sexual reproduction is the basic way to form high genetic diversity and it is beneficial in evolution and speciation of fungi.The global diversity of teleomorphic species in Ascomycota has not been estimated.This paper estimates the species number for sexual ascomycetes based on five different estimation approaches,viz.by numbers of described fungi,by fungus:substrate ratio,by ecological distribution,by meta-DNA barcoding or culture-independent studies and by previous estimates of species in Ascomycota.The assumptions were made with the currently most accepted,“2.2–3.8 million”species estimate and results of previous studies concluding that 90%of the described ascomycetes reproduce sexually.The Catalogue of Life,species Fungorum and published research were used for data procurement.The average value of teleomorphic species in Ascomycota from all methods is 1.86 million,ranging from 1.37 to 2.56 million.However,only around 83,000 teleomorphic species have been described in Ascomycota and deposited in data repositories.The ratio between described teleomorphic ascomycetes to predicted teleomorphic ascomycetes is 1:22.Therefore,where are the undiscovered teleomorphic ascomycetes?The undescribed species are no doubt to be found in biodiversity hot spots,poorly-studied areas and species complexes.Other poorly studied niches include extremophiles,lichenicolous fungi,human pathogens,marine fungi,and fungicolous fungi.Undescribed species are present in unexamined collections in specimen repositories or incompletely described earlier spe-cies.Nomenclatural issues,such as the use of separate names for teleomorph and anamorphs,synonyms,conspecific names,illegitimate and invalid names also affect the number of described species.Interspecies introgression results in new species,while species numbers are reduced by extinctions.

syzygium cumini(L.)skeels(Madan)is widely distributed in south Asian countries,including sri Lanka,where it was naturally found.There were only few studies reported on s.cumini for its values and other benefits in sri Lanka.This study focuses on morphological characterization and the diversity of s.cumini trees in seven locations of sri Lanka.Data were collected on different morphological traits.Leaf,flower and fruit morphology showed significant differences among locations.Further,trees from Batticaloa region showed different morphology,which would potentially open a different avenue for further study to trace different cultivars across the country.Results of the diversity index and multivariate analyses indicated high diversity in morphology and antioxidant capacity of trees.The variables such as leaf area,inter-nodal length,petiole length,anther length,filament length,fruit size and pericarp thickness could be suitable candidates to investigate the morphological variation of s.cumini any further.Antioxidant capacity studies also showed significant differences among locations and trees.Fruit hue angle was positively correlated to antioxidant capacities.Finding of this study concluded that the wide distribution of s.cumini trees throughout sri Lanka in different geographical locations showed high diversity in leaf,flower and fruit morphology together with antioxidant capacity.

Hardness-Based Non-destructive Method for Developing Location specific s-N Curves for Fatigue Life Evaluation

引用

Journal of Civil Engineering and Architecture 2016年第2期10卷 183-191页

作者： Chaminda s. Bandara sudath C. siriwardane Udaya I. dissanayake Ranjith dissanayake Department of Civil Engineering University of Peradeniya Peradeniya 20400 Sri Lanka Department of Mechanical and structural Engineering and Material science Faculty of Science and Technology University ofStavanger Stavanger N-4036 Norway

This paper first describes the importance of using location specific s-N curves for fatigue damage assessment of existing steel structures. It discusses the existing concepts and methods for developing s-N curves using empirical formulae and monotonic strength parameters, such as the ultimate tensile strength and hardness. It also discusses relationships among these monotonic parameters. Then it presents formulae for developing hardness-based full range s-N curves for medium strength steels. The formulae are verified using experimental data obtained from both monotonic and cyclic testing. Finally, it describes the advantages of these hardness-based formulae for developing location specific s-N curves as hardness testing is a non-destructive test which can be carried out on specific locations in structures.

suitable speed limit is important for providing safety for road users. Lower-than-required posted speed limits could cause the majority of drivers non-compliant and higher-than-required posted speed limits may also increase the number of crashes with related severities. The speed limit raised in Kansas from 70 mph to 75 mph on a number of freeway segments in 2011. The goal of this study is to assess the safety impacts of the freeway sections influenced by speed limit increase. Three years before and three years after speed limit increase was considered and three methods were used: 1-Empirical Bayes (EB), 2-before-and-after with comparison group, and 3-cross-sectional study. The Crash Modification Factors (CMFs) were estimated and showed 16 percent increase for total crashes according to EB method. Further, the before-and-after with comparison group method showed 27 percent increase in total crashes and 35 percent increase on fatal and injury crashes. The cross- sectional method also presented 25 percent increase on total crashes and 62 percent increase on fatal and injury crashes. It was seen that these increases were statistically significant.

Involvement in road traffic crashes as vehicle occupants is a leading cause of death and serious injury among children. The objective of this study was to investigate crash severity factors and child safety restraint use characteristics in order to identify effective countermeasures to increase children"s highway safety. Characteristics and percentages of restraint use among child passengers aged 4~13 years were examined using highway crash data from Kansas. The association between restraint use, injury severity and characteristics of children involved in crashes were investigated using OR (odds ratios) and a logistic regression model, which was used to identify risk factors. Results showed that children, who were unrestrained, were seated in the front seat, traveling with drunk drivers and on rural roads, and traveling during nighttime was more vulnerable to severe injury in the case of motor vehicle crashes. The most frequent contributing causes related to crashes involving children included driver"s inattention while driving, failure to yield right-of-way, driving too fast, wet roads and animals in the road. Based on identified critical factors, general countermeasure ideas to improve children"s traffic safety were suggested, including age-appropriate and size-appropriate seat belt restraints and having children seated in the rear seat. Parents and children must gain better education regarding these safety measures in order to increase child safety on the road.

We agree with the reader's comments that the availability of clinical features would benefit the clinical diagnosis greatly,and help the medical professionals to decide whether cytogenetic analysis is,or is not necessary for certain clinical features.However,the main aim of our study was to describe the frequency of various types of chromosomal abnormalities in sri Lankan children undergoing cytogenetic analysis since there was paucity of data in this field.
