Polyvinylidene fluoride–trifluoroethylene as a reservoir for absorbed water
The absorption of water in Langmuir–Blodgett fi lms of ferroelectric copolymers of polyvinylidene fl uoride with trifl uoroethylene is shown to depend upon the fi lm thickness. This water absorption can have a profound effect on the dielectric properties of the copolymer fi lms.
متن کاملWater as a reservoir of nosocomial pathogens.
Understanding the means of acquisition, sources, and reservoirs of nosocomial pathogens is crucial for developing methods to reduce the incidence of nosocomial infections. The article in this issue by Graman et al1 highlights the continued importance of the environment, especially water sources, as a reservoir for nosocomial pathogens. Important water reservoirs in the hospital include potable ...
متن کاملBus water storage tank as a reservoir of Legionella pneumophila.
Health concerns associated with Legionnaires' disease have been identified as an area of the increasing public and professional interest. Any natural water or man-made water systems worldwide might be reservoirs of Legionellae. We presented a sporadic, community-acquired case of Legionnaires' disease caused by Legionellapneumophila serogroup 1 in a bus driver who used water for hand and face wa...
متن کاملA Sealed Water Calorimeter for Measuring Absorbed Dose
National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 The NIST sealed water calorimeter is intended for direct measurement of absorbed dose to water. This calorimeter was used for a series of approximately 3700 measurements to investigate the so-called heat defect, that is, anomalous endothermic or exothermic effects caused by dissolved gases. The three systems investigate...
متن کاملPolyvinylidene Fluoride Hollow Fiber Membrane Contactor Incorporating Surface Modifying Macromolecule for Carbon Dioxide Stripping from Water
Porous surface modified polyvinylidene ïuoride (PVDF) hollow fiber membranes are fabricated through a dry-wet phased inversion process. Surface modifying macromolecules (SMM) (1 wt. %) are used as additives in the spinning dope. The performance of the surface modified membrane in contactor application for CO2 stripping from water is assessed through the fabricated gas–liquid membrane contacto...
