这里离最近的加油站有80多千米,到达任何一种基础设施都要划五天的船,我迈出独木舟,挥手告别伙伴们,进入了一个未知的世界。我带有一把折叠小刀、一张防雨布、一根六米多长的绳子、一根鱼竿、一本《圣经》、一个日记本、一个睡袋、几件衣服、一些水、一个苹果以及两条格兰诺拉燕麦棒。我突然意识到,在接下来的48小时里,仅有这些东西与我相伴了。

Journal of Iron and Steel Research International 2013年第1期20卷 71-78页

作者： M V Venkatesan N Murugan b.M Prasad A Manickavasagam Department of Mechanical Engineering Coimbatore Institute of TechnologyCoimbatore 641014TNIndia Integral Coach Factory Indian RailwaysChennai 600038TNIndia

The influence of flux cored arc welding （FCAW） process parameters such as welding current, travel speed, voltage and CO2 shielding gas flow rate on b.wing distortion of 409M ferritic stainless steel sheets of 2 mm in thickness was discussed. The b.wing distortions of the welded plates were measured using a simple device called profile tracer. An experimental regression equation was developed to predict the b.wing distortion and with this equation, it is easy to select optimized process parameters to achieve minimum b.wing distortion. It is revealed that the FCAW process parameters have significant influence on b.ad profile and the b.wing distortion.

Ob.ective To investigate protective effect of Coleus aromaticus leaf extract against naphthalene induced hepatotoxicity in rats. Methods Eighteen male rats were divided into three groups. Group I rats were treated as control. Group II rats were intraperitoneally administered with naphthalene （435 mg/kg ***） dissolved in corn oil once a day for a period of 30 days. Group III rats were treated with leaf extract （100 mg/kg ***） dissolved in 0.9% saline and naphthalene （435 mg/kg ***） dissolved in corn oil once a day for a period of 30 days. Results Significant protective effect was ob.erved against naphthalene induced liver damage, which appeared evident from the response levels of marker enzymes （aspartate transaminase, alanine transaminase, acid phosphatase, alkaline phosphatase and lactate dehydrogenase）. The b.ochemical components viz. triglycerides, free fatty acids, cholesterol acyl transferase, high-density lipoprotein, low-density lipoprotein, cholesterol and b.lirub.n were found to b. increased in liver and serum of naphthalene stressed rats when compared to control. Conclusion Treatment of naphthalene intoxicated rats with plant extract reversed these distorted parameters to near normal levels. Liver histology showed supportive evidence regarding the protective nature of plant extract against fatty changes induced b. naphthalene. The present study provides a scientific rationale for using C. aromaticus in the management of liver disorders.
