It is the turbine users who have requested a longer time in order to reduce maintenance costs and increase availability. Prior to the work, external and

Josefin Methi Sundell Miljönämndens inflytande som remissinstans i planärenden Hur kommunerna planerar områden i och kring våra städer, är viktigt för att göra användningen av mark- och vattenresurser hållbar på lång sikt. Därför har jag undersökt vilket inflytande Miljönämnden har haft när kommunala planer har tagits fram i Malmö, under de senaste sex åren. Stadsbyggnadskontoret tar fram planThis study reviews the influence of the Environment Board in municipal spatial planning in the city of Malmö and aims to highlight improvements in the consultation process. The municipalities are responsible for planning how land and water resources are to be used and thus central in attaining a sustainable land use and urban planning. Development plans are created by The City Planning Office and

Producing electrical power with photovoltaic solar panels is very attractive as the sun constitutes an inexhaustible source of clean energy. However, in order to make it a better alternative to other energy sources, its drawbacks must be addressed. In particular, scientific research is very active to find technologies that increase the efficiency of the solar cells, or decrease their cost. Reducin

Bröstcancer är den vanligaste cancerformen hos kvinnor i Sverige och står ensam för 30 % av cancerdiagnoserna. Detta innebär att varje dag får 20 kvinnor beskedet att de har drabbats av bröstcancer. Idag får ungefär 50 % av alla cancerpatienter strålbehandling och på strålbehandlingsavdelningen vid Skånes universitetssjukhus (SUS) behandlas flertalet bröstcancerpatienter dagligen. Vanligast är aBackground and purpose: Post-operative adjuvant radiotherapy of left-sided breast cancer patients is associated with cardiac and pulmonary complication. By utilizing different respiratory gating techniques the absorbed dose to the heart and lung can decrease. The purpose of this study was to evaluate and compare enhanced inspiration gating (EIG) and deep inspiration breath hold (DIBH). The use of

The information contained in the DNA (Deoxyribonucleic acid) of an organism that will finally be expressed, is first converted into a molecule called RNA (Ribonucleic acid). This is mainly composed of two types of sequences: the exons, carrying the information that will give rise to the formation of proteins and will be finally expressed in the organism, and the introns, which mainly include regul

Habenulas roll vid kronisk smärta Kronisk smärta är ett stort folkhälsoproblem som drabbar ca 20 % av den Europeiska befolkningen. Trots denna höga prevalens är rådande kunskap bristfälligt och modern forskning inom fältet har inte kunnat uppvisa några speciellt åtråvärda resultat. Detta beror delvis på den stora komplexiteten inom smärtfältet, där känslor och andra kognitiva aspekter är en integ

Elin Sandell Klimatanpassning, vad behöver vi veta? Fram till idag har arbetet med att klimatanpassa samhället främst varit inriktat på det offentliga Sverige. I syfte att nå ett samhälle som står robust inför klimatförändringarna måste fler aktörer bidra. Denna studie ämnar underlätta implementeringen av arbete med klimatanpassning på Riksbyggen genom att, bland medarbetarna, kartlägga befintliClimate changes are already affecting multiple levels of both private and public sectors. The rate of climate change adaptation must therefore be increased by efficient and intelligent efforts of all actors in society. This study maps the existing and required resources in terms of knowledge in the area of climate change adaptation of employees at Riksbyggen in order to facilitate their efforts to

Denna studie granskar det urbana hållbarhetsarbetet i Köpenhamn, nämligen deras ”Smart city”- strategi, med fokus på ett specifikt spårningsprojekt som staden startat. Några aspekter som tas upp är integritet, medborgardeltagande och transparens. Som en konsekvens av en ökande urbanisering står städer världen över inför flera urbana utmaningar som kräver att de förändrar hur de planerar och arbeCities around the world are facing a multitude of urban challenges that demand that they change the way they plan and think about their city, with one of the ways of approaching sustainability being the Smart city. A core feature of the Smart city is the idea of collecting large quantities of data on the city, big data, which is then used in various city solutions. In the wake of this, several que

Neoliberalism, as a loosely defined set of political beliefs, calls for more individual freedom and autonomy, resulting in increased responsibility for each person to address major societal issues. ‘Individualization’ is the process by which responsibility for addressing major environmental issues such as climate change is placed on individuals. In this thesis I investigate whether individualizati

Knowledge acquired through ecosystem service valuations can provide valuable information to stakeholders making land-use decisions. Effective use of ecosystem service valuation knowledge with a cost-benefit analysis can create resilient social-ecological systems. There is an increasing number of valuations being conducted, yet only one third of the studies are thought to be used in some form to ai

This thesis examines the integration of post-disaster recovery into urban renewal to foster a more sustainable district. The complex and multidimensional nature of post-disaster recovery necessitates a comprehensive understanding of various disciplines. Instead of focusing solely on physical reconstruction, this research seeks to enhance temporary living conditions by considering the entirety of t

At the very core of this thesis is the motivation to better understand how the seemingly inherent connection between powerful social agents and judges is produced and reproduced. The thesis also seeks to contribute to the view that who judges matters. This is not only true for the identity of the institutions they comprise, but for the individuals they adjudicate on behalf of. As a result, there e

Fördämningar hämmar insektsproduktionen i Rönne Å Under de senaste århundradena har vi människor fördämt, rätat ut, vallat in och grävt ner våra vattendrag för att anpassa dem för våra ständigt ökande behov av elektricitet, jordbruksmark och infrastruktur. Dessa åtgärder har emellertid lett till en förenkling och fragmentering av de utsatta vattendragen vilket resulterat i stora förluster av faunDam deconstruction has during the last decades proven to be a successful measure to re-establish fish migration and spawning in the upper reaches of rivers. In addition, an ample collection of literature has provided evidence that marine derived nutrients (MDN) released by anadromous fish serves as an important supplement for production, especially in oligotrophic rivers and riparian zones. An inc

Sannolikheten att det finns en högtalare nära dig är hög. De finns där för att spela musik i en affär, för att meddela att brandlarmet har gått i byggnaden du befinner dig i eller för att berätta att tåget du ska åka med är inställt. Alla högtalare låter på lite olika sätt, de har sina egna skavanker som gör att en viss frekvens kanske låter lite mer än andra. I detta projekt har vi funderat på deThis thesis investigates the performance and feasibility of passive and active analog frequency compensation filters for audio signal processing in a distributed speaker system. One passive and one active circuit topology were investigated more thoroughly and then the active filter was realized on a PCB and evaluated with electrical, thermal and acoustic measurements. The work also resulted in tw

The pulmonary route has emerged as a promising strategy for delivering protein therapeutics, particularly for patients suffering from respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), and pulmonary infections. This project investigated the effect of operating parameters of a laboratory spray dryer on the characteristics of powders composed of Bovine Serum Albumin

Sverige genomgår för tillfället strukturella förändringar i befolkningssammansättningen. Andelen äldre blir större och andelen yngre blir tvärtemot mindre. Denna demografiska utveckling får stora följder för samhället, inte minst för bostadsmarknaden. Människor i olika åldrar har olika boendepreferenser och när fördelningen i samhället förändras, förändras också behovet av olika typer av bostäder.Sweden is facing significant demographic changes, with declining birth rates and an ageing population that is not only growing older but also growing in number. These shifts affect many areas of society, particularly the housing market. Since people of different ages have different housing preferences, the demand for various types of housing is also changing. Against this background, this study ex

5-Hydroxymethylfurfural (HMF) is a versatile bio-based platform chemical that can substitute fossil-derived intermediates in polymers, solvents, and fuels, thereby contributing to a fossil-free chemical industry. While first-generation feedstocks such as high-fructose corn syrup have been widely studied, their use raises concerns about competition with food supply. In contrast, second-generation r

Purpose: The aim of the thesis is to create a prototype model for Time-Driven Activity-Based Costing (TD-ABC) within Lean Accounting, to study whether it can serve efficiently for cost and resource allocation within Skånes Universitetssjukhus (SUS) and compare TD-ABC with the existing costing method. Methodology: To deepen our understanding of the subject we have chosen to observe a health care p
