B 1 -based specific energy absorption rate determination for nonquadrature radiofrequency excitation
Specific absorption rate distribution evaluation in a different substrate for hyperthermia treatment
Hyperthermia treatment procedure (HTP) isatreatment that uses high heatgenerated from electromagnetic (EM) waves, which is about 42 °C to 45 within a particular duration. However, poor focus position distance on the treated tissue has become significant concern among researchers since it may contribute wide area of unwanted hot spots, lead severe adverse health effects healthy tissue.This paper...
BACKGROUND AND PURPOSE Fast spin-echo short τ inversion recovery sequences have been very useful for MR imaging-guided deep brain stimulation procedures in Parkinson disease. However, high-quality fast spin-echo imaging deposits significant heat, exceeding FDA-approved limits when patients already have undergone deep brain stimulation and need a second one or a routine brain MR imaging for neur...
predation rate is basic to any investigation of prey-predator interaction and a major component in the selection of predators for biological control. the predation rate of variegated lady beetle, hippodamia variegata (goze), fed on different densities (20, 40, 60, 80 and 100) of third instar nymphs of cotton aphid, aphis gossypii glover, was studied under laboratory conditions (25 ± 1 °c, 65 ± ...
