How Much Do Adjuvant and Nozzles Models Reduce the Spraying Drift? Drift in Agricultural Spraying  [PDF]
Fabiano Griesang, Ricardo Augusto Decaro, Cícero Ant?nio Mariano dos Santos, Eduardo Souza Santos, Nelson Henrique de Lima Roque, Marcelo da Costa Ferreira
American Journal of Plant Sciences (AJPS) , 2017, DOI: 10.4236/ajps.2017.811188
Abstract: The spraying of herbicides in crops has become the main form of weed control. Although it means unexpected effects on non-target plants resulted by spraying drift. Thus, improvements in application techniques, as the best selection of spray nozzles and adjuvant, are essential to avoid environmental contamination and economic losses. On this work, we evaluate how much adjuvant associated with nozzles can reduce the spray drift. The nozzles used at experiment were air induction flat tip, hollow cone and twinjet and the spray liquids, which were composed of herbicide glyphosate and phosphatidylcholine + propionic acid adjuvant. Measurements were made at wind tunnel and droplet sizer, at laser diffraction method. The models of nozzles influence in droplet size characteristics and in occurrence of spray drift. The use of adjuvants reduces the spray drift only combined with the twinjet nozzle, while for the other models the adjuvant did not reduce the global spray drift at significant levels. The adjuvant reduced the spray drift until 39%, while the nozzles model reduced until 74%. Both techniques when combined were able to reduce until 80%. The model of nozzle has the biggest result on drift mitigation and the use of adjuvants can increase the drift mitigation specially with nozzles that produces smallest droplets.
Decentralization and REDD+ in Brazil
Fabiano Toni
Forests , 2011, DOI: 10.3390/f2010066
Abstract: Recent discussions on REDD+ (Reducing Emissions from Deforestation and Forest Degradation, plus conservation, sustainable management of forests and enhancement of forest carbon stocks) have raised optimism about reducing carbon emissions and deforestation in tropical countries. If approved under the United Nations Framework Convention on Climate Change (UNFCCC), REDD+ mechanisms may generate a substantial influx of financial resources to developing countries. Some authors argue that this money could reverse the ongoing process of decentralization of forest policies that has spread through a large number of developing countries in the past two decades. Central states will be accountable for REDD+ money, and may be compelled to control and keep a significant share of REDD+ funds. Supporters of decentralization argue that centralized implementation of REDD+ will be ineffective and inefficient. In this paper, I examine the relation between subnational governments and REDD+ in Brazil. Data show that some state governments in the Brazilian Amazon have played a key role in creating protected areas (PAs) after 2003, which helped decrease deforestation rates. Governors have different stimuli for creating PAs. Some respond to the needs of their political constituency; others have expectations to boost the forest sector so as to increase fiscal revenues. Governors also have led the discussion on REDD+ in Brazil since 2008. Considering their interests and political power, REDD+ is unlikely to curb decentralization in Brazil.
Internacionaliza??o e ativismo judicial: as causas coletivas
Engelmann, Fabiano;
Lua Nova: Revista de Cultura e Política , 2006, DOI: 10.1590/S0102-64452006000400006
Abstract: the article intends the analysis of the relation between the phenomenon of internationalization of law and the emergency of modalities of lawyers engaged in the judicial representation of collective causes. two dimensions are analyzed: the first one displays an exploratory panorama of the collective causes in the national and international scene, out of a survey of the profile of demands of the inter-american court of human rights and brazilian courts. the second dimension approaches, from interviews, representative cases of promotion of collective causes in the decades of 1990 and 2000. these two dimensions allow to advance the hypothesis that the national political redemocratization and the constitution of international networks of circulation of political and legal causes contribute for the definition of the profiles of judicial activism legitimated in the legal space in different periods.
Brazilian democracy and the power of "old" theories of party competition
Santos,Fabiano;
Brazilian Political Science Review (Online) , 2008,
Abstract: brazilian politics has been usually analyzed as a case full of pathologies by scholars and political journalists alike. fragmentation, volatility, clientelism and inefficiency have become bywords for describing the performance of brazil's political institutions. as a counter to this view, this work argues that the country's democracy in the post-1988 period presents enough evidence in favor of classical hypotheses about electoral politics in the contemporary world, theories that invariably are based on premises of rationality in the behavior of voters and political parties. these theories include the median voter theorem, duverger's law on the mechanical and psychological effects of electoral systems, and the model of retrospective voting. the article also contends that the passing of time has contributed to make brazilian politics more rational and efficient in the mould of older democracies.
Tradition and diversification in the uses and definitions of the law: a proposed analysis
Engelmann,Fabiano;
Brazilian Political Science Review (Online) , 2007,
Abstract: this article aims to carry out a sociological survey of the brazilian legal field in the 1990s. to this end, the relationship between the diversification of the legal sphere and the legitimisation of definitions of the law in brazil over the course of the 1990s were investigated. the close match between the differentiation of the teaching of the law, as a place for producing definitions of legal problems, and the mobilization of certain uses of the legal profession and of the careers of state during this period was analysed. this relationship allows one to gather the emergence of the academic career as a space for the production of specific conceptions and uses of the law. this process is intimately linked to the repositioning of jurists in the sphere of power in brazil, after the changes in the country's political landscape that have their institutional expression in the promulgation of the 1988 constitution.

Ciência da Informa??o , 2005, DOI: 10.1590/S0100-19652005000200011
Abstract: presents one of the first cases of conversion occurred between the main commercial software for library management available in the brazilian market nowadays. the stages of the conversion from the aleph system to pergamum system are described, as well as the main difficulties faced as well as the adopted solutions. this conversion process constitutes a case that could be possibly used as a basis for future conversions.
Internacionaliza??o e ativismo judicial: causas políticas e causas jurídicas nas décadas de 1990 e 2000

Identidade como fonte de conflito: Ucrania e Rússia no pós-URSS
Mielniczuk, Fabiano;
Contexto Internacional , 2006, DOI: 10.1590/S0102-85292006000100004
Abstract: the main argument of this paper is that the process of interaction between ukraine and russia generates a social identity of enmity, which is the source of the conflict of interests between the two countries. in order to defend the argument, a theoretical model is proposed based on the importance of ideas to the constitution of interests and on the belief that interests are determined by identities. the next task is to demonstrate why the identity between the two countries is one of enmity. the reaction of both countries towards nato expansion is used to illustrate the consequences of enmity. because identities determine interests, the relationship between friend states involves common interests and between foes divergent interests. so the perception of a threat is shared by friends while between enemies the friend of one becomes the enemy of the other. that is why ukraine cooperates with nato and russia does not accept its expansion. in order to avoid that the conflicts between ukraine and russia become a threat to europe's security, it's necessary to change the identity constructed in through their interaction.
Escolhas institucionais e transi??o por transa??o: sistemas políticos de Brasil e Espanha em perspectiva comparada
Santos, Fabiano;
Dados , 2000, DOI: 10.1590/S0011-52582000000400002
Abstract: the objective of this article is to compare the performance of the political systems in brazil and spain. in both countries the redemocratization process occurred by way of negotiation with the leaders of the out-going authoritarian regimes. the hypothesis emerging from these two experiences is that this transition format limited the range of possible institutional choices. an analysis of three fundamental dimensions in these choices, the electoral and party systems in each country, the systems of government that were adopted, and the internal organization of the respective legislative branches indicates that the history of transition fostered a concentration of decision-making power in the hands of the administration and the party leadership. thus, despite important differences in the constitutional dimension of the respective political systems, brazil and spain shaped similar procedural rules that have led to a huge public policy-making advantage for the administration.
Patronagem e Poder de Agenda na Política Brasileira
Santos, Fabiano;
Dados , 1997, DOI: 10.1590/S0011-52581997000300007
Abstract: the patterns of executive-legislative relations that prevailed during the 1946-1964 period differ from those of the post-1988 period. a brief look at the specialized literature shows that the reasons behind these changes have not yet been adequately explained. the article explores these changes more thoroughly, developing a conceptual framework for understanding the rationale of interactions between presidents, parties, and lower chamber representatives. patronage and agenda power are found to be the prime ingredients in these interactions, and important changes in the pattern of executive-legislative relations can be traced essentially to the greater agenda power enjoyed by brazilian presidents since 1988. this is reflected not only in the president?s improved capacity to make his voice heard within the legislative body but also in the greater party cohesion and discipline displayed by his support base within the lower house
