BACKGROUND The purpose of this study was to evaluate the effects of topical nipradilol monotherapy for 5 years on intraocular pressure, visual field performance, and optic disk topography. METHODS Thirty patients with normal tension glaucoma were monitored for intraocular pressure every 1-3 months. A Humphrey visual field test and measurement of optic disk configuration using the Heidelberg r...

in this paper we study the long- term trend of energy intensity for iran. we use a quadratic function of the logarithm of income to take account of the change in trend of energy intensity and test the non-monotonic relationship between energy intensity and income during 1967- 2002 we find that the long-run coefficient on squared income is negative and significant, indicating a change in trend o...

A survey on opium use was earned out in Tinsukia district of upper Assam to assess the present prevalence and pattern of opium abuse and compared with earlier findings of the year 1981 (Baruah et al., 1995). A total of 75 addicts could be detected during the survey and 61 were interviewed using structured questionnaire. The results indicate significant decline in prevalence in opium use over th...

The analysis and presentation of climate observations is a traditional application of various visualization approaches. The available data sets are usually huge and were typically collected over a long period of time. In this paper, we focus on the visualization of a specific aspect of climate data: our visualization tool was primarily developed for providing an overview of temperature measurem...

Analysis of the long-term Global Aerosol Climatology Project data set reveals a likely decrease of the global optical thickness of tropospheric aerosols by as much as 0.03 during the period from 1991 to 2005. This recent trend mirrors the concurrent global increase in solar radiation fluxes at Earth's surface and may have contributed to recent changes in surface climate.
