Charm production from the quark-gluon plasma created in the midrapidity of central heavy ion collisions at the Large Hadron Collider (LHC) is studied in the next-to-leading order in QCD. Using a schematic longitudinally boost-invariant and transversally expanding fire-cylinder model, we find that charm production could be appreciably enhanced at LHC as a result of the high temperature that is e...

In Pb-contaminated environments, simultaneous exposure to both waterborne and dietborne Pb is likely to occur. This study examined the potential interactive effects of these two pathways in juvenile rainbow trout that were exposed to Pb in the water alone, in the diet alone, and in combination for 7 weeks. The highest waterborne Pb concentration tested (110μgL(-1)) was approximately equivalent ...

Lead is a toxic heavy metal whose detoxification in organisms is mainly carried out by its coordination with some metalloproteins such as metallothioneins (MTs). Two Pb-MT complexes, named as Pb7-MT2(I) and Pb7-MT2(II), form under neutral and weakly acidic conditions, respectively. However, the structures of the two complexes, which are crucial for a better understanding of the detoxification m...

Recent NA49 results on Λ and φ production in central Pb-Pb collisions at beam energies from 40 to 158 A·GeV are presented. The measurement of strange baryons like Λ(uds), which contain between 30 and 60% of the total strangeness produced, allows to study simultaneously strangeness production and the effect of baryon density in A-A collisions. Essentially half of the ¯ s quarks are contained in ...

The recent discovery of a barbiturate-sensitive "general anesthesia switch" mechanism localized in the rat brain stem mesopontine tegmental anesthesia area (MPTA) has challenged the current view of the nonspecific actions of general anesthetic agents in the CNS. In this study we provide electrophysiological evidence that the antinociception, which accompanies the behavioral state resembling gen...

The aim of this study was to evaluate the role of alloying and rapid solidification processing in direct structural control in lead base batteries. A detailed investigation on rapid quenching of liquid lead base alloys for high performance storage battery applications was made in order to choose suitable lead grid alloys for lead acid batteries as melt-spun ribbons. So this paper provides a com...

Background: Lead (Pb) is one of the most important environmental pollutants that affect the male reproductive system. The aim of this study was to investigate the protective effect of green tea extract on lead-induced oxidative stress, apoptosis and morphometric changes in male mouse epididymis. Materials and Methods: Forty adult male mice were randomly divided into four groups (n= 10), as foll...

This paper overviews the main results on dilepton and heavy flavour production in heavy ion collisions, obtained in measurements done at the CERN SPS, over the last few years. The presently available results are very interesting, indicating the production of a new state of matter in central Pb-Pb collisions at SPS energies. However, important questions remain open. New and improved measurements...

We present geochronological evidence in the eastern Himalayan syntaxis (Namche Barwa) for high-pressure (HP) granulite-facies metamorphism and explain its importance for understanding both the deep continental subduction of the Indian plate beneath Asia and its subsequent exhumation. The timing of peak and retrograde metamorphism in part constrains these processes but is debated. We present zir...

The ATLAS detector is capable of resolving the highest energy pp collisions at luminosities sufficient to yield 10’s of simultaneous interactions within a bunch collision lasting <0.5 nsec. Already in 2011 a mean occupancy of 20 is often found in pp running. In 2004 studies by ATLAS showed that the detector would have excellent performance also for the foreseeable particle multiplicities in the...
