BRAZILIAN SOCIAL HOUSING POLICY: TOWARD A SUSTAINABLE FUTURE
2013
In the last decade, Brazil passed through several political and economic reforms that led to significant social changes, among which the reduction of the levels of inequality and extreme poverty. Nowadays considered one of the emerging economies, the country seeks to solidify its position through wide strategies aimed to propose decisive initiatives for a balanced social development, which are deeply affecting local architecture and urban planning. In this scenario social housing design has become, since the last decade, the mirror of a national policy that is implementing robust strategies to achieve high levels of growth. The paper provides an overview of the upgrades achieved in the fiel…
Modeling Alternatives Sustainable-Energy-Policy for the Supply Chain of Wind Power in Brazil.
2020
Renewable energy studies have received high attention in the last few years due the increasing deployment of alternatives such as wind, solar and biomass, as a result of the urgency in reducing fossil fuels consumption. This situation has involved an important challenge for long-term renewables policy and energy system planning. Brazil is the richest country in terms of renewable sources in Latin American. Brazil has energy generation portfolio not much different form the Colombia one, and the understanding of this very important country will contribute to inspire other countries in the region, particularly Colombia. Since 2004 the Brazilian energy policy promotes wind power development aim…
Using simulation to analize wind power penetration: the case of North and Northeast Region
2017
Brazil is rich in renewable sources that can be used for energy generation. The renewable source of energy generation predominantly in Brazil is hydropower. However, the availability of hydropower depends on the useful volume reserves, which is subject to rainfall. Consequently, wind power is a renewable source that is being integrated into the electricity-interconnected system in Brazil. The growth of wind power generation depends on the financial resources and the delays in transmission projects. Despite the Brazilian incentives policy in wind power, the insufficient of transmission infrastructure affects to electricity price in electricity market. This paper addresses the effects of the …

Assessing the effect of transmission constraints on wind power expansion in northeast Brazil
2019
Abstract The rapid growth of the wind industry in Brazil presents new opportunities and challenges for its electricity industry. As new capacity becomes available, more transmission infrastructure is required for security of supply. The Brazilian electricity system has experienced congestion in the northeast region, affecting the coordinated expansion of transmission and new wind power capacity. This paper uses a simulation model for better assessing long-term policy synchrony of the wind industry. The simulation shows that the resulting prices are competitive in the middle to long terms.
Comparing the Antileishmanial Activity of Gold(I) and Gold(III) Compounds in L. amazonensis and L. braziliensis in Vitro
2020
Abstract Abstract: A series of mononuclear coordination or organometallic AuI/AuIII complexes (1–9) have been comparatively studied in vitro for their antileishmanial activity against promastigotes and amastigotes, the clinically relevant parasite form, of Leishmania amazonensis and Leishmania braziliensis. One of the cationic AuI bis‐N‐heterocyclic carbenes (3) has low EC50 values (ca. 4 μM) in promastigotes cells and no toxicity in host macrophages. Together with two other AuIII complexes (6 and 7), the compound is also extremely effective in intracellular amastigotes from L. amazonensis. Initial mechanistic studies include an evaluation of the gold complexes′ effect on L. amazonensis’ pl…
A Concentric CSR Roadmap Model for Host Community Relations in the Global South
2014
The purpose of this article is to find new Corporate Social Responsibility (CSR) approaches for corporate-community relationships in the global South and hence to achieve some distance from the Northern ethos. The article is based on a case study from the Brazilian pulp and paper sector. Veracel Celulose, a multinational corporation, is a joint venture between the Brazilian Fibria Celulose (formerly Aracruz Celulose) and the Swedish-Finnish Stora Enso. First, Veracel’s production impacts on the Indigenous community, the Pataxó Indians, are examined. Second, Veracel’s CSR policy and its subsequent impact are brought under closer scrutiny by juxtaposing corporate words with corporate actions.…
The cumulative effect of multiple dimensions of lifestyle on risky drinking during the Covid-19 pandemic
2021
Lifestyle impacts morbidity and mortality worldwide. Herein, we evaluated the association of a multidimensional lifestyle measure and its domains (diet/nutrition, substance use, physical activity, social, stress management, sleep, environmental exposure) with risky drinking. Also, we analyzed the cumulative effect of unhealthy domains in the likelihood of presenting risky drinking. To reach these objectives, data from a web survey conducted in Brazil and Spain was analyzed. The main outcome was risky drinking assessed by the AUDIT-C. Lifestyle was measured using the Short Multidimensional Inventory Lifestyle Evaluation (SMILE). Fixed logistic models were used to evaluate associations betwee…
Using simulation to analyze renewables penetration in Brazil
In the new global economy, renewable energy has become a central issue for the competitive. Renewables are the main source of the Brazilian electricity generation sector. This article analyzes the vulnerabilities of hydropower generation and wind power penetration in Brazil. The study presents the results obtained from preliminary analyses of renewable energy’s market penetration in Brazil. Simulation results show the climate variation effects on hydroelectricity generation as well as wind power penetration.
