Sucessão estratigráfica e tratos de sistemas do Membro Romualdo, porção leste da Bacia do Araripe, nordeste do Brasil

Located in northeastern Brazil, the evolution of Araripe Basin has been associated with the fragmentation of Gondwana and opening of the South Atlantic. The Santana Formation belongs to the post-rift sequence of the basin and is characterized by the presence of laminated limestones in the lower portion (Mb. Crato), evaporite (Ipubi) and siliciclastics (Mb. Romualdo). For better understanding of the Romualdo's stratigraphy, depositional environments and tract of systems, a stratigraphic analysis was made with representative columnar sections of the unit. Sedimentary facies have been described in detail, as well as paleocurrents measured at different stratigraphic levels. It was found that the contact of Mb. Romualdo with the carbonate-evaporite section (Mbs. Crato and Ipubi) is a unconformity, evidenced by residual lags and thin layers of conglomerates above the contact. Above the conglomeratic levels predominate fine sandstones / medium interlayered with calciferous green shales. The percentage of shales increases towards the top, featuring retrogradational stacking culminating in layers of coquinas, excellent stratigraphic mark in the basin. Thin layers of coquins of gastropods comprising equinoids, located on the shale section, present in three sections marine deposits are associated with surfaces ravine. The upper section is characterized by recurrent facies of green shales, sandstones intercalated with sandstones progressively become more frequent towards the top of the unit, featuring the regressive part of the cycle. The sandstones present cross-stratification, often with mud clasts and clay layers in the foresets, and beddings of flaser type and wavy in heterolitic facies, suggesting the action of tidal currents. Paleocurrents measured in the sandstones show gaps with opposite flow directions outlining bipolar standards, which reinforce the interpretation of shallow marine environment influenced by tides during the sedimentation...

O sistema político, partidário e eleitoral da República de Malta

This work is a study which deals with political, electoral and party features from the Republic of Malta. An interest that motivated the study is to understand how works the consolidated two-party system in the country, the cleavages which foster that features and the Maltese media groups alignment process to those prevailing political parties. Our goal is to identify the main factors which creates and maintain those features of a two-party model in Malta, and how much it overlaps the political and electoral models applied in the country. The analysis is mostly literature, also backing up data about the nation, on elections and political parties which allow enough stability for analysis and enables us an approach about the actual facts. The survey data and literature available is mainly in English, by the lack of academic papers on Malta in Brazilian Portuguese. Therefore, this work contributes as a small panorama of the Maltese political reality, which can serve as a point of comparison and reflection on other countries' realities, with a sharp bipolar political trend, strong social entrenchment of political parties, and media groups aligned to those

Parcelamento de fontes alternativas de nitrogênio no milho safrinha em sucessão à soja

Increasing out-of-season corn productivity is possible by the application of nitrogen fertilizers even when in succession to soybean. On the other hand, information concerning the best sources of nitrogen and ways of splitting the doses to be applied is still scarce. Having that in mind, an experiment was carried out viewing to evaluate the effects of sources of nitrogen and ways of splitting doses of those N fertilizers on out-of-season corn sown in succession to soybean cultivated in a no-tillage system. The experiment took place in Chapadão do Céu, state of Goiás, Brasil (latitude of 18°35’42’’ South, longitude of 52°47’59’’ West and mean altitude above sea level of 802 m) in an Acrutox. The experimental units were distributed in the field in accordance with a randomized complete block design, in a factorial scheme 3 X 5 + 1, with four replications. Three were the sources of N: urea, urea extruded with starch (Amireia®) and ammonium sulfonitrate with a nitrification inhibitor (Entec®) and five the ways of splitting the nitrogen dose : 90-0, 60-30, 45-45, 30-60, and 0-90 in which the first fraction was applied at sowing and the second in side dressing. In addition to those, there was a check treatment, without N. All plots received, at sowing, 12 kg ha-1 of N by the mixture NPK. The ways of splitting the N dose and the sources of N had no significant effect on the levels of N and S in the leaves, first ear height, the final plant population, the number of ears per plant, and the number of grains per ear. N in the Entec® form at the highest doses applied in side dressing resulted in the highest grain yield, independently of the way the N dose was split. Only in the form Entec® the dose of 90 kg ha-1 of N increased grain productivity by 9.6% in comparison with the check treatment.

Fatores críticos de sucesso na implementação e gerenciamento do pensamento enxuto: um estudo na manufatura de fitas acrílicas

As a result of the industrial competitiveness increase in recent decades, concern about process improvements has been growing significantly. Lean Thinking principles are being more and more applied in the different sectors of the industry and aim to reduce costs, which can generate satisfactory results for an organization. Besides the application of lean tools on workstations, Lean Thinking seeks cultural change of the employees. Although the concepts of this management philosophy are widely disseminated, many organizations find barriers in their implementation and management. This study seeks to identify and evaluate the critical success factors in the implementation of Lean Thinking based on a qualitative research in the manufacturing environment of a multinational chemical company that produces acrylic tapes for the automotive market
