The aim of this ongoing study was to evaluate the specific energy absorption rate (SAR) values in the body of a person present near-fixed readers of ultra-high frequency (UHF) radio frequency identification (RFID) passive tags incorporated in real-time locating systems (RTLS), operating at a frequency range of 865–868 MHz, considering various exposure scenarios. The modelled electromagnetic field (EMF) source was a rectangular microstrip antenna designed at resonance frequency in free space at 865 MHz. The SAR values in the body exposed to EMF 5 cm away from the UHF RFID readers need consideration with respect to general public exposure limits, when the radiated power exceeds 8 W.

The aim of this study was to model and evaluate the Specific Energy Absorption Rate (SAR) values in humans in proximity to fixed multi-antenna I-RFID readers of passive tags under various scenarios mimicking exposure when they are incorporated in Real-Time Location Systems (RTLS), or used to monitor Personal Protective Equipment (PPE). The sources of the electromagnetic field (EMF) in the modelled readers were rectangular microstrip antennas at a resonance frequency in free space of 866 MHz from the ultra-high frequency (UHF) RFID frequency range of 865–868 MHz. The obtained results of numerical modelling showed that the SAR values in the body 5 cm away from the UHF RFID readers need consideration with respect to exposure limits set by international guidelines to prevent adverse thermal effects of exposure to EMF: when the effective radiated power exceeds 5.5 W with respect to the general public/unrestricted environments exposure limits, and with respect to occupational/restricted environments exposure limits, when the effective radiated power exceeds 27.5 W.

Two Factors

SummaryFactor VIII occurs in the body in two different forms. In lymph factor VIII is bound to chylomicra. In plasma, factor VIII is bound to a protein.After delipidation of chylomicra we obtained a glycoprotein with a high polysaccharide content and a molecular weight of approx. 160,000.In plasma, factor VIII is attached to a protein which is present in normal concentrations in plasma of patients with haemophilia A and in serum (co-factor VIII).This factor is deficient in both the plasma and the serum of patients with von Willebrand’s disease.The binding between factor VIII and co-factor VIII is reversible.Some properties of these two factors are described.

The Sober Bacchae: Dance as Phenomenal Limitation in Nietzsche

This essay seeks to dispel entrenched critical opinion regarding dance across Nietzsche's writings as representative of Dionysian intoxication alone. Taking as its prompt the riposte of Alain Badiou, ‘Nietzsche is miles away from any doctrine of dance as a primitive ecstasy’ and ‘dance is in no way the liberated bodily impulse, the wild energy of the body’, the essay uncovers the ties between dance and Apollo in the Nietzschean theory of art while qualifying dance's relation to Dionysus. Primarily through an analysis of The Dionysiac World View and The Birth of Tragedy, the essay seeks to illuminate enigmatic statements about dance in Nietzsche (‘in dance the greatest strength is only potential, although it is betrayed by the suppleness of movement’ and ‘dance is the preservation of orderly measure’). It does this through an elucidation of the specific function of dance in Nietzsche's interpretation of classical Greece; via an assessment of the difficulties associated with the Nietzschean understanding of the bacchanal; and lastly through an analysis of Nietzsche's characterization of dance as a symbol. The essay culminates in a discussion of dance's ties to Nietzschean life affirmation; here the themes of physico-phenomenal existence, joy and illusion in Nietzsche are surveyed.

AbstractElectromigration experiments have been carried out on simple Cu dual-damascene interconnect tree structures consisting of straight via-to-via (or contact-to-contact) lines with an extra via in the middle of the line. As with Al-based interconnects, the reliability of a segment in this tree strongly depends on the stress conditions of the connected segment. Beyond this, there are important differences in the results obtained under similar test conditions for Al-based and Cu-based interconnect trees. These differences are thought to be associated with variations in the architectural schemes of the two metallizations. The absence of a conducting electromigrationresistant overlayer in Cu technology, and the possibility of liner rupture at stressed vias lead to significant differences in tree reliabilities in Cu compared to Al.
