Herbicide resistant weeds: A call to integrate conventional agricultural practices, molecular biology knowledge and new technologies
(Elsevier Ireland, 2019-09)
Herbicide resistant (HR) weeds are of major concern in modern agriculture. This situation is exacerbated by the massive adoption of herbicide-based technologies along with the overuse of a few active ingredients to control ...
Annual and perennial high‑Andes species have a contrasting freezing‑resistance mechanism to cope with summer frosts
(Springer, 2020)
In high-mountain habitats, summer frosts have negative consequences for plant fitness, therefore high-mountain plants have
developed mechanisms of avoidance and tolerance to cope with freezing temperatures. Various ...
Influence of the Test Specimen Diameter on the Measurement of Electrical Resistivity in Sands by Using Laboratory Devices
(Brazilian Soc Soil Mechanics & Geotechnical Engineering, 2016-05-01)
Electrical resistivity tests have long been used in geo-environmental site characterization because they provide qualitative data to identify the presence of contaminants in soil. The measurement of soil electrical resistivity ...
Life in blue: Copper resistance mechanisms of bacteria and Archaea used in industrial biomining of minerals
(PERGAMON-ELSEVIER SCIENCE LTD, 2010-07-11)
Industrial biomining processes to extract copper, gold and other metals involve the use of extremophiles
such as the acidophilic Acidithiobacillus ferrooxidans (Bacteria), and the thermoacidophilic Sulfolobus
metallicus ...
Understanding the sensing mechanism of polyaniline resistive sensors. Effect of humidity on sensing of organic volatiles
(Elsevier Science Sa, 2015-01)
Polyaniline (PANI) is the oldest and potentially one of the most useful conducting polymers. Among other technological applications, PANI films have been extensively used as resistive sensors of volatile analytes. However, ...
Assessment of the interlaminar strength of resistance-welded PEI/carbon fibre composite
(2018-02-01)
This study has as its main objective to evaluate the effectiveness of the welding process by electrical resistance in a composite poly (ether-imide) matrix reinforced with continuous fibres of carbon, from the study of the ...
Antioxidative mechanisms protect resistant strains of Staphylococcus aureus against ciprofloxacin oxidative damage
(Wiley, 2010-12)
The aim of this investigation was to determine whether the antioxidant defences protect resistant strains of Staphylococcus aureus against ciprofloxacin oxidative damage. Reactive oxygen species (ROS) were determined by ...
