Drip-irrigation systems employ small gaps at standard distances in a hose, leading to the slow trickle of water droplets which percolate the soil over a protracted period.

Toner particles are designed to have electrostatic properties and can develop static-electric charges when they rub against other particles, objects, or the interiors of transport systems and vacuum hoses.

In the mid-20th century, with the integration of fire-control systems into major cities, police found that high-pressure fire hoses could be effective in dispersing a crowd ( the use of water cannons and fire trucks has remained an effective nonlethal tactic to disperse riots ).

Most bicycle brake systems consist of three main components: a mechanism for the rider to apply the brakes, such as brake levers or pedals ; a mechanism for transmitting that signal, such as Bowden cables, hydraulic hoses, rods, or the bicycle chain ; and the brake mechanism itself, a calliper or drum, to press two or more surfaces together in order to convert, via friction, kinetic energy of the bike and rider into thermal energy to be dissipated.

Similar braiding is used on pressurized rubber hoses, such as in plumbing and hydraulic brake systems in automobiles.

Toner particles have electrostatic properties by design and can develop static-electric charges when they rub against other particles, objects, or the interiors of transport systems and vacuum cleaner hoses.

Detail parts of other materials are sometimes included in kits or sold separately, such as metal tubing to simulate exhaust systems, or vinyl tubing to simulate hoses or wiring.

Furthermore, being the first production Honda motorcycle with fuel-injection, the engine control system is complex and, by current standards, quite bulky, requiring two separate enclosures as well as a number of pressure-carrying hoses, mostly due to the ignition and injection systems being separate from each other.

Examples of less frequent home maintenance that should be regularly forecast and budgeted include repainting or staining outdoor wood or metal, repainting masonry, waterproofing masonry, cleaning out septic systems, replacing sacrificial electrodes in water heaters, replacing old washing machine hoses ( preferably with stainless steel hoses less likely to burst and cause a flood ), and other home improvements such as replacement of obsolete or aging systems with limited useful lifetimes ( water heaters, wood stoves, pumps, and asphaltic or wooden roof shingles and siding.

To avoid this problem, on many systems with a balloon loop the couplings and brake hoses are made reversible.

The core activity is hoses and fluid handling systems for industrial and automotive applications concentrating on air conditioning and breathing air.

Brake bleeding is the procedure performed on hydraulic brake systems whereby the brake lines ( the pipes and hoses containing the brake fluid ) are purged of any air bubbles.

Using launch systems presently available, we are developing satellites to scout the world's weather ; ;

Both of these systems are essential for the production, development, and use of the National Forests.

A substantial increase is estimated in the cost of operating additional communications systems in the air defense program, as well as in all programs where speed and security of communications are essential.

This aircraft, which was planned for initial operational use about 1965, would be complementary to but likewise competitive with the four strategic ballistic missile systems, all of which are scheduled to become available earlier.

Among the items scheduled for acceleration in the near future are the Polaris and B70 programs, strengthening of the airborne alert system of the Strategic Air Command, and improved battlefield surveillance systems.

Research and development expenditures connected with the reconnaissance satellite SAMOS and the future development of ballistic missile defense systems such as Nike-Zeus are expected to increase substantially.

These systems are more expensive than year-'round forced air systems.

Commonly used electronic devices which are found in practically every hospital are closed-circuit TV and audio systems for internal paging and instruction, along with radiation counters, timers, and similar devices.

Outputs of the two systems are measured by a pulse-timing circuit and a resistance bridge, followed by a simple analogue computer which feeds a multichannel recorder.

The air conditioning and ventilating systems of large buildings are subject to attack.

Even beginning students in linguistics are made familiar with an appreciable variety of consonant systems, both in their general outlines and in many specific details.

Tone systems are certainly more complex than the number of units would suggest, and often analytically more difficult than much larger consonantal systems.

Some phonetic features, for example glottal catch or murmur, are sometimes to be assigned to segmental phonemics and sometimes to accentual systems.

But no other two phonologic systems are as difficult to disentangle as are tone and intonation in some languages.

The phonemic systems which must support these morphophonemic systems, however, are very different.

Consonantal systems are not merely larger, they are multidimensional.

The difficulty of analysis of any subsystem in the phonology is an inverse function of the size -- smaller systems are more troublesome -- for any given degree of morphophonemic complexity.

This hypothesis will account for a large part of the difficulties of tonal analysis, as well as the fact that vowel systems are often more puzzling than consonantal systems.

what is new and compelling is that the West is now but one of several powerful civilizations, or `` systems '', and that one or more of the others may pose a mortal danger to the West.

This has necessitated a continuous review and reevaluation of the defense program in order to redirect resources to the newer and more important weapons systems and to eliminate or reduce effort on weapons systems which have been overtaken by events.

One of the more remarkable of the new cooling systems is one that can be switched to heating.

Many companies have systems, particularly in R & D, which work more or less well, depending upon size and actual belief in the policy on the part of administration, as will be abundantly apparent in subsequent quotations.

Where boundary maintenance describes the boundaries or limits of the group, systemic linkage is defined `` as the process whereby one or more of the elements of at least two social systems is articulated in such a manner that the two systems in some ways and on some occasions may be viewed as a single unit.

Observers, in the two school systems studied here, judged the teachers in the structured schools to be more impersonal and demanding, while the atmosphere in the unstructured schools was judged to be more supporting and accepting.

An advanced student has read a considerable number of descriptions of consonantal systems, including some of the more unusual types.

By contrast, even experienced linguists commonly know no more of the range of possibilities in tone systems than the over-simple distinction between register and contour languages.

Tone analysis will continue to be difficult and unsatisfactory until a more representative selection of systems is familar to every practicing field linguist.

Smaller systems can of course be stated much more succinctly.

In municipal systems we tend to view what is called positivism as fundamentally a movement to democratize policy by increasing the power of parliament -- the elected representatives -- at the expense of the more conservative judiciary.

As already noted in an earlier paragraph, the more familiar cost analyses of utility enterprises or utility systems divide the total costs among a number of major classes of service, such as residential, commercial, industrial power, street lighting, etc..

At one extreme are the systems of upper New York State, where libraries in two or more counties combine to serve a large, sparsely populated area.
