Implementation of an AC model for transmission expansion planning considering reliability constraints

In this paper, a hybrid heuristic methodology that employs fuzzy logic for solving the AC transmission network expansion planning (AC-TEP) problem is presented. An enhanced constructive heuristic algorithm aimed at obtaining a significant quality solution for such complicated problems considering contingency is proposed. In order to indicate the severity of the contingency, 2 performance indices, namely the line flow performance index and voltage performance index, are calculated. An interior point method is applied as a nonlinear programming solver to handle such nonconvex optimization problems, while the objective function includes the costs of the new transmission lines as well as the real power losses. The performance of the proposed method is examined by applying it to the well-known Garver system for different cases. The simulation studies and result analysis demonstrate that the proposed method provides a promising way to find an optimal plan. Obtaining the best quality solution shows the capability and the viability of the proposed algorithm in AC-TEP. © Tübi̇tak..

Cannabidiol administration into the bed nucleus of the stria terminalis alters cardiovascular responses induced by acute restraint stress through 5-HT1A receptor

Systemic administration of cannabidiol (CBD) is able to attenuate cardiovascular responses to acute restraint stress through activation of 5-HT1A receptors. Previous results from our group suggest that the bed nucleus of the stria terminalis (BNST) is involved in the antiaversive effects of the CBD. Moreover, it has been proposed that synapses within the BNST influence restraint-evoked cardiovascular changes, in particular by an inhibitory influence on the tachycardiac response associated to restraint stress. Thus, the present work investigated the effects of CBD injected into the BNST on cardiovascular changes induced by acute restraint stress and if these effects would involve the local activation of 5-HT1A receptors. The exposition to restraint stress increased both blood pressure and heart rate (HR). The microinjection of CBD (30 and 60nmol) into the BNST enhanced the restraint-evoked HR increase, in a dose-dependent manner, without affecting the pressor response. The selective 5-HT1A receptor antagonist WAY100635 by itself did not change the cardiovascular responses to restraint stress, but blocked the effects of CBD. These results showed that CBD microinjected into the BNST enhanced the HR increase associated with acute restraint stress without affecting the blood pressure response. Although these results are not in agreement with those observed after systemic administration of CBD, they are similar to effects observed after reversible inactivation of the BNST. Moreover, similar to the effects observed after systemic administration, CBD effects in the BNST seem to depend on activation of 5-HT1A receptors. © 2012 Elsevier B.V. and ECNP.

Ab Initio correlated all electron Dirac-Fock calculations for eka-francium fluoride (E119F)

Resultados obtidos por cálculos Dirac-Fock correlacionados de 4 componentes para o fluoreto do elemento E119 (Eka-Frâncio) com base estável e precisa, livre de prolapso variacional, são reportados neste trabalho. No nível CCSD(T), a distância de equilíbrio R_e, frequência harmônica ω_e e energia de dissociação D_e são 2,432 Å, 354,97 cm_-1 e 116,92 kcal mol_-1, respectivamente. Também são reportados base livre de prolapso variacional de 4 componentes para o elemento 119, uma curva analítica de energia potencial precisa e o espectro vibracional a partir dos dados obtidos no nível CCSD(T). Nossos resultados sugerem que a molécula E119F deva ser menos iônica que seus fluoretos alcalinos homólogos mais leves, em contraste com o senso químico comum baseado nas propriedades periódicas - era de se esperar nesta molécula a ligação química mais iônica possível. Também encontramos que a correção do tipo modelo de carga para negligenciar as integrais do tipo SS resulta em erros insignificantes e acelera os cálculos cerca de 3 vezes no nível CCSD(T) e cerca de 4 vezes no nível DFT/B3LYP.

O atendimento por instituição pública de saúde: percepção de famílias de doentes com câncer

This study aimed to analyze how the families of cancer patients perceived the treatment provided at a specialist public outpatient clinic, using Bardin's method of Content Analysis. Seven families consisting of fourteen family members were interviewed. They underlined doctor-patient relationship, judging it to be impersonal and superficial, resulting in a lack of security and trust. Families try to to participate but feel undervalued and excluded from the care. Necessary information that they are not given is sought in the media, while comfort is achieved through religious or spiritual practices. Health care training must encourage professionals to view the family as a unit of care, aligning training to different modes of health care.

Vulnerabilidade, reconhecimento e saúde da pessoa idosa: autonomia intersubjetiva e justiça social

The elderly are the object of policies of protection against risks and diseases. According to the liberal premise, the idea is ensure the individual's independence, which actually serves to isolating and weakening the elderly. We propose the paradigm of recognition and social bonds that support the life of individuals who exercise recognition and are recognized. Intersubjective autonomy is guaranteed through relations of affection/friendship, social esteem, recognition of rights and responsibilities and threatened by de-valuing attitudes, disrespect and violence. This contributes to the health of the elderly, by understanding exclusion, slander and trauma and supporting the care institution with a view to integrity and social justice.

O transtorno mental na percepção de agentes comunitários de saúde na estratégia saúde da família

The Family Health Strategy facilitates user access to mental health actions. This study aimed to verify the community health agents’ perceptions of the Family Health Strategy about mental disorder. A qualitative study was conducted with 26 randomly selected community health agents, among the professionals of 13 units, which constitute the Family Health Strategy of Itapeva (SP). The community health agents responded to a personal information questionnaire and a semi-structured interview. Data were checked through content analysis. Stigmatizing perception of the mentally disturbed persons, lack of knowledge about the process of falling ill and the mental disorder evolution, and the unpreparedness to act in this population were observed. Capacitating agents enable them to contribute in a positive way to the effective functioning of a care net in mental health in the city.

Territórios e sentidos: espaço, cultura, subjetividade e cuidado na atenção psicossocial

In the light of the collective health and of the mental health, the concept of territory is present in multiple dimensions and meanings. It appears in documents that express principles and guidelines of the health policies and in the planning of local actions, and it is a central element to organize the care network in psychosocial attentiveness. This present essay aims to discuss the concept of territory and its uses in the practices of psychosocial care, developing a dialogue with the geographer Milton Santos and the philosophers Gilles Deleuze and Félix Guattari who, from different fields and perspectives, work with this concept. This dialogue made it possible to think the territory in its complexity, as space, process and composition, in order to optimize the relationship between service, culture, production of care and production of subjectivity.

Effect of chemical activation of 10% carbamide peroxide gel in tooth bleaching

This study aimed to evaluate the efficacy of chemical agents to increase the bleaching effectiveness of 10% carbamide peroxide. Two hundred and ninety enamel-dentin discs were prepared from bovine incisors. The color measurement was performed by a spectrophotometer using the CIE L*a*b*system. The groups were divided according to the bleaching treatment: negative control group (NC): without bleaching; positive control group (PC): bleached with 10% carbamide peroxide gel without any chemical activator; Manganese gluconate (MG); Manganese chloride (MC); Ferrous gluconate (FG); Ferric chloride (FC); and Ferrous sulphate (FS). Three different concentrations (MG, MC, FG, FC: 0.01, 0.02 and 0.03% w/w; FS: 0.001, 0.002 and 0.003% w/w) for each agent were tested. The bleaching gel was applied on the specimens for 8 h, after which they were immersed in artificial saliva for 16 h, during 14 days. Color assessments were made after 7 and 14 days. The data were analyzed by repeated measures analysis of variance and Tukey's test (5%). Generally, the test groups were unable to increase the bleaching effect (ΔE) significantly compared to the PC group. Only for ΔL, significant higher values compared to the PC group could be seen after 7 days in groups MG (0.02%), and FS (0.002 and 0.003%). The NC group showed significantly lower values than all tested groups. It was concluded that for home bleaching procedures, the addition of chemical activators did not produce a bleaching result significantly higher than the use of 10% carbamide peroxide without activation, and that the concentration of chemical activators used did not significantly influence the effectiveness of treatment.
