Years are usually counted from a particular starting point, usually called the epoch, with era referring to the particular period of time ( Note the different use of the terms in geology ).

These polar unit vectors can be expressed in terms of Cartesian unit vectors in the x and y directions, denoted i and j respectively :< ref > Note: unlike the Cartesian unit vectors i and j, which are constant, in polar coordinates the direction of the unit vectors u < sub > r </ sub > and u < sub > θ </ sub > depend on θ, and so in general have non-zero time derivatives .</ ref >

Note, however, that it is acceptable to define two relative terms in respect of each other.

Note also that the terms are not always treated as mutually exclusive ; there is not necessarily anything contradictory in the statement that " the language of the Pennsylvania Dutch is a dialect of German ".

( Note that we are imagining the vector field to be like the velocity vector field of a fluid ( in motion ) when we use the terms flow, sink and so on.

Note that while the terms demon and demonic are used in monotheistic faiths as antonyms to divine, they are in fact derived from the Greek word daimón ( δαίμων ), which itself translates as divinity.

Note that the terms constructive and critical are used to refer to aspects of deistic thought, not sects or subtypes of deismit would be incorrect to classify any particular deist author as " a constructive deist " or " a critical deist ".

Note that these arguments may indeed have validity, but they require some independent justification of the connection between their terms: otherwise the argument ( as a logical tool ) remains fallacious.

Note that the terms < tt > x </ tt > and < tt > y </ tt > aren't alpha-equivalent, because they are not bound in a lambda abstraction.

Note that the terms prenasalization and postnasalization are normally used only in languages where these sounds are phonemic: that is, not analyzed into sequences of stop plus nasal.

Note that some mathematical literature uses different definitions for the term " completely regular " and the terms involving " T ".

Note that the re-visiting policies considered here regard all pages as homogeneous in terms of quality (" all pages on the Web are worth the same "), something that is not a realistic scenario, so further information about the Web page quality should be included to achieve a better crawling policy.

Note: The equivalent noise resistance in terms of the mean-square noise-generator voltage, e < sup > 2 </ sup >, within a frequency increment, Δ f, is given by

Note that the axioms are given in terms of the maps ( binary product, unary inverse, and nullary identity ), hence are categorical definitions.

( Note that " falling " and " rising " in this context do not refer to vowel height ; the terms " opening " and " closing " are used instead.

: Note: For ease of understanding, this discussion uses the terms intersection, road and map — however, formally these terms are vertex, edge and graph, respectively.

Note that, as an asymptotic expansion, this series is not convergent: it is a reasonable approximation only if the series is truncated at a finite number of terms, and only large values of x are employed.

Note that this is stated in terms of maps – product and inverse must be maps in the category – and without any reference to underlying " elements " of group – categories in general do not have elements to their objects.

Note that for large enough n, only the first and second terms are not converging to zero, so we get an asymptotic expression:, as.

Note: The listed measurements of this system range from the lowest to highest acceptable halachic value, in terms of conversion to either metric or Imperial units.

Note that of the above list of strategic terms, even this elementary summary indicates that the Mongols strategy was directed towards an objective ( that schwerpunkt ( main focus ) being nothing less than the psychology of the opposing population ) achieved through the offensive ; the offensive was characterized by concentration of forces, manoeuvre, surprise and simplicity.

Note that if the terms were swapped around in the first co-premise or if the first premise was rewritten to " Only Zs and Ys can be Bs " then it would no longer be a fallacy, although it could still be unsound.

Note that sometimes different terms are used to describe the corresponding supervised and unsupervised learning procedures for the same type of output.

Note that this pressure increase is more than a simple 10: 1 compression ratio would indicate ; this is because the gas is not only compressed, but the work done to compress the gas has also heated the gas and the hotter gas will have a greater pressure even if the volume had not changed.

Note that the beryllium scale is inverted, so increases on this scale indicate lower < sup > 10 </ sup > Be levels

Note that the '-' and '-' prefixes do not indicate the direction of rotation of polarized light, which is a combined effect of the arrangement at all chiral centers.

Note 3: The DTG may indicate either the date and time a message was dispatched by a transmitting station or the date and time it was handed into a transmission facility by a user or originator for dispatch.

Note: Party allegiances as shown here indicate party membership before the dissolution of all political parties apart from the NSDAP.

Note that the ' II_ ' prefix does not indicate that these are for the ' II ' installation.

( Note: The numbers appended to the names of Lane family members indicate the generation number beginning with Job Lane ( 1 ), who immigrated from Rickmansworth, England.

Note that the frequency of this condition does not indicate the true prevalence of chimerism.

Note: Dates indicate original year of release.

Note that Pinyin uses the caron, not the breve, to indicate the third tone of Mandarin Chinese ; the breve cannot be used as a substitute in computer environments because Unicode does not provide an equivalent of ǚ with a breve.

Note that a GPS receiver on a ship may, during the course of a long voyage, indicate height variations, even though the ship will always be at sea level ( tides not considered ).

Note the ruffled feathers on top of the wings indicate that the swan is flying at the Stall ( flight ) | stall ing speed.

: Note: Years in parentheses indicate the time of service as a priest of the Archdiocese of Los Angeles, prior to appointment to the episcopacy.

: Note: Years in parentheses indicate the time of service as a priest of the Archdiocese of Philadelphia, prior to appointment to the episcopacy.

:: Note: The subscripts outside the parenthesis indicate which variables are being held constant during differentiation.

Note that in some of the countries mentioned below it is unusual to indicate a former queen-consort as a dowager.

Note stripes which indicate movement.

Note: The word " prohibited " is a classification and does not indicate that such firearms are " prohibited " as per the normal use of the word.

League positions since the 1920 – 21 season. Note – Dotted horizontal lines indicate league divisions.

Note that some languages have what are described as " relative pronouns " ( in that they agree with some properties of the head noun, such as number and gender ) but which don't actually indicate the case role of the shared noun in the embedded clause.

Note that such a perpetual calendar fails to indicate the dates of moveable feasts such as Easter, which are calculated based on a combination of events in the Tropical year and lunar cycles.

* Finest TGF OP-highest quality grade ( Note: " Special " is occasionally substituted for " Finest ", with a number 1 at the end to indicate the very finest ), often hand processed and produced at only the best plantations, roughly one quarter tips

Note: The brackets indicate substitute words that may or have been sung instead of the word in front of them.
