Middle and Upper Ordovician graptolites, trilobites, and biostratigraphy of Scania and Jämtland, Sweden

Graptolites and some trilobites from Middle–Upper Ordovician siliciclastic and calcareous rocks in Scania (Skåne), southern Sweden, and Jämtland, central Sweden, are described and discussed. Their stratigraphic distribution is discussed on the basis of new and old collections from outcrops and drill cores. The uppermost Middle–Upper Ordovician of Scania consists predominantly of mudstones and dark

International growth through cooperation: Brand-driven strategies, leadership, and career development in Sweden

Corporate growth is often viewed as being either internally generated or externally achieved through mergers and acquisitions (M&As). During the last decade, strategic alliances have become an increasingly popular third alternative to either internal or acquired growth. Alliances can be cheaper, more flexible, and faster than internal or M&A growth. However, they suffer from a major drawba

Ponderomotive shearing for spectral interferometry of extreme-ultraviolet pulses

We propose a novel method for completely characterizing ultrashort pulses at extreme-ultraviolet (XUV) wavelengths by adapting the technique of spectral phase interferometry for direct electric-field reconstruction to this spectral region. Two-electron wave packets are coherently produced by photoionizing atoms with two time-delayed replicas of the XUV pulse. For one of the XUV pulses, photoioniza

New technologies to replace current blood typing reagents.

Purpose of review This review summarizes recent developments in blood grouping and compatibility testing in transfusion medicine. Recent findings Identification of the molecular characteristics of the major human blood groups has provided an opportunity to develop methods for blood group phenotyping using DNA-based technology. Various studies have demonstrated the feasibility of such an approach a

Effects of inclination angle of ribs on the flow behavior in rectangular ducts

The flow behavior in rib-roughened ducts is influenced by the inclination of ribs and the effect is investigated in the present study by Particle Image Velocimetry (PIV). The local flow structures between two adjacent ribs were measured. The Reynolds number was fixed at 5800. The flow field description was based on the PIV results in planes both parallel and perpendicular to the ribbed walls at va

Reactors - Circuit Theory and Silicon Integrated Applications

This dissertation deals with reactive components in electric circuits, both as targets for a theoretical circuit analysis, and as devices implemented in silicon processes like CMOS. The frequency behavior of a general electric network is determined by the reactances (i.e., inductances and capacitances) present in the network, either as intentional parts of the design, or as process and implementa

Simulation of Phosphorus, Zinc and Cadmium Mass Flow in Dairy Farming Systems

Popular Abstract in Swedish En simuleringsmodell, FARMFLOW, utvecklades för att beräkna förråd, flöden och balanser av fosfor (P), zink (Zn) och kadmium (Cd) på mjölkgårdar. De simulerade kontinuerliga förändringarna av ämnesförråden gör det möjligt att utvärdera de långsiktiga effekterna av olika skötselstrategier. Fältdata från en svensk försöksgård, Öjebyn, användes för att parameterisera FARMFA simulation model, FARMFLOW, was developed for the calculation of phosphorus (P), zinc (Zn) and cadmium (Cd) stocks, flows and balances in different parts of a dairy farming system. The simulated continuous change in element stocks within the farming system enables evaluation of the long-term effects of management practices. The FARMFLOW model reproduces feedback mechanisms of the internal cyclin

Subjective recording of fetal movements. I. Limits and acceptability in normal pregnancies

Maternal counting of fetal movements is increasingly used as a clinical method for assessment of fetal health. The present study established normal limits for two methods of subjective fetal movement recording. Four hundred-and-seventeen randomly selected women with low-risk pregnancies recorded the time necessary for 10 fetal movements every morning and also the number of fetal movements during 1

Is a nappy change stressful to neonates?

Objectives: Infants in neonatal intensive care (NICU infants) are often cared for in a stressful environment that includes potentially painful or stressful interventions. The aim was to investigate whether NICU infants have different pattern of stress and pain responses than healthy newborns when challenged by a non-painful everyday care routine. Methods: NICU infants born at 23-38 weeks gestation

Fruits of Capitalism, Modernisation of Chilean Agriculture 1950-2000

Popular Abstract in Swedish Det så kallade Chilenska ekonomiska undret under 1980- och 1990-talet är resultatet av en omfattande strukturförändring av den Chilenska ekonomin. I denna omvandling har jordbrukets modernisering och kapitalisering spelat en mycket viktig roll.Huvudfåran i den akademiska debatten har hittills huvudsakligen förklarat omvandlingen genom tillämpning av olika policy instrumThe so-called Chilean economic miracle during the 1980s and 1990s connotes not only high-speed economic growth but also a profound structural transformation of the Chilean economy. Most previous research ascribes growth and transformation to the liberalisation of markets and other neo-liberal policy instruments introduced after 1974. Policies, before as well as after 1974, have indeed been importa

Localization of the initial fibrillatory cycle in patients with paroxysmal atrial fibrillation

BACKGROUND: Recent reports suggest the presence of conduction delay in the posterior septal region during sinus rhythm in patients with lone paroxysmal atrial fibrillation (AF). OBJECTIVE: To explore the location of intra-atrial conduction delay associated with initiation of AF. DESIGN: In 8 lone AF patients (51 +/- 10 years), 20 AF paroxysms were induced during electrophysiological examination. B
