Background: Preterm birth and admission to neonatal intensive care unit as stressors can cause physiologicalinstability that may lead to prolong hospitalization and mortality. This study aimed to determine the effect of artificialnights and facilitated tucking on the physiological indices of premature infants.Methods: This randomized clinical trial was conducted on 60 preterm ...

Inter-annual variability in primary production and ecosystem respiration was explored using eddy-covariance data at a semi-arid savanna site in the Kruger Park, South Africa. New methods of extrapolating night-time respiration to the entire day and filling gaps in eddy-covariance data in semi-arid systems were developed. Net ecosystem exchange (NEE) in these systems occurs as pulses associated ...

Recent correspondence in the British Medical Journall-4 has discussed the need for oxygen-failure devices and the philosophy of their design, so we shall not repeat this discussion here. Briefly, however, we think that very occasional oxygen failures are inevitable, during both anaesthesia and artificial ventilation with oxygen. Because the danger is so remote any safety device that is to gain ...
