several practical problems of hypotheses testing can be under a general linear model analysis of variance which would be examined. in analysis of variance, when the response random variable y , has linear relationship with several random variables x, another important model as analysis of covariance can be used. in this paper, assuming that y is fuzzy and using dlr metric, a method for testing ...

Foraminifera are single-celled organisms with internal calcerous shells, known as tests. The image above shows a shell with a planispiral chamber arrangement — during growth, chambers are added sequentially to form a coil in a flat spiral. Foraminiferan tests are quite diverse. The image shown here came from a study on the nature of the material in the calcerous test and how the foraminifera de...

allergy diagnosis needs to be improved in polysensitized patients due to the existence of possible confounding factors in this type of patients. component resolved diagnosis (crd) is a new concept in the investigation of polysensitized patients. the aim of this study was to evaluate if the utilization of immunocap isac improve the diagnosis of the polysensitized allergic rhinitis patients. skin...

nowadays the surface texturing has been widely recognized as a usable capability to improve the tribological systems. in this paper, ultrasonic assisted turning (uat) isperformed to create the micro textures on the flat faces. micro surface texturing ismade on the al7075-t6 by the uat in the face turning process. then, the influences of cutting speed feed, vibration direction and vibration ampl...

background and aims. adding further fillers to dental resins may enhance their physical characteristics. the aim of this study was to evaluate the tensile strength of heat-curing acrylic resin reinforced by tio2 nanoparticles added into the resin matrix. materials and methods. commercially available tio2 nanoparticles were obtained and characterized using x-ray diffraction (xrd) and scanning ele...

the aim of this study was to evaluate the utility of a proficiency testing program among limited number of local laboratories as an alternative to the iupac/citac guide on proficiency testing with a limited number of participants, specially where international schemes are not accessible. as a sample scheme we planned to determine aflatoxins (b1, g1, b2, g2, total) in iranian pistachio matrix. a...
