Produção animal em capim papuã (Brachiaria plantaginea (Link) Hitchc) submetido a níveis de nitrogênio Animal production on alexandergrass (Brachiaria plantaginea (Link) Hitchc), submitted to nitrogen levels

Ciência Rural, 2000
Estudou-se o efeito de níveis de nitrogênio (0, 100 e 200kg/ha de N), na forma de uréia, numa pastagem de capim papuã (Brachiaria plantaginea). O sistema de pastejo foi o contínuo, com uma oferta de forragem média de 14,41kg/dia de MS/100 kg de peso vivo.

Overcoming Debye Length Limitations in Electrolyte‐Gated Transistor Biosensors Using Nanoscale‐Grooved Oxide Semiconductors Fabricated by Thermal Nanoimprint Lithography

Advanced Functional Materials, EarlyView.
Nanoscale‐grooved indium gallium oxide (IGO) semiconductors, patterned via thermal nanoimprint lithography (NIL) using CD/DVD templates, are integrated into electrolyte‐gated transistor biosensors to overcome Debye length limitations. Precisely engineered concave–convex nanostructures modulate local electrostatic potentials, extend the effective Debye ...

Multibit Ferroelectric HfZrO Memcapacitor for Non‐Volatile Analogue Memory and Reconfigurable Electronics

Advanced Functional Materials, EarlyView.
Ferroelectric memcapacitors enable non‐volatile, voltage‐programmable capacitance tuning for adaptive electronics. A TiN/HfZrO/TiN device stack demonstrates more than eight stable capacitance states within a 24 pF memory window in compact 60 ×$\times$ 60 μm2$\umu{\rm m}^{2}$ devices at low operating voltages.

SustAinimal Grazing Living Lab – a survey of grazing management on dairy farms in northern Sweden

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science
A survey was conducted on 302 Sweden dairy farms (response rate 98%) to identify grazing and grassland management strategies and main challenges to grazing in northern Sweden. The most common grazing strategy on all dairy farms was continuous grazing (59%

Flexible Polypyrrole‐Based pH Sensors via Oxidative Chemical Vapor Deposition

Advanced Healthcare Materials, EarlyView.
Oxidative chemical vapor deposition (oCVD) of polypyrrole (PPy) thin films yields flexible, electrically conductive, and biocompatible pH sensors for monitoring on‐skin biological events. The highly sensitive, oCVD PPy skin‐conformal sensors enable real‐time, spatially resolved sensing of dynamic pH changes within physiologically relevant ranges (4–9 ...
