A juvenile coelurosaurian theropod from China indicates arboreal habits

Here we report an unequivocal arboreal coelurosaur, Epidendrosaurus ningchengensis gen. et sp. nov. This juvenile coelurosaur's third manual digit is extremely elongated, distinctively different from that of other known dinosaurs and birds. It represents certainly a type of adaptation previously unreported from the Mesozoic although the exact function of the third manual digit is unclear. The relatively long forelimb, penultimate phalanx of manual digit II, and pedal penultimate phalanges, are interpreted as evidence for the arboreal habit of Epidendrosaurus. Because Epidendrosaurus is more similar to advanced birds in some arboreal features than to Archaeopteryx, we suggest that the initial appearance of tree-adaptation in theropods was probably not directly related to flight but to other functions, such as seeking food or escaping from predators.

Removal of copper from a copper sulphate solution using an ultrasonic-electrolysis process

The application of ultrasonic-electrolysis process for the removal of copper is studied.In the ultrasonic field cavitation acts as jets and agitates the solution and breaks the barrier layer between the cathode surface and the bulk of the solution.Thus increases metal deposition on the cathode surface.The results show that an ultrasonic field is successful for the removal of low copper concentrations in solution.     

Determination and discussion hydraulic retention time in membrane bioreactor system

Based on the microorganism kinetic model, the formula for computing hydraulic retention time in a membrane bioreactor system (MBR) is derived. With considering HRT as an evaluation index a combinational approach was used to discuss factors which have an effect on MBR. As a result, the influencing factors were listed in order from strength to weakness as: maximum specific removal rate K, saturation constant Ks, maintenance coefficient m, maximum specific growth rate ,ua and observed yield coefficient Yobs. Moreover, the formula was simplified, whose parameters were experimentally determined in petrochemical wastewater treatment. The simplified formula is θ= 1.1( 1/β -1)(Kｓ S)/KXo , for oetroehemical wastewater treatment K and Ko eaualed 0.185 and 154.2, resoectively.

湖泊、水库水的强化混凝除藻的试验研究

就高锰酸钾复合药剂强化混凝对湖泊、水库水中藻类的去除进行了研究，试验表明：投加一定量的高锰酸钾复合药剂可显著提高水中藻类的去除率。将经与预氯化、预投加高锰酸钾除藻工艺进行比较，表明高锰 酸钾复合药剂强化混凝除藻效率明显优于传统预氯化、预投加高锰酸钾除藻工艺。     

印尼8.7级和8.5级强震后江苏体应变同震效应分析

2004年12月26日和2005年3月29日在印尼苏门答腊北部分别发生8.7级和8.5级强烈地震后,对江苏地区前兆体应变资料进行分析发现,在这两次地震的震后都记录到了显著的异常,且异常的表现形式各不相同。本文列出这些异常并浅析,以期对进一步深入研究印尼大震对我国未来地震趋势的影响有所帮助。     

抚顺市空气可吸入颗粒物特征的研究

于2002年1～7月份在抚顺市区四个点位采集了环境空气中的可吸入颗粒物样品，经分析后获得了可吸入颗粒物组分的时间分布和空间分布特征，即采暖期PM10样品中有机碳（OC）、元素碳（EC）的绝对含量和相对含量均高于非采暖期，工业区PM10样品中的Fe、Zn、Pb的绝对含量和相对含量均明显高于其它点位，反映了其工业区的特点。     

垃圾焚烧飞灰物理化学性质的实验研究

应用激光粒度粒形分析仪、灰熔融性测定仪、原子吸收光谱仪和XRD等仪器手段对国内2种垃圾焚烧飞灰的密度、颗粒特性、熔点、成分和晶相结构等物理化学性质进行了详细的研究。研究发现，2种灰样颗粒直径的数量积分分布非常接近，其中基本没有超过40／μm的颗粒。由于垃圾焚烧飞灰在化学成分上存在的差异导致了其熔点有很大的不同。此外，XRD结果显示不同来源的飞灰其晶相结构存在较大的差别，这可能与垃圾的来源和焚烧工艺以及烟气处理方法有关。实验结果为飞灰无害化低温烧结工艺的选择和运行参数的制定提供了依据。
