Abstract Multi-recycling HTGR has been investigated by JAEA in order to reduce the environmental burden and non-proliferation of Pu. In previous study, it is found that all actinoids except neptunium, which not problematic from viewpoint toxicity proliferation, can be recycled. However, cycle length slightly decreased compared with uranium fueled core due cumulated fertile TRU fuel composition....

Introduction:Amphetamines are central nervous system (CNS) stimulant substances and amphetamine abuse is considered a growing problem in our country. Previous studies revealed destructive effects of amphetamines on metabolism, perfusion and structure of brain. The aim of current study was evaluating regional cerebral blood flow (rCBF) disturbances in methamphetamine (MA) abuser...
