The Tejas MK-1A is an enhanced version of the Tejas Mark 1 light combat aircraft (LCA) developed by Hindustan Aeronautics Limited (HAL) in India. It is a single-engine, delta-winged aircraft with a glass cockpit and canard control surfaces. The Tejas MK-1A is equipped with a more powerful engine, an active electronically scanned array (AESA) radar, and an improved electronic warfare suite. It also has a larger weapons payload and a longer range than the Tejas Mark 1.
The Tejas MK-1A is currently in production and is expected to be inducted into the Indian Air Force (IAF) in 2024. The IAF has ordered 83 Tejas MK-1A aircraft, with an option to order an additional 100 aircraft.
The Tejas MK-1A is a significant upgrade over the Tejas Mark 1 and will provide the IAF with a more capable and modern fighter aircraft. It is also expected to be a competitive export product, with HAL already having received interest from several countries.
Tejas MK-1A:
1.A more powerful engine: The Tejas MK-1A is powered by a General Electric F414-INS6 engine, which provides a significant increase in thrust over the Tejas Mark 1’s GE F404-GE-IN20 engine. This will give the Tejas MK-1A a higher top speed and a longer range.
2.An AESA radar: The Tejas MK-1A is equipped with an EL/M-2052 AESA radar, which provides a significant improvement in radar performance over the Tejas Mark 1’s mechanically scanned radar. The AESA radar will give the Tejas MK-1A a better ability to detect and track targets, as well as to engage multiple targets simultaneously.
3.An improved electronic warfare suite: The Tejas MK-1A is equipped with an improved electronic warfare suite, which will give it a better ability to defend itself against enemy radar and missile threats.
4.A larger weapons payload: The Tejas MK-1A can carry a larger weapons payload than the Tejas Mark 1, including air-to-air missiles, air-to-surface missiles, and bombs.
5.A longer range: The Tejas MK-1A has a longer range than the Tejas Mark 1, thanks to its more powerful engine and larger fuel capacity.
6.The Tejas MK-1A is a significant upgrade over the Tejas Mark 1 and will provide the IAF with a more capable and modern fighter aircraft. It is also expected to be a competitive export product.

3.Hoolock Gibbon
Hoolock gibbon:
The hoolock gibbon is a species of ape native to eastern Bangladesh, Northeast India, Myanmar, and Southwest China. It is the only ape found in India.
Hoolocks are the second-largest of the gibbons, after the siamang. They reach a size of 60 to 90 cm and weigh 6 to 9 kg. The sexes are about the same size, but they differ considerably in coloration; males are black-colored with remarkable white brows, while females have a grey-brown fur, which is darker at the chest and neck. White rings around their eyes and mouths give their faces a mask-like appearance.
Hoolocks are arboreal animals and spend most of their time in the trees. They are excellent climbers and leapers, and they can travel long distances through the trees. Hoolocks are also vocal animals and use a variety of calls to communicate with each other. Their most famous call is the “whoo” call, which they use to announce their territory.
Hoolocks are frugivores and their diet consists mainly of fruits, leaves, and flowers. They also eat insects, small mammals, and eggs.
Hoolocks are social animals and live in groups of 2 to 6 individuals. The groups are usually monogamous, with a single breeding pair. The females give birth to a single offspring after a gestation period of about 7 months.
Hoolocks are listed as endangered on the IUCN Red List. The main threats to their survival are habitat loss and fragmentation, hunting, and the illegal pet trade.
Here are some interesting facts about hoolock gibbons:
1.They are the only apes that can walk bipedally for short distances.
2.They are the loudest land animals in Asia, their calls can be heard up to 3 kilometers away.
3.They are very territorial and will defend their territory against other gibbons.
4.They are monogamous and the male and female will work together to raise their young.
4.Dengue
Dengue is a mosquito-borne illness that is caused by the dengue virus. It is a major public health problem in tropical and subtropical regions around the world.
The symptoms of dengue can vary from mild to severe. They usually start 4-10 days after being bitten by an infected mosquito. The most common symptoms include:
1.Fever
2.Rash
3.Headache
4.Muscle and joint pain
5.Nausea and vomiting
6.Diarrhea
In some cases, dengue can develop into a more severe form called dengue hemorrhagic fever (DHF). DHF is a life-threatening condition that can cause bleeding, low blood pressure, and organ failure.
There is no specific treatment for dengue. Treatment is supportive and includes rest, fluids, and pain relievers. In severe cases, hospitalization may be necessary.
There are a number of things that can be done to prevent dengue, including:
1.Avoid mosquito bites. This can be done by using insect repellent, wearing long sleeves and pants, and staying indoors during peak mosquito hours (dawn and dusk).
2.Get vaccinated. There is a vaccine available for dengue, but it is not yet widely available.
3.Support mosquito control programs. This can help to reduce the number of mosquitoes in your community.

Crimea:
- Crimea is a peninsula in Eastern Europe, located at the southern tip of the Black Sea.
- It is surrounded by Ukraine to the north and east, the Black Sea to the south, and the Sea of Azov to the northeast.

The history of Crimea is long and complex. The peninsula has been ruled by a number of different empires and states, including the Greeks, the Romans, the Byzantines, the Ottomans, and the Russians.
In the early 20th century, Crimea was part of the Russian Empire. After the Russian Revolution, Crimea became an autonomous republic within the Soviet Union. In 1954, Crimea was transferred to the Ukrainian Soviet Socialist Republic.
In 1991, Ukraine declared independence from the Soviet Union. Crimea remained part of Ukraine, but there was a large Russian minority in the peninsula who wanted to be part of Russia.
In 2014, Russia annexed Crimea after a disputed referendum. The annexation was condemned by most countries, and Ukraine has not given up its claim to Crimea.
The status of Crimea remains a source of tension between Russia and Ukraine.
