Crystal chemistry of Fe-Ti oxides in mafic rocks and metabasites: A study aimed at refinement of geological tools and interpretations

This thesis consists of four subprojects: (A) ‘Clouding of plagioclase by Fe-Ti oxides’, (B) ‘Fe-Ti oxides during high-pressure metamorphism of mafic rocks’, (C) ‘Magnetic study of Fe-Ti oxides in mafic rocks and metabasites’, and (D) ‘Topotactic phase transitions in oxide minerals’. A) In southern Sweden dolerite dikes and gabbros with clouded plagioclase are common. The crystal structures of th

Heat losses from a novel type of district heating culvert

In this paper the heat losses from a novel type of district heating culvert, termed Elgotherm, is investigated and compared to conventional culvert. The insulation material is made of expanded polystyrene and the culvert consists Of four cross-linked polyethylene pipes. The heat losses are calculated using both a time dependent and a stationary finite element model. Measured data from an existing

Identification of Step Atoms by High Resolution Core Level Spectroscopy

Vicinal Rh(111) surfaces are studied with high resolution core level photoemission. We demonstrate the possibility to distinguish between the different kinds of surface atoms on these surfaces by virtue of their 3d core level binding energies. In particular, the low coordinated step atoms are found to exhibit a clear fingerprint in Rh 3d spectra. We demonstrate how this may be used to show that in

Media Abstraction Framework for the Pervasive Middleware PalCom

Pervasive middleware systems are important for enabling the configuration and coordination of the services provided by devices in pervasive environments. PalCom is an example of such a system that aims to enable interaction among pervasive services over heterogeneous networks. In this paper we discuss the need for providing networking-media independent messaging among pervasive devices, and identi

All-diode-laser ultra-violet absorption spectroscopy and temporal gas correlation spectroscopy

Here, we present a scheme producing UV radiation around 302 nm by sum-frequency generation in beta-barium borate employing a blue and a near-infrared diode laser. The diode-laser-based spectrometer has a mode-hop-free tuning range of 50 GHz and can be used for high-resolution spectroscopic detection of sulfur dioxide. Differential measurements of several sulfur dioxide gas concentrations, at low p

The Molecular Architecture of the Chloroplast Thylakoid Membrane. Mapping of protein complexes in different structural domains and effect of light induced protein phosphorylation on domain composition.

Non-detergent procedure for isolation of sub-thylakoid vesicle populations derived from different structural domains of the chloroplast thylakoid membrane has been developed. Sub-thylakoid vesicles representing the grana, grana core, stroma lamellae and the grana margins have been isolated and their protein composition has been investigated. Furthermore a novel non-detergent procedure for investig

To See or Not to See a Sexually Abused Child in a Picture

Popular Abstract in Swedish Sexuella övergrepp väcker starka känslor hos oss. Ibland tycks känslorna bli så svåra att vi försöker utestänga den plågsamma verkligheten genom att "blunda" för faktum. För att studera hur människor handskas med förekomsten av ett sexuellt övergrepp på ett barn i en bild, framställdes en bild, som avsåg att visa ett sådant övergrepp. Bilden visades för ett stort antal This investigation comprises five studies of factors determining adults' interpretations of a picture (Threat), drawn to represent sexual abuse of a child. The sexes of the two persons in the picture were on purpose drawn ambiguously. In Study I, the Threat picture was interpreted by 515 undergraduates in three experiments, all resulting in the same four interpretation categories, and similar freq

Bed material deposition in cyclones of wood fuel fired circulating fluidized beds (CFBs);

Bed material samples were collected at different times from a full-scale combustion boiler, and bed material deposits were taken from the cyclone and the riser at two different occasions from a wood-fired circulating fluidized bed boiler (104 MWth). The bed materials and the bed material deposits were analyzed with environmental scanning electron microscopy/energy-dispersive X-ray spectroscopy (ES
