Towards evenly distributed grazing patterns: including social context in sheep management strategies [PDF]

PeerJ, 2016
Background. A large proportion of natural grasslands around the world is exposed to overgrazing resulting in land degradation and biodiversity loss. Although there is an increasing effort in the promotion of sustainable livestock management, rangeland ...

Effects of social learning on foraging behaviour and live weight gain in first-season grazing calves

, 2009
When livestock are turned out to semi-natural grasslands, an effective onset of grazing is important both for animal productivity and for defoliation of the sward, which preserve the biodiversity of the vegetation.

Solvent‐Mediated Reactivity Control of Lewis‐Paired Dopants as a Versatile Strategy for Tunable and Stable Doping of Organic Semiconductors

Advanced Materials, EarlyView.
Solvent‐mediated reactivity control of Lewis‐paired dopants enables highly efficient, finely tunable, and stable doping of organic semiconductors. The optimally doped semiconductor films exhibit superior thermoelectric performance and doping stability, feature delocalized polarons along structurally ordered polymer backbones, and outperform ...

Comportamento ingestivo de novilhos em pastagem nativa no Rio Grande do Sul Ingestive behaviour of steers on natural grasslands of Rio Grande do Sul

Revista Brasileira de Zootecnia, 2007
Neste estudo avaliou-se a influência da variação nas ofertas de fitomassa ao longo das diferentes estações de crescimento na dinâmica da pastagem e no rendimento animal. Os tratamentos consistiram de quatro ofertas fixas de fitomassa (4,0; 8,0; 12,0 e 16,

Evaluating the effects of population management on a herbivore grazing conflict [PDF]

, 2013
Abundant herbivores can damage plants and so cause conflict with conservation, agricultural, and fisheries interests. Management of herbivore populations is a potential tool to alleviate such conflicts but may raise concerns about the economic and ...

n‐Type Polymer Radio Frequency Rectifiers Operating at 18.5 GHz

Advanced Materials, EarlyView.
Combining an n‐doped polymer semiconductor with wafer‐scale asymmetric planar electrodes featuring work function‐engineered contacts yields radio‐frequency diodes and rectifying circuits operating at up to 18.5 GHz. The devices combine scalable manufacturing with an operating frequency previously unattainable by large‐area organic electronics ...

PERILAKU MAKAN RUMINANSIA SEBAGAI BIOINDIKATOR FENOLOGI DAN DINAMIKA PADANG PENGGEMBALAAN

Pastura: Journal of Tropical Forage Science, 2014
Grazing land or rangeland is an “eating table” of ruminants and/or other herbivores for supporting their life. The adequacy and uptake of essential nutrients such as dry matter, protein and energy are very much determined by quality and phenology of ...

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Tingkah Laku Makan Kambing Lokal Persilangan yang Digembalakan di Lahan Gambut: Studi Kasus di Kalampangan, Palangkaraya, Kalimantan Tengah

Media Peternakan, 2004
Central Kalimantan is one of the province passed by equator line. The temperature is relatively hot, during the day time is 32 oC and 23 oC during night time. The average rainfall index is 1900-3100 mm per year. This province has remarkably wide peatland
