Utilizing circulation-derived cancer cells to evaluate patients with surgically treated stages I–IIIA NSCLC throughout the preoperative phase
Abstract: Context: When a tumor is considered resectable, surgery is viewed as the primary treatment approach for both early-stage and locally advanced non-small cell lung cancer (NSCLC). One of the most exciting areas of cancer research in the past ten years is liquid biopsy, which offers a practical non-invasive method for cancer detection and tracking. Circulating tumor cells (CTCs) have been linked to a worse prognosis and increased chance of relapse …

Effect of Compressibility on Undrained Bearing Pressure of Circular Footing Resting on Two-Layered Clay
Abstract: The present study aims to investigate the behavior of a circular foundation on layered clay of varying properties. There are several solutions for the bearing capacity of footings on two-layered clays, but none of them considered the compressibility of the strata. An underestimation of the soil bearing capacity is the main cause of failures. The typical difficulty in estimating the capacity of soil is its complicated behavior attributed to the …

Closing the Loop: Innovative Strategies for Circular Economy and Sustainable Waste Management
Abstract: Africa’s growing waste crisis, especially in rapidly expanding cities across Nigeria, has made it increasingly clear that traditional “take–make–dispose” systems can no longer support sustainable development. This paper explores how shifting to a circular economy (CE) can transform waste from a persistent challenge into a valuable resource. Instead of seeing waste as an endpoint, the circular economy model encourages designing products for longer lifespans, rethinking consumption patterns, and recovering materials …
