An experimental and numerical study on mechanical properties, such as strength, elastic modulus, creep and shrinkage, of Self-Compacting Concrete, SCC, and the corresponding properties of Normal Compacting concrete, NC, is outlined in this article. The study included eight mix proportions of sealed or air-cured specimens with water-binder ratio, w/b, varying between 0.24 and 0.80. Half of the mixe

The dosimetry of cone beam computed tomography (CBCT) is not fully elaborated yet, and some of these systems presents dose-area-product (DAP) values after an examination rather than, as in the case of traditional CT, the doselength- product (DLP).

Popular Abstract in Swedish Denna avhandling handlar om modeller för plana solfångare, transparent isolering och verkningsgradsfaktorer. En ekvation för energiutbytet från en glasad plan solfångare härleds genom att modellera verkningsgradsfaktorn, F´, som en summa av en konstant och en temperaturberoende del. Ett alternativt sätt att testa en plan solfångare, baserat på denna modell, föreslås. EThis thesis deals with models of flat plate collectors, transparent insulation and efficiency factors. An equation for the energy output from a glazed flat plate collector is derived by modelling the collector efficiency factor, F´ as the sum of a constant and a temperature dependent part. An alternative way of testing a flat plate collector, based on this model, is suggested. A complete set of a

The polymer electrolyte fuel cell (PEFC) is considered as one of the most promising devices for providing efficient, clean and noiseless conversion of chemical energy to electrical energy. This device can provide electrical and thermal energy for transport, mobile and stationary applications ranging in a wide range of power requirements. However, in spite of its promising potential and increasing

Popular Abstract in Swedish Vår forskningsgrupp har tidigare påvisat kraftiga förändringar i genuttryck för neurotrofiner, en familj av tillväxtfaktorer för nervceller, och deras receptorer i kortikala och hippokampala nervceller vid olika hjärnskador. Det är till stora delar okänt vilken funktion neurotrofiner har efter hjärnskador, men neurotrofinsvaret skulle kunna vara en skyddande mekanism ocThis study explores the role of brain-derived neurotrophic factor (BDNF) for neuronal vulnerability and neurogenesis following cerebral ischemia in the rat. Cerebral ischemia results in selective neuronal cell loss in specific brain regions. We here demonstrate the rank order of vulnerability in two regions affected by global forebrain ischemia, i.e., hippocampus and striatum, by combining specifi

Current food systems pose one of the greatest health and environmental challenges of the 21st century. Expanded utilization of seaweed for food in Western societies seems like one promising measure in the transition toward sustainable food systems. However, introducing and expanding seaweed to new markets brings certain challenges, such as limited food acceptance and availability.

Successful technological transitions require the alignment of technologies, capabilities, infrastructure, and institutions across a wide array of industries and involving many agents. In such processes, synergies and complementarities across different fields of economic activity are crucial. When such complementarities are missing, imbalances emerge, which, in the absence of innovation, may stifle

This paper reconsiders how central banks get involved in the process of determining nominal variables such as market interest rates and inflation rates. It is argued that the traditional story deriving central bank power from its monopoly of issuing base money is flawed. That story - in its various guises - is based on the quantity equation. This equation, however, is only applicable in the hypoth
