Assessment of the Interaction between Ammonium Dinitramide and Isocyanurate Bonding Agents for Application on Technologies of Composite Solid Propellants

Propellants, Explosives, Pyrotechnics, EarlyView.
This work investigates the interaction of two isocyanurate‐based bonding agents with ammonium dinitramide: triallyl isocyanurate and 1,3,5‐tris(2‐hydroxyethyl) isocyanurate, which contain alkene and hydroxyl functional groups in their side chains, respectively.

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

Environmental Toxicology, EarlyView.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.

Long‐term trends of epibionts reflect Mediterranean striped dolphin abundance shifts caused by morbillivirus epidemics

Journal of Animal Ecology, EarlyView.
This original research piece demonstrates, through empirical and theoretical modelling approaches, that the epibionts of striped dolphins indicate dolphin abundance shifts caused by epidemics of dolphin morbillivirus (DMV). In addition, we provide the first SIR model to investigate the epidemiology of DMV in western Mediterranean striped dolphins ...

The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces

Archaeometry, EarlyView.
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

Effects of political identity activation and inaccurate metaperceptions on attitudes toward wolves

Conservation Biology, EarlyView.
Abstract Polarization between groups can undermine durable conservation outcomes. Activating group identities (i.e., an individual's sense of self derived from membership in a group) can exacerbate differences, especially when people hold inaccurate perceptions of their peers and rivals.
