Research on media and democracy mobilizes a range of conceptual versions of the subject. This is often done implicitly, or out of habit, with a specific model becoming established in any given research tradition. This presentation argues that different theories of the subject can have different implications for our understanding of citizenship and democracy. The text surveys a number of versions,

Popular Abstract in Swedish Intubationer (nedsättande av andningsslang i luftstrupen) i samband med generella anestesier kan påverka lungfunktionen med en sänkt arteriell syresättning (SpO2) som följd. Medel för inhalationsanestesi administreras och elimineras via andningsvägarna. Anestesimedlen tas upp i blodet från lungans alveoler genom diffusion och transporteras löst i blodplasma till hjärnanBackground and objective: General anaesthesia impairs respiratory function. The present studies were performed to compare arterial concentration of sevoflurane, oxygen and carbon dioxide in normal and overweight patients ventilated with increased tidal volume (VT), or normal tidal volume with and without PEEP. Methods: Prospective, randomised, clinical studies. ASA І and II abdominal surgery patie

We report here on the last progresses made with the PHOENIX electron cyclotron resonance charge breeder test bench at ISOLDE. Recently, an experiment was performed to test the trapping of 61Fe daughter nuclides from the decay of 61Mn nuclides. Preliminary results are given.

Artikeln presenterar två kvalitativa studier som fokuserat barns användning av och relation till platser utomhus utifrån barns perspektiv. Studierna genomfördes vid olika tidpunkter, i mitten av 1990-talet och under åren 2008–2009, med barn i ungefär samma åldrar (9–11 år), med liknande metoder och i snarlika typer av bostadsmiljöer, men i två olika svenska städer. Teoretiska utgångspunkter hämtas

Neutrophil-mediated lung injury is an insidious feature in sepsis although the mechanisms regulating pulmonary recruitment of neutrophils remain elusive. Here, we investigated the role of P-selectin glycoprotein-ligand-1 (PSGL-1) in sepsis-induced neutrophil recruitment and tissue injury in the lung. Bronchoalveolar infiltration of neutrophils, levels of myeloperoxidase, oedema formation and CXC c

This report presents a large number of optimal PI and PID parameters for a batch of 134 benchmark process models representative for the process industry. This information can e.g. be used as a reference for other controller design methods. The optimal parameters have been derived using the MATLAB®-based software called SWORD, which determines the PI or PID controller that gives the best load distu

The structures and dynamics of unsteady laminar partially premixed methane/air Bunsen flames are studied by means of numerical simulations, OH and CH PLIF imaging, and high speed chemiluminescence imaging employing a high framing speed intensified charge coupled device camera. The Bunsen burner has a diameter of 22 mm. Rich methane/air mixtures with an equivalence ratio of 1.5 are injected from th

In this article we analyze the equity and distribution of financial incentives in Ecuador's Programa Socio Bosque (PSB). PSB aims to conserve native ecosystems on privately owned lands while reducing rural poverty. Based on the analysis of 1,563 conservation contracts, representing nearly 900,000ha of land in Ecuador and more than 90,000 beneficiaries, we scrutinize the regional distribution of be

Despite a large and multifaceted effort to understand the vast landscape of phenotypic data, their current form inhibits productive data analysis. The lack of a community-wide, consensus-based, human- and machine-interpretable language for describing phenotypes and their genomic and environmental contexts is perhaps the most pressing scientific bottleneck to integration across many key fields in b

We report the characterization of three novel human papillomavirus (HPV) types of the genus Gammapapillomavirus. HPV175 and HPV180 were isolated from a condyloma. HPV178 was isolated from healthy skin adjacent to an actinic keratosis.

Simultaneous two-species imaging using single-shot planar laser-induced fluorescence have been performed to record high quality image pairs of CH/OH, CH/CH2O and OH/CH2O to visualize the flame front structures in swirl-stabilized lean premixed methane/air flames. The results show that the investigated flames exhibit various flame front structures distinctly in space, which covers: (1) the corrugat

Recent studies have identified mutations in the complement regulatory gene factor I (CFI) that predispose to atypical hemolytic uremic syndrome (aHUS). CFI is a two-chain serine protease in which the light chain carries the catalytic domain while the heavy chain's function is unclear. It downregulates the alternative and classical complement pathways by cleaving the alpha' chains of C3b and C4b in

The use of business excellence models (BEM) has become popular in the last two decades, and several companies have learned how to use them and gained from such models. More companies, we assume, have experienced problems when using such models because of various weaknesses such as too-sophisticated assessment criteria, excessive paperwork, cumbersome procedures and a lack of focus, which have limi

Background: The relative contribution to gastric cancer (GC) risk of variants in genes that determine the inflammatory response remains mostly unknown and results from genotyping studies are inconsistent. Patients and methods: A nested case-control study within the prospective European Prospective Investigation into Cancer and Nutrition cohort was carried out, including 248 gastric adenocarcinomas

The formation of aluminides during the heating of Nb-Al powder mixtures with different initial compositions (25, 33.3 and 75 at.% Al) has been studied using a differential scanning calorimeter. The effect of parameters like particle size, compaction and heating rate on the onset temperature of reaction has been determined. The results show that an increase in heating rate leads to an increase in o

The Hollow Rock Shelter site in Western Cape Province, South Africa, was excavated in 1993 and 2008. This study presents new results from a technological analysis of Still Bay points and bifacial flakes from the site. The results show that Still Bay points from the site are standardized tools. The points in the assemblage consist of a complex mixture of whole and fragmented points in all phases of

Vehicle-to-Vehicle (V2V) communication is a challenging but fast growing technology that has potential to enhance traffic safety and efficiency. It can also provide environmental benefits in terms of reduced fuel consumption. The effectiveness and reliability of these applications highly depends on the quality of the V2V communication link, which rely upon the properties of the propagation channel
