Cement is the world's most used construction binder material. Cement production emits large amounts of CO2 and consumes significant amount of energy. As a result, it is necessary to find a new concrete material to replace traditional Portland cement concrete, which is environmentally stressful, yet provides an effective building material. Geopolymer is an emerging alternative binder to Portland cement for making concrete. Geopolymer concrete is principally produced by utilizing industrial by-product materials such as fly ash, blast furnace slag, and other aluminosilicate materials. RCC structures undergo serious durability problems like spalling, erosion, wear, cracking, corrosion etc. years after the construction. Repair to damaged concrete are important not only to ensure the planned useful life, but also to provide good performance and security.

issue, Self Compacting Geopolymer Concrete has been introduced. The SCGC doesn't require
any additional compaction it will flow and compacted by its own weight. This concrete is made
up of industrial by-products like Fly ash, GGBFS and Silica Fume and activated with alkaline
solution. The earlier research was mostly on Fly ash based SCGC. In few research works Fly
ash was partially replaced with GGBS and Silica Fume. They evaluated the compressive
strength of concrete with varying molarties of NaOH; curing time and curing temperature. The
flexural behavior of the concrete also examined. The Fly ash based SCGC was got high
compressive strength in heat curing as well as low compressive strength in ambient curing.
The presence of GGBS improves the strength in ambient curing. For aiming the high strength
in ambient curing Fly ash will be completely replace and examine with different mineral
admixtures.
The presentation summarizes the use of geopolymers in water treatment. Geopolymers are amorphous microporous aluminosilicate materials that can be prepared from various industrial side-products in mild synthesis conditions.
Geopolymer concrete is an innovative, eco-friendly construction material.

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.
A STUDY ON TALENT MANAGEMENT AND ITS IMPACT ON EMPLOYEE RETENTION IN SELECTED...IAEME Publication
The goal of this study was to see how talent management affected employee retention in the selected IT organizations in Chennai. The fundamental issue was the difficulty to attract, hire, and retain talented personnel who perform well and the gap between supply and demand of talent acquisition and retaining them within the firms. The study's main goals were to determine the impact of talent management on employee retention in IT companies in Chennai, investigate talent management strategies that IT companies could use to improve talent acquisition, performance management, career planning and formulate retention strategies that the IT firms could use. The respondents were given a structured close-ended questionnaire with the 5 Point Likert Scale as part of the study's quantitative research design. The target population consisted of 289 IT professionals. The questionnaires were distributed and collected by the researcher directly. The Statistical Package for Social Sciences (SPSS) was used to collect and analyse the questionnaire responses. Hypotheses that were formulated for the various areas of the study were tested using a variety of statistical tests. The key findings of the study suggested that talent management had an impact on employee retention. The studies also found that there is a clear link between the implementation of talent management and retention measures. Management should provide enough training and development for employees, clarify job responsibilities, provide adequate remuneration packages, and recognise employees for exceptional performance.
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.
INFLUENCE OF TALENT MANAGEMENT PRACTICES ON ORGANIZATIONAL PERFORMANCE A STUD...IAEME Publication
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.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

1. INTRODUCTION
The alkaline liquid reacts with the silicon (Si) and the aluminum (Al) in by-product
materials such as fly ash to produce binders. The chemical reaction that takes place in
this case is a polymerization. Geopolymer concrete is concrete which does not require
any Portland cement in its making. The two main constituents of geo polymers are the
source materials and the alkaline liquids. The materials used for geo polymers lies on
alumina-silicate rich in silicon (Si) and aluminium (Al). Alternatively, by-product
materials such as fly ash, silica fume, slag, red mud, etc could be used as source
materials. Liquids are from soluble alkali metals that are usually sodium or potassium
based. The alkaline liquid used in polymerisation is a mixture of sodium hydroxide
(NaOH) or potassium hydroxide (KOH) and sodium silicate.
2. MATERIALS USED
2.1. Fly Ash
The Fly ash is residue resulting from the burning of ground or powdered coal, which
is taken from the boiler by flue gases. Fly ash can be used in Portland cement
concrete to increase the performance of the concrete. Fly ash is one of the remains
generated in burning, and contains the fine particles that flow with the flue gases.

2.2. Coarse Aggregate
Coarse aggregate are an inert materials used in construction. Hard stones are crushed
in required sizes. The material that is retained on IS sieve of size 4.75 is called coarse
aggregate. These aggregates combine with cement and fine aggregates with water to
form concrete. Coarse aggregates of sizes 10mm and 20mm are used in this study.
The properties of coarse aggregate as shown in Table 1d

2.4 Sodium Hydroxide Solution
The alkaline activator used in geo polymerisation is a mixture of sodium hydroxide
and sodium silicate. The alkali percentage is a significant factor in controlling the
leakage of alumina and silica from fly ash particles, following geo polymerization and
mechanical properties of hardened geopolymer. The gel composition calculated in the
sample animate with the mixture of sodium silicate and NaOH is increased in Na and
Al [1].
This solution is having of solute and solvent. Solute is the immerged substance
and solvent is the substance in which the solute is dessolved.A solute can be liquid or
solid. In NaoH solution sodium hydroxide is the solute that is in solid state and water
is the solvent that is liquid form. Notice that solute being a solid and is calculated in
terms of weight in (grams) .And the solvent water is denoted interms of volume.

Open porosity can be drawn and is readily filled with gel as soon as the liquid phase
is able to mix with the ash particles. The liquid phase is vital as a fluid transport
medium allowing the activator to reach and act with the fly ash particles.
3. METHODOLOGY
3.1. Preparation of Alkaline Solution
In this experiment the compressive strength of geo- polymer concrete is examined for
the mixes of varying molarities of Sodium hydroxide (8M, 12M, and 16M). The
molecular weight of sodium hydroxide is 40. To prepare 8M i.e. 3 molar sodium
hydroxide solutions, 120g of sodium hydroxide flakes are weighed and they can be
dissolved in dissolved in distilled water to form 1 litre solution. For this, volumetric
flask of 1 litre capacity is taken, sodium hydroxide flakes are added slowly to distilled
water to prepare 1liter solution. The weights to be added to get required molarity are
given in Table 2.

3.2. Proportioning of Geo-Polymer Concrete
The fly ash, fine aggregates and coarse aggregates are mixed in a container and then
the alkaline solution was added to prepare the geopolymer concrete. The geopolymer
concrete is poured in 100 mm cube moulds. The Geopolymer concrete is in dark
colour with shiny appearance. The proportions of mixing are as given in Table 3. As
per no code provisions for the mix design of geo- polymer concrete, the density of
geo-polymer concrete is assumed as 2440 kg/m3
. The other values are found by
assuming the density of concrete.
The aggregate takes place the volume is assumed to be 65%. The quantities of all
ingredients are kept constant as given below Table 3 except the molarity of NaOH is
changed in the each mix. The other method used in the making of normal concrete is
included to prepare geopolymer concrete. First, the fine aggregate, coarse aggregate
and fly ash are mixed in dry condition for 3-4 minutes and after that the alkaline
solution which is an addition of Sodium hydroxide solution and Sodium silicate
solution with super plasticizer is mixed to the dry mix.
The mixing is prepared about 6to8 minutes for correct bonding of the materials.
After the mixing is done, the cubes are casted by providing with good compaction.
The size of the cube which is taken is of size 100*100*100 meters. the curing of geo-
polymer concrete cubes, the two methods are applied, one method is by kept the cubes
in hot air oven and by keeping the cubes in direct sun-light. In the oven curing, the
cubes are removed and kept in oven at 60o
c for an hour. Then the cubes are removed
and kept in oven at 50o
c for 7days. In the sun light curing, the cubes are removed after
1 day of casting and they are kept in the direct sunlight for 7 days. The mix

4. CONCLUSIONS
We calculated that the compressive strength is increased with the Increase in the
Molarity of sodium hydroxide.
For 7 days of curing the increased value in the compressive strength is significant.
Compare to hot air oven curing and curing by direct sun light, oven cured specimens
gets more the compressive strength but sunlight curing is conveniently good for
practical conditions.
