This study presents va.ious a.proa.hes to ca.cula.ing the bea.ing ca.a.ity of sprea. footings a.plied to the rock ma.s of the western corniche a. the tip of the da.a. peninsula. The bea.ing ca.a.ity wa. estima.ed using empirica., a.a.ytica. a.d numerica. a.proa.hes ba.ed on the pa.a.eters of the rock ma.s a.d the founda.ion. La.ora.ory tests were ca.ried out on ba.a.ite, a. well a. on the other fa.ies detected. The results of these studies give a.ra.ge of a.lowa.le bea.ing ca.a.ity va.ues va.ying between 1.92 a.d 11.39 MPa.for the empirica. methods a.d from 7.13 to 25.50 MPa.for the a.a.ytica. methods. a.wide dispersion of results wa. observed a.cording to the different a.proa.hes. This dispersion of results is expla.ned by the use of different rock pa.a.eters depending on the method used. The a.lowa.le bea.ing ca.a.ity results obta.ned with va.ying a.proa.hes of ca.cula.ion rema.n a.missible to support the loa.s.

Huntington’s disea.e is a.neurodegenera.ive disea.e ca.sed by the expa.sion muta.ion of a.cytosine-a.enine-gua.ine triplet in the exon 1 of the HTT gene which is responsible for the production of the huntingtin (Htt) protein. In physiologica. conditions, Htt is involved in ma.y cellula. processes such a. cell signa.ing, tra.scriptiona. regula.ion, energy meta.olism regula.ion, dNa.ma.ntena.ce, a.ona. tra.ficking, a.d a.tia.optotic a.tivity. When the genetic a.tera.ion is present, the production of a.muta.t version of Htt (mHtt) occurs, which is cha.a.terized by a.plethora.of pa.hogenic a.tivities tha., fina.ly, lea. to cell dea.h. a.ong a.l the cells in which mHtt exerts its da.gerous a.tivity, the Ga.a.rgic Medium Spiny Neurons seem to be the most a.fected by the mHtt-induced excitotoxicity both in the cortex a.d in the stria.um.

From a.clinica. point of view, Huntington’s disea.e is cha.a.terized by a.wide spectrum of symptoms spa.ning from motor impa.rment to cognitive disorders a.d dementia.
