Long‐Term Storage of Meteoric Water in the Variscan Basement: Stable Isotope Constraints (δD–δ18O)

Terra Nova, Volume 38, Issue 2, Page 116-123, April 2026.
ABSTRACT F‐Ba‐Pb‐Zn (±Ag) deposits near the unconformity between the Armorican and Aquitaine basins formed by mixing surface waters and brines with fluid ascending from the basement. To better constrain the source of this fluid and the conditions of mixing, we analyzed the hydrogen (δDwater) and oxygen (δ18Owater) isotopic composition of water trapped ...

Pre‐Season Total Energy Expenditure and Dietary Intake of Professional Male Soccer Players: A Doubly Labelled Water Study

European Journal of Sport Science, Volume 26, Issue 3, March 2026.
ABSTRACT Limited data exist describing how professional footballers meet their energy requirements during pre‐season, a phase characterised by increased training volume and a progressive shift from general conditioning to football‐specific preparation.

Comportamento imunológico e antigênico de cinco amostras de Toxoplasma gondii inoculadas em gatos Immunogenic and antigenic aspects from five Toxoplasma gondii strains inoculated in cats

Ciência Rural, 1998
A biologia do Toxoplasma gondii demonstra que o gato é o hospedeiro completo, responsável pela disseminação do parasito. Assim, dois gatos domésticos foram imunizados com cada uma das amostras, VPS (humano), LIV-IV e LIV-V (suíno), CPL (caprino) e CN ...

Learning Surrogate Models of Document Image Quality Metrics for Automated Document Image Processing

, 2017
Computation of document image quality metrics often depends upon the availability of a ground truth image corresponding to the document. This limits the applicability of quality metrics in applications such as hyperparameter optimization of image ...

Early‐Life Respiratory Emissions of CO₂, CH₄, and N₂O in Pre‐Weaned Dairy‐Bred Calves

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Greenhouse gas (GHG) emissions from livestock are a major contributor to climate change, with cattle known to be the principal contributor through enteric fermentation, manure management, and metabolic processes. This study investigates the emission rates of CO₂, CH₄, and N₂O in pre‐weaned calves aged 12 to 86 days, focusing on the ...

A Temporally Consistent Spatial Gradient in Methane Ebullition From a Eutrophic Lake

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Gas bubble emission (ebullition) from lake sediment is a prominent source of the greenhouse gas methane (CH4) to the atmosphere, but the stochastic nature of bubble release and thus high variability in space and time makes the estimation of lake CH4 ebullition challenging.

Different fasting periods in tiletamine-zolezepam-anethetized cats: Glycemia, recovery, blood-gas and cardiorrespiratory parameters

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2013
The effects of different fasting periods on glycemia levels and on cardiorrespiratory parameters in tiletamine-zolazepam-anesthetized cats were evaluated. Twenty one animals were randomly assigned to three groups: 8 hours (G8), 12 hours (G12) or 18 hours

AutoChamber: A broadly accessible 3D‐printed floating chamber to automate measurements of greenhouse gas emissions from surface waters

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 979-991, March 2026.
Abstract Fresh waters provide environmental conditions that favour microbial CO2 and CH4 production, leading to the release of large quantities of greenhouse gases (GHG) to the atmosphere. Despite their importance, these fluxes remain poorly defined, weakening estimates of global GHG budgets that are critical in implementing effective climate ...
