Heading (metalworking)
Heading is a metalworking process which incorporates the forging Forging is a manufacturing process involving the shaping of metal using localized compression (physics), compressive forces. The blows are delivered with a hammer (often a power hammer) or a die (manufacturing), die. Forging is often classif ..., extruding and upsetting process. It is often performed in the cold state, resulting in cold working. This process typically produces a near net shape workpiece, which means the final product is almost finished although it can sometimes create the final product less plating or heat treating. An important consideration in heading is the tendency for the wire to buckle if its unsupported length to diameter ratio is too high. This ratio usually is limited to less than 3:1 but with appropriate dies, it can be higher. There are a variety of cold heading machines but typically for fastener manufacturing you will see one die two blow up to five die six blow and beyond. ...

Heading (navigation)
In navigation, the heading of a vessel or aircraft is the compass direction in which the craft's bow or nose is pointed. Note that the heading may not necessarily be the direction that the vehicle actually travels, which is known as its '' course''. Any difference between the heading and course is due to the motion of the underlying medium, the air or water, or other effects like skidding or slipping. The difference is known as the ''drift'', and can be determined by the ''wind triangle''. At least seven ways to measure the heading of a vehicle have been described. Heading is typically based on cardinal directions, so 0° (or 360°) indicates a direction toward true north, 90° true east, 180° true south, and 270° true west. TVMDC TVMDC,AW is a mnemonic for converting from true heading, to magnetic and compass headings. TVMDC is a mnemonic initialism for true heading, variation, magnetic heading, deviation, compass heading, add westerly. The most common use of the TVMDC met ...

Double-heading
In railroad terminology, double heading indicates the use of two locomotives at the front of a train, each operated individually by its own crew. The practice of triple-heading involves the use of three locomotives. The practice of multi-heading involves the use of multiple locomotives and so on. Double heading is most common with steam locomotives, but is also practised with diesel locomotives. It is not strictly the same practice as two or more diesel or electric locomotives working 'Multiple-unit train control, in multiple' (or 'multiple-working'), where both (or all) locomotives are controlled by a single driver in the cab of the leading locomotive. Advantages Double heading is practised for a number of reasons: * In the UK it was usually to gain traction on steep inclines, twice the amount of driven wheels – twice the amount of grip. * The need for additional motive power when a single locomotive is unable to haul the train due to uphill grades, excessive train weight, ...

Subject Heading
In information retrieval, an index term (also known as subject term, subject heading, descriptor, or keyword) is a term that captures the essence of the topic of a document. Index terms make up a controlled vocabulary for use in bibliographic records. They are an integral part of bibliographic control, which is the function by which libraries collect, organize and disseminate documents. They are used as keywords to retrieve documents in an information system, for instance, a catalog or a search engine. A popular form of keywords on the web are tags, which are directly visible and can be assigned by non-experts. Index terms can consist of a word, phrase, or alphanumerical term. They are created by analyzing the document either manually with subject indexing or automatically with automatic indexing or more sophisticated methods of keyword extraction. Index terms can either come from a controlled vocabulary or be freely assigned. Keywords are stored in a search index. Common words ...

Headline
The headline is the text indicating the content or nature of the article below it, typically by providing a form of brief summary of its contents. The large type ''front page headline'' did not come into use until the late 19th century when increased competition between newspapers led to the use of attention-getting headlines. It is sometimes termed a news ''hed'', a deliberate misspelling that dates from production flow during hot type days, to notify the composing room that a written note from an editor concerned a headline and should not be set in type. Headlines in English often use a set of grammatical rules known as '' headlinese'', designed to meet stringent space requirements by, for example, leaving out forms of the verb "to be" and choosing short verbs like "eye" over longer synonyms like "consider". Production A headline's purpose is to quickly and briefly draw attention to the story. It is generally written by a copy editor, but may also be written by the writer, ...

New Zealand Heading Dog
The New Zealand Heading Dog is a New Zealand list of dog breeds, breed of working and herding dog derived from the Border Collie. The dogs are sturdy, long-legged and even-haired, and use their visual prowess, intelligence and quick movement to control sheep. They are generally black and white in colour, but may also be tan. History The New Zealand Heading Dog is descended from the Border Collie, a breed of dog originally from the Scottish border. Early settlers brought these dogs to New Zealand to herd sheep, then went on to breed more specified dogs. Due to the Border Collie's long hair, they were bred with shorter haired dogs to create a breed that was better suited to the hot summers of the local environment. They were also bred to have less of an instinct to lie down than a Border Collie, standing still on their feet to make them more visible to the shepherd at long distance in the native tussock grass, tussock, and to run longer distances, and in some lines to be larger a ...

Barley
Barley (), a member of the grass family, is a major cereal grain grown in temperate climates globally. It was one of the first cultivated grains; it was domesticated in the Fertile Crescent around 9000 BC, giving it nonshattering spikelets and making it much easier to harvest. Its use then spread throughout Eurasia by 2000 BC. Barley prefers relatively low temperatures and well-drained soil to grow. It is relatively tolerant of drought and soil salinity, but is less winter-hardy than wheat or rye. In 2023, barley was fourth among grains in quantity produced, 146 million tonnes, behind maize, rice, and wheat. Globally, 70% of barley production is used as animal feed, while 30% is used as a source of fermentable material for beer, or further distilled into whisky, and as a component of various foods. It is used in soups and stews and in barley bread of various cultures. Barley grains are commonly made into malt using a traditional and ancient method of preparatio ...
