Exploiting antipredator behavior in white‐tailed deer for resource protection

open access: yesWildlife Society Bulletin, 2012
Effects of visual obstruction on white‐tailed deer (Odocoileus virginianus) include enhanced vigilance and flight‐initiation distances. Prior work suggests that artificial visual barriers might enhance perceived risk of predation to deer.

Investigation of the feeding process at concentrate feeding stations for horses in group housing [PDF]

open access: yes, 2018
Computer-controlled concentrate feeding stations are increasingly used to guarantee an individual feed supply of group-housed horses. Blocking times caused by horses remaining in the feeding station without concentrate allowance are classified as a ...

Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a

Effect of supplementation frequency in feeding behavior, displacement patterns and forage intake of beef heifers

open access: yesSemina: Ciências Agrárias, 2017
Our work was carried out to evaluate forage intake, feeding behavior and displacement patterns of beef heifers fed exclusively on pasture or receiving oat grain, either daily (“frequent”) or from Monday to Friday (“infrequent”), in two phenological ...

Shoot growth responses at supplementary feeding stations for moose in Norway [PDF]

open access: yes, 2015
Moose browsing pressure in the vicinity of supplementary winter feeding stations eventually declines over time. It is believed that continual winter browsing over multiple years causes locally reduced shoot growth and forage availability for moose ...

Population Density of Free-Roaming Cats in Relation to Feeding Stations on Hayden Island

open access: yes, 2021
Free-roaming cats have a devastating impact on wildlife populations with stray/feral cats being the most problematic. In some areas, community members provide these cats with food, water, and shelter often in conjunction with a trap, neuter, return (TNR)

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Positively Charged Polymer‐Brush MOFs for Large‐Area, Pressure‐Resistant Gas Separation Membranes

open access: yesAdvanced Materials, EarlyView.
A universal POPA strategy enables positively charged polymer‐brush MOFs with self‐adaptive interfacial interlocking to resist aggregation under fast processing. This design ensures seamless dispersion within large‐area selective layers, achieving 1 m‐wide roll‐to‐roll fabrication of pressure‐resistant MMCMs with tunable CO2 separation performance ...
