Abstract: there are few researches about control of soil acidy and adsorption of heavy metals in no-till system (nts). the aim of this study was evaluate the cadmium (cd), nickel (ni), copper (cu) and zinc (zn) adsorption in a rhodic hapludox, clayey, without and with surface liming (4.5 t ha-1) under nts. the experiment was established in ponta grossa, pr, in 1998. after 10 years, soil samples were collected to adsorption study. doses of 0 to 180 mg l-1 of cd and ni, and of 0 to 180 mg l-1 of cu and zn were added, in competitive systems. after the equilibrium, the quantity of heavy metals was measured. surface liming increased soil ph in all studied layers, resulting in improve of cu, zn, cd and ni adsorptions, mostly in the superficial layer. moreover, surface liming changed dynamics of heavy metals in soil, being an efficient strategy to minimize environmental problems associate with cd, ni, cu and zn in nts.
Neural Network in Computer Vision for RoboCup Middle Size League  [PDF]
Paulo Rogério de Almeida Ribeiro, Gil Lopes, Fernando Ribeiro
Journal of Software Engineering and Applications (JSEA) , 2016, DOI: 10.4236/jsea.2016.97022
Abstract: Robot World Cup Initiative (RoboCup) is a worldwide competition proposed to advance research in robotics and artificial intelligence. It has a league called RoboCup soccer devoted for soccer robots, which is a challenge because robots are mobile, fully autonomous, multi-agents, and they play on a dynamic environment. Moreover, robots must recognize the game entities, which is a crucial task during a game. A camera is usually used as an input system to recognize ball, opponents, soccer field, and so on. These elements may be recognized applying some tools of computational intelligence, for example an artificial neural network. This paper describes the application of an artificial neural network on middle size robotic football league, where a multilayer perceptron neural network is trained with the backpropagation algorithm, to classify elements on the image. Each output neuron represents an entity and its output value depends on the current entity that is present on the image. The results show that an artificial neural network successfully classified the entities. They were recognized even when similar color entities were present on the image.
Oxcarbazepine and spasticity: further observations
Bittencourt, Paulo Rogério M.;
Arquivos de Neuro-Psiquiatria , 1988, DOI: 10.1590/S0004-282X1988000400008
Abstract: the previously described anti-spastic effect of oxcarbazepine and 10,11-dihydro-10-hydroxycarbamazepine was found accidentally in 2 patients undergoing a double-blind comparative study lor evaluation of antiepileptic effect. in this study oxcarbazepine was given orally in doses of 300-2700 mg daily to one patient with transverse myelitis and to two patients with multiple sclerosis, all of whom had clinically disabling spasticity in the form of difficulty in walking, lower limb rigidity, spastic contractions of the lower limbs and ankle clonus. anti-spastic effect was observed at doses between 600-1200 mg daily and consisted in a substantial decrease in the above symptoms of spasticity. the anti-spastic effect appears at a dose immediately below that which produces nausea, dizziness and somnolence.

Analysis of the recent literature on air transportation emissions taxation [paper in Portuguese]
Paulo Rogério Perez Silva
Journal of Transport Literature , 2011,
Abstract: The researchers Jan K. Brueckner from Department of Economics, University of California and Anming Zhang from University of British Columbia have published a recent paper about the airline CO2 emissions charges on the increase in the price of fuel and its effects on airfares, airline service quality and aircraft design features. They also analyzed the impact of such increase in the price of fuel in the network structure. Their results show that emission charges will raise fares, reduce flight frequency, increase load factors, and raise aircraft fuel efficiency, while having no effect on aircraft size. Regarding the network structure, their conclusion is hub-and-spoke (HS) uses larger aircraft, more efficient aircraft fuel consumption and more flight frequency than fully-connected (FC) but do not identify which is the ideal network structure.
Comments on a study of the impacts of antitrust immunity in the USA [paper in Portuguese]
Paulo Rogério Perez Silva
Journal of Transport Literature , 2009,
Abstract: The present paper performs a review of Rene Kamita′s 2008 paper "Analyzing the Effects of Temporary Antitrust Immunity: The Aloha-Hawaiian Immunity Agreement". The author investigates the impact of an agreement between two local airlines under antitrust immunity to coordinate air travel capacity between December 2002 and October 2003. Using data from the Department of Transportation's Origin and Destination database the paper not only identified an steady increase in airline tickets during the mentioned period but also showed the prices persist well beyond the period of antitrust immunity. Just after a new entrant took part in this duopoly the airline tickets starting to go down. Rather than a competitive equilibrium the agreement generated a market with high and attractive prices.

Abstract: this article aims at analyzing and discussing the pedagogical project of the licentiate course in english at the federal university of alagoas - maceió in relation to the meanings of literacies. considering that a written document reflects a socio-ideological position (chartier, 1999); that a project should not only function pedagogically, but also politically in the sense that it should provoke a change in the reality (freire, 2001); and that the evolution of such a document depends on critical revisions (pennycook, 2001), we observed that this project, published in 2007, reveals a considerably restricted position in relation to the concurrent modalities and in relation to the modalities concurrent in the process of meaning-making (monte-mór, 2001) of these texts. the concept of literacy (in the singular) is restricted only to reading and writing and is apparently dissociated from the use of technologies.

Atividade de buprofezin sobre a cigarrinha verde do feijoeiro Empoasca kraemeri (Ross & Moore, 1957) (Hemiptera, Cicadellidae) em condi??es de laboratório
Moreno, Paulo Rogério;Nakano, Octávio;
Scientia Agricola , 2002, DOI: 10.1590/S0103-90162002000300011
Abstract: empoasca kraemeri is a key pest of dry beans (phaseolus vulgaris l.) in latin america and chemical control is necessary when the pest reaches high infestation levels (threshold). the objective of this work was to study the effect of buprofezin on first instars of empoasca kraemeri under laboratory conditions. this pest stage presented high susceptibility to the insecticide, with an estimated cl50 of 0.112 mg l-1. in another bioassay, virgin couples recently emerged were placed in contact with bean plants previously treated with buprofezin. the average longevities for females/males were: 46/27, 18/16 on treated plants with 10 and 50 mg l-1 of buprofezin, respectively, and 16/14 days on untreated plants. an average of 120 eggs / female was observed on untreated plants and 0.9 and 0.1 eggs/female on plants treated with 10 and 50 mg l-1 of buprofezin, respectively. the egg-laying frequencies, that determinates insect longevity, were: 2.31 on check plots and 0.09 and 0.01 eggs/female/day for treatments of 10 and 50 mg l-1 of buprofezin, respectively. in the last experiment, the effect of buprofezin on adults was investigated. males or females were kept in contact with leaves treated with 1,000 mg l-1 of buprofezin and then placed in contact with the opposite sex not treated with the insecticide. the average longevity observed for females and males was: 46/27 days on the untreated and 35/23 and 27/13 days for treated individuals kept in contact with buprofezin, respectively. differences among treatments were not observed on egg-laying frequency: 2.31, 2.56 and 2.42 eggs/female/day, on check, treated females and males with buprofezin, respectively.
