PURPOSE To study the mechanical dynamics between the zonuli-capsular complex and an accommodating intraocular lens mechanics simulator using pharmacological stimulation of the ciliary body in a primate eye. METHODS Following phacoemulsification removal of the lens, force/movement gauges simulating the accommodating intraocular lens mechanics were implanted in 8 primate eyes (4 positioned in-t...

The type of the vacuum is studied numerically in the maximally Abelian (MA) gauge and in the Landau (LA) gauge of SU(2) gluodynamics. The type of the vacuum is determined by a ratio between the dual coherence and the dual penetration lengths. The dual penetration length is determined from correlations between Wilson loops and electric fields in both gauges. The dual coherence length is found fr...

MODIS, the Moderate Resolution Imaging Spectroradiometer (MODIS), is scheduled for launch in late 1998 or 1999 aboard the first Earth Observing System (EOS) platform. Global, daily snow-cover maps with a spatial resolution of 500 meters will be produced from MODIS data using a fully-automated and computationally-frugal snow-mapping algorithm. Recently, modifications to the original snow-mapping...

Snow cover plays a crucial role in surface hydrology and energy balance, especially in the Qinghai-Tibetan Plateau (QTP). This study used 12 years (2000–2011) of ground-observed snow depth at 87 meteorological stations to assess and verify the accuracy of the daily cloud-free snow-cover product from the Moderate Resolution Imaging Spectroradiometer (MODIS) over the QTP. On average, the daily cl...

However, sampling snow density is a difficult and time consuming task, which explains why few previous studies have analyzed the spatial variability of snow density. In this study we analyzed snow density measurements made in February...

At winter the problem that how to efficiently clear solid ice and snow, which always plagues the staff .The interfacial materials—solid snow-ice— cause the major operational problem related to snow removed performance. The central issue is how to evaluate the yield characteristics when the solid snow-ice was broken and fracture failure. Measurement system of freezing adhesive yield characterist...

A rain gauge network should serve general as well as specific purposes such as water supply, hydropowergeneration, flood forecasting, irrigation, and flood control. The level of accuracy a network can achieve depends onthe number and locations of gauges in the network. In this study, a rain gauge network was designed for Hormozganprovince in the south of Iran. Monthly rainfall totals from 124 r...
