Effects of time-controlled and continuous grazing on total herbage mass and ground cover

Journal of Agriculture and Rural Development in the Tropics and Subtropics, 2016
Grazing practices in rangelands are increasingly recognized as a management tool for environmental protection in addition to livestock production. Long term continuous grazing has been largely documented to reduce pasture productivity and decline the ...

Produção de forragem e produção animal em pastagem com duas disponibilidades de forragem associadas ou não à suplementação energética Effects of forage availability and energy supplementation on herbage accumulation rate and animal yield

Revista Brasileira de Zootecnia, 2005
Neste experimento, avaliou-se o efeito de duas disponibilidades de forragem, 1.200 e 1.500 kg/ha de matéria seca (MS), e do uso de suplementação energética sobre a produção de forragem e a produção animal em pastagem de aveia (Avena strigosa Schreb ...

Droplet Triboelectrification on Liquid‐Like Polymer Brushes

Advanced Functional Materials, EarlyView.
This work investigates the triboelectrification of water droplets on polymer brush‐coated surfaces exhibiting minimal contact line pinning. Such surfaces enable the systematic study of electrode patterning and controlled changes in droplet contact area.

Tiller Defoliation Patterns under Frontal, Continuous, and Rotation Grazing [PDF]

Journal of Range Management, 1994
An investigation was conducted to characterize the intensity and frequency of tiller defoliation in 'Plains' Old World bluestem (Bothriochloa ischaemum (L.) Keng) under frontal, continuous, and 2-paddock rotation grazing systems. Frontal grazing allows cattle a continuous opportunity to graze fresh forage via a livestock-pushed sliding fence that ...

Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation

Advanced Functional Materials, EarlyView.
The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.

Desempenho de novilhos de corte em pastagem nativa com níveis de suplementação de farelo de arroz integral Beef steers performance in natural pasture with levels of full fat rice brain supplementation

Ciência Rural, 2007
Este trabalho teve por objetivo avaliar o desempenho de novilhos de corte em pastagem nativa (PN), suplementados com níveis de farelo de arroz integral (FAI) de 0; 0,5; 1,0 e 1,5% do peso vivo dos animais, num delineamento inteiramente casualizado em ...

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

Advanced Functional Materials, EarlyView.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

Comportamento ingestivo de ovelhas e cordeiras em pastagem de azevém-anual sob níveis crescentes de suplementação Ingestive behavior of ewes and ewe lambs on Italian ryegrass pasture under increasing supplement levels

Revista Brasileira de Zootecnia, 2008
Avaliou-se o comportamento ingestivo de ovelhas em lactação e cordeiras nos períodos pré e pós-desmama recebendo quatro níveis de suplemento (0; 0,5; 1,0 ou 1,5% do peso vivo), mantidas em pastagem de azevém (Lolium multiflorum Lam.) sob pastejo contínuo,

Dual‐Interface Engineering of the Source Electrode to Overcome the Intrinsic Injection‐Leakage Trade‐Off in Organic Schottky Barrier Transistors

Advanced Functional Materials, EarlyView.
A charge injection layer is introduced via RIE to decouple the dual functions of the source electrode: lowering contact resistance through doping to enhance charge injection, while SAM modification on the top surface minimizes leakage current. This strategy enables OSBTs to achieve a high on/off ratio with improved stability and performance.
