The Effects of Recording Interval on the Estimation of Grazing Behavior of Cattle in a Daytime Grazing System

Asian-Australasian Journal of Animal Sciences, 2002
The effects of recording interval (1, 2, 3, 4, 5, 10, 15, 20 and 30 min) on the estimation of some grazing behavior variables in beef cows and calves ( rumination time>resting time. An increase in recording interval always decreased estimates of the distance walked by animals.

FEDERAL GRAZING REFORM AND AVOIDABLE RISK [PDF]

Recent rangeland reform attempts have increased ranchers'Â’ uncertainty of retaining grazing permits on federal land. This uncertainty is analyzed with a model of grazing on federal land.

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

AN EVALUATION OF THE PRIA GRAZING FEE FORMULA [PDF]

The federal grazing fee is currently set using the Public Rangeland Improvement Act (PRIA) fee formula established in 1978 and modified in 1986. The formula is adjusted annually using indices of private land grazing lease rates (Forage Value Index, FVI),

Volatile ZrO2 Antiferroelectric Tunnel Junctions for Rapid, Energy‐Efficient Physical Reservoir Computing

Advanced Science, EarlyView.
An antiferroelectric tunnel junction serves as a reservoir computing node, where field‐induced phase transitions and spontaneous ZrO2 relaxation deliver nonlinear fading memory. An In‐Ga‐Zn oxide interlayer enlarges the memory margin and multibit state richness.

Influence of supplementation method on forage use and grazing behavior by beef cattle grazing bluestem range

Journal of Animal Science, 1991
Two 25-d trials (late summer and early winter) were conducted to determine the influence of supplementation method on forage use and grazing behavior. Fifteen ruminally and 12 esophageally fistulated steers (316 and 400 kg, respectively) were blocked by weight and assigned randomly to one of three treatments: 1) self-feeding supplement (via Calan gates)

Wake‐Up and Fatigue under Electrical Cycling in HfO2‐Based Ferroelectrics: Mechanisms and Strategies toward Reliable Devices

Advanced Science, EarlyView.
HfO2‐based ferroelectrics exhibit wake‐up and fatigue behaviors during electrical cycling, significantly affecting device endurance and reliability. These phenomena are governed by defect dynamics, including oxygen vacancy redistribution and charge trapping.

Voltage‐Driven Non‐Volatile Interconversion Between Giant Single‐Domain and Multidomain Magnetic States in a Multiferroic Heterostructure

Advanced Science, EarlyView.
Non‐volatile voltage control of magnetic configurations is achieved in a strain‐coupled multiferroic heterostructure. Voltage pulses reversibly interconvert giant single‐domain and multidomain magnetic states, which remain stable at zero applied voltage. ABSTRACT Voltage control of magnetic states in multiferroic heterostructures represents a promising
