目前在日本,存在大量工业垃圾,包括各种塑料制品,ASR(汽车破碎垃圾),含有毒PCB(多氯联苯)的110变压器和PVC(聚氯乙稀)制品等.而来自城市垃圾焚烧炉的废气含有大量能量.因此,在充分考虑环境、避免二垩英生成的同时,安全回收来自工业垃圾、城市和/或工业垃圾焚烧炉的资源和能量是个非常重要的课题,这也将对抑制CO2排放作出贡献.正确地阐明焚烧过程中二垩英的生成机理及详细研究含少量二垩英的焚烧废气在冷却过程中大量形成二垩英的临界温度是项很重要的工作.解决这个问题可有效实现资源和能量的回收.本报告介绍日本在二垩英排放方面目前采取的对策和存在的问题以及大阪大学为阻止二垩英生成所做的基础研究工作.

Anchor-wire technique for multiple plastic biliary stents to prevent stent dislocation

International Symposium on Global Environment and Steel Industry(ISES’03)

＜正＞At present in Japan, there are a large amount of industrial wastes which include many kind of plastic products, a great amount of ASR （Automobile Shredder Rubbish）, many used transformers containing toxic polychlorinated biphenyl （PCB）, and a large amount of poly vinyl chloride （PVC） products and so on. Furthermore, the exhaust gas from municipal waste incinerator has a great quantity of energy. Therefore, the safe recovery of resources and energy from industrial wastes and municipal and/or industrial waste incinerators is very important subjects with no dioxins/furans （Dioxins） formation in sufficient consideration of the environment and also will be able to contribute to the suppression of CO2 *** is very important assignments to exactly elucidate the mechanism of Dioxins formation in incineration processes and to more investigate the critical temperature at which Dioxins formation becomes remarkable in cooling processes of an exhaust gas having little Dioxin’s concentration. The recovery of resources and energy can be effectively realized when those assignments are solved This report introduces the present countermeasures and the remaining subjects in Japan for Dioxins emission and fundamental studies in Osaka University with the aim of no Dioxins formation.

In endoscopic placement of multiple plastic biliary stents (PBSs),we sometimes experience proximal dislocation of the first PBS at the time of subsequent PBS *** describe the case of a 79-year-old male with obstructive jaundice caused by cholangiocarcinoma who needed to receive multiple PBS placements for management of *** proximal dislocation of the first PBS was observed,we prevented the dislocation via our technique of using guidewire inserted from the distal end of the first PBS to the side hole as the *** could complete this technique only by inserting guidewire through the side hole of the first PBS during the process of releasing the first PBS and pulling out the guidewire and the inner *** did not matter whether the anchor-wire went towards the third portion of the duodenum or the duodenal *** we introduce this "anchor-wire technique",which is useful for the prevention of PBS proximal dislocation in placing multiple PBSs.
