Unlike proper motion, a star's radial velocity cannot be directly observed, but must be determined through measurement of the spectrum.

Due to the constant, and unvarying speed of light ( that is also constant ; without regard to whatever is the velocity of the eminating or reflecting source ), the true ( i. e., instantaneous ) velocities of distant stars cannot be observed ; the observed proper motion reflects the motion ( velocity ) of a star at the time the light was emitted from that source.

Current linguistics makes a distinction between proper nouns and proper names ; but this distinction is not universally observed, and sometimes it is observed but not rigorously.

If the relative velocity between an observer ( or his measuring instruments ) and the observed object is zero, then the proper length of the object can simply be determined by directly superposing a measuring rod.

Amasis, however, reportedly treated Apries ' mortal remains with respect and observed the proper funerary rituals by having Apries ' body carried to Sais and buried there with " full military honours.

While there is still some debate on the need to deposit actual killed individuals as type specimens, it can be observed that given proper vouchering and storage, tissue samples can be just as valuable even in case disputes about the validity of a species arise.

Both beams recombine at point C ' to produce an interference pattern ( assuming proper alignment ) visible to the observer at point E. To the observer at point E, the effects observed would be the same as those produced by placing surfaces A and B ' ( the image of B on the surface M ) on top of each other.

The researchers observed the " Lomonosov's arc " and other aureole effects due to Venus's atmosphere and concluded that Lomonosov's telescope was fully adequate to the task of detecting the arc of light around Venus off the Sun's disc during ingress or egress if proper experimental techniques as described by Lomonosov in his 1761 paper are employed.

The lifeboat Northumberland, pulled by the Ramsgate steam tugboat Aid began to make a rescue attempt, but the boatmen and harbor tug men were prevented from leaving the harbor by the harbormaster, because he had not received the distress call by the proper means, and regulations had not been observed.

This can result in false negatives on an antibody test if the proper waiting period is not observed after completion of medications.

Certain specific features to be observed in a concelebrated Mass are noted in their proper place.

They were to visit the churches regularly, to see that the services were duly ministered, the vessels and vestments are in proper order, the canon of the mass correctly observed and distinctly read, as also the ‘' hours ’’.

In 1914, R. Furuhjelm observed that the spectroscopic binary mentioned above had a faint companion star, which, as its proper motion was similar to that of the spectroscopic binary, was probably physically bound to it.

By comparing reaction cells sealed from the same manifold temperature dependency corresponding to activation energies ranging from 11 to 18 Af was observed while dependence on the first power of the light intensity seemed to be indicated in most cases.

Thus, the planetary model of the atom was discarded in favor of one that described atomic orbital zones around the nucleus where a given electron is most likely to be observed.

Galileo used smaismrmilmepoetaleumibunenugttauiras for Altissimum planetam tergeminum observavi (" I have observed the most distant planet to have a triple form ") for discovering the rings of Saturn in 1610.

Haplogroups D1a, M7a, and N9b were observed in these individuals, and N9b was by far the most predominant.

As freedom of expression or movement is the objective, the most appropriate responses cannot be anticipated, but are observed and chosen in the moment.

Originally based on the date used to calculate the age of fruit trees for tithing as mandated in Leviticus 19: 23 – 25, the holiday now is most often observed by planting trees, or raising money to plant trees.

The most investigated example is represented by thin multicrystalline silicon films, where such as the unoriented molecule. An initial amorphous layer was observed in many studies.

The effort has focused on changes observed during the period of instrumental temperature record, when records are most reliable ; particularly on the last 50 years, when human activity has grown fastest and observations of the troposphere have become available.

Some birds, especially corvids and parrots, are among the most intelligent animal species ; a number of bird species have been observed manufacturing and using tools, and many social species exhibit cultural transmission of knowledge across generations.

This places a limit or a past horizon on the most distant objects that can be observed.

The lighting of a community Beltane fire from which each hearth fire is then relit is observed today in some parts of the Gaelic diaspora, though in most of these cases it is a cultural revival rather than an unbroken survival of the ancient tradition.

The energy gap is most directly observed in tunneling experiments and in reflection of microwaves from superconductors.

As a result, vegetation forms predicted by conventional biome systems are rarely observed across most of Earth's land surface.

During Charles Darwin's studies on the Galápagos Islands, Darwin observed 13 species of finches that are closely related and differ most markedly in the shape of their beaks.

They have moved into most of the areas of North America formerly occupied by wolves, and are often observed foraging in suburban garbage bins.

The most observed geometries are listed below, but there are many cases that deviate from a regular geometry, e. g. due to the use of ligands of different types ( which results in irregular bond lengths ; the coordination atoms do not follow a points-on-a-sphere pattern ), due to the size of ligands, or due to electronic effects ( see, e. g., Jahn-Teller distortion ):

The most frequently observed problems related to an AVM are headaches and seizures while at least 15 % of the population at detection have no symptoms at all.

In other cases, severe deviations from Raoult's law and Dalton's law are observed, most famously in the mixture of ethanol and water.

Though the theory of dark matter remains the most widely accepted theory to explain the anomalies in observed galactic rotation, some alternative theoretical approaches have been developed which broadly fall into the categories of modified gravitational laws and quantum gravitational laws.

Rapidly moving electrons are most sharply accelerated when they encounter a region of force, so they are responsible for producing much of the highest frequency electromagnetic radiation observed in nature.
