Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

A review of the FATIMA Yellow Sea field campaign research
The FATIMA marine fog project took place over the Sable Island region of eastern Canada (summer 2022) and the Yellow Sea of the Republic of Korea (ROK, summer 2023). Its goals are to improve marine fog monitoring and forecasting. Instrumented multiple research vessels, aircraft, tethered balloon and autonomous systems, ocean observation sites, and ...

Spectromicroscopy Analysis of Chicken Egg Shells
ABSTRACT Chicken egg shells, taken from farm and backyard eggs of different suppliers from different regions in Brazil were collected for chemical/structural analysis, in order to try to find if there is a relation between egg shells composition and the type of production (farm or backyard), the egg shell color and the region of production.

ABSTRACT Portable X‐ray computed tomography (portable CT) has become an important tool for the non‐destructive investigation of cultural heritage objects, particularly when in situ analysis is required. This work presents the experimental characterization and application of a transportable cone‐beam CT system designed for the inspection of large and ...

Multielemental Analysis in Rice Grains by Total Reflection X‐Ray Fluorescence
ABSTRACT Rice (Oryza sativa) is a staple food cultivated worldwide and represents a significant source of essential nutrients for humans. However, this cereal may also contain potentially toxic elements including chromium, arsenic, and lead typically present at trace concentrations (ng.g−1).

Tuning the Photochemistry of Entatic State Model Systems
We present the photochemistry of the entatic state model [Cu(DMEGqu)2]+/2+, a copper guanidino‐quinoline complex pair. By transient IR and UV/Vis spectroscopy, we obtained the lifetimes of the different excited states. We show that the structural effect of the guanidine tunes the photochemistry of this entatic state model.
