The purpose of this study was to investigate the applicability of data-driven experimental design for the optimization of a hard coating for cutting tools in metal machining. The complexity of metal machining leads to difficulty in theoretically modeling and understanding the interactions and correlations between parameters and performance. Because of this and the importance of incremental perform
To reduce the use of resources, as well as to minimize the effluents of carbon dioxide; we need to use our products for a longer time. Repairs makes that possible and is considered a key strategy to move towards a more circular economy (CE). Sweden recently presented its CE action plan, which includes few direct initiatives that would foster repairs. Therefore, through a literature review, policy
The production of single cell biomass by the collaboration company in this project for use as a meat alternative is a potential source of sustainable alternatives to functional ingredients for the food industry. With its high protein content, creating a protein isolate from the single cell biomass became interesting and a study of single cell protein functionalities could offer a possibility to in
Narkotikabruk leder ofta till skador på den fysiska och psykiska hälsan. Konsekvenserna av att bruka narkotika är bland annat försämrad impulskontroll, leversjukdomar, psykoser och ökad risk att dö i förtid. Därtill kan det råda svårigheter att sluta nyttja droger eftersom den missbrukande individen upplever abstinensbesvär. Varför en del människor börjar använda droger kan exempelvis vara att de
Swedish youth-centres are characterized by their vision of being a “meeting place for all”. To fulfil this vision, inclusion has become a relevant concept and tool for those working within these centres. This thesis is based on interviews with seven youth-workers and managers within youth-centres in a large Swedish municipality. The aim of the study is to investigate how youth-workers and managers
In Sweden, what we eat accounts for about a third of the consumption-based greenhouse gas emissions, and there is strong evidence that the most effective way to reduce emissions is to switch to a more plant-based diet. A shift is currently underway in the Swedish food system; the market for plant-based products is showing an exponential growth, coupled with, for the first time since the 1950s, a d
The purpose of this study was to analyze how Retuna Återbruksgalleria by using Nudging, a behavioural theory, could operate as an environmental educator and attain a sustainable consumer which together could result in competitiveness on the market. Four different nudging tools was analyzed; simplification and framing of information, changes in the physical environment, the default option and the u
Due to the environmental impact of food waste and its implications on the economic performance of restaurants, the importance of reducing food waste has taken a central role in the management of restaurants. This paper examines the difficulties which arise in the restaurant industry in their efforts to reduce food waste. In addition the paper aims to answer the following questions: Is food waste p
The growing number of African Presidents on Twitter affirms that media, in all its forms, will always play a fundamental role in contemporary politics. Moreover, based on its face value, the presence of Presidents on Twitter could suggest that citizens are gaining unprecedented access to their president. But, this thesis contends that the newness of Twitter should not blind us into thinking that t
The engineers at Westinghouse Electric Company have developed a new nuclear fuel design called TRITON11™, which will be used in Boiling Water Reactors (BWR). This project has been to develop a test program and an assembly fixture for TRITON11™. The test program can not be fully presented in this repport due to confidentiality. The test program is for the first scoping test that will be performed o
Utsläppskraven för avloppsreningsverk (ARV) i Sverige uppdateras regelbundet, och samtidigt ökar även kraven på energieffektivitet. Vid Klagshamns avloppsreningsverk i södra Malmö har den inkommande kvävebelastningen ökat under en lång tid, och för att minska denna planeras separat rejektvattenbehandling med en anammoxprocess att implementeras på verket. VA SYD vill därför undersöka om processändr
The aim of this study is to investigate the implementation process of a political action in Malmö. The empirical case is a recently ended ”area-programme” in the city-district of Segevång that had as its main objective to social sustainability in the area. The study is based on theories of implementation such as the top-down and the bottom-up perspectives, the latter of which is exemplified with
Efterfrågan på nybyggnation och behovet av infrastruktursatsningar är en ständig och stor uppgift som kommuner och andra myndigheter arbetar med. Stora krav ställs på att samhällsplaneringen ska ske utifrån ett långsiktigt hållbart perspektiv. Att intensiva och omfattande regn har blivit allt vanligare på senare tid resulterar i att samhällsplaneringen måste anpassas därefter, och flödesanalyser oThe government and municipalities of Sweden are responsible for the huge task of meeting the need of constructional and infrastructural investments. While planning and managing the land they are required to do so with long term perspectives. As intense and voluminous downpours have become common lately, the city planning and land management have to be adapted to this, which leads to flow analyses
Introduction The aim of this study is to determine the locations for school construction in two isolated mountainous communities in Gorno-Badakhshan Autonomous Oblast (GBAO) – Khorog and Porshnev towns. In recent decades, this region has become increasingly vulnerable to natural disasters. A major contributing factor to this vulnerability is the fact that very little land is available for human se
A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was succes
