Thermoplastic polyurethanes with glycolysate intermediates from polyurethane waste recycling.
(Elsevier, 2017-10)
The polyol is a major component in polyurethane formulations and therefore introducing to the formulation recycled polyol (obtained during decomposition process) allows decreasing the usage of pure petrochemical components. ...
Optimizing the extraction process of natural antioxidants from chardonnay grape marc using microwave-assisted extraction
(2019-03-21)
The aim of this work was to extract phenolic compounds from Chardonnay grape marc employing a
microwave-assisted extraction (MAE). Firstly, the effect of solvent concentration (30–60%), solid mass
(1.0–2.0 g) and extraction ...
Time Trends in Serum Organochlorine Pesticides and Polychlorinated Biphenyls in the General Population of Biscay, Spain
(Springer, 2015-01)
Despite the measures adopted, levels of organochlorine compounds (OCs) are still being detected in the human body. This study aimed to explore factors related to changes in the concentrations of polychlorinated biphenyls ...
The Clinical Profile Of Adolescent Offenders Of Child-To-Parent Violence
(Elsevier, 2014-06-02)
[EN]The aim of the present study was to examine whether juvenile offenders with charges for parent abuse had a different clinical profile from that of juveniles with charges for other offences and from that of non-offenders. ...
Thermal treatments and transformation behavior of Cu–Al–Be shape memory alloys
(Elsevier, 2013-11-15)
Among the different Cu-based shape memory alloys, the Cu–Al–Be family exhibits a particular technological interest for intermediate and low temperature applications. In this work we studied the martensitic transformation ...
Plant Responses to Extreme Climatic Events: A Field Test of Resilience Capacity at the Southern Range Edge.
(Public Library Science, 2014-01-28)
The expected and already observed increment in frequency of extreme climatic events may result in severe vegetation shifts. However, stabilizing mechanisms promoting community resilience can buffer the lasting impact of ...
Peripheral immune system and neuroimmune communication impairment in a mouse model of Alzheimer´s disease
(2012-07-23)
eurodegenerative diseases such as Alzheimer's disease (AD) can be understood in the context of the aging of neuroimmune communication. Although the contribution to AD of the immune cells present in the brain is accepted, ...
Positive associations among rare species and their persistence in ecological assemblages
(Springer Nature, 2019-12-16)
According to the competitive exclusion principle, species with low competitive abilities should be excluded by more efficient competitors; yet, they generally remain as rare species. Here, we describe the positive and ...
Prediction of Two-dimensional Phase of Boron with Anisotropic Electric Conductivity
(2017-03-01)
Two-dimensional (2D) phases of boron are rare and unique. Here we report a new 2D all-boron phase (named the π phase) that can be grown on a W(110) surface. The π phase, composed of four-membered rings and six-membered ...
Prevalence and clonal characterization of Streptococcus pyogenes clinical isolates with reduced fluoroquinolone susceptibility in Spain
(2010-01-01)
The aim of this study was to determine the prevalence and characteristics of non-fluoroquinolone (FQ)-
susceptible Streptococcus pyogenes isolates and to study their mechanisms of resistance. We performed a prospective ...
