    Breeding biology of the green turtle, Chelonia mydas (Reptilia: Cheloniidae), on Wan-An Island, PengHu archipelago. II. Nest site selection (1999)

    Notes: Abstract Nest site selection of the green turtles on Wan-An Island in the summer of 1996 was determined. Turtles (Chelonia mydas) laid on average one clutch for every three emergences. Even though the total track length was 115 m on average, individual lengths varied considerably depending on the nesting beach where the turtles emerged. Limited accessibility, i.e. adequate distance from the nearest village and a well-protected environment, make beaches A and D suitable nesting beaches for green turtles on Wan-An Island. Both total track and nesting track apexes were found clustered in the interface zone, and turtles preferred to reach the vegetation zone once they emerged from the sea. It is suggested that the turtles on Wan-An Island exhibit nest site selection behavior. Based on these results and the high nest site fidelity to their first nesting beach, conservation recommendations are proposed to the county and central governments for the preservation of nesting beaches in their natural state, by prohibiting illegal sand mining and properly controlling turtle watch groups on Wan-An Island.

    Notes: In this paper the Li+, Sb3+-doped SiO2-TiO2 thin films, which were heat-treated with an appliedelectric field, were prepared by sol-gel dip coating. The crystallization of the thin films in the electric fieldheating-treatment was studied by X-ray diffraction (XRD) and atomic force microscope (AFM). Thephoto-catalytic activity of SiO2-TiO2 films was studied under the condition of an electric fieldheating-treatment and mixing with some additive such as Li+ and Sb3+. Finally, studies on photo-catalyticdegradation showed that the Li+, Sb3+-doped SiO2-TiO2 films on the quartz glass, of high photo-catalyticactivity, were successfully obtained in the electric field heating-treatment

    Fatigue Behaviors of a NiCrAlYSi Coated Directionally Solidified Nickel Base Superalloy (2008)
    s.l. ; Stafa-Zurich, Switzerland

    Notes: The fatigue behaviors of a directionally solidified (DS) nickel base superalloy, coated witha MCrAlY coating (NiCrAlYSi) were studied. Two kinds of tests were performed. One kind of testsare low cycle fatigue (LCF) test under strain control at different temperatures, another kind of testsare stress controlled LCF test with SEM-servo hydraulic testing machine for in situ crackingobservation. The results show that the effect of coating on LCF life of coating/substrate system wasrather different according to different strain levels and temperatures. The coating has no or less effecton LCF life under high strain range and the LCF life is governed by fatigue behavior of substrate inspite of the difference of temperature. However, when strain range is smaller, crack initiation andpropagation are observably affected by temperature, which leads to a shorter LCF life ofcoating/substrate system at 500ºC and a longer LCF life at 760ºC or 980ºC. This means the failure ofcoating/substrate system is dominated by the cracking of surface coating under low strain range. Thebrittleness at 500ºC lower than DBTT results in rapid stage II crack propagation. The crack initiationfrom coating surface was in situ observed at room temperature and 700 ºC and it was found thatcracks usually initiated from the surface roughness of coating and then propagate to failure. Thebrittleness and surface roughness are the basic acceptable causes leading to the early damage of acoating/substrate system

    Notes: Abstract  The effects of arbuscular mycorrhizal fungi alkaline phosphatase (ALP) activities on the drought-resistance of Hippophae rhamnoides under water stress have been studied using histochemical techniques. The result shows in the mycorrhizae that total hyphae and functional hyphae form the base for the active hyphae, and amounts follow the order total hyphae〉functional hyphae〉active hyphae. Active hyphae play an important role in the biomass accumulation of the hosts; the hyphae with phosphatase activity (ALP) have a positive and strong effect on H. rhamnoides growth and its drought-resistance, and the rise of ALP is related to an increase in the fresh weight of the host trees, and a reduction of wilting. The direct participation of ALP in the P nutrient exchange host trees can improve the nutrient and water conditions, and raise their drought-resistance.

    An Effective Statistical Approach for Comparative Risk Assessment (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Risk analysis 16 (1996), S. 0

    ISSN: 1539-6924

    Notes: Comparative risk assessment is an evaluation process designed to rank environmental problems based on the severity of potential hazards. The purpose of this paper is to provide an effective statistical approach to analyze perceived environmental risks. Environmental problems, evaluative criteria, and other potential moderator variables need to be determined first, and then the risk perception data collected. Repeated measures analysis is used to first test for interactions between environmental problems and potential moderator variables. If there are no significant interactions, then the risk difference among environmental problems is tested unconditionally; otherwise the risk difference is tested conditionally. Cluster analysis for environmental problems is performed only when the risk difference is significant. The clustering results can be objectively determined by using the simultaneous T2 confidence intervals. Risk-based priority setting is made according to the clusters obtained. To illustrate this approach, an empirical study of comparative socioeconomic risks in Taiwan was conducted. Socioeconomic impacts areas including social security, quality of life, production cost, investment willingness, and economic resources are used as evaluative criteria. Results indicate that selected impact areas do affect relative risk differences among 24 environmental problems, and the difference is significant for each area. Therefore, cluster analysis is conducted separately for each impact area. Risk-based priority settings for clusters of environmental problems are reported.

    Notes: The isothermal low cycle fatigue (LCF) behaviors of a directionally solidified (DS) nickelbase superalloy, coated with a NiCrAlYSi coating were studied. The study concerned NiCrAlYSicoating formed by an arc-discharged physical vapor deposition (PVD) process for protection againsthigh-temperature corrosion and oxidation of gas turbine blades. The effect of protective coating onLCF life of coating/substrate system was investigated at high temperatures and compared withuncoated alloy. The test results show that coating has no or less effect on LCF life under high strainrange and the LCF life is governed by the fatigue behavior of substrate at different temperatures.However, when strain range is smaller, crack initiation and propagation are observably affected bytemperature, which leads to a shorter LCF life of coating/substrate system at 500ºC and a longer LCFlife at 760ºC or 980ºC

    Notes: Tensile creep tests were conducted at 980°C under a constant stress on a single crystalnickel base superalloy. Some tests were interrupted at different stages during the creep process. Thestrain-time curves indicated that this alloy exhibited conventional primary, steady-state and tertiarystages at this temperature. The transmission electron microscope (TEM) observations of foils takenfrom the gauge sections of specimens were made to interpret the microstructural evolution thatoccurred during the creep process. It was found that the γ′ particles were rafted in the directionperpendicular to the applied stress. The acceleration of the creep rate was related to the change of thedislocation density

    Notes: In this work, the self-assembled monolayers of γ-aminopropyltrimethoxysilane andoctadecyltrichlorosilane were prepared on titanium films, radiated and solidified by ultravioletradiation/ozone photochemical process. The characterization and friction properties of titanium film,APS SAMs, OTS SAMs and the radiated APS SAMs, OTS SAMs were explored by atomic forcemicroscopy and friction force microscopy. The effects of functional groups, sliding velocity, load andultraviolet radiation/ozone photochemical process on friction properties of SAMs were analyzed. Theexperimental results show that the titanium film coated with SAMs, especially under ultravioletradiation/ozone, is exhibited with a good friction property. The friction property of APS SAMs isbetter than OTS SAMs under or no ultraviolet radiation/ozone. The friction force increases with theincreasing of sliding velocity and decreases with the increasing of load

    Notes: Cavitaion erosion behavior of cast iron in water and in mixed solution of 50% H2O+50%C2H6O2 with different temperature and distance between two samples have been studied by meansof a ultrasonic vibrator. The mass loss of the samples at different time is recorded.The surfacestructure of the oxidation films on the surface of cast iron was analyzed by X-ray diffractionapparatus. The experimental results show that mass loss of the upper sample is more than that of thelower sample. The maximum of mass loss occurred when the distance between the samples is about1.0mm. Oxidation films form on the surface of the cast iron in pure water and cannot form on thesurface of cast iron in mixed solution. The XRD results show that the oxidation film mainly consistsof Fe2O3 phase at 50°C, Fe3O4 phase at 80°C. The mass loss at 50°C is less than that at 80°C.Oxidation film of Fe2O3 phase has some advantages to decelerate the cavitation erosion. Mass lossof the sample of cast iron in mixed solution is less than that in pure water at 80°C. Thisphenomenon indicates that formation of the oxidation films plays a more important role incavitation erosion to reduce or increase mass loss of the cast iron samples
