We show that the relation of second order stochastic dominance, which has found widespread use in models of economic behavior under uncertainty, may be described in terms of conditional expectation. If a distribution G second order stochastically dominates another distribution F, then there are random variables g and f with distributions G and F, respectively, such that g can be obtained from f by

Free radicals have been suggested to play a role in the development of diabetic retinopathy. The aim of the present study was to examine whether the metabolic perturbations caused by high-fat feeding of two strains of mice, the C57BL6/J mice and the NMRI mice, interfere with one of the free radical enzyme defense systems in the retina, i. e., glutathione (GSH), and whether morphological changes oc

Over a decade ago, the concept of objectively evaluating the performance of control strategies by simulating them using a standard model implementation was introduced for activated sludge wastewater treatment plants. The resulting Benchmark Simulation Model No 1 (BSM1) has been the basis for a significant new development that is reported on here: Rather than only evaluating control strategies at t

The difference between the Western and the “Indian” view of nature has sometimes in the literature on environmental ethics been expressed as the difference between an anthropocentric and biocentric worldview. This argument often juxtaposes two models, without consideration of context. My aim in this article is to investigate those aspects of Amerindian cosmologies that have led Western scholars to

Purpose - The purpose of the paper is to evaluate theoretically and experimentally the static and dynamic characteristics of a single-phase claw-pole motor using soft magnetic composite (SMC) for the stator core. Design/methodology/approach - On the basis of the static characteristics, which are measured and obtained from a series of 3D FE magnetostatic solutions, the dynamic characteristics are s

Due to their narrow homogeneous linewidths, rare-earth ions in inorganic crystals at low temperatures have recently been given considerable attention as test materials for experiments in coherent quantum optics. Because these narrow linewidth transitions have been buried in a wide inhomogeneous line, the scope of experiments that could be carried out in these materials has been limited. However, h

Oral complications are common in patients with haematological malignancies who undergo chemotherapy treatment. A pilot study including 16 haematological patients was carried out to evaluate the oral status using an Oral Assessment Guide (OAG) and to test the reliability of the OAG. The oral assessments were made daily by registered nurses at a Department of Internal Medicine in Sweden. Once a week

This paper presents a quadrature voltage-controlled oscillator (QVCO) based on the coupling of two LC-tank VCOs. A simplified theoretical analysis for the oscillation frequency and phase noise displayed by the QVCO in the 1/f/sup 3/ region is developed, and good agreement is found between theory and simulation results. A prototype for the QVCO was implemented in a 0.35-/spl mu/m CMOS process with

Vaccination against the Human Papillomavirus (HPV) has recently been approved as a means to prevent cervical cancer. The Swedish Institute for Infectious Disease Control and the Swedish Society for Obstetrics & Gynecology arranged a consensus conference to discuss design of future cervical cancer prevention programs. Conclusions include that preventive programs should aim at eradication of onc

Lenodus variabilis occurs in an interval in the lower to middle Kundan Stage which includes the Arenig-Llanvirn boundary. The lower part of its range constitutes the L. variabilis Zone, the upper part, where it co-occurs with Yangtze-placognathus crassus, making up the Y. crassus Zone. The conodont faunas of these two consecutive conodont biozones have been investigated in 14 sections from south,

New magnetic DC septa are designed for the upgraded Max I and the new Max III storage rings, respectively. The new septum is made magnetically symmetric with a magnetic flux filter in the septum nose, The residual stray fields in the ring tube become almost linear and the usually strong stray fields close to the septum sheet are eliminated. If necessary a final correction of the linear part could

The article comprises the second part (Nostocales) of our study of little known planktic and metaphytic cyanoprokaryotes (cyanophytes, cyanobacteria) from ponds, lakes and water reservoirs in East and Southern Africa. The morphology and variation of 17 species was studied, and comments about their ecology and taxonomy are included. Seven new species are defined: Anabaena austro-africana, A. carmic
