BACKGROUND Osteointegration of press-fit radial head implants is achieved by limiting micromotion between the stem and bone. Aspects of stem design that contribute to the enhancement of initial stability (ie, stem diameter and surface coating) have been investigated. The importance of total prosthesis length and level of the neck cut has not been examined. METHODS Cadaveric radii were implant...

prolonged excessive intake of fluoride during child's growth and development stages has been associated with mental and physical problems. the aim of this study was to investigate the effect of excessive fluoride intake on the intelligence quotient (iq) of children living in five rural areas in makoo/iran.in this cross-sectional study, 293 children aged 6-11 years were selected from five villag...

The range and midrange are widely used, particularly in statistical quality control as an estimator of the dispersion tendency. In fact, the range itself is a very simple measure of dispersion, gives a quick and easy to estimate indication about the spread of data. The extremal quotient is used in climatic study, industrial quality control, life testing, small-area variation analysis and the cl...

For Gorenstein quotient spaces C/G, a direct generalization of the classical McKay correspondence in dimensions d ≥ 4 would primarily demand the existence of projective, crepant desingularizations. Since this turned out to be not always possible, Reid asked about special classes of such quotient spaces which would satisfy the above property. We prove that the underlying spaces of all Gorenstein...

Leopardi introduced the notion of a Kronecker quotient in [Paul Leopardi. A generalized FFT for Clifford algebras. Bulletin of the Belgian Mathematical Society, 11:663–688, 2005.]. This article considers the basic properties that a Kronecker quotient should satisfy and additional properties which may be satisfied. A class of Kronecker quotients for which these properties have a natural descript...

the current study was after probing the would-be correlation between emotional intelligence (and its subcomponents), on the one hand, and metacognitive listening strategies used by academic efl learners, on the other. benefiting from 72 female and 40 male university students from urmia university, urmia azad university and salams azad university, the current study also strived to find the possi...
