President Donald Trump gave orders to release water from Northern California's two largest reservoirs, Lake Oroville and Lake Shasta, which are nearly full, putting spillways into action and ...

‘Now, over 200 trees have been chopped inside the Rajshahi Textile Mills. In this way, the oxygen reservoirs of the city are being destroyed one after another on a daily basis, which is having a ...

“Though we carried out the material syntheses under high temperatures, the chemical-sensing measurements were done at extremely cold, or cryogenic, temperatures. This way prevented helium from ...

It is widely believed that Earth's atmosphere has been rich in oxygen for about 2.5 billion years due to a relatively rapid increase in microorganisms capable of performing photosynthesis.

The low oxygen level affects water chemistry in a way that generates a richer nutrient mix. That water, when stirred up to the top of the reservoir, allows for conditions that support algae blooms.

The Indian Space Research Organisation (commonly known as ISRO) has successfully conducted a hot test on the semi-cryogenic engine ... Uses liquid oxygen and kerosene, which is easier to store ...

When it happened, the late-January release of around 2.2 billion gallons from California reservoirs already seemed strange, ill-advised and abrupt. But a new report from the Washington Post ...

ISRO has been using environment-friendly and green propellants like Liquid Oxygen (LOX), Liquid Hydrogen (LH2) and LOX-kerosene-based propulsion systems. The cryogenic engine uses liquid oxygen and ...
