Although there were only four fluids tested, it was apparent that there were two distinct types.

Two of the fluids showed a high-positive normal pressure when undergoing shear, and two showed small negative pressures which were negligible in comparison with the amount of the positive pressures generated by the other two.

These pathogens fall into two broad categories, bloodborne ( carried in the body fluids ) and airborne.

Du Fay announced that electricity consisted of two fluids: " vitreous " ( from the Latin for " glass "), or positive, electricity ; and " resinous ," or negative, electricity.

Microfluidic fuel cells can use laminar flow to separate the fuel and its oxidant to control the interaction of the two fluids without a physical barrier as would be required in conventional fuel cells.

* Stage V: Thirty-six to seventy-two hours after last dose: Increase in the above, fetal position, vomiting, free and frequent liquid diarrhea, which sometimes can accelerate the time of passage of food from mouth to out of system to an hour or less, involuntary ejaculation, which is often painful, saturation of bedding materials with bodily fluids, weight loss of two to five kilos per 24 hours, increased white cell count and other blood changes.

When two geometrically similar flow patterns, in perhaps different fluids with possibly different flow rates, have the same values for the relevant dimensionless numbers, they are said to be dynamically similar.

Pathogens fall into two broad categories, bloodborne ( carried in the body fluids ) and airborne.

In physics, a surface wave is a mechanical wave that propagates along the interface between differing media, usually two fluids with different densities.

In November 2006, in the midst of charges leveled at Taleyarkhan as regards his research standards, Dr. Edward R. Forringer and undergraduates David Robbins and Jonathan Martin of LeTourneau University presented two papers at the American Nuclear Society Winter Meeting that reported replication of neutron emission during a visit to the meta-stable fluids research lab at Purdue University.

The diaphragm is perforated in many places, enabling the exchange of fluids between the two cavities.

Natural convection will be more likely and / or more rapid with a greater variation in density between the two fluids, a larger acceleration due to gravity that drives the convection, and / or a larger distance through the convecting medium.

Anatomical pathology is one of two branches of pathology, the other being clinical pathology, the diagnosis of disease through the laboratory analysis of bodily fluids and tissues.

In 1830, Carl Friedrich Gauss, the German mathematician, unified the work of these two scientists to derive the Young – Laplace equation, the formula that describes the capillary pressure difference sustained across the interface between two static fluids.

In addition, Wren experimented on muscle functionality, hypothesizing that the swelling and shrinking of muscles might proceed from a fermentative motion arising from the mixture of two heterogeneous fluids.

In the clinical setting, there are two types of fluids that are used for intravenous drips: crystalloids and colloids.

The transfer of heat is accomplished without mixing the two fluids, which is desirable since the primary coolant might become radioactive.

Instead, they may represent two possible novel types of quantum fluids: " superconducting superfluids " and " metallic superfluids ".

In parallel-flow heat exchangers, the two fluids enter the exchanger at the same end, and travel in parallel to one another to the other side.

For efficiency, heat exchangers are designed to maximize the surface area of the wall between the two fluids, while minimizing resistance to fluid flow through the exchanger.

In the concurrent flow exchange mechanism, the two fluids flow in the same direction.

The result is thermal equilibrium: Both fluids end up at around the same temperature: 40 ° C, almost exactly between the two original temperatures ( 20 and 60 ° C ).

He crawled beneath the two supply wagons which stood between the buildings and peered around a corner.

They, and the two large fans which I could dimly see as daylight filtered through their vents, down at the far end of the hall, could be turned on by a master switch situated inside the office.

The only thing which would have attracted attention was that two wore the uniform of prison guards, three the striped suits of convicts.

The car was just about to us, its driver's fat, solemn face intent on the road ahead, on business, on a family in Sante Fe -- on anything but an old pick-up truck in which two human beings desperately needed rescue.

There had been a good second or two during which my muffler had been blowing out, and now I was certain I'd seen her somewhere before.

Johnny vigorously pounded two bleached steer bones against the gourd which served as his drum.

We followed the asphalt road for a few miles and then swung off onto a smaller road which was nothing more than two tire marks on the earth.

There were two rubbing sticks for making fire, two stones shaped roughly like knives, a woven-root container which held a few pounds of dried worms and the dead body of some rodent.

The one apparent connection between the two is a score of buildings which somehow or other have survived and which naturally enough are called `` historical monuments ''.

As for progress, the `` backward South '' can boast of Baton Rouge, which increased its population between 1940 and 1950 by two hundred and sixty-two percent, to 126,000, the second largest growth of the period for all cities over 25,000.

The Constitution of the Southern `` Confederation '' differed from that of the Federal Union only in two important respects: It openly, defiantly, recognized slavery -- an institution which the Southerners of 1787, even though they continued it, found so impossible to reconcile with freedom that they carefully avoided mentioning the word in the Federal Constitution.

They differed in the balance they believed essential to the sovereignty of the citizen -- but the supreme sacrifice each made served to maintain a still more fundamental truth: That individual life, liberty and happiness depend on a right balance between the two -- and on the limitation of sovereignty, in all its aspects, which this involves.

and it is surely clear that the first of these is the result of the way in which the individual's command of language interacts with the other two.

At the end of this period two pious Christians in Rome receive the revelation which leads them to seek the next Pope on the rock.

The colonel grunted, then made a remark which might be construed in either of two ways.

but the possibility of this effort is bound up with that development of historical thought which is the greatest achievement of our civilization in the last two centuries, and it is utterly impossible to people in whom this development has not taken place.

On Christmas Eve, students brought out two small Christmas trees which I placed on either side of the tent.

Office workers frequently go out there to lunch and swim during the siesta period, which, during the summer, lasts from two until five in the afternoon, when shops and offices are again open for business.

There is a mediocre restaurant at Sounion and I fed a thin little Grecian cat and gave it two saucers of water -- there was no milk -- which it lapped up as though it were nectar.

To document his charge, Pike set up two parallel columns in The Advocate showing the price charged by The Gazette and the considerably lower price for which the work could be done elsewhere.

Each will decide on his own course somewhere between these two extreme cases according to the sense of responsibility which is determined for him by the particular circumstances of his own life.

`` They straggle at such a rate '', he told the commander-in-chief, `` that if the enemy were enterprising, they might get two from us, when we would take one of them, which makes me wish General Howe would go on, lest any incident happen to us ''.

`` Tact '', by its very derivation, implies that its possessor keeps in touch with other people, but the author of Clericis Laicos and Unam Sanctam, the wielder of the two swords, the papal sun of which the imperial moon was but a dim reflection, the peer of Caesar and vice-regent of Christ, was so high above other human beings that he had forgotten what they were like.
