Multi-risk assessments are being increasingly proposed as a tool to effectively support policy-makers in reducing impacts from natural hazards. The complexity of multi-risk requires assessment approaches capable capturing multiple components risk (e.g., different hazards, exposed elements, and dimensions vulnerability) coherent frame reference, while at the same time providing an intuitive entr...

This study was carried out for the purpose of investigating the issue of tailings dams as a potential source of contamination by trace elements in soils at the Sidi Bou Othmane mine in the Marrakech Region, Morocco. Soil samples taken from depths of up to 15 cm and within a radius of 50 m from the tailings dams, were analyzed for Cd, Cu, Pb and Zn using atomic absorption spectrometry. Average c...

this study was carried out to 1. determine spatial variations of heavy metal deposition in agricultural soils of two rural communities (ouledbouaicha and tazakourte) of about 5790 ha in a mining area near marrakech city in morocco; 2. to assess the extent of metallic pollution generated by the mining activity and; 3. to identify the key mechanism responsible for this contamination and its relat...

The paper presents a comprehensive closed-form performance analysis framework for multihop millimeter wave (mmWave) communications as a potential scheme in the next fifth generation (5G) systems and Internet of things (IoT) applications. To take into consideration the channel fading in the mmWave range, we adopt the advocated Weibull model for its flexible ability to cover different channel con...

Riad and dar ‘house’ are frequently confused, but with the following elements, we can tell difference. Riads likewise larger more spacious than dars, although not to level “ground floor + first floor”, as they designed for almost four generations of same family under one roof. feature an exterior façade comprising a blind wall 8 meters high, completely neutral, nearly no windows. These were ere...
