Every day of Maslenitsa plays a great role. On Monday people greet the holiday with games such as sledding, snowballs, riding on swings and so on. Russian people believe that happiness and joy which they feel during this day will accompany them throughout a year. On Tuesday people play games and bake pancakes which are called "blini". Blini are the most popular food which is made during this holiday. These pancakes have a round form and symbolize the Sun and warmth. On Wednesday people usually visit their friends and relatives and treat each other with blini. On Thursday by tradition people try to drive away winter by riding on horses around the village or around the places they live. Friday is usually called “Mothers’-in-law evenings” because sons-in-law come to visit their mothers-in-law. On merry Saturday everyone goes to visit their relatives. All people drink and eat as much as they want and play different games. Sunday is the last day of the holiday. It is also called the "Sunday of forgiveness" because on this day everyone asks forgiveness from relatives and friends for offences and mistakes committed against them. The most appropriate answer is “God will forgive”. After that people usually sing songs, dance and at the end of the day they burn the doll.
Maslenitsa is also considered as a family holiday because spring is a symbol of new life. People who marry during this time are considered as very strong and happy couples who will give a birth to many children. During Maslenitsa some people even “punish” those who did not marry yet by throwing them into snow.
Lockheed Martin F-35 Lightning II
The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, fifth generation multirole Fighter aircraft under development to perform ground attack, reconnaissance, and air defense missions with stealth capability.
The development of the F-35 has been very controversial. Many people feel like the US Air Force has been spending too much money on the F-35 project, and that the government should halt all development of the project.

On 7 December 2020, the CEO of the corporation , Sergey Chemezov, said that the first serially manufactured Sukhoi-57 with a first stage engine would be provided for the Russian military by the end of 2020, and the first Sukhoi-57 equipped with the second stage engine would be assembled in 2022. Defense Minister Sergei Shoigu told the Defense Ministry’s board meeting that a total of 22 Sukhoi-57 planes would be provided by the end of 2024. Under a contract concluded in 2019 a total of 76 Sukhoi-57s are to be delivered by the end of 2028.
The Blues Band
The Blues Band is a British blues band. The band was formed in 1979 by veteran musicians of British blues of the 1960s.
The band was formed in 1979.
In the 1960s Paul Jones and Tom McGuinness played for Manfred Mann. Jones worked also as actor and radio DJ.As a harmonica man, he has performed publicly and/or recorded with Memphis Slim, Alexis Korner, Henry Gray, Alvin "Youngblood" Hart, Susan Tedeschi, Eric Bibb and Otis Grand. Hughie Flint was the drummer of John Mayall's Bluesbreakers. Together with McGuinness he later formed McGuiness Flint who had a hit with "When I´m dead and gone". Dave Kelly was guitarist in the John Dummer Blues Band and in the touring bands of Howlin' Wolf and John Lee Hooker. They played together mostly in London pubs just for fun about playing rhythm ´n blues.
Their first album ""The Official Blues Band Bootleg Album"" raised no interest with record labels, so they sold it during concerts and via mail order. The record was a fine mixture of blues standards and own songs. Arista signed with the band and the album reached #40 in the charts. 1982 Hughie Flint left the band and was replaced by Rob Townsend. In 1983 they parted but they came together soon.
When not playing with the Blues Band Jones, McGuinness and Townsend are playing with ""The Manfreds"". The band can be seen as the 1960s Manfred Mann Band without the leader. Dave Kelly plays often with his ""The Dave Kelly Band"".
By playing a lot of concerts all over Europe they had and still have a lot of fans. Till present they recorded over 20 albums. It is said, that three generations of a family can be seen in their concerts.
Acute (medicine)
In medicine, an acute disease or condition either happens for a short time, as in acute infection, or doesn't last long. The word acute may often be confused by the general public to mean 'severe'. This is different: something can be acute but not severe.
The word "acute" is in the name of many diseases, for example, severe acute respiratory syndrome or acute leukemia.
Acute hospitals are hospitals which are meant for short-term medical and/or surgical treatment and care. The related medical speciality is called acute medicine.
Subacute is described as between acute and chronic. An example is subacute fever symptoms or subacute endocarditis.
Toxicity
Toxicity is the degree to which a substance can damage an organism. It is the subject-matter of toxicology.
A central idea in toxicology is that almost everything is toxic when taken to excess. Effects are dose-dependent: even water can lead to 'water intoxication' when taken in too much. For even a very toxic substance such as elapid snake venom there is a dose below which there is no toxic effect.
Toxicity is species-specific. A dose which is toxic to one animal may not be toxic to another.
Acute toxicity describes the bad effects of a substance that come either from a single exposure, or from many exposures in a short amount of time (usually less than 24 hours). To be known as "acute" toxicity, the bad effects should happen within 14 days of the substance thouching something.
Acute toxicity is different from chronic toxicity. Chronic toxicity talks about the bad health effects from many exposures, often at lower levels, to a substance over a longer amount of time (months or years).
It is widely thought to be wrong to use humans as tests for acute (or chronic) toxicity research. However, some information can be picked up from investigating cases when humans accidentally make contact with the substance (e.g., factory accidents). Otherwise, most acute toxicity data comes from animal testing or, more recently, "in vitro" testing methods and inference from data on similar substances.
Kan'ei
The "nengō" "Kan'ei" means "Permanent Liberality".
Hayashi Razan and his son wrote "Kan'ei shoka kezuden" in 1641-1643. The shogun ordered the writing of this history of the great clans of Japan.
Protostar
Protostar is an early stage in the evolution of a star that usually grows to the point of beginning nuclear fusion and becoming a star by gathering mass. It is made of a contracting cloud of cold and dark interstellar medium (mostly hydrogen gas). Protostars has lower temperature than an ordinary star. For a sun-like star, deuterium fusion occurs in the protostar stage, while proton-proton fusion, which sustains stars for billions of years, starts gradually millions of years later. The modern picture of protostars was first suggested by Chushiro Hayashi in 1966.
Although outer space may seem empty, it is actually full of thinly spread gas and dust called the interstellar medium. Higher density regions form clouds, or nebulas, where star formation takes place. The gas is mostly molecules of hydrogen, so these nebulae are called molecular clouds. The largest molecular clouds have densities of 100 particles per cm3, diameters of 100 light-years (9.5×1014 km), and masses up to 6 million solar masses, and an average interior temperature of 10 K. This is cold and dense compared to elsewhere in space, but would be considered a vacuum on Earth. With low temperatures and high densities, gravity can overcome thermal pressure and start the gravitational collapse that will form a star.
