The symbolic elite discourse on the safety and viability of using the insecticide DDT for combating malaria in Africa is marked by extreme dissonance. While some positions within the debate on using DDT for malaria prevention are quite nuanced, others are more extreme if not one-dimensional. The ones who tend to hold more nuanced or centrist positions on using DDT for controlling malaria are often
Climate change is a global threat to human and animals’ well-being on Earth. The threat of climate change has been known for over 30 years and it is now a fact that humans are the main contributing factor to it. Despite this, in 2022 it is no longer an abstract phenomenon, but our reality. One of the reasons why so little has been done to save the environment is people’s lack of or insufficient kn
Border carbon adjustment is an economic instrument being discussed more frequently as a possible solution to address carbon leakage, which is an issue for many developed countries. Developed countries are showing interest in this instrument to protect domestic industries from carbon leakage to countries that do not tax carbon. There is however concerns from developing countries that border carbon
To stay within our planet’s limits and reach the United Nation’s Sustainable Development Goals, there is an urgent need to rethink our current and dominant systems. This thesis focuses on the food system, in particular, and explores how an overarching turnaround in the way we produce and consume food has the potential to trigger and steer a greater transition towards sustainability. However, this
A search is presented for direct top squark pair production using events with at least two leptons including a same-flavour opposite-sign pair with invariant mass consistent with the boson mass, jets tagged as originating from -quarks and missing transverse momentum. The analysis is performed with proton-proton collision data at collected with the ATLAS detector at the LHC in 2012 corresponding to
Objective. New proposed definitions of chronic kidney disease necessitate the development and use of simple and accurate methods for estimating glomerular filtration rate (GFR). Plasma cystatin C has been shown to be a more reliable GFR marker than creatinine and formulae for estimating GFR have been reported. The purpose of this study was to validate a cystatin C-based GFR prediction equation in
Background. Randomized trials have shown that icodextrin reduces the volume of extra-cellular fluid (ECFv) with variable effects on residual renal function. To explore this fluid shift and its possible mechanisms in more detail, prospectively collected data from one such trial, including measures of inflammation (C-reactive protein, tumor necrosis factor-a, albumin and low and high molecular weigh
The results of a search for pair production of light top squarks are presented, using 4.7 fb(-1) of root s = 7 TeV proton-proton collisions collected with the ATLAS detector at the Large Hadron Collider. This search targets top squarks with masses similar to, or lighter than, the top quark mass. Final states containing exclusively one or two leptons (e, mu), large missing transverse momentum, ligh
Shredder residues of end-of-life vehicles and white goods are a complex waste stream, which nowadays most often is disposed of at industrial landfills. This paper describes the most important findings concerning the complex composition of the landfill leachate and its on-site, year-round treatment under cold-climate conditions. A 3-year investigation has confirmed that concentrations of different
This Letter presents the results of a direct search with the ATLAS detector at the LHC for a Standard Model Higgs boson of mass 110 <= m(H) <= 130 GeV produced in association with a W or Z boson and decaying to b (b) over bar. Three decay channels are considered: ZH -> l(+)l(-)b (b) over bar, WH -> lvbb (b) over bar and ZH -> v (v) over bar(b) over bar where l corresponds to an electron or a muon.
Mesenchymal stroma cells (MSCs) have a high potential for novel cell therapy approaches in clinical transplantation. Commonly used bone marrow-derived MSCs (BM-MSCs), however, have a restricted proliferative capacity and cultures are difficult to standardize. Recently developed human embryonic stem cell-derived mesenchymal stroma cells (hES-MSCs) might represent an alternative and unlimited source
Background: ABO genotyping is complicated by the remarkable diversity at the ABO locus. Recombination or gene conversion between common alleles may lead to hybrids resulting in unexpected ABO phenotypes. Furthermore, numerous mutations associated with weak subgroups and nondeletional null alleles should be considered. All known ABO genotyping methods, however, risk incorrect phenotype predictions
The determination of elemental abundances plays an important role inunderstanding the atmospheric processes that lead to anomalies inspectra of chemically peculiar stars. Ongoing study of the HgMn star χ Lupi has defined much of the elemental abundance distribution but progress is dependent upon the availability and accuracy of the atomic data. Here we present experimentally determined wavelengths
The first ESR spectroscopic evidence of a bimolecular homolytic substitution (SH2) reaction in a 77 K solid phase was presented, where radicals were substituted for the CH3 group of methylsilane and methylgermane (CH3XD3, X = Si, Ge). The radicals were generated by in situ UV-photolysis of CD3I in the solid CH3XD3 in an ESR cavity at 77 K. Using the selectively deuterium labeled compounds, it was
Populations of European starlings have declined over large parts of northern and western Europe during the last 20 years. It has been suggested that reduced availability of pasture in the agricultural landscape was one reason for this decline. To investigate this, breeding colonies for starlings were established in southern Sweden, in agricultural landscapes with different availabilities of pastur
The environmental impact of poultry mainly arises from their feed. Therefore, this study aimed to investigate the environmental impact of three Swedish poultry feeds and identify how their environmental performance could be improved. This was done with the method of life cycle assessment where the environmental impact categories of, climate change, acidification potential, eutrophication potential
Each year children and adults are injured in accidents caused by chemicals, usually due to incorrect use of the products. Studies have shown that children are more sensitive to chemical products and injuries that occur during childhood could cause lifelong consequences. In order to prevent accidents caused by chemicals it is important to label and package these products appropriately in accordance
