BACKGROUND: One of the major environmental threats to human health is air pollution. It contributes to premature deaths of millions of people worldwide. Air quality issues are growing exponentially in developing countries (West et al. 2016). More specifically, household air pollution that results from indoor cooking with solid fuels is damaging to the human health in LMIC. About 54% of global popu
This research aimed to explore the experiences of Lagos State residents during COVID-19 and the relationship between COVID-19 reportage in Lagos State and ethnic inter-relationship. The goal is to understand media influence in a society from the perspectives of people directly influenced by the COVID-19 media frames. This thesis is the first research to explore ethnic polarization in Lagos State w
The steel industry in Sweden is responsible for 10% of the annual Swedish CO2 emissions. As a way to abate this sector, H2 Green Steel are establishing a new green steel production site in Boden. Their way of producing steel, through the EAF route and by using hydrogen-reduced DRI will reduce the CO2 emissions by over 90%. Besides iron ore, steel scrap is the most important input raw material for
Barnäktenskap är ett fenomen som är vanligt förekommande i stora delar av världen. År 2004 infördes lagbestämmelser om att utländska barnäktenskap inte ska erkännas i Sverige om minst en av parterna haft anknytning till Sverige. För att stärka skyddet mot barnäktenskap skärptes lagen ytterligare år 2014. Under år 2018 lade regeringen fram ett förslag till ny lag om att förbjuda erkännandet av utläChild marriage is a phenomenon existing in many parts of the world. In 2004 a new law came into force stating that Sweden does not recognize foreign child marriages if at least one of the parts has ties to Sweden. In order to achieve an increased protection against child marriage the legislation was further strengthened in 2014. In 2018 the Swedish government presented a proposition to a new law f
This thesis consists of the development of a concept for a new product, the primary purpose of which is to quickly and easily attach legally required tags to the ears of livestock pigs. The project was undertaken at Attention, a product development company based in Copenhagen. For reasons of food safety, EU regulation stipulates that all pigs that are moved from their place of birth must be tagged
The digitalization of social work in Sweden has skyrocketed in the 21st century. New challenges are rising for social workers as well as social service users. The aim of this study was to explore school counselors' experiences conducting their counseling sessions online. This to find out what hardships they have encountered and how they dealt with them. The aim of this study was to contact gym
This master thesis investigates how to perform irrational decimation, the process of reducing the sample rate of a signal, for high throughput systems. The thesis work consists both an algorithmic part and an implementation part. In the algorithmic part, an algorithm that could cope with the requirements is found, and investigated due to different aspects. A group of filters that are investigate
Sammanfattning Denna uppsats undersöker sambandet mellan polisens utredningsåtgärder och personuppklaring och lagföring vid hedersrelaterad brottslighet. Det övergripande syftet är att redogöra för vilken betydelse rätt kunskap, förstahandsåtgärder och utredningsmetodik spelar för den fortsatta lagföringen. Jag vill också undersöka om den kunskapssatsning som gjorts av regeringen och rikspolisstyrThis thesis investigates the connection between police investigative measures, solved crimes and prosecution concerning honour related crime. The overall aim is to account for what significance correct knowledge, first measures taken and methods used during the investigation have for the following prosecution. I also wish to investigate whether the augmentation of knowledge initiated by the govern
Sammanfattning Surrogatmoderskap är inte är tillåtet i Sverige och har på senare tid blivit en mycket omdebatterad och högst aktuell fråga. Till följd av förändrade uppfattningar och föreställningar i samhället utreds nu huruvida surrogatmoderskap kan införas som en metod för att avhjälpa ofrivillig barnlöshet. En viktig aspekt på området är att hänsyn måste tas till det blivande barnet. BedömningSummary In Sweden gestational surrogacy is not allowed and has recently become a very controversial and highly topical issue. Due the changing perceptions and beliefs in society, it is now being investigated whether surrogacy can be introduced as a method to overcome involuntary childlessness. An important aspect of consideration must be to the prospective child. In assessing if gestational surrog
In mining for extraction of metals residues are often produced. A frequently produced residue is tailings, which potentially contains high amount of metals, soluble salts and acids. Therefore, it is often necessary to deposit, the tailings in stable impoundments, namely tailings dams, if not all tailings produced is used as backfill in mines. In the construction of the tailings dam in Garpenberg,
In Sweden the installed wind power has increased rapidly in recent years and the trend looks to continue. New law, in which Svenska Kraftnät will lend investment capital for expansion of grid capacity to renewable energy, will facilitate the connection of wind power plants to E.ON’s regional grid network. With more wind power connected to the grid network losses will look different.In this report,
Zabrze is a medium size town of 200 000 inhabitants in the region of Upper Silesia, Poland. The development of the town was originally based on the exploitation of heavy industries. In the past few years Zabrze has, however, moved towards more service and tourism oriented industries. As part of this journey, the city of Zabrze sees the need to improve its existing waste management system. This rep
Emerging infectious diseases (EID) continue to threaten the persistence of wildlife populations. The standing genetic variation of a population can affect its ability to adapt to environmental changes like EID. Levels of variation at immune genes, such as toll-like receptor genes (TLR) of the innate immune system, are particularly relevant. The current study explores the role of demographic histor
Charities play an essential role in Irish society. People benefit from support in health and social services, from social housing to specific health related organisations. It is important for charities to be able to invest in digital strategies which can support them in spreading the word of their cause, in raising awareness, in fundraising, and in recruiting talent. Importantly, digital strategie
The grain growth of WC in WC-7%Co cemented carbides with Cr-addition was investigated for cemented carbides synthesized from four different raw materials varying in grain size. Cr additions were 4%of the Co binder phase. To investigate the effect of Cr on grain growth two of the raw materials were also synthesized without Cr-additions. To investigate the effect of cobalt content on grain growth ce
Slow light and Whispering Gallery Mode Resonators are two interesting and useful fields with applications in optical sensing and laser stabilisation among others. Slow light can lead to long interaction times which are useful in light-matter interactions such as sensitive non-linear optics. Whispering Gallery Mode Resonators have small mode volumes and strong beam confinement leading to high Quali
Background: An extensive literature review pointed out the limited knowledge on the value of sustainability transparency in road freight distribution. This is researched in the context of non-compliance to current sustainability issues in Sweden. Additionally, the value of sustainability transparency for the procurement activity of a transport buyer was not explored. Purpose: The purpose of this s
Molten salt applications are challenging from a material perspective. This degree project was carried out at Alfa Laval to give them a better understanding of the corrosion of solar salt on the standard heat exchanger material stainless steel 321. Similar tests have previously been performed externally. By developing test methods for in-house corrosion testing time and money can be saved. In thi
In this master thesis computational fluid dynamic simulations of two plate heat exchanger channels have been performed in Ansys CFX. The full geometry of the channels has not been included, the channels were modeled with a flat geometry instead of a corrugated pattern. To account for the effect of the corrugation on the pressure drop, one-time pressure losses and momentum sources were added in the
