The results of the study, based on collision integrals computed from the latest critically evaluated data on intermolecular forces in air, will be reported in the form of a table of viscosity, thermal conductivity, thermal diffusion, and diffusion coefficients at temperatures of 1,000 to 10,000 Af and of logarithm of pressure in atmospheres from Af to Af times normal density.

In the lower center rack an 8-channel recorder indicates the percentage of carbon dioxide and nitrogen from the upper and lower lobes of one lung, the total volume of inhalation per breath, the flow of air from both lobes, and the pressure of the two lobes with respect to each other.

For protein identification, fractions from the column were concentrated by pervaporation against a stream of air at 5-degrees-C or by negative pressure dialysis in an apparatus which permitted simultaneous concentration of the protein and dialysis against isotonic saline.

Then he heard it, like a muffled thud, felt a subtle change in air pressure.

As a result of having an actuator controlled precisely with air pressure via a servosystem, the movement is very fluid and there is very little noise.

For example, in sound recording, fluctuations in air pressure ( that is to say, sound ) strike the diaphragm of a microphone which induces corresponding fluctuations in the current produced by a coil in an electromagnetic microphone, or the voltage produced by a condensor microphone.

In fluids such as air and water, sound waves propagate as disturbances in the ambient pressure level.

The pieces are carefully heated with exclusion of air and then compressed into a uniform mass by intense hydraulic pressure ; the softened amber being forced through holes in a metal plate.

When a parcel of air descends, the pressure on the parcel increases.

When the pressure applied on a parcel of air decreases, the air in the parcel is allowed to expand ; as the volume increases, the temperature falls and internal energy decreases.

This improves accuracy by evening pressure buildups that would otherwise cause the arrow to " plane " on the air in a random direction after shooting.

The pieces are aligned and pressure is added to aid in adhesion and rid the bond of air bubbles.

The high pressure air below the lower surface of the wing moves around the wingtip towards the lower-pressure region on the upper surface, creating the vortex.

It might appear at first sight as though one connection would serve, but the differences in pressure on which these instruments depend are so minute, that the pressure of the air in the room where the recording part is placed has to be considered.

Thus if the instrument depends on the pressure or suction effect alone, and this pressure or suction is measured against the air pressure in an ordinary room, in which the doors and windows are carefully closed and a newspaper is then burnt up the chimney, an effect may be produced equal to a wind of 10 mi / h ( 16 km / h ); and the opening of a window in rough weather, or the opening of a door, may entirely alter the registration.

where is the cylinder pressure at bottom dead center which is usually at 1 atm, is the compression ratio, and is the specific heat ratio for the working fluid, which is about 1. 4 for air, and 1. 3 for methane-air mixture.

In 1705, it was noted that electrostatic generator sparks travel a longer distance through low pressure air than through atmospheric pressure air.

In 1857, German physicist and glassblower Heinrich Geissler sucked even more air out with an improved pump, to a pressure of around 10 < sup >− 3 </ sup > atm and found that, instead of an arc, the glow filled the tube.

He burst from the hot confinement of the room into the cold night air.

He could not grasp that Lord had withdrawn from the fight minutes ago, and that his leaden arms were flailing at nothing but the air.

Cool air moving slowly through the open or smashed-out side windows hinted of blooming roadside vegetation, and occasionally a faint fragrance of perfume swirled from the back seat.

Ramey's fist and the air expelled from the man's collapsing cheek made a hollow pop in the air like cupped hands clapping together.

A pervading quality of free lyricism and a building from turns close to the ground towards jumps into the air gives the work its central focus.

The figure leapt from the box, almost lost its balance, the flag draped there tore in the air, the figure landed on its left leg, fell on its hands, and pressed itself up.

a pile of wire cages for mice from his time as a geneticist and a microscope lying on its side on the window sill, vertical steel columns wired for support to the open ceiling beams with spidery steel cantilevers jutting out into the air, masonry constructions on the floor from the time he was inventing his disastrous fireplace whose smoke would pass through a whole house, visible all the way up through wire gratings on each floor.

There was an air of blindness in her gray eyes, the startled-horse look that ultimately comes to some women who are born at the end of an ancestral line long since divorced from money-making and which, besides, has kept its estate intact.

Another strategy -- bolder and tougher -- was also attracting notice in Washington: a naval and air blockade to cut Cuba off from the world, destroy Castro.

Home air conditioning has come a long way from the early days of overcooled theaters and the thermal shock they inflicted.

A relatively simple switching arrangement reverses the cycle so that the machine literally runs backward, and the heat is extracted from outdoor air and turned indoors.

Inflow of air from the surrounding atmosphere was prevented by the two disks shown in figure 2.

To reduce heat transfer from the hot gas to this anode holder outside the regime of the arc, a carbon shield was attached to the surface providing an air gap of 1/16 inch between the plate and the surface of the anode holder.

It was then distilled at least three times from a trap at -78-degrees to a liquid air trap with only a small middle fraction being retained in each distillation.

Theoretically, they are capable of extracting their required oxygen either from the surrounding air ( Ghoreyeb and Karsner, '13 ) or from pulmonary arterial blood ( Comroe, '58 ).

as he spoke I was reminded of the great bales of cargo which are swung, high in the air, from a docked steamship.

Spoilage by chemical action results from the reaction of one group of components in the food with others or with its environment, as in corrosion of the walls of metal containers or the reaction of fats with oxygen in the air to produce rancidity.

In this regard, close air support was provided in the form of the dive bomber and medium bomber.

There was, however, some suggestion that post dive fatigue is due to sub-clinical decompression sickness ( DCS ) ( i. e. micro bubbles in the blood insufficient to cause symptoms of DCS ); the fact that the study mentioned was conducted in a dry chamber with an ideal decompression profile may have been sufficient to reduce sub-clinical DCS and prevent fatigue in both nitrox and air divers.

Among the Selkups, the sea duck is a spirit animal because ducks fly in the air and dive in the water.

Even though it was independent from the surface for a very short duration, the Rouquayrol-Denayrouze apparatus reached worldwide celebrity after having been mentioned by Jules Verne in his adventure book Twenty Thousand Leagues Under the Sea ; but Jules Verne wildly exaggerated its dive duration without external air supply.

Fernez's goggles didn't allow a dive deeper than ten metres due to " mask squeeze ", so, in 1933, Le Prieur replaced all the Fernez equipment ( goggles, noseclip and valve ) by a full face mask, directly supplied with constant flow air from the cylinder.

New divers frequently consume all the air in a standard " aluminum 80 " cylinder in 30 minutes or less on a typical dive, while experienced divers frequently dive for 60 to 70 minutes at the same average depth, using the same capcity cylinder, as they have learned more efficient diving techniques.

A consequence of the higher loading in some tissues is that many decompression algorithms require deeper decompression stops than a similar decompression dive using air, and helium is more likely to come out of solution and cause decompression sickness following a fast ascent.

A player may sometimes perform a " dive ", i. e., throw his or her body in the air with a forward movement in an attempt to save the ball, and land on his or her chest.

In this fashion, if it is inadvertently rotated during the dive, it will only rotate so as to give a false reading of increased time below and thus less assumed tank air remaining rather than the opposite.

It is explained in Quidditch Through the Ages that the Quaffle is enchanted to fall very slowly through the air when dropped to prevent players from having to continuously dive to retrieve it.

The Saab B 17 dive bomber used the deployed undercarriage as an air brake.

Plunge diving allows birds to use the energy from the momentum of the dive to combat natural buoyancy ( caused by air trapped in plumage ), and thus uses less energy than the dedicated pursuit divers, allowing them to utilise more widely distributed food resources, for example, in impoverished tropical seas.

Also air combat tactics and doctrines changed, large scale strategic bombing campaigns were launched, fighter escorts introduced and the more flexible aircraft and weapons allowed precise attacks on small targets with dive bombers, fighter-bombers, and ground-attack aircraft.

When introduced these were almost exclusive to dive bombers, though the air brakes fitted to modern aircraft function in a similar manner.

This led to the famed Junkers Ju 87, and in turn, to many other air forces starting dive bomber efforts of their own.

However, the Skua sank the German cruiser Königsberg by dive bombing-the first time ever that a major warship was sunk in combat by air attack.

Since the times of World War I and into the interbellum, other classes of aircraft, light bombers, medium bombers, dive bombers, reconnaissance, fighters, fighter-bombers, could and did perform air strikes in the battlefield environment.

Functioning as CAG, O ' Hare was given command of the entire Enterprise air group: F6F fighters, SBD Dauntless dive bombers, TBF Avenger torpedo planes and 100 pilots.

Thereafter, a heavy air attack by sixty-seven enemy dive bombers was fought off with a total of seventeen enemy planes being destroyed ...

Then a large group of US dive bombers happened to find Nagumo's four carriers — with air cover absent.

To dive, the tanks are opened to allow air to exhaust out the top of the tanks, while the water flows in from the bottom.

To gain the full benefit, the user must purge the suit of air several times before each dive.
