Because higher-density parts have little exposed oxide between the layers of interconnects and gate, ultraviolet erasing becomes less practical for very large memories.

Several attempts have been made by commercial developers to buy up Pimmit properties and convert them to higher-density housing such as condominiums or town houses, but so far these have been resisted by homeowners.

A recent surge of higher-density real estate development, centred in the Old City / Downtown area, as well as construction of a city-funded waterfront conference centre, have proven controversial.

Typically " field-bales ", bales created on farms with baling machines have been used, but recently higher-density " precompressed " bales ( or " straw-blocks ") are increasing the loads that may be supported.

Typically, bales created on farms with mobile machinery have been used (" field-bales "), but recently higher-density " recompressed " bales ( or " straw-blocks ") are increasing the loads that may be supported ; where field bales might support around 600 pounds per linear foot of wall, the high density bales bear up to 4, 000 lb ./ lin. ft.

Rises in land values due to gentrification, have resulted in many of the industrial uses vacating their buildings, which have become attractive to developers of medium and higher-density residential projects, often with a small commercial or retail component.

In more recent years there has been considerable " infill " as many of the larger lots and other remaining open spaces have been redivided to become the sites of higher-density developments.

The combination of private retention of publicly created increases in land value and land-use zoning laws creates an even stronger economic pressure to hold valuable land out of use or in an inferior use: rezoning a land parcel to allow more intensive, higher-density use often results in a very large increase in the land's value.

) AST's original business was the manufacture and marketing of a broad range of microcomputer expansion cards, later focusing on higher-density replacements for the standard I / O cards in the IBM PC.

Over its lifespan, the processor's technology has been redesigned to integrate all the circuitry into a single chip and to refresh the manufacturing process ( as the foundry could no longer manufacture the necessary chips, having moved on to making higher-density chips ).

Compared to 110 and higher-density wire terminating blocks, 66 blocks are physically large ; and because of their maximum 16 MHz Category 3 signaling compatibility, they are ill-suited for high speed ( faster than 10BASE-T ) data circuits.

Many crystalline minerals can be transformed into higher-density phases by shock waves ; for example, the common mineral quartz can be transformed into the higher-pressure forms coesite and stishovite.

Gallium shares the higher-density liquid state with only a few materials like silicon, germanium, bismuth and water.

In Australia, the terms inner suburb and outer suburb are used to differentiate between the higher-density suburbs in proximity to the city center, and the lower-density suburbs on the outskirts of the urban area.

1GB on a new, higher-density Hi-MD.

If we attempt to move to a point that is more probable than the existing point ( i. e. a point in a higher-density region of ), we will always accept the move.

In late 2005, city government began holding public meetings to discuss whether and how to improve this small area in order to develop a higher-density pedestrian-friendly shopping and residential hub.

In the early 1980s, however, bubble memory became a dead end with the introduction of higher-density, faster, and cheaper hard disk systems.

RAM could be maxed out to 128 MB, however, if the ROMs were upgraded to those used in the IIx ( or if MODE32 was used ), as the Mac II's memory controller supported higher-density memory modules than did the stock ROM.

Airy isostasy, in which a constant-density crust floats on a higher-density mantle, and topography is determined by the thickness of the crust.

The Auckland Regional Council accepted that while it was encouraging intensified growth ( such as higher-density housing ) around transport nodes such as Devonport, the character and historical nature of the Devonport Wharf area would make such a designation inappropriate in this case.

As the city's suburbs continued to sprawl outwards, the Bracks government sought to restrict new suburban growth to designated growth corridors and encourage higher-density apartment living in the city's main transport hubs.

Thin metal pins, especially in higher-density connectors, are easily bent or broken, particularly if frequently plugged in by touch behind equipment.

With newer, higher-density and smaller scale modules, 768 MB was easily within heat output specifications.

The historic core was repurposed as a new town center with retail, entertainment attractions, and additional, higher-density housing.

However, the character of the suburb is changing rapidly, with increased road traffic and higher-density housing becoming more common.

As part of the Melbourne 2030 planning policy, Ringwood became a designated ' Transit City ', as a push to locate higher-density development near public transport facilities.

Transit-oriented development, in which higher-density mixed-use areas are permitted or encouraged near transit stops is encouraging more compact development in certain areas-particularly those with light and heavy rail transit systems.

In urethane foams, for example, there has been a definite trend toward the polyether-type materials ( which are now available in two-component rigid foam systems ) and the emphasis is definitely on one-shot molding.

Much interest has also been expressed in new techniques for processing the urethane foams, including spraying, frothing, and molding ( see article, p. 391 for details ).

Most commercial uses of urethane foams require densities between 2 and 30 lb. / cu. ft. for rigid foams, between 1 and 3 lb. / cu. ft. for flexible foams.

In flexible urethane foams, we are referring to the range between the highest and lowest temperatures under which the materials' primary performance remains functionally useful.

The K factor, a term used to denote the rate of heat transmission through a material ( B.t.u./sq. ft. of material/hr./*0F./in. of thickness ) ranges from 0.24 to 0.28 for flexible urethane foams and from 0.12 to 0.16 for rigid urethane foams, depending upon the formulation, density, cell size, and nature of blowing agents used.

( like compression strength of urethane foams, it has a direct relationship to formulation.

Figure 2, above, shows the aging properties of urethane foams as determined by the percent of change in tensile strength during exposure to ultra-violet light.

The closed molding of flexible urethane foams has been a problem ever since the introduction of the material ( molding in open molds was more feasible ).

In 1967, urethane modified polyisocyanurate rigid foams were introduced, offering even better thermal stability and flammability resistance compared to low-density insulation products.

Like other tertiary amines, it catalyzes the formation of urethane foams and epoxy resins.

These are usually latex, polyester, urethane or epoxy compounds which are applied in liquid form to provide a completely seamless floor covering.

Anti-rockers are usually made of Nylon, or a substantially harder urethane than normal wheels, which means if a skater were to catch either of their center wheels on the grinding surface, they are less likely to be slowed or halted by friction between the wheel and rail or ledge.

An air mattress, also known as an airbed is an inflatable mattress, the wide majority of which are usually made of PVC vinyl plastic although recently developed textile-reinforced urethane plastic or rubber versions exist.

The Fiber drums referred to above will easily hold, and are usually coated internally with a urethane or plastic protective coating.

Modern balls usually consist of several layers of various synthetic materials like surlyn or urethane blends.
