  1. Electronic Air Suspension

    Electronic Air Suspension is the name of the air suspension system installed on the second version of the Range Rover , known as the Range Rover P38A . Overview The EAS provides variable height suspension for on and off road applications Components The system comprises a vulcanised rubber air spring at each wheel an air compressor , located under the Hood vehicle bonnet a compressed air storage tank, storing air at 150psi 1000 kpa a valve block which routes air from the storage tank to the four air springs via a series of solenoids , valves and many o rings an EAS computer which communicates with the car s main computer the Body Electronic Computer Module BeCM and decides where to route air pressure a series of 6mm air pipe which channels air throughout the system mainly from the storage tank to the air springs via the valve block an air drier canister containing desiccant Advantages The air springs were designed to provide a luxurious ride quality and provide the ability to raise the body of the vehicle for off road clearance and lower the vehicle when driving at higher speeds on highways. Problems The EAS computer is regarded by some to be unintelligent. It can, using pre programmed criteria to detect a fault, disable the system into Hard Fault Mode which can lower the vehicle to the suspension bump stops and force the owner to limp to the dealership for inspection and repair. Many enthusiasts use diagnostic devices such as laptop computers running specially developed freeware software and hand held computers to clear the spurious faults and avoid the trip to the dealer. Many enthusiasts share information about DIY repairs of the EAS on webpages and online forums. Category Land Rover vehicles ...   more details

The resulting powder has an extremely low bulk density and high surface area. Its three dimensional structure results in viscosity increasing, thixotropic behavior when used as a thickener or reinforcing filler. Properties Fumed silica has a very strong thickening effect. Primary particle size is 5 50  nm. The particles are non porous and have a surface area of 50 600 m sup 2 sup g. Density 160 190kg m sup 3 sup .

  1. Hydrated silica

    Hydrated silica is a form of silicon dioxide , which has a variable amount of water in the formula. It is also known as silicic acid , a term usually used for its form dissolved in water. It is found in nature, as opal , which has been mined as a gemstone for centuries and in the cell walls of diatoms . It is also manufactured for use in toothpaste . Once dehydrated the gel is used as a desiccant known as Silica gel . It is also used in various paints and varnishes and in the production of beer .

  1. List of enemy Monomakias

    In the anime series and manga Brigadoon Marin & Melan , Monomakias are bionic weapons from the world called Brigadoon that come down from the sky to try to bring Marin, the protagonist, back to Brigadoon with them. This is an unofficial listing of enemy Monomakias shown in the anime series. Dollon A Murder Monomakia, and the first one that Marin encountered on the day Brigadoon first appeared. Resembling a Daruma doll , Dollon could fly, spins at high speeds and has four different eyes, each with a different function. Melan defeated Dollon by slicing off the crown of its head. Bronte type Monomakias Named Proton, Deuteron, and Triton. Appeared from the strange object called the Tower of Bronte that fell into Tokyo Bay . When the three fly in triangle formation, they were able to generate a very powerful energy field which they used to paralyze their victims. They were also able to produce enough electrical energy to overload light bulbs and illuminate Tokyo Tower . All three were defeated by Melan. Hyudol A liquid Monomakia that was also inside the Tower of Bronte. At first it was only a small pink blob and went unnoticed for several days. It grew bigger and stronger by consuming animals and even a zoo keeper at the Ueno Zoo . By the time it got to Marin at Shinobazu Pond it had grown into a huge, watery elephant like form with wings allowing it to fly through the air. When Melan explained to Marin that the only way to kill it was dehydrating it, she had him lure it to a plant that produced desiccant . It was killed when Melan buried it under a huge pile of desiccant. Nepon A sniper Monomakia that looked like a pink snail. Many of them were sent to Earth but they all landed in a sake brewery and dissolved in the alcohol. The lone survivor got in three attempted shots at Marin. The first was aborted when she moved out of range, the second helped her escape from the police, and the third of which failed. Never even got to fight Melan, as he dissolved when Tadashi acci ...   more details



  1. Pyranometer

    File Hukseflux radiometer sr11 photo.jpg thumb right A solar radiation sensor that can be applied in scientific grade solar radiation observations. It complies with the first class specifications within the latest ISO and WMO standards. The scientific name of this instrument is pyranometer. A pyranometer is a type of actinometer used to measure broadband solar irradiance on a planar surface and is a sensor that is designed to measure the solar radiation flux density in watts per metre square from a field of view of 180 degrees. The name pyranometer stems from Greek, pyr meaning fire and ano meaning above, sky . A typical pyranometer does not require any power to operate. Explanation The solar radiation spectrum extends approximately from 300 to 2,800 nm. Pyranometers usually cover that spectrum with a spectral sensitivity that is as flat as possible. To make a measurement of irradiance , it is required by definition that the response to beam radiation varies with the cosine of the angle of incidence, so that there will be a full response when the solar radiation hits the sensor perpendicularly normal to the surface, sun at zenith, 0 degrees angle of incidence , zero response when the sun is at the horizon 90 degrees angle of incidence, 90 degrees zenith angle , and 0.5 at 60 degrees angle of incidence. It follows that a pyranometer should have a so called directional response or cosine response that is close to the ideal cosine characteristic.

  1. Kulen

    Image Kulin serviran .jpg thumb right Slices of kulen File Kulin prije susenja .jpg right thumb Kulen before smoking from Slavonia Kulen Serbian Cyrillic is a type of flavored sausage made of minced pork that is traditionally produced in Croatia Slavonia and Serbia Vojvodina , and its designation of origin has been protected in Croatia. In parts of Slavonia, kulen is called kulin in Ikavian accent . The meat is low fat, rather brittle and dense, and the flavor is spicy. The red paprika gives it aroma and color, and garlic adds spice. The original kulen recipe does not contain black pepper because its hot flavor comes from hot red paprika. The traditional time of producing kulen is during the pig slaughter done every autumn by most rural households. Kulen matures during the winter it can be eaten at this time, although not fully dried and cured yet, with very hot taste, but it will develop its full taste by the following summer. To produce a dryer, firmer kulen, it is sometimes kept buried under ashes, which act as a desiccant . Kulen is a shelf stable meat product, with a shelf life of up to two years when refrigerated or even kept at room temperatures. The meat is stuffed and pressed into bags made of pork intestine, and formed into links that are usually around ten centimetres in diameter, and up to three times as long, weighing around a kilogram. The pieces of kulen are smoking food smoked for several months, using certain types of wood. After the smoking they are air dried for another several months. This process can last up to a year. Although similar to other air dried procedures, the meat is fermented in addition to the air drying. High grade kulen is sometimes even covered with a thin layer of mould, giving it a distinct aroma. When the kulen meat is stuffed into the small intestine, it is thinner and requires less smoking and drying, but it also takes less time to prepare. This type of sausage is often referred to as kulenova seka literally kulen s si ...   more details
