Flag

A flag is a piece of fabric (most often rectangular or quadrilateral) with a distinctive design that is used as a symbol, as a signaling device, or as decoration. The term flag is also used to refer to the graphic design employed, and flags have since evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is similarly challenging (such as the maritime environment where semaphore is used). National flags are potent patriotic symbols with varied wide-ranging interpretations, often including strong military associations due to their original and ongoing military uses. Flags are also used in messaging, advertising, or for other decorative purposes. The study of flags is known as vexillology, from the Latin word vexillum, meaning flag or banner.

Due to the use of flags by military units, "flag" is also used as the name of some military units. A flag (Arabic: لواء) is equivalent to a brigade in Arab countries, and in Spain, a flag (Spanish: bandera) is a battalion-equivalent in the Spanish Legion.

Biology

Flag is the common name of several genera or species of flowering plants:

Flag (lighting)

A flag is a device used in lighting for motion picture and still photography to block light. It can be used to cast a shadow, provide negative fill, or protect the lens from a flare. Its usage is generally dictated by the director of photography, but the responsibility for placing them can vary by region, usually devolving to either the gaffer and electricians or the key grip and lighting grips.

Flags come in a wide variety of shapes and sizes, from mere square inches ("dots and fingers") to many square feet ("meat axes"). Most "industry-standard" flags consist of a square wire frame stitched with black duvetyne, which minimizes any reflected light and keeps the flag lightweight. Flags are distinguished from larger light-cutting tools such as overhead rigs or butterflies in that they can be mounted on individual C-stands, as opposed to being affixed to collapsible frames.

The above notwithstanding, given smaller budgets or extenuating circumstances, virtually any opaque object can be used to flag light.

Head shot

A head shot or headshot is a specific type of portrait (usually a photograph) that realistically demonstrates a person's appearance for branding or casting. Many head shots are promotional pictures of actors, models, authors. Headshots could be a portrait of a face or full body with a background that clearly illustrate the personality inside the person photographed.

Identification

Head shot photographs are most commonly used in "about us" pages and many people represent themselves using head shots in social media. Other usage include online dating profile pictures. Actors often have a printed head shot with an attached résumé for auditions or an online presence in a casting workbook. Head shots are typically medium close-up (MCU)photographs which show the top of the shoulders up to above the head. In a typical head shot the eyes will be in the top, middle half of the photo according to the rule of thirds.

Entertainment industry

In theater, film, and television, actors, models, singers, and other entertainers are often required to include a head shot, along with their résumé, when applying for a job. These head shots are usually more artistic: they intend to portray the subject in the best possible light. Head shots often feature the actor or actress facing off-center. A performer will often have head shots expressing different poses and expressions to give a potential employer an idea of the subject's range of appearances or expressions. These types of head shots are called "looks". It is common for an actor to have different head shots for different roles, but for the most part these consist of a change in attire. The head shots that include a person’s shoulders are called "three-quarter" shots. Previously, head shots were often in black-and-white; however, most head shots are now taken in color.

Headshot (film)

Headshot (Thai: ฝนตกขึ้นฟ้า), is a 2011 Thai thriller film directed by Pen-Ek Ratanaruang. It screened at the 2012 San Diego Asian Film Festival Spring Showcase as well as the 2012 Los Angeles Asian Pacific Film Festival. The film was selected as the Thai entry for the Best Foreign Language Oscar at the 85th Academy Awards, but it did not make the final shortlist.

Plot

A cop-turned-hitman is struck in the head by a bullet and now sees the world upside down.

Combustion

Combustion /kəmˈbʌs.tʃən/ or burning is a high-temperature exothermic redox chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. Combustion in a fire produces a flame, and the heat produced can make combustion self-sustaining. Combustion is often a complicated sequence of elementary radical reactions. Solid fuels, such as wood, first undergo endothermic pyrolysis to produce gaseous fuels whose combustion then supplies the heat required to produce more of them. Combustion is often hot enough that light in the form of either glowing or a flame is produced. A simple example can be seen in the combustion of hydrogen and oxygen into water vapor, a reaction commonly used to fuel rocket engines. This reaction releases 242 kJ/mol of heat and reduces the enthalpy accordingly (at constant temperature and pressure):

Combustion of an organic fuel in air is always exothermic because the double bond in O₂ is much weaker than other double bonds or pairs of single bonds, and therefore the formation of the stronger bonds in the combustion products CO₂ and H₂O results in the release of energy. The bond energies in the fuel play only a minor role, since they are similar to those in the combustion products; e.g., the sum of the bond energies of CH₄ is nearly the same as that of CO₂. The heat of combustion is approximately -418 kJ per mole of O₂ used up in the combustion reaction, and can be estimated from the elemental composition of the fuel.

Burning (short story)

"Burning" is a short story by Orson Scott Card. It only appears in his short story collection Capitol.

Plot summary

Captain Homer Worthing and a fleet of twenty ship all piloted by telepaths are orbiting a settled star system. They are on the run from the imperial fleet and trying to leave settled space. When they request permission to take on supplies so that that can leave, the planetary authorities refuse. By the time the imperial fleet arrives they are nearly out of fuel and unable to fight the fleet or force their way down to the planets except by destroying one of them with a fusion bomb. Captain Homer refuses to consider this but when some of the ships run out of fuel he is removed from command and a threat is made to blow up one of the planets. No one believes they will do it and the imperial fleet attacks. After a second battle with the fleet one of the captains launches bombs at the planets but they are intercepted by Captain Homer. When a final volley of missiles is fired at Captain Homer’s ship he launches fusion bombs at all three planets in anger. Captain Homer immediately regrets his decision, but his ship is destroyed by missiles just as he is about to abort the bombs. When the fleet gets back to Capitol the commanders get medals and almost a hundred thousand telepaths are murdered.
