Climate change is a global issue that has impact on every living being in the world. Since Malaysia is located in the tropical area where there is no distinct four seasons, analysing rainfall has therefore become one of the common assessment tools for climate change. In this study, rainfall trends and spatial variations of Langat River Basin will be determined for the period of 1971-2012. Only ...

purpose : evaluating the effects of memantine on visual function after scleral buckling for rhegmatogenous retinal detachment (rrd) methods : in a double blind prospective randomized clinical trial, 61 patients with clinical diagnosis of less than 4 weeks macula-off rrd who had successful scleral buckle surgery had been selected and divided into two randomized groups. thirty of them received 5 ...

purpose: to evaluate the anatomical and functional outcomes of using heavy silicone oil as an internal tamponade for complicated cases of retinal detachment associated with proliferative vitreoretinopathy involving inferior retinal quadrants methods: 55 eyes from 55 patients with complicated retinal detachments enrolled in this interventional case series study. all eyes underwent standard three...

purpose : to evaluate the efficacy of autologous plasmin in pediatric vitrectomy and to report the anatomic outcomes of autologous plasmin assisted pediatric vitrectomy methods : in an interventional prospective study, thirty-four pediatric patients with vitreoretinal disorders who needed vitrectomy during 2008 to 2010, included in the study. the patients were divided into two groups: the retin...

Projected changes in the future rainfall of the Sydney metropolitan region were investigated through fine scale (2km grid) dynamical downscaling from a single global climate model (GCM) simulation using the Weather Research and Forecasting (WRF) regional climate model. Projections of rainfall (20402059) were compared with a reanalysis-driven simulation for the period 1990-2009. There are projec...

Rainfall infiltration exerts great effect on the stability of soil slopes. Based on the actual rainfall data, saturated-unsaturated seepage theory and the mechanical theory of unsaturated porous media, numerical simulations were conducted to examine the seepage field of saturatedunsaturated slope during rainfall infiltration in this paper. The influence of the coefficient with rainfall duration...

We completed a meta-analysis of regional and global climate model simulations (n=96) of the impact of Amazonian deforestation on Amazon basin rainfall. Across all simulations, mean (±1σ) change in annual mean Amazon basin rainfall was 12 ± 11%. Variability in simulated rainfall was not explained by differences in model resolution or surface parameters. Across all simulations we find a negative ...

Rainfall erosivity is the potential ability for rainfall to cause soil loss. The purpose of this study was to estimate the rainfall erosivity index for the Ghana Atomic Energy Commission site in order to compute the surface erosion rate. Monthly rainfall data, for the period 2003-2012 were used to compute annual rainfall erosivity indices for the site, using the Modified Fournier index. Values ...

The amount of rainfall received over an area is an important factor in assessing availability of water to meet various demands for agriculture, industry, irrigation, generation of hydroelectricity and other human activities. Over the study period of recent 30 years, trend values of monsoon average rainfall in Sylhet have decreased. This paper has measured the correlation coefficients between ra...

Vegetation productivity is an essential variable in ecosystem functioning. Vegetation dynamics of dryland ecosystems are most strongly determined by water availability and consequently by rainfall and there is a need to better understand how water limited ecosystems respond to altered rainfall amounts and variability. This response is partly determined by the vegetation functional response to r...
