Urban wild meat consumption and trade in Central Amazonia

The switch from hunting wild meat for home consumption to supplying more lucrative city marketsin Amazonia can adversely affect some game species. Despite this, information on the amounts of wild meateaten in Amazonian cities is still limited. We estimated wild meat consumption rates in 5 cities in the State ofAmazonas in Brazil through 1046 door-to-door household interviews conducted from 2004 to 2012. With thesedata, we modeled the relationship between wild meat use and a selection of socioeconomic indices. We thenscaled up our model to determine the amounts of wild meat likely to be consumed annually in the 62 urbancenters in central Amazonia. A total of 80.3% of all interviewees reported consuming wild meat during an averageof 29.3 (CI 11.6) days per year. Most wild meat was reported as bought in local markets (80.1%) or hunted by afamily member (14.9%). Twenty-one taxa were cited as consumed, mostly mammals (71.6%), followed by reptiles(23.2%) and then birds (5.2%). The declared frequency of wild meat consumption was positively correlated withthe proportion of rural population as well as with the per capita gross domestic product of the municipality(administrative divisions) where the cities were seated. We estimated that as much as 10,691 t of wild meat mightbe consumed annually in the 62 urban centers within central Amazonia, the equivalent of 6.49 kg per person peryear. In monetary terms, this amounts to US$21.72 per person per year or US$35.1 million overall, the latter figureis comparable to fish and timber production in the region. Given this magnitude of wild meat trade in centralAmazonia, it is fundamental to integrate this activity into the formal economy and actively develop policies thatallow the trade of more resilient taxa and restrict trade in species sensitive to hunting

2 nd Brazilian Consensus on Chagas Disease, 2015

Abstract Chagas disease is a neglected chronic condition with a high burden of morbidity and mortality. It has considerable psychological, social, and economic impacts. The disease represents a significant public health issue in Brazil, with different regional patterns. This document presents the evidence that resulted in the Brazilian Consensus on Chagas Disease. The objective was to review and standardize strategies for diagnosis, treatment, prevention, and control of Chagas disease in the country, based on the available scientific evidence. The consensus is based on the articulation and strategic contribution of renowned Brazilian experts with knowledge and experience on various aspects of the disease. It is the result of a close collaboration between the Brazilian Society of Tropical Medicine and the Ministry of Health. It is hoped that this document will strengthen the development of integrated actions against Chagas disease in the country, focusing on epidemiology, management, comprehensive care (including families and communities), communication, information, education, and research

Scintillation light detection in the 6-m drift-length ProtoDUNE Dual Phase liquid argon TPC

DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6  ×  6  ×  6 m 3 liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light. The scintillation light signal in these detectors can provide the trigger for non-beam events. In addition, it adds precise timing capabilities and improves the calorimetry measurements. In ProtoDUNE-DP, scintillation and electroluminescence light produced by cosmic muons in the LArTPC is collected by photomultiplier tubes placed up to 7 m away from the ionizing track. In this paper, the ProtoDUNE-DP photon detection system performance is evaluated with a particular focus on the different wavelength shifters, such as PEN and TPB, and the use of Xe-doped LAr, considering its future use in giant LArTPCs. The scintillation light production and propagation processes are analyzed and a comparison of simulation to data is performed, improving understanding of the liquid argon properties
