Revised time-of-flight calculations for high-latitude geomagnetic pulsations using a realistic magnetospheric magnetic field model [PDF]
, 2005 We present a simple time-of-flight analysis of Alfvén pulsations standing on closed terrestrial magnetic field lines. The technique employed in this study in order to calculate the characteristic period of such oscillations builds upon earlier time-of ...

Synthesis of Multi-period Heat Exchanger Network Considering Characteristics of Sub-periods
Chemical Engineering Transactions, 2015 To reduce computational loads for synthesis of multi-period Heat Exchanger Network (HEN), two methods, including a representative period method and a stepwise simplifying method, are proposed by considering the sub-period characteristics. In the representative period method, a representative period is selected, and the optimal HEN structure in this sub-

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.
