Achieving a robust ignition with minimal spark plug wear is challenging in heavy duty engines fueled with gaseous fuels like biogas and hydrogen. Thermal energy deposition from the spark to the gas was studied in a 10.9 milliliter custom-built spark calorimeter. An AC capacitive ignition system was used along with a dual-nickel standard J-gap spark plug and the influence of multiple physical and e

Efter att ha sett allt fler ladugårdar som förfaller bestämde jag mig för att göra ett arbete om just denna byggnad. Jag ville undersöka vad ladugården är och hur det kan vara möjligt att bevara och ta hand om den. Genom att skaffa kunskap om ladugårdens historia ville jag få en fördjupad insikt om vad dessa byggnader egentligen har för betydelse. Med hjälp av referensprojekt och genom att gestalAfter seeing more and more barns decaying, I decided to make a project about this particular building. I wanted to investigate what the barn is and how it may be possible to preserve and take care of it in the future. By gaining knowledge about the barn’s history, I got a in - depth insight into what these buildings really mean. By looking at reference projects and by transforming a existing barn,

Vätgas är en energibärare som kan ha en roll i fossilfria energisystem. I det här examensarbetet undersöktes därför den praktiskt genomförbara potentialen för förnybar vätgas att göra nytta i Skånes energisystem inom tidsramen till 2030. Detta analyserades genom en undersökning av de tekniska och regionala förutsättningarna för förnybar vätgas, en intervjustudie med sju skånska vätgasaktörer, samtHydrogen is an energy carrier that could be a part of fossil free energy systems. That is why the practicable potential of renewable hydrogen to benefit the energy system of Scania, Sweden, within the time frame of until 2030 was evaluated in this report. This was done through reviewing the technical and regional conditions and through interviews with seven regional actors involved in hydrogen, as

After the ratification of the UN Convention, Sweden has undertaken to adapt national laws so that they conform to the Convention of the Rights of the Child, CRC. Despite the ratification, the Care of Young Persons Act (LVU) allows young persons to be separated up to 24 hours by the staff at state institutions, even though it is contrary to the CRS’s 37th article. The ombudsman for children has rep

Arbetet är en examensuppsats på termin sex vid Ekonomiska Högskolan Lund, systemvetenskapligt kandidatprogram. Arbetet skall skänka ett mindre kunskapsbidrag inom Informatik och behandla kritiska framgångsfaktorer för ERP-implementationer. Vi har utgått ifrån en förundersökning på rådande empiri inom ämnet för att avgränsa oss till ett urval nyckelfaktorer, som sedan undersökts med datainsamling i

In our response, we address four themes arising from the commentaries. First, we discuss the distinction between cognition and metacognition and show how to draw it within our framework. Next, we explain how metacognition differs from social cognition. The underlying mechanisms of metacognitive development are then elucidated in terms of interaction patterns. Finally, we consider measures of metac

Bytecode folding is an effective technique for speeding up execution in Java virtual machines. This paper investigates a hardware implementation of the aforementioned technique on BlueJEP, a Java embedded processor. Since BlueJEP is a micro-programmed stack machine, we adopt a micro-instruction oriented approach, folding up to four microinstructions (corresponding to up to four bytecodes, on occas

The increasing semiconductor functionality relies on more complex integrated circuits with higher component densities. Miniaturisation and its implications on resource consumption in semiconductor facilities have been fairly well explored in a number of life cycle assessment (LCA) studies, which show that, in spite of the growing product complexity, resource intensities per product unit are gradua

The infrastructure for the third generation of mobile telephony, UMTS, is under construction in Sweden. Within three years four operators were to build competing systems to cover 99,98 % of the population. The case of the 3G infrastructure illustrates how the sustainability issues are handled in planning and environmental management, with conflicting goals between institutional levels and compet

The article presents an analysis of boundary work within the context of care for the elderly, where violence appears to be widespread though still relatively unacknowledged. By resorting to certain descriptive – often jocular – modes, the staff designate aggressive acts committed by patients as 'non-violent'. This occurs although intent, responsibility, and injury – all common criteria associated

I denna artikel analyseras muntligt gestaltade erfarenheter hos 27 överlevande efter kriget i nordvästra Bosnien under 1990-talet. Syftet är att dels beskriva hur de intervjuade framställer det sociala fenomenet «offerskap», dels analysera diskursiva mönster som medverkar i konstruktionen av kategorin «offer». Aktörernas anspråk på statusen «offer» skapar en konkurrens om offerrollen efter kriget.The aim of this article is to analyse verbally portrayed experiences of 27 survivors of the 1990’s war in northwestern Bosnia. My focus is on describing how the interviewees portray the social phenomenon of «victimhood» and on analysing the discursive patterns that contribute to construction of the category «victim». When, after the war, different actors claim this «victim» status, it sparks a com
