Determination of copper at wide range concentrations using instrumental features of high-resolution continuum source flame atomic absorption spectrometry
(2010-12-01)
This work describes a method to determine Cu at wide range concentrations in a single run without need of further dilutions employing high-resolution continuum source flame atomic absorption spectrometry. Different atomic ...

Evolutionary coupling range varies widely among enzymes depending on selection pressure
(Cell Press, 2021-10-19)
Recent studies proposed that enzyme-active sites induce evolutionary constraints at long distances. The physical origin of such long-range evolutionary coupling is unknown. Here, I use a recent biophysical model of evolution ...
Designing a wider superelastic window
(American Association for the Advancement of Science, 2020-08)
Conventional metal alloys can only recover their original shape if subjected to very small elastic deformations. Superelastic alloys (also named pseudoelastic alloys) can recover their shape after deformations as great as ...
Wide dynamic range quadrature interferometer with high-gain approach and sliding mode control
(2019-09-02)
The present work concerns with the modeling, development and application of a novel control strategy based on sliding mode control for two beam quadrature interferometers, with the high-gain approach. In this case, by ...
How are endemic and widely distributed bromeliads responding to warming temperatures? A case study in a Brazilian hotspot
(Elsevier B.V., 2018-01-01)
The increase in mean global temperature is causing extensive changes in ecosystems. However, little is yet known about the heat tolerance of neotropical plant species. Here, we investigate heat tolerance variation in both ...
New constraints for the initial-to-final mass relation of white dwarfs
(2020)
We present observational constraints for the initial-to-final mass relation (IFMR) derived from 11 white dwarfs (WDs) in wide binaries (WBs) that contain a turnoff/subgiant primary. Because the components of old-enough WBs ...
The use of biosphere reserves by a wide-ranging avian scavenger indicates its significant potential for conservation
(Cambridge University Press, 2019-09-13)
The framing of environmental conservation has been changing, mainly towards a reconciliation between human needs and nature conservation. A major challenge of biosphere reserves (BRs) is the integration of biodiversity ...
