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 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 thermometers have now been sent to the United Kingdom for calibration at the National Physical Laboratory.

These provisions are designed to reflect the differences in wealth and population among the States, with the objective that a vocationally handicapped person have access to needed services regardless of whether he resides in a State with a low or high per capita income or a sparsely or thickly populated State.

These could be costly and have a serious effect both at home and abroad.

These destructive forces also have a seriously adverse effect upon the watersheds and their life-supporting waterflows, and upon the other renewable forest resources.

These specialists, I learned, have done a great deal of work to improve the size and health of the plants and the resulting flowers.

These engines have a cylinder diameter of 3-7/8 inches and a stroke length of 3 inches.

`` These recent steps do not offer the possibility of extension to the great number of senior engineers who have displayed technical competence.

These have to do with property rights, municipal official attitudes and a host of others.

These vehicles, with large sensitive areas, have collected data for long enough times to give reliable impact rates for the periods of exposure.

These dosages could have been increased by increasing the source strength which was small in this case.

These have been labeled Regions 1, 2, and 4, respectively, in Fig. 1.

These drugs have no effect on the iodide concentrating mechanism, but they inhibit organification.

These groups have varied widely from mere families, primitive, totemic groups, and small modern cults and sects, to the memberships of great denominations, and great, widely dispersed world religions.

These things have been disseminated by other means, but always in the wake of extensive publication of analytic results.
