This study aims to quantify the surface water resources used for sugarcane production in sugar complexes of Ferkessedougou. This is based on the morphological characterization of the river Morrison and Lopkoho dams and on <span>extreme daily flow probability of occurrence estimation using frequency analysis</span> method. The bathymetric survey showed that the Morrison Dam im<span>poundment had a maximum depth of 11.98 m;a water capacity of 11,656,735.5</span> m<sup>3</sup>. For the Lokpoho dam, the reservoir had a maximum depth of 8.82 m, which corresponds to a water volume of 4,354,531.5 m<sup>3</sup>. Nevertheless, the water capacity of these reservoirs is greatly reduced by a large volume of sediment estimated at 1,013,058.96 m<sup>3</sup> for Morrison and 599,740 m<sup>3</sup> for Lokpoho. Statistical analysis of maximum daily flows shows that flows between 73.9 and 100 m<sup>3</sup>/s have the potential to occur every five years at the Route Korhogo Badikaha hydrometric station. The recurrence of the decennial (298 m<sup>3</sup>) and quinquenal (248 m<sup>3</sup>) flows shows the importance of the flood flows of the Bandama River. It also shows that the low water levels of the Bandama are very pronounced. The minimum flow that SUCAF-CI water managers should expect every five years is 1.36 m<sup>3</sup>/s and the ten-year low flow is 2.10 m<sup>3</sup>/s. These results are indicators of water scarcity risks and could guide decision making in the Ferkessedougou sugar complexes.展开更多

槲皮素(Quercetin,Que)作为一种高生物活性的黄酮类物质,疏水性极强,限制其在食品工业中的应用。本研究利用小麦蛋白酶解物(wheat protein hydrolysate,WPH)、Que构建复合纳米颗粒,以甜菜果胶(sugar beet pectin,SBP)作天然复合乳化剂,...槲皮素(Quercetin,Que)作为一种高生物活性的黄酮类物质,疏水性极强,限制其在食品工业中的应用。本研究利用小麦蛋白酶解物(wheat protein hydrolysate,WPH)、Que构建复合纳米颗粒,以甜菜果胶(sugar beet pectin,SBP)作天然复合乳化剂,成功构建了WPH/Que/SBP复合乳液并对其进行性质表征,主要结论如下:WPH对Que具有良好的增溶效果,Que溶解度从8.13μg/mL提升至126.39μg/mL。在乳化包埋的过程中,SBP优异的乳化性能可能有利于其在竞争关系中处于优势地位并弥补WPH乳化性能的劣化,故界面WPH和界面Que含量下降。随着SBP的添加,复合乳液粒径显著下降,中性和酸性复合乳液的表面积平均粒径分别从2.35μm和1.03μm下降至0.56μm和0.76μm。复合乳液表现出良好的短期储藏稳定性和热稳定性,等电点附近可能有利于SBP与WPH的结合,故酸性复合乳液整体表现优于中性乳液。展开更多
