purpose : to evaluate distance and near contrast sensitivity (cs) under photopic and mesopic conditions before and after refractive lens exchange (rle) and implantation of the aspheric acrysof restor (sn6ad3 model) intraocular lens (iol) methods : sixty eyes of 30 consecutive patients after rle underwent bilateral implantation with the aspheric acrysof restor iol. the patients sample was divide...

conclusions in cases of unusual vascular lesions, metabolic diseases must be considered. in homocystinuria, early diagnosis and treatment are important. blood homocysteine levels can be returned to normal, and some complications can be prevented. introduction homocystinuria is a hereditary disease caused by a defect in the enzymes involved in metabolizing methionine. homocystinuria can influenc...

introduction: consumption of morphine, during pregnancy, in addition to inducing defects in the mother’s nervous system function, caused defects or delays in the formation and evolution of embryonic visual system. in the present study, changes in lens development were assessed in embryos exposed to morphine in utero. methods: female wistar rats (250-300 g) were mated with male rats and pregnanc...

background: cutaneous leishmaniasis caused by l. major is an important public health problem in endemic areas. the aim of this study was to explore the therapeutic effect of microwave and or infrared radiation in the treatment of lesion induced in balb/c mice by l. major inoculation. methods: the footpad lesion was induced in balb/c mice by inoculation of l. major promastigotes subcutaneously. ...

Velocity fields can be reconstructed at cosmological scales from their influence on the correlation between cosmic microwave background and large-scale structure. Effects that induce such correlations include kinetic Sunyaev Zel'dovich (kSZ) effect moving-lens effect, both of which will measured to high precision with upcoming cosmology experiments. Galaxy measurements also provide a window int...

The aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. A 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. The dog was bitten by a snake nearly 4 months ago. A 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. In the left eye, posterior synechia was detected in the ...

The influence of microwave treatment on the surface roughness, hydrophobicity, and chemical composition of galena was studied. The pure galena specimens and purified galena concentrate were used in this work. A conventional multi-modal oven (with a frequency of 2.45 GHz and a maximum power of 900 W) was used to conduct the experiments. The results obtained from the atomic-force microscopy analy...

Strong lensing time delays can measure the Hubble constant H 0 independently of any other probe. Assuming commonly used forms for radial mass density profile lenses, a 2% precision has been achieved with seven Time-Delay Cosmography (TDCOSMO) in tension from cosmic microwave background. However, without assumptions on – and relying exclusively stellar kinematics to break mass-sheet degeneracy d...

Abstract we present a printed lens for radar applications. The structure of the presented consists an array modified micro-strip lines, which is positioned in antenna’s aperture on same planar substrate. Simulations show that gain and directivity increase with proposed wide band frequency band. design insensitive to rotation antenna. This paper focuses real industrial applications problems. Fur...

the lens plays important role in dielectric resonator antenna (DRA) for increasing bandwidth and directivity. Also, liquids like water ethanol can be noticed developing DRA THz application. In addition, are interesting because level quality of material used designing reconfigurable antenna. For spectrum, combined with microwave devices by Microfluidic technology. this paper, suggested is to enh...
