This work investigates how the heat produced by a solar dryer can improve the drying process of newly developed breathable membrane bags for drying and thus preserving fruits in developing countries and the increased efficiency of the process. For that purpose, a solar dryer was built and tested in an indoor solar simulator with similar irradiation as the sun. Due to a limited time span, only one

This essay will explore which social and cultural mechanisms that legitimatize a group of people to commit genocide by discussing the terms “victimization” and “de-humanization”. The essay starts with a research on the term “genocide”, specifically which groups that are, or are not, protected under the Genocide Convention and moves on to Stuart Kaufmans “symbolic politics theory” to discuss how po

Abstract: China’s development today no doubt has had the country placed in the centre of the stage. However, the past turns out to be the opposite if we look back. While the other major countries stepped into the industrial era it seems like China was still napping with its daydreams. In this paper we dig deeply into the political, economic and social aspects of the country at the time and we thin

The purpose of this study was to understand the relationship between poverty and crime, and what role poverty plays in relation to traditional crime from the perspective of ex-criminals. Eight semi-structured life story interviews were conducted in the southern county of Skane, with recently desisted and rehabilitated men. The age span was broad, ranging from 32 to 63 years of age. All interviewee

Från förbränning av industri- och hushållsavfall erhålls bland annat restprodukten slagg, vilket är bottenaskan från förbränningen. Varje år skapas stora volymer både i Sverige och i övriga Europa. Den naturliga processen karbonatisering, vilken involverar en reaktion mellan luftens koldioxid och kalcium i materialet, startar då slagg efter förbränning kommer i kontakt med luft. Karbonatiseringen From incineration of industrial- and household waste bottom ash is generated. A large volume of bottom ash is generated yearly in both Sweden and Europe. The natural carbonation process, which involves a reaction between carbon dioxide and calcium in the material, is initiated when the bottom ash reaches contact with air. The carbonation binds carbon dioxide to the bottom ash, decreases the pH and

This thesis examines the ejido system in Mexico in order to understand the dynamics of land tenure, governance and transaction costs through the lens of Elinor Ostrom’s theory of good governance. This case of the ejido system was chosen as their constitution that enabled a communal access land tenure regime in the agricultural sector, was amended to allow for privatization. The ejido serves as a p

This is an ethnographic study on how refugees and policies on asylum and immigration was debated on Facebook in Sweden during the so called ‘refugee crisis’. This study analysed the relation between the Facebook debate, and the way news media framed the ‘refugee crisis’ during three months in which Swedish asylum policy changed drastically: September 2015, November 2015 and January 2016. In Septem

Uppsatsens syfte är att undersöka maktrelationers påverkan vid kriser och samhällstörningar med särskilt fokus på hur detta framställs i utvärderingar av samhällets insatser vid kriser och samhällsstörningar. Det empiriska materialet består av två utvärderingar, dels utvärderingen efter skogsbranden i Västmanland 2014 (Sjökvist 2015) och dels utvärderingen efter helikopterrånet i Stockholm 2009 (R

Auralization is of interest in several disciplines - virtual reality, architecture and video games. Current trends in the eld of computuation have led to dramatic increases in performance in recent years. In this project, a prototype of an auralization-engine is developed. The program is capable of plausible room acoustic simulation in real time for a moving receiver and arbitrary room models. Thi

Vi har konstruerat en liten robot på hjul som kan köra runt i matbutiker och kartlägga positionen av prislappar. Roboten använder sig av kameror för att triangulera fram en 3D position för prislapparna som den har sett från flera vinklar. Roboten skapar automatiskt en karta över sin omgivning genom att optimera sin egen och omgivningens position för att minimera skillnaden mellan den matematiskt fThis report aims to compare methods that can be used to efficiently and accurately map digital price labels position in 3D space using a mobile robotic platform equipped with camera vision in a retail environment. The robotic platform built during the project uses four wide angle cameras to cover the full circular view in the horizontal plane. Installation of external systems for e.g. navigation c

This paper studies the possibility to exploit linear dependence in stock returns of the Swedish OMX 30 index. The main model studied in the paper is a Vector autoregressive (VAR) model. Ten years of data from the OMX 30 index is used, consisting of 27 stocks for the period 2006-2015 which is transformed into daily, weekly and monthly returns. First the significance of the models is tested and it i

The purpose of this study was to explore how relatives to addicts experience the relation between their own role, health and wellbeing and the support that they have received. It was based on semi-structured interviews with five persons who have or have had family members who are or were abusers of alcohol or drugs. The study used Antonovsky’s concept of Sense of Coherence as well as the notion of

According to dual-process models of recognition memory, an old/new recognition response can be based on a sense of familiarity and/or recollection of contextual details. Two topographically and functionally distinct ERP old/new effects are held as generic indices of familiarity and recollection respectively. However, episodic retrieval is believed to involve neural reactivation of content-specific

Denna uppsats behandlar idrottskvinnor i nyhetssändningar i svensk respektive italiensk public service-tv. Undersökningen redogör för hur kvinnliga idrottare skildras i jämförelse med manliga i nyhetssändningarna som granskats. För att skapa en internationell uppfattning vad gäller representationen av damidrotten i tv valdes en komparativ undersökning mellan Italiens och Sveriges public service-ka

The dawn of negative interest rates has drawn much attention to the German economist and libertarian socialist Silvio Gesell (1862-1930) who proposed the measure in the early 20th century. Although the attention has led to countless mentions in economic journal articles and speeches conducted by central bankers, often, no further effort is made of going deeper into his work. This paper intends to

Infrastruktur har länge ansetts tillhöra nyckelfaktorerna för ekonomiskt tillväxt. Dock saknas det i vetenskapen en uttalad konsensus gällande hur infrastruktur ska mätas och vilka mått som ska tillämpas i studier med syfte att studera infrastrukturens påverkan på tillväxten. Denna undersökning syftar till att studera den faktiska transporttid ett land uppvisar och studera om denna uppmätta tid ka

Syftet med denna uppsats är att få förståelse för hur medlemmar på nätdejtingsidor upplever att sökprocessen inom nätdejting påverkar möjligheterna att bygga en relation. I uppsatsen undersöks också hur det stora utbudet av potentiella partners påverkar valet av partner. Dessutom studeras hur den egna föreställningen om en person online relaterar till samma person offline, det vill säga i det verk

Mixed martial arts (MMA) is one of the fastest growing sports of our time. At the same time the sport receives a lot of criticism for its violent nature. This essay examines why and how MMA has gained popularity in contemporary Sweden. To answer these questions, it is important to look at the different actors within the field of MMA in Sweden, the fighter, the promoters and the spectators. I will

Trä och andra organiska material riskerar att angripas av mikrobiell påväxt under vissa temperatur- och fuktförhållanden. Mögel- och rötsvamp kan börja växa på trä om fukthalten är tillräckligt hög. Rötsvampar bryter ner träets olika beståndsdelar i olika utsträckning beroende på svamp- och trädart. Det som påverkar rötsvampars tillväxt är bland annat fukthalt, temperatur, pH-värde och syrehalt.
