Änkekejsarinnan Cixi styrde Kina under kejsardömets sista halvsekel. Hon utmålades länge som maktgalen och grym, men på senare tid har en mer nyanserad bild presenterats. I den här uppsatsen analyseras hur ett antal händelser i Cixis liv i relation till Guangxu-kejsaren och hans konkubin Zhenfei har beskrivits i olika källor. Syftet är att se vad dessa händelser säger om Cixi som person och om detEmpress Dowager Cixi governed China during the final five decades of the Qing dynasty. She was for many years depicted as a cruel megalomaniac, lately Cixi has been described in a more nuanced way. This paper seeks to analyze how a selection of sources describe a number of specific events in connection with Cixi and the Guangxu-emperor and his concubine Zhenfei. The objective is to discuss what th

En kvalitativ fallstudie där vi med hjälp av öppna personliga intervjuer talat med folk i ledande befattningar på vår fallkoncern Elektrokoppargruppen för att forma oss en bild av hur budgeten fungerar på företaget. Utifrån valda teorier om budget och dess process har vi sedan analyserat företaget och dess situation. Utav budgetprocessens tre delar har vi kommit fram till att budget är ett effekti

Laminar burning velocities, S-L, of ethane + air and propane + air flames within an equivalence ratio range between 0.8 and 1.3 were determined at atmospheric and elevated pressures up to 4 atm. Measurements were performed in non-stretched flames, stabilized on a perforated plate burner at adiabatic conditions, created using the heat flux method. Initial unburnt gas temperature was 298 K. These ne

This article describes the systematic design of a control structure for a biological wastewater treatment process as given by the test-bed Benchmark Simulation Model No. 1 (BSM1) and Activated Sludge Model No. 1 (ASM1). The objective of this work was to formalize and implement a systematic and yet simple procedure for the selection of control structures in wastewater treatment plants (WWTPs) and t

The analysis of annual extremes of hydrological and meteorological variables is frequently complicated by the presence of gaps in record, and when records are not only fragmented but also short, it is necessary to utilize to the full the information contained in them. One method is to abstract for statistical analysis all extreme events whose peaks exceed a pre-selected threshold value, but the th

Bone mineral density (BMD) measurements are widely used to estimate the risk of osteoporotic fractures. In addition, many other risk factors have been identified, sonic of which are known to add to the risk independently of BMD measurements. The combination of BMD with such risk factors increases the gradient of risk/standard deviation (SD) than that achieved by BMD alone. In this paper, we report

In this paper we analyze the performance of three low-complexity channel estimators, based on the discrete Fourier transform (DFT), for orthogonal frequency-division multiplexing (OFDM) systems. Estimators of this type have been analyzed for discrete-time channels, and we extend this analysis to continuous-time channels. We present analytical expressions for their mean-squared error (MSE) and eval

Laminar burning velocities of acetone + air mixtures at initial gas mixture temperatures of 298, 318, 338 and 358 K are reported. Non-stretched flames were stabilized on a perforated plate burner at 1 atm, and laminar burning velocities were determined using the heat flux method, at conditions where the net heat loss from the flame to the burner is zero. The overall accuracy of the burning velocit

Imaging and inverse scattering of seismic reflection data can be formulated in terms of a certain class of Fourier integral operators. We present an approximation and discretization of such operators following a multiscale approach, based on wave packets as the quanta for representing seismic data. One of the key ingredients in our approach is the coupling of dyadic parabolic decomposition and pro

This text deals with a problem concerning processes of the productive power of knowledge. We draw on so called poststructural theories challenging the classical image of thought – as hinged upon a representational logic identifying entities in a rigid sense – when formulating a problem concerning the gap between knowledge and the object of knowledge. More specifically we are looking at this proble

ABSTRACT Radioimmunotherapy (RIT) consists of using monoclonal antibodies (mAbs) recognizing tumor-selective antigens, as carriers of cytotoxic radionuclides to tumor tissue. RIT has been effective in lymphoma but less successful in solid tumors. mAbs slowly diffuse from the vasculature into and through solid tumors, resulting in slow, limited accretion of antibodies. The outcome is a low tumor-to

Kultursemiotiken per se analyserar mötet mellan kulturer. Begrepp som ego-kultur, extrakultur och icke-kultur är centrala i undersökningar som syftar till att blottlägga den självbild en kultur gör av sig själv i mötet med en annan. Dessa begrepp har paralleller på individnivå med de personliga pronomina i språket. I den uppsats jag ämnar presentera kommer jag därför att koncentrera mig på en disk

The universally recognised action spectrum for the UV-induced conversion of 7-dehydrocholesterol to previtamin D3 in human skin was published in 1982, and indicates a maximum at about 297 nm with essentially no production above 315 nm. This work represents a milestone in research on vitamin D, but limitations in the original data should be recognised. Various findings have arisen in recent years w

Purpose: This study evaluated postoperative complications of percutaneous nephrolithotomy (PCNL) and the influence of selected factors on the risk of complications using the Clinical Research Office of the Endourological Society (CROES) PCNL Global Study database. Patients and Methods: The CROES PCNL Global Study collected prospective data for consecutive patients who were treated with PCNL at cen
