9M133 Kornet
The 9M133 Kornet (Russian: Корнет; "Cornet", NATO reporting name AT-14 Spriggan, export designation Kornet-E) is a modern Russian man-portable anti-tank guided missile (ATGM) intended for use against main battle tanks. It was first introduced into service with the Russian army in 1998. The Kornet is among the most capable Russian ATGMs. It is not intended to fully replace previous systems, due to its high cost. The Kornet comes in variants with thermobaric warheads for use against soft targets. It was further developed into the 9M133 Kornet-EM, which has increased range, fire-and-forget capability, and an improved warhead. The Kornet has been widely exported and is produced under license in several countries. It was first used in combat in 2003 and has since been used in many conflicts. The NATO reporting name AT-14 Spriggan is derived from the spriggan, a legendary creature from Cornish faery lore.

Public Transport in Shanghai
Shanghai has an extensive public transport system, largely based on buses, trolley buses, taxis, and a rapidly expanding metro system. Shanghai has invested heavily in public transportation before and after the 2010 World Expo, including the construction of the Hongqiao transportation hub of high-speed rail, air, metro and bus routes. Public transport is the major mode of transport in Shanghai as limitations on car purchases were introduced in 1994 in order to limit the growth of automobile traffic and alleviate congestion. New private cars cannot be driven without a license plate, which are sold in monthly license plate auctions which is only accessible for locally registered residents and those who have paid social insurance or individual income taxes for over three years. Around 9,500 license plates are auctioned each month, and the average price is about CN¥89,600 (US$12,739) in 2019. Shanghai (population of 25 million) has over four million cars on the road, the fifth-largest number of any Chinese city. Despite this the city remains plagued by congestion and vehicle pollution. The results of the "2011 Shanghai Public Transport Passenger Flow Survey" released by the Municipal Transportation and Port Bureau showed that the city's public transport travel time was gradually reduced. The average travel distance of public transport in 2011 was 8.5 kilometers, the travel time 50.8 minutes per trip and the travel cost of public transport is gradually reduced: in 2011, the cost of rail transit was 2.4 yuan per trip, down 14% from 2005; the cost of bus and tram trips was 1.8 yuan, down 5% from 2005. Metro accounted for 33% of the public transport passenger volume. In 2018 the public transportation system handled a total of 16.05 million rides on average each day, among which 10.17 million (63%) were made via the Metro and 5.76 million (36%) via buses. Shanghai expressway traffic volume was 1.215 million vehicles on an average day.

During her 31-year career, Grampus made significant contributions to the understanding of the mackerel fishery off the United States East Coast , Canada , and the British colony of Newfoundland.

Messaging Apps
Messaging apps (a.k.a. social messaging or chat applications) are apps and platforms that enable instant messaging. Messaging apps are online messaging services used primarily via mobile platforms. Many such apps have developed into broad platforms enabling status updates, chatbots, payments and conversational commerce (e-commerce via chat). They are normally centralised networks run by the servers of the platform's operators, unlike peer-to-peer protocols like XMPP. Some examples of popular messaging apps include WhatsApp, Facebook Messenger, China's WeChat and QQ Messenger, Telegram, Viber, Line, and Snapchat. The popularity of certain apps greatly differ between different countries. Certain apps have emphasis on certain uses - for example Skype focuses on video calling, Slack focuses on messaging and file sharing for work teams, and Snapchat focuses on image messages. Some social networking services offer messaging services as a component of their overall platform, such as Facebook's Facebook Messenger, while others have a direct messaging function as an additional adjunct component of their social networking platforms, like Instagram, Reddit, Tumblr, TikTok, Clubhouse and Twitter, either directly or through chat rooms. Messaging apps are the most widely used smartphone apps, with in 2018 over 1.3 billion monthly users of WhatsApp and Facebook Messenger, 980 million monthly active users of WeChat and 843 million monthly active users of QQ Mobile.

Mediterranean U-boat Campaign (World War II)
The Mediterranean U-boat Campaign lasted from about 21 September 1941 to 19 September 1944 during the Second World War. Malta was an active British base strategically located near supply routes from Europe to North Africa. Axis supply convoys across the Mediterranean Sea suffered severe losses, which in turn threatened the fighting ability of the Axis armies in North Africa. The Allies were able to keep their North African armies supplied. The Kriegsmarine tried to isolate Malta but later it concentrated its U-boat operations on disrupting Allied landing operations in southern Europe.[clarification needed] Some 60 German U-boats made the hazardous passage into the Mediterranean Sea from 1941. Only one completed the journey both ways. Karl Dönitz, the Commander-in-Chief, U-boats, Befehlshaber der Unterseeboote (BdU) was always reluctant to send his boats into the Mittelmeer but he recognised that natural bottlenecks such as the Straits of Gibraltar were more likely to result in shipping being found and attacked than relying on finding it in the vast Atlantic Ocean. The U-boats were sent to assist the Italians, although many were attacked in the Strait of Gibraltar and nine were sunk while attempting the passage and ten more were damaged. The Mediterranean is a clear and calm body of water which made escape more difficult for the U-boats. The Axis failed in their objective.

Auction
An auction is usually a process of buying and selling goods or services by offering them up for bids, taking bids, and then selling the item to the highest bidder or buying the item from the lowest bidder. Some exceptions to this definition exist and are described in the section about different types. The branch of economic theory dealing with auction types and participants' behavior in auctions is called auction theory. The open ascending price auction is arguably the most common form of auction in use throughout history. Participants bid openly against one another, with each subsequent bid required to be higher than the previous bid. An auctioneer may announce prices, bidders may call out their bids themselves or have a proxy call out a bid on their behalf, or bids may be submitted electronically with the highest current bid publicly displayed. Auctions were and are applied for trade in diverse contexts. These contexts are antiques, paintings, rare collectibles, expensive wines, commodities, livestock, radio spectrum, used cars, online advertising, even emission trading and many more.
