Full Manure Recycling Risks an 18% Rise in China's Cropland N₂O Emissions Without Improved Management. [PDF]

Glob Chang Biol
By 2050, merely pursuing 100% manure recycling without improving manure‐N use efficiency could lead to an 18% increase in N2O‐N losses compared with 2019. This challenges China's current policy focus solely on manure recycling quantity, as reflected in the “14th Five‐Year Plan for National Agricultural Green Development” (2021–2025).

Effects of Replacing Fishmeal and Soybean Protein Concentrate with Degossypolized Cottonseed Protein in Diets on Growth Performance, Nutrient Digestibility, Intestinal Morphology, Cecum Microbiome and Fermentation of Weaned Piglets

Animals, 2022
The inclusion of high-quality proteins is commonly used in swine production, especially in weaned pigs. Our research investigated the effects of replacing fishmeal (FM) and soybean protein concentrate (SPC) with degossypolized cottonseed protein (DCP) on

The Grism Lens-Amplified Survey from Space (GLASS) X. Sub-kpc resolution gas-phase metallicity maps at cosmic noon behind the Hubble Frontier Fields cluster MACS1149.6+2223 [PDF]

, 2016
(Abridged) We combine deep HST grism spectroscopy with a new Bayesian method to derive maps of gas-phase metallicity, nebular dust extinction, and star-formation rate for 10 star-forming galaxies at high redshift ($1 ...

Gigantism in unique biogenic magnetite at the Paleocene-Eocene Thermal Maximum [PDF]

, 2008
We report the discovery of exceptionally large biogenic magnetite crystals in clay-rich sediments spanning the Paleocene-Eocene Thermal Maximum (PETM) in a borehole at Ancora, New Jersey. Aside from previously-described abundant bacterial magnetofossils,

Sedimentary Iron Cycling and the Origin and Preservation of Magnetization in Platform Carbonate Muds, Andros Island, Bahamas [PDF]

, 2007
Carbonate muds deposited on continental shelves are abundant and well-preserved throughout the geologic record because shelf strata are difficult to subduct and peritidal carbonate units often form thick, rheologically strong units that resist ...

Evolving a puncture black hole with fixed mesh refinement

, 2004
We present an algorithm for treating mesh refinement interfaces in numerical relativity. We detail the behavior of the solution near such interfaces located in the strong field regions of dynamical black hole spacetimes, with particular attention to the ...
