Abstract: this paper presents a new methodology to evaluate the reliability of distribution systems considering the impact of failures from the generation and transmission (g&t) systems. therefore, an integrated adequacy evaluation, including generation, transmission and distribution, is performed in order to provide a more detailed information about interruptions experienced by consumers. the g&t systems are represented by a fictitious equivalent network, whose parameters are obtained by monte carlo non-sequential simulation. the equivalent g&t network is then connected with the distribution network and analyzed by the minimal cut-set theory. traditional distribution indices (e.g. saifi, saidi, etc.) as well as the lolc - loss of load cost - indices are disaggregated to measure the contribution of g&t and distribution systems on the overall system indices. the proposed method is applied to the ieee-rts, which represents the g&t system, connected with the rbts, which represents the distribution system. the results and their potential applications to the new power system competitive environment are discussed.

Abstract: A parasitological study was undertaken to determine the health status of 15 mouse and 10 rat colonies bred in 18 Brazilian laboratory animal houses maintained under different sanitary barrier conditions which supply animals for teaching, research purposes and manufacture of biological products for medical or veterinary use. Parasitological methods were used for diagnosis of mites, lices, helminthes and protozoan parasites. A questionnaire was answered by institutions with the intention to obtain information about the existence of barriers against infections and of regular sanitary monitoring program of their colonies. The questionnaire data show that the majority of the animal houses investigated do not possess an efficient sanitary barrier system able to keep animals under controlled health sanitary conditions. Ecto and endoparasite infections are widespread in the colonies and multiple infections were common in animals from most facilities investigated. The prevalences of parasites detected among the mouse and rat colonies of the laboratory animal houses investigated were: Myocoptes musculinus (46.6%), Myobia musculi (26.6%), Radfordia ensifera (13.3%), Syphacia obvelata (86.6%), Aspiculuris tetraptera (60.0%), Hymenolepis nana (53.3%), Spironucleus muris (80.0%), Tritrichomonas muris (80.0%), Giardia muris (66.0%), Entamoeba muris (20.0%), Eimeria sp. (13.3%), Hexamastix muris (26.6%), Poliplax spinulosa (30.0%), Poliplax serrata (10.0%), Radfordia ensifera (30.0%), Syphacia muris (80.0%), Hymenolepis nana (40.0%), Trichosomoides crassicauda (55.5%), Spironucleus muris (90.0%), Tritrichomonas muris (80.0%), Giardia muris (60.0%), Entamoeba muris (80.0%), Eimeria sp. (60.0%) and Hexamastix muris (60.0%).

Abstract: the diagnosis of avoidant disorder was deleted from the diagnostic and statistical manual of mental disorders - fourth edition (dsm-iv) based on a `committee decision' suggesting that avoidant disorder is part of the social phobia spectrum. the objective of the present study was to examine the nature of this clinical association in a referred sample of brazilian children and adolescents. we assessed a referred sample of 375 youths using semi-structured diagnostic interview methodology. demographic (age at admission to the study and sex) and clinical (level of impairment, age at onset of symptoms and pattern of comorbidity) data were assessed in subsamples of children with avoidant disorder (n = 7), social phobia (n = 26), and comorbidity between both disorders (n = 24). although a significant difference in the male/female ratio was detected among groups (p = 0.03), none of the other clinical variables differed significantly among subjects that presented each condition separately or in combination. most of the children with avoidant disorder fulfilled criteria for social phobia. thus, our findings support the validity of the conceptualization of avoidant disorder as part of the social phobia spectrum in a clinical sample.

Abstract: Dois experimentos foram conduzidos em casa de vegeta o com o objetivo de identificar, através de curvas de dose-resposta, a sensibilidade de plantas jovens e perenizadas de capim-capivara a doses crescentes (0, 25, 50, 75, 100, 125, 150, 175 e 200% da dose recomendada para gramíneas perenes) de cyhalofop-butyl (315 g i.a. ha-1), imazapic + imazapyr (24,5 g e.a. ha-1 + 73,5 g e.a. ha-1), glyphosate (2.160 g e.a. ha-1) e am nio glufosinate (900 g i.a. ha-1). O experimento 1 foi conduzido de janeiro a mar o de 2010, e o experimento 2, de janeiro de 2010 a janeiro de 2011. Plantas jovens apresentaram maior sensibilidade aos herbicidas am nio glufosinate e cyhalofop-butyl, entretanto, a morte das plantas ocorreu somente quando tratadas com glyphosate e a mistura formulada de imazapic + imazapyr. Em plantas perenizadas, os herbicidas n o proporcionaram controle satisfatório. Two experiments were conducted under greenhouse conditions to identify, based on dose-response curves, the sensitivity of young and perennial plants of West Indian Marsh grass to increasing doses (0, 25, 50, 75, 100, 125, 150, 175 and 200% of the recommended dose for perennial grasses) of cyhalofop butyl (315gc.p. ha-1), imazapic + imazapyr (24.5gc.p. ha-1 + 73.5gc.p. ha-1), glyphosate (2,160gc.p. ha-1) and ammonium glufosinate (900gc.p. ha-1). Experiment I was conducted from January to March 2010 and Experiment II, from January 2010 to January 2011. Young plants showed higher sensitivity to ammonium glufosinate and cyhalofop butyl; however, death occurred only when the plants were treated with glyphosate and a formulated mixture of Imazapic + Imazapyr. The herbicides did not provide satisfactory control against the perennial plants.
