Therefore, the aim of this study is to characterize the wind profile for potential energy in Abidjan, Man, Bouaké and Korhogo of Côte d’Ivoire using satellite data. Wind speed and direction data from Copernicus Centre from 2015 to 2022 are used for these major cities. The frequency method is used to build wind rose and power density formula to estimate the potential energy for each city, at ground level (10 m) and in particular level at 100 m and 500 m. The results showed a slightly wind speed and direction variation from 2015 to 2022. This suggests that wind has a seasonal (wet and dry) evolution over the year. However, wind speeds increase for each city with the altitude. The higher average wind speed is observed in Abidjan with a power density of 58 W/m². The lower wind speed and power density are observed in Man, Bouaké and Korhogo. So, the coastline of Côte d’Ivoire has the higher wind energy resource than the inland regions of the country.</div></div>","PeriodicalId":16205,"journal":{"name":"Journal of King Saud University - Science","volume":"36 11","pages":"Article 103579"},"PeriodicalIF":3.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143153528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prolonged administration of uric acid lowering drugs have multiple side effects. Objectives: To investigate the antioxidant and anti-gout properties of iron oxide nanoparticles in hyperuricemic gouty mice. Methodology: Sol-Gel precipitation technique was used for chemogenesis of Iron oxide nanoparticles by using Ferrous Chloride (FeCl2) and Ferric chloride (FeCl3). Characterization was carried out by X-ray diffraction, SQUID magnetization, scanning electron microscopy(SEM) and energy-dispersive X-ray spectroscopy(EDX). Monosodium Urate crystals (MSUC) induced gout into the ankle joint of the mice. Iron oxide nanoparticles were orally administrated to the mice. To study the impact of Iron oxide nanoparticles biochemical analysis like total protein, antioxidant activity, and ankle diameter were conducted. Results: Results showed that oral administration of iron oxide nanoparticles had a beneficiary impact on gouty mice. The antioxidant activity were significantly improved by increasing levels of thiobarbituric acid reactive substance and reactive oxygen species in treated group with 250 mg/kg of body weight of iron oxide nanoparticles. Ankle diameter and levels of total protein were also reduced in treated groups. Conclusion: Current research indicates that Iron oxide nanoparticles have antioxidant as well as anti-gout effects in gouty mice. These results provide credence to the possibility of using Iron oxide nanoparticles as a gout alternative treatment. The potential therapeutic uses of iron oxide nanoparticles in human patients require more investigation.</div></div>","PeriodicalId":16205,"journal":{"name":"Journal of King Saud University - Science","volume":"36 11","pages":"Article 103556"},"PeriodicalIF":3.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143152548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed that the germination process led to a significant increase (<em>p</em> ≤ 0.05) in the content of phenolic, flavonoids, and antioxidat activity (%) compounds following the 72-hour germination compared to samples from ungerminated soybeans.
