Water is an important natural resource, which forms the cause of all life. Water is
one of the most requisite materials in our day to day life. It is a key resource in all
economic activities ranging from agriculture to industries. Only a minimal fraction of
the planet’s plentiful water is available to the living beings as fresh water. About 97%
is found in the oceans and is very salty for drinking, irrigation, or industry. The
remaining 3% is fresh water. About 2.997% of it is arrested in ice caps or glaciers or
is concealed so deep that it costs too much time & money to extract. Only about
0.0035 of Earth’s total volume of water is easily available to us as soil moisture,
exploitable ground water, water vapor, rivers, lakes and streams. In this present study
by a systematic sampling has been carried out to find the water quality parameters of
the Lake, by collecting samples from Six different positions, which covering entire
area of the lake, and the stations were distributed covering the periphery of the entire
tank, and also considering the inflow and the discharges and to suggest required
management techniques to make water free from the pollution
The quality of any body of surface or ground water
is a function of either both natural influences and human
influences. Without human influences water quality would be
determined by the weathering of bedrock minerals, by the
atmospheric processes of evaporation, transpiration and the
deposition of dust and salt by wind, by the natural leaching of
organic matter and nutrients from soil, by hydrological factors
that lead to runoff, and by biological processes within the aquatic
environment that can alter the physical and chemical
composition of water. Declining water quality has become a
global issue of concern as human populations griesrow, industrial
and agricultural activities expand, and climate change threatens
to cause major alterations to the hydrological cycle.

ABSTRACT- Three decades data (1984 – 2015) was used to study the effect of surface water temperature, pH, dissolved
oxygen, nitrate, phosphate and silicate on chlorophyll a concentration in three water bodies meant for fish culture (locally
known as Bheries) in East Kolkata Wetlands. The data revealed significant spatio-temporal variations (p < 0.01). The
increasing trend of temperature, nitrate and phosphate reflects the effect of intense urbanization at local level. The
pronounced variation of dissolved oxygen and chlorophyll a (decreasing trend) may be attributed to increased load of
sewage in the selected water bodies, which has posed an adverse impact on the phytoplankton standing stock as revealed
through decreasing chlorophyll a trend.

INFLUENCE OF LEACHATE MIGRATION ON GROUND WATER QUALITY Dr. Naveen BP
In this paper, the concept of leachate pollution index, a tool for quantifying the leachate pollution potential and water quality index for surrounding water bodies of Mavallipura landfill site in Bangalore has been applied. It has been found that the leachate generated from the Mavallipura landfill site has high contamination potential to the surrounding water bodies. The results revealed that quality of ground water resources in Mavallipura landfill is deteriorating largely, as a result of the poor practice of solid waste management. Hence, an effective remedial plan needs to be prepared for the sustainable water quality maintenance of the area.
Abstract— 11 wells in Wadi Fatimah were chosen to perform this study. The studied area was classified into three regions namely Abo-Hassani, Al-Khief, and Allaf. In Abo-Hassani, the water quality agrees with the WHO standards. The TDS was between 175 and 339 ppm. The hardness was below 193 ppm. The sodium and the chloride were below 71 and 63 ppm, respectively. The water here suffers from the presence of E.Coli. In Al-Kheif region, the water suffers from the high TDS 1077 ppm and the presence of E. Coli. In Allaf region the TDS was high a little (487 ppm), but still within WHO standards for drinking water. In this region, the sulfate value and the total hardness were above 250 ppm, which exceeds the WHO standards.

CHARACTERIZATION OF LEACHATE FROM MUNCIPAL LANDFILL AND ITS EFFECT ON SURROUN...Dr. Naveen BP
Percolating water passing through waste becomes contaminated and will have dissolved soluble organic and inorganic compounds as well as suspended particles. Also the pore fluid of the waste is often released and mixes with this water. The entire contaminated fluid is called leachate. There are many factors that affect leachate production like annual precipitation, runoff, infiltration, evaporation, transpiration, and freezing, mean ambient temperature, waste composition, waste density, initial moisture content, and depth of the waste fill. The production of leachate reduces when a landfill is closed. The decomposition of waste in presence of water can be separated into two different phases of degradation viz., initial aerobic and subsequent anaerobic. Generally, the leachate undergoes natural chemical changes over time that reduces its toxicity. Some of the soluble contaminants enrich the water table, or the saturated zone. Some of remaining molecules naturally adsorbed to the clay liner particles. The paper discusses the characteristics of leachate generated from municipal solid waste landfill and its effect on surrounding water bodies near Mavallipura landfill area in Bangalore. Two samples of water from the nearby pond and well were collected from downstream of Mavallipura landfill site. Physico-chemical characterization of leachate has shown that the leachate contains high concentrations of organic and inorganic constituents beyond the permissible limits. While the heavy metals concentration was in traces as the waste is dumped in the landfill is mainly domestic in nature. The pH of the leachate is marginally alkaline as the pH is 7.4. The results also showed that the highest metal concentration that exists in the leachate was Iron which is about of 11.16 ppm. BOD5 and COD of the leachate are 1500 mg/l and 10400 mg/l, respectively. The leachate characteristics indicate favorable growth of algae in natural water contaminated with leachate with the alkaline condition and with the presence of magnesium as nutrient, which has been confirmed in the nearby surface pond. Knowledge of leachate quality will be useful in planning and providing remedial measures to protect surface and ground water quality in the area.
Factor analysis as a tool for evaluation of spatial and temporal variations i...IOSR Journals
In this case study, factor analysis was applied for evaluation of temporal/spatial variations in the
groundwater quality of Aravakurichi block, Karur district, Tamil Nadu, India. This statistical technique was
employed for the better interpretation of large complex water quality data set obtained from twenty five
groundwater locations in four seasons during the year 2012. The water samples were characterized for the
physico-chemical parameters such as pH, total alkalinity, electrical conductivity, total hardness, calcium ions,
magnesium ions, total dissolved solids, fluorides, chlorides and sulphates. Factor analysis indicated four factors
initially and when rotation of the factor axis was executed, it yielded two factors with clear indication of high
loadings for some variable and low loadings for others, facilitating data interpretation in terms of original
variables. Overall, this case study demonstrated the effectiveness of factor analysis to identify marker variables
for assessing the chemistry of groundwater besides earmarking representative sampling stations to undertake
suitable water quality management in a shortest possible time.
SEDIMENT QUALITY ASSESSMENT OF AVARAGERE LAKE, DAVANAGERE CITY - A CASE STUDYAM Publications
Avaragere Lake in Davangere was studied for chemical and physical parameters at five locations, for a period of six months (April 2014 to Sep 2014). Lake has been subjected to human interferences regularly and water quality was to be getting deteriorated profoundly. Major anthropogenic activities practiced in and around the stretch: agriculture, discharging of sewage waste etc was generating serious threat to the biota of the lake by altering the physical, chemical and biological concentration of the lake system. The other possibility is that since there are no major industries in the project area, the major source of organic pollutants is only the domestic source.
Monthly data’s been collected. Different parameters studied were pH, Conductivity, organic carbon, nitrogen, phosphorus, potassium, zinc, copper, iron, organothiophosphate and pyrethroid content. The results obtained from the above study indicate that the water of Avaragere Lake organothiophosphate and pyrethroid content shows very low concentrations even at nanogram. Manganese and iron concentrations of sediment sample in avaragere lake shows high level of pollution and ecological balance of Lake is totally disturbed.

BROAD UNEXPOSED SKILLS OF TRANSGENDER ENTREPRENEURSIAEME Publication
Since ages gender difference is always a debatable theme whether caused by nature, evolution or environment. The birth of a transgender is dreadful not only for the child but also for their parents. The pain of living in the wrong physique and treated as second class victimized citizen is outrageous and fully harboured with vicious baseless negative scruples. For so long, social exclusion had perpetuated inequality and deprivation experiencing ingrained malign stigma and besieged victims of crime or violence across their life spans. They are pushed into the murky way of life with a source of eternal disgust, bereft sexual potency and perennial fear. Although they are highly visible but very little is known about them. The common public needs to comprehend the ravaged arrogance on these insensitive souls and assist in integrating them into the mainstream by offering equal opportunity, treat with humanity and respect their dignity. Entrepreneurship in the current age is endorsing the gender fairness movement. Unstable careers and economic inadequacy had inclined one of the gender variant people called Transgender to become entrepreneurs. These tiny budding entrepreneurs resulted in economic transition by means of employment, free from the clutches of stereotype jobs, raised standard of living and handful of financial empowerment. Besides all these inhibitions, they were able to witness a platform for skill set development that ignited them to enter into entrepreneurial domain. This paper epitomizes skill sets involved in trans-entrepreneurs of Thoothukudi Municipal Corporation of Tamil Nadu State and is a groundbreaking determination to sightsee various skills incorporated and the impact on entrepreneurship.

IMPACT OF EMOTIONAL INTELLIGENCE ON HUMAN RESOURCE MANAGEMENT PRACTICES AMONG...IAEME Publication
There is increasing acceptability of emotional intelligence as a major factor in personality assessment and effective human resource management. Emotional intelligence as the ability to build capacity, empathize, co-operate, motivate and develop others cannot be divorced from both effective performance and human resource management systems. The human person is crucial in defining organizational leadership and fortunes in terms of challenges and opportunities and walking across both multinational and bilateral relationships. The growing complexity of the business world requires a great deal of self-confidence, integrity, communication, conflict and diversity management to keep the global enterprise within the paths of productivity and sustainability. Using the exploratory research design and 255 participants the result of this original study indicates strong positive correlation between emotional intelligence and effective human resource management. The paper offers suggestions on further studies between emotional intelligence and human capital development and recommends for conflict management as an integral part of effective human resource management.

For this study, Thirty-six non-clinical employees were selected from twelve randomly selected Health Care organizations at Thanjavur. Thirty-two fully completed questionnaires were received.
Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

ATTRITION IN THE IT INDUSTRY DURING COVID-19 PANDEMIC: LINKING EMOTIONAL INTE...IAEME Publication
Globally, Millions of dollars were spent by the organizations for employing skilled Information Technology (IT) professionals. It is costly to replace unskilled employees with IT professionals possessing technical skills and competencies that aid in interconnecting the business processes. The organization’s employment tactics were forced to alter by globalization along with technological innovations as they consistently diminish to remain lean, outsource to concentrate on core competencies along with restructuring/reallocate personnel to gather efficiency. As other jobs, organizations or professions have become reasonably more appropriate in a shifting employment landscape, the above alterations trigger both involuntary as well as voluntary turnover. The employee view on jobs is also afflicted by the COVID-19 pandemic along with the employee-driven labour market. So, having effective strategies is necessary to tackle the withdrawal rate of employees. By associating Emotional Intelligence (EI) along with Talent Management (TM) in the IT industry, the rise in attrition rate was analyzed in this study. Only 303 respondents were collected out of 350 participants to whom questionnaires were distributed. From the employees of IT organizations located in Bangalore (India), the data were congregated. A simple random sampling methodology was employed to congregate data as of the respondents. Generating the hypothesis along with testing is eventuated. The effect of EI and TM along with regression analysis between TM and EI was analyzed. The outcomes indicated that employee and Organizational Performance (OP) were elevated by effective EI along with TM.

By implementing talent management strategy, organizations would have the option to retain their skilled professionals while additionally working on their overall performance. It is the course of appropriately utilizing the ideal individuals, setting them up for future top positions, exploring and dealing with their performance, and holding them back from leaving the organization. It is employee performance that determines the success of every organization. The firm quickly obtains an upper hand over its rivals in the event that its employees having particular skills that cannot be duplicated by the competitors. Thus, firms are centred on creating successful talent management practices and processes to deal with the unique human resources. Firms are additionally endeavouring to keep their top/key staff since on the off chance that they leave; the whole store of information leaves the firm's hands. The study's objective was to determine the impact of talent management on organizational performance among the selected IT organizations in Chennai. The study recommends that talent management limitedly affects performance. On the off chance that this talent is appropriately management and implemented properly, organizations might benefit as much as possible from their maintained assets to support development and productivity, both monetarily and non-monetarily.
A STUDY OF VARIOUS TYPES OF LOANS OF SELECTED PUBLIC AND PRIVATE SECTOR BANKS...IAEME Publication
Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%. It shows the dark area of Indian banking sector.

ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

1. INTRODUCTION
Lakes, ponds and streams constitute fresh water habitats, which harbor aquatic life. They are
subjected to various natural processes taking place in the environment like the hydrologic
cycle. They are also the natural sources for all kinds of chemical reactions. In the presence of
sunlight, wind, convection currents of water and the potential energy of the stream will mix
and stir the water of the water bodies. With unprecedented developmental activities, human
beings are responsible for choking several lakes to death. Storm water runoff, discharge of
sewage and industrial effluents into the lakes are few of the common causes where various
toxic compounds enter the aquatic ecosystems resulting in the deterioration of lake water
quality. This loss of water quality is causing health hazards, death of aquatic lives and crop
failures. Under such conditions, the need to study and monitor the condition of lakes has
become very critical. The ever-increasing importance and threat to long term sustainability of
the lakes due to industrialization makes the present study highly relevant
