1Voltage rise mitigation for solar PV integration at LV grids Studies from PVNET.dk显示文摘Solar energy from photovoltaic(PV)is among the fastest developing renewable energy systems worldwide.Driven by governmental subsidies and technological development,Europe has seen a fast expansion of solar PV in the last few years.Among the installed PV plants,most of them are situated at the distribution systems and bring various operational challenges such as power quality and power flow management.The paper discusses the modelling requirements for PV system integration studies,as well as the possible techniques for voltage rise mitigation at low voltage(LV)grids for increasing PV penetration.Potential solutions are listed and preliminary results are presented.Guangya YANG Francesco MARRA Miguel JUAMPEREZ Søren Bækhøj KJÆR Seyedmostafa HASHEMI JacobØSTERGAARD Hans Henrik IPSEN Kenn H.B.FREDERIKSEN 2015Journal of Modern Power Systems and Clean Energy2015,3,3:5
2大熊猫粪便类固醇激素的保存时效性及检测准确性研究显示文摘对大熊猫类固醇激素的监测有助于了解其生存环境的状况,然而,野外采集的粪便样品的时间尚缺乏准确估计,因此,样品中有效保存的时间与分析量是否对检测结果具有影响尚不得而知。为评估样品分析量和保存时间对野生大熊猫粪便样品类固醇激素结果的影响,我们设置0.5g和0.2g两种样品分析量,以及模拟野外温度(13±2℃)环境下,进行连续360 h的检测分析。结果表明:不同样品分析量(即0.5g和0.2g)间差异显著(p=0.000),且分析量越大检测结果越准确。雄性大熊猫的皮质醇可稳定保存48h(F=6.08,P<0.05),睾酮未出现显著性变化(F=0.813,P>0.05),结果在360 h内具有可比性;雌性大熊猫的皮质醇可稳定保存72 h(F=5.96,P<0.05),孕酮可稳定保存48 h(F=2.365,P<0.05)。在实际应用中,对于非新鲜的大熊猫粪便样品应根据不同检测目的在样品保存的有效期内进行类固醇激素的准确检测。毕温磊 杨志松 陈鹏 陈超 冯菲菲 Jacob R Owens 侯蓉 张志和 李明喜 齐敦武 2016西华师范大学学报(自然科学版)2016,37,2:5
3大熊猫GPS项圈行为数据的分类阈值显示文摘在大熊猫(Ailuropoda melanoleuca)研究中,利用GPS项圈研究活动节律已经得到广泛应用。但是,由于对GPS项圈行为数据的分类阈值一直缺乏研究,导致了大熊猫个体活动节律分析结果出现一定的偏差。本文以半野化过渡训练区内2只佩戴GPS项圈(Lotek_7000 MU)的大熊猫('倩倩'与'和盛')为研究对象,通过监控视频观测获得休息与活动行为时间段,对比同期利用GPS项圈行为数据计算得到的运动指数,采用正判率最大化策略,确定大熊猫休息和活动两类行为运动指数的行为分类阈值。结果表明,大熊猫休息状态和活动状态运动指数的行为分类阈值为32,而之前研究中采用0作为阈值。以32为阈值对行为分类,其中,休息行为正判率为98.23%,运动行为正判率94.48%;而以0为阈值,休息行为正判率为100%,运动行为正判率77.34%。利用阈值32和0对两只大熊猫19 d的休息行为和活动行为进行分类识别。以0为阈值时,大熊猫日平均活动率('倩倩'为59%;'和盛'为70%),高于以32为阈值得到的日平均活动率('倩倩'为54%;'和盛'为50%),这表明以0为行为分类阈值时,会高估大熊猫活动率。何可 杨志松 青菁 何流洋 戴强 齐敦武 毕温磊 Jacob R Owens 古晓东 杨旭煜 2016动物学杂志2016,51,2:5
4月季对根结线虫病抗性遗传研究(英文)显示文摘针对月季栽培过程中出现的最严重的根结线虫病防治问题 ,开展了月季对根结线虫抗性遗传研究。研究结果如下 :①对常用的 4种月季砧木R .multifloraK1 ,K2 ,CE63及R .indica对 4种常见根结线虫即南方根结线虫 (Meloidogyneincognita)、爪哇根结线虫 (M .javanica)、花生根结线虫 (M .arenaria)及北方根结线虫 (M .hapla)的抗性进行了测定 ,得出只有北方根结线虫能侵染月季 ,其余 3种不能侵染。②根结指数与对数转化后的每克根中雌虫数、雄虫数、3~ 4龄幼虫数之和、2龄幼虫数、卵数、成虫及 3~ 4龄幼虫数之总和、2龄幼虫与卵数之总和均呈线性相关关系 ,因此根结指数是进行抗性评价的可靠、简单及实用的指标。抗性划分标准如下 :根结指数 0 .0~ 1 .0 ,抗病 ;1 .0~ 2 .0 ,中等抗病 ;2 .0~ 3.0 ,感病 ;3.0~4.0 ,比较感病 ;4.0~ 5 .0 ,高度感病。③以根结指数为指标 ,通过对杂交所得 74个子代的抗性评价试验表明 :在 2抗性亲本所得 1 2个子代中 ,各子代抗性水平存在抗性分化 ,说明抗病基因不是由单一显性基因控制 ;在所有的 62个抗性亲本与感病亲本的杂交子代中 ,5 9个子代均比抗病亲本感病 ,表明抗病基因由隐性基因控制。因此 ,提出了月季对根结线虫的抗性遗传可能由王新荣 Jacob Y Mastrantuono S Bazzano J Minot J C Voisin R Esmenjaud D 2001华中农业大学学报2001,20,3:4
5圈养大熊猫发情期间行为变化和活动节律研究显示文摘在发情期,对动物行为时间分配和活动节律的认识将有助于濒危动物繁育质量的提高。大熊猫为季节性单次发情动物,雄性发情期可持续30 d左右,而雌性大熊猫为几天至十几天,高峰期仅为1--3 d,且有与雄性不同步发情的现象。因此,进行发情期行为学方面的研究则显得尤为重要。采用瞬时扫描取样法和全事件记录法,于2013年3月1日—4月30日对成都大熊猫繁育研究基地的8只发情期大熊猫进行行为时间变化和活动节律研究,每只每周记录2 d数据。结果表明:休息行为是发情期最主要的行为方式(雄性约46%,雌性约53%),其次是摄食和运动行为,而探究、求适和发情行为则较少,发情行为主要出现在00∶00—03∶00、09∶00—11∶00和15∶00—17∶00等3个时段,可配对交配;发情期雌雄个体在休息、求适、运动和发情行为上的差异有高度统计学意义(P〈0.01),在探究行为上的差异有统计学意义(P〈0.05),而在摄食行为上的差异则无统计学意义;且发情、探究行为与运动行为呈显著正相关(P〈0.01)。对发情期圈养大熊猫昼夜活动行为的研究将为大熊猫的人工繁育及其配种提供行为学方面的理论依据。陈超 杨志松 潘载扬 毕温磊 陈鹏 Jacob R Owens 侯蓉 张志和 古晓东 齐敦武 2015四川动物2015,34,2:4
6New oral pharmacotherapeutic agents for venous thromboprophylaxis after total hip arthroplasty显示文摘Patients undergoing total hip arthroplasty(THA)are at high risk for developing venous thromboembolism and,therefore,require short term prophylaxis with antithrombotic agents.Recently,target specific oral anticoagulants(TSOA)including the direct thrombin inhibitor,dabigatran,and the factorⅩa inhibitors rivaroxaban,apixaban,and edoxaban have been approved for THA thrombopropylaxis in various countries.The TSOAs provide a rapid acting,oral alternative to parenteral agents including low-molecular weight heparins(LMWH)and fondaparinux;and compared to warfarin,they do not require routine laboratory monitoring and possess much fewer drug-drug interactions.Based on phaseⅢclinical studies,TSOAs have established themselvesas an effective and safe option for thromboprophylaxis after THA compared to LMWH,particularly enoxaparin,but require additional evaluation in specific populations such as the renally impaired or elderly.The ability to monitor and reverse these TSOAs in the case of bleeding complications or suspected sub-or supra-therapeutic anticoagulation is of importance,but remains investigational.This review will focus on the drug-specific characteristics,efficacy,safety,and economic impact of the TSOAs for thromboprophylaxis following THA,as well as the aspects of therapeutic monitoring and anticoagulation reversal in the event of bleeding complications or a need for urgent reversal.Garrett B Aikens Jacob R Osmundson Michael P Rivey 2014World Journal of Orthopedics2014,5,3:3
7Towards a standard diet-induced and biopsy-confirmed mouse model of non-alcoholic steatohepatitis: Impact of dietary fat source显示文摘BACKGROUND The trans-fat containing AMLN(amylin liver non-alcoholic steatohepatitis,NASH)diet has been extensively validated in C57BL/6J mice with or without the Lep^ob/Lep^ob(ob/ob)mutation in the leptin gene for reliably inducing metabolic and liver histopathological changes recapitulating hallmarks of NASH.Due to a recent ban on trans-fats as food additive,there is a marked need for developing a new diet capable of promoting a compatible level of disease in ob/ob and C57BL/6J mice.AIM To develop a biopsy-confirmed mouse model of NASH based on an obesogenic diet with trans-fat substituted by saturated fat.METHODS Male ob/ob mice were fed AMLN diet or a modified AMLN diet with trans-fat(Primex shortening)substituted by equivalent amounts of palm oil[Gubra amylin NASH,(GAN)diet]for 8,12 and 16 wk.C57BL/6J mice were fed the same diets for 28 wk.AMLN and GAN diets had similar caloric content(40%fat kcal),fructose(22%)and cholesterol(2%)level.RESULTS The GAN diet was more obesogenic compared to the AMLN diet and impaired glucose tolerance.Biopsy-confirmed steatosis,lobular inflammation,hepatocyte ballooning,fibrotic liver lesions and hepatic transcriptome changes were similar in ob/ob mice fed the GAN or AMLN diet.C57BL/6J mice developed a mild to moderate fibrotic NASH phenotype when fed the same diets.CONCLUSION Substitution of Primex with palm oil promotes a similar phenotype of biopsyconfirmed NASH in ob/ob and C57BL/6J mice,making GAN diet-induced obese mouse models suitable for characterizing novel NASH treatments.Michelle L Boland Denise Oro Kirstine S T■lb■l Sebastian T Thrane Jens Christian Nielsen Taylor S Cohen David E Tabor Fiona Fernandes Andrey Tovchigrechko Sanne S Veidal Paul Warrener Bret R Sellman Jacob Jelsing Michael Feigh Niels Vrang James L Trevaskis Henrik H Hansen 2019World Journal of Gastroenterology2019,25,33:3

9Interaction of IFNL3 with insulin resistance,steatosis and lipid metabolism in chronic hepatitis C virus infection显示文摘Metabolic changes are inextricably linked to chronic hepatitis C(CHC).Recently polymorphisms in the IFNL3(IL28B)region have been shown to be strongly associated with spontaneous and treatment induced recovery from hepatitis C virus(HCV)infection.Further,circumstantial evidence suggests a link between IFNL3single nucleotide polymorphisms and lipid metabolism,steatosis and insulin resistance in CHC.The emerging picture suggests that the responder genotypes of IFNL3polymorphisms are associated with a higher serum lipid profile,and less frequent steatosis and insulin resistance.This review analyzes the current data regarding this interaction and its meaning for HCV pathogenesis and disease progression.Mohammed Eslam David R Booth Jacob George Golo Ahlenstiel 2013World Journal of Gastroenterology2013,19,41:2
