Fachada flexível para casa padronizada em condomínios

The employment of flexibility in the design of façades makes them adaptable to adverse weather conditions, resulting in both minimization of environmental discomfort and improvement of energy efficiency. The present study highlights the potential of flexible façades as a resource to reduce rigidity and form repetition, which are usually employed in condominiums of standardized houses; as such, the work presented herein contributes to field of study of architectural projects strategies for adapting and integrating buildings within the local climate context. Two façade options were designed using as reference the bionics and the kinetics, as well as their applications to architectural constructions. This resulted in two lightweight and dynamic structures, which cater to constraints of comfort through combinations of movements, which control the impact of solar radiation and of cooling in the environment. The efficacy and technical functionality of the façades were tested with comfort analysis and graphic computation software, as well as with physical models. Thus, the current research contributes to the improvement of architectural solutions aimed at using passive energy strategies in order to offer both better quality for the users and for the sustainability of the planet

Avaliação da espécie vegetal Croton cajucara Benth como inibidor de biocorrosão em aço carbono Aisi 1020

Actually in the oil industry biotechnological approaches represent a challenge. In that, attention to metal structures affected by electrochemical corrosive processes, as well as by the interference of microorganisms (biocorrosion) which affect the kinetics of the environment / metal interface. Regarding to economical and environmental impacts reduction let to the use of natural products as an alternative to toxic synthetic inhibitors. This study aims the employment of green chemistry by evaluating the stem bark extracts (EHC, hydroalcoholic extract) and leaves (ECF, chloroform extract) of plant species Croton cajucara Benth as a corrosion inhibitor. In addition the effectiveness of corrosion inhibition of bioactive trans-clerodane dehydrocrotonin (DCTN) isolated from the stem bark of this Croton was also evaluated. For this purpose, carbon steel AISI 1020 was immersed in saline media (3,5 % NaCl) in the presence and absence of a microorganism recovered from a pipeline oil sample. Corrosion inhibition efficiency and its mechanisms were investigated by linear sweep voltammetry and electrochemical impedance. Culture-dependent and molecular biology techniques were used to characterize and identify bacterial species present in oil samples. The tested natural products EHC, ECF and DCTN (DMSO as solvent) in abiotic environment presented respectively, corrosion inhibition efficiencies of 57.6% (500 ppm), 86.1% (500 ppm) and 54.5% (62.5 ppm). Adsorption phenomena showed that EHC best fit Frumkin isotherm and ECF to Temkin isotherm. EHC extract (250 ppm) dissolved in a polar microemulsion system (MES-EHC) showed significant maximum inhibition efficiency (93.8%) fitting Langmuir isotherm. In the presence of the isolated Pseudomonas sp, EHC and ECF were able to form eco-compatible organic films with anti-corrosive properties

Programa nova semente em perspectiva (2009-2012): uma avaliação de processo

Historically the provision of childcare facilities in Brazil was short of demand. This problem affects a large part of the population and has a tendency to worsen, due to the accelerated decline in the number of parents of dedication exclusive family. The program called "Nova Semente" seeks to accelerate the creation of childcare facilities in the county, enabling the opening of units at low cost and in record time, through partnerships between government, non-governmental and civil society organizations. This study conducted a process evaluation of the implementation of public policy, to identify the strengths and weaknesses of the policy. In real terms, this paper seeks to understand the motivation for the development of the program, identifying the reasons set out in the project match what is being sent; Understand how it is giving practical partnership between the government entity and the entities "non-state"; Identify the degree of achievement of goals that should be met even in the implementation phase; verify employment of instruments provided for its implementation.

Nacionalização do trabalho e constituição: análise das regras de nacionalização do trabalho à luz do princípio da isonomia

There is a clear relationship between citizenship and labor market. While foreign nationals are equal in dignity and rights in the laws governing the employment of this labor force. Motivated by reasons of state security or political direction, such laws to a greater or lesser degree, create establish a system of worker protection in the face of the foreign national. These rules have a direct impact on economic regulation, as they can affect the supply of skilled labor or not, articulating with the economic order envisaged by the 1988 Constitution. The Constitution adopts several principles in its economic order, so that the issues involving the rules of the nationalization of all work must be considered in a systematic way, one can not choose a pleasure interpreter. The nationalization of the work rules are not unique to Brazil, similar rules exist in several countries of South America and Africa. In Europe they already existed, but lost out on the basis of treaties setting up the European Union, although other mechanisms are used for the purpose of protecting the citizens of the member states, making policies equal treatment legislation symbolic. The nationalization of the work rules governing the relationship between nationality and the labor market and are in a legal category, which has a function to fulfill in the Brazilian legal system. Not all rules nationalization violate the principle of equality, as it is possible, depending on the circumstance indeed adopt a criterion that implies differentiation between nationals and foreigners. The Constitution has a will arising from its normative force, so that the assumptions it (constitution) used to discriminate may also be possible by ordinary legislation, since the situation is actually justifiably constitutional

O Cariri cearense: da ocupação do território à institucionalização da região metropolitana do Cariri

Urbanization in their mearing simpler, the agglomeration of people, occurred from the time that the productive activities have to be based on trade. The first cities arose when the evolution of agriculture allowed the production and storage of surpluses. However, with industrialization was that urbanization becomes intense, according to Singer (1987), the industrial revolution was to stage, from the beginning, the urban area. It requires, in its proximity, the presence of a large number of workers. With respect to the Cariri cearense, the occupation of its territory is associated with the movement of agricultural surpluses produced and reproduced under the hegemony of merchant capital and due to the development of extensive cattle that promoted the territorial occupation of Ceará. From the 1960s, the region has undergone changes in its productive structure due to industrial planning policies of the government of Ceará. However it was in the 1990s that the region itself as economic and urban polo because policies to attract investments from the state government of Ceará. This policy led to boosting trade and services marking the predominance of tertiary activities in the region, especially the retail, wholesale , medical services and education. Investments also consolidated the industrial park area making it diverse, especially the footwear industries, mining, non-metallic minerals, transport equipment, pharmaceutical chemical, food and beverages, rubber and leather and construction. Thus, the aim of this study was to review the region of Cariri cearense occupation of its territory institutionalizing its metropolitan region, to understand what factors influenced the Cariri cearense become an important area in urban and economic terms in the interior of Ceará. In order to develop this research in that refers to the methodological perspective, research is guided by bibliographic studies and also makes use of secondary data analysis (population, GDP, urbanization rate, employment) of the main databases the country, as IBGE, IPEADATA and RAIS - MTE

Ideais formativos de homem da emissora de Educação Rural de Caicó (Rio Grande do Norte, 1963-1978)

Under the aegis of the third diocese bishop of Caicó, Dom Manuel Tavares de Araújo, the Broadcasting Station of Rural Education of that city was founded, in May 1 s" 1963 with the ideal of being then an educational city, preferentially for youths and adults, rural meu and women of the arca of Seridó in Rio Grande do Norte state. In the year of its 40th birthday (2003), we began the investigation of that radio station choosing as study object its educational and formative programming, in the inc1usion of the first fifteen years of its existence (1963-1978), period that reaches the official inauguration of the Radio Station and the end of the bishopric of its fOllllder as Bishop of Caicó. Elucidating and showing Man's formative ideaIs longed by that Catholic educational broadcasting station, underlying to its radiophonic programming, such as the idealization for it reached, is the objective of this Doctorate work. It was considered pertinent to discover the guidelines that historically have permeated the Social Doçtrine of the Catholic Church addressing its aggiornamento, especially in what concerns to the employment of the modern ways of communication for the distance with the aim of evangelizing and educating. In arder to understand the ideaIs of the investigated educational Radio, we have delimited the research to the thematic Catholic Church, means of social communication and base education. In face of the study object and the aim to be reached it was appealed, methodologically, to the notion of cultural action present in Certeau (1995), and to the understanding of educational formation backgrounded fIam the modern thinkers that discuss it. Such frame references have allowed us to analyze in a wider spectrum tl)e programming broadcasted on the air by the sound wavys of that educ(itional Çatholic Radio, as well as, the very acts of cultural idealizations that has orientated it in its foundations. The thesis here defended is that. the Radio, at procJaiming itself as a broadcasting station of rural education directed preferably to the rural sertanejo countrymen, without neglecting its admitted ends, has surpassed them in its overall range. It was identified an articulate approach of its programmatic modules with the guid,elines emanateq from the Catholic Teaching about the use of the. means of social communication. At conceiving, establishin,g and executing an ec1ectic programmatic and div,ersified grating, the Rural Radio of Caicó has transcended to a strict human-Christian formation to request the development of the human, spiritual and cQrporaldimensions, jointly. With suchprogramming, it addressed to the seridoenses as real meu and women inserted in the "sertanej.o" environment with effective structural and existential problems of alI types, induding the hunger, the thirst, the syndical organization, the cQoperativism, the colIective modero work and the absence of universalizing school education. Its radiophonic transmissions, I}lled by the demands of an enlarged, open, dialogic and responsible communication, wheneIllbracing dedicated modules to religious and catechetical emissions, to the entertainment, to the radiojoumalism, to the country root culture, and to the school education of b se for the modality of the School and of the radiophonic classes, subsumed to ideaIs that longed for the formation of a multifaceted and pluridimensional sertanejo Man; of men and women that, without abjuring the Catholicism, were able to understand, to dialogued and to live together with the general demands of a society in progressive mutation, whose economical, social, cultural and educational demands it IDade themselves to be felt through the sertão potiguar of the Serido region, equal way of the intemationalized world

A utilização do controle estatístico do processo para o monitoramento do sangue: estudo de caso no Memonorte-RN

The present work is grounded basically on the use of the Basic Tools for the Statistic Process Control SPC, with the intent to detect non-conformities on a given productive process. It consists on a case study accomplished at a Hemocenter in Natal (Rio Grande do Norte). In this study it is shown that, the Statistic Process Control Technique, which was used as a tool, is useful to identify on-conformities on the volume of hemocomponents. The gathering of the used data was performed by means of document analysis, direct observations and database queries. The results achieved from the study show that the analyzed products, even though when they have presented, in some cases, points out of control, they satisfied the ANVISA standards. Finally, suggestions for further improvement of the final product and guidance for future employment of CEP, also extended to other lines of production, are presented

Algoritmos genéticos aplicados a um comitê de LS-SVM em problemas de classificação

The pattern classification is one of the machine learning subareas that has the most outstanding. Among the various approaches to solve pattern classification problems, the Support Vector Machines (SVM) receive great emphasis, due to its ease of use and good generalization performance. The Least Squares formulation of SVM (LS-SVM) finds the solution by solving a set of linear equations instead of quadratic programming implemented in SVM. The LS-SVMs provide some free parameters that have to be correctly chosen to achieve satisfactory results in a given task. Despite the LS-SVMs having high performance, lots of tools have been developed to improve them, mainly the development of new classifying methods and the employment of ensembles, in other words, a combination of several classifiers. In this work, our proposal is to use an ensemble and a Genetic Algorithm (GA), search algorithm based on the evolution of species, to enhance the LSSVM classification. In the construction of this ensemble, we use a random selection of attributes of the original problem, which it splits the original problem into smaller ones where each classifier will act. So, we apply a genetic algorithm to find effective values of the LS-SVM parameters and also to find a weight vector, measuring the importance of each machine in the final classification. Finally, the final classification is obtained by a linear combination of the decision values of the LS-SVMs with the weight vector. We used several classification problems, taken as benchmarks to evaluate the performance of the algorithm and compared the results with other classifiers

Estudo das propriedades físico-químicas de biocombustíveis microemulsionados

The development of new fuels is an important field of scientific and technological activities, since much of the energy consumed in the world is obtained from oil, coal and natural gas, and these sources are limited and not renewable. Recently it has assessed the employment of microemulsions as an alternative for obtaining fuel isotropic between phases originally not miscible. Among many advantages, emphasizes the application of substances that provide the reduction of levels of emissions compared to fossil fuels. Thus, this work was a study of various microemulsified systems, aiming to check the performance of the winsor regions front of the use of surfactants: RENEX 18 → 150, UNITOL L-60 → L-100 and AMIDA 60, together with structure of esters from soybean and castor bean oils. From the results it were chosen four systems to physico-chemical analyzes: System I RENEX 60, Soil bean oil, methylic ester (EMOS) and water; System II RENEX 60/AMIDA 60, EMOS and water; System III RENEX 70, mamona oil methylic ester (EMOM) and water and System IV RENEX 95, EMOM and water. The tests of physico-chemical characterization and study of temperature increase were done with nine points with different compositions in a way to include the interest area (microemulsion W/O). After this study, was conducted a modeling to predict the viscosity, the property is more varied as function of compositions systems changes. The best results were the systems II and IV with a temperature stability above 60°C. The system I had its physico-chemical characterization very similar to a fossil fuel. The system II was the best one due to its corrosivity be stable. In the modeling the four systems had shown good, with an error that varied between 5 and 18%, showing to be possible the viscosity prediction from the composition of the system. The effects the microemulsion and the engine´s performance with the microemulsion were also avaliated. The tests were performed in a cycle-diesel engine. The potency and consumption were analysed. Results show a slight increase the rendiment fuel compared with the conventional as well as a decrease in specific consumption

A gestão da qualidade nos cursos de graduação a distância da UFRN/SEDIS : a percepção dos discentes

The management of water resources in the river basin level, as it defines the Law nº 9433/97, requires the effective knowledge of the processes of hydrological basin, resulting from studies based on consistent series of hydrological data that reflect the characteristics of the basin. In this context, the objective of this work was to develop the modeling of catchment basin of the river Jundiaí - RN and carry out the study of attenuation of a flood of the dam Tabatinga, by means of a monitoring project of hydrological data and climatology of the basin, with a view to promoting the development of research activities by applying methodologies unified and appropriate for the assessment of hydrological studies in the transition region of the semiarid and the forest zone on the coast of Rio Grande do Norte. For the study of the hydrological characteristics of the basin was conducted the automatic design of the basin of the river Jundiaí, with the aid of programs of geoprocessing, was adopted a hydrological model daily, the NRCS, which is a model determined and concentrated. For the use of this model was necessary to determine some parameters that are used in this model, as the Curve Number. Having in mind that this is the first study that is being conducted in the basin with the employment of this model, it was made sensitivity analysis of the results of this model from the adoption of different values of CN, situated within a range appropriate to the conditions of use, occupation and the nature of the soil of this basin. As the objective of this study was also developing a simulation model of the operation of the Tabatinga dam and with this flood control caused in the city of Macaíba, it was developed a mathematical model of fluid balance, developed to be used in Microsoft Excel. The simulation was conducted in two phases: the first step was promoted the water balance daily that allowed the analysis of the sensitivity of the model in relation to the volume of waiting, as well as the determination of the period of greatest discharges daily averages. From this point, it was assumed for the second stage, which was in the determination of the hydrograph of discharges effluent slots, that was determined by means of the fluid balance time, on the basis of the discharges effluents generated by a mathematical equation whose parameters were adjusted according to the hydrograph daily. Through the analyzes it was realized that the dam Tabatinga only has how to carry out the attenuation of floods through the regularization of the volume of waiting, with this there is a loss of approximately 56.5% on storage capacity of this dam, because for causing the attenuation effect of filled the shell of this dam has to remain more than 5m below the level of the sill, representing at least 50.582.927m3. The results obtained with the modeling represents a first step in the direction of improving the level of hydrological information about the behavior of the basins of the semiarid. In order to monitor quantitatively the hydrographic basin of the river Jundiaí will be necessary to install a rain gauge register, next to the Tabatinga dam and a pressure transducer, for regular measurements of flow in the reservoir of the dam. The climatological data will be collected in full automatic weather station installed in Agricultural School Jundiaí

Jornalismo e narrativas transmidias: a reportagem no contexto da convergência

The transmedia storytelling is a phenomenom recently conceptualized theoretically (JENKINS, 2009), arising from ficcional mediatic products and disseminated as well by the use on other fields. This search aims to analyze how the transmedia storytellings can be applied to journalism on the basis of an specific genre, the reporting. To that, take as reference theoretical developments performed by brazilian authors (FECHINE et al., 2011, 2012, 2013), on the basis of televisive fiction, which culminated on concepts as transmediation and transmedia contents and deepened the comprehension and the research in this area. Thenceforth, this study propone a problematization and apropriation of this theoretic support for the journalism field, using, for that, a comprehension of journalistic production on a speech level, as well as its social practices (newsmaking). The empiric research also take two different paths. First, analyze a group of reportings, in which there is transmediation, in order to verifying the configuration of the transmedia phenomenom - more specifically of the transmedia storytelling - and its particularities to journalism. Then, develops an investigation, based on the etnographic method, of the productive routine on the special reporting section of the Jornal do Commercio (Recife/PE), aiming to investigate the conditions of transmediation in this range and the practices that favor and difficult the employment of transmedia storytelling. The result are, therefore, compared and related, with the goal of providing multidimensional view of the phenomenom

caracterização in situ e estrutura genética de populações de Gossypium mustelinum

Gossypium mustelinum Miers ex Watt is the only cotton species native from Brazil. It is endemic of the semi-arid region from North-east of the country, where it occur near from resilient water sources. The threats to the in situ conservation of the populations are caused by human interference in its habitat, mainly by excessive cattle graze and deforestation. Establish efficient strategies of in situ conservation depend on the accomplishment of a diagnosis of how the specie is found in its natural environment, and the knowledge about the genetic structure of the populations. The objectives of this work were i) to determine the in situ conditions of two populations present in rivers from basin of Rio Paraguaçu at the Bahia State, ii) to evaluate the structure and genetic variability presented in both populations, iii) to establish in situ and ex situ conservation strategies. It were realized collection in november 2007, when was realized in situ characterization of G. mustelinum. SSR markers were used for analyze 218 genotypes deriving from two populations of the G. mustelinum, localized at Tocó river and the Capivara river. The allelic frequencies, the heterozigosity and the F statics were estimated. All the plants were classified as wild and natives, and there was no evidence of the use the plants or its parts. The populations showed different conservation conditions in situ. Few plantlets were found in sites with excessive cattle feed, an indication that the damages in young plants should be high enough to compromise the renovation of the populations. On the other hand, populations were well preserved when the anthropic damages was low or inexistent. The 14 SSR primer pairs amplified 17 loci with a medium number of 5 alleles per locus (a total of 85 alleles). The high level of endogamy estimated (FIS=0,808) and the low observed heterozygosity (H0=0,093) were indicatives that the populations reproduce mainly by selfing, geitonogamy and crosses between related individuals. The genetic diversity was high (HE=0,482) and the differentiation between the populations was very high (FST=0,328). At least two sites from both populations of G. mustelinum must be preserved to achieve suitable in situ conservation. Actions that preserve the gallery forest and keep the cattle away should implemented, and could be as simple as erecting a fence. It is not possible anticipated if the in situ preservation will be possible. Therefore collections and ex situ preservation of representative specimens are essential to conserve the genetic diversity of native G. mustelinum

O programa Saúde da Família pelo olhar do Cirurgião-Dentista

This study tried to know the social representation of dentists surgeons about the Family Health Program (FHP). Where used as methodological instruments a semi-structured interview and direct observation of work process in tive towns that are part of the metropolis region ofNatal city. During the interview some aspects where broached, such as the reasons of dentists surgeons join the FHP, what are the implications ofthe introduction of this program in the everyday practice, what kind of activities are they practicing and what are those professional missing the most in the FHP. In the direct observation where take in account some aspects related to the physic structure of health units, its service organization and demand, relationship amongst dentist and other member of the team, and about patient receptiveness, when they arrives at health unit. This study also identifY the researches subject showing their age, sex, for how they are graduates, what are them specialty and for how long they work for the FHP. The data had been analyzed through the analysis of content of Bardin5. The dentists depict the FHP for the change in assistance model through the preventive proposal of social work that makes possible to work with an ample concept of health. However what makes the FHP more attractive to dentists is the salary questiono The creation of bonds whit the community and the work whit groups and in team had been the main occurred changes in the daily one of the pratices ones of these professionals. The principal activities executed for these professionals inside of the new strategy of assistance in oral health are the carried trough preventive activities achieved in health units and social area. To them, the absence of institutional support and the employment of only one dentist for each team it is one the main point of strangling. There is no doubt that FHP is new strategy and that it is need a better integration amongst the professional, the institution

Precarização do trabalho no setor de supermercados : um estudo de caso com trabalhadores em Natal

Precarization of work, process situated historically after the third Industrial Revolution, express itself as one of the faces of changes in production modus and working conditions. The present study aims to identify the process of work precarization in supermarket sector in Natal municipality. The choice for this sector and professional category is based on low investment in studies on the commercial sector and on technological and administrative transformations that supermarkets have implemented. After a bibliographical review, ten indicators of precarization were chosen which permitted to set up a schedule to interviews and its application to employees of two supermarkets (local companies) in Natal area. The following working functions were chosen to participate in the survey: cashier, display assistant (shelf-stacker) and attendants (N=6). From the interviews we developed an analysis of categorical contents in order to identify the presence of precarization indicators. Categorizations allowed us to identify five major themes: work categorization; work meaning: its attributes; work meaning: work centrality; comments on the employment of apprentices or trainees; and transversal work contents. Such themes contents express or not the presence of precarization process at supermarket sector in Natal area. Precarious work is identified in participants speech when they refer to the employees decreasing power in salaries negotiation between them and employers that institute the precarious work conditions

O programa de saúde da família e os princípios básicos do Sistema Único de Saúde na realidade de Santana do Matos RN

This work shows the professional staff of the Family Health Program (PSF) in Santana do Matos City perceive the Unified Health System (SUS). Their discourse and recognition of the advances of SUS, as well as their participation on the implementation of the system, are analyzed. The Brazilian Ministry of Health instituted it in 1994 in order to rebuild the health politics on a new basis, substituting the traditional model. The city-centered implementation of SUS was instituted on May 27, 1992 by the act nº 631/92 and today it experiences a Full Management of Basic Attention. In July 2001 the PSF program was started in the city with 5 teams: 2 in the urban zone and 3 in the rural one. The methodology was developed with the combination of qualitative and quantitative research with the employment of a questionnaire with both open and closed inquiries to 31 members of the program. The study appointed that, no matter how positive and enlarged be the staff s concept of health and SUS, they dont s have on understanding of the total chain of the system on its integrality, hierarchy and regionality what hinders the system performance close to the users. The PSF incorporates and reaffirms the basic principles of the SUS; however, on its everyday employment it has not yet abandoned totally the curative model, which is reinforced by the hospital-centered and physiscian-centerend culture
