Short-term nitrous oxide emissions from pasture soil as influenced by urea level and soil nitrate [PDF]

, 2004
Nitrogen excreted by cattle during grazing is a significant source of atmospheric nitrous oxide (N2O). The regulation of N2O emissions is not well understood, but may vary with urine composition and soil conditions.

Determination of THC and THC‐COOH in Dried Capillary Blood Spots and Comparison to Venous Blood of Recreational Cannabis Consumers in a Pilot Study

Drug Testing and Analysis, EarlyView.
A new extraction method was developed and validated for the extraction of THC and THC‐COOH from capillary blood samples collected as dried blood spots. The extracts were analysed using HPLC–MS/MS resulting in high extraction efficiencies for both THC and THC‐COOH.

Long‐term cardiovascular outcomes of immune checkpoint inhibitor‐related myocarditis: A large single‐centre analysis

ESC Heart Failure, Volume 12, Issue 2, Page 1237-1245, April 2025.
Abstract Aims Immune checkpoint inhibitors (ICI) are the cornerstone of modern oncology; however, side effects such as ICI‐related myocarditis (irM) can be fatal. Recently, Bonaca proposed criteria for irM; however, it is unknown if they correlate well with cardiovascular (CV) ICI‐related adverse events.

Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

Fire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...

A J-function for inhomogeneous spatio-temporal point processes [PDF]

, 2013
We propose a new summary statistic for inhomogeneous intensity-reweighted moment stationary spatio-temporal point processes. The statistic is defined through the n-point correlation functions of the point process and it generalises the J-function when ...

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

Journal of Applied Toxicology, EarlyView.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

Effects of Biochar and Maize Roots on CO2 Emissions and Microbial Biomass C in Loess Soils

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Refractory substances such as biochar and labile substances such as dead fine and coarse roots play important roles in soil organic matter dynamics and have key ecological functions. However, interactions between these substances have only rarely been studied.

Metabolic kinetics of pulmonary surfactant in newborn infants using endogenous stable isotope techniques

Journal of Lipid Research, 2005
We compared kinetic indices of pulmonary surfactant metabolism in premature infants (n = 41) with respect to i) tracer ([1-13C1]acetate, [U-13C6]glucose, and [1,2,3,4-13C4] palmitate), ii) phospholipid (PL) pool (total PLs or disaturated PLs), or iii ...
