Extraction of organochlorine pesticides in sediments using soxhlet,ultrasonic and accelerated solvent extraction techniques

The application of soxhlet, ultrasonic and accelerated solvent extraction techniques to the analysis of six organochlorine pesticides (α-HCH, β-HCH, γ-HCH, o, p'-DDT, p,p'-DDT and p, p'-DDE) in Taihu Lake sediment samples is described. It was found that the limits of quantification ranged from 0.002μgg-1 to 0.004μgg-1, and the recoveries of organochlorine pesticides with the three extraction techniques were acceptable (>80.7%). With a mass selective detector, better results were obtained by accelerated solvent extraction using hexane-acetone (1:1) as compared with soxhlet and ultrasonic extraction. It was shown that the accelerated solvent extraction was the optimum technique for the analysis of organochlorine pesticides in sediments. The general features of the three extraction techniques are also presented.

Postcrystallization thermal evolution history of Gangdese batholithic zone and its tectonic implication

Using cooling curves of K-feldspars obtained by using specific⁴⁰Ar/³⁹Ar stepe heating procedure and multiple diffusion domain modeling (MDD model), together with results of dating hornblends, biotite, and apatite, further work has been done to examine the characteristics of the postcrystallization thermal evolution history of Gangdese batholithic zone, to compare the starting times of rapid cooling events with the variation regularities of apatite fission track (FT) ages in the eastern and western parts of Gangdese batholithic zone, and to provide the evidence for mass transport and energy transfers in the lithosphere after the collision between Indian and Eurasian plates.

基于卫星高度计和漂流浮标数据间数学校验关系的黑潮流轴和流路主成分估计

由于卫星高度计数据分辨率高、观测范围广的特点,我们使用该数据开展了黑潮流的研究。在之前的研究中,卫星绝对地转流都被用于对黑潮流域的表层流场的时空变化特征进行研究,并采用了一些探测方法提取了黑潮流轴和流路。然而,海面绝对地转流是由绝对动力地形估计得到,应该被当做实际流场的地转分量,在实际应用中并不能代表真实流场。在本研究中,建立了气候态绝对地转流与网格平均的漂流浮标流场间的数学校验关系,以此对卫星绝对地转流场进行修正,即便这两种数据的性质存在些许偏差。因此,基于主成分探测法,修正后的卫星绝对地转流被用于探测黑潮流轴和流路。对比结果表明,由修正后的卫星地转流场探测得到的黑潮流轴和流路均要好于地转流和表层流估计结果。修正后的地转流有助于开展更加准确的黑潮流轴和流路的逐日探测。     

A culture-dependent survey of thermophilic bacteria from hot springs in Xiamen area in China

Microbes are believed to play important roles in ecosystem function in many environments. The hot springs of Xiamen Island are close to the Xiamen Sea, and may have some characteristics different from those of inland hot springs. Microbes living in the hot springs of Xiamen may have new characteristics. However, little is known about microbial communities of hot springs close to the Xiamen Sea. A cuhure-dependent survey of microbial population in the Xiamen hot springs was pcrformed by using an approach combining total cellular protein profile identification and 16S rRNA gene sequencing. A total of 328 isolates of bacteria were obtained from liquid and sediment samples from the Xiamen hot springs, including neutrophilie thermophilic bacteria and moderately thermophilic acidophiles. Neutrophilic thermophilic bacteria, which grow at a temperature range of 55-90℃ including Rhodothermus marinus (Strain 1) , Thermus thermophilus (Strain 2), Thermus thiopara (Strain 3) , Geobacillus stearothermophilus(Strain 4) , Geobacillus thermoleovorans (Strain 5) , and Pseudomonas pseudoal-caligenes (Strain 6), were recovered by 2216E plates. Moderately thermophilic acidophiles, which can grow at temperatures above 50℃ and a pH range of 1. 8-3.5 such as Alicyclobacillus acidoterrestris (Strain 8) , Sul-fobacillus acidophilus (Strain 9), and Sulfobacillus thermosulfidooxidans (Strain 10), were isolated on selective solid medium containing sulfur and Fe2+. Among these strains, Rhodothermus marinus, Thermus thermophilus and Geobacillus stearothermophilus are not only thermophilcs, but also halophiles. One bacterium strain (Strain 6) shared 99% nucleotide sequence homology with Pseudomonas pseudoalcaligenes on the 16S rRNA gene se-quence, but was quite different from Pseudomonas pseudoalcaligenes in biological characteristics, suggesting that it may represent a novel thermophilic species. Results indicated that various species of neutrophilic thermophiles and moderately thermophilic acidophiles were widely distributed in the Xiamen hot springs and that Rhodother-mus marinus and Thermus thermophilus dominated the cultivable microbial community.

CT对隐性骨折的诊断价值

目的：探讨ＣＴ对隐性骨折的诊断价值。方法：回顾性分析８４例隐性骨折患者,其中男６４例,女２０例,年龄７￣７３岁,平均４２．６岁。所有患者均行轴位或冠状位ＣＴ扫描。结果：扫描发现脊柱骨折２８例,髋臼骨折８例,胫骨平台骨折１１例,眶骨骨折１２例,颞骨骨折１３例。肩胛骨骨折１２例。结论：ＣＴ对隐性骨折的诊断具有极大价值,对于高度怀疑骨折而Ｘ线片未显示骨折征象的患者应进一步给予ＣＴ扫描检查。
