This thesis aims to identify landslide risk zones in Haiti as a whole (regional scale) and Port au Prince specifically (local scale) and to evaluate how this landslide risk can affect them, especially to Port au Prince, in order to elaborate recommendations in priority zones of the city. Landslide risk priority zones are marked in order to apply land management recommendations supported in the Haitian land tenure to reduce, mitigate or delete at maximum the possible damages that these zones can suffer in the future due to landslides. These recommendations are collected in order to stakeholders decide which of them are the best options for each priority zone. Different types of maps are generated in order to locate all landslide risk zones and priority zones.

In order to evaluate ground shaking characteristics due to surface soil layers in the urban area of Port-au-Prince, short-period ambient noise observation has been performed approximately in a 500x500m grid. The HVSR method was applied to this set of 36 ambient noise measurement points to determine a distribution map of soil predominant periods. This map reveals a general increasing trend in the period values, from the Miocene conglomerates in the northern and southern parts of the town to the central and western zones formed of Pleistocene and Holocene alluvial deposits respectively, where the shallow geological materials that cover the basement increase in thickness. Shorter predominant periods (less than 0.3 s) were found in mountainous and neighbouring zones, where the thickness of sediments is smaller whereas longer periods (greater than 0.5 s) appear in Holocene alluvial fans, where the thickness of sediments is larger. The shallow shear-wave velocity structure have been estimated by means of inversion of Rayleigh wave dispersion data obtained from vertical-component array records of ambient noise. The measurements were carried out at one open space located in Holocene alluvial deposits, using 3 regular pentagonal arrays with 5, 10 and 20m respectively. Reliable dispersion curves were retrieved for frequencies between 4.0 and 14 Hz, with phase velocity values ranging from 420m/s down to 270 m/s. Finally, the average shear-wave velocity of the upper 30 m (VS30) was inverted for characterization of this geological unit.

After the 2010 Haiti earthquake, that hits the city of Port-au-Prince, capital city of Haiti, a multidisciplinary working group of specialists (seismologist, geologists, engineers and architects) from different Spanish Universities and also from Haiti, joined effort under the SISMO-HAITI project (financed by the Universidad Politecnica de Madrid), with an objective: Evaluation of seismic hazard and risk in Haiti and its application to the seismic design, urban planning, emergency and resource management. In this paper, as a first step for a structural damage estimation of future earthquakes in the country, a calibration of damage functions has been carried out by means of a two-stage procedure. After compiling a database with observed damage in the city after the earthquake, the exposure model (building stock) has been classified and through an iteratively two-step calibration process, a specific set of damage functions for the country has been proposed. Additionally, Next Generation Attenuation Models (NGA) and Vs30 models have been analysed to choose the most appropriate for the seismic risk estimation in the city. Finally in a next paper, these functions will be used to estimate a seismic risk scenario for a future earthquake.

El cáncer mamario humano (CMH) es un gran problema de salud puesto que es el cáncer que más frecuentemente se diagnostica en la mujer y es la segunda causa de muerte por cáncer. El cáncer mamario inflamatorio (CI) humano y canino (CIH y CIC, respectivamente) es un tipo de cáncer mamario especialmente agresivo de baja prevalencia. El CIC se ha propuesto como modelo para el estudio de la enfermedad humana. El CI se define como una entidad clínicopatológica caracterizada clínicamente por edema difuso, eritema y dolor de la mama, ocupando la mayor parte de la misma y, frecuentemente, sin presentar nódulo mamario, lo que complica el diagnóstico al poder confundirse con una dermatitis o una mastitis. Por otro lado, los tumores mamarios caninos (TMC) se presentan como el primer grupo de tumores en la perra, suponiendo un 52% de todas las neoplasias y el segundo tras los tumores cutáneos teniendo en cuenta ambos sexos. En la especie canina el CI representa el 7,6% de todos los tumores mamarios caninos y el 17% de todas las neoplasias mamarias malignas. Una gran parte del conocimiento sobre el cáncer mamario humano (CMH) se basa en las investigaciones realizadas in vitro o in vivo. En numerosas ocasiones se han propuesto los TMC espontáneos como modelo para el estudio del CMH. Como previamente se ha indicado, se ha demostrado que la perra es un buen modelo animal para el estudio del CIH, ya que tienen características epidemiológicas, clínicas e histológicas similares. Sin embargo, la mayoría de los aspectos comparables en los cánceres de mama de ambas especies, incluyendo el perfil hormonal o la presencia de ciertas citocinas, no han sido todavía evaluados...
