Three new metal organic frameworks (MOFs) with chemical formulae [(CH3)2NH2] [Sm3(L1)2(HCOO)2(DMF)2(H2O)]·2DMF·18H2O (1), [Cu2(L2)(H2O)2]·2.22DMA (2) and [Zn2(L1)(DMA)]·1.75DMA were synthesized and structurally characterized. 1 and 2 show a classical NbO-like topology and have two types of interconnected cages. 3 exhibits an uncommon zzz topology and has(More)
The demands for fresh process waters and heating/cooling utilities arise intermittently in batch plants. Due to equipment constraints, the quality and flow-rate of each resulting wastewater stream are required to be controlled within specified limits before treatment/regeneration. In this paper, a general mathematical programming model is developed to(More)
OBJECTIVE To investigate the effect of ischemic postconditioning on the expression of rat myocardium matris metalloproteinase-2 (MMP-2) induced by ischemia/reperfusion (I/R) and relationship between its expression and interstitium and the effect on left ventricular function. METHODS Twenty-four rats were randomly divided into 3 groups (n = 8): sham(More)
OBJECTIVE To investigate the effects of ischemic postconditioning (IPTC) on the changes of matrix metalloproteinases-2 (MMP-2) and tissue inhibitor of metalloproteinase-2 (TIMP-2) protein and mRNA levels in rat heart subjected to ischemia/reperfusion, and explore the mechanism by which IPTC protects myocardial interstitium following ischemic/reperfusion(More)
OBJECTIVE To investigate the relationship between apoptosis of myocardial cell in the rats with sepsis and the expressions of Toll-like receptor 4 (TLR4), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) mRNA, and the protective effect of glutamine (Gln) against apoptosis of myocardial cell. METHODS Rat model of sepsis was reproduced by(More)
OBJECTIVE To develop a qualitative and quantitative determination of multiple components for quality control of Hugu Capsule, a composite prescription in TCM. METHODS HPLC analysis was performed on a Kromasil C18 column (5.0 microm, 250 mm x 4.6 mm) by gradient elution with methanol-acetonitrile-1% glacial acetic acid as the mobile phase at a flow-rate of(More)
This paper1 introduces the notion of attribute-based concurrent signatures. This primitive can be considered as an interesting extension of concurrent signatures in the attribute-based setting. It allows two parties fairly exchange their signatures only if each of them has convinced the opposite party possesses certain attributes satisfying a given signing(More)
OBJECTIVE To explore the application value of correspondence analysis in ecological study. METHODS We adopted correspondence analysis method to analyze the relationship between the amount of food intake in some cities in China and the male gastric carcinoma mortality. RESULTS According to scatter plots of row and column points, there were regional(More)
