Pasture Productivity Trial [PDF]

open access: yes, 2017
Pasture is an essential component of the ration on organic dairy farms. Productivity of pastures is key to ensure the cattle have a plentiful source of high quality feed during the entire grazing season.

Universal In Situ Isotope Exchange Raman Spectroscopy (IERS) Methodology for Measuring Oxygen Surface Exchange Dynamics Using a Probe Layer

open access: yesAdvanced Functional Materials, EarlyView.
A bespoke multilayer thin film configuration has been designed, which overcomes the material dependency of conventional isotope exchange Raman spectroscopy (IERS). This universal IERS methodology is efficient, non‐destructive and provides additional structural information and time resolution, which can be further extended to various isotopic elements ...

Photo‐Switching Thermal and Lithium‐Ion Conductivity in Azobenzene Polymers

open access: yesAdvanced Functional Materials, EarlyView.
Light‐responsive azobenzene polymers control thermal and ionic transport simultaneously through structural transitions. UV illumination disrupts π–π stacking, converting crystalline trans states to amorphous cis configurations. Thermal conductivity drops from 0.45 to 0.15 W·m−1·K−1 while Li+ diffusivity increases 100 fold. This dual transport switching

Intelligent Pasture Cloud Management System Based on Fuzzy Mathematics PID Control

open access: yesE3S Web of Conferences, 2018
In current China, especially in western provinces, pasture management is largely backward and has low level of automation, and intelligent pasture systems are urgently needed to improve efficiency of management process and reduce operating cost.

Switchable Thermal Mid‐IR Conducting Polymer Antenna Arrays

open access: yesAdvanced Functional Materials, EarlyView.
This study presents switchable mid‐infrared plasmonic resonances in PEDOT antenna arrays. Their optical extinction peaks can be reversibly switched ‘OFF’ and ‘ON’ by tuning the polaronic charge carrier concentration via the polymer's redox state, offering modulation of optical responses in the thermal mid‐infrared range including around 10 µm ...

Environmental impacts of grazed pastures [PDF]

open access: yes, 2010
Large nitrogen (N) surplus and return of excreta-N in localised patches at high N rates in intensively grazed pasture systems markedly increases the risk of N losses to waterways and the atmosphere. Here are described the main routes of N input to grazed

Water balance complexities in ephemeral catchments with different land uses: Insights from monitoring and distributed hydrologic modeling [PDF]

open access: yes, 2016
Although ephemeral catchments are widespread in arid and semiarid climates, the relationship of their water balance with climate, geology, topography, and land cover is poorly known.

Distribution of Fasciola hepatica in Swedish dairy cattle and associations with pasture management factors.

open access: yesGeospatial Health, 2015
The geographic distribution of Fasciola hepatica infection in relation to management routines was studied in Swedish dairy herds by testing for F. hepatica antibodies with the enzyme-linked immunosorbent assay (ELISA).

Radiation‐Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System

open access: yesAdvanced Materials, EarlyView.
A novel ultrafine‐grained aluminum crossover alloy exhibits unprecedented radiation resistance and mechanical stability under extreme irradiation doses up to 100 dpa. The exceptional resilience arises from thermodynamically stable T‐phase precipitates, enabling lightweight structural materials for next‐generation spacecraft and extraterrestrial ...
