A country can achieve sustainable and rapid growth in all fields by improving its connectivity and transit systems. Connectivity of people to resources by improved transit mechanism results in improved living standards. Apart from other means, the major part of connectivity of any country is through road systems. Well designed and maintained pavements provide better and long lasting service. In India, all the major road systems are designed as flexible pavements only, because of their ease of construction and less time it takes to be opened to traffic operations. The major problem with flexible pavements is their design life and high maintenance costs. Also, globally reducing petrol reserves, which are used for bitumen and asphalt production are also increasing the need for alternatives. To tackle these problems, rigid pavements can be constructed. Although the cost of construction of rigid pavements is high, its long life, high load carrying capabilities and low maintenance cost will balance the initial cost aspect. Recently, many studies are being conducted on different pozzolanic admixtures which can be used as partial replacement of cement in rigid pavements, thereby reducing its cost and enhancing properties of the mix. Here, an attempt is made to reduce the construction cost of rigid pavements by incorporating Vitrified Polish Waste (VPW) as partial cement replacement in proportions of 5% for M40 grade concrete. Further, to enhance flexural properties of pavement, Recron fibre is added to optimum VPW in increments of 0.1%, then after C.C pavement is designed for two lane two way national highway and cost benefit analysis is performed.
The project involved designing of two different types of Rigid pavements using the
AASHTOWare Pavement ME software.
1) JPCP (Jointed Plain Concrete Pavement) : It was designed as a three layered structure,
the layer distribution being as follows:
Layer 1 – PCC – 16 inch
Layer 2 – NonStabilized (Crushed gravel) – 8 inch
Layer 3 – Subgrade (A-1a) – Semi Infinite
Jointed plain concrete pavement uses contraction joints to control cracking and uses
reinforcing steel in form of dowel bars.
Transverse joint spacing is selected such that temperature and moisture stresses do not
produce intermediate cracking between joints.
This typically results in a spacing no longer than about 6.1 m (20 ft.).
2) CRCP (CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS) : It was
designed as a 4 layered structure, the layer distribution being as follows:
Layer 1 – PCC – 11.3 inch
Layer 2 – Stabilized – 4 inch
Layer 3 – NonStabilized – 8 inch
Layer 4 – Subgrade – Semi infinite
CRCP is concrete pavement reinforced with continuous steel bars throughout its length.
Its design eliminates the need for transverse joints (other than at bridges and other
structures) and keeps cracks tight, resulting in a continuous, smooth-riding surface.
Heavy duty pavements are pavements subjected to the extremely heavy wheel loads associated with freight handling vehicles in industrial facilities, such as container terminals and warehouses. Heavy duty pavement need to handle many types of freight handling vehicles, such as forklifts, straddle carriers, gantry cranes and side loaders. Heavy duty pavement often deals with slow moving or even static traffic load with ultra high load magnitude. Furthermore, the load wandering for heavy duty pavement such as contain port or warehouse is more significant than normal highway or urban road pavement. The goal of pavement design is to determine the number, material composition and thickness of the different layers within a pavement structure required to accommodate a given loading regime.

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.

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.

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.

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.

1. INTRODUCTION
After understanding the importance and necessity of rigid pavement construction many researches and
studies are conducted in this aspect. The studies mainly focused on improvement of mechanical and
durability properties of concrete by usage of various additives, admixtures and fibres to concrete mix.
These admixtures are used as partial or full replacement of cement along or without fibres. The fibres used
are also available in different types like steel, glass etc. Studies are also conducted on them individually as
well as compositely.Luiz Renato, Steiner Adriano et.al [2001] studied, the properties of sludge obtained
from polishing of ceramic tiles. X-ray diffraction, X-ray fluorescence, laser diffraction and several other
tests were conducted to study physical and chemical properties of this sludge. Also, recommended its
usage as Supplementary Cementious Material (SCM) in various engineering constructions. Jay Patel, B.K.
Shahet.al [2014] in his literature analysis about ceramic waste inclusion in concrete making concluded that,
ceramic products have good pozzolanic activity because of their manufacturing temperature and its usage
is good for economy and environment. He also concluded that, cost of construction can be reduced by 20-
30% for higher grades of concrete by its usage.
Electricwala Fatima, Ankit Jhamb, Rakesh Kumar et al [2013] have investigated on M35 grade of
concrete by replacing up to 30% of cement with ceramic dust and observed an increment in compressive
strength, flexural strength. The results showed an increase in compressive strength by 3.9% to 5.6% by
replacing 20% cement content with ceramic dust. Ponnapati Manogna, M. Sri Lakshmi [2015]
investigated on partial replacement of cement by tile waste in M30 grade of concrete in increments of 10%
up to 50%.Compressive, tensile and flexural strength tests were conducted for 7, 28 and 56 days
respectively and suggested that a replacement up to 30% can be made without compromising on design
strength. However, optimum results for compression,tension and flexure strength were attained at 10%
replacement. Abhinav. S. Pawar, K.R. Dhabekar [2014] investigated on addition of waste material (GGBS)
and steel fibresin M40 grade concrete for rigid pavement and compared with normal concrete of M40
grade.After testing it was found that, 30% GGBS is the optimum replacement for M40 grade of concrete
but, flexural strength decreased by increasing percentage of GGBS, so as to increase flexural strength, steel
fibres of two different aspect ratios (7560 & 7530) were used. Steel fibres were added in concrete by 1% of
total weight of concrete with different proportions.
Nandish S.C, Ajith B.T et.al [2015] studied about strength enhancement of conventional concrete with
addition of Coconut fibres and polypropylene fibres. The coconut fibres of various proportions like 1%,
1.5%, 2%, 2.5% and polypropylene fibres of proportions of 0.4% by volume of concrete were used in the
M40 grade concrete mix tests to determine the mechanical properties of concrete up to 7, 28, 56 and 90
days. Use of fibres tends to enhance the flexural strength of the mix. Fibre mixed concrete has higher value
than that of the control mix. For 2.0%CF and 0.4%PF of fiber, flexural strength found to be 14% higher
than that of control mix concrete. Mehul. J. Patel, S. M. Kulkarni [2013] studied effects of poly propylene
fibres on M40 grade of concrete by adding in proportions of 0.5%, 1%, and 1.5% and investigated for
compressive, flexural and split tensile strengths and reported an increase in above parameters when
compared to conventional concrete.
Vipul. D. Prajapathi, Nilay Joshi et.al [2013] experimented on usage of fine aggregate replaced by used
foundry sand in proportions of 0%, 10%, 30% and 50% for M20 grade of concrete and studied their
mechanical properties. He concluded that, maximum compressive and flexural strengths are achieved at
50% replacement of natural fine aggregate with used foundry sand and designed a pavement for
3000CVPD flow. As a part of such studies, usage of Vitrified Polish Waste (VPW) along with recron
polyester fibre is studied in this experimental investigation. Ceramic industry is extensively growing with
the infrastructural needs of the present world and waste generated is also increasing rapidly there by
incorporating these wastes in pavement construction will also help environmentally. A good study on
Indian standard codes for laboratory sampling, and testing of concrete and materials used is also done
before proceeding into testing phase, which includes the following codes (IS: 10262-2009 , IS: 456-2000 ,

IS: 2386-1963, IS: 4031-1988, IRC: 44-2008, IS: 516-1959 ), the design of rigid pavement is performed
according to standards specified by IRC: 58-2002.
1.1. Objectives of the Study
The major objectives of study are
• To enhance the mechanical properties of rigid pavements effectively by inclusion of industrial waste
admixture (VPW) as a partial cement replacement.
• Designing a rigid pavement based on VPW and Recron fibre admixed concrete mixes.
• Performing cost-benefit analysis and evaluating the reduction in cost of construction.
2. MATERIALSUSED IN INVESTIGATION
The materials like fine aggregate, coarse aggregate and cement used in this investigation are bought from
locally available sources; VPW is procured from RAK Ceramics, Samalkot, Andhra Pradesh and Recron-
3S fibres from Reliance Industries. The cement used is of OPC 43 grade and having specific gravity of
3.12 and is strictly confirming to IS: 8112-2013. The fine aggregate used is of Zone-III confining to IS:
383-1987 standards and having a specific gravity of 2.67. Two sizes of coarse aggregate confining to IS:
383-1987 standards and having sizes 20mm and 10mm is attained from local crusher units and their
flakiness and elongation index is <15% with a specific gravity of 2.69 for both sizes used. The VPW
procured is having a fineness of 98% and specific gravity of 2.46, 12mm Recron fibre is used in the study.
A chloride free plasticizer Master Rehobuild 823 PQ manufactured by B.A.S.F industries confining to IS:
9103-1999 is used to enhance workability. Mixing water confining to IS: 456-2000 is used in the
experimental investigation.
3. METHODOLOGY AND MIX DESIGN
The experimental investigation is started by conducting necessary preliminary testing and determining
required properties of materials to perform mix design. Design mix samples are casted and checked for
attaining target strength. For this design mix, cement is partially replaced by VPW in incremental
proportions of 5% and samples are casted and tested for slump, compression, flexure, split tensile and
water absorption for 7 and 28 days respectively. From the results obtained, optimum replacement of
cement by VPW is found out. To this optimum VPW replacement, Recron fibres are added in proportions
of 0.1% increments and samples are tested in the above similar manner to know the optimum fibre dosage
with optimum VPW replacement. The mix design is made for M40 grade of concrete, following
specifications of IRC: 44-2002 in accordance with IS: 10262-2008.The trail mixes casted with varying w/c
ratios to attain slump range of 50±5 mm gave a final w/c ratio of 0.38% and obtained mix proportion is
(1:1.529:2.987) i.e. 418.42Kgs cement, 640.14Kgs of fine aggregate and 1250.00Kgs of coarse aggregate
are usedcu.m of concrete along with 1.59liters of water and 2.94liters plasticizer. Aggregates of size 20mm
and 10mm are used in proportions of 60% and 40% respectively in the mix.
4. EXPEIMENTAL PROCEDURE
The experimental investigation on fresh and hardened concrete for checking its durability and engineering
properties is done strictly confining to IS: 516-1959. Compressive Strength test (C.S) is performed on
cubes of (150x150x150mm) in a compressive testing machine having capacity of 2000kN @ 5.25kN/s
loading. Flexural Strength (F.S) testing is performed on prisms of (500x100x100mm) in universal testing
machine having capacity of 2000kN @1.8kN/min. Similarly, Split Tensile Strength (S.T.S) is also
performed on cylinders of 150mm diameter and 300mm height in a compression testing machine having
capacity 2000kN @ 1.2 to 2.4N/(mm2
/min) following IS: 5186-1999. The compressive flexural and split
tensile strength tests are carried on samples for 7 and 28 days and results are calculated following above

mentioned codes. Durability tests on concrete were also conducted such as water absorption test and acid
resistance test by soaking in 5% HCl solution for 30days after initial curing of 28days.Later compressive
test is conducted on samples and results are compared with conventional concrete. The results are shown
and discussed below.
5. RESULTS AND DISCUSSION
The slump values showed a decreasing pattern with addition of VPW and further decreased more with
addition of fibres as shown in Table.1. The optimum dosage of VPW for the design mix is attained at 15%
addition. Compressive, flexural and split tensile strengths showed a considerable increase in mechanical
properties compared to other mixes at this dosage. The 28 days strength results of all mixes are shown in
Table.1 and the optimum results attained were shown in Table. 2, similarly the optimum fibre dosage is
attained at 0.3% for 15% VPW addition. The water absorption increased with increase in VPW content,
but when fibres are added the rate of absorption is considerably low. It is observed from acid resistance test
that there is a slight decrease in compressive strength of all samples, but it is well within permissible limits.
