1Bacteriophages Isolated in China for the Control of Pectobacterium carotovorum Causing Potato Soft Rot in Kenya显示文摘Soft rot is an economically significant disease in potato and one of the major threats to sustainable potato production.This study aimed at isolating lytic bacteriophages and evaluating methods for and the efficacy of applying phages to control potato soft rot caused by Pectobacterium carotovorum.Eleven bacteriophages isolated from soil and water samples collected in Wuhan,China,were used to infect P.carotovorum host strains isolated from potato tubers showing soft rot symptoms in Nakuru county,Kenya.The efficacy of the phages in controlling soft rot disease was evaluated by applying individual phage strains or a phage cocktail on potato slices and tubers at different time points before or after inoculation with a P.carotovorum strain.The phages could lyse 20 strains of P.carotovorum,but not Pseudomonas fluorescens control strains.Among the 11 phages,Pectobacterium phage Wc5r,interestingly showed cross-activity against Pectobacterium atrosepticum and two phage-resistant P.carotovorum strains.Potato slice assays showed that the phage concentration and timing of application are crucial factors for effective soft rot control.Phage cocktail applied at a concentration of 1×10^9 plaque-forming units per milliliter before or within an hour after bacterial inoculation on potato slices,resulted in>90%reduction of soft rot symptoms.This study provides a basis for the development and application of phages to reduce the impact of potato soft rot disease.Peter Muturi Junping Yu Alice Nyambura Maina Samuel Kariuki Frantis B.Mwaura Hongping Wei 2019Virologica Sinica2019,34,3:4
2德国北部挪威云杉林可持续经营中期计划的实例分析显示文摘可持续森林经营理论为中期林业计划和收获调整提供了丰富的模型选择,其不同的方法可应用于各种特定的场合和不同经营类型。本文简要回顾了传统的森林计划方法,一种称为“多林分发展”的概念可以用于任意的经营系统,这个概念把森林看作由一系列林分组成,在每一个林分中可以预先制定多种经营措施的选项,每种选项都可以通过木材或其它产品以及消耗的资源计算出一个目标值。这种简单的概念可以应用到大量的不同森林经营场合,它为森林经营者制定切实可行的森林措施和评价森林经营计划提供方法。在本研究中,以德国北部一片包括21个小班的挪威云杉林班的一个中期计划为例,说明“多林分发展”这一经营系统在实际生产中的应用。每个小班具有不同的初始状态,每个小班预设了若干经营选项,根据小班的初始状态、生长模型为各种选项计算各时期的木材产出。在林班的水平上,经营目标方程包括两个组成部分:净现值和均衡木材收获值。用模拟退火的方法来优化总体目标方程值。优化的总体解决方案在为每个小班选定合适的经营选项的同时,在全林的水平上获得最优的经济和均衡产出组合。陈伯望 Klaus.von Gadow Frantiek Vilko Sofía Sánchez Orois 2006林业科学研究2006,19,5:4
3太阳能级硅电沉积用冰晶石熔盐的电导率和黏度(英文)显示文摘以热解碳化硼管作电导池,用固定电导池常数法研究由Na F-Al F3-Si O2构成的二元系和三元系熔盐的电导率;用扭摆法测定Na3Al F6-Si O2二元系的黏度。研究发现,所研究熔盐体系的电导率和黏度均与温度呈直线关系。Na3Al F6-Si O2二元系的电导率与Si O2含量关系曲线可分为0-10%和10%-40%(摩尔分数)两段,当SiO 2含量超过10%之后,电导率随着Si O2含量的增加而快速下降,而当Si O2含量小于10%时,电导率随着Si O2含量的增加而缓慢增加。在Si O2含量大于10%的冰晶石熔盐中添加少量的SiO 2,熔盐的黏度增加,但增加的趋势基本相同,这与熔盐中形成玻璃网状结构的离子团有关。当在冰晶石熔盐中继续增大Si O2含量到50%时,黏度发生急剧变化。Michal KORENKO Zuzana VASKOV Frantiek IMKO Michal IMURDA Marta AMBROV 石忠宁 2014Transactions of Nonferrous Metals Society of China2014,24,12:3

15Nomore blind dates with calcite: Fluid-flow vs. fault-slip along the Očkov thrust, Prague Basin显示文摘Dating of fracture-filling calcitewith U-Pb geochronology is becoming a rapidly adopted technique for determining the absolute timing of brittle deformation in the upper crust.Slickenfibre calcite is a desirable target,as it precipitates between individual fault slip displacement events,and provides additional kinematic information.Here we present a case study of slickenfibres formed on the Očkov thrust in the Lower Palaezoic Prague Basin,Bohemian Massif,utilising a combination of petrographic and in situ methods.We demonstrate that slickenfibre external textures can be preserved,whilst internally primary textures are removed by fluid infiltration and recrystallization,leading to variable U and Pb mobilisation.One slickenfibre yielded a date of ca.250 Ma,which we interpret as recording fault slip along the Očkov thrust.Another cross-cutting slickenfibre yielded more scattered U-Pb data,with an imprecise apparent age around ca.95 Ma.This slickenfibre is recrystallised,destroying the primary textures,and exhibits element mobility.The meaning of this younger apparent age is therefore questionable;whereas it likely reflects Cretaceous U and Pb mobility assisted by fluid-flow along the fault plane,it may not reflect a period of fault slip.Our results demonstrate that slickenfibre-based U-Pb dates do not unequivocally relate to fault motion,and that petrographic and elemental analyses are important requirements for interpreting calcite U-Pb data.Nick M.W.Roberts JiříŽák František Vacek JiříSláma 2021Geoscience Frontiers2021,12,4:1
