This article deals with application of a pre-chamber type ignition device in a heavy duty engine operated with natural gas. A particular pre-chamber ignition strategy called Avalanche Activated Combustion (originally ’Lavinia Aktyvatsia Gorenia’ in Russian), commonly referred to as LAG-ignition process, has been studied by performing a parametric study of various pre- and main chamber mixture stre

Realist arguments are a combination of two discrete, though often intersecting, literatures. The first emerging from the works of classical realists such as Thucydides and Machiavelli, and the second spreading across the history of Western philosophy. One of the most significant aspects of realism is its use of historical evidence, as if one can detect a timeless wisdom of world politics centred u

This account of genocide in the twentieth century contains a) a description of cases, b) an interpretation of different mechanisms of genocide and c) a comparative analysis of genocides as a historical phenomenon in the modern era. The text is divided into sections that are interrelated. The introduction gives a general background to the concept, describes the Genocide Convention and defines the

Popular Abstract in Swedish Sammanfattning på svenska Muskelvävnad är specialiserad på att förkorta sig och utveckla kraft. Glatt muskulatur finns i blodkärlens väggar, i urinvägarna, i luftvägarna samt i mag-tarmkanalen, och är viktig för dessa organs funktion. Namnet "glatt" (smooth) härrör från muskulaturens utseende i mikroskop. Den glatta muskulaturen ser slät ut, i motsats till det "randiga"Smooth muscle is characterised by high tension economy, low shortening velocity and regulation mainly by myosin light chain (MLC) phosphorylation. The aim of this study was to investigate regulation of force and maximal shortening velocity (Vmax) in smooth muscle. In intact muscle, activated with depolarisation, inhibition of force and rise in intracellular [Ca2+] ([Ca2+]i) by 2,3-butanedione mono

The environment in which our cognitive processes operate is crucial for understanding their current form, their reliability, and their function. In the following pages I will look at the role the environment plays in psychological explanations of cognitive behaviour, also when the explanations are not of an evolutionary character. In particular, I will focus on how environmental considerations (br

Popular Abstract in Swedish Det övergripande syftet med denna avhandling var att studera sambandet mellan skelettmuskulaturens struktur och funktion för att på sikt få ökade kunskaper om de bakomliggande mekanismerna vid muskulär svaghet och uttröttbarhet hos personer med olika skador eller sjukdomar. Mätningarna valdes att göras på musklerna på underbenets framsida, ankelns dorsalflexorer, dels sThe overall aim of this thesis was to increase our knowledge of the relationship between structure and function of human skeletal muscle, and about factors affecting strength. The ankle dorsiflexor muscles (DF) were chosen as a representative model of human skeletal muscle, and because these muscles have important roles in gait and maintenance of balance. Specific aims in this thesis were: i) to d

Popular Abstract in English Parasites and their host organisms have engaged in a desperate battle over millions of years to evolve strategies that enable continued survival of their respective species. Parasites require some key metabolites to be able to survive and reproduce inside the host that often results in damage to host, while host organisms attempt to limit or prevent this damage by severHaemosporidia is a well-studied group of parasites, which infect mammals, reptiles and birds and use blood sucking vectors for their transmission. By conducting natural population studies and experimental infections, We have been able to detect and quantify Haemosporidia from avian blood to investigate how these pathogens affect their avian hosts. We have used life history data of two long-term lo
