Synthesis, Structure and Bonding in Polyiodides and Binary Metal Iodide-Iodine Systems

Polyiodides and binary metal iodide-iodine compounds have been prepared and investigated by means of X-ray diffraction, EXAFS, far-IR, Raman, UV-vis and NMR spectroscopy and quantum chemical calculations. (Et3S)[AuI4].2I2 and (Me3S)[Cd2I6]1/2.3I2 were synthesised through the reaction between the room temperature melt of trialkylsulfonium polyiodides and the corresponding metal iodides. The structu

Conceptualizations of childhood, pedagogy and educational research in the postmodern : A critical interpretation

Over the last fifty years the debate between modernism and postmodernism has surfaced in the disciplines of social sciences. Epistemologically, there is a shift away from the concept of a “found” world, “out there”, objective, knowable and factual, towards a concept of “constructed” worlds, thus problematizing postulates based on the autonomous, stable, unified, essentialized, coherent and integra

Keramik i Sydsverige: en handbok för arkeologer

Keramik hör till de vanligaste fynden vid arkeologiska undersökningaroch intar av tradition en central plats i ämnet. I samband med de senaste 25 årens utgrävningar i Sydsverige, har ett mycket stort och varierat keramiskt fyndmaterial tillvaratagits från framför allt Skåne, men även från Halland, Blekinge och Småland. Många fynd har tidigare presenterats i rapportet och andra publikationer. En sa

SI vid LTH: En utvärdering av SI-verksamheten vid fem civilingenjörsprogram vid LTH hösten 2008.

Rapporten redovisar en utvärdering av SI-verksamheten (SI = Samverkansinlärning) vid fem civilingenjörsprogram vid Lunds Tekniska Högskola under hösten 2008 tillämpat på en kurs i endimensionell analys. SI-övningarna med fokus på grupporienterat arbete och diskussioner kring svårigheter i kursen har varit ett komplement till ordinarie undervisning bestående av föreläsningar och räkneövningar. SI-ö

Experimental study of a flameless gas turbine combustor

This paper presents experimental data, performed at atmospheric conditions, on a novel flameless combustor with application to gas turbine engines. Flameless combustion is characterized by distributed flame and even temperature distribution achieved at conditions of high preheat air temperature and sufficiently large amounts of recirculating low oxygen concentration exhaust gases. Extremely low em

First steps towards a computational theory of autism

A computational model with three interacting components for context sensitive re-inforcement learning, context processing and automation can autonomously learn a focus attention and a shift attention task. The performance of the model is similar to that of normal children, and when a single parameter is changed, the performance on the two tasks approaches that of autistic children.
