Sensory ecology of feeding in the hummingbird hawkmoth Macroglossum stellatarum (Lepidoptera : Sphingidae)
The European hummingbird hawkmoth, Macroglossum stellatarum (Linnaeus 1758), drinks nectar while hovering in front of flowers of all colours, odours, sizes and shapes. Naive moths orient predominantly towards visual stimuli and prefer blue flowers with a radial pattern and a central contrasting spot. Hummingbird hawkmoths have trichromatic colour vision and can learn any colour and different patte
Smoking in pregnancy in relation to gender and adult mortality risk in offspring: the Helsingborg Birth Cohort Study.
Background: Smoking in pregnancy is a well-documented risk factor for fetal growth impairment and poor perinatal outcomes. Less is known about the long-term effects of maternal smoking on offspring mortality. Methods: A follow-up study in national registers on total mortality and cancer based on a birth cohort from Helsingborg, Sweden, including data on 2,010 sons and 1,982 daughters born to mothe
No difference in body weight decrease between a low-glycemic-index and a high-glycemic-index diet but reduced LDL cholesterol after 10-wk ad libitum intake of the low-glycemic-index diet
Background: The role of glycemic index (GI) in appetite and body-weight regulation is still not clear. Objective: The objective of the study was to investigate the long-term effects of a low-fat, high-carbohydrate diet with either low glycemic index (LGI) or high glycemic index (HGI) on ad libitum energy intake, body weight, and composition, as well as on risk factors for type 2 diabetes and isc

Further insight in the web consolidation process - Part II. Triangular phase diagrams for analysis of paper shrinkage
A new type of triangular phase diagram has been developed in which both the volume fractions and the shrinkage modes can be visualised and compared for the consolidation process in the paper dryer. The triangular phase diagrams show the development of the solid, the liquid and the gas volume fractions as well as the shrinkage relative to either ideal or no shrinkage of the sheets. Analysis showed
Painting and firing of late Etruscan votive terracottas
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

Linear and non-linear spectroscopy of Ho3+-doped YVO4 and LuVO4
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
The lower and middle Cambrian of Sweden: trilobites, biostratigraphy and intercontinental correlation
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
Close Approximations of Minimum Rectangular Coverings
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

Simulation of Combustion and Fire-Induced Flows in Enclosures
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

Wave Splitting in Direct and Inverse Scattering Problems
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
