Cell growth

The term cell growth is used in the contexts of cell development and cell division (reproduction). When used in the context of cell division, it refers to growth of cell populations, where a cell, known as the "mother cell", grows and divides to produce two "daughter cells" (M phase). When used in the context of cell development, the term refers to increase in cytoplasmic and organelle volume (G1 phase), as well as increase in genetic material (G2 phase) following the replication during S phase.

Cell populations

Cell populations go through a particular type of exponential growth called doubling. Thus, each generation of cells should be twice as numerous as the previous generation. However, the number of generations only gives a maximum figure as not all cells survive in each generation.

Cell size

Yeast cell size regulation

The relationship between cell size and cell division has been extensively studied in yeast. For some cells, there is a mechanism by which cell division is not initiated until a cell has reached a certain size. If the nutrient supply is restricted (after time t = 2 in the diagram, below), and the rate of increase in cell size is slowed, the time period between cell divisions is increased. Yeast cell-size mutants were isolated that begin cell division before reaching a normal/regular size (wee mutants).

Standing Stone (album)

Standing Stone is Paul McCartney's second full-length release of original classical music (coming after 1991's Liverpool Oratorio) and was issued shortly after Flaming Pie's release in 1997. The world premiere performance was held at The Royal Albert Hall on 14 October 1997.

History

Following up on 1991's Paul McCartney's Liverpool Oratorio, the Standing Stone project was composed out of a long poem McCartney authored and was performed by the London Symphony Orchestra and conducted by Lawrence Foster at EMI's Abbey Road Studios. Unlike Liverpool Oratorio, this new project is not an operatic performance of a story, but an instrumental one, though it employs the use of a choir.

The cover for the album is actually one of the many photos taken by Linda McCartney during late 1969/early 1970 that would initially be seen on the inside gatefold cover of Paul's first album McCartney. Incidentally, this project was her husband's last release before Linda died of breast cancer on 17 April 1998, having been diagnosed almost three years earlier.
