Predictions of a future maximum's timing and strength are very difficult ; predictions vary widely.

Predictions of the force were later extended to finite-conductivity metals and dielectrics by Lifshitz and his students, and recent calculations have considered more general geometries.

Predictions have been made that more than 40 % of the animal and plant species in Southeast Asia could be wiped out in the 21st century.

Predictions for the Moon's Leonid impacts also noted that in 2000 the side of the Moon facing the stream was away from the Earth but that impacts should be in number enough to raise a cloud of particles kicked off the Moon by impacts would cause a detectable increase in the sodium tail of the Moon.

Predictions such as are routinely used within Kalman filters and smoothers to estimate current and past signal values, respectively.

Music, the Arts, and Ideas: Patterns and Predictions in Twentieth-Century Culture, second edition.

Predictions of quantum mechanics have been verified experimentally to an extremely high degree of accuracy.

Predictions tools made significant progress during the decade, UN-sponsored organisations such as the IPCC gained influence, and studies such as the Stern report influenced public support for paying the political and economic costs of countering climate change.

Predictions of similar increases in computer power had existed years prior.

* Predictions have been made for commercial hypersonic air travel by 2050.

: " The previously unrelased track " Predictions of Fire " which Laibach readily contributed to this compilation functioned in an early version as background to a 1994 speech of the NSK philosopher Peter Mlakar and is followed by an ecstatic dance orgy.

Predictions from both these theories have been confirmed in different experimental contexts, with no theory winning outright.

The Sub-bureau for Rapid Service and Predictions of Earth Orientation Parameters of the IERS, located at the United States Naval Observatory, monitors the Earth's rotation.

Predictions of the neoliberalism were extended to these six countries in four areas: urban systems and primacy, urban unemployment and informal employment, urban inequality and poverty, and urban crime and victimization.

Predictions from reliable sources have been used for these elements.

The NSK were the subject of a 1996 documentary film written and directed by Michael Benson, entitled Prerokbe Ognja in Slovenian, or Predictions of Fire in English.

Numbers, Predictions, and War.

Predictions vary, including race war or a Jewish-backed United Nations takeover of the USA and endorse physical struggle against what they see as the forces of evil.

Predictions not sufficiently specific to be tested are similarly not useful.

** The Accomplishment of the First of Mr. Bickerstaff's Predictions ( together, part of the " Bickerstaff Papers ")

Predictions must also be reliable, as false alarms and cancelled alarms are not only economically costly, but seriously undermine confidence in, and thereby the effectiveness of, any kind of warning.

Predictions that came close ( but given a probability of only 30 %) had ten or twenty year windows.

The NSK were the subject of a 1996 documentary film written and directed by Michael Benson, entitled Prerokbe Ognja in Slovenian, or Predictions of Fire in English.

Predictions have often been made, from antiquity until the present, by using paranormal or supernatural means such as prophecy or by observing omens.

In the United States, nitrogen oxides, PM, carbon monoxide, sulphur dioxide, and ozone, are regulated as criteria air pollutants under the Clean Air Act to levels at which human health and welfare are protected.

The chemical processes that affect the removal are dependent on the ability of atmospheric chemistry to oxidize the smoke, via reactions with oxidative species such as ozone and nitrogen oxides, both of which are found at all levels of the atmosphere.

Since stratospheric ozone is produced by solar UV radiation, one might expect to find the highest ozone levels over the tropics and the lowest over polar regions.

The same argument would lead one to expect the highest ozone levels in the summer and the lowest in the winter.

The observed behavior is very different: most of the ozone is found in the mid-to-high latitudes of the northern and southern hemispheres, and the highest levels are found in the spring, not summer, and the lowest in the autumn, not winter in the northern hemisphere.

Even though ozone in the lower tropical stratosphere is produced at a very slow rate, the lifting circulation is so slow that ozone can build up to relatively high levels by the time it reaches.

Hospital admissions and respiratory deaths often increase during periods when ozone levels are high.

However, the ozone hole is most usually measured not in terms of ozone concentrations at these levels ( which are typically of a few parts per million ) but by reduction in the total column ozone, above a point on the Earth's surface, which is normally expressed in Dobson units, abbreviated as " DU ".

The Antarctic ozone hole is an area of the Antarctic stratosphere in which the recent ozone levels have dropped to as low as 33 % of their pre-1975 values.

Since the ozone layer absorbs UVB ultraviolet light from the sun, ozone layer depletion is expected to increase surface UVB levels, which could lead to damage, including increase in skin cancer.

Correspondingly, a decrease in atmospheric ozone is expected to give rise to significantly increased levels of UVB near the surface.

When a laser printer or copier is operated for a long period of time in a small, poorly ventilated space, these gases can build up to levels at which the odor of ozone or irritation may be noticed.

Since 1972 it has measured a variety of atmospheric and climatic phenomena, including the levels of ozone, nitric oxide, sulphur dioxide and various hydrocarbons in the atmosphere as well as meteorological data such as the levels of temperature, dew point, relative humidity, pressure, wind, global and direct irradiance.

Formation of tropospheric ozone is only possible in presence of high levels of NO < sub > x </ sub >, which comes almost exclusively from industrial activities.

In fact, isoprene can have the opposite effect and quench ozone formation under low levels of NO < sub > x </ sub >.

Telecommuting gained ground in the United States in 1996 after " Clean Air Act amendments were adopted with the expectation of reducing carbon dioxide and ground-level ozone levels by 25 percent.

When ozone levels are high, more people with asthma have attacks that require a doctor's attention or use of medication.
