O discurso formativo do Biólogo sobre a morte: matizes e metáforas do saber que o sujeito não deseja saber

This study - Biologist s formative speech about death. Nuances and metaphors from knowing that the subject of do not want to know - shows a marginal cognitive construction in scientific education from biologist - death. It considered as obvious that death is a theme that covers both the scientific education from biologist and the division of the subject, and concerns the splitting of the double life-death and the principles of inclusion and exclusion of the subject. Part of sensitive question: What is the epistemological weave who supports biologist's speech about death? It is constituted an object of study of the biologist s speech on death. It is advocated the thesis that: Death is an epistemological obstacle announcing for something always aims to escape from the perspective of knowledge, especially of scientific knowledge because, since it is understood as cognitive learning about the disruption of biological phenomenon life which is involved on weave of imaginary and symbolic constructions about the finiteness of life; it has constituted a metaphorical knowing - encouraged by the noisy silence - which does not allow to know in full, mobilizing hence subject in searching for transitional truths that reduce the ontological being-mortal anguish centered in subjective dimension involved in the act of knowing. From this movement of search that the object mental life after death wins a symbolic value that requires a real-looking multi-referential for the study of biology - life - and its implications: the finiteness of life, especially by moving the omnipotence of scientific objectivity expressed by signs and symbols that seek say the completeness of scientific knowledge-, signaling thus the existence of the dynamics of incompleteness implicit in subjectivity that supports knowledge relating to the double, life and death, and to the temporality of the existence of Homo sapiens sapiens, with the axis guiding the desire of the subject, do not want to know about death, implicit in the mechanisms objective-subjective founded by non-said of death is the epistemology of the existence of objective-subjective subject, whose core is the negation of death. The theoretical methodological knowing web is anchored in the multi-reference which favors a transit by theoretical current, as the Psychoanalysis, bachelardian philosophy, the epistemology of complexity, the Thanatology, the Social Psychology, and Etnocenology, and Understanding Interview. The unveiling of the study object from the analysis of oral speech of eleven biologists who serve in high school, from three main guiding: Death in the history of life,Death in biologist s academic education and, Conceptions about concepts

Para uma andragogia do esporte:discutindo as diretrizes e a formação profissional para a Educação Física de Jovens e Adultos

For the development of this research the following general objective has been formulated, indicator of the process of inquiry: To discuss the relation between the attitudinal and the sportive contents presented in the proposal of Curricular Lines for the Physical Education of Young and Adults in Brazil. According to the corporeity and the ludicity, questioning the formation of the professional of Physical Education and delineating the perspective for a sport andragogy that values the Being and the Life. From this general objective, the following objectives, which had given greater specificity to the investigative process, were defined: 1. To create the theoretical context from the corporeity/ludicity axis, articulating transversally sportive knowledge, aiming to contribute for a sport Andragogy; 2. To analyze the objectives proposed for the Physical Education of Young and Adults according to an elaborated theoretical reference and to the testimonies of the egresses of 2005 of the Physical Education course of the UFRN. 3. To interpret the relation between attitudinal and educative content from the academic reality lived by the egresses of the Physical Education course of the UFRN. 4. To understand the most urgent necessities of sustained formation of the egresses of 2005 for satisfactory performance with the Physical Education of Young and Adults. 5. To propose perspectives for the construction of a sport Andragogy from the corporeity/ludicity axis. In attendance to the nature of this research and as form of guiding ourselves in this epistemological adventure, the following ones had been basically and theoretically estimated. 1. Corporeity is a radiant focus, prime and main of educational criteria; 2. The task of the education must be carried through with men and not for men; 3. Man must only play with the beauty and with the beauty he only must play. ; 4. The sportive education must be based on esthetic and fair play. The adopted research approach is of a qualitative nature, using the interview procedure with a group consisting of twelve egresses of the Physical Education Course of the UFRN of the year of 2005.2 After the discussion of the results on the attitudinal objectives and content for the Physical Education for Adults and Young, the study shows nine themes presented by the investigated group as priorities for their sustained formation, aiming at the performance of the professional of Physical Education with the EJA: inclusive experiences; leisure and quality of life; relationships; body and personal care; social values; self esteem; sportive phenomenon; EJA training; attitudinal contents. As a contribution to the construction of knowledge for a Andragogy of Sports, the study presents a metaphorical structure called Galaxy of Knowledge righteous Glamor of integrating nine elements inspired by the Ode to the Sport of Pierre de Coubertin: life, beauty, justice, daring, honesty, joy; Fertility; progress; peace. At the heart of the structure of knowledge is righteous install a system that articulates five principles ludopoiético epistemological function of connecting with the righteous knowledge of the sport that must integrate the content attitudinal proposed for Fitness for Youth and Adults in order to facilitate the realization of their objectives proposed for this method of teaching

Itinerário educacional de uma aluna cega e a busca pela imagem adaptada

The scope of this study directs an investigation in search of how the blind person learns knowledge at school mediated by the image in context of an inclusive education and how it can be (or is) triggered by the adaptation of images to the tactile seizure of the blind person and his correlative process of reading. To achieve this intent we choose a qualitative approach of research and opted for the modality of case study, based on the empirical field of a public school in the city of Cruzeta, RN and as a the main subject a congenitally blind female student enrolled in high school there, focusing, often, on the discipline of geography in its words mapping. Our procedures for construction of data are directly involved to the documentary analysis of open reflective interview and observation. The base guiding theory of our assessments is located in the current understanding about the human psychological development of its educational process inside an inclusive perspective, of contemporary conceptions about the visual disability as well of image as a cultural product. Accordingly, the human person is a concrete subject, whose development is deeply marked by the culture, historically built by human society. This subject regardless of his specific features, grasping the world in an interactive and immediate way, internalising and producing culture. In this thinking, we believe that the blind person perceives in multiple senses the stimuli of his environment and acts in the world toward his integration into the social environment. The image as a product of culture, historically and socially determined, appears as a sign conventionally used as an icon that in itself concentrates knowledge of which the student who does not realize visually himself and his surroundings cannot be excluded. In this direction, the inclusive educational process must build conditions of access to knowledge for all students without distinction, including access to the interpretation of the images originally intended for the seizure strictly visual to other perceptive models. Based in this theory and adopting principles of content analysis, we circulated inside the interpretation of the data constructed from the analysis of documents, from the subject speeches, from records of the observation made in the classroom and other notes of the field daily. In the search for pictures on the school contents, adapted to the tactile seizure of blind student, was seen little and not systematic in practice and teaching at the school. It showed us the itinerary of the student life marked by a succession of supports, most of the time inappropriate and pioneers in cooling the construction of her autonomy. It also showed us the tensions and contradictions of a school environment, supposedly inclusive, that stumbles in search of its intent, in the attitudinal and cumulative barriers brought, because of its aggravating maintenance. These findings arose of crossing data around of a categorization that gives importance to 1) Concepts regarding the school inclusion, 2) Elements of the school organization, educational proposal and teaching practice, 3) Meaning of the visual image as the object of knowledge, 4) Perception in multiple senses and 5) Development and learning of the blind person before impositions of the social environment. In light of these findings we infer that it must be guaranteed to the disabled person removal of the attitudinal barriers that are against his full development and the construction of his autonomy. In that sense, should be given opportunity to the student with visual disability, similarly to all students, not only access to school, but also the dynamics of a school life efficient, that means the seizure of knowledge in all its modalities, including the imagery. To that end, there is a need of the continued training of teachers, construction of a support network in response to all needs of students, and the opportunity to development of reading skills beyond a perspective eminently focused in the sight

Entre o sol e a liberdade impera a violência: formação de redes para a ação a partir da estratégia saúde da família

The research aimed to analyze the feasibility of forming a network of municipal services to prevent and treat child victims of violence from the Basic Health Units in the Family Mossoró / RN. The research is a qualitative approach and was developed in the form of action research. The population was composed of representatives of institutions of the child and primary care professionals. Data were collected through questionnaires, workshops and semi-structured interview. The results were analyzed from data collected through the questionnaire designed to assess the material, lectures, dialogues and assessments with the team and presented in accordance with the findings of the research. The study was approved by the Ethics in Research UFRN with protocol No. 158/2010, CAAE: 0176.0.051.000-10. Situational diagnosis in the participants answered a questionnaire to characterize and then launched the guiding question of the focus group FHS While professional what your perception towards violence against children? It was felt the fear and ignorance on the part of the unit staff on how to prevent and to refer cases of violence against children and adolescents in the area of coverage of the unit and also realized that the professionals felt victims of occupational violence before the violence has reached proportions that the area of the unit. Mind the need to change strategies to work to combat violence, we plan to conduct focus group workshop to complete the questionnaire, training for protection against occupational violence, and meeting with other bodies responsible visor protecting children and adolescents to draw the flowchart of the victims in safety net. The next moment training to fill the notification form professionals were interested in learning and use this tool to combat violence. At the third meeting in Unity, meeting with representatives of the Child Protection Council, the professional unit showed interest in interacting with the agency to expose and combat violence against children and adolescents. Due to difficulties in the physical structure of the unit was not possible to continue the research and planned every moment, and then completed the data collection with interviews with the participating professionals, to assess the meetings. Therefore, it is considered that action research has also achieved its goals because the team was involved in the collective construction of a proposed change in the practices of referral and prevention of violence against children and adolescents. This involvement was favored using the principles Freirian during the course of the study. However, it is assumed that the network was not fully implemented because it is known that it is in a continual process of improvement and must continue evolving with the unit team.

Understanding the origin of photoluminescence in disordered Ca0.60Sr0.40WO4: An experimental and first-principles study

Visible photoluminescence (PL) was observed for the first time at room temperature in structurally disordered calcium strontium tungstate powder, Ca0.60Sr0.40WO4 (CSW), obtained by the polymeric precursor method. The PL behavior of CSW powders has been analyzed as a function of the disorder rate, based on experimental and theoretical studies. Quantum mechanical theory based on density functional theory at the B3LYP level has been employed to study the electronic structure of two periodic models representing both crystalline and disordered powders. Their electronic structures have been analyzed in terms of density of states, band dispersion and charge densities. The calculations indicate a break in symmetry when passing from crystalline to disordered models, creating localized electronic levels above the valence band. Moreover, a negative charge transfer process takes place from the [WO3] cluster to the [WO4] cluster. The polarization induced by the break in symmetry and the existence of localized levels favors the creation of trapped holes and electrons, originating the PL phenomenon. (c) 2007 Elsevier B.V.

First Report on Rotenoids as Neurotoxic Principles of Seeds from Aeschynomene indica (Leguminosae)

Toxic principles from seeds of Aeschynomene indica collected in Brazil were analyzed. Dalpanol, 12 alpha-hydroxydalpanol and 11-hydroxydalpanol were identified using (1)H NMR in A. indica for the first time. 11-hydroxydalpanol has not been previously reported in the existing literature. Furthermore these rotenoids are likely the toxic principles that cause neurological signs in mice.

Podolsky's higher-order electromagnetism from first principles

Podolsky's higher-order field equations are obtained by generalizing the laws of Podolsky's electrostatics, which follow from Coulomb's generalized law and superposition, to be consistent with special relativity. In addition, it is necessary to take into account the independence of the observed charge of a particle on its speed. It is also shown that the gauge-independent term concerning the Feynman propagator for Podolsky's generalized electrodynamics has a good ultraviolet behaviour at the expense of a negative metric massive ghost which, contrary to what is currently assumed in the literature, is non-tachyonic. A brief discussion on Podolsky's characteristic length is presented as well.

Evaluation of a new intraoral paralleling device for creating guiding planes: A pilot study

Aim: The aim of the study was to assess the accuracy of a new intraoral paralleling device for creating proximal guiding planes for removable partial dental prostheses. Methods and Materials: Thirty gypsum casts were divided into two groups in which the proximal surfaces of selected teeth were prepared using either a surveying device (Group 1) or the new ParalAB paralleling device (Group 2). In each cast guiding planes were prepared on the distal surface of the maxillary left canine (A), on the mesial and distal surfaces of the maxillary left second molar (B and C), and on the distal surface of the maxillary right canine (D). Each prepared surface formed an angle related to the occlusal plane that was measured five times and averaged by one operator using a tridimensional coordinate machine. Results: The mean guiding plane angles (± standard deviation) for the prepared surfaces were A=91.82° (±0.48°, B=90.47° (±0.47°, C=90.21° (±0.76°, and D=90.50° (±0.73°) for the dental surveyor (Group 1) and A=92.18° (±0.87°), B=90.90° (±0.85°), C=90.07° (±0.92°), and D=90.66° (±0.76°) for the ParalAB paralleling device (Group 2). A two-way ANOVA, Tukey's, and Levène's tests (at p<0.05) revealed statistically significant differences among surfaces prepared by both groups and that one surface Conclusions: The ParalAB device was able to prepare parallel surfaces and despite significant difference between groups, the ParalAB presented a small deviation from absolute parallelism and can be considered a valid method to transfer guide plans in the fabrication of removable partial dentures. Clinical Significance: The preparation of suitable guiding planes on abutment teeth during the fabrication of removable partial dentures is dependent on the ability of the operator and requires considerable chair time. When multiple teeth are involved, achieving parallelism between abutment surfaces can be technically challenging, especially in posterior regions of the mouth. The ParalAB prototype intraoral paralleling device can aid the clinician during the preparation of accurate guiding planes with a minimum degree of occlusal divergence. © 2010 Seer Publishing LLC.

Influence of hydric stress in the production of toxic principles in Nerium oleander L.

Many plants utilized in the urban center shows substances considered toxic whose production could be influenced by some factors, like hydric stress, including ornamental Nerium oleander L., widely used in gardens in various parts of the world, which presents production of cardioative glucosides, considered toxic. This study had the objective to evaluate the effect of field capacity in the biomass and the level of cardioative glucosides in seedlings of Nerium oleander. The experiment was carried at UNIDERP, in Campo Grande City, Mato Grosso do Sul State, Brazil, at the University for Development of State and Pantanal Region, using the experimental delineation in randomized blocks. There were 4 treatments (25%; 50%; 75% and 100% of the field capacity), 5 replications and 4 plants by parcel, totalling 80 plants. The evaluations were realized 60 days after the seedlings were planted. The quantitative analysis of the cardioative glucosides was realized by gravimetric test, after selective extraction of the glucosides. Were conclude that increase of the quantity of water in the soil raised the biomass production until 75% of the field capacity and increased the level of cardioative glucosides, showing that water management is very important and should be provided only the necessary to development of the plant.

Doppler ultrasonography principles and methods of evaluation of the reproductive tract in mares

Background: Doppler ultrasonography is a non-invasive real time pulse-wave technique recently used for the transrectal study of the reproductive system hemodynamics in large animals. This technic is based in the Doppler Effect Principle that proposes the change in frequency of a wave for an observer (red blood cells) moving relative to the source of the respective wave (ultrasonic transducer). This method had showed to be effective and useful for the evaluation of the in vivo equine reproductive tract increasing the diagnostic, monitoring, and predictive capabilities of theriogenology in mares. However, an accurate and truthful ultrasonic exam requires the previous knowledge of the Doppler ultrasonography principles. Review: In recent years, the capabilities of ultrasound flow imaging have increased enormously. The current Doppler ultrasound machines offer three methods of evaluation that may be used simultaneously (triplex mode). In B-mode ultrasound, a linear array of transducers simultaneously scans a plane through the tissue that can be viewed as a two-dimensional gray-scale image on screen. This mode is primarily used to identify anatomically a structure for its posterior evaluation using colored ultrasound modes (Color or Spectral modes). Colored ultrasound images of flow, whether Color or Spectral modes, are essentially obtained from measurements of moving red cells. In Color mode, velocity information is presented as a color coded overlay on top of a B-mode image, while Pulsed Wave Doppler provides a measure of the changing velocity throughout the cardiac cycle and the distribution of velocities in the sample volume represented by a spectral graphic. Color images conception varies according to the Doppler Frequency that is the difference between the frequency of received echoes by moving blood red cells and wave frequency transmitted by the transducer. To produce an adequate spectral graphic it is important determine the position and size of the simple gate. Furthermore, blood flow velocity measurement is influence by the intersection angle between ultrasonic pulses and the direction of moving blood-red cells (Doppler angle). Objectively colored ultrasound exam may be done on large arteries of the reproductive tract, as uterine and ovary arteries, or directly on the target tissue (follicle, for example). Mesovarium and mesometrium attachment arteries also can be used for spectral evaluation of the equine reproductive system. Subjectively analysis of the ovarian and uterine vascular perfusion must be done directly on the corpus luteum, follicular wall and uterus (endometrium and myometrium associated), respectively. Power-flow imaging has greater sensitivity to weak blood flow and independent of the Doppler angle, improving the evaluation of vessels with small diameters and slow blood flow. Conclusion: Doppler ultrasonography principles, methods of evaluation and reproductive system anatomy have been described. This knowledge is essential for the competent equipment acquisition and precise collection and analysis of colored ultrasound images. Otherwise, the reporting of inconsistent and not reproducible findings may result in the discredit of Doppler technology ahead of the scientific veterinary community.
