Since controlled burns are often done during relatively high humidity levels ( on the grounds that they could not be safely contained during periods of very low humidity ), the driptorch is more effective and more often used.

Since outside temperatures can possibly range from-40 ° C (- 40 ° F ) to 46 ° C ( 115 ° F ), with varying degrees of solar loading, along with humidity levels ranging from below 10 % up to 100 %, significant environmental stresses within the enclosure or facility can be produced.

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.

Since the humidity was only 11 %, the rain evaporated so that " only a trace of precipitation was recorded in the rain gauge ".

Since warmer air frequently contains more water vapor than colder air, this mixing will usually also transport water vapor into the air near the surface, causing the relative humidity of the near-surface air to increase.

Since high humidity is associated with increased mould growth, allergic responses, and respiratory responses, the presence of additional moisture from houseplants may not be desirable in all indoor settings.

Since the katabatic winds are descending, they tend to have a low relative humidity which desiccates the region.

Since the air supply is pre-cooled in the first stage, less humidity is transferred in the direct stage, to reach the desired cooling temperatures.

Since this technique is used to determine the water content of samples, atmospheric humidity could alter the results.

Since it is usually installed on the bow deck of warships, these turrets are often exposed to breaking waves and humidity.

Since the Pattani site abuts the sea, very high humidity and sea water vapor would lead to prohibitive maintenance cost for the upkeep of the engineering laboratory equipment and engineering teaching facilities.

Since for each n this removes intervals adding up to at most 1 / 2 < sup > n + 1 </ sup >, the nowhere dense set remaining after all such intervals have been removed has measure of at least 1 / 2 ( in fact just over 0. 535 ... because of overlaps ) and so in a sense represents the majority of the ambient space.

Since photosynthesis is also limited by ambient carbon dioxide levels, light curves are often repeated at several different constant carbon dioxide concentrations.

Since the boiling point of a solvent is the temperature at which the vapor pressure of the solvent is equal to the ambient pressure, reducing pressure in the tower has the effect of lowering the boiling point of the solvent.

Since the pressure on top of the engine is ambient, this means that base gives no overall thrust ( but it also means that this part of the nozzle doesn't lose thrust by forming a partial vacuum, thus the base part of the nozzle can be ignored at low altitude ).

Since development is highly predictable if the ambient temperature is known, blow-flies are considered a valuable tool in forensic science.

Since a PPTC device has an inherently higher resistance than a metallic fuse or circuit breaker at ambient temperature, it may be difficult or impossible to use in circuits that cannot tolerate significant reductions in operating voltage, forcing the engineer to choose the latter in a design.

Since the direction of the ambient light is rarely constant for a shooter, the resulting changing glare can significantly affect the point of aim.

Since ambient hum from power-supply transformers, radio frequencies, or electrical devices reaches the coils as common-mode noise, it induces an electrical current of equal magnitude in each coil.

Since the mid-1990s, Harris has worked primarily in electronic and ambient music, his main projects being Scorn and Lull.

Since the sound easily stands out against other forms of music or ambient noise due to its uniqueness, it is usually muted by creative use of a DJ mixer.

The song begins with a nearly acapella section, in which Björk sings the line " Since I met you / this small town / hasn't got room ", underscored only by ambient sounds.

Since SSC is a form of hydrogen embrittlement, it is most susceptibile to cracking at or slightly below ambient temperature.

Since all surface Si atoms are fully co-ordinated, hydrogen termination leads to enhanced stability in ambient environments unlike a ' clean surface ' having unpassivated surface atoms, or dangling bonds.

Since these devices look like personal stereo " earbuds ", they can be worn unobtrusively and are especially useful for making " audience " recordings of concerts and other live events, or for recording " ambient " sounds ( such as birdsong, or traffic noises, or crowd sounds ) with a realistic three-dimensional soundfield, which can later be mixed in together with more conventional recordings.

Since Nordström's equation of motion for test particles in an ambient gravitational field also follows from a Lagrangian, this shows that Nordström's second theory can be derived from an action principle and also shows that it obeys other properties we must demand from a self-consistent field theory.

Since the cardioid polar pattern rejects off-axis sound, less of the ambient room characteristics are picked up.

Since the air is a continuum, the network of communication remains intact regardless of the positions or motions of the points ( the people ) in the net.

Since 1957, more and more trans-Atlantic passengers have been crossing by air.

Since effective area coverage appears fairly remote, the requirement can be borne in mind while considering the elements: air, surface, sub-surface, fixed installations, mines, and intelligence.

Since the air on the top of the wing is traveling faster than on the bottom, due to Bernoulli effect, at speeds close to the speed of sound the air on the top of the wing will be accelerated to supersonic.

Since the last railway was dismantled in 1952, the only remaining modes of transport are by motorways, by sea, and by air.

The event temporarily warmed air temperature by 1. 5 ° C, compared to the usual increase of 0. 25 ° C associated with El Niño events .< ref name =" Trenberth "> Since then, mass coral bleaching has become common worldwide, with all regions having suffered " severe bleaching ".

Since World War I, achieving and maintaining air superiority has been essential for victory in conventional warfare.

Since air and water are governed by similar fluid equations, albeit with vastly different levels of viscosity, density, and compressibility, the hydrofoil and airfoil create lift in identical ways ( see foil ( fluid mechanics )).

Since then, " Sang real " is sometimes employed to lend a medievalising air in referring to the Holy Grail.

Since air is plentiful at the surface of the earth, the oxidizer is typically atmospheric oxygen, which has the advantage of not being stored within the vehicle.

Since air is an insulator, in principle no other substance is needed to keep power where it should be.

Since the early 1940s, Kingman Reef has had very little human contact, though amateur radio operators from around the world have occasionally visited the reef to put it " on the air " in what is known as a DX-pedition.

Since the Treaty of Versailles forbade Germany to have an air force, German pilots trained in violation of the treaty in secret.

Since the foil must exert a force on the air to change its direction, the air must exert a force of equal magnitude but opposite direction on the foil.

Since the enactment of EU legislation concerning the concentration of particulate in the air, environmental groups such as Greenpeace have staged large protest rallies to urge the city council and the State government to take a harder stance on pollution.

Since nori sheets easily absorb water from the air and degrade, a desiccant is indispensable when storing it.

Since January 2006, the NATO International Security Assistance Force undertook combat duties from Operation Enduring Freedom in southern Afghanistan, the NATO force chiefly made up of British, Canadian and Dutch forces ( and some smaller contributions from Denmark, Romania and Estonia and air support from Norway as well as air and artillery support from the U. S .) ( see the article Coalition combat operations in Afghanistan in 2006 ).

Since the early 1980s, an elegant solution has been the near-frictionless air bearing linear arm which requires no tracking drive mechanism other than the record groove itself.

Since January 2012, four daytime soap operas – General Hospital, Days of our Lives, The Young and the Restless, and The Bold and the Beautiful – continue to air on the three major networks, down from 12 in 1990 – 91 and a high of 19 in 1969 – 70.

Since the wing exerts a force on the air to change its direction, the air must exert a force on the wing, equal in size but opposite in direction.

Since neutrons are absorbed by air, even a high-yield neutron bomb is not able to radiate neutrons beyond its blast range and so would theoretically have no destructive advantage over a normal hydrogen bomb.
