The symbology of the sea in Lygia Bojunga Nunes's work: a reflection on utopian and dystopian framing

The ambivalent image of the sea is recurrent in Bojunga Nunes’s work. It receives a lot of symbolic meanings in her production, being sometimes a positive and sometimes a negative element. Thus, the sea is used in a utopic way, as a place for pleasure and leisure, and in a dystopic way, as scenery of a rite of passage, which includes the pain and suffering, part of the rite of passage that characterizes the bildungsromans. So, if in some texts the sea assumes a utopic character, being a place of snuggle, security, the ideal to reach, in others it is represented as dystopic, a place of distress, asphyxia and death. In this text we will study the hypothesis that, even in its dark symbolic meaning, in the author’s work the sea is an element of reflection and revelation. Thereby, it assumes metaphorically a sense of magnification of the reader’s expectative, being an element of emancipation. The objective of this text is to present a reflection on the sea’s symbolism on the mentioned texts and its importance for the reader’s formation.

Strategic planning for dairy cattle: SWOT analysis applied to a property of a farmers' association in Dracena, São Paulo state, Brazil

The sector of milk production in Brazil is very heterogeneous (high-tech in large scale X family properties). This study aimed to develop a diagnostic as a basis for a strategic plan to face the challenges inherent in operating a dairy farm in property of a farmers' association in Dracena, São Paulo, Brazil. It was observed that the association needs a more efficient guidance in the marketing, production and finance areas, not to compromise the search for new markets and continued growth in activity.

Genistein reduces the noxious effects of in utero bisphenol A exposure on the rat prostate gland at weaning and in adulthood

Bisphenol A (BPA) is one hormonally active chemical with potential deleterious effects on reproductive organs, including breast and prostate. In contrast, genistein (GEN) is the major phytoestrogen of soy that presents potential protective effects against hormone-dependent cancers, including that of the prostate. Thus, pregnant Sprague-Dawley rats were treated with BPA at 25 or 250 μg/kg/day by gavage from gestational day (GD) 10-21 with or without dietary GEN at 250 mg/kg/chow (∼5.5 mg/kg/day). Then, male offspring from different litters were euthanized on post-natal day (PND) 21 and 180. At PND21, BPA 25 exposure induced early prostatic changes while dietary GEN attenuated some deleterious actions this xenoestrogen on epithelial cell proliferation levels, androgen receptor expression and prostatic architecture in male offspring. At PND180, a significant increase in incidence of prostatic multifocal inflammation/reactive hyperplasia and atypical hyperplasia were observed in male offspring from dams that received BPA 25. On the other hand, maternal GEN feeding attenuated some the adverse effects of BPA 25 on prostate disease at late-in-life. This way, the present findings point to preventive action of dietary GEN on deleterious effects of gestational BPA exposure in both early and late prostate development in offspring F1.

El desarrollo tecnológico en la vida cotidiana: influencias sociales comprendidas por universitarios brasileños

This paper, trying to understand how society influences technological development in daily life, developed a theoretical model, translated into a Likert scale, to be applicable to Brazilians undergraduate students from Sao Paulo. The social indicators that are presented in this scale were generated from content analysis in the process of construction and presentation of qualitative results which are the goals of this article. So it is possible to point out that the sample of undergraduates students surveyed points to the government, educational and research institutions, companies and citizens, as the main social actors strictly responsible for technology choices. The result allows brief reflections on the social influence on technology choices in daily life.

Preventing chaotic motion in tapping-mode atomic force microscope

During the last 30 years the Atomic Force Microscopy became the most powerful tool for surface probing in atomic scale. The Tapping-Mode Atomic Force Microscope is used to generate high quality accurate images of the samples surface. However, in this mode of operation the microcantilever frequently presents chaotic motion due to the nonlinear characteristics of the tip-sample forces interactions, degrading the image quality. This kind of irregular motion must be avoided by the control system. In this work, the tip-sample interaction is modelled considering the Lennard-Jones potentials and the two-term Galerkin aproximation. Additionally, the State Dependent Ricatti Equation and Time-Delayed Feedback Control techniques are used in order to force the Tapping-Mode Atomic Force Microscope system motion to a periodic orbit, preventing the microcantilever chaotic motion

Trabalho e saúde: o cotidiano dos catadores de lixo reciclável

The present article is an investigation / action regarding the working conditions for pickers of recyclable waste in a medium-sized city in the state of São Paulo, mainly on the health / illness process, problems related to social security and conditions of autonomy and citizenship. We use the constructs of social psychology as theoretical. The recycling of urban garbage, as the literature indicates, is not being treated as just part of the solution to environmental problems, but also has been characterized as a source of income and livelihood for many people, with no other options in life. From the interviews were semistructured, and with the method of analysis the meaning core were identified issues related to the holding of by scrap collectors, prejudice existing in relation to the activity performed, poor housing conditions, the need to social recognition and the difficulty of recyclable garbage collectors in forming a group in which they can articulate and fight for their demands. With this study, we intended to indicate suggestions for improvements in these health professionals and encourage individual and collective reflections on the condition of meetings and also through the distribution of leaflets.

A sewage sludge co-composting process using respirometric monitoring method in hermetic rotary reactor

This paper has the objective of monitoring the biological activity of composting process of sewage sludge, sugarcane bagasse and ground coffee in a hermetic rotary reactor using the respirometric method in laboratory scale, in order to obtain parameters and system design for large scale projects. Another particularity of this study is the use of a hermetic reactor with gas purging cycles. Purging was performed when the percentage of oxygen reached less than 5%, thus eliminating the gaseous mixture (with elevated CO2 ratio) and the introduction of environmental air with around 21% of O2, successively until the compost was stabilized. The average purge intervals obtained were 29 h and 2 min with reactor rotation frequency of 15 min. The time of the compost stabilization was optimized in 60% if compared to the 90 days in the traditional method. The results obtained can be used to design the process in industrial scale using a simple O2 gas analyzer.
