Ancient Italic terracottas were painted before or after firing depending on their function, as suggested by previous analyses. However, concerning the votive terracottas, there seems to have been no anlayses carried out, suggesting either a fired or non fired paint. Methods and problems associated with an ongoing research on some votive terracottas from Tessennano in Southern Etruria are considere

Rare-earth-doped crystals can be attractive materials for quantum information processing, because of the long coherence times that can be expected, in particular, from non-Kramers ions. In this paper, Ho3+-doped yttrium and lutetium vanadate single crystals have been investigated using linear and coherent optical spectroscopy. For Ho3+:YVO4, the crystal-field levels of the I-5(8), F-5, F-5(4) and

Popular Abstract in Swedish Kambrium är ett tidsavsnitt av jordens historia som spänner från ca 542 till 488 miljoner år sedan. Under denna tid utvecklades livet, främst djur, i en rasande takt genom något som brukar kallas den kambriska explosionen, en ekologisk förändring utan dess like. Bland de nya livsformer som fick de kambriska haven att koka av liv märks skalbärande djur som små armfotingaThis thesis is based on studies of Cambrian successions in Sweden, with particular focus on the middle Cambrian biostratigraphy and its correlative relationship to the proposed global agnostoid zonation. The investigated material, mainly trilobites, was collected from both outcrops and drill cores from five provinces in Sweden: Skåne (Scania), Öland, Västergötland, Jämtland and Lapland. The Almba

We consider the problem of covering arbitrary polygons with rectangles. The rectangles must lie entirely within the polygon. (This requires that the interior angles of the polygon are all greater than or equal to 90 degrees.) We want to cover the polygon with as few rectangles as possible. This problem has an application in fabricating masks for integrated circuits. In this paper we will describe

Numerical modeling of combustion in flames and gas flows and gas flows generated by fires in compartments has been carried out. The laminar flamelet model has been used to model combustion in different degrees of vitiation in order to model fire gas recirculation which occurs in compartment fires. CFD modeling (computational fluid dynamics) has been used in the calculation of the flow field. The f

The focus of this thesis is on the use of wave splitting in electromagnetic direct and inverse scattering problems. Wave splitting offers a decomposition of wave fields into appropriate input and output wave constituents. Several different wave splittings are studied including one-dimensional, multi-dimensional energy-flux, and multi-dimensional locally exact wave splittings. The Bremmer series is

Cystatin C (CstC) is a potent cysteine-proteinase inhibitor. The structure of the mouse CstC-encoding gene (Cst3) was examined by sequencing a 6.1-kb genomic DNA containing the entire gene, as well as 0.9 kb of 5′ flanking and 1.7 kb of its 3′ flanking region. The sequence revealed that the overall organization of the gene is very similar to those of the genes encoding human CstC and other type-2

The problems following the translation of “queer theory” and of the term ”queer” into a non-American context still have an impact on the debates in the field of queer studies. Through a presentation of the discussions held at the PhD-course What’s up in Queer Theory? Recent Developments in Queer Studies organized in May 2007, the article investigates some of the implications following the translat

This paper describes a flexible and modular 9-degrees-of-freedomnonlinear dynamic handling model for a tractor-semitrailer combinationvehicle. The equations of motion are derived from the fundamentalequations of dynamics in Euler's formulation. The primary aim of themodel is simulations of handling scenarios with active yaw control,using unilateral braking and possibly tractor rear wheel steering.
