1Parametric Study of Two-Body Floating-Point Wave Absorber显示文摘在这份报纸,我们在场深水里的一个点波浪吸收器的全面数字模拟。分析在频率和时间领域被执行。变换器与在举方向的自由的一度是一个二身体的浮点吸收器(FPA ) 。它的二部分被一个线性 mass-spring-damper 系统连接。在这研究使用的商业 ANSYS-AQWA 软件表现很好在考虑确认。速度潜力被假定不可压缩、无旋的流动获得。因此,我们在精力变换和设备效率上调查了波浪特征的效果,包括波浪高度和波浪时期,以及设备直径,草稿,几何学,和抑制系数。验证模型,我们从类似的实验把我们的数字结果与那些作比较。当考虑特定的条件时,我们的学习结果能清楚地帮助最大化变换器效率。Atena Amiri Roozbeh Panahi Soheil Radfar 2016Journal of Marine Science and Application2016,15,1:6
2SYNTHESIS AND CHARACTERIZATION OF OPTICALLY ACTIVE POLYAMIDES BASED ON 2-(1,3-ISOINDOLINEDIONE-2-YL)GLUTARIC ACID BY DIRECT POLYCONDENSATION显示文摘<正>Five new optically active polyamides(PAs) 6a-6e were prepared by direct polycondensation reaction of 2-(1,3- isoindolinedione-2-yl)-glutaric acid 4 as a new chiral diacid with various aromatic diamines 5a-5e in a medium consisting of triphenyl phosphite(TPP),calcium chloride,pyridine(Py) and N-methyl-2-pyrrolidone(NMP).The polycondensation reaction produced a series of polyamids 6a-6e in quantitative yields with inherent viscosities of 0.26-0.39 dL/g.The resulting polymers were fully characterized by means of ~1H-NMR,FT-IR spectroscopy,elemental analysis,inherent viscosity and specific rotation.Thermal properties of these polymers were investigated using thermal gravimetric analysis (TGA) and differential thermal gravimetry(DTG).Phthalimide rings as a bulky pendent group in the polymer chains disturb the interchain and intrachain interactions and make these PAs readily soluble in polar,aprotic solvents such as N,N-dimethyl acetamide(DMAc),N,N-dimethyl formamide(DMF),dimethyl sulfoxide(DMSO),N-methyl-2-pyrrolidone(NMP) and sulfuric acid.Khalil Faghihi Meisam Shabanian Atena Izadkhah 2010Chinese Journal of Polymer Science2010,28,4:3
3Seven-day quintuple regimen as a rescue therapy for Helicobacter pylori eradication显示文摘AIM: To determine the efficacy of two quintupleregimens for eradication of Helicobacter pylori(H. pylori) in patients who failed previous therapies.METHODS: This prospective, open-label, randomized controlled trial was a phase Ⅱ study conducted from April 2011 to March 2012 at the Gastrointestinal and Liver Diseases Research Center in Rasht, Iran. A total of 208 patients with dyspepsia who failed previous H. pylori eradication with a ten-day quadruple therapy were enrolled. A random block method was used to assign patients to one of two treatment groups. Patients in the first group were treated with 240 mg bismuth subcitrate, 20 mg omeprazole, 1000 mg amoxicillin, 500 mg clarithromycin and 500 mg tinidazole(BOACT group). Patients in the second group received a regimen containing 240 mg bismuth subcitrate, 20 mg omeprazole, 500 mg tetracycline, 500 mg metronidazole and 200 mg ofloxacin(BOTMO group). Both regimens were given twice daily for a duration of seven days. The eradication was confirmed by a 14 C urea breath test 12 wk after completion of therapy. Patient compliance and drug side effects were evaluated at the end of the treatment period. The success rates were calculated by intention-to-treat and per-protocol analyses.RESULTS: A total of 205 patients completed the course of treatment, with three patients excluded due to drug intolerance. The mean age of patients did not differ between the BOACT and BOTMO groups(41.6 ± 12.2 years vs 39.6 ± 11.8 years), and no significant differences were found between the two groups in terms of age, sex, smoking habits or the initial eradication regimen. The intention-to-treat and perprotocol eradication rates were significantly higher in the BOTMO group(86.5%, 95%CI: 0.85-0.87 and 86.7%, 95%CI: 0.80-0.89, respectively) compared with the BOACT group(75.5%, 95%CI: 0.73-0.76 and 76%, 95%CI: 0.69-0.80, respectively)(P < 0.05). Univariate analyses for both groups did not show any association of sex, smoking and initial therapeutic regimen witheradiation rate(P > 0.05 for all). Significantly more patients experienced side effects in the BOACT group compared to the BOTMO group(77.4% vs 36.6%, P < 0.01). This difference was exemplified by increases in headache and taste disturbance(P < 0.05).CONCLUSION: Quintuple therapy with a BOTMO regimen is an alternative second-line rescue therapy for Iranian patients with failed first-line eradication treatment of H. pylori.Fariborz Mansour-Ghanaei Farahnaz Joukar Mohammad Reza Naghipour Atena Forouhari Seyed Mohammad Seyed Saadat 2015World Journal of Gastroenterology2015,21,2:2

5非穿透性深度巩膜切除术+MMC Tenon囊下注射治疗开角型青光眼术后高阶像差变化的研究(英文)显示文摘目的:研究开角型青光眼患者非穿透性深层巩膜切除术后高阶像差的变化。方法:研究包括20例患者20眼,其中10例为原发性开角型青光眼,10例为继发性开角型青光眼。患者术前接受非穿透性深层巩膜切除术,并辅以Tenon囊下注射(0.02%of MMC)。术前及术后1、3mo用i-Trace分析仪测定角膜总高阶像差。每次随访时评估眼压(IOP)、最佳矫正视力(BCVA)和眼泡形态。手术的成功率分为完全成功、相对成功和失败。结果:术前IOP为24.05±3.07 mmHg,平均用药2.85±0.67次,随访3mo后,IOP为12.30±3.32 mmHg,平均用药0.70±0.98次。随访期间IOP均明显下降(P<0.001)。术后随访1mo,总高阶像差(HOT)均方根(RMS)和总球型像差值明显升高,3mo后下降。术后各时间段三叶肌和全眼昏迷样像差变化无统计学意义。术后1mo HOT RMS及球形角膜均明显增加,3mo随访后明显减少。术后角膜三叶肌变化与术前相比无统计学意义。患者年龄和IOP对HOT和角膜HOT的变化无显著影响。结论:深度巩膜切除术后1mo内角膜和眼部高阶像差增加,3mo后下降,与术前相比无统计学意义。在3mo随访时,患者的BCVA和等效球镜(SE)与术前相比无统计学差异。Ali Mostafaei Nazli Taheri Atena Latifi 2019国际眼科杂志2019,19,11:1
