The turning process in hard materials has been way more used in the last few years because of the demand to reduce the manufacturing cost. This research analyzes the superficial roughness evolution in mixed ceramic tool`s wear used to turn ABNT 52100 hardened steel. This study has the objective to find the major reasons that influence the flank wear in ceramic insert and analyze how this wear influences the samples superficial roughness. In the turning process the variables cutting speed (Vc), feed (f) and machining depth (ap) were changed during the tests and analyzed their influences in superficial roughness. The experiments show that the greatest tool`s wear, for the variables used, was because of the forward speed. In the superficial finish study the only thing which has a great impact in average roughness (Ra) was the forward speed that when elevated has increased the average roughness. Meanwhile the vibration excess, caused by the machine`s low hardness, mainly for the several cutting properties, caused damages to the cutting tool that helped to increase the roughness rate while the flank wear also advanced.

IMPACT OF URBANIZATION ON SOCIAL STRUCTURES: A CASE STUDY OF ROHTAK DISTRICT

2025-09-15T12:08:40+00:00

Urbanization has significantly transformed social structures across the globe, influencing various aspects of life such as family dynamics, community interactions, economic participation, and cultural practices. This study explores the impact of urbanization on the social fabric of Rohtak district, Haryana, with a focus on changes in societal norms, mobility, and social hierarchies. Using a mixed-methods approach, this paper analyzes demographic trends, shifts in employment patterns, and alterations in family structures and social interactions due to urban expansion. The research finds that urbanization in Rohtak has led to increased migration, particularly among youth, which has affected traditional family systems, and has contributed to the rise of individualism while challenging collective cultural practices. Additionally, the study highlights the role of infrastructure development and access to education in reshaping social inequalities, with urban areas exhibiting greater socio-economic mobility compared to rural regions. The findings provide insights into the broader implications of urban growth on local social systems, contributing to discussions on sustainable urban planning and its social consequences.

In technologically advancing world, financial transactions in many fold and in several aspects need to be done fast. For this purpose, digital payments come into rescue and helps eliminating the need for physical cash. With rapid advancements in technology, digital payments have become the backbone of modern economies. In India, Tamil Nadu has emerged as a leading state for digital payments. To examine the role of digital payments in enhancing Chennai’s economic growth, the study adopted descriptive and causal research design. Primary data from 50 consumers and business people in Chennai were collected through questionnaire. The study suggests, a majority of respondents view digital payments positively interact economic growth. Nearly half the respondents trust digital payments, while a significant portion remains unsure, highlighting the importance of improving security features and user confidence in digital payments. The study suggests a strong consensus that digital platforms significantly contribute in connecting urban and rural economic activities, facilitating more inclusive growth in Chennai's outskirts, and payments are becoming increasingly popular among street vendors and small merchants. The UPIs are expected to play a crucial role in shaping the future of digital payments in Chennai, with mobile wallets and contactless payments also contributing to this trend. In sum, the research findings highlight a strong preference for digital payments in Chennai.
