Unlike the other gas giants, Uranus has an extreme tilt that causes its seasons to be severely pronounced.

Unlike gas balloons, the envelope does not have to be sealed at the bottom since the air near the bottom of the envelope is at the same pressure as the surrounding air.

Unlike the Schrödinger's cat thought experiment which used poison gas and a radioactive decay trigger, this version involves a life-terminating device and a device that measures the spin value of protons.

Unlike aerodynamic aircraft such as fixed-wing aircraft and helicopters, which produce lift by moving a wing through the air, aerostatic aircraft stay aloft by having a large " envelope " filled with a gas which is less dense than the surrounding atmosphere.

Unlike most gas turbines, an emergency power unit has no gas compressor or ignitors, and uses a combination of hydrazine and water, rather than jet fuel.

Unlike a classical ideal gas, whose pressure is proportional to its temperature ( P = nkT / V, where P is pressure, V is the volume, n is the number of particles — typically atoms or molecules — k is Boltzmann's constant, and T is temperature ), the pressure exerted by degenerate matter depends only weakly on its temperature.

Unlike many other arachnids, ricinuleids have no book lungs, and gas exchange takes place through trachea.

Unlike noble gases, an inert gas is not necessarily elemental and is often a compound gas.

Unlike other shunt protector devices, a GDT once triggered will continue to conduct at a voltage less than the high voltage that initially ionized the gas ; this behavior is called negative resistance.

Unlike an ideal gas, though, in which tiny particles move constantly, stopping the shaking would simply cause the beads to drop.

Unlike isolated systems, like atoms or molecules in gas phase, the density distributions are not discrete like a spectral density but continuous.

Unlike conventional gas-operated firearms, direct impingement does away with a separate gas cylinder, piston, and operating rod assembly.

Unlike much natural gas from conventional reservoirs, coalbed methane contains very little heavier hydrocarbons such as propane or butane, and no natural gas condensate.

Unlike gas, liquid, or solid-state lasers such as diode lasers, in which electrons are excited in bound atomic or molecular states, FELs use a relativistic electron beam as the lasing medium which moves freely through a magnetic structure, hence the term free electron.

Unlike most other gas switch tubes, the krytron uses arc discharge to handle very high voltages and currents ( several kV and several kA peak ), rather than the usual low-current glow discharge.

Unlike most centrifuges which rely on batch processing, the gas centrifuge utilizes continuous processing, allowing cascading, in which multiple identical processes occur in succession.

Unlike the M16 where the gas is directed into a cavity around the bolt, the MAS system vents the gas to the air after expanding in a hollow on the bolt carrier.

Unlike the DEFA cannon, the revolver chamber is electrically operated, rather than gas operated, improving both reliability and rate of fire.

Unlike ionizers, ozone generators are designed to produce significant amounts of ozone, a strong oxidant gas which can oxidize many other chemicals.

Unlike many decorative patterns that present a static flat convention, this artist's pictures are full of atmosphere and climate.

Unlike conventional auctions, bids are non-refundable ; if one player bids 65 for psyche and another wins with a bid of 66, then the character with 66 is " superior " to the character with 65 even though there is only one bid difference.

Unlike the Oriental Natural, the Akoya pearl, and the South Sea and Tahitian cultured pearls, abalone pearls are not primarily judged by their roundness.

Unlike gingerbread (), which is sweetened with honey, Printen are sweetened with sugar.

Unlike his translation of the Pastoral Care, Alfred here deals very freely with his original and though the late Dr. G. Schepss showed that many of the additions to the text are to be traced not to Alfred himself, but to the glosses and commentaries which he used, still there is much in the work which is solely Alfred's and highly characteristic of his style.

Unlike McCaffrey's black crystal transceivers, Le Guin's ansibles are not mated pairs: it is possible for an ansible's coordinates to be set to any known location of a receiving ansible.

Unlike the typical idea of an arcology-clean, healthy, and safe for the environment, " hives " are portrayed as dirty, diseased, overcrowded and the area around them as highly polluted.

Unlike the Israelite worship assembly, which was only able to look on during Temple worship as the Levitical Priest sang, played, and offered animal sacrifices, in the New Testament, all Christians are commanded to sing praises to God.

Unlike France or Germany, there are no special administrative courts of first instance in the Netherlands, but regular courts have an administrative " chamber " which specializes in administrative appeals.

Unlike modern websites and online services that are typically hosted by third-party companies in commercial data centers, BBS computers ( especially for smaller boards ) were typically operated from the SysOp's home.

Unlike many former Soviet bloc militaries, discipline and morale problems are not common.

Unlike their counterparts in the United Methodist Church, ELCA and ELCIC synod bishops do not appoint pastors to local congregations ( pastors, like their counterparts in the Episcopal Church, are called by local congregations ).

Unlike lawn bowls, bocce balls are spherical and have no inbuilt bias.

Unlike bioweapons, these midspectrum agents do not reproduce in their host and are typically characterized by shorter incubation periods.

Unlike the closely related pea, beans are a summer crop that needs warm temperatures to grow.

Unlike ecozones, biomes are not defined by genetic, taxonomic, or historical similarities.

Unlike traditional HTML with its large range of character entity references, in XML there are only five predefined character entity references.

Unlike with geographical maps, where many famous projections are known ( such as the Mercator projection ), the calendar projection is a matter of such triviality that no names for these exist in common circulation.

Unlike cosmogenic isotopes that are produced in the atmosphere, < sup > 41 </ sup > Ca is produced by neutron activation of < sup > 40 </ sup > Ca.

" Unlike utilitarianism, which views pleasure as a moral good, " the basic goods in Mohist consequentialist thinking are ... order, material wealth, and increase in population ".

Unlike structs, arrays are not first-class objects ; they cannot be assigned or compared using single built-in operators.

Unlike the other proposition bets which are handled by the dealers or stickman, the field bet is placed directly by the player.

Unlike the gradient and divergence, curl does not generalize as simply to other dimensions ; some generalizations are possible, but only in three dimensions is the geometrically defined curl of a vector field again a vector field.

Unlike the primary wall, the microfibrils are aligned mostly in the same direction, and with each additional layer the orientation changes slightly.

Unlike most sports, men and women compete and are ranked together.
