O controle da extrusão apical durante a reintervenção endodôntica é essencial para o sucesso do novo tratamento. Nesse contexto, o presente estudo teve como objetivo comparar a quantidade de material sólido extruído na desobturação de canais radiculares variando-se a técnica de esvaziamento e o limite de obturação. Foram utilizados 40 incisivos inferiores previamente tratados divididos em dois grupos de acordo com o limite de obturação estabelecido. Cada grupo foi subdividido em dois subgrupos levando-se em conta a técnica de desobturação empregada; manual (subgrupos A1 e B1) e mecânico-rotatória com limas de Ni-Ti (Quantec LX) (subgrupos A2 e B2). O material sólido extruído foi coletado por meio do sistema de filtração Millipore, levado à secagem em dessecador de sílica e pesado em balança analítica de precisão. Os resultados obtidos foram submetidos a ANOVA para dois fatores de variação sendo em seguida empregado o Teste de Tukey (&#945; = 5%). A técnica de desobturação mecânico-rotatória produziu menor extrusão (0,66mg) que a manual (1,11mg), havendo diferença estatística significante entre elas (p < 0,05). Os canais preenchidos até o vértice radiográfico apresentaram maior quantidade de extrusão (1,38mg) do que os obturados 1 mm aquém do forame (0,39mg), observando-se diferença estatística significante entre eles (p < 0,05). A menor quantidade extrusão foi observada no subgrupo A2 (0,20mg), em que foi empregada a técnica rotatória de desobturação em canais obturados 1mm aquém do forame apical, sendo constatada diferença estatisticamente significante deste subgrupo com os demais (p < 0,05). A extrusão de material sólido durante a desobturação de canais radiculares é influenciado pela técnica empregada e pelo limite apical de obturação. / The apical extrusion control during the endodontic retreatment is essential for the success of the new treatment. The purpose of this study was to compare the quantity of solid apically extruded material during filling removal according the gutta-percha removal technique and root filling limit. Forty mandibular incisors with a single straight canal were selected. The canals were previously endodontically treated and then divided into two groups according the filling level. Each group was subdivided in two groups considering the retreatment technique: stainless steel hand files (subgroups A1 and B1) versus niquel-titanium rotatory instruments (subgroups A2 and B2). The extruded solid material was collected by Millipore filtration system, dried in silica desiccators and weighed in an eletrobalance. The results were analyzed using ANOVA with two variation factors and Tukey Test (&#945; = 5%). The niquel-titanium rotatory instruments produced less extrusion (0,66mg) than the stainless steel hand files (1,11mg), with significant statistical difference between them (p < 0,05). The canals filled until the radiographic apex showed larger amount of extruded material (1,38mg) than those filled 1 mm beyond the foramen (0,39mg). It was observed significant statistical difference between them (p < 0,05). The smaller extruded debris amount was observed in subgroup A2 (0,20mg), in which one the rotary technique was used to remove the gutta-percha of canals filled 1mm beyond the apical foramen. It was verified significant statistical difference of this subgroup with the other ones (p < 0,05). The extrusion of solid material during the gutta-percha removal is influenced by the technique as well as the apical filling limit.

In the stories of olden times and in those of our own American Indians, we learned of the picture writing of primitive peoples. It became an early method of recording people's thoughts. This was a very useful method at a time when the race was young. This in turn was the beginning of our alphabet, later the beginning of shaping letters into words, and then word into sentences and paragraphs. As our world has grown older, new idea have come into use and we are no longer content to live as our grandparents lived. We travel by fast express trains, high powered auto- mobiles, airplanes, or zeppelins. The radio gives us the news before our papers containing it are on the street. are not able to talk with people on the other side of the world. Business men find this a very valuable means of doing business when time means money. The motion pictures bring us the story of the book we have not had time to read and the characters from its pages talk to us from the screen. In short, we must have quicker ways of doing things.

The aim of this qualitative interpretive research was to explore the experiences of HIV counsellors and how these experiences influence the counsellors' psychological wellbeing. The complexities of the context within which HIV pre and post test counselling occurs form the day-to-day real ity of barely trained volunteer counsellors whose task it is to counsel, inform and educate people at grass roots concerning HIV. The guiding question of the current research pertained to the experience of HIV counselors regarding the influence of their work on their own well-being. A case study design was used. In depth interviews were conducted with nine Sotho speaking HIV counselors working in primary healthcare clinics in the Sedibeng region of Gauteng. Additional data was collected through observation. Data was initially coded, using axial coding; this was followed by thematic analysis. The focus was .on the psychological well-being of the volunteer HIV counsellors. The data indicated that the participants were not overwhelmed by the many stressors of their challenging occupations. They succeeded in developing their own ways of stress relief especially through practising their spiritual beliefs and other means like participating in community activities and meaningful relationships of significant other. They experienced personal growth and empowerment in general, but especially in the field of health and sexuality. The female participants were increasingly able to negotiate safer sex. Participants' lives were enriched through amongst others the regard they received from their communities, and being in a position to give information and advice that they gained from the training and exposure to information. The participants experienced feelings of self-worth in that they were able to contribute to their communities and thereby adding meaning to their own existence. It became clear that their character strengths such as wisdom, courage, humanity, justice and transcendence enabled them to function and grow in their difficult situation. The research highlighted that the inner strengths and virtues of the volunteer counsellors enable them to persist, in challenging work conditions and socio-economic circumstances. Difficulties facing volunteer HIV counsellors that became clear are the lack of support and recognition they have to contend with. It is therefore recommended that more attention should be given by the relevant stakeholders to strengthen the support and to make more resources available to them. / Thesis (M.A. (Psychology))--North-West University, Vaal Triangle Campus, 2010.

E ainda, a relação entre esta produção de atrativos florais e o comportamento dos polinizadores potenciais, dentre estes a Apis mellifera L. (abelha africanizada), e os requerimentos de polinização da jitirana branca. A pesquisa foi realizada em uma área de preservação de Caatinga, no Campus da FATEC Sertão Central, Quixeramobim-Ceará. Foi constatado que: A jitirana branca é uma cornucópia; sua densidade floral por m² foi em média 33,7 flores; apresentou ampla gama de visitantes florais (hymenopteros, coleópteros, hemípteros, dípteros, e pássaros); seu volume de néctar variou de acordo com o horário de coleta e não há reposição de néctar na flor após as 11:00 horas (A.M.); e a polinização mais eficiente corresponde a autopolinização.
