Decomposição da palhada de forrageiras em função da adubação nitrogenada após o consórcio com milho e produtividade da soja em sucessão

The objective of this study was to evaluate the straw decomposition of the Urochloa and Panicum after intercropped with corn and nitrogen fertilization, as well as, the agronomic performance of soybean in succession. The experiment was conducted in an Oxisol in Cerrado conditions under no-tillage eight years ago. After the corn harvest intercropped with grass and cutting of forage homogenization were applied N rates (0, 50, 100 and 200 kg ha-1 of N - urea source) in coverage. The plots consisted of Urochloa brizantha,Urochloa ruziziensis and Panicum maximum Tanzânia and Mombaça sown at the time of corn sowing and subplots composed by accumulated amounts of nitrogen applied in forage plants prior to the soybean cultivation (0, 250, 500 and 1000 kg ha-1 of N, after five cuts). The experimental design was a randomized block with four replications in a split plot. Soon after the last cut of the forage, proportionate amount of fresh mass of the species of each subplot was wrapped in nylon bags called Litter Bags, these being deposited in direct contact with the soil, to determine the time of decomposition of the dry mass during a period of 150 days. The nitrogen doses, as well as, the corn intercropped with forages (except with Mombaça) interfere similarly in the straw decomposition of forage and in the soybean yield in succession. All the consortiums of corn and nitrogen fertilization predecessors determined that, at 60 days after desiccation and cutting, still remained between 50 and 60% of the initial straw for no-tillage system.

Doses e épocas de aplicação de potássio na cultura da soja em sucessão a plantas de cobertura

Potassium (K) is the second nutrient that is required in larger amounts by soybean crop. With the use of high doses of that nutrient and increase of no-tillage areas in last years, some changes occurred in ways of this nutrient application, as well as the introduction of cover crops in the system for straw formation. Due those facts, the aim with this work was to study doses and times of potassium application for soybean sowed as succession for cover crops in no-tillage system, in a clayey Distrofic Red Latosol, in cerrado region. The experimental design was a randomized block with treatments arranged in 3x3x5 factorial scheme, with the following factors, cover crops: Pearl millet (Pennisetum glaucum) and Proso millet (Panicum miliaceum) and a control (fallow area), rates of K2O (0, 50 e 100 kg ha(-1)) and K2O application forms (100% in the cover crops; 100% at sowing of soybean; 100% in topdressing in soybean; 50% at sowing cover crops + 50% at soybean sowing; 50% at soybean sowing + 50% in topdressing in the soybean) with four replicates. The Pennisetum glaucum as soybean predecessor crop yields higher dry matter content than the Panicum miliaceum in a short period of time. In clay soil with high content of potassium there was no response to the applied potassium levels. Full doses of potassium maintenance fertilization can be applied in the predecessor cover crop, at sowing or topdressing in soybean crop.

As relações públicas e a responsabilidade social empresarial: um estudo de caso da Empresa Júnior de Relações Públicas da Unesp Bauru - RPjr

The various changes occurring in society in the late twentieth century created a context of true technological revolution based on information. These changes resulted in three points: a new way to communicate with the emergence of new media and communication platforms; a new role assigned to organizations increasingly blamed for social problems, and a greater access to information by society, which forms more critical and demanding. The convergence of these three consequences observed strengthening of the concept of Corporate Social Responsibility and the importance of internal communication in their construction. This literature review and empirical research, based on a case study with the Junior Enterprise of Public Relations at Unesp Bauru, studied the role of Public Relations in the process of communication management as a facilitator of internal processes towards mobilization for Social Responsibility. It intent to see which are the main barriers to the inclusion of the concept too. The study shows the relevant current context itself, in which the concern with the changing social scenario should be seen as opportunities for growth. The concept of Corporate Social Responsibility should be inserted into the organizational DNA to its consolidation, characterizing itself as a cultural and dependent matter of internal restructuring. The role of public relations in this context covers the management of communication and harmony of the interests of all public organization

Sucessão estratigráfica do Andar Alagoas na Serra do Tonã, Bacia do Tucano (BA)

STRATIGRAPHIC SUCCESSION OF ALAGOAS STAGE ON SERRA DO TONÃ, TUCANO BASIN (BAHIA). Located in northeast of Bahia, serra do Tonã is a NS elongated plateau that standsout in the flattened relief of Tucano Basin. The stratigraphic succession belongs to the Aptian post-rift sequence of this basin. Based on facies analysis, vertical stratigraphic profiles and satelite images interpretation, three stacked stratigraphic units were recognized: (1) lower carbonate unit, composed by laminated limestones and breccias, 5 m thick, correlated with Camadas Batateira of Arripe Basin; (2) intermediate siliciclastic unit, 100m thick and made of sandstones exhibiting finning upward cycles, overlaid by mudstones and sandstones wich sedimentary structures suggest action of tidal currents and (3) upper carbonate unit, composed by laminated limestones, 2-10 m thick, related with Santana Formation, that record lacustrine environment with possible marine influence. Paleocurrent analysis indicates proviniance from north and paleoflows towards south, similar to the Aptian fluvial facies of Araripe Basin, showing that both basins integrated the same continental paleodrainage

Análise crítica da implementação de sistema ERP à perspectiva da metodologia de gestão de projetos

Management information systems such as ERP can bring to businesses many competitive advantages. There is a great demand for systems projects to consulting firms that have knowledge to manage this particular type of project. However, the rate of system projects that cannot achieve success is very high. The methodology of Project Management, standardized by the Project Management Institute, is a globally recognized standard and used even in projects involving information technology. In the present study, was made a case study of an ERP system implementation project in a large company, by a consulting firm. From this analysis and on contributions from the literature, recommendations were proposed for the project management, in order to better direct the PMI methodology in large projects involving systems like ERP

Avaliação biogeográfica em área de progradação positiva em Ilha Comprida/SP: um estudo de sucessão ecológica

The city of Ilha Comprida, located on the Environmental Protection Area Cananéia-Iguape-Peruíbe (APA CIP) and Lagoon Estuary Complex of Iguape-Cananéia-Paranaguá, is located at the southern end of the coast of the state of São Paulo. Ilha Comprida is a progradational barrier consists predominantly of sandy sediments of the Quaternary Period. Bibliographic and cartographic surveys demonstrate a large amount of sediments in the last centuries, leading to the expansion of the island in hundreds of meters towards SW / NE. The island has been suffering intense morphological change in the northeast corner - NE, growing 35 meters per year. The objective of this study is to measure and analyze the floristic diversity found in its extreme NE, recent accumulation area of sediment, comparing the results with data obtained in equivalent segment, located on the edge SW, agradation preterit area. Given this reality, we chose to assess how the process of ecological succession respond to these dynamics. That is, if we think of ecological succession, NE end (latest) is assumed to possess plant species in the initial stage of succession as well as the SW portion. However, it is assumed certain differentiation between species in both areas, and less diversity in the first case (NE). Using the method of fixed installments adopted for similar quadrants, we attempted to measure and analyze the floristic diversity of the NE end and compare the data obtained in the field with those listed for the SW end. The results confirmed the hypothesis of the research, and prompted several questions that point to the need for further deepening research on this theme

Análise do crescimento das empresas de base tecnológica no Brasil

Technology-Based Firms (TBFs) are companies with intensive innovation dynamics based on technical competences, and for which high growth rates are expected. Nevertheless, even in developed countries, the evidence suggests that significantly high growth rates are more the exception than the rule. In Brazil, most studies on TBFs focus on factors that limit their success, such as managerial experience and capital availability. Based on extensive field research and on a reliable enterprise growth rate indicator, this article aims to evaluate the expansion of those firms, analyzing its relation to key elements such as degree of consolidation, market insertion, and public policy support. We found a growth rate which, although widely varied amongst firms, was significant and was not directly related to the amount of public policy support.
