abstract   presently, there have been many new techniques and performance methods evolved in the process of creating stage atmosphere; and subsequently in stage deign. the dominating atmosphere and scenography receives more attention in the modern pieces and plays and for that reason, stage designers use modern and new technologies in stage creation. there are many significant pioneers in this ...

photorefractive keratectomy (prk) is a safe and effective surgical keratorefractive technique which is done with the application of mitomycin-c (mmc) in cases of high myopia to prevent the formation of corneal haze this study was conducted to evaluate 3-year visual acuity and quality outcomes of prk-mmc in high myopia. this before-after study was conducted on 20 individuals (40 eyes) with myopi...

objectives: the visual-motor skill is one of the major factors in the learning process. visual-spatial and visual analysis skills are components of the visual motor skill. any deficiency in visual-motor skills and their components often causes problem in writing and learning processes in children. the aim of this study was to investigate the effect of occupational therapy (o.t.) intervention on...

Long-baseline interferometry at optical and near-infrared wavelengths is an emerging technology which is quickly becoming a useful tool to investigate stellar atmospheres and to compare observations with models. Stellar atmosphere models have so far mainly been constrained by comparisons with stellar spectra which are integrated over the stellar disks. Interferometric observations provide spati...

The effect of hydrostatic pressure (0.1-54 MPa, equivalent to pressures experienced by fish from the ocean's surface to depths of ca. 5,400 m) on visual pigment absorption spectra was investigated for rod visual pigments extracted from the retinae of 12 species of deep-sea fish of diverse phylogeny and habitat. The wavelength of peak absorption (lambda(max)) was shifted to longer wavelengths by...

Photochemically produced aerosols are common among the atmospheres of our solar system and beyond. Observations and models have shown that photochemical aerosols have direct consequences on atmospheric properties as well as important astrobiological ramifications, but the mechanisms involved in their formation remain unclear. Here we show that the formation of aerosols in Titan's upper atmosphe...

A new approach for the study of the pollution of operating theatre atmospheres by volatile anaesthetic agents is described. Disadvantages of earlier work are discussed together with ways in which they may be overcome. Some pitfalls in analysis, sampling and standardization are indicated and some hazards of incorrect data interpretation are shown. The need for a cautious and critical attitude is...
