The influence of different yeast (Saccharomyces cerevisiae) cellular fractions was studied in an attempt to gain knowledge on the feasibility of trehalose crystallization in yeast cells. Certain constituents of S. cerevisiae cells inhibited/delayed trehalose crystallization upon humidification at high relative humidities.

Proximal airway humidity was measured during mechanical ventilation in 14 infants using an electronic hygrometer. Values below recommended minimum humidity of adult inspired gas were recorded on 251 of 396 occasions. Inadequate humidification, largely due to inadequate proximal airway temperature, is commoner than recognised in infants receiving mechanical ventilation.

Introduction: Synthetic Mg-and Fe-silicate smokes simulate material in the dusty circumstellar envelope of asymptotic giant branch stars [1], presumably a raw material for planet formation. When immersed in water, Mg-silicate smokes react within days to produce proto-phyllosilicates observable under the electron microscope (EM) [2-4]. Water-immersed Fe-silicate smokes react more slowly [3, 4] a...

The objective of this study was to modify an existing liquid desiccant and indirect/direct evaporative cooling-assisted 100% outdoor air system (LD-IDECOAS) for humidification operation in winter. energy benefit the desiccant-assisted approach during LD-IDECOAS over conventional method with a steam humidifier evaluated through detailed simulation. enthalpy effectiveness values measured from lab...
