Journal

A journal (through French from Latin diurnalis, daily) has several related meanings:

The word "journalist", for one whose business is writing for the public press and nowadays also other media, has been in use since the end of the 17th century.

The Journal (newspaper)

The Journal is a daily newspaper produced in Newcastle upon Tyne. Published by ncjMedia, (a division of Trinity Mirror), The Journal is produced every weekday and Saturday morning and is complemented by its sister publications the Evening Chronicle and the Sunday Sun.

The newspaper mainly has a middle-class and professional readership throughout North East England, covering a mixture of regional, national and international news. It also has a daily business section and sports page as well as the monthly Culture magazine and weekly property supplement Homemaker.

News coverage about farming is also an important part of the paper with a high readership in rural Northumberland.

It was the named sponsor of Tyne Theatre on Westgate Road during the 2000s, until January 2012.

The first edition of the Newcastle Journal was printed on 12 May 1832, and subsequent Saturdays, by Hernaman and Perring, 69 Pilgrim Street, Newcastle. On 12 May 2007, The Journal celebrated its 175th Anniversary and 49,584th issue.

Wear

Wear is related to interactions between surfaces and specifically the removal and deformation of material on a surface as a result of mechanical action of the opposite surface.

In materials science, wear is erosion or sideways displacement of material from its "derivative" and original position on a solid surface performed by the action of another surface.

Wear of metals occurs by the plastic displacement of surface and near-surface material and by the detachment of particles that form wear debris. This process may occur by contact with other metals, nonmetallic solids, flowing liquids, or solid particles or liquid droplets entrained in flowing gasses.

Wear can also be defined as a process where interaction between two surfaces or bounding faces of solids within the working environment results in dimensional loss of one solid, with or without any actual decoupling and loss of material. Aspects of the working environment which affect wear include loads and features such as unidirectional sliding, reciprocating, rolling, and impact loads, speed, temperature, but also different types of counter-bodies such as solid, liquid or gas and type of contact ranging between single phase or multiphase, in which the last multiphase may combine liquid with solid particles and gas bubbles.

Jibe

A jibe (US) or gybe (Britain) is a sailing maneuver whereby a sailing vessel reaching downwind turns its stern through the wind, such that the wind direction changes from one side of the boat to the other. For square-rigged ships, this maneuver is called wearing ship.

In this maneuver, the mainsail will cross the center of the boat while the jib is pulled to the other side of the boat. If the spinnaker is up, the pole will have to be manually moved to the other side, to remain opposite the mainsail. In a dinghy, raising the centerboard can increase the risk of capsizing during what can be a somewhat violent maneuver, although the opposite is true of a dinghy with a flat, planing hull profile: raising the centerboard reduces heeling moment during the manouevre and so reduces the risk of capsize.

The other way to change the side of the boat that faces the wind is turning the bow of the boat into, and then through, the direction of the wind. This operation is known as tacking or coming about. Tacking more than 180° to avoid a jibe is sometimes referred to as a 'chicken jibe'.
