The Charf El Akab aquifer has a surface area of 17 km2 and is located about 20 km southwest of the Tangier city, it circulates in the Miocene sandy basin of the same name and comprises two layers, one high and the other low, these two are separated in some places by an airtight impenetrable sand-marly formation. The requirements for water whether potable or industrial, in the Tangier-Asilah region are expected to amplify in order to support the increasing demand prompted by the economical development, population growth as well as the heightened threat of scarcity related to climate change. Currently, the water supply of this region is ensured mostly by the two dams: Ibn Battouta and “April 9, 1947”. However, this aquifer plays the role of an easily usable emergency reservoir, in case of an extra water supply in rush hour or in the event where current service works of the cities of Tangier and Asilah are unavailable. Nevertheless, water resources are still vulnerable because of the existence of abandoned quarries in the area. Therefore, the protection of this aquifer against any source of pollution is the purpose of this work. The lower water layer is the only one that can be exploited by the ONEE (National Office for Electricity and drinking Water), due to the fact that it has a better quality and very good hydrodynamic characteristics. The most important thing about this work is the establishment of an intrinsic vulnerability map to the pollution by the dRASTIC method, by exploiting of the calibrated hydrodynamical model results. In the same context of protection, a guesstimate of the close protection perimeter of 72.76 ha was acquired, using a new numerical modeling approach by the “Arcfem” software under the ArcMap environment.

In this paper, we study non-abelian extensions of 3-Lie algebras through Maurer-Cartan elements. We show that there is a one-to-one correspondence between isomorphism classes of non-abelian extensions of 3-Lie algebras and equivalence classes of Maurer-Cartan elements in a dGLA. The structure of the Leibniz algebra on the space of fundamental objects is also analyzed.

在缓慢变形监测中,造成差分干涉测量(d-InSAR)技术误差的一个主要原因是对流层的不均一性所致。因为在两次雷达获取影像过程中气候条件有很大的差异性,并在差分干涉图中形成干扰的条纹。这些对干涉图产生很大的影响,需要在变形测量中给予剔除。本文提出一种在干涉测量中能够同时减少全局和局部对流效应的方法。首先,它要求利用稳定散射体来形成大量的、连续的多时相干涉图,全局大气校正是基于相位和地形,局部校正则基于干涉图之间的相关性。结合GPS技术测量科林斯海湾地表形变的结果验证该技术是有效的,实验数据包括81幅差分干涉图。

The relationship between the ability to split off the center-of-mass motion,the idea of a"guiding center"and its connection with some form of generalized Galilean,or Newton-Hooke-type,"kinematic symmetry[1]"has been the subject of a number of recent papers[2-3].In the presence of magnetic fields this is the subject of Kohn’s theorem and its *** use of the guiding center approximation in plasma physics is well *** well explored is the application of these ideas to gravitational *** is
