 Abstract

Driver fatigue is a major cause of road accidents worldwide. Studies suggest that drowsy driving contributes to nearly 20% of serious road crashes. This project proposes a preventive approach: an Anti-Sleep Safety Alarm using Arduino Uno. The device monitors eye movements using an infrared (IR) sensor and activates an alarm when signs of drowsiness are detected. With increased urbanization, long working hours, and vehicular congestion, it becomes imperative to provide technological assistance to drivers to avoid fatigue-related mishaps. The primary motivation behind this system is affordability, ease of use, and effectiveness. As compared to high-end systems based on EEG, camerabased image processing, or AI-based facial analysis, our solution leverages basic electronic components to deliver a robust mechanism. This research details the system design, implementation, testing, and potential for real-world deployment.

 Abstract

A fingerprint is impression made by the frictional ridges of the fingers on various surface such as porous, nonporous and semi porous. Being one of the useful and robust forensic evidence fingerprints have been widely recognized as the primary human identification tool in forensic investigation. Latent or invisible prints are commonly found at the scenes of crime and thus require the use of visualization methods. The currently available fingerprint visualization powdered methods are chemical with toxic and potential health hazards are. This study proposes a cheap and relatively fingerprint powder from drumstick skins. The findings revealed that drumstick skin powder is capable of visualizing latent fingerprint on porous, non-porous and semi porous surfaces. The latent fingerprints enhanced by drumstick skin powder showed better visualization. It is a non-toxic, safe and easily available powder.

 Abstract

This study investigates the influence of lubricant viscosity on the vibration behavior of rolling element bearings through a controlled experimental analysis. Using a custom-built test rig, cylindrical roller bearings (NJ306 ECJ) were subjected to three lubricant grades (NLGI 1, NLGI 2, and NLGI 3), three loads (3 kg, 6 kg, and 9 kg), and three rotational speeds (300 rpm, 600 rpm, and 900 rpm). Vibration responses were measured using a Fast Fourier Transform (FFT) analyzer to quantify frequency spectra and amplitudes. Results indicate that NLGI 2 grease consistently exhibited the lowest vibration amplitudes across all conditions, demonstrating superior damping and stability compared to NLGI 1 and NLGI 3. Higher viscosity (NLGI 3) led to increased vibration due to inadequate penetration, while lower viscosity (NLGI 1) showed limitations under high loads and speeds. These findings highlight the critical role of optimal lubricant viscosity in minimizing vibration and enhancing bearing longevity, offering practical insights for machinery design and maintenance. The study contributes to tribology by providing empirical evidence to guide lubricant selection in industrial applications

 Abstract

Around the world, nanotechnology is being promoted as a technological revolution that will help resolve an array of problems. According to the current hype, nanotechnology promises to provide new ways of solving some of Africa's chronic challenges such as treating tuberculosis and malaria, making water drinkable, conserving food, and diversifying energy sources, among other hosts of applications. However, the potential risks and social implications of this new technology are not often discussed nor addressed. The overall level of awareness and capacity to address these issues remains very low, in both civil society and government, and prevents these actors from playing their social role in ensuring the public good. Research on nanotechnology, and increased commercialization of products containing engineered nanomaterials (generally called nano products), are currently happening in Africa (e.g., in South Africa, Sudan, Kenya, Zimbabwe, Egypt, Algeria). In several African countries, nanotechnology has been declared a strategic sector of scientific and technological development. In addition, graduate courses on nanotechnology have been initiated in some countries, such as South Africa, Egypt, and Algeria. Even though potential health and environmental risks of engineered nano- materials are scientifically documented and numerous uncertainties remain, the public funds dedicated to evaluating these risks are extremely low. As a consequence, the current policy in regards to this technology is far from precautionary as the products enter the market unregulated and unlabeled, neither guaranteeing the safety of the product, nor the information to the consumer. The Present review paper highlighted sustainable development Socio economic transformation through Nano Science technology various issues and challenges at global level policy framework

 Abstract

The increasing volume of organic waste in urban areas necessitates an intelligent waste management system to enhance efficiency and sustainability. This study examines the logistic framework of organic waste management using smart dustbins integrated with IoT, AI-driven waste classification, and automated collection strategies. By leveraging sensor technology, real-time data analytics, and optimized waste transport, smart dustbins can revolutionize traditional waste disposal methods. Smart dustbins monitor waste levels, segregate biodegradable materials, and transmit data to waste collection units, enabling predictive waste collection scheduling and fuel-efficient route planning. The research underscores the importance of public-private collaboration, smart city integration, and sustainable policy frameworks to promote efficient organic waste logistics. By combining automation, data intelligence, and circular economy principles, smart waste management systems can minimize carbon footprints and foster eco-friendly urban environments. Proper waste management is essential for environmental sustainability. This study examines the municipal solid waste management and disposal methods in Yavatmal district, Maharashtra, India, analyzing waste composition, characteristics, and associated environmental concerns. Primary data was collected through structured questionnaires from randomly selected populations in areas with significant waste findings reveal that both designated and non-designated waste dumps remain unattended for prolonged periods, leading to road encroachments, pollution, and aesthetic degradation of the metropolis Findings reveal that both designated and non-designated waste dumps remain unattended for prolonged periods, leading to road Encroachments, pollution, and aesthetic degradation of the metropolis.

 Abstract

In the digital age, the evolution of marketing strategies has significantly influenced consumer behaviour, fostering a phenomenon known as `a cycle of continuous and often impulsive online purchasing`. The present study explores the factors contributing to spiral consumption among IT professionals in Infopark, Kochi, Kerala, with a specific focus on the influence of digital marketing. Based on the data collected from 63 IT professionals through purposive sampling, the research employs Exploratory Factor Analysis, Correlation Analysis, and Multiple Regression to identify and analyse psychological, technological, economic, social, and personal factors impacting spiral consumption. The findings reveal a significant correlation between spiral consumption and continuous consumption cycles, with digital marketing elements such as personalised ads, social media influence, and convenience playing key roles. The study points the need for ethical digital marketing practices and enhanced consumer awareness to mitigate the financial and psychological risks associated with uncontrolled online consumption.
