Starch viscosity is closely associated with noodle quality. RVA(rapid viscosity analyzer) was used to investigate the paste property of leading chinese wheat varieties arid 38 Australian wheat lines. Results showed that significant variability for RVA parameters was observed among chinese wheat varieties, particularly among spring wheat varieties. In {2., Australia wheat lines performed better paste characters than that of chinese winter wheats. Genotype (G), environment (E) and genotype by environment (G×E) interaction affected all paste traits. Correlation analysis indicated that peak viscosity correlated highly and significantly with viscosity, breakdown, setback, final viscosity, peak time, and falling number(r = 0.56-0.93, P<0.01). However breakdown was not significantly associated with most paste properties. Paste characters increased from low to high latitude both in the north and south part of Yellow and Huai Valley.

The amphoteric properties of four sulfide minerals were characterized byacidimetric-alkalimetric titration. Chalcocite, galena, and sphalerite were found to bediprotic acids, while pyrite was determined to be a triprotic acid. Intrinsic acidity con-stants for the four minerals are as follows: chalcocite-pK_(a1)=5.2., pK_(a2.=9.68;galena- pK_(a1)=5.2., pK_(a2.=9.62. sphalente- pK_(a1)= 5.08, pK_(a2.= 9.13;and pyrite - pK_(a1) = 3.50,pK_(a2.=5.32. pK_(a3)=9.81.

In this study, we used the Navy' s Master Oceanographic Observation Data Set(MOODS), consisting of 116019 temperature and 9617 salinity profiles, during 1968-1984 to investigate the temporal and spatial variabilities of South china Sea thermohaline structures and circulation. For temperature, profiles were binned into 2.4 monthly data sets from 1968 to 1984 (17 years). For salinity, profiles were binned into 12.climatological monthly data sets due to the data paucity. A two-scale optimal interpolation method was used to establish a three-dimensional monthly-varying gridded data set from MOODS, covering the area of 5°-2.°N and 105° - 12.°E and the depth from the surface to 400 m. After the gridded data set had been established, both composite analysis and the Empirical Orthogonal Function (EOF) analysis (for temperature only) were used to identify the major thermohaline fratures including annual mean, monthly anomalies, and interannual thermal variabilities. The inverted monthly circulation pattern using the P - vector method is also discussed.

Efron (1997) considered several approximations of p-values for simultaneous hypothesis testing. An extension of his approaches is considered here to approximate various probabilities of correlated events. Compared with multiple-integrations, our proposed method, the parallelogram formulas, based on a one-dimensional integral, not only substantially reduces the computational complexity but also maintains good accuracy. Applications of the proposed method to genetic association studies and group sequential analysis are investigated in detail. Numerical results including real data analysis and simulation studies demonstrate that the proposed method performs well.

The cloud microphysical and rainfall responses to zonal perturbations of sea surface temperature (SST) are investigated by analyzing the equilibrium simulation data (from day 31-40) obtained from a series of two-dimensional cloud-resolving simulations with a zonal model domain of 768 km. Four experiments imposed by zonal SST perturbations of wavenumbers 1 (SST2.Z1), 2.(SST2.Z2., 4 (SST2.Z4), and 8 (SST2.Z8) are compared to the control experiment imposed by zonally uniform SST (SST2.). The model domain mean SST is 2. °C, and the two-dimensional cloud-resolving model with a cyclic lateral boundary is also imposed by zero vertical velocity and constant zonal wind. The time and model domain mean surface rain rates in SST2.Z1, SST2.Z2. and SST2.Z8 are about 10% larger than those in SST2., whereas the mean surface rain rates in SST2.Z4 and SST2. are similar. The analysis of mean surface rainfall budgets shows that local water vapor and hydrometeor changes play important roles in determining the differences and similarities in mean surface rain rate between the perturbation experiments and the control experiment. Both convective and stratiform rain rates are larger in SST2.Z1 and SST2.Z2.than in SST2. due to the smaller advection of rain from convective regions into raining stratiform regions and the larger vapor condensation rates associated with the larger water vapor convergence over raining stratiform regions in SST2.Z1 and SST2.Z2. The convective rain rates are larger in SST2.Z4 and SST2.Z8 than in SST2. because of the larger condensation rates associated with the larger water vapor convergence over convective regions in SST2.Z4 and SST2.Z8. The stratiform rain rates in SST2.Z4 and SST2.Z8 are smaller than in SST2. due to the smaller vapor condensation rates and smaller collection rates of cloud water by rain over raining stratiform regions in SST2.Z4 and SST2.Z8.
