Reconstructions of the geomagnetic field in the past represent a useful tool not only to investigate the geodynamo process, but also to estimate the effect of geomagnetic shielding for any studies on cosmogenic radionuclides and galactic cosmic rays. A number of new millennial-scale geomagnetic field reconstructions have been published over the last years, based on improved global archeo- and pale
We extend a newly introduced framework for the simulation of shape memory alloys undergoing martensite-austenite phase-transformations by allowing for the evolution of individual plastic deformations in each phase considered. The goal is to obtain a generalised model which will facilitate the reflection of the characteristic macroscopic behaviour of SMA as well as TRIP steels. Particularly, we sho
Myoepithelioma, mixed tumor and parachordoma are uncommon soft tissue tumors thought to represent morphological variants of a single tumor type. The genetic basis of these neoplasms is poorly understood. However, they morphologically resemble mixed tumor of the salivary glands (also known as pleomorphic adenoma), a tumor characterized by deregulated expression of PLAG1 or HMGA2. To evaluate a poss
Context: The questions of how many individuals and how much time to use for a single testing task are critical in software verification and validation. In software review and usability evaluation contexts, positive effects of using multiple individuals for a task have been found, but software testing has not been studied from this viewpoint. Objective: We study how adding individuals and imposing
Background: A large number of gene expression profiling (GEP) studies on prognosis of colorectal cancer (CRC) has been performed, but no reliable gene signature for prediction of CRC prognosis has been found. Bioinformatic enrichment tools are a powerful approach to identify biological processes in high-throughput data analysis. Principal Findings: We have for the first time collected the results
BACKGROUND: There are two principal types of group O alleles; deletional alleles feature 261delG leading to nonfunctional truncated protein. Nondeletional alleles have the consensus guanosine at residue 261. The major nondeletional allele, O-2, encodes full-length protein with Gly268Arg. While reports vary, O-2 has been proposed to encode weakly functional A-glycosyltransferase (GTA). The main obj
Temperate calcareous grasslands are characterized by high levels of species richness at small spatial scales. Nevertheless, many species from a habitat-specific regional species pool may be absent from local communities and represent the dark diversity' of these sites. Here we investigate dry calcareous grasslands in northern Europe to determine what proportion of the habitat-specific species pool
Popular Abstract in Swedish Blodlevring är en samlingsterm för en serie reaktioner som medför att blod omvandlas från vätska till en geléliknande massa. I koagulationsprocessen samverkar de minsta cellerna i blodet, trombocyterna (blodplättarna), med ett stort antal blodproteiner. Koagulationens viktigaste uppgift är att stoppa blödningar som uppkommer vid skador på blodkärlen. Central venkateteBleeding complications range from 0.5 to 1.6% in connection with central venous catheter insertions but are more frequent in patients with bone marrow failure and severe thrombocytopenia. Although supportive evidence is scarce, prophylactic platelet transfusion is sometimes performed in these patients before catheter insertion. Furthermore, the ideal threshold platelet count and timing of transfus
Radial velocities measured from near-infrared (NIR) spectra are a potentially powerful tool to search for planets around cool stars and sub-stellar objects. However, no technique currently exists that yields NIR radial velocity precision comparable to that routinely obtained in the visible. We are carrying out an NIR radial velocity planet search program targeting a sample of the lowest-mass M dwa
Popular Abstract in Swedish Hela livscykeln för en elektronikvara är förknippad med miljöpåverkan. I jämförelse med många andra varor är tillverkningen av elektronik och i synnerhet halvledarkomponenter mycket resurskrävande. Elektroniken ger också upphov till ett antal mycket giftiga utsläpp och avfallsströmmar, såväl från själva tillverkningen som från de uttjänta varorna. Elektronikindustrin haThe life cycle of electronic products is associated with significant environmental impacts. Compared to many other products, the production of electronics and in particular semiconductors is resource intensive and generates a number of highly toxic waste streams in manufacturing and post-consumer stages of product life cycle. Electronics manufacturing industry has been successful in reducing envir
High-dose exposure to inorganic mercury in man can influence the immune system and in rare cases cause immune-related disease. Some experimental animals also react with autoimmunity after low doses of inorganic mercury. Glomerulonephritis and an increased formation of immunoglobulin type E (IgE) are characteristic of these reactions. A recent study of 15-year-old adolescents demonstrated an associ
Background: Swedish studies on antibiotic use in primary care have been based on one-week registrations of infections. In order to study adherence to guidelines, analyses based on large databases that provide information on diagnosis linked prescriptions, are needed. This study describes trends in management of infections in Swedish primary care particularly with regards to antibiotic prescribing
The book provides a thorough legal analysis of the treatment of insurance in the harmonized system of European VAT as compared to the treatment of insurance in the New Zealand and Australian Goods and Services Tax (GST) systems. Insurance constitutes a significant part of the financial services sector, and it is one of the foundations of a modern society and economy. In the design of tax laws, how
Thin films of "complex salts" (CS = ionic surfactants with polymeric counterions) have recently been shown to respond to humidity changes in ambient air by changing their liquid crystalline structure. We here report isotherms and kinetics of water sorption/desorption for ∼10-100 μm films of alkyltrimethylammonium polyacrylate CS, measured in a dynamic gravimetric vapor sorption instrument over a 0
Amylin, a pancreatic β-cell-derived peptide hormone, forms inclusions in brain microvessels of patients with dementia who have been diagnosed with type 2 diabetes and Alzheimer's disease. The cellular localization of these inclusions and the consequences thereof are not yet known. Using immunohistochemical staining of hippocampus and parahippocampal cortex from patients with Alzheimer's disease an
Cell replacement therapy in Parkinson’s disease (PD) still lacks a study addressing the acquisition of electrophysiological properties of human grafted neural stem cells and their relation with the emergence of behavioral recovery after transplantation in the short term. Here we study the electrophysiological and biochemical profiles of two ventral mesencephalic human neural stem cell (NSC) clonal
The discovery of reliable biomarkers to predict efficacy and toxicity of anticancer drugs remains one of the key challenges in cancer research. Despite its relevance, no efficient study designs to identify promising candidate biomarkers have been established. This has led to the proliferation of a myriad of exploratory studies using dissimilar strategies, most of which fail to identify any promisi
The exploration of exotic nuclei is one of the most intriguing and fastest expanding fields in modern nuclear physics. In the extreme conditions of unsymmetric neutron-proton distributions and small binding energies many nuclear phenomena not encountered closer to stability have revealed themselves, often as a surprise to the nuclear physics community, the prime example being the development of ha
