Theory, boundaries and political communication - The uses of disparity
While the themes of fragmentation and insufficient coherence dominated discussions in the field of media and communication studies a decade ago, today they seem less urgent, even if at times still problematic. In terms of theory, the field is well served by its permeable boundaries, since much of its theory is 'imported'. Moreover, theory needs nondoctrinaire critical stances to address the distre

The GSSP of the second (Upper) stage of the Lower Ordovician series: Diabasbrottet at Hunneberg, province of Vastergotland, southwestern Sweden
Diabasbrottet, selected by the International Subcommisson on Ordovician Stratigraphy and in 2002 ratified by the International Commission on Stratigraphy as the GSSP of the Second (Upper) Stage of the Lower Ordovician, is located on the Hunneberg Mountain in southwestern Sweden. The stratigraphic succession represents an outer shelf environment near the Baltic Shield margin. The shale-dominated, b
System Identification using LQG-Balanced Model Reduction,
System identification of linear multivariable dy-namic models based on discrete-time data can be performed using a algorithm combining linear regression and LQG-balanced model reduction. The approach is applicable also to unstable system dynamics and it provides balanced models for optimal linear prediction and control.
Experimental and computational evaluation of mass transfer resistance of paper dryer fabrics
The mass transfer aspects of synthetic dryer fabrics used in multi-cylinder paper dryers were investigated both experimentally and computationally. Experiments were performed in a convective dryer to determine which characteristics of the fabric are instrumental in controlling the drying rate. Results obtained from twelve different fabrics showed that neither the permeability nor the porosity of t
Gestational age-dependent reference values for pH in umbilical cord arterial blood at term
OBJECTIVE: Despite a change of fetal physiologic and biochemical functions with gestational age, stationary umbilical cord acid-base reference values are used as measures of obstetric care quality. The aim of this study was to assess the risk of low Apgar score relative to low pH when using stationary versus gestational age-adjusted reference values. METHODS: Umbilical artery pH was determined in

Cytokine induced airway hyperreactivity characterized in an in-vitro model of asthma
Popular Abstract in Swedish Astma är en sjukdom som karakteriseras av upprepade anfall av andningssvårigheter, orsakade av kramp, slemhinnesvullnad och segt sekret i luftvägarna. Den finns beskriven i texter redan från det antika Grekland och rapporteras idag vara en sjukdom med utbredning över hela vårt klot. Astma är den vanligaste kroniska sjukdomen bland barn och är oavsett ålder den vanligastAsthma is a chronic disorder of the lower airways, characterized by inflammation and hyperreactivity. Pro-inflammatory cytokines like tumour necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) are known to play important roles in the pathogenesis, but our knowledge how these cytokines contribute to the development of airway hyperreactivity is limited. The aims of the present study

Top-down and bottom-up processes in grassland and forested streams
The influence of predatory fish on the structure of stream food webs may be altered by the presence of forest canopy cover, and consequent differences in allochthonous inputs and primary production. Eight sites containing introduced brown trout (Salmo trutta) and eight sites that did not were sampled in the Cass region, South Island, New Zealand. For each predator category, half the sites were loc
A structural insight into the inhibition of human and Leishmania donovani ornithine decarboxylases by 3-aminooxy-1-aminopropane
The critical role of polyamines in key processes such as cell growth, differentiation and macromolecular synthesis makes the enzymes involved in their synthesis potential targets in the treatment of certain types of cancer and parasitic diseases. Here we present a study on the inhibition of human and Leishmania donovani ODC (ornithine decarboxylase), the first committed enzyme in the polyamine bio

Study on the relationship between some room acoustical descriptors
The results of a preliminary investigation into the theoretical evaluation and study of the relationship between some room acoustical descriptors used for the subjective assessment of performance halls are considered. The concern is about three parameters, namely, the inter-aural cross-correlation coefficient (IACC), the early lateral energy fraction (ELEF) or a related measure, the spaciousness S
The congenital disorders of glycosylation: a multifaceted group of syndromes.
The congenital disorders of glycosylation (CDG) are a rapidly expanding group of metabolic syndromes with a wide symptomatology and severity. They all stem from deficient N-glycosylation of proteins. To date the group contains 18 different subtypes: 12 of Type I (disrupted synthesis of the lipid-linked oligosaccharide precursor) and 6 of Type II (malfunctioning trimming/processing of the protein-b

Combustion products generated by hetero-organic fuels on four different fire test scales
The scaling of results from combustion experiments with four organic substances containing heteroatoms, carried out on four different scales, is discussed. The scales ranged from the micro-scale, using about 2 x 10(-3) kg of the substances, to large scale using about 50 kg of the substances. The content of O-2, CO, CO2, NOx, HCl, HCN and SO2 in the combustion gases were determined with special att

Interdisciplinary and prospective studies necessary to increase insight into developmental language disorders
The study of developmental language disorders is discussed from an interdisciplinary perspective. It is argued that retrospective studies have provided valuable information on developmental language disorders that needs to be integrated into a theoretical model capable of capturing the basic mechanisms of language development. Conclusion: It is concluded that interdisciplinary and prospective stud
Airway allergy to trimellitic anhydride in guinea pigs: different time courses of IgG1 titer and airway responses to allergen challenge
BACKGROUND: Trimellitic anhydride (TMA) is a low molecular weight chemical that may cause occupational asthma in human beings. The objectives of this study were to determine the time course of immune and airway responses to TMA in guinea pigs and to relate the immunologic response to the immediate responses in lung resistance (RL) and plasma exudation induced by allergen challenge. METHODS: We stu
