Authors: Rahnamay Mohammad , Mahdavi Majid , Shekarchi Ali Akbar , Zare Payman , Hosseinpour Feizi Mohammad Ali
Published: August 2018

Anti-cancer activities of some pyrano-pyridines have been previously reported. Herein, we investigated anti-proliferative and apoptotic effects of the novel pyrano [3, 2-c] pyridine (P.P, TPM.P, 4-CP.P and 3-NP.P) compounds against MCF-7 breast cancer cells. The MCF-7 cells were cultured in the presence of various concentrations (20-200 μM) of the compounds for 3 days and the cell viability was determined by MTT assay. Induction of apoptosis was qualitatively assayed by acridine orange/ethidium bromide (AO/EtBr) staining, DNA fragmentation assay, as well as quantitatively by Annexin V/PI double staining and cell cycle analysis. These compounds inhibited growth and proliferation of the MCF-7 cells in a dose- and time-dependent manner. The IC50 values of P.P, TPM.P, 4-CP.P and 3-NP.P after 24 h of exposure were calculated 100 ±5.0, 180 ±6.0, 60 ±4.0 and 140 ±5.0 μM, respectively. 4-CP.P was determined as stronger compound and was chosen for further studies. The result of flow cytometric cell cycle analysis indicated an increase in sub-G1 population after 72 h treatment of the cells. Furthermore, it was accompanied with exposure of phosphatidylserine (PS) in the outer cell membrane after time course of treatment with the 4-CP.P. Based on these observations, the pyrano [3, 2-c] pyridines can be regarded as a valuable candidate for further pharmaceutical evaluations.Anti-cancer activities of some pyrano-pyridines have been previously reported.

A Case for Alpha-Lipoic Acid as an Alternative Treatment for Diabetic Polyneuropathy
Authors: Nguyen Ngoc , Takemoto Jody K
Published: August 2018

Purpose: The aim of this systematic review is to evaluate current evidence of alpha-lipoic acid (ALA) regarding efficacy, safety, and cost to accurately compare it with other diabetic polyneuropathy (DPN) treatments. The intention is to provide recommendations on future research and to promote utilization of ALA in the United States (US). Methods: A literature search was conducted on three databases: Scopus, PubMed, and Web of Science. The following criteria were used to select studies: (1) randomized controlled trials (RCTs) and open-label trials on ALA, (2) review articles and meta-analyses of RCTs on ALA, (3) study population consisting of patients with diabetes mellitus, peripheral neuropathic pain, and/or metabolic syndrome. Results: Twenty-five publications were selected including five RCTs and three open-label studies. Most clinical trials were conducted outside of the US. Current data provides evidence for the benefits of ALA in DPN treatment at a dose of 600 mg per day, either intravenously (IV) or orally, for a duration of at least 3 weeks with minimal side effects. Conclusions: ALA demonstrates effectiveness in treating DPN through multiple mechanisms to modulate pathophysiology and control symptoms. In addition, ALA exhibits activity in weight management and insulin sensitivity. The use of ALA for DPN in the US is worth considering because commonly prescribed medications have unclear mechanisms, more pronounced adverse effects, and are more expensive than ALA.  Further research needs to be conducted to assess long-term efficacy of ALA in US patients.

Rasuras e operações metalinguísticas: problematizações e avanços teóricos
Authors: Calil Eduardo , Felipeto Sônia Cristina
Published: August 2018

This work takes a linguistic discourse point of view to discuss the relations between metalinguistic operations and erasures in written texts of students in the classroom. This way, taking a conception of structure that supports la langue in this functioning – that is, assuming a subject that demands signification and another one that provides interpretation – and through what Lemos has been outlining in recent years (1996, 1999a, 1999b), we will analyze Fabre’s (1986, 1987) and Abaurre’s work (1996, 1997) which assume an enunciative theoretical perspective to consider that change in drafts points to an attitude of interrogation and adequacy from the writer.
Sentenças genericamente quantificadas e expressões de referência a espécies no português brasileiro
Authors: Müller Ana
Published: August 2018

This article investigates the expression of genericity in Brazilian Portuguese. Its theoretical background is the analysis of kind referring expressions as proper names of kinds (cf. Carlson 1977a, b, 1982) and of generically quantified sentences as sentences under the scope of a generic dyadic operator (cf. Carlson 1989 and Krifka et al. 1995). Two basic claims are made: (i) the canonic way of expression kind denotation in Brazilian Portuguese is the definite generic and (ii) the generic indefinite and the bare singular are only ‘normal’ indefinite phrases under the scope of a generic operator.

Som-silêncio em Concretion 1960, de Hans-Joachim Koellreutter
Authors: Irlandini Luigi Antonio
Published: August 2018

Concretion 1960 é o primeiro ensaio planimétrico de Hans-Joachim Koellreutter (1915-2005). Nele, o conceito de som-silêncio de Koellreutter está claramente realizado musicalmente. Neste artigo, explico este conceito e demonstro de que modo, e através de quais técnicas composicionais, Koellreutter chega a uma música na qual, em suas palavras, “o som é silêncio e o silêncio é som”. Com este objetivo, analiso a partitura da obra fazendo uso de definições e conceitos próprios do compositor, que se baseiam na sua estética relativista, numa visão da história da música como representativa de diferentes tipos de consciência, e em princípios da percepção gestáltica. A peça é uma mobile-form construída por unidades estruturais compostas de linhas e blocos sonoros que criam um devir estático, quiescente e diáfano, que propõe ao ouvinte uma escuta contemplativa e aquilo que o compositor chama de “experiência mítica” do silêncio como origem de todos os sons.

Rényi Entropy Power Inequalities via Normal Transport and Rotation
Authors: Rioul Olivier
Published: August 2018

Following a recent proof of Shannon's entropy power inequality (EPI), a comprehensive framework for deriving various EPIs for the Rényi entropy is presented that uses transport arguments from normal densities and a change of variable by rotation. Simple arguments are given to recover the previously known Rényi EPIs and derive new ones, by unifying a multiplicative form with constant c and a modification with exponent α of previous works. In particular, for log-concave densities, we obtain a simple transportation proof of a sharp varentropy bound.
Population Growth and Environmental Changes: Conclusions Drawn from the Contradictory Experiences of Developing Countries
Authors: Badesso Barana , Lachore Senbetie , Madalcho Aklilu
Published: August 2018

This review paper is intended to exhibit the interplays between environmental change and rapid population growth in developing countries. In the course of discussion, the impacts of rapidly population growing on the environment have been discussed, and evidence, from various parts of the world have been traced. Studies on the impacts of population pressure on environment have been critically reviewed. It is revealed that all across the developing countries, farm size is shrinking as farmers continue to subdivide holdings among their children. In countries such as Malawi, Rwanda, Ethiopia, Haiti, Nepal and Bangladesh, population growth rates are high, and the non-farm sector is still in its early stages of development. Demographic pressure, land scarcity, and land fragmentation drive greater rural vulnerability and poverty, marked by decreased food security, inadequate response to such natural disasters such as drought or pest infestations, weakened resilience to shocks, and poor health. It is not just the supply of food, fodder, and fuel wood but the resource base itself and the lives that depend upon it are being affected. The evidences pinpoints that man through his non-sustainable production and consumption patterns, is placed at the heart of environmental changes. However, contradictory view, and practices are also in place that the population growth has positive impacts environmental restoration and improvements, while other evidences show insignificant effect of population on the environment. This contradicting scenario puts scholars in argument, and still need further research. Hence, it would be a blind generalization to draw conclusion from this relationship alone, rather, another factor that acts beyond population pressure must also be considered to justify the impact of population on environmental changes.

Introduction-Electronic Cigarettes(E-cigarettes) was introduced into the market in 2007 as an alternative method for quitting smoking. Considering the global rise in the use of Electronic cigarettes, the study aims to perform the comprehensive review of literature on E -Cigarettes. Objectives-To explore the Presence and usage of E-cigarettes in India, to determine the Health -related issues due to the use of E- cigarettes globally, To compare conventional smoking modalities with E- cigarette usage globally, To assess whether use of E-Cigarettes can be helpful in reduction of behavior related to smoking cigarettes Methods -The Literature Search Strategy was developed using the key words based on the objectives and the electronic based data source for identification of papers was done in PubMed and Research Gate. The Study was Conducted from December 2017 to March 2018. Results -There are almost 75 companies which are supplying E-Cigarettes through online in India, and there is no brand in India which manufactures its own product except Evolve Vapors. Limited Studies assessing the health effects of E-cigarettes have been performed as most of them are done in the laboratory conditions. The use of E -Cigarettes were more in current smokers as the usage increasing in adolescents because of the modifiability and similarity with the Conventional Cigarettes. Randomized Control Trial(RCT) and Cohort Study were not able to generate enough evidence because of the Smaller no of participants in the study and lack of previous data available Conclusion-Well designed Newer Generation E -cigarettes trials must be monitored and measured for a longer period so that the Safety and efficacy of the device can be generated.
Extreme Learning Machines as Encoders for Sparse Reconstruction
Authors: Al-Mamun Abdullah , Lu Chen , Jayaraman Balaji
Published: August 2018

Reconstruction of fine-scale information from sparse data is often needed in practical fluid dynamics where the sensors are typically sparse and yet, one may need to learn the underlying flow structures or inform predictions through assimilation into data-driven models. Given that sparse reconstruction is inherently an ill-posed problem, the most successful approaches encode the physics into an underlying sparse basis space that spans the manifold to generate well-posedness. To achieve this, one commonly uses generic orthogonal Fourier basis or data specific proper orthogonal decomposition (POD) basis to reconstruct from sparse sensor information at chosen locations. Such a reconstruction problem is well-posed as long as the sensor locations are incoherent and can sample the key physical mechanisms. The resulting inverse problem is easily solved using $l_2$ minimization or if necessary, sparsity promoting $l_1$ minimization. Given the proliferation of machine learning and the need for robust reconstruction frameworks in the face of dynamically evolving flows, we explore in this study the suitability of non-orthogonal basis obtained from Extreme Learning Machine (ELM) auto-encoders for sparse reconstruction. In particular, we assess the interplay between sensor quantity and sensor placement for a given system dimension for accurate reconstruction of canonical fluid flows in comparison to POD-based reconstruction.

Published: August 2018

Laser-induced breakdown spectroscopy (LIBS) is an important analysis technique with applications in many industrial branches and fields of scientific research. Nowadays, the advantages of LIBS are impaired by the main drawback in the analysis of collected data. This procedure is essentially based on the comparison of lines present in the spectrum with a literature database. This paper proposes the use of various computational intelligence methods to develop a reliable and fast classification of non-destructively acquired LIBS spectra into a set of predefined classes. We focus on a specific problem of classification of paper-ink samples into 30 separate, predefined classes. For each of 30 classes (10 pens of each of 5 ink types combined with 10 sheets of 5 paper types plus empty pages) 100 LIBS spectra are collected. Four variants of preprocessing, seven classifiers (Decision trees, Random forest, k-Nearest Neighbour, Support Vector Machine, Probabilistic Neural Network, Multi-Layer Perceptron, and Generalized Regression Neural Network), 5-fold stratified cross-validation and test on an independent set (for methods evaluation) scenarios are employed. Our developed system yielded an accuracy of 99.08% with average classification time of about 0.12 s is obtained using the random forest classifier. Our results clearly demonstrates that machine learning methods can be used to identify the paper-ink samples based on LIBS reliably at a faster rate.

Published: August 2018

This study reports multivariate statistical techniques applied including cluster analysis to evaluate and classify the river pollution level in Taiwan, and principal component analysis-multiple linear regression (PCA-MLR) to identify the possible pollution source. Water quality and heavy metal monitoring data from Taiwan Environmental Protection Administration (EPA) was evaluated for 14 rivers in the four regions of Taiwan. The Erren River was classified as the most polluted River in Taiwan. Biochemical oxygen demand, ammonia, and total phosphate concentration in this river were the highest of the 14 rivers evaluated. In addition, heavy metal levels of the following rivers exceeded the Taiwan EPA standard limit: lead - in the Dongshan, Jhuoshuei, and Xinhuwei Rivers; copper - in the Dahan, Laojie, and Erren Rivers; and manganese - in all rivers. Water pollution in the Erren River was estimated to originate 72% from industrial sources, 16% from domestic black water, and 12% from natural sources and runoff from other tributaries. Our research showed that PCA-MLR and the cluster analysis model accomplished our study objectives and will be helpful tools to evaluate water quality in rivers and we suggest that the continuous monitoring should be conducted to monitor water pollution from anthropogenic activities.

Published: August 2018

The world is progressing towards a more advanced society where end-consumers have access to local renewable-based generation and advanced forms of information and technology. Hence, it is in a current state of transition between the traditional approach to power generation and distribution, where end-consumers of electricity have typically been inactive in their involvement with energy markets and a new approach that integrates their active participation. This new approach includes the use of distributed energy resources (DER) such as renewable-based generations and demand response (DR), which are being rapidly adopted by end-consumers, where incentives are strong. This paper presents the role of DR aggregator to effectively integrate DER technologies as a new source of energy capacity, into the electricity networks using information communication technology and industry knowledge. This framework based on DR aggregators will facilitate renewable energy integration and customer engagement in electricity market efficiently. To this aim, advantages and disadvantages of DR aggregators are discussed in this paper from political, economic, social and technological (PEST) point of views. Based on this analysis, a strengths, weaknesses, opportunities, and threats (SWOT) analysis for a typical DR aggregator is presented.

A Mixture Partial Credit Analysis of Math Anxiety
Authors: ÖLMEZ İbrahim Burak , COHEN Allan S.
Published: August 2018

The
purpose of this study was to investigate a new methodology for detection of
differences in middle grades students’ math anxiety. A mixture partial credit
model analysis was used to detect distinct latent classes based on
homogeneities in response patterns. The analysis detected two latent classes.
Students in Class 1 had less anxiety about apprehension
of math lessons and use of
mathematics in daily life, and more self-efficacy
for mathematics than students in Class 2. Students in both classes were
similar in terms of test and evaluation
anxiety. Moreover, students in Class 1 were found to be more successful in
mathematics, mostly like mathematics and mathematics teachers, and have better
educated mothers than students in Class 2. Manifest variables of gender,
attending private or public schools, and education levels of fathers did not
differ among the latent classes. Characterizing differences between members of
each latent class extends recent advances in measuring math anxiety.

Environmental impact assessment for a meat processing industry in Turkey: wastewater treatment plant
Authors: Yapıcıoğlu Pelin Soyertaş
Published: August 2018

The meat processing industry has many unfavorable impacts to the environment in Turkey. One of these impacts is wastewater treatment. Meat processing wastewater contains large amounts of proteins, fats, nutrients such as nitrogen, and pathogenic and non-pathogenic microorganisms and viruses. The high organic and hazardous content of wastewater causes environmental challenges for the flora and fauna in receiving water bodies unless it is treated adequately. Due to these reasons, the treatment process to be implemented should be the least damaging to the environment. In this study, three treatment scenarios that include a UASB (upflow anaerobic sludge bed) reactor (Scenario-1), an advanced oxidation process that includes UV/H2O2 treatment (Scenario-2) and a membrane bioreactor (Scenario-3) have been studied for a meat processor's wastewater treatment plant. For these three scenarios, an environmental impact assessment was undertaken using the Fine-Kinney method. The evaluation results revealed that Scenario-2 has the smallest environmental impact value with 475. Scenario-1 has the highest total environmental impact value as 765. Scenario-3's environmental impact value is 637. According to the evaluation results, the UV/H2O2 process is the most applicable technology for wastewater treatment in Turkey's meat industry.

This paper presents the design of a plant-wide CNP (carbon-nitrogen-phosphorus) simulation model of a full-scale wastewater treatment plant, which will be upgraded for tertiary treatment to achieve compliance with effluent total nitrogen (TN) and total phosphorus (TP) limit values. The plant-wide model of the existing plant was first designed and extensively validated under long-term dynamic operation. The most crucial step was a precise characterization of input wastewater that was performed by extending the plant performance indicators both to a water line and sludge line and systematically estimating identifiable wastewater characterization parameters from plant-wide performance indicators, i.e. effluent concentrations, biogas and sludge production, and sludge composition. The thus constructed simulation model with standard activated sludge model (ASM2d) and anaerobic digestion model (MantisAD) overpredicted ortho-P and ammonia-N on the sludge line, indicating a need to integrate state-of-the-art physico-chemical minerals precipitation models to simulate plant-wide interactions more precisely. The upgraded plant with multimode anaerobic/anoxic/oxic configuration shows limited denitrification potential. Therefore, additional reject water treatment was evaluated to improve effluent TN and TP performance.

Water and energy are resources that are dependent on each other. Water is needed for the production of energy for fuel extraction, cooling power plants, and processing of fossil fuels. In water cycles, energy is needed for pumping, treatment and distribution of water and wastewater to and from customers. In South Africa (SA), the energy used in the water industry is generated mostly from fossil fuels, which has a significant negative impact on the environment. This research reviews a representative subset of the SA water industry to evaluate energy efficiency and harmful gas emissions optimisation potential. The first component of this study involves a review of the current energy efficiency potential in water distribution systems in SA. On the basis of a literature review, three technologies/practices were identified as being imperative in optimising water utilities in SA. The second part of this study involves the implementation of some performance indicators that illustrate the interdependence of water loss, energy consumption and CO2, NOX and SOX emissions. These indicators are used to compare a few possible mitigation scenarios involving water loss reduction and increasing the system's energy efficiency. The third component of research is developing a novel multi-layered structural water distribution system model by incorporating 29 metrics extracted from the literature reviewed. Analysis of this model is then conducted using a MULTI-MOORA (Multi-Objective Optimization by Ratio Analysis) technique accompanied by a Triangular Fuzzy Number set. The aim of this was to assist water utility managers to identify the most influential performance indicators for attaining the nexus objectives.

The lamination process of aluminum sheets generates a flammable oil-soaked waste, which had been thermally treated (TTW) and used as adsorbent of reactive Remazol Black B (RB) and Remazol Red RB133 (RR), two of the most used dyes in the printing processes on textile industries, with reported carcinogenic and toxic properties. The adsorbent was characterized by Brunauer-Emmett-Teller (BET)-specific surface area, scanning electron microscopy and X-ray diffraction analysis. Kinetic and equilibrium studies were performed to evaluate the TTW adsorption parameters and the isotherm model which best represented the process. It was observed that the system reached the equilibrium state after 5 min for both dyes and obtained their maximum adsorption capacity (qm) at pH 4: 0.69 mg·g−1 and 2.89 mg·g−1, for RB and RR respectively; moreover, the pseudo-second-order model better fitted the adsorption kinetics. The equilibrium data were better fitted to Langmuir isotherm compared to Freundlich's for the RB and RR adsorption. The maximum removal efficiency obtained in the experiments was 80.2% for RB and 80% for RR; moreover, after the acid activation of TTW, the RB removal efficiency increased from 84.9% to 93.7%.
Application of multiple regression analysis in projecting the water demand for the City of Cape Town

Historically, the city of Cape Town has been affected by water shortages and it can be assumed that the situation will be exacerbated in the coming decades by a growing population, economic development and climatic changes as additional stress factors. In order to defuse the situation, the city of Cape Town has commissioned various feasibility studies concerning the implementation of alternative water sources, with as yet unpublished conclusions. Since sustainable water resource planning requires a comprehensive understanding of the water demand, the objective of this study was to predict the future demand by the city of Cape Town by analysing its significant drivers. For this purpose, a linear multiple regression analysis was applied on parameters which influence water demand, namely: population, economy, water losses and water restrictions. In order to establish the linear multiple regression model and its regression coefficients, historical data was used for the period 2001 to 2012. The result of the regression analysis showed that the water demand of the city of Cape Town is only decisively influenced by population and water losses. In addition, the model indicated that a new source would be required by 2021. Thus, water conservation and water supply strategies can be adapted accordingly to ultimately enable a sustainable management of the water sources in the city of Cape Town.

Authors: Melo Iran Ferreira de
Published: August 2018

Este texto relata parte da produção intelectual e metodológica de uma pesquisa vinculada ao subprojeto de pesquisa Gêneros jornalísticos impressos: historicidade, constituição e mudança em uma perspectiva crítico-discursiva que integra o projeto maior chamado História do Português Paulista da Universidade de São Paulo. Tal estudo consiste na análise de como homossexuais – lésbicas e gays –, bissexuais e pessoas transgêneras – travestis, transexuais e intersexuais – (LGBT), indivíduos historicamente excluídos de seus direitos sociais, são representados/as no jornal impresso de maior circulação do Brasil, a Folha de S. Paulo. O material que serviu de corpus ao trabalho foi composto por notícias sobre a realização do evento denominado Parada do Orgulho LGBT, ação coletiva organizada na cidade de São Paulo por pessoas que defendem a garantia da igualdade de direitos a LGBT. Trata-se de textos sobre todas as edições desse evento (1997-2012), publicados no dia e na data posterior em que ocorre. A partir da análise desses dados, a pesquisa propôs investigar o discurso produzido por meio das notícias. Concluímos que esse discurso revela um importante papel da Folha na produção de significados que afetam o modo como, em geral, a sociedade compreende o movimento.

Este trabalho tem como objetivo analisar a organização dos turnos e das sequências conversacionais em um evento de fala real. Para tanto, nosso corpus consiste na transcrição de material empírico coletado em situação de fala decorrente de um debate televisivo. Partimos das discussões feitas por Mello (1987), Duranti (2000), Heritage (1999), Sacks, Shegloff e Jefferson (2003 [1974]); Guesser (2003) e Marcuschi (1986), no campo da Antropologia Linguística e da Análise da Conversação. Os resultados revelaram que a interação entre os falantes foi organizada e reorganizada segundo o tópico conversacional, por meio de falas simultâneas, tomadas de turno e sobreposição de vozes, tendo como princípio as sequências pergunta-resposta, asserção-réplica, réplica-tréplica, estas últimas ocorridas pela despreferência dos falantes ao que foi dito no tópico conversacional. Com isso, foi possível compreender que em uma situação de fala cujos participantes tenham opiniões divergentes sobre o tópico conversacional, os turnos de fala serão amplamente disputados, ficando com a palavra aquele que insistir em continuar no turno.

Publicidade e racismo na ásia:o clareamento dermatológico
Authors: Cavalcanti Larissa Pinho
Published: August 2018

O racismo enquanto sistema de desigualdade social se espalhou pelo mundo, principalmente, após a Segunda Guerra Mundial, de modo que grupos brancos na prática da dominação étnica ou racial sobre outros grupos exerceriam vários tipos de controle simbólico, físico ou social (VAN DIJK, 1999, 2000, 2002). Na Ásia, o racismo é caracterizado pela supervalorização da pele mais clara ou branca, em detrimento da pele mais escura, relacionada a trabalhos expostos ao sol e, consequentemente, uma origem social mais humilde (THE GUARDIAN, 2015, THE SOUTHERN TIMES, 2016; BBC, 2016). Numa outra dimensão, a expressão e reprodução de preconceitos étnicos e ideologias em larga escala dependem, também, dos meios de comunicação de massa audiovisuais, que difundem discursos através de palavras e, principalmente, imagens. Com base em Kress e Van Leewuen (1996), Baldry e Thibault (2006), Cotrim (1996) e Leiss, Kline, Jhally (1997) analisamos duas propagandas televisivas de origem asiática que retomam o discurso do clareamento de pele ao promoverem seus produtos. Nesse sentido, analisamos os modos semióticos do audiovisual propondo uma leitura crítica dos discursos e dos sentidos gerados conjuntamente na composição das propagandas. Mostramos que o discurso do racismo nas propagandas busca envolver o ambiente doméstico e a vida pública das pessoas, e se orientam para consumidoras mulheres. Mostramos, também, que a valorização da cor da pele leva em conta padrões culturais estéticos diferentes para mulheres e homens e o que é socialmente aceito como atraente para um e outro.
