In the digital era, safeguarding sensitive information has become more critical than ever. One prominent method for securing data is steganography, which involves concealing a message within an unassuming cover medium, such as an image, to avoid unwanted attention or interception. Unlike encryption, which makes data unreadable, steganography hides the very existence of the message, making the communication covert and imperceptible to the uninitiated eye.This study illustrates a simple and effective technique of text steganography using Python's OpenCV library, a tool adept at image manipulation. The process unfolds in several straightforward steps, beginning with the conversion of the chosen text message into a binary format, a language that is innately understood by computers. Following this, the binary message is intricately woven into the least significant bits (LSBs) of the picture's pixel color channels, a technique which cleverly conceals the message without altering the image's visible properties. To retrieve the concealed message, a reverse process is employed, where the hidden binary bits are extracted from the image and then translated back into its original text format, using ASCII character codes.This method represents a user-friendly approach to steganography, offering a seamless way to secure data transmission by embedding information within an image in a manner that remains both covert and imperceptible, hence promising a robust solution against potential cyber threats.

Water is a critical component in the concrete mix, contributing to its workability and hydration process. Adequate water content is necessary for the proper mixing, placing, and curing of concrete. In areas with lower water availability, managing water in concrete becomes even more crucial, Self-curing concrete is therefore recommended as it reduces the amount of water used during construction process. Concrete is a formulated by mixing cement, fine aggregate, coarse aggregate, and water to produce a cohesive material. The important constituents in concrete is aggregate because it improves the strength and stability of concrete while reducing shrinkage. To conserve aggregate, it is vital to identify substitute aggregate to replace coarse aggregate.

The optimized mass transfer coefficient was achieved at a rotational speed of 800 rpm and a gas flow rate of 0.23 kg/m²s. According to the ANOVA analysis, the gas flow rate was determined to be insignificant, whereas the rotational speed was found to be significant at a 95% confidence interval.

Concrete, known for its versatility and durability, is the material for construction that is most commonly utilised worldwide, comprising key ingredients such as cementitious materials, fine aggregate, coarse aggregate, and water. However, the growing demand for construction has necessitated the exploration of alternative materials that can replicate the performance of conventional components. This study focuses on the development of M-50 grade concrete using innovative substitutions to enhance sustainability and performance. The coarse aggregate is partially replaced with Bethamcherla stone in proportions of 10%, 20%, 30%, 40%, and 50% by weight. This stone, known for its unique characteristics, offers a potential alternative to traditional coarse aggregates, with an aim to improve resource efficiency. In addition to Bethamcherla stone, a self-curing agent, Polyvinyl Alcohol (PVA), is incorporated into the mix at 0.03%, 0.06%, 0.12% and 0.24% by weight of cement. PVA, known for its moisture retention capabilities, enhances the curing process by minimizing external water requirements, which is particularly beneficial in areas facing water scarcity. Furthermore, the study incorporates 10% silica fume, a highly reactive pozzolanic material, as a partial replacement for cement. Silica fume contributes to the development of a denser concrete matrix by improving the microstructure, ultimately increasing the concrete's compressive strength and durability. To evaluate the performance of this modified concrete, both fresh and hardened properties are analyzed. Fresh properties, such as workability and slump, are tested to ensure the concrete mix remains practical and easy to handle during placement. Hardened properties, including compressive strength and split tensile strength, are measured after 28 and 90 days of curing. These tests are crucial for understanding how the incorporation of Bethamcherla stone, PVA, and silica fume affects the long-term strength and performance of the concrete. This research aims to contribute to the development of sustainable, high-performance concrete by addressing key challenges such as resource conservation, water management, and
