[1] We present adaptive optics data from the Keck telescope, taken while the Huygens probe descended through Titan’s atmosphere and on the days following touchdown. No probe entry signal was detected. Our observations span a solar phase angle range from 0.05 up to 0.8 , with the Sun in the west. Contrary to expectations, the east side of Titan’s stratosphere was usually brightest. Compiling ima...

We have studied the vertical structure of hazes at six different latitudes (−60◦, −50◦, −30◦, −10◦, +30◦, and +50◦) on Saturn’s atmosphere. For that purpose we have compared the results of our forward radiative transfer model to limb-to-limb reflectivity scans at four different wavelengths (230, 275, 673.2, and 893 nm). The images were obtained with the Hubble Space Telescope Wide Field Planeta...

PURPOSE To evaluate postoperative pain, corneal epithelial healing, development of corneal haze, refractive outcomes, and corneal aberrations in a novel one-step, modified transepithelial photorefractive keratectomy (PRK), termed All-surface laser ablation (ASLA), compared to conventional, alcohol-assisted PRK. MATERIALS AND METHODS Sixty eyes of 30 myopic patients were prospectively recruite...

in iran, there are about 10% losses in black tea processing, which is called tea dust. tea dust is produced through black tea screening, during the last stage of production. in this research, regarding the increasing demand for new beverages, the production of iced tea beverage using black tea dust was investigated. process of iced tea involved tea solid extraction and then mixing with edible a...

Aims: Selective laser trabeculoplasty (SLT) (Lumenis, Santa Clara, CA) was developed in 1999 as a means to lower IOP in patients with glaucoma. It is a relatively safe procedure. We report a rare side effect of corneal opacity and stromal haze with corneal thinning and hyperopic shift following SLT. Presentation of Case: Case report. Results: A 50 year-old Asian male who underwent SLT OD develo...

The variations of visibility, PM mass concentration and mixing layer height (MLH) at four major urban-industry regions (Shenyang, Anshan, Benxi and Fushun) in multi-cities of central Liaoning over northeast China were evaluated from 2009-2012 to characterize the dynamics effect on air pollution. The annual mean visibilities were about 13.7±7.8km, 13.5±6.5km, 12.8±6.1km and 11.5±6.8km in Shenyan...

In this paper, we propose a general algorithm to removing haze from single images using total variation minimization. Our approach stems from two simple yet fundamental observations about haze-free images and the haze itself. First, clear-day images usually have stronger contrast than images plagued by bad weather; and second, the variations in natural atmospheric veil, which highly depends on ...

Ultra-thin flexible glass with high transparency is attractive for a broad range of display applications; however, substrates with low optical haze are not ideal for thin film solar cells, since most of the light will go through the semiconductor layer without scattering, and the length of light travelling path in the active layer is small. By simply depositing a layer of TEMPO (2,2,6,6-tetrame...

This study evaluated the effect of onion extract on corneal haze suppression after applying the air assisted lamellar keratectomy. The air assisted lamellar keratectomy was performed on 24 canine eyes. They were treated with an artificial tear (group C), prednisolone acetate (group P), onion extract (group O) and TGF-β1 (group T) three times per day from 7 to 28 days after the surgery. Corneal ...
