Dock (maritime)

A dock (from Dutch dok) is either the area of water between or next to a human-made structure or group of structures involved in the handling of boats or ships, usually on or close to a shore, or the structures themselves. The exact meaning varies among different variants of the English language. "Dock" may also refer to a dockyard or shipyard where the loading, unloading, building, or repairing of ships occurs.

History

The earliest known docks were those discovered in Wadi al-Jarf, an ancient Egyptian harbor dating from 2500 BCE located on the Red Sea coast. Archaeologists also discovered anchors and storage jars near the site. A dock from Lothal in India dates from 2400 BCE and was located away from the main current to avoid deposition of silt. Modern oceanographers have observed that the Harappans must have possessed great knowledge relating to tides in order to build such a dock on the ever-shifting course of the Sabarmati, as well as exemplary hydrography and maritime engineering. This was the earliest known dock found in the world, equipped to berth and service ships. It is speculated that Lothal engineers studied tidal movements, and their effects on brick-built structures, since the walls are of kiln-burnt bricks. This knowledge also enabled them to select Lothal's location in the first place, as the Gulf of Khambhat has the highest tidal amplitude and ships can be sluiced through flow tides in the river estuary. The engineers built a trapezoidal structure, with north-south arms of average 21.8 metres (71.5 ft), and east-west arms of 37 metres (121 ft).

Rumex

The docks and sorrels, genus Rumex L., are a genus of about 200 species of annual, biennial and perennial herbs in the buckwheat family Polygonaceae.

Members of this family are very common perennial herbs growing mainly in the Northern Hemisphere, but various species have been introduced almost everywhere.

Some are nuisance weeds (and are sometimes called dockweed or dock weed), but some are grown for their edible leaves.

Rumex species are used as food plants by the larvae of a number of Lepidoptera species - see list of Lepidoptera that feed on Rumex.

Description

They are erect plants, usually with long taproots. The fleshy to leathery leaves form a basal rosette at the root. The basal leaves may be different from those near the inflorescence. They may or may not have stipules. There are minor leaf veins. The leaf blade margins are entire or crenate.

The usually inconspicuous flowers are carried above the leaves in clusters. The fertile flowers are mostly hermaphrodite, or they may be functionally male or female. The flowers and seeds grow on long clusters at the top of a stalk emerging from the basal rosette; in many species the flowers are green, but in some (such as sheep's sorrel, Rumex acetosella) the flowers and their stems may be brick-red. Each seed is a 3-sided achene, often with a round tubercle on one or all three sides.

Dock (OS X)

The Dock is a prominent feature of the graphical user interface of the OS X operating system. It is used to launch applications and to switch between running applications. The Dock is also a prominent feature of OS X's predecessor NeXTSTEP and OpenStep operating systems. The earliest known implementations of a dock are found in operating systems such as RISC OS and NeXTSTEP. iOS has its own version of the Dock for iPhone and iPad.

Apple applied for a US patent for the design of the Dock in 1999 and was granted the patent in October 2008, nine years later. Applications can be added to and removed from the Dock by drag and drop, except for the Finder, which is a permanent fixture as the leftmost item (or topmost if the Dock is configured to be vertical). The Trash icon is also a permanent fixture at the right end (or bottom if the Dock is repositioned). Part of the OS X Core Services, Dock.app is located at /System/Library/CoreServices/.

Overview

In NeXTSTEP and OpenStep, the Dock is an application launcher that holds icons for frequently used programs. The icon for the Workspace Manager and the Recycler are always visible. The Dock indicates if a program is not running by showing an ellipsis below its icon. If the program is running, there isn't an ellipsis on the icon. In OS X, running applications are identified by a blue luminous dot (a dark dot since OS X Yosemite).

Maritime

Maritime is primarily an adjective that describes objects or activities related to the sea.

Maritime or Maritimes as a noun may also refer to:

Geography

Music

Climate categories in viticulture

In viticulture, the climates of wine regions are categorised based on the overall characteristics of the area's climate during the growing season. While variations in macroclimate are acknowledged, the climates of most wine regions are categorised (somewhat loosely based on the Köppen climate classification) as being part of a Mediterranean (for example Tuscany), maritime (ex: Bordeaux) or continental climate (ex: Columbia Valley). The majority of the world's premium wine production takes place in one of these three climate categories in locations between the 30th parallel and 50th parallel in both the northern and southern hemisphere. While viticulture does exist in some tropical climates, most notably Brazil, the amount of quality wine production in those areas is so small that the climate effect has not been as extensively studied as other categories.

Influence of climate on viticulture

Beyond establishing whether or not viticulture can even be sustained in an area, the climatic influences of a particular area goes a long way in influencing the type of grape varieties grown in a region and the type of viticultural practices that will be used. The presence of adequate sun, heat and water are all vital to the healthy growth and development of grapevines during the growing season. Additionally, continuing research has shed more light on the influence of dormancy that occurs after harvest when the grapevine essentially shuts down and reserves its energy for the beginning of the next year's growing cycle.

Oceanic climate

An oceanic climate (also known as marine, west coast and maritime) is the climate typical of the west coasts at the middle latitudes of continents, and generally features warm (but not hot) summers and cool (but not cold) winters, with a relatively narrow annual temperature range. It typically lacks a dry season, as precipitation is more evenly dispersed throughout the year. It is the predominant climate type across much of Northern Western Europe, parts of the Appalachians, portions of southwestern South America and small areas of Africa, in southeast Australia, and New Zealand as well as isolated locations elsewhere.

Under the Köppen climate classification, the typical zone associated with the Oceanic climate is Cfb, although it includes subtropical highland zones not usually associated with marine climates. Often, parts of the Csb Mediterranean or Dry-Summer subtropical zones are not associated with a typical Mediterranean climate, and would be classified as Temperate Oceanic (Cfb), except dry-summer patterns meet Köppen's minimum Cs thresholds. Other climate classification systems, such as Trewartha climate classification, place these areas firmly in the Oceanic zone (Do).
