To study the long-term trend of coupling between two regions, we have chosen a species that travels from one region to another. Nitric oxide is one such species which is produced in the thermosphere and is transported downwards. Evidences point out t

A high-silica zeolite KZ-1 with two different SiO 2 /Al 2 O 3 ratios has been synthesized hydrothermally. Its sorption behaviour suggests it to be a medium-pore zeolite with 10-membered ring pore openings. The acid form of the sample with SiO 2 /Al 2

Zeolite ZSM-35 with a ferrierite structure and having a silica:alumina ratio of 22.5 has been synthesized hydrothermally using pyrrolidine as the template. The acid form, HZSM-35, showed exceptionally high para selectivity in ethylbenzene disproporti

An M.F. radar (2.2 MHz) operating at Saskatoon, Canada (52°N, 107°W) has been used to produce continuous wind data (∼ 80–110km) from September 1978–April 1981. The 24-, 12-h tidal oscillations reveal regular summer-winter transitions; in part

The diurnal and seasonal variations of electron density observed by partial reflection technique at Park Site, Saskatoon (52°N) in the mesosphere have been examined. It is found that an asymmetry in the diurnal variation of electron density exists i

Electron density profiles measured, at Saskatoon (52°N, L =4.4) during and after magnetic disturbances have been examined. It is seen that there is an enhanced electron density during magnetic disturbances, the enhancement being different at differe
