Seabirds are good candidates as ecological indicators, especially in under-studied ecosystems since they provide insights into marine ecosystem processes and f.nctions at various trophic levels. Our review discusses salient points on the present status of.seabirds in the Bay of.Bengal Large Marine Ecosystem;despite overall low seabird numbers and biomass, this region harbors 9 species of.terns, one of.the most threatened bird group worldwide, which are known to breed in various marine habitats of.Andaman and Nicobar islands, in addition to the coastal areas of.mainland. f.rther, we elaborate on employing seabirds as potential indicators of.this ecosystem and how they outscore other taxa in this aspect. f.nally, we argue that it is essentially to f.ll the gaps in our knowledge about the BOBLME, mainly about the interplay between seabirds, climate change and f.sheries.

Journal of.Energy and Power Engineering 2014年第3期8卷 431-447页

f.r f.nland, carbon dioxide mineralisation was identif.ed as the only option f.r CCS （carbon capture and storage） application. Unf.rtunately it has not been embraced by the power sector. One interesting source-sink combination, however, is f.rmed by magnesium silicate resources at Vammala, located -85 km east of.the 565 MWe coal-f.red Meri-Pori Power Plant on the country＇s southwest coast. This paper assesses mineral sequestration of.Meri-Pori power plant CO2, using Vammala mineral resources and the mineralisation process under development at Abo Akademi University. That process implies Mg（OH）E production f.om magnesium silicate-based rock, f.llowed by gas/solid carbonation of.the Mg（OH）2 in a pressurised f.uidised bed. Reported are results on experimental work, i.e., Mg（OH）2 production, with rock f.om locations close to Meri-Pori. Results suggest a total CO2 f.xation capacity -50 Mt CO2 f.r the Vammala site, although production of.Mg（OH）2 f.om rock f.om the site is challenging. f.nally, as mineralisation could be directly applied to f.ue gases without CO2 pre-capture, we report f.om experimental work on carbonation of.Mg（OH）2 with CO2 and CO2-SO2-O2 gas mixtures. Results show that SO2 readily reacts with Mg（OH）2, providing an opportunity to simultaneously capture SO2 and CO2, which could make separate f.ue gas desulphurisation redundant.

在银币的生产过程中,硬币表面发蓝是非常普遍的现象。许多硬币收藏者用放大镜,甚至是显微镜去观察硬币发蓝。如果不满意硬币的外观,收藏者将退还硬币给造币厂。为了清除银币表面的发蓝,造币生产线必须被中断,以抛光或清洗压印的模具。... 详细信息

在银币的生产过程中,硬币表面发蓝是非常普遍的现象。许多硬币收藏者用放大镜,甚至是显微镜去观察硬币发蓝。如果不满意硬币的外观,收藏者将退还硬币给造币厂。为了清除银币表面的发蓝,造币生产线必须被中断,以抛光或清洗压印的模具。如果毛胚没有处于良好的准备状态,抛光一副冲模的时间就超过了压印硬币的时间。文中分析了硬币表面发蓝的原因,揭示了在模压过程中值得注意的摩擦学现象,并且提出了无需人工抛光冲模去除发蓝的方法,实现了银币的高效生产,清洗模具周期由冲压80次,提高到800次以上。

＜正＞ According to molecular data, carduelines （f.ingillidae） and estrildids （Passeridae） are two not directly related taxa. Both taxa crack and husk seeds bef.re swallowing the kernel. Although this poses similar f.nctional demands on the f.eding apparatus these two subf.milies show dif.erences in perf.rmance.

This paper reports on a new type of.high-f.equency mode-matched gyroscope with signif.cantly reduced dependencies on environmental stimuli such as temperature,vibration,and shock.A novel stress-isolation system is used to ef.ectively decouple an axis-symmetric bulk-acoustic wave(BAW)vibratory gyro f.om its substrate,minimizing the ef.ect that external sources of.error have on the of.set and scale f.ctor of.the ***-decoupled(SD)BAW gyros with a resonance f.equency of.4.3 MHz and Q values near 60000 were implemented using the high aspect ratio poly and single-crystal silicon(HARPSS)process to achieve ultra-narrow capacitive ***-level packaged sensors were interf.ced with a customized application-specif.c integrated circuit(ASIC)to achieve low variations in the of.set across temperature(±26°s^(−1) f.om−40 to 85℃),supreme random-vibration immunity(0.012°s^(−1) gRMS−1)and excellent shock *** a scale f.ctor of.800μV(°s^(−1))^(−1),the SD-BAW gyro system attains a large f.ll-scale range(±1250°s^(−1))with a non-linearity of.less than 0.07%.A measured angle-random walk(ARW)of.0.39°/√h and a bias instability of.10.5°h^(−1) are dominated by the thermal and f.icker noise of.the integrated circuit(IC),*** measurements using external electronics show bias-instability values as low as 3.5°h−1,which are limited by f.ed-through signals coupled f.om the drive loop to the sense channel,which can be f.rther reduced through proper re-routing of.the gyroscope pin-out conf.guration.
