In this work, six soil samples have been analyzed. The samples come from different sedimentary layers on Earth. They were previously studied with the objective to find the trace concentration of iridium, to correlate the increased concentrations of iridium with meteorite impacts that have occurred on Earth. In this work the samples are reanalyzed with the purpose to investigate which other trace e
This master’s thesis focuses on pedagogy and aspects of learning and remembering within guided museum tours for people with dementia. We explore in what way learning and remembering are focused on and triggered during those tours and with the help of which pedagogical means. Furthermore, we discuss what place these tours have within the museum as an institution. In order to examine our questions a
Recruitment of new individuals is essential for a population to survive and flourish and bladderwrack (Fucus vesiculosus) is on the decline in some parts of the Baltic Sea. The causes being multitude and complex, culminating to the loss of light penetration being the main culprit. As society moves forward, artificial submerged structures may serve as new footholds for a waning population as well a
Saturated laser-induced fluorescence (saturated LIF) has been the topic of some research, however mainly regarding laser diagnostic methods conducted on flames. A few papers have discussed saturated LIF with the purpose of producing saturation curves of different fluorescent elements. The utilised methods in these cases have involved manually increasing the laser intensity and detecting the fluore
Electromagnetic compatibility (EMC) is a crucial aspect to product development. Companies need to make sure their products live up to the standards that exists around the world. One way of reducing electromagnetic emissions is to shield the product, using some conducting material, for instance, copper. An issue arises, though, when transparency is needed, like it is for cameras. At Axis Communicat

This thesis investigates the effectiveness of a water mist fire suppression system in a submarine environment. As a first step in evaluating the viability of such a system aboard SAAB submarines, the water mist was simulated using an Eulerian-Lagrangian multi-phase model in the the commercial software Star CCM+. The CFD simulation results provide a good visualisation of the distribution of the mis
Nyligen har preliminär forskning funnit att personer med självskadebeteende och andra psykiatriska diagnoser verkar ha en lägre funktionsnivå avseende grundläggande självomhändertagande aktiviteter, jämfört med personer med psykiatriska diagnoser men utan självskadebeteende. Anledningarna till detta har dock inte studerats i tidigare forskning. En explorativ kvalitativ forskningsstudie med en kritRecently, preliminary research has suggested that people with deliberate self- harm (DSH) and other psychiatric disorders have a lower functioning regarding fundamental self-care activities, compared to people with psychiatric disorders but without DSH. However, the reasons for this have not been studied in previous research. An explorative qualitative research study with a critical realist approa
Ichthyosaurierna (fisködlorna) är en grupp marina reptiler som levde under mesozoikum. De är alla inkluderade i överordningen Ichthyopterygia som består av minst 36 släkten och 80 arter. De tidigaste formerna förekommer i sediment avsatta under etagen olenek i äldre trias (dvs. för ca 250 miljoner år sedan), och de sista fisködlorna dog ut under cenoman i slutet av krita, (dvs. för ca 90 miljoner Ichthyosaurs (‘fish lizards’) are a group of marine reptiles that lived during the Mesozoic Era. They are all included in the superorder Ichthyopterygia, which consists of at least 36 genera and 80 species. The earliest ichthyosaurs occur in sediments deposited during the Olenekian in the Early Triassic (about 250 million years ago), and the last forms became extinct during the Cenoman in the Late
Today, breast cancer is the leading cause of cancer related death in women. Early detection of breast cancer relapse presents increased treatment options and better control. Protein biomarkers from plasma are currently measured by state-of-the-art methods like ELISA, which require antibodies with high sensitivity and specificity. Developing such assays is laborious and time consuming. Thus, there
Bacteria can live in a surface attached community called biofilm, where microorganisms can multiply, grow and produce extracellular polymeric substances (EPS) and biofilm formation proceeds in different stages from attachment to a mature biofilm. In food industry, biofilms are a significant issue that can affect product quality and safety when biofilms are formed in the processing equipment. The
This field study was done to get an understanding of how the agricultural method called “structural liming” might affect soil organisms in a negative way. Soil organisms are crucial as they perform biological processes that improve good soil structure. This is important as it enables sustainable food production, today, and in the future. Structural liming is used on clay soils to improve soil stru
Lipase is one of the most useful enzymes in food industry, which can catalyze the hydrolysis and the synthesis of esters. However, the high cost due to the poor operation stability of lipase hinders the wide use of it. In present research, the stability of lipases in aqueous systems has been thoroughly studied, while research on lipases in non-aqueous systems is limited. In this work, the secondar
Local governments (LG) have been given a key role in the work of reducing greenhouse gas (GHG) emissions. To find the local drivers of GHG emission LG can develop an inventory that accounts for all the emissions associated with the municipality. A fundamental difference concerns whether the inventory accounts for the emissions that occur within the geographical boundaries or if emissions from good
Disease susceptibility mapping can produce risk maps showing predictive distribution of disease incidences. Hence, it is a useful tool for disease prevention. Data-driven approaches for disease susceptibility mapping model relationships and patterns from experience data. Therefore, using data-driven methods can facilitate a simple and direct approach towards disease susceptibility mapping. In th
Purpose: The purpose of this research is to do an investigation on the interlinkages between CEO compensation and the firm risk. It further intends to see in particular, whether the firm risk has been interlinked with components of compensation like CEO’s incentive/bonus and stock options. Theoretical framework: CEO compensation, Incentives programs, Stock option, Risk management, Principal agency
A technique to estimate fungal growth rates in field samples was tested in soil. The technique is based on the addition of C-14-acetate to a soil slurry and the subsequent uptake and incorporation of the labelled acetate into the fungus specific substance ergosterol by the fungi. The addition of fungal inhibitors decreased acetate incorporation rates, while bacterial inhibitors did not. Fungus-fre
Syftet med studien var att undersöka och få en fördjupad förståelse för hur internrekryterade chefer upplever att bli chef för tidigare arbetskamrater, och få en ökad insikt i de utmaningar som kan uppstå i samband med detta. Som metod användes en kvalitativ ansats varpå tio semistrukturerade intervjuer genomfördes. För att analysera intervjumaterialet användes tematisk analys, vilket resulterade The aim of the study was to examine and gain a more in-depth understanding of bosses’ experience regarding internal promotion and becoming the boss for previous work colleagues, as well as gaining more thorough insight regarding the challenges that may occur. A qualitative approach was used in this study, and ten semi-structured interviews were conducted. Thematic analysis was used to analyze the
In the last decades, Bose-Einstein Condensates (BECs) have been a research topic of great interest. In 2015, a new type of liquid was found - dilute self-bound BEC droplets that have orders of magnitude lower density than air. These droplets are not predicted by classical van der Waals theory, but are stabilised by quantum fluctuations. In this bachelor thesis, these droplets were numerically stud
The topic of financial inclusion has attracted attention from several researchers and policymakers in the recent years. However, there has been limited number of studies in the context of Vietnam, especially to explore the factors driving financial inclusion in the country. The thesis aims to investigate the determinants of financial inclusion in Vietnam with a focus on a special group: the remitt
