Spatial Variability in Recent Phototroph Production in a Large, Fluvial Lake Driven by Local Land‐Use Changes (St. Lawrence River, Canada)

Freshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT Increases in lake production and the abundance of cyanobacteria have been reported in many temperate freshwater systems, with their rise typically attributed to elevated nutrient influx or climate change. On the St. Lawrence River (SLR), recent evidence suggests that cyanobacterial abundances have increased since ca. 2000, although the precise

Substrates used in SIR assays can inhibit basal respiration in rewetted soil [PDF]

, 2010
Respiration assays are routinely used for investigating microbial metabolic activity in soil, but usually after a period of "conditioning" whereby dry soil is rewetted and incubated for a period of days.

Particle size distributions of radioactive pollution soils and its influence on consistence of the shelterbelt forest ranges

Forestry Engineering Journal, 2015
Presents characteristic of the soil texture that formed at mixture of moraine and fluvial-glacial deposits, moraine that overlaid clay loam mantle, clay loam mantle in shelterbelt forest ranges at south-west areas of the Bryansk region that contaminate radioactive fallouts in conse-quence of the Chernobyl accident. Dominant soil fractions determined in

Scaling Up of a Lightweight Aggregates System Based on Recovery Raw Materials and With Fertilisation Capacity: From Laboratory Prototype to Semi‐Industrial Production

Applied Research, Volume 5, Issue 4, August 2026.
Improved glass meltability enabled semi‐industrial prototyping of a residue‐derived PK fertiliser. Firing produced mechanically stable micropellets and induced partial vitrification, pore‐network reorganisation, delayed P release, but restricted K availability; 6‐month field trials on turfgrass and Photinia supported agronomic feasibility.

Spatially resolved 23Na magnetic resonance dispersion measurement in porous media

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 4135-4150, August 2026.
Quantitative 23Na MRI was employed to analyze dispersion in realistic core plug samples and was compared with the conventional breakthrough curve. 23Na MRI provided a more effective aassessment of core plug heterogeneity than the conventional method. Abstract Tracer tests are widely used in the petroleum industry to assess reservoir core plugs, relying

The status of natural radioactivity and heavy metals pollution on soil at Assiut Zone in Central Upper-Egypt

Radiation Protection and Environment, 2013
Context: To examine the status of the environmental quality of the soils in Assiut zone in central Upper-Egypt, investigation was carried out to determine the concentration of natural radionuclides (radium [ 226 Ra], thorium [ 232 Th] and 40 K) and the contents of eight heavy metals (Cd, Pb, Ni, Fe, Mn, Cr, Cu, and Zn).
