School

A school is an institution designed for the teaching of students (or "pupils") under the direction of teachers. Most countries have systems of formal education, which is commonly compulsory. In these systems, students progress through a series of schools. The names for these schools vary by country (discussed in the Regional section below) but generally include primary school for young children and secondary school for teenagers who have completed primary education. An institution where higher education is taught, is commonly called a university college or university.

In addition to these core schools, students in a given country may also attend schools before and after primary and secondary education. Kindergarten or pre-school provide some schooling to very young children (typically ages 3–5). University, vocational school, college or seminary may be available after secondary school. A school may also be dedicated to one particular field, such as a school of economics or a school of dance. Alternative schools may provide nontraditional curriculum and methods.

School (TV series)

School!! (スクール!!, Sukūru!!) is a Japanese television series which premiered on Fuji TV on January 16, 2011. It was aired on Fuji TV's Sunday 9:00pm slot "Dramatic Sunday" in the 2011 winter drama season.

Plot

The story is about Shingū Elementary School which is beset by a lot of problems. Seichiro Naruse, a construction worker whose company closed down, suddenly becomes the principal of his old school. He must save the school from closing down.

Cast

Main Cast

The construction company he was working in went bankrupt and he was appointed as the civilian principal of the Shingū Elementary School. Having devoted 20 years in the construction industry, he has no teaching license. He takes up the job in order to keep a promise he made with his former teacher and ex-principal Takeichi. Nonetheless, he has a cheerful personality and takes positive action at every turn, and he frequently describes himself as a "X X demon". He was greatly appalled by the appearance and the change in his alma mater, which was struggling to change the status quo. In the last episode, Shingū Elementary School narrowly avoided closing down, but at the same time, he resigned to take responsibility for the incident that was caused by Akira Hara in the school.

Bleach (Nirvana album)

Bleach is the debut studio album by American rock band Nirvana, released on June 15, 1989 by Sub Pop. The main recording sessions took place at Reciprocal Recording in Seattle, Washington between December 1988 and January 1989.

Bleach was well received by critics, but failed to chart in the U.S. upon its original release. The album was re-released internationally by Geffen Records in 1992 following the success of Nirvana's second album, Nevermind (1991). The re-release debuted at number 89 on the Billboard 200, and peaked at number 33 on the UK Albums Chart and 34 on the Australian albums chart. In 2009 Sub Pop released a 20th anniversary edition of Bleach featuring a live recording of a Nirvana show in Portland, Oregon from 1990 as extra material. Since its release in 1989, Bleach has sold over 1.7 million units in the United States alone. It is Sub Pop's best-selling release to date.

Recording

Following the release of its debut single "Love Buzz" on Sub Pop in November 1988, Nirvana practiced for two to three weeks in preparation for recording a full-length album, even though Sub Pop had only requested an EP. The main sessions for Bleach took place at Reciprocal Recording Studios in Seattle, with local producer Jack Endino.

R-value (insulation)

The R-value is a measure of thermal resistance used in the building and construction industry. Under uniform conditions it is the ratio of the temperature difference across an insulator and the heat flux (heat transfer per unit area per unit time, ) through it or . Thermal resistance varies with temperature but it is common practice in construction to treat it as a constant value.

An R-value is a unit of thermal resistance for a particular material or assembly of materials (such as an insulation panel). The R-value depends on a solid material's resistance to conductive heat transfer. For loose or porous material, the R-value accounts for convective and radiative heat transfer through the material. However it does not account for the radiative or convective properties of the material's surface, which may be an important factor for some applications.

R is expressed as the thickness of the material normalized to the thermal conductivity. The unit thermal conductance of a material is the reciprocal of the unit thermal resistance. This can also be called the unit surface conductance. The higher the value of R, the better the building insulation's theoretical effectiveness.
