    Description: The characteristics of a global set-up of the Finite-Element Sea-Ice Ocean Model under forcing of the period 1958-2004 are presented. The model set-up is designed to study the variability in the deep-water mass formation areas and was therefore regionally better resolved in the deep-water formation areas in the Labrador Sea, Greenland Sea, Weddell Sea and Ross Sea. The sea-ice model reproduces realistic sea-ice distributions and variabilities in the sea-ice extent of both hemispheres as well as sea-ice transport that compares well with observational data. Based on a comparison between model and ocean weather ship data in the North Atlantic, we observe that the vertical structure is well captured in areas with a high resolution. In our model set-up, we are able to simulate decadal ocean variability including several salinity anomaly events and corresponding fingerprint in the vertical hydrography. The ocean state of the model set-up features pronounced variability in the Atlantic Meridional Overturning Circulation as well as the associated mixed layer depth pattern in the North Atlantic deep-water formation areas.

    Notes: Based on the principle of moiré techniques, a new method combined with ElectricAddressing SLM technique was proposed. The specimen grating is modulated by the SLM system,and its the frequency can be changed with aid of a 4f Fourier system. The moiré is generated by theoverlapped specimen grating and a reference grating in the Fourier system. Typical test is conductedwith a polyurethane beam. The successful results verify the feasibility of the method, and show itsgood potential of further application to the in-plane deformation measurement

    Notes: The primary aim pursued by the preparation of the separation membrane is to make themembrane thinner as well as have no defects. The field-flow fractionation deposition is a newmolding technology which can overcome the traditional disadvantages, such as multi-preparation, tothe preparation of a great area of the separation membrane with no defects. Therefore the mainingredients which influence the appearance and performance of titanium membrane layers areinvestigated by a scanning electricity mirror (SEM) as well as a porous material testing instrument:powder performance prepared and confected; selection of supporting body; sintering system such astemperature and time. It is shown that the membrane thickness can be controlled at 50μm or so

    Notes: Warm compression tests of AZ31 Mg alloy were carried out at five temperatures in30°C intervals from 210°C to 330°C. The samples of different thickness which were machinedfrom as-cast and pre-strained AZ31 billets were compressed into thickness 1mm and then cooled inthe air to room temperature. The microstructural evolution of AZ31 Mg alloy was investigatedduring warm compression forming. The results show that all the samples have undergone amicrostructure changes to different scales in the range investigated. The twinning is thepredominant deformation mechanism for magnesium alloys at moderate temperatures and itsoccurrence is dependent on temperature and strain. Microstructural evaluation indicates that themean size of the recrystallised grains decreases with increasing effective strain and temperaturebecause of sufficient dynamic recrystallization. The original grain has significant influence onmicrostructural evolution during warm forming

    Effects of High Gradient Magnetic Fields on Solidified Structures of Non-Magnetic Metals with Different Susceptibilities (2007)
    s.l. ; Stafa-Zurich, Switzerland

    Notes: In the present study, the influencing factors such as the intensity and the direction ofgradient magnetic fields, the magnetic susceptibilities of non-magnetic metals on the structures arestudied theoretically and experimentally. In the theoretical analyses, the influences of high gradientmagnetic fields on nucleation and structures are investigated. In the experimental research, highgradient magnetic fields are imposed on paramagnetic material Al and diamagnetic one Sn duringtheir solidification processes. Then the macro- and microstructures of these samples are examinedand the influences of magnetic susceptibilities of metals, the intensity and the direction of highmagnetic fields are analyzed in details. It is found that solidified structures could be refined when themagnetization force and gravity were in the same directions, while the solidified structures could becoarsened and the coarse dendrites grew along the direction of the imposed magnetic fields when thedirections of these two forces were opposite. Those phenomena could be explained from the views ofreduced gravity and elevated gravity effects caused by magnetization force and the convectionsuppression effect caused by high magnetic fields. The results indicate that high magnetic fields canbe applied to control the solidified structures of metals and then improve the quality and theproperties of materials for different purposes

    Notes: The distribution and solidified structure of alloying elements are important for thequality and the properties of alloys. In the present study, the solidification behavior ofaluminum-rich alloys is studied under various high magnetic field conditions, and theinfluences of uniform and gradient magnetic fields with different intensity and direction on thedistribution and the morphology of solute elements of Al-Cu and Al-Mg alloys are investigated.It is found that because of the differences of the electromagnetic force (Lorentz andmagnetization forces) acting on Cu element and Mg element with different physical propertiesin the matrix, the regularities of distribution for Cu element and Mg element are opposite just inthe intracrystalline and intergranular under high uniform magnetic field condition, and not onlythe content but the distributions of Cu and Mg elements are obviously different under highgradient magnetic field conditions as well. It can be concluded that high magnetic field hasdifferent effect on the solute distribution in alloys with different physical properties such asdensity, susceptibility, conductivity, etc. And the experimental results indicate that it is possibleto control the terminal solubility and morphology of the solute elements in alloys by highmagnetic fields

    Notes: Simple methods for the preparation of polymerase chain reaction (PCR) templates from Escherichia coli, Saccharomyces cerevisiae and Oryza sativa using a microwave and by boiling are described without the need for any special chemical reagent such as a detergent. The microwave and boiling methods were robust for the preparation of both plasmid and genomic templates of E. coli, as was the boiling approach for S. cerevisiae DNA. The microwave procedure was only suitable for dry yeast colonies with fair efficiency as absence of water (H2O) was critical for a successful PCR. Oryza sativa genomic DNA was amplified with both approaches with satisfactory efficiency. Escherichia coli plasmids can be prepared using a microwave with a yield equivalent to 15–20% of an alkaline lysis mini-prep. PCR templates were also efficiently generated from Pichia pastoris and Ganoderma lucidum by using the boiling method.

    Notes: Aimed at characteristics of the profile such as complex shape, high dimensional accuracy and mechanical properties, the reduction zone length and devided flow taper of female die were designed by FEM and extrusion experiments were carried out for as-cast AZ31 magnesium alloy. Technological parameters were determined and microstructure and properties of the extruded profile were examined. The results show that magnesium alloy profile can be extruded if technological parameters such as deformation temperature, tool temperature and ratio of extrusionare controlled strictly. Each of the above mentioned technological parameters has its different influence on microstructure and properties of extruded profile. In comparison with as-cast alloys, microstructure is refined from 120～140μm to about 10μm and tensile strength is enhanced from 171～200MPa to above 260Mpa. This suggests that fine grain and high strength are attained for AZ31 magnesium alloy by extrusion deformation. The extruded profile can meet high properties demands for carrying parts. It provides a possibility for broader usage of magnesium alloy profiles

    Notes: In order to study the warm forming strengthening behaviours of AZ31 magnesium alloy, plane strain compression tests were carried out at the temperatures ranged from 210 to 330℃ for as-cast and pre-forged Alloys. Tensile specimens were machined from the compressed samples. Room temperature mechanical testing was conducted according to the specifications. Microstrutres were investigated using scanning electron microscope. The analysis revealed that there is an excellent warm forming strengthening effect for as-cast AZ31 alloy with hexagonal close-packed structure. The increments of the tensible strength is about 40～50%. With decreasing temperature, the tensible strength increases during warm forming. The deformation extent and deformation mode has its different influence on strengthening effect. The high strength was attributed to the fine-grain strengthening and work hardening. This suggests that fine grain and high strength are attained for AZ31 alloy by means of rational combined action of work hardening and fine-grain strengthening during warm forming
