A 54-year-old male patient, receiving maintenance hemodialysis for 8 years, is reported. Acquired cystic disease of the kidney (ACDK) had already been detected by routine abdominal imaging ...procedures. The patient complained of severe left flank pain and was admitted to our hospital. CT scanning revealed massive left perinephric hematoma. We performed transcatheter arterial embolization of the left renal artery but there was no renal tumor detected by abdominal imaging procedures, such as angiography, CT and MRI. The posttreatment course was uneventful and the patient continues to be maintained on hemodialysis.
Thermal characteristics are discussed for a roof snow melting system equipped with a heat exchanger to extract the thermal energy from the well water pumped up from the aquifer where the waste heat ...from a cooling tower for the air conditioning of the station building during summer is retrieved and stored. And also a water heat-source heat pump, a thermal storage tank, and a conventional water heater set at Nagaoka station of Joetsu Shinkansen Line are discussed. The field experiments indicated that a heat reclamation efficiency in the aquifer thermal energy storage was 40% and that a coefficient of performance of the water heat-source heat pump was 7.5. The system utilizing natural energy for the roof-snow melting is quite promising because of its high energy-saving performance of up to 26%.
