Cattle grazing on semi-natural pastures [PDF]

open access: yes, 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

Controlling Self‐Doping in Conjugated Polyelectrolyte Copolymers to Vary the Threshold Voltage in OECTs

open access: yesAdvanced Electronic Materials, EarlyView.
Two series of self‐doped conjugated polyelectrolytes are synthesized from a non‐self‐dopable building block 3MEEET and a self‐dopable building‐block 3HOT−[TMA+] or 3HOT−[SO3H] enabling precise control over the degree of self‐doping, which in turn directly governs the threshold voltage (VT) in OECTs over a wide range of 700 mV.

Decoupled Dielectric Optimization and YbOx Contact Engineering in All‐Spray‐Processed Oxide Thin‐Film Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
Fully spray‐processed oxide thin‐film transistors are advanced by decoupling dielectric quality from contact energetics. Thermochemically densified MgO suppresses defect‐mediated leakage and improves electrostatic control, while an ultrathin YbOx interlayer induces a 1.67 eV work‐function shift that boosts mobility from ∼40 to ∼94 cm2 V−1 s−1.

Suppression of Grasshopper Population Numbers with Biologically Effective Grazing Management [PDF]

open access: yes, 2004
Research comparing intensity of grasshopper infestations on grasslands with traditional grazing and twice over rotational grazing. Increased vegetation cover from rotational grazing reduces grasshopper numbers as improved grassland habitat is unfavorable

Toward a Rational Design of Conjugated Copolymers with Oxygenated Side Chains for Boosting Thermoelectric Properties

open access: yesAdvanced Energy Materials, EarlyView.
The molecular design strategy that integrates both side chain and backbone engineering in diketopyrrolopyrrole‐based conjugated polymers to identify the optimal balance between doping efficiency and microstructural order is demonstrated. Comprehensive spectroscopic, electrochemical, morphological, and structural characterizations reveal that the ...

STOCKER CATTLE OWNERSHIP VS. CONTRACT GRAZING: A COMPARISON OF RISK-ADJUSTED RETURNS [PDF]

open access: yes
Stocker cattle ownership is compared to contract grazing using stochastic simulation. Returns are evaluated for both cattle owners and caretakers in contract grazing agreements.

Dry‑Contact Trimming for All‑Perovskite Tandem Solar Cells via Solid‑Solution Homogenization

open access: yesAdvanced Energy Materials, EarlyView.
Narrow‐bandgap Sn–Pb perovskites are promising bottom absorbers for all‐perovskite tandems but suffer from Sn‐rich surfaces and depth‐dependent lattice/compositional inhomogeneity. Layered‐perovskite‐assisted dry‐contact trimming removes Sn‐rich surface species and reconfigures the Sn–Pb absorber, enabling efficient charge collection, reduced voltage ...

Swath Grazing vs Native Range Grazing for Wintering Beef Cows in South-Central North Dakota

open access: yes, 2006
Comparison study of cow performance of swath grazing (using crested wheatgrass, big bluestem, and foxtail millet) and native range ...

Lattice Coherency‐Driven (111)‐Oriented Wide Bandgap Perovskite Films

open access: yesAdvanced Energy Materials, EarlyView.
Methylammonium lead chloride (MAPbCl3)‐derived seed templates regulate wide‐bandgap perovskite crystallization through coupled thermodynamic and kinetic effects. Lattice‐coherent templating lowers the energy cost for (111) epilayer growth, while growth retardation controls crystallization kinetics, ultimately producing highly crystalline face‐up (111 ...
