Two species of giant water bugs Lethocerus were found in the Gangetic plains of northern India and Nepal. Lethocerus indicus is widespread, whereas a single record of Lethocerus patruelis confirms the eastern distribution range in Bihar. Four instars

The order Odonata is one of the most widely studied groups among insects from the oriental region. They colonize in both stagnant and running water bodies of wide water quality. Hitherto, the existing literature on the Odonata contained numerous publ

Wigglers and undulators produce intense synchrotron radiation, used for dedicated experiments or to control beam dimensions. To obtain tolerance criteria for wiggler and undulator field errors, this paper presents a treatment which takes into account

In May 93 the operation of DORIS for high energy physics was discontinued and the ring became a dedicated source for synchrotron radiation operated at 4.5 GeV. Meanwhile a multibunch feedback system to control beam instabilities had been installed an

During the last year the e-e+-storage ring DORIS was changed from a 2 × 3,5 GeV double ring with 2 × 480 bunches circulating to a single ring single bunch machine with a maximum energy of 2 × 5.1 GeV. The modifications in the magnet structure and
