Being, when built, the most powerful neutron accelerator in the world, there will be a large number of potential discoveries at the European Spallation Source (ESS) in Lund. One of the most exciting of these, from a particle physics point of view, is the Coherent Elastic Neutrino-Nucleus Scattering (CEνNS). The goal of the thesis project is to calculate the neutron background in a room that could
Ready-to-eat (RTE) leafy greens offer an appealing way to integrate leafy greens into meals. Unfortunately, these leafy greens can get contaminated with human pathogens such as Salmonella, and Shiga toxin producing Escherichia coli (STEC) at any stage along the manufacturing chain, potentially leading to serious foodborne diseases. Currently, there is no single step in the production and processin
Klimatförändringar är ett av vår tids största miljöhot. Medan länderna i Nord står för de högsta utsläppen är det människorna i Syd som får bära den största bördan. Massajer med sin nomadiska historia konfronteras med svårigheter, då de utöver ett föränderligt klimat måste anpassa sig till ett bofast liv med mindre mark. I massajernas genussystem är mäns och kvinnors roller tydligt uppdelade där m
Binding of immobilized collagen-I (Cn-I) and fibronectin (Fn) by Lactobacillus acidophilus CRL 639 depends on cell-surface proteins. Capsule formation during the stationary growth phase has a negative effect on adherence of Cn-I and Fn. However, cells from the exponential growth phase. which produce no capsule, exhibit maximal binding. Binding is sensitive to trypsin, proteinase K, pronase E, and
We describe a novel method for determining weak association constants of oligomeric protein complexes formed transiently under equilibrium conditions. This type of equilibrium process is recognized as being biologically important, but generally hard to study. Heteronuclear spin relaxation rates measured at multiple protein concentrations are analyzed using relaxation rates predicted from hydrodyna
Immune responses constitute a major way for hosts to defend themselves against parasites. Because hosts do not habitually produce strong responses all the time, immune responses might be costly to produce or maintain. We tested experimentally if the production of a response to a challenge with a novel antigen resulted in a cost in terms of fitness using the highly colonial house martin Delichon ur
Unlimited vacation policies are a rising trend, particularly among startup and tech companies. Giving employees total freedom to choose their vacation days may prove to be beneficial for both company and employees. Within this paper, a qualitative research is presented, with the objective of finding out how unlimited vacation policies (UVPs) influence job satisfaction among employees, and what imp
Over the last decades, dramatic improvements in combinatorialoptimisation algorithms have significantly impacted artificialintelligence, operations research, and other areas. These advances,however, are achieved through highly sophisticated algorithms that aredifficult to verify and prone to implementation errors that can causeincorrect results. A promising approach to detect wrong results is tous
Deep eutectic solvents (DES) and their hydrated mixtures are used for solvothermal routes towards greener functional nanomaterials. Here we present the first static structural and in situ studies of the formation of iron oxide (hematite) nanoparticles in a DES of choline chloride : urea where xurea = 0.67 (aka. reline) as an exemplar solvothermal reaction, and observe the effects of water on the r
Fe-N-heterocyclic carbene (NHC) complexes attract increasing attention as photosensitisers and photoredox catalysts. Such applications generally rely on sufficiently long excited state lifetimes and efficient bimolecular quenching, which leads to there being few examples of successful usage of Fe-NHC complexes to date. Here, we have employed [Fe(iii)(btz)3]3+ (btz = (3,3′-dimethyl-1,1′-bis(p-tolyl
RationaleThere is no effective disease modifying treatment for peanut allergy available. A Phase I safety and tolerability study was performed with a chemically modified, Al(OH)3 adsorbed peanut extract (HAL-MPE1) for subcutaneous immunotherapy (SCIT).MethodsIn a randomized, double-blind, placebo controlled, single-centre, Phase I study, 17 Caucasian subjects with peanut allergy were randomized to
The Usushwana Complex of the south-eastern Kaapvaal Craton (South Africa and Swaziland), intrudes the ca. 3.6-3.1 Ga basement of the craton, as well as the Mesoarchaean volcanic and sedimentary cover succession of the Pongola Supergroup. New high-precision U-Pb dating of gabbros belonging to the Piet Retief Suite of the Usushwana Complex yield ages of 2989 +/- 1 Ma, 2990 +/- 2 Ma and 2978 +/- 2 Ma
The Heat Flux method was extended for the first time towards liquid fuels and used to determine burning velocities under conditions when the net heat loss from the flame to the burner is zero. Non-stretched flames were stabilized on a perforated plate burner at 1 atm. Uncertainties of the measurements were analyzed and assessed experimentally. The overall accuracy of the burning velocities was est
Reduced heart rate variability (HRV) is associated with poor outcome in patients with heart failure (HF). However, the data on predictive value of RR variability during atrial fibrillation (AF) are limited. Therefore, the aim of this study was to evaluate the association between ventricular response characteristics and long-term clinical outcome in the population of ambulatory patients with mild-t
Recycling polymers by site-specific scission into short-chain oligomers/polymers, followed by recoupling these to form the original polymer presents an energetically more favorable shorter-loop chemical recycling in comparison to recycling into monomers. Here, we present the synthesis and polymerization of triaromatic diesters to prepare polyesters with acylhydrazone units as weak structural links
Swedish mining is often envisioned as virtuous, as coinciding harmoniously with quests for sustainability and the cultural survival of indigenous Sami peoples. This chapter posits that Sweden’s sense of exceptionalism in mining is embedded in a colonial/extractive system of knowledge that fails to mention non-capitalist, anticolonial relationalities to nature and ways of life. The normalised statu
