Os trabalhos de amor e outras mandingas: A experiência mágico-religiosa em terreiros de umbanda

The following text addresses the magical-religious experience carried on by many individuals when they seek to solve their love, financial and health problems by means of white magic spells done by pais-de-santo e mães-de-santo (saint s father and saint s mother) from umbanda. The rites through which this seek can be detected are free love spells, troublesolving spells, and healing spell. The concept of experience, here understood as the thing which gives sense to the sense, has been the main guiding idea of the reflections here enclosed. People who seek the umbandista spells as a way of solving their daily afflictions have the opportunity of living a rich magical-religious experience in which several dimensions intersect. Among these dimensions I decided to study the performance, the knowhow and the subjetivity. Each one gave rise to the opportunity of studying a range of other themes, such as the corporeity, the gestuality, vocality, the world knowledge, the science, the secret, the emotions and the moral. The ethnographic research was carried on in the yards which are named after Dona Luiza, Pai Gledson, Pai Salviano and Dona Terezinha umbanda, all of them situated in the town of Limoeiro do Norte, Ceará

Técnica de criação e parâmetros biológicos de Stegasta bosquella em amendoim

Studies with Stegasta bosquella in peanut crop are little explored by researchers, mainly by the need of obtaining, in the field, a large quantity of closed leaflets. Therefore, it was sought a way of rearing in a natural diet that facilitates the attainment of the insect. The research was developed at the Laboratorio de Resistencia de Plantas a Insetos (FCAV/Jaboticabal) (T: 25 +/- 2 degrees C, RH 60 +/- 10% and photophase: 12 hours) (Runner IAC 886). The rearing stock of was carried out by collecting caterpillars from the field and keeping them in flat bottom glass tubes until adult emergence and test performance. Caterpillars were individualized in Petri dish plates, lined with moistened filter paper, which contained closed and early opened leaflets, but closed with paper clips (imitating the closed leaflet). A randomized design with two treatments and 36 repetitions was used. After the pupae formation, they were separated into five couples and the adults were kept in transparent plastic cages containing a peanut stem with leaves for oviposition, and fed with a 10% honey solution. The duration and viability of the larval and pupal periods, male and female longevity with and without food, and fertility were evaluated. The two forms of larvae rearing (closed leaflet and leaflet closed with clips) did not influence on any of the studied parameters. Therefore, the rearing of S. bosquella becomes feasible in natural diet, which means there is no need to use the enclosed leaflets for this purpose, and implies the easiness for rearing.

Tabelas de Vida de Fertilidade de Brevicoryne brassicae (L.) (Hemiptera: Aphididae) em Condições de Campo

Estudos relacionados com tabelas de vida são fundamentais para o entendimento da dinâmica populacional de insetos. Neste trabalho, a espécie Brevicoryne brassicae (L.) foi estudada durante a primavera, verão, outono e inverno por meio de tabelas de vida de fertilidade, visando-se avaliar a influência da temperatura sobre sua dinâmica populacional. Para a condução dos experimentos, os pulgões foram mantidos em pequenas gaiolas fixadas em folhas de couve, Brassica oleracea L. var. acephala DC. Os parâmetros das tabelas de vida, estimados na escala de tempo em graus-dia, evidenciaram que B. brassicae apresentou maior sobrevivência nas condiç ões térmicas de outono e inverno, o mesmo ocorrendo com sua fecundidade quando as fêmeas foram submetidas às temperaturas da primavera. As elevadas temperaturas registradas no verão influenciaram adversamente a dinâmica populacional de B. brassicae, pois afetaram negativamente seu desenvolvimento, sobrevivência, longevidade e reprodução.

Vitrification with DAP 213 and Cryotop of Ex Situ and In Situ Feline Cumulus-Oocyte Complexes

This study was undertaken to compare cryotolerance, in terms of viability and resumption of meiosis after warming and culture (24 and 48 h), of ex situ (isolated) and in situ (enclosed in the ovarian tissue) feline cumulusoocyte complexes (COCs) vitrified with DAP 213 (2 M DMSO, 1 M acetamide, 3 M propylene glycol) in cryotubes or Cryotop method. Ovaries were harvested from 49 pubertal queens. of each pair of ovaries, one was dissected to release COCs randomly divided into three groups: fresh COCs (control), ex situ COCs vitrified with DAP 213 and Cryotop. The cortex of the other ovary was sectioned into small fragments (approximately 1.5 mm3) and randomly assigned to be vitrified by DAP 213 or Cryotop. After warming, ex situ and in situ (retrieved form vitrified ovarian tissue) COCs were matured in vitro. Viability of oocytes was highly preserved after warming and culture in all treatments. Proportions of oocytes surrounded by complete layers of viable cumulus cells were remarkably decreased (p < 0.00001) in both vitrification procedures compared to fresh oocytes. Resumption of meiosis occurred in all treatments. After 24 h of culture, results were similar in ex situ and in situ vitrified oocytes regardless of the vitrification protocol used (range 29-40%), albeit lower (p < 0.05) than those of fresh oocytes (65.8%). After 48 h of culture, ex situ oocytes vitrified with Cryotop achieved the rates of meiosis resumption similar to fresh oocytes (53.8% vs 67.5%; p > 0.05) and ex situ and in situ oocytes vitrified with DAP 213 showed similar rates of resumption of meiosis. These findings demonstrated that DAP 213 and Cryotop preserve the viability of ex situ and in situ oocytes, but cumulus cells are highly susceptible to vitrification. However, the capability to resume meiosis evidences that feline immature oocytes vitrified as isolated or enclosed in the ovarian cortex have comparable cryotolerance.

Simulador computacional do comportamento em regime de poços de petróleo equipados com gas-lift contínuo

Amongst the results of the AutPoc Project - Automation of Wells, established between UFRN and Petrobras with the support of the CNPq, FINEP, CTPETRO, FUNPEC, was developed a simulator for equipped wells of oil with the method of rise for continuous gas-lift. The gas-lift is a method of rise sufficiently used in production offshore (sea production), and its basic concept is to inject gas in the deep one of the producing well of oil transform it less dense in order to facilitate its displacement since the reservoir until the surface. Based in the use of tables and equations that condense the biggest number of information on characteristics of the reservoir, the well and the valves of gas injection, it is allowed, through successive interpolations, to simulate representative curves of the physical behavior of the existing characteristic variable. With a simulator that approaches a computer of real the physical conditions of an oil well is possible to analyze peculiar behaviors with very bigger speeds, since the constants of time of the system in question well are raised e, moreover, to optimize costs with assays in field. The simulator presents great versatility, with prominance the analysis of the influence of parameters, as the static pressure, relation gas-liquid, pressure in the head of the well, BSW (Relation Basic Sediments and Water) in curves of request in deep of the well and the attainment of the curve of performance of the well where it can be simulated rules of control and otimization. In moving the rules of control, the simulator allows the use in two ways of simulation: the application of the control saw software simulated enclosed in the proper simulator, as well as the use of external controllers. This implies that the simulator can be used as tool of validation of control algorithms. Through the potentialities above cited, of course one another powerful application for the simulator appears: the didactic use of the tool. It will be possible to use it in formation courses and recycling of engineers

O internato escolar O Ateneu: produção de subjetividade na instituição total

Dans cet article on cherche à identifier les effets de l'institutionnalisation dans la production de la subjectivité dans un établissement scolaire total. La recherche est basée sur le roman «O Ateneu » de Raul Pompeia, analysé à partir de la théorie de Goffman (1961-1987) relative aux institutions totales. on décrit l itinéraire moral que le personnage Sergio développe, à son entrée à l'internat, évoquant les vicissitudes par lesquelles il passe dans ce contexte institutionnel : période d'adaptation, crises évolutives, initiations sexuelles, problèmes de rivalités, etc. les établissements totaux semblent s'organiser d'une façon caractéristique et fonctionner de manière autonome. on pourra comprendre les problèmes sociaux et les effets sur la subjectivité produite par les institutions totales par l étude des relations de pouvoir subjacentes à ces types d'établissements. Le temps pendant lequel un individu vit comme interné peut laisser des marques profondes dans sa subjectivité et se configure comme un thème personnel approprié.

Anxiety-induced antinociception in mice: effects of systemic and intra-amygdala administration of 8-OH-DPAT and midazolam

Rationale: Mice exhibit antinociception after a single experience in the elevated plus maze (EPM), an animal model of anxiety. Objective: This study investigated the mechanisms involved in this form of anxiety-induced antinociception. Methods: Nociception was evaluated by means of the writhing test in mice confined either to the open or enclosed arms of the EPM. The effects of systemic (naloxone, midazolam and 8-OH-DPAT) or intra-amygdala (8-OH-DPAT. NAN-190 and midazolam) drug infusions were investigated in mice previously treated i.p. with 0.6% acetic acid, an algic stimulus that induces abdominal contortions. The effects of these drugs on conventional measures of anxiety (% entries and % time in open arms) in a standard EPM test were also independently investigated. Results: Open-arm confinement resulted in a high-magnitude antinociception (minimum 85%, maximum 450%) compared with enclosed arm confinement. The opiate antagonist naloxone (1 mg/kg and 10 mg/kg) neither blocked this open arm-induced antinociception (OAIA) nor modified indices of anxiety in EPM. Administration of midazolam (0.5-2 mg/kg, s.c.) increased OAIA and produced antinociception in enclosed confined animals, as well as attenuating anxiety in the EPM. The 5-HT(1A) receptor agonist 8-OH-DPAT (0.05-1 mg/kg, s.c.) had biphasic effects on OAIA, antagonising the response at the lowest dose and intensifying it at the highest dose. In addition, low doses of this agent reduced anxiety in the EPM. Although bilateral injections of 8-OH-DPAT (5.6 nmol/0.4 mu l) or NAN-190 (5.6 nmol and 10 nmol/0.4 mu l) into the amygdala did not alter OAIA, increased anxiety was observed in the EPM. In contrast, intra-amygdala administration of midazolam (10 nmol and 30 nmol/0.4 mu l) blocked both OAIA and anxiety. Conclusions: These results with systemic and intracerebral drug infusion suggest that 5-HT(1A) receptors localised in the amygdala are not involved in the pain inhibitory processes that are recruited during aversive situations. However, activation of these receptors does phasically increase anxiety. Although the intrinsic antinociceptive properties of systemically administered midazolam confounded interpretation of its effects on OAIA, intra-amygdala injections of this compound suggest that benzodiazepine receptors in this brain region modulate both the antinociceptive and behavioural (anxiety) responses to the EPM.

Evaluation of the elevated T-maze as an animal model of anxiety in the mouse

The elevated T-maze has been developed as an animal model of anxiety to generate both conditioned and unconditioned fears in the same rat. This study explores a version of the elevated T-maze fit for mice. Inhibitory (passive) avoidance-conditioned fear-is measured by recording the latency to leave the enclosed arm during three consecutive trials. One-way escape-unconditioned fear-is measured by recording the time to withdraw from open arms. The results showed that mice do not appear to acquire inhibitory avoidance in the standard T-maze, since their latencies to leave enclosed arm did not increase along trials. Nevertheless, the open arms seemed to be aversive for mice, because the latency to leave the enclosed arm after the first trial was lower in a T-maze with the three enclosed arms than in the standard elevated T-maze, In agreement, the exposure of mice to an elevated T-maze without shield, that reduces the perception of openness, increased significantly the latencies to leave the enclosed arm, However, the absence of the shield also increased the time taken to leave the open arms when compared to that recorded in standard T-maze. Systematic observation of behavioral items in the enclosed arm has shown that risk assessment behavior decreases along trials while freezing increases. In the open arms, freezing did not appear to influence the high latency to leave this compartment, since mice spend only about 8% of their time exhibiting this behavior, These results suggest that mice acquire inhibitory avoidance of the open arms by decreasing and increasing time in risk assessment and freezing, respectively, along three consecutive trials, However, one-way escape could not be characterized. Therefore, there are important differences between mice (present results) and rats (previously reported results) in the performance of behavioral tasks in the elevated T-maze. (C) 1999 Elsevier B.V.

Concurrent nociceptive stimulation impairs the anxiolytic effect of midazolam injected into the periaqueductal gray in mice

This study investigated whether the opportunity to avoid or escape the open arms of an elevated plus-maze (EPM) affects the antinociceptive response observed when mice are subjected to open arm confinement. Furthermore, in order to better characterize the relationship between emotion and antinociception in the EPM, we examined the behavioral effects of midazolam injection into the midbrain periaqueductal gray matter (PAG). As our main aim was to evaluate the relevance of different levels of approach-avoid conflict (i.e. The presence of open and closed arms) to maze-induced antinociception, mice were exposed to one of three types of EPM-a standard EPM (sEPM), an open EPM (oEPM: four open arms) or, as a control condition, an enclosed EPM (eEPM: four enclosed arms). Nociception was assessed using the formalin test. Twenty minutes after formalin injection (50 mu l, 2.5% formalin) into the dorsal right hind paw, mice received an intra-PAG injection of saline or midazolam (10-20 nmol). Five minutes later, they were individually exposed to one of the mazes for 10 min (25-35 min after formalin injection). Videotapes of the test sessions were scored for a variety of behavioral measures including time spent licking the formalin-injected paw. To examine whether the effects of midazolam on anxiety-like behavior may have been influenced by concurrent nociceptive stimulation (i.e. formalin pretreatment), naive mice were submitted to a similar procedure to that described above for the sEPM test but without formalin pretreatment. Results showed that mice exposed to the oEPM spent significantly less time licking the injected paw compared to groups exposed to either the sEPM or eEPM. Although exposure to the sEPM induced anxiety-like behaviors (i.e. open arm avoidance), it did not result in antinociception. Intra-PAG infusions of midazolam failed to block oEPM-induced antinociception or to alter sEPM-induced anxiety in mice that had received formalin injection. However, under normal test conditions (i.e. in the absence of formalin-induced nociceptive stimulation), intra-PAG midazolam produced clear anti-anxiety effects in mice exposed to the sEPM. Findings are discussed in terms of different emotional states induced by the oEPM and sEPM and the influence of concurrent nociceptive stimulation on the anti-anxiety effect of intra-PAG midazolam.
