Estimation of water quality by UV/Vis spectrometry in the framework of treated wastewater reuse
Authors: Carré Erwan , Pérot Jean , Jauzein Vincent , Lin Liming , Lopez-Ferber Miguel
Published: April 2017

The aim of this study is to investigate the potential of ultraviolet/visible (UV/Vis) spectrometry as a complementary method for routine monitoring of reclaimed water production. Robustness of the models and compliance of their sensitivity with current quality limits are investigated. The following indicators are studied: total suspended solids (TSS), turbidity, chemical oxygen demand (COD) and nitrate. Partial least squares regression (PLSR) is used to find linear correlations between absorbances and indicators of interest. Artificial samples are made by simulating a sludge leak on the wastewater treatment plant and added to the original dataset, then divided into calibration and prediction datasets. The models are built on the calibration set, and then tested on the prediction set. The best models are developed with: PLSR for COD (Rpred2 = 0.80), TSS (Rpred2 = 0.86) and turbidity (Rpred2 = 0.96), and with a simple linear regression from absorbance at 208 nm (Rpred2 = 0.95) for nitrate concentration. The input of artificial data significantly enhances the robustness of the models. The sensitivity of the UV/Vis spectrometry monitoring system developed is compatible with quality requirements of reclaimed water production processes.

Published: April 2017

Achieving energy neutrality has shifted focus towards aeration system optimization, due to the high energy consumption of aeration processes in modern advanced wastewater treatment plants. A study on fine bubble diffuser fouling and mitigation, quantified by dynamic wet pressure (DWP), oxygen transfer efficiency and alpha was carried out in Blue Plains, Washington, DC. Four polyurethane fine bubble diffusers were installed in a pilot reactor column fed with high rate activated sludge from a full scale system. A mechanical cleaning method, reverse flexing (RF), was used to treat two diffusers (RF1, RF2), while two diffusers were kept as a control (i.e., no reverse flexing). There was a 45% increase in DWP of the control diffuser after 17 months of operation, an indication of fouling. RF treated diffusers (RF1 and RF2) did not show significant increase in DWP, and in comparison to the control diffuser prevented about 35% increase in DWP. Hence, reverse flexing potentially saves blower energy, by reducing the pressure burden on the air blower which increases blower energy requirement. However, no significant impact of the RF treatment in preventing a decrease in alpha-fouling (αF) of the fine pore diffusers, over time in operation was observed.
Fouling modeling of the mixed liquor in MBR by the individual and combined models
Authors: Hu Bo , Zuo Xingtao , Xiong Juan , Bao Ruiling , He Jiajie
Published: April 2017

To predict the membrane fouling phenomena in the membrane filtration operation, the individual models derived from Darcy's law and the corresponding combined models were employed to investigate the kind of models that provided better fits. The filtration of the mixed liquid from membrane bioreactors with different sludge retention time (SRT) at a constant pressure was carried out. The variation of applied pressure had significantly effect on the kind of the individual model provided better fit for the data at longer SRT and less effect for the data at shorter SRT, though it had less effect on the kind of the combined model that provided better fit. The kind of model that provided better fit did not change when the concentration of the diluted mixed liquor was at a certain range, even though the dilution ratio would lead to the variation of the prediction results. The cake-standard model and the complete-standard model provided good fits at different pressure and at different dilution ratio, respectively. The cake-standard and complete-standard models may be applicable to systems where these models are consistent with the experimentally observed fouling mechanisms.

Sustainability of Cultural Heritage in World Heritage Site, Melaka
Authors: Mohd Rodzi Nur Izzati , Ahmad Zaki Saniah , Syed Subli Syed Mohd Hassan
Published: April 2017

Cultural heritage is constructed from the intrinsic relationship between three fundamentals: society; tangible cultural heritage (TCH); and intangible cultural heritage (ICH). To sustain, cultural heritage relies on the social behaviour of society. Thus, reflecting fragility of heritage. Hence, this paper attempts to discourse the society’s behaviour towards ICH. Exploratory case study was employed by adapting five social behaviour related-criterions required by UNESCO. The data was analysed using two techniques: (1) simple statistical; and (2) thematic. The results indicate that the status of ICH is threatened due to the weak viability level and minimal safeguarding effort by the ‘society’.2398-4295 © 2016. The Authors.

Synergistic effects of para-hydroxy meta-methoxy chalcone (pHmMC)- doxorubicin treatments on T47D breast cancer cells
Authors: Arianingrum Retno , Sunarminingsih Retno , Meiyanto Edy , Mubarika Sofia
Published: April 2017

Resistance to some cancer chemotherapeutic drugs has been identifed. One strategy to overcome that problem is by combining two or more of the drugs to get co-chemotherapeutic effects. A derivate chalcone, 3 - (4’-hydroxy-3’-methoxyphenyl)-1-phenyl-2-propene-1-on or para hydroxy meta methoxy chalcone (pHmMC), has been reported to have cytotoxic activity on some cancer cells through some pathways. The aim of this study was to investigate the effects of combinations of pHmMC and Doxorubicin (Dox) on the cytotoxicity, anti-proliferation, apoptosis, and the cell cycle of T47D (breast cancer cell-lines) in vitro. The cytotoxic and antiproliferative activity were determined by MTT (3-[4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide] assay. The combination index (CI) was used to determine the synergistic, additive or antagonistic effects of the combinations. Flowcytometry method was performed to determine the combination effects on the apoptosis and cell cycle. The results indicated that the combinations had a higher inhibitory effect on the cell growth compared to those of single treatments of pHmMC and Dox. All the doses used in the combinations were lower of the single doses at their IC50s. The results showed all the combinations gave synergistic (CI: 0.3 – 0.7) up to strong synergistic (CI: 0.1 – 0.3) effects. The synergistic effects of the combinations were due to increased apoptosis and induced cell cycle arrest in S and G2/M phases on the cancer cell lines.

Pedagogias decoloniais e interculturalidade: desafios para uma agenda educacional antirracista
Authors: Miranda Claudia , Riasco Fanny Milena Quiñones
Published: April 2017

Esse trabalho se baseia em um constructo no qual a “decolonialidade” é a chave para a consolidação de outras visões sobre nossa autoformação e aprendizagens possíveis a partir das proposições que saem das configurações de resistência antirracista. Ganha centralidade as pedagogias decoloniais por fazerem parte de uma visão educacional emergente e que será mais bem compreendida quando alinhada aos estudos desenvolvidos no diálogo com os movimentos sociais na região conhecida como América latina. O intuito é discutirmos sobre as aprendizagens possíveis a partir do que nos é próprio. Apoiamo-nos em um amplo espectro de aportes que favoreceram o desentranhamento de um conjunto de saberes legitimados socialmente e que têm sustentado a crítica decolonial para propor outros modos de pertencimento. Sugerimos o enfrentamento de problemas relacionados com as diversas operações que facilitaram a configuração de um novo universo de relações intersubjetivas de dominação entre Europa e as demais regiões do mundo. Entendemos, com Catherine Walsh e Aníbal Quijano, que o pensamento decolonial assume o desafio de construir atalhos que inspiram a rebeldia e a desobediência por sugerir opções fronteiriças quando se trata de garantir a pluralidade, bem como outros lugares de conversa.

Institutional Groundings for Transformative Work with Students and in Schools
Authors: Foster Kevin Michael
Published: April 2017

Despite local, state and federal funding for compulsory education, educational opportunity is not evenly distributed in the United States. A range of challenges disproportionately face students of color and the poor and lead to uneven achievement outcomes. This essay uses the example of a specific universitybased institute to show how partnerships between universities, schools and communities can improve the likelihood of academic success among minority and impoverished populations. It further discusses an emergent theory of practice that can guide universitybased action-researchers who would hope to harness the resources of the academy and build partnerships that affect sustainable improvements in education. The article discusses purposefully constructing a seamless harmony between teaching, research and service among university faculty in order to facilitate research that directly and positively impacts local communities, generates knowledge, and facilitates the training and development of graduate students. It also argues that community-engaged work with underserved student and family populations includes both contextual and structural dimensions, and that careful attention to both may be necessary for achieving structural transformations that ensure that all students will be served well by their schools.
Currículo na Educação Infantil e as Ciências da Natureza: (Re)Educando para a Diversidade Étnico-Racial
Authors: Dias Lucimar Rosa , Reis Maria Clareth Gonçalves
Published: April 2017

Neste artigo, analisamos as propostas curriculares da educação infantil dos municípios do Rio de Janeiro-RJ e de Curitiba-PR, e os conhecimentos relacionados às ciências da natureza nelas previstos. Para essa reflexão, tomamos como referência teórica Gomes e Jesus (2013), Dias (2011), Kramer (2007), Silva Junior (2011), Reis (2010), Bento (2011), Silva (2009) e Tiriba (2010). Além dos(as) teórico(as), consideramos a Lei de Diretrizes e Bases da Educação e as Diretrizes Curriculares Nacionais da Educação Infantil (2009). Constatamos que, mesmo com mais de 10 anos da alteração da LDB e cinco anos da revisão das DCNEI, as propostas pedagógicas da educação infantil dessas capitais brasileiras não contemplam as proposições legais que recomendam a oferta de aprendizagem relativa às culturas afro-brasileira e africana. Com isso, apontamos a necessidade urgente de atualização desses documentos, ao mesmo tempo em que indicamos práticas pedagógicas a serem realizadas de imediato – a fim de garantir às crianças da educação infantil o direito ao conhecimento dessa área, tomando-a sob uma perspectiva plural e que contemple a história e cultura afro-brasileira e indígena. Dessa forma, as determinações legais serão cumpridas.

A Experiência Escolar nas Narrativas de Identidade Étnico-Racial: Estudo Retrospectivo de uma Professora Negra do Município de Juiz de Fora, MG
Authors: Talma Andressa Lima
Published: April 2017

Este artigo se baseia em minha dissertação de mestrado, na qual o objetivo foi compreender a trajetória de vida de uma professora negra que tem o trabalho reconhecido da rede municipal de educação de Juiz de Fora por valorizar o ensino étnico-racial. Utilizei-me da pesquisa narrativa para acompanhar a prática pedagógica da professora e sua trajetória. A pesquisa se apoiou na Antropologia do Imaginário, que busca o equilíbrio entre razão e emoção. Nesse sentido, o imaginário busca a compreensão de um segundo sentido das imagens. No decorrer da pesquisa, pude perceber nas narrativas iniciais da professora a valorização do elemento-ponte, que na perspectiva do imaginário faz a ligação dos contrários e é dessa forma que a professora realiza o seu trabalho. Faz uma ponte para que a cultura negra chegue até sua sala de aula. Ela embasa o seu trabalho em histórias de seus antepassados e no saber materno recebido. No entanto, algumas falhas em relação ao seu planejamento nos apontam a falta da formação acadêmica inicial e continuada para um aprimoramento do seu trabalho.

Como resultados de pesquisa evidenciamos os saberes experienciais compartilhados pelo supervisor durante sua ação, com destaque para os tipos mais presentes em sua comunicação: Planejamento dos Conteúdos de Aprendizagem; Planejamento das Atividades de Aprendizagem; Planejamento do Ambiente Educativo e Ensino Explícito.
Extended SAC: A Review on DC and SAC of 4-bit BFs and S-Boxes and a New Algorithm on DC of S-Boxes based on Various Types of SAC including the Extended Higher Order SAC
Authors: Dey Sankhanil , Ghosh Ranjan
Published: April 2017

Bitwise-Xor of two 4-bit patterns is the 4-bit difference between them which carries useful information in Cryptography. The method to analyze cryptographic ciphering algorithms or 4-bit Substitution boxes (S-boxes) with 4-bit differences is known as Differential Cryptanalysis (DC). An analysis of DC of 4-bit bijective Crypto S-boxes based on Differential Distribution Table (DDT) is reviewed including the Strict Avalanche Criteria (SAC) of 4-bit BFs and corresponding S-Boxes categorizing SAC in two orders, namely Simple Order (SO) and Higher Order (HO). A new algorithm of adding an extension of HO-SAC is proposed and considering the comprehensive SAC, which considers SO-SAC, HO-SAC and extended HO-SAC together, the properties of whole set of 65536 4-bit BFs including the comprehensive SAC are analyzed. Another new algorithm to analyze comprehensive SAC properties of 4-bit S-boxes is elaborated based on Differential Analysis Table (DAT) which turns out to be a better tool than DDT in analyzing DC of 4-bit S-boxes.
2-D Near Field Source Localization by Evolutionary Technique Exploiting the L-Type Geometry of Sensor Array
Authors: Sheikh Yawar Ali , Ye Zhongfu , Shabir Kashif , Mahmud Tarek Hasan Al , Ullah Rizwan
Published: April 2017

The efficiency of two dimensional (2-D) Direction of Arrival (DOA) estimation relies on the geometry of array. Among many array geometries, L-type array structure is becoming more popular among researchers because it can be decoupled into two uniform linear arrays (ULAs) and require less number of array elements as compared to other planar arrays. This paper propose a novel, fast and low complexity method for joint estimation of range and 2-D DOAs (elevation and azimuth) of near field sources. The main focus of this paper is to present the efficacy of performance and ease in implementation of L-type array structure when it is integrated with Differential Evolution (DE), a global evolutionary optimizer. To avoid the pair matching of estimated parameters, mean square error is used as fitness evaluation function as it only requires a single snapshot of array output to achieve optimal convergence. The robustness of proposed method is tested by a large number of computer simulations and statistical performance analysis is compared with other techniques.

Authors: Boyinbode Olutayo K. , Agbonifo Oluwatoyin C. , Ogundare Aderonke
Published: April 2017

With the proliferation of mobile devices, mobile learning has become a learning paradigm in education. The aim of this paper is to evaluate the media richness of various message delivery methods in mobile learning (m-learning) environment. This study evaluates media richness in respect to content timeliness, content richness, content accuracy and content adaptability in WhatsApp, Email, SMS, Twitter and BBM. One-way ANOVA analysis and Post hoc analysis show that: (i) SMS has better performance than WhatsApp, Email, Twitter and BBM on content timeliness; this implies that SMS may be more appropriate for delivering real-time information such as notifying or reminding of some time-sensitive matters, (ii) WhatsApp has better performance than Email, SMS, Twitter and BBM on content richness and so may be applied in information delivery that is rich in images and videos, (iii) WhatsApp has better performance than Email, SMS, Twitter and BBM on content accuracy and content adaptability. WhatsApp due to its media richness is more appropriate for supporting learning activities in a mobile learning environment. This study suggests that developers and designers of an m-learning environment could adopt WhatsApp as a suitable information delivery medium to support corresponding learning activities in a mobile learning environment.
Is Operational Control Risk Informative of Financial Reporting Deficiencies?
Authors: Lawrence Alastair , Minutti-Meza Miguel , Vyas Dushyantkumar
Published: April 2017

This study provides evidence concerning the significance of assessing operational control risk as part of an integrative evaluation of internal controls. We examine whether operational control risk indicators can be used as cues to potential unreported financial reporting control weaknesses and financial reporting deficiencies. We use data breaches and an operational control risk index, created through textual analysis of Form 10-Ks, as our two primary indicators of operational control risk. We find positive relations between our operational control risk indicators and future financial reporting control weaknesses, restatements, SEC comment letters, and audit fees, even after controlling for contemporaneous financial reporting control weaknesses. These findings suggest that operational control risk is informative of potential financial reporting deficiencies.

Each transect was 100 meters long and two meters wide, which were divided into ten segments (10 mx2 m), and laid perpendicular to the coast line started from the lowest tide level to the open sea. This study showed that average density of lola snail in Saparua Island is 620 individu/ha, with total biomass is 4.15 ton/ha. In Nolloth, lola snail have the highest density as well as the biomass, whilst in Ullath it shows the lowest density. The further down from the lowest tide level, the larger its shell diameter, and this relation can be expressed by y equal –2.118 plus 0.053x (r2 equal 0.879). Morisita dispersion index revealed that the distribution pattern of lola snail is clumped.

Lincat disease of temanggung tobacco could not be controlled effectively. One method of control which could be integrated with other measures is biological control. Bacillus is one of soil microorganisms which was not used widely as a biological control agent of plant disease. This report showed the results of the use of local isolates of Bacillus in controlling lincat disease of temanggung tobacco. As much as 91 isolates of Bacillus were directly tested in the field for their capability in suppressing lincat disease development. Six isolates, Ba-4, Ba-22, Ba-24, Ba-30, Ba-33, and Ba-41, could suppress lincat disease in the field. The result of in vitro test indicated that not all isolates which produced zone of inhibition in vitro could suppress disease development in the field. On the contrary, not all isolates which suppressed lincat disease in the field could inhibit the growth of pathogen in vitro. Isolate Ba-41, could suppressed lincat disease in the field and inhibited the growth of Meloidogyne incognita but not inhibited the growth of Ralstonia solanacearum.

Sambung nyawa (Gynura procumbens) has many beneficial effects to human health, such as decreasing blood pressure, maintaining blood sugar level (hypoglycaemic), decreasing cholesterol, a remedy for kidney trouble, antibacterial and lessen the inflamation (antiinflamation). This research was undertaken to discover the potency of endophytic microbes from sambung nyawa as antimicrobial agents. The purpose of this research was to screen the endophytic bacteria and the endophytic fungi having antimicrobial activity, which were isolated from stems, leaves, roots and fruits of medical plants, sambung nyawa. The antimicrobial activity was determined by measuring the growth inhibition of pathogenic microbes i.e Candida albicans, Escherichia coli, Pseudomonas sp. and Bacillus subtilis. A total of 38 isolates of bacteria and 15 isolates of fungi were obtained from sambung nyawa. Analysis demonstrated that, 45 percent isolates of bacteria and 20 percent isolates of fungi exhibited inhibitory activity. Antimicrobial activity was found in 21 percent of the isolates that inhibited the growth of C. albicans, E. coli, Pseudomonas sp., and B. subtilis, whereas 24 percent of isolates had activity only against B. subtilis. Isolate of endophytic bacteria USN 1.1 and USN 2.3 showed the most significant of inhibition zone. The Inhibition zone of the isolate USN 1.1 to C. albicans, E. coli, Pseudomonas sp, and B. subtilis were 2.318 cm2, 0.969 cm2, 0.796 cm2, and 0.381 cm2, respectively. The Inhibition zone of the isolate USN 2.3 to C. albicans, E. coli, Pseudomonas sp., and B. subtilis were 3.01 cm2, 0.519 cm2, 0.588 cm2 and 0.83 cm2, respectively. These results indicated that endophytic bacteria and endophytic fungi could be a promising source for antimicrobial agents.

Properties of soy protein hydrolysate produced by protease from biduri plant were studied. The soy protein hydrolysate had different properties due to various concentrations and hydrolysis times of protease from biduri. Enzymatic hydrolysis of the soy protein decreased significantly in the TBA value. This process increased the soluble protein content and promoted the Maillard reaction, resulting in a more brown color. Moreover, the soy protein hydrolysate had a higher value of umami taste by organoleptic evaluation.

Sugarcane is the principle plant for producing sugar in Indonesia. Water supply is one key element in the agronomy of sugarcane. Sugarcane is a high biomass crop which requires large amounts of water. Low yields of sugar observed in water stressed plants indicate that sugarcane is very sensititive to drought. A number of genes that respond to drought, salt, and cold stress at the trasnscriptional level have been reported. dip22 (drought inducible protein) protein isolated from drought resistance variety M 442-51 was predicted to be a protein regulator to water stress in sugarcane. Increasing of tolerance to water stress by over expression of dip22 genes in high yield sugarcane variety hopefully will maintain sugar production. The goal of this research was to construct a binary vector for dip22 gene expression in plant. dip22 gene from mutated PCR was cloned to pGEM®–T Easy and transformed to Escherichia coli strain DH5a. And then, these gene was isolated again from pGEM®–T Easy-dip22 (pGdip) plasmid using restriction enzymes NcoI and PmlI. pCAMBIA 1303 plasmid is an expression vector which has the constitutive promoter CaMV35S. Recombinant plasmid was transformed to Escherichia coli strain DH5a for plasmid propagation through DNA replication. Recombinant plasmid was isolated, and digested with NcoI and PmlI to examine the presence of dip22 gene in the pCAMBIA 1303 plasmid. The recombinant plasmid was transformed to A. tumefaciens strain LBA 4404. Plasmid isolated from A. tumefaciens was digested with Bst XI and Bst EII to examine the similarity between pCAMBIA 1303-dip22 (pCdip) from Escherichia coli and A. tumefaciens. The result by electrophoresis showed that both plasmids had the same size after digested. It was concluded that the transformed A. tumefaciens strain LBA 4404 bacteria has pCAMBIA 1303-dip22 (pCdip) plasmid indeed. Therefore, this construct of dip22 gene in binary vector can be used for improving drought tolerance in plant.

Research of the structure and development pattern of somatic embryos from callus of leaf explants moon orchid Phalaenopsis amabilis (L) Bl had been done. One year old of plantlets were used as explants sources. Basal leaf of these explants were cultured in Somatic Embryo Induction Medium (SEIM) e.i.: NP(New Phalaenopsis) medium added with 2 mg/L NAA, 1 mg/L BA, 10 g/L sucrose, and 2 g/L gellan gum. Then somatic embryos were transferred to EMM (Embryo Maturation Medium) e.i. NP medium added with 1 mg/L NAA, 1 mg/L BA, 10 g/L sucrose, and 2 g/L gellan gum. Finally, mature somatic embryo were transferred to NP medium without plant growth regulator as Embryo Germination Medium (EGM). The origin of somatic embryos initially from single cell at the pheriphery of embryogenic callus. These cells then devided in mitotic repeatedly formed globular proembryo, elongation embryo, and completed embryo. The structure and development pattern of somatic embryos as the same as with zygotic embryo.

In order to compare transient expression of gus gene driven by CaMV 35S and rice ubiquitin RUBQ2 promoters, a DNA transformation was conducted using embryogenic callus and suspension cultures of sugarcane. The transient gus expression was observed by histochemical staining method. The histochemical observation of GUS activity after co-cultivation showed that RUBQ2 promoter produced high level of clear blue spots both in embryogenic callus and suspension cultures, while the CaMV35S promoter was not detected. The suspension cultures slightly increased transient gus gene expression compared to embryogenic callus. However, the histochemical analysis of regenerated putative transformant plants after 5 successive cycles on the selection medium showed no blue spots of gus gene expression. PCR amplification of DNA for CaMV35 or nptII in putative transformant plants confirmed that there was no integration of the transformed gene in the genome DNA. The results suggested a possibility of somaclonal variation with callus propagation, thus did not produce transformed plants. To avoid the somaclonal variation, the transformation was conducted using in vitro plants and multiple shoots without intervening callus phase. Histochemical observation of infected materials after co-cultivation showed that almost all of the infected materials partially exhibited blue color in the basal region. In case of in vitro plants, they rapidly grow and multiplied in the selection medium, thus the method provided an excellent system for the transformation in sugarcane. The results suggest that in vitro plants as well as multiple shoots need further investigation to be used as target tissues for Agrobacteriummediated transformation in sugarcane.

Star apple or Chrysophyllum cainito L., family Sapotaceae; which is indigenous in Central America has been grown locally arround Jember, East Java. Ethnobotanical data exhibits its medicinal properties such as: soothing inflammation in laringitis and pneumonia, treatment for diabetes mellitus and cancer remedy which are related to free radical mechanism. Therefore, it is necessary to determine its free radical scavenger activity. There are three types of Jember’s star apple fruit (local name: kenitu): big size, green color with round shape (kenitu hijau bulat); medium size, green color with oval shape (kenitu hijau lonjong); and small size, red purplish color with round shape (kenitu merah bulat). Previous research shown that both water and methanol extracts of kenitu hijau lonjong has DPPH free radical scavenger activity as its antioxidant capacity. In recent research the DPPH free radical scavenger activity was performed on both water and methanol extract of these three types of kenitu. The results showed that kenitu merah bulat exhibits the highest antioxidant activity of these three types with IC50 426.118 and 169.094 ppm for methanol and water extracts sequentially in 60th minutes.
