Dominant long period

Table 2.1 Chemical and physical structures of the PUs studied in this work. Q is the relative SAXS scattering invariant obtained from the intensity distribution, d is the dominant long period obtained from q the position of the peak SAXS intensity, AJV is the particle surface-to-volume ratio obtained from SAXS, and y is the degree of crystallinity as determined from WAXS [135],...

From this, it can be seen that the optimum choice of 3D technique depends on the observing strategy appropriate to the particular scientific investigation. However there are other, second-order, considerations to be considered which violate this datacube theorem. These include whether the individual exposures are dominated by photon noise from the background or the detector, and the stability of the instrument and background over a long period of stepped exposures. [Pg.173]

Butin between lies the history of modern sculpture in the 20th century, which for long periods was molded by Western influences. In the first wave of modern sculpture that appeared shortly before and shortly after World War I, both in the West in the Bauhaus school, the futurists and the De Stijl group, and in the East among the Russian constructivists, a certain constructive dominance was certainly unmistakable. But in the 1930s, the traditions of East... [Pg.33]

Teleologically one could argue that the virion would pick up a fatty acid in its VP1 pocket before its egress from the cell, which would then stabilize the virion in transit to new hosts. The HR Vs are known to be stable for long periods of time on surfaces and the dominant mode of transmission is thought to be hand-to-hand contact [75,76]. When a new host cell is reached, the stabilization factor might exit the pocket. This would allow the necessary conformational transition (probably at the GH loop) to occur and allow productive uncoating. [Pg.500]

For small distances DLVO theory predicts that the van der Waals attraction always dominates. Please remember the van der Waals force between identical media is always attractive irrespective of the medium in the gap. Thus thermodynamically, or after long periods of time, we expect all dispersions to precipitate. Once in contact, particles should not separate again, unless they are strongly hit by a third object and gain a lot of energy. [Pg.103]

There is good evidence that hypercalcemia continued over a long period can cause severe and often permanent damage, especially cerebral, skeletal, and renal. In the later stages of severe cases an irreversible azotemia, possibly with hypertension and with secondary renal dwarfism, may dominate the clinical picture. Thus prognosis is materially influenced by early diagnosis and the early institution of adequate treatment. [Pg.172]

In the early generations after a pulse of new mutation, the impact is large, but very rapidly diminishes as the most harmful mutants are eliminated. Then there is a very long period when mutants with mild effects or recessive inheritance continue to exert their influence after the severe dominant mutants have been eliminated. If the environment improves, the average impact of the mutant genes diminishes. There will be an imperfect but positive correlation between the diminution in social impact of a mutant gene and its effect on fitness. The total hatched area of the lower graph is somewhat less if the curves were extended indefinitely, the areas would be approximately equal. However, in the future the environment may not continue to improve, but may fluctuate between improvement and decay. [Pg.172]

An important exception to the general trend in the xenolith data are exceptionally high He/" He ratios that have been observed in samples that have very low helium concentrations and have been exposed for long periods of time at the surface. Exposure to cosmic rays can result in the production of cosmogenic He (Craig and Poreda, 1986 Kurz, 1986), and this can dominate over the mantle He contained in the samples (Porcelli et al, 1987). Subsequent studies have endeavored to avoid any samples that may be susceptible to such alterations. [Pg.1009]

There are two main models that attempt to explain the success of the dinosaurs. According to one, dinosaurs out-competed the mammal-like reptiles over a long period of time due to superior adaptations such as upright walking. The other model, which is supported by fossil evidence, says that the dinosaurs took advantage of openings created by two mass extinctions. By the end of the Triassic, dinosaurs had taken over the land. They were dominant for 165 million years, from the Late Triassic until their extinction at the Cretaceous-Tertiary (K-T) boundary some 65 million years ago. This massive extinction may have taken place in only a week or lasted for tens of thousands of years this has not been determined yet, but further study may provide an answer. One prominent theory for the cause of this... [Pg.736]

Conspicuously, different from all other polymers is the antifreeze, which at all freezing rates partitioned equally between ice and the imfrozen solution i.e., it appears to be equally "soluble" in ice and water. This result confirms that the molecule can interact with the ice phase over a kinetically long period of time. It is not known from these results whether the mechanism is a permanent adsorption this would require supporting evidence from other physical measurement techniques. All the other solutes show a rate-dependent mechanism of partitioning, presumably dominated by the diffusion rates of the molecules. LEG and FVA may exhibit some nonkinetic partitioning properties, but this has not been conclusively proven. [Pg.682]
