It seems to me that the first human being to reach one of these planets may well learn what it is to be a truly great and noble species ''.

For a chemical process the first of these might involve the concentrations of the different chemical species, and the temperature or pressure of the stream.

Lacking these membranes, amphibians require water bodies for reproduction, although some species have developed various strategies for protecting or bypassing the vulnerable aquatic larval stage.

Typhlonectes compressicauda, a species from South America, is typical of these.

Of these, 1, 356 ( 33. 6 %) were considered to be threatened and this figure is likely to be an underestimate because it excludes 1, 427 species for which there was insufficient data to assess their status.

There are four to ten of these holes, depending on the species.

For instance, antibacterial resistance genes can be exchanged between different bacterial strains or species via plasmids that carry these resistance genes.

Qualitative analysis gives an indication of the identity of the chemical species in the sample and quantitative analysis determines the amount of one or more of these components.

In general, antioxidant systems either prevent these reactive species from being formed, or remove them before they can damage vital components of the cell.

This effect is partly offset by the involvement of carotenoids in photoinhibition, and in algae and cyanobacteria, by large amount of iodide and selenium, which involves these antioxidants reacting with over-reduced forms of the photosynthetic reaction centres to prevent the production of reactive oxygen species.

One of these was the property, an essential universal true of the species, but not in the definition ( in modern terms, some examples would be grammatical language, a property of man, or a spectral pattern characteristic of an element, both of which are defined in other ways ).

It has not been definitively established whether the existence of these brainless species indicates that the earliest bilaterians lacked a brain, or whether their ancestors evolved in a way that led to the disappearance of a previously existing brain structure.

They overlap in range with 3 other crane species but interactions with these species and other " large wader " type birds are not known.

This is because these species tend to range in tropical habitats, although a few species do inhabit temperate and subarctic habitats.

After five to six weeks these are weaned and become fully mature near the end of their first year or sometime in their second year, depending on the species.

They are omnivorous, mostly eating fruit and insects, although the proportions of these foods vary greatly between species.

But there is a difference between these two species of colonies, with respect to the laws by which they are bound.

This is, a. o., particularly important for solubility studies of readily hydrolysed species such as Al, Eu, Am, Cm, ... or organic matter complexing these species.

Accumulation of toxins in fish threatens the survival of fish species, and human consumption of these fish can lead to health problems.

There are some remaining patches of dry forest high on steep mountainside including a number of endemic plant species, but these are inaccessible and hard to study.

Social capital is defined by Robert D. Putnam as " the collective value of all social networks and species ( who people know ) and the inclinations that arise from these works to do things for each other ( norms of reciprocity ).

There is no evidence of mass extinction of these organisms, and there is support for high productivity of these species in southern high latitudes as a result of cooling temperatures in the early Paleocene.

She said, `` My name is Songau and these girls are Ponkob and Piwen.

This is puzzling to an outsider conscious of the classic tradition of liberalism, because it is clear that these Democrats who are left-of-center are at opposite poles from the liberal Jefferson, who held that the best government was the least government.

And the great majority of these people are of Anglo-Saxon or Celtic descent.

A national consensus of near unanimity exists that these governmental efforts are desirable as well as necessary.

I have just asked these questions in the Pentagon, in the White House, in offices of key scientists across the country and aboard the submarines that prowl for months underwater, with neat rows of green launch tubes which contain Polaris missiles and which are affectionately known as `` Sherwood Forest ''.

Only one rule prevailed in my conversations with these men: The more highly placed they are -- that is, the more they know -- the more concerned they have become.

For these centers, too, are on the gold circuit.

What these fragments are and how they activate the go order may not be revealed.

Often, too, the social institutions are housed in these pavilions and palaces and bridges, for these great structures are not simply `` historical monuments '' ; ;

But more important, and the thing which the casual traveler and the blind sojourner often do not see, is that these places and activities are often the settings in which Persians exercise their extraordinary aesthetic sensibilities.

Water, air, fruit, poetry, music, the human form -- these things are important to Persians, and they experience them with an intense and discriminating awareness.

The line of an eyebrow, the color of the skin, a ghazal from Hafiz, the purity of spring water, the long afternoon among the boughs which crowd the upper story of a pavilion -- these things are noticed, judged, and valued.

Where are the writers to treat these changes??

Lucretius has remarked: `` The reason why all Mortals are so gripped by fear is that they see all sorts of things happening in the earth and sky with no discernable cause, and these they attribute to the will of God ''.

We have staved off a war and, since our behavior has involved all these elements, we can only keep adding to our ritual without daring to abandon any part of it, since we have not the slightest notion which parts are effective.

And Zen Buddhism, though it is extremely difficult to understand how these internal contradictions are reconciled, helps them in their struggle to achieve personal salvation through sexual release.

Whatever pole of this contrast one emphasizes and whatever the tension between these two approaches to understanding the artistic imagination, it will be readily seen that they are not mutually exclusive, that they belong together.

Underlying these conceptions of mimesis are certain presuppositions concerning the nature of primary human experience which require some exposition before the main argument can proceed.

Later abstractive and rational processes may indicate errors of judgment in these apprehensions of value, but the apprehensions themselves are the primary stuff of experience.

Of these there are surely few that would be more rewarding discoveries than Verner Von Heidenstam, the Swedish poet and novelist who received the award in 1916 and whose centennial was celebrated two years ago.

Somewhat uneven in interest for an average reader, eight or ten of these are among the finest of their kind in literature.
