Application of several data-driven techniques to predict a standardized precipitation index
Authors: Choubin Bahram , Malekian Arash , Gloshan Mohammad
Published: August 2016

Climate modeling and prediction is important in water resources management, especially in arid and semi-arid regions that frequently suffer further from water shortages. The Maharlu-Bakhtegan basin, with an area of 31 000 km2 is a semi-arid and arid region located in southwestern Iran. Therefore, precipitation and water shortage in this area have many problems. This study presents a drought index modeling approach based on large-scale climate indices by using the adaptive neuro-fuzzy inference system (ANFIS), the M5P model tree and the multilayer perceptron (MLP). First, most of the climate signals were determined from 25 climate signals using factor analysis, and subsequently, the standardized precipitation index (SPI) was predicted one to 12 months in advance with ANFIS, the M5P model tree and MLP. The evaluation of the models performance by error parameters and Taylor diagrams demonstrated that performance of the MLP is better than the other models. The results also revealed that the accuracy of prediction increased considerably by using climate indices of the previous month (t – 1) (RMSE = 0.802, ME = –0.002 and PBIAS = –0.47).

Published: August 2016

Statistical models for surface-atmosphere energy balance components (net radiation, sensible heat, and soil-stored heat) as functions of global radiation are proposed. This study was carried out during three seasons (winter, spring, and summer) in Mexicali, an arid city of northwest México, by means of representative measurement campaigns of three types of land use in the study zone: urban, rural (desert), and farmed suburban. The hysteresis pattern in the proposed models between the global radiation and net radiation was found during summer at suburban and urban sites, which seems to be originated by atmospheric moisture introduced by artificial irrigation and the thermal inertia of land cover. The coefficient of determination (R2) and the mean square error are used as indicators of the quality of models.

Published: August 2016

The purpose of this study is to select a number of stations from the existing Sistema de Monitoreo Atmosférico (Atmospheric Monitoring System, SIMAT) of Mexico City to serve as an equivalent to the Photochemical Assessment Monitoring Stations according to the US-EPA criteria, in order to improve the study of urban ozone occurrence. The results indicate that four existing SIMAT stations meet the criteria to form such network. The relevance of this study is to present an ozone precursors monitoring network with continuous measurements for future trustful studies on air quality for ozone, considering the atmospheric chemistry and photochemical modeling for the design control strategies appropriate for the particular conditions of Mexico City.

Authors: Wallace Eric , Klinge Derek , Chesky Kris
Published: August 2016

The trombone is a popular, versatile, and unique member of the brass family of musical instruments. Yet the musculoskeletal health concerns of trombonists are grossly understudied. The purpose of this study was to develop and apply a novel online research strategy for assessing musical
and non-musical demographics along with prevalence, frequency, intensity, quality, timing, and location of site-specific trombone-related pain. Of the 316 trombonist respondents to this open survey, 76.6% (n=242) experienced trombone-related pain in one or more sites over the past year. Lip
was the site with the highest prevalence rate for pain (23%). Selected pain sites were outlined in three primary clusters of musculoskeletal sites: 1) the lips and jaw region, 2) left upper extremity, and 3) back region. Over 35% (n=114) reported that trombone-related pain prevented playing
their instrument. Site-specific characteristics of pain suggest that future epidemiologic studies seek to better understand location-specific intensity, frequency, quality, and timing of pain. Such details will assist educators, performers, and clinicians understand, prevent, and treat musculoskeletal
problems associated with learning and performing musical instruments.

Simulation of the Impact of Fracturing-Fluid-Induced Formation Damage in Shale Gas Reservoirs
Authors: Farah N.. , Ding D. Y. , Wu Y. S.
Published: August 2016

The unconventional gas resources from tight and shale gas reservoirs have received great attention in the past decade and have become the focus of the petroleum industry. Shale gas reservoirs have specific characteristics, such as tight reservoir rock with nanodarcy permeability. Multistage hydraulic fracturing is required for such low-permeability reservoirs to create very complex fracture networks and therefore to connect effectively a huge reservoir volume to the wellbore. During hydraulic fracturing, an enormous amount of water is injected into the formation, where only 25–60% is reproduced during flowback and a long production period. A major concern with hydraulic fracturing is the water-blocking effect in tight formations caused by the high capillary pressure and the presence of water-sensitive clays. High water saturation in the invaded zone near the fracture face may reduce gas relative permeability greatly and may impede gas production.

In this paper, we consider the numerical techniques to simulate during hydraulic fracturing the water invasion or formation damage and its impact on the gas production in shale gas reservoirs. Two-phase-flow simulations are considered in a large stimulated reservoir volume (SRV) containing extremely low-permeability tight matrix and multiscale fracture networks including primary hydraulic fractures, induced secondary fractures, and natural fractures.

To simulate the water-blocking phenomenon, it is usually required to explicitly discretize the fracture network and use very fine meshes around the fractures. On the one hand, the commonly used single-porosity model is not suitable for this kind of problem, because a large number of gridblocks is required to simulate the fracture network and fracture–matrix interaction. On the other hand, a dual-porosity (DP) model may also be not applicable, because of the long transient duration with large block sizes of ultralow-permeability matrix. In this paper, we study the applicability of the MINC (multiple interacting continuum) method, and use a hybrid approach between matrix and fractures to correctly simulate the fracturing-fluid invasion and its backflow during hydraulic fracturing. This approach allows us to quantify the fracturing water invasion and its formation-damage effect in the whole SRV.
Ethane-Based Enhanced Oil Recovery: An Innovative and Profitable Enhanced-Oil-Recovery Opportunity for a Low-Price Environment

Published: August 2016

This paper summarizes the current state of the ethane industry in the United States (US) and explores the opportunity for using ethane for enhanced oil recovery (EOR). We show both simulation data and field examples to demonstrate that ethane is an excellent EOR injectant.

After decades of research and field application, the use of carbon dioxide (CO2) as an EOR injectant has proved to be very successful. However, there are limited supplies of low-cost CO2 available, and there are also significant drawbacks, especially corrosion, involving its use. The rich gases and volatile oils developed by horizontal drilling and fracturing in the shale reservoirs have brought about an enormous increase in ethane production. Ethane prices have dropped substantially. In the US, ethane is no longer priced as a petrochemical feedstock, but is priced as a fuel. Also, substantial quantities of ethane are currently being flared.

Ethane-based EOR can supplement the very successful CO2-based EOR industry in the US. There simply is not enough low-cost CO2 available to undertake all the potential gas EOR projects in the US. The current abundance of low-cost ethane presents a significant opportunity to add new gas EOR projects. The ethane-based EOR opportunity can be summarized as follows:

CO2-based EOR works well, and is well-understood. Ethane has more solubility in oil, lower minimum miscibility pressures (MMPs), and better solvent efficiency than CO2. Ethane is operationally simpler than CO2 for EOR. Ethane is now inexpensive, and will likely stay inexpensive. Ethane-based EOR has become a viable option in the Lower 48 (lower 48 states in US). Large volumes of low-cost ethane are available. Recent additions to the growing ethane infrastructure now deliver ethane to locations where ethane-based EOR targets are plentiful.

Information and communication technology as a primary tool for Sefako Makgatho Health Sciences University’s statistics and operations research business
Authors: Matshonisa Seeletse Solly
Published: August 2016

The Department of Statistics and Operations Reasearch (SOR) at the Sefako Makgatho Health Sciences University (SMU) in South Africa desires to increase its research output, as well as to provide high quality teaching and learning. Most SOR lecturers want to embrace technology and innovations, and also be competitive both regionally and globally. This can be achieved more effectively if they are trained in computer applications. Thus, they should be developed into critical citizens of the digital world. They should also be prepared to use information and communication technology (ICT) as a teaching and learning resource, as well as a research and community engagement backing. An innovation in academia should be backed by the lecturer. Thus, the main concern of this paper is to explore use of ICT as a business tool in SOR. Methodologies of the study were case study and thematic content analysis, and the data collection tool was a questionnaire. The study found that SOR was understaffed and could not provide full statistics (stats) training mainly in the statistical packages. The lecturers were all trained in ICT and the packages. They were all willing to use ICT in SOR activities. The computer laboratories were adequate for the student numbers at the time, even though some computers were not working. These laboratories showed to be poorly adequate for the envisaged growth of SOR. SOR would also need more lecturers for the future growth. The study recommends growth of SOR in lecturers and ICT facilities, at the least
Treatment of oilfield produced water with electrocoagulation: improving the process performance by using pulse current
Authors: Zheng Tao
Published: August 2016

The main aim of this study is to investigate the technical and economic feasibility of the pulse electrocoagulation (PE) process on the treatment of oilfield alkali/surfactant/polymer flooding produced water. By using an Fe electrode, the performance of the PE process was analyzed in terms of operating parameters such as pulse duty cycle, current density, pulse frequency, electrode distance, and reaction time with removal efficiencies, some of which are presented in figures and others are given in tables due to the numbers of parameters. Under the optimal conditions of a pulse duty cycle of 0.3, current density of 35 mA/cm2, pulse frequency of 3.0 kHz, electrode distance of 1.0 cm, and reaction time of 40 min, the removal efficiencies of chemical oxygen demand (COD), oils and greases, turbidity, total suspended solids, and polyacrylamide reach 98.3, 99.0, 98.8, 98.1 and 94.3%, respectively, with an energy consumption of 0.19 kWh/kg CODremoved and an electrode consumption of 3.1 kg Fe/kg CODremoved. The quality of the final effluent could satisfy the requirement of the national discharge standard. Compared with the traditional direct current method, the PE process could save 76% of the energy. Moreover, the treatment performance of PE is much better than traditional chemical coagulation treatment using polymeric ferric sulfate.

Published: August 2016

This article aims to evaluate membrane contactors capability to remove and recover ammonia from landfill leachate (LFL). A hydrophobic hollow fiber membrane module was used to achieve such purpose. A sulfuric acid diluted solution was used as extraction solution to speed up ammonia content removal. Several factors that have influence on ammonia removal and recovery capability such as ammonia solution pH, concentration of sulfuric acid solutions and flow rate of liquid phases have been examined. Microfiltration was the method used as pretreatment. The results have shown that membrane contactor operated with LFL (pH 10), 0.1 M acid solution and liquid flow rate up to 0.5 L min−1 achieved 99.9% of ammonia removal, which corresponds to 79.1% of ammonia recovery from the extraction solution, and it is capable to produce highly purified ammonium sulfate solutions (41.2%, wt wt−1) to be used as fertilizer. The concentration of total ammonia nitrogen (TAN) in the residual LFL complies with Brazilian law requirements of 20.0 mg L−1 of TAN, regarding the disposal of effluents.

Authors: Farrokhi Mehrdad , Mahdavianpour Mostafa , Shirzad-Siboni Mehdi , Naimi-Joubani Mohammad , Jamali Hamzeh Ali
Published: August 2016

Variation in hospital wastewater (HWW) pollutants and differences with municipal wastewater (MWW), make the use of biokinetic coefficients obtained from activated sludge in the MWW treatment unprofitable for designing, modeling and evaluation of biological processes for HWW treatment. Since this study was conducted to evaluate the performance and biokinetic coefficients of a fixed bed bioreactor (FBBR) using rice husks as fixed media in HWW treatment, a new modified method was also proposed for biokinetic estimation in FBBR processes. For these purposes, five hydraulic retention times along with five sludge retention times were introduced to a pilot setup and the required data were attained. The performance process for chemical oxygen demand (COD) removal was significant (87.8–97.5%) in different conditions. The values of biokinetic coefficients k, Ks, Y and Kd were obtained as 2.42 (day−1), 55.5 (mgCOD/L), 0.2929 (mgBiomass/mgCOD) and 0.0164 (day−1), respectively. The rice husks with high surface area and high affinity for biomass accumulation on its surface are promising media for a green and environmentally friendly FBBR process. The kinetics parameters values are utilizable for modeling of FBBR using rice husks as fixed media in HWW treatment.
QUILOMBOS E DEMARCADORES DE IDENTIDADES ANÁLISE SUCINTA DE TRÊS CASOS NO ESTADO DO ESPÍRITO SANTO
Authors: Oliveira Osvaldo Martins de
Published: August 2016

Este artigo é resultado de pesquisas etnográficas em desenvolvimento com comunidades quilombolas no estado do Espírito Santo que tomam o jongo e o caxambu como referência cultural para demarcarem suas identidades. Além de uma breve abordagem teórica sobre etnicidade e memória, também passo de forma sucinta em algumas referências bibliográficas sobre quilombos, territórios negros e jongos, para depois analisar três casos etnográficos no Espírito Santo. Analiso, a partir de dados de pesquisas, a relação entre comunidades quilombolas e as culturas de jongos e caxambus, e concluo que tais práticas culturais tornaram-se referenciais da identidade dessas comunidades, pois os processos e contextos sociais nos quais sempre estiveram envolvidas levaram-na a desencadearem a transmissão de saberes e tomada de consciência sobre sua própria existência e sobre seus direitos. Essa consciência do ser quilombola é múltipla e dinâmica, ocasionando diferentes modos de apropriação comunitária dos saberes e práticas culturais herdadas para demarcarem seus territórios e identidades étnicas.
PROCESSOS IDENTITÁRIOS E A COMUNIDADE QUILOMBOLA LUZIENSE
Authors: Marcon Frank , Bomfim Welington
Published: August 2016

Neste artigo, a partir de uma pesquisa etnográfica concluída há seis anos, oriunda de uma demanda para elaboração de um relatório antropológico sobre a Comunidade Quilombola Luziense, analisamos a relação existente entre o tema das identidades e as experiências sociais desta comunidade como construção permanente e contínua de alteridade. Procuramos destacar os processos constitutivos de identificação, percebendo a relação entre memória, solidariedade, “fazer”, território e os sensos de coletividade tradicionais. A emergência normativa do direito quilombola, nos últimos anos, materializou um sentimento latente de identificação coletiva advindo de séculos de escravismo e que se reproduziu no longo processo de continuidade de desigualdades não superadas no pós-escravidão. Tais desigualdades nos remetem a necessidade de percebermos as distintas formas de imaginar o trabalho, a liberdade, a propriedade e o território por parte dos “Luzienses”, como formas de resistência e demarcadores das diferenças e das identidades que se materializaram no curso dos processos históricos na região Sul de Sergipe, implicados pelas relações de poder advindas do escravismo e do racismo.
HOMEM RAZÃO E MULHER EMOÇÃO: UMA ANÁLISE DA RELAÇÃO DICOTÔMICA ENTRE HOMENS E MULHERES NA VISÃO DOS ASSENTADOS(AS).
Authors: Martins-Suarez Fernanda Chiozzini , Sousa Júnia Marise Matos
Published: August 2016

RESUMO O presente artigo convida o leitor a uma reflexão sobre o pensamento dual que caracteriza o caráter hierárquico da inter-relação homem/mulher a partir de palavras que dão significados ao que se compreende pelos termos que definem os dois sexos. Os vocábulos aqui referidos são aqueles que representam ideias opostas, não só no sentido léxico, mas também no que concerne a interpretação social dos atributos que definem homens e mulheres sustentados pela relação dicotômica existente entre eles. O objetivo deste trabalho é investigar a origem e aplicação destas expressões dentro de uma abordagem histórica e sociológica. Para esta análise, então, foi considerada a associação de termos opostos como: racional, superior, forte e externo ao homem e, palavras como: emocional, fraco, inferior e oculto à mulher. Para isso, a definição de família patriarcal, baseada na família estruturada a partir do poder do homem culminando na “inferiorização” da mulher, também foi levada em conta, desde sua origem no ambiente rural até seu reflexo na esfera urbana. Apoiado nestas premissas e conceitos, o presente artigo baseia-se na metodologia de análise do conteúdo das respostas de assentados e assentadas de três projetos de assentamento (P.A.) localizados no estado de Sergipe a fim confrontar a teoria mencionada acima com as afirmações obtidas após categorização por sexo. Foram analisadas respostas dadas por homens e mulheres separadamente a partir dos dados coletados em uma pesquisa realizada no ano de 2009 e que resultou em tese de doutorado[1]. A intenção do artigo é buscar uma possível desconstrução da dualidade homem/mulher de caráter valorativo presente nas suas falas propondo ao leitor uma reflexão crítica sobre a prevalência do caráter “inferior” dado as mulheres, no sentido de desconstruir a relação emoção e inferioridade uma vez que este não é um dado biologicamente atribuído ao sexo feminino, mas sim, uma construção social. Palavras-chave: mulher, gênero, dominação, dualidade, assentamento [1]Os dados deste artigo fazem parte da pesquisa, que resultou na Tese de Doutorado intitulada: Do acampamento ao assentamento: uma análise da reforma agrária e qualidade de vida em Sergipe, defendida em 2009 no Departamento de Geografia da Universidade Federal do Sergipe.

ETNICIDADE E LUTAS SOCIAIS NO CAMPO NO BRASIL CONTEMPORÂNEO: UM ESTUDO DE CASO
Authors: Neves Paulo Sérgio da Costa
Published: August 2016

Nesse texto analisamos como os processos de autoreconhecimento de comunidades remanescentes de quilombos são influenciados e, ao mesmo tempo, estão influenciando as lutas sociais agrárias. O trabalho de campo foi realizado junto a uma comunidade do sertão do estado de Sergipe, região de forte presença do MST e de outros movimentos sociais agrários. Após diversos anos de lutas pela posse da terra, inclusive com a criação de uma associação de agricultores, o grupo reivindica o estatuto de comunidade remanescente de quilombos no início dos anos 2000 junto à Fundação Palmares, dando início assim a um processo, ainda em curso, de demarcação do território comunal. Para além do que essa experiência tem de semelhante com diversos outros casos no país, temos aqui um excelente exemplo empírico de como as ressignificações identitárias das comunidades de remanescentes quilombolas alimentam-se de memórias sociais marcadas por experiências de organização coletiva para obter a posse da terra. Em termos teóricos, isso significa rediscutir a emergência enquanto atores coletivos das comunidades negras rurais como uma tentativa de conciliação entre demandas por reconhecimento identitário e demandas por redistribuição de recursos econômicos. O que aproxima essa discussão de interessante debate sobre os critérios de justiça nas sociedades atuais por algumas correntes da filosofia política contemporânea, sobretudo no que diz respeito à complementaridade das demandas por reconhecimento com as demandas por redistribuição.

Authors: Agarwal Shalini , Saraswat Y. K. , Saraswat Vibhav K.
Published: August 2016

Present research work deals with the optical study of Zinc Oxide (ZnO) dispersed Polycarbonate/Polymethylmethacrylate (PC/PMMA) blend nanocomposites. ZnO nanoparticles have been prepared by simple chemical route and their average size has been confirmed by Transmission Electron Microscopy (TEM). The average particle size of the nanoparticles has been found to be ~11 nm. Formation of PC/PMMA blend nanocomposites has been confirmed by means of X-ray Diffraction (XRD). Absorption spectra, recorded using UV-Visible spectrophotometer, have been used to determine optical constants such as band gap, extinction coefficient, refractive index and real & imaginary part of dielectric constant. It has been found that band gap decreases as ZnO wt% increases in the blend nanocomposites. Lowest band gap has been found for PC25%/PMMA75% with ZnO 3 wt% blend nanocomposite. Increase in refractive index has also been found with increasing ZnO content. These types of blend nanocomposites have applications in UV-shielding and wave guide technologies.
