Consequence of the sea level rise (SLR) on the Mediterranean coastal areas in Egypt, particularly the Nile River Delta, has become an issue of major concern to Egypt’s population and the government. Previous publications disregard the entire Mediterranean coast of Egypt as an integral unit...

Rainfed lowlands in inland valleys present a high potential for rice (Oryza spp.) production in West Africa. However, rice yield in the lowlands is, in general, low due to various constraints such as poor soil fertility, drought, iron (Fe) toxicity, and poor crop management practices. The...

An influential theoretical literature has observed that economic diversification can reduce risk and increase financial development. But causality operates in both directions, as a well functioning financial system can enable a society to invest in more productive but risky projects, thereby...

This study summarizes an analysis of uniform, topographical and other site-specific soil fertility testing procedures based on observations of various crops at various locations in North Dakota and one location in Minnesota for 2001 through 2004. Results showed little difference in economic...

Economic activity is risky. Returns across economic sectors can be highly variable, potentially causing costly adjustments to consumption. However, when returns are imperfectly correlated across sectors and insurance is unavailable, diversification can reduce the economic impact of shocks....

This paper presents a short history of the appraisal of laser scanner technologies in geosciences used for imaging relief by high-resolution digital elevation models (HRDEMs) or 3D models. A general overview of light detection and ranging (LIDAR) techniques applied to landslides is given,...

In recent years, new remote-sensed technologies, such as airborne and terrestrial laser scanner, have improved the detail and the quality of topographic information, providing topographical high-resolution and high-quality data over larger areas better than other technologies. A new generation...

The main result of this article states that one can get as many as D+1 modes from just a two component normal mixture in D dimensions. Multivariate mixture models are widely used for modeling homogeneous populations and for cluster analysis. Either the components directly or modes arising from...
