Kinetics of the acid-catalyzed hydrolysis of tetraethoxysilane (TEOS) by 29Si NMR spectroscopy and mathematical modeling
Tetraethoxysilane (TEOS) is widely used to synthesize siliceous material by the sol–gel process. However, there is still some disagreement about the nature of the limiting step in the hydrolysis and condensation reactions. ... -

Artikulu honek langile bizitzaren aspektu horietariko bat izango du ardatz: auzoaren esparrua. Britainiar langile klasearen osaera prozesuari heltzeko E.P Thompson historialariak jorratutako ikuspegian klase esperientzia ... -
Klebsiella pneumoniae outer membrane protein A is required to prevent the activation of airway epithelial cells
Outer membrane protein A (OmpA) is a class of proteins highly conserved among the Enterobacteriaceae family and throughout evolution. Klebsiella pneumoniae is a capsulated Gram-negative pathogen. It is an important cause ... -
Knots untie: molecular determinants involved in knot formation Induced by Pseudomonas savastanoi in woody hosts
The study of the molecular basis of tree diseases is lately receiving a renewed attention, especially with the emerging perception that pathogens require specific pathogenicity and virulence factors to successfully colonize ... -
Knowledge drivers, business collaboration and competitiveness in rural and urban regions
Many rural regions are characterised by low technology-intensive activities. Their predominant focus is often on primary, agri-food, and natural resources and services sectors, and there is a competitive gap with respect ... -
Knowledge extraction from L-fuzzy contexts associated with criteria evolving over time
Information extracted from L-fuzzy contexts is substantially improved by taking into account different points of view, which can roughly be represented by criteria. This work addresses the general study of L-fuzzy contexts ... -
Knowledge models as meaningful and long life learning alternative for rare disease affected students
Rare diseases (RDs) are considered all diseases affecting to less than or equal to 5 in 10.000 citizens, criteria followed by most European Countries. Since most RDs incur disabling conditions, a few patients seldom reach ... -
Knowledge models on biosphere reserves for visual and sustainable meaningful learning in pre-service teachers: quo vadis, visual pedagogies?
It is undeniable that climate change has become one of the greatest global challenges facing humanity in the coming decades. Since the Earth Summit held in Rio de Janeiro in 1992, all climate summits have emphasized the ... -
The Krypteia ensemble: designing classifier ensembles using an ancient Spartan military tradition
In this work we propose a new algorithm to train and optimize an ensemble of classifiers. We call this algorithm the Krypteia ensemble, based on an ancient Spartan tradition designed to convert their most promising individuals ... -
Ku band low profile asymmetric Bull’s-Eye antenna with reduced side lobes and monopole feeding
In this paper, a linearly polarized low profile and asymmetric Bull’s-Eye leaky wave antenna fed by a monopole operating at 13 GHz is presented. Broadside radiation from the monopole is achieved by surrounding it with an ... -
L-band multiwavelength single-longitudinal mode fiber laser for sensing applications
In this work, a novel single-longitudinal-mode (SLM) four-wavelength laser configuration for sensing applications in the L-band is proposed and experimentally demonstrated. The sensor system presented here is based on ring ... -
Label-free wavelength and phase detection based SMS fiber immunosensors optimized with cladding etching
The performance of E-SMS (Etched Singlemode-Multimode-Singlemode) optical fiber structures as immunosensors has been assessed by the implementation of antibody/antigen immunoassays. Through this procedure it has been ... -

Se conceptualiza este trastorno como una adicción psicológica y se exponen los aspectos psicopatológicos que lo ... -
Labyrinth metasurface absorber for ultra-high-sensitivity terahertz thin film sensing
In this work, a labyrinth metasurface sensor operating at the low‐frequency edge of the THz band is presented. Its intricate shape leads to a high electric field confinement on the surface of the structure, resulting in ... -
Labyrinth metasurface for biosensing applications: numerical study on the new paradigm of metageometries
The use of metasurfaces operating in the terahertz regime as biosensor devices has attracted increased interest in recent years due to their enhanced sensitivity and more accurate detection capability. Typical designs are ... -
Lacanobia oleracea nucleopolyhedrovirus (LaolNPV): a new European species of alphabaculovirus with a narrow host range
During an insect sampling program in alfalfa crops near Montpellier, France in 2011, Lacanobia oleracea larvae were collected that died due to nucleopolyhedrovirus infection (LaolNPV). This virus was subjected to molecular ... -
Lack of relationship between Visna/maedi infection and scrapie resistance genetic markers
(Instituto Nacional de Investigacion y Tecnologia Agraria y Alimentaria (INIA), 2014) Artículo / ArtikuluaThe relationship between Visna/maedi virus (VMV) antibody status and scrapie genetic resistance of 10,611 Rasa Aragonesa sheep from 17 flocks in Aragón (Spain) was investigated. The fifteen most common PRNP gene haplotypes and ... -
Lack of the PGA exopolysaccharide in Salmonella as an adaptive trait for survival in the host
Many bacteria build biofilm matrices using a conserved exopolysaccharide named PGA or PNAG (poly-β-1,6-N-acetyl-D-glucosamine). Interestingly, while E. coli and other members of the family Enterobacteriaceae encode the ... -
