Direct magnetocaloric measurements of Fe-B-Cr-X (X = La, Ce) amorphous ribbons
(American Institute of Physics, 2011)
A procedure has been developed to directly measure the adiabatic temperature change of amorphous melt-spun Fe-based ribbons displaying attractive room temperature magnetocaloric properties. Polycrystalline Gd ribbons are ...

Matrix Representation of Spiking Neural P Systems
(Springer, 2011)
Spiking neural P systems (SN P systems, for short) are a class of distributed parallel computing devices inspired from the way neurons communicate by means of spikes. In this work, a discrete structure representation of ...

Immunohistochemical assessment of Pax8 expression during pancreatic islet development and in human neuroendocrine tumors
(Springer Verlag, 2011)
The paired box transcription factor Pax8 is critical for development of the eye, thyroid gland as well as the urinary and reproductive organs. In adult, Pax8 overexpression is associated with kidney, ovarian and thyroid ...

A Tool for Web Links Prototyping
(CSREA Press, 2011)
Crawlers for Virtual Integration processes must be efficient, given that VI process is online, which means that while the system is looking for the required information, the user is waiting for a response. Therefore, ...

Computation of Ramsey Numbers by P Systems with Active Membranes
(World Scientific, 2011)
Ramsey numbers deal with conditions when a combinatorial object necessarily contains some smaller given objects. It is well known that it is very difficult to obtain the values of Ramsey numbers. In this work, a theoretical ...

On using high-level structured queries for integrating deep-web information sources
(2011)
The actual value of the Deep Web comes from integrating the data its applications provide. Such applications offer human-oriented search forms as their entry points, and there exists a number of tools that are used to fill ...

Yeast Sen1 helicase protects the genome from transcription-associated instability
(Elsevier, 2011-01-06)
Sen1 of S. cerevisiae is a known component of the NRD complex implicated in transcription termination of nonpolyadenylated as well as some polyadenylated RNA polymerase II transcripts. We now show that Sen1 helicase possesses ...

Comparative study of the photodeposition of Pt, Au and Pd on pre-sulphated TiO2 for the photocatalytic decomposition of phenol
(Elsevier, 2011)
A comparative study of the photodeposition of Pt, Au and Pd under the same experimental conditions onto pre-sulphated and non-sulphated TiO2 was performed. Morphological and surface characterisation of the samples as well ...

Angular emission properties of a layer of rare-earth based nanophosphors embedded in one-dimensional photonic crystal coatings
(American Institute of Physics, 2011)
The angular properties of light emitted from rare-earth based nanophosphors embedded in optical resonators built in one-dimensional photonic crystal coatings are herein investigated. Strong directional dependence of the ...
