The invention of computers revolutionized the way of doing science and in particular the field of mathematics. Computers were faster than any human mind in doing calculations and they did not make mistakes opening a wide range of possibilities that earlier where in practice uncomputable. Scientists observe the behavior of nature and find mathematical equations that model the different phenomena. IThe efficient simulation of thermal interaction between fluids and structures is crucial in the design of many industrial products, e.g. turbine blades or rocket nozzles. The main goal of this work is to present a high order time adaptive multirate parallel partitioned coupled method for the efficient numerical solution of two parabolic problems with strong jumps in the material coefficients that

Recent technological advancements have revolutionized tree inventory methods for the forest industry. The development of terrestrial laser scanning (TSL) and automatized tree recognition software to estimate crucial tree parameters such as diameter at breast height (DBH) has made the inventory work faster and more reliable. Forest managers can quickly acquire large amounts of data to safely estima

Popular Abstract in English Nowadays, the majority of energy production comes from combustion which is universally linked to daily human activities. Public awakening of the environmental effects of combustion pollution evokes extensive research activities in improving combustion efficiency and reducing pollutant production. Development of combustion processes also includes the use of renewable bioThe work presented in the thesis concerns the developments of laser-based diagnostics and its application to the study of turbulent premixed combustion. The diagnostic developments, mainly concerned with planar laser-induced fluorescence (PLIF), are intended to provide instantaneous visualization of the key species originating from the combustion processes involved in the burning of hydrocarbons

Car prevalence in society has a negative effect on both local and global environments. One way to tackle these problems is to restrict car traffic in city centres, this comes not only with effects on the environment. How car free zones can affect retail in cities is examined in this study. The study takes place in ten retail shops in the city centre of Lund along three streets. Customers are aske

The increasingly frequent use of forensic evidence in the prosecution of criminal cases should in the long run result in increased analysis of its effectiveness. To date, such analysis has been limited, most probably due to rights of parties to use forensic evidence to support their respective arguments in cases and the rights of the courts to assess and rely on such evidence in criminal cases. Pr

Soils play a critical role in the carbon (C) cycle by regulating the atmospheric carbon dioxide (CO2) levels, and correspondingly the Earth’s climate. However, there are still countless questions of how biological and geochemical soil processes affect the C cycle. To be able to predict future implications on the Earth’s climate, we need to understand these processes. Globally, soils store more C tIron oxide nanoparticles are involved in several important biogeochemical processes. The interfaces between aqueous solutions and iron oxide nanoparticle surfaces are found everywhere in nature, and the chemical and microbial processes occurring at these complex interfaces control e.g. nutrient and contaminant availability and transport. Recently, it has been shown that certain ectomycorrhizal (EC

While foreign direct investments (FDI) are promoted as a vehicle for economic development their environmental consequences are less established. This study tests the hypotheses that 1) FDI led to environmental degradation in form of increased greenhouse gas emissions during Sub-Saharan Africa´s recent growth spurt but that 2) this impact was felt to a lesser extent in countries with a higher quali

Through an autoethnographical reflection the aim of this paper is to explore the clash between high ethical ambitions in educative relationships and demandingbehaviours. What happens when the map does not resemble reality, when, forexample, someone in the educative relation does not behave as expected and themethods are challenged? What increases or decreases the risk that the teacher (orsimilar)

The global food industry is the second main contributor to climate change whilst climate change also poses threats to future food security (Ritchie & Roser, 2020). One of the suggestions to decrease the environmental footprint of consumption and increase the resilience of food systems, is the shift to local production and consumption (Stein & Santini, 2021; Van Gameren et al., 2015). Howev

The purpose of this paper is to study the impact the coal industry in el Cerrejón has had on the indigenous Wayúu population at the north of Colombia. The issue is addressed in through a human right lens discussing the importance of environmental and indigenous rights, which are not yet included in any legal document of the United Nations. The topic of environmental and indigenous rights is furthe

To become a member of the European Union, the applicant country must meet the accession criteria established in the Copenhagen Declaration, commonly referred to as the Copenhagen criteria. While these criteria serve as formal guidelines, previous research has shown that they alone cannot explain when and how a country will join the union. Instead, it is argued that the justification and discursive

The tear opening study is conducted with an example from the Tetra Pak package industry, the Tetra Top package. The top of the package is constructed by a injection molded low density thermoplastic. The package is opened with a tear opening located on the top part. In order to make tear opening more versatile, studies how opening forces reacts upon material modifications and alternative geometry h

A recently developed, simple immunological method, diffusion-in-gel ELISA, has been adapted for class-specific determination of rheumatoid factor (RF). Evidence was obtained of an analytical error due to interaction between RF and antigenic determinants on the Fc part of the indicator immunoglobulin (Ig) molecules used. This was eliminated by replacing the usual indicator reagent, complete Ig mole
