Spatio-temporal nested patterns in macroinvertebrate assemblages across a pond network with a wide hydroperiod range
(Springer Nature, 2011)
Nestedness has been widely used to measure the structure of biological communities and occurs when species-poor sites contain subsets of species-rich ones. Here, we examine nested patterns across the macroinvertebrate ...

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 ...

Designing robust rapid transit networks with alternative routes
(Hindawi, 2011-01)
The aim of this paper is to propose a model for the design of a robust rapid transit network. In this paper, a network is said to be robust when the effect of disruption on total trip coverage is minimized. The proposed model ...

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 ...

Use of Urea and Ammonia to Produce High-Strength PM Aluminium Parts
(European Powder Metallurgy Association (EPMA), 2011)
Two methods to obtain bulk nanostructured aluminium parts are compared. The first one consists on milling Al powder in an ammonia gas atmosphere. In the second method, the Al powder is milled in vacuum with the addition ...
