We present azimuthal anisotropy measurements in Au+Au and Cu+Cu collisions at and 200 GeV. Comparison between reaction plane and cumulant v2 measurements in Au+Au collisions at GeV shows that non-flow contributions, originating mainly from jets, influence the extracted v2 for pT 3.5 GeV/c. Number of constituent quark (NCQ) scaling of v2, when studied as a function of transverse kinetic energy KET,

BACKGROUND: There are two principal types of group O alleles; deletional alleles feature 261delG leading to nonfunctional truncated protein. Nondeletional alleles have the consensus guanosine at residue 261. The major nondeletional allele, O-2, encodes full-length protein with Gly268Arg. While reports vary, O-2 has been proposed to encode weakly functional A-glycosyltransferase (GTA). The main obj

Background: Cyclin D1 is a well-characterised cell cycle regulator with established oncogenic capabilities. Despite these properties, studies report contrasting links to tumour aggressiveness. It has previously been shown that silencing cyclin D1 increases the migratory capacity of MDA-MB-231 breast cancer cells with concomitant increase in 'inhibitor of differentiation 1' (ID1) gene expression. I

Background: Resolving threats to widely distributed marine megafauna requires definition of the geographic distributions of both the threats as well as the population unit(s) of interest. In turn, because individual threats can operate on varying spatial scales, their impacts can affect different segments of a population of the same species. Therefore, integration of multiple tools and techniques

Comparative studies of corruption focus on the selection and incentives of policymakers. With few exceptions, actors who are in charge of implementing policies have been neglected. This article analyzes an original data set on the bureaucratic features and its effects on corruption in fifty-two countries. Two empirical findings challenge the conventional wisdom in literature. First, certain bureau

The interaction among two spheres in tandem formation are studied for a Reynolds number of 300 using both steady and pulsating inflow conditions. The purpose is to further investigate the force characteristics as well as the shedding patterns of the two spheres as the separation distance is changed from 1.5 to 12. sphere diameters. The method used for the simulations is the volume of solid (VOS) m

This contribution highlights recent results from the PHENIX Collaboration at RHIC. It covers global variables, flow and 2-particle correlations. A second contribution in this issue, by T C Awes (2008 J. Phys. G: Nucl. Part. Phys. 35 104007), covers PHENIX results on heavy quarks, leptons and photons.

Ljud och tystnad för sinne och själ - om betydelser av ljud och tystnad för själslig och mental rekreation (seminarium 28 november 2008) Innehåll: Henrik Karlsson: Om tystnaden får tala, Owe Wikström: Vad tyst det blev!, Håkan Svenbro: Meditation över tystnad, Antoon Geels: Tystnadens röst och själens musik.

The nature of size fluctuations is crucial in forecasting future population persistence, independently of whether the variability stems from external forces or from the dynamics of the population renewal process. The risk of intercepting zero is highly dependent on the way the variance of the population size relates to its mean. The minimum population size required for a population not to go extin

Flying animals are capable of navigating through environments of different complexity with high precision. To control their flight when negotiating narrow tunnels, bees and birds use the magnitude of apparent image motion (known as optic flow) generated by the walls. In their natural habitat, however, these animals would encounter both cluttered and open environments. Here, we investigate how larg

Studies on dissolved silicate (DSi) and biogenic silica (BSi) dynamics were carried out in the Oder estuary, Baltic Sea in 2000-2005. The Oder estuary proved to be an important component of the Oder River-Baltic Sea continuum where very intensive seasonal DSi uptake during spring and autumn, but also BSi regeneration during summer take place. Owing to the regeneration process annual DSi patterns i

Power failures in combination with harsh weather conditions during recent years have led to an increased focus on a safe energy supply to our society. Many vital functions are dependent on electricity; e.g., lighting, telephony, medical equipment, lifts, alarm systems, payment, pumps for town's water and, perhaps the most critical of all. heating systems. In Sweden. district heating (DH) is the mo
