Therefore, equatorial coordinates ( including declination ) are inherently relative to the year of their observation, and astronomers specify them with reference to a particular year, known as an epoch.

Therefore, at Rebekah's urging, Jacob flees to a distant land to work for a relative, Laban ().

Therefore, on timescales of thousands of years or more ( still tiny by astronomical standards ), their relative position is effectively random.

Therefore it may be necessary to adopt more precise methods of calculating potency based upon observations of relative, but not necessarily equal effects, likewise, statistical methods may also be employed.

Therefore in terms of the true gain ( relative to an isotropic radiator ) G, this figure for the gain is given by:

Therefore, even though the relative geometry of the Earth-Sun-Moon system will be nearly identical after a saros, the Moon will be in a different position with respect to the stars.

Therefore, it is often implemented differentially as differential pulse-position modulation, whereby each pulse position is encoded relative to the previous, such that the receiver must only measure the difference in the arrival time of successive pulses.

Therefore, the relative position vector remains bounded, having its smallest magnitude at periapsis r < sub > p </ sub > which is given by:

Therefore, collectively, expenditure on luxury goods and services ( positional goods ) is an economic loss, like competitive military spending ( an arms race ) — wherein each country must match the military expenditures of other countries in the arms race, or suffer a loss of relative military power.

Therefore a change in relative humidity can be explained by a change in system temperature, a change in the absolute pressure of the system, or change in both of these system properties.

Therefore, Spencer concluded, religion and science agree in the supreme truth that the human understanding is only capable of ' relative ' knowledge.

Therefore, despite relative proximity to the mainland, the islands are listed with the New Zealand Outlying Islands.

Therefore, cool storage ( above freezing ) is more common and less costly, which requires that the temperature is consistently between with 30 – 40 % relative humidity with special attention to dew point to eliminate concerns for condensation.

Therefore, by analysing the different frequencies of light emitted in fluorescent spectroscopy, along with their relative intensities, the structure of the different vibrational levels can be determined.

Therefore, a Fischer projection cannot be rotated by 90 ° or 270 ° in the plane of the page or the screen, as the orientation of bonds relative to one another can change, converting a molecule to its enantiomer.

Each time g changes in this procedure, it gets strictly smaller relative to the partial lexicographic order on polynomials where h > h ' iff the largest monomial which is in exactly one of h and h ' is in h. Therefore this process will eventually terminate.

Therefore, the case we have been considering is a marginal case ; if the relative humidity of the ambient air were even a bit higher ( with the total pressure and temperature remaining as above ), then the local dew point inside the vortices would rise, while the local temperature would remain the same as what we have just found.

Therefore an intrinsic equation defines the shape of the curve without specifying its position relative to an arbitrarily defined coordinate system.

Therefore, bees that follow the waggle run of the dance are still correctly led to the food source even though its angle relative to the sun has changed.

# Therefore ( relative to these premises ) it is probable ( to the degree p < sub > 1 </ sub > × p < sub > 2 </ sub >) that this is a B.

Therefore, by using H < sub > 3 </ sub >< sup >+</ sup > as a probe of these clouds, their relative sizes can be determined.

Therefore, four loose families of more-efficient light transport modelling techniques have emerged: rasterization, including scanline rendering, geometrically projects objects in the scene to an image plane, without advanced optical effects ; ray casting considers the scene as observed from a specific point-of-view, calculating the observed image based only on geometry and very basic optical laws of reflection intensity, and perhaps using Monte Carlo techniques to reduce artifacts ; and ray tracing is similar to ray casting, but employs more advanced optical simulation, and usually uses Monte Carlo techniques to obtain more realistic results at a speed that is often orders of magnitude slower.

Therefore, in Euclidean geometry, any two lines that are both perpendicular to a third line are parallel to each other, because of the parallel postulate.

" Therefore any result in Euclidean geometry that follows from these three postulates will hold in elliptic geometry, such as proposition 1 from book I of the Elements, which states that given any line segment, an equilateral triangle can be constructed with the segment as its base.

Therefore, this case is what usually is meant when talking about Hilbert's sixteenth problem in real algebraic geometry.

Therefore, to produce the image which the retina beholds, using projective geometry techniques, it may be convenient to substitute a spherical surface of projection for a plane of projection, i. e., use a " picture sphere " rather than a " picture plane " and place the eye, or " station point ," at the center of the picture sphere.

Therefore distance geometry has immediate relevance where distance values are determined or considered, such as in surveying, cartography and physics.

Therefore, the central atom is predicted to adopt a linear geometry.

Therefore, the predicted geometry is trigonal.

Therefore the multistatic ambiguity function is mostly usefully defined as a function of two-or three-dimensional position and velocity vectors for a given multistatic geometry and transmitted waveform.

Therefore, since geometry is important in screen applications, screen materials should be at least specified by their gain and their total reflectance.

Therefore this is also the geometry of a C < sup > 2 </ sup >/ Z < sub > n </ sub > orbifold in string theory after its conical singularity has been smoothed away by its " blow up " ( i. e., deformation ).

Therefore, the Vice served as a central component to discrediting the Catholic Church in post-Reformation morality plays.

Therefore, safety plays are an important part of declarer technique at quantitative scoring.

Therefore, although safety plays have a certain role at matchpoints, they are normally avoided if the odds for making the contract are good and overtricks are likely.

Therefore, most Hasidic Jews, for whom Kabbalah plays an important role in their religious practice, traditionally do not remove or even trim their beards.

Therefore, Shakespeare must rewrite the plays and help the actors re-learn their lines.

Therefore they can be more accurately called the " English history plays ," a less common designation.

Therefore, many novels, movies, plays, and television programs employ roommates as a basic principle or a plot device.

Therefore Opportunity cost plays a major role in society.

Therefore the olfactory bulb plays this role for the olfactory system.

Therefore, it could stand by and allow a human to be hurt, as long as it plays no active part in it.

Therefore, human mutual grooming plays an important role in pair bonding.

Therefore, in their attempts to influence the impressions others form of themselves, a person plays an important role in affecting his social outcomes.

Therefore in the first round of the cup each professional team plays an amateur team.

Therefore, each player is invunerable until he / she possesses a host, after which the game plays as a normal deathmatch.

Therefore the solubilization plays a minor role in detergency.

Therefore, the playhouses had little choice but to present old plays and pantomime and plays that had no conceivable political content.

Therefore, Hijikata plays the ' bad guy ' to maintain order, and it is a role he plays well.

Therefore, the Jinsha River in the study of bronze culture plays an important role.

Therefore, a student ’ s emotion plays a big role during the learning process.
