The Landen transformation (a, b) 7→ ((a+b)/2, √ ab) preserves the value of an elliptic integral and its iteration produces the classical arithmeticgeometric mean AGM(a, b). We present analogous transformations for rational functions integrated over the whole real line.

costus speciosus (koen) j.e. sm. plant and its extracts are used for treatment of fever, snake bites, jaundice, and as a purgative, astringent and antibacterial agent. in the present study, an attempt has been made to evaluate in vitro antioxidant activity of different extracts of this plant by dpph radical scavenging activity, total antioxidant capacity, nitric oxide scavenging activity, ion c...

To the Editor, The Indian Medical Gazette. Sir,?In the January 1930 issue of the Gazette Dr. N. S. K. Iyer reports a case of aphonia following quinine administration. Whilst I was in charge of a dispensary at Kalva in the Kurnool district in 1902, there came to me a Mahomedan boy of 8 years old, asking for a dose of purgative. I gave him, I remember, a dose of Pulv. Jalapae Co., according to hi...

OBJECTIVE An adequate bowel cleansing is essential for a successful colonoscopy. Although purgative consumption is safe for the patient, there is little consensus on how the intestinal microbiota is affected by the procedure, especially regarding the potential long-term consequences. DESIGN 23 healthy subjects were randomised into two study groups consuming a bowel preparation (Moviprep), eit...

Multithreaded node architectures have been proposed for future multiprocessor systems. However, some open issues remain: can eecient multithreading support be provided in a multiprocessor machine such that it is capable of tolerating synchronization and communication latencies, with little intrusion on the performance of sequentially-executed code? Also, how much (quantitatively) does such non-...

Manna and Chaudhuri (Eur. J. Oper. Res. 171(2):557–566, 2006) presented a production-inventory system for deteriorating items with demand rate being a linearly ramp type function of time and production rate being proportional to the demand rate. The two models without shortages and with shortages were discussed. Both models were studied assuming that the time point at which the demand is stabil...
