This document summarizes a study on the effect of sintering temperature and porosity on the dry sliding wear behavior of copper-based brake materials. Samples were sintered at temperatures of 850, 900, and 950°C and tested. Scanning electron microscopy revealed that the highest sintering temperature of 950°C resulted in the lowest porosity of 14.04% and lowest wear rate, with a smooth surface formed by iron particles. Higher porosity samples exhibited higher wear rates, with abrasive scratches and delamination flakes observed. The optimal porosity and wear resistance was obtained at 950°C.
IRJET- Experimental Investigation of Wear Rate using Alternating Material for...IRJET Journal
This document experimentally investigates wear rates of materials for bushings used in food mixers. The existing bushing material is gunmetal, which has a high copper content. Testing on a pin-on-disc tribometer shows the wear rate of gunmetal at various loads and speeds. To reduce wear, a composite of brass and 5% molybdenum disulfide is proposed as an alternative material. Samples of the proposed material are fabricated via powder metallurgy and tested under the same conditions as the existing gunmetal. Test results show the proposed composite has a lower wear rate than the existing gunmetal bushing material across all loads and speeds tested.

In this study, the effect of improved microstructure of Al-5.7Si-2Cu-0.3Mg alloys by using semisolid process on hardness and dry sliding wear behaviour were investigated. The microstructures of conventional cast alloy were totally dendritic, while in rheocasting the dendrit-ic transfer to fine globular microstructures after using cooling slope casting. Tribological tests were carried out by using a pin-on-disc apparatus in dry sliding conditions. Wear tests were at low sliding speed 1ms-1 ,applied load at 50N and three different sliding distance (i.e., 1.8Km, 5.4Km and 9Km) respectively. An optical microscope and a scanning electron microscope were used to examine the micro-structure and to understand the wear mechanism on the worn surface of both samples. The results showed that, the wear resistance of rheocast alloy was improved and higher than that those produce by conventional casting. The volume loss of rheocast alloy show reduc-tion more than 18% at 1.8Km and 10% at 9Km compared to as-cast alloy. Moderate wear regimes were appeared in both alloys, accord-ing to the range of wear rate. The friction coefficient had increased due to increase in the contact point between pin and disc materials. The dominant wear mechanism for conventional and rheocasting alloys was adhesion wear and abrasive wear respectively.

This document evaluates the modal damping of graphite/epoxy laminated composites through experimental testing. Graphite/epoxy laminate composite plates of different thicknesses (2mm and 4mm) and fiber orientations (0 and 45 degrees) were fabricated and tested under different boundary conditions (cantilever, two sides fixed, all sides fixed) using an impulse excitation technique. The results show that modal damping decreases with increasing laminate thickness and is sensitive to changes in boundary conditions. Damping was highest for the cantilever boundary condition and lowest for the two sides fixed condition. Evaluation of modal damping through experimental modal analysis provides a simple and effective technique for characterizing damping properties of composite laminates.

Effect of pin profile on friction stir welded aluminum matrix compositesAsif Ali
The document discusses the effect of pin profile geometry on friction stir welded aluminum matrix composites. It finds that a square pin profile produces welds with smaller and finer grains compared to hexagonal and octagonal pin profiles. This leads to improved hardness, tensile strength, and wear resistance due to the relationship between smaller grain size and better mechanical properties. The square pin profile causes less heat input during welding, resulting in less grain growth and better properties compared to the other pin profiles tested. Increasing welding speed and decreasing rotational speed also reduce heat input and improve properties by limiting grain growth during cooling.
The document discusses the influence of solid lubricant emulsions on the surface roughness of hardened steel when machining on a shaper. Three key findings are presented:
1) Surface roughness decreases as the particle size of boric acid solid lubricant increases, from 50μm to 200μm.
2) Surface roughness also decreases as the weight percentage of boric acid increases, from 5% to 20%.
3) The use of a composite lubricant containing boric acid and nano graphite results in lower surface roughness than boric acid alone, due to improved cushioning from the nano particles.

Wear resistance is more in nano composites as compared to the LM13 matrix material.
This document discusses techniques for measuring wear of bulk materials and advanced surface coatings. It begins by defining wear and explaining that wear occurs even in the hardest materials through mechanisms like plastic deformation and brittle fracture. It then discusses that wear testing is important for minimizing component failure in industries. Various wear testing techniques are described, including pin-on-disc testing where a stationary pin is pressed against a rotating disc under a load to simulate different wear modes. Other techniques involve characterizing coatings through hardness testing or evaluating coatings and materials in actual machining tests on equipment. Selecting the appropriate wear test depends on factors like the contact conditions and environment being simulated.

The document discusses the influence of solid lubricant emulsions on the surface roughness of hardened steel when machining on a shaper. Three key findings are presented:
1) Surface roughness decreases as the particle size of boric acid solid lubricant increases, from 50μm to 200μm.
2) Surface roughness also decreases as the weight percentage of boric acid increases, from 5% to 20%.
3) The use of a composite lubricant containing boric acid and nano graphite results in lower surface roughness than boric acid alone, due to improved cushioning from the nano particles.

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.

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.
