Treasures of the Serra da Jiboia (Bahia, Brazil): a new species of Racinaea and an overview of the local Bromeliaceae flora

Nordic Journal of Botany, EarlyView.
Serra da Jiboia, located in the south‐central region of Bahia, represents an important ecotone between the Atlantic Forest and the Caatinga and harbors high floristic diversity and numerous endemic species. The Bromeliaceae family, well represented in the region, stands out for its ecological importance and adaptability to various microenvironments ...

Design of a High EMC Hysteretic Current-Controlled DC/DC Boost Converter Using Chaotic Perturbations

, 2005
In this paper we aim to design a self-oscillating DC/DC boost converter operating in continuous conduction mode using an hysteretic control, and we use a chaos-based signal processing approach to improve EMC of the converter.

How many bromeliads are there? History and future perspectives of species scientific discovery in the pineapple family

PLANTS, PEOPLE, PLANET, EarlyView.
It remains unclear how many plant species are not yet recorded by science. We illustrated the process by which species of the pineapple family in tropical America have been newly described to science to date, and we estimated how many species may still await scientific discovery in this group.

Porous Modified Calcium Carbonate as an Efficient Carrier for Gallic and Ascorbic Acids in Humidity‐Activated Oxygen Scavenging Systems

Packaging Technology and Science, EarlyView.
Porous modified calcium carbonate (MCC) is presented as an efficient carrier for humidity‐activated oxygen scavengers based on gallic acid and ascorbic acid. The porous MCC structure preserves high accessibility of the active compounds, enabling effective oxygen scavenging under high relative humidity, with performance governed by loading level ...
