This document summarizes a study on laboratory water consumption and recyclability at Osun State University in Nigeria. The researchers evaluated the number of water taps per laboratory, conducted a pilot study that found average laboratory water use per tap was 64.26 liters, and determined water use amounts for laboratory practical sessions. Four laboratories - Industrial Chemistry, Biochemistry, Medical, and Water and Environmental - were selected for detailed influent and effluent analysis based on their water use amounts. Physical, chemical and toxic chemical analyses of the laboratory influent and effluent water found that the Biochemistry laboratory effluent required the greatest treatment for several parameters before it could be recycled. The researchers recommend further treatment and monitoring of parameters of concern
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

Effect of zeolite types ltx and lta on physicochemical parameters of drinking...eSAT Journals
Abstract In this study, the effect of zeolite types LTX and LTA, assisted by laser light transmission experiment on the physico-chemical parameters of drinking water samples have been investigated. Water samples were collected from rivers, streams, and wells from Central and Volta regions of Ghana, and zeolite masses of 0.2 and 0.5 g were added to 100 ml portions of the samples in turn. Laser light intensities transmitted through the samples before and after zeolite addition were measured and recorded. The results obtained showed raw water turbidity of 33.8 NTU and treated water turbidity of 3.0 NTU (WHO recommends the limit of 5 NTU for drinking water); transmitted light intensity for the raw and treated water samples of 0.3122 AU and 0.3345 AU, respectively. Our results also showed that water turbidity highly correlates the transmitted light intensity, and water conductivity depends on dissolved metal concentrations and temperature.

Effect of Seasonal Variation on Quality of Domestic Water Sources in Central ...theijes
The quality of water sources in the Central Gonja District in the Northern Region of Ghana has been questioned due to activities that pollute water in the area. This research analysed the quality of domestic water sources in the Central Gonja District in terms of pH, EC, Turbidity, Total hardness, Nitrate and Faecal coliform. One hundred and eight (108) water samples were collected from boreholes, rivers, rainwater and dam in the wet and dry seasons within six months. The samples were analysed in the laboratory according to the procedures and protocols outlined in the Standard Methods for the Examination of Water and Wastewater for pH, turbidity, total hardness, nitrate and faecal coliform. Analysis of the water sources showed that the parameters of boreholes measured were seasonally affected except for conductivity which was high in the dry season. All the parameters for river and dam water varied with the seasons. In relation to faecal contamination, the borehole, river water and dam were seasonally affected, and unsuitable for drinking without treatment. Based on the WHO guidelines, rainwater in the area can be regarded as potable owing to its higher quality over the other water sources in the study area. Generally, rainwater can be recommended for drinking, cooking, bathing and washing for the people of Central Gonja District.
This study highlighted the pernicious elements present in the sediment and water of Aba River.Upstream and downstream sediment and water samples were collected at four different sampling points along Aba River. The samples were analyzed for the presence of heavy metals. Microbiological analyses were carried out using the spread plate method and bacterial and fungal isolates identified using standard methods. Analyses were carried out to determine the physicochemical properties using standard methods. Results obtained showed the presence of heavy metals in sediment physicochemical parameters in the ranges of turbidity (11.00-15.00NTU), conductivity (1.80-3.09µS/cm), BOD5 (2.10-5.05mg/g), COD (19.50-25.60mg/g), TDS (610-840mg/g), pH (7.20-7.55), temperature (29.00-30.10°C), K (7.16-9.15mg/g), Na (3.53-4.85mg/g), Mg (4.30-5.40 mg/g), Cr (0.04-0.20mg/g), Zn (0.21-0.35mg/g), Fe (3.75-4.42mg/g), Al (1.05-1.25 mg/g), SO42- (11.75-13.11mg/g), PO42- (0.30-1.1 1mg/g), NO3 (6.35-8.16mg/g). Water physicochemical parameters were in the ranges of turbidity (3.30-9.00mg/l), conductivity (0.63-1.80mg/l), BOD5 (1.72-2. 50mg/l), COD (14.39-22.40mg/l), DO (2.95-5.6mg/l), TDS (245-556mg/l), pH (6.90-7.50), temperature (28.50-30.50°C), K (0.001-6.55mg/l), Na (1.25-3.55mg/l), Mg (1.50-4.60mg/l), Cr (0.00-0.15mg/l), Zn (0.01-0.13mg/l), Fe (1.15-3.95mg/l), Al (0.001-1.12mg/l), SO42- (11.75-13.30mg/l), PO42- (0.30-1.11mg/l), NO3 (6.35-8.16mg/l). The mean bacterial counts recorded for the different sampling points were higher in the wet season for sediment samples (0.97-6.00 x 106 cfu/g) than in the dry season (2.15-5.85 x 106 cfu/g), also the mean bacterial counts recorded for water samples were higher in the wet season (1.41-2.95 x 106 cfu/ml) than in the dry season (1.31-2.39 x 106 cfu/ml). The diversity of microorganisms isolated and identified were; Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Salmonella typhi, Shigella dysentariea,, Bacillus cereus, Enterobacter aerogenes, Enterococcus faecalis, Serratia mercences, Micrococcus luteus, Micrococcus roseus, Aspergillus niger, Penicillium notatum, Saccharomyces cerevisae, Fusarium poae, Rhizopus stolonifer, Rhizopus nigricans, Mucor sp. The distribution of these organisms varied between samples, distance and season. The high level of both microorganisms and heavy metals suggest that the anthropogenic activities in the River could cause health menace to users and therefore should be put to check regularly.

This document evaluates the use of ultraviolet (UV) radiation and ozone for disinfecting primary municipal wastewater effluents. Experiments tested different ozone concentrations and UV fluencies at varying pH levels. Ozone doses near 20 mg/min achieved 72-78% removal of fecal and total coliforms, and removed up to 36% of chemical oxygen demand (COD). UV achieved over 80% inactivation of bacteria. Both treatments were most effective against bacteria at pH levels other than 7. UV treatment had lower energy requirements than ozone treatment. The study demonstrates the potential for UV and ozone processes to generate safely reusable or releasable effluents from primary wastewater treatment.

The document analyzes water quality samples from three sites along the Kali River in Meerut, India. Physicochemical parameters like pH, TDS, conductivity, BOD, COD and heavy metals were found to exceed permissible limits for drinking water. pH ranged from 7.1 to 8.3, TDS from 1643-3145 mg/L, and BOD and COD indicated high organic pollution. Dissolved oxygen levels were very low. Heavy metal analysis found levels of Pb, Cr, Cd, Hg, Cu, Ni, Mn, Fe and Zn exceeded limits for irrigation and drinking water. The study indicates the river water is polluted from industrial and domestic waste and requires treatment before use.
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.

This document discusses the use of spiral reinforcement in reinforced concrete beams. It begins by explaining that beams traditionally use horizontal steel reinforcement to resist bending moments and transverse steel to resist shear forces. Using spiral reinforcement instead can increase the beam's bending moment capacity, torsional moment capacity, shear capacity, and ductility while reducing deflection. This provides better earthquake performance and accounts for load reversals. The document then discusses RCC beams and the different types, including simply supported, semi-continuous, continuous, and cantilever beams. It concludes that spiral reinforcement is more economical and provides increased strength and ductile behavior compared to traditional reinforcement configurations.

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.

This document discusses the use of spiral reinforcement in reinforced concrete beams. It begins by explaining that beams traditionally use horizontal steel reinforcement to resist bending moments and transverse steel to resist shear forces. Using spiral reinforcement instead can increase the beam's bending moment capacity, torsional moment capacity, shear capacity, and ductility while reducing deflection. This provides better earthquake performance and accounts for load reversals. The document then discusses RCC beams and the different types, including simply supported, semi-continuous, continuous, and cantilever beams. It concludes that spiral reinforcement is more economical and provides increased strength and ductile behavior compared to traditional reinforcement configurations.

PRELIMINARY STUDY ON NUTRIENT REMOVAL OF DAIRY WASTEWATER BY PILOT SCALE SUBS...paperpublications3
Abstract: This study was conducted to examine the nutrient removal efficiency of pilot scale Constructed Wetland (CW) designed to treat dairy wastewater. Two pilot scale fiber glass wetland units were constructed to function as Subsurface Horizontal Flow (SSHF) CWs. A gravel based medium was layered for inlets and outlets of each unit. Constructed Wetland bed was filled with sand and the upper layer was filled with compost: top soil mixture (1:2). Both units were planted with Schoenoplectus grossus (Giant bulrush).After establishing plants for three months, the treatment unit was saturated with seven Biochemical Oxygen Demand (BOD) loads of diluted and neutralized dairy wastewater ranging from 5g/m2d , 16g/m2d, 20g/m2d, 24g/m2d,33g/m2d, 48g/m2d and 186 g/m2d. Seven days were maintained as effective retention time under each BOD load. Control unit was maintained without the addition of dairy wastewater. Samples were collected from the inlets and outlets of each unit and analyzed for BOD, Chemical Oxygen Demand (COD),Total Nitrogen (TN) and Total Phosphorous (TP).Removal efficiencies of BOD, COD, TN and TP were calculated. The results of this study showed BOD removal efficiencies in the range of 30%-100%, COD removal efficiencies in the range of 75%-92%, TN removal efficiencies in the range of 40%-100% and for TP in the range of 0%-100% with respect to studied loading rates. Based on these results this paper suggests that this type of pilot scale SSHF CWs planted with Scheonoplectus grossus is appropriate for removal of BOD, COD, TN and TP in dairy wastewater arising from small and medium sector dairy industries.

A STUDY ON THE IMPACT OF ORGANIZATIONAL CULTURE ON THE EFFECTIVENESS OF PERFO...IAEME Publication
The main objective of this study is to analyze the impact of aspects of Organizational Culture on the Effectiveness of the Performance Management System (PMS) in the Health Care Organization at Thanjavur. Organizational Culture and PMS play a crucial role in present-day organizations in achieving their objectives. PMS needs employees’ cooperation to achieve its intended objectives. Employees' cooperation depends upon the organization’s culture. The present study uses exploratory research to examine the relationship between the Organization's culture and the Effectiveness of the Performance Management System. The study uses a Structured Questionnaire to collect the primary data. 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.

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.

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.
