This paper suggests that the Payne models should not properly be regarded as the traffic flow analog of the Navier-Stokes equations of fluid dynamics. Further, the Chapman-Enskog asymptotic expansion in a small parameter is shown to lead to an alternate class of models that seem to have a more legitimate claim to that distinction. Details of this expansion, about the stable-flow equilibria of the

A modified ELISA assay for measurement of the two estrogen metabolites 2-hydroxyestrone (2OHE1) and 16 alpha-hydroxyestrone (16 alpha OHE1) in plasma and serum has been developed. Previously, these have only been measured in urine. It is not known how well the measurements of these metabolites in urine and plasma are correlated. The goal of this study was to compare urinary and plasma levels of 2O

BACKGROUND: The Collaborative Group on Hormonal Factors in Breast Cancer has brought together the worldwide epidemiological evidence on the possible relation between breast cancer and previous spontaneous and induced abortions. METHODS: Data on individual women from 53 studies undertaken in 16 countries with liberal abortion laws were checked and analysed centrally. Relative risks of breast cancer

A fully integrated digitally controlled PLL used as a clock multiplying circuit is designed and fabricated. The PLL has no off-chip components and it is made from standard cells found in most digital standard cell libraries. It is therefore portable between processes as an IP-block. Using a 0.35 μm standard CMOS process and a 3.0 V supply, the PLL has a frequency range of 152 MHz to 366 MHz and oc

Semiconductor devices are heavily dependent on dopant incorporation in order to control the electrical properties. In this paper we investigate the possibility of using gates wrapped around a nanowire (NW) channel as a way of tuning the Fermi level position, in certain cases removing the need for dopants and providing a more dynamical way of setting the device properties. InP NW devices with omega

We present a variation of fractional tessellation to provide more uniformly distributed tessellation in screen space. Tessellation weights are added at the vertices for added flexibility and we show that the quality is improved at a minor cost.

Internal erosion is one of the major reasons for embankment dam failures. Despite this, the knowledge of the temporal development of internal erosion in full scale structures is limited. Results from a research field monitoring program by daily resistivity measurements in Sweden clearly show long term changes in resistivity in the embankment dam. The results indicate that resistivity monitoring ca

The following article is an interpretation of a narrative in Theodoret of Cyrrhus’ collective biography about the history of the monks of Syria, the Philotheos historia. The most well-known saint of Theodoret’s own diocese was James of Cyrrhestica. His biography has a central place in the PH, but has not received as much attention as that of his name- sake James of Nisibis, or Symeon the Stylite.

The use of service oriented architectures (SOA) is rapidly penetrating contemporary business life based on the promise of scalable and flexible information infrastructures. However the technique is still in it infancy and many questions regarding the consequences of a shift towards this kind of IT architecture still remains unanswered. We approach the relation between SOA and another actual topic,
