Microb.al deposits commonly occur at the transition b.tween carb.nate and sulphate facies,and they also ab.und in the uppermost part of the middle Wuchiapingian Zechstein Limestone in west *** deposits occur as isolated reefs of the b.sinal zone and in the condensed sequences in most parts of the study *** deposits of the latter category reflect evaporative drawdown,and the ab.upt b.undary b.tween the carb.nate and sulphate deposits in the b.sin suggests the nature of evaporites that start to precipitate as soon as they reach the saturation level.A few-metre-thick unit of mostly b.ecciated microb.al deposits at the top,reefal portion of the Zechstein Limestone records extreme palaeoenvironmental events that occurred at the transition from carb.nate to sulphate *** events are related first to sub.erial exposure of the reef,which lasted several 10~5 years and then to the Lower Anhydrite transgression.

The ob.ectives of this study were to(1)simulate streamflow,total sediment(TS),total phosphorus(TP),and total nitrogen(TN)loads;and(2)use the sequential uncertainty fitting(SUFI-2)algorithm to quantify the model parameter sensitivity and uncertainty in simulating streamflow,TS,TP,and TN loads using Soil and Water Assessment(SWAT)model in b.g Sunflower River watershed(b.RW).The model was calib.ated from 1996 to 2003 and validated from 2004 to 2010 for daily streamflow,TS load,TP load,and TN *** model performed well simulating daily streamflow(R^2=0.58-0.75,NSE=0.47-0.75),TS load(R^2=0.50-0.72,NSE=0.47-0.66),and TP load(R^2=0.79-0.82,NSE=0.73-0.77),and the model performance was slightly low for TN load(R^2=0.13-0.31,NSE=0.09 to 0.07).This study determined that parameter uncertainty was greatest for simulating TN load(p-factor=0.48,r-factor=1.25)and that parameter uncertainty was lowest for simulating streamflow(p-factor=0.70-0.78,r-factor=1.18-1.19).Output uncertainty was much greater during peak streamflow and peak pollutant loads compared to periods of low streamflow and low pollutant *** sensitivity analyses found that streamflow was most sensitive to Manning’s roughness coefficient for the main channel(ch_N2),TS load was most sensitive the peak rate adjustment factor for sediment routing in the trib.tary channels(ADJ_PKR),TP load was most sensitive to the Phosphorus enrichment ratio for loading with sediments(ERORGP),and TN load was most sensitive to the denitrification exponential rate coefficient(CDN).Uncertainty was found to b. much greater during peak streamflow and peak pollutant loads compared to periods of low streamflow and low pollutant loads.

Feature sensitive simplification and re-sampling of point set surfaces is an important and challenging issue for many computer graphics and geometric modeling *** on the regular sampling of the Gaussian sphere and the surface normals mapping onto the Gaussian sphere,an adaptive re-sampling framework for point set surfaces is presented in this paper,which includes a naive sampling step b. index propagation and a novel cluster optimization step b. normalized *** proposed re-sampling scheme can generate non-uniformly distrib.ted discrete sample points for the underlying point sets in a feature sensitive *** intrinsic geometric features of the underlying point set surfaces can b. preserved efficiently due to our adaptive re-sampling scheme.A novel splat rendering technique is adopted to illustrate the efficiency of our re-sampling ***,a numerical error statistics and surface reconstruction for simplified models are also given to demonstrate the effectiveness of our algorithm in term of the simplified quality of the point set surfaces.

AIM: To assess the agreement within 3 commonly used symptom-reflux association analysis (SAA) parameters investigating gastroesophageal reflux disease (GERD) in infants. METHODS: Twenty three infants with suspected GERD were included in this study. Symptom index (SI), Symptom sensitivity index (SSI) and symptom association prob.b.lity (SAP) related to cough and irritab.lity were calculated after 24 h comb.ned pH/multiple intraluminal impedance (MII) monitoring. Through defined cutoff values, SI, SSI and SAP values are differentiated in normal and ab.ormal, whereas ab.ormal values point towards gastroesophageal reflux (GER) as the origin of symptoms. We analyzed the correlation and the concordance of the diagnostic classification of these 3 SAA ***: Evaluating the GER-irritab.lity association, SI, SSI and SAP showed non-identical classification of normal and ab.ormal cases in 39.2% of the infants. When irritab.lity was taken as a symptom, there was only a poor inter-parameter association b.tween SI and SSI, and b.tween SI and SAP (Kendall’s tau b.= 0.37, P b.= 0.36, P b.ormal cases in 52.2% of the patients. When cough was taken as a symptom, only SI and SSI showed a poor inter-parameter association (Kendall’s tau b.= 0.33, P b. taken into consideration when interpreting the results of SAA in infants.

Ga-Al-MFI samples were synthesized in hydrothermal conditions from gels of composition 1.08ch3NH2- 0.134TPAb.-1SiO2-xAl2O3-yGa2O3-40H2O at 175 ℃ for 7 days, with x = 0.005 and 0.0025, y = 0.005, 0,010 and 0.020. The samples were characterized b. XRD, b.T measurements, thermal analysis （TGA-DTA） atomic ab.orption and high resolution solid state MAS 27Al and 71Ga NMR measurements. The aromatization of propane was studied as catalytic test. The activity and selectivity of the catalysts were determined for b.nzene, toluene and xylenes on the one hand and for methane and ethane on the other hand. The most active sample was ob.ained with the highest Ga/AI ratio. For this sample, the b.X selectivity ob.ained b. aromatization was always higher than the hydrocracking selectivity leading to methane and ethane. The relative amount of toluene was higher than that of b.nzene and ofxylenes. The samples were deactivated b. coke formation that was revealed more severe for the most active sample,
