Fallstudie av en skogsplantskola – rester av DDT i jorden utgör än idag en hög risk för rovfåglar och rovdjur. Trots att användningen av insektsgiftet diklordifenyltrikloretan (DDT) sedan länge varit förbjuden i Sverige finns rester kvar i jorden på platser där det använts. Anledningen till att det finns kvar är att DDT är mycket svårnedbrytbart. Eftersom detta ämne även har förmåga att bioackumuAlthough prohibited since decades, dichlorodiphenyltrichloroethane (DDT) and its metabolites still remain in the soil and pose a threat to ecosystems, where especially birds are susceptible to toxic effects. In this thesis, a model developed in the 1990s was used and updated in order to estimate the risks of DDT to top predators at a forest-plant nursery site. Unusually high concentrations of DDT

Av miljö- och hållbarhetsmässiga skäl finns idag ett ökat intresse att använda trä som byggnadsmaterial. Björk har historiskt sett inte används i lastbärande strukturer på grund av dålig beständighet och låg formstabilitet. Genom den kemiska modifieringsprocessen acetylering, kan båda dessa egenskaperna förbättras. För att kunna använda det modifierade träet i lastbärande strukturer måste man dockModication of wood is carried out to increase the durability and dimensional stability of wood, and one of the modication methods is acetylation. Acetylation of wood means that polymers in the cell wall react with acetic anhydride. Today, acetylated wood is rarely used in load-bearing structures and there are only a few studies on how the fracture characteristics are affected by acetylation. A stu

Problem – Although core values and conflicts have been thoroughly explored in organizational theory, few attempts have been made to explain their combined impact on the entrepreneurial environment. Since investors and entrepreneurs act as the core decision makers within a venture, understanding the impact of their underlying motivations in relation to conflicts can provide valuable insights. Aim –

The Museum in Helsinki explores the architectural challenges in adding properties to a culturally significant site without disturbing it. The framework for this thesis is given by an open architectural competition with the objective to find a suitable extension to the National Museum in Helsinki. How does one design a suitable extension to a culturally significant and fragile site?

After recieving the diplomas from the idea competition win together with two colleagues nothing really happened in the Granite Castle in Itäsatama, Hanko. Some makeshift flea markets and coffee booths were put in the empty shell of the previous granite quarry but in the greater scale it remained a shadow from its former past. Hanko’s unequable tourist season concentrates during peak summer leaving

Building permit automation has become a rising international topic in the past decade due to its convenience and efficiency. Automated compliance checking saves time and resources, which is beneficial for the construction industry. Researchers have already automated parts of the building permit process and the results proved that automated building requirement compliance checking is efficient. Thi

Under de senare åren har debatten om polisens omorganisation väckt många heta diskussioner. Omorganisationens syfte var att skapa tydligare styrning och bättre förutsättningar för högre kvalitet, ökad kostnadseffektivitet, större flexibilitet och förbättrade resultat inom den polisiära verksamheten genom att göra en enhetlig polisorganisation istället för 21 mindre polismyndigheter. Uppsatsens sy

Linking conflict events and cropland development in Afghanistan, 2001 to 2011, using MODIS land cover data and Uppsala Conflict Data Programme This thesis describes changes in land cover between 2001 and 2011 in Afghanistan, and analyzes the influence of conflict events on cropland development. How did fighting intensity affect cropland areas in Afghanistan, did cropland areas decrease or incre

2018 utlystes en arkitekttävling om ett nytt gestaltningskoncept för Lunds stadshall, en byggnad av Klas Anshelm från 1960-talet. I detta examensarbete undersöker jag vilka metoder man kan arbeta med och hur en byggnad som stadshallen kan transformeras till något nytt. Genom platsstudier, analyser av Anshelms byggnader och utredningar om begreppen finrum och vardagsrum kunde jag komma fram till va

Klimatförändringar och behovet av en mer hållbar samhällsutveckling är något som de flesta är medvetna om i dagens samhälle, inte minst i Sverige. Det kommer bland annat att påverka klimatet i svenska fjällen och de orter som är beroende av fjällturismen. Åre är en av dessa svenska turistorter och även den största, med ett högt exploateringstryck, vilket ställer krav på hållbar bebyggelse. ProblemThe subject regarding climate change and the need for a more sustainable development is well-known in today's society, especially in Sweden. It will for one affect the environment in the Swedish mountain areas and the resorts dependent on the tourism that these areas attract. Åre is one of these Swedish resorts and is also the biggest one with high exploitation pressure, which places demands o

This thesis examines the relationship between gender equality, demographic change, and economic growth for the context of Sweden, 1870-1990. Large-scale developments changed a society with relatively little gender equality in the late nineteenth century to the egalitarian welfare state that we know today. Using personally-collected data at the Swedish county-level, a measure of gender equality - t

This thesis explores the discourse of Executive Order 13767 by applying Carol Bacchi’s discourse analytical method What’s the problem represented to be on the document, surrounding debates and speeches. Signed by President Donald Trump, it states that a wall should be built on the border between the US and Mexico. The thesis presents the problem representations in the policy and examine how they c

Historically, the field of glacial geology has put much focus on the processes within the subglacial environment, their effects on unconsolidated sediments and the landforms they produce. Subsequently, the impact of subglacial processes is fairly well documented and understood regarding unconsolidated sediments. However, except for processes of abrasion and quarrying, not much focus has been dedic

Modern technology plays a significant role in transforming workplaces and creating an improved business performance. The technological advancements have enabled organizations to utilize technology platforms for increased brand performance since brand and branding have become highly important in today’s organizations. Our interest in the topic of technology in the background of brand-centred contro

This thesis identifies the increasingly hegemonic narrative surrounding green capitalism, what the narrative entails and how the discourse may manifest materially in policies and development programs. Specifically, the thesis explores how the narrative of green capitalism and green growth is expressed in the discourse in communication in the case of P4G – Partnering for Green Growth and Global Goa

Mörk materia upptäcktes redan på 1930-talet av astronomer via sin enorma gravitationella påverkan på galaxer. Trots detta, har alla försök att hitta dess beståndsdelar via experiment misslyckats. Ledande modeller för den mörka materians natur brukar beskriva den som uppbyggd av så kallade ”WIMP:s” (weakly interacting massive particles) som översätts till ungefär: ”svagt interagerande massiva partiRecently, a number of experiments have been proposed with the aim of finding light dark matter. In particular, the proposed LDMX experiment is meant to utilize electron scattering off metal nuclei to excite dark matter emissions. Motivated by this, we construct an event generator for electrons scattering off metal nuclei. The relevant kinematics are presented in detail. The matrix element for the

The rate of global urbanization in the 21st century has been unprecedented especially in the African and the Asian continents. Urbanization typically causes a removal of natural vegetation and replacement of same with impervious and non-evaporative urban materials with high heat capacity and low solar reflectivity. The alteration of the natural land cover due to urbanization causes a change in the
