Transverse momentum spectra for charged hadrons and for neutral pions in the range 1 Gev/c < P-T < 5 GeV/c have been measured by the PHENIX experiment at RHIC in Au + Au collisions at rootS(NN) = 130 GeV. At high p(T) the spectra from peripheral nuclear collisions are consistent with scaling the spectra from p + p collisions by the average number of binary nucleon-nucleon collisions. The spectra f

The microarray technology has revolutionized biological research in the last decade. By monitoring the expression of many genes simultaneously, microarrays can elucidate gene function, as well as scan entire genomes for candidate genes encoding complex traits. However, because of high costs of sequencing and design, microarrays have largely been restricted to a few model species. Cross-species mic

In the kindling model of epilepsy, repeated electrical stimulations lead to progressive and permanent intensification of seizure activity. We find that the development of amygdala kindling is markedly retarded in mice heterozygous for a deletion of the neurotrophin-3 (NT-3) gene (NT-3+/- mice). These mice did not reach the fully kindled state (3rd grade 5 seizure) until after 28 +/- 4 days of stim

Hemicelluloses constitute one of the most abundant renewable resources on earth. To increase their utilization, the isolation of hemicelluloses from industrial biomass side-streams would be beneficial. A method was investigated to isolate hemicelluloses from process water from a thermomechanical pulp mill. The method consists of three steps: removal of solids by microfiltration, preconcentration o

Regional cerebral blood flow (rCBF) was assessed using dynamic susceptibility-contrast MRI at 1.5 T. A simultaneous dual FLASH pulse sequence and Gd-DTPA-BMA (0.3 mmol/kg b.w.) were used for examination of 43 volunteers, measuring rCBF in frontal white matter (WM) and in gray matter in the thalamus (GM). Arterial input functions (AIFs) were registered 1) in the carotid artery and 2) in an artery w

This paper reconsiders the distribution of verb movement in Scandinavian in light of new data from Norwegian and Icelandic. The main claim is that Regional Northern Norwegian displays optional verb movement to the inflectional domain, whereas Icelandic has no independent verb movement at all to this domain, contrary to standard assumptions: All verb movement in Icelandic is to the CP domain of the

Brent geese were tracked by satellite telemetry from spring staging areas in Denmark to Arctic breeding areas in Svalbard and Greenland in 1997 and 2001. From estimated departure masses and carcass analysis we used flight mechnical theory to estimate maximum flight ranges of both sexes, and remaining stores of fat and protein upon arrival in females. Model predictions suggested that all birds but

The relationship between framework design and language constructs are discussed for two reasons: firstly, designing frameworks requires the ability to give the framework designer precise control over aspects of the framework extensions; secondly, the framework constraints should be specified such that they are statically checkable. Four existing language constructs are discussed: generalized block

Previously unknown aspects in the life cycle of the freshwater flagellate Gonyostomum semen (Ehrenb.) (Raphidophyceae) are described here. This species forms intense blooms in many northern temperate lakes, and has increased in abundance and frequency in northern Europe during the past decades. The proposed life cycle is based on observations of life cycle stages and transitions in cultures. Viabl

Recent studies in Drosophila have shown that heparan sulfate proteoglycans (HSPGs) are required for Wingless (Wg/Wnt) signaling. In addition, genetic and phenotypic analyses have implicated the glypican gene daily in this process. Here, we report the identification of another Drosophila glypican gene, daily-like (dly) and show that it is also involved in Wg signaling. Inhibition of dly gene activi

Compared to conventional color Doppler ultrasound imaging, the new color Doppler modality "color Doppler energy" (CDE) has improved the possibility of visualizing blood vessels having low blood-flow velocities, but appears to be influenced by the settings of the ultrasound instrument and motion artefacts. The aim of this methodological study was to evaluate the effects of the different factors on

Several commercially available systems for attenuation correction in single photon emission computed tomography (SPECT) based on a transmission scan have been introduced that vary in performance. A test procedure for attenuation correction in SPECT is described and applied to two principally different gamma camera systems (the Siemens Multispect 3 triple-headed system [3HS] and the ADAC Genesys Ve

Background: Treatment of blunt splenic trauma has undergone dramatic changes over the last few decades. Nonoperative management (NOM) is now the preferred treatment of choice, when possible. The outcome of NOM has been evaluated. This study evaluates the results following the management of blunt splenic injury in adults in a Swedish university hospital with a low blunt abdominal trauma incidence.

[1] Convective available potential energy (CAPE), frequently regarded as an indicator of the potential intensity of deep convection, is strongly controlled by the properties of the planetary boundary layer (BL). Variations in CAPE observed during field experiments in midcontinent North America, the tropical east Atlantic, and the tropical west Pacific, can be accounted for mostly by changes in the

The filamentous fungus Penicillium brasilianum IBT 20888 was cultivated on a mixture of 30 g l−1 cellulose and 10 g l−1 xylan for 111 h and the resulting culture filtrate was used for protein purification. From the cultivation broth, five cellulases and one xylanase were purified. Hydrolysis studies revealed that two of the cellulases were acting as cellobiohydrolases by being active on only micro

Several studies have found a clustering of dementia in relatives of patients with frontotemporal dementia (FTD). This study analysed the familial aggregation of FTD specifically as well as the occurrence of dementia in general in first-degree relatives of patients with FTD. A family history study was carried out on 478 first-degree relatives of 74 index patients suffering from FTD. Cases of organi
