Strangeness Production in Au--Au collisions at sNN=62.4\sqrt{s_{NN}}=62.4 GeV

We obtain strangeness production as function of centrality in a statistical hadronization model analysis of all experimental hadron production data in Au--Au collisions at \sqrt{s_{NN}}=62.4\GeV. Our analysis describes successfully the yield of strange and multi-strange hadrons recently published. We explore condition of hadronization as a function of centrality and find universality for the case of chemical non-equilibrium in the hadron phase space corresponding to quark--gluon plasma (QGP) in chemical equilibrium.Comment: 6 pages, 2 figures, proceedings for SQM 2011 conferenc

Correctional Officers\u27 Perceptions of Working with Inmates with Mental Illnesses and the Effectiveness of Mental Health Training

Many correctional officers have voiced not receiving adequate training in mental health and how to best work with inmates who may be experiencing mental health symptoms. Crisis Intervention Team (CIT) training has improved officers’ responses to working with individuals during a mental health crisis The purpose of this project was to examine correctional officers’ perceptions of working with inmates with mental illnesses and how prepared they feel working with inmates who are in crisis. Seventy correctional officers were surveyed in two county jails in Minnesota. The sample of participants included officers who have been certified in CIT. Results were analyzed using descriptive and inferential statistics. While findings indicated there were no differences in perceptions of inmates with mental illnesses between correctional officers certified in CIT and correctional officers who were not, correctional officers who were certified in CIT self-reported they felt more prepared to work with inmates experiencing mental health symptoms and inmates who were in crisis. A third finding demonstrated correctional officers who indicated they were prepared to work with these inmates also had more positive perceptions of them. The participants surveyed were unrepresentative across gender and race. Conducting further research will help gain a better understanding on the views correctional officers have towards mental illnesses and responding to inmates who have mental illnesses, or who are in crisis

The effects of boron and in vitro propagation stress on the morphological and physiological development of broccoli

Boron deficient broccoli plants produce small heads and develop stress symptoms which reduce the marketability of the head. Although the losses in productivity of broccoli due to boron deficiency have been well-documented, the changes in the morphological and physiological development of boron deficient broccoli plants have not been thoroughly examined. The purposes of this project were to examine the influence of boron on the development of broccoli plants and broccoli leaf explants, and to evaluate the potential of using in vitro propagation as a means of regenerating broccoli plants for use in commercial production. Boron deficient broccoli plants developed deformed young leaves which had reduced chlorophyll levels and low stomatal conductance and transpiration rates. Boron deficiency induced stress symptoms which included scaling of the stalk epidermis, increased phenolic compound and fiber content of the head, and pith deformation. Symptoms of boron deficiency were less severe in plants which were more efficient in boron uptake. Broccoli plants grown in toxic concentrations of boron had chlorotic leaf margins, reduced chlorophyll content, and low rates of net photosynthesis. However, these plants developed larger heads, which may suggest that the boron demand of developing broccoli heads is not met when plants are grown in non-toxic levels of boron. Boron deficiency enhanced auxin-stimulated ethylene production, while suppressing root initiation of broccoli leaf explants. Ethylene blocker and promoter studies indicated that the reduction in root initiation was not caused by enhanced ethylene production. Broccoli plants regenerated from buds were smaller and matured sooner than seed grown plants. Concentration of harvest and uniformity of head size were not improved through clonal propagation. Further, the frequent occurrence of somaclonal variation may limit the commercial use of in vitro propagation

Hadron production and QGP Hadronization in Pb--Pb collisions at sNN=2.76\sqrt{s_{NN}}=2.76 TeV

We show that all central rapidity hadron yields measured in Pb--Pb collisions at $\sqrt{s_{NN}}=2.76$ TeV are well described by the chemical non-equilibrium statistical hadronization model (SHM), where the chemically equilibrated QGP source breaks up directly into hadrons. SHM parameters are obtained as a function of centrality of colliding ions, and we compare CERN Large Hadron Collider (LHC) with Brookhaven National Laboratory Relativistic Heavy Ion Collider (RHIC) results. We predict yields of unobserved hadrons and address anti-matter production. The physical properties of the quark--gluon plasma fireball particle source show universality of hadronization conditions at LHC and RHIC.Comment: 22 pages, 16 figures, 6 table

Beam test results of the irradiated Silicon Drift Detector for ALICE

The Silicon Drift Detectors will equip two of the six cylindrical layers of high precision position sensitive detectors in the ITS of the ALICE experiment at LHC. In this paper we report the beam test results of a SDD irradiated with 1 GeV electrons. The aim of this test was to verify the radiation tolerance of the device under an electron fluence equivalent to twice particle fluence expected during 10 years of ALICE operation.Comment: 6 pages,6 figures, to appear in the proceedings of International Workshop In high Multiplicity Environments (TIME'05), 3-7 October 2005, Zurich,Switzerlan
