Popular Abstract in Swedish Glas kan användas för retrospektiva radon mätningar på grund av radondöttrars förmåga att implantera i glasets översta skikt. Mängden implanterad aktivitet blir lätt påverkad av en rad olika faktorer i den omgivande luften. Experimentella metoder har därför utvecklats för att bestämma djupfördelningen av alfarekyl-implanterat 210Po i glas. Detta göres genom gradvis etsnGlass sheets are often used in radon surveys to estimate retrospective radon concentrations, as radon progenies are embedded in the upper surface layer. The implanted activity is influenced by a variety of different environmental conditions. In this work, experimental methods based on etching to determine the depth distribution of recoil-implanted 210Po in glass from radon decay in air were develo

The present study aimed to investigate how the impact of several factors linked to geography would shape life-history traits in a gregarious species, using the pine processionary moth (PPM) Thaumetopoea pityocampa as a model system. PPM has a wide geographical distribution over the Mediterranean Basin, and it is a strictly gregarious species throughout larval development, where the total reproduct

BACKGROUND: The need for equivalent results of routine measurement procedures for the alcohol biomarker carbohydrate-deficient transferrin (CDT) has been recognized by the IFCC. This article describes a project to harmonize CDT as conducted by an IFCC working group initiated for this purpose. METHODS: We used procedures for achieving harmonization as developed by the Consortium for Harmonization o

OBJECTIVES: Stroke is a serious complication in patients with acute type A aortic dissection (ATAAD). Previous studies investigating stroke in ATAAD patients have been limited by small cohorts and have shown diverging results. We sought to identify risk factors for stroke and to evaluate the effect of stroke on outcomes in surgical ATAAD patients. METHODS: The Nordic Consortium for Acute Type A Ao

Global warming increasingly challenges thermoregulation in endothermic animals, particularly in hot and dry environments where low water availability and high temperature increase the risk of hyperthermia. In birds, un-feathered body parts such as the head and bill work as ‘thermal windows’, because heat flux is higher compared to more insulated body regions. We studied how such structures were us

In this paper we study the Lilang Super Group in the Spiti area, Indian Himalaya to understand environmental changes in the aftermath of the end-Permian mass extinction. We focus on the Mikin and Kaga Formations, which span the Induan to Ladinian stages of the Lower and Middle Triassic. These strata formed on the southern mid-palaeolatitude margin of East Gondwana and are interpreted as condensed,

Background: It is currently estimated that one third of all children will sustain fractures. However, there may also be time trends in pediatric fracture incidence. When predicting future fracture incidence, it is further important to evaluate bone mass, as low bone mass is a strong predictor of fractures. Such evaluation would help the society to allocate health care resources adequately. Aims: T

Rhenium(I)-carbonyl-diimine complexes have emerged as promising photocatalysts for carbon dioxide reduction with covalent organic frameworks recognized as perfect sensitizers and scaffold support. Such Re complexes/covalent organic frameworks hybrid catalysts have demonstrated high carbon dioxide reduction activities but with strong excitation energy-dependence. In this paper, we rationalize this

Since spring 2019 an experimental setup consisting of an electron spectrometer and an ion time-of-flight mass spectrometer for diluted samples has been available for users at the FinEstBeAMS beamline of the MAX IV Laboratory in Lund, Sweden. The setup enables users to study the interaction of atoms, molecules, (molecular) microclusters and nanoparticles with short-wavelength (vacuum ultraviolet an

Objective: Different hypothalamic-pituitary-adrenal (HPA) axis function tests are used for diagnosing disease and evaluating suppressive effects of corticosteroid treatment. Our objectives were to evaluate sensitivity and precision of different HPA axis tests to be able to select one that combines good performance with good practicability, suitable for investigation of new corticosteroids in clini

Popular Abstract in Swedish I vår egen tid finns ett stort intresse för släktforskning och historia hos många. Men man tänker sällan på att även människor i gångna tider kunnat blicka tillbaka på sitt förflutna och fundera på sin egen plats i släktleden. Vad var de ville minnas och hur mindes de i en tid utan skriv- och läskunnighet? Det är frågor som ställs i avhandlingen och där svaren söks i deThis thesis examine how farm-dwellers in the Mälaren region during the late Iron Age and early Middle Ages created, transferred, and preserved memory by deliberately placing new houses and graves on the houses and graves of previous generations. Focus is on memory as a social phenomenon and culture-specific resource created by these deliberate practices. The culture-specific element is oral cultur

A combined search for the Standard Model Higgs boson with the ATLAS experiment at the LHC using datasets corresponding to integrated luminosities from 1.04 fb(-1) to 4.9 fb(-1) of pp collisions collected at root s = 7 TeV is presented. The Higgs boson mass ranges 112.9-115.5 GeV, 131-238 GeV and 251-466 GeV are excluded at the 95% confidence level (CL), while the range 124-519 GeV is expected to b

The relationship between field measurements of vegetation in a semi arid region and NDVI from the 1 km NOAA AVHRR was investigated within this study. The Hoanib catchment in the northwestern Namibia was chosen as study area. The field measurements were carried out during the month of February 1999. Different NDVI values and combinations of NDVI were used and it was found that the integrated NDVI u

Intellectual property is a very important type of asset in today’s business world. Since business in the Western World grows increasingly based and dependent on know-how and technological development, intangible assets such as trademarks, copyrights and patents plausibly represent greater economic value to economic actors here than other, physical, assets do. Although it is comparatively unknown

Den iranska staden Bam drabbades av en kraftig och ödesdiger jordbävning den 26 december 2003 som resulterade i att hela staden ödelades och tiotusentals av stadens invånare omkom. Det faktum att jordbävningen inträffade 05.26 på morgonen i kombination med traditionellt byggda bostadshus med lera som huvudmaterial var de främsta anledningarna till den höga dödssiffran och förstörelsen i staden. Ok

The Antikythera Wreck represents a unique example of implementation and development of technological methods and systems aiding archaeological research. Since 1900, when the wreck was discovered, the challenges posed by the underwater environment and the variety of archaeological data hidden in the multifarious artifacts has been yielding great opportunities for technological innovation.
