In a major change, Brazil's Ministry of the Environment is looking for a company to help it monitor deforestation in the Amazon. "This is a surprise for everyone … crazy stuff," says Tasso Azevedo, coordinator of the Greenhouse Gas Emission Estimate System and Observatório do Clima in São Paulo and former head of the Brazilian Forest Service. The controversial proposal led to the firing of one of the ministry's top scientists, who is a vice president of the Intergovernmental Panel on Climate Change (IPCC). Since 1988, the ministry has relied on the National Institute of Space Research (INPE) to analyze land cover changes in the Amazon, which holds the world’s largest intact swaths of forest. Efforts to combat deforestation there have been the focus of worldwide interest, in large part because of the region’s rich biodiversity and the forest’s role in shaping regional climate. The ministry says INPE will continue to monitor the Amazon, but researchers worry that the $25 million annual contract will result in significant duplication of effort, a waste of scarce resources, possible confusion over deforestation rates, and create an apparent conflict of interest for the ministry. The data from INPE's remote sensing analyses helped the ministry create and enforce policies that slashed deforestation by 72% between 2004 and 2016. The flagship effort at INPE is the Program for Monitoring Deforestation of the Amazon by Satellite (PRODES), in which technicians analyze LANDSAT data to identify clear-cuts larger than 6.25 hectares and produce a yearly estimate of deforestation in the Amazon. Since 2004, INPE has added techniques to detect smaller patches of illegal cutting, and also created a program called DETER to provide monthly and weekly updates that could be used for enforcement. The long track record with PRODES and INPE's newer approaches have won praise from international experts. "Brazil is the leading country in terms of monitoring deforestation," says Matthew Hansen of the University of Maryland in College Park. "No one touches Brazil." But on 20 April, the ministry quietly issued a 160-page request for proposals for "contracting specialized services of support to the infrastructure of geoprocessing and remote sensing activities to meet the demands of environmental monitoring and geoprocessing." The 2-week deadline for proposals closes Thursday, after which the ministry will consider any bids for up to 60 days. The 12-month contract could be extended for up to 5 years. News of the proposal request was first reported Wednesday by Estadão. The decision to hire a commercial firm to do remote-sensing analysis was disputed within the ministry. The head of the program to combat deforestation, mathematician Thelma Krug, who helped create PRODES, reportedly objected to the decision. She was dismissed from her position on 19 April, the day before the request for proposals was issued. In a statement, the ministry said she wanted to spend more time on her work for IPCC. "She's a scientist who knows better than anyone in Brazil what's going on with measuring deforestation in the Amazon," says Paulo Moutinho, an ecologist at the Amazon Environmental Research Institute in Brasília. Her firing was "not good news for Brazilian society or those trying to protect the forest." In a statement yesterday, the ministry said that the purpose of the contract is to add technology, such as radar imagery, not available from INPE. The space agency will continue to monitor and estimate deforestation in the Amazon, the ministry said, and disputed that work done under the contract would be redundant with INPE’s activities. But Raoni Rajão, a social scientist at the Federal University of Minas Gerais in Belo Horizonte, says that much of the work called for by the bid request is already being done by INPE, so hiring a contractor to replicate it is "basically a waste of money." The contract would eat up 18% of the ministry's budget, which was cut 51% in March to $142 million. That's money that could be better spent fighting illegal logging, which rose 29% last year, says Carlos Souza, a remote sensing expert with Imazon, a research institute in Belém. There's also the potential for conflict of interest, critics say. The ministry would be paying a company to evaluate deforestation, which is one measure of how well the ministry is doing its job. That raises important questions, Souza says: "How transparent will the system be? Can it be verified by civil society?" INPE's methods are transparent and its analysis independent of the ministry, experts say. "If you want to save the Amazon," says Moutinho, "we need a very robust monitoring system of deforestation." Rajão, who has created an online petition to ask the ministry to cancel the request, also worries that the ministry could cherry-pick deforestation data from the contractor or INPE and highlight the better-looking numbers. Multiple sources of government information could create confusion over the status and trends of deforestation, he says. A big value of INPE’s annual deforestation estimates is that they offer a simple, clear indicator about how the world's largest rainforest is faring, says tropical ecologist Dan Nepstad of the Earth Innovation Institute in San Francisco, California. "It's become part of the national narrative on the Amazon," he says.

The present patent application relates to a method and equipment for eliminating harmonics based on two complementary techniques, namely the elimination of harmonics by selective harmonic elimination pulse-width modulation in conjunction with the multiple-wiring transformer. The association of these two resources is capable of reducing the harmonic distortion of currents to extremely low values, providing a truly unitary power factor. The technology is suitable for low and medium intensity alternating current - direct current and direct current - alternating current converters, which make interface with the electricity network and should have low harmonic distortion of the current because of the high power value involved, and also because of fragility of the electricity network (low power of short circuit at the coupling point).

ZIKAlliance is a multidisciplinary project with a global One Health approach, built: on a multi-centric network of clinical cohorts in the Caribbean, Central & South America; research sites in countries where the virus has been or is currently circulating (Africa, Asia, Polynesia) or at risk for emergence (Reunion Island); a strong network of European and Brazilian clinical & basic research institutions; and multiple interfaces with other scientific and public health programmes. ZIKAlliance will addrees three key objectives relating to (i) impact of Zika virus (ZIKV) infection during pregnancy and short & medium term effects on newborns, (ii) associated natural history of ZIKV infection in humans and their environment in the context of other circulating arboviruses and (iii) building the overall capacity for preparedness research for future epidemic threats in Latin America & the Caribbean. The project will take advantage of large standardised clinical cohorts of pregnant women and febrile patients in regions of Latin America and the Caribbean were the virus is circulating, expanding a preexisting network established by the IDAMS EU project. I will also benefit of a very strong expertise in basic and environmental sciences, with access to both field work and sophisticated technological infrastructures to characterise virus replication and physiopathology mechanisms. To meet its 3 key objectives, the scientific project has been organised in 9 work packages, with WP2/3 dedicated to clinical research (cohorts, clinical biology, epidemiology & modeling), WP3/4 to basic research (virology & antivirals, pathophysiology & animal models), WP5/6 to environmental research (animal reservoirs, vectors & vector control) , WP7/8 to social sciences & communication, and WP9 to management. The broad consortium set-up allow gathering the necessary expertise for an actual interdisciplinary approach, and operating in a range of countries with contrasting ZIKV epidemiological status.

Electrocardiography has been considered an important tool in the management of Chagas disease (ChD) patients, although its value in elderly infected patients is unknown. This study was designed to investigate the prevalence and prognostic value of electrocardiographic abnormalities in Trypanosoma cruzi infected and noninfected older adults. We studied 1462 participants in Bambuí City, Brazil, with electrocardiogram (ECG) records classified by the Minnesota Code. Follow-up time was 10 years; the endpoint was mortality. Adjustment for potential confounding variables included age, gender, conventional risk factors, and B-type natriuretic peptide (BNP). The mean age was 69 years (60.9% women). The prevalence of ChD was 38.1% (n=557). ECG abnormalities were more frequent in ChD patients (87.6% versus 77.7%, P<0.001). Right bundle branch block (RBBB) with left anterior hemiblock (LAH) was strongly related to ChD (OR: 11.99 [5.60 to 25.69]). During the mean follow-up time of 8.7 years, 556 participants died (253 with ChD), and only 89 were lost to follow-up. ECG variables of independent prognostic value for death in ChD included absence of sinus rhythm, frequent ventricular and supraventricular premature beats, atrial fibrillation, RBBB, old and possible old myocardial infarction, and left ventricular hypertrophy. The presence of any major ECG abnormalities doubled the risk of death in ChD patients (HR: 2.18 [1.35 to 3.53]), but it also increased the risk in non-ChD subjects (HR: 1.50 [1.07 to 2.10]); the risk of death increased with the number of major abnormalities in the same patient. ECG abnormalities are more common among elderly Chagas disease patients and strongly predict adverse outcomes.

Information about molecular interactions in DNA can be obtained from experimental melting temperature data by using mesoscopic statistical physics models. Here, we extend the technique to RNA and show that the new parameters correctly reproduce known properties such as the stronger hydrogen bonds of AU base pairs. We also were able to calculate a complete set of elastic constants for all 10 irreducible combinations of nearest neighbours (NNs). We believe that this is particularly useful as experimentally derived information about RNA elasticity is relatively scarce. The melting temperature prediction using the present model improves over those from traditional NN model, providing thus an alternative way to calculate these temperatures for RNA. Additionally, we calculated the site-dependent base pair oscillation to explain why RNA shows larger oscillation amplitudes despite having stronger AU hydrogen bonds. © 2012 The Author(s).
