Representações discentes sobre a afetividade nas aulas de inglês de uma escola técnica

This work has risen from the researcher s pedagogical practice at a technical school in Natal, and it aims to observ how affectiveness is noticed by the students in their English classes, since we can have an idea of technicist teaching, which foccus on the acquisition of technical abilities. As cognition and affectiveness are considered indivisible elements in this research, we tried to identify the linguistic signs that express the students representations about affectiveness in their English classes. We used the Systemic Functional Linguistics approach to study the Ideational metafunction of Halliday (1994), by means of the transitivity system, to show how the clauses are used to illustrate these representations, and the interpersonal metafunction, that deals with the relationship between the teacher and the students. We tried to identify the most common processes (HALLIDAY, 1994) mentioned by the 68 students who participated in this work. We used learning narratives (BARCELOS, 2006) submitted to Wordsmith Tools computing program (SCOTT, 2009), whose results indicate the most frequent lexical items found in their narratives. The lexical choices seem to indicate that affectiveness is noticed as a composing element of the English classes in that school. There are representations of interacting classes, where the students needs are considered. These representations are built in the relationship of the students and the teacher, and they are grammatically realized by means of the polarity adjunct no , the intensity adjunct very , and the nominal group the teacher . The relational and mental processes (be) and (like) are the most used in their narratives, and we also observe that affectiveness and disponibility to help the students are considered the most important attitudes in their representations. The Appraisal system is used to analise the choices related to the attitudes and judgement of the students, that show appreciation for interacting classes, but there is still authorithary berhavior from the teacher in the English classes

Na trilha do poético: um caso de angústia da influência

Diese These besteht aus der Analyse der Enteignungsverhältnisse und der Misselung, welche in den Texten der Ursprung des Kunstwerkes und die Hymnen Hölderlins vorkommen. Germanien und der Rhein sind in den 30en-Jahren letzten Jahrhunderts von Martin Heidegger verfasst worden. Ab anwendung der kritischen Methodologia von Harold Bloom und der starken Texgestaltung von Richard Rorty wird es deutlich, dass die Heideggers Lesungen der Hölderlins Poesia als ei Ersatzversuch der von Hegel entwickelte Kulturgeschichte ab deutescher Überlieferung klassicher Studien, die das tragische Erlebnis der alten Griechen als grundlegender Punkt des Westen Daseins vorbringen, verstanden werden können. So verlegt Heidegger die Aufbauachse der Entstehungserzälung des Abendlandes in Richtung Dichtkunst, indem er in seiner Wendung zum Dichterischen gleichzeitig auf der Suche nach einer abweichenden Feststellung der vorherrschaftlichen These ist, in welcher die Tragödie das grosse Antrittsereignis der westlichen Zivilisation darstellt, und darüber hinaus noch der Herstellung einer innigen Verbindung zwischen der Poesie von Hölderlin und Hesiudus, um die Enge der dichterischen Überinstimmung zu zeigen, welche die alten Griechen und die zeitegemässigen Deutschen verbrände. Dieser geistige Aufbau Heideggers hat man somit als ein überholungsversuch Hegels Einfluss und Denkungsart zur Vollendung der von Nietzsche begonnenen Überwindungsaufgabe des Hegelianismus´zu verstehen

A moral kantiana entre deontologia e teleologia

This dissertation examines the Kantian moral in a teleological perspective. It consists of a reconstruction of philosophy practice that departs from the investigation of the categorical imperative, the concepts of duty, will, good will, as well as an approach on the ways of investigation of nature, which will enable the foundation to engage in the teleological argument, investigating the organized human beings, the harmonious system, its relationship with the ultimate and most important purpose, always flexing the analysis of these concepts the idea of purpose. Subsequently we will establish an argument about the end terminal and the implication of this concept to think about the real idea of the system in Kant and his relationship or support for moral theory. In essence this paper approaches the moral point of view of ethics, outlining the insufficiency of this field for the foundation of architectural moral, which will enable the final touch or the indispensability or the teleological argument as fundamental to the Kantian moral Theory

Determinacão do período orbital de sistemas binários clipsantes

In this work is presented a new method for the determination of the orbital period (Porb) of eclipsing binary systems based on the wavelet technique. This method is applied on 18 eclipsing binary systems detected by the CoRoT (Convection Rotation and planetary transits) satellite. The periods obtained by wavelet were compared with those obtained by the conventional methods: box Fitting (EEBLS) for detached and semi-detached eclipsing binaries; and polynomial methods (ANOVA) for contact binary systems. Comparing the phase diagrams obtained by the different techniques the wavelet method determine better Porb compared with EEBLS. In the case of contact binary systems the wavelet method shows most of the times better results than the ANOVA method but when the number of data per orbital cicle is small ANOVA gives more accurate results. Thus, the wavelet technique seems to be a great tool for the analysis of data with the quality and precision given by CoRoT and the incoming photometric missions.

Análise sísmica usando transformada de Curvelet

Oil prospecting is one of most complex and important features of oil industry Direct prospecting methods like drilling well logs are very expensive, in consequence indirect methods are preferred. Among the indirect prospecting techniques the seismic imaging is a relevant method. Seismic method is based on artificial seismic waves that are generated, go through the geologic medium suffering diffraction and reflexion and return to the surface where they are recorded and analyzed to construct seismograms. However, the seismogram contains not only actual geologic information, but also noise, and one of the main components of the noise is the ground roll. Noise attenuation is essential for a good geologic interpretation of the seismogram. It is common to study seismograms by using time-frequency transformations that map the seismic signal into a frequency space where it is easier to remove or attenuate noise. After that, data is reconstructed in the original space in such a way that geologic structures are shown in more detail. In addition, the curvelet transform is a new and effective spectral transformation that have been used in the analysis of complex data. In this work, we employ the curvelet transform to represent geologic data using basis functions that are directional in space. This particular basis can represent more effectively two dimensional objects with contours and lines. The curvelet analysis maps real space into frequencies scales and angular sectors in such way that we can distinguish in detail the sub-spaces where is the noise and remove the coefficients corresponding to the undesired data. In this work we develop and apply the denoising analysis to remove the ground roll of seismograms. We apply this technique to a artificial seismogram and to a real one. In both cases we obtain a good noise attenuation

Desempenho de pacientes com acidente vascular encefalico em testes de reconhecimento de tividades de vida diaria com frequencia autocontrolada e pre- determinada Luciana Protásio de Melo Natal 2009

The stimulation of motor learning is an important component to a rehabilitation and type of practice used is de basic importance to Physiotherapy. The motor skills are the types more basic of behavior that subjects must acquire throughout its lives and observational learning one of forms for its acquisition. Objective: This study aimed to compare performance of patients post- stroke on test of recognition of activities of day life using self-controlled and externally determined practice. Intervention: Forty subjects had been evaluated, 20 stroke patients (the mean age was 57,9?}6,7 years, schooling 6,7?}3,09 years and time of injury 23,4?}17,2 months) and 20 health subjects (the mean age 55,4?}5,9 years and schooling 8?}3,7 years). All was evaluated about independence functional (FIM) and cognitive state (MMSE), and patients were also evaluated about neurologic state (NIHSS). Later, all realized a recognition of activities of day life test (drink water and speak to telephone) on self-controlled (PAUTO and CAUTO) and externally determined (P20 and C20) frequency. The stroke subjects also were examined for a three-dimensional system of kinematic analysis, when they have drink water. The statistic analysis was realized for chi-square and t Student tests. Results: This was not difference, about number of rightness, between groups of self-controlled and externally determined practice (p0,005), and also not between patients and control groups (p0,005). Patients mean velocity (PAUTO: 141,1mm/sec and P20: 141,6mm/sec) and peak velocity (PAUTO: 652,1mm/sec and P20: 598,6mm/sec) were reduced, as well as the angles reached for elbow (PAUTO: 66,60 and 124,40; P20: 66,30 and 128,50 extension e flexion respectively) regarding literature. Conclusions: The performance on recognition of activities of day life test was similar between on self-controlled and externally determined frequency, showing both technique may be used to stimulate motor learning on chronic patients after stroke

Efeitos do treinamento aeróbio sobre sinais precoces do remodelamento do ventrículo esquerdo induzido pelo diabetes Mellitus experimental

Our aim was to investigate the effects of an aerobic training program on adverse and early left ventricle (LV) remodeling, using an experimental model of short-term type 1 diabetes (T1D). Wistar rats were divided in 4 groups: sedentary control (SC), trained control (TC), sedentary diabetic (SD) and trained diabetic (TD). T1D was induced by streptozotocin (45 mg/kg). The training program consisted of 4 weeks running on a treadmill (13 m/min, 60 min/day, 5 days/week). At the end of the experiments, hearts were collected for analysis of morphology and transcriptional profile of LV, by focusing on its remodeling. Deaths were recorded during the 4-week period. We verified high mortality among animals of DS group, whereas it was significantly reduced in DT group. DS group also showed an increase in cross-sectional area of cardiomyocytes and fibrosis. TD group exhibited reduction in measures of cardiac trophism, but with respect to collagen content, it was similar to CS group. Analysis of gene expression related to cardiac remodeling revealed decreased expression of collagen I and III, as well as low expression of MMP-2 in DS group. TD group showed decreased levels of mRNA for MMP-9, and unchanged gene expression of MMP-2 when compared with the CS group. The expression of MMP-2 and TGF-1 were increased in CT group. The ratio between gene expression of collagen I and III was increased in the CT group and decreased in diabetic groups. These results establish early changes of the structure and transcriptional profile of LV myocardium. Moreover, they indicate that aerobic exercise training plays specific protection against mechanisms responsible for cardiac damage observed in T1D

A participação feminina no movimento estudantil secundarista como espaço de luta política (anos de 1980)

The history of women has been an important thematic in the field of Historiography in recent years. Many History scholars have discussed thematics related to genre, pointing out their relationship and conflicts. These new thematics are also the result of a series of changing in history that bring out new problems, subjects and approaches. Our aim in this work is to analise the experience of women militants inserted into the student secondarist movement (ME) in Rio Grande do Norte in the years of 1980 s. Discussing the concepts of History and Spaces, we try to analise the political spaces of ME through public and private spaces that make part of the student militant life, pointing out the conflicts faced during their standing into the movement. To a better understanding of the ME political overview, we set a summary to point out the reconstruction of the student entities reorganized after the military governments, as well as we picture a general picture of this women s insertion in history. We use the oral source as the main methodological resource to the development of our work

Avaliação microscópica dos fragmentos ósseos obtidos por diferentes métodos de osteotomia e de irrigação em aloenxertos irradiados e congelados de coelho

Oral and facial bone defects can undertake appearance, psychosocial well-being and stomathognatic function of its patients. Over the yerars several strategies for bone defect regeneration have arised to treat these pathologies, among them the use of frozen and irradiated bone allograft. Manipulation of bone grafts it s not determined yet, and several osteotomy alternatives can be observed. The present work evaluated with a microscope the bone fragments obtained from different osteotomy methods and irrigation on rings and blocks allografts irradiated and frozen at 80° negative in a rabbit model. The study is experimental in vitro and it sample was an adult male New Zealand rabbit. The animal was sacrificed to obtain long bones, that were submitted to freezing at 80º negative and irradiated with Cobalt- 60. Then the long bones were sectioned into 24 bone pieces, divided into 4 groups: G1 (n=06) osteotomy was performed with bur No. 6 forming rings with 5 mm thickness with high-speed handpiece with manual irrigation; G2 (n=06) osteotomy was performed with bur No. 6 forming rings with 5 mm thick with surgical motor with a manual irrigation rotation 1500 rpm; GA (n=06), osteotomy with trephine using manual irrigation with saline; and GB (n=06), osteotomy with trephine using saline from peristaltic pumps of surgical motor. Five bone pieces of each group were prepared for analysis on light microscopy (LM) and one on electronic scan electronic microscopy (SEM). On the SEM analysis edges surface, presence of microcracks and Smear Layer were evaluated. Analyzing osteotomy technics on SEM was observed: increased presence of microcracks cutting with high speed; increased presence of areas covered by Smear Layer when cutting with motor implant. The irrigation analysis with SEM was observed: that the presence of microcracks does not depend on the type of irrigation; on manual irrigation, there was greater discrepancy between the cutting lines. The descriptive analysis of the osteotomy and irrigation process on LM showed: histological analysis showing the bony margins with clear tissue changed layer, composed of blackened tissue of charred appearance near to the cortical bone; on the edges of the bony part, bone fragments that were displaced during the bone cut and bone irregularities were observed. After analysis of results we can conclude: that there was greater regularity of the bone cut using high-speed handpiece than using motor implant; the cut with trephine using saline irrigated from peristaltic pumps of surgical motor showed greater homogeneity when compared with manual irrigation; charred tissue was found in all obtained bone samples, whit no significant statistically difference on the proportion of carbonization of the two analysed technics

Cisto dentígero: estudo epidemiológico, correlação clinicopatológica e caracterização de uma possível variante inflamatória

The aim of this study was to evaluate the clinical and pathological features of cases diagnosed as dentigerous cyst by the Department of Oral Pathology, School of Dentristy at the Federal University of Rio grande do Norte, attempting the possible correlation between histomorphological findings and epidemiological data contained at the files of the patients, in order to define a suggested variation of lesion named inflammatory dentigerous cyst. It was verified that dentigerous cyst are more frequently present in the earfy three decades of life, with the majority of cases occuring in the second decade (40,740/0 ), and also male (57,41%) and white patients (68,52%) were most affected. In relation to anatomic site, the dentigerous cyst was more prevalent at anterior maxila and posterior mandible, showing, usually, a slow growth pattem. The majority of lesions were asymptomatic and the radiographic observed was frequently na unilocular radiolucency. In regard to the histomorphological analysis, it was noticed that the lesions showed commonly a thin epithelium, with a capsule of fibrous connective tissue, richly vascularized and collagenized with an intense mononuclear inflammatory infiltrate. Finally, clinicopathological was performed and it was find out that cysts that showed a thick epithelium, with a high degree of vascularization and collagenization, intense inflammatory infiltrate in the cystic capsule, were located in the pre-molares region, in patients under 12 years old and the majority showing painfull sintomatology, properly, compatible with inflammatory dentigerous cyst. The findings of the present study indicate that, probably, there is a variant of the dentigerous cyst, and therefore, we suggest the denomination inflammatory follicular cyst for this entity

Estudo das propriedades psicométricas da escala WHOQOLold em idosos da região Nordeste

The population aging process increases the number of elderly people worldwide. In Brazil, a country of continental size, this process began in the 40s and happens with specific features in each of the different region s realities. This way, this thesis aimed to evaluate the psychometric properties of a elderly s quality of life (QOL) scale, the WHOQOL-old, in a population of the Northeast of Brazil. We sought to investigate the congruence between the content covered by the scale and the ones deemed as relevant by the participants. It aimed also study the validity evidences of the instrument s internal structure. To achieve the research objectives we adopted the design of multiple methods. The research was organized in two studies. For data collection, both studies used a sociodemographic questionnaire to obtain a profile of the participants and the Mini Mental State Exam (MMSE), used as exclusion criterion. A number of 18 elderly residents of the cities of Natal-RN and Campina Grande-PB, mean age of 73.3 years (SD = 5.9) took part od the study, They were organized into three focal groups (FG) in witch they discussed about the concept of QOL, what enhance and what hinders QOL. For Study II, a quantitative approach, 335 elderly from Campina Grande responded scale WHOQOL-old. They are between 65 and 99 years (M = 74.17, SD = 6.5). The FG data were analyzed by categorical thematic content. For the data analysis of the WHOQOL-old scale were used exploratory factor analysis and calculation of the Akaike and Bayesian information criteria. The results of both studies were triangulated. According to the discussions in the FG, health and social participation have central roles in quality of life. Social participation is related to all the other QOL s influences raised. The participants indicated the relevance of religiosity and were divided about the importance of sexual activity. Exploratory factor analysis (EFA) extracted a model of six factors. Two items (OLD_3 and OLD_9), not loaded on any factor and were excluded. The other items had factor loadings > 0.3. The response categories were reduced from five to three. After the scale changes, the empirical model showed better fit (-2loglikelihood = 8993.90, BIC and AIC = 9183.90 = 9546.24) than the theoretical model (-2loglikelihood = 18390.88, AIC = 18678.88 and BIC = 19228.11). Despite the best information criterion values, the RMESA remained above the ideal (0.06). We conclude that the WHOQOL-old presents psychometric parameters below the ideal when used with the Northeast population, but the improvements made the scale s use acceptable. The WHOQOL-old uses observable variables that matches with the participants' perceptions on quality of life. However, new strategies must be tested for a better sacale refinement

Avaliação termoanalítica da eficiência de antioxidantes na estabilidade oxidativa do biodiesel de mamona

The biodiesel is defined as the mono-alkyl ester derived from long-chain fatty acids, from renewable sources such as vegetable oils or animal fat, whose use is associated with the replacement of fossil fuels in diesel engine cycle. The biodiesel is susceptible to oxidation when exposed to air and this process of oxidation affects the quality of fuel, mainly due to long periods of storage. Because of this, the oxidation stability has been the focus of numerous researches since it directly affects the producers, distributors and users of fuel. One of the possibilities to increase the resistance of biodiesel is the autoxidation treatment with inhibitors of oxidation. The antioxidants can be used as potential inhibitors of the effects of oxidation on the kinematic viscosity and the index of acidity of biodiesel, thereby increasing oxidative stability. This work aims to examine the efficiency of antioxidants, α-tocopherol and butylated hydroxy-toluene (BHT), added the biodiesel content of remembrance through Pressurized-Differential Scanning Calorimetry (P-DSC), Thermogravimetry (TG) and Petrology. The results showed that the use of antioxidant BHT, at the concentration of 2000ppm, increased resistance to oxidation of the biodiesel and oxidative induction time (OIT), which is a better result as antioxidant than the α-tocopherol. With the thermogravimetric analysis, it was observed that the biodiesel presented an initial decomposition temperature of lower tendency than that of oil, demonstrating to be more volatile, bearing great similarity to the diesel and being characterized as an alternative fuel. The rheological analysis indicated that each sample of biodiesel behaved as a Newtonian fluid
