T2* decay is of much greater magnitude than T2 in tissues and results in more rapid signal loss as compared to the T2 relaxation.If one had a perfectly uniform magnet and an object without susceptibility effects, the T2 and T2* would be equal.he relationship between T2 and T2* can be illustrated by the multiecho spin echo sequence shown in Figure 2. The 180 degree RF pulses used to generate the echo are rephasing the spins that have undergone T2* decay. The gradual decline in signal from subsequent echos reflects T2 decay.
At 15 kWh, trading in a pre-1986 fridge for a new efficient one would save about $158 a year in electricity costs. And some older fridges are even worse than the average. One reader estimates her savings to be $238 per year for trading in her 1979 fridge for a 2004 model.ridge should be 36-40F, and the freezer should be 0-5F (-17 to -10C). Fridges set 10 degrees lower than needed (or freezers set 5 degrees lower than needed) can increase energy use by as much as 20-25%. Personally, I set my own fridge to 56 because as a vegan I never store super-perishables like meat or dairy.
3000 Max Watts: 600W Fridge Startup + 2000W AC Running + 400W Other 2600 Running Watts: 180W Fridge Running + 2000W AC Running + 420W Other. Needless to say, if you plan to use much more than your AC, fridge, and lights, you probably want a larger generator. Another important factor in buying a portable RV generator is noise level.
