Distribution line models analysis for loss calculation within three-phase three-wire power flow algorithms

Three-phase three-wire power flow algorithms, as any tool for power systems analysis, require reliable impedances and models in order to obtain accurate results. Kron's reduction procedure, which embeds neutral wire influence into phase wires, has shown good results when three-phase three-wire power flow algorithms based on current summation method were used. However, Kron's reduction can harm reliabilities of some algorithms whose iterative processes need loss calculation (power summation method). In this work, three three-phase three-wire power flow algorithms based on power summation method, will be compared with a three-phase four-wire approach based on backward-forward technique and current summation. Two four-wire unbalanced medium-voltage distribution networks will be analyzed and results will be presented and discussed. © 2004 IEEE.

A presença da literatura/cultura portuguesas em periódicos paulistas - 1900-1922

Partindo-se do pressuposto de que existe uma interligação, por meio da presença da literatura/cultura portuguesa, entre Portugal e a cidade de São Paulo – no período de 1900-1922, caracterizado ainda como pré-modernista brasileiro –, a proposta deste texto dirige-se ao comentário de alguns periódicos (O Estado de S. Paulo; A Vida Moderna; O Pirralho), visto que “[...] há uma história da literatura que se projeta na cidade de S. Paulo; e há uma história da cidade de S. Paulo que se projeta na literatura.” (CANDIDO, 1975). Assim, pretende-se verificar como a presença da literatura/cultura portuguesa (principalmente autores canônicos do século XIX) repercutiu na vida social e intelectual da cidade de São Paulo, para melhor compreensão das formas de sociabilidade, bem como a caracterização das diferentes etapas percorridas pela literatura brasileira em São Paulo.

Entre o acadêmico e o jornalístico: análise da coluna de crítica literária Prosa de Sábado, do suplemento Sabático

The literary criticism was developed in Brazil in the period that comprehends the end of the 19th century and the beginning of the 20th century. During that time, the mean of dissemination of the criticism were the footnotes of the newspapers, places in which literature was discussed and the critics expressed their personal impressions about literary works with the objective of orientating the good taste of the readers. With the progressive evolution of journalism and of the newspaper's audience, the criticism columns became incompatible with the informative part of the periodicals, being transferred to the literary supplements, during a transition phase, until it was concentrated in the universitary field. This change in the paradigms of the production of criticism also caused a change in the profile of the literary critics and in the criteria to do the criticism. Before, if the critics were professionals that only needed to have enough erudition to judge the literary works, they turn into literature experts and need to use scientific methodologies in the literary analysis, while the cultural journalist begins to look at the events and literary works as products which belong to a market that needs to be reported. This research proposes studying and comparing the critics published in the column Prosa de Sábado, of the literary supplement Sabático, produced by Silviano Santiago, critic of an academic origin, and Sérgio Augusto, journalist critic, with the objective of identifying similarities and contrasts between them, and analyse the relation of this critics with their distinct fields of literary legitimation, as well as reflecting about the presence of the literary criticism and of the critics in the current press

Autoria, deriva e contingente: intersecções sobre a análise linguística e a literária

The aim of this article is to discuss the contingence in literature texts since an approach that make the literary theory, the discourse analysis and the psychoanalysis dialogue. It is important to remark the importance of this different areas dialogue as an instrument that could help the understanding of the relations between tradition and invention and the modern writer’s obsession to control the derive of meanings and the originality of the creations as well.

Anxiolytic-like effect of way-100635 microinfusions into the median (but not dorsal) raphe nucleus in mice exposed to the plus-maze: influence of prior test experience

Studies in several laboratories have confirmed the anxiolytic potential of a wide range of 5-HT1A receptor antagonists in rats and mice, with recent evidence pointing to a postsynaptic site of action in the ventral hippocampus. It would, therefore, be predicted that blockade of 5-HT1A somatodendritic autoreceptors in the midbrain raphe nuclei should produce anxiogenic-like effects. To test this hypothesis, we investigated the effects of WAY-100635 microinfusions (0, 1.0 or 3.0 mug in 0.1 mul) into the dorsal (DRN) or median (MRN) raphe nuclei on behaviours displayed by male Swiss-Webster mice in the elevated plus-maze. As this test is sensitive to prior experience. The effects of intra-raphe infusions were examined both in maze-naive and maze-experienced subjects. Sessions, were videotaped and subsequently scored for conventional indices of anxiety (open arm avoidance) and locomotor activity (closed arm entries), as well as a range of ethological measures (e.g. risk assessment). In maze-naive mice, intra-MRN (but not intra-DRN) infusions of WAY-100635 (3.0 mug) increased open arm exploration and reduced risk assessment. Importantly, these effects could not be attributed to a general reduction in locomotor activity. A similar, though somewhat weaker, pattern of behavioural change was observed in maze-experienced animals. This unexpected anxiolytic effect of 5-HT1A autoreceptor blockade in the MRN cannot be accounted fur by a disinhibition of 5-HT release in forebrain targets (e.g. hippocampus and amygdala), where stimulation of postsynaptic 5-HT1A receptors enhances anxiety-like responses. However, as the MRN also projects to the periaqueductal gray matter (PAG), an area known to be sensitive to the anti-aversive effects or 5-HT, it is argued that present results may reflect increased 5-HT release at this crucial midbrain locus within the neural circuitry of defense.

Influence of arginine vasopressin receptors and angiotensin receptor subtypes on the water intake and arterial blood pressure induced by vasopressin injected into the lateral septal area of the rat

In this study we investigated the influence of d(CH2)(5)-Tyr(Me)-[Arg(8)]vasopressin (AAVP) and [adamanteanacetyl(1),0-ET-DTyr(2), Val(4), aminobutyryl(6), Arg(8,9)]-[Arg(8)]vasopressin (ATAVP), which are antagonists of vasopressin V-1 and V-2 receptors, and the effects of losartan, a selective angiotensin AT(1) receptor antagonist, and CGP42112A, a selective AT(2) receptor antagonist, injected into the lateral septal area (LSA) on thirst and hypertension induced by [Arg(8)]vasopressin (AVP). AAVP and ATAVP injected into the LSA reduced the drinking responses elicited by injecting AVP into the LSA. Both the AT(1) and AT(2) ligands administered into the LSA elicited a concentration-dependent decrease in the water intake induced by AVP injected into the LSA, but losartan was more effective than CGP42112A. The increase in MAP, due to injection of AVP into the LSA, was reduced by prior injection of AAVP from 18 +/- 1 to 6 +/- 1 mm Hg. Losartan injected into the LSA prior to AVP reduced the increase in MAP to 7 +/- 0.8 mm Hg. ATAVP and CGP42112A produced no changes in the pressor effect of AVP. These results suggest that the dipsogenic effects induced by injecting AVP into the LSA were mediated primarily by AT(1) receptors. However, doses of losartan were more effective when combined with CGP42112A than when given alone, suggesting that the thirst induced by AVP injections into LSA may involve activation of multiple AVP and angiotensin II receptor subtypes. The pressor response of AVP was reduced by losartan and by AAVP. CGP42112A and ATAVP did not change the AVP pressor response. These results suggest that facilitator effects of AVP on water intake are mediated through the activation of V-1 receptors and that the inhibitory effect requires V-2 receptors. The involvement of AT(1) and AT(2) receptors can be postulated. Based on the present findings, we suggest that the AVP in the LSA may play a role in the control of water and arterial blood pressure balance. (C) 2004 Elsevier B.V. All rights reserved.

Influence of implants with different sizes and configurations installed immediately into extraction sockets on peri-implant hard and soft tissues: an experimental study in dogs

Aim: To study the influence on the healing of soft and hard peri-implant tissues when implants of different sizes and configurations were installed into sockets immediately after tooth extraction.Material and methods: Transmucosal cylindrical implants, 3.3 mm in diameter in the control sites, and conical 5 mm in diameter in the test sites, were installed into the distal socket of the fourth mandibular premolars in dogs immediately after tooth extraction. After 4 months, the hard and soft tissue healing was evaluated histologically. Results: All implants were integrated in mineralized mature bone. Both at the test and control sites, the alveolar crest underwent resorption. The buccal bony surface at the implant test sites (conical; 3.8 mm) was more resorbed compared with the control sites (cylindrical; 1.6 mm). The soft tissue dimensions were similar in both groups. However, in relation to the implant shoulder, the peri-implant mucosa was located more apically at the test compared with the control sites.Conclusion: The present study confirmed that the distance between the implant surface and the outer contour of the buccal alveolar bony crest influenced the degree of resorption of the buccal bone plate. Consequently, in relation to the implant shoulder, the peri-implant mucosa will be established at a more apical level, if the distance between the implant surface and the outer contour of the alveolar crest is small.
