1用OxyCup~工艺生产铁水显示文摘OxyCup工艺是一种能够利用多种氧化物粉尘和粉碎的废钢生产同高炉铁水质量相当的铁水的灵活工艺。它不仅可以使用钢厂内产生的氧化物,而且还能使用铁矿粉或预还原铁粉末。在不锈钢生产中,OxyCup还可以从相应的粉尘和尘泥残渣中提炼出液态铬、镍合金。除了铁水之外,OxyCup还产出与高炉一样的炉渣和煤气,可进一步利用。铁水可用于转炉炼钢或作为电炉钢厂的废钢补充,从而提高产量。因电炉生产中,铁水可以提高熔化效率,从而降低整体能耗和减少炼钢时间。Michael Lemperle H Jaan Rachner 韩晓杰 2013世界钢铁2013,,2:5
2Submerged flexible vegetation impact on open channel flow velocity distribution: An analytical modelling study on drag and friction显示文摘In this paper,an analytical model that represents the streamwise velocity distribution for open channel flow with submerged flexible vegetation is studied.In the present vegetated flow modelling,the whole flow field has been separated into two layers vertically: a vegetated layer and a non-vegetated free-water layer.Within the vegetated layer,an analysis of the mechanisms affecting water flow through flexible vegetation has been conducted.In the non-vegetated layer,a modified log-law equation that represents the velocity profile varying with vegetation height has been investigated.Based on the studied analytical model,a sensitivity analysis has been conducted to assess the influences of the drag (CD) and friction (Cf ) coefficients on the flow velocity.The investigated ranges of CD and Cf have also been compared to published values.The findings suggest that the CD and Cf values are non-constant at different depths and vegetation densities,unlike the constant values commonly suggested in literature.This phenomenon is particularly clear for flows with flexible vegetation,which is characterised by large deflection.Jaan H.

6Development of a novel electrospun nanofibrous delivery system for poorly water-soluble β-sitosterol显示文摘Electrospinning was used as a novel technique for fabricating polymeric nanofibers of a serum cholesterol lowering and poorly water-soluble plant sterol, β-sitosterol. Chitosan was used as a stabilizer/carrier polymer. The mean diameters of nanofibers ranged from 150 nm to218 nm. β-sitosterol was in an amorphous form and homogeneously dispersed in the nanofibers. The β-sitosterol-loaded nanofibers were freely water-soluble and exhibited very short lag-time in releasing the plant sterol. The dissolution was associated with an immediate recrystallization of β-sitosterol in submicron level. In conclusion, electrospinning is a promising future technology for the formulation of poorly water-soluble plant sterols.Urve Paaver Ivo Laidmae Hélder A.Santos Jouko Yliruusi Jaan Aruvali Karin Kogermann Jyrki Heinamaki 2016Asian Journal of Pharmaceutical Sciences2016,11,4:1
