Rather than putting their trust in ephemeral sensations they seek form in the stable relationships of pure design, which symbolize an order more real than the disorder of the perceptual world.

And irrespective of the outcome in centuries elapsed since splitting, calculations obviously carry more concordant and comparable meaning if they deal with the most stable units than with variously unstable ones.

but very few seemed aware that such acceptance and identification need to be supplemented with more enduring and stable identification of and with one's self.

Due to the averaging it is far more stable than any clock would be alone ( see signal averaging for a discussion ).

In 1875 Nobel invented gelignite, more stable and powerful than dynamite, and in 1887 patented ballistite, a forerunner of cordite.

Gelignite was more stable, transportable and conveniently formed to fit into bored holes, like those used in drilling and mining, than the previously used compounds and was adopted as the standard technology for mining in the Age of Engineering bringing Nobel a great amount of financial success, though at a significant cost to his health.

Above this temperature and in ambient light, this metastable allotrope transforms into the more stable black allotrope.

A more numerically stable two-pass algorithm first computes the sample means, and then the covariance:

For substances which have two ( or more ) stable crystalline forms, such as diamond and graphite for carbon, there is a kind of " chemical degeneracy ".

Perfect crystals never occur in practice ; imperfections, and even entire amorphous materials, simply get " frozen in " at low temperatures, so transitions to more stable states do not occur.

Current hypotheses suggest that asexual reproduction may have short term benefits when rapid population growth is important or in stable environments, while sexual reproduction offers a net advantage by allowing more rapid generation of genetic diversity, allowing adaptation to changing environments.

Alkenes are relatively stable compounds, but are more reactive than alkanes due to the presence of a carbon-carbon pi-bond.

Although the permanency of acrylics is sometimes debated by conservators, they appear more stable than oil paints.

He particularly criticized the Indo-European languages for promoting a mistaken essentialist world view, which had been disproved by advances in the sciences, whereas he suggested that other languages dedicated more attention to processes and dynamics rather than stable essences.

As to the α and β phases, they might both coexist at ambient conditions with the β phase being more stable.

DNA with high GC-content is more stable than DNA with low GC-content, but, contrary to popular belief, the hydrogen bonds do not stabilize the DNA significantly, and stabilization is mainly due to stacking interactions.

They were partly correct: a white dwarf slightly more massive than the Chandrasekhar limit will collapse into a neutron star, which is itself stable because of the Pauli exclusion principle.

Thus, at a given angular rate of rotation, a concave surface represents the stable situation, and the more rapid the rotation, the more concave this surface.

Bistability as applied in the design of mechanical systems is more commonly said to be " over centre " -- that is, work is done on the system to move it just past the peak, at which point the mechanism goes " over centre " to its secondary stable position.

Only in the 18th century did a steady economic and demographic growth begin, an effect of the reforms by Spain's Bourbon dynasty and a more stable situation along the frontier.

Most ( 66 of 94 ) naturally occurring elements have more than one stable isotope.

For example, the reference state for carbon is graphite, because it is more stable than the other allotropes.

Beginning with carbon, elements are produced in stars by buildup from alpha particles ( helium nuclei ), resulting in an alternatingly-larger abundance of elements with even atomic numbers ( these are also more stable ).

Second, and even more importantly, working memory allows information to be integrated over time so that it can generate a stable representation of the world — Gerald Edelman expressed this point vividly by titling one of his books about consciousness The Remembered Present.

By observing which areas of the brain take up the radioactive isotope, we can see which areas of the brain are more active than other areas.

Whenever a relative atomic mass value differs by more than 1 % from a whole number, it is due to this averaging effect resulting from significant amounts of more than one isotope being naturally present in the sample of the element in question.

The isotope of einsteinium with the longest half life, einsteinium-252 ( half life 471. 7 days ) would be more suitable for investigation of physical properties, but it has proven far more difficult to produce and is available only in minute quantities, and not in bulk.

This isotope of radioactive iodine used for ablative treatment is more potent than diagnostic radioiodine ( usually iodine-123 or a very low amount of iodine-131 ), which has a biological half life from 8 – 13 hours.

The most abundant isotope, hydrogen-1, protium, or light hydrogen, contains no neutrons ; other isotopes of hydrogen, such as deuterium, contain one or more neutrons.

Indium also has 47 meta states, out of which indium-114m1 is the most stable, being more stable than ground state of any indium isotope, except for the primordial ones.

In this case, the bismuth would present some minor radiation problems, as it is not quite as transparent to neutrons, and can be transmuted to a radioactive isotope more readily than lead.

Further development in physical chemistry may be attributed to discoveries in nuclear chemistry, especially in isotope separation ( before and during World War II ), more recent discoveries in astrochemistry, as well as the development of calculation algorithms in field of " additive physicochemical properties " ( practically all of physicochemical properties, as: boiling point, critical point, surface tension, vapor pressure etc.

Rubidium has only one stable isotope, < sup > 85 </ sup > Rb, with the isotope < sup > 87 </ sup > Rb, which composes almost 28 % of naturally occurring rubidium, being slightly radioactive with a half-life of 49 billion years — more than three times longer than the estimated age of the universe.

Upon bombardment with slow neutrons, its uranium-235 isotope will most of the time divide into two smaller nuclei, releasing nuclear binding energy and more neutrons.

However, it is a major concern to those in the field of nuclear proliferation because it may be cheaper and more easily hidden than other methods of isotope separation.

As a result the isotope may emit alpha, beta, or gamma radiation in order to become more stable.

It also contains the undesirable isotope uranium-236 which undergoes neutron capture, wasting neutrons ( and requiring higher U-235 enrichment ) and creating neptunium-237 which would be one of the more mobile and troublesome radionuclides in deep geological repository disposal of nuclear waste.

Of the 80 elements with one or more stable isotopes, twenty-six have only a single stable isotope, and are thus termed monoisotopic, and the rest have more than one stable isotope.

These isotope systems for lighter elements that exhibit more than one primordial isotope for each element, have been under investigation for many years in order to study processes of isotope fractionation in natural systems.

Ẓahīr ad-Dīn Muḥammad (, also known by his royal titles as al-ṣultānu ' l-ʿazam wa ' l-ḫāqān al-mukkarram bādshāh-e ġāzī ), is more commonly known by his nickname, Bābur (< big > بابر </ big >).

The foliate density can vary as a function of deposition conditions ( e. g. temperature and time ) with their structure ranging from few layers of graphene (< 10 ) to thicker, more graphite-like.

Calcium has four stable isotopes (< sup > 40 </ sup > Ca, < sup > 42 </ sup > Ca, < sup > 43 </ sup > Ca and < sup > 44 </ sup > Ca ), plus two more isotopes (< sup > 46 </ sup > Ca and < sup > 48 </ sup > Ca ) that have such long half-lives that for all practical purposes they also can be considered stable.

With 47 unknown cards, the player will make the straight approximately one time for every five times he doesn't, thus a bet is profitable if six or more of his opponents will call the bet ( he will win once (< font color =" green ">+ 6 bets </ font >) and lose five times (< font color =" red ">- 5 bets </ font >) out of every six hands like this, resulting in an expectation of < font color =" green ">+ 1 bet </ font >).

Although most free silicon is used in the steel refining, aluminum-casting, and fine chemical industries ( often to make fumed silica ), the relatively small portion of very highly purified silicon that is used in semiconductor electronics (< 10 %) is perhaps even more critical.

Note that the size of the columns depends loosely on the rate of cooling ; very rapid cooling may result in very small (< 1 cm diameter ) columns, while slow cooling is more likely to produce large columns.

For example, a quartz arenite would be composed of mostly (> 90 %) quartz grains and have little / no clayey matrix between the grains, a lithic wacke would have abundant lithic grains (< 90 % quartz, remainder would have more lithics than feldspar ) and abundant muddy matrix, etc.

Amalthea radiates slightly more heat than it receives from the Sun, which is probably due to the influence of Jovian heat flux (< 9 kelvins ), sunlight reflected from the planet (< 5 K ), and charged particle bombardment (< 2 K ).

The pawn (< font size = 4 face = Arial Unicode MS >♙♟</ font >) is the most numerous and ( in most circumstances ) weakest piece in the game of chess, historically representing infantry, or more particularly armed peasants or pikemen.

Buddhi is a feminine Sanskrit noun derived from the same root as the more familiar masculine form Buddha (< budh-to be awake, to understand, to know ).

Contra: these words are rare and it is therefore more probable that * zd was absorbed by * dz (< * dj, * gj, * j ); further, a change from the cluster / zd / to the affricate / dz / is typologically more likely than the other way around ( which would violate the sonority hierarchy ).

As a result, exudates are high in protein, high in lactate dehydrogenase, have a low pH (< 7. 30 ), a low glucose level, and more white blood cells.

In western New York, soras were significantly ( p = 0. 007 ) more abundant in marshes from 100 to 250 acres ( 41 – 100 ha ) in size than in smaller (< 100 acres ( 41 ha )) or larger ( 250 – 380 acres ( 101 – 155 ha )) marshes.

In the breeding season the males can be separated with difficulty (< 80 % accuracy in comparison to molecular methods ) based on the more even shade of the red underparts that extend towards the rear of the belly.

For example, western tanagers appear to occur more often in mature ( 50 – 60 years old ) and old-growth ( 100 + years ) quaking aspen than young (< 23 years old ) trembling aspen stands in the Prince Rupert Forest Region of British Columbia.

They point out that the Hebrew words for father (< nowiki >'</ nowiki > ab ) and son ( ben ) can also mean forefather and descendant, respectively, and that the Biblical scripture occasionally " telescopes " genealogies to emphasize the more important ancestors.

An alternate form of the letter El (< span style =" font-family: ' Garamond ', ' Gill Sans ', serif ; font-size: larger "> Л л </ span >; italics: < span style =" font-family: ' Garamond ', ' Gill Sans ', serif ; font-size: larger "> Л л </ span >), more closely resembles the Greek letter Lambda ( Λ λ ).

In this trial, " on the basis of serum procalcitonin concentrations, use of antibiotics was more or less discouraged (< 0. 1 mcg / L or < 0. 25 mcg / L ) or encouraged (> or

The heavier isotope (< sup > 18 </ sup > O ) condenses more readily as temperatures decrease and falls as precipitation, while the lighter isotope (< sup > 16 </ sup > O ) can fall in even colder conditions.
