Although aluminium has a low gastrointestinal absorption, accumulation may occur mainly in the presence of renal insufficiency.

Double salts are often less soluble, and the low solubility of caesium aluminium sulfate is exploited in the purification of Cs from its ores.

A low aluminium glass mirror is manufactured by coating silver and two layers of protective paint on the back surface of glass.

Many commercial sextants use low expansion brass or aluminium.

* Further, the low density of the aluminium oxide formed as a result of the reaction tends to cause it to float on the resultant pure metal.

The biggest disadvantage is that it can only be used with low melting point non-ferrous materials, such as aluminium, copper, magnesium, and zinc.

The body, which exploits large aluminium extrusion technology, has substantial modularity and allows for extremely low axle weight, whilst fully respecting the highest safety standards, and allows the best exploitation of the space with different loading gauges.

Magnetite concentrate grades are generally in excess of 63 % iron by weight and usually are low phosphorus, low aluminium, low titanium and low silica and demand a premium price.

Some conditions that inhibit passivation include high pH for aluminium and zinc, low pH or the presence of chloride ions for stainless steel, high temperature for titanium ( in which case the oxide dissolves into the metal, rather than the electrolyte ) and fluoride ions for silicon.

The very high electric current is supplied to the cells through heavy, low electrical resistance metal busbars made of pure aluminium or copper.

Olympia & York wanted to clad One Canada Square in stone, just like the World Financial Center buildings, but the architects first wanted to use aluminium for its low density, before insisting on steel to reflect Britain's heritage as

Its extruded aluminium space frame and lightweight composite body shell are factors in its low curb weight of.

Nowadays other metals such as aluminium, titanium, magnesium, and beryllium, as well as various alloys thereof, are used, being both light and stiff but having low damping ; their resonant modes occur above 20 kHz.

Their low volatility and water clean up makes them useful for factory cast iron, cast steel, cast aluminium applications and reduces exposure and flammability issues associated with solvent-borne coatings.

Aluminium, while requiring a thin barrier metal to promote low ohmic resistance when making a contact directly to silicon or aluminium layers, did not require barrier metals on the sides of the metal lines to isolate aluminium from the surrounding silicon oxide insulators.

The body, which exploits large aluminium extrusion technology, has substantial modularity and allows for extremely low axle weight, whilst fully respecting the highest safety standards, and allows the best exploitation of the space with different loading gauges.

Melting of such rocks to a very low degree promotes the liberation of aluminium, potassium, sodium and calcium via melting of feldspar, with some involvement of mafic minerals.

Furthermore, at high aluminium concentrations, an oxide can be formed from AlGaAs, and this oxide can be used to restrict the current in a VCSEL, enabling very low threshold currents.

Permanent cropping of oxisols in low-income areas is very difficult because of low cation exchange capacities and high phosphorus fixation on iron and aluminium oxides ( ligand exchange mechanism ; inner sphere complex with phosphate ).

Electromigration can be a cause of degradation in some power semiconductor devices such as low voltage power MOSFETs, in which the lateral current through the source contact metallisation ( often aluminium ) can reach the critical current densities during overload conditions.

Looking around slowly, he saw a marble fireplace, a desk, a low bookcase of mahogany with criss-crossed brass wire instead of glass panes in the doors.

It squatted low and square upon the sidewalk with a heavy iron grating supporting a glass facade.

It was only in the 1990s that the price for Chinese-derived erbium oxide became low enough for erbium to be considered for use as a colorant in art glass.

Thorium oxide gives glass a high refractive index and low dispersion and was formerly used in producing high-quality lenses, but due to its radioactivity has been replaced by lanthanum oxide in modern eye glasses.

They have fairly low coefficients of thermal expansion ( 7740 Pyrex CTE is 3. 25 /° C as compared to about 9 /° C for a typical soda-lime glass ), making them more dimensionally stable.

The raw materials for laboratory-scale glass melts are often different from those used in mass production because the cost factor has a low priority.

* Lanthanum ( III ) oxide ( La < sub > 2 </ sub > O < sub > 3 </ sub >) improves the alkali resistance of glass, and is used in making special optical glasses, such as infrared-absorbing glass, as well as camera and telescope lenses, because of the high refractive index and low dispersion of rare-earth glasses.

To this end the glass is of a special low iron type that allows 90 % of the ultraviolet light in sunlight to pass.

Using a process called sputtering, silver along with other optically transparent layers are applied to glass creating low emissivity coatings used in high performance insulated glazing or IGU.

The insulating material was traditionally a form of SiO < sub > 2 </ sub > or a silicate glass, but recently new low dielectric constant materials are being used.

* SLD glass, a type of glass with low dispersion

With a trackball, the operator just continues rolling ( however, it could be argued that a mouse user could simply increase sensitivity and / or increase mousepad size to avoid this problem ) Some trackballs, such as Logitech's optical-pickoff types, have notably low friction, as well as being dense ( glass ), so they can be spun to make them coast.

Toughened glass is a common option as it is feasible however there is also low iron glass better known as opti-white glass which increases light and solar heat transmission.

Note that " achromat " and " apochromat " refer to the type of correction ( 2 or 3 wavelengths correctly focused ), not the degree ( how defocused the other wavelengths are ), and an achromat made with sufficiently low dispersion glass can yield significantly better correction than an achromat made with more conventional glass.

These are low dispersion glass, most notably, glasses containing fluorite.

* 1924 – Pyrex invented by scientists at Corning Incorporated, a glass with a very low coefficient of thermal expansion

* borosilicate Borosilicate glass, also known as pyrex, is useful because it has a very low coefficient of thermal expansion and is resistant to cracking when heated, unlike soda glass.

Photomultiplier cosmic-ray observatories often make use of these mirrors for inexpensive large ( 1. 0 m and above ), lightweight mirror surfaces for sky-sector low and medium energy cosmic ray research.

Rear-view mirror impact is a significant occurrence in a frontal collision ; how should a mirror be built so that it is both rigid enough to perform its task and yet of low injury risk if struck.

X-ray photons would be absorbed by normal mirror surfaces, so mirrors with a low grazing angle are necessary to reflect them.

The mirror finish of a chrome finish reduces heat transmission to the environment due to the low surface emissivity, a characteristic common to most highly polished surfaces.

When the mirror above the lens is moved too high or too low, it moves out of the best focal distance for an evenly white image, resulting in a projected image with either blue or brown color fringing around the outside edge of the screen.

Cutting horses are excellent examples, as they crouch low and back on their hindquarters so they may quickly move side to side to mirror the movements of the calf.

The California Institute of Technology's telescope mirror at Palomar Observatory was cast by Corning during 1934 – 1936 out of low expansion borosilicate glass.

Corning Incorporated also manufactures a high-purity fused silica employed in microlithography systems, a low expansion glass utilized in the construction of reflective mirror blanks, windows for U. S. space shuttles, and Steuben art glass.

Immediately before the chrome copy tape came into contact with the mirror mother master, a focused laser beam heated it to its Curie point at which its value of coercivity dropped to very low values so that it picked up a near perfect copy of the master as it cooled.

Its low coefficient of thermal expansion also makes it a useful material for precision mirror substrates.

The surface also tarnished rapidly ; the consequent low reflectivity of the mirror and also its small size meant that the view through the telescope was very dim compared to contemporary refractors.

Bright is elated, but he is also frustrated at Hannah's low self-esteem and forces her to see that she is beautiful by locking her in the bathroom and refusing to let her out until she looks at herself in the mirror.

Like magnetic monopoles, mirror matter could have been diluted to unobservably low densities during the inflation epoch.

A low value for R < sub > E </ sub > means V < sub > 2 </ sub > also is small, allowing a low compliance voltage for this mirror, only a voltage V < sub > 2 </ sub > larger than the compliance voltage of the simple bipolar mirror.

For this reason this type of mirror also is called a wide-swing current mirror, because it allows the output voltage to swing low compared to other types of mirror that achieve a large R < sub > out </ sub > only at the expense of large compliance voltages.
