Several options for designing fast reactors to operate in the Breed-and-Burn (B&B) mode are compared and a strategy is outlined for early introduction of B&B reactors followed by a gradual increase in the fuel utilization of such reactors. In the first phase the fast reactor core will consist of a subcritical B&B blanket driven by a relatively small critical seed. As the required discharge burn...

Only electrokinetic system and its effect on the inactivation of pathogenic organisms in biosolids were investigated. Bench scale experiments were conducted in a series of electrokinetic (EK) reactors. Ten EK reactors were set up with different types of sewage sludge: primary, secondary (attached growth culture), secondary (activated sludge), and anaerobically digested sludge, coming from Auteu...

liver functional tests due to inflammatory process which induced by cholecystitis might changed and some clinicians suggested that these changes might help us to stone prediction in common bile ducts and decrease hazards of performing ercp and other invasive procedures. present study was performed for assessment of role of liver functional test in diagnosis of common bile duct stone in patients...

bloody nipple discharge in infancy has rarely been reported in medical literature. we report a 7 month-old female infant with a one month history of bilateral nipple discharge. endocrinologic and hematological workups were within normal limits. breast ultrasonography showed two non-echogenic cystic areas in each breast. the problem resolved after a period of observation. this is a benign condit...

We examined the relations between bronchial reactivity, baseline FEV1, and annual decline of height corrected FEV1 (delta FEV1/ht3) over 7.5 years in 227 men (117 smokers, 71 ex-smokers, and 39 non-smokers). Men with a clinical diagnosis of asthma or receiving bronchodilator treatment were excluded. Bronchial reactivity was determined as the provocation concentration (PC20) of inhaled histamine...

Recent measurements of the positron energy spectrum obtained from inverse beta decay interactions of reactor electron antineutrinos show an excess in the 4 to 6 MeV region relative to current predictions. First-principles calculations of fission and beta decay processes within a typical pressurized water reactor core identify prominent fission daughter isotopes as a possible origin for this exc...
