In Morocco, as in several regions of the world, field instabilities are one of the most serious problems on several levels: social, economic and environmental. This study is aimed at the safety of people, the protection of infrastructures and the environment, and on the other hand the forecasting of areas to be avoided for future development. Landslides are polygenic sets that result from the combined action of complex factors. Some, permanent factors, create the essential conditions for instabilities; the others, called dynamic factors, act under the dependence of the former and play the role of detonator. The geological complexity of the land concerned, the diagnosis of the phenomenon is sometime delicate. Risk prevention and protection of populations require, at least for the most threatening sites, delicate and costly studies and recognitions. To stabilize and delineate the damage, several solutions have been proposed and based on the use of various techniques. On the other hand, the preparation of a guide of the stabilization to reinforce the unstable areas has a paramount importance for the development of the regions, which are subjected to rapid and often disorderly urban growth.

Today we note a gradual interest and a growing awareness to the new role assigned to local authorities and their relation to sustainable development; and that, since the adoption of Agenda 21 by more than 170 countries who took part in the Earth Summit held in Rio in Brazil in 1992. This global planning document is presented as a set of action programs and an indicative plan for central and territorial governments, which aims to improve the indicators of sustainable development through the effective and efficient involvement of local authorities. However, this course depends on the degree of commitment of these entities.

The development of fungi in stored grains present a health risk to customers due to their ability to produce and accumulate mycotoxins. Then, chemical antifungal agents are applied to grains to reduce their contamination by molds. The aim of the present study was to evaluate the antifungal potency of oregano essential oil and thymol on some species of fungi involved in corn spoilage. Molds were isolated, and then identified by their macroscopic and microscopic characteristics after cultivation on standard media. The antifungal activity of oregano essential oil and tymol was conducted by broth dilution method. The mold species isolated were Aspergillus niger, Aspergillus flavus, Penicillium sp., Fusarium sp., and Mucor sp. Oregano essential oil and thymol demonstrate an antifungal effect against all these isolates. These compounds may be useful as alternative in limiting or preventing the development of harmful fungi and mycotoxins in food.

The main objective of this study is to qualitatively evaluate the degree of implementation of actions and educational activities for health facilities in the F

Discharges from dairies are very rich in organic matter. 900 m3/d of liquid waste is discharged daily by the milk processing unit of the City Rabat / Sal

The lactose in cheese whey is an interesting substrate for the production of bulk commodities such as bio-ethanol, due to the large amounts of whey surplus generated globally. In the present context of increasing demand for energy and biofuel, the microbial synthesis of ethanol using industry waste materials has gained recent importance. The present study deals with the ethanol production from whey-a dairy waste by using potential thermotolerant immobilized yeasts isolates in free and immobilized state. Two species of thermotolerant yeasts strains, Candida inconspicua, Candida xylopsoci and standard culture of K. marxianus were used for bioethanol production. Of the selected thermotolerant yeast species, Candida inconspicua W16 exhibited the maximum production of ethanol (3,9
