Drawing from Swedish press history in the eighteenth and nineteenth centuries, the present article argues for further historical investigation into three aspects of Jürgen Habermas’ theory of the public sphere. The first concerns actual media participation, the second the representative features of media institutions, and the third media systems. These routes of analysis can and should be combined

This paper offers a positive identification of Sahl ibn Bishr’s Kitāb al-ʾaḥkām ʿalā ʾn-niṣba al-falakiyya as the Arabic source text for what is perhaps the most characteristic feature of the medieval Perso-Indian style of astrology known as tājika: the sixteen yogas or types of planetary configurations. The dependence of two late sixteenth-century tājika works in Sanskrit – Nīlakaṇṭha’s Tājikanīl

The aim of this study was to demonstrate safe orthotopic transplantation of porcine donor hearts harvested 24 hours after brain death and preserved for 24 hours before transplantation.

The article aims at making visible new orders of encyclopaedic knowledge by means of an ethnographic study carried out during eight months at the editorial office of the leading commercial encyclopaedia in Sweden, Nationalencyklopedin. The investigation is framed in a socio-technical understanding of how people, technologies and practices relate to each other. Three themes were identified during t

Appearance of dyskinesia is a common problem of long-term Levodopa (L-DOPA) treatment in Parkinson's disease (PD) patients and represents a major limitation for the pharmacological management of the motor symptoms in the advanced stages of disease. An increasing body of evidence points to dopamine released as a false neurotransmitter from the striatal serotonin terminals as the main pre-synaptic d

Appreciation and production of musical rhythm is a human universal and, as with other human capacities, it is imperative to understand the extent of our capacity to perceive and produce rhythm. This thesis presents my work on the cognitive and perceptual aspects of rhythm perception and production at a slow tempi. In Paper I I establish that rhythm production, such as keeping the beat to a metron

Photosynthetic light harvesting in excess light is regulated by a process known as feedback deexcitation. Femtosecond transient absorption measurements on thylakoid membranes show selective formation of a carotenoid radical cation upon excitation of chlorophyll under conditions of maximum, steady-state feedback deexcitation. Studies on transgenic Arabidopsis thaliana plants confirmed that this car

Introduction. We present a prototype collaboratory, a socio-technical platform to support sharing research data collection instruments in library and information science. No previous collaboratory has attempted to facilitate sharing digital research data collection instruments among library and information science researchers. Method. We have taken a socio-technical approach to design, which inclu

Abstract In a 3-year-old boy, a continuous heart murmur was heard. The echocardiogram showed a dilated right coronary artery suggesting the existence of a coronary fistula. A more detailed echocardiogram when the patient was sedated revealed a fistula leading to a large aneurysm and further to the right atrium. The accidental dissection and thrombosis during the interventional heart catheterizatio

Vascular aging is described as a gradual process involving biochemical, enzymatic, and cellular changes of the vasculature and modification of the signals that modulate them. On the basis of this conception a new pathophysiological model for deeper understanding of cardiovascular risk and its treatment was introduced. The idea of early vascular aging, that is the acceleration of vascular aging see

Popular Abstract in Swedish Sedan människan lyckades skapa eld har förbränning utgjort den viktigaste energikällan i mänsklighetens långa historia, viket den ser ut att fortsätta vara det inom en överskådlig framtid. I dagsläget kommer mer än 90% av vår energi från förbränningsprocesser. Dock uppstår en rad problem kring förbränning, såsom föroreningar och möjligheten till använda sig av förnyelseNowadays, more than 90% of our energy comes from combustion processes. Hence, it is very important to perform combustion research to reduce emissions, improve efficiency, find clean and renewable fuels, strengthen safety, etc. The complexity of combustion processes asks for advanced diagnostic tools, among which the laser spectroscopy has been proved to be a powerful one. This thesis is about the
