 Abstract

Clean air is the foremost requirement to sustain healthy lives of mankind and those of the supporting ecosystem which is turn effect wellbeing. Release of particulate matter and various gaseous emissions has been on rise due to rampant industrialized growth. The ambient air quality is being deteriorated day by day due to various natural as well as anthropogenic sources. The pollutant data (RSPM, PM 2.5, NO2 and SO2 ) from State Pollution Control Board for period June 2017 to May 2018 has been used for this study . The study reveal that sampling site with heavy traffic density/load recorded the higher concentrations of RSPM, PM 2.5, NO2 and SO2 in all the seasons. Higher concentration of RSPM (178.0 �g/m3 ) and PM 2.5 (51.2 �g/m3) were observed in summer season at all the sites whereas striking feature of higher concentrations observed in case of gaseous pollutant NO2 (24.6 �g/m3) and SO2 (5.1 �g/m3) in winter season at all the sites. Lowest concentrations of all the pollutants observed in Monsoon season at all the sites. Factor analysis was carried out using Principal Component Analysis for all the four pollutants. The major sources identified in the study which were responsible for the higher concentration of pollutants are Vehicular emission (from petrol and diesel driven vehicles) and crustal re-suspension. Some contributions are from wood and leaf burning and coal combustion.

 Abstract

Learning a second language helps to communicate across cultures. In India, English is the second language for many who speak more than one language. As far as India is considered, English is the second language and the second language learners are referred as L2 learners. The L2 learners of today are different. They have grown up with information technology. New technological devices have entered into the teaching and learning avenues and have brought in a lot of changes. Digital technology has changed the way of communication. The learner society is imbibed with digital devices and technological advances. They tend to be digitally literate. So, the teachers have to follow the digital path to teach English language and to enhance the grammatical learning of the L2 learners. The teachers, in other words, facilitators have tuned themselves up to the expectations of the learners

 Abstract

Development in various industries is essential to mankind, but also it seems to possess a serious threat to the environment and humanity. The effluents are discharged into the land and water bodies, which is responsible for the destruction of aquatic creatures. Heavy metals are the major factors responsible for water contamination. Traditional treatment methods like microfiltration, ultrafiltration, Nanofiltration, reverse osmosis, etc., are a monotonous and painstaking processes, and it also adds on to the capital cost. Bio sorption is such a method that employs living organisms or parts of them to remove metals. Bacteria, fungi, and algae are proven to be efficient biosorbents. Extracellular Polymer Substances(EPS) are bacterial secretions that have shown to be potential biosorbents. This paper acknowledge on the metal complex formation capability of EPS extracted from wastewater. The advantage of an EPS in the biotreatment of heavy metals is studied with the optimization of the process parameter. The viability of adsorption and desorption behavior of EPS /sodium alginate(SA) bead prepared in a 2:8 ratio for Ni removal has been investigated through batch studies. The optimal condition for adsorption is found to be pH:6.5; adsorbent dose:6g; initial metal concentration: 75 mg/L and temperature:40�C

People get easily tired of eating the same things again and again. They then resort to restaurant/ junk food which affects their health as the vegetables and oil used by them are of suboptimal quality. The proposed system suggests recipes according to the fruits and vegetables available to the user. User scans the available fruits and vegetables and android application displays a list of possible recipes. The application is personalized, which means the recipes displayed are filtered according to the user�s preferences and health conditions. For example, the proposed application does not display a spicy recipe to a user for elderly people. This makes our application more health friendly. It quickly displays a list of possible recipes. Another interesting aspect of the proposed project is using Machine Learning approach. Detection is one of the challenging and interesting problems in machine learning. This is done using Tensorflow ,which is free open source library.

 Abstract

In the recent years, various efforts have been taken by individuals and the government to introduce a cashless system of making payments in the economy of India. Under this initiative, the government of India launched the �Digital India� campaign and encouraged the citizen of India to indulge in electronic methods of making payments. This was done in a two-fold manner; by introducing simpler platforms for on-the-go payments such as e-wallets and Unified Interface Payments, and by providing incentives to those indulging in electronic methods of payments in the form of discounts and cashbacks. As a result of these efforts taken by both private and public players in the market, the usage of cash has substantially reduced in the country. It has been commonly observed by various scholars and researchers that most developed economies transact on the electronic platform. This is majorly due to its network, speed and reliability. This paper aims to identify the relationship between digital payments and its impact on the economy of India. For the purpose of analysis debit and credit card transactions along with the more recently introduced UPI transactions have been considered. GDP at constant prices has been taken as the dependent variable. Data has been collected for the years 2011 to 2019. Analysis revealed that out of debit and credit card transactions, debit card transactions have a greater impact on the GDP of the country. UPI has not yet been developed and used enough to make a significant impact on the economic growth of the country.

 Abstract

Licensed establishments have the legal and moral responsibility of serving alcohol responsibly. Responsible Service of Alcohol (RSA) or Responsible Beverage Service (RBS) ensures that alcohol abuse and alcohol related harms are under control. While there has been extensive research done on the impact of RBS in controlling alcohol related harms, research on customer�s perception and attitude towards RBS is limited. Like any enforced social cause, there exists resistance towards accepting RBS by customers, especially when a server or bartender denies a customer further service of alcoholic beverages. This study attempts to examine the acceptance of responsible beverage service practices by customers and its influence on controlling alcohol abuse and intoxication. Survey questionnaire was administered to customers who frequent bars in star hotels. The responses were analyzed using SPSS 21 (Statistical Package for the Social Science). The results would shed light on what the customers thought was the best practices in RBS and would give the hospitality professionals insight to the most practical and effective ways of practicing RBS.
