Solving Oxygen shortage by converting Nitrogen Generator into Oxygen Generator
Why in News?
- The Indian Institute of Technology (IIT) Bombay has come up with a creative and ingenious solution to addressing the shortage of medical oxygen for the treatment of COVID-19 patients in the country.
- The pilot project which has been tested successfully relies on a simple technological hack: conversion of PSA (Pressure Swing Adsorption) Nitrogen Unit to PSA Oxygen Unit!
- Oxygen production could be achieved at 3.5 atm pressure, with a purity level of 93% – 96 %. This gaseous oxygen can be utilised for COVID-related needs across existing hospitals and upcoming COVID-19 specific facilities by providing a continuous supply of oxygen.
How can the nitrogen unit be converted into an oxygen unit?
- It has been done by fine-tuning the existing Nitrogen Plant setup and changing the molecular sieves from Carbon to Zeolite.
- Such nitrogen plants, which take air from the atmosphere as raw material, are available in various industrial plants across India.
- Therefore, each of them could potentially be converted into an oxygen generator.
- The pilot project is a collaborative effort between IIT Bombay, Tata Consulting Engineers and Spantech Engineers, Mumbai, who deal with PSA Nitrogen & Oxygen plant production.

China launches key module of space station
Why in News?
- China launched an unmanned module containing what will become living quarters for three crew on a permanent space station that it plans to complete by the end of 2022.
- The module, named “Tianhe”, or “Harmony of the Heavens”, was launched on the Long March 5B, China’s largest carrier rocket, from the Wenchang Space Launch Centre on the southern island of Hainan.
- Tianhe is one of three main components of what would be China’s first self-developed space station, rivalling the only other station in service – the International Space Station (ISS).
- The ISS is backed by the United States, Russia, Europe, Japan and Canada. China was barred from participating by the United States.
- Tianhe forms the main living quarters for three crew members in the Chinese space station, which will have a life span of at least 10 years.
- The Tianhe launch was the first of 11 missions needed to complete the space station, which will orbit Earth at an altitude of 340 to 450 km (211-280 miles).
- In the later missions, China will launch the two other core modules, four manned spacecraft and four cargo spacecraft.
- Work on the space station programme began a decade ago with the launch of a space lab Tiangong-1 in 2011, and later, Tiangong-2 in 2016.
- China has prioritised space exploration in recent years, with the aim of becoming a major space power by 2030. By 2045, it hopes to establish a programme operating thousands of space flights a year and carrying tens of thousands of tonnes of cargo and passengers.

Mono Pile Technology in Coastal Road
Why in News?
- The Brihanmumbai Municipal Corporation (BMC) has decided to introduce mono pile technology, for the first time in the country, in the under-construction Coastal Road that connects south Mumbai to western suburbs.
- Generally, any bridge on a sea or river is built using group pile technology. But in mono pile technology, one single pile is used instead of four piles for supporting one pillar.
- This will save the space to construct the pillars. The number of piles has come down to 176 from 704 due to the introduction of this new technology. It is also environment friendly.

Predicting success of vaccine without a big trial
- Moderna’s vaccine provides protection against Covid-19 by triggering the production of antibodies against a key viral protein, a study in monkeys suggests. The insight — if confirmed in humans — could speed the development of next-generation vaccines.
- Vaccines can trigger diverse immune responses, including the manufacture of antibody molecules that bind and block infectious viruses, and the activation of T cells that kill virus-infected cells.
- By identifying the immune responses that can predict a vaccine’s success, scientists could more easily judge candidate vaccines.
- The vaccinated animals that had the lowest levels of viral genetic material in their noses and lungs also had the highest levels of antibodies that recognise the viral spike protein, the molecule that the Moderna vaccine encodes. Levels of other immune markers did not correlate as strongly with the vaccine’s protective effects.
- In a one-sentence summary of their findings, the researchers said “mRNA-1273 vaccine-induced antibody responses are a mechanistic correlate of protection against SARS-CoV-2 infection in NHP”.
- MRNA-1273 is the technical name for the vaccine developed by Moderna. NHP stands for ‘non-human primates’, i.e. monkeys.
- A parallel study now under way will compare immune markers in people who were protected by jabs, including the Moderna one, with markers in people who were infected despite receiving a vaccine.
- Identifying these ‘correlates of protection’ will help researchers to assess existing and future vaccines without running costly, large-scale clinical trials.

New SEBI rule for fund manager compensation
- The Securities and Exchange Board of India (SEBI) has said that a minimum 20% of the compensation of mutual fund managers and other key personnel in an asset management company (AMC) should be in the form of units of the mutual fund schemes they manage.
- Key personnel here refers to the likes of chief executive officer, chief investment officer, research head and their direct reportees.
What’s new in this circular? Isn’t pay linked to performance?
- The compensation of fund managers — at least the variable pay component — is linked to performance.
- What SEBI has done here is crystallise the rules and extend it beyond fund managers to so-called key employees.
- Moreover, SEBI has specified the rules of allocation of this 20% by saying that is should be proportional to the assets under management of the schemes in which an employee has a role or oversight.
- For example, a CEO who has overall oversight will have 20% of her compensation spread across all the schemes.
- On the other hand, a fund manager who manages only one fund will have at least 50% of this type of compensation in the scheme she manages and the remaining in other schemes of the mutual fund that are riskier.
- The regulator has also specified that these units offered by way of compensation are locked-in for three years.
How will this help retail investors?
- This move by SEBI will boost the transparency of fund manager compensation.
- It helps build accountability. It ensures that fund houses actually link the pay of fund managers to performance and go beyond lip service.
- Besides, since a whole lot of employees’ compensation is linked to how well a mutual fund is doing, it could encourage whistleblowing if wrongdoing is happening.
- It will give a lot of psychological comfort to investors that their fund manager has skin in the game.

World will lose 10% of glacier ice even if it hits climate targets
- A tenth of the world’s mountain glacier ice will have melted by the middle of this century even if humanity meets the goals of the Paris climate agreement.
- The loss is equivalent to more than 13,200 cubic kilometres of water – enough to fill Lake Superior, or more than 10m Wembley Stadiums – with knock-on effects on highly populated river deltas, wildlife habitats and sea levels.
- In some particularly hard-hit areas, including central Europe, North America and low latitudes, glacier mass is expected to decline by more than half.
- The overwhelming bulk of this melt-off, which does not include Greenland or Antarctica, is unavoidable because it has been locked in by the global heating caused by humans in recent years.
- The actions governments take today – including the recent announcements of more ambitious emissions-cutting goals by the US, the UK and others – can make a big difference to the landscape in the second half of this century.

Speed at which world’s glaciers are melting has doubled in 20 years
- The melting of the world’s glaciers has nearly doubled in speed over the past 20 years and contributes more to sea-level rise than either the Greenland or Antarctic ice sheets, according to the most comprehensive global study of ice rivers ever undertaken.
- Scientists say human-driven global heating is behind the accelerating loss of high-altitude and high-latitude glaciers, which will affect coastal regions across the planet and create boom-and-bust flows of meltwater for the hundreds of millions of people who live downstream of these “natural water towers”.
- Between 2000 and 2019, glaciers lost 267 gigatonnes (Gt) of ice per year, equivalent to 21% of sea-level rise.
- The mass loss was equivalent to submerging the surface of England under 2 metres of water every year.
- This was 47% higher than the contribution of the melting ice sheet in Greenland and more than twice that from the ice sheet in Antarctica. As a cause of sea-level rise, glacier loss was second only to thermal expansion, which is prompted by higher ocean temperatures.
- The pace of glacier thinning outside of Greenland and Antarctica picking up from about a third of a metre per year in 2000 to two-thirds in 2019.
- The study uses historical Nasa satellite data and new statistical methods to construct three-dimensional topographies going back 20 years and covering 99.9% of the world’s glaciers.
- Alaska accounted for 25% of the global mass loss, the Greenland periphery 12% and north and south Canada 10% each. The Himalayas and other parts of high-mountain Asia lost 8%, as did the southern Andes and subantarctic regions.
- Smaller, lower glaciers did not contribute as much in volume, but they were the most vulnerable to change. The thinning of New Zealand’s glaciers increased seven-fold between 2000-04 and 2015-19. Thinning rates in the European Alps were twice the global average.
- India and China are depleting underground sources and relying on river water, which substantially originates from glaciers during times of drought.
- This will be fine for a few decades because glaciers will keep melting and provide more river runoff, which acts as a buffer to protect populations from water stress.
- But after these decades, the situation could go downhill. If we do not plan ahead, there could be a crisis for water and food, affecting the most vulnerable.
