Explanation:

SWAMIH Fund
In November 2019, the Finance Minister had cleared a proposal to set up a ‘Special Window’ called SWAMIH in to provide priority debt financing for the completion of stalled housing projects.
SWAMIH Investment Fund has been formed to complete the construction of stalled, brownfield, RERA registered residential developments that are in the affordable housing / mid-income category.
The Sponsor of the Fund is the Secretary, Department of Economic Affairs, Ministry of Finance, and Government of India on behalf of the Government of India.
The fund is set up as a Category-II AIF (Alternate Investment Fund) debt fund registered with SEBI and would be professionally run.
Why need such funds?
Several real estate projects have suffered due to a combined effect of two changes in the real estate sector.
On one hand, incremental launches and slow sales have increased unsold inventory in each project.
While the effect has then got compounded by the fact that consumer preference is now towards completed projects rather than under-construction projects.
This preference has developed as consumers are largely avoiding taking project completion risk and instead are more inclined to completed projects.

INDSAT Exam
The Indian Scholastic Assessment or IND-SAT is a standardized online proctored test for students seeking scholarships with Study in India (SII).
This exam is to gauge the capability and tenacity of students applying to study in India.
The scores will serve as a criterion to shortlist the meritorious students for the allocation of scholarships for undergraduate as well as postgraduate programmes under ‘Study in India’ programme.
The exam is conducted in the proctored internet mode by the National Testing Agency.

Green-Ag Project
The Green-Ag project is designed to achieve multiple global environmental benefits in at least 1.8 million hectares (ha) of land in five landscapes, with mixed land-use systems.
It aims to bring at least 104,070 ha of farms under sustainable land and water management.
The project will also ensure 49 million Carbon dioxide equivalent (CO2eq) sequestered or reduced through sustainable land use and agricultural practices.
Implementing agencies
The project is funded by the Global Environment Facility, while the Department of Agriculture, Cooperation, and Farmers’ Welfare (DAC&FW) is the national executing agency.
Other key players involved in its implementation are the Food and Agriculture Organization (FAO) and the Environment Ministry (MoEF&CC).
Regions of implementation
The project has been launched in high-conservation-value landscapes of five States namely

Madhya Pradesh: Chambal Landscape
Mizoram: Dampa Landscape
Odisha: Similipal Landscape
Rajasthan: Desert National Park Landscape
Uttarakhand: Corbett-Rajaji Landscape

Explanation:

What is Ammonia and what are its effects?

Ammonia is a colourless gas and is used as an industrial chemical in the production of fertilizers, plastics, synthetic fibres, dyes and other products.
Ammonia occurs naturally in the environment from the breakdown of organic waste matter, and may also find its way to ground and surface water sources through industrial effluents or through contamination by sewage.
If the concentration of ammonia in water is above 1 ppm it is toxic to fishes.
In humans, long term ingestion of water having ammonia levels of 1 ppm or above may cause damage to internal organs.

A cause of concern

The level of ammonia in raw Yamuna water was 1.8 parts per million (ppm).
The acceptable maximum limit of ammonia in drinking water, as per the Bureau of Indian Standards, is 0.5 ppm.
Where does Ammonia come from?
Ammonia is produced for commercial fertilizers and other industrial applications.
Natural sources of ammonia include the decomposition or breakdown of organic waste matter, gas exchange with the atmosphere, forest fires, animal and human waste, and nitrogen fixation processes.

How is it treated?
The DJB at present does not have any specific technology to treat ammonia.
The only solution it adapts is to reduce production at its water treatment plants.
In addition to this, the board mixes raw water that carries a high concentration of ammonia with a fresh supply.
The amount of chlorine added to disinfect raw water is also increased when high levels of ammonia are detected.

Explanation:

The Earth formed approximately 4.5 billion years ago, along with the other seven planets in the solar system. As the Earth cooled, a primitive atmosphere was created by the out-gassing of early volcanoes. The early atmosphere contained no oxygen and would have been toxic to human beings, as well as most other life on Earth today.

Based on an analysis of gases vented by modern volcanoes, it seems likely that this early atmosphere consisted mostly of water vapour (H2O) and carbon dioxide (CO2) and nitrogen gas (N2).

In the whole process of evolution, the living organism changed the chemical composition of the Atmosphere. For example, oxygen came from the photosynthesis.
