Abstract: in the humid tropics, the largest obstacle to the implementation of sustainable farming systems is the reduced efficiency of nutrient use by crops. this study assesses the effectiveness of five selected rhizobia strains in symbiosis with cowpea (vigna unguiculata (l.) walp.), with the objective of replacing n fertilization in the predominant agricultural system used by smallholder farmers. the study was carried out in three adjacent areas with distinct agricultural uses: conventional tillage, itinerant agriculture, and a no-till system. the experimental design was in randomized complete blocks with four replicates and seven treatments: five rhizobia strains (br3262, br3267, br3299, inpa3-11b, and ufla 3-84) and two controls without inoculation (one without mineral n and another fertilized with 74 kg n ha-1). we measured the dry mass of 100 grains, nodules and shoots, as well as cowpea yields and calculated relative and absolute efficiency indices for dry biomass production of cowpea shoots. agricultural uses affected the number and dry mass of the nodules and, consequently, the mass of the dry plant matter and bean yield. in terms of yield, there was a major difference between the conventional and the itinerant systems. yield was around four times as high in the itinerant system (1009.9 kg ha-1 compared to 243.7 kg ha-1). under conditions of cohesion-prone soils, the system of conventional tillage reduces the possibility of cultivation of a second harvest in the year even with inoculation or n fertilization.

Abstract: Essential oils from Mentha piperita, Cymbopogon citratus, Rosmarinus officinalis, Peumus boldus and Foeniculum vulgare were extracted by hydrodistillation, chemically characterized and quantified by GC/MS and GC/FID. The principal componentes in the essential oil of M. piperita (carvone and limonene), C. citratus (geranial, neral and myrcene), R. officinalis (1,8-cineole, camphor and α-pinene), P. boldus (α-terpinyl formate, p-cymene and 1,8-cineole) and F. vulgare (methyl chavicol, limonene and fenchone) were identified. The oils were tested for antioxidant activity employing the DPPH (2,2-diphenyl-1-picryl-hydrazyl) radical-capture method, the oxidation of the β-carotene/linoleic acid system, and the ABTS radical-capture method. The essential oils were not effective. The antioxidant activities of the oils were determined by the hydroxyl method, and the highest activity (62.80%) was observed with the essential oil from M. piperita. Activities of 1.54 and 1.82 μg μg-1

Abstract: The essential oils from Mentha piperita, Cymbopogon citratus, Rosmarinus officinalis, Peumus boldus and Foeniculum vulgare were extracted by hydrodistillation and characterized and quantified by GC-MS and GC-DIC. The oils induced hemolysis with all the doses evaluated (0.6 to 1.8 μL), and the diameters of the halos varied between 9 and 15 mm. Pre-incubation of P. boldus oil with Bothrops jararacussu venom resulted in potentiation of venom-induced hemolysis (30%) (proteases and phospholipases A2). The essential oil from M. piperita (0.6 μL) inhibited venom-induced hemolysis by 45%, whereas 0.6

A Reference Model for the Analysis and Comparison of MDE Approaches for Web-Application Development  [PDF]
Jo?o de Sousa Saraiva, Alberto Rodrigues da Silva
Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.35047
Abstract: The emerging Model-Driven Engineering (MDE) paradigm advocates the use of models as first-class citizens in the software development process, while artifacts such as documentation and source-code can be quickly produced from those models by using automated transformations. Even though many MDE-oriented approaches, languages and tools have been developed in the recent past, there is no standard that concretely defines a specific sequence of steps to obtain a functional software system from a model. Thus, the existing approaches present numerous differences among themselves, because each one handles the problems inherent to software development in its own way. This paper presents and discusses a reference model for the comparative study of current MDE approaches in the scope of web-application development. This reference model focuses on relevant aspects such as modeling language scope (domain, business-logic, user-interface), usage of patterns, separation of concerns, model transformations, tool support, and deployment details like web-platform independence and traditional programming required. The ultimate goal of this paper is to determine the aspects that will be of greater importance in future web-oriented MDE languages.
Influence of Cold Storage on the Bioactivity Properties and the Quality of the Juice of Moro Blood Orange (Citrus sinensis (L.) Osbeck)  [PDF]

Abstract: The possibility of commercialization of Moro blood oranges in tropical countries such as Brazil was evaluated to verify whether post-harvest management through storage at low temperatures for a period of 60 days can improve the bioactive properties and quality parameters. Moro blood oranges cultivated in Brazil did not contain significant amounts of anthocyanins at the time of harvesting, but these compounds were activated by post-harvest management through storage at low temperatures (4°C and 8°C) for a period of 60 days. The emergence of the anthocyanins in the juices occurred within a few weeks of storage, but the maximum levels were attained after 60 days and at the temperature of 8°C. Cold storage positively influenced other bioactive compounds such as total phenolic compounds, individual phenolic compounds, β-carotene and the antioxidant activity determined by the sequestration of DPPH free radicals. It did not influence the vitamin C content. In addition, storage significantly altered the color, total

Abstract: previous studies have shown that color increases the production of responses to rorschach in adults but not in children. this increase is observed beginning from 15-16 years old. this developmental data, obtained from portuguese children and young individuals, led the authors to verify whether this property of color is innate or conditioned by neuropsychological development, whether it is learned or acquired. the application of rorschach in two groups of black children and young individuals from mozambique aged 12, 12 and 15 to 20 years following the same methodology indicated no essential differences in relation to the results obtained in lisbon, portugal. differences were pronounced in the second group for females, which raises issue of the phenomenon's cultural nature.
Mobilidade e acessibilidade no espa o urbano

Revista Sociedade & Natureza , 2005,
Abstract: This research aims at analyzing mobility and accessibility of public transit. People, who live in thesuburban sections and use the public transit means, have serious problems concerning the accessto the central areas of the city. Such problems come up with more intensity when there is bigpendulous migration (round trips). The low infrastructure of the sections together the population slow salaries cause serious mobility is linked to social-economical aspects of the population.Accessibility is related to land use and to the urban form, both of them involved in the city func-tional process.

Abstract: Death is a reality and a certainty for all, but in our society has become a taboo. This process occurred through the years with their transition from the family middle to the hospital context. In this new place new characters add themselves to meet and to face the experience of the death: the health professionals. This article aims to understand the perceptions and experiences of nursing students in front of the process of death and dying. The data collection was through a semi-structured interviews with students who attended the 8th Semester in a private institution on DF, 2010, the data collection happened after being approved by the Research Ethics Committee from the referred institution. The research was qualitative and whose six students testimonies were transcribed and analyzed based on content analysis, which ultimately resulted in four themes: I) Difficulty and denial of death; II) emotional management in the face of death and dying; III) Prepare for death and dying IV) Anxiety with the reality of future deaths. We conclude that graduating students feel unprepared to deal with death and dying process and tend to deny the situation. Besides, they point to the need for greater academic preparation about the subject in order to assist the individual self and acceptance.
