Abstract: This study is carried out to describe the behaviour of vehicles flow on the road, in the presence of blocking effects. A non-linear three dimensional system of ordinary differential equations is used to describe vehicles flow on the road. The study classify total vehicles population on the road into three compartments as Free – Slow – Released vehicles. The formulated model is well-po...

Using the calculation of coefficients multiple linear regression two-dimensional correlation, we studied mutual influences (functional connectivity) between amplitudes EEG rhythms in people with mental retardation. Multiple equations were geometrically interpreted using polycyclic multigraphs. As a result studies and calculations, it was found that retardation, number correlation is determined ...

the hereditary ataxias are a group of genetically defined neurological diseases which are characterized by heterogeneous clinical presentations. ataxia is defined as imbalance and lack of coordination. mental retardation associated with ataxia has been reported in some of the known and recently identified syndromes. in this review, we describe some known and novel genes that cause familial ment...

The ability of individuals with mental retardation to focus on task-relevant elements of complex visual arrays and increase visual-search efficiency was investigated. Initial assessments of visual-search efficiency were conducted to identify pairs of features for the form and size dimensions for which each participant demonstrated serial search. Subsequently, color was added as a defining featu...

this is a discriptive study with the main goal to identify personal, pregnancy and delivery characteristics of mothers given birth to mentally retarded child. this study has been conducted in the rehabilitation center in tehran in 1994. a total of 150 women took part in this research, and the tool of was a check list which was completed by researcher through interview. the findings were illustr...

materials and methods a number of 100 patients with imr, normal karyotypes and negative fragile-x and metabolic tests were screened for subtelomeric abnormalities using mlpa technique. results nine of 100 patients showed subtelomeric abnormalities with at least one of the two mlpa kits. deletion in a single region was found in 3 patients, and in two different subtelomeric regions in 1 patient. ...

We evaluated the presence or absence of informative morphogenetic variants in cases with mental retardation compared with mentally healthy subjects. Cases diagnosed with mental retardation were matched by age and sex with control subjects and examined for the presence of informative morphogenetic variants. The aim of the study was to investigate their prevalence and mean number in these subject...

The effectiveness of a video feedback and self-management package was assessed with various inappropriate behaviors exhibited by six youth with mild mental retardation. The procedure consisted of (a) videotaping participants' inappropriate behavior, (b) having them self-monitor and record their behavior, (c) prompting them to evaluate their behavior against a criterion, and (d) allowing to rein...
