Rapporten beskriver förekomst och orsaker av nyodling i Sverige under 2000-talet utifrån ett antal gårdsfall där enskilda skiften nyodlats och två års statistik över skogsavverkning med ändamålet att föra över skogsmark till jordbruksmark. Statistiken diskuteras på nationell, läns- och kommunnivåer och jämförelser görs av nyodlingsarealen med befintliga arealer jordbruks- och skogsmark liksom av a

Recently, new cycles for power generation, such as wet cycles and cycles for CO2 capture, have gained increasing interest. These new cycles use some sort of dilution in the air/fuel mixture, e.g. steam or CO2. Gas turbine cycles using LCV gases can also be said to fit this description. Almost all modern gas turbines use a lean premixed combustion system, since it combines low NOX emissions with hi

For centuries rammed earth has been a method of construction in various parts of the world. It is an economical building technique as earth is an abundant cheap resource. It is durable, safe and a desirable building technique for hot climates. This paper is discussing a workshop activity in building with sustainable rammed earth construction methods in Egypt. It adds to previous research in vernac

The following article is an interpretation of a narrative in Theodoret of Cyrrhus’ collective biography about the history of the monks of Syria, the Philotheos historia. The most well-known saint of Theodoret’s own diocese was James of Cyrrhestica. His biography has a central place in the PH, but has not received as much attention as that of his name- sake James of Nisibis, or Symeon the Stylite.

We study quantization noise modeling in a low-delay vector predictive transform coder for speech signals. The coder uses a Kalman filter with a backward estimated LPC model of the speech signal combined with an additive noise model of the quantization noise. Computer simulations indicate that modeling of the quantization noise can improve the quality of the decoded speech signal. This is especiall

Transient experiments are one of many techniques available to study heterogeneous catalysis and the catalysts used. The results obtained by transient experiments contain valuable information that is helpful in explaining reaction mechanism and interaction at the catalytic surface. The work that was performed covers areas that reach from the selective (ammoxidation) and complete oxidation of propan

This is a study of how use of computer artefacts could be understood from the aspect of trust. Meanings of trust are discussed and rather than to understand trust as a possible solution to problems of uncertainty and control, trust is here seen as a fundamental aspect of life, including experiences of knowledge, certainty and control. Computer artefacts are often talked about as tools. It is argu

The proteins of the serpin family are primarily but not exclusively proteinase inhibitors, which share a common, similar structure. It is known that this structure undergoes major conformational changes upon cleavage in the serpin reactive site loop, and that these changes include rearrangements within the hydrophobic core of the molecule. AAT and the free C-terminal peptide dissociated from cleav
