OBJECTIVE To investigate the clinical and sociomedical outcome in patients with various clinical manifestations of humidifier disease and work related asthma after removal from further exposure. METHODS Follow up investigation (range 1-13 years) of respiratory symptoms, spirometry, airway responsiveness, sickness absence, and working situation in patients with (I) humidifier fever (n = 12), (...

A melt flow indexer (MFI) was used to investigate high-temperature transitions in melts of high-density polyethylene (HDPE). The MFI data were obtained in the range 190–230°C. These transitions were found in the MFI at about 210 and 225°C and reproduced in a Haake melt blender. Polystyrene was used in the blender experiment to demonstrate typical amorphous behavior. For HDPE melts, the MFI–temp...

unheated CO2 (U-CO2) in laparoscopic patients. Efficacy data were derived from a published randomised controlled trial reporting on the proportion of patients with hypothermia, a US database analysis of hypothermia patients for open surgery, and from an unpublished UK NHS before and after study of laparoscopic surgery patients. Other parameter inputs were obtained from published literature. Det...

Two summer outbreaks of humidifier fever (HF) are described in a microprocessor factory (factory A) and a printing factory (factory B). The air in each factory was humidified intermittently and controlled by present humidistats operating to maintain a relative humidity of 45% by an air handler incorporating a spray humidifier in factory A and two ceiling mounted spray humidifiers in factory B. ...

A humidification–dehumidification desalination system powered by low-grade waste heat energy (45 °C–70 °C) was experimentally investigated. The seawater directly utilized as coolant (25 for the dehumidifier preheated latent recovery from water vapor produced humidifier. effect of key performance-contributing factors such mass flow rate and temperature air feed at inlets humidifier were evaluate...

Scale-up of mixing operations continues to present a concern to the pharmaceutical development process. There liable scaling of a process requires an understanding of the effects that processing parameters may illicit on intermediateand finished-product properties. V-blenders, tote blenders, and double-cone blenders are examples of batch blenders that vary in geometric design .For these systems...
