1杂草稻落粒粳的抗逆境特性研究显示文摘杂草稻落粒粳(Oryzasativa)发生在我国辽宁丹东.落粒粳植株明显高于当地大多数栽培品种,颖果呈中长型,成熟后容易掉粒;果壳稻草色或黄间黑灰色,小穗无芒或有芒,芒长4~12cm ;颖果千粒重2 . 35 g ,种皮桔红色.落粒粳种子在13~38℃条件下的发芽率均大于88% ,水层2 . 5~10cm处理,落粒粳植株干重减少5. 0 %~6 .9% .在幼苗期,落粒粳对无芒稗的各项影响因子均明显大于化感潜力品种I kung pao ,表明落粒粳无化感作用.落粒粳可以忍耐0. 5 %的盐碱.余柳青 A.Martin Mortimer 玄松南 陆永良 周勇军 2005应用生态学报2005,16,4:54
2大学生幽默风格与精神健康关系的初步研究显示文摘目的:测试幽默风格量表在中国大学生中的信度和效度,探讨幽默风格与精神健康之间的关系。方法:354名大学生接受幽默风格量表和症状自评量表(SCL-90)的问卷调查,4周后74名大学生重新填写幽默风格量表。结果:幽默风格量表所提出的4个因子结构在中国人的样本中也存在,该量表的信度和效度可接受。中国被试在4个子量表的得分均低于加拿大被试的得分。亲和型幽默、自强型幽默得分与症状自评量表的子量表以及总体症状指数得分全部呈现负相关,而嘲讽型幽默和自贬型幽默得分与症状自评量表的子量表以及总体症状指数得分全部呈现正相关。结论:(1)该量表的初步测试效度和信度可接受,但须结合中国文化作进一步的修订;(2)亲和型和自强型幽默有益于精神健康,但嘲讽型和自贬型幽默有害于精神健康;(3)中国人与加拿大人在幽默风格、幽默对精神健康起作用的方式上存在一定的文化差异。陈国海 Rod A.Martin 2007心理科学2007,30,1:57
3应对幽默量表在354名中国大学生中的初步测试显示文摘目的:了解应对幽默量表在我国大学生中的测试情况,比较中国人和加拿大人使用应对幽默方式的差别,探讨应对幽默与心理健康之间的关系。方法:354名大学生接受应对幽默量表和症状自评量表的问卷调查。结果:应对幽默量表在大学生中的内部一致性系数(Cronbach alpha)为0.65,重测信度为0.79。去掉项目4的应对幽默量表的内部一致性系数达0.70,初步测试效度和信度可接受。男生比女生较多使用应对幽默。与加拿大学生相比,中国大学生较少使用应对幽默。结论:去掉项目4后的该量表在中国可使用,但可考虑作进一步的修订;应对幽默的使用具有一定的跨文化差异。陈国海 Rod A.Martin 2005中国心理卫生杂志2005,19,5:16

5Estimating Pinus palustris tree diameter and stem volume from tree height,crown area and stand-level parameters显示文摘Accurate and efficient estimation of forest growth and live biomass is a critical element in assessing potential responses to forest management and environmental change.The objective of this study was to develop models to predict longleaf pine tree diameter at breast height(dbh)and merchantable stem volume(V)using data obtained from field measurements.We used longleaf pine tree data from 3,376 planted trees on 127 permanent plots located in the U.S.Gulf Coastal Plain region to fit equations to predict dbh and V as functions of tree height(H)and crown area(CA).Prediction of dbh as a function of H improved when CA was added as an additional independent variable.Similarly,predictions of V based on H improved when CA was included.Incorporation of additional stand variables such as age,site index,dominant height,and stand density were also evaluated but resulted in only small improvements in model performance.For model testing we used data from planted and naturally-regenerated trees located inside and outside the geographic area used for model fitting.Our results suggest that the models are a robust alternative for dbh and V estimations when H and CA are known on planted stands with potential for naturally-regenerated stands,across a wide range of ages.We discuss the importance of these models for use with metrics derived from remote sensing data.C.A.Gonzalez-Benecke Salvador A.Gezan Lisa J.Samuelson Wendell P.Cropper Daniel J.Leduc Timothy A.Martin 2014Journal of Forestry Research2014,25,1:12
6耐药结核病的诊断:检测的可靠性和即时性显示文摘随着耐多药结核病(MDR-TB)的出现,全球都迫切需要快速药敏试验方法。国家结核病防治规划(NTPs)可能发现很难从各种变化多样的快速检测方法中选择合适的方法。我们对最重要的方法进行综述,讨论他们的优点和缺点,侧重那些可以替代商品化系统的方法,以及基因检测技术。表型和基因型药敏试验之间的关系的仍然存在问题,原因是除了对以前已研究标准化的表型的药物敏感试验外,我们关于耐药性突变的认识仍不充分。由于某些耐药菌株生长延迟,以快速生长为基础的药敏试验准确性较差。为了实现理想的耐药监测和耐多药结核病的管理,同时使实验室的工作不超负荷,需要慎重考虑检测的适应症和可疑者的界定,同时良好的显微镜依旧非常重要并且是个挑战。迄今研究较少的醋酸荧光素活性染色技术可能提供解决办法,协调早期检测和对快速药敏试验的合理的预选择。关于方法的选择,从覆盖所有人群的前景出发,应该考虑方法的适用性和敏感性。只有推广简单、低要求的方法,或者中心化的基因型药敏试验替代,但要确保标本运输程序简单才是可行的。由于不需要原代分离培养物,药敏试验结果报告时间的轻微差别相对不重要。没有任何一种检测是绝对准确的,合理的预选择可能允许使用准确度稍差但是简单的筛查方法。传统的药敏试验将依旧是用来确诊和流行病学检测必须的。A.Van Deun A.Martin J.C.Palomino 徐彩红 刘宇红 2010国际结核病与肺部疾病杂志2010,,3:11

11A global synthesis of the effectiveness and ecological impacts of management interventions for Spartina species显示文摘Invasions by Spartina species pose serious threats to global coastal ecosystems.Although many studies have examined the effectiveness and ecological impacts of invasive Spartina management,no comprehensive global synthesis has been conducted to assess the effects of management on Spartina per se and on wider non-targets.Here,we conducted a global meta-analysis of 3,459 observations from 102 studies to quantify the effects of different management interventions(physical,chemical,biological,and integrated control)on Spartina per se and native biodiversity and environments.We found that physical measures quickly suppressed Spartina but that their effectiveness declined over time.By contrast,chemical measures decreased the abundance and growth of Spartina to a lesser degree in the early stage,but the effectiveness increased over time.Different management measures did not significantly decrease the diversity of native biota on the whole,but native-plant diversity significantly decreased with time after physical control.Different management measures did not affect abiotic factors differently.These results support the use of chemical measures to control invasive Spartina,although their effectiveness would depend on the time since the management intervention.Addressing the problem of Spartina regrowth following physical control requires improved techniques.We hold that initial states of invaders and subsequent environmental changes after management interventions should be weighed in evaluating control efficacy.Shengyu Wang Philip A.Martin Yan Hao William J.Sutherland Gorm E.Shackelford Jihua Wu Ruiting Ju Wenneng Zhou Bo Li 2023Frontiers of Environmental Science & Engineering2023,17,11:1
12Measurement and modelization of VLE of binary mixtures of propyl acetate,butyl acetate or isobutyl acetate with methanol at pressure of 0.6 MPa显示文摘The vapor–liquid equilibrium of binary mixtures of propyl acetate,butyl acetate and isobutyl acetate with methanol has been determined at a constant pressure of 0.6 MPa.Results have been modeled with the Peng–Robinson equation,a traditional cubic equation of state widely employed in chemical industries,as well as with the perturbed-chain statistical associating fluid PC-SAFT theory of Gross–Sadowski.By correlation of the binary interaction parameters of these equations,the measured vapor–liquid equilibrium data can be accurately predicted.Thus,this work shows that these models are able to represent the experimental data for systems with associating compounds via hydrogen bonding.P.Susial D.Garcia R.Susial Y.C.Clavijo A.Martin 2016Chinese Journal of Chemical Engineering2016,24,5:1

20快速培养法对结核病诊断的评价:拉丁美洲的一个多中心研究显示文摘地点:拉丁美洲的结核病(TB)诊断实验室。目的:薄层琼脂(thin-layer agar,TLA)和罗氏培养(Lowenstein-Jensen,LJ)对结核病诊断的对比评价。设计:6个实验室Ⅱ期前瞻性研究。临床诊断的TB病人样本包括痰标本和肺外结核的标本。呼吸道标本用NaOH/NALC去污;根据推荐的操作程序对所有标本进行离心,萋尼氏法进行抗酸菌(AFB)染色,用LJ和TLA法培养检查。计算两种培养基的敏感度和似然比、生长检测时间和污染率。结果:总共研究了1118份临床标本。所有AFB阳性标本培养后均检出结核分枝杆菌,AFB阴性标本中,LJ检出率为3.2%,TLA为4.4%。TLA和LJ的敏感性分别为92.6%(95%CI:87.9-95.9)和84.7%(95%CI:78.8-89.0)。阳性和阴性LR相似。TLA和LJ的污染率分别为5.1%和3.0%。TLA和LJ对培养阳性的检出平均时间分别为11.5天(95%CI: 9.3-15.0)和30.5天(95%CI:26.9-39.0)(P<0.0001)。结论:参加研究实验室的不同特点、疾病流行情况和标本处理的不同并不影响TLA和LJ的总体效果,建议不同实验室使用这种方法,因它具有可靠性和可行性。J.A.Robledo G.I.Mejía N.Morcillo L.Chacón M.Camacho J.Luna J.Zurita A.Bodon M.Velasco J.C.Palomino A.Martin F.
