This master thesis project was performed in collaboration with Johnson Matthey. Johnson Matthey is a worldwide company working with sustainable technologies. The site in Perstorp, where this work was performed, focus on formaldehyde production. In order to continuously improve chemical processes, simulation and modeling are advantageous tools. They can give a better understanding of the processes
Villa homes are designed to be able to tackle many injured leading factors. Today's villa homes are planned and projected by many years of experience in villa construction. No matter how well you planned the project planning and execute it, an injury can occur. Moisture and water damage can occur from a variety of factors, both from the outer- and inner factors. The external factors may be in
Gambro is one of the biggest developers and manufactures of machines for hemodialysis treatments in the world. One component on their machines, the air level detector (ALD), has been identified to have a possibility to be further improved from usability perspective. The ALD is located at the front of the machine and has the function to hold the venous drip chamber in place and detect whether or no
The critics about poor performance of NGOs over the last two decades focuses on their inclination towards ‘big D’ development – project based intentional activity in health, education and water which has little intention to challenge existing power relation and social structures - and underlined the loss of transformatory edge of participation. Critics further urged NGOs to realign their orientati
I slutet av 2010 upplopp i Tunisien ledde till att den Ben Ali regimen som hade styrt Tunisien sedan 1987 föll. Efter regimens fall gjordes efterfrågningar, till stor del från civilsamhället, angående hur man skulle hantera det förflutna i form av en process av övergångsrättvisa (transitional justice). I december 2013 antogs en lag om övergångsrättvisa. Lagen definierade perioden som skulle ingå iIn the end 2010 uprisings in Tunisia led to the fall of the regime of Ben Ali who had governed Tunisia since 1987. After the fall of the government request regarding how to handle the past in form of a transitional justice process was made, mainly from civil society. In December 2013 a law on transitional justice was adopted that defines the period that the transitional justice process is aiming o

1. In a correlative study, we investigated the relative importance of fish predation, refuge availability and resource supply in determining the abundance and size distributions of the introduced and omnivorous signal crayfish (Pacifastacus leniusculus) in lakes and streams. Moreover, the biomass and food selection of predatory fish was estimated in each habitat type and stable isotopes of carbon
Popular Abstract in Swedish En omorganisation av det svenska Vägverket har medfört ett behov för dem att fungera som en professionell beställare enbart, utan utförande i egen regi. Det har naturligtvis också medfört en förändring i hur man hanterar upphandlingen av vägunderhåll. En väghållares främsta uppgift är att underhålla befintliga anläggningar och se till at de fungerar som avsett. Den näsA reorganization of the Swedish National Road Administration (SNRA) has urged a demand to work as a professional agency only, without any work by direct labor. This structure has enforced a change in how to handle the pavement maintenance and performance contracts are being promoted since they encourage product development and sustainability. Furthermore, SNRA desires to use the road network as a
Popular Abstract in Swedish I en komponent som utsätts för upprepande på- och avlastningar, d.v.s. cyklisk belastning, kan defekter i form av sprickor initieras och börja växa. Detta fenomen kallas utmattning och kan leda till haveri med potentiellt katastrofala följder. Det är därför viktigt att förstå fenomenen som ligger bakom utmattning och att ha tillförlitliga modeller för att förutsäga livsUnderstanding of the growth of fatigue cracks is of utmost importance since such growth often has a profound influence on the life of components subjected to cyclic loading. Thus, reliable fatigue life models enable a more efficient use of materials and improve the performance and efficiency in many applications. This thesis deals with the growth of fatigue cracks subjected to high load amplitude
Popular Abstract in Swedish Aneurysm är ett sjukdomstillstånd som är känt sedan ca 2000 år före vår tideräkning, och bukaortaaneurysm (bråck på stora kroppspulsådern i buken) beskrivs i publikationer från 1500-talet. På 1800-talet försökte man sig på att behandla med ligering, tyvärr med dåligt resultat, och först på 1920-talet beskrivs den första lyckade ligeringen. Behandling med graftrekonstrukThe incidence of abdominal aortic aneurysms (AAA) is increasing. The risk of rupture is related to diameter. However, rupture may occur also in small AAA. To evaluate the size of an aneurysm when related to the predicted normal aortic diameter might be a better predictor of risk. AAA:s, range 40-55 mm were studied in relation to gender. No difference in AAA diameter was found. However, body surfac
Popular Abstract in Swedish Klorofyllsyntes är en viktig process i naturen. De gröna pigmenten utgör en viktig del i fotosyntesen där de absorberar och överför solenergi till fotosyntetiska reaktionscentra. Magnesium kelatas katalyserar insättandet av en magnesium (II) jon i protoporfyrin IX, vilket är det första specifika steget i klorofyllsyntesen. Magnesium kelatas består av tre proteiner, som The biosynthesis of chlorophylls is an important process in nature. The green pigments play a fundamental role in absorbing and transferring solar energy to the photosynthetic apparatus. This thesis elucidates the role and function of the enzyme magnesium chelatase, which catalyses the insertion of magnesium (II) into protoporphyrin IX and is the first committed enzyme of the chlorophyll biosynthe
Tidigare forskning om samverkan visar att samarbete innefattar problem och konflikter. Syftet med denna studie är att istället beskriva mer framgångsrik samverkan även om denna utspelas under kortare interaktionsfrekvenser. I boken diskuteras forskning som analyserat framgångsfaktorer men framförallt analyseras ett eget empiriskt material med fokus på hur och när aktörerna inom ungdomsvården framsPrevious collaboration research shows that problems and conflicts sometimes arise as a part of collaboration. This book analyzes successful cooperation unfolding during shorter interaction sequences. In this study I endeavour to describe the contributing factors that are necessary to achieve the phenomenon of a successful collaboration. I do this partially with help from studies published in previ
This article deploys narrative method to explore how young adults in China enrolled in higher education negotiate future intergenerational obligations. The study finds that the process through which filial piety is being renegotiated is complex and sometimes contradictory, and norms and values do not always align with practices, as intergenerational obligations need to be managed in tandem with ob
The prevalence of obesity, type 2 diabetes (T2D) and cardiovascular disease (CVD) is increasing continuously worldwide. These metabolic diseases are associated with many health issues, including increased risk of depression and cognitive impairment. Whole grain (WG) has shown potential to prevent obesity, T2D and CVD. One mechanism can be related to gut fermentation of specific indigestible carboh
The rapid expansion of the university sector has channelled many students into study programs that lead to employment in new kinds of jobs, occupations and professional groups. There are three main reasons why more and more occupations get their training within the university system (a) The qualification and competence level of the labour force has been raised, due to changes in the economy an

Introduction: Widening participation in education by including students from underrepresented groups has been recognized as important for the last decade. During the recent pandemic, the interest in how to make students from different backgrounds feel part of the university, and connected to their studies and peers, has become an even more widespread concern and therefore important to explore furt
