Sectarianism has emerged in the post-2011 era as an essential factor in the politics of the Middle East. It is not realistic to discuss the political unrest of the contemporary Middle East without discussing Sectarianism. Syria today suffers a violent sectarian war that threatens ramification that can be felt everywhere in the Middle East. This study focuses on the political elites that are involv

The purpose of the thesis is to explore customer expectations and experiences towards in-store applications and compare those in order to see if there are any gaps. The study is based on qualitative methodology and abductive research approach, enhancing the in-depth understanding of the phenomenon of the in-store applications. 14 semi-structured video interviews of 26-50 min duration were conducte

Alternative business models such as product-service systems (PSSs) have been cited as a solution for the impacts from consumption and fast fashion, but there is a lack of evidence supporting the environmental claims of such business models for clothing. The research aimed to understand if rental clothing business models such as PSSs have the environmental benefits often purported by identifying wa

This study is an exploratory qualitative case study that seeks to capture nuanced and personal perspectives on the experiences of the Tunisian democratization process. The aim of this study is to examine what the expectations of the regime change was and how these expectations relate to the perceived reality. In doing so, it utilizes a theoretical framework based on elements from the works of Seym

As Europe witnesses a rise in support of the far-right, more attention is being paid to why nationalistic sentiment is gaining popularity, particularly amongst rural populations. However, less known is how nationalism interacts with pressing ecological issues, even less so with agricultural matters. Given that a large proportion of farmers in the UK are said to have supported Brexit, it is importa

It is generally agreed upon that social trust is strongly associated with income inequality. However, this conclusion is mainly drawn from cross-country studies, which most likely suffer from endogeneity issues due to unobserved cultural, social and political variables affecting both trust and inequality. In this paper we collect trust data from six different surveys and make them comparable throu

Sustainability issues within the fashion market is frequently debated. Especially, whether fast fashion can be considered as sustainable. This bachelor thesis draws on the discussion about fast fashion and sustainability, and how different discourses is being reproduced within different media outlets. By comparing journalistic articles about fast fashion and sustainability from the news media outl

Here a lung-on-a-chip device was developed and fabricated using 3D-printing of molds. The lung-on-a-chip device was used as a lung injury model by overstretching of murine lung epithelial cells (MLE-12) monolayers, resembling the injury during mechanical ventilation. The cells were exposed to 25% strain, representing pathological conditions seen in ventilator induced lung injury of patients with

Insekter är en essentiell komponent i många ekosystem. Rollerna som de har är viktiga, vilka inkluderar spridning av växters frön, pollinering och att vara en källa till näring för andra djur. Dock finns aspekter med insekter som innebär hot för människor. Exempelvis kräver malaria cirka 400 000 människoliv per år, en sjukdom som förs vidare av myggor. För att kunna bekämpa sjukdomar som malaria Using laser it is possible to measure the backscattered light from insects. The resulting signal can then be analysed in order to potentially determine the species of the insect. Estimating the fundamental wing beat frequency (FWBF) of insects is important in order do this classification of species, which is an area of research that has been explored previously. In this thesis, the relative phase

In this study, the extraction and isolation of xylan from milled oat hull materials was investigated. Alkali extraction by 2 M sodium hydroxide at 40°C overnight was applied. The yield of extracted xylan was 5%. The extracted xylan was isolated from the extraction mixture by ethanol (99.9%) after neutralization and its purity was checked, resulting in a66% pure product. The semi-purified xylan was

For a city and culture that excels at adding value to waste, Kisumu struggles with a systematic approach for solid-waste management. Food and animal wastes run rampant in the streets while families still cook for hoursevery day using harmful fuels like kerosene, charcoal and firewood. This project takes to heart the insight that if a solution isn’t affordable to those who need it the most — it’s n

Momentvektorering uppnås genom att manipulera bilens hjulhastigheter, i syfte att öka kurvhastigheterna och förbättra trafiksäkerheten. En dubbelkoppling på bakaxeln är en möjlig vektoreringsmetod för en bakhjulsdriven Formula Student-bil. Dubbelkopplingen gör att det inre hjulet kan glida och därmed skapa ett vridmoment kring bilens kropp i kurvans färdriktning. Målet med examensarbetet var att Torque vectoring for automobiles is used to increase cornering speeds and improve road safety by manipulating the car's wheel-speeds. One method of torque vectoring for a rear-wheel-drive Formula Student race car is using a dual-clutch to slip the inner wheel thus create a yaw moment during cornering. The goal of this thesis was to develop and design an electronic control unit to automaticall

This essay follows the repatriation process and debate concerning the return of the Paracas textiles from the Museum of World Culture in Gothenburg, Sweden to the National Museum in Lima, Peru. The essay uses mass media such as newspaper articles and radio segments to map the themes and problems that arise when one country asks for the return of cultural artefacts and the other country has to resp

The present master thesis was performed in cooperation with the company “Aventure AB”. The company’s R&D department envisioned a new yoghurt-based product able to decrease the blood glucose levels after a meal. The innovative characteristic of the product is due to the diet fibers of the barley grain, which is going to be incorporated inside the yoghurt. The preliminary experiments which were

“Cultural identity is closely linked to their ancestral lands. If they are deprived of them, by means of forced displacement, it seriously affects their cultural identity, and finally, their very right to life lato sensu...” (Sawhoyamaxa Indigenous Community v. Paraguay) In the last five decades a movement calling for the protection of indigenous peoples’ rights has precipitated in a wave of inte

In vehicles there are many issues involving the safety and performance. The safety issues are often regulated by governments, whereas the performance by the customer. One solution to both these issues is to take use of an all-wheel drive system, where a coupling engages and disengages driving axles when needed. Such a solution will, through added traction and stability, increase performance and sa
