We have invented a quasi-Gaussian profile-transmittance filter based on radially varying the phase retardation in a birefringent element. The radial birefringent element has been applied to resonator design and has demonstrated its usefulness in generating an improved resonator spatial-mode profile.

influence of soil organic matter (som) on the adsorption, desorption and transport of polycyclic aromatic hydrocarbons (pahs) has already been given full investigation in soils. in this paper, confocal laser scanning microscope (clsm) was used to elucidate aqueous leaching of pahs in different types of soil with soil columns, which enhanced understanding on transport of pahs appreciably. four ...

The purpose of this study was to determine the relationship between knowledge parenting styles parents on children mental retardation. research method descriptive cross sectional approach. data collection technique used total sampling 44 respo...

Introduction: Metakaolin (MK) is used as supplementary cementitious material to reduce the CO 2 footprint of Portland cements. However, early hydration cement (OPC) often retarded due its use. The present work investigates mechanisms this retardation. Focus laid on interaction MK with main clinker phase C 3 S (Ca SiO 5 , pure form alite) that known govern kinetics OPC. Methods: Hydration reacti...

background chromosomal aberrations are one of the most common causes of mental retardation (mr). objectives in this study, in order to identify the rate of chromosomal abnormalities in idiopathic mr, 50 mr patients at a charity center in hamadan, iran, were investigated. methods fifty mentally retarded male patients without specific chromosomal abnormalities (e.g., down syndrome, fragile x synd...
