Some introduced populations thrive and evolve despite the presumed loss of diversity at introduction. We aimed to quantify the amount of genetic diversity retained at introduction in species that have shown evidence of adaptation to their introduced environments. Samples were taken from native and introduced ranges of Arctotheca populifolia and Petrorhagia(More)
Oropharyngeal and esophageal pressures were measured via a tip-transducer during mono- and binasal CPAP in 30 neonates. During nasal CPAP, increasing flows are followed by an increase in oropharyngeal pressure, although there were great variations among the pressures recorded. On the other hand, no increase in the esophageal pressure could be registered(More)
Twenty-nine provenances of teak (Tectona grandis Linn. f.) representing the full natural distribution range of the species were genotyped with microsatellite DNA markers to analyse genetic diversity and population genetic structure. Provenances originating from the semi-moist east coast of India had the highest genetic diversity while provenances from Laos(More)
Z. Naturforsch. 51a, 5 6 0 5 6 4 (1996); received December 12, 1995 Time Differential Perturbed Angular Distribution (TDPAD) measurements of the nuclear quadrupole hyperfine parameters for 1 9 F* implanted into amorphous, polycrystalline and crystalline silicon and germanium are reported and reviewed. Two signals are observed in the crystalline materials ((More)
It has been an accepted fact for more than 40 years that the E center in Si (the group-V impurity--vacancy pair)--one of the most studied defects in semiconductors--has only one energy level in the band gap: namely, the acceptor level at about 0.45 eV below the conduction band. We now demonstrate that it has a second level, situated in the lower half of the(More)
Several recent studies indicate that there are major differences in the defect population between ion implanted and electron damaged silicon. The differences are more marked as the ion mass and the implant energy increase. This paper reviews work that has been done using high resolution (Laplace) Deep Level Transient Spectroscopy (DLTS) to try to understand(More)
