Microbial engineering strategies for synthetic microplastics clean up: A review on recent approaches
Get PDFMicroplastics are the small fragments of the plastic molecules which find their applications in various routine products such as beauty products. Later, it was realized that it has several toxic effects on marine and terrestrial organisms. This review is an approach in understanding the microplastics, their origin, dispersal in the aquatic system, their biodegradation and factors affecting biodegradation. In addition, the paper discusses the major engineering approaches applied in microbial biotechnology. Specifically, it reviews microbial genetic engineering, such as PET-ase engineering, MHET-ase engineering, and immobilization approaches. Moreover, the major challenges associated with the plastic removal are presented by evaluating the recent reports available.Author, Dr. Vinay Kumar is thankful to Saveetha Institute of Medical and Technical Sciences (SIMATS), Chennai, Thandalam-602105, India for providing support to carry out the research work. In addition, we are thankful to Prof. Sathyanarayana N. Gummadi for providing his valuable inputs for improvement of the manuscript.Peer reviewe
A critical assessment of technical advances in pharmaceutical removal from wastewater – A critical review
Get PDFUse of pharmaceutical products has seen a tremendous increase in the recent decades. It has been observed that more than thirty million tons of pharmaceuticals are consumed worldwide. The used pharmaceutical products are not completely metabolized in human and animal body. Therefore, they are excreted to the environment and remain there as persistent organic chemicals. These compounds emerge as toxic contaminants in water and affect the human metabolism directly or indirectly. This literature review is an endeavour to understand the origin, applications and current advancement in the removal of pharmaceuticals from the environment. It discusses about the pharmaceuticals used in medical applications such diagnosis and disease treatment. In addition, it discusses about the recent approaches applied in pharmaceutical removal including microbial fuel cells, biofiltration, and bio nanotechnology approaches. Moreover, the challenges associated with pharmaceutical removal are presented considering biological and environmental factors. The review suggest the potential recommendations on pharmaceutical removal.The corresponding author Prof. Vinay Kumar is thankful to all the co-authors for their collaborative efforts in writing this paper.

Subsystem Verification & Analysis of Intellectual Property of Arm® Cortex®-A65AE Architecture
No full textThe development of autonomous vehicles is accelerating rapidly, creating significant challenges for advancing integrated circuits within the automotive sector. One primary challenge is ensuring devices' functional safety without relying on backup or redundant circuits. Verification involves comparing a product’s design against its specifications to ensure that the design and the produced items meet customer requirements and can be reliably delivered. Errors, which occur randomly and can originate from various modules on the SoC, must be meticulously managed to prevent potentially life-threatening situations. This study presents the IP alongside its verification process and coverage analysis.
Verification teams face obstacles in verifying bus performance due to increasing design complexity and constrained development timelines. They need faster execution times, straightforward test bench creation, and efficient test pattern generation. Renesas encountered similar challenges in assessing bus performance in their chips, particularly in latency and bandwidth over time. To address these issues, Renesas utilized Cadence tools and implemented operational flows integrating AVIP and ATP, employing Palladium to reduce prolonged emulation times.
The Arm Cortex A65AE Architecture is a power-efficient, mid-range, throughput-oriented, Simultaneously Multithreaded (SMT) architecture that implements the AArch64 execution state of the Armv8-A architecture within the Dynamic IQ Shared Unit (DSU) cluster. It does not implement the AArch32 execution state of the Armv8-A architecture. As an SMT core, the Cortex A65AE supports two execution threads per core, with each thread functioning as a separate architectural Processing Element (PE) and maintaining a complete copy of the architectural state. This simultaneous multithreading allows the Cortex A65AE to issue and execute instructions from both threads concurrently within the same cycle. Software perceives a thread on the Cortex A65AE, in the same way, it views a core in a traditional single-threaded, multi-core processor, enabling existing software for single-core and multi-core systems to run unmodified on the Cortex A65AE Architecture
