2013/3/11
The REE signature of banded iron formations (BIF) and martite-goethite mineralization of the Njweng ridge (South Cameroon) are used here to decipher the nature of the ocean during the period of BIF pr...
Identifying Pathfinder Elements for Gold in Multi-Element Soil Geochemical Data from the Wa-Lawra Belt, Northwest Ghana: A Multivariate Statistical Approach
Multivariate Analyses Multi-Elements Soil Geochemical Data
2013/3/7
A multivariate statistical analysis was performed on multi-element soil geochemical data from the Koda Hill-Bulenga gold prospects in the Wa-Lawra gold belt, northwest Ghana. The objectives of the stu...

The inversion of tide-gage records to determine the initial state results in the least square inversion of a rectangular system of linear equations. When the inversions are unconstrained, we found tha...
In recent times, enormous damage has been caused by dyke failures during and after river flood disasters throughout the world. Besides extreme meteorological conditions the reasons for these failures ...
Elements at risk as a framework for assessing the vulnerability of communities to landslides
Elements framework vulnerability communities landslides
2009/12/30
The assessment of the vulnerability of communities prone to landslide related disasters is a topic that is growing in importance. Few studies discuss this issue and limited research has been carried o...
Assessing the efficiency and the criticality of the elements belonging to a complex territorial system subject to natural hazards
efficiency criticality elements complex territorial system subject natural hazards
2009/12/29
The effects of natural hazards can be mitigated by the use of proper "pre-event" interventions on "key" elements of the territory, that is on elements that are mostly vulnerable to a given catastrophi...
