  Phase (matter) - Wikipedia, the free encyclopedia
Liquid crystals are another phase intermediate between solids and liquids; the molecules of such a substance have an orderly orientation and in some cases (that is, for smectic liquid crystals) even an orderly position in one direction, but are free to flow past one another.
In contrast, in the plasma phase the atoms are dissociated, i.e.
These phases are of great interest to astrophysics, because these high-pressure conditions are believed to exist inside stars that have used up their nuclear fusion "fuel", such as white dwarves and neutron stars.

 Lunar phase - Wikipedia, the free encyclopedia
In astronomy, a lunar phase is any of the aspects or appearances presented by the Moon as seen from Earth, determined by the portion of the Moon that is visibly illuminated by the Sun.
The lunar phases vary cyclically as the Moon orbits the Earth, according to the relative positions of the Earth, the Moon, and the Sun.
The phases are not created by the shadow of the Earth on the Moon (that would be a lunar eclipse); instead, they are a result of our seeing only part of the illuminated half of the Moon.

 Phases of the Moon and Percent of the Moon Illuminated   (Site not responding. Last check: 2007-10-21)
The phases of the Moon are related to (actually, caused by) the relative positions of the Moon and Sun in the sky.
During the crescent phases the percent illuminated is between 0 and 50% and during gibbous phases it is between 50% and 100%.
For practical purposes, phases of the Moon and the percent of the Moon illuminated are independent of the location on the Earth from where the Moon is observed.

 The Phases of the EUP
The primary goals of the Inception phase are to achieve stakeholder consensus regarding the objectives for the project and to obtain funding.
The goal of the Elaboration phase is to specify requirements in greater detail and to baseline the architecture for the system to be developed.
During this phase, the requirements as expanded from high-level features or a use case model to a more concrete form (usually system use cases and supplementary requirements such as business rules and technical requirements).

 Phases - Gas, liquid and solid
Each distinct form is called a phase, but the concept of phase defined as a homogeneous portion of a system, extends beyond a single material, because a phase may also involve several materials.
Phase is a concept used to explain many physical and chemical changes (reactions).
The concept of phase transition is also applied to the study of nuclear matter such as protons and neutrons.

During phases 5 through 8, the amount of light area decreases (or the darkened area increases) from right to left.
In the Southern Hemisphere the effect is just the opposite!) Astronomers use this to distinguish between the repeated phases of the moon by referring to the waxing or waning crescent, gibbous, and half phases.
(We do not observe phases of the outer planets because their orbits lie outside the orbit of the Earth and therefore they can never be between the Sun and the Earth.) There are two differences between the phasesof the Moon and the phases of Venus and Mercury, however.

 YPI - Periodization   (Site not responding. Last check: 2007-10-21)
The characteristics of a phase are that the over all goal of the training remains the same and that the tendency in the training load (up, down, level) remains consistent over the phase.
This phase is primarily designed to lower the accumulated fatigue level to as low a value as possible, while optimizing the race-readiness of the athlete.
This is a de-tuning phase, in which the training load and it's intensity is gradually lowered from the levels experienced in the competition phase.

Phase refinement requires an estimate of the protein phase, which is why it's better suited for the multiple derivative case, since SIR or SAS estimates alone are usually very poor.
The advantages of phase refinement are that in general, all parameters may be refined including native to derivative scaling parameters, and the corresponding weights (expected lack of closure estimates) are also implicitly "refined".
Phase refinement is however, sensitive to the hand of the heavy atom sets, and it is assumed that all input sets correspond to the SAME origin and hand.

 Project Phases
Phase transitions are ideal times to update planning baselines, to conduct high level management reviews, and to evaluate project costs and prospects.
The phases should be defined in terms of schedule and also in terms of specific accomplishments.
If project phases take place over many months or even years, it is vital to provide interim deliverables to give the customers and sponsors a sense that work is being accomplished, to provide an opportunity for feedback, and to capture project successes in documented form.

The key to understanding moon phases is: although the sun always shines on the same side of the moon, the moon is not always in the same place while orbiting Earth with respect to the sun.
Your job is to continue through all the phases, through (h), to determine if you can figure out which moon phase matches with the position on this diagram.
The waning phases of the moon are not as visible because the moon is not visible in the early evening when most people are out and about.
