Explanation:

A thrombectomy is a surgical or interventional treatment to remove blood clots in an artery or vein to help restore blood flow through your blood vessel. A blood clot, also known as a thrombus, can obstruct blood flow, leading to tissue damage or even death. Some of the most common places for blood clots to occur are your legs, arms, intestines, brain, lungs and heart. Thrombectomies are performed to restore blood flow and prevent serious consequences. Sometimes a thrombectomy must be performed within a matter of hours to prevent life- or limb-threatening complications from occurring. There are two large categories of thrombectomies:

Surgical (open) Thrombectomy — During a surgical thrombectomy, your surgeon makes an incision to get to your blocked blood vessel, cuts open your blood vessel, removes the blood clot using a balloon and then repairs the blood vessel.

Percutaneous (minimally invasive) Thrombectomy — During a mechanical thrombectomy, your surgeon introduces special devices through catheters that can either macerate or suction out clots from within your blood vessel. When there’s a residual clot left, your surgeon will infuse the area with local clot-dissolving medicines.

Explanation:

Zangezur Corridor is a proposed transport route designed to connect Azerbaijan’s mainland with its exclave, the Nakhchivan Autonomous Republic, bypassing Armenia’s Syunik Province. Zangezur, which is currently part of southern Armenia, has been a disputed territory since World War I. On Azerbaijan’s side, the corridor would be integrated into the Horadiz-Agbend transport highway and railway network. On Turkey’s side, it would link into the Nakhchivan-Igdir-Kars railway and highway, providing a direct land route to Anatolia and beyond. It carries significant economic and strategic weight for the South Caucasus and beyond. The project aims to enhance Azerbaijan’s trade with Turkey and Europe by improving logistics infrastructure, reducing transportation costs, and significantly cutting travel time between Azerbaijan and Nakhchivan. The Zangezur Corridor plays a crucial role in increasing regional connectivity — not only throughout Caucasia, but also across greater Eurasia, joining Turkish, Russian, Central Asian, Iranian and Armenian territories and linking Europe to Asia.

Explanation:

Advance Authorisation is issued to allow duty-free import of input, which is physically incorporated in the export product (making normal allowance for wastage). The inputs imported are exempt from duties like Basic Customs Duty, Additional Customs Duty, Education Cess, Anti-dumping duty, Safeguard Duty and Transition Product-Specific Safeguard duty, Integrated tax, and Compensation Cess, wherever applicable, subject to certain conditions. An export obligation is usually set as a condition for issuing Advance Authorisation. In addition to any inputs, packaging material, fuel, oil and catalysts which are consumed/utilised in the process of production of export products, are also allowed. The quantity of inputs allowed for a given product is based on specific norms defined for that export product, which considers the waste generated in the manufacturing process. The Directorate General of Foreign Trade (DGFT) provides a sector-wise list of Standard Input-Output Norms (SION) under which the exporters may choose to apply. Alternatively, exporters may apply for their own ad-hoc norms in cases where the SION does not suit the exporter. It is available to either a manufacturer exporter directly or a merchant exporter tied with a supporting manufacturer.

Explanation:

NOTAM is an official alert issued to pilots and airlines about temporary changes or hazards in flight operations—such as airspace closures, route changes, or construction—that may affect flight safety or planning. NOTAMs are issued by the civil aviation authority of a country. In India, it is issued by the Airports Authority of India (AAI). These notices are then distributed through international aviation networks to inform pilots and airlines globally.
