Poljoprivredna biomasa, zašto ne? [PDF]

EGE : energetika, gospodarstvo, ekologija, etika, 2020
Energetsko iskorištavanje biomase izravnim izgaranjem u posljednjih je nekoliko godina doživjelo ponovni uzlet. Najveća toplinska učinkovitost i najmanje emisije štetnih tvari postižu se pri tome izgaranjem peletirane biomase. Sve stroži ekološki zahtjevi Europske unije, osobito u pogledu emisija štetnih tvari, zahtijevaju kontinuirani razvoj novih ...

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Comprehensive framework for assessing and optimizing existing research networks

Conservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Adaptive Mesh Refinement Strategies for Cost-Effective Eddy-Resolving Transient Simulations of Spray Dryers

ChemEngineering, 2023
The use of adaptive meshing strategies to perform cost-effective transient simulations of spray drying processes is evaluated. These simulations are often computationally expensive, given the large differences between the characteristic times of the ...

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle

Journal of Zoology, EarlyView.
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...
