Otimização de solução extrativa e desenvolvimento tecnológico de produto seco por aspersão de Psidium guajava L.

The increasing in the consumption of plant medicine by parts of the population generated a bigger need for studies. Drug substitutions, changes and adulterations at the production techniques are common places at plant-originated drugs trade, leading governmental departments of drug control round the world to adopt many analytical practices to medicinal plants. However, agronomic and technological issues cause characteristics and chemical composition variation at the drug, problem to be solved by the subject researchers. The present work aims to obtain a spray dried extract from a extractive solution obtained from Psidium guajava L. leaves based in book references that stress the intermediate dosage forms advantages. It also tries to validate useful methodologies for the quality control for both raw material and its derivates. Using eight sets of the spray dried extract (with Eudragit®, Aerosil ® e Avicel PH101 ® as drying adjuvants), the study proposes analytical methods using techniques commonly performed to plant medicines and its intermediate forms. As results, a viable spray-dried extract was obtained from a standartized extract solution. Among the studied adjuvants, the combination Aerosil ® with Eudragit ® showed the drying outcome, rheology, humidity and tannin content values that best fitted the demands of the Brazilian Pharmacopaea

Dos atos confessos aos afetos não-ditos: Um olhar sob as múltiplas experiências femininas a partir da análise dos discursos jurídicos, jornalísticos e orais

Women, subjectiveness, experimentations. This paper walks through gender, sexuality, body and subjectivity, bounding as the focus denaturalize the representations of womanlinessstaff and manliness and the modeled subjectivity by normative discusses that shows the transcendency based on multiplicities of experiences, wishes and life way wattled by men and women from the Caicó City s society in the decades from 1900 to 1945. For this, it was adopted a dialogic methodology inlcluding bibliographic and theorist references as well as sources like articles from Jornal das Moças (Lady s Journal); defloration s crime processes, abortion, infanticide and body lesions; iconographic sources and Caicó citizen memories in the period commented. Based on that sources, this work analyze the discursive construction of feminine through Justice and Jornal das Moças that paved by sanitarian, normalizing and moralizing discourses has spread clichés and stereotypes of womanlinessstaff and manliness, which has resulted by to universalize the experiences feminines in polarities and binary oppositions regarding to manliness, it has delineated them as asexual, irrational, anesthesiaed for pleasure and biologically meant to home activities modeling subjectivities that did not create ways for the singularization processes. This polarities, effects of sexual regulatory practices and gender legitimate the representations of courtship, maternity and honor, that although it has been incorporated not passivant on the building of the poor men and women subjectivity, it did not support itself in view of socio-cultural and economic reality of the poorest society side. Therefore, on this work emerge a plurality of women who has transited past the public sphere, who interlaced amorous informal relationships, who has kept relationships before the marriage, who hás established multiples familiar arrangements and helpful networks, who was single mothers without being considered dishonored women by social groups, who made matrimonial agreements without the rules of a formal civil marriage, who made use of beverageey to provoke the menstruation constituting multiples ways to experiment the life. This subjective feminine experimentations turned it possible to notice that representations concerning about the body, sexuality, date, maternity and honor of this women has constituted itself while molecularies and particulares . It was the affection not commented of the feminine sexuality that turned it possible to analyze the construction of singular subjectivities as a opened process, continuous, active, begetting new lands, life ways and wishes cartographies

A festa do bom Jesus dos navegantes em propriá-se: história de fé, espaço das relações sociais e laços culturais

The study is a survey conducted for the Master of Social Sciences carried out in partnership between the Universidade Tiradentes-UNIT/SE and the Universidade Federal do Rio Grande do Norte (UFRN). Being a religious event, we seek to show that the religious parties generally have particular meanings for each nation or region. Amaral (1998) informs that the Brazilian parties regardless of where they occur are popular demonstrations that, as the context in which they present themselves, can dilute to crystallize, to celebrate, to ritualize or sacralize the particular social experience of the groups that do. They happen as a way to thank victories or important religious passages as Christmas, the June saints celebration, patron saints and patron saints considered. Thus, The Bom Jesus dos Navegantes party in Propriá-SE: story of faith, a space of social relations and cultural ties, is presented as our field of study because it is one of those celebrations that while celebrated in Sergipe, always on Sundays in January, by some municipalities situated along the river San Francisco, has the characteristic of overlap any others placed in town, including the one of the city's patron saint, Saint Anthony, held on June 13. Concerning the materials and methods, we opted for qualitative research and participant direct observation, using the techniques of personal notes, interviews, newspapers, websites, photos, videos and testimonials from participants and organizers, as well as references offered by experts of the area. With this research answers were sought to questions about what could keep alive the celebration of Bom Jesus dos Navegantes each year in order that this is a patron saint, not saint; the way as the investment of local government with more resources in this period, during the organization of arts festivals, has created a thread of tension with the Catholic Church promoting the religious rituals was reviewed. It was also analyzed how the sacred and profane spaces present themselves inseparable from the celebration and, finally, it was revealed that the party retains its value by preserving its tradition and making room for modernity, not weakening but suffering metamorphoses of time and space and can be seen in the social and cultural bonds wrapped by the time of religious faith

Entre saberes e práticas :a alfabetização de jovens e adultos no MOVA Belém

This research analyses the experience of the Alphabetization of Young and Adults Movement named Prof. Paulo Freire (MOVA Belém) in the time period 2001-2004. the study intends to reveal which knowledge/activities are constituent of pedagogical practices of popular alfhabetzers. It also intends to contribute with the registry in the history of alphabetization of young and adults in Belém, without any intention of making general the analyzed aspects. The research is characterized by the use of a qualitative approach of the type ethnographic, because it involves an analysis that considers at the same time the local and global aspects. It analysis documents produced in the period and uses semi-structured interviews for data construction. It tries to show living cues and experiences of the pedagogical activities found in the theoretical references of Brandão (2003), Freire (1979; 1987; 1992), Gadotti (1998; 2000), Ribeiro (1999; 2003), Santos (1995; 2000), Soares (1985; 1998; 2003) and other authors of alphabetization and popular education fields. This multiplicity of bibliographical and empirical references has produced a heterogeneous framework, that is much more complex and multifaceted than the one which would be constituted as the knowledge of the pedagogical, alphabetizer practice. It can not happen, however, an absolute concept that is clear and total that resumes significance and matter of the pedagogical, alphabetization practice of young and adults. So, the study establishes a relativism between them assuming as valid the ones that are of popular and democratic types. At last but not least, it intended to contribute to the history of the alphabetization of youngsters and adults in Belém with a popular education perspective without any pretension to turn the analyzed aspects into generalized ones

A presença da produção científica em psicologia na formação de psicólogos do Rio Grande do Norte

The present research aimed to analyze the presence of national scientific production in undergraduate studies in Psychology of Rio Grande do Norte. Therefore, the bibliographical references contained in education plan of subjects linked to the common center of the courses, which were taught in 2011 in three Psychology courses of the state, were focused. The analysis of the material was based on bibliographical and contextual aspects of the production, such as year, nationality, type of material, authorship (including the link of authors to PPGs), structuring axis of the subject in which it was mentioned, among others. The results showed that the national production is predominant in all courses, and they are, mostly, originated from PPGs of Psychology. Among these, the publications resulted from programs in Southwest, with emphasis to PUC-SP, are recent (mostly from 2000s) and they are predominantly composed by books (organizations and full texts). Regarding the distribution of Psychology PPGs production by the structuring axes, it is observed that it surpasses the foreign production only in axis C (procedures of scientific investigation and professional practice) and axis F (professional practices). Accordingly, it is concluded that Psychology production is found in graduation, sharing space with foreign publications and from other areas of knowledge. On the one hand, this is positive, by taking into account the importance of several foreign works and from other fields to build the knowledge in Psychology; on the other hand, it shows that the production from this area is inserted in graduation in a less significant way than its growth, which points out the existence of gaps in the development of some investigative domains from national Psychology

Corpo, movimento e aprendizagem na psicocinética de Jean Le Boulch

School teachers in the discipline of Physical Education, we find ourselves constantly in question of methodological and epistemological issues of practice. This research aims to identify human body understanding, movement and theoretical learning proposed by examining the work of Jean Le Boulch and his approach to Physical Education. We seek to indicate epistemological elements about Physical Education theory and practice, believing that this approach and dialog comes to contribute with this field of knowledge. Boulch, a French teacher of Physical Education, Medicine and Psychology, had an important influence in Brazilian Physical Education during the 1970s and 1980s. His main contribution was teaching courses and knowledge about psychomotricity. Boulch’s studies helped to build knowledge of human movement; considering his importance in people’s development and a critic to a mechanistic view of body and movement. Our reflections will be based on the concepts brought from psychokinetics presented in the bibliographic references of Le Boulch in Brazil, and other references developed by him in this country including conferences, lectures and interviews. This reflection includes the debaters of his work. We chose a theoretical approach referring to the Phenomenology of philosopher Maurice Merleau-Ponty (1999) as a methodological reference considering the influence of his thought in Le Boulch studies. This thesis examines the learning and practice of teaching the Physical Education field of knowledge. We conclude that the body being an entity that exists for itself in the world and that contact with the world starts from human movement. Ultimately, new trains of thought for the teaching of physical education can be set from the reflection of phenomenological concepts brought by Le Boulch in his theory.

O ciclo Slopiewnie opus 46 bis de Karol Szymanowski: uma abordagem de estudo e performance

This text presents a discussion about the song cycle Slopiewnie Opus 46 bis of Karol Szymanowski, one of the most important Polish composers of the 20th century. Slopiewnie was composed on texts of Julian Tuwim, poet born in 1894 in Łódź, who used ancient roots to create new words and search for special sonorities. First, this text introduces a brief biographical sketch about Szymanowski, in order to contextualize Slopiewnie in relation to the composer’s works. Afterwards, the text provides an analysis of the songs and their texts, which may serve as a study tool for future perfomers. Interpretative suggestions are offered, based on the experience of learning these songs and on references. The text also presents the phonetic transcription of the poems, as well as a suggested translation to Portuguese, making it easier for Brazilian singers to learn the cycle’s text and prosody.

UBS RN-7: proposta arquitetônica para um padrão flexível de unidade básica de saúde para a zona bioclimática 7 do RN, com ênfase na sustentabilidade ambiental

Standardization and sustainability: these two apparently antagonistic words find the challenge of uniting in a flexible architectonic proposal. This was the idea that motivated the proposal of this assignment, whose appearing is bound up with the necessity of thinking about standardized spaces that attend on functional criterias and environmental sustainability, in reply to an existing real demand. The assignment consists of an architectonic proposal for a flexible standard of a Basic Unit of Health for the bioclimatic zone 7 of RN (UBS RN-7), with emphasis in the environmental sustainability. The project contemplates innumerable involved variables, such as: obedience to the current law of the Health Ministry for the UBSs; formal/aesthetic aspects; criterias of expansiveness of the UBS I for the UBS II; relative aspects to the constructive rationality and, mainly, sustainability aspects. With the intention to unite the variables and, also, glimpsing a proposal that could reach a good functional performance, aesthetic, of environment comfort and energetic efficiency, it was also necessary to consider concepts about the flexibility of the envelopment. The elaboration of the architecture first draft was based on bibliographical research, conceptual studies and references, elaboration of the architectonic program and the draft development for the UBS port I and the UBS port II. To the end, an implantation data sheet for the project is proposed for the UBS standard project, where strategies of thermal isolation, shadowing and thermal inertia are adopted and combined to three possible types of lot, resulting in 24 possibilities of implantation

Análise estatística de impedância da pele

In this work we analyze the skin bioimpedance statistical distribution. We focus on the study of two distinct samples: the statistics of impedance of several points in the skin of a single individual and the statistics over a population (many individuals) but in a single skin point. The impedance data was obtained from the literature (Pearson, 2007). Using the Shapiro-Wilk test and the assymmetry test we conclude that the impedance of a population is better described by an assymetric and non-normal distribution. On the other side, the data concerning the individual impedance seems to follow a normal distribution. We have performed a goodnes of fitting test and the better distribution to fit the data of a population is the log-normal distribution. It is interesting to note that our result for skin impedance is in simtony with body impedance from the literature of electrical engeneering. Our results have an impact over the statistical planning and modelling of skin impedance experiments. Special attention we should drive to the treatment of outliers in this kind of dataset. The results of this work are important in the general discussion of low impedance of points of acupuncture and also in the problem of skin biopotentials used in equipments like the Electrodermal Screen Tests.

Impactos da certificação ISO 9000 no desempenho estratégico :um estudo em empresas brasileiras do setor químico

This thesis deals with analyzing the contribution grade of the ISO 9000 quality system to the strategic performance of the Brazilian firms in the Chemistry sector, using the Balanced Scorecard system as reference. An exploratory research is developed to get technical information about these two management systems, with emphasis in their integration. After, a quantitative research is implemented using a questionnaire, to know and to obtain necessaries data for improving statistical estimations of the multiple relationships between the variables and the strategic performance for the universe of 352 Brazilians firms that make use of ISO 9000 as quality system. The size of the sample totalized 111 firms, which represent more than 31% of the selected universe. The main results show different visions of directors and managers about the significant variables that contribute for the strategic performance of the analyzed firms. The ISO 9000 system presents a big contribution to the strategic performance, when referred by the four perspectives of the Balanced Scorecard: learning and growth; internal process; customer and financial. Better performance was verified in the learning and growth perspective and reasonable performance was verified in the financial perspective

Metodologia estatística na solução do problema do caixeiro viajante e na avaliação de algoritmos : um estudo aplicado à transgenética computacional

The problems of combinatory optimization have involved a large number of researchers in search of approximative solutions for them, since it is generally accepted that they are unsolvable in polynomial time. Initially, these solutions were focused on heuristics. Currently, metaheuristics are used more for this task, especially those based on evolutionary algorithms. The two main contributions of this work are: the creation of what is called an -Operon- heuristic, for the construction of the information chains necessary for the implementation of transgenetic (evolutionary) algorithms, mainly using statistical methodology - the Cluster Analysis and the Principal Component Analysis; and the utilization of statistical analyses that are adequate for the evaluation of the performance of the algorithms that are developed to solve these problems. The aim of the Operon is to construct good quality dynamic information chains to promote an -intelligent- search in the space of solutions. The Traveling Salesman Problem (TSP) is intended for applications based on a transgenetic algorithmic known as ProtoG. A strategy is also proposed for the renovation of part of the chromosome population indicated by adopting a minimum limit in the coefficient of variation of the adequation function of the individuals, with calculations based on the population. Statistical methodology is used for the evaluation of the performance of four algorithms, as follows: the proposed ProtoG, two memetic algorithms and a Simulated Annealing algorithm. Three performance analyses of these algorithms are proposed. The first is accomplished through the Logistic Regression, based on the probability of finding an optimal solution for a TSP instance by the algorithm being tested. The second is accomplished through Survival Analysis, based on a probability of the time observed for its execution until an optimal solution is achieved. The third is accomplished by means of a non-parametric Analysis of Variance, considering the Percent Error of the Solution (PES) obtained by the percentage in which the solution found exceeds the best solution available in the literature. Six experiments have been conducted applied to sixty-one instances of Euclidean TSP with sizes of up to 1,655 cities. The first two experiments deal with the adjustments of four parameters used in the ProtoG algorithm in an attempt to improve its performance. The last four have been undertaken to evaluate the performance of the ProtoG in comparison to the three algorithms adopted. For these sixty-one instances, it has been concluded on the grounds of statistical tests that there is evidence that the ProtoG performs better than these three algorithms in fifty instances. In addition, for the thirty-six instances considered in the last three trials in which the performance of the algorithms was evaluated through PES, it was observed that the PES average obtained with the ProtoG was less than 1% in almost half of these instances, having reached the greatest average for one instance of 1,173 cities, with an PES average equal to 3.52%. Therefore, the ProtoG can be considered a competitive algorithm for solving the TSP, since it is not rare in the literature find PESs averages greater than 10% to be reported for instances of this size.

Análise estatística das emissões de CO e HC produzidas por gases da exaustão veicular oriundos de gasolina, GNV e mistura álcool/gasolina

The vehicles are the main mobile sources of carbon monoxide (CO) and unburned hydrocarbons (HC) released into the atmosphere. In the last years the increment of the fleet of vehicles in the municipal district of Natal-RN it is contributing to the increase of the emissions of those pollutants. The study consisted of a statistical analysis of the emissions of CO and HC of a composed sample for 384 vehicles with mechanization Gasoline/CNG or Alcohol/Gasoline/CNG of the municipal district of Natal-RN. The tests were accomplished in vehicles submitted to Vehicular Safety's Inspection, in the facilities of INSPETRANS, Organism of Vehicular Inspection. An partial gases analyzer allowed to measure, for each vehicle, the levels of CO and HC in two conditions of rotation of the motor (900 and 2500 rpm). The statistical analysis accomplished through the STATISTICA software revealed a sensitive reduction in the efficiency of the converters catalytic after 6 years of use with emission average it is of 0,78% of CO and 156 (ppm) of HC, Which represents approximately 4 (four) times the amount of CO and the double of HC in comparison with the newest vehicles. The result of a Student s t-test, suggests strongly that the average of the emissions of HC (152 ppm), at 900 rpm, is 40% larger than at 2500 rpm, for the motor without load. This result reveals that the efficiency of the catalytic conversion is limited kinetically in low engine speeds. The Study also ends that when comparing the emissions of CO and HC considering the influence of the fuels, it was verified that although the emissions of CO starting from CNG are 62% smaller than arising from the gasoline, there are not significant differences among the emissions of HC originating from of CNG and of the gasoline. In synthesis, the results place the current criteria of vehicular inspection, for exhaust gases, in doubt, leading the creation of emission limits of pollutant more rigorous, because the efficiency of the converters catalytic is sensibly reduced starting from 6 years of use. It is also raised the possibility of modifications in the test conditions adopted by the current norms, specifically in the speed engine, have seen that in the condition without load the largest emission indexes were registered in slow march. That fact that allows to suggest the dismissal of the tests in high speed engine, reducing the time of inspection in half and generating economy of fuel

Referências culturais e heterogeneidade discursiva :Uma proposta para o ensino-aprendizagem de língua inglesa

The purpose of this research is to approach the English literary text from the point of view of the culture and the heterogeneity of discourse in its role as a source of elements that facilitate the teaching/learning process of English as a foreign language. Several instances of discourse heterogeneity are analyzed through cultural references in the original texts of the following English novels: Jane Eyre, by Charlotte Brontë (1816-1855), published in 1847; The Mill on the Floss, by George Eliot (1819-1890), published in 1860 and Great Expectations, by Charles Dickens (1812-1870), published between 1860 and 1861. Theoretical support was sought in Kramsch, Bakhtin, Maingueneau, Authier-Revuz, Widdowson and Larsen-Freeman. Activities in English are proposed in the end whereby it can be seen that the questions at issue can be used extensively in the classroom.

Medidas e análise estatística em sinais bioelétricos sobre pontos de acupuntura

In the 20th century, the acupuncture has spread on occident as a complementary practice of heath care. This fact has motivated the international scientific community to invest in research that seek to understand why acupuncture works. In this work we compare statistically volt age fluctuation of bioelectric signals caught on the skin at an acupuncture point (IG 4) another nearby on acupuncture point. The acquisition of these signals was performed utilizing an electronic interface with a computer, which was based on an instrumentation amplifier designed with adequate specifications to this end. On the collected signals from a sample of 30 volunteers we have calculated major statistics and submitted them to pairing t-test with significance leveI a = O, 05. We have estimated to bioelectric signals the following parameters: standard deviation, asymmetry and curtose. Moreover, we have calculated the self-correlation function matched by on exponential curve we have observed that the signal decays more rapidly from a non-acupoint then from an acupoint. This fact is an indicative of the existence of information in the acupoint

Análise estatística de padrões sísmicos: decomposição em multiescala

O processamento de registros sísmicos é uma tarefa muito importante dentro da Geofísica e que representa um desafio permanente na exploração de petróleo. Embora esses sinais forneçam uma imagem adequada da estrutura geológica do subsolo, eles são contaminados por ruídos e, o ground roll é a componente principal. Este fato exige um esforço grande para o desenvolvimento de metodologias para filtragem, Dentro desse contexto, este trabalho tem como objetivo apresentar um método de remoção do ruído ground roll fazendo uso de ferramentas da Física Estatística. No método, a Análise em Ondeletas é combinada com a Transformada de Karhunen-Loève para a remoção em uma região bem localizada. O processo de filtragem começa com a Decomposição em Multiescala. Essa técnica permite uma representação em tempo-escala fazendo uso das ondeletas discretas implementadas a filtros de reconstrução perfeita. O padrão sísmico original fica representado em multipadrões: um por escala. Assim, pode-se atenuar o ground roll como uma operação cirúrgica em cada escala, somente na região onde sua presença é forte, permitindo preservar o máximo de informações relevantes. A atenuação é realizada pela definição de um fator de atenuação Af. Sua escolha é feita pelo comportamento dos modos de energia da Transformada de Karhunen-Loève. O ponto correspondendo a um mínimo de energia do primeiro modo é identificado como um fator de atenuação ótimo
