Decay heat (DH) is the produced through a radioactive decay of fission products during or after reactor operation. It known as second largest source power in core fission. Being such strong contributor to power, it should be accurately determined at any time Currently, there are two main approaches for DH estimation used simulation codes. One approach based on careful inventorying all target nu...

the prevalence of exercise induced asthma (eia) in iran is not known. in the present study the  prevalence of  eia  among female students  of  guidance school  in the  city of mashhad was evaluated. a total of 1690 female students aged 12-14 years in ten randomly selected schools in north east of iran (mashhad) completed an asthma symptoms- specific questionnaire. one hundred forty four randoml...

This paper presents a new algorithm in the RAST family of algorithms. RAST algorithms perform geometric matching by exploring intersections between query regions and constraint sets in the space of possible model transformations. RAST algorithms are closely related to hierarchical Hough transformations but have more desirable geometric and combinatorial properties for object recognition applica...

Natural rubber latex (NRL) allergy has become an important occupational health problem in recent years. However, the prevalence of sensitization to NRL among allergic asthmatic patients is unknown. This study was undertaken evaluate the levels specific IgE in sera of 70 adult asthmatic patients (27 male and 43 female) with mild (32 patients) and moderate (38 patients) asthma, whose diagnosis wa...

In some patients, eosinophilic gastroenteritis(EG) occurs in those with food allergy. We experienced a non-atopic asthmatic who had an EG associated with food allergy to fish and eggs, and blood eosinophilia. A skin prick test and RAST to causative food allergens showed a negative result. A fiber-optic endoscopic biopsy from the gastric mucosa showed an intense eosinophilic infiltration. We cou...

BACKGROUND The peaking period for endurance competition is characterized for a relative increase of the intensity of training, after a longer period of training relatively dominated by lower intensity and higher volume. OBJECTIVES The present study was designed to compare physiological and 10 km performance effects of high intensity training (HIT) versus race pace interval training (RP) durin...

BACKGROUND Different fluoride formulations may have different effects on caries prevention. It was the aim of this clinical study to assess the fluoride content, provided by NaF compared to amine fluoride, in saliva and plaque. METHODS Eight trained volunteers brushed their teeth in the morning for 3 minutes with either NaF or amine fluoride, and saliva and 3-day-plaque-regrowth was collected...

BACKGROUND The prevalence of Alternaria Alternata (AA), a mold causing in children severe asthma is scarcely known, also due to the underdiagnosis of AA allergy, frequently due to multiple sensitizations to molds. OBJECTIVE To analyze this issue we prospectively studied all children attending our Division between January 4, 1990 and December 31, 1997. METHODS A total of 6840 children with a...
