Reuso de água de drenagem subterrânea em canteiro de obras e para irrigação de ...
Sousa, Camila Mareco de; Silveira, Cleiton da Silva; Silva, Emerson Mariano da; Pontes, Roberto José Almeida deThe research consists of a case study with the construction site of a multifamily residential building located in the city of Fortaleza-Ceará. For this purpose, parameters of Consolidation Ordinance N° 5 (for drinking water), requirements of ABNT NBR 15900-1 / 2009, in the case of water interacting with cement, in addition to criteria established in Resolution CONAMA No 375, in the case of water for garden irri...
Indicadores de veranicos e de distribuição de chuva no Ceará e os impactos na a...
Rocha, Thaís Braga Carneiro; Júnior, Francisco das Chagas Vasconcelos; Silveira, Cleiton da Silva; Martins, Eduardo Sávio Passos RodriguesNortheastern Brazil has marked interannual rainfall variability with some dry and other rainy years. In this region, there are dry spells, which are consecutive days with no rainfall during the rainy season, causing losses in agricultural crops. This article aims to use an indicator of Indian summers already established by other authors 2020 and identify its relationship with the Rain Distribution Index and reg...
Análise da variabilidade espaço-temporal do SPI: um estudo de caso para a Sub-B...
Silva, Greicy Kelly da; Júnior, Antônio Duarte Marcos; Lima, Carlos Eduardo Sousa; Silva, Marx Vinicius Maciel da; Silveira, Cleiton da SilvaThis work has as objective to evaluate the spatiotemporal variability of the Standardized Index of Precipitation (SPI), in order to identify periods of water scarcity/excess in the Choró Sub-Basin in the State of Ceará. For this purpose, we worked with the historical series of rainfall data for the period from 1974 to 2018 and with the SPI on scales of 3, 6, 12, and 24 months. A pronounced inter-annual variabil...
Aproveitamento do RSU de Fortaleza em uma perspectiva de geração de energia
Freitas, Francisco Claúdio Costa de; Lira, Marcos Antônio Tavares; Silva, Emerson Mariano daThis work aims to analyze the current situation of the implantation of the plant of Renewable Natural Gas Fortaleza (GNR) Caucaia’s Sanitary Landfill in the state of Ceará. In order to comply with Law 12.305/2010 (National Solid Waste Policy - PNRS), which addresses the destination and treatment of waste, the concessionary company Marquise hired the company Eco Metano from the state of Bahia to "treat" the gas ...
Uma análise preliminar da distribuição espacial da climatologia de precipitação...
Silva, Emerson Mariano da; Castro, Marco Aurélio Holanda deThat study presents an analysis of the results of seasonal simulation of precipitation, in from February to May period, for years from 1971 to 2000, on region of the basins of the Ceará state, in semi-arid of the Northeast of Brazil (NEB), obtained through the application of downscaling dynamic technique (scale reduction of the forecast). The models of numeric forecast used in the study are: The Regional Spectr...
Análise das condições de instabilidade atmosférica associadas à ocorrência de u...
Silva, Emerson Mariano da; Silva, Vera Lúcia Cunha; Silva, Francisco Walber Ferreira daThis work presents atmospheric instability conditions associated to the occurrence of Mesoescale Convective System (MCS) in the metropolitan region of Fortaleza – CE, at 06/04/2002. The investigation is based in instability indexes (K, TT, LI) and Convective Available Potential Energy (CAPE). Radiossondes and Radar images were used in the investigation. The data were collected during the Experiment of Microphis...
Análise da climatologia de precipitação simuladaem escala regional usando downs...
Silva, Emerson Mariano da; Castro, Marco Aurélio Holanda deIt is presented the results of a evaluation to seasonal rainfall (February to May) in Northeast of Brazil simulating (1971-2000) to a Regional Spectral Model (RSM97) development at National Centers for Environmental Prediction (NCEP) nested in General Circulation Model (ECHAM4.5). The results show that the RSM presented good performance at simulated total rainfall average, in Northeast of Brazil. (NEB). Coeffic...
Caracterização da eletrodeposição de filmes finos de CdTe sobre Pt em meio ácido
Sousa, José Hugo de Aguiar; Maia Júnior, Paulo Herbert França; Silva, Álvaro Neuton de Araújo; Lima, Francisco MarconeThe electrodeposition has been used for obtaining semiconductor materials; however, remain unclear the mechanisms involved in this process. Thus, this paper presents the research of this process, showing the characterization of electrodeposited CdTe on platinum substrate in acid solution. The deposition occurs from 0.0 V relative to the electrode Ag/AgCl KClsat with step activated control and diffusion. The thi...
Sobre o sinal de um downscaling dinâmico às oscilações intrassazonais de precip...
Alves, José Maria Brabo; Souza, Everaldo Barreiros de; Costa, Alexandre Araújo; Martins, Eduardo Sávio Passos Rodrigues; Silva, Emerson Mariano daIntraseasonal oscillations are factors controlling the interannual variability of tropical rainfall. The knowledge of how numerical models reproduce its variability is important to better understand their roles and support operations of weather and climate. This paper investigates the sensitivity of a downscaling dynamic precipitation model in predicting the intraseasonal oscillations observed in the northern s...
Caracterização do regime de ventos no Piauí para o aproveitamento de energia eó...
Lira, Marcos Antonio Tavares; Moita Neto, José Machado; Loiola, João Victor Lopes de; Silva, Emerson Mariano da; Alves, José Maria BraboO presente estudo apresenta uma caracterização do regime de ventos em algumas regiões do estado do Piauí, realizada por meio da análise do perfil da velocidade média horária e mensal dos ventos bem como da freqüência da direção dos mesmos. O objetivo principal do trabalho é identificar possíveis sítios de geração de energia eólica no Piauí a partir do uso de uma ferramenta computacional: o software Windographer...
