Influence of the concentration of copper nanoparticles on the thermo-mechanical and antibacterial properties of nanocomposites based on poly(butylene adipate-co-terephthalate)
(WILEY, 2019)
Poly(butylene adipate-co-terephthalate) (PBAT) was mixed with copper nanoparticles (Cu-NPs) in concentrations of 1%, 3%, and 5% with particle size between 100 nm and 200 nm by the melting method. A morphological, thermal, ...
Physical reasoning to synchronize electrical signals and related diagnostics in plasma focus devices
(Chile. Universidad Mayor, 2018-02)
Plasma Focus (PF) devices as well as other similar pulsed discharge devices requires a variety of diagnostics for their proper control and optimization, including the voltage between electrodes, the time derivative of the ...
Initial response of understorey vegetation and tree regeneration to a mixed-severity fire in old-growth Araucaria-Nothofagus forests
(WILEY, 2019)
Questions Fire is a key factor influencing Araucaria araucana forests, but the impact of fire severity on the understorey vegetation is not well understood. In this study we seek to answer the following questions: (a) how ...
Synthesis and characterization of processable fluorinated aromatic poly (benzamide imide)s derived from cycloalkane substituted diamines, and their application in a computationally driven synthesis methodology
(ELSEVIER SCI LTD, 2019)
A new set of four fluorinated aromatic poly(benzamide imide)s was synthesized with the objective of preparing condensation polymers with good processability while maintaining high chemical resistance, thermal stability and ...
Caracterización de los patrones de actividad física en distintos grupos etarios chilenos
(ARAN EDICIONES, S L, 2019)
Background: international physical activity (PA) guidelines recommend 150 minutes of moderate to vigorous PA or 75 minutes of vigorous PA weekly; however, the proportion of the Chilean population who meet this recommendation ...
Implications of climate change for semi-arid dualistic agriculture: a case study in Central Chile
(SPRINGER HEIDELBERG, 2019)
The nexus between climate change, agriculture, and poverty has become a major topic of concern, especially for dry regions, which represent a large share of the world's population and ecosystems vulnerable to climate change. ...
Comparison of different land degradation indicators: Do the world regions really matter?
(WILEY, 2019)
In 2010, the Convention on Biological Diversity created the Aichi Biodiversity targets to aid the restoration of degraded ecosystems, which include the restoration of at least 15% of degraded ecosystems by 2020. A crucial ...
Sodium tungstate: Is it a safe option for a chronic disease setting, such as diabetes?
(WILEY, 2019)
Diabetes is a complex metabolic disorder triggered by the deficient secretion of insulin by pancreatic cells, the resistance of peripheral tissues to the action of the hormone, or both, and is characterized by chronic ...
Association of high 5-hydroxymethylcytosine levels with Ten Eleven Translocation 2 overexpression and inflammation in Sjogren's syndrome patients
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2018)
Here, we determined the 5-hydroxymethylcytosine (5hmC), 5-methylcytosine (5mC), Ten Eleven Translocation (TETs), and DNA methyltransferases (DNMTs) levels in epithelial and inflammatory cells of labial salivary glands (LSG) ...
Arsenic removal mediated by acidic pH neutralization and iron precipitation in microbial fuel cells
(ELSEVIER SCIENCE BV, 2018)
High concentrations of arsenic (As) in natural waters are a growing concern worldwide. In northern Chile, fluvial systems enriched in As from natural and anthropogenic sources have been found to contain microbial communities ...
