Why is current capitalism unwilling (or unable) to shift its energy base from fossil fuels to renewable energy? Explanations such as information deficit, socially organized denials, or game-theoretical dilemmas are insufficient. Neither are the obstacles primarily technical or financial. Rather, the problems are related to social relations and capitalism as such. Four potential barriers to a renew
We study here deterministic broadcasting in geometric radio networks (GRN) whose nodes have complete knowledge of the network. Nodes of a GRN are deployed in the Euclidean plane (R 2) and each of them can transmit within some range r assigned to it. We adopt model in which ranges of nodes are non-uniform and they are drawn from the predefined interval 0 ≤ r min ≤ r max . All our results are in th
Energy consumption reduction is today an important design issue for all kinds of digital systems. Offering both flexibility and efficient energy management, variable speed processor architectures are prefered for low energy consumption even in hard real-time systems. For this type of systems, the main approach consists in trading speed for lower energy while meeting all deadlines. For tasks with v
Four years have passed since January 1996 when retail competition was introduced in the Swedish electricity market. These years have been characterized by a rapid restructuring of the electricity supply industry through mergers and acquisitions, lower electricity prices, and a search for new marketing strategies in the competitive market. General trends and the results of two market surveys, under
The purpose of this study was testing and performance simulation of an innovative tracking hybrid solar system being developed by the Swedish Company Arontis. The Solar8 collector produces both electrical and thermal energy in one system. Its performance was compared with conventional photovoltaic panels and solar thermal collectors working side-by-side which are already on the market. The solar8
Recent studies indicate a crucial role for neuronal glycogen storage and degradation in memory formation. We have previously identified alpha-amylase (α-amylase), a glycogen degradation enzyme, located within synaptic-like structures in CA1 pyramidal neurons and shown that individuals with a high copy number variation of α-amylase perform better on the episodic memory test. We reported that neuron
Ambient fine particulate matter PM2.5 (particles with a diameter smaller than 2.5 μm) has been associated with cardiovascular and respiratory morbidity and mortality. It has been shown that biomass burning for heat production purposes can generate large amounts of fine particles. Thus characteristics of particle emissions from biofuel combustion may be important in the assessment of health effects

OBJECTIVE: In Sweden, a country with high standards of obstetric care, the high rate of perinatal mortality among children of immigrant women from the Horn of Africa raises the question of whether there is an association between female circumcision and perinatal death. METHODS: To investigate this, we examined a cohort of 63 perinatal deaths of infants born in Sweden over the period 1990–96 to cir
Background. This case-control study was performed to evaluate whether adding first-trimester maternal serum testing to nuchal translucency measurement would improve the antenatal detection of Down's syndrome and decrease the number of women offered fetal karyotyping. Methods. In the Swedish Nuchal Translucency Trial 39,572 pregnant women were randomized to a routine scan at 12-14 gestational weeks
Background: Mild traumatic brain injury (TBI) is associated with substantial costs due to over-triage of patients to computed tomography (CT) scanning, despite validated decision rules. Serum biomarker S100B has shown promise for safely omitting CT scans but the economic impact from clinical use has never been reported. In 2007, S100B was adapted into the existing Scandinavian management guideline
The role of glial cells in the pathogenesis of many neurodegenerative conditions of the central nervous system (CNS) is now well established (as is discussed in other reviews in this special issue of Frontiers in Neuropharmacology). What is less clear is whether there are changes in these same cells in terms of their behavior and function in response to invasive experimental therapeutic interventi
Background: Identification of disease-associated single nucleotide polymorphisms (SNPs) in seasonal allergic rhinitis (SAR) may be facilitated by focusing on genes in a disease-associated pathway. Objective: To search for SNPs in genes that belong to the T-cell receptor (TCR) pathway and that change in expression in allergen-challenged CD4+ cells from patients with SAR. Methods: CD4+ cells from pa
Populärvetenskaplig sammanfattning Ska du flyga långt med de där vingarna? Vissa fåglar flyger långt, andra inte. Silvertärnorna flaxar med vingarna från Arktis till Antarktis medan pingvinerna använder vingarna för att simma och inte flyger alls. Eftersom att olika fåglar använder sina vingar på så olika sätt så har nämnda vingar anpassats efter vingbärarnas behov. Vissa studier har visat sambaAbstract Bird wings are adapted to the needs of the birds and bird wings therefore differ between species, but also between ages and sexes. In this thesis, an interspecific analysis investigating relations between measurements of wing shape for birds within the Sylviidae-family, revealed strong connections between morphologically unrelated measurements. Long distances (compared to the wing length
Background: The pathogenesis of COPD is complex and remains poorly understood. The European Respiratory Society Study on Chronic Obstructive Pulmonary Disease (EUROSCOP) investigated long-term effects of budesonide; 18% of the COPD participants were atopic. So far effects of atopy on the long-term course of COPD have not been elucidated. Methods: Factors related to the presence of atopy (positive
HAMLET (human alpha-lactalbumin made lethal to tumor cells) interacts with multiple tumor cell compartments, affecting cell morphology, metabolism, proteasome function, chromatin structure and viability. This study investigated if these diverse effects of HAMLET might be caused, in part, by a direct effect on the ATP synthase and a resulting reduction in cellular ATP levels. A dose-dependent reduc
