the EEG. Assuming that the accumulation of individual experience is determined by the formation of functionally relate

The treatment of rheumatoid arthritis is currently based on pathogenesis and pathophysiology, being the etiology still unknown. At cognition and activation phase of rheumatoid arthritis, there is a number of potential therapeutic approaches, still in development and in early trials. At inflammation and even more at invasive phase of rheumatoid arthritis, the treatment should take into consideratio

This is a study of contemporary feature films and short films presenting personal and collective traumas originating in Levantine Middle Eastern conflicts – in Israel, Lebanon, Palestine and Syria. Just after the millennium there were significant shifts in these societies and consequently in their cinemas. A number of films received both international attention and awards. This essay seeks to inve

This study seeks to investigate the nature of ownership of land and how the right to its control and use can be inferred from self-ownership as a premise. Hence, the question asked is how ownership (of land) can be justified considering the nature of man from a natural rights point of view. The starting point for the argument is self-ownership as being, where man is identified as an indivisible e

Adjustable magnetic field sources have become indispensable in advanced material characterization techniques. Among these, permanent magnet assemblies offer significant advantages by reducing power consumption and minimizing Joule heating. In this work, we report on the development and integration of a tunable magnetic sample environment at the SoftiMAX beamline of the MAX IV synchrotron, employin

The increased impact from fluctuating energy sources like wind and photovoltaics significantly affects the operational regime of conventional power plants. In the near future, even former base load power plants such as the large-scale lignite plants in Germany will need to start and shut down to balance the electricity system. As frequent starts were not in the focus of optimisation in the past, a

During the past few decades, the Swedish spatial planning system has experienced numerous problems and challenges. In particular, there have been changes in legislation and an increased neoliberalisation of planning that gives private actors a larger influence over the planning processes in Sweden. In this article, we analyse these changes through the lenses of collaborative and neoliberal planninDuring the past few decades, the Swedish spatial planning system has experienced numerous problems and challenges.

In plants the chloroplast thylakoid membrane is the site of light-dependent photosynthetic reactions coupled to ATP synthesis. The ability of the plant cell to build and alter this membrane system is essential for efficient photosynthesis. A nucleotide translocator homologous to the bovine mitochondrial ADP/ATP carrier (AAC) was previously found in spinach thylakoids. Here we have identified and c

Abstract in UndeterminedA central part of relational ties between social actors is constituted by shared affiliations and events. The action of joint participation reinforces personal ties between social actors as well as mutually shared values and norms that in turn perpetuate the patterns of social action that define groups. Therefore the study of bipartitenetworks is central to social science.

Popular Abstract in Swedish Oberoende av om det är i ett samhälle, datornätverk eller organen i en mänsklig kropp, så är behovet av kommunikation stort i en komplex miljö. Eftersom den komplicerade människokroppen är beroende av kommunikation för att reglera funktioner, skickas otaliga mängder signaler oavbrutet. För att signalerna skall vara meningsfulla så måste de kunna tas emot och behandlas.

Gender scholarship has identified how paid care work reproduces male dominance and reinforces women's subordination, but also how labour and workplaces provide a critical space for women through the development of new forms of identity and struggle. In this ethnographic study of Swedish nurses' work, the concept of normative femininity is used in order to explore gender, labour, and changing relat

The crystal structures of the main Portland cement clinker phases are reviewed and two anion centered models of Ca3SiO5 and Ca2SiO4 are presented. The effects of minor elements on the clinkering process, and on the qualitative and quantitative phase compositions of Portland cement clinker are discussed. The distribution of some minor elements (F, Na, Mg, S, K, Ti, Mn, and Sr) has been investigate

Popular Abstract in Swedish Kärleksdofter och varningsljud i bekämpning av nattfjärilar Jag har studerat hur populationer av skadegörande nattfjärilar kan bekämpas med miljövänliga metoder där djurens egna sinnessystem manipuleras. Liksom många andra insekter kommunicerar nattfjärilar med artspecifika doftsignaler (feromoner) vid parning. Honan avger doften i enstaka nanogram (miljarddels gram!) The impact of olfactory and auditory cues on the mating behaviour in two species of moths, Agrotis segetum (Noctuidae) and Plodia interpunctella (Pyralidae), was investigated to evaluate their potential use in integrated pest management. The flight behaviour of male A. segetum under natural and pheromone-based mating disruption conditions was monitored by harmonic radar. Individual males were equi

A three-dimensional (3D) direct numerical simulation (DNS) of an experimental turbulent premixed jet flame at high Karlovitz number was studied. The DNS resolution adequately resolves both the flame and turbulence structures. A reduced chemical mechanism for premixed CH4/air flames with NOx based on GRI-Mech3.0 was used, including 268 elementary reactions, and 28 transported species. Consistent po

Urban densification is a way of accommodating population growth. Land adjacent to railways is used for constructing residences and other buildings, and new tramway systems are planned. Under these circumstances, nearby buildings will be exposed to vibrations and noise that may become a nuisance for the residents. It is necessary, even at an early stage of planning, to assess the extent of the vibr
