Pit prop

A pit prop or mine prop (British and American usage, respectively) is a length of lumber used to prop up the roofs of tunnels in coal mines.

Canada traditionally supplied pit props to the British market. As coal mining declined in importance and metal supports were used, the term became infrequently used.

Though it was merely a log cut to a particular length, it was classified as a finished product and so got around the extra Canadian tariffs on the export of raw lumber.

Because of the large quantities exported, it is probable many ended up in British pulp mills.

Most pit props were made from the wood of spruce trees.

The cell wall is not totally complete around the cell.It is interrupted by narrow pores carrying fine strands of cytoplasm,which interlink the contents of the cells.They are called PLASMODESMATA. They form a protoplasmic continuum called SYMPLAST. It consists of a canal, lined by plasmamembrane. It has a simple or branched tub le knows as DESMOTUBLE. DESMOTUBLE is an extension of endoplasmic reticulum. Plasmodesmata serves as a passage for many substances to pass through.It is also believed that they have a role in the relay of stimuli.

Arizona Proposition 102 (2008)

Arizona Proposition 102 was an amendment to the constitution of the state of Arizona adopted by a ballot measure held in 2008. It added Article 30 of the Arizona Constitution, which says:"Only a union of one man and one woman shall be valid or recognized as a marriage in this state.". The amendment added a constitutional ban on same-sex marriage to existing statutory bans in place since 1996. In October 2014, Article 30 of the Arizona Constitution was struck down as unconstitutional in the United States District Court for the District of Arizona, and is no longer enforced by the state of Arizona, which now allows and recognizes same-sex marriages.

Overview

On August 26, 2008, Arizona Attorney General Terry Goddard and Secretary of State Jan Brewer agreed that the ballot description would state that same-sex marriage was already prohibited by statute. Incorporating the same provision into the Arizona Constitution was meant to prevent an Arizona court from ruling that the statute was invalid under the Arizona Constitution.

PROP1

Homeobox protein prophet of PIT-1 is a protein that in humans is encoded by the PROP1 gene.

PROP1 has both DNA-binding and transcriptional activation ability. Its expression leads to ontogenesis of pituitary gonadotropes, as well as somatotropes, lactotropes, and caudomedial thyrotropes. Inactivating mutations in PROP1 result in deficiencies of luteinizing hormone (LH; MIM 152780), follicle-stimulating hormone (FSH; MIM 136530), growth hormone (GH; MIM 139250), prolactin (PRL; MIM 176760), and thyroid-stimulating hormone (TSH; MIM 188540). See combined pituitary hormone deficiency (CPHD; MIM 262600).[supplied by OMIM]
