Progressive bluegrass is a type of bluegrass music which became popular in the 1960s and 1970s. The four important elements (not always all present) of progressive bluegrass are instrumentation (usually including electric instruments, drums, piano, and more), songs imported or styles imitated from other musical genres (like jazz, rock and others), non-traditional chord progressions, and lengthy "jam band"-style improvisation.
Bands such as Nickel Creek produce music in this style.
Hot Country Songs
Hot Country Songs is a chart published weekly by "Billboard magazine" in the United States.
This 60-position chart lists the most popular country music songs, calculated weekly mostly by airplay and occasionally commercial sales. Currently, the chart does not count digital downloads towards chart tabulation (although singles that are only available as downloads do chart if they receive enough airplay).
Neverland
Neverland is a fictional island that is the setting for the novel Peter Pan by J.M. Barrie. Peter Pan, his gang of "Lost Boys" and Tinkerbell, the fairy, live on Neverland. A gang of pirates led by Captain Hook and a band of Native Americans ("redskins" in the story) also live on the island.
Neverland is a land of fantasy where no one gets older and Peter Pan remains a child forever. To reach Neverland, Peter Pan states one must fly "second to the right, and straight on till morning".
International Bluegrass Music Association
The International Bluegrass Music Association, or IBMA, is a trade association to promote bluegrass music.
Formed in 1985, IBMA established its first headquarters in Owensboro, Kentucky. In 1988 they announced plans to create the International Bluegrass Music Museum as a joint venture with RiverPark Center in Owensboro. In 1990 IBMA established the World of Bluegrass, a combination trade show, concert, and awards presentation. This was originally set in Owensboro, before moving to Louisville, Kentucky in 1997. Nashville, Tennessee hosted this event in 2005 and 2006, and will continue as the host location in the future. In 1991 IBMA established the International Bluegrass Music Hall of Honor at the International Bluegrass Music Museum to recognize lifetime contributions to bluegrass, both by performers and non-performers. In 2003 IBMA relocated its offices to Nashville, Tennessee.
Country Music Association Awards
The Country Music Association Awards, also known as the CMA Awards, or the CMAs, are music awards voted on by business members of the Country Music Association.
The Used
The Used are an American post hardcore band. They formed in the year 2000 and have released a number of albums since then. Their first album was called "The Used". Their latest album is called "Heartwork", and was released in 2020.
They have always been signed to one record label named Reprise. In 2004, singer Bert McCracken's girlfriend at the time was pregnant with their child and she died from a drug overdose. For that reason, their second album was named "In Love and Death". Around that time, the band also took on a new drummer.
Bobo-Dioulasso
Bobo Dioulasso is a city in Burkina Faso. It is the second largest city in Burkina Faso. A census taken in 2006 stated that 435,543 people lived in the city; 215,968 were male and 219,575 were female.
Koudougou
Koudougou is a city in Burkina Faso. It is the third largest city in Burkina Faso. A census taken in 2006 stated that 82,720 people lived in the city; 40,229 were male and 42,491 were female.
Banfora
Banfora is a city in Burkina Faso. It is the fourth largest city in Burkina Faso. A census taken in 2006 stated that 72,144 people lived in the city; 36,392 were male and 35,752 were female.
Ouahigouya
Ouahigouya is a city in Burkina Faso. It is the fifth largest city in Burkina Faso. A census taken in 2006 stated that 70,957 people lived in the city; 35,017 were male and 35,940 were female.
In July 2010, the US Government warned Americans that there was a real danger that they might be kidnapped by terrorists in the city.
Chirality
Chirality is when an object is present in two forms which are mirror images of each other.
The two forms cannot be superimposed. Human hands are chiral. The left hand is a mirror image of the right hand. You cannot turn or move one of your hands to look exactly the same as the other. This is why you can not put a left handed glove on your right hand, or shake the right hand of a person using your left hand.
In chemistry, chirality refers to molecules. If a molecule is chiral it has two forms that are mirror images of each other but "otherwise identical".
Chemists call these "enantiomers" or "optical isomers". Because the difference between right and left hands is easy to understand, chemists call enantiomers either 'right-' or 'left-handed'. A mixture of equal amounts of the two enantiomers is called a "racemic mixture".
Molecular chirality is quite common. It is found in stereochemistry, inorganic chemistry, organic chemistry, physical chemistry, and biochemistry.
The symmetry of a molecule (or any other object) tells us whether it is chiral. A molecule is "achiral" (not chiral) if it has an axis of symmetry.
A racemic mixture is one which has equal amounts of left- and right-handed enantiomers of a chiral molecule.
Many biologically active molecules are chiral, including amino acids (the building blocks of proteins) and sugars. Most of these compounds are of the same chirality. Most amino acids are (left-handed) and sugars are . (right-handed). Proteins made of amino acids, are known as "left-handed proteins", whereas amino acids produce "right-handed proteins".
The origin of homochirality in the first place is much discussed. Most believe that the original origin of chiralities was purely random. They think if carbon-based life forms exist elsewhere in the universe, the chemistry might have different chirality. Other theories are possible.
Enzymes, which are chiral, usually only work with one enantiomer of a chiral substrate. Imagine an enzyme as having a glove-like cavity that binds a substrate. If this glove is right-handed, then one enantiomer will fit inside and be bound, whereas the other enantiomer will have a poor fit and is unlikely to bind.
It was economical for life-forms to adopt one form or the other of each type of chiral compound. That way we do not need two enzymes for every chemical reaction which involves chirality.
Londrina
Londrina is a city in Brazil. It is found in the northern area of the state of Paraná. It is 369 km away from the capital, Curitiba. Londrina has 510.707 people living in the city. This makes it the second biggest city of Paraná and the third biggest city in Southern Brazil.
Kaya
Kaya is a city in Burkina Faso. It is the sixth largest city in Burkina Faso. A census taken in 2006 stated that 51,778 people lived in the city; 25,898 were male and 25,880 were female.
Superimposition
In graphics, superimposition is when an image or video is put on top of an already-existing image or video. This is usually done to add to the overall image effect or to hide something (such as when a different face is superimposed over the original face in a photograph).
This technique is used in cartography to produce photomaps by superimposing grid lines, contour lines and other linear or textual mapping features over aerial photographs.
