Published: August 2013

The purpose of this study was to investigate the possible protective effect of N-acetylserotonin (NAS) against acute hepatic ischemia-reperfusion (I/R) injury in mice. Adult male mice were randomly divided into three groups: sham, I/R, and I/R + NAS. The hepatic I/R injury model was generated by clamping the hepatic artery, portal vein, and common bile duct with a microvascular bulldog clamp for 30 min, and then removing the clamp and allowing reperfusion for 6 h. Morphologic changes and hepatocyte apoptosis were evaluated by hematoxylin-eosin (HE) and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining, respectively. Activated caspase-3 expression was evaluated by immunohistochemistry and Western blot. The activation of aspartate aminotransferase (AST), malondialdehyde (MDA), and superoxide dismutase (SOD) was evaluated by enzyme-linked immunosorbent assay (ELISA). The data show that NAS rescued hepatocyte morphological damage and dysfunction, decreased the number of apoptotic hepatocytes, and reduced caspase-3 activation. Our work demonstrates that NAS ameliorates hepatic IR injury.

Published: August 2013

The title compounds are a class of structurally simple analogues of quaternary benzo[c]phenanthridine alkaloids (QBAs). In order to develop novel QBA-like antifungal drugs, in this study, 24 of the title compounds with various substituents on the N-phenyl ring were evaluated for bioactivity against seven phytopathogenic fungi using the mycelial growth rate method and their SAR discussed. Almost all the compounds showed definite activities in vitro against each of the test fungi at 50 μg/mL and a broad antifungal spectrum. In most cases, the mono-halogenated compounds 2–12 exhibited excellent activities superior to the QBAs sanguinarine and chelerythrine. Compound 8 possessed the strongest activities on each of the fungi with EC50 values of 8.88–19.88 µg/mL and a significant concentration-dependent relationship. The SAR is as follows: the N-phenyl group is a high sensitive structural moiety for the activity and the characteristics and position of substituents intensively influence the activity. Generally, electron-withdrawing substituents remarkably enhance the activity while electron-donating substituents cause a decrease of the activity. In most cases, ortha- and para-halogenated isomers were more active than the corresponding m-halogenated isomers. Thus, the title compounds emerged as promising lead compounds for the development of novel biomimetic antifungal agrochemicals. Compounds 8 and 2 should have great potential as new broad spectrum antifungal agents for plant protection.

Published: August 2013

Updated spatial information on the dynamics of slums can be helpful to measure and evaluate progress of policies. Earlier studies have shown that semi-automatic detection of slums using remote sensing can be challenging considering the large variability in definition and appearance. In this study, we explored the potential of an object-oriented image analysis (OOA) method to detect slums, using very high resolution (VHR) imagery. This method integrated expert knowledge in the form of a local slum ontology. A set of image-based parameters was identified that was used for differentiating slums from non-slum areas in an OOA environment. The method was implemented on three subsets of the city of Ahmedabad, India. Results show that textural features such as entropy and contrast derived from a grey level co-occurrence matrix (GLCM) and the size of image segments are stable parameters for classification of built-up areas and the identification of slums. Relation with classified slum objects, in terms of enclosed by slums and relative border with slums was used to refine classification. The analysis on three different subsets showed final accuracies ranging from 47% to 68%. We conclude that our method produces useful results as it allows including location specific adaptation, whereas generically applicable rulesets for slums are still to be developed.
Activation of cryptic metabolite production through gene disruption: Dimethyl furan-2,4-dicarboxylate produced by Streptomyces sahachiroi
Authors: Simkhada Dinesh , Zhang Huitu , Mori Shogo , Williams Howard , Watanabe Coran M H
Published: August 2013

At least 65% of all small molecule drugs on the market today are natural products, however, re-isolation of previously identified and characterized compounds has become a serious impediment to the discovery of new bioactive natural products. Here, genetic knockout of an unusual non-ribosomal peptide synthetase (NRPS) C-PCP-C module, aziA2, is performed resulting in the accumulation of the secondary metabolite, dimethyl furan-2,4-dicarboxylate. The cryptic metabolite represents the first non-azinomycin related compound to be isolated and characterized from the soil bacterium, S. sahachiroi. The results from this study suggest that abolishing production of otherwise predominant natural products through genetic knockout may constitute a means to “activate” the production of novel secondary metabolites that would otherwise lay dormant within microbial genome sequences.
ICT and Regional Growth in Europe
Authors: Korres George M.
Published: August 2013

Information and Communication Technologies (ICT) have been at the heart of economic changes for more than a decade. ICT producing sectors play an important role, notably by contributing to rapid technological progress and productivity growth. The existence of a widely accepted definition of the ICT sector is the first step towards making comparisons across time and countries possible. International comparisons are made more difficult by the lack of harmonization in the definitions of indicators. Accordingly, there is renewed interest in measuring productive efficiency to determine the degree of inefficiency (if any) and the sources of inefficiency, if it exists. This chapter provides a broad theoretical and empirical review regarding productive efficiency as well as its relationship to productivity enhancement, especially focusing on ICT and FDI investments, comprising two of the most important productivity enhancement means.

Published: August 2013

The new ICT technologies are not only quickly developing but they are also giving birth to newer ICT systems and tools. Using the Internet by means of mobile appliances increases the possibilities. The Internet network has a become essential communication tool in business processes recently. Nowadays the Internet-based applications are more and more successful in agriculture and different parts of the food industry. There are several application areas, such as extension services, precision agriculture, e-commerce, and information services, where the Internet is essential. While studying the use of Augmented Reality technology, it can be concluded that different types of services offer different possibilities. Mobile systems develop very dynamically both in regards to the speed of data transmission and services. New devices like tablets and new services like Cloud Computing, Augmented Reality, and Near Field Communication (NFC) have great potential in agriculture. Cloud Computing provides better resource management and effective cost control. Augmented Reality expands the control, and the NFC gives better personalized information exchange. However, the business assessment of these technologies must not be done only on the basis of the technology and taken out of its environment randomly, since the whole area is very complex. In this chapter, the authors show Augmented Reality and try to highlight the possibilities in agriculture.

Rural areas represent key spaces at European level from the perspective of the society’s sustainability. They represent spaces for the re-equilibration of strongly human modified societies and need to be prioritised by future political programs. Rural areas have an essential role in maintaining the integrity of natural and semi-natural ecosystems, in the preservation of key natural resources, the conservation of genetic resources, supplying a reserve of healthy areas, maintaining traditions and habits, assuring the demographical equilibrium or the alimentary security of Europe. The detailed knowledge of the processes and phenomenon specific to rural areas represent a priority of European and national sustainable development strategies. For this purpose, databases such as Corine Land Cover, EUNIS, EEA, IRENA, Eurostat, and IUCN become essential tools for the spatial implementation of this concept. They present an important background for the numerous instruments of sustaining the durability of European rural environments, such as the Natura 2000 network, Landscape European Convention, Common Agricultural Policy, different financing instruments (Interreg, Leader, Life Nature), and the green economy concept.
Using E-Learning to Address the Educational Digital Divide in Remote Communities in the EU

Published: August 2013

Digital Divide may manifest itself in terms of educational opportunities, especially in remote or insular areas. REVIT, an e-inclusion project, proved that e-learning courses can be designed, developed, and implemented to address the needs as these are described by the trainees themselves in an economically feasible, pedagogically sound, and technologically advanced way. The educational outcome of the project is not a “techie” product threatening to alienate the intended audience. Rather, the medium becomes the message and in some cases the tool employed by the citizens of remote or insular areas to establish their own online communities. This is the value brought forward by the REVIT project.

Published: August 2013

Digital traceability is a computer-based system that provides unique identification for wheat lots based on production and post-harvest records. The digital traceability system can be accessed at the Website http://www.e-rastrear.com.br. In the production step, the system is operating specifically for each plot, which corresponds to a uniform area sown with the same wheat cultivar. In the field, the record system includes the following information: crop rotations, seed treatments, fertilisation methods, monitoring of diseases and pests, and pesticide applications. Similarly, the digital post-harvest system was designed to retain information on wheat lots in all different stages of storage and processing, in addition to keeping the results of quality and technological analyses. All records can be viewed in an integrated manner according to the date of execution, and summary reports may also be obtained in a printable format.

Differential Response of Regulatory and Conventional CD4+ Lymphocytes to CD3 Engagement: Clues to a Possible Mechanism of Anti-CD3 Action?
Authors: Li Li , Nishio Junko , van Maurik André , Mathis Diane , Benoist Christophe
Published: August 2013

Several clinical trials have shown anti-CD3 treatment to be a promising therapy for autoimmune diabetes, but its mechanism of action remains unclear. Foxp3+ regulatory T cells (Tregs) are likely to be involved, but through unknown mechanistic pathways. We profiled the transcriptional consequences in CD4+ Tregs and conventional T cells (Tconvs) in the first hours and days after anti-CD3 treatment of NOD mice. Anti-CD3 treatment led to a transient transcriptional response, terminating faster than most Ag-induced responses. Most transcripts were similarly induced in Tregs and Tconvs, but several were differential, in particular, those encoding the IL-7R and transcription factors Id2/3 and Gfi1, upregulated in Tregs but repressed in Tconvs. Because IL-7R was a plausible candidate for driving the homeostatic response of Tregs to anti-CD3, we tested its relevance by supplementation of anti-CD3 treatment with IL-7/anti–IL-7 complexes. Although ineffective alone, IL-7 significantly improved the rate of remission induced by anti-CD3. Four anti-human CD3 mAbs exhibited the same differential effect on IL-7R expression in human as in mouse cells, suggesting that the mechanism also underlies therapeutic effect in human cells, and perhaps a rationale for testing a combination of anti-CD3 and IL-7 for the treatment of recent-onset human type 1 diabetes. Thus, systems-level analysis of the response to anti-CD3 in the early phase of the treatment demonstrates different responses in Tregs and Tconvs, and provides new leads to a mechanistic understanding of its mechanism of action in reverting recent-onset diabetes.

Calpain enzymes proteolytically modulate cellular function and have been implicated in inflammatory diseases. In this study, we found that calpain levels did not differ between intestinal tissues from inflammatory bowel disease (IBD) patients and healthy controls, but IBD tissues showed increased levels of the endogenous calpain inhibitor, calpastatin (CAST). To investigate the role of CAST in the immune system during IBD, mice were x-ray irradiated, reconstituted with either CAST-knockout (KO) or wild-type (WT) bone marrow, and subjected to dextran sulfate sodium–induced colitis. CAST-KO recipients with induced colitis exhibited more severe weight loss, bloody diarrhea, and anemia compared with WT controls. Histological evaluation of colons from KO recipients with colitis revealed increased inflammatory pathology. Macrophages purified from the colons of KO recipients had higher IL-6, TNF-α, and IFN-γ mRNA levels compared with WT controls. Mechanistic investigations using small interfering RNA and KO bone marrow to generate CAST-deficient macrophages showed that CAST deficiency during activation with bacterial pathogen associated molecular patterns, including heat-killed Enterococcus faecalis or CpG DNA, led to increased IκB cleavage, NF-κB nuclear localization, and IL-6 and TNF-α secretion. Thus, CAST plays a central role in regulating macrophage activation and limiting pathology during inflammatory disorders like IBD.

Sci. 93: 453–460. Heat stress can influence muscle metabolism and meat quality in animals reared for food production. From a commercial perspective, understanding the mechanism of this effect is clearly necessary. The aim of this study was to investigate the effects of different heat stress periods on serum metabolites and chicken meat quality (n=120). Plasma indicators creatine kinase (CK), glutamic-pyruvic transaminase (GPT), glutamic-oxaloacetic transaminase (GOT), insulin and glucagon and meat quality (pH, expressible moisture, cooking losses, shear force values) were evaluated. Compared with controls, the concentrations of CK and GPT increased (P<0.01) after 2 and 3 h of heat stress, respectively, whereas plasma insulin and glucagon decreased after 1 and 5 h of heat stress, respectively. The immediate pH (pHi) and ultimate pH (pHu) of the pectoralis muscles decreased (P<0.01) after 1 and 2 h of exposure to heat stress, respectively. Cooking loss, expressible moisture and shear force value increased (P<0.01) after 3, 2, and 1 h of heat stress, respectively. These data indicate that elevated plasma concentrations of CK and GPT can be used as parameters for assessing the stress level to which broilers are exposed before slaughter. The preslaughter exposure of broiler chickens to heat stress can alter muscle metabolism and membrane integrity, leading to undesirable meat characteristics. Thus, a clear understanding of the mechanisms underlying these processes will contribute to the determination of prevention strategies and the avoidance of the associated economic losses.

Li, Y. Z. and Gonyou, H. W. 2013. Comparison of management options for sows kept in pens with electronic feeding stations. Can. J. Anim. Sci. 93: 445–452. A variety of management options exist for group-housed sows and these may affect animal welfare and performance. A study was conducted to examine the effect of two management options on the performance and chronic injuries of gestating sows group-housed with electronic sow feeders (ESF). The management options examined were social management (static vs. dynamic groups) and stage of gestation at mixing (pre-implantation vs. post-implantation of embryos), with sows in stalls serving as reference. Multiparous sows (n = 1569 sow records, parity 1 to 9, PIC genetics) from 100 contemporary breeding groups were used. Group-housed sows (n = 1112 sow records) were assigned to a 2×2 factorial arrangement of management treatments. Each static group consisted of 35 to 40 sows that were grouped simultaneously and no further sows were added to the group. Dynamic groups consisted of 105 to 120 sows, with 35 to 40 sows being added to the group every 5 wk after the same number of sows had been moved out for farrowing. Results indicate that social management did not affect farrowing rate and weight change during gestation. However, sows in static pens sustained fewer (P = 0.01) skin lesions (cuts, swellings, and wounds) and had fewer incidences (P = 0.01) of lameness before farrowing than sows in the dynamic pen. Pre-implant sows had a lower farrowing rate (82.3% vs. 86.7%, P = 0.05), but had fewer skin lesions before farrowing (P <0.01) compared with post-implant sows. Neither social management nor stage of gestation at mixing affected total born, born alive or stillborn litter sizes. In general, sows group-housed with ESF performed similar to sows in stalls, but sustained fewer skin lesions before farrowing. These results demonstrate that management options can affect the reproductive performance and injuries of gestating sows in the ESF system.
Rates of yield gain of hard red spring wheat in western Canada

Published: August 2013

Thomas, J. B. and Graf, R. J. 2014. Rates of yield gain of hard red spring wheat in western Canada. Can. J. Plant Sci. 94: 1–13. The Manitoba and Saskatchewan Seed Guides dating back to 1972 represent an unused source of yield comparisons to re-examine current progress in western Canadian spring wheat cultivar yields. Adjusting for the shift in check cultivars over time showed that the yield rise due to new cultivars could be divided into two periods. Prior to the early 1990s, yields rose at a rate of about 0.33% per year; these low early rates agree with other published estimates from this period and were possibly influenced by a strong emphasis on replicating the quality of previous cultivars. From the early 1990s to 2013, yields rose by about 0.7% per year; this doubling of the earlier rate was significant based on the non-overlap of confidence intervals of comparable slopes. To compare rates published in the literature with these new rates, all slopes were adjusted to a common benchmark where mean yield = 100%. Following these adjustments, current rates in western Canada (about 0.67% per year) were comparable with a world average estimated to be about 0.62% per year. Variation in performance among Canada Western Red Spring cultivars based on the Seed Guides was significantly correlated with their on-farm yields based on Manitoba Management Plus Program (MMPP) crop insurance data (r = 0.81, n = 42). Beginning in 1991, on-farm yields rose by an average of about 1.4% per year both in Manitoba (Manitoba Management Plus Program data) and across the entire western wheat area (Statistics Canada data). This compares favorably with a world-wide rate of yield increase for wheat since 1991 of 1.16% per year. Although western Canadian on-farm yield gains were attributed to a combination of new cultivars and upgraded agronomy, the two influences were not separable in the Manitoba crop insurance data set. Opinions published in the farming press that rates of yield gain among western Canadian wheat cultivars are comparatively low were not supported by the evidence presented here.

Abstract. To investigate the influence of fresh water on phytoplankton absorption properties, the phytoplankton absorption coefficient and pigments identified by high-performance liquid chromatography (HPLC) were measured at the surface and subsurface chlorophyll a maximum (SCM) in the East China Sea (ECS), which is highly influenced by river discharge from the Changjiang during summer. For comparison, data were also collected in the Tsushima Strait (TS) at the surface and SCM. The majority of ECS surface samples taken from the low-salinity Changjiang diluted water (CDW), and even most of SCM samples taken from waters beneath the CDW, displayed significant freshwater influences. The specific absorption coefficient normalized by total chlorophyll a concentration (Tchl a), a*ph(λ), of these samples was substantially higher than values derived from global regressions between a*ph(λ) and the Tchl a. Using the pigment data derived from HPLC, the increase of a*ph(λ) was found to be mainly caused by the phytoplankton size structure, which indicated that both surface and SCM samples in the ECS still incorporated considerable portions of picophytoplankton (cyanobacteria), even though the Tchl a was high. When water from the surface and the SCM were merged, variations in the phytoplankton size-fractions and a*ph(λ) vs. Tchl a that were consistent with values for the global ocean were found in the TS but not in the ECS. Data for the ECS indicated that there was no correlation between Tchl a and the size-fraction or total pigment absorption. As a consequence, a*ph(λ) was poorly correlated with Tchl a and displayed large variability within a small Tchl a range. These findings suggest the need for care when considering the changing patterns of size-fractions vs. Tchl a and the relationship between a*ph(λ) and Tchl ain coastal regions that are significantly influenced by fresh water.

Hyperspecialization in the disciplines and the rewards for that combined with the growing mantra for first job preparation are double threats to liberal teaching and learning. Given that circumstance, the sorts of synthetic lecture classes in the humanities and social sciences that once provided the foundations of liberal learning have evaporated. Rather than lamenting what we can no longer do, we might rethink what we can do with our hyperspecialists and the desire for practicality in liberal education.

A singularidade: Reciprocidade do processo perceptivo na fenomenologia merleau-pontyana
Authors: Lima Valeria Maria N. C. de O.
Published: August 2013

O presente trabalho apóia-se nos fundamentos filosóficos da fenomenologia da percepção, no pensamento de Maurice Merleau-ponty que, partindo da hipótese de radicalização do cartesianismo, preocupado com a gênese do sentido, busca a essência do comportamento e da percepção no mundo interior do fato ocorrido (vivido) ou da própria existência, trazendo consequências para a tradição filosófica: não há mais uma essência ou ''uma maneira de ser'' acima do homem, nem objetos positivos; há sim uma essência operante, em funcionamento, o ponto comum do significante e do significado, que vai desvendando o ser no conjunto de suas experiências''juntas'', onde a vida corporal enseja o aparecimento do sujeito como corpo cognoscente, numa perspectiva ontológica de harmonia na diferenciação, enfocando simultaneamente a intersubjetividade, a comunicação, processos e vivências.
Apontamentos sobre as principais vertentes teóricas que analisam as transformações atuais do sistema capitalista de produção
Authors: Almeida Synthio Vieira de
Published: August 2013

É muito fecundo e ao mesmo tempo controverso o debate acerca das transformações que se processam no mundo capitalista atual. Em comum, as análises admitem as intensas mudanças relativas ao comportamento das forças produtivas capitalistas. Divergências no campo teórico-metodológico estabelecem as fronteiras entre Neo-schumpeteranos, que analisam as transformações em curso sob a ótica do determinismo tecnológico; a vertente Neo-smithiana, que tem por fundamento explicativo das mudanças a supremacia do mercado; a vertente culturalista, fundamentada na idéia de que a cultura determina os padrões de uso da tecnologia, organização do trabalho e estratégia de gerenciamento e a vertente Neo-marxista, também conhecida como Teoria Francesa da Regulação (Silva, 1991; Silva, 2001; Toledo, 2000). Desta forma, este artigo pretende ser uma breve síntese das correntes teóricas elencadas acima.

Esse artigo parte do pressuposto de que o delito cometido pelos jovens infratores é um ato que retrata uma experiência que toca o limite do desamparo, e se refere, sobretudo, à relação familiar e, mais especificamente, à função paterna. Estes jovens, ao se lançarem aos furtos, supõem que qualquer objeto possa saciar as suas necessidades; uma vez não atendidos em suas expectativas, apresentam traços de irritação e agressividade.
Sem medo de [o]usar: Inclusão digital em campos
Authors: Gomes Margarida Maria Mussa Tavares
Published: August 2013

O debate em torno das modificações trazidas pelas novas tecnologias tem mostrado que o conhecimento é, cada vez mais, apontado como fator determinante para o estabelecimento ou superação de desigualdades, de criação ou eliminação de empregos, de propagação ou concentração de bem-estar. Apesar disso, o ingresso na Sociedade da Informação é uma realidade distante da maioria da população mundial. Com o objetivo de debater o conceito de inclusão digital e possíveis modos de efetivá-la, são examinadas, neste trabalho, duas experiências de inclusão digital em Campos dos Goytacazes: o Projeto Informática Cidadã e o Navegar é Preciso.
Repensar o aprender: desafio do 3º milênio
Authors: Miranda Ana Bianca Rocha , Pourbaix Maridelma de Sousa
Published: August 2013

The complex educational situation, on the current knowlegde society, insisting on prioritizing only the pedagogical question, setting aside the social, political and economical perspectives, in which it is implied, can be considered a unilateral view. Based on recent studies, developed by Cognitive Sciences, we can reinforce the conception that an effective change in Education will only happen when we are able to understand what occurs in the brain when it is in learning process — it is named Cognitive Activity. Rethinking learning as a challenge of the Third Milenium means to review what “learning” really represents. We chose, then, to situate our consideration in a post-modern context, permeated by a knowledge society.
O cenário muda, mas a cena se repete...: considerações sobre o processo político-eleitoral de 2004 e as eleições de 2006, em Campos dos Goytacazes
Authors: Pantoja Silvia
Published: August 2013

This essay results from the research being developed at UCAM Campos with financial support from FAPERJ. It has two objectives. First, to analyze the mechanisms and political formulas that led to the annulment of the 2004 election’s result adopted by the two major political groups originated in the same political machine organized and strongly controlled by Anthony Garotinho for two decades. The other goal is to examine the conditions that allow us to predict the continuity of the scenario, the forms of domination and policy making which have characterized local politics since the creation of that political class.
O desencaixe moderno: o “tempo ecológico” de populações tradicionais
Authors: Huguenin Fernanda Pacheco da Silva
Published: August 2013

Although time in modernity is conceived in a linear way, there are traditional populations who associate natural rhythms to their social rhythms. This allows them to live in an ‘ecological time’. Based on the concept of disembedding, this paper discusses the disagreement generated by decrees issued by IBAMA (Brazilian Environmental Agency) regulating the fenced season of crab fishing in the South and Southeast, in relation to the local knowledge of the catadoras (female crab collectors) in Gargaú, RJ. The ‘ecological time’ of the catadoras is, then confronted with the decrees in order to demonstrate the disembedding pro moted by some modern institutions when they overlook traditional contexts.
Considerações legais sobre elaboração de um plano de contingência para vazamentos de óleos no Brasil
Authors: Mello Antônio José Plácido de
Published: August 2013

Issues related to the oceans assume vital importance for life on Earth. Environmental monitoring of prospection, exploration and oil transport is imperative in order to prevent and minimize oil and gas accidents. It is necessary to elaborate a Contingency Plan for oil spilling in the sea in the various exploration and production areas, with the collaboration of platform operators. Such strategies may be organized in two parts: the first one containing the plan’s documented policy, and the second presenting the operational plan. A good cooperation among those involved in the accident response plan is critical.
Obtenção de água potável utilizando eletrodiálise solar
Authors: Jucá Sandro César Silveira
Published: August 2013

This paper shows the main worldwide experiments in PV powered electrodialysis plants and analyses possible applications of such systems in the Brazilian Northeast region. The use of PV arrays to power electrodialysis plants for desalination of brackish water from deep wells makes sense in arid and semiarid regions. In such areas there is often an inadequate water and energy supply infrastructure along with favorable levels of solar radiation for electric generation, as is the case of the Brazilian Northeast region.
Gestão do projeto habitacional com foco em conceitos da construção sustentável
Authors: Florim Leila Chagas , Quelhas Osvaldo Luiz Gonçalves
Published: August 2013

The aim of this paper is to present an exploratory research on the benefits of eco-efficient construction systems. Awareness of the limitation of natural resources and of the environmental deterioration promoted by civil construction has given rise to concern, mostly due to the housing deficit of 5,4 million new dwellings. The environmental issue closely linked to business management is a matter of survival in a highly competitive market. In broad terms, it is a contribution to the sustainability of the planet, and to the preservation of its eco-systems and renovation cycles. This study proposes criteria for housing projects concerned with sustainable construction.
Propostas de desenvolvimento para o Norte-noroeste Fluminense em perspectiva histórica
Authors: Soffiati Arthur
Published: August 2013

This article examines the relation between nature, projects and development initiatives in the northern and northwestern regions of Rio de Janeiro, from the 16th century, with the implementation of the Hereditary Captaincy of São Tomé, to present time. The paper presents a comparative analysis between the life style of the indigenous peoples who inhabited the region and that of European settlers and conquerors. The comparison shows how the economy of subsistence contrasted with a market economy imposed in the first settling attempt. It also analyzes the great development projects and the historical construction of Rio de Janeiro and the two studied regions.

Luis Antônio Verney e as reformas culturais portuguesas: uma questão pedagógica
Authors: Atallah Claudia Cristina Azeredo
Published: August 2013

The cultural and political process observed during the 18th century presents specific characteristics which do not allow a generalized analysis. In Portugal, reforms which took place as from the Pombaline ministry met the centralized wishes of the marquis. From this perspective, this article analyses the influence the pedagogy of the Jesuit priest Luis Antônio Verney had over that period in Portugal as well as the impact it had within the intellectual and traditional circle of the Society of Jesus, which Verney left to develop his theories on teaching.
Aspectos da inserção da Igreja Universal do Reino de Deus na mídia televisiva: tecnologias do discurso a serviço da prática hegemônica
Authors: Carmo Cláudio Márcio do
Published: August 2013

This article analyses some aspects of the insertion of Igreja Universal do Reino de Deus (The Universal Church of the Kingdom of God) into the media. It started with the television program Pare de Sofrer, broadcast daily by Rede Record.My presupposition is that this new preaching space helps to marketize the discourse due to its intersemiotic aspect. The interface between some conceptions of critical discourse analysis and marketing theories may explain some aspects of discourse technologies used to intensify institutional ideologies and guarantee a consistent argumentation capable of helping unleash a persuasive and hegemonic process for the religious institution.
Aproveitamento da cinza do bagaço de cana-de açúcar como fíler em concreto asfáltico

Published: August 2013

The generation, handling and safe disposal of solid wastes has become a major concern in Brazil. The primary objective of this study was to investigate the feasibility of using sugar cane pulp ashes as filler to asphalt mixtures. The mixture’s behavior was characterized through an experimental program consisting of different industrial waste content and several test methods: Marshall stability, diametral indirect tensile test, resilient modulus and ultrasonic pulse velocity. Statistical analyses applied to the test results showed that sugar cane pulp ashes can be used as filler in bituminous mixes.

Do mito da Geometria Euclidiana ao ensino das Geometrias Não Euclidianas
Authors: Barreto Mylane dos Santos , Tavares Salvador
Published: August 2013

Non-Euclidean Geometry originated from unsuccessful attempts to prove that Euclid’s fifth postulate was a theorem. From the first four Euclidean postulates and the negation of the fifth derived other geometries whose postulates are possible in planes models, and as consistent as that in Euclidean Geometry. This article presents the Elliptical and Hyperbolic Geometry models with their postulates and concepts. A discussion of the teaching and learning of these geometries is also presented.
