At low temperature, cell membrane functionality depends on adjustments of membrane phospholipid fatty acid (PLFA) composition. We here test the hypothesis that previous exposure to copper (Cu) may deteriorate tolerance to freezing temperatures because of Cu-induced changes of PLFA composition of cell membranes in the freeze-tolerant earthworm Dendrobaena octaedra. Cu levels and freezing temperatur

This thesis presents a study on performance analysis and optimal design of heat exchangers and heat exchanger networks. The study includes an experimental investigation of steam condensation in plate heat exchangers, optimal design of plate heat exchangers and plate-fin heat exchangers, and optimization of heat exchanger networks. In the experimental investigation of steam condensation in plate h

Popular Abstract in Swedish Betydelsen av fysiskt kapital är något som ofta understryks i allmänna ordalag i den ekonomisk-historiska litteraturen. Väldigt få undersökningar har däremot försökt att kvantifiera och analysera det fysiska kapitalets betydelse för ekonomisk tillväxt under den svenska industrialiseringsprocessen. Det gäller i synnerhet på branschnivå. En sådan studie genomförs därför iThe significance of physical capital is often mentioned in general terms in economic history literature. In this study the amount of physical capital is calculated and its significance for industrial growth is analysed for the period 1870-1930. The largest and most important part of this thesis consists of constructions of capital stocks for industry as a whole and on the branch level. These cons

UNLABELLED: To clarify the role of the TNFRSF11B gene encoding osteoprotegerin (OPG), in Paget's disease of bone (PDB) we studied TNFRSF11B polymorphisms in an association study of 690 UK subjects and in a worldwide familial study of 66 kindreds. We found that the G1181 allele of TNFRSF11B, encoding lysine at codon 3 of the OPG protein, predisposes to both sporadic and familial PDB.INTRODUCTION: P

BACKGROUND AND PURPOSE: An increasing number of radiotherapy centres is now aiming for clinical implementation of intensity modulated radiotherapy (IMRT), but--in contrast to conventional treatment--no national or international guidelines for commissioning of the treatment planning system (TPS) and acceptance tests of treatment equipment have yet been developed. This paper bundles the experience o

The close linkage between iron (Fe) and phosphorus (P) suggests that changes in Fe speciation may have a strong effect on the bioavailability of P. At the same time Fe speciation in natural oxic environments is known to be affected by the presence of organic matter (OM), pH and total Fe concentrations, thus these parameters should also influence the Fe-P interactions. The main objective of the pre

Kisel är ett vanligt förekommande grundämne som gärna bildar en oxid, nämligen kiseldioxid. Kiseldioxid träffar man i hög utsträckning på i det dagliga livet. Det är nämligen huvudbeståndsdelen i sand, glasvaror, kvarts, många keramiska material men också i den färgskiftande ädelstenen opal. Det finns också flera grupper av porösa kiseldioxidmaterial, till exempel så kallade zeoliter som har myckeThe formation process of porous silica materials is an intricate process, involving a number of components that interact to form a highly organized material. Both zeolites and mesoporous silica materials typically require the presence of organic structure director agents (SDAs) around which the silica network polymerizes. For zeolites the SDAs are molecular and for mesoporous silica the SDAs assem

Bromide anations of PtBr5H2O− in the presence of PtBr42− or bromine, of trans-PtBr4(H2O)2 in the presence of PtBr42− and of cis-PtBr4(H2O)2 in the presence of bromine have been studied in 0.50 M perchloric acid medium at 25 °C. The rate law for the bromide anation of PtBr5H2O−indicates two parallel reaction paths. The term k′Br−2 corresponds to a bromide assisted mechanism. The second term i

Cases of successful developmental states constrained by democratic institutions pose challenges to the literature on the political economy of late development. On the one hand, the dominant view is that successful developmental states tend to rely on authority-based coordination mechanisms—corporatist arrangements, labor repression, professional bureaucracies insulated from popular pressures—to soCases of successful developmental states constrained by democratic institutions pose challenges to the literature on the political economy of late development.

The study describes findings from a community-based participatory and challenge-driven research programme, that aimed to improve health equity through a health promotion platform in an ethnically diverse low-income neighbourhood of Malmo, Sweden. Local residents, together with lay health promoters living in the area, were actively involved in the planning phase and decided on the structure and con

Although COVID-19 was first detected in the People’s Republic of China, the pandemic now appears contained there. Western and Chinese media attribute this apparent success to the central level of the Chinese state and the Communist Party. However, this article reveals that local entities provided critical contributions to China’s COVID-19 management, particularly in the pandemic’s first epicenter:

AbstractObjectives: Patients with inflammatory rheumatic diseases (IRDs) have higher risk of serious infections than healthy individuals due to their illness, comorbidities and treatments. Streptococcus pneumoniae is responsible for 30-50% of community aquired pneumonia in Europe.The proportion of patients with IRD receiving vaccination against pneumococci is still estimated to be suboptimal. The

Introduction: Uncertainty in the dose-response of low dose radiation raised concern of an increased cancer incidence in Sweden after the Chernobyl Nuclear Power Plant (NPP) accident. Material and methods: A closed cohort was created of all males ≥18 years of age living in the Northern Sweden in 1986. In total 826,400 individuals were enrolled including 40,874 hunters. A nested case-control design

Background and Aims: Substance use disorder (SUD) is related to widespread adverse consequences, including higher suicidality. Shared genetic liability has been demonstrated between SUD and suicidality. Here, we measured the factors that contribute to increased risk of non-fatal suicide attempt among individuals with SUD by focusing upon aggregate genetic risks and both childhood and past-year env
