This document summarizes a study on the influence of thermal distress on the flexural strength of laminated cement composites. Specimens with 1-5 reinforcement layers were subjected to 0-120 thermal cycles consisting of 24 hours at 110°C and 24 hours at 15°C. Control specimens were cured similarly but at 15°C. Testing found that flexural strength increased with cycles for all specimens, and strengths were higher for thermally distressed specimens compared to controls. Thermal distress altered composite behavior and led to increased strength.
Annealing Response of Aluminum Alloy AA6014 Processed By Severe Plastic Defor...IRJESJOURNAL
Abstract: In this paper the study of micro structural stability during annealing with respect to time of conventionally grains (CG) and ultrafine-grained (UFG) of Aluminum AA6014 i s carried out. It has been observed that, the effect of the second phase magnesium-silicon particles in the CG and UFG AA6014 samples leads to a rapid hardness which increases from 40HV10 to 70HV10 within 7 days. Artificial aging shows that the material hardness even increased after 20 hours of annealing at 180°C. In total 30 hours of annealing, the hardness arrives at its maximum and then reduces due to the formation of Mg2Si precipitates, which rise in size and change their coherency. The precipitates cannot efficiently pin the dislocations and act as barriers to the dislocation motion which indicate an overall decrease in the hardness. It also has been found that the ultrafinegrained AA6014 alloy loses its thermal stability at approximately 200°C and recrystallized at 300°C. Thermal stability is strongly dependent on the material purity, second phase particles and/or oxide particles which may break up during rolling and lead to some dispersion strengthening.
Abstract: Bagasse is a cellulose fiber remaining after the extraction of the sugar-bearing juice from sugarcane. It is a valuable byproduct in sugar milling and is often used as a primary fuel source due to its high calorific value required to supply most energy requirement for most sugar factory operations. The burning of baggase leaves solid black particles known as sugar cane baggase ash (SCBA). Utilization of this waste material as partial replacement of cement in concrete provides a satisfactory solution to some of the economical, environmental and concerns associated with waste management. SCBA is normally disposed as landfills, exposure to these dusts causes chronic lung condition and its application on agricultural lands results to heavy metals concentrations in soils. It has been reported by several researchers that SCBA has intrinsic characteristic such as high content of silica in the form of quartz. This research mainly focused on SCBA disposed as solid wastes from Nzoia Sugar Company, Bungoma County in western Kenya. The research design adopted was Experimental. Granulometric indices of SCBA were determined through sieving the samples and weight retained. Strength Activity Index test, was used to assess the Pozzolanic activity of SCBA. Results showed that SCBA exhibits high Pozzolanic activity, hence can be used as a substitute cementitious material.
The document presents the results of an experimental study on the effect of controlled temperature ranging from 27°C to 42°C on the compressive and flexural strength of M20 grade concrete. Specimens of different sizes were cast and tested at 7, 14, and 28 days. The results show that compressive strength generally decreases with increasing temperature, except at shallow depths where strength peaks at around 33°C. Flexural strength of beams and slabs also decreases with higher curing temperatures. The workability of concrete, measured by slump, decreases as temperature rises.

Effect of die dimension on extrusion processing parameters (animal feed)Wan Ali Akashah Akashah
This study investigated the effects of die nozzle dimensions, barrel temperature profile, and moisture content on properties of extruded distillers dried grains with solubles (DDGS)-based aquaculture feeds and extruder processing parameters. Seven different die nozzles were used to extrude an ingredient blend containing 40% DDGS at three moisture levels (15-25%) and three temperature profiles (100-140°C). Increasing moisture content decreased density and pressure but increased durability and absorption. Higher temperature decreased density and pressure but increased absorption. Larger die nozzle ratios increased density but decreased durability and absorption. Process conditions and extrudate properties are affected by die geometry, temperature, and moisture content.
Preparation and Characterization of Rubber Composites using Sawdust as Fillerijtsrd
The research work aims to prepare, characterize and apply the vulcanized rubber composites by using sawdust as filler. Sawdust was used as filler in the process of preparation of vulcanized rubber composites. The composite of natural rubber sawdust NR SD was prepared by being replaced the percent ratio 100 0 75 25 50 50 and 25 75 parts weight of natural rubber NR with SD vulcanized for rubbery goods. The surface morphology, elemental analysis and thermal degradation of the prepared NR SD composites were determined by SEM, EDXRF and TG DTA, respectively. The physic mechanical properties such as tensile strength tear strength, elongation at break, hardness and abrasive resistance of NR SD composites were determined by standard rubber testing methods. It was observed that the vulcanized NR SD composites were again determined by soaking in the selected organic solvents and oils ethanol, gasoline, diesel, engine oil, and used engine oil . Being used the sawdust as filler, it not only reduces the cost of production for appliances but also it is likely the supply of the maintenance for Green.

The document summarizes a study on the effects of moisture absorption and temperature on the mechanical properties of polymethacrylimide (PMI) foam core sandwich composites. Specimens were immersed in deionized water and sea water at 25°C and 70°C. The results showed that specimens absorbed more moisture at higher temperatures and in deionized water compared to sea water. Exposure to high temperature (70°C) water significantly reduced the compressive and flexural strength and modulus of the composites, with strength reductions of up to 36% and modulus reductions of up to 68%, likely due to plasticization and fracturing of the PMI foam core at high temperatures.

The document evaluates the effect of mixing method on the performance of mortar containing oil. It finds that the mixing method (whether oil is mixed with cement or sand) has only a small effect on the fresh and hardened properties of the mortar. Both mixing methods followed the same trend of inhibited hydration and reduced compressive strength with increased oil content. Specifically, oil increased flow and setting time but decreased density and air content for both mixing methods. Compressive strength was reduced by 75-77% with 10% oil content, irrespective of mixing method. The calorimetry results also showed that both mixing methods followed the same trend of inhibited hydration due to oil incorporation.
Effect of coarse aggregate characteristics on strength properties of highIAEME Publication
This document summarizes a study on the effect of coarse aggregate characteristics on the strength properties of high-performance concrete. The study used two types of coarse aggregates and tested concrete cubes to determine compressive strength at 56 days. The key findings were:
1) Concrete made with Type A aggregate achieved higher compressive strengths, up to 62.5 MPa, compared to concrete with Type B aggregate, up to 28.62 MPa.
2) Type A aggregate concrete had better workability as measured by slump and slump flow tests.
3) Aggregate type can significantly influence the compressive strength and workability of normal concrete mixtures. The highest strengths were obtained using Type A coarse aggregate.
This document investigates the effects of replacing cement with different amounts of fly ash, ranging from 30-70%, on the hardened properties of self-compacting concrete. Testing showed that as the percentage of fly ash replacement increased, the compressive and split tensile strengths of the concrete decreased. A relationship was developed between split tensile and compressive strengths that predicted tensile strengths with an average error of 4.19%. The study concluded that replacing cement with higher amounts of fly ash lowers concrete strengths.

The document summarizes a study on the effects of partially replacing cement with nano-silica and fly ash in concrete. Tests were conducted on concrete mixtures with 20% and 30% fly ash replaced and 1-5% nano-silica replaced to examine the compressive strength and rapid chloride permeability at different curing periods. The results showed that compressive strength increased up to 4% nano-silica replacement and then decreased with further addition. Rapid chloride permeability was reduced with increased nano-silica. Overall, the partial replacements improved concrete properties compared to the control mix without replacements.
Investigation of Tribological Behaviour of GF Filled Peek Composite under the...IJERA Editor
Composite materials have successfully substituted the traditional materials in several light weight and high
strength applications. The reasons why composites are selected for such applications are mainly their high
strength-to-weight ratio, high tensile strength at elevated temperatures, high creep resistance and high
toughness. Therefore minimum Wear of component or part used in machinery is very important factor for the
industry. In this paper the tribological behavior of PEEK (Poly-ether-ether-ketone) composites reinforced by
30% short glass fiber and phosphor bronze were comparatively evaluated on Pin on disc machine. The effect of
three parameters such as temperature, load and sliding distance on Wear loss of PEEK composites reinforced by
30% short glass fiber and phosphor bronze were examined. The detailed mathematical model is simulated by
Minitab 17 and simulation results fit experiment data very well
In this investigation, an effective approach based on Taguchi method, analysis of variance (ANOVA),
multivariable linear regression (MVLR), has been developed to determine the optimum conditions leading to
minimum Wear. Experiments were conducted by varying temperature, load and sliding distance using L9
orthogonal array of Taguchi method. The present work aims at optimizing process parameters to achieve
minimum Wear. Experimental results from the orthogonal array were used as the training data for the MVLR
model to map the relationship between process parameters and Wear. The experiment was conducted on
computerized Pin on Disc machine. It was observed that PEEK 30% Glass Fiber Composite Polymer has
excellent wear resistance compare to Phosphor bronze at elevated temperature.

This document summarizes a research article that examined academic librarians' awareness of the skills required of "new era librarians" in South East Nigeria. It found that librarians have a high level of awareness due to early adoption of ICT. Skills can be acquired through on-the-job training, workshops, seminars, and professional groups. Traditional librarians may be disadvantaged without opportunities to update skills. The document proposes that library schools, training programs, and management support are needed to help librarians adapt to changing roles and digital environments.
The document discusses using regression models and k-means clustering to improve voltage stability in power systems. It begins by introducing the concepts of voltage stability and issues that can cause instability. Regression models are then presented as a way to model the relationship between pre-disturbance operating points and critical voltage stability margins. The k-means clustering algorithm is also described as a method to group inputs and reduce dimensionality for improved generalization. Results show that regression models can approximate stability margins and k-means clustering effectively handles large amounts of data by determining an optimal number of cluster centers. The proposed approach is concluded to analyze the most critical post-disturbance stability margin through regression and clustering techniques.
This document summarizes a research paper on brand loyalty for salt brands in Mysore City, India.

The document evaluates the effect of mixing method on the performance of mortar containing oil. It finds that the mixing method (whether oil is mixed with cement or sand) has only a small effect on the fresh and hardened properties of the mortar. Both mixing methods followed the same trend of inhibited hydration and reduced compressive strength with increased oil content. Specifically, oil increased flow and setting time but decreased density and air content for both mixing methods. Compressive strength was reduced by 75-77% with 10% oil content, irrespective of mixing method. The calorimetry results also showed that both mixing methods followed the same trend of inhibited hydration due to oil incorporation.

Composite materials have successfully substituted the traditional materials in several light weight and high
strength applications. The reasons why composites are selected for such applications are mainly their high
strength-to-weight ratio, high tensile strength at elevated temperatures, high creep resistance and high
toughness. Therefore minimum Wear of component or part used in machinery is very important factor for the
industry. In this paper the tribological behavior of PEEK (Poly-ether-ether-ketone) composites reinforced by
30% short glass fiber and phosphor bronze were comparatively evaluated on Pin on disc machine. The effect of
three parameters such as temperature, load and sliding distance on Wear loss of PEEK composites reinforced by
30% short glass fiber and phosphor bronze were examined. The detailed mathematical model is simulated by
Minitab 17 and simulation results fit experiment data very well
In this investigation, an effective approach based on Taguchi method, analysis of variance (ANOVA),
multivariable linear regression (MVLR), has been developed to determine the optimum conditions leading to
minimum Wear. Experiments were conducted by varying temperature, load and sliding distance using L9
orthogonal array of Taguchi method. The present work aims at optimizing process parameters to achieve
minimum Wear. Experimental results from the orthogonal array were used as the training data for the MVLR
model to map the relationship between process parameters and Wear. The experiment was conducted on
computerized Pin on Disc machine. It was observed that PEEK 30% Glass Fiber Composite Polymer has
excellent wear resistance compare to Phosphor bronze at elevated temperature.

The document discusses using regression models and k-means clustering to improve voltage stability in power systems. It begins by introducing the concepts of voltage stability and issues that can cause instability. Regression models are then presented as a way to model the relationship between pre-disturbance operating points and critical voltage stability margins. The k-means clustering algorithm is also described as a method to group inputs and reduce dimensionality for improved generalization. Results show that regression models can approximate stability margins and k-means clustering effectively handles large amounts of data by determining an optimal number of cluster centers. The proposed approach is concluded to analyze the most critical post-disturbance stability margin through regression and clustering techniques.

Remaining Life Analysis of Boiler Tubes on Behalf of Hoop Stresses Produced D...IJERA Editor
Boiler tube material plays an important role in efficient power generation from a fossil fuel power plant. In order to meet out the gap between fluids to increase heat available per unit mass flow of steam. Waste heat utilization phenomenon is a big challenge on fossil fuel power plants as after use of high grade coal in thermal power plants the efficiency of power plants is not at the level of required value. Clean and efficient power generation with economical aspects is the basic need of growing power generation plants to justify the quality of power and clean power generation. Life analysis technique to calculate remaining life of boiler tubes at critical zones of high temperature requires much attention and is an important hypothesis in research field. Generation of repetitive and fluctuating stress during flow of high temperature and pressure fluid require proper attention on the methodology to be used to calculate the efficiency of system and absorption efficiency of tube material. In this paper complete mathematical analysis of boiler tubes is conducted for calculation of remaining life of boiler tubes, Hoop stress values are calculated and used with mathematical tool to calculate the efficiency. Hoop stress based calculation of efficiency is more reliable and may give more accurate and practical aspects based results.

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.

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 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.
