Patterns of genetic diversity have previously been shown to mirror geography on a global scale and within continents and individual countries. Using genome-wide SNP data on 5174 Swedes with extensive geographical coverage, we analyzed the genetic structure of the Swedish population. We observed strong differences between the far northern counties and the remaining counties. The population of Dalar
Background: Patients living under better socioeconomic circumstances often receive more active treatments after an acute myocardial infarction ( AMI) compared to less affluent patients. However, most previous studies were performed in countries with less comprehensive coverage for medical services. In this Swedish nation- wide longitudinal study we wanted to evaluate long- term survival after AMI
Purpose - The purpose of this paper is to explore how a global supplier network can support and contribute to a market driving strategy. Theoretically, the paper contributes by integrating the market driving strategy and the network approach. IKEA is considered one of the leading market driving firms. The paper studies its activities in establishing supplier networks in Russia and Poland. Design/m
We present experiments in which the interaction of a single gold nanoparticle with glass substrates or with another gold particle can be tuned by in situ control of their separations using scanning probe technology. We record the plasmon resonances of the coupled systems as a function of the polarization of the incident field and the particle position. The distinct spectral changes of the scattere
Oxy-fuel combustion is one of the proposed technologies which have the potential to achieve zero CO2 emission. Strontium cobalt based perovskite oxygen carriers are promising materials for air separation with a high selectively for oxygen. And these perovskites can produce an oxygen enriched carbon dioxide stream for an oxy-fuel combustion process. The relatively low oxygen production yield may be
Serum adiponectin is a risk factor for fracture. The predictive value attenuates with time in elderly men so that its use for the risk assessment in the long term is questionable. The study underlines the importance of testing the long-term stability of potential risk factors. High serum adiponectin is associated with an increased risk of fracture in elderly men. The aim of the present study was t
1-Butanoyl-2-palmitoyl phosphatidylcholine was synthesized from dipalmitoylphosphatidylcholine (DPPC) and butyric acid using a lipase catalyzed transesterification in toluene at controlled water activity. A high fatty acid concentration and low water activity were essential for the enzymatic synthesis. The transesterification resulted in 97.3% incorporation of butyric acid in the sn-1 position wit
Popular AbstractAvhandlingen undersöker sociokulturell och lingvistisk utveckling i det förkolumbianska Amazonområdet, med särskild fokus på perioden 500 f.Kr. till år 1500. Genom att sammanföra och analysera data från arkeologi, lingvistik, etnohistoria, etnografi och geografi i ett Geografiskt Informationssystem (G.I.S.) syntetiserar den stora mängder empiriska data från flera fält för att underThis thesis investigates the socio-cultural and linguistic development of pre-Columbian Amazonia, with a particular focus on the period between 500 BC and AD 1500. In assembling and analyzing data from archaeology, linguistics, ethnohistory, ethnography, and geography in a Geographical Information System (G.I.S.), it synthesizes large amounts of empirical data from several fields to facilitate lon

Aims: To assess changes in access to highly active antiretroviral therapy (HAART) between the end of 2002 and the end of 2005, and to review the capacity for further HAART scale-up in the then 52 Member States of the WHO European Region. Methods: Analysis of data from four surveys evaluating access to HAART, supplemented by regional estimates of the number of people receiving HAART. Changes in acc
Streptococcus pneumoniae serotype 3 strains are highly resistant to opsonophagocytosis due to recruitment of the complement inhibitor Factor H via Hic, a member of the pneumococcal surface protein C (PspC) family. In this study, we demonstrated that Hic also interacts with vitronectin, a fluid-phase regulator involved in haemostasis, angiogenesis, and the terminal complement cascade as well as a c
The purpose of this study is to describe how the greenhouse gas (GHG) benefits of ethanol from agricultural crops depend on local conditions and calculation methods. The focus is mainly on the fuels used in the ethanol process and biogenic GHG from the soils cultivated. To ensure that "good" ethanol is produced, with reference to GHG benefits, the following demands must be met: (i) ethanol plants
This study shows that different species of the same genus can behave differently in relation to a salinity gradient and suggests that a halocline can act as a barrier to the diel vertical migration (DVM) of dinoflagellate species. In a laboratory study, we found that the dinoflagellates Ceratium furca, C. tripos and Dinophysis acuta did not cross a salinity gradient of 5 psu, but instead exhibited
We report on magnetotransport measurements of nanoconstricted (Ga,Mn)As devices showing very large resistance changes that can be controlled by both an electric and a magnetic field. Based on the bias voltage and temperature dependent measurements down to the millikelvin range we compare the models currently used to describe transport through (Ga,Mn)As nanoconstrictions. We provide an explanation
This paper presents RF as well as low-frequency capacitance–voltage (C–V) characterization of vertical wrap-gated InAs/high-κ nanowire MOS capacitors. A full equivalent circuit model for traps is used to fit the low-frequency C–V characteristics, from which the interface trap density (Dit) and border trap density (Nbt) are evaluated separately. The results show comparable Nbt but far lower Dit (<1
BACKGROUND AND PURPOSE: Malunion after a distal radius fracture can be treated with an osteotomy of the distal radius. Often autologous iliac crest bone graft is used to fill the gap, but this is associated with donor site morbidity. Instead of bone graft, we have used a slow-resorbing bone substitute in combination with a minimally invasive fixation technique. PATIENTS AND METHODS: 25 consecutive
