title: Aptian/Albian (Early Cretaceous) paleogeography of the South Atlantic: a paleontological perspective

description: Paleontological data obtained in recent years reinforce the hypothesis that Aptian marine sedimentation in the sedimentary basins of the Brazilian continental margin - except the Pelotas basin, the southernmost Brazilian basin - took place under the domain of waters coming from the north through the Tethys Sea (Central Atlantic). Tethyan waters could reach the basins of the Brazilian continental margin via the seaway then existing in the present-day region of northeastern Brazil. Here there are records in several basins, notably in the São Luís (Codó Formation), Parnaíba (Codó Formation), Araripe (Santana Formation), Tucano (Marizal Formation), Sergipe (Riachuelo Formation) and Camamu (Algodões Formation) basins. Despite irrefutable marine evidence - e.g., dinoflagellates, echinoids, foraminifera, molluscs and fishes, conspicuously present in the Araripe Basin - there are very few paleogeographic reconstructions that include the seaway which is totally ignored in the international literature. The skepticism is even greater in relation to the Tethyan affinity although the evidence has been well documented by molluscs and dinoflagellates, together with ammonoids in the Sergipe Basin. That skepticism may be due to the fact that, in tectonic and geodynamic terms, the opening of the South Atlantic indeed proceeded from south to north, at least in the part that extends from Argentina to the northeastern Brazilian state of Paraíba.

title: Theorical analysis to explain the slow acceptance of the recent residential vertical trends in San José, Costa Rica

description: Abstract This article aims to evaluate the emergence and evolution of the Costa Rican real estate market in order to unravel the context of the strong bond with the land and hence the slow acceptance of new residential vertical trends. The methodology consists of annual fieldworks between 2011 and 2017, a revision of some local antique urban photographs and a bibliographical review of Costa Rican, Brazilian and international Marxist authors, with the purpose of formulating a theoretical discussion to show how changes in the modes of production and the local economy strengthened the relationship between people and their land. A broad time frame is analyzed, from the colonial period until nowadays, in order to examine, how across the course of the evolution of the real estate market, the different forms of housing have adapted to preserve the strong attachment that the population has had for their land. Afterward, the issue of the recent emergence of luxury vertical buildings is addressed and a semantic analysis is done to examine the population´s response to the new residential proposal without access to open space. It is concluded the strong attachment to the land may be one of the main reasons for the slow acceptance of new vertical developments in Costa Rica, even though there might exist other factors.

title: Overland flow generation mechanisms in the Concórdia River basin, in southern Brazil

description: ABSTRACT Overland flow in watersheds is responsible for the occurrence of various environmental problems, including flood formation, erosion and the transportation of sediment, and the addition of pollutants to the soil. Additionally, understanding this hydrological process is fundamental to improving knowledge regarding individual interest factors in a region, since it interferes with agricultural productivity and water supply for both the population and industry, among other contributions. Two principal theorists have described the overland flow generation processes: Horton (1933) and Dunne (1978). The TOPMODEL (a topography-based hydrological model) approach represents the overland flow by variable contribution areas, which develop along the watercourses following the concept of Dunne’s overland flow. Thus, this study aimed to evaluate the mechanisms of overland flow generated in the Concórdia River basin based on the application of the TOPMODEL, using measured hydrological data obtained from a high frequency installed monitoring network. Discharge data series were performed for three sub-basins: SF3 (29.74 km2), SF2 (5.81 km2), and SF1 (2.36 km2). In these sub-basins, the flood hydrograph were separated and its response conditions were verified in the TOPMODEL. Rainfall, discharge, and potential evapotranspiration data were used in an hourly scale for the three sub-basins. In general, the model showed adequate efficiency for the SF3 sub-basin; however, the SF2 and SF1 sub-basins showed distortion in its parameters, thereby delaying the simulated hydrograph in terms of time. Accordingly, the results corroborate the more frequent appearance of Dunnian overland flow in the SF3 sub-basin, where the topography is smoother and features large areas with a low slope, which serve as variable saturation areas. The SF2 and SF1 sub-basins present characteristics that strongly reflect Hortonian overland flow, with slopes in the topography that do not allow the frequent formation of variable contribution areas.

title: GROWTH AND NUTRIENT ACCUMULATION AND EXPORT IN A SHORT-DAY ONION

description: ABSTRACT New hybrid onions that are more productive are currently being cultivated. Information on growth and nutrient accumulation must thus be updated to assist in the refinement of existing recommendations, enabling the better exploitation of the productive potential of these new genotypes. We determined the growth of plants and the accumulation and export of nutrients of the short-day onion ‘Soberana’ established by direct seeding. The experimental design was a randomized block with four replicates and the treatments were evaluation times. Leaf number, tissue dry weight, nutrient accumulation, and the maximum daily rate of accumulation were evaluated throughout the growing cycle. The order of nutrient accumulation was (g plant-1) K (0.72) &gt; Ca (0.38) &gt; N (0.32) &gt; S (0.14) &gt; P (0.08) &gt; Mg (0.06) and (mg plant-1) Fe (2.26) &gt; Mn (1.43) &gt; Cu (0.93) &gt; Zn (0.91) &gt; B (0.85). Macronutrient demand was highest between 61 and 148 days after sowing (DAS), and micronutrient demand was highest between 70 and 148 DAS.

title: Maxillary complete denture rehabilitation of a patient with marked maxillomandibular discrepancy: a clinical case report

description: Dentistry is constantly concerned with enabling better living conditions for patients, as well as providing comfort so that functions such as chewing, speaking, and swallowing may be executed properly and esthetically satisfactory. In edentulous patients, many of these functions are lost, but can be restored by prosthodontics. Within this context, the present article seeks to report a clinical case in which a maxillary complete denture was made for a patient presenting with maxillomandibular discrepancy and marked maxillary prognathism.

title: Alternative mechanisms of charging for use of water resources in wastewater assimilation

description: ABSTRACT Nowadays in most hydrological basins in Brazil, the charging mechanism of water use for effluents assimilation in inland surface water bodies is based on the emitted organic load parameter quantified in terms of Biochemical Oxygen Demand (BOD). This method is insufficient given the broad variety and compositions of discharges. Therefore, the objectives of the study are to propose alternative charging mechanisms for the qualitative use of water resources, aiming to insert, beside BOD, other parameters as calculation criteria; and to evaluate the charging potential for the Doce River hydrological basin. Two methods were proposed: the Limiting Population Equivalent (LPE) and the Compromised/Committed Volume (CV). Five water quality parameters were established: Biochemical Oxygen Demand, Chemical Oxygen Demand, Total Suspended Solids, Ammonia Nitrogen, and Phosphorus. The proposed mechanisms contemplated, from a broader perspective, the real problem concerning water quality in the Doce River basin. Simulations showed that phosphorus was a problem of concern for managing water resources in the specific basin. The method of Limiting Population Equivalent was considered of easiest application and understanding by its users.

title: Spatial variation of metals and phosphorus in sediments of a river influenced by urbanization

description: ABSTRACT The suspended sediments are a special compartment that characterizes the effects of land use in the watershed. Such compartment is able to trap organic compounds as well as metals in general. Spatial variation of concentrations can be accounted for the land use, soil composition and pollution. In this work, we aimed to assess the spatial variation of metals and phosphorus concentration presented in suspended sediments collected in a river under urban occupation. Using time-integrated suspended sediment samplers, samples were collectec in three sites covering different levels of occupation: Almirante Tamandaré (P1) and two in Curitiba city (Tingui Park -P2 and Barigui Park - P3). The sampler was settled to be 20 cm below the water surface and it was removed after 30 days. Twelve samples were collected to examining the following elements Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, La, Mg, Mn, Na, Nb, Ni, P, Pb, Sc, Sn, Sr, Th, Ti, V, Y, Zn and Zr by ICP-OES. The first site is characterized with only 5.73% of urban area; meanwhile the site P3 has the highest urban area 54.06%. Among the twenty seven elements, nineteen showed a positive variation in concentration between collected sites, giving indication that an enrichment of metals along the river. The following elements showed positive variation: P (151.20%), La (117.98%), Cd (93.33%), Cr (71.43%), Na (68.75%), Ni (68.07%), Y (66.67%), Th (63.64%) and Zn (56.77%). Considering local reference values it is concluded that Cd, Cr, Ni, P, Y and Zn appear associated with urbanization increase in the basin; Co, Sc, Sn, Cu and Mn appear possibly associated with urbanization; Ba, La, Na, Pb and Sr show inconclusive behavior in relation with urban influence ; Al, Fe, Nb, Th, Ti, As, Ca, K, Mg, Zr and Va demonstrate not be associated with urbanization.

title: You reap what you sow, don’t you? Socio-environmental micro-realities transformed by tourism in São Miguel do Gostoso, Rio Grande do Norte, Brazil

description: Abstract This study investigates the tourist city of São Miguel do Gostoso, from the theoretical and methodological viewpoint of Micro-History. The proposal is to highlight how micro-realities construct outstanding narratives about the place. For the argumentative foundation Micro-History is presented. This is the methodological route for the research construction that gave rise to this study. The methodological course of construction of the research was based on direct participant observation using semi structured interviews and analysis of films In this article, we made use of a sample with 16 subjects, out of a universe with 52 participants, here represented by: owners of sailing boats schools or marinas; municipal government members; dwellers that are members of associations, NGOs and/or committees; religious representations, and dwellers representing local history. Therefore, our conclusions point to an inextricable relationship between culture and nature, perceived within the intrinsic relation of environment and participants’ lives, as well as the urgency to think over micro-realities, so that we can reflect on tourism and future developments.
