x.E Youyu went to Antarctica in November, 1985. It was the second time that China sent a scientific ex.edition to the South Pole. On the eve of her Antarctic trip, my colleagues and I visited her. On behalf of all the staffers of Women of China, we presented her with a flag bearing the words "Bring Credit to Our Country" and asked her to plant the flag at the South Pole which ex.ressed our concern for China’s research in Antarctica, as well as our respect for x.e and her brave venture. x.e spent four months at

Nanometer powders can be produced by an electrohydrodynamic technique. The breakup mechanism of the metal droplets generated by the electrohydrodynamic technique was analysed. It showed that the applied voltage, the electric field Btrength, the properties of the molten metal and the volumetric flow rate of the molten metal directly effect the breat-up ex.ent of the metal droplets.

Teff-oat composites were developed using gluten free teff flour containing essential amino acids and minerals along with oat products containing β-glucan known for lowering blood cholesterol. Teff-oat composites were evaluated for their pasting and rheological properties by a Rapid Visco Analyzer (RVA) and an advanced rheometer. All teff-oat composites showed increased water holding and pasting viscosities with increasing oat contents compared to wheat flour. However, they were only significantly influenced by 80% oat products in teff-oat composites compared with teff flour alone. OBC (oat bran concentrate) had the highest elastic modulus G’ among the starting materials. The elastic modulus G’ for teff-Nutrim (oat bran hydrocolloid) composites were decreased with increasing Nutrim contents in composites. In contrast, the increasing content of OBC in composites significantly raised both G’ and G”. The elastic modulus G’ and viscous modulus G” for all teff-OBC composites were higher than teff and wheat flour. All WOF composites showed similar rheological properties. All composites had shear thinning properties that are important to mouthfeel and industrial applications. These teff-oat composites were developed using feasible procedures. They have improved nutritional value and tex.ure qualities for functional food applications.

Ancient grains were known for special nutritional values along with gluten free qualities. Amaranth, quinoa, teff, and buckwheat flours were evaluated for pasting properties, water holding capacities, phenolic contents, and antiox.dant activities (free and bound). They all had higher water holding capacities than wheat flour. Amaranth, quinoa, and teff showed higher pasting viscosities than wheat flour. Buckwheat flour had the highest free, bound and total phenolic contents among the flours in all aqueous ex.racts. The bound phenolic contents were higher than the free phenolic contents regardless of the solvents with the ex.eption of water ex.raction of quinoa and buckwheat. The free phenolic compounds for all four flours were highest in water ex.ract, and least in 100% ethanol. Bound antiox.dant activities were much higher than the free antiox.dant activities regardless of solvents for all products. The free antiox.dant activities from water and 50% ethanol were higher than 100% ethanol. In contrast, more bound phenolics were ex.racted with 100% ethanol than water and 50% ethanol. Our study suggested that the total phenolic contents and antiox.dant activities of grains could be underestimated in the literature without considering the bound phenolic compounds. These ancient grains have nutrition, antiox.dants, and tex.ural qualities suitable for functional foods.

A preliminary model is proposed to describe quantitatively the position and movement of cusp equatorward boundary. This integrated model, consisting of an empirical model of the magnetopause and a compressed dipolar model of Open/Closed field line, connects quantitatively the solar wind conditions, subsolar magnetopause and cusp equatorward boundary. It is shown that the increasing solar wind dynamic pressure and the increasing southward Interplanetary Magnetic Field (IMF) component drive the magnetopause to move inward and the cusp equatorward. This model is adopted to interpret quantitatively the cusp movement of August 14, 2001 observed by Cluster. The results show that the subsolar magnetopause moved earthward from 10.7 Re to 9.0Re during the period of 002300-002800 UT, and correspondingly the cusp equatorward boundary shifted equatorward. The observations of Cluster C1 and C4 show the cusp equatorward boundary that Cluster C1 and C4 were crossing during same interval moved equatorward by 4.6°. The cusp equatorward boundary velocity computed in the theoretical model (10.7 km/s) is in good agreement with the observed value(9.4km/s) calculated from the data of CIS of Cluster C4 and C1.

The LIVE （Late In-Vessel Phase Ex.eriments） test program investigates in-vessel melt pool behaviour and cooling strategies for in-vessel corium retention during severe accidents in light water reactors （LWR）. The main part of the LIVE facility is a 1：5 scaled semi-spherical lower head of a typical pressurized water reactor. Up to now, LIVE ex.eriments have been performed in different initial ex.ernal cooling conditions, melt volumes and internal heat generations. At present the well-known simulant material KNO3-NaNO3 in non-eutectic composition （80 mole% KNO3-20 mole% NaNO3） and in eutectic composition （50 mole% KNO3- 50 mole% NaNO3） is used in the live program. The 3D heat flux.distribution through vessel wall, melt pool temperature, crust thickness and the pool melt composition can be measured or determined. Ex.ensive results have been obtained concerning the melt pool thermal hydraulic behaviour in transient and in steady state conditions.
