VA is a quantitative measure of the ability to identify black symbols on a white background at a standardized distance when the size of the symbols is varied. The VA represents the smallest size that can be reliably identified. VA is the most common clinical measurement of visual function.
Some people may suffer from other visual problems, such as color blindness, reduced contrast, or inability to track fast-moving objects and still have normal visual acuity. Thus, normal visual acuity does not mean normal vision. The reason visual acuity is very widely used is that it is a test that corresponds very well with the normal daily activities a person can handle, and evaluate their impairment to do them.
Robert Baker
Bob Baker (October 26 1926 - April 23 2002) was an American boxer who fought professionally from 1949 to 1960. He was one of the world's leading bulky heavyweight boxers in the 1950s. Bob "The Grinder, Big Bob, The Behemoth" Baker was born in Canonsburg, Pennsylvania. After serving 3 years in the navy, he fought out of Pittsburgh. His most notable accomplishments include the 1949 Pennsylvania Intercity Golden Gloves championship in the heavyweight division. In 1947, he won Pittsburgh Golden Gloves Championship. His amateur record is respectable 33-2. In 1948, Coley Wallace won an unpopular split decision vs. Marciano in the semifinal of the New York Golden Gloves Tournament of Champions and then he won the final of that tournament by an unpopular very close split decision vs 'Big' Bob Baker.
In 1948, Wallace & Baker met again in the final match. This time Baker won & became 1948 Golden Gloves champion again.
Baker started his professional career with 26 undefeated fights before drawing against bulky Kid Riviera but only 10 days later lost to another top boxer, Clarence Henry.
From April 1955 until February of 1956, Bob Baker was ranked as the leading challenger to Rocky Marciano's heavyweight title by IBC-International Boxing Club, however Ring Magazine still rated him as #2. On Wednesday, December 7th 1955, Baker beat Nino Valdez in a rematch, again by unanimous decision. The winner of that fight was scheduled to fight Marciano.
After 13 straight wins (Baker's dozen), Baker lost to Tommy Hurricane Jackson on February 3 1956, in New York's Madison Square Garden. It was a conytorversial split decision win for Jackson. In May 1956, Baker easily defeated John Holman. Baker also lost another controversial split decision rematch with Jackson on September 26 1956. Both fights should have been draws.Opinions on both Baker-Jackson fights were divided in many publications with most of them giving the fight to Baker. United Press scored the fight 7-5 for Baker. A poll of all 13 ringside writers favored Baker 9-4.
After 1956, Baker's success was limited. His most notable victory was a sound unanimous decision defeat of solid Canadian George Chuvalo, the future Canadian heavyweight champion, by unanimous decision on September 9 1957. Chuvalo was also a multiple time championship contender in the 1960s and 1970s.
Baker died on April 23 2002, from acute heart failure, in Pittsburgh, Pennsylvania. He is survived by his son Bob Baker jr.
Michaëlle Jean

She was the Governor General of Canada, replacing Adrienne Clarkson on 27 September 2005, until 1 October 2010 when David Lloyd Johnston took over. She is the Secretary General of "Organisation internationale de la Francophonie" since 2015 and multilingual who speaks English, French, Italian, Spanish, Portuguese and Haitian Creole.

Pascal Duquenne
Pascal Duquenne is a Belgian actor. He was born in Vilvoorde, Flanders, Belgium on 8 August 1970. He was diagnosed with Down syndrome.
It was Jaco van Dormael who noticed him (as Ducquenne was playing theatre). Dormael offered him his first roles in movies.
In 1996 Pascal Duquenne and Daniel Auteuil were awarded a prize (for best male interpretation) at the Cannes Film Festival. Duquenne received the prize for the role of a boy who has Down syndrome. The movie was called "Le Huitième Jour" ("The Eighth Day").
He also has acted in other movies. Currently he lives in Brussels.
Catherine Emmerich
Sister Anne Catherine Emmerich (September 8, 1774 - February 9, 1824) was a German Augustinian nun. She is remembered for her mystical visions of Jesus' and Mary's lives. What she saw was written in books, for example, "The Dolorous Passion of Our Lord, Jesus Christ". The book later had an important part as a main source of information for Mel Gibson's movie "The Passion of the Christ".
She was stuck in bed when marks of stigmata showed up she had doctors and physicians examine her markings, and it was found to be a genuine stigmatic case.

New Year
The New Year is an event that happens when a culture celebrates the end of one year and the beginning of the next year. Cultures that measure yearly calendars all have New Year celebrations. On January 1, 1600 Scotland, was the first country to adopt January 1 as the first day of the New Year. Now, many countries celebrate the New Year on 1st of January.
Polyethylene
Polyethylene (also called polyethene, usually shortened to PE) is a thermoplastic. It is used in consumer goods, typical examples are transport wraps, and garbage bags. Other uses include pre-fabricated plastic parts, plastic tubes, and insulation of electric cables. Plastic wrap is usually less adhesive than PVC, but this can be remedied by adding linear low-density polyethylene (LLDPE), which also increases the film's tensile strength. The world makes over 80 million tonnes of polyethylene per year.
Polyvinyl chloride
Polyvinyl chloride, also called Polychloroethene or PVC, is a thermoplastic. It turns soft when heated and hard when cooled. Polyvinyl chloride is made by polymerization of the monomer vinyl chloride (chloroethene) CH=CHCl. PVC can be made softer and more flexible by adding plasticizers. Phthalates are often used to soften PVC in this way.
Vinyl polymers are the most common type of plastic. "Vinyl" is actually Ethylene, a gas that is used to make those plastics including PVC. In popular usage, "vinyl" is often short for PVC, but there are two other vinyl polymers which are more common. The most common is polyethylene, the second-most common is polypropylene. Another, less used, is polystyrene.
Softened PVC is used in clothing, upholstery, electrical cable insulation, and other products instead of rubber. In the 1950s PVC became the usual material of phonograph records. Some audiophiles use the word "vinyl" to mean records made of PVC.
About half of the polyvinyl chloride resin manufactured each year is used to make pipes. PVC pipes are 66% of the newer water pipes in the US. PVC pipes are 75% of new sewer pipes. PVC is useful because of its light weight, high strength, and low reactivity. Also, PVC pipes can be glued together, or they can be connected by heating (similar to joining HDPE pipe). Both kinds of connections make permanent joints that do not leak.
PVC plastics can be recycled. Their recycling code is "3".
Polyamide
A polyamide is a polymer made of amides which are joined by peptide bonds. Examples for polyamides that occur naturally are proteins, such as wool and silk. It is also possible to artificially produce polyamides, one growth-step at a time. Examples for artificially-made polyamides are nylons, aramids and Sodium poly(aspartate).
Clarence Henry
Clarence Henry (b. March 27, 1926, d. February 28 1999) was an American heavyweight boxer. Contender for Rocky Marciano's title.
