Experimental domain: the experimental ‘area’ that is investigated (defined by the variation of the experimental variables). Factors: experimental variables that can be changed independently of each other Independent Variables: same as factors Continuous Variables: independent variables that can be changed continuously Discrete Variables: independent variables that are changed step-wise, e.g., t...

The objective of this work was to develop bioadhesive topical gel of Aceclofenac with the help of response-surface approach. Experiments were performed according to a 3-level factorial design to evaluate the effects of two independent variables [amount of Poloxamer 407 (PL-407 = X1) and hydroxypropylmethyl cellulose K100 M (HPMC = X2)] on the bioadhesive character of gel, rheological property o...

Objective: To determine whether the missing canals in endodontically treated single-rooted teeth with two-canals are present either buccal or lingual/palatal for Turkish subpopulation. Methods: High-quality cone-beam computed tomography scans of 1297 belonging to 782 adults over age 18 were obtained from archive a dental clinic. Within this dataset, 129 had undergone endodontic treatment and po...

this article examines the basic assumption of rational expectations hypothesis on iran's economy from 1966 to 2003. this assumption suggests the neutrality or ineffectiveness of money policy on the development of real variables of production and employment. the results from estimation of production equation do not support the significant influence of unanticipated component of money growth...

Periodic random environments and mechanisms of their effect on imbedded random variables are discussed. The variables under consideration represent either waiting time until some event occurs or the number of events within a given time interval. Their probability distributions have periodic residual lifetime functions and periodic failure rates. The form of the corresponding cumulative distribu...

Explored informant differences and assessed the importance of sociodemographic factors, child health status characteristics, and caregiver burden to variability in psychological symptoms among caregivers to 116 children with chronic medical conditions. Important informant effects were found. Caregiver-reported, but not physician-reported, burden was an important predictor. Severity of illness, ...
