Hydrochemistry and Quality Assessment of Groundwater in Naini Industrial Area, Allahabad District, Uttar Pradesh

Abstract: The chemical characteristics of groundwater in and around the industrial area of Naini district, Allahabad have been studied to evaluate the suitability of water for irrigation and domestic uses. Sixty five water samples representing the shallow and deep groundwater of the area were collected and analysed for pH, EC, TDS, HCO 3 , CO 3 , SO 4 , Cl, Ca, Mg, Na and K. It is observed that the quality of the groundwater is suitable for domestic use with some exception. The observed high quantity of heavy metals at some sites requires immediate attention and detailed study. The calculated values of SAR, RSC and sodium percentage indicate the good to permissible quality of water. However, the high sodium percentage and RSC values at certain sites restrict its suitability for agricultural purposes.

A Comparative Study of Air Quality Index Based on Factor Analysis and US-EPA Methods for an Urban Environment

Abstract: There are many different air quality indexes, which represent the global urban air pollution situation. Although the index proposed by USEPA gives an overall assessment of air quality, it does not include the combined effects (or synergistic effects) of the major air pollutants (Shenfeld, 1970; Ott and Thom, 1976; Thom and Ott, 1976; Murena, 2004). So an attempt is made to calculate the Air Quality Index based on Factor Analysis (NAQI) which incorporates the deficiencies of USEPA method. The daily, monthly and seasonal air quality indexes were calculated by using both these methods. It is observed that a significant difference exists between NAQI and EPAQI. However, NAQI followed the trends of EPAQI when plotted against time. Further, the indexes were used to rank various seasons in terms of air pollution. The higher index value indicates more pollution in relative terms. Moreover, the index may be used for comparing the daily and seasonal pollution levels in different sites.

Language Identification and Morphosyntactic Tagging: The Second VarDial Evaluation Campaign

Abstract: We present the results and the findings of the Second VarDial Evaluation Campaign on Natural Language Processing (NLP) for Similar Languages, Varieties and Dialects. The campaign was organized as part of the fifth edition of the VarDial workshop, collocated with COLING’2018. This year, the campaign included five shared tasks, including two task re-runs – Arabic Dialect Identification (ADI) and German Dialect Identification (GDI) –, and three new tasks – Morphosyntactic Tagging of Tweets (MTT), Discriminating between Dutch and Flemish in Subtitles (DFS), and Indo-Aryan Language Identification (ILI). A total of 24 teams submitted runs across the five shared tasks, and contributed 22 system description papers, which were included in the VarDial workshop proceedings and are referred to in this report.
