Effects of Metakaolin Content on Fresh and Hardened Properties of Self Compac...ijceronline
Self-compacting concrete (SCC) is an innovative concrete that does not requires vibration for placing and compaction. SCC has higher powder content and a lower coarse aggregate volume ratio as compared to normally vibrated concrete. If only cement is used in SCC, it becomes high costly, susceptible to be attack and produces much thermal crack. Therefore it is necessary to replace some of the cement by additives like Metakaolin to achieve an economical and durable concrete. Metakaolin (MK) is a pozzolanic material. It is a dehydroxylated form of the clay mineral kaolinite. It is obtained by calcination of kaolinitic clay at a temperature between 500°C and 800°C. Kaolin is a fine, white, clay mineral that has been traditionally used in the manufacture of porcelain. A SSC mix prepaid with the replacement of cement by metakaolin in different ratios (5%, 10%, 15% and 20%). Slump flow and V- Funnel time increase with increase in the percentage of metakaolin and mechanical properties of SCC like Compressive strength, split tensile strength and elastic modulus of SCC decreases with increases in percentage of metakaolin at the age of 7 days and 28 days but increases with increases in percentage of metakaolin at the age of 90 days.

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. 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%.

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.

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.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

powder will not have the same effect at 28 day.
2. MATERIALS AND ITS PROPERTIES
The cement used in this specimen is ordinary Portland cement of 53 grade and the specific gravity is 3.14. The
initial and final setting times were found as 30 and 356 min respectively. The size of coarse aggregate used was 12.5
mm. The specific gravity of it is 2.73. Fine aggregate used was river sand passing through IS sieve 4.75 mm. As mineral
admixture Fly ash was used in this work. The cement is replaced with 5%, 10%, 15% and 20% by weight of cement. To
improve the workability of concrete Conplast SP430 (2% by weight of cementitious material had been used). To make
the concrete as more workable with self compacting character, chemical admixtures of Viscosity Modifying Agent
(VMA) Glenium Stream 2 of 0.5% by weight of cementitious material was used. Poly Ethylene glycol (PEG) was used
for internal curing (0.5% by weight of cement.) Mix designs of Self compacting concretes were developed by means of
trail mixes based on the guidance given in EFNARC. Standard 150mm cube was produced. Typical Trail mix for Self-
compacting Concrete is shown in Table 1.
3. WORKABILITY OF SCC
Filling ability, passing ability and segregation resistance are the requirements for judging the workability criteria
of fresh SCC. These requirements are to be fulfilled at the time of placing of concrete. Typical Trail mix and workability
property for Self-compacting Concrete are shown in TABLE 1.

4. ANN FOR EVALUATING DESIGN MIX
The results of experimental data include 17 data sets, which was collected experimentally. The compressive
strength of SCC at 28 days was determined by the compressive strength machines. The data were randomly divided into
a training phase (6 data sets), testing phase (6 data set), and validation phase (5 data set). For this compressive strength of
SCC at 28 days modelling problem the obvious inputs are the component contents of concrete, including cement, coarse
aggregate, fine aggregate, fly ash, and chemical admixture. That is, the ANN investigated in the developing has seven
units in the input layer and one unit in the output layer. The values of ANN parameters considered in this approach are as
follows: number of hidden layers = 1; number of hidden neurons = 1, 2, 3, … and 20; learning rate = 0.001, 0.05, 0.01,
0.1, 0.25 and 0.5; momentum factor = 0.01; and learning cycles (epochs) = 1000 which each cycle covers the entire
database available for training. Training function used is TRAINLM and adaption learning function is LEARNGDM.
Transfer function is TANSIG. The input and output (strength) details are feed in the ANN Tool box. It is trained and then
is simulated. The process is given in fig 6 to 10.

6. DISCUSSION ON RESULTS
From the results we can able to retrieve the following conclusions:
6.1. Discussion on Chemical Admixtures
Out of 18 Trails trail 12 and trail 13 gives the bad strength. This is because of increasing the VMA and PEG to
1%. As it is raised the settling time also increases and thereby the hydration process slows down giving raise to decrease
in compressive strength.
SEM and TEM analysis were performed on the concrete specimen having High and Low strength i.e., on trail
12 and Trail 18. The beam was casted for the mix of trail 18 which gave the satisfactory load carrying capacity and
deflection.
6.2. Discussion on Workability
All the trails satisfy the recommendations of workability tests as per EFNARC Specifications.
Trail 1, trail 8 and trail 10 have satisfactory slump results which gives 7.5% lower than slump value of trail 18. Trail 1
and trail 13 is about 40 % lower in V-Funnel tests comparing with trail 18.
The slump value and V-Funnel results of trail 2 gives about 10% and 36.3 % lower respectively to the values of trail 18.
For the trail 3 the slump value is about 7% higher than the value of trail 18. A trail 3, 4 and 5 has the same V-Funnel
values as that of the values of trail 18. For L-Box tests the trails 3, 10 and 12 is 13.5% lower than value of trail 18. The
value of U-Box test for trail 3 is 7.7% lower than trail 18.
Trail 4 and trail 6 does not satisfy the slump flow value as specified in EFNARC Specifications. But those satisfy the
other workability test results. V-Funnel result of trail 6 and trail 16 is 9% lower than trail 18. The L-Box test value of
trail 4 is about 4.2% lower and trail 6 is 5% higher to the test results of trail 18. The U-Box value of trail 4, trail 10 and
trail 14 is 7% higher than the value of trail 18.
The trail 5, trail 7 and trail 14 have the slump value 13% lower than the slump value of trail 18. About 4% higher L-Box
test result than trail 18 and Trails 5, 13 has U-Box test results which are about 15.3% lower than the trail 18.
For the trail 6 and trail 17 have the same U-Box values and about 4% lower than the value of trail 18.
The trail 7, trail 9 and trail 17 has the same V-Funnel tests and about 10% lower than trail 18 and L-Box tests of trail 7
and trail 8 is about 5.2% lower than trail 18. The U-Box test result of trail 7 is about 11.5% lower than trail 18.
Trails 8 and Trail 15 has 20% lower slump value as compared with the slump value of trail 18. Similarly trail 8 and trail
16 has U-Box value of about 23% lower than trail 18.
Trail 9 has slump value, L-Box and U-Box tests results as 3.4% lower, 7.3% lower and 13.3% higher respectively to the
workability results of trail 18.
Trail 11 has slump value, V-Funnel, L-Box and U-Box tests results as 8.9% lower, 16.6% higher, 20% lower and 3.7%
higher respectively than the workability results of trail 18.
The Slump value and U-Box test results of Trail 12 is about 3.3% higher and 42.3% lower than the trail 18.
Trail 13 and Trail 17 have slump value of about 6.2% lower and L-Box value of trail 13 is about 9.4% lower than trail
18.
Trail 14 and trail 17 have L-Box test value of about 6.3% lower than trail 18.
Trail 15 has slump value, L-Box and U-Box tests results as 5.8% higher, 15.8% lower and 19.2% lower respectively than
the workability results of trail 18.
The slump value and L-Box value of trail 16 is about 8.2% and 2% respectively higher than the test results of trail 18.

6.3. Discussion on Compressive strength
The compressive strength of trail 1, trail 4 and trail 13 is about 50% lower than the target strength achieved in
trail 18.
The compressive strength of trail 2 and trail 16 is about 33% lower than strength achieved in trail 18. Comparing the
compressive strength, trail 3 and trail 14 is about 39.5% lower than the strength achieved in trail 18.
Trails 5, 7, 11 and 17 has lower the compressive strength of about 27% compared to the compressive strength achieved
in trail 18.
Trail 6 and trail 10 has compressive strength of about 22.5% lower than the strength achieved in trail 18. Trails 8 and
trail 15 has compressive strength of about 12.5% lower than strength achieved in trail 18.
The compressive strength of trail 9 is nearly to the target compressive strength achieved in trail 18 which is about 8.7%
lower. The lower compressive strength achieved in trail 12 is about 68.75% compared to trail 18.
Trail 18 is our expected result which achieved the compressive strength of about 35N/mm2
.
6.4. Discussion on ANN
The rules obtained by the ANN models are consistent with those by laboratory work. In addition, these
reasonable results indicate that the trained ANN models exhibit good performance. Conclusions drawn from the output
conform to some rules on concrete mix proportioning. To some extent, the ANN models prove reasonable and feasible.
The compressive strength and flexural strength of analytical results satisfactorily matches with the experiment result.
6.5. Discussion on SEM and TEM Images
From Fig 13 and Fig 14, high strength (HS) self-compacting concrete samples have shown smaller physical
interface micro-cracks than low strength (LS) self compacting concretes, which meant that HS SCC had better bonds
than LS concrete, between aggregate and cement. This explains the increase in tensile and compressive strength for the
HS self-compacting concrete compared to the LS concrete. As mentioned earlier, a better bonding due to the smaller
physical interfaces in HS SCC increased the percentages of fractured aggregate compared to LS concrete.
Fig 15 shows the TEM Images in which the particle size and its distributions are clearly pictured. The dark
coloured particle is fly ash is closely arranged. The streams of PEG are also seen which is responsible for internal curing.
7. CONCLUSION
i. From the results, Replacement of fly ash as admixture satisfies all the tests such as Slump flow test, V – Funnel, U
– Box method and L – Box method.
ii. In this research, ANN’s model for evaluating the compressive strength of SCC was developed. The study suggests
that the use of ANNs has several significant advantages over other conventional methods. The results of
compressive strength of SCC at 28 days obtained from the developed computer program were compared with
results from experimental studies. The comparisons of results indicate good agreements.
iii. Optimum percentage of chemical admixtures such as SP, VMA and PEG was found as 2%, 0.5% and 0.5%
respectively exceeding which gives low strength and higher setting time.
iv. The optimum dosage of PEG400 for maximum strengths (compressive and flexural strength) was found to be
0.5% for M40 grade of concrete.
v. The deflection of beam is about 4.52 mm which carries the load to about 155 KN.
vi. Self-curing concrete is the answer to many problems faced due to lack of proper curing.
vii. From SEM and TEM analysis it is clear that the high strength of concrete is due to better bonding between the
concrete ingredients.
viii. ANN models attain good prediction accuracy. Some effects of concrete compositions on strength are in
accordance with the rules of mix proportioning. Consequently, the application of ANN models to concrete
strength prediction is practical and has a good future.
ix. This study of Artificial Neural Network model will provide an efficient and rapid means of obtaining optimal
solutions to predict the optimum mix proportions for specified strength and workability for sustainable SCC. The
application of ANN in the field of SCC mix design is very appropriate in order to preserve and disseminate
valuable experience and innovation efficiently at reasonable cost.
