Porous carbon obtained from low cost and abundant biomass has gained attention as renewable material feedstock. In this study, porous carbon biochar produced through pyrolysis was investigated by Raman spectroscopy to disclose the structural properties. The measured samples were in form of pellets (identified as WP, 139, 233, 226), and lumber wood (Pine, a softwood type and Beech, a hardwood type)

Latin American countries are among the happiest countries world-wide despite suffering from vast economic inequality at the same time. Addressing this alleged puzzle, this study analyses the effects of economic prosperity and inequality on happiness in Latin America. Using a pooled dataset of annual surveys from the Latinobarómetro between 2005 and 2018, an advanced three-level model with individu

Thesis Purpose: The purpose of this study is to examine eco-label knowledge and eco-label trust, and their relationships to planned sustainable behaviour. This will be done by investigating the Swedish market and more specifically eco-labelled food within the FMCG sector. Methodology: This thesis adopted a deductive research approach which follows a quantitative research method. The data was coll

Detta examensarbete undersöker möjligheterna att implementera magneter för flera funktioner i en så kallad ”knob”. Projektet utfördes i samarbete med Sigma Connectivity. Under ett tidigare projekt på Sigma Connectivity uppstod ett intresse för att använda magneter i en av deras produkter. Denna produkt används för att välja alternativ genom att rotera en yttre part eller trycka på knappar på toppThis master thesis investigates the possibilities of implementing magnets for several functions in a knob. The project was carried out in collaboration with Sigma Connectivity. During a previous project at Sigma Connectivity, there occurred an interest in using mag-nets in a product called ”the knob”. This product is used to select options by swiveling an outer part or pushing buttons at the top.

African exports that end up in other African countries today is less than 20%, a low value compared to that of Europe, Asia and America, all above 50%. However, these intra-African exports are more diversified than African exports reaching other continents. Specifically, it is comprised of higher quality goods that stimulate stronger and more stable economic growth. To capitalize on this, various

The Swedish legal system has been under heavy criticism for its use and regulation of pre-trial detention since the beginning of the 90’s. The CPT and the CAT have been engaged in the issue, urging Swedish authorities to take action to address the critical conditions. Despite this, the conditions for pre-trial detention in Sweden appear unaltered. The Swedish legal system’s response to the heavy c

Recent phenomena, as the offshoring of R&D activities, have raised the question of whether intensive internationalization strategies are hampering the abilities of firms to implement innovations. This research wants to study the intensive margin of internationalization in order to understand whether the breakage of the links within the production processes, due to practices such as offshoring

In this study, a risk assessment has been carried out at a closed fire station and a closed mechanical workshop in the Swedish municipality of Eslöv. The aim of this study is to investigate whether the activities at the sites may have caused pollution and assess how big a risk they pose to human health and the environment. The method being used to evaluate the risk is Method of Surveying Contamina

Climate change is affecting societies all over the world. Cities are especially vulnerable to climate change due to their particular features such as high proportion of hard surfaces, high interconnectedness between systems and lack of protection from natural ecosystems. The urban planning processes suit well for implementing climate change adaptation (CCA) measures to protect the cities from the

The majority of plastic packaging is not being recycled today, but burned for energy recovery or sent to landfill. This leads to vast losses of recyclable material, as well as elevated emissions of greenhouse gases from the extraction of fossil oil needed to sustain the production of new plastics. To be able take effective measures to increase recycling, causes of the low recycling levels first ha

Studiens syfte undersöker hur kommunikationen, mellan medarbetare och chef inom restaurang- och cafébranschen, kan bidra till ett hälsofrämjande arbetsklimat. Detta görs genom en kvalitativ undersökningsmetod med fyra semistrukturerade intervjuer och två strukturerade elektroniska intervjuer på två olika arbetsplatser, för att undersöka deltagarnas upplevelser om kommunikationen som rör ämnet orgaThe aim of this study explores how communication, between coworkers and managers in the restaurant and café business, can contribute to a health-promoting work climate. This is done by a qualitative method including four semi-structured interviews and two structured electronic interviews, on two different workplaces, to examine the participants’ experiences about the communication on the topic org

The recent virus COVID-19 has forced companies around the world to change the way they work. Teams who usually work together in the same physical space are now experiencing working virtually from home. Previous studies demonstrate the importance of psychological safety and trust in the aim of building high-performing and effective teams. A virtual setting implies new challenges and opportunities f

Knowledge inequalities persist between the Global North and the Global South, but also within countries between privileged and underprivileged segments of society. The purpose of this study is to understand the motives of researchers from basic science and technology to investigate on socially demanded issues as well as the obstacles they encounter. The study is based on the experiences from eleve

Market and policy pressures increasingly demand a shift towards sustainable means of production; thereby, the inconclusive and long-standing debate between the impact of environmental efforts and economic performance at the firm level has never been so relevant. However, companies who seek to prioritize sustainability on their processes and outputs still need to focus on their financial returns.

Denna studie syftar till att undersöka hur lärande för hållbar utveckling (LHU) kan implementeras på arbetsplatsen. Detta med bakgrund i att vi idag genomgår en klimatkris och att det krävs en total omställning av samhällets alla sektorer för att hålla den globala temperaturökningen under 1.5 grader. Uppsatsen syftar till att synliggöra vikten av att LHU blir ett systematisk inslag på arbetsplatse

Studien är en kvalitativ undersökning av de incitament som ligger bakom människors beslut om att delta i vuxenutbildning. Vid genomförandet av studien har det utgåtts ifrån en hermeneutisk metodologi. Fyra semistrukturerade intervjuer utgör uppsatsens empiriska material. Urvalet av intervjupersoner sammanstod av två män och två kvinnor som har utexaminerats med högskolekompetens från Háskólabrú Ke

Introduction: This study attempts to optimize the choice of stationary phase for the separation of lignosulfonate lignin compounds using supercritical fluid chromatography coupled to mass spectrometry. Background: Lignin is a potential renewable source of phenolic compounds. Lignosulfonate lignins are produced during pulping processes producing very complex mixtures, which are challenging to anal

This thesis engages with the motherwork of racialised migrant mothers in Sweden’s racialised suburbs. It employs theories of racial geographies, particularly black women’s geographies and motherwork to investigate the articulations of motherwork in space. Deploying a black feminist lens on empirical material from a Swedish-Somali mothers’ group engaged in community activism, the thesis argues that

Cykeln har blivit ett allt vanligare transportmedel i Sverige. Som en följd av detta kommer nya lösningar och metoder krävas för att cykeln ska kunna ersätta bilen, exempelvis som vid till transport av husdjur.
