Development and application of some laser techniques for the study of engine combustion are presented. The investigations mainly cover two aspects: fuel dynamics and formation of NO. Fuel dynamics is one of the most central problems in engine design since many performance parameters are affected by it; emission formation, efficiency, drivability etc. The studies include cycle-resolved measurement

We review the theoretical motivations and experimental status of searches for stable massive particles (SMPs) which could be sufficiently long-lived as to be directly detected at collider experiments. The discovery of such particles would address a number of important questions in modern physics including the origin and composition of dark matter in the universe and the unification of the fundamen

Family caregivers experience both positive and negative reactions in caregiving situations. There has been considerably less published about the positive aspects, however. The general aim of this study was to explore a previously developed instrument to study rewards gained by caregivers and to determine the factors associated with satisfaction in family members caring for patients with dementia l

In this report the moisture conditions and the moisture diffusivity of the concrete and its variations are estimated by computer calculations.

Det finns många situationer där data är hierarkiskt uppbyggda och där flernivåanalyser kan komma i fråga. Metoderna måste dock anpassas till frågeställningen, och modellerna måste kontrolleras mot data.

The chondroitin/dermatan sulfate proteoglycans (CS/DSPGs), biglycan, decorin, and versican play several important roles in extracellular matrix influencing matrix organization, cell proliferation, and recruitment. Moreover, they bind and regulate growth factors in the extracellular matrix. We have previously shown that cultured human lung fibroblasts treated with transforming growth factor-beta (T

Popular Abstract in Swedish En hjärtinfarkt definieras som celldöd i hjärtmuskeln, och om celldöden är omfattande, orsakar den en oåterkallelig nedsättning i hjärtats pumpfunktion. Pumpfunktionen kan även vara långvarigt nedsatt p.g.a. att hjärtat inte får tillräckligt med blod. Man kan då förbättra pumpfunktionen genom att återställa blodtillförseln med en operation. För att kunna hitta områden iThe assessment of ischemic heart disease (IHD) often focuses on the detection of dysfunctional but viable myocardium which may improve in function following revascularization. Dysfunctional but viable myocardium is identified by distinct characteristics with regards to function, perfusion and viability. Therefore, in Paper I we developed a method for quantitative polar representation of left ventr

Abstract in French Le but de l’étude présente est de démontrer que la distinction entre le langage plastique et le langage iconique, introduite par Floch et Groupe µ, reste utile, à condition de la faire subir une série de modifications : d’abord, il ne faut pas parler du langage iconique, mais du langage pictural, parce que l’iconicité peut très se retrouver aussi bien du côté plastique. Ensuite,The task of the present study is to establish the useful of the distinction between plastic language and iconic language, as introduced by Floch and the Groupe µ, with the proviso that it has to be changed in a number of ways. To begin with, we should not talk about iconic language, but rather about a pictorial one, because iconicity is a much broader concept, and just as probably may found on the

GEANT4 is a Monte Carlo code originally implemented for high-energy physics applications and is well known for particle transport at high energies. The capacity of GEANT4 to simulate neutron transport in the thermal energy region is not equally well known. The aim of this article is to compare MCNP, a code commonly used in low energy neutron transport calculations and GEANT4 with experimental resu

A new method for collection of group data is described— Group Diary. Document studies in psychology are a background. Group members collect data as recorders and synthesize their notes. The method is a tool for learning, research and consultation. Methodological issues are elucidated. After presentation of five studies on group formation and development done by the authors, the pros and cons of th

The libels written against queen Christina of Sweden are analyzed,and compared to the libels against cardinal Mazarin. Christina is accused of sexual misbehaviour, Mazarin is not. The rules governing the female conduct is clearly different from the rules governing male conduct.

Popular AbstractI den här avhandlingen behandlas dels hur själva organiseringens processer kan gestalta sig, dels innehållet i några av de studerade processerna. Det empiriska materialet i studien har hämtats från fyra industriföretag som alla under 1990-talets första år genomförde försök att utveckla en mera processorienterad arbetsorganisation. Tre av företagen ingår i globala koncerner. Det fjäThe focus of this dissertation is on organizational change in four industrial corporations. A special emphasisis placed upon the symbolic and rhetorical aspects when changing organizations. Main concepts in the study are symbolic management and management of meaning. Two main areas are discussed in the dissertation. Firstly, how the new organizational meaning is constructed or produced. Secondly,

Cadmium is a well-known nephrotoxic agent in food and tobacco, but the exposure level that is critical for kidney effects in the general population is not defined. Within a population-based women's health survey in southern Sweden (Women's Health in the Lund Area, WHILA), we investigated cadmium exposure in relation to tubular and glomerular function, from 1999 through early 2000 in 820 women (71%
