A focused MeV proton beam at the Lund Ion Beam Analysis Facility has been used to induce radiation damage in transmission semiconductor detectors. The damage alters the response of detectors and degrades their charge transport properties. In this work, the radiation tolerance of ultra-thin silicon PIN detectors was studied as a function of proton fluences and detector thickness using a scanning pr
The best method to evaluate the seismic site response is by means of borehole vertical arrays that use earthquake records from different depths. In this paper we introduce the implementation of a single borehole sensor system (synchronized to a sensor on the surface) that is fixed at variable depths within a single well. This system is used for recording small amplitude earthquake signals at varia
Aggregation of the amyloid β-protein (Aβ) is believed to be involved in Alzheimer's disease pathogenesis. Here we have investigated the importance of the aromatic rings at positions 19 and 20 for the aggregation rate and mechanism by substituting phenylalanine with leucine. Aggregation kinetics were monitored as a function of time and peptide concentration by thioflavin T (ThT) fluorescence, the a
This paper is the state of the art of charcoal signal studies (macro-, meso- and micro-charcoal) that have been carried out at the Epigravettian settlement of Mezhyrich. This work took part of the French ANR project "Mammouths". Charcoal signals have been found in both natural and archaeological (pits and activity areas) deposits that have been sampled during the 2007-2008 archaeological excavatio
A bioanode with high current density and coulombic efficiency was developed by co-immobilization of pyranose dehydrogenase from Agaricus meleagris (AmPDH) with the dehydrogenase domain of cellobiose dehydrogenase from Corynascus thermophiles (recDHCtCDH) expressed recombinantly in Escherichia coli. The two enzymes were entrapped in Os-complex modified electrodeposition polymers (Os-EDPs) with spec
Popular Abstract in Swedish Mögel i byggnader är ett vanligt problem som kan orsaka en dålig innemiljö och påverka hälsan hos de personer som vistas i byggnaden. Kostnaderna för att åtgärda problemen kan vara omfattande. Att redan vid planeringsstadiet av en byggnad ta hänsyn till risker för mögelväxt kan leda till minskat antal mögelskador i framtiden och ett mer hållbart byggande. Mögelväxt är The susceptibility to mould growth varies between building materials. The factors that most affect mould growth, the relative humidity (RH) and temperature also vary in different parts of buildings. One way of preventing the growth of mould in buildings is therefore to choose building materials that can withstand the expected conditions. It is thus crucial that data are available to allow the corr
The aim of this essay was to illustrate how poor women with children in Nicaragua saw themselves and the role they played. For the realization of this study I used the qualitative method consisted in interviews of six women who live in a poor neighborhood in the city of León. To be able to reach this essay’s purpose, it was of the utmost importance to answer on what was their role, what conception
According to the Convention on the Rights of the Child (CRC) in all actions concerning children, whether undertaken by public or private social welfare institutions, courts of law, administrative authorities or legislative bodies, the best interests of the child should be a primary consideration (CRC article 3 p. 1). However, it is not regulated in the law or in CRC what is considered to be the ch
The purpose of our essay was to examine what treatment women have had, who in their teenage years had eating disorders, how they have experienced this treatment and how they live today. Our central questions were; what was their experience of the treatment, how are their lives today, has the eating disorder and the treatment affected how the women live today and what kind of treatments are there?
Bostads- och servicesektorn utgör 40 procent av Sveriges totala energianvändning. Endast småhus står för drygt 8 procent. Energin som används i småhus går i huvudsak till uppvärmning och varmvatten. 2020 var direktverkande el den vanligaste energikällan för uppvärmning av småhus (Energimyndigheten 2022). Elpriset har stigit kraftigt under det senaste året. Detta kan eventuellt ha påverkan på boendThe building and service sector consume 40 percent of Sweden’s total energy use. Which of only single-family houses are responsible for 8 percent. The energy used in single family houses mainly goes to heating and hot water. 2020 the most common energy source for heating these buildings was electricity (Energimyndigheten 2022). The energy prices have increased heavily during the last year. This ma
Bygg- och servicesektorn står idag för mer än en tredjedel av Sveriges totala energianvändning. Energifrågan ligger i fokus och samhället strävar efter en mer hållbar utveckling. Samtidigt ökar elpriserna vilket lämnar många hushåll med dyra räkningar för uppvärmning av sina småhus. En stor del av Sveriges småhus byggdes under 70-talet i samband med miljonprogrammet. Villabyggandet var som mest The construction and service sector currently accounts for over one-third of Sweden's total energy consumption. Energy issues are at the forefront, and society is striving for more sustainable development. At the same time, electricity prices are increasing, leaving many households with expensive bills for heating their houses. A significant portion of Sweden's houses were built during th
Tidewater glaciers on Svalbard are sensitive indicators of climate change and play a crucial role for Arctic ecosystems. The widespread retreat of tidewater glaciers across Svalbard highlights the need to quantify retreat rates and project when these glaciers will become land-terminating. This study investigates tidewater glacier retreat during historical (1936–1990) and present (2012–2024) period
Migration does have a time, energy or mortality cost, and the strategy to minimise the costs shapes the migration behaviour. Depending on the relative influence of these costs in shaping the migration, an animal is expected to undertake these journeys in different ways, depending on their morphology and migration ecology. I investigated if five Tringa-type waders minimise their migration time, and
Krig och konflikter världen över har lett till ett ökat intresse för och behov av försvar. Förhörssituationer har tidigare färgats av inhumana tillvägagångssätt och tortyr för att bryta motstånd hos den förhörde och få relevant information trots att tidigare forskning har visat att dessa metoder är ineffektiva. Denna studie syftade till att undersöka hur effektiv användning av olika förhörsteknikeWar and conflicts worldwide have increased both the interest in, and the need for defence. Historically, interrogation contexts have been characterized by inhumane approaches, such as torture, aimed at breaking resistance and obtaining information, despite previous research, demonstrating the ineffectiveness of such methods. The aim of this study was to examine how the effective use of different i
The construction and real estate sector is a major contributor to global carbon emissions and climate change. Ventilation systems, although essential for maintaining indoor air quality and occupant health, account for a significant share of building operational emissions. In HVAC systems, duct layouts significantly influence ventilation impacts through both the embodied carbon from material produc
There are a limited number of scientific studies concerned with the evaluation of DSS in general, and even less concerned with the evaluation of DSS in a clinical context. The purpose of this study is to evaluate the clinical DSS at the Department of Orthopedics at Sahlgrenska University Hospital in order to answer how one should evaluate clinical DSS. We have in our study created a research frame
Den 30 mars 2017 presenterade Finansdepartementet Vissa frågor inom fastighets- och stämpelskatteområdet (SOU 2017:27), även kallat paketeringsutredningen. Förslagen som utredningen presenterade innebär bland annat att transaktioner med paketerade fastigheter ska beskattas symmetriskt med lagfartsöverlåtelser, till skillnad från nuläget då de kan ske skattefritt genom försäljning av näringsbetingaOn March 30th 2017 the special appointed committee from the Swedish Treasury Department presented Vissa frågor inom fastighets- och stämpelskatteområdet (SOU 2017:27), also known as “paketeringsutredningen”. Suggestions from the public investigation include among other things amendments stating that transactions of incorporated real estate should be taxed symmetrically with traditionally transacti
Söderslätt has been dominated by agriculture since many centuries ago. About 90 % of the area is cultural land nowadays. The aim of this paper is to quantify recent changes of ecological relevance in Söderslätt. Interpreted aerial photos from 1938 and 1985 were digitised and geometrical corrected for the change study. The agrarian development since the 1940s has meant a continuos change from small
Patterns of transmigration emerging as a consequence of globalization are creating new and complex markets for communicative resources in which languages and language varieties are differently valued. In a Swedish context, where lingua franca English can facilitate communication but where monolingual norms prevail and Swedish is positioned as the key to 'integration', the purpose of this study is
