By pulse-modulating a cw dye-laser beam and employing the delayed-coincidence technique, we have determined the natural radiative lifetimes of a number of atomic states in rare-earth atoms Eu, Dy, and Yb. In the measurements, which were performed on an atomic beam, exponential decay curves with good statistics were obtained using short measuring times. The general features of the technique are dis

Examples of Fell algebras with compact spectrum and trivial Dixmier-Douady invariant are constructed to illustrate differences with the case of continuous-trace C∗-algebras. At the level of the spectrum, this translates to only assuming the spectrum is locally Hausdorff (rather than Hausdorff). The existence of (full) projections is the fundamental question considered. The class of Fell algebras s

This collection seeks to illustrate the state of the art in territoriological research, both empirical and theoretical. The volume gathers together a series of original, previously unpublished essays exploring the newly emerging territorial formations in culture, politics and society.While the globalisation debate of the 1990s largely pivoted around a ‘general deterritorialisation’ hypothesis, sin

In this paper, the vascular sounds of the arteriovenous fistula at the anastomosis and five centimeters downstream the anastomosis were analyzed. The analysis of the sounds was based on features extracted from the power spectral density (PSD) and wavelet decomposition. The database consists of 15 recordings at the anastomosis and 15 reference recordings obtained from 15 patients. The results showe

Society is highly dependent on services such as electricity, communication, and transportation. Furthermore, the critical infrastructures (CIs) that provide these services are highly interdependent through a number of physical, economic and organizational links. In this context, a holistic perspective on risk is essential to avoid suboptimal interventions and risk-related blind spots. Here, fragme

In recent decades, there has been a global recognition of the co-constitutive relationship between gender justice and peaceful transformation of previously war-torn societies. This chapter investigates how “women-friendly states” have located their foreign policies within notions of gender equality and empowerment. It focuses on how feminist foreign policy is to all intents and purposes ethical an

Lessons of history are two-sided cultural products. They serve as active instruments of temporal orientation in a society in which historical trajectories seem obsolete and the future open, but they are also passively framed within historical cultures that often have prefigured them. Thus, lessons are seldom arbitrarily constructed. while lessons of history for many centuries were highly esteemed

The aim of these experiments was to obtain a detailed knowledge of how the orbicularis oculi muscle is activated during the execution of a conditioned eyeblink response (CR). This is the first critical step to understand the underlying neural mechanisms involved in the control of the CR. Decerebrate ferrets were trained in a classical conditioning paradigm. The conditioned stimulus (CS) was a trai

Polyclonal protein HC-IgA complexes (HC-IgA) were isolated from two different serum pools. Their hydrodynamic volumes were found to be slightly greater than that of monomeric IgA but less than that of dimeric IgA. Sodium dodecyl sulphate (SDS)-polyacrylamide gel electrophoresis of reduced and carboxymethylated complexes followed by immunoblotting showed that the complexes contained normal light an

The infrared spectra of water dimers formed from H2O, D 2O, and HDO in krypton matrices have been recorded. Thermal equilibria between H- and D-bonded dimers have been studied. D bonding is preferred, and H-bonded dimers are approximately 60 cm-1 less stable than D-bonded dimers. The energy difference seems to be due to the higher value of the intermolecular out-of-plane H-bond shear vibration com

Critical infrastructure such as transportation, power, telecommunication and water supply systems accommodate and enable flows of essential goods and services that modem societies are highly dependent upon. These critical flows connect countries, organizations and communities, and are imperative for upholding vital societal functions. Disruptions of such flows hold the potential of severe and pote
