Local hydraulic gradient estimator analysis of long-term monitoring networks

Three measurements of head at unique locations form a three-point estimator of the local magnitude and orientation of the hydraulic gradient. The relative head measurement error (RHME) is defined here as the measurement error normalized by the head drop across the three-point estimator. Monte Carlo simulation results show that estimators with base to height ratios between 0.5 and 5.0 and that are large enough to keep the RHME below 0.05 create the most accurate gradient estimates and provide criteria for identifying good estimators. These criteria are applied to an example ground water monitoring network design problem in the Culebra dolomite near the Waste Isolation Pilot Plant repository to both analyze temporal changes and modify and expand the current monitoring network. Limiting the three-point estimators to those that meet the shape and RHME criteria reduces the number of possible estimators by >50% and leads to approximately 1 order of magnitude decrease in the average estimated magnitude of the gradient relative to using all estimators. Application of these criteria also reduces the variability in estimated gradient magnitude and orientation between the two time periods of measurements. Redundant wells in the network are identified by removing each existing well in turn and determining which removals yield the smallest decrease in the number of acceptable estimators. Optimal new well locations are identified by mapping the increase in total number of acceptable estimators for a single new well placed in the study domain.

说明预报技术和可预报性的一种图表

1.引言在过去25年中,数值天气预报模式以及观测资料和分析系统的改进已使天气尺度环流的业务预报取得了稳定的改进(Shuman,1978)。但是,众所周知,在运动的尺度不能分辨(或不能观测)情况下,由于初始误差的增长,最终将影响所有尺度的运动,使大气运动的可预报性有一个固有界限。即使“完美(Perfect)”的数值模式也是这样(完美模式是指一种不增加预报误差的模式)。     

脉冲星在银河系中空间分布的讨论(英文)

已发表的三个脉冲星星表共有384颗。采用这个样本并用一种经验的方法修正观测选择效应,获得脉冲星按银心距离的分布和银河系中可能存在的脉冲星总数。一个明显的峰值在离银心5—7KPC处。脉冲星的总数为(8.4±3.7)×10~4。采用束因子值为5和平均寿命为9×10~6年,得到诞生率为每15—38年产生一颗。     

冲断层、张性断层与花岗岩侵入作用关系的构造证据

本文提出了翁布里诺（Hombreiro）侵入体新的构造和岩石组构资料。翁布里诺侵入体是位于西班牙华力西构造带北部的一个同构造便位的花岗岩体。该岩体表现有两期塑性交形特征:早期变形与蒙多涅多（Mondonedo）推覆体的运动有关,此推覆体具有上盘向东的剪切指向;晚期变形则与比韦罗（Vivero）断层有关,此断层为一上盘向西运动的张性剪切带。这两期变形都始于高温近花岗岩固相线条件下,石英中保留有[c]-滑移组构可作证明。这一事实表明,在蒙多涅多推覆体上冲过程中,翁布里诺花岗岩发生侵位,在其定位过程中,张性断层不久即开始活动。本文提出,比韦罗断层的位置受地壳不稳定性所控制,而这种地壳不稳定性则由位于该断层下盘的许多侵入体的侵入作用所引起。     

Towards an operational use of space imagery for oil pollution monitoring in the Mediterranean basin: a demonstration in the Adriatic Sea

Studies of operational pollution carried out by European commission - Joint Research Centre in the Mediterranean Sea for the years 1999-2004 are briefly introduced. The specific analysis of the Adriatic Sea for the same period demonstrates that this area has been characterized by a relevant number of illegal discharges from ships. After setting the historical background of the project AESOP (aerial and satellite surveillance of operational pollution in the Adriatic Sea), the content, partners and aim of the project are presented. Finally, the results of the first phase of the AESOP project are presented. The results seem very encouraging. For the first time in the Adriatic, real time detection of oil spills in satellite images and an immediate verification by the Coast Guard has been undertaken. An exploratory activity has also been carried out in collaboration with the University of Ljubljana to use automatic information system (AIS) to identify the ships detected in the satellite images.     

澳大利亚的第三纪及第三纪—第四纪过渡期(英文)

第三纪的板块运动驱动着澳大利亚的气候和植被进行演化。广布的湿润森林区是澳大利亚老第三纪的特征。一直到始新世 ,生物多样性都在不断地提高。毫无疑问 ,这是澳大利亚由高南纬区向北部中纬区运移的结果。从始新世到上新世 ,澳大利亚的气候总体上要比现在湿润 ,但降水量季节性变化的增强推动了中新世以后硬叶植物和旱生植物的发展。上新世晚期似乎与第四纪一样 ,都出现过周期性干旱。这种干旱与冰期条件有关 ,至少由南澳大利亚晚第四纪的记录可以认识到这一点 ,澳大利亚的这段历史与东亚的气候变迁是同步发生的。在东亚 ,印—澳板块的运动致使青藏高原抬升 ,从而引发了区内乃至全球气候的巨变。穿越赤道区的季风和信风的环流格局 ,致使新第三纪和第四纪中国与澳大利亚的气候系统的相关性更强。     

A pilot survey on antimicrobial activity and diversity of soil-derived actinobacteria from different depths in Gudzhirganskoe saline lake in Eastern Siberia

To explore pharmaceutical actinobacteria from salty environments in Siberia, 8 soil samples were collected from different depths of Gudzhirganskoe saline lake, the Republic of Buryatia, Russia.Totally, 635 actinobacterial strains affiliated with 21 genera in 12 families of 7 orders were obtained by culture-dependent approaches. The predominant genus was Streptomyces(74.5%), followed by Microbacterium(4.9%), Agromyces(3.5%), Nocardiopsis(3.0%), and Kitasatospora(2.5%). Seven strains showed relati...
