目的:吸力式基础具有投资费用低、施工时间短、无噪音和可重复使用等优点,因此被广泛应用在海洋工程领域。本文针对吸力式基础设计中的关键问题,主要综述现有设计理论,指出理论缺陷,并给出设计建议。创新点:综述砂土、粘土和成层土中吸力式基础的安装、回收、基础承载力、基础沉降和服役性能中的关键科学问题和现有设计理论。方法:1.基于文献报道的现场试验和模型试验,针对吸力式基础安装过程中的沉贯阻力、临界吸力和土塞效应,评估现有设计理论的准确性;2.分析粘土和砂土中吸力式基础的完全排水、完全不排水和部分排水条件下静力和循环承载力计算理论;3.针对吸力式基础的长期服役性能,分析荷载引起的基础变形、固结沉降、循环再固结沉降和极端荷载下的"棘轮效应"。结论:1.现有的吸力式基础安装中沉贯阻力计算理论没有普适性;对于临界吸力的计算,由于没有考虑"土拱效应",理论计算值均低估了安装吸力。2.对于粘土中吸力式基础承载力的计算需要考虑循环作用下土体的强度弱化和基础-土间空隙引起的承载力降低,而砂土中基础承载力计算需要考虑排水条件的影响。3.对于吸力式基础的长期服役性能,特别是基础变形的计算,目前还缺少成熟的计算理论。

Adherence to surveillance guidelines for dysplasia and colorectal carcinoma in ulcerative and Crohn's colitis patients in the Netherlands

引用

World Journal of Gastroenterology 2009年第2期15卷 226-230页

作者： Anne F van Rijn Paul Fockens Peter D Siersema bas Oldenburg Department of Gastroenterology and Hepatology Academic Medical Center University of Amsterdam Amsterdam 1105AZ The Netherlands Department of Gastroenterology and Hepatology University Medical Centre Utrecht Utrecht 3584CX The Netherlands

AIM: To study adherence to the widely accepted surveillance guidelines for patients with long-standing colitis in the Netherlands. METHODS: A questionnaire was sent to all 244 gastroenterologists in the Netherlands. RESULTS: The response rate was 63%. Of all gastroenterologists, 95% performed endoscopic surveillance in ulcerative colitis (UC) patients and 65% in patients with Crohn's colitis. The American Gastroenterological Association (AGA) guidelines were followed by 27%, while 27% and 46% followed their local hospital protocol or no specific protocol, respectively. The surveillance was correctly initiated in cases of pancolitis by 53%, and in cases of left-sided colitis by 44% of the gastroenterologists. Although guidelines recommend 4 biopsies every 10 cm, less than 30 biopsies per colonoscopy were taken by 73% of the responders. Only 31%, 68% and 58% of the gastroenterologists referred patients for colectomy when low-grade dysplasia, high-grade dysplasia (HGD) or Dysplasia Associated Lesion or Mass (DALM) was present, respectively. CONCLUSION: Most Dutch gastroenterologists performendoscopic surveillance without following international recommended guidelines. This practice potentially leads to a decreased sensitivity for dysplasia, rendering screening for colorectal cancer in this population highly ineffective.

Urbanization in China,ca.1100-1900

Frontiers of Economics in China-Selected Publications from Chinese Universities 2018年第3期13卷 322-368页

作者： Yi Xu bas van Leeuwen Jan Luiten van Zanden College of Historical Culture and Tourism Guangxi Normal UniversityGuilin 541001China International Institute of Social History Royal Netherlands Academy of Arts and SciencesAmsterdam1019ATNetherlands Department of Economic and Social History Utrecht UniversityUtrecht3512BSNetherlands

This paper presents new estimates of the development of the urban population and the urbanization ratio for the period spanning the Song and late Qing dynasties. Urbanization is viewed, as in much of the economic historical literature on the topic, as an indirect indicator of economic development and structural change. The development of the urban system can therefore tell us a lot about long-term trends in the Chinese economy between 1100 and 1900. During the Song, the level of urbanization was high, also by international standards--the capital cities of the Song were probably the largest cities in the world. This remained so until the late Ming, but during the Qing there was a downward trend in the level of urbanization from 11%-12% to 7% in the late 18th century, a level at which it remained until the early 1900s. In our paper we analyse the role that socio-political and economic causes played in this decline, such as the changing character of the Chinese state, the limited impact of overseas trade on the urban system, and the apparent absence of the dynamic economic effects that were characteristic for the European urban system.

Silicene nanoribbons on transition metal dichalcogenide substrates： Effects on electronic structure and ballistic transport

引用

Nano Research 2016年第11期9卷 3394-3406页

作者： bas van den Broek Michel Houssa Augustin Lu Geoffrey Pourtois Valery Afanas'ev Andre Stesmans Semiconductor Physics Laboratory Department of Physics and Astronomy University of Leuven Celestijnenlaan 200 D B-3001 Leuven Belgium imec 75 Kapeldreef B-3001 Leuven Belgium Department of Chemistry Plasmant Research Group University of Antwerp B-2610 Wilrijk-Antwerp Belgium

The idea of stacking multiple monolayers of different two-dimensional materials has become a global pursuit. In this work a silicene armchair nanoribbon of width W and van der Waals-bonded to different transition-metal dichalcogenide （TMD） bilayer substrates MoX2 and WX2, where X = S, Se, Te is considered. The orbital resolved electronic structure and ballistic transport properties of these systems are simulated by employing van der Waals-corrected density functional theory and nonequilibrium Green＇s functions. We find that the lattice mismatch with the underlying substrate determines the electronic structure, correlated with the silicene buckling distortion and ultimately with the contact resistance of the two-terminal system. The smallest lattice mismatch, obtained with the MoTe2 substrate, results in the silicene ribbon properties coming close to those of a freestanding one. With the TMD bilayer acting as a dielectric layer, the electronic structure is tunable from a direct to an indirect semiconducting layer, and subsequently to a metallic electronic dispersion layer, with a moderate applied perpendicular electric field.

Low rates of adherence for tumor necrosis factor-α inhibitors in Crohn's disease and rheumatoid arthritis: Results of a systematic review

引用

World Journal of Gastroenterology 2013年第27期19卷 4344-4350页

作者： Herma H Fidder Maartje MJ Singendonk Mike van der Have bas Oldenburg Martijn GH van Oijen Department of Gastroenterology and Hepatology University Medical Center Utrecht

AIM:To investigate adherence rates in tumor necrosis factor-α (TNF-α)-inhibitors in Crohn's disease (CD) and rheumatoid arthritis (RA) by systematic review of medical literature. METHODS:A structured search of PubMed between 2001 and 2011 was conducted to identify publications that assessed treatment with TNF-α inhibitors providing data about adherence in CD and RA. Therapeutic agents of interest where adalimumab, infliximab and etanercept, since these are most commonly used for both diseases. Studies assessing only drug survival or continuation rates were excluded. Data describing adherence with TNF-α inhibitors were extracted for each selected study. Given the large variation between definitions of measurement of adherence, the definitions as used by the authors where used in our calculations. Data were tabulated and also presented descriptively. Sample size-weighted pooled proportions of patients adherent to therapy and their 95%CI were *** compare adherence between infliximab, adalimumab and etanercept, the adherence rates where graphed alongside two axes. Possible determinants of adherence were extracted from the selected studies and tabulated using the presented OR. RESULTS:Three studies on CD and three on RA were identified, involving a total of 8147 patients (953 CD and 7194 RA). We identified considerable variation in the definitions and methodologies of measuring adherence between studies. The calculated overall sample size-weighted pooled proportion for adherence to TNF-α inhibitors in CD was 70% (95%CI:67%-73%) and 59% in RA (95%CI:58%-60%). In CD the adherence rate for infliximab (72%) was highercompared to adalimumab (55%), with a relative risk of 1.61 (95%CI:1.27-2.03), whereas in RA adherence for adalimumab (67%) was higher compared to both infliximab (48%) and etanercept (59%), with a relative risk of 1.41 (95%CI:1.3-1.52) and 1.13 (95%CI:1.10-1.18) respectively. In comparative studies in RA adherence to infliximab was better than etanerce
