HIV-1 subtype distribution and its demographic determinants in newly diagnosed patients in Europe suggest highly compartmentalized epidemics
(2013)
Background: Understanding HIV-1 subtype distribution and epidemiology can assist preventive measures and clinical decisions. Sequence variation may affect antiviral drug resistance development, disease progression, ...
Structural and Redox Properties of Ce1-xZrxO2-δ and Ce0.8Zr0.15RE0.05O2-δ (RE: La, Nd, Pr, Y) Solids Studied by High Temperature in Situ Raman Spectroscopy
(2017)
In situ Raman spectroscopy at temperatures up to 450 °C is used to probe the structural and redox properties of Ce1-xZrxO2-δ solids (x = 0-0.8) prepared by the citrate sol-gel and coprecipitation with urea methods. The ...
Simulation models for evaluation of terminal operations and traffic flow on adjacent road network
(2009)
The goods movement via terminals at ports is a complex operation as it involves use of different modes of transport that includes surface and marine. In this paper, we present three simulation models which can be used to ...
Dynamic adaptive data structures for monitoring data streams
(2008)
The monitoring of data streams is a very important issue in many different areas. Aspects such as accuracy, the speed of response, the use of memory and the adaptability to the changing nature of data may vary in importance ...
A simplified determination of uranium in phosphate rock and phosphogypsum by alpha-spectroscopy after its separation by liquid-extraction
(2012)
A relatively rapid, economic and robust procedure is described for the radiometric analysis of uranium in phosphate rock and phosphogypsum. The analysis is performed by alpha spectroscopy after pre-concentration and ...
Dynamic count filters
(2006)
Bloom filters are not able to handle deletes and inserts on multisets over time. This is important in many situations when streamed data evolve rapidly and change patterns frequently. Counting Bloom Filters (CBF) have been ...
The effect of natural organic matter on the formation and solubility of M(OH)4 solid phases
(2014)
In this study the formation of M(OH)4 solid phases (e.g. Th(IV), Ce(IV) and Zr(IV)) has been investigated as a function of the natural organic matter (NOM) concentration in 0.1 M NaClO4, in the pH range between 2 and 5, ...
The effect of humic acid on the formation and solubility of secondary solid phases (Nd(OH)CO3 and Sm(OH)CO3)
(2011)
The formation of secondary Ln(III) solid phases (e.g. Nd(OH)CO3 and Sm(OH)CO3) has been studied as a function of the humic acid (HA) concentration in 0.1M NaClO4 aqueous solution and their solubility has been investigated ...
Alpha radiometry of uranium in surface and ground waters by liquid scintillation counting after separation of the radionuclide by cation exchange
(2008)
The alpha radioactivity of surface and ground water samples has been determined by liquid scintillation counting (LSC) after chemical preparation of the samples by cation exchange using the Chelex 100 resin. The method ...
Spectroscopic investigations on the effect of humic acid on the formation and solubility of secondary solid phases of Ln2(CO3) 3
(2011)
The formation of secondary Ln(III) solid phases (e.g., Nd 2(CO3)3 and Sm2(CO3) 3) was studied as a function of the humic acid concentration in 0.1 mol/L NaClO4 aqueous solution in the neutral pH range (5-6.5). The solid ...
