DESCONEXÕES DO SISTEMA DE TRANSPORTES NO MUNICÍPIO DE NOVA IGUAÇU/RJ: BUSCA POR RESPOSTAS E PROVÁVEIS CONSTATAÇÕES ACERCA DA PROBLEMÁTICA

Os transportes públicos são objetos utilizados por muitos pesquisadores para estudar o espaço geográfico e a sua organização. A abordagem do sistema de transporte no município de Nova Iguaçu, no estado do Rio de Janeiro, possui relevância por se tratar de uma área de grandes dimensões que não possui uma ligação eficiente entre suas áreas. Ao se planejar e gerir o sistema de transportes é de extrema relevância considerar as políticas urbanas a serem adotadas e as sustentabilidades a serem alcançadas. São requisitos importantes que interferem não somente na logística do município, mas também na qualidade do serviço prestado à população e ao ambiente.

O PAPEL DA COMUNICAÇÃO FACE A FACE NAS ORGANIZAÇÕES NO CONTEXTO DA SOCIEDADE MIDIATIZADA

Este estudo trata da comunicação face a face nas organizações sob diferentes abordagens teóricas. Considera a perspectiva da simultaneidade dos meios, já que as empresas utilizam diversos canais para dialogar com seus públicos de interesse. Leva em conta o fenômeno da midiatização, que reestrutura o modo como as pessoas se relacionam na sociedade contemporânea. O objetivo geral da pesquisa é sistematizar papeis potencialmente exercidos pela interação face a face e conhecer algumas circunstâncias que envolvem sua prática nas organizações. Por se tratar de uma tese teórica, a pesquisa bibliográfica se apresenta como um dos principais procedimentos metodológicos; análises de casos empíricos e um estudo de caso desenvolvido na Embrapa Pantanal constituem situações ilustrativas. Conclui-se que a comunicação face a face nas empresas ocorre de forma simultânea e combinada a outros canais de comunicação, porém, ela proporciona resultados práticos e filosóficos ainda pouco explorados. É rara a utilização estratégica de contatos presenciais como mecanismo para estabelecer relacionamentos, conhecer as reações alheias e ajustar a comunicação, aliar o discurso corporativo às práticas empresariais e avaliar o contexto onde se desenvolvem as interações, o que pode ser decisivo para a comunicação organizacional.

A presença da produção científica em psicologia na formação de psicólogos do Rio Grande do Norte

The present research aimed to analyze the presence of national scientific production in undergraduate studies in Psychology of Rio Grande do Norte. Therefore, the bibliographical references contained in education plan of subjects linked to the common center of the courses, which were taught in 2011 in three Psychology courses of the state, were focused. The analysis of the material was based on bibliographical and contextual aspects of the production, such as year, nationality, type of material, authorship (including the link of authors to PPGs), structuring axis of the subject in which it was mentioned, among others. The results showed that the national production is predominant in all courses, and they are, mostly, originated from PPGs of Psychology. Among these, the publications resulted from programs in Southwest, with emphasis to PUC-SP, are recent (mostly from 2000s) and they are predominantly composed by books (organizations and full texts). Regarding the distribution of Psychology PPGs production by the structuring axes, it is observed that it surpasses the foreign production only in axis C (procedures of scientific investigation and professional practice) and axis F (professional practices). Accordingly, it is concluded that Psychology production is found in graduation, sharing space with foreign publications and from other areas of knowledge. On the one hand, this is positive, by taking into account the importance of several foreign works and from other fields to build the knowledge in Psychology; on the other hand, it shows that the production from this area is inserted in graduation in a less significant way than its growth, which points out the existence of gaps in the development of some investigative domains from national Psychology

Lesmas do gênero Omalonyx d'Orbigny, 1837 são hermafroditas, herbívoras, de distribuição neotropical e vivem em plantas aquáticas, nas demais vegetações adjacentes e em solo úmido próximo a ambientes de água doce. No presente trabalho reporta-se a ocorrência atípica de O. pattersonae Tillier, 1981 e de Omalonyx sp. em área de terra firme, distante de ambiente aquático.

Trypanosoma Cruzi Strains From Triatomine Collected In Bahia And Rio Grande Do Sul, Brazil.

Collection of triatomines in domestic, peridomestic and sylvatic environments in states of Bahia and Rio Grande do Sul, Northeastern and Southern Brazil respectively, and isolation of Trypanosoma cruzi strains. First, the captured triatomines were identified using insect identification keys, then their intestinal content was examined by abdominal compression, and the samples containing trypanosomatid forms were inoculated in LIT medium and Swiss mice. Six triatomine species were collected in cities in Bahia, namely Panstrongylus geniculatus (01), Triatoma melanocephala (11), T. lenti (94), T. pseudomaculata (02), T. sherlocki (26) and T. sordida (460), and two in cities in Rio Grande do Sul, namely T. circummaculata (11) and T. rubrovaria (115). Out of the specimens examined, T. cruzi was isolated from 28 triatomine divided into four different species: T. melanocephala (one), T. lenti (one), T. rubrovaria (16) and T. sordida (10). Their index of natural infection by T. cruzi was 6.4%. The isolation of T. cruzi strains from triatomines found in domestic and peridomestic areas shows the potential risk of transmission of Chagas disease in the studied cities. The maintenance of those T. cruzi strains in laboratory is intended to promote studies that facilitate the understanding of the parasite-vector-host relationship.

Chromobacterium Amazonense Sp. Nov. Isolated From Water Samples From The Rio Negro, Amazon, Brazil.

The taxonomic position of a bacterium isolated from water samples from the Rio Negro, in Amazon, Brazil, was determined by using a polyphasic approach. The organism formed a distinct phyletic line in the Chromobacterium 16S rRNA gene tree and had chemotaxonomic and morphological properties consistent with its classification in this genus. It was found to be closely related to Chromobacterium vaccinii DSM 25150(T) (98.6 % 16S rRNA gene similarity) and shared 98.5 % 16S rRNA gene similarity with Chromobacterium piscinae LGM 3947(T). DNA-DNA relatedness studies showed that isolate CBMAI 310(T) belongs to distinct genomic species. The isolate was readily distinguished from the type strain of these species using a combination of phenotypic and chemotaxonomic properties. Thus, based on genotypic and phenotypic data, it is proposed that isolate CBMAI 310(T) (=DSM 26508(T)) be classified in the genus Chromobacterium as the type strain of a novel species, namely, Chromobacterium amazonense sp. nov.

Quantificação de fluxos de mercúrio gasoso na interface solo/atmosfera utilizando câmara de fluxo dinâmica: aplicação na bacia do Rio Negro

Gaseous mercury sampling conditions were optimized and a dynamic flux chamber was used to measure the air/surface exchange of mercury in some areas of the Negro river basin with different vegetal coverings. At the two forest sites (flooding and non-flooding), low mercury fluxes were observed: maximum of 3 pmol m-2 h-1 - day and minimum of -1 pmol m-2 h-1 - night. At the deforested site, the mercury fluxes were higher and always positive: maximum of 26 pmol m-2 h-1 - day and 17 pmol m-2 h-1 - night. Our results showed that deforestation could be responsible for significantly increasing soil Hg emissions, mainly because of the high soil temperatures reached at deforested sites.

Um novo índice de qualidade das águas para proteção da vida aquática aplicado ao Rio Atibaia, região de Campinas/Paulínia-SP

In this paper a water quality index is developed to subsidize management actions in the Atibaia River for upon protection of aquatic organisms. This index is composed of two measurable environmental parameters normaly, ammonia and dissolved oxygen, the latter representing the contribution of organic matter. Concentrations of these two variables were normalized on a scale from 0 to 100 and translated into statements of quality (excellent, good, regular, bad and very bad). The index was applied to three monitoring points in the Atibaia River and compared to other indices used by the State of São Paulo Environmental Agency (CETESB). The results showed that the degradation in this watershed follows the urban population density. The developed index is more restricted than the other ones routinely used to infer water quality.

Estudo da capacidade de complexação e sua relação com algumas variáveis ambientais em cinco represas do Rio Tietê/Brasil

The copper and cadmium complexation properties in natural sediment suspensions of reservoirs of the Tietê River were studied using the solid membrane copper and cadmium ion-selective electrodes. The complexation and the average conditional stability constants were determined under equilibrium conditions at pH=6.00 ± 0.05 in a medium of 1.0 mol L-1 sodium nitrate, using the Scatchard method. The copper and cadmium electrodes presented Nernstian behavior from 1x10-6 to 1x10-3 mol L-1 of total metal concentration. Scatchard graphs suggest two classes of binding sites for both metals. A multivariate study was done to correlate the reservoirs and the variables: complexation properties, size, total organic carbon, volatile acid sulfide, E II and pH.

Levantamento e características ecológicas de orchidacea e da mata ciliar do rio dourados, Dourados-MS

The Orchidaceae is one of the largest flowering plants family and with a great importance to conservation. However, no survey on orchid flowers can be found in Mato Grosso do Sul. Thus, the objective of this work was to make a survey of the Orchidaceae species and of its ecology features in a riparian forest in a fragment of Floresta Estacional Semi-Decidual that belongs to the riparian forest of the Dourados River. The inventory was made by using a sweeping method for collection, and in addition to this the vertical and horizontal position of epiphytes were assessed on the hosts. For characterization of microclimate, it was used a thermohygrometer and luximeter. It was identified 17 species of 13 genera. Of the listed genera, the most abundant ones were: Acianthera, Macradenia and Capanemia. It was also noted a vertical and horizontal distribution of the Orchidaceae in relation to inverse gradient of water and light availability. Some species tended to be sensitive to height level categorization, whereas others seemed to occur with similar frequency along the host. In relation to the cardinal orientation, the apparent preferential response for south and east directions was associated to the low sampling effort and lower water availability, which could occur because the north face is opposed to the water body.

Análise de aspectos socioeconômicos e tecnológicos da agropecuária na Bacia Hidrográfica do Rio Mogi Guaçu

Currently, owing to the occurrence of environmental problems, along with the need of environmental preservation, both the territory management of Hydrographic Basin and the conservation of natural resources have proven to have remarkable importance. Thus, the mean goal of the research is to raise and scrutinize social-economic and technologic data from the Mogi Guaçu River Hydrographic Basin (São Paulo, Brazil). The aim is to group municipalities with similar characteristics regarding the collected data, which may direct joint actions in the Hydrographic Basin Management. There were used both the methods of factorial analysis and automatic hierarchical classifications. Additionally, there is going to be applied a Geographical Information System to represent the outcomes of the methods aforementioned, through the evolvement of a geo-referenced database, which will allow the obtainment of information categorically distributed including theme maps of interest. The main characteristics adopted to group the municipalities were: agricultural area, sugar cane production, small farms, animal production, number of agriculture machinery and equipments and agricultural income. The methodology adopted in the Mogi Guaçu River Hydrographic Basin will be analyzed vis-à-vis its appropriateness on basin management, as well as the possibility of assisting the studies on behalf of the São Paulo Hydrographic Basin groups, to regional development.

Field work was carried out from April/1998 to May/1999, when montly visits were conducted to collect botanical material along trails and of the main road. The floristic survey resulted in 22 taxa belonging to eight genera. An identification key, descriptions, illustrations and comments on the analyzed taxa are presented.

Lianas da estação ecológica do Noroeste Paulista, São José do Rio Preto/Mirassol, SP, Brasil

Lianas are characteristic, abundant and ecologically important members of tropical forest but they have been neglected in floristics and phytossociological studies. This work presents a floristic survey of the lianas species at Estação Ecológica do Noroeste Paulista (EENP), and a comparison of the list of species recorded in this work with those reported for other fragments of São Paulo state. The EENP (20º48'36'' S and 49º22'50'' W) is at 468 m of altitude and comprises an area of 168,43 ha, divided into three fragments of vegetation. Samples of lianas were collected in the interior and along the edges of the forest fragments. It was identified 105 species: 99 Magnoliopsida (60 genera and 22 families); six Liliopsida (three genera and three families). The richest families in species comprised 59% of the total of lianas sampled. The dendrogram of similarity showed a low similarity between the forest situated in the littoral (Atlantic Forest) and those located in the interior of the state of São Paulo. Some other authors, also analysing the similarity of forest of the interior and Atlantic Forest of São Paulo state, but considering only the trees reported similar result.

Flora arbórea da bacia do rio Tibagi (Paraná, Brasil): Celastrales sensu Cronquist

A study of the tree species of the order Celastrales sensu Cronquist from the Tibagi river basin, Paraná state, Brazil, is presented, based on herbarium material. This basin is subdivided into three zones, from north to south: lower Tibagi (BT), mid Tibagi (MT) and upper Tibagi (AT), each with different environmental conditions and vegetation types. The order Celastrales is represented in the basin by 15 tree species belonging to three families: Aquifoliaceae, Celastraceae and Icacinaceae. Icacinaceae has only two species, Citronella gongonha and C. paniculata. The former is distinguished by a glabrous ovary and leaves that usually bear thorns. Aquifoliaceae has six species: Ilex brasiliensis, I. brevicuspis, I. chamaedryfolia, I. dumosa, I. paraguariensis and I. theezans. These species are found mainly in AT and MT and are distinguished by leaf size, indument, apices and margins, and by sepal features. Celastrales is represented by seven species and two genera; Plenckia populnea, a Brazilian savannah species found only in MT, and six species of Maytenus (M. evonymoides, M. robusta, M. dasyclada, M. salicifolia, M. ilicifolia and M. aquifolia) distinguished by leaf size and margins, branch shape and number of flowers per inflorescence.
