I recall, more than a decade ago, sitting in my tent in some boreal wilderness and being able to read my e-mail. To do so, all I needed was a small strap-on device that enabled my laptop to access the phone network. Back then, my IT department assured me that such accessories would soon be built in to all computers. And the advent of 3G promised high-speed, low-cost, hasslefree online access ev...

To evaluate the state of ecosystems in Mauritania, rainfall time series and a GIMMSNDVI (global inventory modeling and mapping study-normalized difference vegetation index) data set were used for analysis of rainfall and NDVI trends and their relationships in different ecological zones. Linear regression analysis and the non-parametric Mann-Kendall test were applied to detect NDVI and rainfall ...

In this paper, the study was conducted across the country to assess the rainfall trend in different climate zones of Pakistan over the past three decades. For this purpose dataset comprising 30 years for the period 1976 to 2005 were acquired from 30 meteorological observatories from different parts of the country. The whole data was analyzed through Analysis Of Variations (ANOVA) along Dunnett ...

Here we present some results that would possibly have attracted the attention of physics community in early days quantum mechanics such a way its development could been different from what see today. We will first derivation Planck's blackbody spectrum radiation without hypothesis quantized energy levels oscillator, only additional to classical theory being existence zeropoint fluctuations elec...

Rainfall variability and its impact on water resources are important climatic issues. Intra-annual variations in rainfall are characterized as precipitation concentration index (PCI). Another feature that directly correlates with the concentration of precipitation is the rain erosivity (Modified Fournier Index MFI). The aim of this study is to investigate the PCI and MFI indices and map their s...

This paper presents an analysis of the interaction between the various variables associated with Rift Valley fever (RVF) such as the mosquito vector, available hosts and rainfall distribution. To that end, the varying zones potentially occupied by mosquitoes (ZPOM), rainfall events and pond dynamics, and the associated exposure of hosts to the RVF virus by Aedes vexans, were analyzed in the Bar...

Saffron is grown in arid and semi-arid regions in Iran in late autumn, winter and late spring with rainy season. It should be irrigated by supplemental basin irrigation. Since rainfall is usually delayed in autumn, therefore, a pre-flowering irrigation of about 100 mm is needed. In areas with a seasonal rainfall of 600 mm a post- flowering irrigation of about 50 mm is adequate for economical yi...

This study aims to evaluate two methods of surface water routing including kinematic wave and time-area in upstream of the Bustan dam. To this end, first considering the features and application prerequisites of both methods and describing the hydraulic and hydrologic conditions within the Tamer watershed, algorithms and scripts of kinematic wave and time-area methods were developed. Then the s...
