This work describes a cross section analysis using a KRITZ experiment modeled with the MCNP code for different ENDLs. The first goal is to validate the processing cross section at work temperature using the KRITZ benchmark for all the evaluated nuclear data libraries available, ENDF-VII.1, JEFF-3.1, JEFF-3.2, TENDL-2014, TENDL-2015, JENDL-4.0, RUSFOND and CENDL-3 at DEN/UFMG. The second goal is to use the same experiment (geometry, parameters, etc) at KRITZ benchmark and use it for thorium application. The new fuel based on thorium were spiked with different fissile nuclides such as 233U, 235U, 239Pu and 241Pu at 4% each fuel to increase the initial fission chain until it is self-sustained. The purpose is to compare the cross sections from the different ENDLs and find the most suitable ones. The results show that in the case of any application, the difference between ENDF/B, JEFF, JENDL and RUSFOND libraries are in a reliable interval. © 2017 Elsevier Ltd

Planning ecological restoration activities requires, first of all, a diagnostic study should address the site degradation, in order to establish the goals of the restoration project (e.g., ecosystem structure or function recovery, ecological process reestablishment). Both goals and temporal scale proposed may indicate if a project designed to recover a degraded forest site should be considered a recovery, a rehabilitation or a restoration project. Approaches may be the same for the three concepts, and one should not prevail over the two others, despite ecological restoration demands information on the ecosystem dynamics. The selection of environmental parameters as indicators of ecological restoration success should be done during the planning of activities. Choosing the most adequate restoration practices also requires information on the past land use history, which suggests distinct approaches to both distinct sites and situations. This review proposes to focus concepts and approaches which may support diagnostic studies on degraded forests, as well as the selection of the most adequate strategies for their restoration.

Ayahuasca is a beverage that has been used for centuries by Native South-Americans. Studies suggest that it exhibits anxiolytic and antidepressant effects in humans. One of the main substances present in the beverage is harmine, a beta-carboline which potential therapeutic effects for depression has been recently described in mice. "It has been shown in rodents that antidepressant medication acts by inducing neurogenesis. So we decided to test if harmine, an alkaloid with the highest concentration in the psychotropic plant decoction ayahuasca, would trigger neurogenesis in human neural cells", said Vanja Dakic, PhD student and one of the authors in the study. In order to elucidate these effects, researchers from the D'Or Institute for Research and Education (IDOR) and the Institute of Biomedical Sciences at the Federal University of Rio de Janeiro (ICB-UFRJ) exposed human neural progenitors to this beta-carboline. After four days, harmine led to a 70% increase in proliferation of human neural progenitor cells. Researchers were also able to identify how the human neural cells respond to harmine. The described effect involves the inhibition of DYRK1A, which is located on chromosome 21 and is over activated in patients with Down syndrome and Alzheimer's Disease. "Our results demonstrate that harmine is able to generate new human neural cells, similarly to the effects of classical antidepressant drugs, which frequently are followed by diverse side effects. Moreover, the observation that harmine inhibits DYRK1A in neural cells allows us to speculate about future studies to test its potential therapeutic role over cognitive deficits observed in Down syndrome and neurodegenerative diseases", suggests Stevens Rehen, researcher from IDOR and ICB-UFRJ. This study, published Dec. 6 in PeerJ, was funded by Brazilian funding agencies FAPERJ, CNPq, CAPES, FINEP, BNDES e FAPESP.

The nuclear energy area is a complex domain involving a large number of disciplines, concepts and relations. Despite its long tradition in organizing, processing and dissemination of information, reflected in important databases and international information systems, in recent decades this field has not evolved satisfactorily regarding the development of tools to standardize terminology and, consequently, concerning the extension of the theoretical and methodological framework for conceptual modeling. This fact creates an obstacle in the development of more sophisticated information systems. Starting from the systematization of ontic conceptual relations in the domain of the nuclear area, this paper presents a new way to conceptual modeling, anchored in the theoretical basis of information science. The proposed model, based on a classification principles, seeks to combine categorical and formal relations, to reaching the triadic model of relations for the nuclear area.

Carbon Management | Year: 2014

The size of forest carbon stocks and the extent of reductions in flow of net carbon emissions from forestry are key criteria for REDD+ benefit sharing and policy targeting. We perform a carbon stock-flow analysis of the 552 municipalities that make up the Brazilian Amazon forest using official data, technical procedures for estimating REDD+ emissions and removals, and fuzzy classification. We find that the municipalities held 70.2 Pg C in their forests in 2013 and were responsible for reducing the net emissions flow by 6.3 Pg CO2 from 2006 to 2013. We classify the municipalities in terms of their carbon stock-flow and identify 63 priority municipalities for REDD+ benefit sharing (those with large carbon stocks and/or high flow reductions). We assess the main national mitigation plan of REDD+ for the region and observe that it has successfully focused on the net source priority municipalities. However, the plan has not consistently focused on the net sink and large stock priority municipalities, which can lead to leakage in important carbon pools. We suggest the use of the stock-flow criteria to perform REDD+ benefit sharing among the municipalities and the inclusion of the stock-flow criteria for defining target municipalities in further revisions of the mitigation plan. © 2015 Taylor & Francis.

This work points out different aspects of a methodology that is concerned with how hypermedia content can be shared in real time through ubiquitous network and in systems context-awareness, mediated by knowledge engineering. The software components that are shared within these environments all share non-functional requirements of high reliability, availability and security. Addition to techniques of knowledge engineering and ontology engineering, these non-functional requirements need to be addressed also by the methodology. Furthermore, that type of service application also should address other modeling aspects that are related to inter-organizational aspects like culture, power and relationship. These methodological aspects are described also in this work. The benefits of applying this approach is the added value for those who need to model not just the ubiquitous software application but also the knowledge engineering aspects that allow the Hypermedia content in to be share in an ubiquitous network. © 2013 Springer-Verlag Berlin Heidelberg.

We studied the Corporate Sustainability Index (ISE) of the Brazilian Mercantile, Futures and Stock Exchange (BM&FBOVESPA), with the main objective of analyzing the performance of sustainable investments in the Brazilian stock market during the period from December 2005 to December 2010. We mainly used the following measures: Sharpe, Treynor, Jensen, Sortino, Modigliani and Modigliani, and Omega. Our results show that although sustainable investments exhibited some interesting characteristics, such as low diversifiable risk and increasing liquidity, they did not achieve satisfactory financial performance in the analysis period. As the adoption of criteria that demand high performance of companies in relation to sustainability issues becomes mandatory, the value of these investments will tend to increase.

The cluster editing problem consists of transforming an input graph G into a cluster graph (a disjoint union of complete graphs) by performing a minimum number of edge editing operations. Each edge editing operation consists of either adding a new edge or removing an existing edge. In this paper we propose new theoretical results on data reduction and instance generation for the cluster editing problem, as well as two algorithms based on coupling an exact method to, respectively, a GRASP or ILS heuristic. Experimental results show that the proposed algorithms are able to find high-quality solutions in practical runtime. © 2014, Springer Science+Business Media New York.

For most of its history, Brazil needed to import oil to complement its internal production to supply the internal demand. However, in 2007, the Brazilian Federal Government announced the discovery of huge hydrocarbon resources in the pre-salt layer of the country's Southeastern coast. This study examines the impact of this discovery accomplished by Petróleo Brasileiro S.A. (Petrobras) on patent applications in Brazil associated with upstream oil and gas technologies. Then, this article provides empirical evidence that the pre-salt discovery significantly affected patent strategizing of Multi-Nationals Companies (MNCs) operating in the upstream oil and gas industry, thereby generating a boom in patent filings in Brazil from the official pre-salt announcement onwards. © 2014 Elsevier Ltd.

Ariel Arrieta is cofounder of NXTP Labs, which hosted the LatAm Invades Silicon Valley this week in Mountain View. Back in December 2012, Google announced plans to open a $150 million data center in Chile, noting, “As Internet usage in Latin America grows, people are looking for information and entertainment, new business opportunities and better ways to connect with friends and family near and far.” But it’s not just the Internet usage that is growing in Latin America, it’s also the startup community that has begun to boom in the region. The market conditions in Latin America are improving, while the rest of the world remains stagnant or on the decline.  This, coupled with a very young population, has set up a prosperous climate for technology startups to spring up in the area.  These startups are filling a clear need that has arisen in Latin America, as Internet and mobile uses continue to increase. Half of the top 10 worldwide markets that spend the most time on social media sites, notably Facebook and Twitter, are in Latin America.  Furthermore, it’s expected that more than $4 billion will be allocated to online advertising targeting Latin America in 2014. There are plenty of startups in North America, so why care about the neighbors to the South? Because they are making a lot of noise.  Latin American countries are booming when it comes to the startup culture — and investors are beginning to take notice. We’ve heard about the Brazilian boom, but also the Chilean government declared 2013 to be the ‘Year of Innovation’ and continues to back Startup Chile, which provides $40,000 USD for startups to move to Chile for six months to start their business.  The venture incubator Movistar Innova, also in Chile, has over 600 startups registered. These two ventures are part of the reason why The Economist has dubbed Santiago “Chilecon Valley”. But the innovation doesn’t stop in Chile. Medellín, Colombia, a city once synonymous with the Colombian drug trade, has been named the most innovative city in the world by The Wall Street Journal and the Urban Land Institute. Uruguay has partnered with One Laptop Per Child to provide all of their youth in the country with computers. Brazil’s innovation agency, FINEP, has requested over $18 billion USD to support new innovative initiatives in business, education, and research. Successful startups are also coming from Argentina, where auction site MercadoLibre, went public on the Nasdaq with a US$400m IPO in 2007. Many global analysts see Latin America as an untapped market, where early stage investors can latch on to prominent startups.  The startups themselves are benefiting from global financial distress, as they have become headhunters for top talent coming from Europe and the United States. While success stories are popping up all over Latin America, investment and government issues make innovation difficult. The Latin American startup culture, which began about 14 years ago, has much to learn and much to gain by coming to the US.  Not to mention, dollars are a more stable investment than many local currencies.  With that, we are seeing more and more Latin American companies doing their IPOs in Nasdaq. Latin American companies can raise some seed funding, but they are often blocked by financial constraint and taxation issues within their own countries. So when startups need serious money, they typically turn to Silicon Valley or New York. The technology is also a concern, as Latin America is behind the global curve in terms of advancement, and this problem doesn’t seem like it will be addressed soon.  Only 14% of business leaders considered investments in technology to be a priority, though 84% of this same group agreed that technology helped drive competition, according to a study by UPS. While Latin America’s high-tech industry is small, there is still progress. For now there is no competing with Silicon Valley as the hub for innovation, investment, and opportunity in the startup world. However, big advancements are taking place in Latin America, and investors are finding untapped opportunity as well.  The startup culture in Latin America is just beginning to take off, so I’m sure we’ll see much to come in the region.
