objectives: there are various developmental screening tools that are different in terms of psychometric characteristics and choosing the best one is challenging for the pediatrician. this research was designed to identify the validity and reliability of parents evaluation of developmental status, a developmental screening questionnaire, in 4-60 months-old children in the city of tehran. methods...

We construct quasiconformal mappings in Euclidean spaces by integration of a discontinuous kernel against doubling measures with suitable decay. The differentials of mappings that arise in this way satisfy an isotropic form of the doubling condition. We prove that this isotropic doubling condition is satisfied by the distance functions of certain fractal sets. Finally, we construct an isotropic...

the spider mite, t. turkestani, is considered as one of the most important polyphagous pests of many crops. its reproductive ability, developmental time, preimaginal mortality and reproduction rate were determined on kidney bean at 20, 25 and 30°c,70±5% rh and 16l:8d. female longevity and immature developmental period (6.74 and 5.8 days, respectively) were shorter at 30°c than at 20 and 25°c. t...

The authors present the central capacity sharing (CCS) model and derive equations describing its behaviors to explain results from dual-task situations. The predictions of the CCS model are contrasted with those of the central bottleneck model. The CCS model predicts all of the hallmark effects of the psychological refractory period (PRP) pardigm: -1 slope of the PRP effect at short stimulus on...
