The Gaia spacecraft presents an unprecedented opportunity to reveal the population of long period (a > 1 au) exoplanets orbiting stars across the H-R diagram, including white dwarfs. White dwarf planetary systems have played an important role in the study of planetary compositions, from their unique ability to provide bulk elemental abundances of planetary material in their atmospheres. Yet, very
Coagulation, complement, and innate immunity are tightly interwoven and form an alliance that can be traced back to early eukaryotic evolution. Here we employed an ecoimmunological approach using Tissue Factor Pathway Inhibitor (TFPI)-1-derived peptides from the different classes of vertebrates (i.e. fish, reptile, bird, and mammals) and tested whether they can boost killing of various human bacte
Streptococcus pyogenes is known to cause both mucosal and systemic infections in humans. In this study, we used a combination of quantitative and structural mass spectrometry techniques to determine the composition and structure of the interaction network formed between human plasma proteins and the surfaces of different S. pyogenes serotypes. Quantitative network analysis revealed that S. pyogene
Parental care can be partitioned into traits that involve direct engagement with offspring and traits that are expressed as an extended phenotype and influence the developmental environment, such as constructing a nursery. Here, we use experimental evolution to test whether parents can evolve modifications in nursery construction when they are experimentally prevented from supplying care directly
Injuries to the spinal column and spinal cord are a major cause of disability, affecting predominately young, healthy individuals. The majority of the spinal injuries (60%) affect young healthy males between 15 and 35 years of age, with important socioeconomic consequences, and the costs of lifetime care and rehabilitation are extremely high. As the longevity of the general population increases, t
Viral infections predispose to the development of childhood asthma, a disease associated with increased lung mast cells (MCs). This study investigated whether viral lower respiratory tract infections (LRTIs) can already evoke a MC response during childhood. Lung tissue from young children who died following LRTIs were processed for immunohistochemical identification of MCs. Children who died from
This chapter outlines some of the key concerns with criminalising sex-selective abortion (SSA) in China and India, highlighting that it offers no identifiable options for sustainable, women-centred, progressive change. Instead, the criminalisation of SSA sits firmly within other forms of carceral feminism. Framing SSA as “female foeticide,” “femicide,” or “gendercide” is problematic, as such terms
The intestinal lumen contains an abundance of bacteria, viruses and fungi alongside ingested material that shape the chronically active intestinal immune system from early life to maintain the integrity of the gut epithelial barrier. In health, the response is intricately balanced to provide active protection against pathogen invasion whilst tolerating food and avoiding inflammation. B cells are c
This chapter critically engages with a central policy norm developed by key international actors working on statelessness and refugeeness over the last three decades. This is the norm that for stateless refugees their refugeeness effectively trumps their statelessness. I term this norm, which arbitrarily separates and ranks statelessness and refugeeness, the “protection hierarchy”. This norm is in
Urban greening is often thought of as a tool for aligning developmental and environmental goals, but it is also a tool for magnifying the city. It exposes and expands almost invisible dimensions of our hyperlocal environment. Greening has become one of the strongest mechanisms for transforming these preferences from a figurative guide for action into the literal cities the authors inhabit. In the
Inteins are self-splicing protein elements found in viruses and all three domains of life. How the DNA encoding these selfish elements spreads within and between genomes is poorly understood, particularly in eukaryotes where inteins are scarce. Here, we show that the nuclear genomes of three strains of Anaeramoeba encode between 45 and 103 inteins, in stark contrast to four found in the most inte
The nasal mucosa is the first immunologically active site that respiratory viruses encounter and establishing immunity at the initial point of pathogen contact is essential for preventing viral spread. Influenza A virus (IAV) in humans preferentially replicates in the upper respiratory tract (URT) but mouse models of infection result in lower respiratory tract infection. Here, we optimize IAV inoc
Svinn som uppstår vid produktion av skinka och åtgärder för en hållbar produktion Produktion av skinka är en komplex process med många steg och inverkande parametrar. Svinn uppstår mer eller mindre i samtliga processteg i olika former: blodliknande vätska, bortsorterade skivor på grund av torrt eller håligt kött, förångad vätska med mera. Det finns en stor potential för minskat svinn men det krävWaste is an issue in the food industry which impacts both the economy and the environment negatively. Atria is a food company aiming to reduce the waste. This report investigates the waste, its origin, and causes in the ham production process. The aim of this report is to identify waste and possible solutions. In this report both qualitative data and quantitative data were collected and analysed.
This thesis deals with an approach in how to structure global governance, proposed by an Australian political scientist John S. Dryzek, called ‘Discursive democracy’. This thesis presents the approach, goes through the different aspects of it and tries to give the reader a sufficient understanding of the approach. The thesis offer an evaluation of the approach through a process where the approach
The European Commission has acknowledged the lack of cross-border utilization of losses. Companies operating internationally want to have a possibility to offset losses against taxable profits at the same time or as soon as possible after the losses incurred. If no such possibility is at hand, a cash-flow disadvantage arises and also, it leads to segmentation of the internal market. The asymmetrie
Video on Demand (VoD) is a service that delivers video seamlessly to the consumer on demand. This thesis examines the consumers’ opinion on the different VoD services that exists on the Swedish market. To conduct our research we collected quantitative data by using a survey and then conducted a qualitative analysis. As a theoretical framework we used our own modified version of The DeLone and
The aim of this study is to contribute to the existing literature on co-creation in investigating consumers’ motives for participation on the one hand and possible effects of this participation on brand knowledge on the other. It thus provides a link between co-creation, motivation, and branding literature. A constructionist ontological stance and interpretive epistemology led us to the research p
As part of a program designed to elucidate the excited state properties of key eumelanin building blocks, we report herein a study of 5,6-dihydroxyindole (DHI) in phosphate buffer at pH 3 and pH 7 using femtosecond transient absorption spectroscopy. The transient absorption changes following excitation at 266 nm were used to directly monitor relaxation of the excited states. It was found that the
