Concentration and composition of condensed tannins in leaves from fodder trees and shrubs in Pakistan

open access: yesJSFA reports, EarlyView.
Abstract Background The lack of dependable, high‐quality forage and animal feedstuffs in many areas of the world hampers livestock production. In these regions, farmers often rely on native fodder tree and shrub leaves as a forage source for their animals with little or no information available on nutritional factors of these feedstuffs.

Experimental Investigation of Moisture Movement During Freeze–Thaw Cycles and Its Effect on Physical Rock Weathering in Low‐Porosity Alpine Limestone

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The progressive weakening of alpine rockwalls through subcritical cracking, driven by repeated low‐magnitude stress processes, plays a key role in alpine rock weathering. Laboratory studies using acoustic emission (AE) monitoring have shown that thermal stresses from freeze–thaw cycling induce crack propagation, with recent work highlighting ...

Ionophore antibiotics and hop cones as regulators of digestion and metabolism in ruminants

open access: yesБіологічні студії
The general characteristics of ionophore antibiotics and the mechanisms of their antimicrobial action were analyzed. Two types of ionophore antibiotics are known: those that transport ions across the membrane, and those that form a channel in the cell ...

Positive Aging‐Free Quantum Dot Light‐Emitting Diodes Enabled by Single‐Source Chloride‐Doped ZnMgO Electron Transport Layers

open access: yesSmall, EarlyView.
Single‐source chloride doping of ZnMgO electron‐transport layers (ETLs) intrinsically suppresses oxygen‐vacancy traps, eliminating storage‐driven positive aging in quantum dot light‐emitting diodes. Devices deliver day‐0 peak external quantum efficiency and longer operational lifetimes, while transport and interfacial photoluminescence remain time ...

A Generalized Automated Framework for Thermal Characterization: From Bulk Materials to Complex Heterostructures

open access: yesSmall, EarlyView.
An automated MATLAB framework for inverse photoacoustic analysis enables precise thermal characterization of complex multilayer films. Application to electrodeposited CuxSe reveals a stoichiometry‐dependent thermal conductivity governed by lattice anharmonicity, not grain‐size scattering, in these superionic materials. ABSTRACT Precise determination of

The impacts of a CAP budget reform on the world economy: A CGE assessment [PDF]

open access: yes, 2013
European agricultural market support and direct payments amount to 44 billion Euros in 2012 – of which farm subsidies represent 40 billion euros. Rural development measures add 13 billion Euros to the European Union (EU) budget devoted to the Common ...

A Thermal‐Dependent Conductivity Coating for Surface Charge and Electric Field Mitigation Under Electrothermal Coupling Field

open access: yesHigh Voltage, EarlyView.
ABSTRACT The problem of gas–solid interface charge accumulation is an important reason for distorting the surface electric field and then inducing surface discharge. The temperature gradient distribution formed on the spacer during the operation of a gas‐insulated transmission line (GIL) will aggravate the surface charge accumulation, further ...

SimReg1 is a master switch for biosynthesis and export of simocyclinone D8 and its precursors [PDF]

open access: yes, 2012
Analysis of the simocyclinone biosynthesis (sim) gene cluster of Streptomyces antibioticus Tü6040 led to the identification of a putative pathway specific regulatory gene simReg1.
