Nature, "Dust-free quasars in the early Universe", Linhua Jiang, Xiaohui Fan, W. N. Brandt, Chris L. Carilli, Eiichi Egami1, Dean C. Hines, Jaron D. Kurk, Gordon T. Richards, Yue Shen, Michael A. Strauss, Marianne Vestergaard, Fabian Walter, 18 March 2010, vol.464, pp.380–383, , , (accessed 6 April 2010) QSO J0005-0006 was found to be dust free in a 2006 study of distant quasars, and confirmed as such in the 2010 study. The 2010 study removed the potential of masking the dust emission signature occurring, by studying the amount of obscuration of the quasar.

Second, Funk tested various treatments to reduce dust and increase traction for the drivers. He started with mineral oil, then branched out into various other substances, which would result in a track "not only relatively dust free but pavement fast." This work brought the attention of highway engineers, who made the track a proving ground for roadbuilding technology.

This varying grain angle limits some of the tools that may be used and requires additional skill from the turner. Moisture content affects both the ease of cutting wood and the final shape of the work when it dries. Wetter wood cuts easily with a continuous ribbon of shavings that are relatively dust-free. However, the wet wood moves as it dries.

The rock was selected as Spirits first target because its dust-free, flat surface was ideally suited for grinding. Clean surfaces also are better for examining a rock's top coating. Spirit also returned microscopic images and Mössbauer spectrometer readings of Adirondack taken the day before the rover developed computer and communication problems on January 22, 2004. Both are unprecedented investigations of any rock on another planet.

8mm tapes should be stored vertically, out of direct sunlight, in a dry, cool, dust-free environment. As with any media, they will eventually deteriorate and lose their recorded contents over time, resulting in a buildup of image noise and dropouts. Tapes more than 15 years old may start to show signs of degradation. Among other problems, they can become sticky, jamming playback units, or become brittle and snap.

If significant laser power is coupled into the fibre, the dust particles will scatter light in the evanescent field, heat up, and may thermally destroy the waist. In order to prevent this, SDFs are pulled and used in dust-free environments such as flowboxes or vacuum chambers. For some applications, it is useful to immerse the freshly tapered SDF into purified water and thus prevent the waist from contamination.

It was spent for the fixation of a modern central air conditioning plant for the building. It had an added advantage of the provision of a dust free environment. The constant temperature was needed for the fine functioning of many pieces of equipment and the conditions needed for the performance of sophisticated tests. During those days, the pressing demands of quality pathology service had compelled the AFIP to assume the role of a Central Reference Laboratory.

Ram pressure stripping in NGC 4402 as it falls towards the Virgo Supercluster (off image, toward bottom left). Note the dust (brown) trailing behind (toward upper right) the galaxy, versus the dust-free (blue-white) leading edge. In physics, ram pressure is a pressure exerted on a body moving through a fluid medium, caused by relative bulk motion of the fluid rather than random thermal motion. It causes a drag force to be exerted on the body.

It produced its own electricity that ran all the electric motors throughout the plant facilities. The main building was constructed with reinforced concrete of the Kahn System invented and patented by Julius Kahn in 1902. The factory was placed in a location where a dust free environment was given priority. Disagreements arose between Rath and Bachner as to how the Manistee Watch Company should be run. Rath bought out Bachner's share of the business in a payment contract in 1910.

A thin membrane surface (TMS) is an oil-treated aggregate which is laid down upon a gravel road bed, producing a dust-free road. A TMS road reduces mud problems and provides stone-free roads for local residents where loaded truck traffic is negligible. The TMS layer adds no significant structural strength, and so is used on secondary highways with low traffic volume and minimal weight loading. Construction involves minimal subgrade preparation, following by covering with a cold mix asphalt aggregate.

However, this number has increased to 11 in 2000s. In 1960s and 1970s, each decade had 3 years that were Asian-dust free. However, starting from 2000s, there has not been a single year without Asian dust. In just four months of 2018, Gyeonggi Province of South Korea issued 42 dust warnings and advisories, which has increased from 36 in the same period in 2017. This reflects the increase in average dust concentration level from 132.88 parts per million (ppm) in 2017 to 149 ppm in 2018.

However, this can often be expensive and is not a very good Environmentally friendly alternative. Cement fly ash, lime fly ash (separately, or with cement or lime), bitumen, tar, cement kiln dust (CKD), tree resin and ionic stabilizers are all commonly used stabilizing agents. Other stabilization techniques include using on-site materials including sub-soils, sands, mining waste, natural stone industry waste and crushed construction waste to provide stable, dust free local roads for complete dust control and soil stabilization. There are advantages and disadvantages to many of these soil stabilizers.

Action Southwest, Area Transportation Planning Council (ATPC), Department of Highways, Highway 37 partnership and Highway 32 partnership came together to resolve the transportation problems and it was decided to undertake Action Southwest has appointed a transportation study steering committee as well as two consulting firms to monitor progress. "Thin-membrane" highways are secondary routes providing a dust-free surface, but were never engineered for heavy truck traffic. Heavy trucks need to be rerouted to refurbished routes designed for truck traffice said Highways Minister Eldon Lautermilch. Saskatchewan comprises of thin-membrane highway.

In contrast, the only comparable events on Earth are infrequent large volcanic eruptions such as Krakatoa which threw large amounts of ash into the atmosphere in 1883, causing a global temperature drop of around 1 °C (2 °F). Perhaps more importantly, these storms affect electricity production from solar panels for long periods, as well interfering with communications with Earth. Mars has no rain and virtually no clouds, so although cold, it is permanently sunny (apart from during dust storms). This means solar panels can always operate at maximum efficiency on dust-free days.

Film is stored in a colder environment than other time-based media, and different types of film have different optimum storage temperatures. "Color film should be stored at the coldest possible temperature to reduce fading," 0-30 degrees Fahrenheit, while black and white film can be stored at a temperature of 25-50 degrees Fahrenheit. Magnetic videotape- Magnetic videotape was never meant to last, and often has a short life (often only a few decades) especially if exposed to warm or humid conditions. Videotapes, should be stored in upright, under cool, dry, dust-free conditions.

The United Kingdom, for example, has shipyards on many of its rivers. The site of a large shipyard will contain many specialised cranes, dry docks, slipways, dust-free warehouses, painting facilities and extremely large areas for fabrication of the ships. After a ship's useful life is over, it makes its final voyage to a shipbreaking yard, often on a beach in South Asia. Historically shipbreaking was carried on in drydock in developed countries, but high wages and environmental regulations have resulted in movement of the industry to developing regions.

Trujillo joined NASA in 2008, working at Goddard Space Flight Center on the Constellation program and the Jet Propulsion Laboratory on human and robotic space missions. She has served many roles, including Surface Sampling System Activity Lead and Dust Removal Tool Lead Systems Engineer. She was responsible for ensuring Curiosity's sampling fulfilled its science objectives dust-free whilst maintaining operational safety. The Dust Removal Tool took her six months to develop, and brushes the dust of the surface of Mars to allow scientists to investigate the surface below.

When removed from the allergens in the stable, the symptoms will usually subside, although they will recur if the horse is stabled again at a later date.Jackson CA, Berney C, Jefcoat AM, Robinson NE (2000), "Environment and prednisone interactions in the treatment of recurrent airway obstruction (heaves)", Equine Vet J. 32(5):432-8 If this is not practical, certain alterations to stable routine may be effective. The aim is to minimise dust and maximise air quality in the stable. This may be achieved by soaking hay or feeding a dust-free alternative (such as haylage).

Testing is often done in a clean-room or another dust-free environment, keeping the dust from settling on the surfaces between cleaning and assembly. Sometimes, the surfaces may be assembled by sliding them together, helping to scrape off any dust that might happen to land on the flat. The testing is usually done in a temperature-controlled environment to prevent any distortions in the glass, and needs to be performed on a very stable work-surface. After testing, the flats are usually cleaned again and stored in a protective case, and are often kept in a temperature-controlled environment until used again.

While working in the institute in collaboration with Leningrad’s researcher O.V. Mazurin, Yu. Belousov wrote the book The Annealing and Tempering of Glass, a popular and famous manual among engineers. This book, devoted to a new method of glass treatment, became a respected reference guide for specialists and researchers in other related industries. Based on this method, in 1988, Yu. Belousov, O.V. Mazurin and others developed USSR’s first technology of a glass dust-free method of sealing glass ampoules, which significantly decreased contamination in medicinal ampouled preparations. This invention was first introduced at one of the Soviet biopharmaceutical plants currently belonging to the Russian concern VEROPHARM.

A highly precise antenna mount is required to maintain the accuracy of the angle system. The FPS-16 antenna pedestal is a precision-machined item, engineered to close tolerances, assembled in dust-free, air-conditioned rooms to prevent warping during mechanical assembly. The pedestal is mounted on a reinforced concrete tower to provide mechanical rigidity. The electronic equipment is mounted in a two-story concrete building, which surrounds the tower to decrease tower warping due to solar radiation. The radar utilizes a parabolic antenna giving a beamwidth of 1.2 degrees at the half-power points. The range system uses 1.0, 0.5, or 0.25-microsecond wide pulses.

Trickle valves, also known as vacuum valves, are commonly used in industrial dust collection applications to maintain an airlock seal on a dust collector hopper while allowing bulk solid material to be automatically discharged. These valves are typically a less expensive alternative to more commonly used rotary airlocks. Unlike rotary airlock valves which are driven by either an electric motor or a gas or air-powered motor, trickle valves require no external power source and are therefore well-suited for use in mechanical trenchers, where a dust-free environment in the pinnacle truss and axle bore is required for smooth operation. Trickle values were originally developed for this purpose.

The Draco Dwarf contains primarily an old population of stars and insignificant amounts of interstellar matter (being basically dust free). From 75% to 90% of its stars formed more than ~10 Gyr ago followed by a low rate of formation with a small burst of star formation around 2-3 Gyr ago. It has a single Gaussian distribution with average metallicity of [Fe/H] = −1.74 dex with a standard deviation (sigma/σ) of 0.24 dex and a small tail of metal-rich stars. The central region of Draco Dwarf exhibits a concentration of more metal-rich stars there being more centrally concentrated red horizontal branch stars than blue horizontal branch stars.

Wednesday, 12 June 2019 Nearline tape and optical storage has the advantage of relatively longer lifespans compared to spinning hard drives, simply due to the storage media being idle and usually stored in protected dust-free enclosures when not in use. In a robotic tape loading system, the tape drive used for accessing data experiences the most wear and may need occasional replacement, but the tapes themselves can last for years to decades. If there are sealable access doors between the access mechanism and the media, it is possible for the idle media storage enclosure to survive fire, floods, lightning strikes, and other disasters.

The first step involves cleaning the playing surface of the records (unless they have been stored in archival, dust-free conditions since they were last cleaned). This can involve anything from turntable-based, vacuum equipped, professional cleaning machines that use proprietary chemical formulations and cost four figures, to improvised methods involving home-made equipment and/or cleaning solutions consisting of isopropyl alcohol, distilled water (unpurified tap water should not be used, as it will probably leave limescale deposits on the record surface) and a surfactant to aid drying. Isopropyl alcohol should only be used to clean vinyl records: it will cause permanent damage to shellac, master and one-time recordings (acetate, wax and lacquer).

There really is no need to add crockery to the bottom of the pot, but you may want to add a small square of wire mesh or other permiable fabric over hole in bottom of pot. Potting Epiphytic Orchids Epiphytes prefer conditions where roots can be exposed, therefore, tight pots and close-contact soil mixes do not work well and will induce rot. Mix 3 parts dust-free, medium-grade bark, 1 part coarse grit or perlite, 1 part charcoal, and 1 part peat moss together, OR use a commercial orchid mix. As with the terrestrial orchid, select a pot that will accommodate roots and about 2 years growth, but no more.

The resort's focus is on balneotherapy for circulatory, nervous, musculo-skeletal, gynaecological and skin diseases, but since the 1970s its repertoire has included "speleotherapy", in which the cool dust-free environment of local caves is said to benefit pulmonary diseases. Tskaltubo was especially popular in the Soviet era, attracting around 125,000 visitors a year. Bathhouse 9 features a frieze of Stalin, and visitors can see the private pool where he bathed on his visits. Currently the spa receives only some 700 visitors a year, and since 1993 many of the sanatorium complexes have been devoted to housing some 9000 refugees, primarily women and children, displaced from their homes by ethnic conflict in Abkhazia.

Mr and Mrs Barf always laugh at their surname because it sounds like "bath", and because they are the cleanest people around, having three baths a day and basing their married life on the phrase "Cleanliness is next to godliness", hoping that being clean and having a dust-free house will get them into Heaven. Meanwhile, their son, Bertie, is always filthy with food stuck to his clothes. The only time he cares about being clean is when he uses his toothbrush to clean the soles of his trainers. When his father asks him to bathe, Bertie refuses because it will drown the insects living in his hair, so his parents try to clean him as he sleeps, but they are caught by Bertie's homemade booby traps.

Therefore, to find planets in the Beta Pictoris system, astronomers look for the effects that the planet has on the circumstellar environment. ESO image of a planet near Beta Pictoris Multiple lines of evidence suggested the existence of a massive planet orbiting in the region around 10 AU from the star: the dust-free gap between the planetesimal belts at 6.4 AU and 16 AU suggest this region is being cleared out; a planet at this distance would explain the origin of the falling evaporating bodies, and the warps and inclined rings in the inner disk suggest a massive planet on an inclined orbit is disrupting the disk. elongations The observed planet by itself cannot explain the structure of the planetesimal belts at 30 AU and 52 AU from the star.

They also reported that, using the "beam of electrons that stream along the magnetic field", they were able to observe that "the reversals in the Sun's magnetic field are often associated with localized enhancements in the radial component of the plasma velocity (the velocity in the direction away from the Sun's centre)". The researchers found a "surprisingly large azimuthal component of the plasma velocity (the velocity perpendicular to the radial direction). This component results from the force with which the Sun's rotation slingshots plasma out of the corona when the plasma is released from the coronal magnetic field". Parker discovered evidence of a cosmic dust free zone of 3.5 million miles (5.6 million kilometres) radius from the Sun, due to vaporisation of cosmic dust particles by the Sun's radiation.

MAY, 1906 In May 1882, the government astronomer at Madras, Norman Robert Pogson, proposed the need for photography and spectrography of the sun and the stars using a twenty-inch telescope, which could be at a hill station in South India. On 20 July 1893 following a famine in Madras Presidency, which underscored the need for a study of the sun to better understand monsoon patterns, a meeting of the U.K. Secretary of State, Indian Observatories Committee, chaired by Lord Kelvin, decided to establish a solar physics observatory at Kodaikanal, based on its southern, dust free, high altitude location. Michie Smith was selected to be superintendent. Starting in 1895 there was a rapid transfer of work and equipment from the Madras Observatory to Kodaikanal and the observatory was founded on 1 April 1899.
