Water Restrictions
An outdoor water-use restriction is a ban or other lesser restrictions put into effect that restricts the outdoor use of water supplies. Often called a watering ban or hosepipe ban, it can affect: *irrigation of lawns * car washing *recreational uses such as filling swimming pools and using water slides *planting of grass or control of the types of grass planted * hosing down pavement areas Such bans may be put in place by local governments, a state government or water supplier. In the latter case, local authorities often still can enact more restrictive measures. Such a ban is usually enacted during droughts, to preserve water for essential uses such as drinking and flushing toilets, as well as for firefighting. If there is a water main break, or a problem with a water tower or other reservoir, a ban may be enacted on a very local and temporary basis. Bans that control water and plant uses can be permanent.

Ban (law)
A ban is a formal or informal prohibition of something. Bans are formed for the prohibition of activities within a certain political territory. Some bans in commerce are referred to as embargoes. ''Ban'' is also used as a verb similar in meaning to "to prohibit". Etymology In current English usage, ''ban'' is mostly synonymous with ''prohibition''. Historically, Old English ''(ge)bann'' is a derivation from the verb ''bannan'' "to summon, command, proclaim" from an earlier Common Germanic ''*bannan'' "to command, forbid, banish, curse". The modern sense "to prohibit" is influenced by the cognate Old Norse ''banna'' "to curse, to prohibit" and also from Old French ''ban'', ultimately a loan from Old Frankish">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... ''ban'', ultimately a loan from Old Frankish, meaning "outlawry, banishment". The Indo-European etymology of the Germanic term is from a root ...

Firefighting
Firefighting is a profession aimed at controlling and extinguishing fire. A person who engages in firefighting is known as a firefighter or fireman. Firefighters typically undergo a high degree of technical training. This involves structural firefighting and wildland firefighting. Specialized training includes aircraft firefighting, shipboard firefighting, aerial firefighting, maritime firefighting, and proximity firefighting. Firefighting is a dangerous profession due to the toxic environment created by combustible materials, with major risks being smoke, oxygen deficiency, elevated temperatures, poisonous atmospheres, and violent air flows. To combat some of these risks, firefighters carry self-contained breathing apparatus. Additional hazards include falling (accident), falls – a constant peril while navigating unfamiliar layouts or confined spaces amid shifting debris under limited visibility – and structural collapse that can exacerbate the problems encountered in a toxi ...

Recycle
ReCycle is a music loop editor designed and developed by Sweden, Swedish software developers Propellerhead Software. It runs on Microsoft Windows and Apple Macintosh based Personal Computer, PCs. The software debuted in 1994. The principal idea of ReCycle is to alter the tempo of a music loop without changing its Pitch (music), pitch or otherwise altering its sound. ReCycle does this by "slicing" loops into a series of separate "beats" or "hits" and altering their timing (or even quantizing them) without altering the length of the individual slices, thus allowing the loop to play at a different speed whilst using the unmodified sounds for each individual slice/drum hit, a process which fully preserves the original pitch of the loop while allowing a great variety of speed/timing tweaks. ReCycle can also assign each successive slice to a respective MIDI note on a scale. ReCycle was the first program to popularize the idea of loop slicing. Propellerhead developed their own file for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landscaping
Landscaping refers to any activity that modifies the visible features of an area of land, including the following: # Living elements, such as flora or fauna; or what is commonly called gardening, the art and craft of growing plants with a goal of creating a beauty within the landscape. # Natural abiotic elements, such as landforms, terrain shape and elevation, or bodies of water. # Abstract elements, such as the weather and lighting conditions. Landscaping requires a certain understanding of horticulture and artistic design, but is not limited to plants and horticulture. Sculpting land to enhance usability (patio, walkways, ponds, water features) are also examples of landscaping being used. When intended as purely an aesthetic change, the term Ornamental Landscaping is used. Often, designers refer to landscaping as an extension of rooms in your house (each one has a function). Outdoor spaces have a vast amount of flexibility as far as materials and function. It is often said th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Nurseries
A nursery is a place where plants are propagated and grown to a desired size. Mostly the plants concerned are for gardening, forestry, or conservation biology, rather than agriculture. They include retail nurseries, which sell to the general public; wholesale nurseries, which sell only to businesses such as other nurseries and commercial gardeners; and private nurseries, which supply the needs of institutions or private estates. Some will also work in plant breeding. A "nurseryman" is a person who owns or works in a nursery. Some nurseries specialize in certain areas, which may include: propagation and the selling of small or bare root plants to other nurseries; growing out plant materials to a saleable size, or retail sales. Nurseries may also specialize in one type of plant, e.g., groundcovers, shade plants, or rock garden plants. Some produce bulk stock, whether seedlings or grafted trees, of particular varieties for purposes such as fruit trees for orchards or timber t ...

Carwash
A car wash, or auto wash, is a facility used to clean the exterior, and in some cases the interior, of cars. Car washes can be self-service, full-service (with attendants who wash the vehicle), or fully automated (possibly connected to a filling station). Car washes may also be events where people pay to have their cars washed by volunteers, often using less specialized equipment, as a fundraiser. History The first U.S. patent for a mechanized car wash was filed in 1900 and soon followed by "auto laundries". The Automobile Laundry in Detroit, Michigan, opened in 1914 by Frank McCormick and J.W. Hinkle, is considered the first business in the U.S. to adopt the name "car wash" for their services. Manual car wash operations, which used manpower to push or move the cars through stages, peaked at 32 drive-through facilities in the United States. The first semi-automatic car wash in the United States debuted in 1946 at a facility in Detroit, which used automatic pulley systems ...

Irrigation Sprinkler
An irrigation sprinkler (also known as a water sprinkler or simply a sprinkler) is a device used to irrigate (water) agricultural crops, lawns, landscapes, golf courses, and other areas. They are also used for cooling and for the control of airborne dust. Sprinkler irrigation is the method of applying water in a controlled manner in way similar to rainfall. The water is distributed through a network that may consist of pumps, valves, pipes, and sprinklers. Irrigation sprinklers can be used for residential, industrial, and agricultural usage. It is useful on uneven land where sufficient water is not available as well as on sandy soil. The perpendicular pipes, having rotating nozzles on top, are joined to the main pipeline at regular intervals. When water is pressurized through the main pipe it escapes from the rotating nozzles. It gets sprinkled on the crop. In sprinkler or overhead irrigation, water is piped to one more central locations within the field and distributed by overh ...

Drip Irrigation
Drip irrigation or trickle irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the rhizosphere, root zone and minimize evaporation. Drip irrigation systems distribute water through a network of valves, pipes, tubing, and emitters. Depending on how well designed, installed, maintained, and operated it is, a drip irrigation system can be more efficient than other types of irrigation systems, such as surface irrigation or sprinkler irrigation. As of 2023, 3% of the world's farmers use drip irrigation. History Ancient China Primitive drip irrigation has been used since ancient times. ''Fan Shengzhi shu'', written in China during the first century BCE, describes the use of buried, unglazed clay pots filled with water, sometimes referred to as Olla#Use in irrigation, Ollas, as ...

Evaporation
Evaporation is a type of vaporization that occurs on the Interface (chemistry), surface of a liquid as it changes into the gas phase. A high concentration of the evaporating substance in the surrounding gas significantly slows down evaporation, such as when humidity affects rate of evaporation of water. When the molecules of the liquid collide, they transfer energy to each other based on how they collide. When a molecule near the surface absorbs enough energy to overcome the vapor pressure, it will escape and enter the surrounding air as a gas. When evaporation occurs, the energy removed from the vaporized liquid will reduce the temperature of the liquid, resulting in evaporative cooling. On average, only a fraction of the molecules in a liquid have enough heat energy to escape from the liquid. The evaporation will continue until an equilibrium is reached when the evaporation of the liquid is equal to its condensation. In an enclosed environment, a liquid will evaporate unt ...

Spray (liquid Drop)
A spray is a dynamic collection of drops dispersed in a gas. The process of forming a spray is known as atomization. A spray nozzle is the device used to generate a spray. The two main uses of sprays are to distribute material over a cross-section and to generate liquid surface area. There are thousands of applications in which sprays allow material to be used most efficiently. The spray characteristics required must be understood in order to select the most appropriate technology, optimal device and size. Formation Spray atomization can be formed by several methods. The most common method is through a spray nozzle which typically has a fluid passage that is acted upon by different mechanical forces that atomize the liquid. The first atomization nozzle was invented by Thomas A. DeVilbiss of Toledo, Ohio in the late 1800s. His invention was a bulb atomizer that used pressure to impinge upon a liquid, breaking the liquid into a fine mist. Spray formation has taken on several forms, ...

Greywater
Greywater (or grey water, sullage, also spelled gray water in the United States) refers to domestic wastewater generated in households or office buildings from streams without fecal contamination, i.e., all streams except for the wastewater from toilets. Sources of greywater include sinks, showers, baths, washing machines or dishwashers. As greywater contains fewer pathogens than blackwater, it is generally safer to handle and easier to treat and reuse onsite for toilet flushing, landscape or crop irrigation, and other non- potable uses. Greywater may still have some pathogen content from laundering soiled clothing or cleaning the anal area in the shower or bath. The application of greywater reuse in urban water systems provides substantial benefits for both the water supply subsystem, by reducing the demand for fresh clean water, and the wastewater subsystems by reducing the amount of conveyed and treated wastewater. Treated greywater has many uses, such as toilet fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
