A direct solver with O（N） complexity for integral equations on one-dimensional domains

引用

Frontiers of mathematics in China 2012年第2期7卷 217-247页

作者： Adrianna GILLmAN Patrick m. YOUNG Per-Gunnar mARTINSSON Department of Applied mathematics University of Colorado at Boulder BoulderCO 80309-0526 USA

An algorithm for the direct inversion of the linear systems arising from NystrSm discretization of integral equations on one-dimensional domains is described. The method typically has O（N） complexity when applied to boundary integral equations （BIEs） in the plane with non-oscillatory kernels such as those associated with the Laplace and Stokes＇ equations. The scaling coefficient suppressed by the ＂big-O＂ notation depends logarithraically on the requested accuracy. The method can also be applied to BIEs with oscillatory kernels such as those associated with the helmholtz and time-harmonic maxwell equations; it is efficient at long and intermediate wave-lengths, but will eventually become prohibitively slow as the wave-length decreases. To achieve linear complexity, rank： deficiencies in the off-diagonal blocks of the coefficient matrix are exploited. The technique is conceptually related to the h- and h2-matrix arithmetic of hackbusch and coworkers, and is closely related to previous work on hierarchically Semi-Separable matrices.

First-line eradication of h pylori infection in Europe:A metaanalysis based on congress abstracts,1997-2004

引用

World Journal of Gastroenterology 2006年第33期12卷 5311-5319页

作者： Gyrgy m Buzás Jolán Józan Ferencváros health Center Gastroenterology Budapest Hungary National Institute of Traumatology Department of Experimental Medicine Budapest Hungary

AIm： To meta-analyse the European abstracts presented between 1997-2004 at the European hpylori Study Group, United European Gastroenterology Week meetings and World Congresses of Gastroenterology. mEThODS： The abstracts of randomized/controlled prospective studies were classified into groups based on first-line eradication schedules. The quality of the abstracts was checked by a validated score system. The pooled eradication rates （PER） and combined odds ratios （OR） were calculated and compared with the published meta-analyses. RESULTS： The PER of proton pump inhibitor-based （PPI） one week triple therapies was 81.4% （confidence interval, 95% CI： 78.5-84.5）. Ranitidine bismuth citratebased （RBC） triple regimens have an efficiency rate of 78.5% （95% CI： 70.5%-84.3%）（P = 0.28 vs PPI）. The OR for PPI effect vs RBC regimens was 1.1 （95% CI： 0.92-1.30）. h2 receptor antagonist-based triple therapies achieved 64.1% （95% CI： 52.6-75.6）（P = 0.02 〈 0.05 vs PPI）, the OR vs PPI regimens was 1.55 （95% CI： 0.72-3.78）. PPI-based double combinations were less efficient than triple regimens （PER： 55.0%, OR： 4.90, 95% CI： 2.36-9.70）. Quadruple regimens were successful in 82.6% （95% CI： 76.0-89.7）, the OR vs triple therapies was 0.80 （0.62-1.03）. Clarithromycin ＋ amoxicillin or nitroimidazole combinations were efficient in 80.5% （95% CI： 77.2-84.2） and 83.8% （95% CI： 81.7-85.9）, respectively. Amoxicillin ＋ nitromidazole therapies eradicated the infection in 73.5% （66.6-78.5）（P = 0.01 〈 0.05 vs clarithromycin-based regimens）. CONCLUSION： PPI/RBC-based triple therapies achieved comparable results with the meta-analyses. h2-receptor antagonists and PPI-based double combinations were less efficient. Triple and quadruple regimens were equally effective. Clarithmmycin ＋ either amoxicillin or nitroimidazole containing regimens were more effective than amoxicillin ＋ nitroimidazole combinations. high quality congress abstracts constitutes a valuable pool of data which is suitable for

Adsorption properties of Rosmarinus officinalis oil as green corrosion inhibitors on C38 steel in 0.5 m h_2SO_4

Acta metallurgica Sinica(English Letters) 2010年第1期23卷 13-20页

Rosmarinus officinalis essential oil obtained by hydrodistillation was tested as corrosion inhibitor of steel in 0.5 m h2SO4 using weight loss measurements, and electrochemical .polarisation methods. Results obtained indicate that the corrosion rate is reduced and R. officinalis oil adsorbs on the metal surface and then inhibits corrosion process. Its inhibition efficiency increases with oil increasing content to reach 61% at 1 g/L. Polarisation curves indicate that RO acts as a cathodic inhibitor. The inhibition efficiency of naturally oil remains slightly constant with the rise of temperature. Chemical analysis of R. officinalis essential oil was carried out using capillary GC and GC/mS. The oil composition was characterized by high amount of oxygenated monoterpene （77%） with 1,8-cineol （52.1%） as main component. Discussion of adsorption was investigated on the the isotherm adsorption of essential oil on basis of essential oil composition. Finally the steel has been also reported.

Purification of L-asparaginase II by crystallization

引用

Frontiers of Chemical Science and Engineering 2013年第1期7卷 37-42页

作者： Y. LIU m. PIETZSCh J. ULRICh Thermal Process Engineering Center for Engineering Science Martin Luther University Halle-Wittenberg D-06099 Halle (Saale) Germany Department of Downstream Processing Institute of Pharmacy Faculty of Natural Sciences I Martin Luther University Halle-Wittenberg D-06099 Halle (Saale) Germany

here a case study ofL-asparaginase II out of a recombinant Escherichia coli is presented. The target protein was obtained by simple cell disintegration and acetone precipitation. The L-asparaginase II has been crystallized in three different forms in the following microbatch crystallization. The rod-shaped crystals （-400 μm edge length） were obtained at either 8℃ or 22℃ after 17h by addition of PEG6ooo. The rectangular-shaped crystals were obtained after further recrystallization of the rod-shaped crystals. The rhombic-shaped crystals formed at 8℃ after 12 days when cold ethanol was used instead of PEG6000. All crystallizations were performed in tris-acetate buffer （50mmol-L-1, ph 5.1）. By crystallization, the specific activity of L-asparaginase II has increased 5-fold. The protein content and the purity of the crystals were evaluated by sodium dodecyl sulfate polyacrylamide gel electrophoresis （SDS-PAGE）. The more concentrated L- asparaginase II out of an extract mixture and the presence of only less minor proteins after crystallization demonstrates that crystallization is an effective and mild method to purify the target protein. The single crystal X-ray diffraction pattern reveals that the crystals are proteins and the X-ray powder diffraction （XRPD） pattern shows clearly that the crystals forming in PEG600o and ethanol have different crystal structures.

六例人胰腺移植体经UW-Belzers溶液灌注后24小时,每例均观察到内、外分泌部的毛细血管发生显著的改变,这种变化随保存期限而不同。在所采用的各种研究方法中,包括半薄切片、血管腐蚀标本、扫描电镜及透射电镜标本均观察到最初内皮肿胀常伴有血管体积缩小,其后部分内皮细胞质脱落入血管腔,毛细血管小孔数量增加,整个血管呈现退行性变化。在经复苏抢救的胰腺移植体,存在持续的前损伤,早在14小时即呈现明显的血管外渗出,36小时后程度加剧。因此,为了防止可能出现的并发症,此种移植体不宜采用。在通常情况下UW-Belzers溶液对胰腺移植体的保存期限为24小时,超出这一界限则难以充分地再血管化。
