SLU (Sveriges Lantbruksuniversitet) har ett pågående projekt i ett område i södra Skåne sedan 1989 där de studerar hur bekämpningsmedel i åar korrelerar med vad som används på åkrarna. Ett nytt projekt, initierat av SGI (Statens Geotekniska Institut), kallat PEGASUS (PEsticide occurrence in Groundwater, A Study for sustainable Use in Skåne) har påbörjat en undersökning i samma område för att studeSLU (Swedish University of Agricultural Sciences) have had a project ongoing in a catchment area in southern Skåne for 20 years where they study how pesticide occurrence in surface waters correlate to the sort and amount used on the agricultural fields. A new project started by SGI (Swedish Geotechnical Institute) called PEGASUS (PEsticide occurrence in Groundwater, A Study for sustainable Use in

During the past decades there is a growing interest to include a cultural dimension in the debate on sustainable development. In this thesis I explore how culture, and more specifically the Flemish cultural sector, contributes to the transition to a sustainable society. By means of case studies, I examine how cultural organizations perceive their role in the transition process and how they transla

This thesis presents the work I did for the inclusive search for anomalous production of same charge lepton-pairs, originating from the collision point, at sqrt(s) = 8 TeV with the ATLAS detector at the LHC using the 2012 data. I optimized the selection criteria for isolated electrons and muons, calculated the so-called "fake factors" and "fake factor" systematic uncertainties

Datering med accelerator? Måhända låter det otympligt, men när det handlar om att datera med hjälp av sällsynta slag av grundämnen kan varje atom räknas. Då handlar det om att kunna räkna enskilda atomer, vilket är möjligt med acceleratorbaserad masspektrometri, AMS. Lunds Universitet har en accelerator anpassad just för den här sortens mätningar, vilken främst nyttjas av institutionerna för fysiFor decades, accelerator mass spectrometry (AMS) has been used for radiocarbon dating. The background of this technique is outlined along with an in-depth look at the graphitization process used to prepare samples for AMS analysis. The technology necessary to achieve the vacuum quality needed in graphitization and accelerator mass spectrometry is discussed as well. The graphitization system belong

Reklam kan inte ses som en isolerad kommunikation mellan företag och konsumenter, den existerar i samtiden, i en kontext och i ett samhälle som låter sig påverkas av den. Vad som exponeras i det offentliga påverkar de uppfattningar och föreställning människor har om omvärlden i ett långsiktigt perspektiv. Syftet med studien är att undersöka och skapa förståelse för hur reklambyråer hanterar balans

The Euler equations consist of conservation laws and describe a fluid in motion without viscous forces and heat conduction. They are non-linear and the solutions are often discontinuous. Therefore proofs of convergence are hard to give and the existing results are lacking. A new concept are weakly imposed characteristic boundary conditions, where a priori given boundary data only enter the scheme

Problems: A driving force for change in business is the availability of enterprise resource planning systems (ERP-systems). They have a great impact on companies, not only because they constitute exceptionally large investments, but also because they hold the promise of integrating companies more closely, hence, they should be important in the pursuit of synergy. In SCA Packaging, the landscape of

Open data is broadly expected to generate innovation and economic value for both the public and private sector. Though the diffusion of open data has kept a fast pace, knowledge of visualisation and points of access of open data remains low. Moreover, literature of the private-sector application of open data is still scarce. The first objective of this thesis is to increase the knowledge about the

LDMX is a fixed target experiment designed to search for light dark matter. The experiment will search for dark matter signatures using missing momentum and energy in events with electrons scattering in the target. Part of the experimental setup in this search is a high granularity electromagnetic calorimeter to accurately measure the energies of recoil electrons. In this thesis artificial neura

Det finns ett växande behov av miljövänliga sätt att transportera sig och därför har elcykeln slagit stort i Sverige. Elcykeln används ofta som transportmedel till och från jobbet men har potential att användas i andra sammanhang också. Miljöpåverkan orsakad av transport under semesterresor har uppmärksammats på senare tid. Samtidigt ökar efterfrågan på soft adventures, bekväma och tillrättalagda There is a growing demand for environmentally friendly ways of transportation, and therefore the electric bicycle has been booming in Sweden. The electric bicycle is often used as means of transportation to and from work, but has potential to be used in other situations as well. The environmental impact caused by transportation during holidays has recently gained attention. At the same time the de

Due to its high vulnerability, permafrost is one of the key features studied in the field of climate change impacts. Permafrost is widespread in the Arctic region. The majority of the area underlain by permafrost is however difficult to access for in-situ monitoring and it is difficult to get an overview of the current state of permafrost in many areas. Permafrost modeling provides a solution whi

Tidigare forskning visade på att ledarskapsstilarna i CPE-modellen (Change-, Production- & Employee-centered leadership) är olika effektiva. Annan forskning visade att tidigare prestationer har en positiv korrelation till collective efficacy. Sambandet mellan CPE-modellen och collective efficacy inom idrottslag har däremot inte undersökts. Studiens frågeställning var därför att undersöka hur dPrevious research showed that the three leadership styles in the CPE-model (Change-, Production- & Employee-centered leadership) varies in efficiency. Further research showed that prior performances has a positive correlation with collective efficacy. The relationship between the CPE-model and collective efficacy, however has not been researched. This study, therefore, aimed at answering wheth

This thesis covers established procedures for the successful and attempted immobilization of lipases and phospholipases to various hydrophobic support materials, utilizing a rotating bed reactor, magnetic stirrer and tube-rotator. The design of a robust platform was established with great instrumental knowledge and proper conditioning for the creation of efficient immobilizations and activity assa

Highly glazed spaces are continuously increasing in popularity due to architectural attractiveness. However, increased use of glass often jeopardizes thermal comfort in several ways and problem of overheating is one of them. A way to face this problem is to appropriately use solar control mechanisms. However, a proper selection of solar control mechanisms from an early design stage is a complex ta

The main objective of this thesis is to present the article "An estimate of the condition number of a matrix", written by Cline et.al., which describes an algorithm for obtaining a reliable order of magnitude estimate of the condition number of a matrix in O(n^2) operations. In addition, the thesis introduces an iterative process for estimating the condition number in the 2-norm with arb

In this master thesis we consider some phenomenological aspects of two-Higgs-doublet models, both elementary and composite ones. The emphasis is on calculating and understanding first order phase transitions in such models, constrained to be in agreement with existing collider data on the Higgs sector. We also consider the contribution to the gravitational wave background of the universe that woul

Ultrasound optical tomography is a medical imaging modality that combines ultrasound and light to improve the low resolution of optical imaging caused by scattering in tissue. Photons passing through an ultrasound pulse have a probability of being frequency shifted. By filtering out these photons and analysing them, images with optical contrast and ultrasound resolution can be obtained. In this t
