This thesis addresses the corporate sustainability process and different tools to assist the process of generating corporate strategies towards sustainability in the energy sector. The focus of the research was in backcasting approaches. The main outcome of the work is a framework for corporate sustainability for the energy sector. The framework is constructed around a three step strategic plannin
Aiming to start a constructive debate,“A tour to sustainability?” examines the preparedness of the tour operating sector to undertake the challenges of sustainable tourism. Drivers and barriers for acknowledging operators’ share of impacts and consequently their responsibilities for actions are presented and analysed further. The influential potential of tour operators in tourism industry is defin
This paper presents a custom chip for linearization of RF power amplifiers using digital predistortion. The chip has been implemented in a standard digital 0.8 mu m CMOS process with standard static cells and single-phase clocking. A systolic complex multiplier based on distributed arithmetic constitutes the core of the chip. The nonlinear function is realized with a look-up table containing compl
Protein kinase B is known to mediate a number of biological responses to insulin and growth factors, its role in glucose uptake being one of the most extensively studied. In this paper, we have employed a recently described allosteric inhibitor of PKB, Akti, to clarify the role of PKB in lipid metabolism in adipocytes - a subject that has received less attention. Pretreatment of primary rat and 3T
Elements of the Ordovician conodont genus Protopanderodus have been investigated in order to provide a model of reconstruction for its oral apparatus. In total, 4202 elements from the five named species representing this genus in the Swedish Middle Ordovician are included in this study; P. rectus, P. parvibasis, P. graeai, P. robustus, and P. calceatus. The well-preserved specimens were studied in
Popular Abstract in Swedish I Män, våld och moralarbete uppmärksammas hur män, som frivilligt sökt sig till verksamheter där det erbjuds behandling för våld i nära relationer, rapporterar om sina erfarenheter. Rapporteringarna består dels av svar på frågeformulär, dels genom deltagande i samtalsintervjuer. Författaren analyserar hur männen förklarar sina handlingar och gestaltar återberättade erfMen, violence and moral work- Reports from help-seeking men at treatment centers working with violence in close relationships Men’s violence against women is an extensive social problem. In the 1970s, a new kind of centers were established in the US and UK, focusing on treating men who had been violent against their wives or girlfriends, the aim which is to end the men’s violent behavior. In the
Neural transplantation is over a century old, but the modern era encompasses only the last 30-40 years. For most of this time period, research has focused on reversing disability engendered by neurologic disease and brain damage. Only recently was it recognized that the underlying neurological disease itself might negatively impact the grafted neurons. We have found that a subset of neurons within
A power-series expansion method for rigorous analysis of the guided modes in a cylindrical, radially inhomogeneous, dielectric waveguide is presented. The method is developed for an arbitrary piece-wise polynomial permittivity profile. The field solutions of the inhomogeneous core are constructed by a sequence of power-series expansions. Convergence is ensured and accuracy maintained by regulating
Radiative lifetimes for the levels of the 3s(2)3p(2)4p configuration in neutral phosphorus have been determined experimentally for the first time and also theoretically. Experiments were performed by using two-photon UV laser excitation and subsequent fluorescence detection in a laser-produced plasma. In relativistic Hartree-Fock calculations, the Cowan code extended to 42 configurations was used.
The aim of this study was to demonstrate safe orthotopic transplantation of porcine donor hearts harvested 24 hours after brain death and preserved for 24 hours before transplantation.
Segmental defects of long bones are notoriously difficult to treat. This study evaluates eight cases in which the Masquelet technique of induced membranes was used. The primary purpose was to assess the results compared to other types of bone reconstruction and share our tips and tricks to improve the outcome.
A prototype to a water-cooled applicator to be used in transurethral laser-induced thermotherapy of benign prostatic hyperplasia was developed. The flexible applicator was made of Teflon(TM) tubes except for the distal outer part which was made of glass, providing a transparent medium for laser radiation and enabling efficient cooling of the surrounding tissue. For heating, laser light from a Nd:Y
Background/aim: People with profound cognitive disabilities are not expected to learn powered mobility use. The Driving to Learn project focussed on what this population could achieve from practising in a joystick-operated powered wheelchair. By means of using grounded theory methodology an eight-phase process 'growing consciousness of joystick-use' was identified. In addition, a tool for assessme
Objectives. BMD in the hand, as evaluated by digital X-ray radiogrammetry (DXR), has been suggested to be a predictor for joint damage in RA. A predictor for long-term prognosis might also predict increased mortality in RA. The aim of the present study was to evaluate BMD in the hand as a predictor for all-cause mortality. Methods. In 1978, 152 consecutive patients (78% women, mean disease duratio
Two-tone frequency modulation spectroscopy (TTFMS) is applied to the determination of water activity using an 820-nm GaAlAs diode laser. By measuring the relative light absorption of water vapor over a solution and over a pure water reference, the water activity in the solution is determined. Fast, nonintrusive, and selective measurements are demonstrated. The detection limit for measuring a relat
The function of the immune system requires coordinated expression and action of many genes and proteins. With the emergence of high throughput technologies it has become possible to target human immunity from a systems biology point of view. To perform systems biology studies with comparable results we need not just a reference gene and protein set but also useful and descriptive reference categor
BACKGROUND AND PURPOSE: Previous reports concerning sex-related differences in stroke management and outcome are inconsistent and are sometimes difficult to interpret. We used data from a national stroke register to further explore possible differences between men and women in baseline characteristics, stroke treatment, and outcome. METHODS: This study included 24 633 stroke events registered in R
