Background:In recent time, people love online shopping but before any shopping feedbacks or reviews always required. These feedbacks help customers in decision making for buying any product or availing any service. In the country like India this trend of online shopping is increasing very rapidly because awareness and the use of internet which is increasing day by day. As result numbers of customers and their feedbacks are also increasing. It is creating a problem that how to read all reviews manually. So there should be some computerized mechanism that provides customers a summary without spending time in reading feedbacks. Besides big number of reviews another problem is that reviews are not structured.Objective:In this paper, we try to design, implement and compare two algorithms with manual approach for the crossed domain Product’s reviews.Methods:Lexicon based model is used and different types of reviews are tested and analyzed to check the performance of these algorithms.Results:Algorithm based on opinions and feature based opinions are designed, implemented, applied and compared with the manual results and it is found that algorithm # 2 is performing better than algorithm # 1 and near to manual results.Conclusion:Algorithm # 2 is found better on the different product’s reviews and still to be applied on other product’s reviews to enhance its scope. Finally, it will be helpful to automate existing manual process.

Published: June 2019

Background:Quinoline is a type of N-based organic heterocyclic biologically active compound. Quinolines have grasped the interest of scientists because of their wide scope of applications. Several methods have been developed for the synthesis of quinoline and its derivatives. In this study, a new, efficient, simple, one-pot synthesis of the substituted quinolines was developed by using palladium nanoparticles as a catalyst.Methods:Catalyst synthesized by algal extract of green alga Botryococcus braunii and palladium acetate solution, and characterized by different instrumental techniques like FTIR, SEM, and XRD. The synthesized palladium nanoparticles explored for the catalytic activity in the synthesis of quinoline derivatives by the use of 2-aminobenzyl alcohol in toluene with acetyl derivatives followed by the addition of potassium hydroxide. The formation of the product was confirmed by 1HNMR, 13C NMR, and electron ionization mass spectra.Results:The formation of palladium nanoparticles characterized by visual observation means the color change from light pale yellow to dark brown indicates the reduction of palladium ions into palladium nanoparticles. Synthesized palladium nanoparticles characterized by FTIR spectrum of the algal extract of green algae B. braunii for the presence of proteins, lipids, carbohydrates, carotenoids, vitamins and other secondary metabolites in algal extract, which function as active components for bioreduction. The morphology of the catalyst was confirmed by SEM and X-ray diffraction measurements for shape, crystalline nature and size. The synthesized palladium nanoparticles explored for the catalytic activity in the synthesis of quinoline derivatives by use of 2-aminobenzyl alcohol in toluene and added acetyl derivatives followed by the addition of potassium hydroxide. In order to establish the optimum heating method, a comparative study between conventional and microwave heating method was carried out in the presence of palladium nanoparticles as a catalyst.Conclusion:This protocol provides a convenient and practical procedure for the preparation of quinoline derivatives from 2-aminobenzyl alcohol, acetyl derivatives, potassium hydroxide and palladium nanoparticles as a catalyst. This protocol will be helpful in synthesizing other quinoline derivatives and several organic heterocycles which are used in different fields such as biological, industrial, pharmaceutical, chemical, medical, etc.

Gestión del agua subterránea en los acuíferos de la cuenca del río Ayuquila-Armería en Jalisco y Colima, México
Authors: Hernández Juárez Rodrigo Alejandro , Martínez Rivera Luis Manuel , Peñuela-Arévalo Liliana Andrea , Rivera-Reyes Samuel 
Published: June 2019

El objetivo de este artículo es analizar el papel de las concesiones de agua subterránea inscritas en el Registro Público de Derechos de Agua, como instrumento de planeación para el agua subterránea en la cuenca del río Ayuquila-Armería. Se utilizó una base de datos de dicho instrumento, con los registros de 1994 a 2015, para examinar el uso y el volumen de agua consumido en ese lapso en las concesiones otorgadas. A partir de 2009 hubo un incremento en estas variables y una disminución acelerada de la disponibilidad de agua en los acuíferos, por lo que algunos se consideraron “sobreexplotados”. Se concluye que la delimitación administrativa de los acuíferos no contribuye a entender la dinámica geohidrológica, y que dicho instrumento no está funcionando para la planeación y el control, por lo que es necesario revisar la gestión actual del agua subterránea, y promover un cambio hacia una visión integral de ella, de acuerdo con la teoría de los sistemas de flujo.

<p>En las elecciones del año 2015, el Partido de la Revolución Democrática (prd) perdió el predominio que ostentaba en la Ciudad de México. Este fenómeno se explica a partir del concepto de polivalencia electoral, el cual hace referencia a los factores de mayor importancia que determinan los resultados electorales. En este artículo sostenemos que la ineficaz acción de gobierno, las pugnas internas por el reparto de candidaturas, la aparición del morena y los errores cometidos durante las campañas políticas, provocaron que el prd perdiera el poder</p>

Published: June 2019

la caracterización de la vegetación a largo plazo en los bosques húmedos premontanos transición seca de Costa Rica ha sido muy escasa. Objetivo: realizar un estudio comparando dos sitios, uno más conservado y el otro muy degradado. Métodos: analicé la estructura y la composición de la vegetación leñosa de dos remanentes de bosque húmedo premontano transición seca, en Los Llanos de La Garita (sitio más alterado) y Bosque Andrómeda (sitio más conservado) en Atenas, Costa Rica, durante aproximadamente 10 meses comprendidos entre 2015-2016. En cada sitio establecí 20 parcelas circulares (500m2) para el muestreo de los árboles con DAP>10cm. Resultados: identifiqué para Andrómeda, 29 familias, 51 especies y 305 individuos. Por su parte, en Los Llanos, encontré 16 familias, 18 especies y 76 individuos. Las especies más abundantes en Andrómeda fueron Guazuma ulmiforia, Anacardium excelsum y Calycophyllum candidissimum; mientras que en Los Llanos fueron Enterolobium cyclocarpum, Bursera simaruba y Andira inermis; las especies de mayor frecuencia en Andrómeda fueron Guazuma ulmiforia, Anacardium excelsum y Cedrela odorata y en Los Llanos Enterolobium cyclocarpum, Bursera simaruba y Tabebuia rosea; en cuanto a la dominancia Cedrela odorata, Pseudobombax septenatum y Enterolobium cyclocarpum fueron las especies presentes en el sitio más conservado y Enterolobium cyclocarpum y Ficus Guazuma ulmifolia fueron las especies en el sitio más alterado. En cuanto a los índices de biodiversidad encontré que Andrómeda muestra una diversidad de H=3,22 y Los Llanos fue de H=2,50. Andrómeda mostró mayor dominancia DS=0,95 que Los Llanos con DS=0,89. Ambos sitios mostraron una alta equitatividad de especies J=0.86, también presentaron casi los mismos valores de similitud de especies Bray-Curtis=0,81 y Jaccard=0,89. Estimé que la riqueza de especies según los estimadores no paramétricos (ACE, Chao 1, Chao 2, Jackknife 1, Bootstrap) para Andrómeda está entre 59-111 especies, mientras que para el otro sitio fue de 20 a 28 especies. Conclusión: este estudio mostró una composición florística similar entre ambos sitios, lo que facilitará los procesos de restauración ecológica; sin embargo, la estructura horizontal es diferente.

Intrachromosomal regulation decay in breast cancer
Authors: Anda-Jáuregui Guillermo de , Fresno Cristobal , García-Cortés Diana , Enríquez Jesús Espinal , Hernández-Lemus Enrique 
Published: June 2019

Abstract
Biological systems exhibit unique phenotypes as the result of the expression of a genomic program. The regulation of this program is a complex phenomenon, wherein different regulatory mechanisms are involved. The deregulation of this program is at the centre of the emergence of diseases such as breast cancer. In particular, it has been observed that coregulation patterns between physically distant genes are lost in breast cancer.
In this work, we present a systematic study of chromosome-wide gene coregulation patterns in breast cancer as inferred by information theoretical measures over large (whole-genome expression in several hundred transcriptomes) experimental data corpora. We analyzed the chromosomal distance decay of correlations and found it to be with fat-tail distribution in breast cancer while being fundamentally constant in nontumour samples.
After model discrimination analyses, we concluded that the behaviour of the breast cancer distributions belongs to an intermediate regime between power law and Weibull distributions, with distinctive contributions corresponding to different chromosomes. This behaviour may have biological implications in terms of the organization of the gene regulatory program, and the changes found in this program between health and disease.
