El coeficiente de descarga y la densidad beta

open access: yesTecnología y ciencias del agua, 2014
Se estudia el coeficiente de descarga y la distribución de intensidades de la turbulencia. Con el teorema de Torricelli y la teoría de probabilidades se formulan el caudal y el coeficiente de descarga, siguiendo una densidad beta unimodal, renormalizada,

Gross Agricultural Emissions and Unequal Mitigation Pathways in the Brazilian Legal Amazon: Implications for Climate Justice and the Sustainable Development Goals

open access: yesSustainable Development, EarlyView.
ABSTRACT Climate mitigation policies in the Brazilian Legal Amazon have largely focused on aggregate or net emissions, providing limited evidence on how gross agricultural emissions reveal the intensity of productive emission sources independently of carbon removals.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

The PhenoChange network protocol for monitoring leaf phenology in tropical dry ecosystems using phenocameras

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Tropical dry ecosystems (TDEs) cover half of the tropics and play a key role in global carbon dynamics. TDEs present distinct canopy and ground layers that often exhibit contrasting phenological patterns. On‐the‐ground observations of phenology by the human eye, though valuable, may suffer from limited temporal resolution and observer biases ...

Enhanced fish detection sensitivity in aquatic systems using environmental RNA

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Environmental RNA (eRNA) can potentially augment the biological monitoring ability of the established environmental DNA (eDNA) application in conservation. Despite faster degradation, environmental RNA could offer unique advantages: it may help reduce the legacy signal compared to eDNA, provide insights into physiological status through gene ...

16S/18S metabarcoding versus culture for aetiological assessment in infectious keratitis: A prospective paired‐sample study

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Infectious keratitis (IK) is a vision‐threatening condition with diverse microbial aetiologies, yet conventional culture‐based diagnostics often have limited sensitivity. We investigated whether 16S/18S rRNA amplicon‐based next‐generation sequencing (NGS) can enhance aetiological assessment when used alongside standard microbiological ...

Clinical Course and Predictors of Biologic Therapy, Hospitalisation and Surgery: A Five‐Year Prospective Study in Newly Diagnosed Inflammatory Bowel Disease

open access: yesAlimentary Pharmacology &Therapeutics, EarlyView.
In this large multicentre Spanish inception cohort, biologics/JAK inhibitors were frequently used during the first 5 years after inflammatory bowel disease diagnosis and were associated with reduced hospitalisation risk, although not with lower abdominal surgery rates.
