Dynamic Solid Oxide Fuel Cell Modelling for Non-steady State Simulation of System Applications

Most of the world's energy generation is based on fossil fuels such as coal and oil, which already today but even more in the future, will cause various problems. One issue is their limited availability, which stands in conflict to the increasing global energy consumption. Another problem is the carbon dioxide generation caused by burning fossil fuels for energy production, and is thought to be on

The prognosis for type 2 diabetic patients with heart disease. A 10-year observation study of 385 patients

The objective was to study the development and progression of heart disease in type 2 diabetic patients and to evaluate the influence of revascularisation procedures on its outcome. A 10-year observation study in 385 patients attending a hospital-based outpatient clinic was performed. A total of 156/385 patients developed myocardial infarction (n=68), angina (n=44), heart failure (n=34) or died (n

Transparent and conductive Sb-doped tin oxide SPM tips prepared by sol-gel method

The rapid progress in scanning probe microscopy (SPM) techniques in the last decade has induced an increasing need for manufacturing advanced SPM tips. One important case is conductive and transparent tips. For such tips, only a few techniques have been proposed. which are either expensive or have poor reproducibility. We here propose a simple and cheap sol-gel technique to prepare fibers with a s

The Pleasure of Management Ideas: The Discursive Formation on Kaizen

The administration and management of organizations and companies is based upon the belief in the rationality of certain ideas Ð here referred to as management ideas Ð that is, the belief in these ideas1 ability to solve problems and provide opportunities for betterment. The talk of and writings on management ideas (lexis) constitute discursive formations that precede and shapes practices (praxis),

Svart eller vit i lagens ögon

Likhet inför lagen, som utgör de etniska minoriteternas mest grundläggande skydd mot maktövergrepp och etnisk diskriminering, ifrågasattes i Rodney Kings rättegång i Simi Valley 1992. Detta utlöste en rad kravaller som lämnade spår efter sig av blod och förstörelse. Kravallernas vådsamma karaktär var en reaktion på vad de svarta betraktade som det vita etablissemangets rättsövergrepp mot dem.

Homogeneous surface-enhanced Raman scattering observed from self-assembled gold nanoparticle films deposited from the liquid-liquid interface

The self-assembled gold nanoparticle film deposited from the liquid-liquid interface has been fabricated, and homogeneous surfaceenhanced Raman scattering (SERS) of R6G molecules on the film has been observed. The SERS enhancement factor of the film is estimated to be in the range 10(8)-10(10). Occasionally, there are some sudden jumps in the Raman signal, where the signal is increased a few times

The final period of life in elderly people in Sweden: factors associated with QOL.

Whether elderly people in the final period of life have a high quality of life (QOL) and what factors relate QOL in this context, is not well known. The aim of this study was to examine the final period in life in elderly people (75 years or older) in need of help with instrumental activities of daily living (ADL), with the focus on quality of life, sense of coherence (SOC), health complaints and

Prospects for biocontrol of invasive Rosa rugosa

The biota of herbivorous arthropods and pathogenic microorganisms associated with Rosa rugosa in its native and exotic ranges is reviewed. This is done as an initial step towards the identification of potential agents for biological control of this plant species invasive in Europe and North America. It is shown that more insect (but apparently not fungal) species attack R. rugosa in its native ran

Belief & Desire : The Standard Model of Intentional Action — Critique and Defence

The scheme of concepts we employ in daily life to explain intentional behaviour form a belief-desire model (BD model), in which motivating states are sorted into two suitably broad categories. The BD model embeds a philosophy of action, i.e. a set of assumptions about the ontology of motivation with subsequent restrictions on psychologising and norms of practical reason. A comprehensive critique o

The ballad dance of the faeroese: Island biocultural geography in an age of globalisation

Boundary issues are central to globalisation - the expansion and time-space integration of human societies - and to both biological and cultural diversity. The latter are, in turn, intrinsically related in processes of coevolution that generate change in the patchwork quilt of cultural and natural landscapes. These processes are especially discernible in small island societies. This paper argues t

The Complex Genetics of Mouse Reproduction and Arhritis.

ABSTRACT Optimal breeding of mice is very important in biomedical science today. The understanding why some strains breed better and some worse enable scientists to create better in vivo models for human diseases. The aim of this thesis was to identify and characterize new genetic regions linked to reproductive performance and autoimmune inflammation in female mice. Collagen-induced arthritis (CIA

N-terminal peptides from unprocessed prion proteins enter cells by macropinocytosis

A peptide derived from the N-terminus of the unprocessed bovine prion protein (bPrPp), incorporating the hydrophobic signal sequence (residues 1-24) and a basic domain (KKRPKP, residues 25-30), internalizes into mammalian cells, even when coupled to a sizeable cargo, and therefore functions as a cell-penetrating peptide (CPP). Confocal microscopy and co-localization studies indicate that the inter

Effects of sample pretreatment and sequential fractionation by centrifuge drainage on concentrations of minerals in a calcareous soil solution

Soil solution is the direct source of mineral nutrients to vascular plants. Soil solutions of sieved samples at water-holding capacity of a seminatural calcareous soil, never cultivated or treated by fertilizers, were collected by sequential centrifugation at 24-18,900 X g relative centrifugal force (RCF), followed by ultrafiltration (0.2 mu m), and analysed for Al, Ca, Fe, K, Mg, Mn, Mo, Na, P, S
