5对于室间隔缺损合并肺动脉闭锁的患儿,与死亡、再次手术和获得完全修复相关的独立因素显示文摘OBJECTIVES:We described morphologic characteristics, particularly pulmonary an atomy, and determined the prevalence of definitive end states and their determin ants in children with pulmonary atresia associated with ventricular septal defec t(PAVSD). BACKGROUND: Pulmonary atresia associated with ventricular septal defec t represents a broad morphologic spectrum that greatly influences management and outcomes. METHODS: From 1975 to 2004, 220 children with PAVSD presented to our institution. Blinded angiographic review(n=171) characterized bronchopulmonary s egment arterial supply. RESULTS:A total of 185 patients underwent surgery,and re pair was definitive in 75%. Initial operations included systemic-pulmonary art ery shunt in 57%, complete primary repair in 31%, or right ventricular outflow tract reconstruction in 12%. Based on angiographic review,118 patients had sim ple PAVSD and 53 patients had PAVSD with major aortopulmonary collateral arterie s(MAPCAs). Overall survival from initial operation was 71%at 10 years. Risk fac tors for death after initial operation included younger age at repair, earlier b irth cohort, fewer bronchopulmonary segments supplied by native pulmonary arteri es, and initial placement of a systemic-pulmonary artery shunt. Competing risks analysis for initially palliated patients predicted that after 10 years, 68%ac hieved complete repair(with associated factors including later birth cohort and more bronchopulmonary segments supplied by native pulmonary arteries), 22%died without repair, and 10%remained alive without repair. Reoperations after comple te repair occurred in 38 children(27%), with risk factors including older age a t palliation, MAPCAs, and more segments supplied by collaterals. CONCLUSIONS: Ou tcomes in children with PAVSD have improved over time, and are better in complet ely repaired cases. Bronchopulmonary arterial supply is an important determinant of mortality, achievement of definitive repair, and post-repair reoperation.Amark K.M. Karamlou T. O'Carroll A.

6LOW TEMPERATURE ALUMINUM FLOATING ELECTROLYSIS IN HEAVY ELECTROLYTE Na_3AlF_6-AlF_3-BaC1_2-NaCl BATH SYSTEM显示文摘Multiple regression equations of liquidus temperature, electrical conductivity and bath density of the Na3AlF6-AlF3-BaC12-NaCl system were obtained from experiments by using orthogonal regression method. The experiments were carried out in 100A cell with low melting point electrolyte, the influences of cathodic current density, electrolytic temperature, density differences of bath and liquid aluminum on current efficiency (CE) were studied; when the electrolyte cryolite ratio was 2.5, w(BaC12) and w(NaCl) were 48% and 10%, respectively, CE reached 90% and specific energy consumption was 10.97k Wb/kg/kg. Because of the fact that aluminum metal obtained floated on the surface of molten electrolyte, this electrolysis method was then defined as low temperature aluminum floating electrolysis. The results showed that the new low temperature aluminum electrolysis process in the Na3AlF6-AlF3-BaC12-NaCl bath system was practical and promising.H.M. Lu and K.M.

8A discrete model for prediction of radon flux from fractured rocks显示文摘Prediction of radon flux from the fractured zone of a propagating cave mine is basically associated with uncertainty and complexity. For instance, there is restricted access to these zones for field measurements, and it is quite difficult to replicate the complex nature of both natural and induced fractures in these zones in laboratory studies. Hence, a technique for predicting radon flux from a fractured rock using a discrete fracture network(DFN) model is developed to address these difficulties. This model quantifies the contribution of fractures to the total radon flux, and estimates the fracture density from a measured radon flux considering the effects of advection, diffusion, as well as radon generation and decay. Radon generation and decay are classified as reaction processes. Therefore, the equation solved is termed as the advection-diffusion-reaction equation(ADRE). Peclet number(Pe), a conventional dimensionless parameter that indicates the ratio of mass transport by advection to diffusion, is used to classify the transport regimes. The results show that the proposed model effectively predicts radon flux from a fractured rock. An increase in fracture density for a rock sample with uniformly distributed radon generation rate can elevate radon flux significantly compared with another rock sample with an equivalent increase in radon generation rate. In addition to Pe, two other independent dimensionless parameters(derived for radon transport through fractures) significantly affect radon dimensionless flux.Findings provide insight into radon transport through fractured rocks and can be used to improve radon control measures for proactive mitigation.K.M.

16Crystallization inhibition of an amorphous sucrose system using raffinose显示文摘The shelf life of pure amorphous sucrose systems, such as cotton candy, can be very short. Previous studies have shown that amorphous sucrose systems held above the glass transition temperature will collapse and crystallize. One study, however, showed that adding a small percent of another type of sugar, such as trehalose, to sucrose can extend the shelf life of the amorphous system by slowing crystallization. This study explores the hypothesis that raffinose increases the stability of an amorphous sucrose system. Cotton candy at 5 wt% raffinose and 95 wt% sucrose was made and stored at room temperature and three different relative humidities (%RH) 11%RH, 33%RH, and 43%RH. XRD patterns, and glass transition temperatures were obtained to determine the stability as a function of %RH. The data collected showed that raffinose slows sucrose crystallization in a low moisture amorphous state above the glass transition temperature and therefore improves the stability of amorphous sucrose systems.LEINEN K.M.
