Forerunners in bi-gyrotropic materials

Forerunners (precursors) in linear, temporally dispersive, bigyrotropic materials are investigated with time-domain techniques. Bigyrotropic materials are characterized by 12 constitutive parameters (integral kernels). Specifically, the four susceptibility dyadics are all gyrotropic with a common gyrotropic axis. Pulse propagation along this axis is analyzed with dispersive (noncoupling) wave spli

The Taimyr fold belt, Arctic Siberia: timing of prefold remagnetisation and regional tectonics

Late Precambrian and Palaeozoic platform sediments from the Central-South Taimyr Peninsula (Arctic Siberia) are all remagnetised. The remagnetisation is prefold and is related to thermal remagnetisation caused by Taimyr Trap magmatism. The remagnetisation age is estimated to 220-230 Ma and, hence, is considerably younger than the ca. 251 Ma age for the main body of Siberian Trap flood basalts. The

Systerskap som politisk handling : Kvinnors organisering i Sverige 1968 till 1982

Popular Abstract in Swedish Den andra vågens kvinnorörelse uppstod i Sverige med Grupp 8 1968 under en växande antikrigsrörelse mot USA:s krig i Vietnam. En ny generation kvinnor gick ut på gatorna och krävde fri abort, gratis daghem, organiserade kampanjer mot kvinnors låga löner och sexuell exploatering. Med denna avhandling försöker jag för det första visa vad som karakteriserar den nya kvinnorThe second-wave women's movement emerged in Sweden with Group 8 in 1968, at the height of the anti-war struggle against the US war in Vietnam. A new generation of women took to the streets to demand free abortion, and free childcare, and to campaign against women's low pay and sexual exploitation. This thesis focuses on a number of women's groups? collective action and organising during a politica

Medication errors when transferring elderly patients between primary health care and hospital care

Objective: The aims were to evaluate the frequency and nature of errors in medication when patients are transferred between primary and secondary care. Method: Elderly primary health care patients (> 65 years) living in nursing homes or in their own homes with care provided by the community nursing system, had been admitted to one of two hospitals in southern Sweden, one university hospital and on

A case study of a principally new way of materials kitting - an evaluation of time consumption and physical workload

This article presents a materials kitting case study, using an alternative method for materials killing: the traditional picker-to-material principle was replaced with a material-to-picker approach. The Study was made in a materials supply workshop of an automobile plant shortly after this kitting process had been introduced. The materials kitting was video recorded and the material pickers' physi

Structural and magnetic properties of Fe/ZnSe(001) interfaces

We have performed first-principles electronic structure calculations to investigate the structural and magnetic properties of Fe/ZnSe(001) interfaces. Calculations involving full geometry optimizations have been carried out for a broad range of thickness of Fe layers(0.5-10 ML) on top of a ZnSe(001) substrate. Both Zn- and Se-terminated interfaces have been explored. Total energy calculations show

Control of excitonic and electron-hole processes in wide-gap crystals by means of elastic uniaxial stress

The time-resolved emission spectra and the excitation spectra of the main emissions have been measured for the first time in stressed and unstressed RbI crystals using synchrotron radiation of 10-30 eV at 8 K. It has been shown that the applied elastic uniaxial stress (EUS) offers promise for the separation of the elementary multiplication mechanisms of electronic excitations. A different influenc

Determination of fat content and fatty acid composition in meat and meat products after supercritical fluid extraction

Two different relatively simple, commercially available supercritical fluid extractors (SFE), Leco and Foss-Tecator, were tested for the determination of total fat content in meat and meat products. The fatty acid composition in meat and meat products was also determined after the Foss-Tecator extraction in an aliquot of the extract. Total fat was determined by weighing after the different extract

Process Development of Bioethanol Production from Wheat and Barley Residues Steam Pretreatment and SSF

Bioethanol has received increasing attention as an alternative to petrol due to the current dependency on supplies from other countries and due to the increased concentration of the greenhouse gas carbon dioxide in the atmosphere. In this thesis, the development of 2nd generation production processes for bioethanol production from the lignocellulosic part of biomass is discussed. The conversion of

SiGe Esaki tunnel diodes fabricated by UHV-CVD growth and proximity rapid thermal diffusion

A process for realisation of SiGe Esaki diodes in layers grown by ultra-high vacuum chemical vapour deposition has been developed and the first Esaki diodes are reported for this growth method. Intrinsic SiGe-layers are grown on highly boron-doped p(+)-Si layers, while post-growth proximity rapid thermal diffusion of phosphorous into the SiGe is employed to form an n(+)-layer. Tunnel diodes with a
