Abstract: RESUMé: La forte croissance des études humanistes-culturelles au monde, dans les dernières decennies, a provoquéune rennaissance d’une ancienne collaboration entre la géographie et la littérature. Cet essai introductoirea pour objectif recouvrer une des manifestations littéraires le plus proches de la géographie, c’est a dire,la “littérature de voyages, explorations et aventures”.Cette littérature a eu son apogée dans l’Europe du XIXème siècle, surtout en Allemagne, au Royaume-Uni et en France. Dans ce dernier pays, l’écrivain Jules Verne est le meilleur exemple de ce type delittérature, avec sa grande collection de Voyages extraordinaires. Le but de cet essai est d’analyser lesconnexions de cette collection littéraire avec la géographie.
Mapping of the Water Table Levels of Unconfined Aquifers Using Two Interpolation Methods  [PDF]
Oswaldo Augusto Filho, Wanessa Soares, Clemente Iriguay Fernandéz
Journal of Geographic Information System (JGIS) , 2016, DOI: 10.4236/jgis.2016.84040
Abstract: The spatial prediction of the water table can be used for many applications related to civil works (foundations, excavations) and other urban and environmental management activities. Deterministic and geostatistical interpolation methods were used to predict the spatial distribution of water table levels (unconfined aquifers) of important geological formations of the Joao Pessoa City (capital of Paraiba State, Brazil) with dense urban occupation and high demand for new civil works. The deterministic (topo to raster) and geostatistical (ordinary kriging) interpolation methods were evaluated using a Geographic Information System (GIS)-based investigation. The water table levels were obtained from 276 boring logs of Standard Penetration Test (SPT) in situ investigation distributed over the geological formations studied (an area of 59.8 km2, covering 40 districts of the Joao Pessoa City). The Nspt values and textural characterization data are stored for levels of 1 m depth. Some boreholes located in the area investigated were not included in the interpolation processes in order to be compared with estimated values (validation of the results). Maps of the water table depths were also produced to further analyze the quality of the water table surfaces interpolated by both methods. The phreatic surface interpolations provided satisfactory results for both methods (RMSE = 1.8 m). The topo to raster method showed a slight general tendency to be less affected by local values in relation to the kriging method and also has the advantage of integrating the drainage flow system, which is a relevant aspect for spatial models of the water table levels of unconfined aquifers. The ordinary kriging (geostatistical method) provides a prediction surface and some measure of the certainty or accuracy of the predictions.
Femoral Tunnels in Anatomical ACL Reconstruction: Techniques Inside Out X Outside In  [PDF]
Alexandre Pagotto Pacheco, Luiz Guilherme Hartmann, Roberto Freire da Mota e Albuquerque, Oswaldo Taglietta Filho
Open Journal of Orthopedics (OJO) , 2018, DOI: 10.4236/ojo.2018.810040
Abstract: Objective: To observe the accuracy and the advantages and disadvantages of the femoral tunnels made by the two techniques. Materials and Methods: We randomly summoned nineteen patients undergoing anatomic ACL reconstruction in a single band technique by the same surgeon: Ten by group II (GII) and nine by Group I (GI). GI: drilling in the technical in-out. GII: drilling the technique out-in. The patients underwent a CT scan with three-dimensional reconstruction of the distal femur. Was applied the technique of quadrants described by Bernard and Hertel and optimized for position by Forsythe and observed in the femoral tunnel: the accuracy of the joint entry; posterior cortical thickness in that point; emergency lateral distance to the lateral epicondyle and the overall length. Results: The coordinates of the distances obtained average was very close, with no statistical difference comparable to that obtained by Bernard and Hertel and Forsythe. The distance from the tunnel exit to the lateral epicondyle obtained average 1.46 cm in GI and 0.47 cm in GII, with a significant statistical difference. The thickness of the posterior cortex was 3.9 mm in GI and 5.4 mm in GII, with no statistical difference. The length averaged was 3.07 cm in GI and GII in 2.94 cm, with no statistical difference. Conclusions: Both techniques allow well placed tunnels, with no statistical difference. In the technique in-out the tunnel exit is closer to the lateral epicondyle. The thickness of the posterior cortex is similar. The length of the femoral tunnel is similar and around 3 cm.
Transposi??o e hidrelétricas: o desconhecido Vale do Ribeira (PR-SP)
Sevá Filho, A. Oswaldo;Kalinowski, Luciana Maria;
Estudos Avan?ados , 2012, DOI: 10.1590/S0103-40142012000100019
Abstract: the image of the ribeira do iguape basin is usually linked to environment protection, to the natural caverns and to the traditional people communities ("quilombolas", from the ancient slaves, the native indians, the fishermen). we draw here another diagnosis, lightening up important geo-economic issues, as the mining fields, the plantations and the hydraulic works. the main river has not yet been dammed for hydro - power plants, located in its tributaries, featuring an amount of 540 megawatt capacity. the more impressive one, named capivari - cachoeira system, built forty years ago, is based on a flow derivation from the high ribeira basin to the coastline of the paraná state. its consequences are negative down stream until the rivers pardo and ribeira, in the sao paulo state; and in the other side, it also affects far away the antonina bay. as these damages were not recognized during the licensing process of this power plant. we launch an alert about the environment degradation of this region, in the case if some other hydroelectric projects would achieve in the future.
Efeitos de radia??es gama do 60Co na conserva??o da semente do feijoeiro (Phaseolus vulgaris L.), variedade goiano precoce
Marcos Filho, Júlio;Godoy, Oswaldo P.;
Anais da Escola Superior de Agricultura Luiz de Queiroz , 1974, DOI: 10.1590/S0071-12761974000100010
Abstract: seeds of the field bean variety ?goiano precoce? (phaseolus vulgaris l.) were subjected to six gamma radiation dosages, comprising treatments from 0,0 to 6,4 krad. effect on seed germination was studied by means of factorial experiments conducted under laboratory controlled conditions. the factors used were radiation dosages and nine increasing lenghts of time from date of seed irradiation. seed vigor was determined by the rate of seedling emergence when planted in small field plots. a factorial design was used. the variables were the radiation dosages and six lenghts of time elapsed since date of seed irradiation. the following conclusions could be drawn from the results obtained: a) seed germination was adversely affected by all radiation dosages in relation to the check treatment. this effect however decreased significantly with storing time. b) seed vigor was higher for those treated with 0,4 krad, 0,8 krad and 1,6 krad when compared with those that were not irradiated. the 0,8 krad treatment was the most favorable.

Abstract: the combination of physical-chemical and biological processes in sanitary wastewater treatment has been employed as an alternative for phosphorus removal; however, one of its limitations is its large sludge production. this work aimed at evaluating the sludge production which resulted from iron salt application to different types of effluents, as well as studying the impacts of iron salt application on the physical-chemical characteristics of the studied effluents. it was concluded that the average sludge production values which resulted from ferric hydroxide formation were around 1.80, 1.95 and 1.34 mg sludge per mg of fe+3 ion, with regard to raw wastewater, aerobic treated effluent and anaerobic treated effluent, respectively, thus indicating that the liquid phase characteristics did not influence the ferric ion precipitation mechanisms.
