The importance of Silver fir (Abies alba Mill.) in comparison to spruce (Picea abies (L.) Karst.) and oak (Quercus petraea (Matt.) Liebl.) for arboreal Heteroptera communities in Bavarian forests [PDF]

, 2005
Heteropteran communities in the canopies of Silver fir (Abies alba) and spruce (Picea abies) were studied at three lowland and three mountainous sites throughout Bavaria using flight-interception traps.

Tailoring the Melting and Glass Transition Behavior of Zeolitic Imidazolate Frameworks via Ammonium Halide Salts

Small, EarlyView.
Ammonium halide salts serve as inorganic modifiers that lower the melting and glass transition temperatures of zeolitic imidazolate frameworks, enabling centimeter‐scale hybrid glasses and melt processing of otherwise unmeltable ZIF‐8. In situ imaging and pair distribution function analysis reveal salt infiltration, Zn─N bond disruption, and Zn–halide ...

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction

steel research international, EarlyView.
Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in

Monte Carlo Predictions of Far-Infrared Emission from Spiral Galaxies [PDF]

, 2000
We present simulations of Far Infrared (FIR) emission by dust in spiral galaxies, based on the Monte Carlo radiative transfer code of Bianchi, Ferrara & Giovanardi (1996).

Incremental upper bound modeling of concrete failures in timber‐concrete notched connections

Structural Concrete, EarlyView.
Abstract This paper introduces a novel theoretical framework for developing incremental upper bound solutions, which is applied to predict the response of two local concrete failures in timber‐concrete composite (TCC) decks with notched connections. The new approach enables a prediction of the capacity at the onset of failure as well as the entire post‐

Nature‐Positive Materials Engineering: Carbon Electrodes from Satoyama Biomass

The Chemical Record, EarlyView.
Nature‐positive materials engineering can link satoyama forest stewardship with the design of carbon electrodes for batteries, supercapacitors, and electrocatalysis. By turning underused firewood and charcoal resources into functional carbons, this approach reduces mining footprints while supporting biodiversity, landscape resilience, and regional ...

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

A high‐altitude thermal infrared method for estimating moose abundance and demography in Rocky Mountain National Park, USA

Wildlife Biology, EarlyView.
Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Spatial distribution of far infrared emission in spiral galaxies I. Relation with radio continuum emission

, 1997
We use high resolution IRAS and 20 cm radio continuum (RC) images of a sample of 22 spiral galaxies to study the correlation between the far infra-red (FIR) and RC emissions within the galactic disks.
