| 2 | 土壤旋切振动减阻的有限元分析显示文摘提出了一种对旋耕机具施加振动载荷进行压实土壤切削减阻的方法。对板结土壤参数进行土壤三轴测试试验,结合LS-DYNA的MAT147材料模型,测试土壤材料模型参数,并建立了南方丘陵地带板结土壤本构模型及土壤振动旋切过程的有限元数值模型。通过三维数值模拟和计算,分析了外加激励的振型、频率及振幅等因素对土壤切削阻力的影响及变化规律,并得到实现最优减阻效果的各项参数组合。研究结果表明,采用振动旋耕机具进行土壤作业过程中,选择合适振动频率、幅值以及振动类型的外加刀具振动能实现土壤耕作减阻,有效降低机具的土壤切削功率。 | 蒋建东 高洁 赵颖娣 Willem Hoogmoed 张宪 | 2012 | 农业机械学报2012,43,1: | 43 |
| 3 | Fecal microbiota transplantation as novel therapy in gastroenterology:A systematic review显示文摘AIM:To study the clinical efficacy and safety of Fecal microbiota transplantation(FMT).We systematically reviewed FMT used as clinical therapy.METHODS:We searched MEDLINE,EMBASE,the Cochrane Library and Conference proceedings from inception to July,2013.Treatment effect of FMT was calculated as the percentage of patients who achieved clinical improvement per patient category,on an intention-to-treat basis.RESULTS:We included 45 studies;34 on Clostridium difficile-infection(CDI),7 on inflammatory bowel disease,1 on metabolic syndrome,1 on constipation,1 on pouchitis and 1 on irritable bowel syndrome(IBS).In CDI 90% resolution of diarrhea in 33 case series(n = 867) was reported,and 94% resolution of diarrhea after repeated FMT in a randomized controlled trial(RCT)(n = 16).In ulcerative colitis(UC) remission rates of 0% to 68% were found(n = 106).In Crohn's disease(CD)(n = 6),no benefit was observed.In IBS,70% improvement of symptoms was found(n = 13).100% Reversal of symptoms was observed in constipation(n = 3).In pouchitis,none of the patients(n = 8) achieved remission.One RCT showed significant improvement of insulin sensitivity in metabolic syndrome(n = 10).Serious adverse events were rare.CONCLUSION:FMT is highly effective in CDI,and holds promise in UC.As for CD,chronic constipation,pouchitis and IBS data are too limited to draw conclusions.FMT increases insulin sensitivity in metabolic syndrome. | Noortje G Rossen John K Mac Donald Elisabeth M de Vries Geert R D'Haens Willem M de Vos Erwin G Zoetendal Cyriel Y Ponsioen | 2015 | World Journal of Gastroenterology2015,21,17: | 41 |
| 4 | 基于ALE有限元仿真的土壤切削振动减阻显示文摘针对浙江省茶园土壤压实问题造成小型茶园作业机功率不足问题,提出了茶园振动深松的土壤作业方法。以浙江龙井茶园压实土壤为分析对象,针对土壤深耕铲-土壤切削过程的动力学数值仿真,建立了土壤静态切削力学模型,并进行了土壤大变形切削的屈服失效分析。采用ALE算法模拟了土壤静态切削中深耕铲的切削阻力变化情况,建立了深耕铲-土壤的三维有限元模型并分析了振动切削的振动类型、频率、振幅以及深耕铲的前进速度对土壤切削阻力降低的关系,得出了振动频率和振幅对切削力的影响规律。进一步研究了不同的振动切削条件下,振动类型和刀具的切削速度对切削阻力的影响,通过合理选取一定的深松铲外加振动激励的振幅和频率能够得到最小的切削阻力,实例分析证明,振动频率取为25Hz,振幅为14mm时,振动切削的插入阻力能达到最小,切削阻力能降低约22%。上述研究结果为土壤振动切削减阻的外加振源参数优化提供了设计依据。 | 蒋建东 高洁 赵颖娣 Willem Hoogmoed 张立彬 | 2012 | 农业工程学报2012,28,S1: | 37 |

| 13 | A Technological Overview of Biogas Production from Biowaste显示文摘当今时代,人类对化石燃料的不合理利用和温室气体对环境的影响,使研究者关注有机资源和垃圾的可持续能源转化。全球的能源需求非常大,主要能源来自化石能源。目前的研究认为厌氧消化是一种高效的可替代技术,其既能产生生物燃料,又能可持续地处理垃圾。在沼气工业,为了促进沼气的生成和提高质量,有几种不同的技术趋势。然而,投资厌氧消化的成功取决于原料成本低和沼气使用范围广(热能、电能和燃料)。在欧洲能源市场,沼气的生产一直在增长,为生物能源的发展提供了一条经济的替代选择。本文的目的是对由木质纤维素类的生物垃圾生产沼气进行综述,为沼气经济提供重要信息。 | Spyridon Achinas Vasileios Achinas Gerrit Jan Willem Euverink | 2017 | Engineering2017,3,3: | 8 |
| 14 | Management and therapy of vasovagal syncope: A review显示文摘Vasovagal syncope is a common cause of recurrent syncope. Clinically, these episodes may present as an isolated event with an identifiable trigger, or manifest as a cluster of recurrent episodes warranting intensive evaluation. The mechanism of vasovagal syncope is incompletely understood. Diagnostic tools such as implantable loop recorders may facilitate the identification of patients with arrhythmia mimicking benign vasovagal syncope. This review focuses on the management of vasovagal syncope and discusses the non-pharmacological and pharmacological treatment options, especially the use of midodrine and selective serotonin reuptake inhibitors. The role of cardiac pacing may be meaningful for a subgroup of patients who manifest severe bradycardia or asystole but this still remains controversial. | Muhammet Ali Aydin Tushar V Salukhe Iris Wilke Stephan Willems | 2010 | World Journal of Cardiology2010,2,10: | 8 |
| 15 | Double balloon endoscopy associated pancreatitis:A description of six cases显示文摘AIM:To perform a single-center analysis of all double balloon endoscopy (DBE) related cases of pancreatitis identified prospectively from a recorded DBE-complication database. METHODS:From November 2003 until January 2007, 603 DBE procedures were performed on 412 patients, with data on complications recorded in a database. The setting was a tertiary care center offering DBE. DBE was performed from the antegrade or retrograde route. Out-come measurements included age, gender, medication, indication, DBE-endoscope type, insertion depth, proce-dure duration, findings, interventions, post-procedural abdominal pain, and post-procedural hospitalization. RESULTS:This is the largest single-center study report-ing on post-DBE pancreatitis prospectively. Six patients (1.0%) developed post-DBE pancreatitis, all after antegrade DBE. There was no association with gender, duration of the procedure or type of endoscope. The mean age was 51.9 years (range 25-78). Four patients had severe pancreatitis. Of these, two had inflammatory signs in the body-tail region, one had pancreatitis in the tail region, and the total pancreas was involved in one. CONCLUSION:The incidence of post-DBE pancreatitis in our series is higher than previously reported. We found no relation with DBE-endoscope type. The inflammatory changes occurred in the body-tail region of the pancreas, suggesting that post-DBE pancreatitis is caused by repetitive mechanical strain on the pancreas. | Soeresh VA Jarbandhan Stijn JB van Weyenberg Willem M van der Veer Dimitri GN Heine Chris JJ Mulder Maarten AJM Jacobs | 2008 | World Journal of Gastroenterology2008,14,5: | 8 |

| 17 | Genomic imbalances in esophageal carcinoma cell lines involve Wnt pathway genes显示文摘AIM:To identify molecular markers shared across South African esophageal squamous cell carcinoma(ESCC) cell lines using cytogenetics,fluorescence in situ hybridization(FISH) and single nucleotide polymorphism(SNP) array copy number analysis.METHODS:We used conventional cytogenetics,FISH,and multicolor FISH to characterize the chromosomal rearrangements of five ESCC cell lines established in South Africa.The whole genome copy number profile was established from 250K SNP arrays,and data was analyzed with the CNAT 4.0 and GISTIC software.RESULTS:We detected common translocation breakpoints involving chromosomes 1p11-12 and 3p11.2,the latter correlated with the deletion,or interruption of the EPHA3 gene.The most significant amplifica-tions involved the following chromosomal regions and genes:11q13.3(CCND1,FGF3,FGF4,FGF19,MYEOV),8q24.21(C-MYC,FAM84B),11q22.1-q22.3(BIRC2,BIRC3),5p15.2(CTNND2),3q11.2-q12.2(MINA) and 18p11.32(TYMS,YES1).The significant deletions included 1p31.2-p31.1(CTH,GADD45α,DIRAS3),2q22.1(LRP1B),3p12.1-p14.2(FHIT),4q22.1-q32.1(CASP6,SMAD1),8p23.2-q11.1(BNIP3L) and 18q21.1-q21.2(SMAD4,DCC).The 3p11.2 translocation breakpoint was shared across four cell lines,supporting a role for genes involved at this site,in particular,the EPHA3 gene which has previously been reported to be deleted in ESCC.CONCLUSION:The finding that a significant number of genes that were amplified(FGF3,FGF4,FGF19,CCND1 and C-MYC) or deleted(SFRP2 gene) are involved in the Wnt and fibroblast growth factor signaling pathways,suggests that these pathways may be activated in these cell lines. | Jacqueline Brown Hannelie Bothma Robin Veale Pascale Willem | 2011 | World Journal of Gastroenterology2011,17,24: | 7 |
| 18 | Improving the quantification of waterfowl migration with remote sensing and bird tracking显示文摘Accurately quantifying waterfowl migration patterns is pertinent to monitor ecosystem health and control bird-borne infectious diseases. In this review, we summarize the current understanding of the environmental mechanisms that drive waterfowl migration and then investigate the effect of intra- and inter-annual change in food supply and temperature(e.g., climate change) on their migration patterns. Recent advances in remote sensing and animal tracking techniques make it possible to monitor these environmental factors over a wide range of scales and record bird movements in detail. The synergy of these techniques will facilitate substantial progress in our understanding of the environmental drivers of bird migration. We identify prospects for future studies to test existing hypotheses and develop models integrating up-todate knowledge, high-resolution remote sensing data and high-accuracy bird tracking data. This will allow us to predict when waterfowl will be where, in response to shortand long-term global environmental change. | Yali Si Qinchuan Xin Herbert H.T.Prins Willem F.de Boer Peng Gong | 2015 | Science Bulletin2015,60,23: | 6 |
