Mammals, Serra da Concórdia, state of Rio de Janeiro, Brazil.

The Atlantic Forest in the state of Rio de Janeiro is extremely fragmented and reduced in its originalextension. Although there are a great number of studies related to the biome, few lists are available for this region. Thepresent study seeks to get information on the mammals of a remnant forest in Serra da Concórdia, an area from whichno information is currently available. The rapid mammal's survey was accomplished by use of pitfalls, live traps,transects, mist nets, and camera traps. We recorded 37 terrestrial species that represent 22.3 % of Rio de Janeiro statemammal species. Among the recorded species, six are endemic of the Atlantic Forest, one is endemic of the state, andeight are in the state list of threatened or presumably threatened species. The area presents great mammal richness andan increasing effort will probably reveal the presence of additional species

Outcomes from elective colorectal cancer surgery during the SARS-CoV-2 pandemic

This study aimed to describe the change in surgical practice and the impact of SARS-CoV-2 on mortality after surgical resection of colorectal cancer during the initial phases of the SARS-CoV-2 pandemic

Optical fiber accelerometer system for structural dynamic monitoring

In this study, the implementation of an optical accelerometer unit based on fiber Bragg gratings, suitable to monitor structures with frequencies up to 45 Hz, is reported. The developed optical system was used to estimate the structure eigenfrequencies of a steel footbridge, with a total length of 300 m, over the Sao Pedro Creek, located at University of Aveiro Campus, in Portugal. The acceleration records measured with this solution are compared with those obtained by traditional commercial electronic devices, revealing a root-mean-square error of 2.53 x 10(-5) G
