Ever since the release of the Kyoto protocol the demand for CO2-free processes have been increasing. In this paper three different concepts with no or a very small release of CO2 to the atmosphere are evaluated and compared concerning plant efficiency and investment cost. A novel approach to biomass gasification is proposed to provide fuel for a combined gas turbine cycle, where the biomass is con

Popular Abstract in Swedish Avhandlingen består av två delar, den första som behandlar konstruktionen av järn-pulver maskiner, och den andra med analys av ljud från el-maskiner. I Del I, en elektrisk magnetiserad klo-pol synkron maskin på 1.6 kW har byggts. Maskinen är byggt från mjuk magnetisk material (SMC), också kallad järn-pulver. Detta materialet har isotropiska magnetiska egenskaper, som gThis thesis consists of two parts, the first dealing with the design of iron-powder synchronous machines, and the second with the analysis and prediction of the acoustic noise in electrical machines. In Part I, a 1.6 kW electrically magnetized claw-pole machine with magnetically conducting end-plates has been analyzed and a prototype tested. The machine is built from soft magnetic composite mater

Two conservation laws for mutual information in terms of directed informations between two synchronized sequences of random variables are derived, the first for the case of no conditioning and the second for the case of causal conditioning on a third synchronized sequence. As a byproduct of the derivation of the first conservation law, the directed information specifying the feedback flowing from

The book contains the first part of an investigation aimed at finding out why it is morally wrong (at least prima facie) to cause species to go extinct. That it is morally wrong seems to be a very basic and widely held intuition. It seems reasonable that a moral theory worth taking seriously ought to be able to account for that intuition. The most common attempt to answer our question is to refer

Popular Abstract in Swedish Lillhjärnans kontroll av klassisk betingning Klassisk betingning är en enkel och fundamental form av inlärning. Ett neutralt betingat stimulus (eng. conditioned stimulus eller CS), som t.e.x en ton, presenteras tillsammans med ett obetingat stimulus (unconditioned stimulus eller US), som alltid utlöser en specifik respons (eng. unconditioned response eller UR). Det kanIt has previously been shown that the cerebellum is critical for classical conditioning. The experiments presented in this thesis aimed to study how the cerebellum controls conditioned eyeblink responses (CRs) and specifically the efferent path from the cerebellar cortex to the muscles. Ferrets, decerebrated rostral to the superior colliculus and the red nucleus, were trained in a classical condit

Zeaxanthin, a carotenoid in the xanthophyll cycle, has been suggested to play a role in the protection against photodestruction. We have studied the importance of the parameters involved in zeaxanthin formation by comparing spinach plants grown in low light (100 to 250 mol m-2 s-1) to plants transferred to high light (950 mol m-2 s-1). Different parameters were followed for a total of 11 days. Our
