Because boron is produced entirely by cosmic ray spallation and not by stellar nucleosynthesis, it is a low-abundance element in both the solar system and the Earth's crust.

Because it was extraordinarily expensive the Pascaline became little more than a toy, and status symbol, for the very rich both in France and throughout Europe.

Because ballpoint pens are low cost alternatives to both fountain pens and roller-ball pens, they have become largely a disposable product.

Because bipolar disorder can have a high rate of both under-diagnosis and misdiagnosis, it is often difficult for individuals with the condition to receive timely and competent treatment.

Because they are both hydrogen-bond acceptors ( the carbonyl ) and hydrogen-bond donors ( the hydroxyl ), they also participate in hydrogen bonding.

Because of the similar conditions, both reactions in the E1 or E1cb elimination always compete with the S < sub > N </ sub > 1 substitution.

Because some materials have both useful mineral content and recoverable calorific value, the distinction between alternative fuels and raw materials is not always clear.

Because of the stylistic similarities between comic strips and early animated movies, " cartoon " came to refer to animation, and the word " cartoon " is currently used to refer to both animated cartoons and gag cartoons.

Because mass actions operate outside the detailed procedures laid out for class actions, they can pose special difficulties for both plaintiffs, defendants, and the court.

Because no species other than Homo sapiens has survived from the human line of that branching, both chimpanzee species are the closest living relatives of humans.

Because these two phenomena's mechanics are mutually exclusive, both are needed in order to describe the possible behaviors.

Because deism asserts God without accepting claims of divine revelation, it appeals to people from both ends of the religious spectrum.

Because these paired books had to fit a fixed total page length, one or both were usually abridged to fit, and Wollheim often made other editorial alterations — as witness the differences between Poul Anderson's Ace novel War of the Wing-Men and its definitive revised edition, The Man Who Counts.

Because St. Louis was geographically isolated from both the dominating teams and the major sports media ( newspapers ) of the era ... all centered in and focused on the East ... Cochems ' groundbreaking offensive strategy was not picked up by the major teams.

Because of this necessity to have relations with other rational beings in order to achieve consciousness, Fichte writes that there must be a ' relation of right ,' in which there is a mutual recognition of rationality by both parties.

Because of its strategic location it is in both the Russian and American spheres of influence.

Because Formalin-fixed, paraffin-embedded ( FFPE ) tissues may be stored indefinitely at room temperature, and nucleic acids ( both DNA and RNA ) may be recovered from them decades after fixation, FFPE tissues are an important resource for historical studies in medicine.

Because of its long seacoast, Italy also has a large number of harbors for the transportation of both goods and passengers.

Because most such alleles are rare in populations, it is unlikely that two unrelated marriage partners will both be heterozygous carriers.

Because of this, a civil libertarian outlook is compatible with many other political philosophies, and civil libertarianism is found on both the right and left in modern politics.

Because such strains transfer chromosomal genes very efficiently they are called Hfr ( high frequency of recombination ).

Because this band is higher in frequency than bands currently in use by deep-space missions, the same amount of data can be sent by smaller equipment in space and on the ground.

* Because the device is never shut off completely there is no " turn on " time, little problem with charge storage, and generally better high frequency performance and feedback loop stability ( and usually fewer high-order harmonics ).

Because waves at different frequencies propagate at differing phase velocities in dispersive media, for a large frequency range ( a narrow envelope in space ) the observed pulse would change shape while traveling, making group velocity an unclear or useless quantity.

Because of this choice of frequency band, 802. 11b and g equipment may occasionally suffer interference from microwave ovens, cordless telephones and Bluetooth devices.

Because this makes the frequency of the released radio signal also dependent on its origin in a predictable manner, the distribution of protons in the body can be

Because planned actions can typically only be submitted at a fixed maximum frequency ( e. g., once every few days or every few weeks ), the number of discrete actions is limited compared to real-time games.

* Because bass sounds have a higher amplitude than high frequency sounds ( for the same perceived loudness ), the space taken in the groove by low frequency sounds needed to be large ( limiting playback time per side of the record ) to accommodate the bass notes, yet the high frequencies required only tiny variations in the groove, which were easily affected by noise from irregularities ( wear, contaminates, etc.

Because it uses frequency modulation, SECAM is not linear with respect to the input image ( this is also what protects it against signal distortion ), so electrically mixing two ( synchronized ) SECAM signals does not yield a valid SECAM signal, unlike with analog PAL or NTSC.

Because high frequency signals can flow to earth through capacitance, capacitance to ground is an important factor in effectiveness of signal grounds.

Because current in these systems is interrupted by a switching action, the current contains frequency components that are multiples of the power system frequency.

Because the spectrum from Planck's law of black body radiation takes a different shape in the frequency domain from that of the wavelength domain, the frequency location of the peak emission does not correspond to the peak wavelength using the simple relationship between frequency, wavelength, and the speed of light.

Because SQUIDs can operate at acquisition rates much higher than the highest temporal frequency of interest in the signals emitted by the brain ( kHz ), MEG achieves good temporal resolution.

Because of reversibility, the Fourier transform is called a representation of the function, in terms of frequency instead of time ; thus, it is a frequency domain representation.

Because it is easy to calculate, OPS has been used with increased frequency in recent years as a shorthand form to evaluate contributions as a batter.

Because of the geometric relationship, the Doppler shifted geometric chirp will effectively start at a different frequency ( multiplied by a constant ), but follow the same pattern of exponential frequency increase, so the end of the original wave, for instance, will still overlap perfectly with the beginning of the reflected wave, and the magnitude of the correlation will be high for that section of the wave.

Because the speaker is constantly moving either toward or away from the listener, however, the mechanism's rotation is constantly affecting the listener-perceived sound's wavelength by either " stretching " the wave ( increasing wavelength ) or " squeezing " it ( decreasing wavelength ) -- and because frequency, i. e., pitch, is inversely proportional to wavelength, such that increasing wavelength decreases frequency and vice versa, any listener for whom the speaker's motion changes the sound's perceived amplitude ( i. e., any listener whose distance from the speaker is changing ) must also perceive a change in frequency.
