Some numerical methods approximate the Jacobian using finite differences as part of their process. The finite difference method of approximation resembles the limit definition of the derivative. Since a computer cannot handle the mathematical concept of limits, a sufficiently small number has to be chosen as an increment. However, when the increments are chosen outside of certain acceptable ranges
This thesis analyses the media narratives of the COVID-19 pandemic and non-Western ethnic minorities in Denmark. Few months after the outbreak of the pandemic in Denmark, Statens Serum Institut (SSI), the national Danish agency for disease control and research, reported that persons with non-Western background were unproportionally affected by the disease. In the following media debate, there are
PFAS (per- and polyfluoroalkyl substances) are a group of synthetically manufactured chemicals contributing to environmental pollution. The largest point source of PFAS in Sweden is the usage of firefighting foam, and at MSB (Swedish Civil Contingencies Agency) Revinge, firefighting foam has frequently been used. Moreover, PFAS is known to accumulate in plants, and a Salix plant cultivation has be
The expanding market for psychometric tests faces challenges due to the spread of unvalidated tools. The adoption of popular but scientifically unsupported assessment tools can lead to ineffective hiring and misinformed decisions. This thesis aimed to evaluate and conduct a psychometric analysis of a commercially accessible forced-choice personality test - HumanGuide. Archival data (supplied by Hu
Background: Historically, the use of packaging has often been regarded as a necessary evil, associated with unnecessary costs, but needed to enable distribution of goods. Today many companies have begun to realise that the packaging can have a major impact on the supply chain. For Tetra Pak, it is of great importance to be able to offer deeper insights to the costs incurred by their packages, thus
Odling av genetiskt modifierade organismer (GMO) har länge varit ett omdebatterat och politiskt känsligt ämne i EU. Sådan odling väcker en mängd olika betänksamheter och frågor hos europeiska medborgare. I spektrumet återfinns bland annat frågor om risker för miljön och hälsa till socioekonomiska och etiska betänkligheter. Den här uppsatsen undersöker medlemstaters möjligheter att svara upp mot så
There are a lot of debates surrounding the sustainability of liquid biofuel as a means of mitigating some global challenges like climate change and energy insecurity. The European Union (EU) for example has set up renewable energy targets and sustainability criteria. Biofuel is expected to contribute significantly to meet up with these targets. Much of these targets will be met by importing liquid
BAKGRUND På grund av att företag idag har möjlighet att konkurrera globalt genom att flytta produktionen utomlands och att säkra leveranser ifrån alla världens hörn har också inköpsfunktionens roll förändrats. För att nå företagets uppsatta mål är det viktigt att ha en välfungerande inköpsfunktion som jobbar effektivt. Inköpsfunktionen bör inte enbart fokusera på att uppnå det billigaste möjliga iBACKGROUND Through global competition with possibilities for companies to set up production and to secure supply from all over the world the role of purchasing has increased within businesses. In order to achieve business results, a well-working purchasing department plays an important part. To contribute, the purchasing function should not only focus on getting the cheapest price possible, but to
This paper has the purpose to determine whether the attractive rates offered by a local Investment Bank in Mexico under structured products, more specifically under structured notes without principal protection denominated “Dual Structured Notes”, are plausible to get, showing whether the strikes of the implicit options were chosen within critical price values for the foreign exchange rate MXN/USD
Early growth and differentiation of the pancreatic endoderm is regulated by soluble factors from the pancreatic mesenchyme. Previously, we demonstrated that N-cadherin-deficient mice lack a dorsal pancreas, due to a critical role of N-cadherin in dorsal pancreatic mesenchymal cell survival. Here, we show that restoring cardiac and circulatory function in N-cadherin null mice by cardiac-specific ex
A search for doubly charged Higgs bosons decaying to pairs of electrons and/or muons is presented. The search is performed using a data sample corresponding to an integrated luminosity of 4.7 fb(-1) of pp collisions at root s = 7 TeV collected by the ATLAS detector at the LHC. Pairs of prompt, isolated, high-p(T) leptons with the same electric charge (e(+/-)e(+/-), e(+/-)mu, mu(+/-)mu(+/-)) are se
A search for diphoton events with large missing transverse momentum has been performed using proton-proton collision data at is root s = 7 TeV recorded with the ATLAS detector, corresponding to an integrated luminosity of 4.8 fb(-1). No excess of events was observed above the Standard Model prediction and model-dependent 95% confidence level exclusion limits are set. In the context of a generalise
A search for pair-produced scalar particles decaying to a four-jet final state is presented. The analysis is performed using an integrated luminosity of 34 pb(-1) recorded by the ATLAS detector in 2010. No deviation from the Standard Model is observed. For a scalar mass of 100 GeV (190 GeV) the limit on the scalar gluon pair production cross section at 95% confidence level is 1 nb (0.28 nb). When
The integrated elliptic flow of charged particles produced in Pb+Pb collisions at root S-NN = 2.76 TeV has been measured with the ATLAS detector using data collected at the Large Hadron Collider. The anisotropy parameter, upsilon(2), was measured in the pseudorapidity range |eta| <= 2.5 with the event-plane method. In order to include tracks with very low transverse momentum p(T), thus reducing th
Monitoring of permafrost has been ongoing since 1978 in the Abisko area, northernmost Sweden, when measurements of active layer thickness started. In 1980, boreholes were drilled in three mires in the area to record permafrost temperatures. Recordings were made twice per year, and the last data were obtained in 2002. During the International Polar Year (2007-2008), new boreholes were drilled withi
This study sheds light on the connection between collaborative design and the qualitative aspect of ideas in the front end of innovation. The purpose is to showcase how subjective factors within collaborative design have an influence on the quality of radical selected ideas. This research prevailed that mutual understanding of initial set requirements among actors positively impacted the specifici
Objectives: Multi-stakeholder partnership is garnering greater attention worldwide as a means of tackling global wicked problems, implementing sustainable development and leveraging development cooperation. By adopting meta-governance approach, this study investigates the case study of Hoi An - A Green Destination partnership in the waste management context of Hoi An city, Vietnam to understand ho
Academic literatures state that the inadequacy of political will, lack of financial incentives, high costs of renewables, low awareness, and prominence of thermal sources is creating barriers to the adoption of renewable energy, despite the favorable environmental conditions for them in Ghana, especially solar. Within the context of sustainability, understanding the mechanisms that have produced t
