Head

A head is the part of an organism, which usually comprises the eyes, ears, nose and mouth, each of which aid in various sensory functions, such as sight, hearing, smell, and taste. Some very simple animals may not have a head, but many bilaterally symmetric forms do. Heads develop in animals by an evolutionary trend known as cephalization. In bilaterally symmetrical animals, nervous tissues concentrate at the anterior region, forming structures responsible for information processing. Through biological evolution, sense organs and feeding structures also concentrate into the anterior region; these collectively form the head.

Human head

The human head is an anatomical unit that consists of the skull, hyoid bone and cervical vertebrae. The term "skull" collectively denotes the mandible (lower jaw bone) and the cranium (upper portion of the skull that houses the brain). The skull can also be described as being composed of the cranium, which encloses the cranial cavity, and the facial skeleton (includes the mandible). There are eight bones in the cranium and fourteen in the facial skeleton.

Head (watercraft)

The head (or heads) is a ship's toilet. The name derives from sailing ships in which the toilet area for the regular sailors was placed at the head or bow of the ship.

Design

In sailing ships, the toilet was placed in the bow for two reasons. Firstly, since most vessels of the era could not sail directly into the wind, the winds came mostly across the rear of the ship, placing the head essentially downwind. Secondly, if placed somewhat above the water line, vents or slots cut near the floor level would allow normal wave action to wash out the facility. Only the captain had a private toilet near his quarters, at the stern of the ship in the quarter gallery.

In many modern boats, the heads look similar to seated flush toilets but use a system of valves and pumps that brings sea water into the toilet and pumps the waste out through the hull in place of the more normal cistern and plumbing trap to a drain. In small boats the pump is often hand operated. The cleaning mechanism is easily blocked if too much toilet paper or other fibrous material is put down the pan.

News style

News style, journalistic style or news writing style is the prose style used for news reporting in media such as newspapers, radio and television.

News style encompasses not only vocabulary and sentence structure, but also the way in which stories present the information in terms of relative importance, tone, and intended audience. The tense used for news style articles is past tense.

News writing attempts to answer all the basic questions about any particular event—who, what, when, where and why (the Five Ws) and also often how—at the opening of the article. This form of structure is sometimes called the "inverted pyramid", to refer to the decreasing importance of information in subsequent paragraphs.

News stories also contain at least one of the following important characteristics relative to the intended audience: proximity, prominence, timeliness, human interest, oddity, or consequence.

The related term journalese is sometimes used, usually pejoratively, to refer to news-style writing. Another is headlinese.

Fix (position)

In position fixing navigation, a position fix (PF) or simply a fix is a position derived from measuring external reference points.

In nautical applications, the term is generally used with manual or visual techniques such as the use of intersecting visual or radio position lines rather than the use of more automated and accurate electronic methods such as GPS; in aviation, use of electronic navigation aids is more common. A visual fix can be made by using any sighting device with a bearing indicator. Two or more objects of known position are sighted, and the bearings recorded. Bearing lines are then plotted on a chart through the locations of the sighted items. The intersection of these lines is then the current position of the vessel.

Usually, a fix is where two or more position lines intersect at any given time. If three position lines can be obtained, the resulting "cocked hat", where the 3 lines do not intersect at the same point, but create a triangle where the vessel is inside, gives the navigator an indication of the accuracy in the three separate position lines.

ZAP (satellite television)

ZAP is a digital satellite television provider mainly for Portuguese speaking countries in sub-Saharan Africa. ZAP launched in Angola in 2010, providing a subscription based TV service covering the sub-Saharan countries to south of Angola. ZAP operates from the Eutelsat W7 satellite, placed over Africa at 36,0 degrees East, broadcasting in DVB-S2 in five K_u band transponders with MPEG-4 compression and Nagravision encryption.

ZAP provides an unprecedented number of Portuguese-language channels for a region where Portuguese-speaking African countries account for more than 40 million people.

In order to subscribe to ZAP's television service a subscriber can use either one of the two available decoders.
