Dados batimétricos detalhados obtidos na antepraia adjacente ao Molhe Oeste conhecida como banco das Três Marias, evidenciaram a presença de uma fossa junto a extremidade do molhe e um banco na forma de domo a SO da depressão. O banco tem sua base e crista respectivamente nas cotas de 8 e 6 m. A feição é aproximadamente oval, com o eixo maior semiparalelo à costa (sentido NNE – SSO) medindo aproximadamente 1600 m. O eixo menor, quase transversal à costa (sentido L-O), apresenta cerca de 1200 m de extensão. O banco representa o resquício do lobo terminal do delta de maré vazante (barra) da laguna formado durante a fixação de sua desembocadura. A fossa junto ao cabeço do molhe apresenta pendente íngreme, que inicia na isóbata de 8 m e alcança a isóbata dos 17 m, sendo provavelmente formada pela ação da corrente longitudinal de SO para NE. Foram coletadas também amostras de sedimento. Estes dados evidenciaram ao menos três subambientes refletindo diferentes níveis de energia. Do mais enérgico para o menos: o banco, onde o sedimento é mais grosso e melhor selecionado, a antepraia, com o sedimento pouco mais fino e a fossa, onde foi amostrada lama, mal selecionada.

Currently, the biodiversity is considered as a powerful food security strategy, ecological and economical for humanity. Brazil is one of the main centers of genetic diversity of native fruit in the world. However, little is known about most of these species. In southwestern Paraná region, this diversity can be found, however, due to human action to increase genetic erosion, it is losing genotypes with potential for use. Thus, the conservation of genetic resources is essential for reduction strategies for damage caused to the environment and the lack of tech-nical information to increase the use of them. This study aimed to obtain information for cre-ating on farm net conservation in four citties this region. This study was carried out in rural properties from Dois Vizinhos, Itapejara D’Oeste, Verê and São Jorge D'Oeste citties, Paraná State, Brazil. It was action plan was established with the rural communities through gathering information with agents considered key in the process, it seeking the greatest number of farm-ers who had their properties in the native fruits as pitanga, jabuticaba, uvaia, cereja-do-mato, guabiroba, guabiju, sete capote, goiaba serrana, araça amarelo e vermelho trees. Semi-structured questionnaire was applied, which concerned issues of presence, handling and use of Myrtaceae fruit trees on their properties and informed consent term. There was a survey of the number and native fruits present in each property. The characterization of each household in terms of diversity handled and used in native fruit was performed. It was realized the soil col-lect in 200 properties with the presence of at least some native fruit tree naturally occurring, in order to determine the preference of the species for the chemical characteristics of the soil. The four citties have native fruits trees in quantity and diversity for the creation of on farm net conservation, with farmers demonstrating knowledge of their role as guardians of this heritage of humanity.

The most native fruit trees are belonging to Myrtaceae family, which it have as main marketing potential their fruit. Despite the wide acceptance of the fruits of these native fruit cultura, the establishment of commercial orchards is still necessary, because if it prevails extraction in the forest. To start the cultivo in the orchard, the first point is on the mother plant choice, which should provide superior characteristics when compared to other genotypes. Then, it is necessary to choose the method to can produce satisfactory amount of seedlings and preferably without it to lose the mother plant characteristics. For this, it adopts the asexual thechniques, with option for grafting, cuttings and air layering. These techniques when tested with native fruits tree, it proved limiting in theses results, with this, it should to test other it to recommend its use, especially, those fruit native of higher potential as jabuticaba tree, pitanga tree, sete capote tree and araça amarelo tree. The aim of this study was to test the use of asexual propagation through mini-cuttings in these native fruit trees, according to the time of collection, the mini-cutting length and concentration of IBA, as well as, it to relate the results of rooting with tryptophan extracted at certain times. The work was carried out at Universidade Tecnológica Federal do Paraná – Câmpus Dois Vizinhos, Brazil. The samples were collected each two months. The mini-cutting were prepared with 6 or 8 cm, with a pair of leaves reduced to 25% of the original size. The mini-cuttings had their base immersed in liquid solution of indole-butyric acid (IBA) in the concentrations of 0, 3000 and 6000 mg L-1 and then were placed in tubes containing commercial substrate. The experimental design was completely randomized with factorial 2 x 3 x 6 (mini-cutting length x IBA concentration x time of collection), with four replications, it being each plot varied according to the amount of shoots obtained by period time. After 120 days, the rooting and callus formation (%), average number of roots per mini-cutting and the average length of the roots were evaluated. After 60 days of these evaluations, the survival of mini-cuttings rooted after transplant was evaluated. It was evaluated also the production of mini-cuttings of each size in each period time. At the end of the experiment it was evaluated the percentage of survival of mother plantlets. For analysis of tryptophan was used materials branches, leaves and twigs with leaves, taken from the materials used for the production of mini-cutting. It was recommended for hybrid jabuticaba tree the use mini-cutting with eight cm, treated with 6000 mg L-1 of IBA and collected in June. For jabuticaba tree of cabinho and araça amarelo tree the period for propagation by mini-cuttings should be in August, regardless of IBA concentration and length of the mini-cutting. In the jabuticaba tree sabara and sete capote tree is important to obtain more satisfactory results realized the collect in October or December, with the same independence of other levels tested in other factors. However, for sete capote tree should test other techniques to increase the efficiency of propagation. And with pitanga tree recommended to the collection in June, but with 6cm the application of 3000 mg L-1 of IBA and 8 cm with 6000 mg L-1 of IBA.

A avaliação do desempenho e a sua aplicação são, no actual enquadramento socioeconómico, cada vez mais necessárias, como forma de melhorar a eficácia e a eficiência entre as organizações. Para a prática profissional verifica-se que a implementação da avaliação de desempenho, apresenta lacunas que podem comprometê-la. Sabendo da importância do profissional para o sucesso da implementação da avaliação de desempenho, toma-se fundamental, analisar a sua percepção face ao modelo e sua implementação. O problema da instrução do presente estudo pretende saber quais as percepções dos técnicos de radiologia avaliados sujeitos ao modelo de avaliação de desempenho implantado no Hospital Curry Cabral. Tendo como objectivo ao nível da gestão, minimizar os obstáculos de implementação e maximizar os pontos fortes. Após pesquisa bibliográfica sobre os principais conceitos, foi definido domo objectivo da investigação empírica: - Comparar as percepções dos técnicos de radiologia submetidos ao modelo de avaliação desempenho ”Pró-Activo”. Recorrendo a uma metodologia exploratória e descritiva, estudámos o impacto dessas ferramentas utilizadas dentro da Unidade Hospitalar do estudo. A metodologia de recolha de informação aos profissionais expostos do estudo assentou em questionários de perguntas fechadas e abertas ambas com uma abordagem de carácter quantitativo. Para a análise e tratamento dos dados utilizou-se programas informáticos. As principais conclusões: verifica-se a falta de formação para todos os envolvidos, um processo desprovido de imparcialidade, neutralidade e rigor, bem como uma motivação geral dos profissionais em matéria de avaliação de desempenho. ABSTRACT - The evaluation of performance and its implementation are, in the current socioeconomic framing, each time more necessary as form to improve the effectiveness and the efficiency amidst the organizations. For the practical professional it is verified that the implementation of the performance evaluation, presents gaps that can compromise it. Knowing the importance of the individuals in the success of the implementation of the performance evaluation, it becomes basic to analyze its perceptions face to the model and its implementation. The problem of inquiry of this study pretends to know which the perceptions of the technicians of radiology evaluated and appraisers face to the models of evaluation of performance implanted in the Portuguese Hospitals (Hospital Curry Cabral). The purpose to the level of the management is to minimize the obstacles of implementation and to maximize the strong points. Bibliographical research on the main concepts was effectuated, after what we define the objectives of empirica inquiry: - To compare the perceptions of the radiology technicians subjected to models of performance evaluation “Pro-Activa”.

O objetivo deste estudo foi avaliar o efeito de fungos micorrízicos arbusculares (FMAs), da adubação e da composição do substrato no crescimento de mudas de Eugenia uniflora. As sementes foram germinadas em vermiculita média e repicadas para tubetes (100 cm3) contendo substratos à base de vermicomposto e casca de arroz carbonizada e, como controle, utilizou-se do substrato comercial à base de casca de pínus. Estes substratos foram testados com e sem inoculação micorrízica, adicionada ao substrato, como também se testaram a presença e a ausência de adubação de cobertura. Foram analisadas as propriedades físico-químicas dos substratos formulados. Avaliaram-se a altura, o diâmetro do colo, a agregação das raízes ao substrato, a biomassa seca aérea, a biomassa seca radicial e foram determinados a relação entre altura e diâmetro do colo e o índice de qualidade de Dickson. A inoculação com FMAs não influenciou no crescimento das mudas, enquanto a interação entre substratos e adubação foi significativa para a maioria das variáveis. A ausência de resposta aos FMAs foi, provavelmente, devido às altas concentrações de fósforo nestes substratos. Concluiu-se que o substrato à base de vermicomposto e casca de arroz carbonizada, na proporção de 20/80, pode ser utilizado na produção de mudas desta espécie.
