High Speed Sync Flash 2. High-speed sync flash is used when you want to use a shutter speed that is faster than your camera’s native flash sync speed, or when you want to use a wider aperture setting that requires a higher shutter speed as is often the case with outdoor daylight shooting.he flash instantaneously lights up the subject (it does travel at the speed of light), so the flash doesn't last nearly as long as the shutter remains open even though this is very fast (1/60s, 1/125s 1/250s, etc.). There is a limit to the shutter speed, and this is the camera’s native sync.

Flash fire Flash fire. A flash fire is a sudden, intense fire caused by ignition of a mixture of air and a dispersed flammable substance such as a solid (including dust), flammable or combustible liquid (such as an aerosol or fine mist), or a flammable gas. It is characterized by high temperature, short duration, and a rapidly moving flame front. Contents.

- – Arc flash is fault current flowing through air between energized. phase conductors, phase conductors to neutral or ground. It results. in a rapid release of radiant (90%) and convection (10%) heat. energy from the break down of air insulation into a highly conductive.

Arc flash An electric arc between two nails. An arc flash (also called a flashover), which is distinctly different from the arc blast, is part of an arc fault, a type of electrical explosion or discharge that results from a low-impedance connection through air to ground or another voltage phase in an electrical system.

Eye health guide Corneal flash burns. The clear front of the eyes, called the cornea, can be damaged by over exposure to ultraviolet radiation from the sun and from other light sources, such as a welder’s arc or camera flash. These injuries are called corneal flash burns or ultraviolet keratitis, and is like a form of sunburn to the surface of the eye. Corneal flash burns can cause pain, changes in vision or loss of vision. Radiation damage to the cornea leading to a flash burn can be caused by ultraviolet light from various sources: Sunlamp in tanning salon. Reflection of the sun off the snow at high elevation (snow blindness) Photographer’s flood lamp. Lightning that strikes close to you.

What does HSS mean when it comes to drill bits? Adding molybdenum to steel increases the flexibility of the HSS bit. M-2 HSS, with a high molybdenum content, combines toughness and wear resistance with red hardness--the ability to hold a cutting edge even when red hot. M-2 is commonly used for tool dies, punches and high-production machining bits.

- The bottom line for me - supported by a trend of used oil analysis (UOA) performed by Predictive Services and Blackstone as well - is that Hot Shot's Secret (HSS) is very beneficial. My wear metals, already in the acceptable range, were reduced AND the additives, especially the molybdenum, improved.

Henoch-SchÃ¶nlein Purpura HSP is caused when a person's immune system doesn't fight an infection like it's supposed to. It occurs most often in the spring, usually after an upper respiratory infection, like a cold. HSP occurs most often in children from two to 11 years of age, but it can occur in anyone. Its exact cause is unknown. It might be triggered by bacterial or viral infections, medicines, insect bites, vaccinations or exposure to chemicals or cold weather.

- “Arc flash” is the extremely high-temperature discharge produced by an electrical fault in air. “Arc blast” is a high-pressure sound wave caused by a sudden arc fault.

Discuss Why Animal Eyes Glow Green When Illuminated at Night. What Causes âRed â Eyeâ in Flash Pictures? Because the light of the flash occurs too fast for the pupil to close, much of the very bright light from the flash passes into the eye through the pupil, reflects off the fundus at the back of the eyeball, and out through the pupil.

- Categories can increase the further into your electrical. distribution system and farther away you are from the. power source. The severity of a potential Arc-Flash. depends on the available fault current where the Arc-. Flash occurs and the opening time of the upstream. overcurrent protective devices. Because of the. impedance of cables or bus ducts, etc., the maximum. available fault current decreases the farther away. you are from the power source.

- Not all electrical systems harbor the danger of arc flash and arc blast, but many do. While it may be obvious to some of your students that the small-scale electrical and electronic circuits they will be building in your course pose no threat of arc flash or arc blast, it is important to reassure the others that this is a hazard almost impossible to exist in a classroom environment.

- The hazards of arc flash and arc blast are quite similar to the hazards faced by professional firefighters in their jobs, hence the similarity in protective equipment. Question 8 Arc flash may occur when using a voltmeter to measure voltage in a 480 volt electrical system, if there happens to be a power line transient (from a lightning strike, perhaps) at that time.

Flash flood warning A flash flood warning (SAME code: FFW) is issued when a flash flood is imminent or occurring in the warned area. A flash flood is a sudden, violent flood after a heavy rain, or occasionally after a dam break. Rainfall intensity and duration, topography, soil conditions, and ground cover contribute to flash flooding. Most flash floods occur when there is a heavy amount of precipitation falling in an area and that water is then channeled through streams or narrow gullies. Flash floods may take minutes or hours to develop. It is possible to experience a flash flood without witnessing any rain.

Eobard Thawne (New Earth) The Deadly Secret of the Flash/The Thousand-Year Separation! Scientists in Zoom's era discovered a deadly form of energy known as cosma-spurs. When he learned of them, he knew he had to return to the 20th century to use them on his foe, the Flash. This he did by creating a system of tornadoes laced with cosma-spur radiation which threatened to destroy Central City.

Hepatorenal Syndrome Hepatorenal syndrome (HRS) is a type of progressive kidney failure. As the kidneys stop functioning, toxins begin to build up in the body. Eventually, this leads to liver failure.It is only seen in people with severe liver damage and is almost always caused by cirrhosis.reventing Hepatorenal Syndrome. The only certain way to prevent HRS is to keep your liver healthy. To reduce your risk of developing cirrhosis, avoid drinking excessive amounts of alcohol. You should also try to avoid contracting hepatitis. Hepatitis A and B can be prevented by vaccination.

Flash point The flash point of a volatile material is the lowest temperature at which vapours of the material will ignite, when given an ignition source. The flash point may sometimes be confused with the autoignition temperature, which is the temperature at which the vapor ignites spontaneously without an ignition source. The fire point is the lowest temperature at which vapors of the material will keep burning after being ignited and the ignition source removed. The fire point is higher than the flash poi

"What does the red ""SRS"" light mean on the Honda Accord?" SRS stands for supplemental restraint system, which is your car's airbags. When the red SRS light comes on, it means that your airbags aren't working. Usually, when you start your car, that light will flash for about five seconds then turn off, signaling the airbags are properly working.
