| 1 | Effect of Welding Processes and Consumables on Tensile and Impact Properties of High Strength Quenched and Tempered Steel Joints显示文摘Quenched and tempered steels are prone to hydrogen induced cracking in the heat affected zone after welding.The use of austenitic stainless steel consumables to weld the above steel was the only available remedy because of higher solubility for hydrogen in austenitic phase.In this investigation,an attempt was made to determine a suitable consumable to replace expensive austenitic consumables.Two different consumables,namely,austenitic stainless steel and low hydrogen ferritic steel,were used to fabricate the joints by shielded metal arc welding(SMAW)and flux cored arc welding(FCAW)processes.The joints fabricated by using low hydrogen ferritic steel consumables showed superior transverse tensile properties,whereas joints fabricated by using austenitic stainless steel consumables exhibited better impact toughness,irrespective of the welding process used.The SMAW joints exhibited superior mechanical and impact properties,irrespective of the consumables used,than their FCAW counterparts. | G Magudeeswaran V Balasubramanian G Madhusudhan Reddy T S Balasubramanian | 2008 | Journal of Iron and Steel Research(International)2008，15，6： | 16 |
| 2 | Antimicrobial potential of selected brown seaweeds from Vedalai coastal waters,Gulf of Mannar显示文摘Objective:To evaluate the antimicrobial activity of Turbinaria conoides(T.conoides).Padina gymnospora(P.gymnospora) and Sargassum tenerrimum against human bacterial and fungal pathogens.Methods:The antimicrobial activities of the extracts against various organisms were tested by using disc diffusion method.Results:The methanol extract showed the better result than the other extracts.Whereas,the strong antibacterial inhibition was noted in methanol extracts of P.gymnospora against Bacillus subtilus(26.33±1.86) and the mild inhibition of ethanol extracts from T.conoides against Klebsiella pneumoniae(2.33±0.51).Acetone extraction of P. gymnospora had strong antifungal inhibition against Cryptococcus neoformans(23.00±1.78), and acetone extract of T.conoides had mild inhibition against Aspergillus niger(3.00±0.89). Conclusions:The seven different solvent extracts of seaweeds used in the present study have shown significant bacterial action.Further,a detailed study on the principle compound in the seaweeds which is responsible for antimicrobial activity is still needed and it can be achieved by using advanced separation techniques. | Manivannan K Karthikai devi G Anantharaman P Balasubramanian T | 2011 | Asian Pacific Journal of Tropical Biomedicine2011，1，2： | 9 |
| 3 | Hepatoprotective activity of brown alga Padina boergesenii against CCl_4 induced oxidative damage in Wistar rats显示文摘Objective:To investigate the protective effects of brown alga Padina boergesenii(P.boergeseii) against carbon tetrachloride(CCl4) induced oxidative damage and liver fibrosis in rats.Methods: To assess the hepatic damage liver weight,the activities of TBARS level,glutathione,SOD,CAT and GPx in circulation and liver.Results:The group of rats induced with CCl4 alone(2 mL/kg body weight),showed noticeable increase in the liver weight and TBARS level.Followed by, the level of antioxidant enzymes glutathione peroxidase,Superoxide dismutase and catalase was also significantly(P<0.01) diminished.Where as,the rats pretreated with P.boergesenii(150 mg/ kg body weight) modulated the CCl4 induced liver fibrosis.The level of antioxidant enzymes and lipid peroxidation products was found to be significandy(P<0.01) attenuated to near normal level, when compared with rats induced with CCL,alone.In order to assess the role of carotenoids in the relevant activity,total carotenoid content of the extract was analysed and found to be 0.59 mg/g fresh weight(FW).Further,the histopathogical studies provide a supportive evidence for this study to show the protective nature of P.boergesenii.Conclusions:The protective role of brown alga P.boergesenii extract has confirmed its potential activity through its antioxidant sparing actions against CCl4 induced free radical damage.However,the possible mechanism of hepatoprotection is rather speculative at this stage and investigations are underway to isolate and characterize the bioactive compounds from P.boergesenii. | Rajamani Karthikeyan ST Somasundaram T Manivasagam T Balasubramanian P Anantharaman | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，9： | 6 |
