Noise (environmental) - Noise (environmental) Noise is unwanted sound. This is however subjective: some sounds are considered noise by some but not by others, e.g. certain music, church bells, calls to prayers from a minaret, sounds of playing children, birds, wind, sea, etc. It is one of the most underestimated causes of health damage. There are several kinds of noise by source, including aviation noise, car noise, train noise and industrial noise. See also: Antinoise.
Aviation noise - Aviation noise Aviation noise is one of the most well-publicised forms of environmental noise. Starts, approach and landing of aircraft cause very serious dangers for health. A starting aircraft may lead to a noise of more than 100 dB(A) at the ground. Modern aircraft are less noisy during start. Even more problematic is the landing approach. Since aircraft landing in inner-city airports are often lower than 200 ft (60 m) above the roof level, they cause a noise of more than 95 dB(A). Aviation noise is a serious health problem. It causes heart diseases, immune deficiencies, neurodermitis, asthma and other stress related diseases. It is an economic problem as well. Some calculations purport to show that the economic costs of health dangers exceed the economic benefit of.
Noise - Noise In general usage, noise can be considered sound without meaning; that is, sound that is not being used to transmit information, but is simply produced as a by-product of other activities. Most often it is defined as meaningless sound of greater than usual volume. Thus, a loud activity may be referred to as noisy. However, conversations of other people may be called noise for people not involved in any of them.

Insomnia - subtle level. Although they seem unscientific, many of these 'cures' are sufficient to break the insomnia cycle without the need for sedatives and sleeping tablets. Warm milk contains high levels of tryptophan, a natural sedative. Lavender oil and other relaxing essential oils may also be used to help induce a state of restfulness. The most commonly used class of hypnotics prescribed for insomnia are the benzodiazepines. This would include drugs such as diazepam, lorazepam, nitrazepam and midazolam. Removing probable causes of insomnia: Avoid all caffeine if you can't sleep. Caffeine is responsible for most cases of insomnia, including insomnia in night-shift workers. Caffeine is found in coffee, tea, yerba maté (Ilex paraguaiensis), guarana, cocoa, kola nut (this includes all cola drinks); it is also found in "pep-me-up" sodas like Red Bull.
Vocal loading - will then hit together more than 30 thousand times an hour. It is intuitively clear that the vocal fold tissue will experience some tiring due to this large amount of hits. Vocal loading includes also other kinds of strain on the speech organs. These include all kinds of muscular strain in the speech organs, similarly as usage of any other muscles will experience strain if used for an extended period of time. However, in respect of vocal loading research largest interest lies in stress exerted on the vocal folds. Effect of speaking environment Several studies in vocal loading show that the speaking environment does have a significant impact on vocal loading. Still, the exact details are debated. Most scientists agree on the effect of the following environmental properties air humidity -.
Ganzfeld experiment - cards), but rather could be any sort of picture, drawing, photograph, movie clip, piece of music, etc. Recent surveys and anecdotal reports over the centuries had indicated that spontaneous psi phenomena are frequently reported in states other than normal consciousness, such as dreaming, hypnosis, meditative states, etc. In the mid-1970s, from these reports several parapsychologists, Charles Honorton, William Braud, and Adrian Parker, independently hypothesized that psi signals may in fact be available most of the time, but are masked for most people by all the cognitive or environmental "noise" that we commonly experience during the normal conscious state, while the noise is reduced in these altered states, allowing better access to the psi signals. The "ganzfeld" or "total (sensory) field" experiments they developed aim to reduce such noise through a mild.
Economy of the Netherlands - which derives more than two-thirds of GDP from merchandise trade, had strongly positive balance of payments for 1999 estimated at $17.5 billion -- 4% of GDP, the main contributor to a current account surplus of close to 6% of GDP. Since there are no significant trade or investment barriers, the Netherlands remains a receptive market for U.S. exports and an important investment partner. The Netherlands is the eighth-largest U.S. export market, as well as the third-largest direct investor in the United States, behind the United Kingdom and Japan. Dutch accumulated direct investment in the United States in 1998 was $97 billion. The United States is the largest investor in the Netherlands with direct investment of $79 billion. There are more than 1,600 U.S. companies with subsidiaries or offices in the Netherlands..
Air pollution - the natural characteristics of the atmosphere. Some definitions also consider physical perturbations such as noise pollution, heat, radiation or light pollution as air pollution. Some definitions include the term harmful as a requisite to consider a change to the atmosphere as pollution. Table of contents showTocToggle("show","hide") 1 Causes 2 Contaminants 3 Further Reading 4 Sources Causes The sources of air pollution are divided in two groups: anthropogenic (caused by human activity) and natural. Natural sources include: Volcanic activity Dust from natural sources, usually large areas of land with little or no vegetation Gases, such as methane, emitted by the digestion of animals, usually cattle. Smoke from wildfires. Anthropogenic sources are mostly related to burning different kinds of fuel. They include: Dust and chemicals from farming, especially of erodible land, see Dust.
Boeing 2707 - have been built at the Boeing plant in Renton, Washington, but increasing outcry over the environmental effects of the aircraft, notably sonic boom, led to its cancellation in 1971 before the two prototypes had been completed. Boeing had been working on a number of small-scale studies on SST (SuperSonicTransport) designs since 1952, but set up a permanent research committee in 1958 which slowly grew to a $1 million effort by 1960. They proposed a number of alternative designs, all under the name Model 733. Most of their designs were built on the basis of a large delta wing, but in 1959 another design was offered as an offshoot of Boeing's efforts in the swing-wing TXF project (which led to the purchase of the General Dynamics F-111 instead of the Boeing offering)..
C-40 Clipper - ordered by the Navy to replace its fleet of aging C-9 Skytrainss. The C-40A is the first new logistics aircraft in 17 years to join the Naval Reserve. Currently, the Naval Reserve provides 100 percent of the Navy's worldwide in-theater medium and heavy airlift. The Clipper meets or exceeds international noise and environmental requirements that plague the current fleet of Naval Reserve C-9s. It is also more fuel-efficient and offers increased range and payload capabilities. The 737-700C aircraft is certified to operate in an all-passenger (121 passengers), all-cargo or combination ("combi") configuration that will accommodate up to three cargo pallets and 70 passengers on the main deck. The Navy purchased the airplanes using standard commercial practices, and ordered six of the 737-700C models. The first two of four aircraft were delivered.
Campaign for the Protection of Rural England - mentality" (i.e. "I've moved to the countryside but I don't want others to do likewise"), nostalgic rather than progressive, and conservative rather than ready to experiment. Large land-use change proposals such as for reservoirs, coal mines, quarries, airports or power stations are especially likely to arouse their anger. They can claim some credit for the slow shift of agricultural policies across Europe away from a price-support philosophy to one of environmental stewardship, a policy shift begun in England. Campaigns against noise and light pollution have been pursued over recent years and a greater understanding of the ecological and botanical impacts of these side-effects of urbanism is developing, indicating that they are not merely issues of aesthetics and residential amenity..
Corona discharge - mass between electrons and positively charged ions, and so only the electron having the ability to undergo a significant degree of ionising inelastic collision at common temperatures and pressures. An important reason for considering coronas is the production of ozone around conductors undergoing corona processes. A negative corona generates much more ozone than the corresponding positive corona. Applications of Corona Discharge Corona discharge has a number of commercial and industrial applications. Manufacture of ozone Scrubbing particles from air in air-conditioning systems Removal of unwanted volatile organics, such as chemical pesticides, solvents, chemical weapons agents, from the atmosphere Photocopying Air-ionisers perhaps benefitting health Kirlian photography is believed, by some, to be of use in visualising auras. Corona discharge is generally to be avoided in Power transmission, owing to loss of power in.
Total Quality Management - chosen. In that way, cheaper fixes can be substituted later, (say, when the produce is redesigned), with no loss of quality. After TQM has been in use, it's very common for parts to be redesigned so that critical measurements either cease to exist, or become much wider. It took people a while to develop tests to find emergent problems. One popular test is a "life test" in which the sample product is operated until a part fails. Another popular test is called "shake and bake." The product is mounted on a vibrator in an environmental oven, and operated at progressively more extreme vibration and temperatures until something fails. The failure is then isolated and engineers design an improvement. A commonly-discovered failure is for the product to come apart. If fasteners fail,.
Shoulder-Launched Multipurpose Assault Weapon - AN/PVS-4 night sights. The High Explosive, Dual Purpose (HEDP) rocket is effective against bunkers, masonry and concrete walls, and light armor. The High Explosive Anti-Armor (HEAA) rocket is effective against current tanks without additional armor. The 9mm spotting rounds are ballistically matched to the rockets and increase the gunner's first round hit probability. Training is accomplished with the MK7 Mod 0 encased common practice rocket and the MK213 Mod 0 noise cartridge. The SMAW MK153 Mod 0 launcher is based on the Israeli B-300 and consists of the launch tube, the spotting rifle, the firing mechanism, and mounting brackets. The launch tube is fiberglass/epoxy with a gel coat on the bore. The spotting rifle is a British design and is mounted on the right side of the launch tube. The firing.
Spike Milligan - Comedy shows 3 TV Comedy shows 4 Theatre 5 Movies 6 Books 7 Quotations 8 External Links Biography Spike Milligan suffered from bipolar disorder for most of his life, having at least ten breakdowns. He was a strident campaigner on environmental matters, particularly arguing against unnecessary noise. He served in the Royal Artillery in World War 2 in North Africa and also Italy, where he was hospitalized for shell shock. During most of the 30s and early 40s he performed as a jazz trumpeter but even then he did comedy sketches. After his hospitalisation he played guitar with a jazz/comedy group called The Bill Hall Trio, at first in concert parties for the troops and, after the War, for a short time on stage. While he was with the Central Pool.
Renewable energy - 'powerplants' for the next 4 billion years. Some renewable sources do not emit any additional carbon dioxide and do not introduce any new risks - like nuclear waste. Since they are harnessing relatively low-intensity energy this new kind of power plant needs to be distributed over a large area. To put the phrases 'low-intensity' and 'large area' easier to understand one should image that in order to produce 1000 kWh of electricity - a typical per-month-per-capita consumption of electricity in Western countries - a house owner in cloudy Europe needs to cover 10 square meters of roof with solar panels. The disadvantage of renewables is their impact on local environments and their visibility to everybody. Some people dislike the aesthetics of wind turbines or bring up nature conservation issues when it.

Quartz Oscillator - voltage signal from the resonator, amplifying it, and feeding it back to the resonator. The rate of expansion and contraction is the resonance frequency, and is determined by the cut and size of the crystal. The output frequency of a quartz oscillator is either the fundamental resonance or a multiple of the resonance, called an overtone frequency. A typical Q for a quartz oscillator ranges from 10^4 to 10^6. The maximum Q for a high stability quartz oscillator can be estimated as Q = 1.6 x 10^7/f, where f is the resonance frequency in MHz. Environmental changes of temperature, humidity, pressure, and vibration can change the resonance frequency of a quartz crystal, but there are several designs that reduce these environmental effects. These include the TCXO, MCXO, and OCXO. These designs.
Pollution - Pollution "Pollution" refers to harmful environmental contaminants and to the act or process of polluting the environment. Generally the process needs to result from human activity to be regarded as pollution. Even relatively benign products of human activity are liable to be regarded as pollution, if they precipitate negative effects later on. The nitrogen oxides and ozone produced by industry are often referred to as pollution, for example, although the substances themselves are not harmful. In fact, it is solar energy (sunlight) that converts these compounds to smog. Whether something is pollution can depend on context. Blooms of algae and the resultant eutrophication of lakes and coastal ocean is considered pollution when it is fueled by nutrients from industrial, agricultural, or residential runoff. Although carbon dioxide is not toxic—and actually.
Neil Young - 1969), which contained a similar mix of songs as his Buffalo Springfield contributions, and received mixed reviews. While a promising debut -- the track "The Loner" is still a staple of his live shows -- it remains a relatively weak set of songs compared to his latter output. Wanting a harder rock sound, Young recruited the band "The Rockets" (Danny Whitten, guitar; Billy Talbot, bass guitar; Ralph Molina, drums) and renamed them "Crazy Horse". Their album Everybody Knows This Is Nowhere (May 1969) -- credited to "Neil Young and Crazy Horse" -- was recorded in just two weeks, and is dominated by two lengthy jams, "Cowgirl in the Sand" and "Down by the River", which showcased the understanding between the musicians and Young's idiosyncratic guitar soloing. Crazy Horse, and Whitten in.
