25. Brachiaria as a Cover Crop to Improve Phosphorus Use Efficiency in a No-till Oxisol
ABSTRACT Oxidic soils are phosphorus drains in soil; hence, P availability is a limiting factor in tropical, weathered Oxidic soils. It has been shown that some brachiarias grown as cover crops may increase soil available P to subsequent crops. The objective of this study was to evaluate soil P cycling and availability, as well as the response of soybean to

26. Bryophyte communities of restingas in Northeastern Brazil and their similarity to those of other restingas in the country
ABSTRACT Restingas are a coastal component of the Atlantic Forest. They experience high temperatures and possess soils with a low capacity to retain water, low nutrient content and high salt concentrations. Studies on bryophytes of restingas have been mostly conducted in Southeastern Brazil, and so we aimed to characterize the bryophyte flora of seven areas

27. Autumn Maize Intercropped with Tropical Forages: Crop Residues, Nutrient Cycling, Subsequent Soybean and Soil Quality
ABSTRACT Autumn maize intercropped with tropical forages can raise the amount of crop residues and improve nutrient cycling, favoring subsequent soybean crop. The objective of this study was to evaluate the effect of forms of implementation of intercropping of irrigated autumn maize with tropical forages on yield, decomposition, nutrient accumulation and rel

28. Evaluation of the relationship between the cost and properties of glass ionomer cements indicated for atraumatic restorative treatment
The aim of this study was to evaluate microshear bond strength (μSBS), water sorption and solubility of glass ionomer cements (GIC) indicated for atraumatic restorative treatment (ART). Cylindrical specimens (6x2.4 mm) were used to test the sorption and solubility of each GIC (n = 5). The specimens were weighed before and after immersion in water and desicc

29. Campomanesia adamantium (Cambess.) O. Berg seed desiccation: influence on vigor and nucleic acids
O objetivo desse trabalho foi avaliar a sensibilidade à dessecação em sementes de Campomanesia adamantium, por meio de secagem em sílica gel ativada (rápida) e em condições de laboratório (lenta). Para avaliar a sensibilidade à dessecação das sementes, realizou-se a secagem com sílica gel e secagem em condições de laboratório (25 °C) visando

30. Physiological and biochemical changes during the loss of desiccation tolerance in germinating Adenanthera pavonina L. seeds
RESUMO Nós investigamos a perda da tolerância à dessecação (TD) em sementes deAdenanthera pavonina durante a germinação. Sementes submetidas à embebição por 0, 24, 36, 48, 60 e 81 h foram secas até à umidade inicial (13%), reidratadas e avaliadas quanto à sobrevivência (retomada do crescimento e formação de plântulas normais) e à integridad

31. Characteristics of dr1790 disruptant and its functional analysis in Deinococcus radiodurans
Deinococcus radiodurans (DR) is an extremophile that is well known for its resistance to radiation, oxidants and desiccation. The gene dr1790 of D. radiodurans was predicted to encode a yellow-related protein. The primary objective of the present study was to characterize the biological function of the DR1790 protein, which is a member of the ancient yellow/

32. Re-induction of desiccation tolerance after germination of Cedrela fissilis Vell. seeds
O objetivo deste trabalho foi caracterizar a re-indução da tolerância à dessecação em sementes germinadas de Cedrela fissilis, utilizando polietileno glicol (PEG 8000). As mudanças celulares foram investigadas pelas avaliações citológicas (viabilidade celular e microscopia eletrônica de transmissão), bem como a integridade do DNA durante a perda

33. Effects of solvent evaporation on water sorption/solubility and nanoleakage of adhesive systems
Objective: To evaluate the influence of solvent evaporation in the kinetics of water diffusion (water sorption-WS, solubility-SL, and net water uptake) and nanoleakage of adhesive systems. Material and Methods: Disk-shaped specimens (5.0 mm in diameter x 0.8 mm in thickness) were produced (N=48) using the adhesives: Clearfil S3 Bond (CS3)/Kuraray, Clea

35. DIETA, DINÂMICA POPULACIONAL E ECTOPARASITAS DE PHRYNOPS GEOFFROANUS (SCHWEIGGER, 1812) (TESTUDINATA, CHELIDAE) DO BAIXO SÃO FRANCISCO, POÇO REDONDO, SE. / DIET, AND POPULATION DYNAMICS OF PHRYNOPS GEOFFROANUS ECTOPARASITES (SCHWEIGGER, 1812) (TESTUDINATA, CHELIDAE) THE LOWER SAN FRANCISCO, POÇO REDONDO, SE.
Population of P. geoffroanus of Unidade Unidade de Conservação Estadual Monumento Natural Grota do Angico (MNGA) (3740W; 0939S) was studied in relation of their diet, morphometry, growth rates and mass gain, structure and dynamic population and parasites (leeches). The sampling of specimens was performed in monthly campaigns over a year (between January an

36. Manejo de Brachiaria ruziziensis com uso de herbicidas na cultura da soja em sistema de plantio direto na savana da Roraima / Management of Brachiaria ruziziensis using herbicides in soybean under no-tillage system in the savanna of Roraima
The no-tillage system for soybean is an established practice in the Roraima savanna, but it has been presenting limitations mainly about the maintenance of soil covering, due to difficulties in the establishment of cover crops after harvest of annual crops due to the long period of water deficit. An alternative that has been recommended is to conduct the ann
