The supermassive black holes (SMBHs) massive enough (& few×10M⊙) to power the bright redshift z ≈ 6 quasars observed in the Sloan Digital Sky Survey (SDSS) are thought to have assembled by mergers and/or gas accretion from less massive “seed” BHs. If the seeds are the ∼ 10M⊙ remnant BHs from the first generation of stars, they must be in place well before redshift z = 6, and must avoid being ej...

The best evidence for mass discrepancies in galaxies comes from rotation curves of neutral hydrogen. However, in the case of our own Galaxy, the rotation curve cannot be traced beyond ∼ 20 kpc. It is the kinematics of stellar tracers of the distant halo – namely the bound dwarf galaxy satellites and distant globular clusters – that provide the mass estimates. The most recent analysis 1 found th...

The effect of Pistacia lentiscus L. leaf extracts (aqueous, 30% ethanol and 70% ethanol) was studied on the rat isolated trachea. Pistacia lentiscus L. extracts induced a relaxation on basal tone and precontracted trachea. On the rat isolated trachea precontracted by acetylcholine 10M, Pistacia lenticus L. leaf extracts (aqueous, 30% ethanol and 70% ethanol) induced a relaxation. EC 50 values f...

We compute the properties of dark matter halos with mass 10 − 10M⊙ at redshift z = 6 − 11 in the standard cold dark matter cosmological model, utilizing a very high resolution N-body simulation. We find that dark matter halos in these mass and redshift ranges are significantly biased over matter with a bias factor in the range 2− 6. The dark matter halo mass function displays a slope of 2.05±0....

We use the Updated Zwicky Catalog of galaxies (Falco et al. 1999) to generate a catalog of groups, by means of a friend-of-friend algorithm. The groups identified have 4 or more members and a surrounding density contrast, δρ/ρ = 80. They cover the region −4 < δ < 90, |b| > 20 spanning over the radial velocity range of 2000 km s < cz < 15000 km s. The total sample (hereafter GUZC) comprises 517 ...

OBJECTIVE The diagnosis of bipolar spectrum disorders (BPSDs [bipolar I and II disorders, cyclothymic disorder, and bipolar disorder not otherwise specified]) in youth remains controversial. The present study evaluated the possibility that the presence of persistent manic symptoms over a relatively short interval may increase the probability of a BPSD DSM diagnosis. METHOD Data were obtained ...

We present high-resolution VLA observations of the molecular gas in the host galaxy of the highest redshift quasar currently known, SDSS J1148+5251 (z=6.42). Our VLA data of the CO(3–2) emission have a maximum resolution of 0.17×0.13 (≤1 kpc), and enable us to resolve the molecular gas emission both spatially and in velocity. The molecular gas in J1148+5251 is extended to a radius of 2.5 kpc, a...

The aim of the present study was twofold. The first aim was to examine the influence of absolute and relative lower body muscle force on kinematic component which determine the start performance. The second aim was to create multiregressional model which could use as a tool for swimming coaches with the purpose to start performance control and improvement. Twenty seven high-level trained male c...
