The National Highways Authority of India (NHAI) has come up with a list of high-traffic density corridors for private developers to build and operate under the build-operate-transfer (BOT) model.

About build-operate-transfer (BOT) Model:

• It is a type of agreement often used in infrastructure projects, particularly in the construction and operation of public facilities or utilities.
• It is a conventional public-private partnership (PPP) model in which a private entity (usually a company or consortium) is granted the rights and responsibilities to design, finance, construct, operate, and maintain a specific project or facility for a defined period of time.
• The private entity, known as the "concessionaire" or "developer," bears the financial and operational risks associated with the project during the contract period.
• The typical lifecycle of a BOT contract involves three phases:
• Build: The concessionaire is responsible for financing, designing, and constructing the infrastructure project. This phase usually includes obtaining the necessary permits and approvals.
• Operate: After the construction is completed, the concessionaire operates and maintains the facility for a specified duration. This can involve providing services, managing operations, and generating revenue from the facility (e.g., tolls, fees, or user charges).
• Transfer: At the end of the contract period, the ownership and control of the facility are transferred back to the government or public authority, which may have been the original owner. The transfer is often accompanied by a predetermined valuation or compensation mechanism.
• The private company gains revenue during the concession period, while the government benefits from infrastructure development without upfront investment.
• However, the specifics of the financial arrangements and incentives vary depending on the individual BOT contract.
• BOT is particularly well-suited for greenfield projects (new projects without prior work) and large-scale, capital-intensive projects. 

Hence option c is the correct answer.

The Union Minister for Power and New & Renewable Energy recently informed about the installation of Flue Gas De-sulphurisation (FGD) equipment in thermal power plants.

About Flue Gas De-sulphurisation (FGD):

• It is a technology to eliminate sulfur dioxide (SO2) from exhaust emissions.
• Where does Sulfur Dioxide come from?
• Fossil fuels such as coal and oil often contain high amounts of sulfur, and when these fuels are burned, around 95% or more of the sulfur is converted to sulfur dioxide (SO2), which is emitted as flue gas.
• Sulfur dioxide in itself is a major air pollutant which impacts all life. It is also a precursor of acid rain, which has significant adverse impacts on forests, freshwaters, and soils, in turn killing insect and aquatic life forms, causing paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues.
• The removal of sulfur dioxide is critical to establishing a safe and clean environment where toxic emissions are kept to a safe level.
• FGD Process:
• FGD is done through the addition of absorbents, which can remove up to 95% of the sulphur dioxide from the flue gas.
• Substances such as ammonia or sodium sulphite are used as absorbents; however, the use of lime or limestone slurry (wet limestone scrubbing) is also widespread. 
• The uncleaned flue gas is sprayed in a scrubber tower (absorber tower) with a mixture of water and limestone (scrubbing slurry), whereby most of the sulphur dioxide is bonded by chemical reaction.

Hence option d is the correct answer.

Researchers recently demonstrated a new lab-based method to detect traces of Forever Chemicals from food packaging material, water, and soil samples in just three minutes or less.

About Forever Chemicals:

• PFAS (Per- and polyfluorinated alkyl substances), also known as the Forever Chemicals, are a large chemical family of over 4,700 highly persistent man-made chemicals.
• These were first developed in the 1940s and are now found in a variety of consumer products, including nonstick pans, water-resistant textiles, and fire suppression foams, due to their ability to repel both grease and water.
• PFAS are the most persistent synthetic chemicals to date. They hardly degrade in the natural environment and have been found in the blood of people and animals all over the world, and are present at low levels in a variety of food products.
• The secret to PFAS’s indestructibility lies in its chemical bonds. PFAS contains many carbon-fluorine bonds, which are the strongest bonds in organic chemistry.
• These chemicals also cause pollution at every stage of production. At the PFAS chemical manufacturing facilities and garment factories, they often contaminate the air, water, and soil of the surrounding environment.
• Exposure to PFAS is linked to cancers, weakened immune systems among children, weight gain, and a wide range of other health problems.

Hence only statement 2 is correct.

In an attempt to hit a target in Kyiv, Russian forces launched a 3M22 Zircon missile recently.

About Zircon Missile:

• The 3M22 Zircon, or SS-N-33, is a scramjet-powered maneuvering anti-ship hypersonic cruise missile developed in Russia.
• Features:
• The missile is reportedly capable of flying with speeds up to Mach 9 and a range of 1000 km.
• It’s a two-stage missile that uses solid fuel in the first stage and a scramjet motor in the second stage. 
• Zircon cruise missiles use cooled supersonic combustion ramjet engines, which power combustion by compressing air flowing at supersonic speeds due to the missile’s forward motion.
• This is in contrast to other hypersonic weapons like the China-made DF-17 or the Russian-made Avangard, which use a Hypersonic Glide Vehicle (HGV), which rely on the initial momentum provided by multi-stage rocket boosters like those used on a ballistic missile to accelerate them to hypersonic speeds.
• Guidance System: Active and Passive Radar Seeker.
• Another valuable aspect of the missile is its plasma cloud. During flight, the missile is completely covered by a plasma cloud that absorbs any rays of radio frequencies and makes the missile invisible to radars. 

Hence only statement 2 is correct.

Scientists at the University of California, Riverside have unveiled a new species of nematode, Steinernema adamsi, a minuscule yet potent ally in the battle against crop pests.

• This new species is a member of a family of nematodes called Steinernema that have long been used in agriculture to control insect parasites without pesticides.
• Steinernema are not harmful to humans or other mammals and were first discovered in the 1920s.
• This new species is part of a special group of nematodes considered beneficial to humans because it can infect and kill insect pests
• It is an entomopathogenic nematode that crawls inside of an insect, defecates highly pathogenic bacteria into its blood and then combines with that bacterium to kill the insect host.

Hence option d is the correct answer.
