Pesquisadores da área de pavimentação têm buscado soluções apropriadas para melhoria do desempenho de nossos pavimentos frente às modificações dos veículos comerciais. O Stone Matrix Asphalt (SMA) é uma excelente alternativa para elevar o desempenho dos pavimentos brasileiros. Essa mistura asfáltica, com granulometria descontínua e cerca de 70% de agregado graúdo, otimiza o contato grão a grão, aumentando consideravelmente o desempenho estrutural da camada de rolamento, principalmente quanto às deformações permanentes. Misturas do tipo SMA, em função do alto teor de ligante asfáltico, necessitam de fibras como aditivo estabilizante para que não haja segregação ou exsudação durante o processo de mistura e espalhamento. A produção de açúcar e álcool gera cerca de 270 quilogramas de bagaço por tonelada de cana-de-açúcar moída. A maior parte do bagaço é queimada nas caldeiras das usinas para produção de energia térmica ou elétrica. Estima-se que aproximadamente 20% do bagaço não é queimado. Esta pesquisa tem como objetivo principal estudar o aproveitamento do bagaço de cana-de-açúcar como aditivo estabilizante, nas misturas asfálticas do tipo SMA, produzida com asfalto modificado por borracha moída de pneus, em substituição à fibra de celulose. Para verificação dessa hipótese foi feito um estudo laboratorial e um trecho experimental foi construído para avaliação da mistura em serviço.

O critério de inclusão foi a abordagem das duas variáveis principais. Como resultado, obteve-se um conhecimento compreensivo do tema. Verificou-se que a inovação em APLs (vértice presente na gestão do conhecimento) parte da premissa de iniciativas estruturantes, voltadas para o desenvolvimento regional.

Considerando que a produção de lixo é fator gerador de diversos tipos de poluição, o presente estudo teve por objetivo verificar a destinação final dada ao lixo domiciliar gerado no município de Ituiutaba – MG. Para tanto, foi realizada uma entrevista com cinquenta moradores, de ambos os sexos, das regiões Norte, Sul, Leste, Oeste e Centro, sendo que em cada região foram entrevistadas dez pessoas que responderam a um questionário elaborado pelas pesquisadoras. As respostas obtidas permitiram perceber que em todas as 5 regiões investigadas do município (exceto na região Norte), há maior produção de lixo seco do que lixo orgânico, e ainda, que a separação desses dois tipos de lixo para a coleta seletiva é praticada em todas elas, o que mostra a consciência cidadã daqueles que se preocupam com a preservação do planeta.

The Quissamã municipality, emancipated in 1989, is located in a micro region of Macaé/RJ. The main economic activities are veal creation, cultivation of sugar cane, coconut and pineapple. The development occurred in an accelerated and disorderly manner after the emancipation, which created greater demand for water and caused problems, as reducing water depth in the main source of supply, the Feia Lagoon. The objective is to evaluate the surface water, groundwater and rainwater in the municipality, for further work on integrated management of water resources sustainable. It was created georeferenced database for mapping, temporal monitoring of the Feia Lagoon, hydrochemical analyzes in 10 points, bacteriological analyzes in 15 points and evaluation of rainfall for use of these waters. The results of monitoring of the Feia Lagoon showed that the surface current is 173 km2 while in the past was 275 km2, resulting in a loss of 37%. The average depth was 3.0 m and 1.8 m today. Groundwater indicated the presence of non-standard elements: Al, Fe, NO2, Pb, Hg, Se, Na and only two wells suitable for human consumption, in nature, with respect to bacteriological analyzes. In the rainwater analysis the average minimum was 32.8 mm in August, ranging up to a maximum average of 216.8 mm in the month of January in seven years. In conclusion the Feia Lagoon is decreasing over time, the groundwater when captured in an appropriate manner has a low cost of treatment and despite the low rainfall are the alternative use of rainwater must be considered. The assessment of water resources is necessary for future integrated management in a sustainable manner.

Sorghum [Sorghum bicolor (L.)Moench] is an African species belonging to the same family of maize. Saccharine-type sorghum is used as raw material for bioenergy (ethanol), and has high water-use efficiency. This study aimed to characterize sweet sorghum cultivars regarding physiological characteristics at different levels of irrigation. Four cultivars tolerant to drought were evaluated: Rio, Ramada, BRS 501, and BRS 506. Treatments consisted of three water availabilities: 80%, 60%, and 40% of field capacity. The study evaluated the stomatal conductance (gs), the net photosynthetic rate (A), leaf transpiration (T), and intrinsic water-use efficiency (EIUA, A/gs). It also determined the optimal quantum efficiency (Fv/Fm) of photosystem II (PSII), the quantum yield of photochemical processes in the basal PSII (Fo/Fm), and in PSII photochemical efficiency (Fv/Fo). The availability of water caused no change (P > 0,05) in transpiration in the Ramada and BRS 501 cultivars, but affected (P < 0,05) the Rio and BRS 506 cultivars, which responded positively to increased irrigation. A similar result occurred with photosynthesis, in which case the different levels of water availability had a positive influence only in the BRS 506 and Rio cultivars. The increase in irrigation resulted in an increase (P < 0,05) in stomatal conductance of the evaluated cultivars. The results of chlorophyll fluorescence showed the superiority of BRS 506, Rio, and Ramada with higher values (P < 0,05) of Fv/Fm and Fv/Fo. The different levels of water availability and cultivars did not promote (P > 0,05) change in EIUA. This methodology, common in other crops, can be used for saccharine-type sorghum in order to establish water availability in new experiments aiming at discriminating drought-tolerant cultivars.

In 1855, a political movement erupted in the city of Campos in order to create a new province in the Brazilian Empire. The new city would be named Province of Campos dos Goytacazes, based in the city of the same name. Its territory would cover the current north-northwestern areas of Rio de Janeiro State, some cities in the Zona da Mata, and southern Espírito Santo. The project started within the sugarcane economy, which was then living a moment of glory. The southern region of Espírito Santo joined the movement, but it was aborted in both the Court House and Senate. However, the myth of the region and Campos as the capital of the province and, later, of the State of Rio de Janeiro lasted until the early 21st century.

Rio de Janeiro State has been receiving a number of medium and large type investments, which may cause strong impacts in its productive and socio-economic structure, as they spread across several of its regions. Its Northern Region is expected to receive a significant portion of these investments, and its spatial configuration deeply impacted. In order to understand this process, this article argues that one must examine it in the context of the international integration pattern of Brazilian economy. It also points out that a territorial corridor of economic integration is being built, embodying Northern and Eastern regions.

The aim of this paper is to analyze the behavior of the formal labor market in Sao Joao da Barra and major cities in the region north of the state using data from the Annual Social Information (RAIS) and the General Register of Employed and Dismissed (Caged). It can be argued that the construction of the Acu Port Complex from 2007 significantly expands the formal employment in construction in Sao Joao da Barra.

The article discusses the integration of quilombola communities as a social protection action that emerged from the 1988 Constitution. This form is characterized by a broader scope of coverage to partially disengage the contributory model in effect since 1930. More specifically, we discuss the case of the Lapinha community, located in northern Minas Gerais. Backed by the so-called "Theory of Recognition," we conclude the article by indicating that the recognition of the remaining quilombos presupposes that they establish semantic bridges capable of taking them to identify common situations of deprivation, and hence derive means to guarantee the continuity of their struggles. On the other hand, it is important to critically analyze the processes from which government agencies can ensure public spaces of participatory parity able to generate recognition in the judicial sphere that, in addition to positive cultural valorization, may facilitate the redistribution of economic prospects.

This discussion focuses on the analysis of the contemporary and expressive Brazilian emigration flow to Spain. As one of the theoretical positions that allow the understanding of population displacements, the analytical category “work” was selected to orient the study. Based on this perspective, we argue on the impacts of work restructuring in human displacement due to job search, such as it has occurred with Brazilian immigrants in Spain since the late twentieth century.

The article discusses research in training and professional practice. At first, it presents an historical overview on research and knowledge production in social work, with the aim of identifying the ethical-political and theoretical-methodological "changes" experienced in this field of study. The paper also discusses the relationship between research and the current professional practice of social work, with focus on the health area. Finally, it indicates the need for research in social work to break academic tradition, and even its unidisciplinary character as, reality investigated in the health area, includes the dynamics of life.

The following essay discloses Gaston Bachelard’s principle of imagetic isomorphism and proposes it as the very foundation of the literary versant of his work. Not only does isomorphism ground his the philosopher’s reflection on the oneiric performance of the four cosmic elements, but it also sustains the phenomenological hermeneutics that launches the two poetics written by him. The constitution of a poetic space is a pledge of the tight weaving of its images. To show the literary effectiveness of this principle we present a detailed study of The Poetics of Space, unveiling the strong inner coherence of the book, which is plotted and held thanks to the imagetic isomorphism. We close our study with some comments on a short and remarkable poem by Rilke.

This article discusses the relation between hermeneutics and praxis. This relation opens a scope for reflection and discussion that has, as a main objective, an engagement in favor of practical reason, in contrast with logical-scientific arguments. Therefore, the objective of the study is to approach praxis as thought by Gadamer, in the light of a basic philosophical aim: his claim of universality for his ontology of understanding.

Discuss here the search for consensus on differences in the participatory process. Consensus involves reconciling opinions of various stakeholders: citizens, government and experts. In the same citizens group the divergence of opinions is big. We sought to examine the issue within the concepts of democracy and politics, coming at the word dissent, for which differences and conflicts are the basis of democratic practice. Conflict is exactly what capitalism tries to destroy. Identified the existence, in decision process, flexible and undeniable aspects that allow citizen participation, and the necessity for empowerment of citizens to develop autonomy and to be able to participate in decisions.

Nowadays, Variable Compensation has taken different perspectives; on one side, specialist and theorists who recommend it as a strategic tool for quality and competitive advantage for organizational success; and on the other, unfavorable opinions related to its negative impacts on organizational climate, both for the company and even on the employee. This article aims to think over the possible types of variable compensation as well as to presenting a draft proposal of a variable pay plan for the higher education teacher who works in distance education. It took into account the specificity of distance teaching and its variables, as a teaching method characterized by teacher-student separation, and mediated by technological resources.

Based on a literature review, this article discusses the relationship between health and the academic environment, addressing some of the variables identified in the daily lives of two subjects: teachers and students. We wanted to explore is the presence of Burnout Syndrome among them, considering that university education tends to be seen as a moment of greater vulnerability and challenges to young people, as new and diverse tasks imposed upon them may be a source of severe stress. To this, the teaching scenario is associated, one where we can identify elements such as labor precariousness and commodification of education, capable of generating various developments, including health of teachers. This review is part of a research project started in March of 2012 at UFF/Campos dos Goytacazes, RJ, in which the relevance of the theme is recognized, since the results of studies in this field may give rise to and / or strengthen the implementation of strategies to triggering a healthier environment for teaching, research and extension, covering both faculty and students
