These studies are being extended to different polymers to increase our knowledge about the hindrances to rotation around chain bonds.

These bonds, which are stronger than the sp < sup > 3 </ sub > bonds found in alkanes and diamond, provide nanotubes with their unique strength.

These asymmetric bonds mean a strand of DNA has a direction.

These fatty acids contain double bonds within carbon chain.

These extracellular loops also contain two highly-conserved cysteine residues that form disulfide bonds to stabilize the receptor structure.

These bonds can extend well into adulthood.

These two polymorphs differ by a " kinking " of bonds ; this change in structure gives β-quartz greater symmetry than α-quartz, and they are thus also called high quartz ( β ) and low quartz ( α ).

These forms are called furanoses and pyranoses, respectively — by analogy with furan and pyran, the simplest compounds with the same carbon-oxygen ring ( although they lack the double bonds of these two molecules ).

These digestive juices break chemical bonds in ingested molecules, and modify their conformations and energy states.

These sub-units are typically connected by covalent chemical bonds.

These strong hydrogen bonds, for example, result in the high tensile strength and melting point of polymers containing urethane or urea linkages.

These properties derive from ultraviolet's power to alter chemical bonds, even without having quite enough energy to ionize atoms.

These properties derive from the ultraviolet photon's power to alter chemical bonds in molecules, even without having enough energy to ionize atoms.

These C-H bonds are adjacent to carbon-carbon double bonds.

These findings challenge previous beliefs that exposure to diversity strengthens social capital, either through bridging social gaps between ethnicities or strengthening in-group bonds.

These bonds have a higher risk of default or other adverse credit events, but typically pay higher yields than better quality bonds in order to make them attractive to investors.

These bonds are called " fallen angels ".

These bonds are maintained year round, even in gregarious and migratory species like the Tundra Swan, which congregate in large flocks in the wintering grounds.

These pair bonds take several years to develop in some species, particularly with the albatrosses.

These bank notes were not to be backed by just government bonds, but also just about any securities the banks were holding.

These are in general different in a number of ways from the bonds discussed in this article.

These simply did not exist.

These organizations exist to " support the conservation professionals who preserve our cultural heritage ".

These damages need not be set forth in statute as they already exist in the tradition of common law.

These are usually ' temps ' ( temporary workers ) or consultants who, depending on the project and their experience, might be brought on to lead a task for which the skill-set did not exist within the company, or in the case of a temp, in the vernacular sense, to perform busy-work or an otherwise low-skilled repetitive task for which an employee is deemed too valuable to perform.

These are all proper inclusions, meaning that there exist recursively enumerable languages which are not context-sensitive, context-sensitive languages which are not context-free and context-free languages which are not regular.

These terms by themselves are not very precise, and many subtle intermediate cases exist.

These are typically of the form " N exists " or " Ss exist ".

These organizations exist on local, national, and international scales.

These books, with their lurid titles, were once thought to be the creations of Jane Austen's imagination, though later research by Michael Sadleir and Montague Summers confirmed that they did actually exist and stimulated renewed interest in the Gothic.

These proteins are homologous to the alpha ( α ) subunit found in heterotrimers, but exist as monomers.

These rights may exist as natural rights or as legal rights, in both national and international law.

These are general rules of interpretation ; specific rules might exist in specific areas of international law.

These are not identical, but one must exist in order to progress toward a goal.

These odd sanctuaries have proven so popular and lucrative for ecotourism that efforts exist to prevent removal of the mines.

These perfectly periodic orbits, referred to as " halo " orbits, do not exist in a full n-body dynamical system such as the Solar System.

These linguists argue that the concept of a Language Acquisition Device ( LAD ) is unsupported by evolutionary anthropology, which tends to show a gradual adaptation of the human brain and vocal cords to the use of language, rather than a sudden appearance of a complete set of binary parameters delineating the whole spectrum of possible grammars ever to have existed and ever to exist.

These nations often exist only on paper, on the Internet, or in the minds of their creators.

These exist as a < sup > 3 +</ sup > complexes:

These receptors, which exist in a variety of areas in the body, inhibit firing of neurons that would otherwise be stimulated to do so by nociceptors.

These guide RNAs belong to the class of small nucleolar RNAs ( snoRNAs ) which are complexed with proteins and exist as small-nucleolar-ribonucleoproteins ( snoRNPs ).

These polynomials can be added by simply adding corresponding coefficients ( the rule for extending by terms with zero coefficients can be used to make sure such coefficients exist ).

These demands are contradictory and impossible to realize ( massless arms and zero-friction bearings do not exist in the real world ), so tone arm designs require engineering compromises.

These programs currently exist in Arizona, Florida, Illinois, Iowa, Minnesota, Pennsylvania and Rhode Island in the United States.

These two variants do not exist in any other manuscript, and it seems they were made by a scribe.
