Stockpiling Ventilators for Influenza Pandemics

In preparing for influenza pandemics, public health agencies stockpile critical medical resources. Determining appropriate quantities and locations for such resources can be challenging, given the considerable uncertainty in the timing and severity of future pandemics. We introduce a method for optimizing stockpiles of mechanical ventilators, which are critical for treating hospitalized influen...

Abstract Supersonic Rotation in the Maryland Centrifugal Experiment

The Maryland Centrifugal Experiment (MCX) has been built to study the confinement of supersonically-rotating plasmas and velocity shear stabilization of MHD instabilities. Theory predicts improved stability and confinement when a strong radial electric field is introduced into a magnetic-mirror geometry. The resulting radial currents establish a stable highly sheared plasma rotating at superson...

EHPnet: Mines, All Mines

The presence or absence of an oestrogen receptor-related antigen in breast tumours has been examined histochemically using a monoclonal antibody ('D59 Coffer & King, 1981). In frozen sections, fixed either by the method of Tamura et al. (1980) or in methanol, staining was apparent in 14/24 (58%) and 22/26 (85%) of the breast cancers respectively. In paraffin sections fixed in ethanol, staining ...

Portable ventilators

Mechanical ventilators used in intensive care units are sophisticated devices. The guiding principle in their design is the provision of optimal lung ventilation. They incorporate precise but sizeable pneumatic components intended to utilize piped gases and mains electricity. However, when transporting patients receiving ventilatory support, these devices are rarely suitable because of their si...
