Unlike most of the early LAN systems, AppleTalk was not built using the archetypal Xerox XNS system.

Unlike most Common-law jurisdictions, the majority of civil law jurisdictions have specialized courts or sections to deal with administrative cases which, as a rule, will apply procedural rules specifically designed for such cases and different from that applied in private-law proceedings, such as contract or tort claims.

Unlike the NES or Sega Master System, there were few add-on peripherals for the 7800, though its backwards compatibility feature allowed it to be compatible with most Atari 2600 peripherals.

Unlike the communist parties in most other East European states, the BCP ( changing its name to Bulgarian Socialist Party ) retained majority power after the transition in Bulgaria by winning the first free national elections in June 1990.

Unlike most cranes, it has a relatively large head and a proportionately thin neck.

Unlike Zealous, these British ships suffered relatively severe damage in the engagement ; Goliath lost most of its rigging, suffered damage to all three masts and received over 60 casualties.

Unlike other C-suite positions, which tend to be defined according to commonly designated responsibilities across most companies, the COO job tends to be defined in relation to the specific CEO with whom he / she works, given the close working relationship of these two individuals.

Unlike in most other role-playing games, eventual triumph of the players is not assumed.

Unlike its predecessor games, CoC assumed that most investigators would not survive, alive or sane, and that the only safe way to deal with the vast majority of nasty things described in the rule books was to run away.

Unlike feces, urine doesn't attract disease-spreading flies ( such as house flies or blow flies ), and it doesn't contain the most hardy of pathogens, such as parasitic worm eggs.

Unlike Inter-city, it stops at most or all stations between cities.

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

Unlike other college football divisions and most other sports — collegiateor professional — the Football Bowl Subdivision, formerly known as Division I-A college football, does not employ a playoff system to determine a champion.

Unlike most ( private ) corporate bodies, creatures of statute cannot expand their business interests into other diverse areas.

Unlike the modern historian, most chroniclers tended to take their information as they found it, and made little attempt to separate fact from legend.

Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place.

Unlike most amnesiacs, Leonard retains his identity and the memories of events that occurred before the injury, but loses all ability to form new memories.

Unlike most other DOS systems, it was integrated into the disk drives, not loaded into the computer's own memory.

Unlike most social canids ( but similar to African wild dogs ), dholes let their pups eat first at a kill.

Unlike the violone, however, the fingerboard of the double bass is unfretted, and the double bass has fewer strings ( the violone, like most viols, generally had six strings, although some specimens had five or four ).

Unlike most other external DOS commands, it has not been transformed into a native Win32 program.

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 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 gas stoves that are powered by gas, it is powered by electricity.

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.
