Sir,?I have read Dr. K. P. Kundu's article on 'Prawns as a possible vector of V. cholerce', published in the October 1938 issue of your Gazette, with keen interest. Heiberg (1935, 1936) as a rejoiner to the publication by Gardner and Venkatraman (1935) showed that the vibrios could be grouped into 6 by fermentation reaction of three sugars, mamose saccharose and arabinose, as Gardner and Venkat...

In most of the studies concerning nonlinear wave equations Korteweg-de Vries type, authors focus on waves elevation. Such have general form ~$u_{\text{u}}(x,t)=A f(x-vt)$, where ~$A>0$. this communication we show that if ~$u_{\text{up}}(x,t)=A f(x-vt)$ is solution a given equation, then $u_{\text{down}}(x,t)=-A is, an inverted same but with changed sign parameter ~$\alpha$. This property common...
