concentrate thickeners for scheelite high speed

  • common ostrich

    the common ostrich struthio camelus or simply ostrich, is a species of large flightless native to certain large areas of is one of two extant species of ostriches, the only living members of the genus struthio in the ratite order of birds. the other is the somali ostrich struthio molybdophanes , which was recognized as a distinct species by birdlife international in 2014 .

  • cathode-ray tube

    high vacuum inside glass-walled cathode-ray tubes permits electron beams to fly freely—without colliding into molecules of air or other gas. if the glass is damaged, atmospheric pressure can collapse the vacuum tube into dangerous fragments which accelerate inward and then spray at high speed in all directions.

  • cheetah

    the cheetah runs no more than 500 m 1,640 ft at the speed of 104 to 120 km/h 65 to 75 mph ; it very rarely runs at this high speed as most chases are within 100 m 330 ft . by 1973, cheetah sprinting distance was thought to be limited by the building up of excessive body heat.

  • gusen concentration camp

    gusen was a system of three concentration camps in an area west of mauthausen concentration camp that spread over the territories of the political communities langestein, sankt georgen an der gusen, luftenberg an der donau and katsdorf in the reichsgau ostmark currently perg district, upper austria .

  • andromeda galaxy

    the brighter concentration, designated as p1, is offset from the center of the galaxy. the dimmer concentration, p2, falls at the true center of the galaxy and contains a black hole measured at 3–5 × 10 7 m ☉ in 1993, and at 1.1–2.3 × 10 8 m ☉ in 2005. the velocity dispersion of material around it is measured to be ≈ 160 km/s 99 mi/s .

  • liquid crystal

    in 1969, hans kelker succeeded in synthesizing a substance that had a nematic phase at room temperature, mbba, which is one of the most popular subjects of liquid crystal research. the next step to commercialization of liquid-crystal displays was the synthesis of further chemically stable substances cyanobiphenyls with low melting temperatures by george gray.

  • physiology of underwater diving

    aortic hemoglobin concentration has been observed to rise in diving weddell seals. high hematocrit blood is stored in the large spleen of deep-diving seals, and may be released into the circulation during a dive, making the spleen an important oxygen reservoir for use during a dive, while reducing blood viscosity when the animal is breathing.

  • antenna radio

    the q of a narrow band antenna can be as high as 15. on the other hand, the reactance at the same off-resonant frequency of one using thick elements is much less, consequently resulting in a q as low as 5. these two antennas may perform equivalently at the resonant frequency, but the second antenna will perform over a bandwidth 3 times as wide .

  • m1 abrams

    the m1 abrams is a third-generation american main battle tank designed by chrysler defense now general dynamics land systems . conceived for modern WPCed ground warfare and now one of the heaviest tanks in service at nearly 68 short tons almost 62 metric tons , it introduced several innovative features, including a multifuel turbine engine, sophisticated chobham composite WPC, a computer .

  • ball lightning

    ball lightning vanishes thus by silent extinction when the available density of charged particles is too low, while it disappears with a loud and sometimes very violent explosion when this density is too high. electronic oscillations are also possible as stationary waves in a plasma ball or thick plasma membrane. this yields concentric luminous .

  • organic solar cell

    an organic solar cell osc or plastic solar cell is a type of photovoltaic that uses organic electronics, a branch of electronics that deals with conductive organic polymers or small organic molecules, for light absorption and charge transport to produce electricity from sunlight by the photovoltaic effect.most organic photovoltaic cells are polymer solar cells.

  • deicing fluid

    deicing fluids come in a variety of types, and are typically composed of ethylene glycol eg or propylene glycol pg , along with other ingredients such as thickening agents, surfactants wetting agents , corrosion inhibitors, colors, and uv-sensitive dye. propylene glycol-based fluid is more common because it is less toxic than ethylene glycol.

  • moon

    the moon is an astronomical body orbiting earth as its only natural is the fifth-largest satellite in the solar system, and by far the largest among planetary satellites relative to the size of the planet that it orbits its primary .the moon is, after jupiter's satellite io, the second-densest satellite in the solar system among those whose densities are known.

  • cheetah

    the cheetah's thin and light body makes it well-suited to short, explosive bursts of speed, rapid acceleration, and an ability to execute extreme changes in direction while moving at high speed. research has indicated that the cheetah's athleticism is critical to the cat's predatory success rate.

  • messerschmitt bf 109

    when the bf 109 was designed in 1934, by a team led by willy messerschmitt and robert lusser, its primary role was that of a high-speed, short range interceptor. it used the most advanced aerodynamics of the time and embodied advanced structural design which was ahead of its contemporaries.

  • spin coating

    usually a small amount of coating material is applied on the center of the substrate, which is either spinning at low speed or not spinning at all. the substrate is then rotated at high speed in order to spread the coating material by centrifugal force. a machine used for spin coating is called a spin coater, or simply spinner.

  • jasenovac concentration camp

    during and since world war ii, there has been much debate and controversy regarding the number of victims killed at the jasenovac concentration camp complex during its more than three-and-a-half years of operation. after the war, a figure of 700,000 reflected the 'conventional wisdom', although estimates have gone as high as 1.4 million.

  • national ignition facility

    the national ignition facility, located at lawrence livermore national laboratory.. the target assembly for nif's first integrated ignition experiment is mounted in the cryogenic target positioning system, or cryotarpos. the two triangle-shaped arms form a shroud around the cold target to protect it until they open five seconds before a shot.

  • ancient israelite cuisine

    ancient israelite cuisine refers to the food eaten by the ancient israelites during a period of over a thousand years, from the beginning of the israelite presence in the land of israel at the beginning of the iron age until the roman period.the dietary staples were bread, wine and olive oil or shemen used to make challah or 'cakes' , but also included legumes, fruits and vegetables, dairy .
