451. Start-up phase of an anaerobic full-scale farm reactor - Appearance of mesophilic anaerobic conditions and establishment of the methanogenic microbial community
Date: 21-04-16 

The goal of this study was to investigate how the microbial community structure establishes during the start-up phase of a full-scale farm anaerobic reactor inoculated with stale and cold cattle

452. Identification of building double-bounces feature in very high resoultion SAR data for earthquake damage mapping
Date: 14-04-16 

Nowadays very high resolution (VHR) Synthetic Aperture Radar (SAR) systems can provide near real time earthquake damage maps with an high degree of details to stakeholders in charge of managing the

453. Multi-scale and spatially resolved hydrogen mapping in a Ni-Nb model alloy reveals the role of the δ phase in hydrogen embrittlement of alloy 718
Date: 09-03-16 

We investigated the hydrogen distribution and desorption behavior in an electrochemically hydrogen-charged binary Ni–Nb model alloy to study the role of δ phase in hydrogen embrittlement of alloy

454. Chemistry of surface nanostructures in lead precursor-rich PbZr0.52Ti0.48O3 sol-gel films
Date: 02-03-16 

We present a study of the chemistry of the nanostructured phase at the surface of lead zirconium titanate PbZr0.52Ti0.48O3 (PZT) films synthesized by sol–gel method. In sol–gel synthesis, excess lead

455. Chemical stability and bioaccessibility of ß-carotene encapsulated in sodium alginate o/w emulsions: Impact of Ca2+ mediated gelation
Date: 02-03-16 

In the present work, 5% (w/w) canola oil-in-water submicron emulsions containing sodium alginate were investigated as β-carotene (0.05% w/w) carriers. O/w emulsions prepared via spontaneous

456. Training model trees on data streams with missing values
Date: 23-02-16 

Model trees combine the interpretability of decision trees with the efficiency of multiple linear regressions making them useful in dynamically attaining predictive analysis on data streams. However,

457. An advanced numerical model for energy conversion and crack growth predictions in Solid Oxide Fuel Cell units
Date: 18-02-16 

A dynamic mathematical model capable of predicting the energy conversion and crack propagation in Solid Oxide Fuel Cell (SOFC) unit is developed. Finite Element Method (FEM) and eXtended Finite

458. Orientation-dependence of thermal depolarization and phase development in Bi1/2Na1/2TiO3-BaTiO3 single crystals
Date: 18-02-16 

The direction-dependence of pyroelectric properties of (1 − x)Bi1/2Na1/2TiO3 − xBaTiO3 (BNT − 100xBT) is investigated, using single crystal samples with well-defined orientations for x = 0.036 and x

459. Flexoelectricity, incommensurate phases and the Lifshitz point
Date: 16-02-16 

The solutions for the minimizers of the energy density f (q, p)  =  Aq2 + Bq4 + p2 + gA,B + β(q'p - p'q)+|q'|2+K|p'|2 describe the flexoelectric effect with a flexoelectric coupling coefficient β.

460. Arbres de modèles et flux de données incomplets
Date: 25-01-16 

Model tree is a useful and convenient method for predictive analytics in data streams.Often, this issue is solved by pre-processing techniques applied prior to the training phase of the model. In
