| 5 | A mixed acid methodology to produce thermally stable cellulose nanocrystal at high yield using phosphoric acid显示文摘Cellulose nanocrystal(CNC)with distinctive shape-morphology,enhanced thermal stability and dispersibility is essential for overcoming the challenges in processing polymer/CNC nanocom-posites through melt compounding at elevated temperatures.This study shows a mixed acid hy-drolysis method to produce CNC with improved thermal stability and high productivity.The use of phosphoric acid(H_(3)PO_(4)),as a mild acid,in combination with a strong acid either sulphuric acid(H_(2)SO_(4))or hydrochloric acid(HCl)leads to reduced use of strong acids and low impact on our environment.The influences of acid combination and sequence of addition on the production yield were investigated by retaining the proportion of H_(3)PO_(4)to corrosive acid(H_(2)SO_(4)and HCl)4 to 1,and solid to liquid ratio 1꞉75.This methodology has enabled to isolate CNC with higher thermal stability,dispersibility and productivity in terms of amount acid used 1 g of CNC,as compared with single acid hydrolysis.The CNC produced using the combination of H_(3)PO_(4)and HCl exhibits high thermal stability,dispersibility and rod-like shape morphology with length and width of(424±86)and(22±3)nm,respectively.Moreover,this approach has reduced H_(3)PO_(4)consumption by 54%as compared with single acid hydrolysis method for the production of same amount of CNC. | Khairatun Najwa Mohd Amin Alireza Hosseinmardi Darren J.Martin Pratheep K.Annamalai | 2022 | Journal of Bioresources and Bioproducts2022，7，2： | 1 |

| 7 | Bank erosion in an Andean páramo river system: Implications for hydro-development and carbon dynamics in the neotropical Andes显示文摘The páramo of the Northern Andes provide critically important ecosystem services to the Northern Andean region in the form of water provisioning and carbon sequestration, both of which are a result of the páramo?s organic-rich soils. Little is known, however, about the hydro-geomorphic characteristics of the rivers that drain these ecosystems. With impending plans for widespread hydro-development and increasing implementation of carbon-sequestering compensation for ecosystem services programs in the region it is imperative that we develop a thorough understanding of the hydrogeomorphic role that rivers play in this unique ecosystem. The objective of this study was to quantify bank erosion along an Amazonian headwater stream draining a small, relatively undisturbed páramo catchment to gain a better understanding of the natural erosion regime and the resulting sediment contributions from this unique ecosystem. This study implemented a combination of field, laboratory, and Geographic Information Systems techniques to quantify bank erosion rates and determine a bank erosion sediment yield from the Ningar River, a small páramo catchment(22.7 km^2) located in the eastern Andean cordillera of Ecuador. Results show that bank erosion rates range from 3.0 to ≥ 390.0 mm/yr, are highly episodic, and yield at least 487 tons of sediment annually to the Ningar River. These results imply that 1) páramo ecosystems substantially contribute to the sediment load of the Amazon River basin; 2) bank erosion is a potentially significant flux component of basin-scale carbon cycles in páramo ecosystems; and 3) hydrologic alteration campaigns(dam building) will likely critically alter these contributions and concomitantly disconnect a critical source of sediment and nutrients to downstream ecosystems. | Derek J.MARTIN Christopher ELY Beverley C.WEMPLE | 2019 | Journal of Mountain Science2019，16，2： | 1 |
| 8 | Applying the Socio-Ecological Model to barriers to implementation of ACL injury prevention programs: A systematic review显示文摘Background: Preventing anterior cruciate ligament(ACL) injuries is important to avoid long-term adverse health consequences. Identifying barriers to implementation of these prevention programs is crucial to reducing the incidence of these injuries. Our purpose was to identify barriers of implementation for ACL injury prevention programs and suggest mechanisms for reducing the barriers through application of a SocioEcological Model(SEM).Methods: Studies investigating ACL prevention program effectiveness were searched in Medline via PubMed and the Cochrane Library, and a subsequent review of the references of the identified articles, yielded 15 articles total. Inclusion criteria encompassed prospective controlled trials, published in English, with ACL injuries as the primary outcome. Studies were independently appraised by 2 reviewers for methodological quality using the PEDro scale. Barriers to implementation were identified when reported in at least 2 separate studies. A SEM was used to suggest ways to reduce the identified barriers.Results: Five barriers were identified: motivation, time requirements, skill requirements for program facilitators, compliance, and cost. The SEM suggested ways to minimize the barriers at all levels of the model from the individual through policy levels.Conclusion: Identification of barriers to program implementation and suggesting how to reduce them through the SEM is a critical first step toward enabling ACL prevention programs to be more effective and ultimately reducing the incidence of these injuries. | DRima L.Bogardus Ryan J.Martin Alice R.Richman Anthony S.Kulas | 2019 | Journal of Sport and Health Science2019，8，1： | 1 |

| 18 | 小型船舶上的液化石油气用具—火灾事故调查显示文摘在美国西北太平洋地区的一次野外垂钓活动中,一名游客在向导的渔船中由于爆燃而严重受伤。事故的调查表明,燃油供应商销售并在渔船中安装了非标准的液化石油气加热系统,该系使用的元件未达到液化石油气的使用标准。如果使用了正确的加热系统,同时向导能够根据安全预防常识及时观察到易燃燃料的状况,那么这起事故是完全可以避免的。本文阐述了对此事故的调查,并希望提醒船只使用者和海洋专业人员能明白使用非标准燃油输运元件的内在危险性。 | Richard J.Martin Feifei Zhang Brad A.McGoran William D.Chapman | 2007 | 金属热处理2007，32，z1： | 0 |
| 19 | 碳酸盐岩储层中岩石物理流动单元的特征显示文摘一种确定和描述岩石物理流动单元特征的方法有助于解决碳酸盐岩储层勘探和生产过程中面临的某些关键问题。这种模式的运用揭示、了解和预测碳酸盐岩储层动态的一个关键因素是将它们表示为不同流动单元的综合,这些单元带有均匀的孔喉尺寸分布和类似的动态。如果在沉积岩相和流动单元之间存在关系,就可以提出共同的地质和工程分带方案。随后,可以从岩石物理流动单元的角度描述准层序的特征。综合含水饱和度、碳氢化合物柱高度以及这些流动单元与研究区域解释的层序地层学的关系,就可提供一种有用的工具,作出储层动态单元图件,预测地层圈闭的位置。对管理正在生产的储层,开发遗漏的产层,以及建立模拟前动态预测,都具有意义。 为了说明这种方法,我们采用了5个实例;中东灰岩,利用模式确定具有明显不同动态的储层带,单独从测井孔隙度看,其特征不明显;Williston盆地Madison碳酸盐岩,我们证实所预测的白云质粒状灰岩中地层圈闭的潜力;中部大陆Lansing Kansas City模孔灰岩,利用模式确定井中高含水饱和带之下的生产产层(这个地区没有现代测井或者岩心);二叠盆地Howard Glasscok油田的San Andres白云岩,在成熟的生产区确定遗漏的产层;二叠盆地另一实例,Dagger Draw油田的Cisco白云岩的解释表明怎样在发育次生孔隙? | Alden J.Martin 付文敏 李祜佑 | 1998 | 天然气勘探与开发1998，0，1： | 0 |
