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.

Figure 3 shows the data on a silicone fluid, labeled 12,500 cps which gave a high positive normal pressure.

When the heat release oscillations are in phase with the pressure oscillations, the Rayleigh Index is positive and the magnitude of the thermo acoustic instability is maximised.

The technique is very similar to the traditional column chromatography, except for that the solvent is driven through the column by applying positive pressure.

At low pressure, there was enough space between the gas atoms that the ions could accelerate to high enough speeds that when they struck another atom they knocked electrons off of it, creating more positive ions and free electrons in a chain reaction.

Its purpose is to achieve higher vacuum ( lower pressure ) than is possible by use of positive displacement pumps alone.

By exposing an azeotrope to a vacuum or positive pressure, it's possible to bias the boiling point of one component away from the other by exploiting the differing vapour pressure curves of each ; the curves may overlap at the azeotropic point, but are unlikely to be remain identical further along the pressure axis either side of the azeotropic point.

A unidirectional distillation will rely on a pressure change in one direction, either positive or negative.

To assist the lungs to distribute oxygenated blood throughout the body, infants at risk of hypoxia are often placed inside an incubator capable of providing continuous positive airway pressure ( also known as a humidicrib ).

::: the planing hull form is configured to develop positive dynamic pressure so that its draft decreases with increasing speed.

A positive displacement pump operating against a closed discharge valve will continue to produce flow and the pressure in the discharge line will increase, until the line bursts or the pump is severely damaged, or both.

Positive displacement pumps physically displace the fluid ; hence closing a valve downstream of a positive displacement pump will result in a continual build up in pressure resulting in mechanical failure of either pipeline or pump.

* Plenum chamber, a chamber intended to contain air, gas, or liquid at positive pressure

In addition, home oximetry may be equally effective in guiding prescription for automatically self-adjusting continuous positive airway pressure.

Unlike mammals, which use a breathing system driven by negative pressure, amphibians employ positive pressure.

Therefore, the vapor pressure will be greater than expected from the Raoult's law, showing positive deviation.

If the deviation is large, then the vapor pressure curve will show a maximum at a particular composition and form a positive azeotrope.

A positive vacuum energy density resulting from a cosmological constant implies a negative pressure, and vice versa.

If the energy density is positive, the associated negative pressure will drive an accelerated expansion of the universe, as observed.

( They are often termed " hot " and " cold ," and the AES14-1992 ( r2004 ) Standard EIA Standard RS-297-A suggest that the pin that carries the positive signal that results from a positive air pressure on a transducer will be deemed ' hot '.

Many noncoding DNA sequences have important biological functions as indicated by comparative genomics studies that report some regions of noncoding DNA that are highly conserved, sometimes on time-scales representing hundreds of millions of years, implying that these noncoding regions are under strong evolutionary pressure and positive selection.

He investigated its positive anti-bacterial effect on many organisms, and noticed that it affected bacteria such as staphylococci and many other Gram-positive pathogens that cause scarlet fever, pneumonia, meningitis and diphtheria, but not typhoid fever or paratyphoid fever, which are caused by Gram-negative bacteria, for which he was seeking a cure at the time.

Governments often tax and otherwise restrict the sale of goods that have negative externalities and subsidize or otherwise promote the purchase of goods that have positive externalities in an effort to correct the price distortions caused by these externalities.

This caused more than 50 years of positive economic, industrial, cultural and educational development in the Grand Duchy of Finland.

Some of these methods are denying the in-group ’ s harmful actions, denying responsibility, claiming actions by the in-group were just, focusing on positive aspects caused by the harmful action, and pointing out positive things in other areas to counterbalance the harm.

When considering the band structure and binding energy of a metal, it is necessary to take into account the positive potential caused by the specific arrangement of the ion cores – which is periodic in crystals.

The new system caused some controversy among fans, although third-party reviews were positive.

However, on March 26, 1983, the first test, known as the Cabra event, was performed in an underground shaft and resulted in marginally positive readings that could be dismissed as being caused by a faulty detector.

Since evil has no positive reality of its own, it cannot be caused to exist, and so God cannot be held responsible for causing it to exist.

# Education and accurate information about Vestibulodynia: Gynaecologist-led educational seminars delivered in a group format have a significant positive impact on psychological symptoms and sexual functioning in women who suffer from Provoked ( caused by a stimulus such as touch or sexual activity ) Vestibulodynia.

Since 1986 the stagnation in employment has led to a new inversion of the trend, caused not so much by an increase in the number of people leaving but by a fall in the number coming to live in the region, but in the 2000s ( decade ) net immigration has been positive again.

However, the increase in mouth ulcers and gum deterioration caused by chewing areca nut and betel may outweigh any positive effects.

In the presence of a higher than usual level of insulin ( generally caused by insulin resistance ), this down-regulation acts as a kind of positive feedback, increasing the need for insulin.

NiCd batteries are susceptible to failures caused by short circuiting due to dissolution / crystallization reactions occurring at the negative electrode, which can result in dendrite growth of Cd creating a short to the positive plate.

Extrapolation beyond is not linear since other failure modes, caused by decreasing charge acceptance resulting in positive electrode swelling and thermal instability, could control the battery life.

The bridge's movements were caused by a ' positive feedback ' phenomenon, known as synchronous lateral excitation.

Lewis tested positive for an elevated testosterone level that was caused by an over-the-counter supplement containing a substance banned by the league.

have posited that positive performance outcomes elicit pride in an individual when the event is appraised as having been caused by him alone.

The Neverhood received positive reviews, but was not a commercial hit, its release coinciding with the mid-1990s decline of adventure games that also caused the failure of other critically acclaimed games such as Grim Fandango.

* Hematologic: Hemolytic anemia ( direct Coombs test is positive ) and various cytopenias, and bleeding ( caused by thrombocytopenia ) can occur.

Though some criticized the school for inducting a student-athlete who caused their Final Four achievement to be vacated, others saw it as a positive recognition of one of the school's best ever athletes.

At the right, the lower trace shows a negative wave that corresponds to a current sink caused by positive charges entering cells through postsynaptic glutamate receptors, while the upper trace shows a positive wave that is generated by the current that leaves the cell ( at the cell body ) to complete the circuit.

This can be caused by a low or dead battery, by corroded or loose connections in the cable, or by a broken or damaged positive ( red ) cable from the battery.

offered insight into topics including the negative side effects of positive psychology, the negativity that can be found within the positive psychology movement and the current division inside the field of psychology caused by the differing opinions held by psychologists on positive psychology.
