Evaluation of Zinc Borate and Melamine Polyphosphate Synergy on the Rheological, Thermal, Mechanical, Dimensional, and Flame Retardant Performance of rLLDPE/CaCO3 Composites for Pipes Applications

Journal of Applied Polymer Science, EarlyView.
A synergistic flame retardant containing melamine polyphosphate and zinc borate was prepared and applied to provide rLLDPE/CaCO3 composites with superior flame retardancy. ABSTRACT The use of recycled thermoplastics is crucial for addressing environmental challenges such as waste management and sustainability.

The Effect of Environment on the Properties of the Most Massive Galaxies at 0.5 < z < 2.5 in the COSMOS-DASH Field

The Astrophysical Journal, 2023
How the environment influences the most massive galaxies is still unclear. To explore the effects of the environment on morphology and star formation in the most massive galaxies at high redshift, we select galaxies with stellar mass $\mathrm{log}({M}_ ...

Patterns of wild meat and other protein consumption in the periphery of Salonga National Park, Democratic Republic of the Congo

People and Nature, EarlyView.
Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.

The Colors and Sizes of Recently Quenched Galaxies: A Result of Compact Starburst before Quenching [PDF]

The Astrophysical Journal, 2020
Abstract We analyze the colors and sizes of 32 quiescent (UVJ-selected) galaxies with strong Balmer absorption (EW(Hδ) ≥ 4 Å) at z ∼ 0.8 drawn from DR2 of the LEGA-C survey to test the hypothesis that these galaxies experienced compact, central starbursts before quenching.

Dissecting the Mass Quenching in TNG50: Galaxy Size Determines the Quenching Mode

The Astrophysical Journal
The diminishing of star formation is accompanied by size differentiating, as quiescent galaxies are more compact than star-forming galaxies (SFGs) at fixed stellar mass. In order to understand how galaxy quenching is related to galaxy sizes, we performed

Spatial Dynamics and Lifespan of Adult Cicadas After Fire and Logging: A Radiotracking Study

Integrative Zoology, EarlyView.
This study investigates the effects of wildfire and post‐fire salvage logging on the survival, spatial behavior, and habitat selection of Lyristes plebejus cicadas in Mediterranean pine forests. A total of 63 cicadas were captured, tagged with radio transmitters, and released in three disturbance contexts: burnt‐logged, burnt‐unlogged, and unburnt ...

The Astrid Simulation: Evolution of Black Holes and Galaxies to z = 0.5 and Different Evolution Pathways for Galaxy Quenching

The Astrophysical Journal
We present new results from the ASTRID simulation from z = 3 to z = 0.5, covering the epoch of cosmic noon. The galaxy stellar mass function, as well as the black hole mass and luminosity functions in ASTRID , exhibit good agreement with recent ...

Star formation quenching in galaxies [PDF]

SCIENTIA SINICA Physica, Mechanica & Astronomica, 2017
The cosmic star formation rate density is peaked at $z\sim2$ and declines continuously since then, implying that the quenching of star formation has been the dominating process in galaxy evolution in the past $\sim10$ Gyr. As a result, the present day universe does not contain many star-bursting galaxies, which were the dominating population at $z\sim2$

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...
