1土地利用对土壤性质影响的区域差异研究显示文摘【目的】研究探讨土地利用对土壤性质影响的区域差异性。【方法】选择4类土地利用方式(天然林、人工林、灌丛和耕地),分别在山西寿阳县和四川丹棱县野外采集土壤样方进行测定,利用统计分析法研究土地利用对土壤性质影响的区域差异。【结果】不同土地利用方式对土壤性质的影响差异显著。人类活动干扰小的土地利用方式的土壤有机质、全氮含量和含盐量等普遍高于人类影响较强的土地利用方式。相同的土地利用方式对土壤性质的影响具有空间差异。即便在相同的土地利用方式下,不同的耕作制度和田间管理措施(灌溉、施肥、农药等)也会造成土壤特性的区域异质性。【结论】不同土地利用方式对土壤性质影响的区域差异揭示了人类活动对环境变化影响的区域差异,可以在一定程度上解释'人-地'的复杂性关系,研究结果可为国家在区域土地规划、作物栽培布局和水土保持政策制订等提供科学依据。吴文斌 杨鹏 唐华俊 Ongaro Luca Shibasaki Ryosuke 2007中国农业科学2007,40,8:69
2Interactions between Axillary Branches of Arabidopsis显示文摘顶端的优势的研究在豌豆和豆子,射击系统在被整修回到叶子极大地得益于二分支的试金仅仅二活跃 cotyledonary 腋的分支。在这些二分支的射击,证据的大身体证明一个活跃地成长的分支能禁止其它的生长,推动禁止的信号的性质上的研究,它仍然糟糕被理解。这里,我们在 Arabidopsis 描述二分支的试金的建立,用跑的茎上的连续分支。就象在豌豆和豆子的古典研究,这些连续分支能禁止对方的生长。上面的分支能不仅禁止更低的分支,而且更低的分支能禁止上面的分支,说明禁止的信号的双向行动。用异种,当抑制清楚地越过stem from 被播送时,我们证明抑制部分依赖于 MAX 小径和那对禁止的分支活跃,二个分支的脉管的连接是弱的,并且 MAX 小径能够在茎单方地行动。Veronica Ongaro Katherine Bainbridge Lisa Williamson Ottoline Leyser 2008Molecular Plant2008,1,2:6
3Molecular classifications of gastric cancers: Novel insights and possible future applications显示文摘Despite some notable advances in the systemic management of gastric cancer(GC), the prognosis of patients with advanced disease remains overall poor and their chance of cure is anecdotic. In a molecularly selected population, a median overall survival of 13.8 mo has been reached with the use of human epidermal growth factor 2(HER2) inhibitors in combination with chemotherapy, which has soon after become the standard of care for patients with HER2-overexpressing GC. Moreover, oncologists have recognized the clinical utility of conceiving cancers as a collection of different molecularlydriven entities rather than a single disease. Several molecular drivers have been identified as having crucial roles in other tumors and new molecular classifications have been recently proposed for gastric cancer as well. Not only these classifications allow the identification of different tumor subtypes with unique features, but also they serve as springboard for the development of different therapeutic strategies. Hopefully, the application of standard systemic chemotherapy, specifictargeted agents, immunotherapy or even surgery in specific cancer subgroups will help maximizing treatment outcomes and will avoid treating patients with minimal chance to respond, therefore diluting the average benefit. In this review, we aim at elucidating the aspects of GC molecular subtypes, and the possible future applications of such molecular analyses.Silvio Ken Garattini Debora Basile Monica Cattaneo Valentina Fanotto Elena Ongaro Marta Bonotto Francesca V Negri Rosa Berenato Paola Ermacora Giovanni Gerardo Cardellino Mariella Giovannoni Nicoletta Pella Mario Scartozzi Lorenzo Antonuzzo Nicola Silvestris Gianpiero Fasola Giuseppe Aprile 2017World Journal of Gastrointestinal Oncology2017,9,5:5
4基于尺度推绎法的生态脆弱区粮食作物耕作适宜性评价(摘要)(英文)显示文摘[目的]对以生态脆弱及半干旱气候为典型特征的寿阳县进行农作物土地适宜性评价,以期为农田的可持续发展提供理论依据。[方法]针对研究区寿阳县的当地作物玉米、小麦、高粱和大麦,通过尺度推绎方法开展了传统及机械种植两种情景下的土地耕作适宜性评价。尺度推绎在一个土地系统中完成,该系统由土地单元、土地面和土地点几级空间系统组成。并通过气候调整指数修正了IAO(意大利海外农业研究所)的土地适宜性评价方法。[结果]4种作物种植适宜性出现了两极化现象:4种作物的最适宜等级(S1)和最不适宜等级(N2)在研究区占大部分地区。玉米、大麦和小麦在传统模式下更适宜耕作。[结论]未来的耕作政策应更加注重在非宜耕区实现耕地向林地与草地的转变,在宜耕区加大农业生产的投入,注意提高牧民生活与环境保护的平衡,以维持一个健康、稳定的生态系统。何英彬 Luca Ongaro 王毅敏 2009Agricultural Science & Technology2009,10,6:4
5基于尺度推绎方法的生态脆弱区耕作适宜性研究显示文摘以山西寿阳县的玉米和小麦为研究对象,应用尺度推绎方法开展机械化与传统耕作方式下区域粮食作物耕作适宜性的对比研究。结果表明:(1)传统耕作方式下玉米与小麦适宜种植面积皆要大于机械化耕作方式下2种作物适宜种植面积,而无论是机械化种植还是传统耕作小麦适宜种植区面积皆大于玉米种植适宜区;(2)2种作物种植适宜区空间分布呈两极化特征,即高度适宜区与永久非适宜区占据研究区绝大部分区域;(3)2种粮食作物高度种植适宜区基本集中在寿阳县北部黄土高原的塬、沟地貌区及坡度较小的山区。建议在机械化种植与传统耕作方式下皆是中、高度种植适宜区域采取机械化种植方式,而在仅适宜传统耕作的种植适宜区采取传统方式耕作。何英彬 姚艳敏 唐华俊 杨鹏 王利民 邓辉 Luca Ongaro 2011中国农学通报2011,27,1:4
6Estimation of the effective properties of two-dimensional cellular materials:a review显示文摘In a vast number of engineering fields like medicine,aerospace or robotics,materials are required to meet unusual performances that simple homogeneous materials are often not able to fulfil.Consequently,many efforts are currently devoted to develop future generations of materials with enhanced properties and unusual functionalities.In many instances,biological systems served as a source of inspiration,as in the case of cellular materials.Commonly observed in nature,cellular materials offer useful combinations of structural properties and low weight,yielding the possibility of coexistence of what used to be antagonistic physical properties within a single material.Due to their peculiar characteristics,they are very promising for engineering applications in a variety of industries including aerospace,automotive,marine and constructions.However,their use is conditional upon the development of appropriate constitutive models for revealing the complex relations between the microstructure's parameters and the macroscopic behavior.From this point of view,a great variety of analytical and numerical techniques have been proposed and exhaustively discussed in recent years.Noteworthy contributions,suggesting different assumptions and techniques are critically presented in this review paper.Federica Ongaro 2018Theoretical & Applied Mechanics Letters2018,8,4:2

15朝向中国的多层级治理?——应对跨行政辖区和跨区域组织间的复杂公共事务显示文摘本文探讨了在进行有效调整和限制的条件下,多层级治理的概念框架对中国政治行政体制的可适用性。多层级治理在中国的应用能够解释全球影响和非政府力量在公共政策制定中的参与。本文认为多层级治理的发展可能是新权威主义条件下提高政治体制的社会合法性的一种方式。我们提出一种吸引人但也可能存在过度延伸的假设,即多层级治理的发展可能是在中国建立政治合法性过程中的重要部分,正如它可能成为欧洲探索重建陷入困境的传统自由民主制度的一个路径。中国和欧洲可能会采用多层级治理以加强各自政治制度的合法性并强化其基础。这预示者对多层级治理极强的规范性和目的性的应用。Edoardo Ongaro 公婷 敬乂嘉 陈阳(译) 周霓羽(译) 2018复旦公共行政评论2018,0,2:1
