MSDRAM: Multivalued Sequence Storage of Random Access Memory Using DNA Technology

Tamanna Tabassum — Fri, 10 Jan 2025 00:00:00 +0000

The rapid growth in data generation demands innovative solutions for efficient storage and retrieval, far beyond the capabilities of traditional silicon-based Random Access Memory (RAM). DNA-based storage systems have emerged as a revolutionary approach, leveraging DNA's intrinsic properties such as high density, stability, and scalability. Unlike binary encoding, ternary RAM leverages the quaternary nature of DNA bases to represent multivalued data, thereby enhancing storage density and computational efficiency. This technology achieves unprecedented storage densities by mapping multivalued data to synthetic DNA sequences while implementing advanced biochemical techniques for storage. This paper introduces MSDRAM (Multivalued Sequence Storage of Random Access Memory), a novel architecture utilizing DNA technology to overcome the limitations of conventional storage systems. This proposed research sets the foundation for hybrid storage architectures, combining the strengths of molecular and silicon-based technologies to meet future computational demands. The proposed architecture of multivalued SDRAM demonstrates that it achieves a storage density of a single petabyte per gram of DNA, detailing its encoding unit, DNA-based storage medium, and access mechanisms that significantly outperform traditional RAM and binary-based DNA RAM in capacity and heat efficiency. This research highlights the potential of DNA technology for scalable, energy-efficient memory systems and addresses the challenges of heat, speed, and environmental sensitivity.

The textile sector is one of the most important and fifth largest industrial sectors in the world. Textile sector has created Job opportunity for Millions of workers around the world. The apparel industry plays a great role in economy, employment, investment and revenue all around the world. Textile recycling is a procedure that transforms old or unwanted textiles into new products. This helps to decrease the amount of textile wastage and save assets. Over the last few decades the rate of both pre- and post-consumer textile waste generation has increased significantly. Textile recycling involves reprocessing post-industrial or post-consumer textiles into new products, the term recycling refers to the conversion of textile waste into something approximating the same value. Textile recycling generally includes mechanical and/or chemical processes that turn textile fabrics back into their fiber components to then be remanufactured into fabrics. Post-consumer waste results in lower-quality recycled fiber due to degradation during wear, therefore, only pre-consumer waste is typically recycled mechanically. A circular economy can assist by the development of right choices in the design of products, selection of resources, production, retailing and consumption phases and ultimately in the end of life of the products. Worldwide, 75% of textile waste is landfilled, while 25% is recycled or reused. Landfilling of textile waste is a prevalent option that is deemed unsustainable. Promoting an enhanced diversion of textile waste from landfills demands optimized reuse and recycling technologies various textile reuse and recycling technologies are available and progressively innovated to favor blended fabrics. This Paper highlights the process of mechanical and chemical recycling of Textiles. Benefits of circular economy and how to overcome the Challenges of Circular Economy. Also, will presents the sustainability and efficiency of the Bangladeshi textile industry.

Evaluation of the Agro-Ecological Sustainability of the Banana Production System: The African Food Company Case

The sustainability of agricultural activity, from production to marketing, has been discussed since the twentieth century until the present day. The present study aimed to evaluate the state of sustainability of the irrigated fruit agroecosystem (banana), as in the case of The African Food Company (TAFC). Exploratory and descriptive methods were used to assess the environmental, economic and social dimension of TAFC's sustainability. It was noticeable that the agroecosystem is environmentally sustainable despite having presented an indicator in a critical state (energy consumption). The economic dimension presented sustainable development indices (SDI S3) ranging from stable to excellent, which suggests that the agroecosystem contributes to the guarantee of its self-sustenance, as well as to the leverage of the local and regional economy. The social dimension presented indices ranging from stable to excellent, with only a low index in the level of education. In short, TAFC has a stable sustainability index, as it presents resilient, productive practices with a level of equity.
