Even though neurofibromatosis ( NF) is not a rare neurological disorder, but there is few studies regarding  the relationship between  NF and psychological disorders. A 14 year old girl with NF type 1 associated  with multiple cerebral lesions was admitted in psychiatric ward due to restlessness , hypertalktiveness aggressive behavior, and flight of idea. Psychiatric diagnosis, based on DSM IV ...

Often when fuel prices rise as they have during 2005, weights and measures officials see an increase in the number of complaints related to the accuracy of gasoline pumps (retail motor-fuel dispensers). Frequently, weights and measures jurisdictions report receiving consumer complaints from motorists who believe they filled their vehicle's fuel tank with more gasoline than the tank is specified...

Introduction: The conversion and storage of energy with a high efficiency, especially a high specific energy, will be an important factor in future energy storage technologies. The relatively simple possibility to store hydrogen and oxygen with high specific energy combined with high energy conversion efficiency in fuel cells and electrolyser presents an opportunity for the use of polymer elect...

To assure safe shutdown of a nuclear power plant, there must always be reliable means of decay heat removal provided, in last resort, by an Emergency Core Cooling System (ECCS). Currently the majority of nuclear power plants in the US utilize diesel generator sets as on-site emergency power generating units. In addition to the loss of off-site power, plants can lose their on-site AC power, a co...

This paper discusses belief revision under uncertain inputs in the framework of possibility theory. Revision can be based on two possible definitions of the conditioning operation, one based on min operator which requires a purely ordinal scale only , and another based on product, for which a richer structure is needed, and which is a particular case of Dempster's rule of conditioning . Besides...

conclusions the combination of intravenous paracetamol 1 gr and ketamine 0.5 mg/kg resulted in an overall reduction in pain scores, decreased postoperative analgesic requirements, and lower agitation score compared with intravenous paracetamol 1 gr and tramadol 0.7 mg/kg for patients undergoing renal surgery. results postoperative pain scores were significantly lower in the pk group than in the...

Pebble bed reactors fuel elements are specially suited for withstanding very high burn-up values. This is one of the main characteristics of a transmutation fuel. The higher the burn-up achieved in the fuel, the smaller the number of reprocessing steps needed for obtaining a high transmutation rate. In this paper, a new transmutation cycle option will be introduced, based in a single pass of th...

Introduction The latest studies of the overall characteristics of hypersonic flying vehicles with airbreathing engines have shown that these vehicles are fairly promising. Some additional problems arise, however, that are related to the definition of the general shape of the aircraft, the choice of propulsion type and operation regimes, the engine size and position on the aircraft body. There h...
