* Helium at the Helsinki University of Technology ; includes pressure-temperature phase diagrams for helium-3 and helium-4

:* Thermodynamics, statistical mechanics, and physical chemistry, for phase equilibrium conditions, phase diagrams of materials systems ( multi-phase, multi-component, reacting and non-reacting systems )

The advent of X-ray diffraction and thermal analysis made it possible to study the structure of crystalline solids, including metals and their alloys, and the construction of phase diagrams became accessible.

Mole fraction is used very frequently in the construction of phase diagrams.

The results of such experiments can be plotted in phase diagrams.

These diagrams simplify and compress the details that would be repeated on each phase of a three-phase system, showing only one element instead of three.

Mineral physicists study the elastic properties of minerals ; their high-pressure phase diagrams, melting points and equations of state at high pressure ; and the rheological properties of rocks, or their ability to flow.

Triple points are points on phase diagrams where lines of equilibrium intersect.

The traces in the phase diagrams separate whenever the composition of the vapor differs from the composition of the liquid at the same temperature.

The ability to determine transition temperatures and enthalpies makes DSC a valuable tool in producing phase diagrams for various chemical systems.

This idea is used explicitly in the method for drawing phase diagrams.

Classic examples of phase diagrams from chaos theory are:

For instance, one can view the pressure-volume diagram or entropy-temperature diagrams as describing part of this phase space.

The symbol used to represent a gyrator in one-line diagrams ( where a waveguide or transmission line is shown as a single line rather than as a pair of conductors ), reflects this one-way phase shift.

Items that have different impedances for the different phase sequences are identified on the diagrams.

Data flow diagrams can be used in both Analysis and Design phase of SDLC.

Lattice proteins do not have genuine secondary structure ; however, some researchers have claimed that they can be extrapolated onto real protein structures which do include secondary structure, by appealing to the same law by which the phase diagrams of different substances can be scaled onto one another ( the theorem of corresponding states ).

Tempering imparts the steel its flexibility and toughness according to the phase diagrams for steel.

A DTA curve can be used only as a finger print for identification purposes but usually the applications of this method are the determination of phase diagrams, heat change measurements and decomposition in various atmospheres.

Ternary plots can also be used to create phase diagrams by outlining the composition regions on the plot where different phases exist.

For phase diagrams that do not possess gridlines, the easiest way to determine the composition is to set the altitude of the triangle to 100 % and determine the shortest distances from the point of interest to each of the three sides.

Later Helion wrote of this phase: `` For years I built for myself a subtle instrument of relationships -- colors and forms without a name.

the mere fact that he was selected, though as a substitute, to act as interlocutor or moderator for it, or perhaps we should say with Buck as ' father of the act ', is in itself a difficult phase of his development to grasp.

Perhaps, in that short piece or letter written to Hartlib in which he sketched his scheme for educating young men, he merely overlooked that phase of their exercises.

The basic mapping phase of the program has been completed and the inventory phase is scheduled for completion July 1, 1961.

The Armed Forces Epidemiological Board agreed to submit each month a report for one of its 12 commissions, so that each commission will report once a year on some phase of its work calculated to be of particular interest and value to medical officers of the Armed Forces.

The contents of the manifold for liquid phase experiments were then mixed by shaking, redistributed to the reaction tubes, frozen down, and each tube was then sealed off.

The reactants for the gas phase experiments were first frozen out in a side-arm attached to the manifold and then allowed to distil slowly into the manifold of pre-cooled reaction cells before sealing off.

-- The samples for liquid phase thermal reaction studies were prepared in Pyrex capillary tubing 2.5 mm. i.d. and about 15 cm. long.

-- Although there was some variation in results which must be attributed either to trace impurities or to variation in wall effects, the photochemical exchange in the gas phase was sufficiently reproducible so that it seemed meaningful to compare the reaction rates in different series of reaction tubes for the purpose of obtaining information on the effect of chlorine concentration and of carbon tetrachloride concentration on the reaction rate.

Another great danger is that the emerging middle class will feel itself increasingly alienated from the political leaders who still justify their dominance by reference to the struggle for independence or the early phase of nationalism.

Needless to say, strong hands are not eager to be joined by weak hands, for this increases the risk that they will have to absorb what these weak hands unload on the way up, at higher prices, during the run-up phase of the campaign.

When served in a psychological atmosphere that allows young bodies to assimilate the greatest good from what they eat because they are free from tension, a foundation is laid for a high level of health that releases the children from physical handicaps to participate with enjoyment in the work assignments, the athletic programs and the most important phase, the educational opportunities.

In other words, the promulgators of the murder plan made clear that physically exterminating the Jews was but an extension of the anti-Semitic measures already operating in every phase of German life, and that the new conspiracy counted on the general anti-Semitism that had made those measures effective, as a readiness for murder.

As for food, Mrs. Henry Louchheim, chairman of this phase, is a globetrotter who knows good food.

For adaptation to a water phase, prolactin is the required hormone, and for adaptation to the land phase, thyroxine.

Each of these stages includes the risk of interference in case the degree of phase transfer is different for the analyte in the calibration standard and in the sample.

Cuyp was one of the first Dutch painters to appreciate this new leap forward in style and while his own Both-inspired phase was quite short ( limited to the mid 1640s ) he did, more than any other contemporary Dutch artist, maximize the full chromatic scale for sunsets and sunrises.

RG1678 has been shown in phase 2 clinical trials to be selectively effective for the negative symptoms of schizophrenia.

The term byte was coined by Dr. Werner Buchholz in July 1956, during the early design phase for the IBM Stretch computer.

The saturation temperature is the temperature for a corresponding saturation pressure at which a liquid boils into its vapor phase.

This means that for every feature that one sees in the frequency response of the analog filter, there is a corresponding feature, with identical gain and phase shift, in the frequency response of the digital filter but, perhaps, at a somewhat different frequency.
