An efficient immune system is essential to the survival of many animals. Sociality increases risk of pathogen transmission, which should select for enhanced immune function. However, two hypotheses instead predict a weakened immune function: relaxed selection caused by social immunity/protection, and reduced efficacy of selection due to inbreeding, reproductive skew and female bias in social speci
Biological membranes constantly change their shape in response to external stimuli, and understanding the remodeling and stability of vesicles in heterogeneous environments is therefore of fundamental importance for a range of cellular processes. One crucial question is how vesicles respond to external osmotic stresses, imposed by differences in solute concentrations between the vesicle interior a
This thesis focuses on design, processing and electro-optical investigations of two- and three-terminal photodetectors based on large arraysof around three million n+-i-n+ InP nanowires with embedded InAsP quantum heterostructures for broadband detection. The first part of thethesis work dealt with a general investigation of the room-temperature optoelectronic behavior of two-terminal photodetecto
Viruses compete with each other for limited cellular resources, and some deliver defense mechanisms that protect the host from competing genetic parasites 1. PARIS is a defense system, often encoded in viral genomes, that is composed of a 55 kDa ABC ATPase (AriA) and a 35 kDa TOPRIM nuclease (AriB) 2. However, the mechanism by which AriA and AriB function in phage defense is unknown. Here we show
Prostate-specific antigen (PSA) was discovered in the 1970s, with assays to detect PSA in blood approved by the US Food and Drug Administration in 1986. Almost from the very beginning, its role as a prostate cancer marker has been severely misunderstood. One of the most well-known misconceptions is that prostate cancer detectable by elevated PSA in asymptomatic men requires treatment, irrespective
Temperature estimation plays a vital role across natural sciences. A standard approach is provided by probe thermometry, where a probe is brought into contact with the sample and examined after a certain amount of time has passed. In situations where, for example, preparation of the probe is non-trivial or total measurement time of the experiment is the main resource that must be optimized, contin
Leonardo da Vinci Community Vocational Training Action Programme’s pilot project within Geographical Information Science (GIS), should be implemented over a three year period, 2002-2005. The main objectives of the project is to establish co-operation between European Universities and GIS user organisations and to develop modularised courses intended for Internet based learning, establish links of
Recent literature has suggested how late-medieval families may have used financial markets to navigate the life cycle. Precious little is known about the precise connections between the life cycle and family on the one hand and investments in financial instruments on the other, though. We analyse late-medieval investment behaviour using a new dataset of hundreds of life annuities. Our data give ag
Background: Personal history of type 2 diabetes mellitus (T2DM) is associated with a lower incidence of prostate cancer, but the underlying mechanisms are largely unknown. We hypothesized that genetic factors that are involved in the development of T2DM might protect against prostate cancer. Methods: We used a few Swedish registers, including the Swedish Multigeneration Register and the Cancer Reg
How specialization of consumers with respect to resources varies with respect to latitude is poorly understood. Coexistence of many species in the tropics might be possible only if specialization also increases. Alternatively, lower average abundance of more diverse biotic resources in the tropics might force consumers to become more generalized foragers. We examine levels of reciprocal specializa
‘Altare beate Marie presentacionis’– a new reconstruction of the ruined altar belonging to Archbishop BrostrupBefore the extensive interior alterations of Lund Cathedral in 1833, only six stone altars, four relatively complete retables, and one fragmentary Madonna remained from the once vast amount of Catholic altars. At present only the stone altar in the crypt retains its medieval position, and
Bird collisions with overhead power lines can cause power outages and raise ecological concerns. This thesis analyses bird-related power disruptions in E.ON Energidistribution AB’s Swedish power grid during the period 2009–2025. The aims are to analyse the impact of bird-related outages relative to other causes and to evaluate whether bird diverters reduce such disruptions. The study is based on d
Nyhamnen, som en gång definierades av industri, färjor och hamnfunktioner planeras bli Malmös nya stadsdel med tusentals bostäder, arbetsplatser och nya stadsfunktioner. Idag står platsen tom, karaktäriserad av stora asfalterade ytor, åtskilda av staket. Platsen befinner sig i väntan, på tröskeln mellan då och sen. I närheten av Nyhamnen finns två materialbanker. En stor del av det här arbetet hNyhamnen, once defined by industrial activities, ferry terminals and harbour functions, will in the future become Malmö’s new neighborhood with thousands of new housings, workplaces and city functions. Today the area stands empty, defined by large vacant spaces closed of by fences. The area awaits in silence, standing on the threshold between past and future. In close proximity to the site, ther
In Sweden, deacons are at increased risk of experiencing work-related stress and its consequences, including burnout. The research area on stress amongst deacons, or Christian social workers in general, is limited which motivates research on this area. By looking at the two organizational theories of role stress and effort-reward imbalance, this study aims to examine the linkages between stress am
Integrating quantum systems with machine learning models gives rise to quantum machine learning, which introduces new data processing and analysis capabilities. One approach is the use of quantum extreme learning machines, which combine a physical quantum reservoir with a single-layer artificial neural network. The advantage of utilizing a quantum reservoir, instead of a classical system, lies in
Studien undersökte hur auditivt minne påverkas av att höra en röst som talar med dialekt på ens eget modersmål (i detta fall svenska) i jämförelse med att höra en röst som talar med brytning på ett annat språk (i detta fall franska). Auditivt minne är ett relevant område i forensiskt sammanhang då det finns bristfällig forskning gällande öronvittnen och dialekters och brytningars påverkan på öronvThe present study researched how auditory memory is affected by hearing a voice that speaks with a dialect in one’s own mother tongue (in this case Swedish) in comparison to hearing a voice that speaks with an accent in another language (in this case French). Auditory memory is a relevant field in forensic context since the research concerning earwitnesses and the impact of dialects and accents on
The amount of people in Sweden that studies on a higher level has increased a fair amount during the period 1990-2020. With a higher level of education, the graduates expect to be compensated for the time spent, with, for instance, a higher salary. Although during the same time studied, data and statistics show a negative trend regarding the profitability of the education, meaning that graduates r
