Impactos de atividades de exploração de petróleo e gás natural sobre a comunicação acústica de Mysticeti (ordem Cetacea): uma revisão

Acoustic communication is essential in mammals and has three main functions: acquisition of information about the environment, intraspecific communication and detection of predators and prey. Studies indicate that the introduction of sounds produced by anthropogenic activities such as military exercises, use of sonar and activities related to the extraction of oil and natural gas can cause interference in cetacean communication. Recently, the discovery of pre-salt tends to increase these activities. After a decade since the launch date of IBAMA`s licensing and before the imminent increase in exploration activities in Brazil, it is essential to conduct studies to monitor closely the impact of this type of activity on the marine ecosystem. Thus, this study aims to identify potential impacts that the process of oil and natural gas exploration and production might have on the communication of baleen whales. Data from literature on bioacoustics and ecology of these animals were linked with technical-scientific data regarding this type of activity. 310 documents related to the topic were analyzed. Among them only 81 documents are of academic origin, and the others mostly action plans and reports from government agencies. 80% of the documents do not have any species as a focus, and in the remaining 20%, 17% were focused on the Greenland Whale (Balaena mysticetus) and 22% on the gray whale (Eschrichtius robustus). The main impacts identified in this study were the increased frequency and amplitude of vocalization, reduction or cessation of more elaborate songs and masking problems

Avaliação da toxicidade sobre Ceriodaphnia dubia das águas dos rios Atibaia, Jaguari e efluente tratado de refinaria de petróleo

Ensuring availability of quality water for human consumption causes becomes an increasing number of studies for the analysis of effluent before and after treatment, so that its release into receiving bodies do not cause significant changes in the river water and on the biological communities related to them. The biomarkers of toxicity have long been used to verify the potential toxic effluent and its correlation with the treatment efficiency of them. In this context, the cladoceran Ceriodaphnia dubia stands out because it is a benthic aquatic organism highly sensitive to environmental changes. In this study, to evaluate the interference of the release of treated wastewater of oil refinery in Rio Atibaia, we sought to determine the toxicity on population dynamics of Ceriodaphnia dubia microcrustacean in water samples upstream and downstream from the launch site, compared with samples from Rio Jaguarí at the point of capture by the company itself and treated effluent. We have studied the number of offspring produced in 10 replicates, each starting with a test individual of up to 24 hours for each sample and correlated the results with physical-chemical and microbiological tests performed by a laboratory technician. For most tests, the results indicate that the treated effluent gives sub-lethal toxicity to the microcrustacean, as delay the onset of the reproductive cycle of the same

Controle de qualidade em estruturas na construção civil

This work is to control the quality of the structures, procedures for addressing the assembly of the formwork, scaffolding and the frame of pillars, beams and slabs. He had also intended to show that the vibration of launch and concrete items are also important, if poorly implemented can undermine the structure. This work also shows that the mapping becomes essential if there is some problem in the concrete, where concrete was launched, could be identified. And finally check the product where the structure will be evaluated for how much their quality

Comparação de custo e viabilidade técnica de obras com parede de concreto em relação a obras de alvenaria estrutural

Are being released in the construction market in Brazil ventures called Super 6. These businesses sell the promise of delivery of the apartment in six months after the launch of the venture. To meet this deadline are being deployed the constructive method of concrete walls using aluminum shapes. This system basically consists of pouring slabs and walls once, i.e. building up the wall shapes and slab joints. On the walls are used cloth, with reinforcements in vain and corners of walls and on these screens are tied the electrical boxes and conduits. For each tower is used the so-called system of half way, i.e. the system so it is sufficient to mount the Middle deck. Using a concrete which can be deformed in the next day you can lift one deck every two days with ready electric and hydraulicsystem, without having to tow the wall doing only minor fixes in the imperfections after concrete. With this system won an incredible speed in the construction of the structure reducing in almost one-third the length of the work. This work aims to compare in terms of cost-benefit of masonry structural systems and this new concrete wall system called Super 6. For this comparison will be used as parameter values used for the achievement of the Enterprise Portal of Roses of constructor Tenda which is one of the first to use concrete wall system. This project basically consists of seven towers of six floors each and will be budgeted the cost of this project if it were held in structural masonry. From these data it will be possible to make a comparison about the actual beneficial to adopt this system

Estudo da qualidade da água do Ribeirão Guaratinguetá

This paper conducts to water quality study of Stream Guaratinguetá from its source to its confluence with the River Paraiba, through the analysis of some physical, chemical and biological parameters. All tests were performed according to Standard Methods for Examination of Water and Wastewater 20th edition and compared to the CONAMA Resolution No. 357 (2005). Coliforms was the most critical parameter found in samples. The results lead to the conclusion that the biggest problem of water quality in the stream in study is the aquatic rice (rice field) and the launch “fresh” sewage

Espanha e Brasil na construção da participação democrática: clivagens e consensos

The article searches to launch some analyses and investigations on the historical reach of produced participative processes in Spain and Brazil. Evidently, both the processes if had uncurled in historical, social, economic contexts and distinct politicians, but, exactly thus, keep some approaches that we intend to give prominence in the present article. For example, the popular mobilization in the two presented cases after occurred a long period of not attendance of social demands socials. In the same way, the processes of democratic renewal of both are related with historical landmarks “end of the Cold War” and the dismantlement of the Walfare State that introduced new rationalists in the relation between governing and governed dynamic, over all in the coinage and offer of public politics. How much to the dismantlement of the Welfare State, we present, still, that in the case of Spain it provoked consequences in the modus operandi of the formularization process and implementation of public politics. It occurred, in other words, a decentralization of its formulator power to decide arrangement of public politics that started to count on the participation of social actors in the called relational city (BECERRA, 2011). In the case of Brazil, the dictatorial period (1964-1985), the fast urban growth and the generation of precarious peripheries in the main cities, the distension and the Constituent (1986-1988) had generated the enough forces of pressure so that, gradually, if it incorporated the participative arrangement in the power to decide process. We identify that in both the cases, kept the had ratios, the instauration of a critical scene of suppression/absence of formulated public politics from an interface with the social movements were the propeller spring of the transformations in the power to decide mechanisms of formularization and implementation of public politics.

Perception of brazilian citizens about Darwinism and the (Non) Influence of God in the evolutionary process

The current context is unique in relation to the teaching of evolution in Brazil and the population's perception of evolution. On the one hand, it is said often about Darwinism in various media, especially due to the relatively recent commemoration of the two hundred years of the birth of Charles Darwin and one hundred and fifty years of the launch of the book The Origin of Species. On the other hand, it is clear, in recent years, a timid movement, more worryingly, in favor of equitable approach of creationist and evolutionist theories in the classroom. This article is a part of a research whose goal is to raise the design that Brazilian respondents have about the Darwinian view (which disregards the divine influence in the evolution of the species). The instrument used for data collection is a questionnaire, type Likert scale, which consists of a series of statements in which respondents must express their degree of agreement or disagreement with each statement. In this study, we present the results of the statement. "The thought of Darwin, which does not consider God as a participant in the process of evolution, is...". Analysis correlated with data on religion and education of the respondents are also held. The results point to a tendency of respondents not to accept the Darwinian view that disregards God's interference in the evolutionary process. The data also show that respondents' choices are influenced by religion and education. The frequency of responses that tend to accept the Darwinian view (which disregards the divine participation in the evolution of the species) is higher among respondents with higher levels of education. Adherents to religions "evangelical" tend to deny this view more often than followers of other religions. Given the potential risks of inserting creationist approaches in school education, it is necessary a discussion of the possible impacts of this rejection of Darwin's thinking (which does not consider God as a participant in the evolutionary process), indicated here, in the teaching of evolution.
