The Sekh Hemp is a rope made out of sabai grass fibers which are sundried like the present rice technique,braided together into a larger and stronger form. These ropes have tensile strength and so can be used for dragging and lifting. The rope is thicker and stronger than a similarly constructed cord. The disadvantage of this kind of rope is that it is not long enough for Sabai Grass's average leaf length and is almost like ordinary grass.

Gregorio Esteban Sánchez Fernández (28 May 1932, Málaga – 11 November 2017, Málaga), known as Chiquito de la Calzada, was a Spanish flamenco singer and actor, although he was more famous as a stand-up comedian. Chiquito de la Calzada became very popular in Spanish TV shows (especially Genio y figura) during the mid-nineties due to his unique style, strongly based on a surreal approach to jokes and language and constant movement while telling his jokes, putting his hands in his waist as if he was in pain. Some of his characteristic words and expressions such as fistro or jarl as well as his humorous comparisons such as "this is more dangerous than a shooting in an elevator" quickly became memes and are now part of Spanish slang. His moves and jargon were so influential to other Spanish comedians, that some TV characters such as Crispín Klander, Lucas Grijander and Nuñito de la Calzada were entirely built around his own repertoire. There is a mod for the video game Doom featuring his voice. On 18 February 2019 he received the Medalla de Oro al Mérito en las Bellas Artes.

Hamid Karzai International Airport (Pashto: د حامد کرزي نړيوال هوايي ډګر‎; Dari: میدان هوائی بین المللی حامدکرزی‎; IATA: KBL, ICAO: OAKB) also known as HKAIA is located 5 km from the city centre of Kabul in Afghanistan. It serves as one of the nation's main international airports and as one of the largest military bases, capable of housing over one hundred aircraft. It was previously named Kabul International Airport and locally as Khwaja Rawash Airport, though it continues to be officially known by some airlines by the latter name. The airport was given its new name in 2014 in honor of former President Hamid Karzai. The decision was made by the National Assembly of Afghanistan and the Cabinet of the then President Ashraf Ghani. The airport has been expanded and modernized since about 2005. A new international terminal was added and the older terminal is now used for domestic flights. A number of military bases were also built around the airport, which are used by the United States Armed Forces and NATO's Resolute Support Mission (RS) (formerly International Security Assistance Force, ISAF). The Afghan Air Force also had a base there, while the Afghan National Police provided security inside the passenger terminals. It provides scheduled flights to and from Pakistan, India, Iran, China, Turkey, Russia, Uzbekistan, Tajikistan and the Arab Gulf states. As of June 2016, the most frequently serviced destination from the airport was Dubai-International, with no fewer than four passenger airlines flying the route, and some with multiple daily flights. After the takeover of Kabul by the Taliban in August 2021, all civilian flights were cancelled and suspended until further notice. Only the US and NATO forces are still present in the airport, while the Afghan National Army and the Afghan National Police have dispersed and stopped patrolling the area. Around 500 - 600 Afghan troops mostly from the Afghan Commandos have joined US forces in order to secure the airports outer perimeter. On 17 August 2021 the airport reopened to military traffic, after 7 people died attempting to flee the previous day. At times, U.S. and Taliban forces have fired crowd control shots at the Kabul airport.
