Identified particle production, azimuthal anisotropy, and interferometry measurements in Au plus Au collisions at root s(NN)=9.2 GeV

We present the first measurements of identified hadron production, azimuthal anisotropy, and pion interferometry from Au + Au collisions below the nominal injection energy at the BNL Relativistic Heavy-Ion Collider (RHIC) facility. The data were collected using the large acceptance solenoidal tracker at RHIC (STAR) detector at root s(NN) = 9.2 GeV from a test run of the collider in the year 2008. Midrapidity results on multiplicity density dN/dy in rapidity y, average transverse momentum < p(T)>, particle ratios, elliptic flow, and Hanbury-Brown-Twiss (HBT) radii are consistent with the corresponding results at similar root s(NN) from fixed-target experiments. Directed flow measurements are presented for both midrapidity and forward-rapidity regions. Furthermore the collision centrality dependence of identified particle dN/dy, < p(T)>, and particle ratios are discussed. These results also demonstrate that the capabilities of the STAR detector, although optimized for root s(NN) = 200 GeV, are suitable for the proposed QCD critical-point search and exploration of the QCD phase diagram at RHIC.

Reaction cross sections for (8)B, (7)Be, and (6)Li+(58)Ni near the Coulomb barrier: Proton-halo effects

Elastic scattering of (8)B, (7)Be, and (6)Li on a (58)Ni target has been measured at energies near the Coulomb barrier. Optical-model fits were made to the experimental angular distributions, and total reaction cross sections were deduced. A comparison with other systems provides striking evidence for proton-halo effects on (8)B reactions. As opposed to the situation for the neutron-halo nucleus (6)He, for which particle transfer dominates, the ""extra"" cross section observed for (8)B appears to result entirely from projectile breakup.

Internal Residual Stresses in Sintered and Commercial Low Expansion Li(2)O-Al(2)O(3)-SiO(2) Glass-Ceramics

We performed Synchrotron X-ray diffraction (XRD) analyses of internal residual stresses in monolithic samples of a newly developed Li(2)O-Al(2)O(3)-SiO(2) (LAS) glass-ceramic produced by sintering and in a commercial LAS glass-ceramic, CERAN (R), produced by the traditional crystal nucleation and growth treatments. The elastic constants were measured by instrumented indentation and a pulse-echo technique. The thermal expansion coefficient of virgilite was determined by high temperature XRD and dilatometry. The c-axis contracts with the increasing temperature whereas the a-axis does not vary significantly. Microcracking of the microstructure affects the thermal expansion coefficients measured by dilatometry and thermal expansion hysteresis is observed for the sintered glass-ceramic as well as for CERAN (R). The measured internal stress is quite low for both glass-ceramics and can be explained by theoretical modeling if the high volume fraction of the crystalline phase (virgilite) is considered. Using a modified Green model, the calculated critical (glass) island diameter for spontaneous cracking agreed with experimental observations. The experimental data collected also allowed the calculation of the critical crystal grain diameters for grain-boundary microcracking due to the anisotropy of thermal expansion of virgilite and for microcracking in the residual glass phase surrounding the virgilite particles. All these parameters are important for the successful microstructural design of sintered glass-ceramics.

Based on general concepts relating to risk perception, the authors summarize in this article today's knowledge of smoking risk perception. A pluridisciplinary approach (general internal medicine, public health and anthropology) allows an improved understanding of its complexity, its utility in every day clinical practice and of the questions still pending around its use and evaluation in research projects.

Régulation de la proprotéine convertase subtilisine / kexine type 9 (PCSK9) dans les cellules intestinales Caco-2/15

La proprotéine convertase subtilisine/kexine type 9 (PCSK9) favorise la dégradation post-transcriptionnelle du récepteur des lipoprotéines de faible densité (LDLr) dans les hépatocytes et augmente le LDL-cholestérol dans le plasma. Cependant, il n’est pas clair si la PCSK9 joue un rôle dans l’intestin. Dans cette étude, nous caractérisons les variations de la PCSK9 et du LDLr dans les cellules Caco-2/15 différentiées en fonction d’une variété d’effecteurs potentiels. Le cholestérol (100 µM) lié à l’albumine ou présenté en micelles a réduit de façon significative l’expression génique (30%, p<0,05) et l’expression protéique (50%, p<0,05) de la PCSK9. Étonnamment, une diminution similaire dans le LDLr protéique a été enregistrée (45%, p<0,05). Les cellules traitées avec le 25-hydroxycholestérol (50 µM) présentent également des réductions significatives dans l’ARNm (37%, p<0,01) et la protéine (75%, p<0,001) de la PCSK9. Une baisse des expressions génique (30%, p<0,05) et protéique (57%, p<0,01) a également été constatée dans le LDLr. Des diminutions ont aussi été observées pour la HMG CoA réductase et la protéine liant l’élément de réponse aux stérols SREBP-2. Il a été démontré que le SREBP-2 peut activer transcriptionnellement la PCSK9 par le biais de la liaison de SREBP-2 à son élément de réponse aux stérols situé dans la région proximale du promoteur de la PCSK9. Inversement, la déplétion du contenu cellulaire en cholestérol par l’hydroxypropyl-β-cyclodextrine a augmenté l’expression génique de la PCSK9 (20%, p<0,05) et son contenu protéique (540%, p<0,001), en parallèle avec les niveaux protéiques de SREBP-2. L’ajout des acides biliaires taurocholate et déoxycholate dans le milieu apical des cellules intestinales Caco-2/15 a provoqué une baisse d’expression génique (30%, p<0,01) et une hausse d’expression protéique (43%, p<0,01) de la PCSK9 respectivement, probablement via la modulation du FXR (farnesoid X receptor). Ces données combinées semblent donc indiquer que la PCSK9 fonctionne comme un senseur de stérols dans le petit intestin.

Extração de metais (K, Mg, Ba, Ca, Cr, Mn, Li, Fe) de água produzida utilizando sistema microemulsionado

The produced water is a byproduct formed due to production of petroleum and carries with it a high amount of contaminants such as oil particles in suspension, organic compounds and metals. Thus, these latter pollutants are very difficult to treat because of its high solubility in water. The objective of this work is to use and evaluate a microemulsioned system to remove metals ( K , Mg , Ba , Ca , Cr , Mn , Li , Fe ) of synthetic produced water. For the extraction of metals, it was used a pseudoternary diagram containing the following phases: synthetic produced water as the aqueous phase (AP), hexane as organic phase (OP), and a cosurfactant/surfactant ratio equal to four (C/S = 4) as the third phase, where the OCS (saponified coconut oil) was used as surfactant and n-butanol as cosurfactant. The synthetic produced water was prepared in a bench scale and the region of interest in the diagram for the removal of metals was determined by experimental design called. Ten points located in the phase Winsor II were selected in an area with a large amount of water and small amounts of reagents. The samples were analyzed in atomic absorption spectrometer, and the results were evaluated through a statistical assesment, allowing the efficiency analysis of the effects and their interactions. The results showed percentages of extraction above 90% for the metals manganese, iron, chromium, calcium, barium and magnesium, and around 45% for metals lithium and potassium. The optimal point for the simultaneous removal of metals was calculated using statistical artifact multiple response function (MR). This calculation showed that the point of greatest extraction of metals occurs was the J point, with the composition [72% AP, 9% OP, 19% C/S], obtaining a global extraction percentage about 80%. Considering the aspects analyzed, the microemulsioned system has shown itself to be an effective alternative in the extraction of metals on synthetic produced water remediation
