For biomass fuelled CHP in sizes below 100 kW, Stirling engines are the only feasible alternative today. Using wood powder as fuel, the Stirling engine can be heated directly by the flame like when using a gaseous or liquid fuel burner. However, the combustion chamber will have to be much larger due to the slow burning of the fuel. To avoid sintering of ash the flame temperature in a biomass burne

Jones (2002) identified several discourse functions of antonymy, each of which is loosely associated with a number of contrastive constructions in written English. Subsequent work (Jones, 2006; Jones and Murphy, 2005; Murphy and Jones, 2008) demonstrated that these functions are found in other modalities/registers of English, albeit with some differences in distribution. This article takes a first

A fully integrated differential class-AB power amplifier has been designed in a 0.25 um CMOS technology. It is intended for medium output power ranges such as Bluetooth class 1, and has an operating frequency of 2.45 GHz. By using two parallel output stages that can be switched on or off, a high efficiency can be achieved for both high and low output power levels. The simulated maximum output powe

Popular Abstract in Swedish I denna studie har de grundläggande aspekterna på mass- och värmetransport i membrantekniken pervaporation studerats. Speciell tonvikt har lagts vid pervaporations användbarhet i samband med aromämnesåtervinning. Masstransporten i pervaporation påverkas av ett yttre masstransport- motstånd kallat koncentrationpolarisation. Detta fenomen kan orsaka att fluxen av de seleIn this study, the fundamental mass and heat transfer properties of the membrane separation process called pervaporation were investigated. The suitability of pervaporation for aroma compound recovery was especially evaluated. The mass transfer in pervaporation is affected by an external mass transfer resistance in the liquid feed boundary layer, i.e. the concentration polarization phenomenon. Th

Popular Abstract in Swedish Anpassningen av geofysiska metoder till infrastrukturtillämpningar är en viktig del i utvecklingen av geoteknisk förundersökningsmetodik. Det som här benämns geotekniska förundersökningar hänvisar till alla undersökningar som görs före eller under konstruktion, alltså sådana som syftar till att stödja och förbättra en konceptuell geologisk modell så väl som sådana som sThe adaptation of geophysical methods for civil engineering purposes represents an important contribution to the development of geotechnical site investigation methodology. The term geotechnical site investigation here refers to all investigations performed prior to or during construction; i.e. investigations to support and refine a conceptual geological model as well as to provide a model of geot

En tredjedel av Sveriges högskolestudenter studerar idag på distans. SCB genomförde därför 2012 studien - Distansutbildning på högskolan, med syfte att kartlägga studenters avsikter, attityder, samt den upplevda kvaliteten av distansutbildningen. Resultatet visade att: Studenter är nöjda Intresset för ämnet är avgörande Flertalet avser inte att slutföra distanskursen Distansstudier är en bisyss

Translated, "Gene Technology and the Public. An Interdisciplinary Perspective (eds Susanne Lundin & Malin Ideland), Nordic Academic Press, 2000.

From its early days, the academic debate on public goods has focused on discrepancies or trade-offs regarding the provision of public goods on the one hand and private goods on the other. However, both the extension of the public domain and an increasing interdependence in international relations clearly drive the expansion of an agenda in which there are a growing number of cases where public goo

I ett oroligt och våldsdrabbat Palestina satsade Anglikanska kyrkan på fredsbyggande utbildning under den brittiska mandatstiden 1920-1948. Intentionen bakom skolorna var dialog mellan barn av olika trosuppfattningar som indirekt skulle syfta till fredsfostran. I de anglikanska skolorna blandades judiska, kristna och muslimska elever med olika nationell bakgrund. Detta var ett unikt försök att sk

This paper analyses the potential biomass supply in the 15 EU countries, 8 new member states and 2 candidate countries (ACC10), plus Belarus and the Ukraine. For this purpose five scenarios were designed to describe the short-, moderate- and long-term potential of biomass-for-energy. Our assessments show that under certain restrictions on land availability, the potential supply of biomass energy

Popular Abstract in Swedish Blodcirkulationen fungerar i kroppen som ett transport system för proteiner, syre och andra metaboliter. Blodet har den svåra uppgiften att vara flytande och samtidigt kunna koagulera på ställen där kärlet går sönder. Störning i denna balans leder till sjukdomar som hjärtinfarkt och blodpropp eller motsatsen svåra blödningar. Det protein som jag har studerat ingår vid The subject of this thesis is the activated protein C (APC)-mediated inactivation of factor Va. The activated form of factor V (FVa) is a procoagulant cofactor for Factor Xa (FXa) in the conversion of prothrombin to thrombin. The procoagulant function of FVa is down regulated by APC through proteolytic cleavage at three sites, Arg306, Arg506 and Arg679. The cleavage at Arg506 is kinetically favore
