About Steel Import Monitoring System’ 2.0 Portal:

• It features API integration with multiple government portals, enhancing quality control and streamlining processes for improved efficiency and effectiveness.
• The portal boasts a robust data entry system, ensuring consistent and authentic data, which promotes transparency and accountability. Integration of various databases enable stakeholders to locate areas of risk and, thereby, permit better risk management.
  • Example: If an import consignment declares a particular source of import, which is not licensed by BIS, then the Ministry will be enabled to not recommend its import. The detailed data will enable Customs to conduct better analysis and risk management of steel imports.
• SIMS was introduced in 2019, and has played a crucial role in providing detailed steel import data to the domestic industry.
• Based on industry feedback, the Ministry has revamped the portal to develop a more effective SIMS 2.0, a significant step forward in monitoring steel imports and promoting the growth of the domestic steel industry.
• Significance: Availability of such detailed data not only provides input for policy making but also signals areas for production and growth to the domestic steel industry.

About Cultural Property Agreement:

• It is to prevent and curb the illicit trafficking of antiquities from India to the USA.
• It is aligned with the 1970 UNESCO Convention on the Means of Prohibiting and Preventing the Illicit Import, Export and Transfer of Ownership of Cultural Property, to which both countries are States party.
• It restricts the importation into the United States of America of certain archaeological material ranging in date from 1.7 million years ago through 1770 CE and certain ethnological material, which may include categories of civic, religious and royal architectural material, religious material and ceremonial items, and manuscripts ranging in date from 2nd century BCE to 1947 CE.
• As per the agreement, the United States of America shall offer to return to India any object or material on the Designate List forfeited to the Government of the United States of America.
• It is to be noted that the USA has already executed agreements with countries like: Algeria, Belize, Bolivia, Bulgaria, Cambodia, Chile, China, Colombia, Costa Rica, Cyprus, Ecuador, Egypt, El Salvador, Greece, Guatemala, Honduras, Italy, Jordan, Mali, Morocco, Peru and Turkey.

About Yamunotri Dham:

• It is a part of Char Dham(along with Gangotri, Kedarnath, and Badrinath), the four most revered Hindu pilgrimages in the Himalayas. 
• It is situated at an altitude of 3,293 metres (10,804 ft) in the Garhwal Himalayasin District Uttarkashi, Uttarakhand. 
• It is surrounded by mountains on all sides and lies in close proximity to the Indo-China border.

Key Facts about Yamuna River:

• Yamuna River (also known as Jumna), is the major tributary of the Ganges River.
• Origin: It rises in the high Himalaya, in the Yamunotri Glacier, at the height of 4,421 meters. 
• Course: 
  • The 1,376 km long Yamuna flows solely through India, crossing three states: Uttarakhand, Uttar Pradesh and Haryana.
  • After rising in the high Himalayas, it flows in a southerly direction swiftly through the Himalayan foothills and, exiting Uttarakhand, onto the Indo-Gangetic Plain, along the border between Uttar Pradesh, and Haryanastate to the west.
  • The Eastern and Western Yamuna canals are fed from the river at that point.
  • The Yamuna then passes Delhi, where it feeds the Agra Canal. 
  • South of Delhi, and now wholly within Uttar Pradesh, it turns southeastward.
  • Near Prayagraj (Allahabad), after a course of about 855 miles (1,376 km), the Yamuna joins the Ganges River.
  • The confluence of the two rivers is an especially sacred place to Hindus and is the site of annual festivals as well as the Kumbh Mela, which is held every 12 years.
• Tributaries:
• • Near Dehradun, the capital city of Uttarakhand, the Yamuna is joined by its biggest tributary, the Tons River.
  • The Chambal River is Yamuna’s biggest tributary on the right.
  • Other important tributaries of the Yamuna include the Hindon, Sarda, and Giri rivers on the right and Betwa and Sindh on the left.

Why in the News?

• The rover has identified a rock named "Cheyava Falls" that exhibits intriguing characteristics, suggesting it may have hosted microbial life billions of years ago.
• Cheyava Falls, an arrowhead-shaped rock, was found on the northern edge of Neretva Vallis, an ancient river valley that once channeled water into Jezero Crater, where Perseverance is working. 
• It is rich in chemical signatures and structures that may have been formed by life when the area contained running water.
• The rover's SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals) instrument detected organic compounds in Cheyava Falls.
• These carbon-based molecules are considered the building blocks of life, although they can also be formed by non-biological processes.

About Ahom Dynasty:

• It (1228–1826, called Kingdom of Assamin medieval times) was a medieval kingdom in the Brahmaputra valley in Assam that maintained its sovereignty for nearly 600 years and successfully resisted Mughal expansion in North-East  
• It was able to establish its suzerainty over the Brahmaputra valley and had a profound effect on the political and social life in the region.
• It was established by Sukaphaa, a Shan prince of Mong Mao who came to Assam after crossing the Patkai Mountains.
• Though it came to be called the Ahom kingdom in the colonial and subsequent times, it was largely multi-ethnic, with the ethnic Ahom people constituting less than 10% of the population toward the end. 
• The people of the kingdom used to call them 'Chaopha' or 'Swargadeo'.
• The kingdom came under repeated Mughal attacks in the 17th century, and on one occasion in 1662, the Mughals under Mir Jumla occupied the capital, Garhgaon.
  • The Mughals were unable to keep it, and finally, during the battle of Saraighat in 1671, the Ahoms led by Lachit Borphukan successfully defeated the Mughals.
  • Borphukan is mainly known for his leadership in this battle. 
  • By 1682, the Mughal influence in the region was completely eradicated.
• Following a period of confusion, the kingdom got itself the last set of kings, the Tungkhungia kings, established by Gadadhar Singha.
• The kingdom became weaker with the rise of the Moamoria rebellion, and subsequently fell to a succession of Burmese invasions.
• With the defeat of the Burmese after the First Anglo-Burmese War and the Treaty of Yandabo in 1826, control of the kingdom passed into British (East India Company) hands.

What are Moidams of Ahom dynasty?

• The Moidams (also spelt as Maidam) are burial mounds of Ahom kings, queens, and nobles in Assam.

• These mounds are distinct for their architecture and reflect the Ahom’s foreign influences.
• They are found throughout upper Assam, with Charaideo, the first Ahom capital, being the main necropolis.
• Each Moidam has three main parts:
  • A vault or chamber where the body is placed.
  • A hemispherical earthen mound covering the chamber.
  • A brick structure (Chaw-chali) on top for annual offerings and an octagonal boundary wall with an arched gateway.
• Originally, vaults were made of wooden poles and beams but were replaced with stone and brick during the reign of King Rudra Singha (CE 1696-1714).
• Inside the vault, the dead were buried with their belongings, including clothes, ornaments, and weapons.
