Assessing alkali activation of waste stone wool from greenhouses combined with direct foaming or granulation to obtain recycled plant substrate [version 1; peer review: 1 approved, 2 approved with reservations]

Open Research Europe
Background Stone wool is commonly used as a plant substrate in soilless cultivation and discarded after one growing season. Stone wool waste is difficult to recycle, and thus it is typically landfilled.

Diversity, Ecology and Biogeochemistry of Cyst-Forming Acantharia (Radiolaria) in the Oceans [PDF]

, 2013
Marine planktonic organisms that undertake active vertical migrations over their life cycle are important contributors to downward particle flux in the oceans.

Anthropic arguments outside of cosmology and string theory [PDF]

Belgrade Philosophical Annual, 2016
Anthropic reasoning has lately been strongly associated with the string theory landscape and some theories of particle cosmology, such as cosmological inflation. The association is not, contrary to multiple statements by physicists and philosophers alike,

A Hybrid Particle Swarm Optimisation-Genetic Algorithm for Multi-objective Reservoir Ecological Dispatching

Water Resources Management, 2022
Abstract Reservoir ecological dispatching is a complex system problem with multi-objective, multiple-criteria and multiple-phase. This study establishes a multi-objective ecological dispatching model in Changchun city of Yinma River Basin based on the water demand of social economic development, river ecology, and the constraint of reservoir ...

Isotopic constraints on the atmospheric sources and formation of nitrogenous species in clouds influenced by biomass burning [PDF]

Atmospheric Chemistry and Physics, 2019
Predicting tropospheric cloud formation and subsequent nutrient deposition relies on understanding the sources and processes affecting aerosol constituents of the atmosphere that are preserved in cloud water.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Developing environmental flow targets for benthic macroinvertebrates in large rivers using hydraulic habitat associations and taxa thresholds

Ecological Indicators, 2023
Holistic environmental flows frameworks are built on our understanding of key flow-ecology relationships that support sensitive taxa and critical ecosystem functions under different flow and water level scenarios.

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

Advanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

The Propagation of Sunlight and the Size Distribution of Suspended Particles in a Municipally Polluted Ocean Water [PDF]

, 1974
Waste discharge by the Los Angeles County Sanitation District (LACSD) affects sunlight in the ocean. Increased sunlight attenuance affects productivity and changes in ocean surface color could be useful for monitoring dispersal. Temperature, sunlight
