 Abstract

Nickel-zinc ferrites are the magnetic materials that shows diverse industrial applications especially in the photo catalysis owing to their magnetic coactivity and eddy current loss with low value electrical resistivity with high value that affects and tailor these soft magnetic nano ferrites structural and morphological characteristics. In existing study, we have synthesized zinc doped nickel ferrites Ni1-xZnxFe2O4 nanoparticles (NPs) with variation in nickel and zinc concentration simultaneously as (x = 0.0, 0.2, 0.4, 0.6 ,0.8,1.0)) via Sol-Gel auto combustion technique. The structural analysis of the NPs was carried out by XRD technique. We compare our results with JCPDS #01-073-1963. From this study we conclude that the synthesized NPs are cubic spinel structure with preferential orientation along the (311) plane. D-spacing for (311) plane varies from 2.48 to 2.53 A0. We have determined the crystallite size using the Debay-Scherer Formula and we observed crystallite size in between the 22nm to 29nm. Investigations by XRD revealed that all the prepared samples demonstrate a pure phase. Alterations in the lattice parameters and micro-strain observed due to introduction of Zn in the crystal structure. Morphology of the synthesized NPs analyzed using the FESEM. We have observed that synthesized NPs are porous in nature. With concentration of nickel and zinc, this porosity varies. Stoichiometry of the NPs was studied with the help of EDS spectra. It confirms the presence of the nickel, zinc, iron and oxygen in the NPs. With change in the concentration, we observed the variation in the atomic % of Zinc and Nickel.

 Abstract

Solar-powered water fountains have gained significant attention due to their eco-friendly nature and sustainability. This paper proposes the design and implementation of a solar-powered water fountain system, which utilizes a Variable Frequency Drive (VFD) to control the water pump's speed, providing energy efficiency and adaptability to fluctuating solar irradiance levels. The system operates without the need for batteries, making it simpler and reducing the maintenance costs commonly associated with energy storage systems. The proposed system directly converts solar energy into mechanical work for the fountain pump by adjusting the motor's frequency to maintain optimal performance. By incorporating a VFD, the water flow can be dynamically controlled based on solar intensity, ensuring consistent operation while minimizing energy waste. This system provides an efficient and reliable solution for renewable energy applications, especially in off-grid locations. Experimental results demonstrate the effectiveness of the system, showing stable fountain operation with variable solar conditions. The paper also discusses the benefits, challenges, and potential for future advancements in such solar-powered systems.

 Abstract

The increasing use of cloud services in healthcare enables cost-effective sharing of Personal Health Records (PHRs) but raises serious privacy and security concerns. To address this, we propose a framework based on Attribute-Based Encryption (ABE), which provides fine-grained, attribute-driven access control over encrypted PHRs stored on untrusted cloud servers. A trusted authority manages key generation, attribute distribution, and access policies, ensuring protection against insider threats and forward and backward access control. Formal analysis using High-Level Petri Nets (HLPN) and performance evaluation shows that the ABE-based system offers an effective and secure solution for sharing PHRs in the cloud.

India is a land full of culture, tradition, and spirituality where every region has its own unique way of connecting with the divine. One thing that beautifully ties many of these practices together is the use of flowers. Whether it's a simple daily offering or a grand festival celebration, flowers are seen as a pure and heartfelt symbol of devotion. Because of this, there's always a strong need for a variety of flowers across the country and, India is also land of rich traditions, where culture and rituals are deeply woven into everyday life especially during weddings and festivals. Flowers play a big role in these events, often used as offerings to deities or for decoration, making them an essential part of our cultural fabric. Because of this, there's always a high demand for different kinds of flowers. But for many farmers, knowing which flowers will grow best in their soil can be a challenge, Though the flower farming has become a popular and profitable branch of agriculture where the demand is been increasing every year, but choosing the right flowers to grow can be slightly difficult. Farmers often struggle with factors like local climate, soil conditions, and changing market demand. This research introduces a farmer friendly Flower Farming Recommendation Application designed to help farmers make smarter and better decisions, were flower By taking in simple inputs like NPK and Ph, values the application, suggests the most suitable flowers to cultivate in a specific region, fertilizer deficiency, irrigation method, market demand and also harvesting type .It uses sensor for data collection and cloud web application to get the suggestions which can be helpful to improve both soil and flower yield.

 Abstract

Aranyaka: Book of the Forest, a graphic novel, has been created by Indian mythologist Devdutt Pattnaik and graphic designer Amruta Patil. Aranyaka means the forest, and narratives written on it explore mysticism and symbolism. They represent the natural progression of the Upanishads. Aranyaka links the Brahmanas' focus on Karma marga and the Upanishads' emphasis on jnana marga. The graphic narrative is an artistic representation of the Vedas and the environment. The novel begins with the cosmic representation and evolution of the planet Earth and unfurls with Yajnavalkya and Katyayni digging forest for more knowledge and searching for their self. This article examines how Aranyaka graphically and narratively articulates the underlying environmental consciousness within Vedic cosmology, revealing how the graphic novel functions as a strong medium for learning and appreciating the ecological knowledge buried in ancient Indian writings. The paper investigates the novel through sacred ecology and mythopoeic vision.
