Estudo sobre a influência do massará no processo de formação de salitre em rebocos na região de Teresina - PI

This work had to verify the influence of massará, while mortar component, in the process of formation of saltpeter in cementitious plaster walls of buildings. The massará is a ceramic material, texture areno usually found in large volumes argillaceous sediments in Teresina, Piaui State capital, which is associated with the Portland cement mortar form for fixing and finishing in construction. Saltpeter or flowering is a pathology that happens in gypsum wallboard, which invariably reaction between soluble salts present in materials, water and oxygen. This pathology, supposedly credited to massará caused its use to suffer significant reduction in the market of the buildings. Verify this situation with particular scientific rigor is part of the proposal of this work. Grading tests Were performed, consistency limits (LL, LP and IP), determination of potential hydrogen, capacity Exchange (CTC), electrical conductivity (EC), x-ray fluorescence (FRX) and x-ray diffraction (DRX). Massará analysed samples in number six, including sample plastering salitrado presented potential hydrogen medium 5.7 in water and 5.2 on KCl n and electrical conductivity (EC), equal to zero. These results pointed to the affirmative that massará is a material that does not provide salinity content that can be taken into consideration. It is therefore concluded that the material analyzed not competing, at least with respect to the presence of soluble salts, for the formation of saltpeter

Comportamento adaptativo de Lutzomyia longipalpis (Diptera: Psychodidae) às áreas urbanas da cidade de Teresina-PI.

The sand fly Lutzomyia longipalpis (Diptera: Psychodidae) is currently appointed as the main vector of visceral leishmaniasis in the Americas. The growth of cities in areas originally endemics to American Visceral Leishmaniasis (AVL) resulted in the spread of the disease at the same time that observed the adaptation of this species to the urban environment.Changes in behavior of L.longipalpis that enabled the adapt to increasing losings of biodiversity, as well as the frequent exposure of the vector to insecticides evident in urban areas, could justify the increasing population of the species and consequently the spread of disease for these environments .Thus, we selected sixty houses spread among three areas with increasing stages of occupation of an area endemic for AVL in Teresina-PI. We evaluated the correlation between the density of L.longipalpis captured and different aspects, such as population density of animals, vegetation cover and socio-economic aspects in each house. In addition to the correlations, the feeding preference of the vector between the predominant plant species in the neighborhoods, as well as the presence of metabolic mechanisms of resistance among the captured insects were tested. The results showed that over the growing occupations, represented by three areas, L.longipalpis demonstrate its adaptive nature through an apparent opportunistic behavior in relation to sources of carbohydrates and blood. On the evolutionary point of view, this behavior may have favored its vector competence in urban areas among the limited presence of food sources, as well as in various environments encountered.

Prevalência e fatores associados à sintomatologia dolorosa e a qualidade de vida de odontólogos da cidade de Teresina-PI

Objective: Identify the factors associated to the painful symptomatology and the quality of life and in dentists in the city of Teresina-PI. Brazil. Methods It was accomplished a cross-sectional study with 175 dentists registered with the Regional Council of Dentistry-PI from March to May, 2007. For characterization of the dentists we used a multidimensional questionnaire containing sociodemographic (age, sex) and professional information (time of service, journey to work). The evaluation of the presence of pain was performed by the Protocol of Painful Symptoms of McGILL. The WHOQOL-Bref was used to assess quality of life through physical, psychological, social and environmental domains. Results / Conclusions The painful symptomatology was reported in 69,7% of individuals, being observed in 77.3% of women and 60.3% of men. Body regions where pain was prevalent was the regions of neck (69,2%) lower back (69,7%). The dentists had high levels of self-perception of quality of life satisfaction and health. 96,0% of the individuals reported quality of life as very good, and only 16.6% reported dissatisfied with health. The Physical and Environmental domains showed values higher than the psychological and social domains. The painful symptomatology of studied dentists is associated with female sex (RP=1.28; IC95% 1.04-1.58; p<0.01). A multivariate analysis by logistic regression was performed and only the painful symptoms (OR = 2.51, IC95% 1,21-5,21) remained associated with the quality of life of these professionals when adjusted for other variables studied

O processo avaliativo institucional de desempenho do sistema público municipal de Teresina-PI (2001 a 2005): entre a lógica da excelência e a lógica da aprendizagem

This work focalize the institutional and educational evaluation, aiming to investigate the Municipal System Institutional Evaluation Performance of Teresina City Piauí (2001-2005), and to reflect about Institutional System Performance and its contribution to compose a new learning evaluation practice. In this sense, classifies elements about the evaluation practice in two Elementary Education municipal public schools, involving Education Municipal Bureau technicians as managers, pedagogues, teachers and students. Based on the ethnographic studies principles in the educational area, the work employs investigative procedures like document analysis, interviews with groups and individuals and also participator s comments. Intending to comprehend the complexity produced by the institutional and education evaluation processes, the wok reveals the Institutional Evaluation legal and educational political basis and the several positions assumed by the Learning Evaluation, as a classification tool or as a learning enhancement. This work points, as results, to a evaluation culture bipolarity carried out by the Municipal Education System as a explicit control and regulation toll, related to the classification and learning in a interaction process that operates both in the pressure and the reflection, as a culture practice established between excellence of logic and learning. The evaluation history has been construct on the evaluation actions dialectics, joint simultaneously between the Institutional Evaluation Performance and the learning evaluation. The senses, meanings and actions bipolarity is a interaction process product sustained between the institutional evaluation, under the scholar ranking application, and the learning evaluation. In this relativity, the teacher evaluation practice is found, ruled by interesting, thoughts and actions on the school evaluation, allowing a higher security and support to the learning results. Grounded in the researched reality, its possible to say that the teacher s evaluation practice is diversified, with different characteristics, when it is done in the learning search and in the learning intention. In the first case, reflects, rearranges and constructs new actions that lead the student to produce learning. In the second, shows the will, the wish of learning, but is a weak action, producing a not really significant learning and development; as a result, remains the mark approach as a determinant in the student future. The work s hope is to contribute not just to rethink these two evaluations dimensions the institutional and the learning ones but also to organize the school and to improve the pedagogic process

Gestão ambiental e competitividade: um estudo sobre os fatores que afetam a decisão de compra de produtos orgânicos na cidade de Teresina-PI

The organic products represent one of the main trends of alimentary consumption in the new century. In Brazil, the answer is already well representative which it becomes the country, as a great consuming and exporting market of products of LVF type. The objective of this research was to investigate the factors capable to influence the food consumer in its purchase decision of organic products in the supermarkets of Teresina, capital of Piauí State. The methodology was exploratory and descriptive, using survey, with closed and opened questions in 542 interviewed. The questionnaire was based on projected scales to evaluate the factors that can influence the purchase decision of organic products, whose variable had been grouped in the following groups: behavior, knowledge, interest, competitiveness, importance, barrier and profile. The used statistical techniques were descriptive analysis and multiple regression analysis. The results demonstrate interest of the population in paying more for the organic product, due to better quality of life, however it lacks to one better spreading and greater sensitization to attract these consumers. Some recommendations and proposals are presented after the results, as suggestions for future research

O uso da representação cartográfica e a cartofobia: analisando a prática e a formação inicial docente na Geografia do ensino público em Teresina-PI

This word has objective to analyzer the relevance of the use of the cartographic representations, in the constructions of the geographical knowledge, during the process of the teaching-learning in the classes of the Geographic of the High School, drawing liam with the formation docent of the regulars courses of teacher training in the regular courses of Degree in Geography. Delimit is the area of empiric search to College State Zacarias de Goes (CEZG) Liceu Piauiense, and to regulars courses of Degree in Geography of the University Federal of the Piauí (UFPI) and University State of the Piauí (UESPI), educational institutions of the public network, located in the city of the Teresina Piauí. Expression of the problematic searched is gaps to been demystified on the vision cartofógica, when has reference to use of the cartographic representations, in the practice, and the initial formation docent in the Geography. To analyze the dynamics of the use of the cartographic resources, tried demystify the Cartography while of the space during the teaching of discipline Geography. So, the lyam with the initial formation in the begree search understand the impasses of construction to academic know and the possibilities of the didactic transposition to the restructure of the know scholar to teacher who works in the Geography, trying to make the teaching of this discipline more interesting and value

Qualidade dos serviços hoteleiros: percepções dos turistas de negócios de Teresina-PI

Business tourism is one of tourist segments with different market characteristics in relation to others segmentations, such as low seasonality, there is no requirement of natural attractions, it serves as destination projection and it generates profitable larger numbers. Due to the context around business travels, the hotel so many times has a fundamental whole among the elements of the production chain in this segmentation. Business tourism in Teresina is the primary segmentation of the capital, since it represents almost 70% of hotel demand; hence this research has as objective to evaluate through the perceptions of business travelers, the level of quality services of hotels of Teresina. The research is exploratory and descriptive, of functionalist character. This study is characterized by qualitative and quantitative research, supported by a basis of methodological pluralism. For primary data collection was performed applying a suitable research instrument of SERVPERF model (Service Performance). The universe of this study were Teresina's accommodations, restricted to only those that fit in hotel category and it was inside metropolitan area of Teresina. The study subjects were business travelers who were hosted in these hotels. For the analysis, it was considered certain factors: descriptive analysis, factor analysis, correlation matrix analysis of the variables; It was still compiling a graphic of lexicons obtained in the survey about respondent's the notion of quality of vision in the hotel service; Finally, qualitative analysis was based on the theories of marketing, targeting and quality of tourism services applied. The results show that the Teresina hotel service is on a regular average, especially for Reliability and Safety dimensions were highlighted. Whereas, the factor analysis showed the emergence of two factors to explain "Empathy" dimension, one of this is about the organization and the other one is about consumer. And by Lexicometria was possible to observe the importance to the customer of other variables such as: personal aspects, price and location for this tour segmentation.

Vitalidade no centro antigo Teresina, Piauí Praça Marechal Deodoro: uma intervenção contemporânea em área de valor patrimonial

This study deals with the discussions of contemporary interventions in public spaces in areas of heritage value. The product of this dissertation is an Intervention Project to Marechal Deodoro Square located in Teresina/PI center. The starting point for understanding the theme of this study is to investigate the accessibility and vitality of a public space - through relationship between form and uses. The spatial properties of accessibility and visibility as well as the distribution of land use - factors were associated with distinct patterns of vitality - and compared to usage patterns observed in situ and statements from users obtained through the results of the questionnaires. In attention to questions about the building constructed, particularly in historical centers, considers the guidelines to define intervention strategies in the square, consisted in the development of simulations that after evaluation of results of redesign, was chosen the best option to meet the necessary requirements to the performance, considering the spatial properties of integration and visibility that meet these requirements. Therefore, the "Intervention Project" carried out for the Marechal Deodoro Square characterization proposed items are discussed: spatial structure, vegetation, road network, pavements, street furniture and lighting

Habitus docente e representação social do ensinar Geografia na Educação Básica de Teresina - Piauí

The literature about the Geography teaching has shown that most male and female teachers of this subject go on guiding their teaching practice based on the traditional Geography fundamentals, whose main characteristic consist in the description of places. The incorporation of scientific standards that change the old principles and concepts have not been happening, unless in a punctual way. The overcoming of the traditional Geography, related to the aspects accepted by the scientific field have not happened in Brazil yet, not only because of certain obvious obstacles, as the literature has been pointed out but also by symbolic obstacles, which block the incorporation of the new, of the non habitual action. One of those obstacles that motivated the accomplishment of this study was the social representations that are theoretically studied here under the perspective developed by Serge Moscovici. Then, the focus of this doctorate study is concentrated in the apprehension of the content and structure of the social representation of teaching of Geography and its relation with the habitus that gives form and social visibility to the ones who are teachers of that subject in Teresina. The consecution of this work was especially based on the Pierre Bourdieu´s praxiology, mainly on the concepts of social field, habitus and capital, as well as the theory of social representations, specifically on the approach of central nucleus developed by Jean-Claude Abric and Jean-Claude Flament. The initial hypothesis pointed out the existence of a Geographer´s primary habitus built through the development process of the geographic science field in Brazil, as a basis of production of a social representation of teaching geography . That representation, however, would act as a symbolic obstacle to the incorporation of the new scientific contents and pedagogical practice, which require from the teacher investigative and questionable attitude in the presence of the reality and contents approached in the classroom. That initial hypothesis laid on the theoretical purpose that it has been developed by Domingos Sobrinho (1997), which states that there is a narrow relationship between the habitus and social representation. The study was developed with male and female teachers of Geography from public schools of Teresina. The methodology involved the use of a questionnaire, the free-word association technique and deep interviews. The achieved results showed the presence of a complex process of representational construction and its articulation with a habitus produced by the synthesis of several situational and cultural referents, from among of them we can point out an insertion in a social field of practice exclusively related to the teaching and the reproduction of a professoral teaching (SILVA, 2003), built through the school development process, which those male and female teachers were exposed. The initial hypothesis that considered the local reproduction of a primary habitus of the Geography was denied, therefore, it was verified that there is not in Teresina the production/reproduction of the structures, rules and practice of the national scientific field, in which this subject is inserted. Hence, the incorporation of the new patterns of the geographic scientific knowledge is difficult because of the inexistence of a scientific habitus, that is, mental schema systems that would let the teachers mentioned above connect themselves appropriately to the science and its practices. So, it has gotten a social representation of teaching geography based on contents strictly related to the reproduction of structures, mental schema from the educational field which attach themselves to the hegemonic pedagogical practices in the national scope

A forma do privilégio: renda, acessibilidade e densidade em Natal-RN

The aim of this work is to understand the morphological expression of ground occupation by the higher income population, by focusing on population distribution in accordance with income layers and demographical density, as well as topological accessibility (HILLIER and HANSON, 1984) resulting from the urban grid structure. It endeavors to identify a functional organizing principle regarding the intra-urban space of Natal capital city of the state of Rio Grande do Norte, the research focus. In order to achieve this, census data as well as syntactic data were utilized for mapping and spatial analysis of income patterns, topological accessibility and demographical density using Geographical Information System GIS. The organizing principle was named as the Form of Privilege, a pattern that concentrates or tends to concentrate wealth, topological accessibility and low demographical density. Attempting to assess its extent, beyond Natal, this principle was applied to other Brazilian northeastern capitals such as: Fortaleza, CE; Teresina, PI; Aracaju, SE; Recife, PE; and João Pessoa, PB. Findings point out that although the urban structures of these cities are not immune to the Form of Privilege, Natal is emblematic of this phenomenon, a fact that demonstrates the perverse character of its spatial process, which historically creates privileged areas within the city, by means of the appropriation of accessibility as well as of the many urban benesses that are related to it by higher income groups at the expense of the major part of the population, which though being the people mostly in need of the benefits originating from the urban form are excluded from them

Efeito da adição de carbonatos em formulação de massa para revestimento cerâmico utilizando matérias-primas do Piauí

Piauí state is a major producer of traditional red ceramic burning as bricks, tiles and ceramic tiles, with its main production center located in the city of Teresina. The state has large reserves of raw materials that can be used in the ceramic coating as clays, quartz, talc and carbonates. However, in the preparation of ceramic bodies using only a mixture of clays with different characteristics. The study aims to evaluate the effect of adding two types of carbonates in the ceramic semiporous mass coating produced in Piauí and then to verify the potential use of these carbonates as supplementary raw material product manufactured or the feasibility of obtaining a ceramic plate that meets the specifications for the porous coating. For this, were characterized the ceramic Piauí coating mass, a calcitic carbonate and a dolomitic, were made in the levels of 2, 4, 8, 16, and 32%. The masses were formed by pressing and burneds in two environments: a laboratory furnace (1080°C, 1120°C, 1140°C, and 1160°C) and an industrial furnace (1140°C). Then, following tests of linear shrinkage water absorption, apparent porosity, bulk density and flexural strength. Furthermore, the fired specimens were tested for their macrostructure and microstructure. The results showed the possibility of using the carbonate in ceramic mass flooring produced in Piauí, as added in small proportions improved dimensional stability and increased mechanical strength of ceramics pieces. It also proved itself possible to produce porous coating when added in higher levels

Resistência da artéria carótida e autônima funcional em mulheres idosas

High carotid artery resistance indices in the elderly arise mainly as a result of harmful daily lifestyle behavior and poor eating habits. The aim of this multidisciplinary study was to assess and correlate carotid artery resistance and functional autonomy in elderly women. A descriptive, exploratory cross-sectional study was conducted with a sample comprising 27 women, enrolled in pastoral programs in the city of Teresina, Brazil. Carotid artery resistance was assessed by a high-resolution Doppler ultrasound device and functional autonomy was evaluated through five protocol tests of the Latin American Development Group for the Elderly (GDLAM), simulating activities of daily life. The data were analyzed by the Shapiro-Wilk test and the correlation by Spearman s test, considering a p-value of <0.05. The sample consisted of women with mean age and standard deviation of (68.67 ± 4.52) years, respectively and carotid resistance index of (0.71 ± 0.07). The general index value of functional autonomy classified the elderly of the study group as weak in the performance of activities of daily living (30.46 ± 6.31). The general index of functional autonomy showed a high level of sedentary behavior in the group studied (p < 0.01). The sample was classified as weak in the performance of activities of daily life. The correlation coefficient between the carotid resistance index and the general GDLAM index was r = 0.998 and p = 0.000, showing a significant correlation. The elderly women assessed had a high carotid artery resistance index and low functional autonomy; a positive correlation was found between the dependent variables studied. To perform this study we formed a team composed of a nurse, who helped in organizing the sample and performing the examinations; a radiologist, who conducted the Doppler examinations; an angiologist, who collaborated in interpreting examination data; in addition to two physical education professors and two physical therapists, who applied the functional autonomy tests and conducted the 34 research along elderly health lines, contributing thus to the multidisciplinary character, fundamental for carrying out the study

Tear identitário:a prática docente em arte como conhecimento compartilhado

This investigative tissue is about the formation of identification processes of teachers and pedagogical practice of Art, in Teresina city. This search comprised the sum of the needs presented, agreed upon with the teachers engaged in the process, it was developed through the establishment of interactive environment Loom Team where collaboration and critical reflection were steering actions to promote the understanding of existing connections or relations within the processes of identifications and the pedagogical practice of Art. The tissue is formed by the polyphonic plot of the critical reflection of nine teachers of Art who engaged voluntarily and this investigation of formative nature and a production of knowledge. All these teachers have degree and the course of artistic education and especial qualification in Fine Arts and/or Drawing. The texture, which we denominated Identification Loom: The pedagogical practice of Art as share knowledge is (de) (re) construction of knowledge resulting from the critical reflection, in an environment of collaboration, which may have implications and ethical political attitudes in the pedagogical practice of the group. Within this context, we pose the following question: - How does the pedagogical practice in Art influence and/or be influenced by the identification processes of the teachers, and how do they interfere with the search and manifestation of the knowledge involved and the investment in professionalization? In view of this query, we make use of the cooperative investigation, having social history as theoretical reference and as analytic perspective of interactive and dialogical-reflexive processes. Thus, social historic theory, cooperative approach and pedagogical practice were the major components of the plot. The methodological texture counted on the threads of dialogical reflexion, of mediation and of collaboration. The conceptual formulation, the recording in videos of classes and the narratives of formations were the main threads of the analytic substrate of the investigation. With this articulation, theses threads appear as developers of processes leading to a major approximation of the thought on the identity/alterity dialectical pair of the participants involved. The language within this plot had a decisive importance in all the moments of the search of signification, embracing and connecting the identification/alterative processes, the pedagogical practice of Art and the knowledge shared. In such processes involving (de) (re) construction, one can notice a close correlation of the triad social identity, pedagogical practice and knowledge shared. For this reason, the vigotskian, guetmanovian and kopnian theoretizations were the major framework for the analysis of conceptual formulations; and, as for discourse analysis, Baktin and Orlandi were our masters. For these teachers, the experience shared throughout the process of this typology of tri-axial investigation focused the experience of many theoretical and practical assumptions. Such an experience enabled them to state that this, with collaboration, can make reflection on the practice a starting and promoting element, within the individual level of self-management, in addition to being a space of (de)(re)construction of meanings, of knowledge and of reinvention per se
