The purpose is to supply drinking water with good quality to the consumers. Groundwater is pumped from wells in Ignaberga and Tyringe and re- infiltrated into the glaciofluvial deposit. The aim with this thesis is to examine retention and dispersion of the re- infiltrat

War-inflicted violence affects civilians in a larger proportion than combattants - where the majority of the victims are women and children. It is also men, who often are the planners of war, whom at the same time are expected to be the constructors of peace, where women and gender issues are neglected. In this essay we will challenge traditional assumptions about peace and security by adopting a

The primary focus on this thesis is to investigate different actors attitudes on sustainable forestry and opportunities and restrictions experienced with these. The actors already manage forest in some way, or are interested in managing forest sustainable. Sustainable development was defined during the WCED in 1987 and has since then been a concept for planning. The concept sustainable development

Föroreningar från metallurgiska processer som sprids genom skorstenar och ventilationssystem är ett välkänt problem inom metallurgisk industri. På senare tid har även spridning av föroreningar i form av damm uppmärksammats som ett problem. Föroreningarna uppstår troligen från diffusa källor, vilket innebär att de inte kan härledas till en specifik punktkälla. Detta arbete uppstod som en följd av aPollution in the metallurgical industry has been a well-known problem in terms of dispersal through stacks and ventilation systems. In recent times attention has been drawn to fugitive dust emissions as a pollution problem. This paper aims to illustrate important aspects to develop a method to control dust emissions. The method of this report consisted of a literature and an interview study. The r

This work relates to the proposed n-nbar experiment at ESS and covers a procedure with which future neutron research can be made using a small TPC prototype. Settings for the GEM amplification voltage supply and main drift field across the chamber have been established using minimum ionizing cosmic muons as a reference. To be able to reconstruct tracks in three dimensions and measure the deposited

The aim of this study was to examine businesses which use horses in various kinds of social work, and the opinions and experiences of the professional practitioners of these operations. I used semistructured interview to answer my questions, and I ended up interviewing eight people from seven different operations. Everyone was working in some kind of business which used horses as either an aid for

Metod: En kvalitativ studie med ett hermeneutiskt fenomenologisk förhållningssätt har genomförts. Forskningsansatsen är deduktiv med induktiva inslag. PrPurpose: The aim is to qualitatively distinguish and understand differences in purchase behavior and loyalty, related to service, between Generation Y and Baby Boomers and thus contribute to the service and generational research. Methodology: A qualitative study has been executed with a hermeneutic phenomenological approach. The research approach is deductive while also containing inductive eleme

The main goal of this project was to use the Modelica features on embedded systems, real-time systems and basic mechanical modeling for the control of a two-wheeled self-balancing personal vehicle. The Elektor Wheelie, a Segway-like vehicle, was selected as the process to control. Modelica is an object-oriented language aimed at modeling of complex systems. The work in the thesis used the Modelica

With global warming and increased uncertainty about future vehicle fuel supply, the need for fuel efficient vehicles is growing. In this Master Thesis, design and implementation of a control strategy for fuel efficient deceleration is presented. The resulting deceleration controller, implemented in Embedded Matlab and Simulink, provides autonomous deceleration functionality to a vehicle cruise con

The DARPA Grand Challenge (DGC) 2005 was a competition, in form of a desert race for autonomous ground vehicles, arranged by the U.S. Defense Advanced Research Project Agency (DARPA). The purpose was to encourage research and development of related technology. The objective of the race was to track a distance of 131.6 miles in less than 10 hours without any human interaction. Only public GPS signa

This thesis investigates a new type of Phase-Locked Loop (PLL) architecture which combines a phase/frequency detector (PFD) and a digital loop filter. The quantization is done by a time-to-digital converter which continuously shrinks the pulse coming from the PFD and registers how far it propagates. Based on how far into the TDC each pulse propagates, the phase error is determined. The design is f

Bakgrund: Barn ska få vara delaktiga och få anpassat stöd för att uttrycka sig i sin intervention. Barn med autismspektrumdiagnos (ASD) har ofta en annorlunda sensorisk process, vilket kan påverka delaktighet i aktiviteter. Det saknas information kring hur arbetsterapeuter samkonstruerar med barnet som klient i interventioner. Syfte: Att undersöka hur arbetsterapeuters samkonstruktion sker med barBackground: Children must receive tailored support to participate and express themselves in their care. Children with autism spectrum disorder (ASD) commonly have a different sensory process, which can affect participation in activities. There is a lack of information regarding how occupational therapists collaborate with children as clients in interventions. Purpose: To investigate how occupation

Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. Reducing these substantial emissions aligns with the objectives of

Sveriges geologiska undersökning (SGU) har ägnat flera år åt att undersöka den svenska berggrunden för att utreda möjligheterna för geologisk lagring av koldioxid. Djupt liggande akviferer anses ha störst potential och den kambriska Faluddensandstenen, som finns i Östersjön öster om Gotland, visar stor potential som lagringsakvifer. I denna studie har borrkärnan St. Sutarve-2018 från södra GotlandThe Geological Survey of Sweden (SGU) has spent several years investigating the Swedish bedrock to find suitable bedrock for geological storage of carbon dioxide. Deep saline aquifers are considered to have the greatest potential, and the Cambrian Faludden Sandstone subcropping in the Baltic Sea east of Gotland, shows great potential as a storage aquifer. In this study, the drill core St. Sutarve

Today, the textile industry in Sweden is responsible for up to 1800 tons of textile waste per year, a poor use of resources that results in a negative environmental impact. Additionally, with the rise of fast fashion, which is characterized by rapid trend circulation and a clothing production that matches, clothes are discarded at a higher rate than ever before. However, the popularity of secondha

During the past ten years, Sweden's security policy has undergone a clear change, where key events have been Russia's invasion of Ukraine in 2022 and, most recently, Sweden's entry into NATO in 2024. The focus on issues such as national security and military rearmament have increased. The essay discusses how a perceived need to improve resilience has put requirements on the population

This thesis studied the recording methodologies of conducting unannounced evacuation drills to enhance the understanding of evacuation behaviours and performance within the Complex Muon Solenoid (CMS) cavern at CERN. The primary objective was to validate the CMS underground evacuation simulation model for planned evacuation and compare various data collection methods. An unannounced evacuation dr

Preeclampsia (PE) occurs in up to 5% of worldwide pregnancies. It is a complex disease characterised by sudden onset hypertension, and it is harmful to the mother as well as the growing baby, accounting for 40% of fetal deaths worldwide. The disease can be divided into early and late-onset PE, defined as diagnosis earlier or later than 34 weeks of gestation. Despite decades of research, the cause
