Trace elemental composition of curry by inductively coupled plasma optical emission spectrometry (ICP-OES)

2008

A methodology based on inductively coupled plasma optical emission spectrometry (ICP-OES) after microwave-assisted acid digestion was developed to determine the content of traces elements in curry samples from the Spanish market. The methodology was validated in terms of accuracy by the analysis of citrus and tomato leaf reference materials achieving comparable results with the certified values. The trace metal content of curry samples was compared with data available from previously published reports concerning Indian samples, especially in terms of heavy metal composition, in order to guarantee the quality of the commercially available spices in the European countries. Values found for th…

Optimization of operating conditions of axially and radially viewed plasmas for the determination of trace element concentrations from ultrasound-ass…

2006

Abstract The method of ultrasound-assisted extraction followed by inductively coupled plasma optical emission spectrometry (ICP-OES) used for the determination of trace element concentrations (arsenic, copper, lead, antimony, and zinc) in shooting range areas was optimized. Optimization was achieved not only on the basis of the analysis of appropriate standard reference materials but also on that of 31 synthetic mixtures of matrix and analyte elements (aluminum, antimony, arsenic, calcium, copper, lead, iron, manganese, silicon, and zinc), in five concentrations. All the measurements were performed in robust plasma conditions which were tested by measuring the Mg II 280.270 nm/Mg I 285.213 …

Diversity of ankA and msp4 genes of Anaplasma phagocytophilum in Slovenia.

2015

Granulocytic anaplasmosis is a tick transmitted emerging disease in Europe and worldwide. The agent, Anaplasma phagocytophilum is transmitted by ticks of the genus Ixodes and causes infections in humans and domestic animals. The analysis of different target genes showed that in nature several genetic variants of A. phagocytophilum were present. The purpose of our study was to genetically characterize A. phagocytophilum strains from eight humans, 16 dogs, 12 wild boars, one bear and 18 tick pools from Slovenia. Therefore, the ankA and msp4 genes of A. phagocytophilum were chosen. The same genetic ankA and msp4 variant of A. phagocytophilum was detected in humans, wild boar and a part of the …

Study of surface layers and ejected powder formed by oxidation of titanium substrates with a pulsed Nd:YAG laser beam.

2009

Laser treatment of a titanium surface at certain conditions initiates the formation of titanium oxide layers as well as micro (nano) scale powder ejected from the surface of the substrate. The resultant morphology of the surface as well as the size and the structure of the particles are all strongly dependent on the treatment parameters (laser fluence, pulse frequency, overlap parameter, etc.). In this study, titanium substrates were treated with an industrial pulsed Nd:YAG laser in air, with varying parameters. Surface layers and ejected materials were compared using scanning and transmission electron microscopy, X-ray diffraction and Raman spectroscopy. The rutile phase of TiO(2) dominate…

Polar bosons in one-dimensional disordered optical lattices

2013

We analyze the effects of disorder and quasi-disorder on the ground-state properties of ultra-cold polar bosons in optical lattices. We show that the interplay between disorder and inter-site interactions leads to rich phase diagrams. A uniform disorder leads to a Haldane-insulator phase with finite parity order, whereas the density-wave phase becomes a Bose-glass at very weak disorder. For quasi-disorder, the Haldane insulator connects with a gapped generalized incommesurate density wave without an intermediate critical region.

Intraoperative cell salvage in ruptured abdominal aortic aneurysms

2010

Aim. The aim of this study was to evaluate the impact of intraoperative cell salvage (ICS) on the early outcome after open repair (OR) of ruptured abdominal aortic aneurysm (rAAA). Methods. This is a retrospective review of 73 consecutive patients who underwent emergency OR of infrarenal rAAA with ICS between 2005 and 2008 (Group I), compared to 51 repairs from 2002-2004 with no ICS (Group II). In addition, a transfusion protocol of platelets and fresh frozen plasma (FFP) administration on admission and during surgery was adopted in patients in Group I to maintain coagulation competence. Results. ICS reduced bank blood demand by 63.6% (from 11 to 4 units, P<0.001) compared to controls, and …

Ultracold Rare-Earth Magnetic Atoms with an Electric Dipole Moment

2018

We propose a new method to produce an electric and magnetic dipolar gas of ultracold dysprosium atoms. The pair of nearly degenerate energy levels of opposite parity, at 17513.33 cm$^{-1}$ with electronic angular momentum $J=10$, and at 17514.50 cm$^{-1}$ with $J=9$, can be mixed with an external electric field, thus inducing an electric dipole moment in the laboratory frame. For field amplitudes relevant to current-day experiments, we predict a magnetic dipole moment up to 13 Bohr magnetons, and an electric dipole moment up to 0.22 Debye, which is similar to the values obtained for alkali-metal diatomics. When a magnetic field is present, we show that the electric dipole moment is strongly…

Probing mechanical quantum coherence with an ultracold-atom meter

2011

We propose a scheme to probe quantum coherence in the state of a nano-cantilever based on its magnetic coupling (mediated by a magnetic tip) with a spinor Bose Einstein condensate (BEC). By mapping the BEC into a rotor, its coupling with the cantilever results in a gyroscopic motion whose properties depend on the state of the cantilever: the dynamics of one of the components of the rotor angular momentum turns out to be strictly related to the presence of quantum coherence in the state of the cantilever. We also suggest a detection scheme relying on Faraday rotation, which produces only a very small back-action on the BEC and it is thus suitable for a continuous detection of the cantilever'…
