The working fluid comprised a combination of water and ethylene glycol, with volumetric proportions of (50:50) considered. Convective boundary constraints and modified Fourier law are implemented in heat transmission assessment. The mathematical flow model is formulated in the form of PDEs and is transformed into ODEs via similarity transformation. Numerical outcomes will be obtained with the use of the bvp4c technique and will be displayed with the help of graphs and tables. The results show that the surface drag coefficient is enhanced in the case of aggregation of nanoparticles whereas heat transfer rate is enhanced in the non-aggregation effect of nanoparticles. Furthermore, the temperature distribution enhances the increasing values of particle volume fraction in the case of aggregation effects of nanoparticles whereas temperature distribution lowers in the case of non-aggregation effect of nanoparticles. .展开更多
目的:探究果酸换肤联合外用主含马齿苋提取物和青刺果油护肤品治疗轻、中度寻常痤疮的临床疗效。方法:将轻、中度寻常痤疮患者随机分为对照组(果酸换肤治疗)、观察组(果酸换肤治疗联合外用主含马齿苋提取物和青刺果油护肤品),每组60例...目的:探究果酸换肤联合外用主含马齿苋提取物和青刺果油护肤品治疗轻、中度寻常痤疮的临床疗效。方法:将轻、中度寻常痤疮患者随机分为对照组(果酸换肤治疗)、观察组(果酸换肤治疗联合外用主含马齿苋提取物和青刺果油护肤品),每组60例。比较两组患者临床疗效、角质层含水量和经表皮水分流失量(Transepidermal water loss,TEWL)。结果:治疗12周后,观察组总有效率为93.33%高于对照组总有效率78.33%(P<0.05)。治疗6周、12周后观察组患者的角质含水量均高于对照组(P<0.05),且与治疗前相比,治疗6周、12周后,观察组患者的角质含水量均升高(P<0.05)。治疗6周、12周后,观察组患者的TEWL均低于对照组(P<0.05);与治疗前相比,观察组在治疗6周、12周后TEWL均降低(P<0.05)。结论:果酸换肤联合主含马齿苋提取物和青刺果油护肤品治疗面部轻、中度寻常痤疮疗效显著,同时可增加皮肤含水量,降低经表皮水分流失量,使用安全感良好。展开更多
