| 1 | Transition from wavelets to ripples in a laboratory flume with a diverging channel显示文摘An experimental investigation on the initiation and development of bed forms on a bed of fine silica sand was conducted under alluvial flow conditions in a laboratory flume with a diverging channel. The main aims of the study were to assess: i) the steepness of bed forms in the transition stage of development; and ii) the threshold height of wavelets (ηt) that triggered the start of ripple development. Detailed bed profile measurements were carried out using an acoustic Doppler probe, traversed longitudinally over the sediment bed at various experimentation times. The bed form dimensions were extracted from such bed profile records and analysed for the wavelet, transition and equilibrium stages. It was found that the steepness of ripples in the transition and equilibrium stages were similar, confirming predictions of previous mathematical model simulations. A lognormal distribution fitted the wavelet length data. The wavelet threshold height was estimated as ηt≈ 7 mm, or y+ ≈ 80 in wall units. Such a height magnitude suggested that ripple development could be triggered by the wavelets reaching the outer flow zone of a turbulent boundary layer. The ηt value obtained corresponded generally to the intersection point between two predictive equations for bed form dimensions. A formulation was developed to predict ηt as a function of the sediment grain size, which was confirmed for the fine sand used in this study. | William B. RAUEN Binliang LIN Roger A.

| 2 | The Severn Barrage and other tidal energy options:Hydrodynamic and power output modelling显示文摘Details are given herein of the current main proposals for tidal energy provision from the Severn Estuary, in the UK, with particular emphasis being focused on the Severn Barrage project, as originally promoted by the Severn Tidal Power Group. In particular, emphasis has focused on assessing the potential hydro-environmental impacts and power outputs of a barrage across the estuary, with an unstructured grid, high resolution, model being developed and applied to the estuary to assess the implications of each of five shortlisted proposed schemes on the hydrodynamic, geomorphologic, flood risk and faecal indicator organism changes within the estuary. An outline is given of recent research on power refinements to the model to assess the options for power generation. The results show that the Severn Barrage has the potential to reduce the tidal currents in a highly dynamic estuary. This leads to the reduction of suspended sediment loads (particularly upstream of the barrage), an increase of light penetration within the water column and, potentially, an increase in the benthic bio-diversity and the level of aquatic life in the estuary. The results also show that the Severn Barrage will reduce markedly the risk of flooding upstream of the barrage and to a lesser extent downstream of the structure. In contrast the alternative options have far less impact on flood risk changes. In addition to the Severn Barrage some results are shown herein for a typical lagoon option, namely the Fleming Lagoon. | Roger A.

| 5 | 谷氨酰胺增强结肠直肠切除病人的T淋巴细胞反应显示文摘研究目的:作者测定了在行直结肠切除的患者中,谷氨酰胺强化的肠外营养支持对手术后外周血T细胞反应及炎症细胞因子生成的影响。 背景资料:包括免疫系统在内的几种有机体组织的正常功能依赖于谷氨酰胺;然而这种氨基酸,虽然可能为应激状态所必需,近年才正式将它用于肠外营养液中。这种强化的肠外营养液对处于应激状态的外科病人的免疫功能的影响尚不清楚。 研究方法:患者(n=20)随机分为两组,在术后1~6天,一组接受传统的肠外营养液治疗(每天0.2克氮/kg),另一组每天接受含有0.188/kg谷氨酰胺的等氮等热卡方案治疗。分别在术前和术后第1~6天,体外测定:T细胞DNA合成、IL-2的生成情况以及外周血单核细胞IL-6和肿瘤坏死因子(TNF)的生成情况。 研究结果:行肠外营养治疗5天后,与术前相比,T细胞DNA的合成在谷氨酰胺强化组病人中增加了(术前~3H标记的胸腺嘧啶的平均摄取为78.3×103cpm;第6天为95.0×103cpm,P<0.05),而在对照的治疗组患者中,T细胞DNA合成没有增加(术前为89.0×103cmp,第6天为69.4×10~3cpm,P<0.05)。添加谷氨酰胺并不影响IL-2,TNF和IL-6的生成水平。 结论:添加谷氨酰胺可能是增强接受肠外营养治疗的外科病人的T细胞功能的一种方法。 | O'Riordain MG Fearon KCH Ross JA Rogers P Falconer JS Bartolo DCC Garden OJ Carter DC 赵志全 | 1996 | 中华临床营养杂志1996,14,1: | 1 |

| 15 | Physical and numerical modelling of the Severn Barrage显示文摘The Severn Estuary has one of the largest tidal ranges in the world and has long been the subject of consideration for tidal energy generation.Whilst plans to build a tidal barrage across the estuary have existed in various forms since the 1920s,the 1989Severn Tidal Power Group(STPG)proposal is commonly referred to as the original Severn Barrage.The UK government abandoned this ebb generation scheme as a public investment project in 2010.However,plans to build a two-way generation scheme were more recently put forward by a private consortium,namely Hafren Power.To assess the impact that a barrage would have on the hydro-environment in the estuary a number of numerical modelling studies have previously been conducted for the STPG scheme.As this design has now been superseded by the Hafren Power proposal,new studies have been conducted to investigate the impact of a two-way scheme.In this study the hydro-environmental impacts of both ebb-only and two-way schemes were assessed using physical and numerical modelling techniques.Scale model barrages were constructed and testing was carried out using a physical model of the Severn Estuary,located in the hydraulics laboratory at Cardiff University.A depth integrated numerical model,namely DIVAST,was applied to the physical model geometry and modifications were made to simulate the effects of the barrage structures.The numerical model predictions showed good agreement with the corresponding laboratory data.The results were consistent with conclusions from previous studies,relating to the ebb-only scheme.These included an increase in the minimum water levels upstream of the barrage,a reduction in the mean water levels downstream of the barrage and a general reduction in tidal velocities.For a two-way scheme changes in the tidal elevations and velocities depended on the exact operating conditions of the barrage.It was found that with no starting head the tidal regime was similar to the natural state,with little change in the elevations and a slight reduction in the mean velocities.As a starting head was introduced there was still little change in elevations downstream of the barrage,however,there was an increase in the minimum water levels upstream of the barrage,and a further reduction in the mean velocities. | JAMES Brammer ROGER A Falconer CHRISTOPHER Ellis REZA Ahmadian | 2014 | Science China(Technological Sciences)2014,57,8: | 0 |
