| 1 | 环境振动响应下悬索桥的系统识别显示文摘对环境振动响应下悬索桥系统识别的应用进行研究和评估。为获得桥的动力特征,采用只有两个输出时间域的系统识别方法,即与Ibrahim时域方法相结合的随机衰减法,与特征系统实现算法相结合的自然励磁技术。研究两种方法的精度和效果并与有限元方法结果进行了比较。两种方法论证的系统识别的结果表明,环境振动测量可以提供桥动态特征的可靠信息。然而,与特征系统实现算法相结合的自然励磁技术更实用和有效,尤其是应用于多波段测量庞大数据时。3天的测量结果显示,风速与自然频率和阻尼比率相关,尤其在低阶模态时。 | Dionysius M.

| 10 | 日本钢桥的历史和技术发展综述(英文)显示文摘在日本,由于钢材具有良好的抗震性能、成熟的施工和制造技术,成本竞争力以及在跨越能力方面的优势,从而广泛用于桥梁结构。钢桥约占公路桥梁总数的38.3%。本文对日本的钢桥历史和技术发展进行了综述,主要包含结构分析、材料、标准的结构设计以及检测维护等四个方面。日本钢桥的建造历史可以追溯到1868年。早期建造的桥梁没有统一的设计标准,第一部钢桥设计标准于1939年起草。该标准规定,日本的公路桥分为国道桥梁和县道桥梁两级,标准车辆荷载分别为13 t和9 t。自1950年以来,钢铁生产和焊接技术的发展取得了显著进步,并且设计和施工规范也定期更新以适应新技术的发展。日本在1960年进入了基础设施的大规模建设时期,主要是因为1964年的东京奥运会。在此期间,建造了现代斜拉桥和悬索桥,并开始进行本州四国联络桥的技术研究。此外,开始建设东海道新干线、首都高速公路、名神高速公路和东名高速公路等交通基础设施。钢桥结构相关的材料、分析、设计和施工技术得到了迅速发展和进步。2000年以后,钢桥的发展主要集中于降低建设成本、改善全寿命周期的设计、施工和维护等方面。日本钢桥研发的最初驱动力是在广阔而复杂的的地形条件下提供可靠的基础设施,以支持经济增长。在材料方面,钢桥的建设需求促进了高性能钢、高强度钢丝和高强螺栓的发展。另一个值得注意的驱动力是地震和台风等灾难造成的基础设施损失。抗震和抗风工程领域的需求推动了高质量钢材的生产以及钢桥安全性和可维修性的研究。大跨径钢桥的桥塔、主梁和索等对风敏感,因此开发了相关的风洞试验和分析技术。自1995年兵库县南部地震以来,钢桥的抗震、隔震以及抗震改造等技术一直稳步发展。在研究和开发之后,更新了设计指南,从而推进钢桥设计和建造的标准化。近些年,随着钢桥桥龄逐步增大,其维护逐步成为管理的重点。在钢桥防锈蚀方面,已经研发和应用了钢桥涂装、除湿系统等技术。随着桥龄、车流量和车辆载重的增长,钢桥的疲劳问题也逐步出现。为了解决该问题,开发了疲劳裂纹检测和维修技术等。在钢桥检测和维护领域,许多新兴的技术也得到了应用,例如基于无人机的桥梁检测、基于电磁技术的无损检测、混凝土桥面板的雷达探测等。经过数十年的研究和实践,可以认为钢桥的技术和开发已经成熟。如今仍然存在两个挑战,第一个是开发更有效的结构体系和施工技术以降低成本。第二个是维护现有的钢桥,使其在整个使用寿命中都能有效地发挥作用。 | 藤野陽三 Dionysius Siringoringo | 2020 | 钢结构(中英文)2020,35,1: | 1 |

| 15 | Gracilaria fisheri oligosaccharides ameliorate inflammation and colonic epithelial barrier dysfunction in mice with acetic acid-induced colitis显示文摘Objective:To investigate the effect of Gracilaria fisheri oligosaccharides(GFO)on inflammation and colonic epithelial barrier dysfunction in colitis mice.Methods:The animals were treated by oral gavage with distilled water,1000 mg/kg inulin,100,500,or 1000 mg/kg GFO for 14 d,or treated with 50 mg/kg mesalamine for 5 d after colitis induction(on day 10).Histopathology,inflammatory cytokines,colonic permeability,and tight junction proteins were investigated by hematoxylin and eosin staining,immunohistochemical staining,Ussing chamber technique,and Western blotting assays,respectively.Results:GFO ameliorated histological damage in colitis mice when compared to untreated colitis mice.Treatments with 100,500,and 1000 mg/kg GFO reduced TNF-αexpression,while IL-1βwas significantly reduced in colitis mice treated with 500 and 1000 mg/kg.Compared to untreated colitis mice,GFO increased transepithelial electrical resistance,reduced fluorescein isothiocyanate-dextran paracellular flux,and modulated tight junction proteins(occludin and claudin 2)in colitis mice.Conclusions:GFO has anti-inflammatory activity and could modulate colonic epithelial barrier dysfunction in acetic acid-induced colitis mice.Furthermore,GFO could modulate the expression of tight junction proteins that play important roles in colonic barrier function. | Brenda Siringoringo Nawiya Huipao Chittipong Tipbunjong Jongdee Nopparat Santad Wichienchot Albert M.Hutapea Pissared Khuituan | 2021 | Asian Pacific Journal of Tropical Biomedicine2021,11,10: | 0 |
