目的评价实时彩色多普勒血流(CDF)超声内镜(EUS)对肿瘤及非肿瘤性胆囊息肉的鉴别诊断价值。方法这项前瞻性研究自2014年8月—2016年12月连续纳入共233例胆囊息肉病人,均接受实时CDF-EUS检查。CDF成像对每例病人进行主观分类:强CDF模式、弱CDF模式和无CDF模式。结果这233例病人中115例接受了手术切除,其中90例非肿瘤性胆囊息肉,23例肿瘤性胆囊息肉。多变量分析显示,强CDF模式是肿瘤性息肉最重要的预测因素;敏感度、特异度、阳性预测值、阴性预测值和准确度分别为52.2%、79.4%、38.7%、86.9%和73.9%。孤立性息肉和息肉大小与肿瘤风险增加有关。结论 EUS显示强CDF模式、孤立以及较大的息肉可以用来预测肿瘤性胆囊息肉。由于实时CDF-EUS安全无创,无需额外设备,因此很可能成为鉴别诊断胆囊息肉的补充检查。

Wastewater electrolysis cells (WECs) for decentralized wastewater treatment/reuse coupled with h-2 production can reduce the carbon footprint associated with transportation of water, waste, and energy carrier. This study reports Ir-doped NiFe2O4 (NFI, similar to 5 at% Ir) spinel layer with TiO2 overlayer (NFI/TiO2), as a scalable heterojunction anode for direct electrolysis of wastewater with circumneutral ph in a single-compartment cell. In dilute (0.1 M) NaCl solutions, the NFI/TiO2 marks superior activity and selectivity for chlorine evolution reaction, outperforming the benchmark IrO2. Robust operation in near-neutral ph was confirmed. Electroanalyses including operando X-ray absorption spectroscopy unveiled crucial roles of TiO2 which serves both as the primary site for Cl- chemisorption and a protective layer for NFI as an ohmic contact. Galvanostatic electrolysis of Nh4+-laden synthetic wastewater demonstrated that NFI/TiO2 not only achieves quasi-stoichiometric Nh4+-to-N-2 conversion, but also enhances h-2 generation efficiency with minimal competing reactions such as reduction of dissolved oxygen and reactive chlorine. The scaled-up WEC with NFI/TiO2 was demonstrated for electrolysis of toilet wastewater.

A pot experiment was conducted in a plastic film house to evaluate the translocation and uptake of heavy metals(Pb,Cd,Cu,and Zn) into brown rice(Oryza sativa L.) and the heavy metals residues in soils which had previously been irrigated with domestic wastewater for a long time(3 years).The range of Pb,Cd,Cu,and Zn was 5.10 ± 0.01,0.105 ± 0.017,5.76 ± 0.42,and 23.56 ± 1.40 mg kg-1,respectively in the domestic wastewater-irrigated soil,and 0.370 ± 0.006,0.011 ± 0.001,0.340 ± 0.04,and 2.05 ± 0.18 mg kg-1,respectively,in the domestic wastewater-irrigated brown *** results indicated that application of domestic wastewater to arable land slightly increased the levels of Pb,Cd,Cu,and Zn in soil and brown rice(P he concentrations of heavy metals in brown rice were lower than the recommended tolerable levels proposed by the joint FAO/WhO Expert Committee on Food ***,the continuous monitoring and pollution control of hazardous materials from domestic wastewater are needed in order to prevent excessive build-up of heavy metals in the food chain.

We focused on the surface reinforcement of ligth weight casting alloys with Ni-AI intermetallic compounds by in-situ combustion reaction to improve the surface properties of non-ferrous casting *** our previous works,green compact of elemental Ni and Al powders were reacted to form Ni-3Al intermetallic compound by ShS （Self-propagating high temperature synthesis） reaction with the heat of molten Al alloy and simultaneously bonded with Al casting *** some defects such as tiny cracks and porosities were remained in the reacted *** we applied pressure to prevent thermal cracks and fill up the pores with liquid Al alloy by squeeze casting *** compressed Al alloy bonded with the Ni-3Al intermetallic compound was sectioned and observed by optical microscopy and scanning electron microscopy （SEM）.The stoichiometric compositions of the intermetallics formed around the bonded interface and in the reacted compact were identified by energy dispersive spectroscopy （EDS） and electron probe micro analysis （EPMA）. Si rich layer was formed on the Al alloy side near the bonded interface by the sequential solidification of Al *** porosities observed in the reacted Ni-3Al compact were filled up with the liquid AI *** Si particles from the molten Al alloy were detected in the pores of reacted Ni-3Al intermetallic *** Al casting alloy and Ni-3Al intermetallic compound were joined very soundly by applying pressure to the liquid Al alloy.

α-Fe(NiCoAl) solid-solution nanocapsules were prepared with pure powders of Fe, Ni, Co and Al by the plasma arc-discharging using a copper crucible. The shapes of the nanocapsules are in polyhedrons with the core/shell structure. The body centered cubic (BCC) phase is formed in the core. The size of the nanocapsules is in the range of 10-120 nm and the thickness of the shell is 4-11 nm. Saturation magnetization jS=150 Am2/kg and coercivity ihC=24.3 kA/m are achieved for the nanocapsules.

In this work, the damage and penetration behavior of aluminum foam at various types of impact were examined through experiments. The impact energy of a striker was applied on the fixed aluminum foam having a thickness of 25 mm while increasing its impact by 2 j at each strike from 6 j to 16 j. The results show that the impact energies from 6 j to 12 j could not penetrate aluminum foam. however, the aluminum foam applied with the impact energy of 12 j incurred severe damages on its lower part. Finally, the aluminum foam applied with the impact energy of 14 j was penetrated. The striker having the impact energy of 6 j could penetrate aluminum foam around 10 mm. At this moment, aluminum foam could absorb the impact energy of around 9 j. When the impact energy of 14 j was applied on the aluminum foam, the aluminum foam was penetrated and it absorbed the impact energy of around 17.2 j. It is possible to create the safer structure against impact using the results of this work. The simulation results for the verification of the experimental results imply that the results for all the experiments in this work are reliable. It is possible to predict the structural safety of the aluminum foam for an impact if the impact behavior of aluminum foam performed in this work is utilized.

This paper presents an analysis of the coupled vibration of asymmetric core structures in tall buildings. The governing equation of free vibration and its corresponding eigenvalue problem, which is a set of equations for laterally flexural vibrations in two different directions coupled by a warping-St. Venant torsional vibration, are derived. Based on the Calerkin method, a generalized approximate method is developed for the analysis of coupled vibration and thus proposed for determining the natural frequencies and mode shapes of the structure in triply-coupled vibration. The results of the proposed method for the example structure show good agreement with those of the FEM analysis. The proposed method has been shown to provide a simple and rapid, yet accurate, means for coupled vibration analysis of core structures.
