This small book is the first of a series of occasional papers which are to be published under the auspices of the Institute for Research into Mental Retardation, and its author is the chairman of the Institute's Research Committee. In the preface, it is said to be aimed at an intelligent lay audience and it is suggested that 'it will be read with interest and profit by workers in the field of m...

A phase compensation method is presented for measuring the cell gap of reflective LCD. We use the so-called QHQ compensator that is made up of two quarter-wave plates (Q) and one half-wave plate (H). This method is different from other compensation methods in that we can change both the orientation angle and retardation value of the compensator by rotating the quarterwave and halfwave retarders...

We proposed a fabrication method of the patterned retarder based on the electrohydrodynamic (EHD) instability. The anisotropic flow of the liquid crystalline polymer (LCP) film enables a net force induced by utilizing the distorted electric field. The patterned retarder based on the EHD instability has simple process with an easy control of the phase retardation and no residual LCP. Therefore, ...

In a recent paper, we have shown that the flattening of galactic rotation curves can be explained by retardation. However, this will rely on temporal change mass. our previous work, kept only second order terms retardation time in analysis, while higher Taylor expansion where not considered. Here consider analysis to all orders and show indeed suffice, neglected.

Giant atoms are known for the frequency-dependent spontaneous emission and associated interference effects. In this paper, we study dynamics of a two-level giant atom with dynamically modulated transition frequency. It is shown that retarded feedback effect giant-atom system greatly modified by dynamical phase arising from frequency modulation retardation itself. Interestingly, such modificatio...

We report the second harmonic scattering experiments from acetonitrile liquid suspensions of two-dimensional metal dichalcogenide nanoflakes,: semiconducting MoS2 and WS2, metallic NbS2, semi-metallic ZrTe2. Because study is directly performed in phase, no symmetry breaking can be attributed to a supporting substrate as it often case investigation generation efficiency for these materials. A co...

mental retardation (mr) is one of the most frequently found major genetic disorders around the world, affecting 1-3% of the people in the general population. the recent advancement in molecular biology and cytogenetic study has made possible the identification of new genes for a variety of genetic disorders including autosomal recessive mr. recessive genetic disorders are common in pakistan due...

background :growth retardation in children is a result of nutritional ignorance, inappropriate care, and inadequate monitoring of growth monitoring. this study was performed to assess the effect of mothers education program based on the precede model on the mean weight of children (6-12 months) at health centers in shiraz, fars province.   methods : this quasi experimental study was conducted o...

fryns-aftimos syndrome is a rare autosomal dominant disorder characterized by craniofacial signs, anterior neuronal migration disorder (pachygyria, lissencephaly), skeletal deformities and mental retardation. we describe a five-year-old boy with abnormal facial features (hypertelorism, ptosis, high arched palate), skeletal problems (short stature, short fingers, flat feet) and mild intellectual...
