Easily the best known of these three novels is The Space Merchants, a good example of a science-fiction dystopia which extrapolates much more than the impact of science on human life, though its most important warning is in this area, namely as to the use to which discoveries in the behavioral sciences may be put.

For example, " aloin " is derived from Aloe vera and Aloe ferox and has important medical uses ( e. g. as a laxative and in the treatment of burns ) as well as cosmetic uses ( e. g. in skin and hair products ).

Some of the species of Allium are important food plants for example onions ( Allium cepa ), chives ( A. schoenoprasum ), garlic ( A. sativum and A. scordoprasum ), and leeks ( A. porrum ).

For an example of its use, analysis of the concentration of elements is important in managing a nuclear reactor, so nuclear scientists will analyze neutron activation to develop discrete measurements within vast samples.

However, many important and interesting operations are non-associative ; one common example would be the vector cross product.

Another important example is the Tawagalawa Letter written by an unnamed Hittite king ( most probably Hattusili III ) of the empire period ( 14th-13th century BC ) to the king of Ahhiyawa, treating him as an equal and suggesting that Miletus ( Millawanda ) was under his control.

Another example is that body symmetry is an important aspect of physical attractiveness which may be due to this indicating good health during body growth.

This accompanied or facilitated other important evolutionary developments: the bilaterian body plan ; the coelom, an internal cavity that provided space for a circulatory system and, in some animals, formed a hydrostatic skeleton which enables worm-like animals to burrow ; metamerism, in which the body was built of repeated " modules " which could later specialize, for example the heads of most arthropods are composed of fused, specialized segments.

An important facet of The Settlers of Catan, for example, is convincing people to trade with you rather than with other players.

Politically, tourism is the more important of the two, as it employs a greater number of people within the Territory, and a larger proportion of the businesses in the tourist industry are locally owned, as are a number of the highly tourism-dependent sole traders ( for example, taxi drivers and street vendors ).

Glucose, one of the most important carbohydrates, is an example of a monosaccharide.

Eventually the head or " monarchic " bishop came to rule more clearly, and all local churches would eventually follow the example of the other churches and structure themselves after the model of the others with the one bishop in clearer charge, though the role of the body of priests remained important.

Botanists also study how plants produce food we can eat and how to increase yields and therefore their work is important in mankind's ability to feed the world and provide food security for future generations, for example, through plant breeding.

) Base stacking effects are especially important in the secondary structure and tertiary structure of RNA ; for example, RNA stem-loop structures are stabilized by base stacking in the loop region.

For example, drought and excessively salty soil are two important limiting factors in crop productivity.

Self-adjoint operators, where A = A < sup >†</ sup >, play an important role in quantum mechanics ; for example, an observable is always described by a self-adjoint operator.

An important example of such an algebra is a commutative C *- algebra.

As an example, in British Columbia the forestry industry is of great importance, while the oil and gas industry is important in Alberta, Saskatchewan and Newfoundland and Labrador.

To consider but one example, the First Amendment to the United States Constitution states " Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof "— but interpretation ( that is, determining the fine boundaries, and resolving the tension between the " establishment " and " free exercise " clauses ) of each of the important terms was delegated by Article III of the Constitution to the judicial branch, so that the current legal boundaries of the Constitutional text can only be determined by consulting the common law.

Condensed matter physics also has important applications to Biophysics, for example, the experimental technique of magnetic resonance imaging, which is widely used in medical diagnosis.

The per capita income of the CAR is often listed as being around $ 300 a year, said to be one of the lowest in the world, but this figure is based mostly on reported sales of exports and largely ignores the more important but unregistered sale of foods, locally-produced alcohol, diamonds, ivory, bushmeat, and traditional medicines, for example.

For example, he or she cannot veto the legislative budget, and thus Congress is sovereign over the year's single most important piece of legislation.

These shales are an important source rock for oil and gas, for example in the subsurface of the North Sea.

Another example is the place of The Wizard of Oz ( 1939 ) in American and British gay culture, although a widely viewed and historically important film in greater American culture.

for example, the mode of bravery to this anonymous folk poem: `` They brought me news that Spring is in the plains And Ahmad's blood the crimson tulip stains ; ;

For example the standard glutamic acid ( glutamate ) and the non-standard gamma-amino acid gamma-amino-butyric acid ( GABA ) are respectively the brain's main excitatory and inhibitory neurotransmitters, hydroxyproline-a major component of the connective tissue collagen-is synthesised from proline, the standard amino acid glycine is used to synthesise porphyrins used in red blood cells, and the non-standard carnitine is used in lipid transport.

For example, at the gene locus for the ABO blood type carbohydrate antigens in humans, classical genetics recognizes three alleles, I < sup > A </ sup >, I < sup > B </ sup >, and I < sup > O </ sup >, that determine compatibility of blood transfusions.

There are numerous qualitative chemical tests, for example, the acid test for gold and the Kastle-Meyer test for the presence of blood.

For example, the pelican, which was believed to tear open its breast to bring its young to life with its own blood, was a living representation of Jesus.

Certain kinds of organisms require particular additional elements, for example the magnesium in chlorophyll in green plants, the calcium in mollusc shells, or the iron in the hemoglobin in vertebrate animals ' red blood cells.

Compensation was based on the principle of substitution which might include material ( for example, cattle, slave ) compensation, exchange of brides or grooms, or payment of the blood debt.

Systems deriving from blood feuds may survive alongside more advanced legal systems or be given recognition by courts ( for example, trial by combat ).

For example, blood sugar is the monosaccharide glucose, table sugar is the disaccharide sucrose, and milk sugar is the disaccharide lactose ( see illustration ).

For example spermatozoa and avian red blood cells have more tightly packed chromatin than most eukaryotic cells and trypanosomatid protazoa do not condense their chromatin into visible chromosomes for mitosis.

For example, the abstract general idea or concept that is designated by the word " red " is that characteristic which is common to apples, cherries, and blood.

Isolation of T. cruzi can occur by inoculation into mice, by culture in specialized media ( for example, NNN, LIT ); and by xenodiagnosis, where uninfected Reduviidae bugs are fed on the patient's blood, and their gut contents examined for parasites.

For example, in the 1919 book Chemistry of Human Life physician George W. Carey states that, " Health depends on a proper amount of iron phosphate Fe < sub > 3 </ sub >( PO < sub > 4 </ sub >)< sub > 2 </ sub > in the blood, for the molecules of this salt have chemical affinity for oxygen and carry it to all parts of the organism.

For example, high glycine concentration disrupts temperature and blood pressure control, and high CSF pH causes dizziness and syncope .. To use Davson's term, the CSF has a " sink action " by which the various substances formed in the nervous tissue during its metabolic activity diffuse rapidly into the CSF and are thus removed into the bloodstream as CSF is absorbed.

For example, in the alveoli of mammalian lungs, due to differences in partial pressures across the alveolar-capillary membrane, oxygen diffuses into the blood and carbon dioxide diffuses out.

Injuries from losses of blood, for example, would not kill the bearer.

For example, a drug may influence a secondary clinical endpoint, such as a test result ( blood pressure, glucose or cholesterol levels ), without having the power to show that it decreases overall mortality or morbidity in a population.

The researcher can precisely determine, for example, the daily cycles of gene-activity, body temperature, blood pressure, hormone secretion and / or sleep and activity / alertness.

An example of this is Mondino de Liuzzi, who describes rudimentary blood circulation in his writings but still asserts that the left ventricle should contain air.

For example, bone morphogenic proteins stimulate bone cell differentiation, while fibroblast growth factors and vascular endothelial growth factors stimulate blood vessel differentiation ( angiogenesis ).

For example, when the blood glucose is low, hormones which raise the glucose should be rising and insulin secretion should be completely suppressed.

For example it is typically tested before or after blood donation.

Thus, they transduce information from the ECM to the cell as well as reveal the status of the cell to the outside, allowing rapid and flexible responses to changes in the environment, for example to allow blood coagulation by platelets.
