Optimizing feather hydrolysate via machine learning for microbial recycling of waste concrete fines

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The concrete industry faces significant challenges from CO2 emissions and the disposal of waste concrete fines (WCF). Microbially induced calcite precipitation (MICP) can bind WCF into bioconcrete, but the high cost of commercial culture media hinders its application.

Experimental and field evidence indicate that islet‐nesting tundra birds experience reduced nest predation and benefit indirectly from high snow goose densities

Oikos, EarlyView.
Landscape features can shape the occurrence and strength of predator–prey interactions by influencing predation risk and prey distribution. In the High Arctic, some bird species select nesting sites with physical features that impede access for their main terrestrial predator, the Arctic fox.

Extraction of Keratin from Chicken Feathers and its Application in the Treatment of Contaminated Water: an Eco-Friendly Approach

Brazilian Archives of Biology and Technology
Chicken feathers that make up 4-6% of total weight of chicken are most influential waste by-product from poultry farm and slaughter. Annual worldwide generation of several tons of feather biomass raise solid waste management concerns.

Ectopic Feather Follicles in a Chicken Teratoma or Malformation

Poultry Science, 1975
At necropsy of an 8-week-old pullet a 0.75 X 5.0 cm. yellowish, moderately firm cigar-shaped object was seen in the greater abdominal air sac lying parallel to the border of the right hepatic lobe. A capsule of 5 tissue layers (from inside outward-stratified squamous epithelium fibrous tissue, longitudinal muslce, fibrous tissue and circular muscle ...

The magnitude and economic replacement value of wild meat obtained from ‘recreational’ big game hunting in the United States

People and Nature, EarlyView.
Abstract Meat production has notable benefits for food security, nutrition and various production economies, but has elicited substantial negative environmental impacts. Recreational hunting provides an alternative to agricultural meat production for over 24 million hunters worldwide.

Japanese Silkie Fowls are Widely Distributed in the Phylogenetic Tree Derived from Mitochondrial Complete D-loop Nucleotide Sequences

The Journal of Poultry Science, 2011
The Silkie fowl (Gallus gallus var. domesticus) is distinct from other chicken breeds in terms of its appearance and behavioural characteristics. It is a Japanese native breed and has inhabited Japan since before the Edo era.

Feast or famine: How food deserts, wealth and greenspace correlate with coyote diets in Seattle, Washington

People and Nature, EarlyView.
Abstract Urban environments create unique challenges for wildlife, where dietary habits may reflect both ecological heterogeneity and societal disparities. In this study, we explored how social factors such as household income and human population density, and ecological factors such as tree canopy correlate with coyote (Canis latrans) diets in Seattle,

Diet sources of the endangered Attwater's prairie‐chicken in Texas: evidence from δ13C, δ15N, and Bayesian mixing models

Ecosphere, 2020
The Attwater's prairie‐chicken (APC; Tympanuchus cupido attwateri) was listed as an endangered species in 1967, and since then multiple studies have addressed ecological and human factors that may have limited their population recovery. In this study, we

Carbonized polymer dots with aqueous‐stable room‐temperature phosphorescence: Mechanism, matrix engineering, and application

Responsive Materials, EarlyView.
This review focuses on inorganic and organic matrices that enable aqueous‐stable room‐temperature phosphorescence (RTP) in carbonized polymer dots (CPDs). It explains the underlying RTP mechanisms, highlights how matrix engineering provides spatial confinement and bonding interactions to stabilize triplet excitons in water, and demonstrates key ...

Creating a Masterpiece. The Road to (and Beyond) Woodward and Hoffmann's 1969 Angewandte Chemie Treatise

The Chemical Record, EarlyView.
This publication describes how R. B. Woodward and Roald Hoffmann crafted their masterpiece publications. Illustrations include Woodward's first draft of the famous “Violations There are none. Nor can violations be expected of so fundamental a principle of maximum bonding.” Original but discarded text shows the stepwise paths toward the W‐H masterpieces.
