Today, "the digital library" is the common way of describing a managed collection of information, with associated services, stored in digital formats and accessible over a network. Digital libraries have mainly been developed at research libraries, but during the last few years public libraries have started to offer similar services. The aim of this Master's thesis is to study how t
The thesis deals with consumers behaviour in the use of online services and the cultures effect on it. It is a study of Swedes and Danes use of online job data bases. The thesis is based on a quantitative study. A questionnaire were used sent out to 80 Swedes and 80 Danes. The theory concerns areas of online consumer behaviour, decision making and services theory as well as theories within culture
Soil erosion has created landscape problems in many parts of the world and in particular in cold regions where the sensitive permafrost conditions have changed due to climate warming. Such a case occurred in the Tibetan Plateau (TP), which has been strongly affected by global warming and human activities. Monitoring technologies, like remote sensing and field surveys were used to explore soil eros
Late Quaternary glaciations, deglaciations, sea-level changes and aeolian activity have resulted in an abundance of clastic sediments that currently cover the three Baltic States, Northern Europe almost entirely. The chronology for these deposits has largely been established from luminescence dating. This review synthesises 201 luminescence ages obtained between 2011 and 2021 on sediments in the B
Wild insect pollinators are essential to cultivated and natural ecosystems globally. Today, many pollinator species are declining. One reason is a general lack of flowering habitats at landscape scales. However, urban areas, including private gardens, may provide flowers, and constitute beneficial habitats for pollinators. Here, we evaluate the ecological outcomes of a citizen science campaign run
Albert-László Barabási, from the introduction to his book titled Linked: the new science of networks, “Just as diverse humans share skeletons that are almost indistinguishable, we have learned that these diverse maps follow a common blueprint. A string of recent breathtaking discoveries has forced us to acknowledge that amazingly simple and far-reaching natural laws govern the structure and evolut
X-ray crystallography is the main source of atomistic information on the structure of proteins. Normal crystal structures are obtained as a compromise between the X-ray scattering data and a set of empirical restraints that ensure chemically reasonable bond lengths and angles. However, such restraints are not always available or accurate for nonstandard parts of the structure, for example substrat
Background & Aims: Few patients with primary sclerosing cholangitis (PSC) and inflammatory bowel diseases (IBDs) are exposed to tumor necrosis factor (TNF) antagonists because of the often mild symptoms of IBD. We assessed the effects of anti-TNF agents on liver function in patients with PSC and IBD, and their efficacy in treatment of IBD. Methods: We performed a retrospective analysis of 141
Objectives: Accurate and reliable diagnostics are crucial as histopathological type influ-ences selection of treatment in lung cancer. The aim of this study was to evaluate real-world accuracy and use of immunohistochemical (IHC) staining in lung cancer diagnostics. Materials and Methods: The diagnosis and used IHC stains for small specimens with lung cancer on follow-up resection were retrospecti
Understanding the emergence and development of coastal adaptations is a central theme in the archaeology of Maritime Northeast Asia. The capacity to harvest, store and share aquatic resources offered a novel economic strategy that could support greater sedentism and new forms of social life. In turn, growing reliance on the exploitation of rich coastal resources wouldhave generated powerful incent
The carotid-to-femoral pulse wave velocity, determined by pulse transit time (PTT) and distance, is a well-established measure of arterial stiffness and predicts adverse outcomes. However, its predictive value decreases with aging. To explore new risk indicator in the elderly, we investigated if the variation of carotid-to-femoral pulse wave velocity, registered as beat-to-beat variability of caro
The marine middle Burdigalian sediments of the North Alpine Foreland Basin (NAFB) or Molasse Basin are well known for abundant occurrences of benthic foraminifers and ostracods. However, taxonomic studies of ostracod assemblages are comparatively rare and, given its abundance, the group remains heavily understudied. Here we report a new, rich and well-preserved ostracod fauna from the middle Burdi
The analysis of DNA methylation has become an established method for chronological age estimation. This has triggered interest in the forensic community to develop new methods for age estimation from biological crime scene material. Various assays are available for age estimation from somatic tissues, the majority from blood. Age prediction from semen requires different DNA methylation markers and
Understanding N budgets of tundra ecosystems is crucial for projecting future changes in plant community composition, greenhouse gas balances and soil N stocks. Winter warming can lead to higher tundra winter nitrogen (N) mineralization rates, while summer warming may increase both growing season N mineralization and plant N demand. The undulating tundra landscape is inter-connected through water
The aim of the present study was to estimate the range of climate variability in Central Poland during the Eemian Interglacial (MIS 5e). High resolution pollen records are available for all seven RPAZs typical of this interglacial in Central Europe. These pollen records were used to estimate total annual precipitation and mean annual temperature, as well as the mean temperatures of the warmest and
Sedan mitten på 1900 talet har halvledarmaterial revolutionerat hur vi ser på världen genom uppfinningar som det har gett upphov till, såsom datorer, solceller, och lysdioder. Det är möjligheten att kunna styra halvledarens förmåga att leda ström—mellan att vara nästan metallisk till att vara isolerande—som gör den användbar för tillämpningar inom elektronik. Under de senaste decennierna har elektThis dissertation focus on the atomic-scale characterization of the surface properties and electronic structure of III–V semiconductor nanowires (NWs). Since the early 2000s, the fabrication and characterization of III–V NWs has been a very significant topic within material science due to their potential for applications in lighting, energy harvesting, and electronics. A prominent feature of the N
We used PCR and DNA sequencing to screen for haemosporidian parasites (Haemoproteus and Plasmodium) in 2,488 individual birds from 104 species and 22 families, primarily understory suboscine passerines, captured in a lowland Amazonian forest in Ecuador as a first major step to understanding the transmission dynamics of this cosmopolitan group of parasites in this region. To assess diversity of avi
Purpose: Although advances in Hodgkin lymphoma (HL) treatment have led to improved disease-free survival, this has been accompanied by an increased risk of second cancers. We sought to quantify the second cancer risks and to investigate the impact of family history. Patients and Methods: Using the Swedish Family-Cancer Project Database, we identified 9,522 individuals with primary HL diagnosed bet
