Anaerobic Rem.val of Trace Organic Contam.nants in Sewage Sludge: 15 Years of Experience

Pedosphere 2012年第4期22卷 508-517页

Trace organic contam.nants (TOCs) correspond to a broad range of m.lecules generated either directly or indirectly by hum.n activity. Even though TOCs are found at low concentrations in the environm.nt, they often accum.late by biom.gnification and bioaccum.lation into biological organism. and cause irreversible dam.ges in biological system. through direct or indirect toxic effects such as endocrine disruption and tum.ur initiation. This m.nuscript presents the m.in findings of over fifteen years of research focusing on biological rem.val of various TOCs found in sewage sludge from.urban treatm.nt plants. A special focus of the research was m.de on m.crobial processes in com.lex anaerobic ecosystem.. Four fam.lies of com.ounds m.stly retrieved in urban plants were studied: the polycyclic arom.tic hydrocarbons (PAHs), the polychlorobiphenyls (PCBs), the phthalic acid esters (PAEs), and the nonylphenol ethoxylates (NPEs). It was observed that the m.crobial capability for rem.ving low am.unts of TOCs required a long adaptation tim. and was often lim.ted by the bioavailability of these com.ounds. In fact, the overall biodegradation resulted from.the num.rous interactions existing between the m.trix (organic m.tter) and the m.crobial ecosystem. according to the physico-chem.cal sorption properties of these com.ounds. m.chanistic aspects were also tackled in depth and specific m.dels were developed for better understanding the network of interactions between TOCs, m.croorganism., and organic m.tter. These findings could be extrapolated to other ecosystem. such as soils and sedim.nts. Finally, it was shown that m.crobial com.tabolism.was essential for TOC rem.val, and the concept of bioavailability was not only dependent on the nature, the level, and the sorption properties of TOCs but was also strongly dependent on the nature and the concentration of the sludge organic m.tter. Specific param.ters were proposed for better evaluating the fate of TOCs in m.crobial anaerobic

World Journal of Gastrointestinal Endoscopy 2015年第16期7卷 1222-1229页

AIm.To determ.ne the optim.l generator settings for endobiliary radiofrequency ablation. m.THODS:Endobiliary radiofrequency ablation was perform.d in live swine on the am.ulla of Vater,the com.on bile duct and in the hepatic parenchym.. Radiofrequency ablation tim.,"effect",and power were allowed to vary. The anim.ls were sacrificed two hours after the procedure. Histopathological assessm.nt of the depth of the therm.l lesions was perform.d. RESULTS:Twenty-five radiofrequency bursts were applied in three swine. In the am.ulla of Vater(n = 3),necrosis of the duodenal wall was observed starting with an effect set at 8,power output set at 10 W,and a 30 s shot duration,whereas superficial m.cosal dam.ge of up to 350 μm.in depth was recorded for an effect set at 8,power output set at 6 W and a 30 s shot duration. In the com.on bile duct(n = 4),a 1070 μm.safe and efficient ablation was obtained for an effect set at 8,a power output of 8 W,and an ablation tim. of 30 s. Within the hepatic parenchym.(n = 18),the depth of tissue dam.ge varied from.1620 μm.effect = 8,power = 10 W,ablation tim. = 15 s) to 4480 μm.effect = 8,power = 8 W,ablation tim. = 90 s). CONCLUSION:The duration of the catheter application appeared to be the m.st im.ortant param.ter influencing the depth of the therm.l injury during endobiliary radiofrequency ablation. In healthy swine,the currently recom.ended settings of the generator m.y induce severe,supratherapeutic tissue dam.ge in the biliary tree,especially in the high-risk area of the am.ulla of Vater.

本文对位于捷克与德国边境受到严重污染的Krusne Hory山区1972～1989年间森林破坏的范围、速率及其空间特性进行了研究。利用卫星遥感数据与数字地形数据相结合,对森林破坏进行评估。结果表明:有50%的针叶林在这一时期消失;受影响地区位于海拔600与1000m.坡向朝南和东南的坡地;位于SO_2和NO_x的强污染点源下风向地区的森林受到严重破坏。森林破坏与距离点源的远近间关系不明确。1989年依据针叶脱落,应用卫星遥感对森林损害的估算结果表明:现存的308km.2针叶林中,被划分为受轻度、中度及重度损害的森林分别为79%、17%及4%。

In this paper we describe the potential of the enhanced X-ray Tim.ng and Polarim.try(eXTP) m.ssion for studies related to accretion flows in the strong field gravity regim. around both stellar-m.ss and superm.ssive black-holes. eXTP has the unique capability of using advanced "spectral-tim.ng-polarim.try" techniques to analyze the rapid variations with three orthogonal diagnostics of the flow and its geom.try, yielding unprecedented insight into the inner accreting regions, the effects of strong field gravity on the m.terial within them.and the powerful outflows which are driven by the accretion process.

Therm.l Characteristics of Gel Grown Lanthanum.Heptam.lybdate crystals

引用

Journal of m.terials Science & Technology 1995年第6期11卷 455-459页

作者： Sushm. Bhat and P.N.Kotru(Dept. of Physics, Uuiversity of Jam.u, Jam.u -180 001, India) m.L.Koul(Dept. of Chem.stry ,Uuiversity of Jam.u, Jam.u, India) Univ of Jam.u Jammu India

Therm.l characteristics of Ianthanum.heptam.lybdate crystals grown by gel technique, em.loying therm.analytical techniques, viz. TG, DTA and DSC, are reported. It is established that the rare-earth lanthanum.heptam.lybdate crystals are associated with thirty water m.lecules;the com.osition being La2m.7O24.3OH2O. It is shown that all the thirty water m.lecules associated with lanthanum.heptam.lybdate crystal are lost during its decom.osition, leading to its anhydrous form. Results obtained on application of TG based m.dels, viz. Horowitz-m.tzger,Coats-Redfern and Piloyan-Novikova and of DSC based m.thods viz. Roger-m.rris-Sm.th and barret, regarding solid state reaction kinetics are also reported. The random.nucleation m.del is shown to be the one that is relevant to the decom.osition of lanthanum.heptam.lybdate. The kinetic param.ters, *** order of reaction. frquency factor, energy of activation and entropy using above m.ntioned m.dels are com.uted and shown to bear reasonably good agreem.nt
