OPTImAL mODE OF SEDImENT TRANSPORT BY SHALLOW FLOWS IN UPLAND AREAS

引用

International Journal of Sediment Research 2000年第2期 260-267页

作者： D. PAL S. N. PRASAD (Department of Civil Engineering, University of mississippi, University, mS 38677, USA.) m. J. m. ROmKENS(USDA ARS National Sedimentation Laboratory, Oxford, mS 38655, USA.)

Soil erosion and sediment movement are serious problems of upland areas of a watershed. In these areas,most of the eroded sediment is transported in overland flows; either in shallow or in concentrated flowsituations. These flows are usually associated with nonlinear waves, generally known as "roll waves" inthe hydraulic engineering literature. Under suitable hydraulic conditions, these waves contain a significantfraction of the total kinetic energy of the flow regime. Hence, the waves act as the prim.ry energy sourcein transporting eroded sediment in shallow flows on steep slopes. Our laborat0ry experiments undercontrolled condition suggest that modulation of the roll waves is effected by the addition of increasingamouflts of sediment in the flow. The optimal condition in the sediment transport rate is reached whenmost of the available wave energy is consumed in carrying the sediment. A related set of experiments ongravitational flows of dry granular material show that the evolving scales of sediment waves are intrinsicto the transport mechanism of the solid phase.

The cerebellum expresses one of the highest levels of the plasma membrane Ca2+ATPase,isoform 2 in the mammalian *** highly efficient plasma membrane calcium transporter protein is enriched within the main output neurons of the cerebellar cortex;i.e. the Purkinje neurons(PNs) .Here we review recent evidence,including electrophysiological and calcium imaging approaches using the plasma membrane calcium ATPase 2(PmCA2) knockout mouse,to show that PmCA2 is critical for the physiological control of calcium at cerebellar synapses and cerebellar dependent *** studies have also revealed that deletionof PmCA2 throughout cerebellar development in the PmCA2 knockout mouse leads to permanent signalling and morphological alterations in the PN dendrites. Whilst these findings highlight the importance of PmCA2 during cerebellar synapse function and development,they also reveal some limitations in the use of the PmCA2 knockout mouse and the need for additional experimental approaches including cell-specific and reversible manipulation of PmCAs.

The Spatial Distribution of Nitrite Concentrations in a Large Drinking Water Distribution System in Finland

Journal of Water Resource and Protection 2017年第8期9卷 1026-1042页

Nitrite in drinking water is a potential health hazard and monitoring its concentrations in distributed water is of paramount importance. When monochloramine is used in secondary disinfection in drinking water distribution systems (DWDSs), nitrite is often formed by nitrification in the biofilm on the inner surface of distribution pipes. This article attempts to identify areas with a risk of increased nitrite concentrations as well as the main reasons leading to nitrite occurrence in a large urban DWDS in Finland using spatial inspection of obligatory monitoring data. Nitrification was found to occur throughout the study area, though nitrite was not increased everywhere. Instead, nitrite was increased close to the water treatment plants (WTPs) and was connected to fresh drinking water than stagnant drinking water. Temperature effects on nitrite concentrations were surprisingly insignificant, even though it is well known that nitrification reactions are affected by temperature. The temperature dependence of ammonium and total residual chlorine was more significant than the dependence of nitrite. The findings of this study emphasize the need to monitor nitrite concentrations close to WTPs.

A process to convert models made by rapid prototypi ng techniques like SL (stereolitography) and LOm (laminated object manufacturing) or by conventional techniques (silicones, resins, wax, etc.) into metallic mould s or tools has been developed. The main purpose of this technique is to rapidly obtain the first prototypes of parts, for plastics injection, forging or any oth er manufacturing process using the tools produced by casting a metal into a cera mic mould. Briefly, it can be said that the ceramic moulds are produced by mixing in variab le proportions, depending on the type of ceramics employed, strength and roughne ss desired, a ceramic mixture composed by alumina and/or zirconium silicates bon ded with silica coming from a liquid binder, based on ethyl silicate. A catalyst is added to the slurry in order to produce a sol-gel reaction. The liquid slur ry is poured into the box containing the mould to be reproduced. After a short p eriod of time, controlled by the amount of gelling agent, the ceramic mixture ac quires a rubber consistency. The pattern is removed from the ceramic mould, whic h is fired to stop the gelation reaction. After this stabilization the ceramic m ould is sintered at high temperatures in order to generate an inert mould wi th the desired strength in which almost all metallic alloys can be cast. The effect of ceramic materials (shape, granulometric distribution, chemical com position, etc.), processing parameters (proportion binder/ceramic/catalyst, sint ering conditions, etc.) and casting conditions (mould pre-heating temperature a nd pouring temperature) were studied in order to obtain metallic moulds or tools with tailored properties (high dimensional accuracy, low roughness and high mec hanical strength).

世界核心医学期刊文摘（胃肠病学分册） 2005年第7期1卷 36-37页

Asymmetric (ADmA) and symmetric dimethylarginine (SDmA) inhibit production of nitric oxide. The concentration of both dimethylarginines is regulated by urina ry excretion, although ADmA, but not SDmA, is also subject to degradation by dim ethylarginine dimethylaminohydrolase, which is highly expressed in the liver but also present in the kidney. The exact roles of the human liver and kidney in th e metabolism of dimethylarginines are currently unknown. Therefore, we aimed to investigate renal and hepatic handling of ADmA and SDmA in detail in 24 patients undergoing hepatic surgery. To calculate net organ fluxes and fractional extrac tion (FE) rates, blood was collected from an arterial line, the portal vein, hep atic vein, and renal vein, and blood flow of the hepatic artery, portal vein, an d renal vein was determined using Doppler ultrasound techniques. Results showed a significant net uptake (median [IQR]) of ADmA in both the liver (9.6 nmol/min [5.6- 13.2] ) and the kidney (12.1 nmol/min [1.3- 17.1]). SDmA uptake was pres ent not only in the kidney (12.7 nmol/min [3.5- 25.4]), but also in the liver ( 7.7 nmol/min [2.8- 16.4]). FE rates of ADmA for the liver and kidney were 5.0% (3.5% - 7.4% ) and 8.4% (1.3% - 13.9% ), respectively. For SDmA, hepat ic and renal FE rates were 3.4% (2.1% - 7.5% ) and 12.5% (3.6% - 16.2% ), respectively. In conclusion, this study gives a detailed description of the hepatic and renal elimination of dimethylarginines and shows that the clearing o f SDmA is not only confined to the kidney, but the human liver also takes up sub stantial amounts of SDmA from the portal and systemic circulation.

This paper studies the properties of solutions of quasilinear equations involving the p-laplacian type operator in general Carnot-Carath6odory spaces. The authors show some com-parison results for solutions of the relevant differential inequalities and use them to get some symmetry and monotonicity properties of solutions, in bounded or unbounded domains.

弹簧圈栓塞最初被设计并经美国食品药品监督管理局批准用于治疗显微外科手术夹闭风险高的脑动脉瘤，但目前该方法越来越被认为是颅内动脉瘤的一线治疗方法。动脉瘤血管内治疗技术已有长足进步，新器材的研发使得以前因血管解剖结构复杂而无法填塞的动脉瘤也得以治疗，从而扩大了血管内治疗的适应证。而且，血管内弹簧圈栓塞已成为当前动脉瘤血管内治疗的主流方法；医学文献证明，在特定患者人群中，弹簧圈栓塞的转归优于外科手术夹闭。最近的一份美国心脏协会（AmericanHeartAssociation，AHA）科学声明指出，对于适合治疗的脑动脉瘤，不论是血管内栓塞还是显微外科手术夹闭，均为破裂动脉瘤I级推荐治疗方法和未破裂动脉瘤的11a级推荐治疗方法。在这两组患者中，治疗利大于弊。一个在血管显微神经外科、神经重症监护和介入神经外科方面有着丰富经验的多学科团队最有利于对颅内动脉瘤的处理实施最佳的技术。神经血管联合写作组此前已发表过一份联合声明，提出了有关脑血管介入治疗的培训和认证的推荐意见。
