In this study, a series of adipic acid-polyoxypropylene diamine copolymer (AA-PPA) was prepared by copolymerizing polyoxypropylene diamine (PPA D400) and adipic acid (AA). The AA-PPA with weight-average molecular weight (Mw) = 10400 and weight-average molecular weight (Mn) = 7600 was used to modify diglycidyl ether of bisphenol A (DGEBA) epoxy/diethyl toluene diamine (DDM) system. This extended polyether...
To deal with the bottle-neck of enterprise distributed multi-source heterogeneous geographic spatial data's interoperating, the four-tier integration framework of multi-source heterogeneous spatial information based on web services is designed. Through the integration of web services technology, the geographical information service criterion of OGC and the scalable vector graphics model (SVG) of W3C,...
The atmospheric weaken revised formula is obtained by simplifying split window algorithm. Land surface brightness temperature of the six monitoring regions of China is researched by using FY 2C geostationary satellite IR data (211 images from September 18, 2007 to August 15, 1008) with the above formula, the result shows that the impact of atmosphere to thermal infrared transmission is from -12K to...
The role of lamotrigine (LTG) in childhood epilepsy is emerging. We evaluated the efficacy and adverse effects of LTG in an open, prospective study of 56 children with generalized epilepsies. Six (11%) children became seizure-free, and 24 (43%) had greater than 50% reduction in seizure frequency. LTG was effective against a broad range of generalized seizure types. Three of 15 patients with Lennox-Gastaut...
