Feeding and grazing management for dairy cattle: opportunities for improved production [PDF]

, 2009
An adequate feed intake is an important prerequisite to realize high milk production in dairy cows, especially during grazing. The analysis of feed intake behaviour can assist in understanding variation in daily intake and in improving its prediction ...

Spatial Control of Light‐Responsive Proteins and Optogenetics Within Hydrogels via Volumetric Bioprinting

Advanced Materials, EarlyView.
Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

Diketopyrrolopyrrole‐Based Cation as a Semiconducting Spacer in Layered Perovskite

Advanced Materials, EarlyView.
Diketopyrrolopyrrole cation incorporated layered perovskites exhibiting extended absorption profiles and enhanced charge carrier mobility with type‐II energy alignment. The improved photoconversion efficiency demonstrates the critical role of incorporating organic semiconductors in optimizing layered perovskite performance.

Impacts of fire and grazing management on South Africa’s moist highland grasslands: A case study of the Steenkampsberg Plateau, Mpumalanga, South Africa

Bothalia: African Biodiversity & Conservation, 2015
Background: Grasslands are heavily utilised for livestock agriculture and the resultant degradation through mismanagement contributes to an estimated 60% of this biome being permanently transformed. This study focused on the impact of fire and grazing in

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 Memristive Devices With Tunable Temporal Dynamics For Event‐Based Sensing

Advanced Materials, EarlyView.
Tunable volatile memristive devices can serve various neural‐inspired tasks that require different time windows of information retention. The ionic‐based volatility of the presented Pt/a‐STO/TaOx/Ta device stack can be reproducibly and controllably tuned in multiple ways.

Cattle grazing on semi-natural pastures [PDF]

, 2010
The knowledge of the grazing behaviour of cattle on Swedish semi-natural pastures and how this relates to the nutritional quality and quantity of the vegetation is low. In a situation where farming is being intensified both nationally and globally, it is

Dynamic Electrophoretic Assembly Coupled With Water‐Splitting‐Induced pH Control Enables Precision Ion Sieving Membranes

Advanced Materials, EarlyView.
A green, external‐catalyst‐free route grows defect‐free covalent organic framework membranes directly on ion‐exchange supports using an alternating electric field and in situ‐generated acid. Through a self‐regulating, self‐healing mechanism, the membranes achieve near‐complete, ultra‐fast separation of monovalent ions such as Li+, Na+, and K+, offering
