However, he realized that his equations permitted the introduction of a constant term which could counteract the attractive force of gravity on the cosmic scale.

However, the efforts in integrated circuit development culminated in the introduction in early 1971 of the first " calculator on a chip ", the MK6010 by Mostek, followed by Texas Instruments later in the year.

However, the plantations, both under their previous private ownership and under government administration, proved consistently unprofitable due to the introduction of new oils and lubricants in the international marketplace, and the establishment of vast coconut plantations in the East Indies and the Philippines.

However, as mentioned in the introduction, biographical details such as these should be regarded with scepticism.

However, " his plays continued to be applauded even after those of Aeschylus and Sophocles had come to seem remote and irrelevant ", they became school classics in the Hellenistic period ( as mentioned in the introduction ) and, due to Seneca's adaptation of his work for Roman audiences, " it was Euripides, not Aeschylus or Sophocles, whose tragic muse presided over the rebirth of tragedy in Renaissance Europe.

However, the sulfur content of traditional gunpowders caused corrosion problems with Cordite Mk I and this led to the introduction of a range of sulfur-free gunpowders, of varying grain sizes.

However, during the revolution, the NTC has made the introduction of multiparty democracy a cornerstone of its agenda.

However, after the Revenge of the Nerds movie franchise ( with multicultural nerds ), and the introduction of the Steve Urkel character on the television series Family Matters, nerds have been seen in all races and colors as well as more recently being a frequent young Asian or Indian male stereotype in North America.

However, the ongoing efforts to standardize the X11 system led to its introduction and widespread use on Sun systems, and NeWS never became widely used.

However, the 1960 shootdown of a CIA U-2 by an SA-2 Guideline surface-to-air missile ( SAM ) while on a clandestine reconnaissance mission over the Soviet Union suddenly complicated the introduction of these new aircraft.

However, introduction of the H. influenza type B ( Hib ) vaccine has dramatically decreased H. influenza type B infections and now non-typable H. influenza ( NTHI ) are predominantly seen in clinics.

However, only in 1821, following the introduction of the gold sovereign coin by the new Royal Mint at Tower Hill in the year 1816, was the United Kingdom formally put on a gold specie standard, the first of the great industrial powers to do so.

However, there was a gradual introduction of enlightened reforms, and this process culminated at the end of the century when even non-Catholics were granted the right to study.

However, the technique is not simple to learn, at least before the introduction of " shaped skis " in the 1990s.

However, it was Grace Warrack's 1901 version of the book with its " sympathetic informed introduction " which introduced most early twentieth-century readers to Julian.

However, by the late 1950s with the introduction of finer-grained color stocks and the disadvantage of shooting twice as much negative stock, VistaVision became obsolete.

However, specialists of this period of Byzantine history, such as Paul Lemerle, have shown that Photius could not have compiled his Bibliotheca in Baghdad because he clearly states in both his introduction and his postscript that when he learned of his appointment to the embassy, he sent his brother a summary of books that he read previously, " since the time I learned how to understand and evaluate literature " i. e. since his youth.

However, with the gradual introduction of computer aided drafting and design ( CADD or CAD ) in the last decades of the 20th century and the first of the 21st century, the drawing board is becoming less common.

However, Schluter didn't just copy the Leedy design, he introduced several significant improvements: making the bars from aluminum instead of steel for a more " mellow " basic tone ; adjustments to the dimensions and tuning of the bars to eliminate the dissonant harmonics in the Leedy design ( further mellowing the tone ); and the introduction of a damper bar controlled by a foot pedal, enabling it to be played with more expression.

However in the introduction of his book he states:

However, MFS had been optimized to be used on very small and slow media, namely floppy disks, so HFS was introduced to overcome some of the performance problems that arrived with the introduction of larger media, notably hard drives.

However, his most significant translation was probably the Isagoge of Johannitius, which would serve as an introduction to medical theory and practice for centuries.

However, with introduction of font formats such as OpenType, those supplemental glyphs were merged into the main fonts, relying on specific software capabilities to access the alternate glyphs.

However, after the introduction of DC's multiverse in the 1960s, this version of Krypton was declared to be the Krypton of the Earth-Two universe ( the native dimension of DC's Golden Age characters ) and its Superman.

However, this has now been replaced by a more professional exhibition space incorporating laser, video, slide shows, audio commentaries, and some interactive elements.

However, phthalocyanine is more sensitive than cyanine to writing laser power calibration, meaning that the power level used by the writing laser has to be more accurately adjusted for the disc in order to get a good recording ; this may erode the benefits of dye stability, as marginally written discs ( with higher correctable error rates ) will lose data ( i. e. have uncorrectable errors ) after less dye degradation than well written discs ( with lower correctable error rates ).

However, more recent experiments have demonstrated that cells whose centrioles have been removed via laser ablation can still progress through the G < sub > 1 </ sub > stage of interphase before centrioles can be synthesized later in a de novo fashion.

However, sudden or accidental disruption of the laser will register unwanted keystrokes.

However even such a divergent beam can be transformed into a similarly collimated beam by means of a lens system, as is always included, for instance, in a laser pointer whose light originates from a laser diode.

However in the case of the free electron laser, atomic energy levels are not involved ; it appears that the operation of this rather exotic device can be explained without reference to quantum mechanics.

However, the popular description of light being " stopped " in these experiments refers only to light being stored in the excited states of atoms, then re-emitted at an arbitrary later time, as stimulated by a second laser pulse.

However, for printing technologies that perform color mixing through dithering rather than through overprinting ( virtually all home and office, inkjet and laser printers included ), printer DPI and image PPI have a very different meaning, and this can be misleading.

However, the laser was never more than one of the many systems being researched for ballistic missile defense.

However, the same term is used even in the laser oscillators, when amplified radiation is used to transfer energy rather than information.

However, if the laser brightness is reduced until only a handful of photons hit the wall every second, the relative fluctuations in number of photons, i. e., brightness, will be significant, just as when tossing a coin a few times.

However, some CD-ROM drives and players have problems reading these CDs, mostly because the groove spacing is outside specifications and the player's laser servo is unable to track it.

However, with the abundance of laser sources available today it is easy to perform a Arago spot experiment ( see for example here ).

However, not much should be read into this price difference as the printing costs for inkjet and laser printers are a great deal higher than for dot matrix printers, and the inkjet / laser printer manufacturers effectively use their monopoly over arbitrarily priced printer cartridges to subsidise the initial cost of the printer itself.

However, low-cost laser printers can have lower per-page costs, at least for black-and-white printing, and possibly for color.

However, this approach made a comeback following further innovations, and is being developed at both the United States National Ignition Facility, the French Laser Mégajoule as well as the planned European Union High Power laser Energy Research ( HiPER ) facility.

However, almost all modern computer printers also create their output as matrices of dots, but use a different technology like laser printing or inkjet printing, and are not called Dot Matrix printers.

However, modern instrumentation almost universally employs notch or edge filters for laser rejection and spectrographs ( either axial transmissive ( AT ), Czerny-Turner ( CT ) monochromator, or FT ( Fourier transform spectroscopy based ), and CCD detectors.

However, since most lasers are monochromatic, color filters can reduce the effect of laser pointers.

However, filters will also impair image quality and overall light sensitivity of cameras ( see laser safety article for details on issues with filters ).

However, laser mice did not enter the mainstream market until 2004, when Paul Machin at Logitech, in partnership with Agilent Technologies, introduced its MX 1000 laser mouse.
