It has been predicted theoretically that for some environments, the capacity of wireless multiple-input multiple-output systems can become very low even for uncorrelated signals; this effect has been termed "keyhole" or "pinhole". In this paper the first unique measurements of this effect are presented. The measurements were performed in a controlled indoor environment that was designed to obtain
Objective. To determine the plasma levels of the renal functional markers creatinine, urate, cystatin C, beta(2)-microglobulin and beta-trace protein in samples from the first, second, early third and late third trimesters of 398 healthy women with uncomplicated singleton pregnancies. Material and methods. Plasma samples from 58 healthy non-pregnant women served as controls. The creatinine levels
The peroxy radical forms a cyclic complex with hydrogen peroxide, with both entities acting as hydrogen bond donors and as hydrogen bond acceptors. The strength of the complex is very similar to that of the hydrogen peroxide dimer.
This study was designed to investigate suicide attempters' views on problems underlying their suicidal behavior. A questionnaire comprising 17 problems was presented to 54 non-consecutive patients (men/women=25/29, mean age 36 ±14 years) admitted to a specialized psychiatric ward following an attempt. (In the large majority of cases the method was self-poisoning. 37% had previously attempted suici
Is the decline of the increasing incidence of non-Hodgkin lymphoma (NHL) in Sweden and other countries a result of cancer preventive measures? The yearly age-standardized incidence of NHL increased significantly in Sweden during 1971-1990, for men an average of 3.2% and for women 3.1%. The corresponding figures for 1991-2000 were -0.8% and -0.2%, respectively. A decline of the increasing incidence
Purpose: To assess the value of the combined use of dynamic susceptibility contrast-enhanced perfusion magnetic resonance imaging (MRI) and conventional contrast-enhanced MRI for the follow-up of treatment of glioblastoma multiforme (GBM). Material and Methods: 79 examinations were performed in six surgically and immunogene-treated patients and two surgically treated patients. Ratios of the relati
Genom bevarade handböcker och skrifter vet vi idag mycket om tal och talutbildning i antiken. Denna kunskap kan vi idag använda som analysredskap. Jag beskriver i denna korta översikt de mest elementära dragen i antik retorik och ger exempel på hur den bidrar till tolkningen av NT. Den retoriska textanalysen hjälper så * att se argumentationsflödet i texten * att upptäcka textens funktion * att sThis article summarizes some main features which characterize New Testament scholarship with regard to rhetorical criticism/rhetorical analysis. The first part shows the background of rhetoric in Aristotle's basic observations of how communication between men is persuasive. The actualization and application of rhetorical analysis since Perelman's and Betz' work is also shortly sketched. The second

Jellyfish belong to one of the oldest extant animal phyla, the Cnidaria. The first Cnidaria appear in the fossil record 600 million years ago, preceeding the Cambrian explosion. They are an extremely successful group present in all marine environments and some freshwater environments. In contrast to many animal phyla in which vision is a primary sense Cnidarians do not, generally, employ image for
The biomass and bacterial ingestion rates of mixotrophic phytoflagellates were examined on diurnal and seasonal scales in oligotrophic Lake Skarlen (S. Sweden). Ingestion rates were measured using fluorescent microspheres in situ on three depths every 6(th) hour during 24 hours in summer in order to quantify diurnal variations and once at midday during autumn, winter and spring. Mixotrophic phytof
This paper presents an analysis of phase noise in multiphase LC oscillators, and measurement results for several CMOS quadrature-voltage-controlled-oscillators (QVCOs) working in the 2-GHz frequency range. The phase noise data for a so-called BS-QVCO (-140 dBc/Hz or less at 3 MHz frequency offset from the carrier, for a power consumption of 20.8 mW and a figure-of-merit of 184 dBc/Hz) show that ph
In 2000 the European Council agreed on the so called ‘Lisbon Strategy’, the purpose of which is to make the European Union the strongest and most competitive economy in the world and also to fight unemployment and secure social welfare systems. One year later, in 2001, an ‘environmental dimension’ was supplemented to the Lisbon Strategy at the Council meeting in Gothenburg. An ‘EU Strategy for Sus
OBJECTIVES. To compare family physicians' reported practice habits on hypertension in Sweden and Minnesota, and to assess to what extent different national guidelines account for differences. DESIGN. Random samples of family physicians were selected for telephone interviews on their practice of hypertension. SETTING. Primary care in southern Sweden and in Minnesota. SUBJECTS. Family medicine speci
