Diffusion-limited deposition of dipolar particles

Deposits of dipolar particles are investigated by means of extensive Monte Carlo simulations. We found that the effect of the interactions is described by an initial, non-universal, scaling regime characterized by orientationally ordered deposits. In the dipolar regime, the order and geometry of the clusters depend on the strength of the interactions and the magnetic properties are tunable by controlling the growth conditions. At later stages, the growth is dominated by thermal effects and the diffusion-limited universal regime obtains, at finite temperatures. At low temperatures the crossover size increases exponentially as T decreases and at T=0 only the dipolar regime is observed.Comment: 5 pages, 4 figure

Effects of LatticeQCD EoS and Continuous Emission on Some ObseErvables

Effects of lattice-QCD-inspired equations of state and continuous emission on some observables are discussed, by solving a 3D hydrodynamics. The particle multiplicity as well as v2 are found to increase in the mid-rapidity. We also discuss the effects of the initial-condition fluctuations.Comment: 6 pages, 10 figures, prepared for Workshop on Particle Correlations and Fentoscopy, Kromeriz (Czech Republic), Aug. 15-17,200

NeXSPheRIO results on elliptic flow at RHIC and connection with thermalization

Elliptic flow at RHIC is computed event-by-event with NeXSPheRIO. Reasonable agreement with experimental results on $v_2(\eta)$ is obtained. Various effects are studied as well: reconstruction of impact parameter direction, freeze out temperature, equation of state (with or without crossover), emission mecanism.Comment: Contribution to the Proceedings of the Quark-Gluon Plasma Thermalization workshop.

Global Ultrasound Check for the Critically lll (GUCCI)-a new systematized protocol unifying point-of-care ultrasound in critically ill patients based on clinical presentation

Ultrasound technology is an essential tool in the management of critically ill patients. Point-of-care ultrasonography (POCUS) enables data collection from different anatomic areas to achieve the most probable diagnosis and administer the right therapy at the right time. Despite the increasing utilization of POCUS, there is still a lack of standards to establish how to use different bedside ultrasound protocols, and it is imperative to develop a unifying protocol. Thus, the aim of this paper is to establish a new systematized approach that can be adopted by all physicians to implement POCUS for critically ill patient management. To achieve this, we propose a new systematized approach-Global Ultrasound Check for the Critically Ill (GUCCI)-that integrates multiple protocols. This protocol is organized based on three syndromes (acute respiratory failure, shock, and cardiac arrest) and includes ultrasound-guided procedures.info:eu-repo/semantics/publishedVersio

Competitive biosorption of ortho-cresol, phenol, chlorophenol and chromium(VI) from aqueous solution by a bacterial biofilm supported on granular activated carbon

A biofilm of Arthrobacter viscosus supported on granular activated carbon was used to remove chromium and organic compounds (chlorophenol, phenol and o-cresol) from aqueous solutions. The compounds were studied as single solutes and in different combinations between them and Cr(VI). Optimum Cr(VI) adsorption was observed at a phenol concentration of 100 mg/l and at an initial concentration of the metal of 60 mg/l. The maximum values of biosorption of organic compounds were 9.94 mg/g for phenol, 9.70 mg/g for chlorophenol and 13.99 mg/g for o-cresol. In terms of removal percentage, after 15 h of experiment, the affinity order was as follows: phenol > chlorophenol > o-cresol > chromium(VI).Fundação para a Ciência e Tecnologia (FCT

First report of Hakea sericea leaf infection caused by Pestalotiopsis funerea in Portugal

[Excerpt] The woody shrub Hakea sericea (Proteaceae) is native of south-eastern Australia and has been considered as an invader of natural habitats. In northern Portugal, dense stands of this plant are rapidly spreading usually after intense forest fires (Fig. 1a). In May 2003, unusual leaf spots were observed on these naturally growing plants. Infected plants exhibit reddish leaves bearing black circular lesions with 1-3 mm in diameter (Fig. 1b,c). Leaf sections containing necrotic lesions were plated onto PDA (potato dextrose agar) and eight fungi isolates were obtained. Pure cultures exhibit pinkish mycelium bearing compact acervuli containing black and slimy spore masses (Fig. 2a). Microscopic observation revealed typical Pestalotiopsis sp. 5-celled spores (3 coloured median and 2 hyaline end cells) with 3-4 apical and 1 basal appendages (Fig. 2b,c). The identification of Pestalotiopsis at species level is difficult and has been based on morphological characteristics of conidia (Guba, 1961). Recently, molecular approaches have been reported based on sequencing the internal transcribed spacer region (ITS) of the ribosomal RNA operon and comparision of the sequenced region to its orthologs of already identified Pestalotiopsis species (Jeewon et al., 2002). In this work, genomic DNA from fungi isolates was purified using DNeasy ® Plant Mini Kit (Qiagen), and used as template in thermocyclic amplifications using Ready-To-GoTM PCR Beads (Amersham Biosciences) with ITS5 and ITS4 universal primers (White et al., 1990). The amplified sequences (599bp) were then analysed together with other Pestalotiopsis ITS sequences already edited in databases, using the programs ClustalX (alignment of sequences), GeneDoc (manual correction of the alignment) and Phylip (phylogenetic tree construction). The results showed that ITS sequences from all fungi isolates were identical to each other and 99.3% similar to Pestalotiopsis funerea (Fig. 3). To confirm the pathogenecity of Pestalotiopsis funerea towards Hakea sericea, 6 weeks-old plants grown in vitro were infected with a suspension containing 105 spores/ml and maintained at 22°C, under 16 h lightphotoperiod. After 6 days, in vitro plants exhibited tissue lesions identical to those observed in field plants, bearing fungus spores identical to those from original isolates.
