Using the capabilities approach to achieve people‐centered conservation

open access: yesConservation Biology, EarlyView.
Abstract Top‐down interventions carried out by state and nonstate institutions to conserve biodiversity and improve the lives of forest‐proximate people (FPP) in the Global South tend to reflect economistic understandings of human well‐being. More progressive and people‐centered conservation projects are guided by normative visions of how the world ...

Plant Growth and Arthropod Assemblage Metrics on Sapindus saponaria Fertilized With Dehydrated Municipal Sewage Sludge

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Under the conditions evaluated, dehydrated municipal sewage sludge increased branches per plant and ground cover in Sapindus saponaria and increased cumulative arthropod observations and species richness in selected groups. Exploratory multivariate patterns did not demonstrate direct causal plant–arthropod relationships.

Influence of carbonate apatite nanoparticles incorporated into commercial dental adhesives on immediate and long‐term microtensile bond strength

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This study assessed whether integrating carbonate apatite nanoparticles with a CO3/PO4 molar ratio of 5 (CA5n) into commercial adhesives affected the immediate or the long‐term microtensile bond strength (µTBS) between composite resin and dentin.

Mitochondrial iron homeostasis is required for azole tolerance in Candida albicans

open access: yesThe FEBS Journal, EarlyView.
In Candida albicans, the deletion of MRS4, which encodes a mitochondrial iron importer, abolishes fluconazole tolerance and increases cidality during cotreatment with the iron chelator BPS, without altering MIC or synergy. Fluconazole‐treated mutants exhibit increased mitochondrial depolarisation, fragmentation and reduced mitochondrial density.

Quantification of Sulfur Speciation in Apatites: Comparison of the XAS, XPS and EPMA Techniques

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Sulfur speciation in apatites has been determined by S K‐edge X‐ray absorption near‐edge structure (XANES) spectroscopy, S 2p X‐ray photoelectron spectroscopy (XPS) and electron probe microanalysis (EPMA). XANES provides the most sensitive and accurate quantification of sulfur speciation.

Índice de reactividad intrínseco de carbones concentrados ricos en vitrinita

open access: yesIngeniería e Investigación, 2007
En este trabajo se definió un nuevo parámetro de reactividad de carbón a la combustión llamado índice de reactividad intrínseco (IRI), el cual combina la fracción maceral reactiva (vitrinita/liptinita), la fracción maceral no reactiva (inertinita/materia
