nurses. The rate of transmission was between 6 and 10% to 158 newborns cared for in such a way that organisms from infant carriers could be transmitted to them only via the airborne route. In contrast, 126 infants who were handled by nurses who also handled the neighbouring carrier babies with little or no handwashing exhibited a 43 % rate of acquisition of the carrier strains. A careful hexach...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
One of the most important issues in structure-function relationship modeling is that each rangeland has numerous functions and each of them can provide the most benefits in a certain state of that ecosystem. In fact, relationship between structure and function can be varied in different states. After presentation of the Linear Structure-Function Model based on the Clementsian succession theory,...
The energies of the emission spectral lines originating from vacancies in deep atomic shells change if the elements are in different oxidation states. These changes of energies cause small shifts in spectral lines. For Sulfur and Magnesium, these shifts are shown in this work, and also the influence that they may have on the calibration of wavelength-dispersive spectrometers and in consequence,...
