RECENT ADVANCEMENT IN NANO CELLULOSE AS A BIOMASS-BASED ADSORBENT FOR HEAVY METAL IONS REMOVAL: A REVIEW OF A SUSTAINABLE WASTE MANAGEMENT APPROACH

Rapid industrialization and unplanned urbanization have significantly increased environmental pollution. These human behaviors have resulted in massive waste discharges into the environment. As a result, organic and inorganic contaminants, including heavy metals, have accumulated in surface and groundwater. Heavy metals are highly carcinogenic and deadly. Heavy metal removal from drinking water has always been difficult. Conventional water treatment procedures could be more efficient, wasteful of energy, and generate massive amounts of harmful waste. In this initiative, researchers created a bio-based adsorption technology for removing heavy metal ions from polluted water. Nano celluloses (NCs) as biosorbents have sparked considerable attention due to their unique properties, such as the presence of several -OH groups on their surface, allowing the insertion of chemical moieties, a substantial specific surface area, strong mechanical properties, recyclability, and biodegradability. This review paper goes into great detail regarding the ways of producing Nano cellulose and its essential qualities. Many factors influence the use of NCbased adsorbents in water treatment systems, including synthesis pathways, functionalization of the surface, specific surface area, regeneration capacity, and reusability. Recent advances in bio-sorbent synthesis have prompted using bio-derived NC-based adsorbents in water treatment methods. This study also demonstrates that utilizing the potential for agricultural wastes, specifically sugarcane bagasse (SCB), as a precursor for Nano celluloses represents a sustainable approach, namely the conversion of low-value waste into a specific high-value product and its use in wastewater treatment

UAV Cloud Operating System

Unmanned aerial vehicle (UAV) which is a special case of mobile ad-hoc networks (MANETs) that attracts many researchers as it becomes a scope for both military and civilian applications. Also the trend of cloud computing when it is combined with UAV highlights this field of research in many aspects, but the most significant point of research is the operating system for the cloud. This paper investigates UAV cloud operating system showing the throughput (bits/Sec) for the system implemented when using both Windows and Linux operating systems in order to select the operating system used based on a real scientific results

Maximizing the clinical benefit of radiotherapy in solitary plasmacytoma: An international multicenter analysis

International audienceObjective: Although local definitive radiotherapy (RT) is considered the standard of care for solitary plasmacytoma (SP), the optimal RT parameters for SP patients have not been defined. The aim of this retrospective study is to analyze the effectiveness of various RT doses, volumes, and techniques, as well as to define the relevant prognostic factors in SP. Methods: Between 2000 and 2019, 84 patients, including 54 with solitary bone plasmacytoma (SBP) and 30 with extramedullary plasmacytoma (EMP), underwent RT at six institutions. Results: The overall RT median dose was 42 Gy (range, 36.0–59.4). The median follow-up period was 46 months. Overall, the local control (LC) rate was 96%, while the complete remission (CR) rate was 46%. The 5-year local relapse-free survival (LRFS), multiple myeloma-free survival (MMFS), progression-free survival (PFS), and overall survival (OS) rates were 89%, 71%, 55%, and 93%, respectively. Using an RT dose above 40 Gy was associated with a higher complete remission (CR) rate and a lower rate of local relapse. Modern irradiation techniques were associated with a trend toward a higher LC rate (98% vs. 87% for conventional, p = 0.09) and a significantly lower local relapse rate (6% vs. 25% for conventional, p = 0.04). However, RT dose escalation and technique did not lead to a significant effect on MMFS, PFS, and OS. Univariate analyses identified several patient characteristics as potentially relevant prognostic factors. In SBP patients, systemic therapy administration was associated significantly with MMFS and PFS rates. Conclusion: Using an RT dose >40 Gy and modern RT techniques may improve the local control and reduce the rate of relapse, without a significant impact on survival rates. The addition of systemic therapies may improve the MMFS and PFS rates of SBP patients
