Currently are consumed large quantities of materials for the construction of popular housing. Based on this situation, the work aims to produce ceramic blocks with the reject of crushed glass (resulting from the stoning in glassware). The glass powder was evaluated by laser granulometry, X-Ray Fluorescence and X-Ray Diffraction. The cylindrical specimens composed by cement, sand, gypsum, lime and ground waste glass were made. The glass waste underwent by sieving process, obtaining a glass powder thinner (160 µm), which provided a better mixing between the constituent elements of the composite. A practical use of the composite would be the production of lightest constructive block with greater thermal resistance and cheaper than those produced by conventional materials. From the characterization of these ceramic blocks obtained with the glass waste was achieved to identify the thermal comfort conditions and mechanical resistance. It is important to consider that the use of powder glass in the manufacture of blocks implies the reduction of glass waste, which probably would have been discarded in the environment.

Aiming to evaluate the effects of vegetables insecticides on Anastrepha spp. in orchard of guava, two researches in Barbalha were conducted, from may 6th to June 24th of 2011, testing Pironat ®, Rotenat ® and Natuneem ®. To evaluate the effect on adults, 20 McPhail traps baited with protein corn hydrolyzed at 5% were settled, evaluating the number of insects captured weekly. On the evaluation of the effect on larvae, we collected at random 100 fruits, cheking the presence of larvae alive and dead. Three applications were made of the products in both experiments with a motorized costal atomizer, with evaluations accomplished weekly. The Pyroligneous extract of Pironat® repels the adults of Anastrepha spp satisfactorily, while the azadirachtin present in Natuneem®, promotes insecticide effect on the larvae in the field conditions, which these products showed greater efficiency after the second application. Although these vegetable products don't causes 100% of control, they can be used in agroecological Anastrepha ssp. management in guava orchards, therefore are cheap, of easy application and don’t cause environmental impact in terms of risk of toxicant residues in the fruits.

Studies of the adsorption of heavy metals in soil can be used to assess this contribution in the contamination of surface and groundwater. This work had as objective to study the adequacy of the models of Langmuir and Freundlich to describe the adsorption of copper in a Rhodic Hapludox soil with clay texture. To determine the adsorption capacity of copper in the soil, we used 2.000 g of soil added 10 mL of CaCl2 0.01 mol L-1 and 10 mL solutions of CuCl2 with different concentrations. The maximum adsorption capacity of copper in the soil, determined by the Langmuir model, was 2.95 mg g-1. Moreover, the results showed that the Freundlich model showed better fit to the experimental data, adequately simulate the adsorption of copper in the soil under study.

This research aimed to investigate the scientific articles in the area of executive secretariat, through the of verbal processes, frequent verbal forms and patterns of use, to help students, researchers and professionals in training Executive Secretaries in producing scientific articles. As a theoretical basis, the Systemic Functional Linguistics (SFL) was used, which studies language in use in different contexts - was developed by Halliday (1985, 1994) and reviewed by Halliday and Matthiessen (2004), among others.. From this perspective, the research considers the ideational metafunction, based on verbal processes (i.e. say), as the analysis category. With regard to the scientific study of genres, the research is based on Bhatia (1993), Swales (1989, 1990), Swales & Feak (1999), Motta-Roth (1995, 2006) and others. The computational instrument WordSmith Tools 5.0 (Scott, 2009) was used to map on data starting by wordlisting and concordance, particular tools that allow patter identification. We studied 161 articles, in English, selected from three online magazines in the Executive Secretariat area, that area does not contain publications in Scielo yet. The results showed that the most frequent verbal processes were: mean, determine, highlight and affirm, and that the most frequent verb forms were: 3rd person singular, passive and infinitive. Furthermore, the identified patterns showed that some had no verbs function process and, speech high rates were reported.

The present study sought to investigate the interaction of the federal net of technical and technological teaching with their audiences, here defined as: newly servants; other schools; students and their parents; city halls; companies; philanthropic associations; NGOs; in other words, all and any entity that has interest in the participation in activities accomplished by those educational institutions. It was looked for with that, search if there is use of tools that facilitate that relationship and for which means this is made. This is a case study with predominantly qualitative approach, which allowed to conclude that the relationship of the federal net of technical teaching doesn't present a prepared organizational structure to communicate so much with the internal members and the social agents both. It is waited that this research awaking in the education managers the importance that the communication channels to represent for the satisfactory results.

This article aims to provide the reader an analysis on the relationship established between two different fields of studies, Gender Studies and Cultural Studies, which have been the basis of researches developed within the themes that have stimulated our studies and investigations, such as childhood, culture, consumption, gender, sexuality, beautification, production, and politics of bodies. To do so, we focus our discussion on the study of some discursive practices. After considering the importance assigned to these fields in educational researches linked to perspectives in poststructuralist analysis, as well as the way we deal with them, the intention is to discuss and question some of their features, emphasizing their productive relationship. In conclusion, it is necessary to mention their contributions to our investigations, which discuss the production of gender and cultural identities in contemporary childhood.

This study aimed to evaluate by means of laboratory tests, field tests and numerical simulations, of characterizing the natural and compacted soils used in landfill design and construction industry in the oil sector. For the construction of the landfill was necessary implementation of an experimental program to characterize the subsurface of the landfill site area from SPT and Geophysical testing, characterization of the three soils (Soil "1" Soil "2" Soil "3") used in the construction of the landfill, the evaluation of potential soil contamination by means of infiltration tests, evaluation of slope stability. The three soils analyzed were classified according to USCS as MH, GM and SC respectively. From the trials in the field of infiltration by the method of concentric cylinders was determined hydraulic conductivity of compacted soil that was approximately 10-7m/s. The strength parameters of soils were obtained by empirical correlations that related to cohesion and friction angle of soil with plasticity index of soils. As recommended by the NBR 11682/2009, we applied a factor of cohesion and the mitigation was thereafter performed slope stability analysis by method of Fellenius, Bishop and Janbu. The slope stability analysis by limit equilibrium methods, show the equilibrium analysis of slopes with safety factors calculated for various methods induces to the upper range minimum (FSmin = 1.5) for each method.

This research proposes using a technology without new wires for environments of Small Office and/or Home Office (SOHO), with a security view. Indeed digital information products are vital to the new economy. However, the small businesses which provide services to large companies, end up having access to that virtual heritage without any security requirement. The practical studies want introduce that the infrastructure of Information Technology for SOHO equipment can be achieved without new wires, through the electrical grid. This system will be demonstrated through practical results in different environments of the Power Line Technology study.

Activities on the farm are gaining prominence on the national stage when it comes to job security. Treating to meet their hazards is the first step to having based decision making and planning of these activities. Therefore, we will in this work, pointing out the possible dangers in the activity of the cultivation of papaya in Region Baraúna in the state of Rio Grande do Norte. For this, we used the tool known as APP (PRELIMINARY ANALYSIS OF DANGER) to qualify them by tables containing the activity performed, dangers, causes, detection mode, and effect, categories of frequency, severity, risk, and its recommendations and observations. The survey was conducted in papaya producing farms in the municipality of Baraúna, state of Rio Grande do Norte. The work was divided into stages lifting hazards, interviews with employees and visual observation of the work of these routines. The results indicate higher risks of accidents with hands and legs, having a better definition of scenarios and prioritization frameworks and guidelines for proper management of safety and health of employees involved in this activity.

The counterculture phenomenon, since the last century 1970s, has been the subject of several studies by social cientists, semiotic, poets and other scholars. The intense rebellion wave that marked the 1960s, 1970s and 1980s on the western world, is always discussed in a dichotomous approach related to bourgeois capitalist society model, whose racionality was despised and countered by "beats", "hippies" and "cool people" that swell the ranks of the conventionally called counterculture. This job addresses the couterculture another perspective and point to the possibility of understanding this phenomenon as a result of the dinamic of their owner culture, being part of the required deviant behavior that moves and transforms creatively scenarios by which cultures express themselves also as part of them. We support our reflection on authors such as Roszak (1972), Maciel (1985), Pereira (1985), Bauman (1988, 2012), among others.

Dimension stones are materials that add value through standard color, design, texture and grain. According to Mendes e Paiva (2002), Pernambuco is inserted in the Borborema Province of evolution marked by great tectonics mobility, alternating compressive and extensional regimes. In the region there were 3 distinct tectonic events, in which deposits of non-oriented rocks (granitoid) and moved rocks (orthogneisses and migmatites). Ten litho types were cataloged: Red Brown, Samba Red, Salmão Lagoa, Imperial Pink, Frevo Granite, moved rocks, and Sunset Red, Red Ventura, Red Ipanema, Yellow Ipanema, being the “Imperial Brown” the one that stands out most commercially, isotropic materials. The physical indices of seven of these materials suited to values determined by Frazão & Farjallat (1996), while the compressive strengths of four rocks are below this chart. Only one rock has lower flexural strength and other low resistance to trampling. The physical and mechanical properties of the rocks of Pernambuco, compared to those proposed by Frazão & Farjallat (1996) attest good quality materials and can be used on surfaces with high trafficability; high mechanical strength; low absorption and porosity indicate their suitability for wet locations noting, however the mineralogical composition.

In this work, the main chemical characteristics of asphalt binder oil residue were studied and compared to the properties of the corresponding asphalt binder. The Nuclear magnetic resonance and Fourier transform infrared spectroscopy spectra indicated the presence of aliphatic groups, aromatics, carbonyls and sulfoxides. The thermogravimetric curve showed that the residue begins its thermal decomposition at a higher temperature, probably due to lower content of maltenic fraction. Hydrocarbons polycyclic aromatics (HPAs) were extracted from the maltene fraction using chromatographic methods such as: matrix dispersion in solid phase, chromatographic adsorption in column and gas chromatographic. The results indicate that the materials present toxic HPAs, as well as, mutagenic and carcinogenic.

With this article we enter the field of Human Rights related to secondary education. Here we have an experience report concerning an extension project entitled “Continuing Education in Human Rights for Middle School Teachers” which was finalized this year. This aimed to introduce the theme of human rights in the educational field in Alagoas, Maceió more specifically, a city known problematic as it is the minimum guarantee of the rights of citizens who inhabit it. To this end, the project was developed within a public school high school and involved an in-service training for teachers of this level of basic education throughout the years of 2010 and part of 2011 (May). So in this article do three major approaches: the first deal of historical and political foundations of Human Rights Education in Brazil. On Monday, we discussed the project methodology and results, and the third: point out the challenges and possibilities for those facing the difficult task of dealing with this issue within the classroom of the school as “knowing” rather than “charity”.

This research seeks to contribute to the educational inclusion of people with visual impairments, proposing changes in the daily life of the classroom through the creation and production of low-cost resources to promote the learning of knowledge of physics 2nd year of high school. Discusses the importance of resources in the area of physics for students with visual impairments and how major contribution presents a set of features, designed and produced, with discretion, through the contribution and validation by students with visual impairments in the 2nd year of high school the State Schools, assisted by the Center for Educational Support Services for the Visually Impaired Persons of Maranhão - CAP-MA. The features designed refer to the contents of spherical lenses, aspheric optical behavior of the geometric and construction of images, showing also some tips for teachers to make the resource as productive as possible, through the interaction of students with sighted students with blindness or low vision. It is considered that this is a work of extensive social contribution, therefore, with resources designed and produced, Physics teachers can use them or taking them as a reference, streamline their classes, favoring the inclusion of students with disabilities visually.

The street fairs are dynamic spaces, essential for socio-economic integration between communities, especially in small towns. Among the products available are medicinal plants, important therapeutic resources for the poorest portion of the population. We aimed to determine the socioeconomic and cultural characteristics of the herbalist in Currais Novos/RN. The activity is predominantly practiced by men, low income and education. The trade of medicinal plants is the main source of income for 67.0% of the respondents and the data points tend to the extinction of the activity at the street fair of Currais Novos.

We present a theoretical study proposes an approach for easy understanding of the magnetic properties of rare-earth (TR) dysprosium (Dy) and holmium (Ho) from the electronic structure of these elements. The unpaired electrons in the 4f orbitals give rise magnetism of the TR, so that they present high values of magnetic moment compared to other chemicals. Nanomagnetic systems involving artificial nanolayers of Dy and Ho have been studied extensively in recent years, due mainly to the exotic magnetic phases presented by these materials, favoring, increasingly, the emergence of new magnetic properties in these systems, industries and interest of the magneto-electronic and magnetic refrigeration.
