The replacement of fossil fuels by renewable fuels such as biogas and biohydrogen will require efficient and economically competitive process technologies together with new kinds of biomass. A two-stage system for biogas production has several advantages over the widely used one-stage continuous stirred tank reactor (CSTR). However, it has not yet been widely implemented on a large scale. Biohydro

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

The phenomenon of “status consumption” has become increasingly evident in modern society. Although conspicuous c

Mörk materia har funnits sedan tidernas begynnelse, från den Stora Smällen. Under Universums första hundratals miljoner år var tyngdkraften från den mörka materian så kraftfull att den drog till sig den vanliga materian, som muskler till revben, och formade gigantiska strukturer. De första galaxerna växte där dessa strängar möttes.Galaxer kolliderade med andra galaxer, och slogs samman för att bil

Martin Johansson är forskargruppsledare för den här forskargruppenWe mainly study two important aspects of human kidney disease. First, we study the cellular background for kidney regeneration. The traditional concept that the human kidney lacks a stem cell compartment has recently been challenged by an alternative view, stating that stem cells indeed are localized to the kidney. The issue is thus far from settled and we are currently researching this important

The years 1988-1998 were named by World Council of Churches as The Ecumenical Decade - Churches in Solidarity with Women. On a worldwide scale, the Decade challenged member churches to portray Solidarity with Women in their contexts. Churches around the world launched a variety of projects and programs for this purpose. The Decade envisaged a new fellowship of women and men in church and society,
