Estimating water saturation via conventional logging tool such as resistivity cannot provide an accurate solution in a formation with low conductivity and tight porosity. As alternative, we employed dielectric permittivity, which makes it easy to differentiate the from other fluids pore structures. A multichannel frequency is used for measuring situ permittivity. To simulate two analytic models...

BACKGROUND Anesthesiology requires performing visually oriented procedures while monitoring auditory information about a patient's vital signs. A concern in operating room environments is the amount of competing information and the effects that divided attention has on patient monitoring, such as detecting auditory changes in arterial oxygen saturation via pulse oximetry. METHODS The authors ...

It remains uncertain whether neuromonitoring reliably predicts outcome in adult post-cardiac arrest patients in the early stage treated with therapeutic hypothermia. Recent reports demonstrated a regional cerebral oxygen saturation of cardiac arrest patients on hospital arrival could predict their neurological outcome. There has been little discussion about the significance of regional cerebral...

Colorimetric sensing techniques for point(s), linear and areal array(s) were developed using image sensors novel processing software chemical, biological medical applications. Monitoring recording of colorimetric information on one or more specimens can be carried out by specially designed software. The real-time monitoring recorded images video clips analyzed line(s) area(s) interest manual au...

Takayasu's arteritis (TA) is a chronic inflammatory disease involving the aorta. Because TA sometimes involves cerebral arteries, anesthetic debates focus on cerebral monitoring. There is limited evidence as to which cerebral monitoring method is most adequate. Furthermore, there is insufficient evidence to determine which anesthetic technique is better for TA parturients. We experienced the ca...
