Simulation and experimentation of a single-phase claw-pole motor

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

Hole-burning techniques for isolation and study of individual hyperfine transitions in inhomogeneously broadened solids demonstrated in Pr3+: Y2SiO5

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

Testing an oral assessment guide during chemotherapy treatment in a Swedish care setting: a pilot study

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

Analysis and design of a 1.8-GHz CMOS LC quadrature VCO

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

Svensk konsensus om vaccination mot cervixcancer. Vaccinprogram bör införas i grundskolan med sikte på att utrota HPV16/18

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

Conodont faunas with Lenodus variabilis in the upper Arenigian to lower Llanvirnian of Sweden

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,

Septum magnet design

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

Some nostocalean cyanoprokaryotes from lentic habitats of Eastern and Southern Africa

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

Universiteten och kompetenslandskapet : Effekter av den högre utbildningens tillväxt och regionala spridning i Sverige

Popular AbstractI Sverige har utbildningspolitiken under de senaste decennierna fått en viktig roll i att främja målsättningar också inom en rad andra politikområden, bland annat det regionalpolitiska. Högskolorna skall bidra till att utjämna sociala och ekonomiska skillnader mellan olika grupper i befolkningen, stimulera innovationsförmågan i näringslivet och generera nya företag. UndersökningarnImportant goals in Swedish higher education policy, from the late 1960s all through the 1990s, have been to increase the accessibility to higher education and to increase the supply of newly educated labour in all parts of the country. These goals are based on the assumption that geographical distance matters. Geographical distance to universities is thought to act as a barrier to university entra

Recommendations for the standardization and interpretation of the electrocardiogram: part II: Electrocardiography diagnostic statement list: a scientific statement from the American Heart Association Electrocardiography and Arrhythmias Committee, Council on Clinical Cardiology; the American College of Cardiology Foundation; and the Heart Rhythm Society: endorsed by the International Society for Computerized Electrocardiology

This statement provides a concise list of diagnostic terms for ECG interpretation that can be shared by students, teachers, and readers of electrocardiography. This effort was motivated by the existence of multiple automated diagnostic code sets containing imprecise and overlapping terms. An intended outcome of this statement list is greater uniformity of ECG diagnosis and a resultant improvement

Coil-globule transition of DNA molecules induced by cationic surfactants: A dynamic light scattering study

The compaction and aggregation of DNA induced by cationic surfactants was studied by dynamic light scattering (DLS). Furthermore, the effect on surfactant-compacted DNA of the addition of nonionic amphiphiles and salt was studied. When using sufficiently low amounts of DNA and cetyltrimethylammonium bromide (CTAB), compacted DNA molecules could be monitored by the appearance of a band characterize

Dryer Section Control in Paper Machines During Web Breaks

Web breaks in the dryer section of a paper machine cause loss of production and quality problems. After a web break, the steam pressure in the cylinders must be reduced to avoid overheating. The goal of this project is to determine optimal steam pressure trajectories during web breaks, so that the production is restarted with the same drying properties of the cylinder as before the break. A detail

Fibroblast growth factor (FGF)-2 and FGF receptor 3 are required for the development of the substantia nigra, and FGF-2 plays a crucial role for the rescue of dopaminergic neurons after 6-hydroxydopamine lesion

Basic fibroblast growth factor (FGF-2) is involved in the development and maintenance of the nervous system. Exogenous administration of FGF-2 increased dopaminergic (DA) graft survival in different animal models of Parkinson's disease. To study the physiological function of the endogenous FGF-2 system, we analyzed the nigrostriatal system of mice lacking FGF-2, mice overexpressing FGF-2, and FGF-
