Grazing Intensity and Spatial Heterogeneity in Bare Soil in a Grazing-Resistant Grassland [PDF]
Rangeland Ecology & Management, 2012 Abstract We used very large scale aerial (VLSA) photography to quantify spatial patterns in bare soil in the northeastern Colorado shortgrass steppe. Using three pairs of pastures stocked at moderate (0.6 animal unit months lAUM] · ha -1 ) versus very heavy (1.2 AUM · ha -1 ) rates, we detected greater bare soil under very heavy (mean = 22.5 ...

Advanced Functional Materials, EarlyView.Ultrathin 2D indium oxide memtransistors are reproducibly fabricated via a scalable liquid‐metal‐printing process under ambient, low‐temperature conditions. The devices achieve robust, gate‐tunable bipolar memristive switching with high switching ratios at a BEOL‐compatible maximum processing temperature of 300°C. Governed by trap‐controlled transport,

Amazing Grazing: A Public and Private Partnership to Stimulate Grazing Practices in Intensive Dairy Systems [PDF]
Sustainability, 2019 In many intensive dairy regions in northwest Europe, a decline in grazing is observed. In the Netherlands, the proportion of dairy cows with access to pasture is declining, as well as the time spent grazing per cow. The decline in grazing is seen as an unwanted trend by many stakeholders and is, thus, under debate amongst dairy farmers, the dairy chain,

Advanced Functional Materials, EarlyView.The shape of guanine self‐assemblies is tuned by introducing alkyl (G8), fluoroalkyl (G8f), and oligoether (G8g) side chains into the G moiety. The scanning tunneling microscopy results and calculations show that the presence and type of the side chain strongly affect the G self‐assembly network.

PLoS ONE, 2020 Grassland biodiversity is vulnerable to land use change. How to best manage semi-natural grasslands for maintaining biodiversity is still unclear in many cases because land-use processes may depend on environmental conditions and the indirect effects of ...

High-intensity, year-round rotational grazing [PDF]
, 1995 Compared to row crops, most forage crops reduce water runoff, therefore limiting soil erosion. Forage systems also require less chemical pest control than row crops.

Van der Waals effects on grazing incidence fast atom diffraction for H/LiF(001) [PDF]
, 2016 We theoretically address grazing incidence fast atom diffraction (GIFAD) for H atoms impinging on a LiF(001) surface. Our model combines a description of the H-LiF(001) interaction obtained from Density Functional Theory calculations with a semi-quantum ...

Advanced Functional Materials, EarlyView.A reactive in situ solution complexation strategy reconstructs the surface of 2.0 eV ultra‐wide‐bandgap perovskites via proton transfer. This chemical modulation eliminates metallic defects and induces a degenerate‐like n‐type surface, establishing an Ohmic tunneling contact.

Advanced Functional Materials, EarlyView.Self‐assembled monolayers (SAMs) are promising hole‐transporting materials for organic photovoltaics (OPVs), but suffer from self‐aggregation and poor large‐area uniformity. We find that interfacial modification using nicotinic hydrazide can eliminate the residual SAM aggregates by forming energetically favorable complexes, yielding uniform SAM.
