Due to the nature of the engine cycle, heat transfer has a significant role in the estimation of engine efficiency. The effects are quite well known in the classic combustion concepts, compression ignition (CI) and spark ignition (SI) combustion. But for the newer, low temperature combustion (LTC) concepts, these effects are not that well known. In this paper, a commercial computational fluid dyna

Popular Abstract in Swedish Avhandlingen syftar till att utifrån 11-åriga barns berättelser om sina familjer och hur de själva uppfattar sina familjer och sin fostran beskriva, analysera, förstå och tolka villkoren för denna fostrans- och socialisationsprocess samtidigt som den pågår. Forskningsproblemet kan formuleras: hur och vad uppfattar och berättar barn om sina upplevelser av familjeliv och The thesis aims to describe, analyse and interpret the conditions of the upbringing process and the socialization process in a group of eleven-year-olds while the process is still ongoing, and to do this with the help of the eleven-year-olds? narrations about their families and about how the children themselves view their families and their upbringing. The research approach is inspired by phenomen

In this work radiative properties of neutral elements with one or two electrons outside closed subshells have been investigated. Using laser techniques in connection with atomic beams selective excitation of Rydberg states was performed. Most of the studied states were populated with two-step excitation. Some states were reached directly from the ground state or from a metastable state and occasio

Traditionellt sett hör idrotten och den fysiska leken ungdomen till, men idag är det inte ovanligt med regelbunden och målinriktad motion också högre upp i åldrarna. Samtidigt har idrotten blivit allvarligare och forskningen betonar starkt och entydigt sambandet mellan ett livslångt motionerande och ett hälsosamt liv. I denna studie belyses motions- och hälsostrategier hos äldre män och kvinnor sa

How can we create sustainable agriculture, capable of feeding the soon to be 10 billion people of the earth, and at the same time preserve the ecosystems of the species that coexist with us on this planet? A team from Lund University in Sweden attempts to answer this tricky question.

Artikeln diskuterar dygdens ställning i 1700-talets Sverige - hur den diskuterades och legitimerades i dåtidens sedeläror. Förnöjsamhet var en särskilt populär dygd och dess relation till samhälleliga hierarkier ger oss en insyn i dåtidens moraliska landskap. Det ger oss även en uppfattning om hur tänjbara de moraliska gränserna kunde vara och vilka möjligheter som fanns att argumentera mot de råd

This is an attempt to write a popular book on mysticism, as requested by one of the largest publishers in Sweden (Natur och Kultur). Twelve mystics, representing Judaism, Christianity, and Islam, met in Andalusia (Córdoba) in order to discuss how spiritual leaders could contribute to increasing understanding between different cultures. When discussing their concept of God, view of man, mystical te

Non-state actors have been increasingly engaged in regulation, operating and setting rules outside of, and parallel to, existing legal institutions. These “alternative to legal rules” have been increasingly influential in domestic law and policy, with growing evidence of them penetrating legal, professional, as well as social orders. This thesis adopts the case of sustainability assurance to analy
