Unfortunately the Nepōhualtzintzin and its teaching were among the victims of the conquering destruction, when a diabolic origin was attributed to them after observing the tremendous properties of representation, precision and speed of calculations.

Unfortunately, both properties are difficult to measure objectively, and only perceptual evaluations can be performed.

Unfortunately, many semiconductors with better electrical properties than silicon, such as gallium arsenide, do not form good semiconductor-to-insulator interfaces, thus are not suitable for MOSFETs.

Unfortunately, in the case of analog systems, none of these properties are ever perfectly achieved.

Unfortunately, the properties of bars in lenticular galaxies have not been researched in great detail.

Unfortunately, he did not observe its acid properties which led Chevreul to discover in 1820 stearic acid.

Unfortunately, they guess the structure of the Zones ( though not the actual properties ) backwards, coming to the conclusion that the bright center of the galaxy is the most likely location for advanced civilization.

Unfortunately, these two properties are not linearly proportional to the area of the contact.

Unfortunately, these properties have an inverse relationship.

Unfortunately, few of the artists ( writers, movie producers, dramatists and musicians ) who have used American folklore since 1900 have known enough to distinguish between the two streams even in the most general of ways.

Unfortunately, most operators are not commutative.

Unfortunately, some of the most commonly occurring disorders, such as heart disease, high blood pressure, Alzheimer's disease, arthritis, and diabetes, are caused by the combined effects of variations in many genes.

Unfortunately, most of the work was lost in a fire prior to publication.

Unfortunately, most lubricant that ends up directly in the environment is due to general public discharging it onto the ground, into drains and directly into landfills as trash.

Unfortunately the worldwide Great Depression of the time, triggered by the Wall Street Crash of 1929, meant that most of the plans remained on the drawing board.

Unfortunately, however, with the advent of artificial island development, most of their habitat is destroyed, or occupied by man-made structures.

Unfortunately, ambitious and uncalculated construction schemes, political unrest and an ever present international conflict, and presence of the most lucrative world supply of oil, along with lack of cooperation between Arab states and Iran, has had a negative impact on the survival of many marine species, including dugongs.

Unfortunately, most long-distance communication channels cannot transport a DC component.

Unfortunately, the pressure also subtly degrades the image in the plate, smoothing the roughened areas and closing the lines ; a copper plate is good for, at most, a few hundred printings of a strongly etched imaged before the degradation is considered too great by the artist.

Unfortunately, the once-promising plan was for the most part a disappointment.

Unfortunately, high excursion, at high power levels, tends to produce more distortion from inherent mechanical and magnetic effects in electro-dynamic drivers ( the most common sort ).

Unfortunately programs could not switch directly between them, so eventually, some new memory-model APIs were developed, VCPI and DPMI, the latter becoming the most popular.

Unfortunately, most of the writings of the Báb have been lost.

Unfortunately, many patients, not realizing the need for dental treatment, do not see a dentist until most of their teeth are beyond the point of restoration.

Unfortunately, the fact that a character was stored in a byte led to the two terms being used interchangeably in most documentation.

Unfortunately, most of his officers and soldiers were tired of the delaying tactics and demanded another attempt at an open battle.

Early administration of anthelmintics, such as mebendazole or albendazole, decreases the likelihood of larval encystation, particularly if given within three days of infection Unfortunately, most cases are diagnosed after this time.

Unfortunately, he has never learned how to make hooks with a barb, and so most of his fish escape.

Unfortunately all marks, for the most part were gone and he had to lay the whole town markings out again.

Unfortunately, in the early morning hours of November 3, 1908, a fire swept throughout Savannah and destroyed most of the village.

Unfortunately, since it is indeed a small town with limited infrastructure, the city has lost most of its business to Walla Walla, Washington just to the north.

Unfortunately, years later a fire burned most of this building down.

Unfortunately, Groom's vision of the finest and most desirable cattle ranch in the United States did not materialize for him.

Unfortunately, this has become the only Japanese language version for which 35mm materials are available to Toho, and it is unclear what happened to the uncut original version's 35mm elements.

Unfortunately this design has proven difficult to build due to a lack of proper materials, namely high-temperature non-magnetic materials that are also able to withstand the chemically active exhaust.

Unfortunately, it is not useful for all systems: In strongly correlated materials, the elementary excitations are so far from being independent that it is not even useful as a starting point to treat them as independent.

Unfortunately the valves that should have been used to divert the drainage outfall to a hazardous materials sump were rusted stuck and the gasoline went into a nearby lake.

Unfortunately an Earth-to-orbit rotovator cannot be built from currently available materials since the thickness and tether mass to handle the loads on the rotovator would be uneconomically large.

Unfortunately, his choice of materials was a poor one-the not-so-revolutionary Sateen Dura-Luxe and tape eventually fell off, essentially destroying all of his work over time.

Unfortunately, there are no solid materials with such a low refractive index.

Unfortunately, the settling of these materials and the pressure of urban development has led to an unstable shoreline and reduced water quality.

Unfortunately, the organic materials used were also very susceptible to the two most significant impediments to preservation and conservation: the elements, and life ( both human and animal ).

Unfortunately there are no primary source materials that have been uncovered that confirm Bugbee ’ s involvement in the design process.

Unfortunately, the two simultaneous shipments were misdirected, the materials for his residence heading towards Egypt, and the Alexandria train station ending up in Dalaman.
