Everyone is talking about oxygen concentrators now. Most of us had not heard of them before. Many know about distillers which extract water from air, yet very few realised that even oxygen can be extracted from air. So what is an Oxygen Concentrator and how do you choose the right one?

While we wait with bated breath for this Covid19 to pass, we can only forget the lessons it continues to teach us both at physical level and also at a deeper existential, philosophical level, at our own peril. In the latter half of this century when it is well behind us, and human race has the wisdom of hindsight, Covid19 may seem to be the one game-changer humankind desperately needed for course correction.
Retired Embankments are constructed at a distance from the river edge behind the existing embankment as a second line of defense. When Retired Embankments are constructed along both sides on high ground, sufficiently away from the river bank, more or less straight and little away from river channel to minimize the risk, they are sometimes called Flood Embankments. This is a very effective system and a neat solution to Flood Control where conventional methods of providing closer embankments are not effective.
India can look forward to join hands with Nepal in harnessing the hydropower potential and after fulfilling all Nepal’s internal needs avail surplus hydropower from Nepal to meet its own power demand besides augmentation of river flows in non-monsoon period and considerable flood control benefits in monsoon season.
China is the only neighbour, with whom India has geographically shared water resources, but there is no water sharing treaty so far. There seemed to be a great degree of timidity in this matter in the past, but it is changing now. The present government is now asserting itself as it holds national interest above everything else.

Occurrence of too many geological surprises, which were blamed for the big mishaps in the two mega Projects Punatsangchhu – I & II ,intrigues one to investigate if ‘ harping on the geological surprises’ was only a scapegoat for the lack of proper geological investigations done by the Consultants and inappropriate design of rock support measures done by the Designers, who were same for both the Projects.
The strata shows small scale, S- shape tight folds and broad warping of the beds at places, indicating that the rock strata has undergone the polyphase deformation in the past leading to development of numerous criss-cross structural discontinuities like joints, shears etc. of different orders. Five prominent and two random joint sets are recorded in the right bank. The foliation is very close to moderately spaced from 2cm to 60 cm and dips towards valley slightly in d/s direction; however rolling of dip is observed at places, there it dips into the hill due to folding and warping. The general topography and gentle natural slopes on the right bank of river are controlled by low and valley ward dipping foliation planes.
