The ceramic pigments are colored inorganic substances that during the process of dispersion in the ceramic glazes and subsequent calcination, are stable against physical and chemical attack. Therefore, they are crystalline compounds applied in the ceramic industry for coloring vitreous base. In this study, the Pechini method was used for obtaining the pigment CuCr2O4 with heat treatment at the tempera-tures of 800, 900 and 1000 ° C. The powder pigments were characterized on their structural, morphological and color-imetric aspects. The thermal analysis conducted on an amorphous precursor in a TG / DTA indicates the weight loss in the entire temperature range investigated, with characteristic exothermic peak of the elimination of the organic composition of the precursor around 300°C. The development of the crystalline phases were investigated by XRD, using a diffractometer with Cu Ka radiation and graph-ite monochromator, where it was observed the presence of crystalline phases corresponding to Cr2O3 and CuCr2O4.The measurements of the specific surface area of the powders pigments were carried out in an equipment Micromeritcs, model ASAP 2000, using N2 as gas of adsorp-tion/desorption. The colorimetric measurements of the pigments were made in a colorimeter Gretac Macbeth Color-eye spectrophotometer 2180 / 2180UV in CIELAB standards. Based on the obtained results, it can be verified the thermal stability of the powder pigments of green coloration, which enables it as an alternative to the materi-als currently used in the manufacture of ceramic tiles.

The balneability conditions were investigated through samples collected in seven monitoring points along the Natal-RN coast during the period of 2004-2009. Temporal evolution of balneability conditions and annual percentage of proper bathing conditions were analyzed according to the Brazilian standards established by the CONAMA 274/00 resolution. Results showed that all but the Via Costeira/Mãe Luiza beach presented good environmental quality. The beaches of Barreira d’Água and Cacimba do Boi, both located at Via Costeira, presented the best environmental quality, showing each year proper bathing conditions over 98% and 92%, respectively. In contrast, Mãe Luiza beach repeatedly presented extremely high MPN of faecal coliforms, which means it presented a poor balneability condition for most of the period under analysis. Precipitation may be considered one the factors influencing balneability conditions, however we could not establish a clear relationship between the accumulated amount of weekly precipitation and the MPN of faecal coliforms for the sampling points considered.

Moments before retirement comprise a unique process and it differs from person to person. Nevertheless, as we are part of a society which overrates the labor and the professional role and which does not prepare us for satisfactory experience of free time, this has contributed to transform the time when you stop working into moments of stress, that brings fear, doubts and much of a bother. This paper reports a case study about the experience of program implementation entitled: “New Time – Preparation Program for the Post-career”, started in 2008 at the Federal Institute of Education, Science and Technology of the state of Rio Grande do Norte/Central Campus Natal, which has the goal of allowing workers, who will retire within three years, to deal with the end of their institutional activity competently and with creativity. The implementation experience, the activities planning, the New Time Program detailing operation, and their goals achievements will be displayed. For the purposes of this article, we adopted a descriptive methodology, involving the use of standardized techniques of recording and questionnaires, which were collected through the testimonies of participants in each of the three graduating classes. It concludes that the program has proved to be an important facilitator in decision making and awareness of the need for planning a life project directed to an active retirement at post-career, corroborating to the relevance of this type of social responsibility action made by the organizations.

Introduction: More than half of the Brazilian population are women. However, the female population is in disadvantage when they have to look for a job. Most of them do not have the necessary skills and professional experience. The Thousand Women Program was introduced in the Federal Institutes (IFs) to provide the basis for a social inclusion policy so that women in situation of social vulnerability could have access to professional education, employment and income. Objective: To assess the subjective well-being of the participants in the Thousand Women Program , in the city of Barbacena-MG. Methods: After being approved by the Research Ethics Committee, 41 women from 5 different neighborhoods of the city of Barbacena were selected, following the predetermined inclusion criteria. On the application day, the participants answered the General Health Questionnaire (GHQ-12), the Anxiety, Depression and Self-Esteem scales, the Positive and Negative Affect Scale, and the Satisfaction With Life Scale, which were all validated for use in Brazil. After 3 and 6 months, respectively, all women were reevaluated. Results: In 3 and 6 months, the students showed improvement in items that assessed their overall health. Although not statistically significant, clinically, satisfaction with life has increasingly improved during the participation in the program.

Although the open literature presents advances in methods for folates determination, these publications usually covers fortified foods. Up to date, most of the published HPLC methods for soluble B-vitamins determination use buffer solutions and surfactants as mobile phase, making the quantification procedure laborious and expensive. Thus, in the present work, a simple method based on Solid Phase Extraction (SPE), followed by separation by high performance liquid chromatography was developed and validated in order to quantify the levels of folate naturally present in the cashew apple juice. The separation was achieved using water and a small amount of acetonitrile in gradient flow as solvent elution system. The developed method presented the necessary requirements for its application as a laboratory protocol to quantify folates in cashew apple juice: good linearity, precision and accuracy. The cashew apple juice samples analyzed in this study presented folate contents ranging from 0.74 to 1.32 mg/L, making cashew apple juice a good folate source.

Methodologically, our research was conducted during physical education classes through exhibitions dialogical, readings, seminars, lectures, and experiences of different physical techniques. Such procedures have become essential to know and reflect on some aspects related to the body, such as: Beauty, Health, sensuality, among others. We believe that our investigation led us to clarify, along with students, knowledge and expertise related to the body and embodiment, helping to overcome alienation and limited vision of the theme in question.

Based in the importance of epistemology in conducting researches in every area of study and its knowing by the researchers, this research described what were the epistemological approaches more present in dissertations of a Management Post-Graduation Program in the Brazilian northeast in the period of 2005 to 2007. Through the construction of a collection data instrument, based in the focus proposed by Ivone (2005) and enriched by the Demo’s (1981) epistemological focus, was done a content analysis in 49 dissertations produced in the period studied, specifically of problematic, characterizing, therefore, the research as a documental qualitative research. Was detected that the epistemological approach more present in dissertations is the positivist approach, present in empirical-positivist hypothetical-deductive and empirical-positivist approaches, concluding, hence, that the necessity of empirical verification is very present in the analyzed researches, showing the strong positivist influence in the analyzed Post-Graduation Program. Thus, is possible to perceive that is wide the difficulty to expel a necessity of a cause and effect empirical evidence.

Communication systems that use air (space) as means of data transmission are subject to problems interference and lack of sight, being often, require a filter (equalizer) to offset the adverse effects introduced by the communication channel. Initially, this paper presents the basics of digital communication. Next is an analysis of the use of widely linear processing applied to the equalization of communication channels using fractionally spaced equalizer (FE). Simulation results show that this approach can effectively solve the problem of equalization of digital communication channel.

This study aimed to portray the real social and environmental condition of the population from Sales-SP. The survey, conducted through a household survey (with application of the questionnaire) and direct observation of the researchers, evaluated the exposure of individuals to environmental insults and adverse health effects "physics" and "social" these aggressions. In addition, we sought to identify the perceptions of residents about these aggressions and opinions related to environmental issues. The results expose conditions of vulnerability experienced by families who suffer from job insecurity and unhealthy conditions of their dwellings. In addition, situations become apparent indifference of the public and identifies little community participation in identifying local environmental problems and preserving the environment. We conclude that there is a need that interventions related to improving the quality of life of people living in this neighborhood are performed, with emphasis on basic sanitation and environmental education. In a more general instance, this study raises discussions about the importance of checking and indicators that provide an assessment of environmental quality in urban areas, using these as a foundation for the planning of cities and essential to improve the quality of life in cities.

The Brazil has gone from a rural country to an urban society, industry and services in a short time. The society's awareness on environmental issues, working conditions and the risk of accidents which may occur due to poor business management and for non-compliance of its operation, has generated complaints and demands on public bodies inspecting, for these companies to regularize. This work is to present the General Purpose Activity Potential Impacts Reseller LPG and its Importance of Environmental Licensing. To this end, it was necessary to systematize the legislation concerning the Licensing Activity Relating to Resale of LPG; organize information about the Licensing orientative the Institute for Sustainable Development and Environment of Rio Grande do Norte - IDEMA; Identify the Current Situation in the State of Resellers , in Regularization on the Environmental Agency and the Potential Environmental Impacts. Become important to know the procedure of environmental licensing of this activity, as well as its potential, especially those related to the operation phase.
