After more than four decades of presence in the manufacturing industry, discrete event simulation has established itself as a powerful technology for a wide range of strategic, tactical, and operational applications in production, logistics, and supply chain management. Discrete event simulation software packages - although not entirely adequate - are relatively capable, and methodologies for perf

The Proton Exchange Membrane (PEM) fuel cell has been investigated for a long time because it has a high power density, low emission, wide choice of fuel sources, etc. However, the performance of a stack of PEM cells degrades with respect to that of a single cell. This is mainly due to the introduction of the manifold in which supplies the reactants to individual cells. The manifold can induce an

TiO2(B) was used as a support for vanadium oxide with loadings in the range 1/4 to 10 theoretical layers. The vanadium could be separated into two parts, which were soluble and insoluble in NH3(aq), respectively. Insoluble vanadium, in an amount corresponding to a complete monolayer at high loadings, was present as V4+ in freshly prepared catalysts. Diffuse reflectance FTIR spectroscopy was used t

The Hipparcos mission (1989-1993) resulted in the first space-based stellar catalogue including measurements of positions, parallaxes and annual proper motions accurate to about one milli-arcsecond. More space astrometry missions will follow in the near future. The ultra-small Japanese mission Nano-JASMINE (launch in late 2013) will determine positions and annual proper motions with some milli-arc

Under the Leonardo da Vinci – Lifelong Learning Programme (LLP) – there is a sub-programme, Transfer of Innovation (ToI). ToI is funding projects which further develop previous project outcomes. This paper deals with a new pilot project under ToI, eGIS+, which has received funding for two years (2007 – 2009). eGIS+ further develop a previous pilot project, E-GIS (European Level Developments of Fle

This chapter describes tonal features of Halh Mongolian. Mongolian belongs to edge-prominence languages: Halh speakers either use available boundary tones or insert a tonal boundary for different pragmatic meanings. Most tonal variation occurs utterance finally, while phrasing and focusing are signaled phrase initially at the left edge of prosodic units.

The thesis is focused on two major subjects: - Calculation of free energy is of great help in the study of any molecular system. The free energy determines phase behaviour of colloids and polymer solutions. It also controls the conformational properties of single macromolecules, e.g. DNA, proteins, copolymers. One of the most robust computer simulation techniques for free energy estimation is an

Popular Abstract in Swedish Proteiner är uppbyggda av aminosyror som är hopkopplade med varandra och bildar långa kedjor som kan bestå av hundra- eller tusentals aminosyror. Det finns en mängd olika proteiner och de har många olika funktioner. I studierna som beskrivs här, har proteiner som finns på ytan av vissa bakterier studerats. De långa proteinkedjorna i dessa bakteriella ytproteiner är oftPeptostreptococcus magnus and group C/G streptococci are Gram-positive cocci that are part of the normal flora and reside in more or less the same locations in the host. Protein G of group C/G streptococci was originally described as binding IgGFc of several species and later shown to also bind human serum albumin and albumins from various animal species. From albumin-binding strains of P. magnus

The purpose of the IAU Meteor Data Center is to archive, document anddisseminate information on meteoroid orbits. At present 4581 preciselyreduced photographic recordings, 1425 video recordings and 63330 radardetermined orbits are archived at the center.

The chapter traces the development of the international response to the pandemic of HIV/AIDS from the designation of the World Health Organization (WHO) as “lead agency” in the late 1980s to the emergence of a variety of public-private partnerships from the 1990s onwards. This trajectory is related to general trends in global public health governance. Existing partnerships in the field of HIV/AIDS

There is a rhetoric in current European political agenda for widening access to ICT’s as part of a strategy for encouraging greater participation in public life. We argue against a naïve assumption that technology in itself could provide solutions. Knowing that systems with potential for meaningful use are available is a necessary, but not sufficient, condition to bring about desire for use in any
