The purpose of this work is to investigate the interaction between transport processes and chemical reactions, with special emphasis on modeling mass transport by the Lattice Boltzmann method (LBM) at microscale of the anode of a solid oxide fuel cell (SOFC). In order to improve the performance of an SOFC, it is important to determine the microstructural effect embedded within the physical and che

The article presents the sociology of philosophy as an empirical undertaking that relies on certain types of empirical material and modes of utilizing data. It also discusses the sociology of philosophy as a theoretical undertaking that thematizes the relation between social being and philosophical thought on the one hand, and the relation between social being and validity on the other hand.

Abstract in German Zugefuehrte Luftporen veraendern die mechanischen Eigenschaften von Beton. Sie sind erforderlich, um den Frost-Tausalzwiderstand sicherzustellen. Der Beitrag zeigt, dass Hochleistungsbeton auch ohne Luftporenbildner eine hohe Frost-Tausalzbestaendigkeit aufweisen kann, wenn die vorgestellten Massnahmen umgesetzt werden.Freeze-thaw resistance of high performance concrete. Entrained air-pores reduce all mechanical properties of concrete. On the other hand, air-filled pores are required in order to secure freeze-thaw resistance. The article shows that high performance concrete has potential of freeze-thaw resistance also without air-entrainment, or with very low air-entrainment. Corresponding measures are presented

The objectives of this study were to examine potential clinical and neuropsychological changes over time in non-demented patients with subjective memory complaints (

Objectives - To detect post-operative sequelae of sural nerve biopsy. Materials and methods-- A questionnaire mailed to type 1 diabetic patients (n = 24; male/female 23/1; reply n = 23) 2 years after biopsy. Results - Type 1 diabetic patients (age 56 [11]; median [interquartile range]) had a long duration of diabetes (DM; 20 [19] years) and all had neuropathy. Three out of 24 patients developed in

BACKGROUND: Matrilysin (MMP-7) elevation after radiotherapy is shown in humans. Matrilysin regulates certain cytokines and the production of bactericidal proteins when the mucosa is exposed to bacterial antigens. We investigate the effect of irradiation on matrilysin and microflora in murine bowel, after modulation with antibiotics. METHODS: Animals were divided into two different groups a radiati

Multiple myeloma (MM) is consistently preceded by the precursor state, monoclonal gammopathy of undetermined significance (MGUS). The average annual risk of progression from MGUS to multiple myeloma is 0.5% to 1.0%. Current guidelines suggest life-long clinical follow-up of individuals diagnosed as having MGUS depending on risk stratification. The impact of diagnosing and conducting clinical follo

Blix et al. found in a recent meta-analysis (MA) that intrapartum fetal surveillance with ECG ST analysis (STAN) results in a significant 36% decrease in metabolic acidosis at birth compared to cardiotocography (CTG) alone (1). This demonstrates that STAN monitoring could better than CTG alone protect against hypoxia proceeding to metabolic acidosis. However, by referring to the weak association b
