I det morderna samhället spelar appar en central roll. Detta gäller även på Assa Abloy Entrance Systems, där appar används av tekniker för att installera, underhålla och reparera automatiska dörrar. Just nu utvecklas en app som kommer att ersätta alla nuvarande appar. Bakgrunden till detta examensarbete var att involvera framtida användare i utvecklingsprocessen med målet att förbättra användbApps are a central part of modern society, including technicians at Assa Abloy Entrance systems. They use several apps for installing, maintaining and repairing automatic doors. A new app is currently in development to replace all existing apps. The background of this master’s thesis project was to involve future users in the development process with the aim to enhance usability and work satisfac

In this study, the internal load of phosphorus in Lake Vomb is explored. Years of external inputs from untreated sewage and agricultural runoff have built up tonnes of phosphorus in the lake sediment, periodically released causing HABs and impairing water quality. The aim of this study is to investigate how the internal load varies over a year and to explore correlations between internal loading,

This study aimed to explore how individuals with experience of homelessness perceived the available support services, as well as how they experienced their encounters with social workers, highlighting effective current practices and identifying areas needing improvement. Based on narrative interviews with six formerly homeless individuals in Stockholm, Sweden, their experiences were analysed using

Bygg- och fastighetssektorn står för en avsevärd del av Sveriges klimatpåverkan och resursanvändning, där stålproduktionen är en betydande faktor. Trots att stål är ett material med hög återvinningsgrad är direktåterbruket av bärande stålkomponenter i dagsläget begränsat. Detta utgör en outnyttjad potential för att minska koldioxidutsläpp och främja en cirkulär ekonomi, där Design för Demontering The construction and real estate sector accounts for a considerable share of Sweden's climate impact and resource use, with steel production being a significant factor. Although steel is a material with a high recycling rate, the direct reuse of load-bearing steel components is currently limited. This represents an untapped potential for reducing carbon dioxide emissions and promoting a circul

Julius Tröger first synthesised ‘C17H18N2’ as an unknown product from the condensation of anilines with formaldehyde. From that point on, the history of Tröger’s base (TB) has widely evolved as new applications for its characteristic rigid, chiral framework easy to functionalise. It is in the field of supramolecular chemistry that TB has gathered the most attention these last years. This work is f

This thesis investigates the relationship between Protestant and Catholic religious affiliation and union outcomes, as well as religiosity and union outcomes in Northern Ireland. I conduct a multinomial logistic regression analysis using pooled cross-sectional data from the Northern Ireland Life and Times survey from 1998–2023. I find that cohabitation has increased in the 21st century, and that r

Denna kandidatuppsats undersöker hur användare uppfattar så kallade ”deceptive patterns” - vilseledande designmönster - i digitala användargränssnitt, samt var gränsen går mellan påverkan och manipulation. Studien kombinerar en kvantitativ enkätundersökning med en kvalitativ intervjustudie för att fånga både bredd och djup i ämnet. Enkäten, som riktades till svenska internetanvändare, inkluderade

History leaves its marks on the life of a city. As urban landscapes continue to expand and evolve, old industrial sites and urban functions are often left behind, fading into the margins of the contemporary city. This thesis seeks to explore how architecture and public space can breathe new life into these forgotten areas, reactivating them as meaningful parts of the city’s present and future.The

Inhalation of engineered nanoparticles that are handled as powders or sprays in consumer products poses a potential health risk. To investigate the effects of nanoparticles on human health, the Nano Aerosol Chamber for In-Vitro Toxicity (NACIVT) system has been designed for controlled deposition of aerosol particles onto cell cultures. The objective of this study was to estimate the deposited dose

Galectins are proteins that bind to carbohydrate structures, with high affinity for β-galactoside ligands that exists naturally in our bodies. They are involved in the development of various diseases, including central nervous system diseases and cancer proliferation. Galectin-1, which is the focus in this thesis, is related to anti-inflammatory and neuroprotective functions in the brain. Drug del

Sociala medier har med tiden utvecklats från att vara en plattform för kommunikation och socialisering, till att även möjliggöra shopping och tillfredsställa olika konsumtionsbegär. Genom social commerce, FOMO, impulsköp och UGC påverkas konsumenterna ständigt till att konsumera mer än vad de gjort tidigare. Sociala medier har blivit en marknadsföringsplats för många företag och har utvecklats til

Kraftvärmeverk producerar el, och levererar värme till fjärrvärmenätet. Nätets returflöde till dessa verk har generellt en relativt hög temperatur, och det finns idag verksamheter som använder sig av denna returvärme för att värma upp anläggningar och utrymmen som har värmebehov. Det finns en potential att på liknande sätt utnyttja denna för uppvärmning av växthus, vilket utgör en synergimöjlighetCogeneration plants generate electricity and supply heat to the district heating network. The return flow from the network to these plants generally has a relatively high temperature, and there are currently operations that utilize this return heat to warm facilities and spaces with heating needs. There is potential to similarly use this return heat for greenhouse heating, which presents a synergy

Textile recycling is highly needed as great amounts of waste are produced every year and most of it is put into landfill or incinerated. This thesis lays the foundations for a quality control system which may be applied for controlling the recycling of cellulosic textiles in an upcoming pilot plant based on ShareTex’s technology. The quality control system was constructed as a mathematical model r

Disparities in health is a common issue in society, with people of different socioeconomic backgrounds having different possibilities in terms of achieving a good level of health. Stress is a common result of this, followed by insomnia and sleep impairment amongst those who are at a socioeconomic disadvantage. In this study, data was collected from multiple Swedish databases to explore whether sle

Tropiska skogar utsätts för mer intensiva och frekventa torkor. Torkor påverkar tillväxt och kollagring i skogen, samt ökar risken för trädödlighet. Det finns flera hypoteser om mekanismerna bakom dödlighet under torka. Två av de vanligaste är något som kallas kolsvält och kavitation. Det är oklart vilken av dessa två mekanismer som inträffar först i tropiska träd under långvarig torka. ExperimentTropical forests experience more intense and frequent droughts. Droughts affect mortality in trees, growth rate and carbon storage in the forest. There are several hypotheses of the mechanisms behind tree mortality during drought. Two of the most common ones are carbon starvation and hydraulic failure. It is unclear which of these mechanisms occur first in tropical trees during long term drought.

Battery energy storage systems (BESS) are becoming increasingly important for storing energy, particularly renewable energy, and stabilizing electricity grids. These systems often use lithium-ion batteries, which are efficient but pose risks during accidents. Rapid implementation of BESS has led to uncertainties in regulations and emergency response protocols. This thesis aims to identify and eval

Radar has come a long way since its invention in the 1930s. It is not only used to detect the distance and angular position of a target but can also measure velocity thanks to the Doppler frequency shift. In more advanced systems, the radar can perform tasks such as imaging and classification of the target. In some cases, full or partial polarimetry is used to gain additional information about the

The growing demand for the recognition of sexual and reproductive rights as a fundamental part of human rights by the approval of policies that make access to them a reality has been classified as one of the factors fueling political polarization, a phenomenon that seems to be transforming global politics, and which was consolidated in the Peruvian context after the 2021 elections. In the middle o
