Respiratory Metabolism in Infancy and in Childhood

Abstract

Quantitative measurements of the water exchange of premature infants are essential for defining their fluid requirements because of their weak appetites and because factors other than feeding contribute so much to their well-being. This paper presents the results of such measurements made on 12 premature infants fed varying diets but studied under constant environmental conditions. APPARATUS AND METHODSA detailed description of the methods employed for analysis of the diet and excreta (urine and feces), for measurement of the twenty-four hour insensible loss from skin and lungs, for determination of the daily respiratory exchange and for calculation of the composition of the metabolic mixture was given in previous papers.

Blueshifts in Emission Line Spectra of Quasi Stellar Objects

“…On the other hand, Putsil'nik [10] demonstrated the possibility of ``large violet shifts'' in an appreciable proportion of then known QSOs by pointing out that the identi¢cation of a pair of observed spectral lines with UV lines CIII] 1909 and MgII 2798 for measuring redshifts may actually be a misident-i¢cation for IR lines Pb 12818 and Pa 18751, respectively. Furthermore, it was shown by Gordon [11] that high speed QSOs resulting from relativistic ejection from parent galaxies may lead to an appreciable fraction to exhibit blueshifts. Again, Narlikar and Subramanian [12,13] predicted a small but non-zero fraction of blueshifted QSOs from consideration of the Doppler hypothesis, and while suggesting the possibility of misidenti¢cation of observed spectral lines in some QSOs, recommended a thorough search for blueshifted spectral lines.…”
